Title: Luminaire with adjustable illumination pattern

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure generally relates to illumination, and more particularly to illumination devices and systems with adjustable illumination patterns. 
     2. Description of the Related Art 
     Luminaires enjoy widespread use in a variety of industrial, commercial, and municipal applications. Such applications can include general or area lighting of workspaces, roadways, parking lots, and the like. Multiple luminaires are typically arranged in patterns and positioned at intervals sufficient to provide a minimum overall level of illumination across the area of interest. For example, luminaires may be spaced at intervals along a driveway in a multilevel parking garage to provide an overall level of illumination that permits safe ingress and egress by pedestrians as well as permits safe operation of motor vehicles within the parking garage. In a similar manner, luminaires may be spaced at intervals throughout a commercial center parking lot to promote safe operation of motor vehicles, permit safe ingress and egress by customers, and foster a sense of safety and well-being for business patrons within the commercial center. Similarly, a number of luminaires may be spaced along a roadway to provide a level of illumination permitting safe operation of motor vehicles on the roadway and, where applicable, safe passage of pedestrians on sidewalks adjoining the roadway. 
     To simplify power distribution and control wiring, such luminaires may be organized into groups or similar hierarchical power and control structures. For example, multiple luminaires along a roadway may be grouped together on a common power circuit that is controlled using a single, centralized controller to collectively adjust the luminous output of all of the luminaires in the group. In another instance, multiple luminaires within a parking garage may be controlled using a single photocell mounted on the exterior of the parking garage. Such installations may however compromise operational flexibility for ease of installation and simplicity of operation. 
     Energy conservation has become of ever-increasing importance. Efficient use of energy can result in a variety of benefits, including financial benefits such as cost savings and environmental benefits such as preservation of natural resources and reduction in “green house” (e.g., CO 2 ) gas emissions. 
     Residential, commercial, and street lighting which illuminate interior and exterior spaces consume a significant amount of energy. Conventional lighting devices or luminaires exist in a broad range of designs, suitable for various uses. Lighting devices employ a variety of conventional light sources, for example incandescent lamps, fluorescent lamps such as high-intensity discharge (HID) lamps (e.g., mercury vapor lamps, high-pressure sodium lamps, metal halide lamps). 
     One approach to reducing energy consumption associated with lighting systems employs higher efficiency light sources. Use of higher efficiency light sources may, for instance, include replacing incandescent lamps with fluorescent lamps or even with solid-state light sources (e.g., light emitting diodes (LEDs), organic LEDs (OLEDs), polymer LEDs (PLEDs)) to increase energy efficiency. In some instances, these higher efficiency light sources may present a number of problems. For example, fluorescent light sources may take a relatively long time after being turned ON to achieve their full rated level of output light or illumination. Such light sources also typically have a high energy consumption during warm-up. Many higher efficiency light sources emit light with a low color rendering index (CRI). For reference, sunlight has a CRI of 100 and represents “ideal light” which contains a continuous spectrum of visible radiation. Low CRI light is less pleasing to the human eye. Surfaces illuminated with low CRI light may not be perceived in their “true” color. Low CRI light makes it more difficult to discern details, often requiring a higher level of output light or illumination to discern details that would otherwise be discernable in high CRI light. Further, higher efficiency light sources may require additional circuitry (e.g., ballasts) and/or thermal management techniques (e.g., passive or active cooling). 
     Lighting systems are designed to have specific illumination patterns, for example, outdoor luminaires may have National Electrical Manufacturers Association (NEMA) Type 1, 2, 3, 4 or 5 illumination patterns. Indoor applications may require unique illumination patterns to properly light complex interior spaces, for example retail stores. Other non-standardized light patterns are desirable in some installations, to provide higher light levels in certain locations and lower light levels in other locations. For example, a NEMA Type 5 outdoor luminaire is designed to provide light in a square or circular pattern on the ground, whereas a NEMA Type 3 pattern has an oblong light distribution more suitable for roadway lighting. In some installations, none of the standard illumination patterns are acceptable. For example, a NEMA Type 5 luminaire mounted near a residence may properly illuminate a yard and driveway, but may also project an objectionable amount of light into the windows of the residence. In such a case the luminaire installer may receive a complaint from the resident and then return to the installation to install a light shield or mask, or paint the luminaire&#39;s refractor to reduce the objectionable light illuminating the residence. This is a very expensive alteration due to the time and cost of a “bucket truck” and service person. 
     Interior light distribution patterns may require more than one luminaire to achieve appropriate light levels in all areas. Most lighting stores, utilities, electric companies, rural electric cooperatives and other providers of luminaire installations stock several types of luminaires so that the proper illumination pattern luminaire will be available for installation in any situation. This is a significant expense in inventory and record keeping, and complicates the installation plan.

     DETAILED DESCRIPTION 
     In the following description, certain specific details are set forth in order to provide a thorough understanding of various disclosed embodiments. However, one skilled in the relevant art will recognize that embodiments may be practiced without one or more of these specific details, or with other methods, components, materials, etc. In other instances, well-known structures associated with the various embodiments have not been shown or described in detail to avoid unnecessarily obscuring descriptions of the embodiments. 
     Unless the context requires otherwise, throughout the specification and claims that follow, the word “comprising” is synonymous with “including,” and is inclusive or open-ended (i.e., does not exclude additional, unrecited elements or method acts). 
     Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Additionally, the terms “lighting,” “luminous output” and “illumination” are used herein interchangeably. For instance, the phrases “level of illumination” or “level of light output” have the same meanings In addition, for instance, the phrases “illumination source” and “light source” have the same meanings 
     As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. It should also be noted that the term “or” is generally employed in its broadest sense, that is, as meaning “and/or” unless the context clearly dictates otherwise. 
     The headings and Abstract of the Disclosure provided herein are for convenience only and do not interpret the scope or meaning of the embodiments. 
     Implementations of the present disclosure are directed to systems and methods that eliminate or reduce the need for a utility or luminaire distributer to stock luminaires with different illumination patterns and reduce or eliminate the need for pre-planning installations. Further, one or more implementations disclosed herein may allow for adjusting illumination patterns of luminaires wirelessly from the ground or from a central location using a supervisory control and data acquisition (SCADA) system, and provide for a wider variety of illumination patterns than the standardized patterns. Such adjustments may be made in response to customer complaints about a particular lighting pattern or in response to a change in the area to be illuminated, for example. 
     In addition, one or more implementations of the present disclosure allow scheduled dimming of luminaires, dimming in defined physical directions and scheduled adjustment of light patterns. The luminaires of the present disclosure may provide different light color illumination, such as amber color, in defined zones which may be required in biologically sensitive areas or other applications. As another example, notifications, such as severe storm warning alerts, may be signaled to the public by turning on or flashing an amber colored or other colored LED arrays. 
     Generally, implementations of the present disclosure provide a solid-state luminaire that includes one or more arrays of one or more solid-state light sources (e.g., LEDs) each. The luminaires may include an LED driver that includes an output channel for each of the LED arrays and on/off and/or dimming control for each LED driver channel. The luminaires may also include a controller capable of adjusting the dimming level or on/off state of one or more of the driver channels, and a communications method (wired or wireless) or a physical input, such as a switch, which sets dimming schedules and levels for each LED driver channel. The luminaires may further include support circuitry such as voltage surge suppression and electromagnetic interference (EMI) filtering, a housing and lens or cover window, and a photo sensor coupled to the controller for local “dusk to dawn” control of the light output. The luminaires may also include various hardware components for mounting the luminaires in the field. 
     Light emitted from LEDs of the LED arrays may be directed by the physical position of each of the LED arrays in the luminaire, and/or by reflective, refractive or diffractive optics, such that different areas may be illuminated when a respective LED driver channel is enabled or the dimming value of the LED driver channel is changed. The areas illuminated by the individual LED arrays may overlap partially or completely, or may be separate. 
     In some implementations of the present disclosure, the communications method is via a power line carrier (PLC) or a power line data communication system. In these implementations, decoupling and filtering circuits may extract data from power lines for use by PLC or power line data systems, and transmitters/drivers may insert data into a power line for communication over the power line. Such features are discussed in detail below. 
     In some implementations, the communications method is wireless control such as Bluetooth®, WiFi®, Zigbee®, or the like. In these implementations, the illumination pattern of a luminaire may be adjusted either in the field by use of a smart device or appliance, such as a smart phone, tablet computer or notebook computer, during installation and/or after installation. For example, if a customer has complained about light trespass, a minimally trained worker may be dispatched to the site, and may use a smart appliance to dim the light output on a side of one or more luminaires toward the area of trespass. Additionally or alternately, the light pattern of a luminaire may be adjusted at a central location prior to installation or after installation using the smart appliance or a computer with wired or wireless networking capabilities. 
     In some implementations, a luminaire may have four white light emitting LED arrays and a four-channel LED driver operative to enable/disable and/or dim the LEDs on the four respective LED arrays. As discussed further below, the LED arrays and optics may be arranged such that the LED arrays direct light toward the four ordinate directions from a luminaire&#39;s mounting axis. For example, if the mounting axis is perpendicular to a street, a first LED array may illuminate in the direction crossing the street, a second LED array may illuminate in the direction of a sidewalk/house, a third LED array may illuminate in one direction of the traffic flow, and a fourth LED array may illuminate in the other direction of traffic flow. By orienting the light output from the LED arrays in this manner, various light patterns (e.g., NEMA Type 1, NEMA Type 2, NEMA Type 3, NEMA Type 4, NEMA Type 5) may be substantially produced by the luminaire. In any of the produced illumination patterns, a portion of or the entire luminaire output may be dimmed by dimming one or more of the LED driver channels. 
     For example, a drive current or a pulse width modulated (PWM) duty cycle of each of the LED arrays may be set to substantially the same value, thereby setting the light output of each of the LED arrays to be substantially equal. In this example, equal light output of all the LED arrays of a luminaire may form a NEMA Type 5 light pattern on the ground. Alternatively, some of the LED arrays may be dimmed or turned off completely so that the luminaire generates other types of standardized or custom illumination patterns. 
     The luminaires of the present disclosure may be programmed to generate standard beam shapes such as Illuminating Engineering Society of North America (IESNA) or NEMA beam types as well as individually customized beam shapes, including shapes having uneven light distribution with added or subtracted amounts of light in small areas. 
     In some implementations, a diffuse window or lens placed over the LED arrays forms a weather shield and diffuses the LED light such that an aesthetically pleasing light pattern is formed, without visual “hot spots” or other objectionable irregularities in light output. 
     In another implementation, a luminaire may include a number (e.g., three) of LED arrays which are amber color emitting LED arrays positioned on a house facing side of the luminaire and the two street facing sides of the luminaire perpendicular to the mounting axis of the luminaire, and one white light emitting LED array on the street facing side of the luminaire. This implementation may be programmed by local wireless communications via a smart appliance for scheduled dimming, such that the white light emitting LED array may be turned off during a biologically sensitive season, for example, a sea turtle egg laying/hatching season. Additionally, in this example, the number of amber LED arrays may be dimmed during this season. 
     In some implementations, the multiple LED arrays may be assembled or carried on one printed circuit board (PCB) or may be assembled or carried on separate PCBs. For example, the LED arrays may be assembled on one or more flexible PCBs which may be attached to a mounting area on the luminaire by thermally conductive adhesive, or other attachment method. The mounting area may be a flat plane, a raised polygon, a raised curved or cylindrical boss, or a convex and/or concave surface, for example. Light distribution for a particular illumination pattern may be made by selecting the appropriate shape of mounting surface during manufacturing of the luminaire. Further, one or more refractive, diffractive or reflective optical elements may be used to direct the light from the LED arrays to form the appropriate illumination pattern. 
       FIG. 1  shows a schematic block diagram of a luminaire  100  coupled to an alternating current (AC) power source  102  in accordance with an implementation of the present disclosure. The luminaire  100  includes four LED arrays  104 A- 104 D (collectively LED arrays  104 ) each including a plurality of LEDs  106 . The luminaire  100  includes input conditioning circuitry  108  coupled to the AC power source  102  which may include voltage surge suppression devices, such as metal oxide varistors (MOV), electrical noise filtering circuitry, and/or over current protection circuitry. 
     The luminaire  100  may also include a communications interface or control input section  110  connected to a wireless input  112  (e.g., transceiver), a wired input  114  (e.g., universal serial bus (USB)), or a mechanical switch input  116  which are used to set or control the operational mode of the luminaire. The luminaire  100  may also include a controller  118  in the form of a processor-based microcontroller or other logic element or elements, as discussed further below. 
     The communications interface  110  may permit wireless communication, wired communication or other methods for controlling the brightness and/or other characteristics of the LEDs  106  of the LED arrays  104 . For example, a “0 to 10V” dimming control may be incorporated. As another example, a Bluetooth® Smart wireless control may be provided. A photo control to switch the luminaire  100  on or off depending upon the natural ambient light may also be incorporated. A ZigBee° wireless interface may be used for communication between individual luminaires, or between a base station (not shown) and the luminaires, or between a smart appliance and the luminaires, to control the operation and/or other characteristics of the luminaires. 
     The luminaire  100  may also include a multichannel LED driver  120  operatively coupled to the controller  118 . The LED driver  120  may take one of many forms, for example, a primary power converter followed by two or more individual drivers, or a primary power converter connected to two or more secondary output converters. As an example, the primary converter may be a power factor corrector (PFC) with a high voltage bus, for example a 450 VDC bus. In this example, the secondary converters may be Buck, Flyback, LLC Resonant, or any other switching power down-converter topology, for example. As another example, a non-switching power controller, such as a directly connected “AC LED,” with a suitable semiconductor switch added to control output light level, may also be used. 
     One or more channels of the LED driver  120  may be adjustable by a signal or signals  122  provided by the controller  118  so that power delivered to the LED arrays  104  connected to the respective channels of the LED driver via wires  124  may be controlled, thereby changing the light output from a particular LED array. The signal or signals  122  may be a pulse width modulated (PWM) signal, a 0 V to 10 V analog signal, an I 2 C signal, or any other suitable control signal. 
     The channel power control for the LED driver  120  may be implemented, for example, by adjusting an analog current sink, an analog current source, a solid-state switch positioned in the low side or high side of the current path of each of the LED array  104 , or by an integrated circuit input control of the controller  118 , such as a “dimming input” or enable input. PWM dimming may also be used. 
     Dimming levels of each LED driver channel of the LED driver  120  may be adjusted by the controller  118  to set the illumination pattern for the luminaire. For example, a NEMA Type 5 illumination pattern may be obtained by setting all LED driver channels to the same drive current. If, for example, it is determined that the luminaire  100  causes an undesirable amount of light “trespass” for a residence located proximate the luminaire, the NEMA Type 5 lighting pattern may be modified by adjusting the light output of the LED driver channel that illuminates the “residence side” of the illumination pattern to output a lower level of light to decrease light “trespass” illumination of the residence. 
       FIGS. 2 and 3  show an implementation of a luminaire  200  having four LED arrays  202 A- 202 D ( FIG. 3 ), wherein each of the LED arrays have a plurality of LEDs  204 . The LED arrays  202 A- 202 D are assembled on four printed circuit boards  206 A- 206 D, respectively, with thermally conductive adhesive used for both mounting and thermal interface to a cuboid shaped boss or heat exchanger  208  of the luminaire  200  that projects downward from an interior reflective surface  210  of a housing  212 . The boss or heat exchanger  208  may be physically and thermally coupled to the housing  212  so that heat from the heat exchanger may be dissipated through the housing. In some implementations, the printed circuit boards  206  may comprise a single flexible circuit board “wrapped” around the heat exchanger  208 . The LED arrays  202  are arranged such that the LEDs  204  direct light toward the four ordinate directions from a mounting axis  214  of the luminaire  200  that is perpendicular to a street when the luminaire is installed. The mounting axis  214  for the luminaire  200  is shown in  FIGS. 2 and 3 . Additionally, a house side  216 , front street side  218 , left street side  220 , and a right street side  222  of the luminaire  200  are shown as per the NEMA outdoor light pattern standards. 
     A lens  224  ( FIG. 2 ) may be mounted on the housing  212  for weather protection and light diffusion. The lens  224  is shown as being separated from the housing  212  for explanatory purposes. The lens  224  may be placed around the LED arrays  202  to protect the LEDs  204  from moisture or other physical damage, and to diffuse light generated by the LEDs so that the light has a pleasing appearance. The lens  224  may include refractive or diffractive properties which may be used to produce a desired light pattern. In addition, the lens  224  may be coated with a dielectric reflective coating that selectively reflects some wavelengths of light while transmitting other wavelengths of light. In some implementations, there may be a reflective surface around the LEDs  204  that is coated with a wavelength converting phosphor that changes the color temperature of the emitted light in order to provide a more useful or pleasing appearance. 
       FIGS. 4 and 5  show another implementation of a luminaire  300  that includes one or more LED arrays  302  each having a plurality of LEDs  304 . The LED arrays  302  are positioned on a flexible circuit board  306  disposed around a cylindrically shaped boss or heat exchanger  308  positioned within an interior of a vessel collectively defined by a housing  310  and a lens  312  ( FIG. 4 ). The plurality of LEDs  304  are carried by the circuit board  306  and arranged to generate light to pass through the lens  312  during operation. The LEDs  304  each have a respective principal axis of emission, which typically extends perpendicularly from an outer surface of the LEDs. In this implementation, the LEDs  304  are advantageously arrayed about a central or longitudinal axis, with their respective principal axes of emission extending radially outward from the central or longitudinal axis, for example in a 360° pattern. 
     In some implementations, the LEDs  304  may be grouped into a plurality of individually controllable LED arrays  302 . For example, in the illustrated implementation the LEDs  304  are arranged in 12 vertical columns spaced about the central axis of the cylindrically shaped heat exchanger  308 . In some implementations, each of the 12 columns may be individually controllable by a channel of an LED driver, such as the LED driver  120  shown in  FIG. 1 . As shown in  FIG. 6 , each of the  12  LED arrays  302  may be used to control illumination in respective areas  600 A- 600 L around the luminaire  300 . In the illustrated implementation, each of the areas  600 A- 600 L includes a  30 ° section of area around the luminaire  300 . In practice, each of the areas  600 A- 600 L may be overlapping or non-overlapping. Additionally, in some implementations the 12 LED arrays may be grouped into fewer or more individually controllable LED arrays  302 . For example, in some implementations, the luminaire  300  may include four individually controllable LED arrays that each include three adjacent columns of the  12  columns of LEDs spaced about the heat exchanger  308 . In such implementation, each LED array  302  may be used to control illumination over approximately a 90° section of area around the luminaire, similar to the luminaire of  FIGS. 2 and 3 . 
     The LEDs  304  may be mounted on the flexible or bendable printed circuit board  306  or may be mounted on individual rigid printed circuit boards and attached or secured to the heat exchanger  308  to dissipate heat generated by the LEDs  304 . In some implementations, a single flexible or bendable printed circuit board may be disposed completely or nearly completely about a central or longitudinal axis, to form an annulus. In other implementations, a plurality of rigid printed circuit boards may be disposed completely or nearly completely about a central or longitudinal axis, each constituting a respective facet of a polygonal annular shape about the central or longitudinal axis. In yet another implementation, a plurality of flexible or bendable printed circuit boards may be disposed completely or nearly completely about a central or longitudinal axis, each constituting a respective facet of a polygonal annular shape. Use of flexible or bendable printed circuit boards may reduce the total number of facets on the polygonal annular shape. A thermal interface material, such as thermally conductive adhesive or grease, self-adhesive thermally conductive tape, or other such material may be placed between the heat exchanger and the printed circuit board to secure the printed circuit board to the heat exchanger and/or to increase heat conduction from the circuit board to the heat exchanger. 
     In other implementations, the LEDs  304  may be arranged in various other linear or non-linear arrangements. In some instances, greater quantities of low or mid power LEDs may be used in place of higher power (e.g., &gt;1 watt) LEDs to make the collective light source more diffused and/or lower the manufacturing cost of the device. As an example, in some implementations, an array of LEDs may be provided on one or more flexible or bendable printed circuit boards having up to or more than 100 individual LEDs. The one or more circuit boards may be attached or secured to a heat exchanger, such as the heat exchanger  308  shown in  FIGS. 4 and 5 , to dissipate heat generated by the LEDs. 
       FIGS. 7A-7B and 8A-8B  show another implementation of a luminaire  700 . The luminaire  700  includes a housing  702  and a lens  704  that together form an interior vessel. The luminaire  700  includes a flexible PCB  706  coupled a downward facing mounting surface  708  of the housing  702  via a suitable adhesive, such as a thermally conductive pressure sensitive adhesive. The flexible PCB  706  includes four LED arrays  710 A- 710 D each having a plurality of LEDs  712 . Each of the LED arrays  710  is coupled to a multi-channel LED driver  714  via suitable electrical wires  716 . The multi-channel LED driver  714  may be similar or identical to the LED driver  120  of  FIG. 1  discussed above. 
     The housing  702  functions as a heat exchanger for the LEDs  712 . As shown, the housing  702  may include a plurality of fins  716  ( FIG. 7B ), projections, surface treatment, or other features that increase the effective surface area of the housing to enhance its cooling capabilities. In some implementations, the housing  702  may be coated with a nanoparticle surface treatment to increase thermal radiation from its surface. 
     The downward facing mounting surface  708  of the housing  702  may be concave shaped and the flexible PCB  706  may be shaped during installation to match the shape of the mounting surface. In other embodiments, the mounting surface  708  may be convex shaped, planar, or any combination thereof. The mounting surface  708  may be faceted or may have a curvature with a constant radius or otherwise. Other implementations may use discrete PCBs wired together which are mounted to the mounting surface  708  of the housing  702 , or a bendable metal core PCB which is bent or folded to conform to the mounting surface of the housing. 
     The shape of the mounting surface  708  at least partially determines the illumination pattern of the luminaire  700 . For example, in implementations where the mounting surface  708  has a relatively large degree of concavity, the illumination pattern is relatively narrow, whereas in implementations where the mounting surface has a relatively low small degree of concavity, the illumination pattern is relatively spread out. Thus, during manufacturing the shape of the mounting surface  708  may be selected to provide a desired illumination pattern. Moreover, as discussed above, the illumination of each of the four LED arrays  710 A- 710 D may be controlled individually, which allows for numerous illumination patterns for the luminaire  700  after installation of the luminaire. 
     In the implementation illustrated in  FIGS. 7A-7B and 8A-8B , the curved mounting surface  708  is concave about multiple axes (e.g., a longitudinal axis and a lateral axis). In other implementations, the mounting surface  708  may be concave about one or more axes (e.g., doubly concave) or may be convex about one or more axes. 
     The flexible or rigid circuit boards discussed herein may include one or more layers of an electrically insulative or dielectric material. Common materials include FR2, FR3, FR4, aluminum core (ThermaCore, Inc.; Bregquist, Inc.). The circuit boards may include one or more electrically conductive paths carried on one or more layers, or through one or more layers by vias or through holes. Electrically conductive paths may, for example, take the form of one or more traces of electrically conductive material. The circuit boards may take the form of a printed circuit board. 
     The housings and/or heat exchangers (“heat sinks”) discussed herein may take a variety of forms suitable for transferring heat from a solid (e.g., solid-state light sources) to a fluid (i.e., gas or liquid). The heat exchangers may have a dissipation portion which typically includes a relatively large surface area, allowing dissipation of heat therefrom to a fluid (e.g., ambient environment) by convective and/or radiant heat transfer. The dissipation portion may, for example, include one or more protrusions. In some implementations, the protrusions may take the form of fins or pin fins. The heat exchangers may comprise a metal (e.g., aluminum, aluminum alloy, copper, copper alloy) or other high thermal conductivity material. The heat exchangers may, for example, have a thermal conductivity of at least 150 Watt per meter Kelvin (W/mK). 
       FIG. 9  illustrates a map  900  that may be viewable by a processor-based device associated with an illumination system. The map  900  depicts a plurality of icons L 01 -L 23  for plurality of respective luminaires positioned at various locations throughout a geographical area (e.g., a city). The map  900  may be displayed to a user on an output device (e.g., a monitor, touchscreen) of a computing device operative to receive data from the central asset management system. 
     The map  900  may display a window  902  that includes luminaire information for one or more luminaires of the illumination system. In the illustrated example, the window  902  is a pop-up window that displays information for the luminaire depicted by the icon L 14  when a cursor  904  hovers over the icon. In other implementations, the window  902  may be displayed when a user selects one of the icons L 01 -L 23  using any suitable input selection method (e.g., touch, keyboard, manual entry). 
     The information provided in the map  900  or window  902  may be varied or configured as desired for a particular user or a particular application. For instance, a user may be interested in viewing only a particular subset of the luminaires in an illumination system. As non-limiting examples, a user may be interest in viewing only those luminaires that have an expected life of less than one year, only those luminaires that were installed within the past six months, or only those luminaires within a two-mile radius of a service depot. As another non-limiting example, the user may be interested in viewing only a subset of the luminaire information available for each luminaire, such as only the serial numbers of each of the luminaires. 
     For each of the luminaires L 01 , L 04 , L 05 , L 06 , L 10 , L 11 , L 16  and L 18 , the map  900  provides an illustration of respective illumination patterns IP 01 , IP 04 , IP 05 , IP 06 , IP 10 , IP 11 , IP 16  and IP 18  (collectively illumination patterns IP). The illumination patterns IP are patterns the luminaires that have been set by an operator, as discussed above. In some implementations, an operator may be able to select (e.g., touch, click on) one or more of the luminaires L 01 -L 23  displayed on the map  600 , and selectively view or edit the illumination patterns of one or more of the luminaires. 
       FIG. 10  illustrates a schematic block diagram of an illumination system  1000  that includes a power distribution system  1002 , such as an alternating current (AC) network (e.g., power grid or mains) of a utility that includes one or more AC power sources, a central asset management system  1004 , a plurality of outdoor luminaires  1006 , and mobile control systems  1022  positioned proximate each of the luminaires. The particular functional features of the central asset management system  1004  are shown in  FIG. 11 , and the particular functional figures of the luminaires  1006  and the mobile control systems  1022  are shown in  FIG. 12 . 
     Three luminaires  1006  are shown in  FIG. 10 , but it should be appreciated that the number of luminaires may vary depending on a particular application. For example, for applications wherein the luminaires  1006  are part of an illumination system for a city, the number of luminaires may be in the hundreds or even thousands. As discussed further below, the central asset management system  1004  and the plurality of luminaires  1006  are communicatively coupled to a power-line communication system  1008  of the power distribution system  1002  to facilitate communications between the central asset management system and the plurality of luminaires via power lines of the power distribution system. In some implementations, the central asset management system  1004  may additionally or alternatively communicate with the plurality of luminaires  1006  via other types of networks or channels, such as one or more wired and/or wireless communications networks  1013 . In the illustrated implementation, the luminaires  1006  may wirelessly communicate with an access point  1017  (e.g., cellular tower, WIFI® access point) operatively coupled to the one or more communication networks  1013 . 
     As shown in  FIG. 12 , each luminaire  1006  includes one or more light sources  1010 , a power-line transceiver  1012  (or other wired/wireless transceiver(s)), a power supply  1014 , a local illumination control system (ICS)  1015 , a luminaire processor  1016 , a nontransitory data store  1018 , and one or more wired/wireless short-range communications transceivers  1020  (e.g., Bluetooth®, Wi-Fi®, USW). 
     The transceivers  1012  or  1020  provide wired and/or wireless communications capabilities which allow the luminaires  1006  to be communicatively coupled with the central asset management system  1004  and one or more mobile control systems  1022 . For example, in some instances the central asset management system may be implemented as a supervisory control and data acquisition (SCADA) system. In these instances, the transceiver(s)  1012  may include a SCADA transceiver that facilitates wireless communication and/or wired communication, such as communication over a power-line communication system. 
     The mobile control systems  1022  may include accurate location identification systems, such as global positioning system (GPS) receivers  1024  ( FIG. 12 ) that communicate with GPS satellites  1026  ( FIG. 10 ). The mobile control systems  1022  may also include one or more short-range wired or wireless communications capabilities, such as one or more of Bluetooth®, WiFi®, near field communication (NFC), ANT®, IEEE 802.15 (e.g., ZigBee), or USB®. 
     During installation, testing or setup of a luminaire  1006 , the mobile control system  1022  positioned proximate the luminaire may transmit its location information (e.g., geographical coordinates) to the luminaire over a data communications channel (e.g., Bluetooth®, Wi-Fi®, USW). Since the location information is near the luminaire  1006  when the location information is determined, the luminaire may store the received location information as the luminaire&#39;s location in the data store  1018 , for example. In some implementations, the luminaire may be equipped with a GPS receiver which may be used to obtain the time of day and location of the luminaire. In this regard, each of the installed luminaires “knows” its own geographical location. 
     In some implementations, each of the luminaires  1006  is programmed with a unique identifier (e.g., identification number, such as a serial number). The unique identifier uniquely identifies the respective luminaire with respect to all other luminaires in an installation, or installed base, asset collection, or inventory of an entity. The unique identifier may be programmed or otherwise stored in the nontransitory data store  1018  during manufacture, during installation, or at any other time. The unique identifier may be programmed using one of the mobile control systems  1022 , a factory programming fixture, DIP switches, or using any other suitable method. 
     Once the luminaires  1006  have received their respective identification information and location information, the luminaires may send such information to the central asset management system  1004  for storage thereby. The central asset management system  1004  may also include mapping functions that generate an asset management map ( FIG. 9 ) which may visually present luminaire information to one or more users. The central asset management system  1004  may also analyze the collected data and generate one or more electronic reports that are valuable for users associated with the illumination system  1000 . 
     The local ICS  1015  may include a photocontrol that has a photosensitive transducer (photosensor) associated therewith. The ICS  1015  may be operative to control operation of the light sources  1010  based on ambient light levels detected by the photosensor. The ICS  1015  may be coupled to the processor  1016  and operative to provide illumination data signals to the processor so that the processor may control the light sources  1010  based on the received illumination data signals. The ICS  1015  may also be configured as a switch that provides electrical power to the light sources  1010  only when detected light levels are below a desired level. For example, the local ICS  1015  of the luminaire  1006  may include a photosensor that controls an electro-mechanical relay coupled between a source of electrical power and a control device (e.g., a magnetic or electronic transformer) within the luminaire. The electro-mechanical relay may be configured to be in an electrically continuous state unless a signal from the photosensor is present to supply power to the luminaire  1006 . If the photosensor is illuminated with a sufficient amount of light, the photosensor outputs the signal that causes the electro-mechanical relay to switch to an electrically discontinuous state such that no power is supplied to the luminaire  1006 . 
     In some implementations, the ICS  1015  may include one or more clocks or timers, and/or one or more look-up tables or other data structures that indicate dawn events and dusk events for one or more geographical locations at various times during a year. The time of occurrence of various solar events may additionally or alternatively be calculated using geolocation, time, or date data either generated by or stored within a nontransitory processor-readable medium of the luminaire  1006  or obtained from one or more external devices via one or more wired or wireless communication interfaces either in or communicably coupled to the luminaire. In some implementations, the ICS  1015  is implemented partially or fully by the processor  1016 . 
     The power line transceiver  1012  and the power supply  1014  of the luminaire  1006  may each be electrically coupled with the power distribution system  1002  ( FIG. 10 ). The power line transceiver  1012  may transmit and receive power line control or data signals over the power distribution system  1002 , and the power supply  1014  may receive a power signal from the power distribution system. The power line transceiver  1012  may separate or decode the power line control or data signals from the power signals and may provide the decoded signals to the luminaire processor  1016 . In turn, the luminaire processor  1016  may generate one or more light source control commands that are supplied to the light sources  1010  to control the operation thereof. The power line transceiver  1012  may also encode power line control or data signals and transmit the signals to the central asset management system  1004  via the power distribution system  1002 . 
     The power supply  1014  may receive an AC power signal from the power distribution system  1002 , generate a DC power output, and supply the generated DC power output to the light sources  1010  to power the light sources as controlled by light source control commands from the luminaire processor  1016 . 
     The light sources  1010  may include one or more of a variety of conventional light sources, for example, incandescent lamps or fluorescent lamps such as high-intensity discharge (HID) lamps (e.g., mercury vapor lamps, high-pressure sodium lamps, metal halide lamps). The light sources  1010  may also include one or more solid-state light sources (e.g., light emitting diodes (LEDs), organic LEDs (OLEDs), polymer LEDs (PLEDs)). 
     The central asset management system  1004  may receive luminaire information from each of the luminaires  1006  in the illumination system  1000 . For example, in some implementations the central asset management system  1004  may interrogate the luminaires  1006  (e.g., via the power distribution system  1002 ) and receive signals from each of the luminaires that provide luminaire information. In some implementations, the luminaires  1006  may automatically send luminaire information to the central asset management system without interrogation. 
     The central asset management system  1004  may store the luminaire information in one or more nontransitory computer- or processor-readable media. The luminaire information may include, for example, identification information, location information, installation date, illumination patterns, installation cost, installation details, type of luminaire, maintenance activities, specifications, purchase date, cost, expected lifetime, warranty information, service contracts, service history, spare parts, comments, or anything other information that may be useful to users (e.g., management, analysts, purchasers, installers, maintenance workers). 
     In some implementations, data communicated between the central asset management system  1004  and the luminaires  1006  may be converted into power line control signals that may be superimposed onto wiring of the power distribution system  1002  so that the signals are transmitted or distributed via the power distribution system. In some implementations, the power line signals may be in the form of amplitude modulation signals, frequency modulation signals, frequency shift keyed signals (FSK), differential frequency shift keyed signals (DFSK), differential phase shift keyed signals (DPSK), or other types of signals. The command code format of the power line signals may be that of a commercially available controller format or may be that of a custom controller format. 
     An example power line communication system is the TWACS® system available from Aclara Corporation, Hazelwood, Mo. 
     The central asset management system  1004  may utilize a power line transceiver or interface  1158  (see  FIG. 11 ) that includes special coupling capacitors to connect transmitters to power-frequency AC conductors of the power distribution system  1002 . Signals may be impressed on one conductor, on two conductors or on all three conductors of a high-voltage AC transmission line. Filtering devices may be applied at substations of the power distribution system  1002  to prevent the carrier frequency current from being bypassed through substation infrastructure. Power line carrier systems may be favored by utilities because they allow utilities to reliably move data over an infrastructure that they control. 
     In some instances, the power line signals may be in the form of a broadcast signal or command delivered to each of the luminaires  1006  in the illumination system  1000 . In some instances, the power line signals may be specifically addressed to an individual luminaire  1006 , or to one or more groups or subsets of luminaires. 
       FIGS. 11 and 12  and the following discussion provide a brief, general description of the components forming the illustrative illumination system  1000  including the central asset management system  1004 , the power distribution system  1002 , the mobile control systems  1022 , and the luminaires  1006  in which the various illustrated implementations can be implemented. Although not required, some portion of the implementations will be described in the general context of computer-executable instructions or logic and/or data, such as program application modules, objects, or macros being executed by a computer. Those skilled in the relevant art will appreciate that the illustrated implementations as well as other implementations can be practiced with other computer system or processor-based device configurations, including handheld devices, for instance Web enabled cellular phones or PDAs, multiprocessor systems, microprocessor-based or programmable consumer electronics, personal computers (“PCs”), network PCs, minicomputers, mainframe computers, and the like. The implementations can be practiced in distributed computing environments where tasks or modules are performed by remote processing devices, which are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices. 
     The central asset management system  1004  may take the form of a PC, server, or other computing system executing logic or other machine executable instructions. The central asset management system  1004  includes one or more processors  1106 , a system memory  1108  and a system bus  1110  that couples various system components including the system memory  1108  to the processor  1106 . The central asset management system  1004  will at times be referred to in the singular herein, but this is not intended to limit the implementations to a single system, since in certain implementations, there will be more than one central asset management system  1004  or other networked computing device involved. Non-limiting examples of commercially available systems include, but are not limited to, an 80×86 or Pentium series microprocessor from Intel Corporation, U.S.A., a PowerPC microprocessor from IBM, a Sparc microprocessor from Sun Microsystems, Inc., a PA-RISC series microprocessor from Hewlett-Packard Company, or a 68xxx series microprocessor from Motorola Corporation. 
     The central asset management system  1004  may be implemented as a SCADA system or as one or more components thereof. Generally, a SCADA system is a system operating with coded signals over communication channels to provide control of remote equipment. The supervisory system may be combined with a data acquisition system by adding the use of coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions. 
     The processor  1106  may be any logic processing unit, such as one or more central processing units (CPUs), microprocessors, digital signal processors (DSPs), graphics processors (GPUs), application-specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), etc. Unless described otherwise, the construction and operation of the various blocks shown in  FIGS. 11 and 12  are of conventional design. As a result, such blocks need not be described in further detail herein, as they will be understood by those skilled in the relevant art. 
     The system bus  1110  can employ any known bus structures or architectures. The system memory  1108  includes read-only memory (“ROM”)  1112  and random access memory (“RAM”)  1114 . A basic input/output system (“BIOS”)  1116 , which may be incorporated into at least a portion of the ROM  1112 , contains basic routines that help transfer information between elements within the central asset management system  1004 , such as during start-up. Some implementations may employ separate buses for data, instructions and power. 
     The central asset management system  1004  also may include one or more drives  1118  for reading from and writing to one or more nontransitory computer- or processor-readable media  1120  (e.g., hard disk, magnetic disk, optical disk). The drive  1118  may communicate with the processor  1106  via the system bus  1110 . The drive  1118  may include interfaces or controllers (not shown) coupled between such drives and the system bus  1110 , as is known by those skilled in the art. The drives  1118  and their associated nontransitory computer- or processor-readable media  1120  provide nonvolatile storage of computer-readable instructions, data structures, program modules and other data for the central asset management system  1004 . Those skilled in the relevant art will appreciate that other types of computer-readable media may be employed to store data accessible by a computer. 
     Program modules can be stored in the system memory  1108 , such as an operating system  1130 , one or more application programs  1132 , other programs or modules  1134 , and program data  1138 . 
     The application program(s)  1132  may include logic capable of providing the luminaire management functionality described herein. For example, applications programs  1132  may include programs to analyze and organize luminaire information automatically received from the luminaires  1006 . The application programs  1132  may also include programs to present raw or analyzed illumination information in a format suitable for presentation to a user. 
     The system memory  1108  may include communications programs  1140  that permit the central asset management system  1004  to access and exchange data with other networked systems or components, such as the luminaires  1006 , the mobile control systems  1022 , and/or other computing devices. 
     While shown in  FIG. 11  as being stored in the system memory  1108 , the operating system  1130 , application programs  1132 , other programs/modules  1134 , program data  1138  and communications  1140  can be stored on the nontransitory computer- or processor-readable media  1120  or other nontransitory computer- or processor-readable media. 
     Personnel can enter commands (e.g., system maintenance, upgrades) and information (e.g., parameters) into the central asset management system  1004  using one or more communicably coupled input devices  1146  such as a touch screen or keyboard, a pointing device such as a mouse, and/or a push button. Other input devices can include a microphone, joystick, game pad, tablet, scanner, biometric scanning device, etc. These and other input devices may be connected to the processor  1106  through an interface such as a universal serial bus (“USB”) interface that couples to the system bus  1110 , although other interfaces such as a parallel port, a game port or a wireless interface or a serial port may be used. One or more output devices  1150 , such as a monitor or other display device, may be coupled to the system bus  1110  via a video interface, such as a video adapter. In at least some instances, the input devices  1146  and the output devices  1150  may be located proximate the central asset management system  1004 , for example when the system is installed at the system user&#39;s premises. In other instances, the input devices  1146  and the output devices  1150  may be located remote from the central asset management system  1004 , for example, when the system is installed on the premises of a service provider. 
     In some implementations, the central asset management system  1004  uses one or more of the logical connections to optionally communicate with one or more luminaires  1006 , remote computers, servers and/or other devices via one or more communications channels, for example, the one or more networks  1013 . These logical connections may facilitate any known method of permitting computers to communicate, such as through one or more LANs and/or WANs. Such networking environments are known in wired and wireless enterprise-wide computer networks, intranets, extranets, and the Internet. 
     In some implementations, a network port or interface  1156 , communicatively linked to the system bus  1110 , may be used for establishing and maintaining communications over the communications network  1013 . 
     The central asset management system  1004  may include a power line transceiver or interface  1158  and an AC/DC power supply  1160  that are each electrically coupled to the power distribution system  1002 . The AC/DC power supply  1160  converts AC power from the power distribution system  1002  into DC power, which may be provided to power the various components of the central asset management system  1004 . As discussed above, the power line interface  1158  may be operative to superimpose control signals onto one or more conductors of the power distribution system  1002  that carries power to the luminaires  1006 . The power line interface  1158  may also be operative to decode and receive communication signals sent over the power distribution system  1002  (e.g., from the power line interface  1012  of a luminaire  1006  ( FIG. 10 )). 
     In some implementations, the central asset management system  1004  may utilize the one or more wired and/or wireless communications networks  1013  to communicate with the luminaires  1006  instead of or in addition to communicating through the power distribution system  1002 . 
     In the illumination system  1000 , program modules, application programs, or data, or portions thereof, can be stored in one or more computing systems. Those skilled in the relevant art will recognize that the network connections shown in  FIG. 11  are only some examples of ways of establishing communications between computers, and other connections may be used, including wireless. In some implementations, program modules, application programs, or data, or portions thereof, can even be stored in other computer systems or other devices (not shown). 
     For convenience, the processor  1106 , system memory  1108 , network port  1156  and devices  1146 ,  1150  are illustrated as communicatively coupled to each other via the system bus  1110 , thereby providing connectivity between the above-described components. In alternative implementations, the above-described components may be communicatively coupled in a different manner than illustrated in  FIG. 11 . For example, one or more of the above-described components may be directly coupled to other components, or may be coupled to each other, via intermediary components (not shown). In some implementations, system bus  1110  is omitted and the components are coupled directly to each other using suitable connections. 
     It should be appreciated that the luminaires  1006  may include components similar to those components present in the central asset management system  1004 , including the processor  1106 , power supply  1160 , power line interface  1158 , buses, nontransitory computer- or processor-readable media, wired or wireless communications interfaces, and one or more input and/or output devices. 
     The mobile control system  1022  can include any device, system or combination of systems and devices having at least wired or wireless communications capabilities. In most instances, the mobile control system  1022  includes additional devices, systems, or combinations of systems and devices capable of providing graphical data display capabilities. Examples of such mobile control systems  1022  can include without limitation, cellular telephones, smart phones, tablet computers, desktop computers, laptop computers, ultraportable or netbook computers, personal digital assistants, handheld devices, other smart appliances, and the like. 
     In other implementations, the luminaire includes a satellite positioning receiver such as GPS receiver, Glonass, etc., and stores its position data in nontransitory computer- or processor-readable media or memory. The position data may only need to be acquired relatively infrequently, thus enabling location data to be acquired in poor reception areas or with relatively low cost receiver hardware. 
     The mobile control system  1022  may include one or more processors  1182  and nontransitory computer- or processor-readable media or memory, for instance one or more data stores  1184  that may include nonvolatile memories such as read only memory (ROM) or FLASH memory and/or one or more volatile memories such as random access memory (RAM). 
     The mobile control system  1022  may include one or more transceivers or radios and associated antennas. For example, the mobile control system  1022  may include one or more cellular transceivers or radios  1188  and one or more short-range transceivers or radios  1190 , such as WIFI® transceivers or radios, BLUETOOTH® transceivers or radios, along with associated antennas. The mobile control system  1022  may further include one or more wired interfaces (not shown) that utilize parallel cables, serial cables, or wireless channels capable of high speed communications, for instance, via one or more of FireWire®, Universal Serial Bus® (USB), Thunderbolt®, or Gigabit Ethernet®, for example. 
     The mobile control system  1022  may include a user input/output subsystem, for example including a touchscreen or touch sensitive display device  1192 A and one or more speakers  1192 B. The touchscreen or touch sensitive display device  1192 A may include any type of touchscreen including, but not limited to, a resistive touchscreen or a capacitive touchscreen. The touchscreen or touch sensitive display device  1192 A may present a graphical user interface, for example in the form of a number of distinct screens or windows, which include prompts and/or fields for selection. The touchscreen or touch sensitive display device  1192 A may present or display individual icons and controls, for example virtual buttons or slider controls and virtual keyboard or key pads which are used to communicate instructions, commands, and/or data. While not illustrated, the user interface may additionally or alternatively include one or more additional input or output devices, for example an alphanumeric keypad, a QWERTY keyboard, a joystick, scroll wheel, touchpad or similar physical or virtual input device. 
     In some implementations, the touchscreen  1192 A or other input component may include simple adjustment “sliders” to set the current to individual LED arrays. More sophisticated graphical user interfaces (GUIs) may also be used, for example, buttons for selecting NEMA Type 1, NEMA Type 2, or other illumination pattern standards, scheduled dimming selection and other features. The LED driver channel current, dimming schedule, GPS coordinates and other data may be transmitted wirelessly to the luminaire, where such data are stored (e.g., in the data store  1184 ). 
     The mobile control system  1022  may include one or more image capture devices  1194 , for example, cameras with suitable lenses, and optionally one or more flash or lights for illuminating a field of view to capture images. The image capture device(s)  1194  may capture still digital images or moving or video digital images. Image information may be stored as files via the data store  1184 , for example. 
     Some or all of the components within the mobile control system  1022  may be communicably coupled using at least one bus (not shown) or similar structure adapted to transferring, transporting, or conveying data between the devices, systems, or components used within the mobile control system  1022 . The bus can include one or more serial communications links or a parallel communications link such as an 8-bit, 16-bit, 32-bit, or 64-bit data bus. In some implementations, a redundant bus (not shown) may be present to provide failover capability in the event of a failure or disruption of a primary bus. 
     The processor(s)  1182  may include any type of processor (e.g., ARM Cortext-A8, ARM Cortext-A9, Snapdragon 600, Snapdragon 800, NVidia Tegra 4, NVidia Tegra 4i, Intel Atom Z2580, Samsung Exynos 5 Octa, Apple A7, Motorola X8) adapted to execute one or more machine executable instruction sets, for example a conventional microprocessor, a reduced instruction set computer (RISC) based processor, an application specific integrated circuit (ASIC), digital signal processor (DSP), or similar. Within the processor(s)  1182 , a non-volatile memory may store all or a portion of a basic input/output system (BIOS), boot sequence, firmware, startup routine, and communications device operating system (e.g., iOS®, Android®, Windows® Phone, Windows® 8, and similar) executed by the processor  1182  upon initial application of power. The processor(s)  1182  may also execute one or more sets of logic or one or more machine executable instruction sets loaded from volatile memory subsequent to the initial application of power to the processor  1182 . The processor  1182  may also include a system clock, a calendar, or similar time measurement devices. One or more geolocation devices, for example a Global Positioning System (GPS) receiver  1024  may be communicably coupled to the processor  1182  to provide additional functionality such as geolocation data to the processor  1182 . 
     The transceivers or radios  1188 ,  1190  can include any device capable of transmitting and receiving communications via electromagnetic energy. 
     Non-limiting examples of cellular communications transceivers or radios  1188  include a CDMA transceiver, a GSM transceiver, a 3G transceiver, a 4G transceiver, an LTE transceiver, and any similar current or future developed computing device transceiver having at least one of a voice telephony capability or a data exchange capability. In at least some instances, the cellular transceivers or radios  1188  can include more than one interface. For example, in some instances, the cellular transceivers or radios  1188  can include at least one dedicated, full- or half-duplex, voice call interface and at least one dedicated data interface. In other instances, the cellular transceivers or radios  1188  can include at least one integrated interface capable of contemporaneously accommodating both full- or half-duplex voice calls and data transfer. 
     Non-limiting examples of WIFI® short-range transceivers or radios  1190  include various chipsets available from Broadcom, including BCM43142, BCM4313, BCM94312MC, BCM4312, and chipsets available from Atmel, Marvell, or Redpine. Non-limiting examples of Bluetooth® short-range transceivers or radios  1188  include various chipsets available from Nordic Semiconductor, Texas Instruments, Cambridge Silicon Radio, Broadcom, and EM Microelectronic. 
     As noted, the data store  1184  can include non-volatile storage memory and in some implementations may include volatile memory as well. At least a portion of the data store  1184  may be used to store one or more processor executable instruction sets for execution by the processor  1182 . In some implementations, all or a portion of the memory may be disposed within the processor  1182 , for example in the form of a cache. In some implementations, the memory may be supplemented with one or more slots configured to accept the insertion of one or more removable memory devices such as a secure digital (SD) card, a compact flash (CF) card, a universal serial bus (USB) memory “stick,” or the like. 
     In at least some implementations, one or more sets of logic or machine executable instructions providing applications or “apps” executable by the processor  1182  may be stored in whole or in part in at least a portion of the memory  1184 . In at least some instances, the applications may be downloaded or otherwise acquired by the end user, for example using an online marketplace such as the Apple App Store, Amazon Marketplace, or Google Play marketplaces. In some implementations, such applications may start up in response to selection of a corresponding user selectable icon by the user or consumer. The application can facilitate establishing a data link between the mobile control system  1022  and the central asset management system  1004  or the luminaires  1006  via the transceivers or radios  1188 ,  1190  and communication networks  1013 . 
       FIG. 13  is a flow diagram showing a method  1300  of operation of a processor-based device to provide installed luminaires in an illumination system with illumination pattern information. The method  1300  starts at  1302 . For example, the method  1300  may start in response to commissioning an illumination system, such as the illumination system  1000  shown in  FIG. 10 . The method  1300  may also start in response to a need to modify an illumination pattern of a luminaire after installation. 
     At  1304 , a luminaire is provided that includes a housing having a circuit board mounting area. The luminaire also includes at least one circuit board physically coupled to the circuit board mounting area. A number N of solid-state light emitter arrays are carried on the at least one circuit board. Each of the N solid-state light emitter arrays includes a plurality of solid-state light emitters. As discussed above, at least some of the plurality of solid-state light emitters of one of the N solid-state light emitter arrays positioned at a different angle from at least some of the solid-state light emitters of at least one of the other N solid-state light emitter arrays. The luminaire also includes a solid-state light emitter driver including N independently controllable driver channels, at least one luminaire processor operatively coupled to the solid-state light emitter driver to control the operation thereof and at least one luminaire transceiver operatively coupled to the at least one luminaire processor and to at least one data communications channel. The luminaire further includes at least one luminaire nontransitory processor-readable storage medium operatively coupled to the at least one luminaire processor. 
     At  1306 , the luminaire receives, by the at least one luminaire transceiver, illumination pattern information from a remotely located external processor-based system over the at least one data communications channel. As noted above, the illumination pattern information is indicative of an illumination pattern to be produced by the N solid-state light emitter arrays. As an example, the luminaire may receive the illumination pattern information over a power line distribution system (e.g., PLC). The luminaire may also receive the luminaire pattern information wirelessly from a mobile control system positioned proximate to the luminaire. Examples of mobile control systems can include without limitation, cellular telephones, smart phones, tablet computers, desktop computers, laptop computers, ultraportable or netbook computers, personal digital assistants, handheld devices, other smart appliances, and the like. For instance, an installer or technician may stand near an installed luminaire with a mobile control system during installation, testing, modification or setup of the luminaire. As noted above, the mobile control system includes illumination pattern information that may be provided to the luminaire. In some implementations, the mobile control system may include an interface that allows a user to manually input illumination pattern information (e.g., NEMA Type beam pattern, custom beam angles, custom beam shapes) into the mobile control system. 
     At  1308 , the luminaire may store the received illumination pattern information on the at least one nontransitory processor-readable storage medium. At  1310 , the luminaire may control the operation of the solid-state light emitter driver based at least in part on the illumination pattern information. 
     The method  1300  ends at  1312  until started or invoked again. For example, the method  1300  may be performed for each luminaire in an illumination system during setup of the luminaire or when an illumination pattern for the luminaire is to be modified. The method  1300  may also be repeated for a luminaire after certain events, such as a maintenance event or a relocation event.
