No. 60/954,007 filed on 5 Aug. 2007 and to U.S. Provisional Application Ser. No. 61/033,838 filed on 5 Mar. 2008, all of which are incorporated herein by reference.


BACKGROUND
This application relates to controlling a scene utilizing self-energizing switches.
Switches that transmit wireless communications are known. For example, some switches transmit wireless communications to garage door openers. Many switches utilize a replaceable internal power source, such as a battery, to power the wireless communication transmissions. Servicing these internal power sources can be inconvenient and costly. For example, accessing a battery within a wall-mounted light switch is often difficult and time-consuming. Rather than replaceable internal power sources, some switches harvest energy to power the wireless communications from the switch.
Some buildings include complex control systems for lighting, audio equipment, etc. Prior control systems include wired and battery based switches, both of which are often expensive and inflexible.
SUMMARY
An example lighting control arrangement includes a power supply, a first load operative to receive power when coupled to the power supply, and a second load operative to receive power when coupled to the power supply. A receiver is programmable to couple the first load, the second load, or both to the power supply in response to a wireless signal. A switch includes a wireless transmitter portion powered by a self-energizing portion. A wireless transmitter portion communicates the wireless signal to the receiver in response to an actuation of the switch.
Another example lighting control arrangement includes a power supply, a first light operative to illuminate when coupled to the power supply, and a second light operative to illuminate when coupled to the power supply. A programmable controller is configured to store at least one scene. A receiver is operative to couple the first light, the second light, or both to the power supply in response to a wireless signal and based on the scene. A switch has a wireless transmitter portion powered by a self-energizing portion. The wireless transmitter portion communicates the wireless signal to the receiver in response to an actuation of the switch.
An example method for use with the wireless security system includes programming a controller to store at least one light scene and communicating a wireless signal using power provided by a self-energizing portion of a switch. The method includes initiating one of the scenes in response to the communicated wireless signal.
These and other features of the present invention can be best understood from the following specification and drawings, the following of which is a brief description.

DETAILED DESCRIPTION
Referring to FIG. 1, an example control arrangement 10 includes a switch 14 in wireless communication with a receiver 18. A power supply 22 is operative to provide power to a first light 26a, a second light 26b, and a third light 26c. The receiver 18 selectively couples the power supply 22 to one or more of the lights 26a-26c in response to a wireless communication 30 from the switch 14.
In this example, the switch 14 is self-energizing and includes a wireless transmitter portion 34 and a self-energizing portion 38. The self-energizing portion 38 provides power to the wireless transmitter portion 34, which transmits the wireless communication 30. One example switch 14 suitable for transmitting the wireless communication 30 is available from EnOcean under Product No. PTM250.
The example switch 14 is a rocker type switch and is actuated by rocking portions of the switch 14 within a switch housing 50. Other example switch actuations include motion sensors indicating the presence of a user's hand, for example, or push button type switches. In one example, the actuation of portions of the switch 14 energizes the self-energizing portions 38 of the switch 14. In other examples, the self-energizing portion 38 energizes through photovoltaic cells, piezoelectric devices, etc. The example switch 14 thus does not rely on an internal power supply to power the wireless communication 30, but instead harvests energy to power the wireless communication 30.
Although the receiver 18 is shown as a multi-channel receiver, it should be understood that the receiver 18 could also be a single channel receiver. Other examples include the receiver 18 coupled different numbers of the lights 26a-26c. 
Other examples of the control arrangement 10 utilize more than one of the receiver 18. One example receiver 18 suitable for use within the control arrangement 10 is available from EnOcean under Product No. RCM130C. Although the location of the receiver 18 is fixed in this example, other example receivers are portable. For example, other examples of the receiver 18 include a USB portion and are operative to receive the wireless communication 30 once the USB portion is linked to a computer (not shown). Such examples facilitate moving the receiver 18 to receive the wireless communication 30 in a multiple of areas.
The example receiver 18 includes a programmable controller 46 that controls the illumination levels of the lights 26a-26c by controlling the coupling between the power supply 22 and each of the lights 26a-26c, the power level supplied to the lights 26a-26c from the power supply 22, or both. A person skilled in the art having the benefit of this disclosure would be able to develop a controller suitable for providing such control over the illumination of the lights 26a-26c. Example programmable controllers 46, which may also reside in switch housing 50, include a microprocessor, a lap top computer, etc.
The first light 26a, the second light 26b, and the third light 26c provide a scene 42, which is a lighting scene in this example. In this example of the scene 42, the first light 26a is more illuminated than both the second light 26b and the third light 26c, and the second light 26b is more illuminated than the third light 26c. Also in this example, the third light 26c is off. That is, the third light 26c provides no illumination in this example scene 42. Other examples of the scene 42 incorporate a piece of audiovisual equipment, such as a stereo, or a computer.
Referring now to FIG. 2 with continuing reference to FIG. 1, an example control arrangement 110 that is somewhat similar to the control arrangement 10 described in the FIG. 1 example is implemented within a building 58. In this disclosure, like reference numerals designate like elements where appropriate and reference numerals with the addition of 100 or multiples thereof designate modified elements. The modified elements incorporate the same basic features and benefits of the corresponding modified elements, except where stated otherwise.
In this example, the control arrangement 110 includes four lights 126a-126d and two receivers 118a and 118b. A user 66 actuates a switch 114, which then communicates a wireless signal 130 to both the receiver 118a and the receiver 118b. The receivers 118a, 118b are programmed such that, upon receipt of the wireless signal 130, the receivers 118a, 118b couple the light 126a and the light 126d to a power supply (not shown). The building includes a plurality of rooms 62a-62d. Powering the light 126a illuminates the room 62a and powering the light 126d illuminates the room 62d. Thus, in this example, the scene 142 for the building 58 illuminates the rooms 62a and 62d, not rooms 62b and 62c. Other examples include using the control arrangement 110 to control power distribution to a stereo 60 within the room 62a, which is a portion of the scene 142. Still other examples include providing power to a computer 61, a television 63 a ceiling fan 64, or a power receptacle 65.
Referring now to FIG. 3 with continuing reference to FIG. 1, the user 66 actuates a switch 214 to communicate a wireless signal 230 to the receiver 218, which is mounted on the exterior of a home 70. The receiver 218, through wired connections (not shown), is programmed to illuminate initiate a scene 242 in response to the wireless signal 230. In this example, the lighting scene 242 comprises illuminating a first plurality of lights 226a-226c, but not a second plurality of lights 226d-226g. In this example, the lights 126a, 126b illuminate an exterior area 74, and the light 126c illuminates an interior area 78 of the home 70. In so doing, the user 66 is able to remotely initiate a lighting scene 242 associated with the home 70 using the switch 214.
Features of this disclosure include utilizing self-energizing switches to control a particular lighting scene, which can be changed by programming a controller. Another feature of this disclosure is that the switch is movable relative to the receiver and does not require a wired connection to power wireless communications from the switch.
Although a preferred embodiment of this invention has been disclosed, a worker of ordinary skill in this art would recognize that certain modifications would come within the scope of this invention. For that reason, the following claims should be studied to determine the true scope and content of this invention.
