A statement herein that two components in a device are “directly electrically connected,” means that there are no components electrically between the components, the insertion of which materially affect the function or functions provided by the device. For example, two components can be referred to as being electrically connected, even though they may have a small resistor between them which does not materially affect the function or functions provided by the device (indeed, a wire connecting two components can be thought of as a small resistor); likewise, two components can be referred to as being electrically connected, even though they may have an additional electrical component between them which allows the device to perform an additional function, while not materially affecting the function or functions provided by a device which is identical except for not including the additional component; similarly, two components which are directly connected to each other, or which are directly connected to opposite ends of a wire or a trace on a circuit board, are electrically connected. A statement herein that two components in a device are “switchably electrically connected” means that there is a switch located between the two components, the switch being selectively closed or opened, wherein if the switch is closed, the two components are directly electrically connected, and if the switch is open (i.e., during any time period that the switch is open), the two components are not electrically connected. The expression “illumination” (or “illuminated”), as used herein when referring to a solid state light emitter, means that at least some current is being supplied to the solid state light emitter to cause the solid state light emitter to emit at least some light. The expression “illuminated” encompasses situations where the solid state light emitter emits light continuously or intermittently at a rate such that a human eye would perceive it as emitting light continuously, or where a plurality of solid state light emitters of the same color or different colors are emitting light intermittently and/or alternatingly (with or without overlap in “on” times) in such a way that a human eye would perceive them as emitting light continuously (and, in cases where different colors are emitted, as a mixture of those colors). The expression “excited”, as used herein when referring to a lumiphor, means that at least some electromagnetic radiation (e.g., visible light, UV light or infrared light) is contacting the lumiphor, causing the lumiphor to emit at least some light. The expression “excited” encompasses situations where the lumiphor emits light continuously or intermittently at a rate such that a human eye would perceive it as emitting light continuously, or where a plurality of lumiphors of the same color or different colors are emitting light intermittently and/or alternatingly (with or without overlap in “on” times) in such a way that a human eye would perceive them as emitting light continuously (and, in cases where different colors are emitted, as a mixture of those colors). The expression “lighting device” as used herein is not limited, except that it is capable of emitting light. That is, a lighting device can be a device which illuminates an area or volume (e.g., a room, a swimming pool, a warehouse, an indicator, a road, a vehicle, a road sign, a billboard, a ship, a boat, an aircraft, a stadium, a tree, a window, a yard, etc.), an indicator light, or a device or array of devices that illuminate an enclosure, or a device that is used for edge or back-lighting (e.g., back light poster, signage, LCD displays), or any other light emitting device. Although the terms “first”, “second”, etc. may be used herein to describe various elements, components, regions, layers, sections and/or parameters, these elements, components, regions, layers, sections and/or parameters should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present invention. Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another elements as illustrated in the Figures. Such relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in the Figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The exemplary term “lower”, can therefore, encompass both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The exemplary terms “below” or “beneath” can, therefore, encompass both an orientation of above and below. Embodiments in accordance with the present invention are described herein with reference to cross-sectional (and/or plan view) illustrations that are schematic illustrations of idealized embodiments of the present invention. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the present invention should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a molded region illustrated or described as a rectangle will, typically, have rounded or curved features. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region of a device and are not intended to limit the scope of the present invention. Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature. The solid state light emitter (or solid state light emitters) used in the devices according to the present invention, and the lumiphor (or lumiphors) used in the devices according to the present invention, can be selected from among any solid state light emitters and lumiphors known to persons of skill in the art. A variety of solid state light emitters are well-known. For example, one type of solid state light emitter is a light emitting diode. Wide varieties of light emitting diodes and lumiphors are readily obtainable and well known to those of skilled in the art, and any of them can be employed (e.g., AlInGaP for the 600 nm to 630 nm light emitting diodes). Examples of types of such light emitting diodes include inorganic and organic light emitting diodes, a variety of each of which are well-known in the art. Representative examples of suitable LEDs for use in the present invention are described in: (1) U.S. Patent Application No. 60/753,138, filed on Dec. 22, 2005, entitled “Lighting Device” (inventor: Gerald H.

Negley; attorney docket number 931—027 PRO, the entirety of which is hereby incorporated by reference; and (8) U.S. Patent Application No. 60/851,230, filed on Oct. 12, 2006, entitled “LIGHTING DEVICE AND METHOD OF MAKING SAME” (inventor: Gerald H. Negley; attorney docket number 931—041 PRO, the entirety of which is hereby incorporated by reference. The one or more luminescent materials can be any desired luminescent material. The one or more luminescent materials can be down-converting or up-converting, or can include a combination of both types. For example, the one or more luminescent materials can be selected from among phosphors, scintillators, day glow tapes, inks which glow in the visible spectrum upon illumination with ultraviolet light, etc. The one or more luminescent materials can be provided in any desired form. For example, the luminescent element can be embedded in a resin (i.e., a polymeric matrix), such as a silicone material, an epoxy material, a glass material or a metal oxide material. The one or more lumiphors can individually be any lumiphor, a wide variety of which, as noted above, are known to those skilled in the art. For example, the (or each of the) one or more lumiphors can comprise (or can consist essentially of, or can consist of) one or more phosphor. The (or each of the) one or more lumiphors can, if desired, further comprise (or consist essentially of, or consist of) one or more highly transmissive (e.g., transparent or substantially transparent, or somewhat diffuse) binder, e.g., made of epoxy, silicone, glass, metal oxide or any other suitable material (for example, in any given lumiphor comprising one or more binder, one or more phosphor can be dispersed within the one or more binder). For example, the thicker the lumiphor, in general, the lower the weight percentage of the phosphor can be. Representative examples of the weight percentage of phosphor include from about 3.3 weight percent to about 4.7 weight percent, although, as indicated above, depending on the overall thickness of the lumiphor, the weight percentage of the phosphor could be generally any value, e.g., from 0.1 weight percent to 100 weight percent (e.g., a lumiphor formed by subjecting pure phosphor to a hot isostatic pressing procedure). In some situations, a weight percentage of about 20 weight percent is advantageous. The present invention is further directed to lighting devices as described herein, wherein mixed light exiting the lighting device is in the proximity of light on the blackbody locus having color temperature of 2700 K, 3000 K or 3500 K, namely: mixed light having x, y color coordinates which define a point which is within an area on a 1931 CIE Chromaticity Diagram enclosed by first, second, third, fourth and fifth line segments, the first line segment connecting a first point to a second point, the second line segment connecting the second point to a third point, the third line segment connecting the third point to a fourth point, the fourth line segment connecting the fourth point to a fifth point, and the fifth line segment connecting the fifth point to the first point, the first point having x, y coordinates of 0.4578, 0.4101, the second point having x, y coordinates of 0.4813, 0.4319, the third point having x, y coordinates of 0.4562, 0.4260, the fourth point having x, y coordinates of 0.4373, 0.3893, and the fifth point having x, y coordinates of 0.4593, 0.3944 (i.e., proximate to 2700 K); or mixed light having x, y color coordinates which define a point which is within an area on a 1931 CIE Chromaticity Diagram enclosed by first, second, third, fourth and fifth line segments, the first line segment connecting a first point to a second point, the second line segment connecting the second point to a third point, the third line segment connecting the third point to a fourth point, the fourth line segment connecting the fourth point to a fifth point, and the fifth line segment connecting the fifth point to the first point, the first point having x, y coordinates of 0.4338, 0.4030, the second point having x, y coordinates of 0.4562, 0.4260, the third point having x, y coordinates of 0.4299, 0.4165, the fourth point having x, y coordinates of 0.4147, 0.3814, and the fifth point having x, y coordinates of 0.4373, 0.3893 (i.e., proximate to 3000 K); or mixed light having x, y color coordinates which define a point which is within an area on a 1931 CIE Chromaticity Diagram enclosed by first, second, third, fourth and fifth line segments, the first line segment connecting a first point to a second point, the second line segment connecting the second point to a third point, the third line segment connecting the third point to a fourth point, the fourth line segment connecting the fourth point to a fifth point, and the fifth line segment connecting the fifth point to the first point, the first point having x, y coordinates of 0.4073, 0.3930, the second point having x, y coordinates of 0.4299, 0.4165, the third point having x, y coordinates of 0.3996, 0.4015, the fourth point having x, y coordinates of 0.3889, 0.3690, and the fifth point having x, y coordinates of 0.4147, 0.3814 (i.e., proximate to 3500 K). The present invention encompasses devices in which the phosphor particles are as described herein, and in which if the lighting device is supplied with electricity of a first wattage, a mixture of all light exiting from the lighting device which was emitted by the at least one solid state light emitter which emit light having a dominant wavelength which is outside the range of between 600 nm and 700 nm would have x, y color coordinates which define a point which is within an area on a 1931 CIE Chromaticity Diagram enclosed by first, second, third, fourth and fifth line segments, the first line segment connecting a first point to a second point, the second line segment connecting the second point to a third point, the third line segment connecting the third point to a fourth point, the fourth line segment connecting the fourth point to a fifth point, and the fifth line segment connecting the fifth point to the first point, the first point having x, y coordinates of 0.32, 0.40, the second point having x, y coordinates of 0.36, 0.48, the third point having x, y coordinates of 0.43, 0.45, the fourth point having x, y coordinates of 0.42, 0.42, and the fifth point having x, y coordinates of 0.36, 0.38. The present invention further relates to an illuminated enclosure, comprising an enclosed space and at least one lighting device according to the present invention, wherein the lighting device illuminates at least a portion of the enclosure. The present invention further relates to an illuminated surface, comprising a surface and at least one lighting device according to the present invention, wherein the lighting device illuminates at least a portion of the surface. The present invention is further directed to an illuminated area, comprising at least one item selected from among the group consisting of a swimming pool, a room, a warehouse, an indicator, a road, a vehicle, a road sign, a billboard, a ship, a toy, a mirror, a vessel, an electronic device, a boat, an aircraft, a stadium, a computer, a remote audio device, a remote video device, a cell phone, a tree, a window, a yard, a lamppost, an indicator light, or a device or array of devices that illuminate an enclosure, or a device that is used for edge or back-lighting (e.g., back light poster, signage, LCD displays), having mounted therein or thereon at least one lighting device as described herein. In addition, persons of skill in the art are familiar with a wide variety of mounting structures for many different types of lighting, and any such structures can be used according to the present invention. For example, FIG. 4 depicts a lighting device which includes a heat spreading element 11 (formed of a material with good heat conducting properties, e.g., aluminum), insulating regions 12 (which can be applied and/or formed in situ, e.g., by anodizing), a highly reflective surface 13 (which can be applied, e.g., MCPET, marketed by Furukawa of Japan, laminated aluminum or silver) or formed in situ, e.g., by polishing), conductive traces 14, leadframes 15, packaged LEDs 16, a reflective cone 17 and a diffusing element 18. The device depicted in FIG. 4 can further include an insulating element 28 below the conductive traces 14 to avoid unintended contact (e.g., a person receiving a shock) with the conductive traces. The device depicted in FIG. 4 can include any number of packaged LEDs (e.g., up to 50 or 100 or more), and so the heat spreading element 11, as well as the insulating regions 12, reflective surface 13 and insulating element 28 can extend any necessary distance to the right or left, in the orientation shown in FIG. 4, as indicated by the fragmented structures (similarly, the sides of the reflective cone 17 can be located any distance to the right or left). Similarly, the diffusing element 18 can be located any desired distance from the LEDs 16. The diffusing element 18 can be attached to the reflective cone 17, the insulating element 28, the heat spreading element 11, or any other desired structure in any suitable way, persons of skill in the art being familiar with and readily able to provide such attachment in a wide variety of ways. In this embodiment, and other embodiments, the heat spreading element 11 serves to spread out the heat, act as a heat sink, and/or dissipate the heat. Likewise, the reflective cone 17 functions as a heat sink. In addition, the reflective cone 17 can include ridges 19 to enhance its reflective properties. FIG. 5 depicts a representative example of a packaged LED which can be used in the devices according to the present invention. Referring to FIG. 5, there is shown a lighting device 20 comprising a solid state light emitter 21 (in this case, a light emitting diode chip 21), a lead frame 22, a wire 23, an encapsulant region 24, a reflective element 26 in which the light emitting diode chip 21 is mounted and a lumiphor 27. A packaged LED which does not include any lumiphor (e.g., a 600 nm to 630 nm light emitting diode) can be constructed in a similar way but without the inclusion of a lumiphor 27. Persons of skill in the art are familiar with, and have ready access to, a wide variety of other packaged and unpackaged LED structures, any of which can, if desired, be employed according to the present invention. In some embodiments according to the present invention, one or more of the light emitting diodes can be included in a package together with one or more of the lumiphors, and the one or more lumiphor in the package can be spaced from the one or more light emitting diode in the package to achieve improved light extraction efficiency, as described in U.S. Patent Application No. 60/753,138, filed on Dec. 22, 2005, entitled “Lighting Device” (inventor: Gerald H. Negley), the entirety of which is hereby incorporated by reference. In some embodiments according to the present invention, two or more lumiphors can be provided, two or more of the lumiphors being spaced from each other, as described in U.S. Patent Application No. 60/761,310, filed on Jan. 23, 2006, entitled “Shifting Spectral Content in LEDs by Spatially Separating Lumiphor Films” (inventors: Gerald H. Negley and Antony van de Ven), the entirety of which is hereby incorporated by reference. In some lighting devices according to the present invention, there are further included one or more power sources, e.g., one or more batteries and/or solar cells, and/or one or more standard AC power plugs. The lighting devices according to the present invention can comprise any desired number of solid state light emitters and lumiphors. For example, a lighting device according to the present invention can include 50 or more light emitting diodes, or can include 100 or more light emitting diodes, etc. In general, with current light emitting diodes, greater efficiency can be achieved by using a greater number of smaller light emitting diodes (e.g., 100 light emitting diodes each having a surface area of 0.1 mm2 vs. 25 light emitting diodes each having a surface area of 0.4 mm2 but otherwise being identical). Analogously, light emitting diodes which operate at lower current densities are generally more efficient. Light emitting diodes which draw any particular current can be used according to the present invention. In one aspect of the present invention, light emitting diodes which each draw not more than 50 milliamps are employed. The sources of visible light in the lighting devices of the present invention can be arranged, mounted and supplied with electricity in any desired manner, and can be mounted on any desired housing or fixture. Skilled artisans are familiar with a wide variety of arrangements, mounting schemes, power supplying apparatuses, housings and fixtures, and any such arrangements, schemes, apparatuses, housings and fixtures can be employed in connection with the present invention. The lighting devices of the present invention can be electrically connected (or selectively connected) to any desired power source, persons of skill in the art being familiar with a variety of such power sources. Representative examples of arrangements of sources of visible light, mounting structures, schemes for mounting sources of visible light, apparatus for supplying electricity to sources of visible light, housings for sources of visible light, fixtures for sources of visible light, power supplies for sources of visible light and complete lighting assemblies, all of which are suitable for the lighting devices of the present invention, are described in: (1) U.S. Patent Application No. 60/752,753, filed on Dec. 21, 2005, entitled “Lighting Device” (inventors: Gerald H. Negley, Antony Paul van de Ven and Neal Hunter; attorney docket no. 931—002 PRO), the entirety of which is hereby incorporated by reference, and U.S. patent application Ser. No. 11/613,692, filed Dec. 20, 2006; (2) U.S. Patent Application No. 60/798,446, filed on May 5, 2006, entitled “Lighting Device” (inventor: Antony Paul van de Ven; attorney docket no. 931—008 PRO), the entirety of which is hereby incorporated by reference, and U.S. patent application Ser. No. 11/743,754, filed May 3, 2007; (3) U.S. Patent Application No. 60/845,429, filed on Sep. 18, 2006, entitled “LIGHTING DEVICES, LIGHTING ASSEMBLIES, FIXTURES AND METHODS OF USING SAME” (inventor: Antony Paul van de Ven; attorney docket no. 931—019 PRO), the entirety of which is hereby incorporated by reference; (4) U.S. Patent Application No. 60/846,222, filed on Sep. 21, 2006, entitled “LIGHTING ASSEMBLIES, METHODS OF INSTALLING SAME, AND METHODS OF REPLACING LIGHTS” (inventors: Antony Paul van de Ven and Gerald H. Negley; attorney docket no. 931—021 PRO), the entirety of which is hereby incorporated by reference; (5) U.S. Patent Application No. 60/809,618, filed on May 31, 2006, entitled “LIGHTING DEVICE AND METHOD OF LIGHTING” (inventors: Gerald H. Negley, Antony Paul van de Ven and Thomas G. Coleman; attorney docket no. 931—017 PRO), the entirety of which is hereby incorporated by reference; and (6) U.S. Patent Application No. 60/858,558, filed on Nov. 13, 2006, entitled “LIGHTING DEVICE, ILLUMINATED ENCLOSURE AND LIGHTING METHODS” (inventor: Gerald H. Negley; attorney docket no. 931—026 PRO), the entirety of which is hereby incorporated by reference. The light emitting diodes and lumiphors can be arranged in any desired pattern. In some embodiments according to the present invention which include 600 nm to 630 nm light emitting diodes as well as 430 nm to 480 nm light emitting diodes, some or all of the 600 nm light emitting diodes are surrounded by five or six 430 nm to 480 nm light emitting diodes (some or all of which may or may not include 555 nm to 585 nm lumiphors), e.g., the 600 nm to 630 nm light emitting diodes and the 430 nm to 480 nm light emitting diodes are arranged in generally laterally arranged rows and spaced from one another substantially evenly, each row being laterally offset from the next adjacent (in a longitudinal direction) row by half the distance between laterally adjacent light emitting diodes, with, in most locations, two 430 nm to 480 nm light emitting diodes being located between each 600 nm to 630 nm light emitting diode and its nearest neighbor in the same row, and with the 600 nm to 630 nm light emitting diodes in each row being offset from the nearest 600 nm to 630 light emitting diode(s) in the next adjacent (in a longitudinal direction) row by one and a half times the distance between laterally spaced adjacent light emitting diodes. Alternatively or additionally, in some embodiments according to the present invention, some or all of the brighter light emitting diodes are placed closer to a center of the lighting device than the dimmer light emitting diodes. The devices according to the present invention can further comprise one or more long-life cooling device (e.g., a fan with an extremely high lifetime). Such long-life cooling device(s) can comprise piezoelectric or magnetorestrictive materials (e.g., MR, GMR, and/or HMR materials) that move air as a “Chinese fan”. In cooling the devices according to the present invention, typically only enough air to break the boundary layer is required to induce temperature drops of 10 to 15 degrees C. Hence, in such cases, strong ‘breezes” or a large fluid flow rate (large CFM) are typically not required (thereby avoiding the need for conventional fans). In some embodiments according to the present invention, any of the features, e.g., circuitry, as described in U.S. Patent Application No. 60/761,879, filed on Jan. 25, 2006, entitled “Lighting Device With Cooling” (inventors: Thomas Coleman, Gerald H. Negley and Antony van de Ven), the entirety of which is hereby incorporated by reference, can be employed. The devices according to the present invention can further comprise secondary optics to further change the projected nature of the emitted light. Such secondary optics are well-known to those skilled in the art, and so they do not need to be described in detail herein—any such secondary optics can, if desired, be employed. The devices according to the present invention can further comprise sensors or charging devices or cameras, etc. For example, persons of skill in the art are familiar with, and have ready access to, devices which detect one or more occurrence (e.g., motion detectors, which detect motion of an object or person), and which, in response to such detection, trigger illumination of a light, activation of a security camera, etc. As a representative example, a device according to the present invention can include a lighting device according to the present invention and a motion sensor, and can be constructed such that (1) while the light is illuminated, if the motion sensor detects movement, a security camera is activated to record visual data at or around the location of the detected motion, or (2) if the motion sensor detects movement, the light is illuminated to light the region near the location of the detected motion and the security camera is activated to record visual data at or around the location of the detected motion, etc. For indoor residential illumination a color temperature of 2700k to 3300k is normally preferred, and for outdoor flood lighting of colorful scenes a color temperature approximating daylight 5000K (4500-6500K) is preferred. Any two or more structural parts of the lighting devices described herein can be integrated. Any structural part of the lighting devices described herein can be provided in two or more parts (which can be held together, if necessary). Furthermore, while certain embodiments of the present invention have been illustrated with reference to specific combinations of elements, various other combinations may also be provided without departing from the teachings of the present invention.
