Illuminating device comprising solid state light emitter [Reciprocal Reference of Related Applications]
The present application claims the benefit of U.S. Patent Application Serial No. 12/566, 861, filed on Sep. 25, 2009, which is incorporated herein by reference.
The subject technology of the present invention is directed to a light emitting device. In some aspects, the subject technology of the present invention is directed to a light emitting device comprising one or more solid state illuminators, such as one or more light emitting diodes.
Efforts to develop more energy efficient systems continue. Most of the electricity generated each year in the United States (some estimated to be as high as 25 percentage points) is used for illuminating, a large part of which is general lighting (eg, downlights, searchlights, spotlights and other general residences or Commercial lighting products). Therefore, it is necessary to continue to provide more energy-efficient lighting.
Solid state illuminators (eg, light-emitting diodes) receive more attention due to their energy efficiency. It is well known that incandescent light bulbs are very non-energy-saving light sources - about ninety percent of the power they consume is released by heat rather than light. Fluorescent bulbs are more efficient (about 10 times different) than incandescent bulbs, but still less efficient than solid state illuminators, such as light-emitting diodes.
Moreover, incandescent bulbs have a relatively short life span, i.e., substantially about 750-1000 hours, compared to the normal life of solid state illuminators such as light-emitting diodes. In contrast, light-emitting diodes, for example, have a basic lifetime between 50,000 and 70,000 hours. Fluorescent bulbs typically have a longer life (eg, 10,000-20,000 hours) than incandescent lamps, but they basically provide a much worse color reproduction. Conventional fixtures have a basic life of about 20 years, which corresponds to a luminaire usage of at least about 44,000 hours (based on a 20-hour daily usage rate of 20 years). Where the life of the illuminator of the illuminator is less than the life of the fixture, there is a need for periodic replacement. The impact of the need to replace illuminators is particularly significant where it is difficult to use (eg, arched ceilings, bridges, high-rises, highway tunnels) and/or where replacement costs are very high.
There are many challenges in using a light-emitting diode in a light-emitting device. In many cases, additional components can be added to the illumination device to address these challenges. Additional components tend to increase the weight of the illumination device as well as the size of the illumination device. It is desirable to provide illumination devices comprising one or more solid state illuminators, wherein such challenges can be addressed, and yet the illumination devices are lightweight and/or can be suitably placed for comparison to provide conventional illumination The same or substantially the same space of the device (eg, a light emitting device including one or more incandescent light sources and/or one or more fluorescent light sources). The ability to make the illumination device lightweight and/or suitable for placement in a space similar (or equivalent) to that of a conventional device, when retrofitting the illumination device, and when installing the illumination device in a new architecture (more Don't mention that it is important when shipping it.
One such challenge that arises from the fact that the luminescence spectrum of any particular luminescent diode is substantially concentrated near a single wavelength (as specified by the components and structures of the luminescent diode), which is satisfactory for some applications However, it is not satisfactory to others (for example, in terms of providing general illumination, this luminescence spectrum generally does not provide light that appears in white, and/or provides a very low color rendering index). As a result, in many situations (eg, making a device that emits light that is perceived as white or near white, or making a device that emits light that is not highly saturated), applying a light source that emits light of a different color (eg, one or more solid state lighting) And optionally also one or more other types of light sources, such as additional light emitting diodes, luminescent materials, incandescent light, etc., are necessary. There are many different factors that cause one or more solid state illuminators to stop illuminating and/or change in their luminous intensity, which eliminates the balance of color output and causes the illuminating device to emit a color that is perceived to be different from the desired color of the light output. The light. As a result, in many of these devices, one challenge that must include additional components is that we would like to provide additional circuitry that can adjust the current supplied to the individual solid state illuminators (and/or other illuminators) to be able to sustain The balance of the color output between the illuminators of different color lights in order to get the desired color output. Another such challenge is that we want to mix different colors of light emitted from different solid state illuminators by providing additional structure to assist in this mixing.
One example of a factor in which one or more solid state illuminators can change in their luminous intensity is temperature variation (eg, due to changes in ambient temperature and/or heating of solid state illuminators). Certain types of solid state illuminators (eg, solid state illuminators that emit light of different colors) experience differences in illuminance at different temperatures (if supplied with the same current), and often, such changes in intensity occur with The temperature changes to emit different wavelengths of light on different illuminators. For example, certain light-emitting diodes that emit red light have very strong temperature dependence in at least some temperature ranges (eg, aluminum-indium gallium phosphide light-emitting diodes can reduce light output when heated to ~40 degrees C. 20%, that is, about -0.5% per degree C; some blue-emitting InGaN+YAG:Ce light-emitting diodes can reduce light output by about -0.15%/degree C).
Aging is another example of a factor that causes one or more solid state illuminators to vary in their luminous intensity. Some solid state illuminators (e.g., solid state illuminators that emit light of different colors) experience a reduction in luminescence intensity as they age (if the same current is supplied), and often such reductions in intensity occur at different rates.
Another example of a factor that causes one or more solid state illuminators to vary in their luminous intensity is damage to the solid state illuminator and/or damage to the circuitry that supplies the solid state illuminator.
Another challenge that arises in the fabrication of light-emitting devices having light-emitting diodes often must include additional components that are such that the performance of many solid-state illuminators can be reduced as they are subjected to temperature increases. For example, many light-emitting diode sources have decades of average operating life compared to many incandescent bulbs for only a few months or 1-2 years, but some LEDs have a lifetime that operates at elevated temperatures. The situation will be significantly shortened. If you want a long life, manufacturers will recommend that the junction temperature of the LED should not exceed 85 °C. In many cases, it is desirable to offset such problems by providing additional structures (or structures) to provide a desired degree of heat dissipation.
Another challenge that arises in the fabrication of light-emitting devices having light-emitting diodes often must include additional components that result in a relatively high light output from a relatively small area provided by the solid state illuminator. This concentration of light output can present challenges in providing solid state lighting systems for general illumination, where, in general, large differences in brightness in small areas can be perceived as flashes, which can be distracting the owner. . Therefore, in many cases, we would like to provide additional structure to assist in mixing the emitted light and/or to create the sensation that the emitted light will be output through a larger area.
Another challenge that arises in the manufacture of light-emitting devices having light-emitting diodes often must include additional components that are such that the light-emitting diodes are substantially most efficiently operated at low voltage DC power while the wires The voltage is basically a very higher voltage AC power. As a result, it is often desirable to be able to provide a conversion line voltage, such as a circuit from alternating current to direct current and/or voltage reduction.
Moreover, in some cases, it is desirable to retrofit or mount the lighting device in a circuit having a conventional dimmer. Such dimmers operate in accordance with signals contained in the power supplied to the illumination device (e.g., a duty cycle of an alternating current signal, such as from a triode flow switch), and additional circuitry is generally necessary.
An example of a light-emitting device that includes some or all of such different additional components, is retrofitted into many conventional embedded light-emitting enclosures and operates with many conventional dimmers, is a light-emitting diode illumination method from NC, Morrisville, Cree. LR6. The LR6 is a 6" built-in downlight that provides 650 to deliver lumens, consumes only 12 watts of electrical power, and has a color rendering index of 92. The weight of the LR6 is slightly less than 1 kg.
It is desirable for us to be able to fabricate a light-emitting device comprising a solid-state illuminator for use in a lightweight light-emitting device (eg, as compared to other light-emitting devices comprising solid state light emitters, for example including one or more solid state light emitters and provided herein) Some or all of the features of the device) result in high wall socket efficiency while providing a good color quality for blending, proper brightness, and good solid state illuminator life.

As used herein, the term "illumination" (or 〝 illuminated) when used in solid state illuminators means that at least some power is applied to the solid state illuminator to cause the solid state illuminator to emit at least some electromagnetic radiation (eg, , visible light). The phrase 〝 is illuminated to include a solid state illuminator to continuously or intermittently emit electromagnetic radiation at a rate that is perceptible to the human eye when electromagnetic radiation is continuously or intermittently emitted, or for example to cause the human eye to perceive them when continuously or intermittently emitting light In this manner, a plurality of solid state illuminators of the same color or different colors are intermittently and/or alternately (with or without overlap in the 〝 opening time) to emit electromagnetic radiation (and, in different colors, in individual colors or a mixture of those colors to emit in some cases).

The wording illuminating device used herein is not limited except that it indicates that the device is capable of emitting light. That is, the lighting device can be a device that illuminates an area or volume, for example, structure, swimming pool or spa, room, warehouse, display, road, parking lot, car, traffic lights such as road traffic signs, advertising billboards, ships , toys, mirrors, ships, electronic devices, boats, airplanes, playgrounds, computers, remote control sound devices, remote control imaging devices, cell phones, trees, windows, LCD screens, caves, tunnels, courtyards, street lampposts, or lighting chambers Or device arrays, or devices for edge or backlighting (eg, backlit advertising, backlit traffic lights, LCD screen displays), light bulb replacement (eg, for replacing alternating current incandescent light, low voltage light, fluorescent light, etc.) Light for outdoor lighting, light for safe lighting, light for external residual lighting (wall mounting, column/column mounting), ceiling fixture/wall torch, under cabinet lighting, light bulb (floor) And/or dining table and/or desk), landscape lighting, track lighting, work lighting, special lighting, ceiling Fan lighting, files / artistic display lighting, high vibration / impact lighting a high work lights, etc., mirrors / reading lights, or any other light emitting devices.
As used herein, the term "shielding angle" means the minimum angle associated with the surface on which the illuminating device is mounted, which extends from the illuminating device to the solid state illuminator (or solid state illuminators) in the illuminating device and/or The lens cannot be defined by a line segment at the location of the direct view (eg, the solid state illuminator or lens will be blocked by a portion of the illumination device). Therefore, if the shielding angle of the illuminating device is specifically specified to be at least equal to a certain angle (for example, at least 15 degrees), then if the position is connected to the line segment of the illuminating device to define an angle of 15 degrees or more (which is related) On the surface on which the illuminating device is mounted, such as the ceiling, no light exiting the illuminator will travel directly from the solid state illuminator (or lens) to that location. In other words, if, for example, a person starts from a position directly below the recessed downlight with a lens and moves away from that position, at that point, that person will arrive at the lens of the recessed downlight while watching The position to be shielded; the person moves further and the angle becomes smaller. Therefore, if the illuminating device has a higher minimum shielding angle (all other things are equal), that person will have to move a shorter distance before the embedded downlight is shielded during viewing (ie, that person is tied A position begins, which together with the illumination device defines a 90 degree angle associated with the surface on which the illumination device is mounted, and the angle becomes smaller as he or she moves. Thus, for example, if the illumination device is embedded further forward (if any), the shielding angle will be higher.
The color of the visible light output by the illuminator and/or the color of the mixed visible light output by the plurality of illuminators can be represented in the 1931 CIE (International Commission on Illumination) chroma map or the 1976 CIE chroma map. Those skilled in the art will be familiar with these figures and these figures are easy to use (e.g., by searching the Internet for a CIE chroma map).
The CIE chroma map details the perception of color by the CIE parameters x and y (in the case of the 1931 map) or u' and v' (in the case of the 1976 diagram). Each point on the individual map (i.e., each color point 〞) corresponds to a particular color. For a technical description of the CIE chroma map, see, for example, Encyclopedia of Physical Science and Technology, Vol. 7, 230-231 (Robert A Meyers ed, 1987). The spectral color is distributed around the boundaries of the contour space, including all the colors perceived by the human eye. This boundary represents the maximum saturation of the spectral color.
The 1931 CIE chroma map can be used to define colors as a weighted sum of different colors. The 1976 CIE chroma map is similar to the 1931 graph, except that the similar distances on the 1976 graph represent similarly perceived color differences.
In the 1931 diagram, the offset from a point on the map (i.e., the 〝 color point 可) may be expressed in accordance with the x, y coordinates or both to generate an indication of the perceived color difference range from the MacAdam ellipse. For example, from the specific specified color defined by a particular set of coordinates on the 1931 map, it is defined as the trajectory of the points of the ten MacAdam ellipse, which are perceived by each of them as being of a common color different from the specified color. The composition (and, as such, by the other number of MacAdam ellipse is defined as the trajectory of the point separating the particular color).
Since the similar distance on the 1976 graph represents a similar difference perceived in the color, the offset from the point on the 1976 graph can be expressed as the distance from the point based on the coordinates u' and v' = (Δu) ' 2 +Δv' 2 )1/2. In the scale of the u'v' coordinate, this formula produces a value that corresponds to the distance between the points. Each of the colors defined by the point trajectories of a predetermined distance from a predetermined color point is composed of colors each of which is perceived to be different from the prescribed color to a general degree.
A series of points typically represented on a CIE map will be treated as a blackbody locus. The chroma coordinates (ie, color points) placed along the black body locus will follow the Planck equation: E(λ)=Aλ -5 /(e (B/T) -1), where E is the luminous intensity, λ is the emission wavelength, T is the color temperature of the black body, and A and B are constant. The 1976 CIE diagram includes a list of temperatures along the blackbody locus. These temperature lists show the color path of the black body radiator that is added to such temperatures. When a heating body becomes incandescent, it first emits a red glow, then yellow, then white, and finally blue. This occurs because the wavelength associated with the peak radiation of the black body radiator gradually increases as the temperature increases, which is consistent with the Wien Displ AC ement law. Illumination of light is produced on or near the blackbody locus, which can therefore be accounted for by their color temperature.
The most common type of general illumination is white light (or near white light), that is, light that is close to the black body locus, such as within about 10 MacAdam ellipses of the black body locus on the 1931 CIE chroma map. Light with such an approximate black body trajectory is considered to be white light depending on its brightness, even though some of the light within the 10 MacAdam ellipse of the black body trajectory is dyed to some extent, such as light from an incandescent bulb. It will be called a 〝 white 〞, even if it sometimes has a golden or red coloration; likewise, if the light with a correlated color temperature of 1500K or less is excluded, the very red ray along the black body trajectory will be excluded.
The term "white light" as used herein means that the color point has no more than 0.01 unit distance (u'v' coordinate specification) or 10 McAdam ellipse at the closest point on the black body locus in the 1976 CIE chroma map. Light inside. In some embodiments of the subject matter of the present invention, including some embodiments that include or do not include any of the features discussed herein, the light emitted by the illumination device is within five MacAdam ellipse, in some cases In the three MacAdam ellipse, at least one of them is on the black body locus.
The wording wall socket efficiency used herein is measured in lumens per watt, which is the number of lumens leaving the illumination device divided by the total energy supplied to produce light, relative to the individual The value of the component and/or component component. Therefore, the wall socket efficiency used herein takes into account all losses, including any quantization loss, that is, the ratio of the number of photons emitted by the luminescent material divided by the number of photons absorbed by the luminescent material, any Stokes loss, That is, the loss due to the frequency variation associated with light absorption and visible light re-emission (eg, by luminescent material), the loss in converting the line power into the power supplied to the illuminator, and the true exit from the illuminating device. Any optical loss associated with the light emitted by the illuminator component. In some embodiments, illumination devices in accordance with the subject art of the present invention are when they are supplied with alternating current power (i.e., where the alternating current power is converted to direct current power before being supplied to some or all of the components, the illumination The device can also withstand losses from such conversions, such as AC line voltage, which will provide the wall socket efficiency specified herein. The wording line voltage is used according to its well-known usage rate to mean the power supplied by the energy source, such as the power supplied from the grid, including alternating current and direct current.

Solid-state illumination in any of the light-emitting devices according to the subject technology of the present invention , or one or more solid state illuminators, can be mounted directly on the conditioning element (and/or, when the mixing chamber subassembly is included, directly on a portion of the mixing chamber subassembly) . In such devices, power can be transferred to the solid state illuminator or solid state illuminators that are mounted directly on the conditioning element (and/or on a conditioning element) in any suitable manner, such as via Conductive tracks (and/or mixing chamber subassemblies) on the trim element, via wires connected to one or more circuit boards, via tracks embedded in the trim elements (and/or mixing chamber subassemblies), via extension Contacts that have been trimmed (and/or mixed chamber subassemblies) and so on.
Mounting the solid state illuminator directly on the conditioning element (and/or the mixing chamber subassembly) reduces or minimizes the thermal interface between the solid state illuminator and the surrounding environment, where the conditioning element (and/or The mixing chamber subassembly) acts as a heat sink for the solid state illuminator, which is tied and exposed to the room. Mounting the solid state illuminator directly on the trim component (and/or the mixing chamber subassembly) also eliminates the cost of the metal core circuit board. In other devices, one or more solid state illuminators can be mounted on a circuit board (eg, a metal core circuit board) that can be mounted on the trim component (and/or the mixing chamber subassembly) .

Or alternatively, adjacent to the solid state illumination A portion of the heat sink of the device (or solid state illuminators) can be removed (and optionally filled with a thermal element or a portion of the thermal element). The heat element is made of any suitable material and is of any suitable shape. The use of materials having higher thermal conductivity in the manufacture of thermal elements generally provides greater heat transfer, and the use of thermal elements having a larger surface area and/or cross-sectional area generally provides greater heat transfer. Representative example materials that can be used to create a thermal element, including metals, diamonds, diamond-like carbon, and the like, can be used.
One aspect of the trimming element described herein can be a body structure trimming element that includes a thermally conductive material and is configured to extend from within the embedded casing through a void in the embedded casing. It also includes a flange member that extends beyond the aperture of the built-in casing and prevents the individual structural conditioning elements from being fully inserted within the embedded casing.
