FIELD OF THE INVENTION The present invention includes a lighting device, particularly one or more solid state light emitters and one or more luminescent materials (eg, one or more phosphor emitters). Related to the device. The present invention is also directed to a lighting method.

BACKGROUND OF THE INVENTION Each year, much of the electricity generated in the US (some estimates are as high as 25%) goes to lighting. There is therefore an ongoing need to provide more energy efficient lighting. It is well known that incandescent bulbs are inefficient energy sources—about 90% of the electricity they consume is released as heat rather than light. Fluorescent bulbs are more efficient (about 10 times) than incandescent bulbs, but are still very inefficient when compared to solid state light emitting devices such as light emitting diodes.

  Furthermore, incandescent bulbs have a relatively short life, for example typically about 750-1000 hours, compared to the normal life of a solid state light emitting device. In comparison, a light emitting diode has a lifetime between, for example, 50,000 hours and 70,000 hours. Fluorescent lamps have a longer life than incandescent lamps (eg, 10,000-20,000 hours), but color reproduction is less preferred.

  Color reproduction is typically measured using a computed color evaluation number (CRI). Ra is a relative measurement of how the computed color evaluation of the lighting system is compared to that of the reference illuminator (light source). Black body radiation is used for a color temperature of 5,000K, and a series of spectra defined by the CIE (International Commission on Illumination) is used for color temperatures above 5,000K. CRI Ra is the average of the difference in surface color of an object when illuminated by a particular lamp relative to the surface color of the object when illuminated by a reference light source. The CRI Ra is equal to 100 if the color coordinates of a set of test colors illuminated by the illumination system are the same as the coordinates of the same test colors illuminated by the reference radiator. Daylight has a high CRI (Ra is approximately 100), incandescent bulbs are also relatively close (Ra is greater than 95), and fluorescent lights are less accurate (typical) 70-80 Ra). Some types of specialized lighting have very low CRI (eg, mercury vapor, or chlorine lamps have low Ra, such as about 40, or even lower). Chlorine light, for example, is used for light highways, but the driver response time decreases with lower CRI values (for any given brightness, visibility is lower Decreases the more you have it.

  The problem faced by conventional lighting equipment is the need to periodically replace lighting devices (eg, light bulbs). Such problems are expressed particularly where access is difficult (eg, vaulted ceilings, bridges, tall buildings, traffic tunnels) and / or where replacement costs are extremely high. The typical lifetime of a conventional light fixture is about 20 years, corresponding to at least about 44,000 hours of light generator use (based on 6 hours of use per day over 20 years). The lifetime of the light generator is typically much smaller, which creates the need for periodic replacement.

  Thus, for these and other reasons, efforts have been made to develop methods in which solid state light emitters can be used in wide area applications in place of incandescent bulbs, fluorescent lamps, and other light generating devices. Has been continued. Furthermore, where light emitting diodes (or other solid state light emitting devices) continue to be used, efforts include, for example, energy efficiency, color rendering index (CRI), contrast, effectiveness (lm / W), And / or continues to be done to provide improved light emitting diodes with respect to service periods.

  A light emitting diode is a semiconductor device that converts current into light. A wide range of different solid state light emitting diodes are still being used in an increasingly wide field for a wide range of purposes.

  More specifically, a light emitting diode is a semiconductor device that emits light (ultraviolet light, visible light, or infrared light) when a potential difference is applied to a pn junction structure. There are many known ways of making light emitting diodes and many related structures, and the invention can use any such device. For example, chapters 12-14 of Sze semiconductor device physics (1981, 2nd edition) and Sze modern semiconductor device physics (1998) include a wide range of light emitting diodes. A photon device is described.

  Commonly recognized and commercially available “LEDs” that are sold in an electronic shop (for example) represent “packaged” devices made from many parts. These packaged devices are typically semiconductors as described in (but not limited to) US Pat. Nos. 4,918,487; 5,631,190; and 5,912,477. Base light emitting diode; includes various wire connections and packages containing light emitting diodes.

  As is well known, light emitting diodes produce light by exciting electrons across the band gap between the conduction band and valence band of a semiconductor active (light emitting) layer. The electron transition generates light at a wavelength that depends on the energy gap. Thus, the color (wavelength) of the light emitted by the light emitting diode depends on the semiconductor material of the active layer of the light emitting diode.

  While the development of light emitting diodes has reformed the lighting industry in many ways, some of the features of light emitting diodes have presented many challenges, some of which are not yet fully met. For example, the emission spectrum of any particular light-emitting diode is typically concentrated around a single wavelength (as predicted by the composition and structure of the light-emitting diode), which may be useful for some applications. Preferred but not preferred for others (eg, to provide illumination, such an emission spectrum gives a very low CRI).

  Since light perceived as white is necessarily a blend of two or more colors (or wavelengths), so that a single light emitting diode junction can produce white, It has not been developed. “White” light emitting lamps have been manufactured with light emitting diode pixels formed by red, green and blue light emitting diodes, respectively. Other “white” light emitting diodes are (1) light emitting diodes that emit blue light, and (2) luminescent materials that emit yellow light in response to excitation by light emitted by the light emitting diodes (eg, phosphorescent light emitting). The blue light and yellow light, when mixed, produce light that is perceived as white light.

  Furthermore, the mixing of primary colors that produce a combination of non-primary colors is generally well understood in this and other techniques. In general, the 1931 CIE chromaticity diagram (international standard for major colors established in 1931) and the 1976 CIE chromaticity diagram (similar to the 1931 chromaticity diagram, but similar on the diagram) Has been modified to represent similar color differences.) Provides a useful reference for defining a color as a weighted addition of primary colors.

  The light emitting diodes can thus be used individually, or in any combination, optionally with one or more luminescent materials (phosphor emitters or scintillators) and / or filters. Desired perceived colors (including white) can be generated. Thus, efforts are made to replace existing light sources with light emitting diode light sources to improve, for example, energy efficiency, color rendering index (CRT), effectiveness (lm / W), and / or service duration. The continuing region is not limited to any particular color light or color blend light.

  A wide variety of luminescent materials (e.g., also known as lumiphors or luminophoric materials as disclosed in U.S. Patent 6,600,175, which is hereby incorporated by reference in its entirety). Are known and available to those skilled in the art. For example, a phosphor emitter is a luminescent material that emits reactive radiation (eg, visible light) when excited by an excitation radiation source, for example. In many cases, the responsive radiation has a wavelength that is different from the wavelength of the exciting radiation. Other examples of luminescent materials include scintillators, daylight glow tapes, and inks that shine in the visible spectrum when irradiated with ultraviolet light.

  Luminescent materials are those that down-convert, i.e., materials that convert photons to lower energy levels (longer wavelengths), or those that up-convert, i.e., photons to higher energy levels (shorter wavelengths). It can be classified as being a material to convert.

  Inclusion of the luminescent material in the LED device may include, as described above, the luminescent material into a clean or translucent containment material (eg, epoxy-based, silicone-based, or glass-based material), eg, blending or coating It has been accomplished by adding processes.

  For example, US Pat. No. 6,963,166 (Yano'166) discloses that a conventional light-emitting diode lamp is a light-emitting diode chip, a bullet-shaped transparent housing for covering the light-emitting diode chip, and supplying current to the light-emitting diode chip. And a cup reflector for reflecting the radiation of the light-emitting diode chip in a certain direction, wherein the light-emitting diode chip is accommodated by a first resin portion, which further comprises a second It is disclosed that it is contained by the resin portion. According to Yano '166, the first resin portion fills the cup reflector with resin material, and the light emitting diode chip is mounted on the bottom of the cup reflector, after which its cathode and anode electrodes are It is obtained by curing after being electrically connected to the lead by a wire. According to Yano'166, the phosphor phosphor is dispersed in the first resin portion so as to be excited by the light A emitted from the light emitting diode chip, and the excited phosphor phosphor has a longer wavelength than the light A. And a portion of the light A is transmitted through a first resin portion that includes a phosphor emitter, resulting in a mixture of light A and light B. Light C is used as illumination.

  As noted above, “white LED light” (ie, light perceived as white or close to white) has been studied as a possible replacement for white incandescent bulbs. Typical examples of white LED lamps are indium gallium nitride (InGaN) or blue light emitting diode chip packages made from gallium nitride (GaN), which are coated with a phosphor phosphor such as YAG. Including. In such an LED lamp, the blue light emitting diode chip produces radiation having a wavelength of about 450 nm, and the phosphor emitter produces yellow fluorescence having a peak wavelength of about 550 nm when receiving the radiation. For example, in one design, white light emitting diodes are manufactured by forming a ceramic phosphor phosphor layer on the outer surface of a blue light emitting semiconductor light emitting diode. Part of the blue light emitted from the light emitting diode chip passes through the phosphor light emitter, while part of the blue light emitted from the light emitting diode chip is absorbed by the phosphor light emitter, which is excited. Emits yellow light. Part of the blue light emitted from the light emitting diode chip and passed through the phosphor emitter is mixed with the yellow light emitted by the phosphor emitter. The observer perceives a mixture of blue and yellow light as white light.

  As noted above, in another type of LED lamp, the light emitting diode chip that emits ultraviolet light includes a phosphor phosphor material that generates red (R), green (G), and blue (B) rays. Are combined. In such “RGB LED lamps”, the ultraviolet light emitted from the light emitting diode chip excites the phosphor emitter and causes the phosphor emitter to emit red, green and blue light, which are When mixed, it is perceived as white light by the human eye. Thus, white light can also be obtained as a mixture of these rays.

  Existing LED component packages and other electronic circuits have been given designs that are assembled into one electrical installation. In such a design, the packaged LED is mounted directly to a circuit board or heat sink, the circuit board is mounted to the heat sink, and the heat sink is mounted to a fixed housing along with the desired drive electronics. . In many cases, additional optical components (secondary to package components) are also required.

  In replacing a light emitting diode instead of another light source, such as an incandescent bulb, the packaged LED includes conventional light fixtures, such as a hollow lens and a base plate attached to the lens, the base plate comprising: It has been used for light fixtures having a conventional socket housing with one or more contacts electrically coupled to a power source. For example, the LED light bulb is adapted to be connected to an electrical circuit board, a plurality of packaged LEDs mounted on the circuit board, and the socket housing of the light emitting equipment attached to the circuit board. The plurality of LEDs can be illuminated by a power source.

Using white light emitting devices, eg light emitting diodes, in a wider variety of applications, white light, improved energy efficiency, improved CRI, improved effectiveness (lm / W) And / or with a longer service period, there is an ongoing demand for how to give.

Brief summary of the invention
Although relatively efficient, typically has a CRI Ra value lower than 75, has poor color rendering, and is particularly defective in red rendering and defective to a significant extent in green There is a “white” color LED light source. This includes many things including typical human face colors, food items, labeling, painting, posters, signs, apparel, home decorations, plants, flowers, cars, etc. Incandescent lights, or natural daylight Means representing strange or bad colors compared to being illuminated with. Typically, such white LEDs have a color temperature of about 5000 K, which is generally not visually pleasing for general lighting, but this is not commercially produced, or advertising and printing Illumination of the recorded material may be desirable.

  Some so-called “warm white” LEDs have a more acceptable color temperature for indoor use (2700-3500K) and a good CRI (Ra = 95 for yellow and red phosphor phosphor mixtures) However, their effectiveness is much less than half that of standard “cold white” LEDs.

  Colored objects illuminated by RGB LED lamps sometimes do not appear in their true colors. For example, an object that reflects only yellow light and therefore appears to be yellow when illuminated by white light will have a clear yellow color produced by the red and green LEDs of the RGB LED light fixture. When illuminated by the light it has, it is separated from saturation and appears gray. Such a light installation is therefore considered not to give an excellent color rendition, especially when illuminating various settings as in general lighting and especially with respect to natural scenes. Furthermore, currently available green LEDs are bandage inefficient, thus limiting the efficiency of such lamps.

  Using LEDs with a wide variety of shades also necessitates the use of LEDs with a wide range of efficiencies, including some with low efficiencies, thereby allowing such systems Reduce the efficiency of the network, dramatically increase the complexity and cost of circuitry to control many different types of LEDs, and maintain the color balance of the light.

  Therefore, combining the efficiency and lifetime of white LEDs (ie avoiding the use of relatively inefficient light sources) with an acceptable color temperature and good color rendering index, a wide variety of and simple control circuitry There is a need for a highly efficient white light source.

  In accordance with the present invention, it has been unexpectedly discovered that a surprisingly high CRI can be obtained by combining the following (1), (2) and (3): ) One or more light emitting diodes emitting light having a peak wavelength in the range of 430 nm to 480 nm, (2) one emitting light having a dominant wavelength in the range of 555 nm to 585 nm, or Light emitted from more Lumiphors, and (3) Light emitted from one or more light emitting diodes that emit light having a dominant wavelength in the range of 600 nm to 630 nm.

In particular, a high CRI may further be achieved if the light emitting diodes and lumiphors are illuminated if each of the first group of light emitting diodes is illuminated and each of the first group of lumiphors is excited. The mixture of light from a group of light emitting diodes and from the first group of lumiphors is, in the absence of any additional light, a first group of mixed illumination, On the 1931 CIE chromaticity diagram, with x, y color coordinates in the region surrounded by the first, second, third, fourth, and fifth line segments, the first line segment is Connecting the first point to the second point, the second line segment connecting the second point to the third point, and the third line segment connecting the third point to the fourth point Connected to a point, the fourth line segment connects the fourth point to the fifth point, The fifth line segment connects the fifth point to the first point, the first point has x, y coordinates of 0.32, 0.40, and the second point is 0 The third point has x and y coordinates of 0.43 and 0.45, and the fourth point has 0.42 and 0.42.

  The light emitting diode may be saturated or may not be saturated. The term “saturated”, as used herein, means having a purity of at least 85%, the term “purity” has a meaning well known to those skilled in the art, and the purity The procedure for calculating is well known to those skilled in the art.

  Aspects related to the present invention can be expressed on either the 1931 CIE (International Commission on Lighting) chromaticity diagram or the 1976 CIE chromaticity diagram. FIG. 1 shows the 1931 CIE chromaticity diagram. FIG. 2 shows the 1976 chromaticity diagram. FIG. 3 shows an enlarged portion of the 1976 chromaticity diagram to show the location of the black body in more detail. Those skilled in the art are familiar with these diagrams, and these diagrams are readily available (eg, by searching for “CIE chromaticity diagrams” on the Internet).

  The CIE chromaticity diagram depicts human color sensitivity with two CIE parameters x and y (in the case of a 1931 chromaticity diagram) or u 'and v' (in the case of a 1976 chromaticity diagram). For a technical description of the CIE chromaticity diagram, see, for example, “Physics and Technology Encyclopedia”, Vol. 7, 230-231 (Robert A Mayer, 1987 edition). Spectral colors are distributed around the edges of the outlined space that contains all of the shades perceived by the human eye. The border line represents the maximum saturation for the spectral color. As mentioned above, the 1976 CIE chromaticity diagram has been modified so that the 1976 diagram in the 1976 chromaticity diagram represents similar perceived color differences in the same distance on the 1976 diagram. Other than that, it is similar.

  In the 1931 diagram, a deviation from a point on the diagram can be given either by coordinates or by a MacAdam ellipse to give an indication as to the degree of color difference perceived. For example, the location of a point defined as being within a 10-step MacAdam ellipse from a specified shade defined by a particular set of coordinates on a 1931 diagram may differ from the identified shade by a common range. Each of the perceived shades (and the same is true for the positions of points defined as being spaced from a particular shade by another amount of the MacAdam ellipse).

  Since a similar distance on the 1976 diagram represents a similar perceived color difference, the deviation from the point on the 1976 diagram can be represented by the coordinates u ′ and v ′, for example, point = (Δu ′ 2 + Δv '2) Each color can be expressed by a distance from 1/2, and the hue defined by the position of a point at a common distance from each specific hue differs from each other by a common degree. Made up of shades to be made.

  The chromaticity diagram coordinates and CIE chromaticity diagrams shown in FIGS. 1-3 are well documented in many books and other publications such as K.C. H. Butler, “Fluorescent Lamp Phosphor Phosphor” (Pennsylvania State University Press 1980), pages 98-107, and Brasse et al., “Luminescent Materials” (Springer Publishers 1994), pages 109-110, both incorporated herein by reference.

  The chromaticity coordinates (ie color points) lying along the blackbody locus are the Planck's equations: E (λ) = Aλ -5 / (e (B / T) −1) where E is the output intensity, λ is the emission wavelength, T is the color temperature of the black body, and A and B are constants. Color coordinates lying on or near the blackbody locus elicit fun white light for the human observer. The 1976 CIE diagram contains a list of temperatures along the blackbody locus. These temperature lists show the blackbody radiator color path that results in such an increase to temperature. When a heated object becomes incandescent, it first shines reddish, then shines yellowish, then shines white, and finally shines bluish. This occurs because the wavelength associated with the peak radiation of a blackbody radiator becomes increasingly shorter with increasing temperature, consistent with the Wien displacement method. Light emitters that produce light on or near the blackbody locus can thus be described by their color temperature.

  Also drawn on the 1976 CIE diagram are designations A, B, C, D, and E, which correspond as illuminators A, B, C, D, and E, respectively. It refers to the light generated by some standard illuminators identified.

  CRI Ra is a relative measure of how the color rendering of a lighting system is compared to that of a blackbody radiator or other defined reference. The CRI Ra is equal to 100 if the color coordinates of a set of test colors illuminated by the illumination system are the same as the coordinates of the same test colors emitted by the reference radiator.

  The invention will be more fully understood with reference to the accompanying drawings and the following detailed description of the invention.

Detailed Description of the Invention The expression "correlated color temperature" has a well-defined meaning (ie in a sense that can be easily and accurately determined by a person skilled in the art), the closest blackbody in color Used in accordance with its most well-known meanings. The expression “directly or switchably and electrically connected” means “directly and electrically connected” or “switchable and electrically connected”. To do.

  The sentence that two components in an apparatus are “directly and electrically connected” means that the insertion of the component between the components is a function provided by the device, or , Which means that any component that substantially affects multiple functions is not electrically present.

  For example, two components can be electrically connected even if they have a small resistance between them that does not substantially affect one or more functions provided by the device. Can be said to be connected (in fact, the wire connecting the two components can be considered to be a small resistance); In between, the device is identical except that it has additional electrical components that allow it to achieve additional functions, but does not include the additional components, One or more functions provided by the device can be said to be electrically connected if they do not substantially affect the function; It is continued, or wire on the circuit board or on opposite tracing end, two components that are directly connected, are electrically connected.

  The sentence here that two components in a device are “switchably electrically connected” means that a switch is placed between the two components and the switch is selectively Closed or opened, where if the switch is closed, the two components are directly and electrically connected and if the switch is open ( That is, during any time period in which the switch is open), means that the two components are not electrically connected.

  The expression “illuminated” as used herein when referring to a light emitting diode means that at least some current is supplied to the light emitting diode, causing the light emitting diode to emit at least some light. That means. The expression “illuminated” means that the light emitting diode emits light continuously, or the human eye perceives it as emitting light continuously. In a manner in which multiple light emitting diodes of the same color or of different colors will sense that they are emitting light continuously. , Intermittently and / or alternately (with time “on”, overlapping or non-overlapping), (and different colors being emitted as a mixture of those colors) In this case, the situation where light is emitted is also covered.

  When referring to a lumiphor, the expression “excited” as used herein means that at least some electromagnetic radiation (eg, visible light, UV light, or infrared light) is in contact with the lumiphor. This means that the Lumiphor is emitting some light.

  The expression “excited” means that the Lumiphor emits light continuously or intermittently at a rate at which the human eye perceives it as emitting light continuously. Intermittently, in such a way that multiple Lumiphors of the same color or of different colors will perceive the human eye to emit them continuously. And / or alternately (with time “on”, overlapping or non-overlapping), (and where different colors are emitted as a mixture of those colors) ), Covering the situation where light is emitted.

  One light emitting diode (or multiple light emitting diodes) used in a device according to the present invention, one lumiphor (or multiple lumiphors) used in a device according to the present invention may be any light emission known to those skilled in the art. It can be selected from diodes and lumiphors. A wide variety of such light emitting diodes and lumiphors are readily available and are well known to those skilled in the art, and any of them can be used (eg, As a light emitting diode of 600 nm to 630 nm, AlInGaP). Examples of such light emitting diode types include inorganic and organic light emitting diodes, each of which is well known in the art.

  The one or more luminescent materials can be any desired luminescent material. The one or more luminescent materials may be downconverting, upconverting, or may include both types of bonds. For example, the one or more luminescent elements can be selected from phosphors, scintillators, daylight glow tapes, and inks that emit in the visible light spectrum when irradiated with ultraviolet light.

  The one or more luminescent materials, when provided, can be provided in any desired form. For example, the luminescent element can be embedded in a resin (ie, a polymer matrix), such as a silicone material, epoxy, or glass. Furthermore, the luminescent material can be embedded in a substantially transparent glass or metal oxide material.

  The one or more lumiphors can individually be any lumiphor, a wide variety of which are well known to those skilled in the art, as described above. For example, the or each lumiphor can consist of (or consist essentially of, or consist of) one or more phosphor emitters. The lumiphor, or each lumiphor, of the one or more lumiphors, if desired, is further, if desired, additionally, one or more highly transparent (eg, transparent or substantially transparent, Or a (somewhat scattering) binder, such as epoxy, silicone, glass, or any other suitable material (eg, in any given lumiphor consisting of one or more binders, one or more Can be dispersed in one or more binders).

  For example, the thicker the lumiphor, generally, the lower the weight percent of the phosphor phosphor. A representative example of the phosphor phosphor weight percent, as described above, includes from about 3.3 weight percent to about 4.7 weight percent, depending on the total thickness of the lumiphor, In general, it can be of any value, for example, 0.1 weight percent to 100 weight percent (eg, lumiphor formed by subjecting a pure phosphor phosphor to a thermal equilibrium pressure treatment). In some situations, a weight percent of about 20 weight percent is advantageous.

  Of the one or more lumiphors, the lumiphor or each lumiphor independently comprises any number of known additives such as diffusing agents, scattering agents, tints and the like.

  In some embodiments of the present invention, different power lines (ie, any structure that can carry electrical energy to the light emitting diodes) are electrically (directly or switchable) to different groups of light emitting diodes. The relative amount of light emitting diodes that are connected and connected to each power line varies from one power line to the next, for example, the first power line is a first percentage of 430 nm.

By doing so, the relative intensity of light at each wavelength can be easily adjusted and thereby can be navigated effectively in the chromaticity diagram and / or other Can compensate for changes. For example, the intensity of red light can be increased, if necessary, to compensate for any reduction in the intensity of light generated by light emitting diodes from 600 nm to 630 nm. Thus, for example, in the above-described typical example, the current supplied to the third power supply line is increased or supplied to the first power supply line and / or the second power supply line. Mixed light emitted by the light emitting diodes by reducing the current (and / or obstructing the supply of power to the first power line or the second power line) The x, y color coordinates of can be adjusted appropriately.
