Description

Lighting device and lighting method {LIGHTING DEVICE AND LIGHTING METHOD}

FIELD OF THE INVENTION The present invention relates to lighting devices, and more particularly to an apparatus comprising at least one solid state light emitter and at least one light emitting material (e.g., one or more phosphors). The invention also relates to an illumination method.

A large percentage of electricity produced in the United States each year (some estimates are around 25%) is used for lighting. Thus, there is a continuing need to provide more energy efficient lighting. Incandescent lamps are very energy efficient light sources, and it is well known that about 90% of the electricity consumed is emitted as heat rather than light. Fluorescent lamps are more efficient than incandescent lamps (about 10 times), but are still less efficient than solid state light emitters such as light emitting diodes.

In addition, compared to the normal life of solid state light emitters, incandescent lamps generally have a relatively short lifetime of about 750 to 1000 hours. In comparison, for example, light emitting diodes generally have a lifetime of 50,000 to 70,000 hours. Fluorescent lamps have a longer lifetime (e.g., 10000 to 20000 hours) than incandescent lamps, but provide less good color reproduction.

Color reproduction is generally measured using the Color Rendering Index (CRI). CRI Ra is a relative measure of the color rendition of the illumination system compared to the color rendering of the reference illuminator (light source). Blackbody radiators are used for color temperatures below 5000K and spectral series formed by CIE (Commission International de l'Eclairage) for color temperatures above 5000K. CRI Ra is the average value of the shift difference in the surface color of the object when illuminated by a particular lamp with respect to the surface color of the object when illuminated by the reference light source. The CRI Ra is equal to 100 if the color coordinate of the test color set illuminated by the illumination system is the same as the color coordinate of the same test color set illuminated by the reference radiator. Daylight has a high CRI (Ra is about 100), incandescent is relatively close (Ra is greater than 95), and fluorescent light is less accurate (Ra is usually 70 to 80). Certain types of special lighting have very low CRI (for example, a mercury vapor or sodium lamp has an Ra of about 40 or less). Sodium lighting is used, for example, to illuminate high speeds, but the operator response time is significantly reduced due to low CRI values (low CRI for any given brightness reduces readability).

Another problem with conventional lighting fixtures is the need to periodically replace lighting devices (eg light bulbs, etc.). Such a problem is particularly pronounced when access is difficult (eg, vaults, piers, skyscrapers, traffic tunnels) and / or when the replacement cost is extremely expensive. The typical lifetime of a typical installation is about 20 years, which corresponds to at least about 44000 hours of lighting use (based on 6 hours of use per day for 20 years). Lighting device life is generally much shorter, thus necessitating periodic replacement.

Therefore, for the above and other reasons, efforts have been made to develop a method by which light emitting diodes can be used in place of incandescent lamps, fluorescent lamps and other lighting devices in various applications. In addition, where light-emitting diodes are already in use, efforts have been made to provide light-emitting diodes with improved energy efficiency, color rendering index (CRI Ra), contrast, light efficiency (lm / W) and / or usage time, for example. It is done.

Light emitting diodes are known semiconductor devices that convert current into light. Various light emitting diodes have been used in various fields for a wide variety of purposes.

More specifically, the light emitting diode is a semiconductor device that emits light (ultraviolet light, visible light, or infrared light) when a potential difference is applied across the p-n junction structure. There are a number of known methods for making light emitting diodes and various related structures, and the present invention may employ any of such devices. Chapter 7 of Chapter 12 to Chapter 14 and Sze's "Modern Semiconductor Device Physics" (1998) of Sze's "Physics of Semiconductor Devices" (2d Ed. 1981) To describe various photonic devices.

Conventionally known and commercially available light emitting diodes ("LEDs") sold in electronic stores (for example) represent a "packaged" These packaged devices generally include semiconductor-based light emitting diodes, such as those described in US Pat. Nos. 4,918,487, 5,631,190, and 5,912,477, and a package surrounding the light emitting diodes.

As is well known, light emitting diodes generate light by exciting electrons across the bandgap between the conduction band and the valence band of the semiconductor active (light emitting) layer. The electron transition generates light of a wavelength that varies with the band gap. Therefore, 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.

The development of light emitting diodes has changed the lighting industry in many ways, but some characteristics of light emitting diodes have problems to be solved, some of which have not yet been solved. For example, the divergence spectra of any particular light emitting diode (as described in the construction and structure of the light emitting diode) are typically concentrated around a single wavelength, which is desirable for some applications, but is preferred for other applications (For example, in providing illumination, such a divergence spectrum provides a very low CRI).

Since the light perceived as white is basically a mixture of two or more colors (or wavelengths), a single light emitting diode conjugate that generates white light has not been developed. "White" light-emitting diodes having light-emitting diode pixels formed of red, green and blue light emitting diodes are being produced. (1) a light emitting diode that generates blue light, (2) a light emitting material (for example, a phosphor) that emits yellow light in response to excitation by light emitted by the light emitting diode, Other "white" light emitting diodes that produce light perceived as white light are being produced.

Also, blending primary colors to create combinations of colors that are not primary is generally well understood in this and other techniques. In general, the 1931 CIE Chromaticity Diagram (international standard for primary colors established in 1931) and the 1976 CIE chromaticity diagram (similar to the 1931 chromaticity diagram, but similar distances on the diagram are modified to represent similar perceptual color differences) Provides a useful criterion for color formation as a weighted sum of the primary colors.

Thus, the light emitting diodes may be used individually or in any combination, and may optionally include one or more luminescent materials (e.g., phosphors or scintillators) to generate light of any desired perceived hue (including white) ] And / or filters. Thus, for example, areas where efforts to replace existing light sources with light emitting diode light sources to improve energy efficiency, CRI, light efficiency (lm / W), and / It is not limited to color mixing.

Various luminescent materials, also known as "lumiphors" or "luminophoric" as disclosed in US Pat. No. 6,600,175, which is incorporated herein by reference, are known and are commercially available to those skilled in the art . For example, the phosphor is a luminescent material that emits a reaction radiation (for example, visible light) when excited by an excitation radiation source. In many instances, the response radiation has a different wavelength than the wavelength of the excitation radiation. Other examples of the light emitting material include a scintillator, a day glow tape that emits light in the visible spectrum upon irradiation with ultraviolet light, and an ink.

The luminescent material can be classified as down conversion, that is, a material that converts a photon to a lower energy level (longer wavelength) or a material that up-converts, that is, a material that converts a photon to a higher energy level (shorter wavelength).

Including the light emitting material in the LED device can be achieved by adding the light emitting material to the aforementioned transparent or translucent encapsulant material (e.g., epoxy, silicone, or glass-based material), for example, by a mixing or coating process .

For example, U.S. Patent No. 6,963,166 (Yano) '166 discloses a conventional light emitting diode lamp that includes a light emitting diode chip, a bullet-shaped translucent housing for covering the light emitting diode chip, a lead for supplying current to the light emitting diode chip, And a cup reflector for reflecting the divergence of the light emitting diode chip in a uniform direction, wherein the light emitting diode chip is surrounded by the first resin portion and is surrounded by the second resin portion. According to YANO '166, the first resin portion is obtained by filling the cup reflector with a resin material and electrically connecting the cathode and anode to the lead by wire after the light emitting diode chip is mounted on the bottom of the cup reflector and then curing . According to YANO '166, a phosphor is scattered in the first resin portion and is excited by light (A) emitted from the light emitting diode chip, and the excited phosphor emits fluorescence having a longer wavelength than light (A) ), And a part of the light A is transmitted through the first resin part including the phosphor, and as a result, the light C mixed with the light A and the light B is used as illumination.

As described above, "white LED light" (ie, light perceived as white or nearly white) has been investigated as a potential alternative to white incandescent lamps. Representative examples of white LED lamps include a package of blue light emitting diode chips made of indium gallium nitride (InGaN) or gallium nitride (GaN) coated with a phosphor such as YAG. In such an LED lamp, the blue light emitting diode chip emits at a wavelength of about 450 nm, and the phosphor emits yellow fluorescence having a peak wavelength of about 550 nm. For example, in some designs, a white light emitting diode is fabricated by forming a ceramic phosphor layer on the output surface of a blue light emitting semiconductor light emitting diode. A portion of the blue light emitted from the light emitting diode chip passes through the phosphor while a portion of the blue light emitted as the light emitting diode chip is absorbed by the phosphor and the phosphor is excited to emit yellow light. A portion of the blue light emitted from the light emitting diode is transmitted through the phosphor and mixed with the yellow light emitted by the phosphor. The observer perceives the mixed light of blue light and yellow light as white light.

Also as described above, in other types of LED lamps, light emitting diodes that emit ultraviolet light are combined with phosphor materials that emit red (R), green (G) and blue (B) rays. In such a "RGB LED lamp ", ultraviolet radiation emitted from a light emitting diode chip excites the phosphor, causing the phosphor to emit red, green and blue light rays, which are perceived as white light in the human eye when mixed. As a result, white light can also be obtained as mixed light of these rays.

Designs have been provided in which existing LED component packages and other electronic components are assembled in a facility. In such a design, the packaged LED is mounted directly to the circuit board or heat sink, the circuit board is mounted to the heat sink, and the heat sink is mounted to the facility housing along with the required drive electronics. In many cases, additional optical parts (secondary to the packaged parts) are also needed.

For example, when replacing another light source, such as an incandescent lamp, with a light emitting diode, the packaged LED may include a base plate attached to, for example, a hollow lens and a lens, and the base plate may comprise one or more Has been used with conventional lighting equipment such as equipment with a conventional socket housing with contacts. For example, the LED bulb includes an electrical circuit board, a plurality of packaged LEDs mounted on a circuit board, and a connection post attached to the circuit board and configured to connect to the socket housing of the lighting fixture, Lt; / RTI >

In order to provide white light for various applications with greater energy efficiency, improved color rendering index (CRI), improved light efficiency (lm / W), lower cost and / or longer usage time, There is a continuing need for a method of using a light emitter.

There is a "white" LED light source that is relatively efficient, but generally has a CRI Ra value of less than 75, resulting in a lack of color representation, especially a lack of red representation and a significant lack of green representation. This means that many things, including the faces of ordinary people, food, labeling, paintings, posters, signage, clothing, home decorations, plants, flowers, cars, etc., display strange or erroneous colors compared to being illuminated by incandescent or natural daylight . In general, such a white LED has a color temperature of about 5000K, which is generally not visually comfortable with general purpose lighting, but may be desirable for commercial presentation or advertising and lighting of printed matter.

The so-called "warm white" LED has a better color temperature (typically 2700K to 3500K) for indoor use and a good CRI for some special cases (yellow and red phosphor blend, Is much lower than the efficiency of a "cool white" LED.

Colored objects illuminated by RGB LEDs often do not appear as real colors. For example, an object that reflects only yellow light and therefore appears to be yellow when illuminated with white light may appear gray when illuminated with light of a distinct yellow color generated by the red and green LEDs of the RGB LED setup. Thus, such lamps are considered not to provide excellent color rendering properties, particularly when illuminating various settings, such as in general purpose lighting, and in particular with respect to natural landscapes. Also, currently available green LEDs are relatively inefficient and thus limit the efficiency of such lamps.

The use of LEDs with diverse hues also necessitates the use of LEDs of various efficiencies, including several LEDs with low efficiency, thus reducing the efficiency of such systems, controlling various types of LEDs, Which greatly increases the complexity and cost of the circuitry for maintaining < RTI ID = 0.0 >

Thus, there is a need for a high efficiency white light source that combines the efficiency and long lifetime of a white LED (i.e., avoiding the use of relatively inefficient light sources) with satisfactory color temperature and good color rendering index, wide gamut and simple control circuitry.

According to the present invention, (1) light emitted from one or more light emitting diodes emitting light having a peak wavelength in the range of 430 nm to 480 nm, and (2) light emitting light having a dominant wavelength in the range of 555 nm to 585 nm. Surprisingly high CRI can be obtained by combining light emitted from one or more lumiphors, and (3) light emitted from one or more light emitting diodes emitting light having a dominant wavelength in the range of 600 nm to 630 nm. Was discovered by chance.

Particularly high CRI is such that when each of the first group of LED groups is illuminated and each of the first groups of lumiphores is excited, there is no additional light in the mixed light of the light emitted from the first group of LED groups and the first group of lumiphores Obtained when the light-emitting diode and the lumiphor are selected to have a first group mixed illumination with x, y color coordinates in an area on the 1931 CIE chromaticity diagram surrounded by first, second, third, fourth and fifth line segments. Wherein the first line segment connects the first point to the second point, the second line segment connects the second point to the third point, and the third line segment connects the third point to the fourth 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, The second point has x, y coordinates of 0.36, 0.48, and the third point has x, y of 0.43, 0.45 The fourth point has the x, y coordinates of 0.42, 0.42, and the fifth point has the x, y coordinates of 0.36, 0.38.

In one aspect of the invention, the light emitting diodes and the lumiphors have a mixed light of light emitted from the first light emitting diode group, the first light emitting group, and the second light emitting diode group having about 2200K on the blackbody trajectory on the 1931 CIE chromaticity diagram. With x, y coordinates on a 1931 CIE chromaticity diagram that forms a point that is within 10 MacAdam ellipse (or within 20 MacAdam ellipses or within 40 MacAdam ellipses) of at least one point in the range from about 4500K. The light emitting diodes and the lumiphors are selected to form a first group-second group mixed illumination.

In addition, in particular, the above-mentioned light 2 (ie, light emitted from one or more lumiphors emitting light having a dominant wavelength in the range of 555 nm to 585 nm) is emitted from a broad spectrum light source such as, for example, a yellow lumiphor. In the case, it has been found by chance that surprisingly high CRI can be obtained by combining the above-described light.

Light from at least one lumiphor is provided with an illumination method each having a dominant wavelength in the range of 555 nm to 585 nm.

According to the twenty first aspect of the present invention,

Capsule element,

A light emitting diode that, when illuminated, emits light having a peak wavelength in the range of 430 nm to 480 nm;

Includes a lumiphor, when illuminated, that emits light having a dominant wavelength in the range of 555 nm to 585 nm,

Light-emitting diodes and lumiphors are embedded in the capsule element,

The third point has a x, y coordinate of 0.43, 0.45, the fourth point is 0.42 , X, y coordinates of 0.42, and the fifth point has x, y coordinates of 0.36, 0.38.

The light emitting diode may or may not be saturated. The term "saturated" means herein at least 85% purity, the term "purity" has a meaning well known to those skilled in the art, and the process of calculating purity is well known to those skilled in the art.

Aspects associated with the present invention may be displayed on a 1931 CIE chromaticity diagram or a 1976 CIE chromaticity diagram. 1 shows a 1931 CIE chromaticity diagram. 2 shows a 1976 chromaticity diagram. 3 is an enlarged view of a portion of a 1976 chromaticity diagram to further illustrate the blackbody trajectory. Those skilled in the art are familiar with these diagrams, which are readily available (for example, by searching for "CIE chromaticity diagram" on the Internet).

The CIE Chromaticity Diagram accurately represents human color perception with two CIE parameters: x and y (for the 1931 chromaticity diagram) or u 'and v' (for the 1976 chromaticity diagram). For a technical description of the CIE chromaticity diagram, see, for example, "Encyclopedia of Physical Science and Technology" (vol. 7, 230-231, Robert A Meyers ed. 1987). The spectral colors are distributed around the edge of the contoured space, which includes all the hues perceived by the human eye. The border represents the maximum saturation of the spectral color. As noted above, the 1976 CIE Chromaticity Diagram is similar to the 1931 diagram, except that similar distances on the diagram have been modified to represent similar perceptual color differences.

In the 1931 diagram, the deviation from a point on the diagram may be expressed in terms of coordinates or, alternatively, as a McAdam ellipse to provide an indication regarding the degree of perceived color difference. For example, the trajectories of the points formed by 10 McAdam ellipses from a specified hue formed by a particular set of coordinates on the 1931 plot consist of hue that can each be perceived to be different from the particular hue to a common degree. The same is true for the trajectories of points formed by positive McAdam ellipses spaced from a particular hue).

Since similar distances on the 1976 plot represent similar perceptual color differences, the deviation from a point on the 1976 plot can be represented by coordinates u 'and v', for example, distance from the point = (Δu ' ² + Δv). ' ² ) ^1/2 , the tones formed by the trajectories of points at a common distance from the specified hue respectively consist of hue that is perceived to be different from the hue specified in common degree.

The chromaticity coordinates and CIE chromaticity diagrams shown in FIGS. 1-3 are shown in pages 98-107 of "Fluorescent Lamp Phosphors" (KH Butler, The Pennsylvania State University Press 1980) and "Luminescent Materials" (Blasse et al.). , Spring-Verlag 1994), which are described in detail in a number of books and other publications.

를 따르며, 여기서 E는 발산 강도이고, λ는 발산 파장이며, T는 흑체의 색온도이고, A 및 B는 상수이다. 흑체 궤적 상에 또는 그 근처에 놓인 색좌표는 관찰자에게 만족스러운 백색광을 제공한다. 1976 CIE 도표는 흑체 궤적을 따라 온도 목록을 포함한다. 이들 온도 목록은 그러한 온도를 증가하게 하는 흑체 복사체의 색 경로를 도시한다. 가열된 물체는 백열광을 낼 때, 먼저 적색으로 빛나고, 다음으로 황색으로 빛나며, 그리고 백색으로 빛나고, 마지막으로 청색으로 빛난다. 이것은 흑체 복사체의 피크 복사열과 관련된 파장이 증가된 온도에서 급격히 짧아지기 때문이며, 이는 빈의 변위 법칙(Wien's Displacement Law)와 일치한다. 따라서 흑체 궤적 상에 또는 그 근처에 있는 광을 발생시키는 발광체는 색온도로 설명될 수 있다.The chromaticity coordinates (ie color points) along the blackbody trajectory are Planck's equations:

Where E is the divergence intensity, λ is the divergence wavelength, T is the color temperature of the blackbody, and A and B are constants. Color coordinates lying on or near the blackbody trajectory provide the viewer with satisfactory white light. The 1976 CIE chart includes a list of temperatures along the blackbody trajectory. These temperature lists show the color path of the blackbody radiation causing such temperatures to increase. When heated, it glows red first, then yellow, then white, and finally blue. This is because the wavelength associated with the peak radiant heat of the blackbody radiator becomes shorter at increased temperatures, which is consistent with Wien's Displacement Law. Thus, a light emitter that generates light on or near the blackbody trajectory can be described as a color temperature.

In the 1976 CIE diagram, the symbols A, B, C, D and E are indicated which indicate the light generated by several standard illuminants, respectively identified as illuminants A, B, C, D and E.

CRI Ra is a modified average of the relative measurements of the color rendering of the illumination system compared to the reference radiation when illuminating the eight reference colors. CRI Ra is equal to 100 when the color coordinates of the test color set illuminated by the illumination system are the same as the coordinates of the same test color illuminated by the blackbody copy.

The well-known meaning of the term "correlated color temperature" is used to refer to the temperature of the closest black body in terms of color in the sense that it is clear (i.e., readily determinable by one skilled in the art).

The expression "directly or switchably electrically connected" means "directly electrically connected" or "switchably electrically connected ".

The expression “directly electrically connected” in the two components in the device herein means that there is no electrical component between the components that substantially affects the function or functions provided by the device. . For example, it can be said that the two components are electrically connected even though they have a small resistance between them, which does not substantially affect the function or functions provided by the device (actually, the wires connecting the two components May be thought of as a small resistor). Likewise, the two components may be further electrically and mechanically coupled, such that they do not substantially affect the functionality or functions provided by the same device, except that they do not include additional components, It can be said that they are electrically connected even if they have components between them. Likewise, the two components that are directly connected to each other or directly connected to both ends of the trace on the wire or circuit board are electrically connected.

The expression "switchably electrically connected" in the present application means that there are switches located between the two components, the switches are selectively closed or open, and when the switch is closed two Means that the components are directly electrically connected and that the two components are not electrically connected when the switch is opened (i.e., during any time the switch is open).

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 so that the light emitting diode emits at least some light. The expression "lighted" refers to a situation in which a light emitting diode emits light continuously, or a situation in which light emits intermittently enough to be perceived by the human eye as a continuous light emission, or continuously emits light (and when different colors are emitted). Is a situation where a plurality of light emitting diodes having the same or different colors, such as a mixture of these colors), emits light intermittently and / or alternately (with or without overlap of time "on") to the human eye's perception. It includes.

The term "excited " as used herein when referring to a lumipper is intended to mean that at least some of the electromagnetic radiation (e.g., visible, ultraviolet or infrared) is in contact with the lumiphor such that the lumiphor emits at least some light . The expression "excited" is intended to encompass a situation in which a luminifer is continuously emitting, or a situation in which the light is intermittently emitted to the extent that the human eye perceives it to be continuously emitting, or continuously emitting (and, (With a mixture of these colors) of a plurality of lumiphores of the same color or different colors perceived by the human eye, intermittently and / or alternately emitting light (with or without overlapping of the "on" time) do.

The light emitting diodes (or light emitting diodes) used in the apparatus according to the invention and the luminaires (or luminaires) used in the apparatus according to the invention may be selected from any light emitting diode or luminaires known to those skilled in the art. A variety of light emitting diodes and luminaires are readily available and known to those skilled in the art, and any of them can be employed (e.g., AlInGaP for 600 nm to 630 nm light emitting diodes).

Examples of such types of light emitting diodes include inorganic and organic light emitting diodes, each of which is known in the art.

The at least one luminescent material may be any desired luminescent material. The one or more luminescent materials may be downconverted or upconverted, or may comprise a combination of both types. For example, the at least one light emitting material may be selected from a phosphor, a scintillator, a dayglass tape shining with a visible spectrum upon irradiation of ultraviolet rays, and an ink.

One or more luminescent materials may be provided in any desired form. For example, the light emitting element may be embedded in a resin such as a silicone material or epoxy (i.e., a polymer matrix). Further, the light emitting material may be embedded in a substantially transparent glass or metal oxide material.

The one or more lumipers may each be any of the various lumippers known to those skilled in the art, as described above. For example, each of the luminaires may comprise one or more phosphors (or may consist of or consist essentially of one or more phosphors). One or more lumiphor can further comprise one or more highly transparent (e.g., transparent or substantially transparent or somewhat diffusible) binders made of, for example, epoxy, silicone, glass or any other suitable material (E.g., in any given luminifer, including one or more binders, one or more phosphors may be scattered within one or more binders). For example, the thicker the lumiphor, the lower the weight percent of the phosphor may be. Representative examples of the weight percent of the phosphor include from about 3.3 weight percent to about 4.7 weight percent, but as described above, depending on the overall thickness of the lumiphore, generally the weight percent of the phosphor is for example from 0.1 weight percent to 100 weight percent It can be any value up to% (for example, a lumiphor formed by treating a pure phosphor by a high temperature isostatic molding process). In some situations, about 20% by weight is advantageous.

The one or more lumipers may each independently further comprise any of a number of well known additives such as, for example, diffusers, dispersants, tints, and the like.

In some embodiments of the present invention, different power lines (i.e., any structure capable of delivering electrical energy to the light emitting diode) can be electrically connected (directly or switchably) to different groups of light emitting diodes, The amount of the light-emitting diodes connected to each other is different between the power lines. For example, the first power line includes a first rate of 430 to 480 nm light emitting diodes, and the second power line includes a second rate (different from the first percentage) of 430 to 480 nm light emitting diodes. As a representative example, the first and second power lines each comprise 100% of 430 nm to 480 nm light emitting diodes, respectively, and the third power line comprises 50% of 430 nm to 480 nm light emitting diodes and 50% of 600 nm to 630 nm. It includes a light emitting diode. By doing so, it is possible to easily adjust the relative intensities of the light of the respective wavelengths, and it is therefore possible to find the path effectively and / or compensate for other changes within the CIE chromaticity diagram. For example, the intensity of the red light may be increased when necessary to compensate for any reduction in the intensity of light generated by the 600 nm to 630 nm light emitting diodes. Thus, for example, in the representative example described above, by increasing the current supplied to the third power line, or by reducing the current supplied to the first power line and / or the second power line (and / or the first power line or the second By blocking the power supply to the power line), the x, y coordinates of the mixed light emitted from the lighting device can be adjusted appropriately.
