Technical field of composition for LED light conversion

[0001] The present disclosure is in the field of solid-state lighting. Specifically, the present disclosure relates to a luminophor composition for a method of generating white light.

Background technique

[0002] Various light emitting devices are known in the art, including, for example, incandescent bulbs, fluorescent lamps, and semiconductor light emitting devices such as light emitting diodes ("LEDs").

[0003] There are various resources for describing the light generated by the light-emitting device, and a commonly used resource is the 1931 CIE (International Commission on Illumination) chromaticity diagram. The 1931 CIE chromaticity diagram draws human color perception based on two CIE parameters X and y. The spectral colors are distributed around the edges of the depicted space and include all the cues that the human eye perceives. The boundary line represents the maximum saturation of the spectral color, and the inner part represents the less saturated color including white light. The figure also depicts the Planck locus with correlated color temperature, also known as the black body locus (BBL), which represents the chromaticity coordinates (ie, color points) corresponding to radiation from the black body at different temperatures. Therefore, the luminous bodies that generate light on or near the BBL can be described in terms of their correlated color temperature (CCT). These luminous bodies enable human observers to obtain pleasant "white light", and general lighting usually utilizes CCT values between 1,800K and 10,000K.

[0004] The color rendering index (CRI) is described as an indication of the vibration of the color of light generated by a light source. In practice, CRI is a relative measure of the color shift of an object's surface when it is lit by a specific lamp when compared to a reference light source-usually a blackbody radiator or sunlight spectrum. The higher the CRI value of a particular light source, the better the color of various objects that the light source uses to illuminate it.

[0005] Compared to conventional incandescent lamps or fluorescent lamps, LEDs have the potential to exhibit very high power efficiency. Most LEDs are basically monochromatic light sources, which seem to emit light with a single color. Therefore, the spectral power distribution of the light emitted by most of the LEDs is tightly concentrated around the "peak" wavelength. The "peak" wavelength is a single wavelength, where the spectral power distribution or "emission spectrum" of the LED reaches the value detected by the photodetector. Maximum value. LEDs generally have a half-height wavelength range of about 10 nm to 30 nm, which is quite narrow compared to the wide range of visible light of the human eye, which ranges from about 380 nm to 800 nm.

[0006] In order to generate white light using LEDs, LED lamps including two or more LEDs have been provided, each LED emitting light of a different color. Different colors are combined to produce white light of the desired intensity and/or color. For example, by energizing red, green, and blue LEDs at the same time, the resulting combined light can appear white or nearly white, depending on, for example, the relative intensity, peak wavelength, and spectral power distribution of the red, green, and blue LED sources. Due to gaps in the spectral power distribution in regions away from the peak wavelength of the LEDs, the aggregate emission from red, green, and blue LEDs generally provides poor CRI for general lighting applications.

[0007] White light can also be generated by using one or more luminescent materials, such as phosphors, to convert some of the light emitted by one or more LEDs into one or more other colors of light. The combination of the light emitted by the LED that is not converted by the luminescent material(s) and the light of other colors emitted by the luminescent material(s) can produce white light or near-white light.

[0008] LED lamps have been provided that can emit white light with different CCT values within a certain range. This kind of lamp uses two or more LEDs with or without luminescent materials, and the respective drive current increases or decreases so that each LED emits

The amount of light increases or decreases. By controllably changing the power of each LED in the lamp, the total light emitted can be tuned to different CCT values. The range of CCT values that can provide sufficient CRI value and efficiency is limited by the selection of LEDs.

[0009] The spectral profile of light emitted by white artificial lighting may affect circadian physiology, alertness, and cognitive performance levels. Bright artificial light can be used in many therapeutic applications, such as in seasonal affective disorder (SAD), certain sleep problems, depression, jet lag, sleep disorders in Parkinsons disease, health consequences associated with shifts, and the weight of the bodys biological clock. Centered treatment. Artificial lighting may alter natural processes, interfere with melatonin production, or disrupt the circadian rhythm. Blue light may have a greater tendency than other colored lights to affect organisms by disrupting biological processes that may depend on the natural cycles of sunlight and darkness. Therefore, exposure to blue light in the middle of the night and at night may be harmful to human health.

[0010] There are still major challenges in providing LED lamps that can provide white light across the range of CCT values while achieving high efficiency, high luminous flux, good color rendering and acceptable color stability. It is also a challenge to provide lighting devices that can provide desired lighting performance while allowing control of day and night energy performance.

[0011] Therefore, there is an urgent need to provide a composition for converting the light generated by the LED into white light having desired spectral characteristics.

Detailed ways

[0025] Light-emitting diode (LED) lighting has a number of advantages over incandescent to fluorescent lighting. Advantages include long life, low energy consumption and small size. White light is generated by a combination of LEDs using phosphors to convert the wavelength of light generated by the LED into a pre-selected wavelength or wavelength range.

[0026] In one aspect, the present disclosure provides a semiconductor light emitting device 100 that may have multiple light emitting diode (LED) strings. Each LED string can have one or more than one LED. As schematically depicted in Figure 1, the device 100 may include one or more LED strings (101A/101B/101C/101D) that emit light (shown schematically by arrows). In some cases

Below, the LED string can have an acceptor luminophor medium (102A/102B/102C/102D) associated with it. The light emitted from the LED string combined with the light emitted from the acceptor luminophor medium may pass through one or more optical elements 103. The optical element 103 may be one or more diffusers, lenses, light pipes, reflective elements, or combinations thereof.

[0027] The acceptor luminophore medium 102A, 102B, 102C, or 102D includes one or more luminescent materials and is positioned to receive light emitted by an LED or other semiconductor light emitting device. In some implementations, the acceptor luminophore medium includes a layer with a luminescent material that is directly coated or sprayed onto the semiconductor light-emitting device or its encapsulated surface, and a transparent sealing material that includes the luminescent material, and the luminescent material is arranged To partially or completely cover the semiconductor light emitting device. The acceptor luminophore medium may include a medium layer or similar layer in which one or more luminescent materials are mixed, a plurality of stacked layers or media, each of which may include one or more of the same or different luminescent materials, and /Or multiple spaced apart layers or media, each of which may include the same or different luminescent materials. Suitable sealing materials are known to those skilled in the art and have suitable optical, mechanical, chemical and thermal characteristics. In some implementations, the sealing material may include dimethyl silicone, phenyl silicone, epoxy, acrylic, and polycarbonate. In some implementations, the acceptor luminophore medium may be spatially separated from the surface of the LED or its package (ie, located remotely), where the luminescent material is arranged within the matrix material. The matrix material may be any material that can hold the luminescent material and can allow light to pass through it. In some implementations, this spatial separation Separation may involve separation by a distance of at least about 1 mm, at least about 2 mm, at least about 5 mm, or at least about 10 mm. In certain embodiments, the electrically conductive thermal communication between the spatially isolated luminophore medium and the one or more electrically activated emitters is not significant. The luminescent material may include phosphors, scintillators, solar ribbons, nano-phosphors, inks that emit light in the visible spectrum when irradiated with light, semiconductor quantum dots, or combinations thereof.

[0028] As schematically depicted in FIG. 2, a plurality of solid-state packages 200 may be arranged in a single semiconductor light emitting device 100. Individual solid-state emitter packages or groups of solid-state emitter packages can be controlled individually (for example, serial wiring). The drive current can be independently applied to the relevant components through control elements known to those skilled in the art to provide individual control of a single transmitter, a group of transmitters, a single package, or a group of packages. In one embodiment, the at least one control circuit 201a may include a current supply circuit configured to independently apply the path state drive current to a single solid-state emitter, a group of solid-state emitters, a single solid-state emitter package, or a group of solid-state emitters. Each of the solid-state emitter packages. Such control may be responsive to a control signal (optionally including at least one sensor 202 arranged to sense electrical, optical, and/or thermal properties and/or environmental conditions), and the control system 203 may be configured to selectively provide a Or multiple control signals to at least one current supply circuit. In various embodiments, the currents to different circuits or circuit parts may be preset, user-defined, or in response to one or more inputs or other control parameters. The design and manufacture of semiconductor light emitting devices are well known to those skilled in the art, and therefore, further description thereof will be omitted.

[0029] Figure 3 illustrates the 1931 International Commission on Illumination (CIE) chromaticity diagram. The 1931 CIE chromaticity diagram is a two-dimensional chromaticity space, in which each visible color is represented by a point with x- and y-coordinates. Fully saturated (monochrome) colors appear on the outer edges of the chart, while less saturated colors (which represent combinations of wavelengths) appear inside the chart. As used herein, the term "saturated" means having a purity of at least 85%, the term "purity" has a meaning well known to those skilled in the art, and the procedure for calculating purity is well known to those skilled in the art. As the temperature of the blackbody changes from about 1000K to 10,000K, the Planck locus or blackbody locus (BBL) represented by the line 150 in the graph follows the color taken by the incandescent blackbody in the chromaticity space. The black body locus changes from deep red at low temperatures (about 1000K) to orange, yellowish white, white, and finally light blue-white at very high temperatures. The temperature of a black body radiator corresponding to a specific color in the chromaticity space is called "correlated color temperature". Generally speaking, light corresponding to a correlated color temperature (CCT) of about 2700K to about 6500K is considered "white" light. Specifically, as used herein, "white light" generally refers to light having a chromaticity point that is between 2700K and 6500K in CCT.

Inside the 10-order McAdam ellipse of the point on the blackbody locus. However, it should be understood that a stricter or looser definition of white light can be used if desired. For example, white light may refer to light having a chromaticity point that is within a 7th-order MacAdam ellipse with a CCT of a point on the blackbody locus between 2700K and 6500K. The distance to the black body locus can be measured in the CIE 1960 chromaticity diagram, and the symbol A_UVOr DUV instructions. If the chromaticity point is higher than the Planck locus, DUV is indicated by a positive number; if the chromaticity point is lower than the locus, DUV is indicated by a negative number. If the DUV is sufficiently positive, the light source can appear light green or light yellow under the same CCT. If the DUV is sufficiently negative, the light source can appear purple or pink under the same CCT. For specific CCT values, observers may prefer light above or below Planck's locus. The DUV calculation method is well-known to those skilled in the art, and is described in ANSI C78.377, American National Standard for Electric Lamps-Spec ifi cat i ons for the solid-state lighting (SSL) product It is described more fully in Chromaticity of Solid State Lighting (SSL) Products), which is incorporated herein by reference in its entirety for all purposes. The point representing the CIE standard illuminator D65 is also shown in the graph. The D65 illuminator is intended to represent average daylight and has a CCT of about 6500K, and the spectrum is more fully described in the joint ISO/CIE standard for colorimetry, ISO 10526:1999/CIE S005/E_1998, CIE standard illuminant Power distribution, out of all For the purpose, it is incorporated herein by reference in its entirety.

[0030] The light emitted by the light source can be represented by a point on a chromaticity diagram such as the 1931 CIE chromaticity diagram, which has color coordinates indicated on the XY axis of the graph (_CCX，_CCy). The areas on the chromaticity diagram can represent light sources with similar chromaticity coordinates. [0031] In some exemplary implementations, the present disclosure provides a semiconductor light emitting device 100 including a plurality of LED strings, each LED string having an acceptor luminophore medium including a luminescent material. The LEDs (one or more) in each string and the luminous medium in each string emit unsaturated light together, the unsaturated light having a color point within the color range of the 1931 CIE chromaticity diagram. The "color range" in the 1931 CIE chromaticity diagram refers to a set of color coordinates (_CCX，_CCy) the bounded area.

[0032] In some implementations, four LED strings (101A/101B/101C/101D) are present in the device 100, and the LED strings may have an acceptor luminophor medium (102A/102B/102C/102D). The first LED string 101A and the first luminous body medium 102A may together emit the first light having the first color point in the blue range. The combination of the first LED string 101A and the first luminous body medium 102A is also referred to herein as the "blue channel". The second LED string 101B and the second luminous body medium 102B may together emit second light having a second color point in the red range. The combination of the second LED string 101A and the second luminous body medium 102A is also referred to herein as the "red channel". The third LED string 101C and the third luminous body medium 102C may together emit third light having a third color point in the yellow/green range. The combination of the third LED string 101A and the third luminous body medium 102A is also referred to herein as the "yellow/green channel". The fourth LED string 101D and the fourth luminous body medium 102D may together emit fourth light having a fourth color point in the cyan range. The combination of the fourth LED string 101A and the fourth luminous body medium 102A is also referred to herein as the "cyan channel". The first, second, third and fourth LED strings 101A/101B/101C/101D can be provided with independently applied The on-state drives current to adjust together the intensities of the first, second, third, and fourth unsaturated light generated by each string and the luminous body medium. By changing the driving current in a controlled manner, the color coordinates of the total light emitted from the device 100 can be adjusted (_CCx,_CCy). In some implementations, the device 100 can provide lights with different spectral power distribution curves at substantially the same color coordinates, which can produce different light characteristics at the same CCT. In some implementations, white light can be generated in a mode that only generates light from two or three LED strings. In one implementation, only the first, second and third LED strings, namely the blue, red, and yellow/green channels are used to produce white light. In another implementation, only the first, second and fourth LED strings, namely the blue, red and cyan channels are used to generate white light. In some implementations, only two LED strings generate light during white light generation, so the other two LED strings do not need to generate white light with the desired color rendering performance at the desired color point.

[0033] Figures 4A, 4B, 4C, and 4D depict suitable color ranges for some implementations of the present disclosure. Figure 4A depicts the green

Color range 304A, the cyan range consists of the line connecting the ccx and ccy color coordinates (0.18, 0.55) and (0.27, 0.72), the CCT isotherm of 9000K, the Planckian locus between 9000K and 4600K, and the CCT isotherm of 4600K , And the spectral trajectory limit. Figure 4B depicts the yellow/green range 303A, which consists of the CCT isotherm of 4600K, the Planckian trajectory between 4600K and 550K, the spectral trajectory and the connection ccx, ccy color coordinates (0.445, 0.555) and (0.38 , 0.505) of the line limit. Figure 4C depicts the blue range 301A, which is composed of the ccx and ccy color coordinates (0.242, 0.24) and Φ connecting the infinite points of the Planckian locus. 12, 0.068), Planck trajectory from 4000K and infinite CCT, CCT isotherm, purple line and spectral trajectory definition. Figure 4D depicts the red range 302A, which consists of the spectral locus between the 1600K CCT isotherm and the purple line, the purple line, the line connecting the ccx, ccy color coordinates (0.61, 0.21) and (0.47, 0.28) and 1600K The CCT isotherm is limited. It should be understood that any gaps or openings at the boundaries of the described color ranges 301", 302", 303", and 304" should be closed with straight lines to connect adjacent end points, so as to define the closed boundary of each color range.

[0034] In some implementations, suitable color ranges may be narrower than those depicted in FIGS. 4A-4D. Figure 5 depicts some suitable color ranges for some implementations of the present disclosure. The blue range 301B can be defined by the 60-order McAdam ellipse at the CCT of 20000K, which is lower than 40 points of the Planckian trajectory. The red range 302B can be defined by the 20-order MacAdam ellipse at the CCT of 1200K, which is 20 points lower than the Planck trajectory. The yellow/green range 303B can be defined by the 16-order McAdam ellipse at the CCT of 3700K, which is 30 points higher than the Planck trajectory. The cyan range 304B can be defined by the 30-order MacAdam ellipse at the 6000K CCT, which is higher than the 68 points of the Planck trajectory. Figure 6 depicts some further color ranges suitable for some implementations of the present disclosure: blue range 301C, red range 302C, yellow/green color range 303C, and cyan color range 304C.

[0035] In some implementations, the LEDs in the first, second, third, and fourth LED strings may be LEDs having a peak emission wavelength at or below about 535 nm. In some implementations, the LED emits light having a peak emission wavelength between about 360 nm and about 535 nm. In some implementations, the LEDs in the first, second, third, and fourth LED strings may be formed of a sand-based semiconductor material. In some preferred implementations, the first, second, and third LED strings may have LEDs having a peak wavelength between about 405 nm and about 485 nm. In some implementations, the fourth LED string may have an LED having a peak wavelength between about 485 nm and about 520 nm. The LEDs used for the first, second, third, and fourth LED strings may have a half-height wide wavelength range between about 10 nm and about 30 nm. In some preferred implementations, the first, second, and third LED strings may include color identification codes (bin(30(16)3, 4, 5, or 6 of one or more 1^^£(^2 Color Line Royal blue LEDs (product code LXZ1-PR01) or one or more LUXEON Z Color Line blue LEDs (LXZ1-PB01) with color identification code 1 or 2 (Lumileds, Amsterdam, Netherlands Holding BV). In some preferred implementations, the fourth LED string may have one or more LUXEON Z Color Line blue LEDs (LXZ1-PB01) with the color identification code 5 or one of the color identification codes 1, 2, 6, 7, 8 or 9. Or multiple LUXEON Z Color Line cyan LEDs (LXZ1-PE01) (Lumileds Holding BV, Amsterdam, Netherlands). The wavelength information of these colors BIM is provided in the table of FIG. 9. It is also possible to use similar LEDs from other manufacturers such as OSRAM GmbH and Cree, Inc., as long as they have suitable values of peak emission and half-width wavelengths.

[0036] In an implementation that utilizes LEDs that emit substantially saturated light with a wavelength between about 360 nm and about 535 nm, the device 100 may include a suitable acceptor luminophor medium for each LED in order to produce The suitable blue range 301A-C, red range 302A-C, yellow/green range 303A-C and cyan range 304A-C are within the color point of light. The light emitted by each LED string, that is, the light emitted by the LED (one or more) and the relevant acceptor luminophore medium, together may have a spectral power distribution ("SPD"), the power ratio of which is across From about 380nm to about 780nm in the visible wavelength spectrum. Although not wishing to be bound by any specific theory, it is speculated that the combination of this LED and the acceptor luminophore medium is used to

Unsaturated light generated in the appropriate color ranges 301A-C, 302A-C, 303A-C, and 304A-C provides improved color rendering performance for white light from a single device 100 that crosses the predetermined range of the CCT. Some suitable ranges of the spectral power distribution ratio of the light emitted by the four LED strings (101A/101B/101C/101D) and the acceptor luminophor medium (102A/102B/102C/102D) are shown together in Figures 7 and 8. . The figure shows the ratio of the spectral power in the wavelength range, where an arbitrary reference wavelength range is selected for each color range and normalized to a value of 100.0. Figures 7 and 8 show suitable minimum values of the spectral intensities of various ranges within a standardized range relative to a value of 100.0 for color points in the blue, cyan, yellow/green ("yag") and red ranges And the maximum value. Although not wishing to be bound by any specific theory, it is presumed that the spectral power distribution of light with color points in the blue, cyan, and yellow/green ranges produced compared to lighting devices and methods that use more saturated colors Contains higher spectral intensity across visible wavelengths, which allows for improved color rendering.

[0037] When excited by their respective LED strings (101A/101B/101C/101D), blends of luminescent materials can be used in the luminescent medium (102A/102B/102C/102D) to produce a desired saturated color point The luminous medium. Traditionally, any desired combined output light can be produced along the line between the color point of the LED string output light and the saturated color point of the associated receptor luminophore medium. Increasing the amount of luminescent material in the optical path will shift the color point of the output light toward the saturated color point of the luminous medium. In some cases, the desired saturated color point of the acceptor luminophore medium can be achieved by blending two or more luminescent materials in a certain ratio. The appropriate ratio to achieve the desired saturated color point can be determined via methods known in the art. Generally speaking, any blend of luminescent materials can be processed as if they are a single luminescent material, so the ratio of luminescent materials in the blend can be adjusted to continue to meet the target CIE value of LED strings with different peak emission wavelengths. In response to the selected LED used in the LED string (101A/101B/101C/101D), which can have different peak emission wavelengths in the range from about 360nm to about 535nm, the luminescent material can be adjusted for the desired excitation. Suitable methods for adjusting the excitation and emission of the luminescent material are known in the art, and may include, for example, changing the concentration of the dopant in the phosphor.

[0038] In some implementations of the present disclosure, the luminescent medium may be provided with a combination of two types of luminescent materials. The first type of luminescent material emits light at peak emission between about 515 nm and about 590 nm in response to the relevant LED string emission. The second type of luminescent material emits at peak emission between about 590 nm and about 700 nm in response to the relevant LED string. In some cases, the luminophoric medium disclosed herein may be formed from a combination of at least one luminescent material of the first and second types described in this paragraph.

Embodiment 5

[0084] A semiconductor light emitting device with four LED strings is simulated. The first LED string is driven by a blue LED having a peak emission wavelength of about 450 nm to about 455 nm, uses an acceptor luminophor medium, and produces a combined emission of the blue color point and the 1931 CIE chromaticity diagram color point (0.2524, 0.223). The second LED string is driven by a blue LED having a peak emission wavelength of about 450 nm to about 455 nm, uses an acceptor luminophore medium, and produces a combined emission of a red color point and a 1931 CIE chromaticity diagram color point (0.5941, 0.3215). The third LED string is driven by a blue LED with a peak emission wavelength of about 450nm to about 455nm, uses the acceptor luminophore medium, and produces a combined emission of yellow/green color points and 1931 CIE chromaticity diagram color points (0.4338, 0.5195) . The fourth LED string is driven by a cyan LED having a peak emission wavelength of about 505 nm, uses an acceptor luminophore medium, and produces a combined emission of the cyan color point and the 1931 CIE chromaticity diagram color point (0.3361, 0.5257). The following Table 15 shows the spectral power distribution of the blue, red, yellow-green, and cyan color points produced by the device of this embodiment, showing that the spectral power is in the wavelength range from 380nm to 780nm in nanometers, for each Choose any reference wavelength range for the color range and normalize to a value of 100.0:
