Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention generally relates to systems and methods for providing mixed light. More specifically, the various inventive methods and apparatus disclosed herein relate to controlling a plurality of primary light sources to provide a desired color point of light. [Prior Art] Digital illumination technology (i.e., illumination based on semiconductor light sources such as light emitting diodes (LEDs)) provides an operative alternative to conventional fluorescent lamps, HIDs, and incandescent lamps. The functional advantages and benefits of LEDs include high energy conversion and optical efficiency, durability, low operating costs and many others. In many applications, the latest advances in LED technology have provided efficient and robust full-spectrum illumination sources that enable multiple illumination effects. Some of the instrumental features that embody these sources are a lighting module that contains different colors (eg, One or more LEDs of red, green, and blue) and a processor for independently controlling the output of the LEDs to produce a variety of color and color-changing lighting effects, such as U.S. Patent No. 6, 〇 16, It is discussed in detail in 〇38 and 6,211,626. The mixed light of a particular color point can be produced by combining the primary color sources into a resulting color. For example, when combining three primary colors (e.g., red, green, and blue), each of the colors in the three primary colors can be achieved. When the two primary colors of light are combined, only the color points on one line between the two primary colors can be achieved. However, a problem arises when combining light from more than three primary colors, since more than one combination of such primary colors can often be used to achieve a desired color point in the color gamut, and because when compared to each other 160698.doc At 201236510, these combinations can have significant differences in luminous flux output. A known solution to this problem selects one of a number of primary color combinations that provide light of a desired color point and causes the light sources to cycle through the selected time of action in an attempt to achieve the color point. However, the known solutions do not smoothly control the transition between color points as the output of the light sources changes over time, or when a different color point is selected. The lack of such a smooth transition between color points degrades the quality of the light and can be noticed by a viewer. Therefore, there is a need in the art to provide an illumination system and method for providing a mixture of desired color points from a group of primary color sources that have a smooth transition when the desired color point changes across the color gamut. control. SUMMARY OF THE INVENTION The present invention is directed to an inventive method and apparatus for providing illumination from an illumination source. For example, a reflector includes an array of solid state light sources. Each source emits light of a primary color, and different combinations of the sources emit light of the same color point on the color gamut. A control system sorts a plurality of selections of light that emit a particular color point, and &&;; many combinations select the best combination of light sources that emit light of that color point having the best characteristics. / - Generally speaking, in one aspect, an illumination system includes a reflector and is operable to emit at least four solid state light sources. The illumination system also includes a controller to identify a plurality of combinations of the solid state light sources, wherein each of the combinations is operable to emit light that matches a target color point. The controller sorts the combinations based on the respective luminous flux values of the combinations, and selects one of the combinations based on the ranking. The controller determines the selection: 160698.doc -4 - 201236510 A combined time cycle of a control signal for each of the combined light sources to control the light emitted by the reflector from the selected combination. In one aspect, a method provides illumination from a source of illumination utilizing a plurality of solid state light sources. The method identifies a plurality of combinations of the plurality of solid state light sources wherein each of the plurality of combinations is operable to emit light that matches a target color point. The method also ranks the combinations based on a respective luminous flux value of each of the plurality of combinations, and selects one of the plurality of combinations based on the ranking as a selected combination. The method determines an active time cycle of a control signal for each of the selected combinations of light sources and adjusts the active time cycle of each of the light sources to control the light emitted by the selected combination. In an aspect, a computer readable medium encoding a program is provided for 'executing' for execution on a processor, and when executing the program on the processor, performing one from a plurality of solid state light sources The light source provides ..., the clear - method. The method identifies a plurality of combinations of the solid state light sources, wherein each of the combinations is operable to emit light that matches a target color point: the method ranks based on a respective luminous flux value of each of the combinations " Hai et al. 'and select a plurality of such combinations based on the ranking. The method individually determines an active time cycle for each of the plurality of selected combinations of the plurality of combinations, and determines a total active time cycle for each of the light sources based on the individual active time cycles. The method also controls the light emitted by the selected combination based on the total time-cycle of the cycles. j. In the embodiment, a selected combination of the plurality of combinations emits a light-to-light flux value that is greater than a luminous flux value of each of the plurality of (four) combinations of each of the other 60720.doc 201236510. In some embodiments, an active time cycle budget is determined based on a duty cycle of each of the light sources of the selected combination, and one of the plurality of combinations is selected based on the ranking. A time period of each source of the combination of the second selections may also be determined based on the duty cycle budget. In an embodiment, a total active time cycle of the light sources is determined based on the active time cycle of each light source for each light source of the selected combination and the second time combination. For at least one of the light sources, it may also be determined that the "cumulative action time" provided by the plurality of combinations is greater than one. In one embodiment, a light source is defined based on the at least four light sources, and a time-duration cycle of the composite light source-light flux value m composite light source is identified based on the light flux of the two light sources, and (4) The composite light source is utilized by combining a plurality of combinations of the light sources. In one embodiment, the illumination system includes a photodetector. The reflector can be - tubular reflective n' and can comprise a supply of wire from the source to the photodetector. The time-lapse % can be adjusted based on the information received from the photo-sensitivity detector. In some embodiments, the

''For purposes of the present invention', as used herein, the term "LED" shall be taken to include any electroluminescent diode or other type of carrier-based injection/connection that may respond to an electrical signal. Surface system. Therefore, the LEDs include, but are not limited to, a variety of semiconductor-based, photoluminescent, organic light-emitting diodes, electroluminescent strips, and the like that respond to current-emitting light. 'The term LED refers to one or more of a variety of parts that can be configured to be in the infrared, east light, a ultraviolet spectrum, and the visible spectrum (generally containing a radiation wavelength from about 4 nanometers to about 700 nanometers). Radiation generates all types of light-emitting diodes (including semiconductors and organic light-emitting diodes). Some examples of LEDs include, but are not limited to, various types of infrared LEDs, ultraviolet LEDs, red LEDs, blue LEDs, green LEDs, yellow LEDs. , amber led, orange LED, and white LED (discussed further below). It should also be understood that LEDs can be configured and/or controlled to produce for a given spectrum (eg, 'narrower bandwidth, wider bandwidth') Radiation with multiple bandwidths (eg 'half height full width, or FWHM'), and multiple major wavelengths in a given general color classification, such as 'an LED configured to produce substantially white light (eg, white) The implementation of the LED) may comprise a plurality of grains which respectively emit electroluminescence of different spectra which are combined to form substantially white light. In another implementation, a white LED Associated with a phosphor material that converts electroluminescence having a first spectrum into a different second spectrum. In one example of this implementation, there is a phase 160698.doc 201236510 pumping" The longer wavelength of the broad spectrum of the phosphor versus the shorter wavelength and narrower bandwidth spectrum of the electroluminescent Γ material, which in turn has a somewhat longer radiation to some extent. It should also be understood that the term LED does not limit the physical and/or electrical package type of an LED. For example, as discussed above, an LED can refer to a single light emitting device having a plurality of dies configured to emit different spectra of the respective spectra (eg, which may or may not be individually controllable), _ [ED can be associated with a phosphor that is considered an integral part of one of the LEDs (eg, some types of white LEDs). In general terms, the term brush may refer to packaged led, unpackaged LEDs, surface mount LEDs, on-board wafer LEDs, package mounted LEDs 'radial package lEDs, power package LEDs, include some types of covers and/or optics The LED of the component (for example, a diffuser), and so on. The term "light source" is understood to mean any one or more of a plurality of radiation sources 'including but not limited to LED-based sources (including one or more LEDs as defined above), incandescent sources (eg 'incandescent lights, teeth Prime lamp), fluorescent light source, phosphorescent light source, high-intensity discharge power source (such as Shishikou, sodium vapor lamp, mercury vapor lamp and metal toothed lamp), laser, other types of electroluminescence source, thermoelectric light source (for example, flame ) 'candle source (eg, lamp cover, carbon source), photoluminescence source (eg, gas discharge source), cathode-illuminated U-light source using electron saturation, crystal illumination source, motion illumination source, thermal illumination source , a rubbing light source, an sono light source, (four) a light source, and a light emitting polymer. A given source of light can be configured to produce electromagnetic radiation in one or both of the visible spectra outside the visible spectrum. Therefore, the term "light" and "radiation" are used interchangeably herein. Additionally, a light source can include one or more filters (e.g., color filters), diffusers, or other optical components as a unitary component. It should also be understood that the light source can be configured for a variety of applications including, but not limited to, indication, display, and/or illumination. An "illumination source" is a source of light that is specifically configured to generate radiation having a sufficient intensity to efficiently illuminate an indoor or outdoor space. In this context, "sufficient strength" refers to space or Sufficient radiant power in the visible spectrum produced in the environment (usually using the unit "lumens" to represent the total light output from a source in all directions versus radiant power or "light flux") to provide ambient illumination (ie ' Light that can be indirectly perceived, and can be reflected from one or more intervening surfaces, for example, before or in whole or in part. The term "spectrum" is understood to mean any one or more frequencies of radiation produced by one or more sources ( Or wavelength. Accordingly, the term "spectrum" refers to a frequency (or wavelength) that is not only in the visible range, but also in the infrared region, the ultraviolet region, and other regions of the entire electromagnetic spectrum. A given spectrum may have a relatively narrow bandwidth (eg, a FWHM having substantially less frequency or wavelength components) or a relatively wider Wide (frequency or wavelength component with multiple relative intensities) It should also be appreciated that a given spectrum can be the result of mixing one of two or more other spectra (eg, mixed radiation emitted from multiple sources, respectively). For the purposes of the present invention, the term "color" can be used interchangeably with the term "spectrum." However, the term "color" is used primarily to refer to the nature of the radiation that can be perceived by a viewer (although this usage is not intended Limit the scope of this term.) The term 'different colors' implies different spectra with different wavelengths of 160698.doc 201236510 components and/or bandwidth. It should also be understood that the term "color" can be used with both white and non-white light. The term "color temperature" is used herein generally in conjunction with white light, although this usage is not intended to limit the scope of the term. Color temperature essentially refers to a particular color content or shade of white light (eg, , reddish, bluish), according to convention, the Kerr temperature of a blackbody radiator that radiates substantially the same spectrum as a given radiation sample (κ) characterizing the color temperature of the radiation sample in question, the color temperature of the black body radiator generally falls from about 700 degrees Κ (usually regarded as the first one visible to the human eye) to more than 1 κ κ Within a range; white light is generally perceived as a color temperature greater than ^(9) to 汕(eight) degrees κ. Lower color temperature generally indicates white light with a more pronounced red component or a "warm sensation", while the southern color temperature generally indicates a more pronounced blue component or a "cold feeling" of white light. By way of example, the fire has a color temperature of about ^(9) red, a conventional incandescent bulb has a color temperature of about 2,000 degrees. a color temperature of one degree, and the sky of the midday cloudy has a color image of about 10'GGG degrees κ-color temperature. The color image having a color temperature of about 3, _ degrees K has a relatively reddish hue, and has a A color image of the same color temperature of about 1 inch, _ degree 具有 has a relatively slight blue hue when viewed under white light. The technique m "lighting device" used in this document is implemented or configured with one or more lighting sheets it, assembly or package of a specific appearance size. The term "lighting unit" as used herein includes a device that has one or more light sources of the same or different types.

及BGA。其他原色光源11〇組合及排序係可能的，例如， 為匹配該色域中的不同目標色彩點。控制器n 5選擇相對 於其他組合對該總通量貢獻最多的組合（例如，BRW)，且 識別該選擇之組合的每一光源110(B、R及W)的作用時間 循環。在此實例中，此等作用時間循環從1(總作用時間循 環預算）減去，以獲得對於光源11 〇可用的剩餘作用時間循 160698.doc • 18- 201236510

在-實施例中，色彩點或光源叫之通量隨時間、使用 及/或溫度而改變。例如’ LED驅動電流或作用時間循環可 影響光源溫度’此繼而影響該光源的輸出波長。在一實施 例中，溫度感測器125感測該溫度，且光敏债測器12〇感測 至少一光源110的通量，且將此資訊提供至控制器115。基 於所感測的溫度回饋，控制115預測未來的光源溫度，且 調整光源110的色彩點，以考量所估計的未來溫度波動。 基於所感測的通量資訊，及光源110的校準（例如，工廠決 定）之通量值，控制器115可決定光源11〇相對於彼此的作 用時間循環比率在變化，或將變化，且可調整光源11〇的 作用時間循環，將其等之比率保持恆定，以維持該目標色 彩點之最大通量。根據一實施例，溫度感測器i 25監測安 裝該光源之一基板的一溫度。 光源110可包含至少一複合光源。例如，控制器1丨5可基

[Embodiment] In the figure, 'the same reference character generally refers to the same part throughout different views. Again, the drawings do not have to be proportional. (d) Instead, the principle of the invention is generally emphasized. It is still a problem to find the best combination of such primary colors in a color point in the color gamut due to more than one combined primary color. It has been recognized and appreciated that it would be beneficial for a plurality of sources to find a light combination that emits light of a desired color point having the best characteristics (such as the amount of 160698.doc -14·201236510). Various embodiments and implementations are directed to illumination systems and methods for identifying a plurality of primary color light source combinations that emit light of a desired color point and controlling the light sources to emit mixed light having the highest achievable flux. Referring to FIG. 1, in an embodiment, the illumination system 100 includes at least one illumination unit 105. The illumination unit 105 includes a plurality of solid state light sources 11A, such as one or more LEDs. For example, each light source 11A can include a primary color ( One or more LEDs of light such as red, green, blue 'cyan, berth, variegated, deep red, or white, and others. In one embodiment, the illumination unit 105 includes at least four light sources 11A, each configured to emit light of a different primary color. The illumination unit 105 can also include at least one controller. , a photodetector 120 and at least one temperature sensor 125. The controller 115 generally determines the duty cycle of the control signal of the light source m based on information from the photodetector 12 or the temperature sensor, which can be used to determine the luminous flux output of the light source and The wavelength as well as the predetermined information or desired output, such as a target color point. The controller 115 can be included in or separated from the illumination unit 105. In the embodiment, the controller i J 5 causes the light source i i to perform the intervening loop according to its calculation. The illumination unit 105 mixes the light emitted from the light source 110 to provide a mixed light that can be output from the illumination unit 105 to optimally output the target; the color point illuminates the object. For example, the controller (1) can determine the individual action time of the source 110 such that the mixed output light of the target color point has a maximum achievable flux. 160698.doc -15· 201236510 FIG. 2 depicts an example of a lighting system 100. Referring to Figure 2, in one embodiment, a plurality of light sources 11 are configured to emit light toward at least one reflector 205. Reflector 205 includes a reflective inner surface, an inlet aperture, and an outlet aperture. In one embodiment, light source 110 forms an array that emits light into the inlet aperture and exits the exit aperture. Light from a plurality of light sources 110 is mixed in reflector 205 and exits through the exit aperture. The light can be collimated into a white light beam having a hard edge that is operable, for example, as a projection concentrating light in a movie theater. In an embodiment, the exit aperture is larger than the inlet aperture. Reflector 205 can be a tubular reflector, or a variety of other shapes' including cylinders and polygons. In one embodiment, the reflector 2〇5 includes a plurality of light guides 210. The light from the at least one light source 11〇 follows at least one light guide 210 to the photodetector 120, and the photodetector 120 can sense the respective light sources 110. Luminous Flux Figure 3 depicts a color point from a color gamut that can be obtained from a combination of multiple primary colors. In the example of Figure 3, there are five sources 丨丨〇 on the color gamut, namely 'red (R) 'green (G), blue (b), amber (A) and white (W). Other light sources 110 are possible, such as cyan or magenta. The color points 0 and ^ coordinates falling within the triangle created by the combination of any three light sources 110 can be obtained by mixing the light of the respective light sources 11 。. For example, a target color point having (X, y) coordinates of (〇 35, 0.25) is depicted in FIG. A combination of light sources (the triangles of which are equal to the target color point) provide mixed light at this target color point. In this example, each of the BRW, BGR, bga, and baw combinations includes three light sources 11 that provide mixed light at the target color point (〇.35, 0.25). In addition, the primary color combinations BGW, GAW, ARW, GAR, 160698 .doc -16 * 201236510 BAR and GRW do not overlap the target color point and do not provide mixed light that matches the target color point of Figure 3, for example, see Table i. Is it in the BGW GAW ARW BRW BGR GAR BGA BAR GRW BAW gamut? No No No Yes, whether or not it is Table 1 According to some embodiments, the controller 115 evaluates such combinations and determines one of the individual light sources 11 〇 (eg, R, G, B, A, and W) PWM control signals The action time loop provides the mixed light of the target color point with the highest achievable luminous flux. For example, controller 15 identifies the target color point, which is provided as an input to controller 丨丨5 and identifies the color point of source 11 〇. Controller 115 also identifies or determines the maximum flux of source 11〇. The controller (1) identifies from the input information a combination of the light sources (10) covering the target color point (eg, 'a possible triangle on the (x, y) axis of the color gamut, as shown in the table.) Continue this example 'Controller 115 calculation Forming a time period of action of the individual light sources 110 providing the combinations of the target colors. For example, where each of the BRW, job, BGA, and BAW combinations covers the target color point, the controller 115 determines the pair of _ 卜梦 &, 蓝色 for each of the # combination of the blue, red, white, green and amber light trace time loop. ', G of each - the role of the control signal in an embodiment, when off Bamboo Technique - First] The controller 115 adds the action time S, 〇^^. 每 of each light source of each combination to match the target color point. According to this example, by the defending The selected time is the time of the primary color light source of the rites. The respective ones # select the light source Μ 1 and the values are added together to determine a cumulative action time of each source. The primary color source selected appears in the I60698.doc -17- 2012365 10 selected combinations). Thoughts. From the combination of the four choices ^ before the example, the blue light source contains color, white, station color and green ^ time loop, and the red color, the source Each of them includes a time-cycle of action within the four choices, and S. When a combination is formed, the cumulative action time of the light source 110 is 衮When less than 1, the controller acts on the time loop operation, and each light source 110 contributes to the mixed output light that matches the target color point according to the accumulation, and the mother-light source " 0. In the embodiment, , the cumulative action time of & to j - is greater than b. For example, if the action time cycle of the blue light source no is (4) in the BRW combination, and 0.68 in the BGR combination, the cumulative action time Circulation system 128. According to an embodiment, the blue light source 11 无法 cannot fully contribute to both the BRW and BGR combinations in this example (ie, an action time loop ratio greater than earned is not b). And the controller 115 performs further operations to each The cumulative action time cycle of source H0 is reduced to a value no greater than 1. According to some embodiments, controller 115 ranks the combinations of the total luminous flux according to the combinations. For example, 'the combined light source 1 You can sort 'from highest to lowest flux: BRW, BAW, BGH, and BGA in the following order. Other primary color sources 11〇 combination and ordering are possible, for example, to match different target color points in the color gamut. Control The n5 selects the combination (e.g., BRW) that contributes the most to the total flux relative to the other combinations, and identifies the active time cycle of each of the light sources 110 (B, R, and W) of the selected combination. In this example, these action time cycles are subtracted from 1 (total action time cycle budget) to obtain the remaining action time available for source 11 循. 160698.doc • 18- 201236510 Clothing budget, for example, if blue light source lio In the combined BRW, there is an action time 〇 of 〇59; for the I ring, for the remaining combination, the remaining action time cycle budget of the blue light source 11G is 〇·41. The controller 115 then selects the magical remainder combination with the highest throughput and compares the active time cycle and the remaining active time cycle budget for this second combination. The action time cycle of the combination of the second selection is subtracted from the remaining active time cycle budget and can be scaled to fit within the budget. This procedure can be repeated until it has included every combination that covers the target color point. For example, in one embodiment, the time of action of the one or more light sources of the third selected combination exceeds the remaining active time cycle budget. In this example, the controller 15 scales down the active time cycle of the light source 110 forming the selected combination to maintain the active time cycle within the remaining budget. When scaled in this manner, the combination of the choices reduces the contribution of the mixed light output of illumination unit 1〇5 (or reflector 2〇5). In one embodiment, the controller 115 determines the active time cycle of the combination of the light sources 110 that match the target color point, and adds them for each light source 11 to determine the total duration of each light source 110. Loop to achieve the light of the target color point with the highest achievable flux. For example, referring to Table 1 'blue (Β) light source 110 is a portion of the four combinations of output light of the target color point. Here, according to an embodiment, the controller 1丨5 adds the action time cycles of the light source for each combination, and scales the equal-action time cycle scaling to maintain the total active time cycle less than Or equal to 1. The blue light source 1 in this example is cyclically operated according to the added action time, which is scaled, and the total action time cycle is I60698.doc •19· 201236510 The budget upper limit is 1 〇 controller 115 control — Each light source 110 is part of the matched combination to determine the T-cycle of the total action, and to cause the light source 110 to operate in accordance with the total active time of the separation, which leads to the achievement of the target by the parent The maximum flux of color points. In an embodiment, the color point or source of light is said to vary in flux over time, usage, and/or temperature. For example, 'LED drive current or duty cycle can affect the source temperature' which in turn affects the output wavelength of the source. In one embodiment, temperature sensor 125 senses the temperature, and photosensitive detector 12 detects the flux of at least one source 110 and provides this information to controller 115. Based on the sensed temperature feedback, control 115 predicts the future source temperature and adjusts the color point of source 110 to account for the estimated future temperature fluctuations. Based on the sensed flux information, and the flux value of the calibration (eg, factory decision) of the light source 110, the controller 115 may determine that the time cycling ratio of the source 11 〇 relative to each other is changing, or will vary, and may be adjusted The action time of the light source 11 循环 is cycled, and the ratio of the light source is kept constant to maintain the maximum flux of the target color point. According to an embodiment, the temperature sensor i 25 monitors a temperature at which the substrate of one of the light sources is mounted. Light source 110 can include at least one composite light source. For example, controller 1丨5 can generate a composite light source based on the color points and the flux values of two or more light sources. For example, when compared to the blue 'green or white source 丨丨 0, the red (R) source 110 and the amber (A) source 110 are relatively close to each other in the color gamut of FIG. The controller 115 can generate a composite light source between the red light source and the amber light source 110, e.g., by adding the fluxes and determining a color point that is closest to the two light sources 110. By combining the red and amber 160698.doc •20·201236510 color (or any other) combination of light sources 11 一 into a single composite light source, the number of light sources 110 is effectively reduced by at least one 'eg, from five to four . This approach reduces the number of possible primary color combinations that cover the target color point, and thus reduces the amount of information processed by controller 115. For example, in Table 2, the composite light source is represented by a "C". Is it in the color BGW GCW BCW BGC domain? No No Yes Yes Table 2 Referring to Tables 1 and 2, combining the red and amber lights 丨1〇 into a composite source reduces the number of matching combinations from four to two. In Table 2, the red (R) and amber (Α) light sources 11 〇 are represented by the composite light source c, and the combination of the target color points is BCW (blue, composite color, white) and BGc (blue two green, Composite color). In one embodiment, the '(4) device" 5 then sorts the matching combinations from highest to lowest flux, and determines the duration of each light source for each of the matching combinations. ^ If the sum of these action time cycles is greater than 1, then the combination of the highest order is selected, the action time cycle is identified, and subtracted from the action time cycle budget 1. The remaining action time cycle budget is applied to the next highest order of the matching combinations (by flux), if necessary, scaled to match each color in the group of a & u items The total action time cycle is maintained within the budget. For the ancient #松, 斤 has the matching of each of the combinations of the light source 11 0 add effect time 砰 cycle ' budget 1 is the maximum action time cycle. In one embodiment, the copying time 15 U5 applies the appropriate time of the composite light source to the two (or evening) light sources that produce it, for example, the red and amber colors in the example of Table 2. 160698.doc •21. 201236510 In an embodiment, the illumination system 100 includes blue, green, amber, red, and white (eg, t white) light sources 110, and saturated colors: at least 148 for blue. Lm, at least 1700 lm for green, at least 873 lm for station color, at least 7 〇 9 im for red, and at least 4700 lm for white. These numbers are for example 'and in another embodiment the luminous flux of source 110: at least 235 1 ίη for blue, at least 2608 lm for green, at least 1289 lm for amber, at least 1048 lm for red, and for White is at least 58〇8 lm. The color temperature of the light output from the illumination unit 1〇5 can be changed within a predetermined range. For example, in the embodiment the light output is between 2700 K and 6500 K. In one embodiment, the illumination system 1A includes blue, green, amber, and red light sources 110' having peak wavelengths of 448 5 nm, 515.9 nm, 599.6 nm, and 6423 nm, respectively, and a white light source has ( - (X, y) color point of 0.3895, 0.3798). In this example, the illumination system is provided with at least 148 for blue, at least i7 lm for green, at least 873 lm for amber, at least 7 〇 9 丨 (7) for red, and 4700 im flux for white to eve 胄The saturated color. & In another example having such wavelengths and color points, the flux values are at least 235 for blue and at least 2608 lm for green, at least 1289 lm for amber, and at least 1 for 48 for red. And for white, at least $ in this example, the tolerance of the target color point within the color gamut is expressed by equation (1): 160698.doc • 22- 201236510 In an embodiment, provided by illumination system 100 The standard deviation of the colors is less than 5 sdem over the full range of the color gamut, and different light sources may have different deviations from the target color point. For example, the green, green, station color, and red light sources 110 may deviate from the target color points by 〇 001, 〇〇 〇〇 4, 0.003, and 0.002, respectively. Figure 4 illustrates a flow diagram of a method 4 of providing illumination from a lighting unit. In one embodiment, the method 4 includes an action of identifying color points of the plurality of light sources (act 405). For example, at least four color points of a primary color source may be identified by their (x, y) coordinates on a color gamut or by color temperature (act 405). Method 400 also identifies a target color point (action 41 〇). For example, the identified target color point can be provided as an input in an illumination system in which the mixed light output from the system is provided in accordance with the target color point. Method 4A also includes an act of identifying a combination of sources that match the target color point (act 415). For example, 'three light sources form a triangle on a color gamut and the combination of these three light sources provides light at any color point within the triangle. When the triangle covers the target color point, the corresponding source combination can achieve light at all points within the triangle, and thus match the target color point (action 415). In an embodiment, the identified matching combinations are ordered (act 420) (act 41 5). For example, the combinations can be ordered in order of flux, with the highest combination of matching combinations ranked first, and the lowest combination of matching combinations at the end. The highest ranked combination is selected (act 425) and the action time loop for each light source forming part of the combination is determined (act 430). The remaining active time cycle budget can be determined, for example, by subtracting the active time cycle of the first selected combination of light sources from an initial active time cycle budget of 1 160698.doc • 23· 201236510 (act 435), And method 4 〇〇 can continue to select the remaining combination of the last-last sort (action 44〇). For example, method 4 继续 may continue to select after the previously selected combination. The remaining matching set 0 having the highest throughput may determine the active time cycle of each of the remaining combinations of the selection (act 445), and may The budget decision (ACT 435), the remaining (four) material (action 44), and the action time loop decision (action 445) program are repeated for each matching combination in a flux-based sorting order (act 450). In an embodiment, the $ method 400 includes an action (action 乜) that determines the total active time cycle of each light source. The exemplified by the combination of the first selection (act 430) and each of the remaining combinations The action time determined by the light source (ACT 445) is added to determine the total inter-feed cycle (ACT 455). The light sources can then be determined (ACT 455) for the inter-feed cycle operation (Action 46G). The hybrid output light having the highest achievable flux is provided at the desired target point. Figure 5 illustrates a method of providing illumination from a lighting unit. A method 500 is generally not shown for each matching combination. The action time cyclic allocation of the light source 'which occurs in one embodiment for each matching combination in the highest to lowest sort order (action, in the embodiment with the complex matching ^ combination), method 5 〇〇 contains comparison The action time cycle of each light source and the action of the time-cycle of the budget (action 5〇5). For example, the action time cycle of the first-selected match combination is from an initial budget U, which represents the maximum action time. Subtracting, the difference is the remaining action time cycle.

If the decision exceeds the budget, a scaling factor is determined (act 515), and the duration of the action of all of the light sources included in the selected combination is scaled down according to the scaling factor. , to fit within the budget. This attenuates the light from the selected, scaled combination. In this example, whether or not it is scaled according to the aforementioned action result, then the remainder of the selection The combined light source establishes an active time loop (act 525).

In an embodiment, method 600 includes the act of combining color points of a plurality of light sources (moving 6〇5) to generate a composite color point; and combine the flux of the plurality of light sources (action 6丨0) to generate a composite flux value. A composite light source is defined by the combined source color point and flux value (action 615 The time cycle, flux, and color point of the light source can be determined or adjusted with any other primary color source.
