Each LED group can produce light of a different color, allowing the color of the emitter to be tuned by adjusting the relative amount of operating current supplied to each LED group. This is also referred to as independent addressability. 3A-3D. In some embodiments, high CRI can be achieved in part by using a broad-spectrum phosphor, such as GAL (aluminate) phosphor compounds available from Intematix Corporation of Fremont, Calif.

FIG. In some embodiments, one or more secondary lenses (not shown), such as a total internal reflection lens, can be used to further shape the light output from emitter 102. A color-tunable LED emitter with high CRI can be made by mounting multiple LED chips onto a ceramic substrate that has been patterned with metal contacts and paths so as to connect the LED chips into multiple independently addressable LED groups. In a manufacturing environment where the color of light produced by a given LED group is reliably consistent from one device to the next, the same lookup table can be applied to all devices manufactured in that environment. FIG. 8B can appear to the human eye as a warm white light with color temperature around 2700 K. A spectrum as shown in FIG. . Our Professional LED strips. High-CRI. 3A-3C. A particular control and driver circuit is not required, and emitters as described herein can be driven by any number of different circuits. 1B described above, except that only the recess region and the LED die locations are shown. As shown, control and driver circuit 200 can receive an input control signals (e.g., indicating a desired color temperature and/or brightness). h�b```������@��(�����`ȓ �&�����IJA��i�q�oP����JF���j(0is]wک ��'�)�!�c��[�Ƿ0t2H. Nitecore TIP CRI. That’s what I was told. 6A corresponds to a CCT of about 3000 K, FIG. & Terms of Use. FIG. Where the color of light is more variable, an automated process and system can be used to determine a lookup table for each emitter, e.g., as part of an emitter manufacturing process. 17B shows a table of the CRI measurements of FIG. 4C a twelve-die configuration, and FIG. 8B can be produced by a second (warm white) LED group in which each LED consists of a “WW 2700K” chip made from a 455-nm blue LED chip coated with a mixture of GAL 535 phosphor and red nitride phosphor that produces a broad spectrum (FWHM about 130 nm) with a peak near 620 nm. As described above, the electrical connections through the ceramic substrate can be arranged such that each LED group is independently addressable. Here's another chart, comparing the led with the 5000K 83CRI Nichia 219C, and the highest bin 70 CRI XP-G3: So although the voltage of this particular led is slightly higher (0.15V at 4A), the output even matches the lower CRI Nichia 219C, which is considered a great performer. Order reliable and durable high power LED emitters available at Future Electronics. 11A corresponds to a CCT of about 2700 K, FIG. 8C can be produced by a third (red) LED group in which each LED consists of a 405-nm (near-UV) LED chip coated with a VR phosphor (a red nitride phosphor that can be efficiently excited by ultraviolet (UV) wavelengths) that produces a broad spectrum dominated by red wavelengths (roughly 630-700 nm). 2340 0 obj <>/Filter/FlateDecode/ID[<0B7C6C96D77BFA4C9C0ECBAB42B96B61>]/Index[2332 16]/Info 2331 0 R/Length 60/Prev 1548898/Root 2333 0 R/Size 2348/Type/XRef/W[1 2 1]>>stream It features a high-CRI Nichia 219B LED module that puts out a stunning 220 lumens.
