Research on Full spectrum based on multi-band chip combination

Multi-band blue light chip and phosphor powder were used to develop the full spectrum scheme. The color index Ra of the three-band blue light full spectrum scheme reached 98.7, R1~R15>96, the light efficiency reached 132lm/W, and the E value decreased to 8.64%. High light efficiency and spectral continuity are considered effectively. A more wide-full spectrum solution whose cover band up to 1000nm was further explored to provide support for the future applications of human-centric lighting and beyond lighting.
