Full spectrum LED light in COB package and its characteristics
In order to improve the color rendering index of light source
a full spectrum LED light source of COB package is designed and manufactured
by adding the peak wavelength 415 nm of violet LED chip and luminous peak wavelength 497 nm and 655 nm phosphor
the energy distribution of common LED light source in the spectral range of violet
blue-green and red light is make up. The experimental results show that the luminous efficiency is 103.34 lm/W
the color index of the full spectrum LED is as high as 99.38
and it is close to the color index of sunlight
which can meet the requirement of high quality illumination.
