| abstract | The utility model provides a LED module, the inside LED unit that is equipped with of LED module, the LED unit includes a plurality of blue light LED chips, the blue light LED chip includes a fixed wavelength range 457.5-480nm blue light LED chip and at least one different wavelength blue light LED chip, the LED module still is equipped with the optical layer, the top of LED unit is located to the optical layer, the optical layer includes the multiunit phosphor powder, the peak wavelength of multiunit phosphor powder is different, fixed wavelength blue light LED chip and at least one different wavelength blue light LED chip combination excitation optical layer realize white light output. According to the LED module, the color rendering property is improved while the high-energy blue light occupation ratio in the high-color-temperature white light is low by combining the LED units with different wavelengths with the optical layer consisting of the fluorescent powder with different peak wavelengths, and the problems that in the prior art, the white LED module only directly excites one fluorescent powder combination mode through one wavelength chip, so that the high-energy blue light occupation ratio in the white light is high and the color rendering property is poor are solved. |
