WHITE LIGHT EMITTING DEVICE

摘要

A white light emitting device is enhanced in luminance by sealing a light emitting diode chip with a cast resin mixed with at least two kinds of phosphors and corpuscles of high reflectance. The white light emitting device includes a light emitting diode chip generating ultraviolet light having a wavelength range of 360-410 nm or a blue or violet light having a wavelength range of 430-480 nm and a cured compound member. The cure compound member is a liquid or solid epoxy resin mixed with at least two kinds of phosphors capable of absorbing a part of light generated by the light emitting diode chip and emitting lights of different wavelength ranges from each other, and corpuscles having high reflectance of light.
