ABSTRACT:
A light emitting diode comprising an LED chip having a light emitting layer made of a nitride compound semiconductor and a light transmitting resin that includes a fluorescent material which absorbs at least a part of light emitted by the LED chip and emits light of a different wavelength, wherein the fluorescent material includes a fluorescent particles of small particle size and a fluorescent particles of large particle size, the fluorescent particles of large particle size being distributed in the vicinity of the LED chip in the light transmitting resin to form a wavelength converting layer, the fluorescent particles of small particle size being distributed on the outside of the wavelength converting layer in the light transmitting resin.
