Claims18
A light unit comprising:
- a light emitting chip emitting light;
- a light conversion layer disposed on the light emitting chip, and the light conversion layer including a resin layer and semiconductor particles distributed on the resin layer and converting a wavelength of light in accordance with their size, a diameter of the semiconductor particles being in the range of 1˜10 nm;
- and
- a buffer layer interposed between the light emitting chip and the light conversion layer to intercept the diffusion of heat and the light.
