Patent ID: 7902563

Claim:
A LED (Light-emitting Diode) module comprising: a package housing; a light-emitting chip disposed inside the package housing; a phosphor layer formed of phosphor materials that transform light emitted from the light-emitting chip into light having a longer wavelength than the light emitted from the light-emitting chip; a capping layer that is formed on the light-emitting chip and protects the light-emitting chip; and a heat spreading plate that is disposed between the capping layer and the phosphor layer that dissipates heat generated in the light-emitting chip and the phosphor layer, wherein the phosphor layer and the capping layer are separated from each other by the heat spreading plate, the heat spreading plate is in direct contact with the upper surface of the capping layer and the lower surface of the phosphor layer, the heat spreading plate has a side surface in contact with the package housing and none of the side surfaces of the heat spreading plate are exposed outside of the LED module.
