ABSTRACT:
A long life light-emitting diode (LED) module is provided. The LED module includes: a light-emitting chip; 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.
