ABSTRACT:
A high luminous flux warm white solid state lighting device with a high color rendering is disclosed. The device comprising two groups of semiconductor light emitting components to emit and excite four narrow-band spectrums of lights at high luminous efficacy, wherein the semiconductor light emitting components are directly mounted on a thermal effective dissipation member; a mixing cavity for blending the multi-spectrum of lights; a back-transferred light recycling member deposited on top of an LED driver and around the semiconductor light emitters; and a diffusive member to diffuse the mixture of output light from the solid state lighting device. The solid state lighting device produces a warm white light with luminous efficacy at least 80 lumens per watt and a color rendering index at least 85 for any lighting application.
