More Information
Summary:A LED light source module comprises a substrate whereon a circuit is present; a number of blue light emitting diodes set on the substrate and electrically connected to the circuit; a diffusion conversion layer at a predetermined distance from the blue light emitting diodes for the diffusion of the light emitted from the blue light emitting diodes and conversion of blue light into white light. The main purpose of the present invention is to provide a single-color light source, then by diffusion first and then light color conversion, or by simultaneous diffusion and light color conversion, to reduce the non-uniformity of brightness and chromaticity.
