Abstract
The present invention relates to a lighting module and manufacturing Method for the Same, and more particularly, to a lighting module with a flat wavelength converting structure for reducing mura. The lighting module provided by the present invention includes a frame, one or more light sources disposed on the frame, and a flat wavelength converting structure shared by the light sources for emitting light with aimed wavelength; the present invention provides a lighting module emitting light with mura that insensible to eye or with lower mura at elevated diffusion angle compared to that provided by the traditional one; therefore, the present invention also provides a lighting module occupying smaller volume; or a lighting module with fewer light sources and sharing the similar thickness of the traditional one, which emits light with similar or lower mura compared to the traditional one.
