ABSTRACT:
The present invention provides a patterned wavelength converting structure comprising a frame, a light source, a substrate, a film, a wavelength converting layer and a pattern disposed on the film. The pattern and the wavelength converting layer can be one piece. The configuration, for example, the distribution of diffusion particles, the location, the shape or the thickness, of the pattern is configured to reduce the mura or affect the desired uniformity of a lighting area.
