Abstract:
Optical lens and light emitting device designs achieve uniform light distribution without producing a light “hot spot”, with a benefit of reducing the number of light sources needed and overall cost for direct-lit backlight device. The optical lens includes coating portions or structures on the bottom surface thereof, and a backlight device, or other light emitting device, incorporating said lens, to produce a uniform distribution of light at a target surface. The disclosed lens and light emitting device are particularly useful when an extremely wide transfer function of backlight is needed.

Claim (Index 1):
A light emitting device comprising:\n a light source mounted to an annular mounting surface; an optical lens coupled to and located above the light source and the annular mounting surface, the optical lens including an inner curved surface and an outer curved surface, the inner curved surface and the outer curved surface being radially symmetrical with respect to an optical axis of the optical lens and the light source; and a coating portion covering at least a portion of the mounting surface, the coating portion absorbing a first fraction of light originating from the light source and refracted from the optical lens and reflecting a second fraction of the light originating from the light source and refracted from the optical lens to generate an attenuated light reflected to the optical lens and create a uniform light intensity distribution pattern on a light field above the light emitting device.
