Abstract:
Disclosed lens designs enable uniform light distribution without hot spot, achieving wider transfer functions of light compared with traditional lenses, with a benefit of reducing the number of light sources needed and overall cost for direct-lit backlight device. A disclosed lens includes a beam shaping element on the top thereof and a backlight device incorporating the lens and the beam shaping element to eliminate a light hot spot produced by the backlight device and obtain a uniform light distribution at the illumination field. The disclosed lens is especially useful when extremely wider transfer function or extremely thin backlight is needed.

Claim (Index 1):
A light emitting device comprising:\n a light source; an optical lens coupled to and located above the light source, the optical lens including an inner curved surface and an outer curved surface that are radially symmetrical with respect to an optical axis of the optical lens and the light source; and a beam shaping element coupled to and located above the optical lens, the beam shaping element configured to scatter and redirect at least a fraction of light originating from the light source and refracted from the optical lens creating a uniform light intensity distribution pattern on a light field above the light emitting device.
