Title:
OPTICAL BEAM SHAPING AND POLARIZATION SELECTION ON LED WITH WAVELENGTH CONVERSION
Document Type and Number:
WIPO Patent Application WO/2012/006123
Kind Code:
A3
Abstract:
Techniques, devices and materials for light source devices that convert excitation light into different light via wavelength conversion materials. One example of a light source includes an excitation light source; a wavelength conversion material that absorbs light from the excitation light source and emits a longer wavelength light; and a layer of a transparent material that has plural optical structures in contact to or in close proximity to the wavelength conversion material to receive the emitted light from the wavelength conversion material and to modify the received light to produce output light with a desired spatial pattern associated with the plural optical structures.
