Novel multi-layer remote phosphor linear optics for solid state lighting

As LEDs move into general lighting developing high efficiency, optically uniform linear light sources is critical. Presented is a new linear light emitting optic designed to work with blue LEDs (450-460nm). This white appearance remote phosphor optic combines a high efficiency phosphor down-converter layer with an integrated secondary optic into a single component. The optic is produced using co-extrusion of two different optical materials into a single component.
