Side emitting device with hybrid top reflector

Abstract

A side-emitting light emitting device (100) is provided, comprising at least one light emitting diode (101) arranged on a substrate (102) and facing a scattering reflector (103, 109) disposed at a distance from and extending along the extension of said substrate. The scattering reflector comprises scattering components (110) distributed in a carrier (108), and the scattering components have a refractive index being different from the refractive index of said carrier. The scattering action of the reflector gives rise to an angular redistribution in the device, which increases the chance of light exiting the device through lateral openings between the reflector and the substrate, while light is essentially prevented from being emitted through the top surface.
