More Information
Summary:A light emitting diode module comprising: at least one light emitting diode structure, an integrated reflector arrangement that comprises a reflector surface for reflecting light from a light emitting area of the light emitting diode structure. The integrated reflector arrangement further comprises a back reflection surface for diffusely reflecting light emitted via a side surface of the light emitting diode structure back to the light emitting diode structure. The back reflection surface is directly attached to at least a part of the side surface such that during operation of the light emitting diode module an emission of stray light by means of the side surface is reduced. The invention finally describes a flash module, an automotive front lighting or a projection light emitting diode system comprising at least one light emitting diode module.
