Abstract: A light-emitting device is disclosed, including: a substrate; a light-emitting diode (LED) formed on a first surface of the substrate, the LED being arranged to emit primary light; a fence disposed on a second surface of the substrate, the fence including a plurality of walls arranged to define a cell; a light-converting structure disposed in the cell, the light-converting structure being arranged to convert at least a portion of the primary light to secondary light having a wavelength that is different from the wavelength of the primary light; and a reflective element formed on one or more outer surfaces of the walls of the fence, such that the reflective element and the light-converting structure are disposed on opposite sides of the walls of the fence.

Abstract: A semiconductor light emitting device (100;200;300;400,400B,400C;500;600;700) may have a reflective side coating (120;220;320;420;520;620;720) disposed on a sidewall (118;215;315;415,435;515) of a semiconductor light emitting device structure. Such a device may be fabricated by dicing a semiconductor structure to separate a semiconductor light emitting device structure and then forming a reflective side coating (120;220;320;420;520;620;720) on a sidewall (118;215;315;415,435;515) of the separated semiconductor light emitting device structure.

Abstract: 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.
