Abstract
The invention relates to a light emitter unit having at least one VCSEL chip, which light emitter unit comprises: a light exit surface, via which light produced by the VCSEL chip and radiated perpendicularly to the chip plane is emitted into the surroundings; and contacts for supplying the electrical energy required for the production of the light by the VCSEL chip. The described technical solution is characterized in that at least one lateral surface of the VCSEL chip arranged perpendicularly to the chip plane is touched and covered, at least in parts, by a cover element.
Claims15
A light emitter unit having at least one VCSEL chip, which has a light emission surface via which light generated by the VCSEL chip and emitted perpendicular to the chip plane is emitted into an environment, and which has contacts for supplying the electrical energy required for the generation of the light by the VCSEL chip,
- characterized in that the light emitter unit does not comprise a fixed substrate as well as a rigid housing,
- in that contacts for supplying the electrical energy required for the generation of the light by the VCSEL chip are located on the underside of the light emitter unit;
- and
- in that at least one side surface of the VCSEL chip, which side surface is arranged perpendicular to the chip plane, is touched and covered, at least in sections, by a cover element, the cover element terminating essentially planarly with the light emission surface.
