Abstract:
An optoelectronic lighting device includes a black housing including a cavity, wherein the cavity includes a base, a semiconductor component is arranged on the base of the cavity with an underside of a main body facing the base, and the cavity is filled with a reflective material from the base up to a predetermined height, which is smaller than a height of a top side of the main body relative to the base of the cavity such that electromagnetic radiation emerging from the main body through side faces may be reflected by the reflective material back in the direction of the side faces to couple reflected electromagnetic radiation into the main body such that at least part of the electromagnetic radiation coupled in may emerge again from the main body through the top side of the main body.
