Abstract
An illumination device, comprising a basic body (1) having a cutout (5), a reflector (51), which is formed at least by parts of the cutout (5), and at least one optoelectronic semiconductor component (20) arranged in the cutout (5), wherein the semiconductor component (20) has an optical element (3) designed for directing at least part of the electromagnetic radiation emitted by the semiconductor component (20) during operation onto the reflector (51), wherein a radiation exit area (61) of the illumination device is at least twice as large as the sum of the radiation exit areas (44) of the semiconductor components.
Claims9
An illumination device comprising:
- a basic body having a cutout;
- a reflector, which is formed at least by parts of the cutout;
- at least one optoelectronic semiconductor component arranged in the cutout, wherein the semiconductor component has an optical element configured for directing at least part of the electromagnetic radiation emitted by the semiconductor component during operation onto the reflector,
- wherein a radiation exit area of the illumination device is at least twice as large as the sum of the radiation exit areas of the semiconductor components;
- wherein the semiconductor component is a luminescence diode comprising one or a plurality of luminescence diode chips for generating electromagnetic radiation light;
- wherein the optical element is applied to a radiation exit area of the luminescence diode;
- wherein the optical element is configured for deflecting at least part of the electromagnetic radiation emitted during the operation of the semiconductor component at an angle of at least 110° with respect to the optical axis of the semiconductor component;
- and
- wherein the deflection of the electromagnetic radiation is effected at least partly by total reflection.
