Abstract
The invention relates to a lamp with a first light source generating white light, comprising at least one fluorescent lamp (2) or an incandescent lamp, as well as a second light source comprising at least one set of light-emitting diodes (4, 5; 300), and comprising a reflector (1) for the light emitted by the light sources, wherein a cooling device (6, 7) for the at least one set of light-emitting diodes (4, 5) is attached to the reflector (1) and is thermally linked to the at least one set of light-emitting diodes (4, 5), and wherein the lamp comprises a translucent and light-dispersing medium (3) in the optical path of the light emitted by the lamp.
Claims29
A luminaire having a first light source, which generates white light and comprises at least one fluorescent lamp (2;
- 2′;
- 200) or one incandescent lamp, and having a second light source, which comprises at least one light-emitting diode arrangement (4, 5;
- 300), and having a reflector (1;
- 1′;
- 100) for the light emitted by the light sources, a cooling device (6, 7;
- 6′;
- 400) for the at least one light-emitting diode arrangement (4, 5;
- 300) being provided that is thermally coupled to the at least one light-emitting diode arrangement (4, 5;
- 300) and is arranged on the reflector (1;
- 1′;
- 100), and the luminaire comprising a transparent, light-scattering means (3;
- 500) that is arranged in the beam path of the light emitted by the luminaire.
