Estimating the term…
The invention provides a lighting device (1) comprising a plurality of light sources (100) configured to generate light source light (101), a plurality of light converter elements (200), wherein each light converter element (200) is radiationally coupled with one or more light sources (100), wherein the light sources (100) are configured at a non-zero distance from the light converter elements (200), wherein the light converter elements (200) are configured to convert at least part of the light source light into light converter light (201), the lighting device (1) further comprising a plurality of compound parabolic concentrators (300) configured in an array (310), each compound parabolic concentrator (300) having a first end (301) and a second end (302), and having a shape tapering from the first end (301) to the second end (302), wherein the light converter elements (200) are configured at the second ends (302) of the compound parabolic concentrators (300), wherein the light converter elements (200) and the compound parabolic concentrators (300) are configured to provide light converter light (201) emanating from the first ends (301) of the compound parabolic concentrators (300), and wherein the light converter elements (200) are in thermal contact with a heat sink (400).
A lighting device comprising a plurality of light sources configured to generate light source light, a plurality of light converter elements, wherein each light converter element is radiationally coupled with one or more light sources, wherein the light sources are configured at a non-zero distance from the light converter elements, wherein the light converter elements are configured to convert at least part of the light source light into light converter light, the lighting device further comprising a plurality of compound parabolic concentrators configured in an array, each compound parabolic concentrator having a first endue- and a second end, and having a shape tapering from the first end to the second end, wherein the light converter elements are configured at the second ends of the compound parabolic concentrators, wherein the light converter elements and the compound parabolic concentrators are configured to provide light converter light emanating from the first ends of the compound parabolic concentrators, and wherein the light converter elements are in thermal contact with a heat sink, wherein the light sources are configured to irradiate the light converter elements via the compound parabolic concentrators.
A lighting system, selected from the group consisting of an entertainment lighting system and a digital projector, comprising one or more lighting devices.
