Abstract
The invention relates to a homogenizer having an input surface and an output surface which are incongruent to one another, at least one inclined surface extending between the input surface and the output surface. The inclined surface is corrugated. According to the invention, the homogenizer is designed as a hollow element which surrounds the LED chips (14) reflectively.
Claims19
A homogenizer comprising
- an input surface and
- an output surface,
- wherein the input surface and the output surface are incongruent to each other,
- wherein between the input surface (12) and the output surface (22) at least an inclined surface extends, comprising a corrugation (18),
- wherein the homogenizer (10) is formed as an internally reflecting hollow element,
- wherein LED chips (14) are accommodated in the homogenizer (10), and
- wherein the homogenizer (10) has sensor light channels (38, 40), extending between the interior space of the hollow element and a region outside the hollow element, extending in the plane of the LED chips (14).
