Abstract
An arrangement for outputting light is provided, having a plurality of punctiform light sources and a light deflection element with a boundary face and/or a boundary face section, which boundary face or boundary face section is arranged in the beam path of the light of both a first light source and of a second light source. In this context, the boundary face or the boundary face section forms a light input face for the light of the first light source into the light deflection element and at the same time forms a reflective face for the light of the second light source.
Claims16
An arrangement for emitting light, comprising:
- a plurality of spaced apart essentially point light sources, and
- a light directing element having a bounding surface which is arranged in the beam path of the light of both a first light source and an adjacent second light source, wherein
- the bounding surface forms a light entry surface for the light of the first light source into the light directing element, and the bounding surface simultaneously forms an internal reflection surface for the light of the second light source.
A light directing element for influencing the light of at least two essentially point light sources arranged next to one another, having a bounding surface which is arranged in the beam path of the light of both the first light source and the second light source, wherein the bounding surface forms a light entry surface for the light of the first light source into the light directing element and the bounding surface simultaneously forms a reflection surface for the light of the second light source on its side facing away from the light entry surface.
A method for producing a light directing element for an arrangement for emitting light as claimed in one of the preceding claims comprising the following steps:
- producing, in particular injection-molding, an essentially planar light directing element,
- shaping the light directing element, in particular by cutting, so that a desired shape of the light directing element is obtained.
