Abstract

A lighting device with a multiple light function includes an optical component ( 1 ) which includes a transparent segment ( 1 a ) having a primary transparent part ( 2 ) and a secondary transparent part ( 3 ) which parts are connected to each other by an interconnecting channel ( 4 ). A non-transparent segment ( 1 b ) is connected to the transparent segment ( 1 a ). A primary lighting unit ( 2 a ) illuminates the primary transparent part ( 2 ) and a secondary lighting unit ( 3 a ) illuminates the secondary transparent part ( 3 ). Leading-out optics are formed by prismatic elements ( 6 ) in the interconnecting channel ( 4 ) of the transparent segment (la) of the optical component ( 1 ). Against the leading-out optics, a light absorber ( 8 ) is formed in the part of the non-transparent segment ( 1 b ) overlapping the interconnecting channel ( 4 ). The light absorber ( 8 ) being adapted to convert light energy into thermal energy.

Claims (6)

1. A lighting device with a multiple light function, comprising an optical component which comprises a transparent segment having a primary transparent part with a first rear side and having a secondary transparent part with a second rear side; an interconnecting channel connecting both the primary and the secondary transparent parts to each other, the channel having a rear side; a primary lighting unit is assigned to illuminating the first rear side of the primary transparent part and a secondary lighting unit is assigned to illuminating the second rear side of the secondary transparent part, prismatic leading-out optics is provided on the rear side of the interconnecting channel; a front side of the interconnecting channel is situated facing at least the prismatic leading-out optics and is overlapped with a non-transparent segment; a light absorber in at least part of the non-transparent segment overlapping the interconnecting channel, the light absorber being adapted to convert light energy applied on the absorber into thermal energy.

2. The lighting device according to claim 1 , wherein the light absorber comprises a dark color part of the non-transparent segment.

3. The lighting device according to claim 2 , wherein the non-transparent segment comprises a dark color material which is adapted to convert light energy on the absorber into thermal energy.

4. The lighting device according to claim 1 , wherein the light absorber on a rear/inner side of the non-transparent segment.

5. The lighting device according to claim 1 , wherein the optical component comprises by a one-piece cast comprised of two materially different segments manufactured by a multiple injection molding method.

6. The lighting device according to claim 1 , wherein the prismatic leading-out optics comprises prismatic elements on the interconnecting channel.
