Coupling device for light of two light sources on common printed circuit board in light guide of light guide device, has coupling surfaces arranged such that printed circuit board is arranged with light sources at coupling surfaces

摘要

The coupling device (10) has a coupling surface (20a) for each light source, and is connected with a transition surface (30) of a light guide in a light-conducting manner. The coupling surfaces are arranged in such a way that a printed circuit board is arranged with the light sources at the coupling surfaces at an angle greater than 40 degrees relative to the transition surface. Sections for the connection are arranged to the transition surface as a light guide section (42a) in light transmitting manner based on each coupling surface.
