Lighting appliance for vehicles
A lighting appliance for vehicles includes a flat light guide having a light coupling section for the coupling of light into a first or a second end of the light guide, a narrow-side front serving as a light coupling section for the coupling-out of light into the main radiation direction extending between the first end and the second end of the flat light guide, a first flat side and a second flat side arranged on the opposite side, on which the coupled-in light can be fully reflected, a rear extending between the first end and the second end of the flat light guide having a number of optic elements for the redirection of the light into the direction of the narrow-side front, wherein the flat light guide is held with fastening means in a holding section of a holding lens running at right angles to the main radiation direction.
1. A lighting appliance for vehicles comprising:
a flat light guide;
a light coupling section for the coupling of light into at least one of a first or second end of the light guide;
a narrow front serving as a light coupling section for the coupling-out of light into the main radiation direction extending between the first end and the second end of the flat light guide;
a first flat side and a second flat side arranged on the opposite side, on which the coupled-in light can be fully reflected;
a rear extending between the first end and the second end of the flat light guide having a number of optic elements for the redirection of the light into the direction of the narrow front;
wherein the flat light guide is held with fastening means in a holding section of a holding lens running at right angles to the main radiation direction.
2. The lighting appliance according to claim 1 , wherein the holding section of the holding lens has a groove in which a fastening web of the flat light guide can engage for fastening the flat light guide on the holding lens.
3. The lighting appliance according to claim 2 , wherein the flat light guide can be fastened in at least one of a form-locked, force-locked, and substance-to-substance bonded manner in the groove of the holding lens.
4. The lighting appliance according to claim 1 , wherein the holding section of the holding lens has a stopping face on which the rear of the flat light guide abuts, wherein the stopping face is at least one of opaque and with optic elements.
5. The lighting appliance according to claim 1 , wherein the holding lens has several holding sections with at least one groove each for holding a plurality of flat light guides arranged at a distance relative to one another, the lighting appliance further including a light passage section with at least one of a translucent and transparent light passage surface between the holding sections.
6. The lighting appliance according to claim 1 , wherein the holding lens is integrally molded as an injection-molded part comprising two components, wherein the holding section of the holding lens on one hand is at least one of opaque and with optic elements and the light passage section is transparent.
7. The lighting appliance according to claim 1 , wherein a flat blind abuts a flat side of the flat light guide with a front having the same contour as the front of the flat light guide, and wherein the flat blind is at least one of opaque and with an optical structure.
8. The lighting appliance according to claim 7 , wherein on a side facing the holding lens, at least one of the flat light guide and the flat blind has a transverse step being held in the groove of the holding lens, and wherein the transverse step of the flat light guide has a length corresponding at least to the sum of a thickness of the part of the flat light guide and the flat blind abutting in the main radiation direction.
9. The lighting appliance according to claim 1 , wherein the narrow front of the flat light guide has an optical structure.
10. The lighting appliance according to claim 7 , wherein at least one of the rear of the flat light guide and the flat blind can be fastened in the groove of the holding lens by means of rivets or screws or by welding.
