Problems solved by technology

[0012] Therefore, the rotationally symmetrical structure of the reflector leads to a limitation of the design freedom of the entire lighting device
Nor does it provide any possibility to implement other functions of the lighting device, such as side visibility

Embodiment Construction

[0033] figure 1 A rotationally asymmetrical motor vehicle lighting device according to the invention is shown schematically.

[0034] The motor vehicle lighting device 5 comprises in particular: a light source 1 ( figure 1 Not shown in ), the light source 1 single LED; The light-transmitting portion 2 is dimensioned in a conventional manner such that it provides a sufficient portion of the light to the reflector 3 in a defined manner.

[0035] The reflector 3 is arranged such that it reflects a part of the light from the light source 1 and couples it out to the front of the motor vehicle lighting device 5 in particular, so as to provide the desired light distribution. The first of the two functions of the motor vehicle lighting device 5 is thus achieved.

[0036] The light-transmitting part 2 includes a reflection part and a refraction part ( figure 1 not shown in ), the reflective portion and the refractive portion exist at least on the surface of the light-transmitting p...

Abstract

The invention relates to a vehicle light, having at least the following: a light source (1) comprising at least one LED; a translucent part (2) disposed such that it receives light from the light source (1); and a reflector (3) disposed such that it reflects part of the light from the light source (1), and decouples toward the front of the light (5), which passes through the translucent part (2),wherein a reflection section and a refraction section are provided within the translucent part, the reflection section deflects the light emitting from the light source by total reflection to a direction extending substantially perpendicular to the optical axis of the reflector (3), and the refraction section decouples the light in the direction of the reflector.

Description

technical field [0001] The invention relates to a lighting device for a motor vehicle comprising at least: a light source including at least one LED; a light-transmitting portion arranged such that the light-transmitting portion receives light from the light source; and a reflector arranged In order to make the reflector reflect the part of the light from the light source and pass through the light-transmitting part and couple the part of the light to the front of the lighting device; a reflective part and a refracting part are equipped in the light-transmitting part, wherein the reflective The part deflects the light emitted from the light source by total reflection into a direction substantially perpendicular to the optical axis of the reflector, and the refracting part couples the light out in the direction of the reflector. Background technique [0002] Such a motor vehicle lighting device may have at least two functions, a first function characterizing the light leaving...
