Abstract

Day travelling light, in particular for automotive vehicles, comprising a light source in an illumination housing and a means associated with the light source for bundling the light emitted by the light source, wherein the light source comprises at least one LED (13) (FIG. 1).

Claims

1. Day travelling light, in particular for automotive vehicles comprising a light source in an illumination housing and with means for bundling the light emitted by the light source, characterized in that the light source comprises at least one LED (13, 30, 40).

2. Day travelling light according to claim 1, characterized in that it comprises a reflector (31) as bundling means.

3. Day travelling light according to claim 1 or 2, characterized in that the at least one LED (40) is installed in an optics according to the Cassegrain principle.

4. Day travelling light according to any one of the claims 1 through 3, characterized in that it comprises a Fresnel optics (22) as bundling means.

5. Day travelling light according to any one of the claims 1 through 4, characterized in that the day travelling light is disposed in an external mirror (20).

6. Day travelling light according to claim 5, characterized in that the Fresnel optics is disposed in a covering plate of the mirror.

7. Day travelling light according to any one of the claims 1 through 6, characterized in that the day travelling light comprises several LEDs (13) and is disposed around a further illumination means, in particular a low beam, a driving light or a fog light module.

8. Illumination device according to any one of the claims 1 through 7, characterized in that the at least one LED (13, 30, 40) is white.
