Abstract

The present invention provides a lamp for a horizontal operating position within a vehicle headlight assembly. The lamp, as seen with respect to the vehicle, comprises a LED light source for emitting light mainly to one side, and a reflective member for shielding front and lower parts of the light emitted by the LED light source and reflecting them to desired directions. The present invention also provides a vehicle headlight assembly comprising such a lamp, and, further, a reflector for shaping the light emitted by the LED light source into a beam, and a shuttle, adjustable between positions to shape the beam into a high beam or a low beam.

First claim

The invention claimed is:

1. A lamp for a predefined horizontal operating position within a vehicle headlight assembly of a vehicle, the lamp comprising:
a reference feature to allow insertion of the lamp into the vehicle headlight assembly in the predefined horizontal operating position;
a LED light source for emitting light to a first or a second side of the vehicle based on an orientation of the lamp based on the reference feature; and
a reflective member for shielding front and lower parts of the light emitted by the LED light source and reflecting the front and lower parts of the light emitted by the LED light source to desired directions based on the orientation of the lamp based on the reference feature.

2. The lamp according to claim 1 , wherein the reflective member is closely located to the LED light source.

3. The lamp according to claim 1 , wherein the reflective member has an “L” shaped or an arc shaped cross section for its reflecting part.

4. The lamp according to claim 1 , wherein the lamp is a LED retrofit lamp and the width of the reflective member is 3 mm.

5. The lamp according to claim 1 , wherein the lamp has an envelope and the reflective member is located inside the envelope.

6. The lamp according to claim 1 , wherein the lamp further comprises:
an other LED light source for emitting light mainly to the other side, and
an other reflective member for shielding front and lower parts of the light emitted by the other LED light source and reflecting them to other desired directions.

7. A vehicle headlight assembly, comprising:
the lamp according to claim 1 ,
a reflector for shaping the light emitted by the LED light source into a beam, and
a shuttle, adjustable between positions to shape the beam into a high beam or a low beam.
