Abstract

See full text

The present invention relates to a LED lamp unit replacing an H4 bulb in a headlamp. The LED lamp unit (2) at least comprises two LED light sources (5) arranged on two opposing sides of a support member (11) to emit in opposed half-spaces, a heat sink (12, 3) and an electrical connector socket. The electrical connector socket is designed to fit in a lamp holder of a H4 headlamp such that the plane (6) separating the opposed half-spaces is tilted around the optical axis (7) of the headlamp by an angle of between 5° and 30° against the horizontal plane when the connector socket is mounted in the lamp holder. The proposed LED lamp unit replaces H4 bulbs in H4 headlamps and achieves the required legal beam pattern without changing the optical design of the headlamp.
