发明名称 UNIVERSAL DAYTIME RUNNING LAMP FOR AUTOMOTIVE VEHICLES
摘要 A daytime running lamp (1) for being retrofitted on a road vehicle, comprising a reflector (4) with a reflective surface (5) for reflecting light in a general direction (I) of illumination and a plurality of light sources (3) arranged in a pattern having an extension along a horizontal axis (A). The light emitted by the plurality of light sources (3) has directional components in two opposite horizontal directions (H1, H2) along the horizontal axis (A) and a directional component in a vertical direction (V) perpendicular to the horizontal axis (A). The reflective surface (5) has a curvature such that the directional component in the vertical direction (V) is directed towards the general direction (I) of illumination, and the directional component in at least one of the horizontal directions (H1, H2) upon reflection in the reflective surface (5) is substantially unchanged by the reflection.

主权项 1. A daytime running lamp for being retrofitted on a road vehicle, comprising: a reflector with a reflective surface for reflecting light in a general direction (I) of illumination and a plurality of light sources arranged in a pattern having an extension along a horizontal axis (A) and being arranged to emit light onto the reflective surface, wherein light emitted by the plurality of light sources has directional components in two opposite horizontal directions (H1, H2) along the horizontal axis (A) and a directional component in a vertical direction (V) perpendicular to the horizontal axis (A), wherein the reflective surface, in cross-sectional view along the vertical direction (V), has a curvature reflecting the directional component in the vertical direction (V) of the emitted light towards the general direction (I) of illumination, characterized in that the reflective surface, in horizontal direction, comprises a straight part, maintaining the directional component in one of the horizontal directions (H1) of the emitted light upon reflection, and a curved part, reflecting the directional component in the other horizontal direction (H2) of the emitted light towards the general direction (I) of illumination.
