Abstract: 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 of illumination and a plurality of light sources arranged in a pattern having an extension along a horizontal axis. The light emitted by the plurality of light sources has directional components in two opposite horizontal directions along the horizontal axis and a directional component in a vertical direction perpendicular to the horizontal axis. The reflective surface has a curvature such that the directional component in the vertical direction is directed towards the general direction of illumination, and the directional component in at least one of the horizontal directions upon reflection in the reflective surface is substantially unchanged by the reflection.

Abstract: In one embodiment, an LED bulb includes a plurality of metal lead frame strips, including at least a first strip, a second strip, and a third strip. First LED dies have their bottom electrodes electrically and thermally connected to a top surface of the first strip. Second LED dies have their bottom electrodes electrically and thermally connected to a top surface of the second strip. The top electrodes of the first LED dies are wire bonded to the second strip, and the top electrodes of the second LED dies are wire bonded to the third strip to connect the first LED dies and second LED dies in series and parallel. The strips are then bent to cause the LED dies to face different directions to obtain a wide emission pattern in a small space. The strips are then enclosed in a thermally conductive bulb having electrical leads.

Abstract: The present invention relates to a LED rear lamp comprising a light guide (1) arranged in or forming part of a housing (10), said light guide (1) having a plate-like shape with a central aperture (2) surrounded by an inner side face (9) of the light guide. One or several LEDs (3) are arranged in the central aperture (2) such that a main emission direction of each LED (3) is aligned towards the inner side face (9) to couple emitted light through the inner side face (9) into the light guide (1). The light guide (1) is designed to guide a first portion (5) of the emitted light to escape through at least two opposing outer side faces (4) of the light guide (1) and to internally reflect or scatter a second portion (6) of the emitted light traveling towards the two outer side faces (4) to escape through a main surface (7) of the light guide (1). With the proposed LED rear lamp a good rear and side visibility is achieved in an efficient manner.
