Abstract: An automotive LED lamp unit includes a plate-like mounting member, LED light sources arranged on two opposite sides of the plate-like mounting member, and a heat sink. The heat sink includes cooling fins and a tapered portion facing the LED light sources and being connected to one end of the plate-like mounting member.

Abstract: The present invention relates to a LED lamp unit (10) comprising at least two LED light sources (2) arranged between a heat sink (3) and an electrical connector base at two opposing sides of the lamp unit (10) to emit in opposed half spaces. The proposed LED lamp unit can be constructed in a very compact form in order to replace known halogen, xenon and incandescent bulbs without changing the construction of the reflector and mechanical parts in a head lamp or signaling lamp.

Abstract: 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.

Abstract: The present invention relates to an image generating apparatus (1) which comprises an illumination unit (20) having an intermediate face (21, S), as well as an image modulator (30) for generating an image (I). In addition a deflecting means (10) for deflecting a received light beam (L) of primary illumination light (L1) to said illumination unit (20) is provided in order to irradiate said intermediate face (21, S). Said deflecting means (10) is adapted to have—during the process of irradiating said intermediate face (21, S)—said light beam (L) subsequently in time irradiate different portions of said intermediate face (21, S) in order to thereby reduce the speckle effect.

Abstract: An optical device for backlighting a liquid crystal display. The optical device has an optical element. The optical element includes a material body and at least one recess. The recess is formed in the material body and is configured to determine the light distribution of light to be directed towards the liquid crystal display.
