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.

LED lamp unit, in particular for automotive lamps

The present invention relates to a LED lamp unit () comprising at least two LED light sources () arranged between a heat sink () and an electrical connector base at two opposing sides of the lamp unit () 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.

A lighting device () comprising an LED-unit (), a collimator () and a housing (), the LED-unit () is rigidly coupled to the collimator () only, so that no substantial forces can be applied to the LED-unit (). A non-rigid heat transferring medium () is provided in a cavity () in the housing (), to dissipate heat, generated by the LED-unit (). The LED-unit () is therefore at least partly contained in the heat transferring medium ().

Lighting device and method for manufacturing same

The present invention relates to a light emitting diode (LED) or a laser diode () with a functional element () mounted on a light out-coupling side of the LED or laser diode () wherein the functional element () comprises a provision () that allows for electrically contacting the LED or laser diode () on the light out-coupling side.

Light emitting diodes and lasers diodes with color converters

The invention relates to a light source to emit a mixture of primary and secondary light comprising an electroluminescent device like a light emitting diode LED or a laser, to emit the primary light into a light conversion element () to convert the primary light into the secondary light, where a first part of the primary light is emitted along a light path with a first conversion factor () for the primary light, and a second part of the primary light is emitted along a light path with a second conversion factor () for the primary light larger than the first conversion factor.
