The heat sink (20) forms a casing for the electronic driving arrangement (30) and comprises a receptacle interface (26) on a front side (F) of the heat sink (20) with a number of first reference elements (27) for coupling the LED element (10) to the heat sink (20) in a defined orientation. The heat sink further comprises a cavity (28) for enclosing at least parts of the electronic driving arrangement (30) and a number of second reference elements (22) for coupling the LED light module (10) to a secondary optic (70,70′). Moreover the invention describes a lighting assembly (80, 80′) comprising such an LED lighting module (1).
摘要:
The invention provides a lamp with adjustable beam cut-off, useful for e.g. vehicle headlamps. The lamp comprises a solid-state light source 1 and a reflector 2, as well as a movable beam limiter 3. To adjust the cut-off, the beam limiter 3 may be moved by an actuator 4. An advantage is that the beam limiter 3 reflects incident light into the emitted beam instead of absorbing it, which increases efficiency. Furthermore, because the reflector 2 and also the beam limiter 3 may be positioned very close to the light source, which may be a LED or a laser diode, they may be flat and very small. Both circumstances ensure that the beam cut-off may be adjusted very quickly.

A lamp module (10) comprises an LED lighting element (18) and an electronic driver circuit (42) for supplying electrical power to the LED element (18). An electrical connector (14) is connected to the electronic driver circuit (42). A bayonet coupling (16) is provided for positioning and locking the module (10) within a reflector (70). A metallic heat sink (30) with a top wall (34a, 34b, 34c) and a side wall (36a, 36b, 36c) has an inner cavity (40), where the electronic driver circuit (42) is located. The LED element (18) is located at the top wall (34)a in direct thermal contact to the heat sink (30). A lighting unit comprises the above-described lamp module (10) and a reflector (70) with a mounting cavity (74). The module (10) is mounted within the cavity (74), so that the light emitted from the LED (18) is reflected by a reflector surface (72) of the reflector (70).
摘要:
An LED module is described with a base 10 made out of a heat conducting material. An LED element (32) is arranged in a cavity (11) of the base. A collimator reflector (70) is formed by reflective surfaces (24, 64, 66a). Three of these reflective surfaces (66a, 66b, 64) are provided on a plastic insert (60) received in the cavity (11). A further reflective surface (24) is provided on the base (10) itself. This surface (24) has a straight border line (50). The collimator reflector (70) is arranged to reflect light from the LED (32) so that a cut-off (72) is formed by the straight border line (50). By thus integrating the cut-off, as the most critical optical element, into the base (10) itself, high accuracy is achieved.
摘要:
A light source comprising a light engine (10), especially with at least one LED and/or at least one laser light emitting element, and further comprising a light guide (11) and an out-coupling structure (12) is proposed. By this, a flexible scheme to tailor the source size and radiation characteristic of an LED- or laser based system is provided. The size and the position of the out-coupling structure (12) can be chosen to be comparable to the size and position of the filament or arc of a conventional light source like an incandescent-, halogen- or gas discharge burner. The disclosed LED/laser light source is retrofit from an optical point of view so that it can replace a conventional light source like an incandescent-, halogen- or gas discharge bulb or burner in an illumination device.

The invention relates to the on-line analysis of meta-data that is received together with a video signal. This analysis results in an adaptation of the lighting surrounding the presentation device (110). One or more characteristics of the meta-data are filtered out and translated into lighting settings of one or more light elements (102, 104, 106, 108), which in turn can contain one or more light sources.
