LIGHTING DEVICE FOR VEHICLES

Housing for an electromagnetic radiation emitting optoelectronic component, component and method of making a housing or a component

A housing for an electromagnetic radiation emitting optoelectronic component is specified. The housing comprises a housing base body provided with a recess in which at least one chip mounting surface is disposed. At least one outer surface of the housing base body, disposed on an emission side of the housing and adjoining the recess, is provided with a baffle layer suitable for screening an electromagnetic radiation. An electromagnetic radiation emitting component provided with such a housing and a method of making a corresponding housing or component are also specified.

HOUSING FOR A LIGHT-EMITTING DIODE COMPONENT, AND A LIGHT-EMITTING DIODE COMPONENT

A housing (1) is specified for a light-emitting diode component (2), having a housing cavity (11) within which at least one chip mounting area (33) for a light-emitting diode chip (3) is arranged, and which has an outlet opening (12). According to one embodiment, the housing (1) has inner walls at least at a vertical distance from the chip mounting area (33), which bound the housing cavity (11) at the side and are at a maximum lateral distance (14, 15) of less than or equal to 500 μm from the chip mounting area (33). Furthermore, a housing (1) is specified in which the housing cavity (11) has at least one subarea (13) which is covered laterally by a housing material (17) which bounds the housing cavity (11) at the sides. Furthermore, a light-emitting diode component (2) is described, in particular for a motor-vehicle headlight. © KIPO & WIPO 2009 ...

PROJECTION HEADLIGHT FOR MOTOR VEHICLES

A projection headlight for motor vehicles has a reflector device, a plurality of light sources, at least one of said light sources assigned to the reflector device. A lens device is arranged in front of the reflector device in the main radiation direction. A cover device in the area of a focal point of the lens device has a cover shaft rotatable across the main radiation direction of the rotating axis main source. The cover shaft is provided with a number of glare edges and/or glare surfaces to adjust light distributors having a number of various cut-off lines. The light sources are arranged on a common light source carrier, the carrier extending substantially perpendicular to the main radiation direction and the carrier being configured to fasten onto a flat side of a heat sink.
