Abstract: A lamp base includes a housing for at least partial accommodation of a carrier for a light source. Two mutually-opposing guide rails are provided in the housing for the form-fitted insertion of the carrier. The technology is particularly applicable to carriers with LEDs as light sources and addresses problems with adhesive or soldered attachment of the light source carrier.

Abstract: An LED multichip module may include a plurality of LED chips, which have electrical terminals and are connected in series via electrical connections, and have a designated operating voltage, wherein at least one short-circuiting connection is provided, which connects two of the terminals or connections electrically conductively to one another, and the short-circuiting connection bypasses at least one of the LED chips or a resistor, with the result that the operating voltage is in the range of between 150 V and 350 V.

Abstract: A lighting system comprising an electric lamp (1), especially a fluorescent lamp, which is provided with a first (11) and at least one second lamp coil (12). The lighting system further comprises an electronic ballast (2) that is electrically connected to the lamp coils (11, 12) and at least two additional light sources (31a to 31c; 32a to 32c) which are interconnected in parallel. The parallel connection (3) of the two additional light sources (31a to 31c; 32a to 32c) are serially connected between the first (11) and the second lamp coil (12).

Abstract: The invention relates to a lamp with a first light source generating white light, comprising at least one fluorescent lamp (2) or an incandescent lamp, as well as a second light source comprising at least one set of light-emitting diodes (4, 5; 300), and comprising a reflector (1) for the light emitted by the light sources, wherein a cooling device (6, 7) for the at least one set of light-emitting diodes (4, 5) is attached to the reflector (1) and is thermally linked to the at least one set of light-emitting diodes (4, 5), and wherein the lamp comprises a translucent and light-dispersing medium (3) in the optical path of the light emitted by the lamp.

Abstract: A lighting device with at least one lamp and at least one reflector, wherein at least regions of a reflective surface of the reflector are in the form of an involute of a circle of a partial element of the lamp.
