摘要:
A light-emitting diode arrangement having at least one light-emitting diode chip (1), each light-emitting diode chip (1) being assigned at least one optical element (4). In addition, the light-emitting diode arrangement has at least one heat-conducting element (13) which is suitable to carry away the heat generated by the light-emitting diode chip, and at least one cooling apparatus which is suitable to carry heat away from the heat-conducting element. The light-emitting diode arrangement is particularly well suited, for example, to use in motor vehicle headlamps.

摘要:
A motor-vehicle headlight is specified, having at least one light-emitting diode, and an apparatus for controllable manipulation of the beam path of the electromagnetic radiation emitted from the light-emitting diode. The described motor-vehicle headlight is distinguished inter alia by a particularly variable emission characteristic.
摘要:
A motor vehicle headlight element is specified which has at least one light-emitting diode and at least one control apparatus. The control apparatus is suitable for processing a signal which is dependent on a measurement variable and for applying a current corresponding to the signal, to the light-emitting diode. The control apparatus and the light-emitting diode are arranged on a common mount.

摘要:
An LED array comprising at least two LED chips (2) contains a temperature sensor (3), and means are provided for regulating the operating current of the LED chips (2) as a function of the temperature detected by the temperature sensor (3). This makes it possible for the LED chips (2) to be operated for long periods at high operating current, thereby reducing the risk of thermal overload.
