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 projection apparatus is specified, comprising a light modulator having a light receiving region with a cross-sectional area to be illuminated of the size AM and a maximum acceptance angle α for incident light, and at least one light source by means of which, during its operation, a light cone is produced for illuminating said cross-sectional area of said light receiving region and which comprises a number N of LED chips having a maximum radiation angle β. At least one of the LED chips has a radiation decoupling area of the size AD. The relation 0.7·(AM·sin2(α))/(AD·sin2(β)·n2)≦N≦1.3·(AM·sin2(α))/(AD·sin2(β)·n2) applies, where n is equal to 1 or to the refractive index of a coupling medium with which the LED chips are provided.
