An illumination device comprises at least one light module () wherein the light module () comprises a circuit board () to which a plurality of groups () of light sources (,,) are applied and a carrier () on which the light module () is fixed. A display apparatus comprising such an illumination device is also disclosed.

Illumination device

Disclosed is a lighting device comprising at least one LED and at least one optical element, wherein the LED and the optical element are aligned with each other by means of at least one dowel pin. A method of making such a lighting device is also specified. The described lighting device is particularly well suited for use in a vehicle headlight.

A light-emitting diode arrangement having at least one light-emitting diode chip (), each light-emitting diode chip () being assigned at least one optical element (). In addition, the light-emitting diode arrangement has at least one heat-conducting element () 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.

In a method of assembling a surface illumination system having an electromagnetic radiation emitting front side, at least one primary radiation source suitable for emitting electromagnetic radiation when operating is disposed on at least one mounting area of a flexible carrier. The flexible carrier has a front side and a back side opposite said front side, the front side of the flexible carrier defines a reference plane. The mounting area of the flexible carrier on which the primary radiation source is disposed is then bent out of the reference plane such that an optical axis of the primary radiation source extends parallel or obliquely to the reference plane. In a further step, at least one light-conducting guide having a radiation emitting front side and at least one incoupling region is disposed on the flexible printed circuit board so that in operation, the primary radiation source emits radiation into the incoupling region of the light guide and the radiation emitting front side of the light guide points in the direction of the radiation emitting front side of the surface illumination system. A corresponding surface illumination system is also described.
