Abstract
A light-emitting diode arrangement is disclosed, comprising at least one light-emitting diode (LED) chip with a radiation decoupling surface through which a large portion of the electromagnetic radiation generated in the LED chip exits in a main direction of emission; a housing laterally surrounding the LED chip; and a reflective optic disposed after the radiation decoupling surface in the main direction of emission. The LED arrangement is particularly well suited for use in devices such as camera-equipped cell phones, digital cameras or video cameras.
