Patent ID: 8003998

Claim:
An LED arrangement, comprising: at least one LED chip provided with a radiation decoupling surface and having a surface opposite the radiation decoupling surface, wherein a large portion of the electromagnetic radiation generated in the LED chip exits through the radiation decoupling surface in a main direction of emission; a housing laterally surrounding said LED chip, and a reflective optic disposed after said radiation decoupling surface in said main direction of emission, wherein said LED chip is a thin-film LED chip, wherein said reflective optic comprises a light entrance opening through which a large portion of the electromagnetic radiation generated in said LED chip enters, and the area of said light entrance opening is no more than twice that of said radiation decoupling surface of said LED chip, wherein said radiation decoupling surface is one of the main faces of the LED chip, and side faces of said LED chip extend transversely to said radiation decoupling surface.
