EP0635744A3

Optical system for light emitting diodes.

Abstract

The diode (13) is incorporated in a fixed manner on the optical axis (14) of a carrier lens (12). The carrier lens (12) consists of a front portion (18) with an outer transverse surface (25), formed concave towards the emitted light, and a longitudinal portion (19) for incorporating the diode (13). The longitudinal portion (19) has its outer longitudinal surface (22) formed concave towards the diode. The concave transverse surface (22) is surrounded by a further outer transverse system. The concave longitudinal surface (22) is arranged to reflect the diode-emitted light rays (30) towards the further outer transverse surface (24), which is arranged to transmit the light rays to the outside in a longitudinal direction.
