Abstract:
1. A LED rear lamp, comprising a housing; a plurality of LEDs for emitting light; a light guide arranged in, at or forming part of the housing; the light guide having a plate-like shape being designed to guide a first portion of the emitted light to escape through at least two opposing outer side faces of the light guide and to reflect or scatter internally, while traveling towards the two opposing outer side faces, a second portion of the emitted light, such that the second portion of the emitted light escapes through a main surface, the main surface extending between the two opposing outer side faces; a second side opposing the main surface and at a least portion of the second side having a saw tooth profile to reflect impinging light outward through the main surface, the sawtooth portion formed of a plurality of prismatic structures extending outward and away from the second side, each of the prismatic structures having a normal face directed towards at least a portion of the plurality of LEDs, each of the prismatic structures face being substantially normal to at least a portion of the plurality of LEDs; said light guide having a central aperture surrounded by an inner side face of the light guide; the LEDs being arranged in said central aperture such that a main emission direction of such LEDs is aligned towards the inner side face, to couple the emitted light through the inner side face into the light guide, and being aligned towards the two opposing outer side faces, to guide the first portion of the emitted light directly towards the two opposing outer side faces; said light guide being arranged in, at or forming part of said housing such that the emitted light escapes out of the housing through the two opposing outer side faces and said main surface.
