<p>A LED module comprising a LED and a rotationally symmetrical, bowl-shaped collimator lens. Said lens comprises a hole for accommodating the LED. The lens also includes a flat surface through which light from the LED passes. The normal to this emergent surface is substantially parallel to the axis of symmetry of the lens. Said surface comprises a sawtooth-like structure for bending the outgoing light. LED modules of this type can deflect the outgoing light through a certain angle relative to the axis of symmetry of the lens. These modules are relatively cheap and compact.</p> |
