  • Patent number: 9885458
    Abstract: A light funnel collimator has a central lens surface and a back reflecting surface, shaped to provide a wider background beam and a narrower hotspot beam within but off-center of the wider beam. One of the beams is on-axis of the collimator, and the other beam is off-axis. The reflector is at least partly asymmetrical relative to the axis, and provides or contributes to the off-axis beam.

  • Patent number: 9541272
    Abstract: An explosion-proof LED module has at least one light-emitting diode, a heat sink connected to this and an LED cover that covers the LED at least in the emission direction. The LED cover extends into an insertion recess of the heat sink. In this insertion recess, the LED cover is surrounded by a casting compound resulting in sealing of the LED relative to an outer and possibly explosive atmosphere. As a result, an explosion-proof LED module can be provided whereby the manufacture of said explosion-proof LED module is relatively simple and possible in an economic manner in a short time from prefabricated parts. At the same time, the explosion-proof module is furthermore characterized in that sufficient cooling corresponding to the ignition protection type “intrinsic safety” and an embedding of the component according to ignition protection type “encapsulation” are given.
