In the first position, the light is reflected into the direction of a second projection element to form a projected illumination beam. In the second position, light is reflected into a different direction to not contribute to the projected illumination beam.

  • Patent number: 10570642
    Abstract: An LED ring or light guide for a mechanical or mechatronic closure system that includes an actuating means, such as socket wrench receptacle or swivel handle, which is rotatably supported in a housing or tray. The LED ring or light guide also includes a retaining nut or bearing piece that can be screwed on with the housing or with the tray with the intermediary of a thin wall such as door panel of a sheet-metal cabinet or sheet-metal housing. A light ring surrounds a flange of the housing or of the tray, and a flexible foil is arranged between light ring and thin wall. The flexible foil carries light emitting diodes (LEDs) and relays the light thereof. A closure indicator integrated in the actuating means is achieved in this way.

  • Patent number: 10551023
    Abstract: A multifunction lighthead for mounting to a vehicle includes several groups of LEDs arranged to provide distinct light emission patterns. Each group of LEDs and associated optics are selected and positioned to produce light emission patterns needed to meet lighting standards applicable to the vehicle. Such standards may require wide angle light emission, which is enhanced by supporting groups of LEDs that project away from the vehicle body, enhancing visibility of the lighthead from directions close to a plane defined by the body panel. The projecting support for the LEDs and optics for a wide angle light emission pattern may be employed to support LEDs arranged for ground illumination. Other groups of LEDs in the same lighthead may be arranged with optics to provide area illumination in support of arrest, search, triage or other emergency functions.
