Illumination devices including multiple light emitting elements

A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.

Stern light
11560206 · 2023-01-24 ·

The present disclosure is directed to a stern light for illuminating a watercraft without visually impairing a passenger of the watercraft. The stern light includes a flexible pole with a hollow interior for housing wires. The wires are connected to a watercraft at one end of the pole and to a light source at another end of the pole. The light source, which may be an LED light source, is covered by a globe that at least partially refracts light. When powered, the stern light produces light capable of providing visibility of the watercraft for at least two nautical miles while also avoiding the visual impairment of watercraft passengers. Pole flexibility allows operation of the stern light during watercraft motion and in areas with potential obstructions, such as low-hanging branches.

Braking system for an automated luminaire

A luminaire is provided that includes a head, a movement system, and a control system. The movement system rotates the luminaire head around an axis of rotation. The movement system includes a motor and a braking system. The motor moves a luminaire mechanism. The luminaire mechanism may be a gobo wheel, a lens, or other optical device of the luminaire, or it may be the luminaire head or the luminaire yoke. The control system determines whether the motor is rotating and engages the braking system when the motor is not rotating. When the motor is stopped, the control system may store in non-volatile memory a current absolute position of the luminaire mechanism.
