Abstract:
Embodiments described herein are directed to a lighting fixture including a lightguide that distributes light from a major surface, a light assembly including light sources arranged linearly, and a frame including a means for providing a force that urges the light assembly against an edge of the lightguide. A standoff or spacer can provide an air gap between a light source of the light assembly and the waveguide edge. In various embodiments, the lighting fixture may incorporate a spring, a spring finger, a spring clip, a screw, or other means for securing the light assembly against the edge of the lightguide. In this manner, substantially all light provided by the light assembly is emitted into the edge of the lightguide. The fixture is formed to accommodate tolerances among elements of the lighting fixture, while maintaining the light assembly securely against the edge of the lightguide.

A light emitting diode (LED) lighting system includes a primary enclosure and a secondary enclosure. The primary enclosure can include a fastening feature of a secondary enclosure receiver that is positioned adjacent to an aperture in the primary enclosure. The secondary enclosure can include a corresponding fastening feature that mechanically couples to the fastening feature of the primary enclosure, where the secondary enclosure surrounds the aperture when the secondary enclosure is mechanically coupled to the primary enclosure. The secondary enclosure can further include a passage through which a wire that traverses the aperture in the primary enclosure passes.
Abstract:
Systems, methods, and devices for reducing glare or pixilation associated with LEDs are disclosed. The disclosure relates to a light module that includes a cover panel that reduces contrast in the light emitted by LEDs. The cover panel can be mounted on a substrate which can include a plurality of LEDs. Apertures in the cover panel are aligned each of the LEDs and any optic that may be disposed over each LED. A first portion of the light emitted from the LEDs passes through the optic only and into the environment to be illuminated. A second portion of the light emitted from the LEDs passes through both the optic and the cover panel before passing into the environment to be illuminated. The cover panel can be diffuse and can include various characteristics including textures, objects, and angled surfaces that assist in scattering light.

A system for providing thermal protection for an LED light module and methods for manufacturing the same are described herein. The thermally protected LED light module may include a heat sink assembly thermally coupled to an LED light source, and a thermal protector. The thermal protector may be connected to the heat sink assembly by a mechanical fastener. Further, the thermal protector is electrically coupled to the LED light source and a power source where the thermal protector breaks the power provided to the LED light source from the power source when the thermal protector detects heat at or above a threshold temperature.

A dimming circuit for a light-emitting diode fixture includes a dimming switch, a signal transfer device, and a timer. The dimming switch can include a dimming switch and generate a current at a first voltage level, where the current corresponds to a dimmer setting of the dimmer switch. The signal transfer device can include an input communicably coupled to an output, where the input of the signal transfer device is electrically coupled to the dimming switch, and where the output of the signal transfer device generates a signal at a second voltage level based on the current received by the input. The timer can be electrically coupled to the output of the signal transfer device and to a LED driver, where the timer generates a pulse width modulation (PWM) signal based on the signal, and where the timer sends the PWM signal to the LED driver.
