Abstract: A light emitting diode (LED) module having a configurable LED substrate capable of receiving varying numbers and layouts of LEDs are described herein. The LED substrate includes LED coupling points for receiving the LEDs and electrical traces etched into the substrate for routing power to the LEDs. The LED module can include a multi-LED over-optic having multiple over-optics that are configured to match the number and configuration of the LEDs positioned on the substrate. The LED coupling points and over-optics can be arranged symmetrically to enable the LED module to be rotated to adjust the light output distribution and direction. The LED module can include a power connection mechanism, for example located at the center of the substrate, that also allows the LED module to be rotated. One or more of the LED modules may be mounted on a heat sink and incorporated into a light fixture.

Abstract: An edge-lit lighting device includes a light emitting panel (LEP), a first plurality of light sources, and a second plurality of light sources. The first plurality of LEDs are positioned proximal to a first narrow side of the LEP and are configured to emit a first light into the LEP through the first narrow side. The first light has a first intensity level. The second plurality of LEDs are positioned proximal to a second narrow side of the LEP and are configured to emit a second light into the LEP through the second narrow side. The second light has a second intensity level that is different from the first intensity level. The first intensity level and the second intensity level are set to achieve a particular distribution pattern of an output light emitted out through a broad side of the LEP.

Abstract: A gasket for an interface between a light emitting diode (LED) and a light emitting panel (LEP) includes a first segment and a second segment. The gasket also includes a first blade extending out from a surface of the first segment and a second blade extending out from a surface of the second segment. The surface of the first segment faces the surface of the second segment.

Abstract: The present disclosure provides air-tight mechanical valves. In a general embodiment, the valves include a shaft and a segmented sleeve. The shaft includes a plurality of shaft ports distributed around a circumference of the shaft. The sleeve is configured to fit concentrically around the shaft and includes a body having at least two body pieces, at least one internal seal, and at least one set of a plurality of sleeve ports distributed around a circumference of the body. The plurality of sleeve ports cooperates with the plurality of shaft ports to facilitate fluid flow. The valves of the present disclosure advantageously reduce losses of pressure and compressed air during use.

Abstract: Present embodiments provide a light fixture having rotatable light modules and an extendable hinged mounting assembly. The light modules are electrically coupled to the light fixture via a cord and a grommet/bracket feature which provides strain relief and a waterproof barrier. The extendable hinged mounting assembly allows the light fixture to be mounted onto a ceiling or other structure while providing a mounted position and an install position.

Abstract: A light emitting diode (LED) lighting fixture has monitoring and control circuits that sense when a freezing condition is present that could result in ice and/or snow accumulation on a lens of the LED lighting fixture, thereby reducing the light output therefrom. Heat may be supplied to the lens from a transparent resistive coating thereon, an internal space heater and/or increased power dissipate from the LEDs.

Abstract: A die plate (14) to be used in a foil stamping machine (10). The die plate (14) includes a plate steel back (20) to which there is secured an image layer (21). The image layer (21) is secured to the plate steel back (20) by means of a compressible adhesive (22). Preferably, the adhesive (22) is an acrylic polymer. The image layer (21) is formed of metal such as brass, steel, copper, zinc, aluminium, magnesium, or photo-polymer.
