A lens system for LED based light fixtures having a substantially coplanar array of LED's with a requirement for a wide angle of illumination. And in particular, light fixtures comprising LED lights used in low bay applications.

A modular LED lamp structure comprising a LED light source of the type mounted on a plate, a heat sink element having a flat face for supporting the LED light source and a central axis perpendicular to the flat face, a mask for locking the light source designed to press the light source itself, keeping it pressed against the flat supporting face of the sink element, means for removably fastening the metal mask to the sink element.

A cable light includes a battery receptacle that is electrically coupled to a first light module and a second light module. The battery receptacle includes a battery port that receives and retains a battery, such as a power tool battery pack. The first light module and the second light module each include a housing supporting a lens, a light emitter such as an LED, a reflector, and a hanger to hang the light modules on a workpiece. The first light module is electrically coupled to the battery receptacle, and the second light module is electrically coupled to the battery receptacle via a connection with the first light module. The battery receptacle communicates electrical power from the battery pack to the light modules to power the light emitters.

A light-emitting apparatus includes a supporting element, a light-emitting device, and a connecting pin. The light-emitting device has a pair of conductive pads and is disposed on the supporting element. The connecting pin is inserted from the side surface of the supporting element and electrically connected to one of the conductive pads. The topmost surface of the supporting element is lower than the top surface of the light-emitting device.

A light puck that attaches to a wire rope tension grid has a top cover with a plurality of slots to receive wire ropes therein and a corresponding bottom cover. There is also a light fixture having a plurality of LEDs disposed between the top cover and the bottom cover, the light fixture aligned with an opening in the bottom cover. A biasing plate is positioned between the light fixture and the top cover and has adjustment screw associated therewith to bias the biasing plate relative to the top cover.

Lighting systems, methods, and devices for protecting human circadian neuroendocrine function during night use are described. Suitable lighting conditions can be provided for a working environment while protecting the circadian neuroendocrine systems of those occupying the illuminated workplace during the night. Lighting systems, methods, and devices can provide substantive attenuation of the pathologic circadian disruption in night workers. Lighting systems, methods, and devices can attenuate the specific bands of light implicated in circadian disruption. LED lighting systems, methods, and devices can provide increased intensity at a different portion of the spectrum than conventional LEDs, providing a useable white light even when unfavorable portions of the wavelength are attenuated by a notch filter. LED lighting systems, methods, and devices can switch between a daytime configuration and a night time configuration, wherein the daytime configuration provides unfiltered light and the night time configuration provides filtered light.
