| 20160374273 | Daisy Chain Grow Light - An improved ceramic discharge (hanging) lamp is designed for growing plants. A top mounted quick disconnect ballast provides maximum reflection area around the bulb. This also provides a quick disconnect for maintenance. Multiple ballasts can be daisy chained from one high voltage receptacle. An augmented LED or other light source can be attached to a lower frame or to the top frame to provide added light colors at various growth stages. A controller can vary the cycle times of each augmented light panel. The primary reflector maximizes the efficiency of the bulb. | 12-29-2016 |
| 20160377259 | Asymmetrical Optical System - An asymmetrical optical assembly employs reflecting surfaces and a lens to combine the light from a plurality of LED lamps into an illumination pattern useful in a floodlight or work light. The reflecting surfaces and lens optical element are not symmetrical with respect to a plane bisecting the optical assembly and including the optical axes of the LED light sources. Some light from the LED light sources is redirected from its emitted trajectory into the desired illumination pattern, while a significant portion of the light from the LED light sources is permitted to exit the optical assembly without redirection. Minimizing the number of optical elements employed and the redirection of light enhances the efficiency of the resulting light assembly. | 12-29-2016 |
| 20160377261 | ADJUSTABLE RETROFIT LED TROFFER - A direct troffer-style fixture for solid state light sources for use in these fixtures. Embodiments of the present invention provide a direct troffer-style fixture that is particularly well-suited for retrofit structures. The fixture comprises a retrofit troffer assembly that is removably attached within a T grid or pan structure. The retrofit fixture can be installed in two pieces: a first including a lens structure, a back reflector and 2 end reflectors; and the second component including a second portion of the back reflector. An interior space created by the lens structure houses light emitters and in some embodiments, a light engine and/or additional electronics. One or both of the end reflectors may be movable, slidable and/or rotatable, to accommodate installation. The back reflector covers most of the interior surfaces of the troffer fixture to direct more light out of the fixture. | 12-29-2016 |
