| 20100118525 | Recessed Sealed Lighting Fixture - In an embodiment, a recessed light fixture includes a structural reflector and two end caps that form a light fixture housing. A first, second and third optics areas are provided. At least one first light source type is mounted near the first optics area. A second light source type is mounted near the second optics area and the second light source type is mounted near the third optics areas, the second light source type having a light output level substantially lower than the light output level of the first light source type. A diffuser is configured to sealably mount to the light fixture housing so as to substantially seal an interior portion of the light fixture. In operation, the light fixture can be switch between an ambient mode and an examination mode while providing a cost effective and attractive design. | 05-13-2010 |

| 20140268764 | DOWNWARDLY DIRECTING SPATIAL LIGHTING SYSTEM - A luminaire that includes a plurality of light emitting diodes (LEDs), a light diffuser having a planar surface facing the LEDs, and a reflector that surrounds a cavity formed between the light diffuser and the LEDs. Also disclosed is a light distribution system having a first plurality of lenses configured to convert incident light into a light distribution pattern and a second plurality of lenses configured to convert incident light into a different light distribution pattern. Further disclosed is a method of distributing light that involves emitting light towards a light diffuser, scattering a first portion of the light with the light diffuser, reflecting a second portion of the light with the light diffuser, reflecting the second portion of the light with a first reflective surface back towards the light diffuser, and scattering the second portion of the light with the light diffuser. | 09-18-2014 |
| 20140268799 | LED LIGHT FIXTURE HAVING CIRCUMFERENTIALLY MOUNTED DRIVERS ADJACENT EXTERNAL HEAT SINKS - A light fixture and a housing thereof for managing thermal energy includes multiple cavities separated by a partition wall and each configured to house components of the light fixture, in particular an LED array and LED drivers to power the LED array. The housing further includes a heat transfer flow path radially defined between the first cavity and the partition wall, and a fin in fluid communication with the cavity housing the LED drivers. The heat transfer flow path is positioned for dissipation of heat from the LED array and the fin is positioned for dissipation of heat from the LED drivers. | 09-18-2014 |
| 20150159845 | Luminaire and Improved Lighting System - A luminaire includes a housing defined by a pair of sidewalls, a bottom wall, and a first end wall. The first end wall has a first open-ended slot adapted to receive one or more wires. The luminaire also includes a first bracket removably coupled to the first wall to partially close the open-end of the first slot such that a hole remains. The hole is adapted to securely retain the one or more wires. The luminaire further includes a closure coupled to the housing and configured to close the housing. The closure is configured to include one or more light-emitting components. | 06-11-2015 |
