Active Cooling Systems For Optics
US Patent:
8596826, Dec 3, 2013
Filed:
Aug 23, 2010
Appl. No.:
12/861449
Inventors:
Yaser S. Abdelsamed - Granville OH, US
Raymond C. Rice - New Philadelphia OH, US
Raymond C. Rice - New Philadelphia OH, US
Assignee:
ABL IP Holding LLC - Conyers GA
International Classification:
H01J 61/52
US Classification:
362294, 362373, 362264, 362345
Abstract:
Light engines that include a plurality of light sources each covered with an optic The optic includes a chamber that receives the light source. In one embodiment, tubes connect adjacent light sources. Coolant is introduced into the tubes and circulates into the chamber of each optic, thus removing thermal energy from the chamber. In other embodiments, the light engines include a heat sink provided with channels. Coolant may be introduced into one of the channels, and may then circulate into the chamber of each optic to remove heat generated by the light source from the chamber. The channels provide a fluid path for the coolant to move between the different optics.

US Classification:
362235, 36224901
Abstract:
In some implementations, a light fixture comprises an inner spherical member, a plurality of light emitting elements disposed on the inner spherical member and an outer spherical member substantially encompassing the inner spherical member. In some implementations, the inner and outer spherical members are coupled to a base. In some implementations, the inner and/or outer spherical members are substantially spherical and include a truncated bottom portion that mounts to a base. In some implementations, the outer sphere comprises substantially transparent regions arranged to substantially align with the light elements. In some implementations, the outer sphere is substantially translucent and/or opaque except for the transparent regions.
