20140111966 | LOW-ANGLE THOROUGHFARE SURFACE LIGHTING DEVICE - A lighting device may include a housing configured to be attached to a thoroughfare surface. The housing may include a top surface, a proximal face, a distal face, and first and second sidewalls extending between the proximal face and the distal face. Circuitry may be carried by the housing. A first primary optic may be carried by the housing adjacent the first sidewall to define a first optical chamber, and a first light source may be positioned within the first optical chamber and carried by the housing adjacent the first sidewall. The first sidewall may have a first slanted section, and an axis of the first slanted section may skew to a longitudinal axis of the lighting device. | 04-24-2014 |
20140177238 | SEALED ELECTRICAL DEVICE WITH COOLING SYSTEM AND ASSOCIATED METHODS - An electrical device and method are presented, the device having an enclosure defining an interior volume sealed from the environment and an electronic lighting apparatus, which may include a heat generating element such as a light source, a heat sink, and a fluid flow generator. The heat sink may be positioned partially within the sealed interior volume and adjacent the heat generating element and transfer heat therefrom. The fluid flow generator may create a flow of fluid to transport heat away from the heat sink and to the enclosure. The electronic lighting apparatus may be carried by the enclosure and partially disposed within the interior volume of the enclosure. The electrical device may further include an optic carried by the enclosure that may cooperate with the enclosure to define the sealed interior volume. | 06-26-2014 |
20140211295 | WAVELENGTH CONVERTING LIGHTING DEVICE AND ASSOCIATED METHODS - A lighting device according to another embodiment of the invention for directing source light within a source wavelength range in a blue wavelength range in a desired output direction may comprise a MEMS device that may include a DMD that includes an array of MEMS cells, each MEMS cell including an operative surface to receive and redirect the source light towards the desired output direction.
