20120314437 | MULTIFUNCTION TAILLIGHT - A multifunction vehicle light has a housing, at least one light emitter mounted within the housing, and a lens mounted in cooperation with the light and the housing. A filter has a first position and a second position, with the first position being in a light path and the second position being out of the light path. The lens has a first portion and a second portion, with the first portion having a first color and the second portion having a second color. In one embodiment, the filter also has the first color; for example red. The light from the lamp appears to be entirely in the first color when the filter is in its first position and the light from the lamp appears in both the first and second colors when the filter is in its second position, with the colors corresponding to the first and second portions of the lens. | 12-13-2012 |
20110292656 | LUMINAIRE COOLING APPARATUS - An outdoor area light has a housing, a light source comprised of a printed circuit board, a plurality of LEDs, and a heat sink. The heat sink is disposed in thermally conductive proximity to said light source to conduct heat away from it for temperature control. The light source and heat sink are mounted in the housing. A passive impeller is mounted on the housing. A separate active impeller is also mounted on the housing. A conduit for air is in fluid communication with the active impeller and disposed to direct cooling air over the light source and/or the heat sink. The printed circuit board and/or the heat sink and/or their mounts have holes through them. The holes define fluid throughways disposed to convect heat away from the light source via air moving through the throughways. The fluid throughways may be sufficiently aligned to establish laminar flow through them. In high heat, the active impeller is engaged to cool the light; otherwise the passive impeller keeps the light cool. | 12-01-2011 |
