摘要： A lighting apparatus for use as a surgical headlamp is disclosed. A light emitting diode is positioned in a recess within a frustoconical, thermally-conductive heat sink that has a several circumferential ridges to provide a desired surface area for heat transfer. The diode and the heat sink are provided in a housing that also includes a fan for drawing ambient air into the housing to contact the heat sink and exhausting heated air. A lens is snap-fit into a slide that frictionally engages the interior of the housing, allowing a user to adjust the spacing between the light emitting diode and the lens as desired. Personal cooling apparatuses usable with the lighting apparatus are also described. Auxiliary undergown switches are also described as are personal cooling apparatuses.

摘要： Lighting applications which are particularly difficult to light because of “non-standard” target areas (or otherwise) would benefit from advancements in lighting design. That being said, conventional wisdom in lighting design has practical limitations—conventional means of visors at/on lighting fixtures (i.e., local visoring) can only become so long to provide beam cutoff before becoming prohibitively heavy or costly, for example. Local visoring can only be pivoted so far before beam shift occurs (e.g., shifting the physical location of maximum candela or photometric center), as another example. Conventional wisdom can only buy so much cutoff and beam control before the overall lighting design is impacted—and so an alternative approach is warranted. One such alternative approach which relies upon a combination of remote visoring and local visoring is discussed; additional approaches are also discussed.

摘要： The T-bar includes an elongate rigid spine extending between terminal ends including either a fixed anchor or adjustable anchor for attachment to adjacent T-bars or other supports. An upper heat sink is provided on an upper portion of the spine to enhance heat transfer from the T-bar to air surrounding upper portions of the T-bar. A light housing is provided on a lower portion of the T-bar which is configured to support a lighting module therein, such as a light emitting diode (LED) light. A lower heat sink is provided above this light housing and integrated into a rest shelf which supports ceiling tiles adjacent the T-bar. A power supply is provided which can be removably attached to the T-bar and provide appropriately conditioned power for the lighting module.

摘要： A lighting test method that includes connecting a housing including driver electronics and a junction box to a main power source. The main power source is connected to a main power connector in the junction box. The driver electronics includes a first terminal. The method further includes connecting a power testing module to the first terminal to the driver electronics to determine whether the main power source is correctly connected to the main power connector in the junction box. The method further includes replacing the power testing module with a second terminal of a light engine housing. Connecting the first and second terminals provides that the driver electronics are in electrical communication with a light engine within the light engine housing.
