A lamp assembly adapted to cast shadow-free illumination over an area. Typically, a lamp assembly includes a plurality of light modules that are disposed in a spaced apart relationship over an area. Desirably, the lamp assembly is arranged to aim the light output of each module for overlapping summation on a target footprint. Modules generally each include a LED light source, a collimating lens disposed at a distal end of the mirror, and a tube disposed between the LED and the collimating lens.

Disclosed herein is an improved dental operatory lamp having an LED light source that directs light to a reflector that in turn reflects the light to illuminate a treatment area. In one embodiment, the lamp is adapted for efficient transfer of heat from the light source and into the environment. In another embodiment, the lamp is adapted to generate a predetermined pattern of light optimal for the treatment area. In other embodiments, the lamp includes structural features that enable the lamp to maintain optimum light intensity and/or temperature. Also, disclosed herein are unique reflector embodiments that intentionally provide a generally smooth surface, without facets, that reflect light at all visible and infrared wavelengths.

A luminaire includes a light emitting diode module, a driver housing, and a hollow connector that connects the driver housing and the light emitting diode module. The driver housing includes a rotatable cap and a driver that provides power to the light emitting diode module. The rotatable cap permits rotation of the hollow connector and the light emitting diode module in order to direct the light from the light emitting diode module in a desired direction. The light emitting diode module includes a plurality of optics wherein each optic covers at least one light emitting diode and at least one vent adjacent to each optic.

A lighting system includes an LED downlight mountable to a ceiling, a driver, and an insulation displacement connector (IDC). Light from the downlight can be faced downward to project light or upward to reflect light off of the ceiling. The driver has an input with a first voltage and an output with a second voltage, the second voltage being lower than the first and being provided through a wire system extending from the LED driver. The IDC connects the downlight to the wire system. The lighting system can be changed from a first to a second configuration by at least one of adding an additional downlight using a corresponding IDC or removing an existing downlight using a corresponding IDC. The second configuration does not significantly affect a desired output range of light from any downlight or any LED circuit of any downlight that remains or preexists from the first configuration.
