A lighting apparatus is provided with a housing forming a battery housing and a light housing separated via a partitioning wall. A light module is supported by the light housing and includes a heat sink located at least partially within the light housing and at least one LED supported by the heat sink. A battery receptacle formed within the battery housing to slidingly receive a battery pack at least partially into the battery housing. An intake opening is formed within the partitioning wall and an air vent is formed in fluid communication with the light housing. In operation, an airflow passes in thermal contact with the battery pack from the battery housing into the light housing through the intake opening, and from the light housing in thermal contact with the heat sink out of the air vent.

A heat dissipating light fixture includes one or more elongated rows of LEDs extending a length of a light engine, and forming an array having outer and inner perimeter edges. At least one light engine heat sink is conductively coupled to the light engine and disposed adjacent to the array of LEDs. A driver assembly includes a driver that supplies power to the light engine coupled to the light engine in spaced relation thereto, and a driver heat sink is conductively coupled to the driver and disposed relative to the at least one light engine heat sink so as to prevent conductive heat transfer therebetween.

Methods and apparatus for providing circadian-friendly LED light sources are disclosed. A light source is formed to include a first LED emission (e.g., one or more LEDs emitting a first spectrum) and a second LED emission (e.g., one or more LEDs emitting a second spectrum) wherein the first and second LED emissions are combined in a first ratio and in a second ratio such that while changing from the first ratio to the second ratio the relative circadian stimulation is varied while maintaining a color rendering index above 80.

A light emitting device includes a base; a plurality of semiconductor laser elements disposed on the base and configured to emit light laterally from the plurality of semiconductor laser elements; a reflecting member disposed on the base and configured to reflect light from the semiconductor laser elements; a surrounding part disposed on the base and surrounding the semiconductor laser elements and the reflecting member; a wiring part disposed on the base so as to extend to a location outside of the surrounding part; a radiating body disposed on the surrounding part and having an opening; and a wavelength converting member that is located in the opening of the radiating body, the wavelength converting member being configured to convert a wavelength of light that is emitted from the plurality of semiconductor laser elements and reflected upward by the reflecting member.

A recessed lighting fixture comprises a generally annular body having a central cavity in the form of a partially spherical socket. There is a lighting support member having a partially spherical exterior portion which is closely fitted within the partially spherical socket of the annular body. The lighting support member is pivotable relative to the annular body, but air flow between the partially spherical socket of the annular body and the partially spherical exterior portion of the lighting support member is substantially restricted. There may be a light source mounted to the lighting support member adj acent a bottom thereof. The light source may be a light-emitting diode.
