Abstract: 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.

Abstract: A backbox is disclosed herein. The backbox can include at least one wall forming a cavity, and a sensor mounting feature disposed on an outer surface of the at least one wall, where the sensor mounting feature is configured to couple to a sensor device. The backbox can also include at least one fixture coupling feature disposed on the at least one wall, where the at least one fixture coupling feature is configured to couple to a complementary coupling feature disposed on a housing of a light fixture. The at least one wall can be configured to extend substantially seamlessly from a portion of the light fixture at which the at least one complementary coupling feature is located.

Abstract: A disk valve construction having relatively movable face to face disk upstream of a sleeve member at an outlet chamber of the valve. The sleeve member includes a truncated conical portion to produce a desired pressure drop, while, at the same time reducing the turbulence of the fluid flow during operation of the valve. The sleeve member is maintained in position by way of pressure of the fluid, thereby avoiding the necessity of epoxy to hold the sleeve member to the valve body. The sleeve can be provided with an end wall with a discharge opening of a predetermined size at the downstream end of the sleeve for producing a predetermined fluid pressure drop.
