Abstract: Apparatus for a lighting fixture or luminaire latching mechanism. A lighting fixture's housing (16) is hinged at one end or portion and includes a door (14) which latches to the housing (16) at an opposite end. A latch (12), which contains a mating hook (32), is connected to the housing (16). A latching surface (28) on the housing (16) interlocks with the mating hook (32) when the door (14) is closed. The latch member includes a main (36) and secondary flexing portion (40) with the mating hook (32) therebetween, as well as door push portion (44) and handle portion (42). The door (14) is opened by applying a force to the handle portion (42) which deforms the main (36) and secondary flexing portion (40) to disengage the mating hook (32) from the latching surface (28), as well as pushing or applying a force to the door to help disengage it from the housing (16).

Abstract: According to certain embodiments, an apparatus comprises a housing including a cavity; a socket disposed in the cavity, wherein the socket makes direct contact with a portion of the housing surrounding the cavity; a surge protector disposed on the socket, wherein the surge protector comprises a male interface plugged into the socket, and female interface; and a photocell plugged into the female interface.

Abstract: A universal tiltable joint (10) for a lighting fixture (11) includes a first joint portion (12) having an axial joint axis (A), a second joint portion (14) having the axial joint axis, one of the first joint portion and the second joint portion housed co-axially within the other of the first joint portion and the second joint portion, a co-axial gap (60) between the first joint portion and the second joint portion allowing movement at an angle to the axial joint axis, the movement causing at least one of engagement or disengagement of a safety feature (27) on the first joint portion and the second joint portion.

Abstract: A luminaire heat sink housing (40) which has a lens locking clip (20) which retains the lens (30) against a gasket (50). Both the hinged locking clip (20) and the heat sink housing (40) may be extruded to any desired length and allows the lens be readily removed. The hinged locking clip (20) extends along a side of the housing (40) and lockingly slides into place to bias the lens (30) against a gasket (50) and seals the light engine within the interior of the heat sink housing. The locking clip is removable from the housing and includes a locking clip rotation head, lens retention surface and locking head to affix the lens in position against the gasket and in front of the LEDs (55).

Abstract: The present invention relates to a central vacuum power unit comprising in combination a canister, a chamber for collecting debris, a first plate, a second plate, a third plate, a duct, a motor-fan assembly, a filter, and a first baffle. The duct extends between the first and second plates and is in fluid flow communication with respective openings defined in the first and second plates. The sidewall of the canister, the first and the second plates and the duct defines an acoustic damping chamber covered with a lining of sound absorbing material.
