An optical housing is formed from a blank and a reflector mounting plate. The blank is scored to allow it to be folded into a box with a base and four walls. The box has a circular hole in the base and two wall tabs at the end of each of the four walls. The reflector mounting plate has wall tab slots that receive the wall tabs from the four walls and couples the two parts of the housing together. A set of reflectors is mounted to the reflector mounting plate in a predetermined reflector pattern. Another set of reflectors is mounted to the base of the box in a circular pattern. A third reflector fits into the circular hole in the base of the box and is mounted to the base. A light source is attached to the base of the box and extends vertically through a hole in the third reflector and partially beyond the first set of reflectors.

Optical housing with vertical light source

A light fixture including a housing having a longitudinal axis, an open axial end, and a lens door assembly pivotally connected to the housing and permitting the lens door assembly to move between an open position and a closed position. A latch mechanism secures the lens door assembly in the closed position over the open end of the housing. The latch mechanism can include at least one spring clip connected to the housing and engaging a tab of the lens door assembly when in the closed position.

Spring latching mechanism for light fixture

A clamp mechanism secures a lighting fixture to a mounting apparatus. A tenon is inserted into the open end of a mounting pole. A radially expandable element, mounted on the tenon, is adjusted to expand radially outwardly to engage the inner surface of the mounting pole. Radial outward expansion of the expandable element is imparted by a threaded bolt which threadedly engages a base of the expandable element. As the base is drawn towards the end face of the tenon, angled legs of the expandable element are cammed outwardly until distal ends of the legs frictionally engage the inner surface of the mounting pole.

Expanding tenon clamp

An adjustable mounting assembly, for rotatably coupling a support member with electrical wiring to a lighting fixture housing, has at least one casing with a fastening sleeve for receiving a fastener. The casing also has at least one conduit for receiving the support member and the electrical wiring. A spacer is located between the casing and housing and has a bore for the fastener and an aperture for the wiring. The casing is rotatable with respect to the housing and can be releasably retained in selected rotational positions by the fastener.
