A relocatable add-on control sensor module is described which electrically connects and controls at least one recessed light fixture. The add-on control sensor module includes a sensor ethernet socket that may be electrically connected by an ethernet cable to a light fixture ethernet socket of the at least one recessed light fixture so that the add-on control sensor module may control the at least one recessed light fixture.

A fluorescent luminaire has a luminaire housing, a lens frame positioned within the luminaire housing, the lens frame having a first side frame member and a second side frame member connected to a first end frame member and a second end frame member, a flexible plastic lens having a length, wherein a distance between the first and second side frames is less than the length of the plastic lens and, wherein the lens curves from the flat orientation to a curved orientation when seated between the first and second side frames corresponding to curvature of the first and second end frames.

An air-handling luminaire comprises a recessed troffer housing having a first pair of opposed walls and a second pair of opposed walls, the housing having a light output opening and a lens extending across the light output opening, at least one of the walls of the first pair of opposed walls and the second pair of opposed walls being substantially vertical and having at least one flow through opening for fluid communication from a volume beneath the recessed troffer housing to a plenum above the recessed troffer housing and, a rail extending from near a lower edge of the recessed troffer housing upwardly within the recessed troffer housing and adjacent the at least one flow through and concealing the at least one flow through opening.

Luminaire

An air handling luminaire having a light diffuser, louver, or lamp shield made of a flammable material and mounted within a luminaire housing. Integral with the luminaire housing is a heat distortable support clip from which the light diffuser, louver, or lamp shield depends. The luminaire housing also has a ballast channel and at least one reflector mounted therein. The ballast channel and luminaire housing have a plurality of vents and air gaps for fluid communication with an air plenum. The heat distortable support clip non-permanently deforms or distorts when introduced to a predetermined temperature in order to release the lamp shield from the housing and prevent burning thereof.

Luminaire housing

A fluorescent lighting fixture utilizing a printed circuit board as an electronic ballast. The printed circuit board ballast includes outlet pins which are directly mounted and connected to the lampholders, thereby to minimize or eliminate a number of wires running between the ballast and lampholders.

The apparatus is a modular medical lighting system which includes a ceiling-mounted reading light module, examination light module, ambient light module, and a night light module. The reading light is directed toward a selected reading area on a hospital bed directly below the medical lighting system. The examination light illuminates the entire top surface of the hospital bed. The ambient light directs light to a wall abutting the head of the hospital bed thereby providing reflected light to the vicinity of the hospital bed. The night light directs light to a selected side of the bed so as to light a nurse's medical chart clipboard without disturbing the patient. The modules may be provided separately or in combination.

Modular medical light system

A fluorescent light fixture is provided to illuminate a rearwardly adjacent wall. An upper reflector reflects light from a forwardly offset fluorescent light bulb in a downwardly and rearwardly oblique direction to illuminate lower areas of the rearwardly adjacent wall. A lower reflector with an upper edge directed substantially toward a central portion of the fluorescent light bulb reflects light substantially horizontally to illuminate uppermost area of the rearwardly adjacent wall where the wall abuts the ceiling. A throttle plate controls the amount of lamp exposed to the lower reflector for intensity control. A glossy white series of reflective surfaces approximating an involute curve gathers output from the fluorescent light bulb for redirection from the specular portion of the upper reflector without hot spots or striping on the wall. The lamp is rotationally positioned to maximize the amount of output controlled by the optic system. A vertically adjustable mounting plate adapted to conventional grid-type ceilings formed by ceiling member rails is provided.

The apparatus is a modular medical lighting system which includes a ceiling-mounted reading light module, examination light module and ambient light module. The reading light is directed toward a selected reading area on a hospital bed directly below the medical lighting system. The examination light illuminates the entire top surface of the hospital bed. The ambient light directs light to a wall abutting the head of the hospital bed thereby providing reflected light to the vicinity of the hospital bed. The modules may be provided separately or in combination.
