A lighting apparatus is provided that includes a bulb housing having a first surface, and a second surface, wherein the first surface is at an angle greater than zero degrees, but less than or equal to forty-five degrees from a second surface, and wherein the second surface is parallel to a plane on which the bulb housing is to be mounted, and a receptacle connected to the first surface. A quad-tube fluorescent bulb is accommodated within the receptacle. When the angle has a value of forty-five degrees, three tubes of the quad-tube fluorescent bulb are exposed and seventy-five percent of the lighting produced by the quad-tube fluorescent bulb is direct light and twenty-five percent of the lighting produced is indirect or reflected light.

International Classification:
H01H 13/04
US Classification:
174058000
Abstract:
In accordance with one embodiment of the present invention, a fastener holding bracket is provided. In some embodiments, the fastener holding bracket includes an attaching portion configured to attach the fastener holding bracket to a mounting tab; and a holding structure attached to the bracket configured to hold a fastener when the fastener is placed in the holding structure. In accordance with yet another embodiment of the present invention, a method of positioning a fastener with a mounting tab is provided. In some embodiments, the method includes aligning fastener holding structure on a fastener holding bracket to a hole on a mounting tab; and positing a fastener in the fastener holding structure.
A combination heater-light-ventilator unit for mounting in a ceiling, is disclosed. A cylindrical housing supports the unit and an annular grille on its bottom includes an arcuate heat discharge outlet around part of its circumference and an arcuate air intake through the remainder, with a light diffuser supported in the center. The heat discharge outlet is configured to direct heat flow relatively straight down from the unit to minimize its recirculation through the arcuate air intake.
Two thermal protectors or thermostatic sitches are mounted on the outside of the housing of a combination ventilator/lamp unit to sense any heat build-up in the housing during operation of its lamp. One switch is normally open and is connected between the lamp and the motor for the ventilator fan; and the other switch, which is normally closed, is connected in series with the fan motor and lamp. The normally open switch is set to close automatically when the temperature in the housing reaches a first value above room temperature, thereby to energize the fan motor to cool down the housing. If the normally open switch and/or the fan motor fails the normally closed switch is set to open at a temperature above that at which the normally open switch closes, and functions as a safety switch to disconnect both the fan motor and lamp from the power supply.
The housing has therein two wire inlet/outlet openings overlapped by opposite ends of a removable, generally L-shaped knockout cover, which has in one end an access opening registering with one inlet/outlet opening, and in its opposite end a knockout plug which covers the other inlet/outlet opening, but which can be removed if both inlet/outlet openings are to be used. A wiring chamber is formed in the housing in communication with the inlet/outlet openings by a removable right-angular cover element which cooperates with the housing walls to form a chamber which is triangular in cross section.

US Classification:
362149
Abstract:
The assembly includes a grille, a lamp housing (reflector) containing a lamp socket, and a lens. These parts are releasably attachable to each other by a pair of flexible tabs which project upwardly from the lens at opposite sides thereof, and by a pair of rigid tabs which project upwardly from opposite sides of an external flange which surrounds the lower end of the reflector. The lamp housing extends upwardly through a central opening in the grille, and the flange on its lower end engages the underside of an internal flange formed on the grille around its central opening. The rigid tabs on the lamp housing overlie the flange on the grille to secure the housing to the grille, and the flexible tabs on the lens extend through registering notches in the housing and grille flanges, and have hook-shaped upper ends which overlie the grille flange releasably to secure the lens beneath the reflector.
