Abstract: A lighting fixture utilizing a housing surrounding a fluorescent light source. The housing has an aperture defining an edge portion for determining the cutoff angle of light emanating from the source. A first upper reflector is formed on the inner surface of the housing directing light from the source at angles ranging between the cutoff angle and angles less than the cutoff angle. The second reflector, located adjacent first reflector in the housing between the housing aperture and the first reflector, directs light from the source ranging between a selected angle, which is less than the cutoff angle, and at angles less than the selected angle. The result is a lighting fixture which possesses an optical delay in the activation in the second reflector as one approaches the optical axis from a peripheral position.

Abstract: A reflector for an illumination source manufactured by a spin chuck having an edge surface. The reflector includes a body having a contiguous portion composed of an endless outer surface and a reflective endless inner surface. The body further includes an opening communicating with the endless inner surface. The endless inner surface possesses a relatively fine pattern of depressions and protuberances derived from an edged surface of the spin chuck. The edge surface permits release of the body from the spin chuck although the body may be formed into a rounded or curved member.

Abstract: An apparatus for retaining a trim to a lighting fixture utilizing a frame which is fixed relative to a surface at which the lighting fixture is mounted. The frame includes an opening and a surface surrounding the opening. One or more brackets are placed along the frame surface. A movable element of one bracket connects to the trim for support. Retaining of the trim is a accomplished by further fastening of the trim to another bracket placed along the surface surrounding the opening of the frame.

Abstract: A system for testing the electrical integrity of an illuminated exit sign alternately powered by a battery, rechargeable from a source of alternating current power. The system includes an alarm for indicating an electrical failure, precluding the illumination of the exit sign. A circuit tests the presence of battery electrical power for illuminating the exit sign. In addition, the circuitry periodically tests for the provision of adequate battery power to achieve the same function. Moreover, the system periodically tests and retests for adequate recharging of the battery during a preselected period of time and includes an alarm for indicating failure of the recharging system.

Abstract: A trim for a recessed lighting utilizing a carrier having a first member with a flange extending outwardly from the same. The member includes an opening to permit light to pass from a lamp. A yoke is also found in the trim of the present invention and includes first and second legs connected by a bridging member. The yoke includes a mechanism for rotating or folding the same toward and away from the carrier.

Abstract: A universal bar hanger employed for supporting fixtures to a pair of structural bodies. The bar hanger utilizes an elongated section having first and second surfaces with an elongated slot which is formed between first and second surfaces. The slot possesses a selected length and width dimension. An end section possessing a connector for affixing the end section to the structural body is also included. The end section is joined to the elongated section. A protuberance connects to and extends from the first surface of the elongated section and has a first portion with selected dimension that is in excess of the width dimension of the slot, and a second portion with a selected dimension that is smaller than the selected width dimension of the slot.

Abstract: A control mechanism for use with a fluorescent lighting unit having at least first and second lamps utilizing a line switch. The mechanism includes an AC toggle which alternately interrupts and connects electrical power from a source to one of the first and second lamps, only. The toggle is responsive to the successive opening and closing of the line switch. A reset feature overrides the means for alternately interrupting and connecting power source to one of the pair of lamps by connecting power from the source to the second lamp. The reset feature is also responsive to the operation of the line switch.

Abstract: An ON-OFF switch system for use between first and second conductors utilizing a first plate having first and second sides. The second side of the face plate includes an appendage which contacts an arm passing through a second plate. First and second plates slidingly engage one another to operate the arm. The arm is further connected to one of a pair of electrical contact members and is movable to operate contacts of the electrical members.
