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: 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.

Abstract: A wall box mounted voltage controller used in conjunction with a remotely located dimmer module for controlling multiple loads. The controller utilizes a printed circuit board structure and a multiplicity of control operators extendable from the printed circuit board structure. Each operator is linked to a potentiometer which in turn generates a electrical signal to control the intensity of the load via the dimmer module. High and low trim mechanisms for each signal are supported to the printed circuit board structure and are readily available for mechanical adjustment.

Abstract: A device for detecting the level of heat generated by a lighting unit utilizing a sleeve possessing an end portion positioned adjacent to the exterior of the housing, an interior portion, and an exterior portion. A thermal protector is positioned at the interior portion of the sleeve at a selected distance from the exterior of the housing. Air is circulated between the exterior portion of the sleeve and the interior portion of the sleeve.

Abstract: A wall box mounted remotely operated voltage module utilizing a low voltage DC control signal which is remotely generated. A power semi conductor device is triggered to deliver a predetermined amount of power from the source of AC electrical power to a load. The AC electrical power is rectified and transformed to produce a low voltage rectified DC signal. A comparator generates a triggering signal to the power semi conductor utilizing the low voltage rectified DC signal and remotely generated low voltage DC control signal as imputs. The comparator also serves as a compensator for changes in the voltage of the AC electrical power from the source.

Abstract: A panel controlling multiple lighting intensities of a multiplicity of lights in conjunction with a remote lighting dimmer module which utilizes operators mechanically movable to operate potentiometers. Each potentiometer is capable of setting an intensity level of a particular light of the multiplicity of lights. A display is also employed which indicates a lighting level of each of the multiplicity of lights associated with each operator and corresponding potentiometer. The operators and display are supported by a chassis which is mountable in an electrical wall box. Information may be stored which defines a lighting scene in terms of an intensity level of each light of the multiplicity of lights which is set by the operators in the chassis. The intensity level information may be retrieved and transported to a dimmer module which sets the intensity level in each light. One scene may be set into the multiplicity of lights while another scene may be previewed on the display on the chassis.

Abstract: A lighting fixture utilizing an electrical lamp connected to an electrical power source. The fixture entails a base member which is rotatably mounted to an object. A body is also provided which supports the electrical lamp. The body includes a first end portion and a second end portion, the first end portion of which rotates in relation to the body. A swivel member supported by the body rotates the lamp which is held to the swivel member.

Abstract: A lighting fixture mechanically connected to an object utilizing a lamp supporting body. The lamp supporting body is rotated about an axis and includes a swivel member having a swivel arm which moves over the exterior of the lamp supporting body. A boss mechanically connected to the object extends outwardly from the swivel arm and is supported for movement with the swivel arm. A lamp is also supported to the lamp supporting body and is electrically connected to a source of electrical power.

Abstract: A luminaire utilizing a source of light which is reflected outwardly from the luminaire by a first and second reflector in side-by-side configuration. The second reflector is also positioned to one side or in surrounding relationship to the source of light. The light from the first reflector is adjusted to reinforce light coming from the second reflector in a predetermined direction.

Abstract: An adapter for electrically and mechanically attaching a lighting fixture to a lighting track which utilizes a body having first and second end portions. The first end portion of the body connects to the lighting track while the second end portion of the body holds the lighting fixture. The body includes a pair of conductors which are each held in a chamber formed by a recess in the body and a door connected to the body. One of the conductors is movable such that it extends further from the body than the other conductor which is compatible with a two circuit lighting track.

Abstract: A circuit for controlling the initiation and operation of a phase control circuit employed in voltage regulation to a load such as dimming lights. The circuit uses a power semi-conductor which is triggered by a "walk-in" circuit. The "walk-in" circuit includes a regulator diode across a diode bridge which stabilizes the output of the load, such as a level of lighting.
