Abstract: An electric lamp assembly simulating the appearance of a gaslight for installation in an existing incandescent-type light fixture. The assembly includes an adapter which contains a screw in, incandescent-type base projecting from one surface thereof, and a receptacle for receiving the base of a fluorescent lamp on an opposed surface thereof. The lamp is surrounded by a translucent cover, and a fabric mesh encloses the cover. A wire frame assembly is disposed on the outside of the cover and mesh. The cover includes longitudinally extending ridges which diffuse the light emanating from the lamp, to present an appearance that looks similar to a gaslight. Also, the cover may be provided with a tint which, in combination with the mantle, provides the light emanating from the lamp with a color virtually identical to the color of light which would emanate from a typical gaslight.

Abstract: A glare control lamp and reflector assembly and method for glare control which includes a conventional lamp and symmetrical reflector for providing a controlled light beam to a target area. A reflector shield can be positioned on the reflector below the lamp and has the properties of diverging incident light downwardly towards the target area and thus controls reflection upwardly which would produce glare. A glare shield can be positioned on the top of the reflector and extends outwardly from the outer edge of the reflector to block both direct light and reflected light from traveling upwardly and outwardly which would produce glare. In a further combination, a lamp shield can be positioned over a portion of the outermost extending end of the lamp to prevent unreflected light from directly causing glare.

Abstract: A light collimizing device (10) having a light input unit (11), a first light reflection unit (12), a window unit (13) and a second light reflection unit (14). The light input unit (11) allows light rays (18 and 19) to enter therethrough. Some of the light rays (18) are reflected off of the second light reflection unit (b 14), and some of the light rays (19) are reflected off of the window unit (13). All of the reflected rays (18 and 19) are then reflected off of the first light reflection unit (12) to yield a plurality of collimized light rays (17).

Abstract: A task lighting system is disclosed including a reflector which supports a light source such as a fluorescent light tube. An at least translucent, member covers the light source and extends along its entire length. A variable light transmission pattern is carried by the elongated tube. The light transmission pattern has a density which is directly proportional to the brightness levels of the light source, both longitudinally and circumferentially thereof. The variable light transmission pattern is defined by a plurality of opaque markings and is positionable within the reflector so that the light source has an apparent uniform brightness. The variable light transmission pattern controls veiling reflections which can occur when an observer views a task having a given specularity. The member is movable with respect to the light source to vary the brightness of the luminaire.

Abstract: Lighting fixture having housing with an open side. A lamp is mounted in the housing and is capable of producing light rays which pass through the open side of the housing. A glass protective covering is carried by the housing and encloses the open side. At least one surface of the glass is provided with anti-reflection film formed by a chemical etch/leach process on the one surface. The anti-reflection film increases the transmission of the high angle light rays from the lamp.

Abstract: A transparent hemispherical shield formed of polycarbonate resin protects a light-diffusing lens mounted in an aperture in the door of a conventional streetlight. The shield has an inwardly projecting flange disposed in a diametral plane and defining an aperture of approximately the same size and shape as the door aperture. The shield is attached to the streetlight by resilient return-bent clips having spaced parallel tabs securing the shield flange to the streetlight door.
