  • Patent number: 5865528
    Abstract: The present invention comprises a light fixture including a housing, a light source, means to secure a light source to the housing, a lens and a reflector. The reflector and lens are positioned so as to direct light from the light source onto an unlit side of the housing.The light fixture is normally suspended from the ceiling or attached to a wall. A greater portion of the light from the light source is reflected off the ceiling or wall, whereas a smaller portion of the light from the light source is reflected off the reflector and onto the housing. After the smaller portion is reflected off the housing, the smaller portion and the larger portion are traveling in generally the same direction, thereby reducing the contrast between the housing and the ceiling or wall.The present fixture housing is very shallow, preferably less than about 3" deep.

  • Patent number: 5089944
    Abstract: A box-type planar light-source device has incorporated therein a linear light source and is provided with a reflecting surface and a multi-prism sheet. The reflecting surface has such function that a major portion of a light reflected by the reflecting surface is obliquely incident upon the multi-prism sheet. The multi-prism sheet has its inner surface formed with a group of prisms so arranged as to extend in parallel relation to the light source and having such function that the light incident directly or obliquely in reflection outgoes in concentration toward a predetermined direction. Accordingly, so as to eliminate portion by the fact that the light outgoing at an angle separated from the normal direction converges at the dark portion. A dark-portion removing sheet for eliminating a dark portion at a location immediately above the light source is arranged on the side of the front face of the multi-prism sheet.

  • Patent number: 5038256
    Abstract: A fixture for a fluorescent lamp includes a diffuser panel. The diffuser panel has a frame and longitudinal elements supported by the frame and spaced apart from one another. At least some of the elements are constructed of a material to allow diffusion of impinging light. Preferred materials are translucent or transparent, such as glass or plastic. The diffuser panel also functions as an air diffuser. Provision of a nozzle in the base of the fixture allows air to flow through the panel by a sucking effect created by high velocity forced air flowing through the nozzle. This results in fixture cleaning and temperature equalization. The fixture is particularly adapted to be mounted in a moving vehicle. For this purpose, the panel is designed to be tamper-resistant and to provide easy maintenance. The diffuser panel, when a latch is opened, may be lowered by rotation to provide access to the lamp and ballast.

  • Patent number: 5006966
    Abstract: An elongated cornice lighting fixture in a public transit vehicle coupled with an advertising display panel is mounted above the windows on each side of the vehicle. Light from incandescent bulbs in each fixture is controlled by sheets of reflective optical film to direct the light to the seating area below each fixture and to the display panel associated with the opposite fixture with only minimal illumination of the vehicle floor and windows.

  • Patent number: 4945461
    Abstract: A portable work light including an elongate fluorescent bulb for emitting light when powered from an electrical current source, an elongate, transparent, relatively thick protective shield, a shock absorber within the shield mounting the bulb within the shield in spaced-apart relation thereto against breakage of the bulb from shock or impact. In addition, an elongate, transparent, relatively thin disposable scuff guard is positioned over the shield to protect the shield from scratching and scuffing and which can be replaced when scratched and scuffed to restore full light transmission to the work light.

  • Patent number: 4924365
    Abstract: A lighting fixture has parabolic, asymmetric, adjustable reflectors longitudinally disposed in alignment with the lamps therein. The reflector is attached to the lighting fixture by a fastener and dimpled end plate. Dimpled end plate mounts to the end of reflector, which includes a recessed plate thereon having matching recesses for receiving the dimples. By rotating end plate and reflector with respect to the recessed plate, the orientation of the reflector may be circumferentially varied.

  • Patent number: 4912360
    Abstract: A double filamented lamp with one filament being a back up for the other filament may be formed with two internal capsules enclosed in a single exterior sheath. Each filament is securely positioned away from, and protected from the activity of the other filament. By securely coupling one capsule to the sheath, and the second capsule to the lamp base, both capsules are accurately positioned, and do not vibrate in the exterior sheath.

  • Patent number: 4876633
    Abstract: A lighting unit, especially for a lighting system is described and is characterized by a carrier section which has a flattened elongate cross-section which terminates in acute angles at both ends, with all functional elements being concentrated in the central part which always has the largest vertical dimension. Changes of the dimensions lead, as a result of the selected layout to no substantial change in the outer appearance, so that powerful systems can also be realized with the same shape without impairing the external appearance.

  • Patent number: 4812954
    Abstract: An apparatus for enhancing the beauty of marble by back lighting the marble to thereby cause the majority of the marble to be illuminated while the veins in the marble block the light and thereby stand out from the marble. A tower structure is comprised of marble walls which preferably are no thicker than 1/4 to 1/2 inch and are light colored such as white or light grey. The tower is hollow and further comprises a lighting fixture within it to provide of source of light to back light the rear interior marble walls, and thereby cause the light to shine through the marble surrounding the veins and enhance the beauty of the veins within the marble. The preferred source of lighting is fluorescent.

  • Patent number: 4794502
    Abstract: A stackable louver assembly for light fixtures which can be made of a high strength polycarbonate light transmitting plastic material and which has a sleeve and louver flange molded in one piece so that the sleeve will not be lost or discarded at the job site. The louver assembly becomes self-enclosed. The louver assemblies are made so they can be stacked one on top of the other and fastened with tie rods at desired locations. The sleeve that supports the louver flange is made with a surface that is generally parallel to the longitudinal axis of the assembly, and can be provided with v-type grooves to provide refraction of the light emanating from an interior lamp. The grooves can be molded into the plastic with no increase in cost, and will reduce glare and improve overall performance of the fixture. Likewise, the louver flanges may have surfaces that are provided with refraction grooves, as well.
