Abstract: The headlight moving apparatus comprises a yaw rate sensor, a headlight position sensor, a vehicle speed sensor, a CPU, and a headlight actuator. The CPU calculates an appropriate headlight turning position on the basis of these three sensor signals. Since the yaw rate sensor can directly detect the vehicle turning motion and direction, it is possible to move the headlights right and left more reliably. Therefore, the adjusted headlights can brighten remote forward road surface when the vehicle runs along a curved road.

Abstract: A light beam intensifier (10) having a paraboloidal reflector (12) a mirror (14) a single light tube (16) and window (18). The mirror (14) is placed forward of the forcal point f of the reflector (12) and has the light tube (16) affixed thereto to be positioned coincident with the focal point f. As the light tube (16) is energized, light rays (52) emanating directly therefrom are reflected from the parabolic reflector (12) to form a first beam path and the forward shining light rays (54) are reflected from the reflective surface (34) of the mirror (14) to be reflected off the paraboloidal reflector (12) to form a composite light beam path (56) having a predetermined pattern.

Abstract: Fluorescent lighting apparatus utilizing a single elongated tubular light source replaces the multiple fluorescent tubular light sources of conventional or prior art fluorescent lighting apparatus. A substantial part of the light output of the fluorescent tubular light source is reflected by an improved reflector construction having multiple elongated strip-like mirror surfaces. A simplied, less expensive, more efficient apparatus is disclosed wherein the improved reflector forms the principal part of the apparatus and is provided with a compact raceway for the current carrying wires along with a remotely situated ballast in a compact enclosure which facilitates the adaptation of the improved apparatus to surface mounting on ceilings as well as recessed mounting of the fluorescent apparatus in suspended ceilings and the like.

Abstract: A combination lamp assembly suitable to be mounted to the rear of a motor vehicle, comprising a lamp housing defining two or more lighting compartments each having at least one light source mounted therein. In one embodiment the front ends of two lighting compartments are closed by respective inner lenses and further by two sections of a common outer lens. One of the outer lens sections is transparent and colored in red. The other outer lens section has alternating transparent stripes and opaque stripes. The transparent stripes are colorless whereas the opaque stripes are colored in red. When the light sources are unlit, the outer lens appears wholly red, due in part to the illusory effect of the opaque red stripes. However, when lit up, the two lamp units project red and white light through the transparent red section of the outer lens and through the colorless transparent stripes of the other outer lens section, respectively.

Abstract: A thermal barrier is interposed between a lampholder assembly and a plug box assembly in a track lighting fixture.

Abstract: A decorative light with rotating reflecting disc is disclosed which includes a mounting base and a translucent dome secured upon the base. A plurality of sockets with lamps are mounted in the base beneath the dome and each socket can contain a lamp of different color. A motor is concentrically secured in the base to rotate a circular reflector below the lamps to reflect light rays from the lamps upwardly against the undersurface of the translucent dome. The surface of the circular reflector is covered with a crinkled or otherwise bent "Milar" sheet to form a great multitude of small, angularly offset reflecting surfaces so that a unique, colored, reflected, light pattern is projected upon the underside of the dome by the rotating reflector.

Abstract: A light pole planter arrangement is set forth wherein a plurality of mirror image shells are arranged for 180 degree containment about an associated light pole such that when the shells are secured together about the light pole, various plants and the like are positionable therein for a novel enhancement of the associated light pole. Each shell is formed with a continuous elongate seal extending along terminal end faces of each shell and continuing about an upper portion of a serrated semi-circular opening within each shell wherein each serrated opening enables a frictional non-slip engagement with the light pole planter device in association with the light pole. Offset tabs are positioned extending outwardly of each end surface of the device for enhancement of the association of the two shells to effect a non-slip arrangement of one shell with respect to the other.

Abstract: A headlight device for use in an automobile and of the type including a lamp body having a recess opening in the front direction, a lens covering the front end of the lamp body, a reflective mirror being formed of a synthetic resin material and tiltably supported between the lamp body and the lens, and a lamp supported on the reflective mirror. The reflective mirror is supported on the lamp body through one rotatable portion and two space adjusting portions. Each space adjusting portion consists of a nut member supported on the mirror and an adjusting rod rotatably supported on the lamp body and having a screw-thread portion for engaging screw-threadingly with the nut member. A bracket is formed on the reflective mirror integrally for supporting the nut member and has a recess in the front side thereof. And the front surface of a wall defining the front end of the recess acts as a part of the reflective mirror.

Abstract: An illumination device for producing uniform illumination of a surface, comprising several parallel optical conductors which are placed above an optically reflecting surface, and whose reflecting outside sheath is removed locally at least in such a way that the light thereby emerging from the optical conductor is reflected by the reflecting surface to the surface to be illuminated. The optical conductors are spaced at such intervals and placed at such a distance above the reflecting surface that the light reflected by the reflecting surface can reach the surface to be illuminated on the other side of the optical conductors through the space between the optical conductors in such a way that the most uniform possible illumination of said surface is obtained.

Abstract: A matrix lamp bank display utilizes individually removable light filtering assemblies that are composed of a rectangular tinted lens and a supporting frame. Each frame is removably mounted to the display at the front of the lamps provided within it. Each lens is inclined from the vertical to reduce sun or external lighting glare. Provision is made to accommodate thermal expansion of the lens and its supporting frame, as well as ventilation of each lens during lamp operation. Multicolored displays can be achieved by grouping two or more lens colors and operating multiple lamps in combination to project a desired color mix about the matrix.
