  • Patent number: 5951153
    Abstract: A convertible safety torchiere uses a glass-enclosed vertical halogen bulb with a Type A screwthreaded base. The base is screwed into a socket positioned in a frustoconical cup which extends downwardly from the bowl, and a transparent protective dome is mounted on the cup so as to surround the bulb in spaced relationship thereto. A protective funnel spaced from the cup and socket surrounds the cup and socket under the bowl. The Type A socket allows substitution of a standard incandescent bulb for the halogen bulb if desired.

    Abstract: A lamp using a discharge bulb 7 as a dipped-beam lamp LL is arranged in the middle of a triple headlight, and a lighting circuit 23 is arranged in the middle of the headlight. A cord 22 for connecting the lighting circuit 23 and the discharge bulb 7 is short, and the weight balance of the headlight as a whole is stabilized even if the lighting circuit 23 is relatively heavy. Light projected from the discharge bulb 7 expands horizontally toward the auxiliary lamp CL and the main-beam lamp HL, so that the headlight is illuminated as a whole, which in turn improves the external appearance of the headlight.

  • Patent number: 5911494
    Abstract: The present invention comprises a common baseball-type hat or headband, to which is attached a wide angled halide light apparatus or an apparatus containing several halide lights positioned in a wide configuration. The object of this invention is to provide an efficient lighting apparatus which embodies the principles of an adjustable cap or headband worn on the head, to which a battery-powered halide lighting apparatus is attached by the hook and loop concept. The wide halide light(s) requires a small amount of electrical current and illuminates a larger area with a brighter illumination than the customary headlight. Furthermore, the halide lights emit less radiation (in the form of heat) than halogen lights.The design of the apparatus permits diverse tasks to be easily performed, and increases the safety of all movements in the dark. It is particularly advantageous to pilots of aircraft and engineers to illuminate instrument panels in emergency situations when darkness prevails.

The energy is redirected back to the light to provide increased system efficiency. The redirected light is of the wrong polarization and/or wrong parts of the color spectrum. The lamp efficiency is increased because of the optical pumping as well as the reuse (after some downshifting) of the returned light. In one embodiment, a projection system provides an image source or projection engine that includes the improved high efficiency lamp of the present invention.

    Abstract: A lamp especially designed for use with plasma discharge light sources such as neon tubes. The lamp provides secondary reflective surfaces to ensure that each ray of light leaving the neon tube strikes at least one metallic reflective surface so as to reduce the troublesome RF characteristic of the neon tube and reduce the interference with other electronic equipment on board the vehicle.

  • Patent number: 5597224
    Abstract: The present invention is a device which is capable of holding and fixing a trigger lead with firmness and reliability to a reflector without fixing by soldering or screws. This device forms an opening portion in the back surface of a housing for holding the reflector. In this opening portion there is provided an elastic interposing member, and the core wire of the trigger lead is interposed between this interposing member and the reflector. According to this, the core wire can be held firmly by the elastic interposing member, and also the connection state of the core wire to the reflector can be checked. Also, a holding member comprising bar-shaped projections is provided near the interposing member, and the firm fixation state of the trigger lead can be obtained by winding and fixing the trigger lead to this holding member.

  • Patent number: 5586015
    Abstract: A sports lighting fixture having improved light delivery characteristics includes an elongated bare arc tube, high intensity discharge lamp disposed near the apex of a parabolically shaped reflector member. The reflector is constructed of a non-metallic material and by the orientation and positioning of the lamp within the reflector, an essentially oval shaped light pattern is generated. A light transmissive cover is disposed over the open end of the reflector. When projected onto the playing surface of a sports field, the oval shaped light pattern translates to an essentially circular shaped pattern which allows for a more uniform and efficient overlapping of the multiple light outputs at the playing field level. Louvers can be disposed within the reflector to further redirect any high angle light output into a lower angle which is more useful at the playing surface level.

  • Patent number: 5582479
    Abstract: A dual reflector lighting system having a housing, a ballast and a lamp socket connected to receive a gaseous discharge or high intensity discharge (HID) lamp. An outer reflector is mounted to the housing to reflect a portion of light from the lamp. An inner or auxiliary reflector is mounted coaxially with the lamp to reflect a substantial amount of light from the lamp downwardly. The auxiliary reflector is preferably adjustable relative to the lamp. The invention also covers a dual reflector assembly, including an outer reflector and an inner reflector, adjustable relative to each other which is adapted to be mounted to a HID fixture. The invention also covers an auxiliary reflector having a predetermined size and shape adapted to fit within an outer reflector of a HID fixture and preferably includes facilities for adjusting the auxiliary reflector relative to the outer reflector.

  • Patent number: 5575558
    Abstract: A miniature discharge lamp tube holder having clamp, and stake is disclosed. The miniature discharge lamp tube holder snaps to the mid section of a small diameter discharge lamp, and has a stake end that may be inserted into a formed hole in the lamp housing, or may be pressed directly, or with the help of heat, into the body of the lamp housing to thereby securely couple to the lamp housing, and securely clam to the lamp housing. The one piece support is easily installed, and still accurately holds the lamp. The support allows easy insertion and removal of the lamp, acts to dampen lamp vibration, and allows the tube to slide axially during thermal expansion and contraction. The support also minimizes the dark spot caused while holding the lamp, and minimally interferes with projected light.

  • Patent number: 5574328
    Abstract: An automobile headlamp apparatus comprising a direct current driven discharge lamp surrounded by a concave main mirror which confronts a concave spheroidal sub mirror. The main mirror has a first focus point located substantially at a center of a discharge gap of the discharge lamp between the cathode and anode thereof, while the sub mirror has first and second focus points and an opening therein around the optical axis of the sub mirror. The first and second focus points of the sub mirror are arranged to be substantially on the tips of the cathode and anode of the discharge lamp, respectively. A convex lens may be included to condense the light from the main mirror, wherein the main mirror has a second focus point at a focus point of the convex lens. A shade forming a favorable illumination pattern may be included. In one embodiment, a diagonal mirror is inserted between the main mirror and the convex lens to bend the light from the discharge lamp.
