Abstract: An illuminated bicycle having a body frame, a handlebar and wheels formed of hollow tubular members made of plastic material that allows light to be transmitted radially through their side walls. A high intensity lamp is mounted at a predetermined location within one of the hollow tubular members. A bundle of flexible elongated optical fibers have their one end positioned adjacent the high intensity lamp so that light therefrom would be transmitted through the optical fibers. The optical fibers are threaded throughout the hollow tubular members of the bicycle body frame so that when the lamp is illuminated the hollow tubular members will glow and make them highly visible at night. The lamp may be powered by batteries or a small bicycle generator.
Abstract: The device includes check-up of tire-pressure, depth of tire tread, and illumination components. The device is small, and hence affords drivers the facility of portability, for example, at a key ring.

Each light control part is composed of nine prisms arranged in a 3.times.3 matrix. The central one of the prisms faces a respective one of the light-emitting diodes.
Abstract: A belt for joggers, cyclists and other recreationists, having a forwardly shining light to reveal hazards along the path, along with an insulating, sweat producing liner on the body side of the belt, for maximum sweat production for local loss of fatty tissue. The belt also may be worn, at the option of the wearer, in a folded condition without contact of the body with the insulating material, then no longer serving as a sweat generating device.
Abstract: The present invention discloses a fitting structure of a safety lamp to a wheel especially of a bicycle or motorcycle. Such safety lamp is replaceably mounted on an air valve disposed on the wheel. Due to such construction, people can clearly recognize the presence of the bicycle or motorcycle even from the back or the side, thus enhancing the safety of the rider. Furthermore, the safety lamp can be fitted easily and reliably by utilizing the male screw portion of the air valve of the wheel. The fitting structure includes a skirt which protects the air valve.
Abstract: A light intensity control includes a current control device which delays the application of the maximum level of current to one or more lamps of an illuminated vanity mirror. In the preferred embodiment, the current responsive control device comprises a negative temperature coefficient thermistor coupled in series with the lamps.

Abstract: A vessel adapted to hold a plant and to serve as a light globe facing downwardly; the vessel having an open top and a closed bottom to define a toroidal volume to hold the plant, a central recess opening from the bottom of the vessel and extending upwardly, a light bulb socket at the upper end of the recess, and optionally, vents in the bottom of the vessel and a ring shaped cover for the vents spaced downwardly from the closed bottom.
Abstract: A vehicle lamp device in which the inside of a lamp unit is communicated with the outside while maintaining a water-proof property of the lamp unit itself so that generation of water droplets is prevented. The lamp unit constituted by a lamp body for housing a large number of light-emitting diodes arranged at predetermined intervals in a transverse direction of a vehicle body and a front face lens covering a front opening portion of the lamp body incorporated in a spoiler disposed on an upper surface of a rear end portion of a roof of the vehicle body so that the front face lens is exposed to the outside through an opening portion formed in a rear end surface of the spoiler. A rubber bushing is disposed in the spoiler, and lead wires of the lamp unit are led out to the outside of the lamp unit through a lead-out portion which projects from a back surface of the lamp body and are inserted through lead-wire insertion holes formed in the rubber bushing.
Abstract: A light ray radiation stand comprises a foundation, one or more deformable flexible conduits vertically installed on the upper part of the foundation and an optical conductor cable holding means mounted on the tip end portion of each conduit. The optical conductor cable transmits the light rays therethrough and emits the same from the end portion.
Abstract: A simulative candle includes a housing receiving therein a battery, an oscillator converting the battery power into an a.c. power, a half-wave-rectifying filtering network changing the a.c. power into an astable high-voltage d.c. electric power, and a neon lamp energized by the astable d.c. power to sparkle like a real candle flame.
Abstract: A reflector/refractor device is provided for use with a variety of lighting fixtures and light sources. The reflector/refractor device includes a body having a predetermined profile and defining a cavity with the body having an inside surface and an outside surface. An illuminating source for emitting light is disposed within the cavity substantially along a central vertical axis of the body. The body includes a series of sectional zones for reflecting and refracting light. The exterior surface of the device includes a plurality of substantially vertical prisms consisting of reflective elements, refractive elements and elements that may be either reflective or refractive depending on light center location. These reflective or refractive elements act in combination to selectively vary light distribution characteristics of vertical and lateral angles, and intensities, by vertical displacement of the illuminating lamp source.

Abstract: A plastic lamp housing is molded in one piece with two cantilevers extending forwardly from its rear wall for supporting a metal made reflector and a light bulb out of direct contact with all the inside surfaces of the lamp housing. The reflector thermally covers at least the top and bottom and rear sides of the light source for the reduction of heat transmission to the lamp housing. Depending from the lamp housing, a lamp standard has a hollow extending therethrough in communication with the interior of the lamp housing through a heat release opening formed in the bottom of the lamp housing. The lamp standard is for use in mounting the lamp on a hollow structural part of a motor vehicle in the vicinity of its rear window. Therefore, by creasing an opening in the hollow vehicle part, the heated air within the lamp housing can be vented into the hollow lamp standard and thence into the hollow vehicle part, instead of into the interior of the vehicle body.
