The invention is directed to a linear luminous body comprising: a light source; a light source accommodating portion in which the light source is accommodated; and a light guide held by the light source accommodating portion so as to extend from the light source accommodating portion; wherein a light emitted from the light source is introduced into said light guide through an end surface of said light guide.

Linear luminous body and linear luminous structure

A planar light emitting device has a planar light emitter. It has a layered structure composed of a transparent body and a semi-transparent body. The transparent body is made of a transparent synthetic resin containing no light scattering material. The semi-transparent body is made of a semi-transparent synthetic resin containing a light scattering material. The transparent body and the semi-transparent body are joined to form a diffusion layer therebetween. An LED array is disposed at one side of the planar light emitter. The diffusion layer has a sea-islands structure. An island resin has a dimension of 0.1 to 50 microns. The light entering the island resin attenuates therein without reflecting at once due to its complicated shape. Namely, the light entering the diffusion layer generates uniform brightness.

Planar light emitting device

The illumination device comprises at least one light source, and a light pipe positioned at the front side of a license plate, and a light diffusing means. A light of the light sources is led, the light pipe emitting a leading light from the surface of the license plate face. The light emitted from the observed face is diffused by the light diffusing means. The light diffusing means is provided with, rugged portions of an observed face opposite to a light emitting face, or, a light diffusing layer composed of two or more kinds of light transmitting materials, refractive indexes of which are different each other, on the observing face, and a light led from a light leading face is reflected and diffused on the light diffusing layer.

Illumination device

A fluorescent tube is constituted by a fluorescent tubular body having a transparent glass tube coated with a fluorescent layer containing a fluorescent material on its inner surface, and an ultraviolet LED substrate inserted in the fluorescent tubular body and having an equal length to the fluorescent tubular body. The ultraviolet LED substrate has twenty-four ultraviolet light emitting devices each having a long life, and the left end of the ultraviolet LED substrate is connected with lead wires through which electric power is supplied. Accordingly, when ultraviolet rays are emitted from the twenty-four ultraviolet light emitting devices, the fluorescent layer emits light in its own fluorescent color, the fluorescent tubular body as a whole emits light and the surroundings are illuminated with the light. Hence, the fluorescent tube can be used for illumination. Alternatively, the fluorescent tubular body may be formed by a transparent silicone rubber which can be bent into any desired shape.

Fluorescent tube with light emitting diodes

A short-wave light transmitting diode lamp unit has a printed circuit board disposed in a housing. A plurality of short-wave light emitting diode chips is mounted on the printed circuit board so that a light emission side of the light emitting diode chip faces an opening of the housing. An outer glass as a light transmitting plate is attached to the opening of the housing. The outer glass is made of a glass material having high ultraviolet ray transmittance. The outer glass is prevented from degradation caused by the ultraviolet rays. Thus, the light output efficiency is kept in good level and long lifetime is assured. An overall structure becomes simple, thereby reducing the production costs.

A direct lighting unit fits in opposition to an opening of a roof of a vehicle's cabin so as to illuminate a light directly the cabin. An indirect lighting unit is disposed around the outer circumference of the direct lighting unit. The indirect lighting unit contains a plurality of LEDs disposed at fixed intervals so as to emit light outward. The LEDs are controlled to indirectly illuminate the roof. When the direct lighting unit is mounted to the roof, a fixing piece supports a grooved edge portion of the indirect lighting unit so that the indirect lighting unit is immovably held between the fixing piece and the roof. Thus, the direct and indirect lighting units are simultaneously secured to the roof.

A passenger-cabin lighting device comprises as follows. A transparent member is made of synthetic resin not containing scattering material, and has a light emitting surface and a light reflecting surface. A semitransparent member is made of semitransparent synthetic resin containing the scattering material. The semitransparent member is bonded to an inside of the transparent member to constitute a light emitting body. A plurality of light emitting diodes are diposed on one end face of the light emitting body for projecting light into the transparent member and the semitransparent member. A control circuit controls flickering of the plurality of light emitting diodes. The thus constructed passenger-cabin lighting device may be used for lighting and illuminating the passenger cabin, and for highlighting the car itself.

Provided a vehicle exterior lamp capable of illuminating the ground surrounding a vehicle. When returning to a predetermined position of a parking lot, a road or the like where a vehicle has been parked, a switch of a transmitter is operated. By doing so, the vehicle is illuminated in a predetermined color and a selected mode, and the vicinity of a door of the vehicle is illuminated by this light, so that the condition of the ground can be confirmed. Particularly, the color of the light, emitted from a light-emitting source, can be arbitrarily set, and the setting can be made, taking the brightness and the saving of the energy into consideration. Even if discriminating information, such as a code, is not provided between the transmitter and a receiver, the color of the illumination of the vehicle can be discriminated from that of other vehicles.

Vehicle exterior lamp

An information indicating device having an LED and a light transmitting structure is disposed within a line of sight of a vehicle operator so as to transmit light from the LED to the vehicle while the operator is driving the vehicle. A distance sensor measures a distance between a vehicle body and an object near it. An emission control circuit controls the LED based on an output of the distance sensor, thereby indicating predetermined information, such as a distance warning to the operator. An indicating portion is disposed on an end of a corner pole or a fender marker to receive light from the LED and transmit light to the vehicle operator without requiring the vehicle operator to substantially look away from the direction the vehicle is traveling or a mirror showing the driver the vehicle's traveling direction.

Information indicator for vehicle

An LED display device has an indicator having a housing. The housing has at least one incident portion which receives light from at least one LED. The incident portion has a reflection surface at its inside surface. LEDs emit light from one side or one longitudinal end of the incident portion. A refraction plate may be provided to direct emission of the incident light for viewing by a user.

A photo-catalyzer for deodorizing, cleaning, sterilizing, and water purifying operations includes a substrate, a titanium dioxide film disposed on the substrate and functioning as a photo-catalyst, and a light-emitting diode disposed adjacent to the titanium dioxide film and producing ultraviolet light having a wavelength from 360 to 400 nm onto the titanium dioxide film. The photo-catalyzer can be used in places where there is no sunlight because it is optionally provided with a light-emitting diode. The light-emitting diode does not require a large installation space because it is an extremely small light-emitting device. Hence, the photo-catalyzer has a compact structure and can be used easily anywhere, including small places. The substrate can be fabricated into a variety of useful appliances to take advantage of the strong oxidizing properties of the photo-catalyzer. Devices comprising a photo-catalyzer may be used for deodorizing, destroying or repelling micro-organisms, and including undertaking air or water purification.

The inner hose member is disposed substantially coaxially in the outer hose member, includes a second bellows-like tubular portions in the area corresponding to the first bellows-like tubular portion of the outer hose member, and adapted to form a tubular air layer between the second bellows-like tubular portion and the first bellows-like tubular portion. Because of the outer hose member and the inner hose member, the hose exhibits a high flexibility, a reliable barrier ability against gasoline fuels or the like, and an improved adiabatic ability and anti-flammability for the inner hose member.

Hose

A fuel additive pipe 11 comprised of a pipe main body 12 and a plating layer 13 formed on the external or interior wall surface of the pipe main body 12 and composed of an electroless plating layer 131 and an electroplating layer 132. The pipe main body 12 contains a high-density polyethylene as a base material and an additive 21 such as mica. While the pipe main body 12 is subjected to an etching treatment, the additive 21 does not dissolve in the etching solution, so that the additive 21 protrudes from the surface of the pipe main body 12. The thus protruding additive 21 serves as the starting point for forming the electroless plating layer 131 and promotes growth of the layer 131. This electroless plating layer 131 is firmly bonded with the pipe main body 12 by chemical absorption to the additive 21 from which inactive sites are removed by the etching treatment as well as by the physical absorption to the fine roughness formed by the etching treatment on the surface of the pipe main body 12.
