Light transmission tubes

A light transmission tube includes a tubular clad and a core section having a higher refractive index than that of the tubular clad. A belt-like reflecting layer is formed between the tubular clad and the core section, extending in the longitudinal direction of the tubular clad, in a manner such that a light passing through the core section is reflected and scatterred by the reflecting layer and then emitted from an outer surface area of the tubular clad, which outer surface area is located opposite to one side of the tubular clad where the reflecting layer has been formed. Further, the reflecting layer may be so formed that a light is allowed to be emitted in a plurality of directions. Moreover, the belt-like reflecting layer may be formed into a spiral configuration. The width of the belt-like reflecting layer may be changed in the longitudinal direction of the light transmission tube. The tubular clad is allowed to have a non-circular cross section. The clad formation material may contain an ultraviolet light shielding material or an ultraviolet light absorbing material.

Illumination device and input unit with illumination device

A recess portion is formed in a substrate to accommodate a light emitting element so as to be sealed with a sealant. A light guide layer formed of a thin transparent resin film is fixed onto the substrate via an adhesive layer to realize an illuminating device with a thin structure. The light emitted from the light emitting element is irradiated into the light guide layer via the sealant and the adhesive layer. The light fully reflecting on the boundary surfaces between the light guide layer and the adhesive layer, and between the light guide layer and the air layer passes inside the light guide layer. Then the light which has not fully reflected leaks outside from the surface of the transparent resin film which forms the light guide layer. This makes it possible to illuminate the surface of the illumination device 1A entirely with brightness.

Vehicular lamp employing led light sources

A vehicular lamp employing a plurality of LED light sources and arranged to emit light using indirect illumination wherein the total light emittance in the front direction of the lamp is increased by more effectively using the light from the LED light sources. The LED light sources are arranged in a line in the vertical direction such that their direction of light emission is toward the rear of the lamp. The reflecting surface of the reflector is divided into right and left reflecting areas by a boundary line. With this arrangement, a large portion of the light from each LED light source contributes to the light reflected by the reflector. The reflecting areas are divided into a plurality of small reflecting surfaces, preferably two for each LED light source. Thus, it is possible to separately control the reflection of the light from each LED light source by the small reflecting surfaces on both sides of the LED light sources. When the lamp is observed from the front, the number of illuminated areas is greater than the number of LED light sources.

Key sheet

Disclosed is a key sheet efficiently diffusing local heat generated by a device mounted on a board. A key sheet has a base sheet formed of a rubber-like elastic material in which a heat conductive filler is mixed. Thus, if a semiconductor device on a board generates heat, it is possible to suppress local heat storage by the heat conductive filler of the base sheet. Further, there is no need to provide a separate member for heat diffusion between the board and the key sheet, making it possible to realize a reduction in thickness. Thus, with the key sheet, it is possible to meet the requirement for heat diffusion to eliminate local heat storage in electronic apparatuses, and the requirement for a reduction in the thickness and weight of electronic apparatuses.
