Abstract: The lighting system is in the form of a light source (1) with a light transmitting element coupled to a central outlet point (2A). This can be set in the centre of a tube (3) with a fountain outlet. The tube is set with the main fountain that is filled with water (W). A further light source can illuminate the water by housing an immersed light transmitting element (2). The light transmitting element can be in the form of a core of either a visions fluid a flexible solid or a gel in a sealed tube. The tube may be used in a range of illumination applications, such as roadside indicators, road vehicle indicator or for general display. ADVANTAGE - Simple to install.

Abstract: The hose has a hollow tubular sheath (1) enclosing a fluid core (20 with a higher refractive index than that of the sheath between 2 and stoppers (3, 4) for entry and exit of the light. The fluid core (2) is filled in the sheath under pressure. Pref. one end stopper is fitted in the end of the sheath and bonded to the latter before filling with the pressurised fluid and fitting the second end stopper. The pressure of the fluid core is at length equal to the ambient pressure at the min operating temp. and remains below the pressure limit of the sheath at the max operating temp. USE/ADVANTAGE - For transmission of light e.g. between light source and front or rear of road vehicle. Prevents penetration of gas into fluid when used over long period of time, for maintaining transparency characteristic.

Abstract: An optical waveguide hose includes a hollow tubular cladding, a fluid core in the cladding, the fluid having a higher index of refraction than the cladding, and sealing plugs mated with opposite end openings of the cladding. In one form, the core fluid is filled in the cladding under positive pressure. In another form, a sheath of a gas barrier material encloses the outer periphery of the cladding. The pressurized fluid core or the gas barrier sheath prevents air from penetrating into the core, allowing the hose to maintain its light transmission function.

Abstract: PURPOSE:To operate illumination of a large area with one piece of light source by projecting and emitting the light from a light source supplied via a light transmission hose with a planar or curved surface light emitting surface and further a large area region. CONSTITUTION:This surface light emitting device comprises the light source 1, the light transmission hose 2 and a light emitting member 3 and is used on the roof of a building 4, etc. The light source 1 emits light of a specific color (wavelength) and the light transmission hose 2 is formed by packing a viscous liquid-like core into a high-polymer clad worked to a flexible pipe shape. Both ends of the clad are closed by transparent windows. The light is totally reflected at the boundary of the core and the clad and the incident light is transmitted to the other end by using the clad having the refractive index lower than the refractive index of the core. The light emitting member 3 is mounted to the advertisement 5 and the light rays of the respective colors supplied from the light transmission hose 2 progress in the core. These light rays partly transmit the inside of the clad without totally reflecting on a part of the inside peripheral surface The right rays are thus efficiently emitted from the outer peripheral surface.

Abstract: PURPOSE:To easily and quickly confirm desired area and destination by making a line shape light emitting means emit or flash light in a specific color. CONSTITUTION:The line shape light emitting means 3 emits or flashes the light sent from a light source 1 via a light transmission hose 2 in line shape from a station entry to a platform along the path of a station, etc., and four diffused light tubes 3A-3D are used at every line of each system. The diffused light tubes 3A-3D are formed with cores made of the same transparent material as that of the light transmission hose 2, and of transparent material with refractive index lower than that of the core. In the diffused light tube 3, the light sent from the light transmission tube 2 advances the core, and total reflection occurs on an inner peripheral surface, however, no total reflection of the light on another inner peripheral part occurs, and the light passes the inside of a clad, and it can be efficiently emitted from an outer peripheral surface to the outside. Also, the light is shielded by mounting an opaque casing on half periphral surface through which no light transmits out of the outer peripheral surfaces of the clad.

Abstract: PURPOSE:To obtain high safety optimum for illumination in a dangerous area easy to generate induced explosion by fire, etc., by supplying light from a light source provided at a place separated from the dangerous area to the dangerous area via a light transmission hose. CONSTITUTION:An incandescent lamp, for example, is used as the lamp adaptive for the one for the illumination of a warehouse 4, and it is housed in a lamp house 1A outside the warehouse 4. The light transmission hose 2 is formed in such a way that a core in viscous liquid shape is filled in a polymer clad worked in flexible pipe shape and both terminals of the clad are sealed with a transparent window. As the clad, the one with refractive index lower than that of the core is used. A light emitting means is to perform the illumination of the warehouse 4 by diffusing the light transmitted on the light transmission hose 2, and a light diffusing tube 3 is used as the means. The light sent out from the light transmission hose 2 advances the core of the light diffusing tube 3 and no total reflection of a part of the light occurs on an inner peripheral plane, and it transmits the clad, then, it is emitted from an outer peripheral plane to the outside with high efficiency.

Abstract: PURPOSE:To freely illuminate the corner part of a room and an external desired part, etc., and to reduce power consumption by performing illumination with minimum one lamp by providing an illumination means which emits and diffuses light transmitted to a light transmission hose in line shape. CONSTITUTION:The light transmission hose 2 is formed in such a way that a core in viscous liquid shape is filled in a macromolecule clad worked in flexible pipe shape and both terminals of the clad are sealed with a transparent window. As the clad, the one with refractive index lower than that of the core is used. The illumination means 3 is formed so as to emit light of specific color sent from a light source 1 via the light transmission hose 2 almost uniformly in line shape, and a light diffusing tube 3 is used in the means. The light sent out from the light transmission hose 2 advances the core of the light diffusing tube 3 and total reflection occurs on an inner peripheral plane on one side. however, no total reflection of a part of the light occurs on the inner peripheral plane on the other side, and it transmits the clad and is emitted to the outside with high efficiency.

Abstract: PURPOSE:To make it possible to display the information of a signal, e.g. yellow flashing and red, blud or yellow display, on a position separated from the signal while interlocking with the signal by displaying the same information as the signal by means of an optical transmission hose. CONSTITUTION:The optical transmission hose 2 is embedded on the position of a pedestrian crossing. One end of the hose 2 is formed as an incident part 3 for receiving light from the signal 1. In the signal 1, a filter 5 to be switched to red and blue is arranged in front of a light source 4 and light passing the filter 5 is detected by the incident part 3. The hose 2 is formed by storing a viscous liquid-like, solid-like, or gel-like core in a flexible high molecular clad having a refractive index lower than that of the core. Light received by the incident part 3 is passed through the hose 2 and the same information as the signal 1 is displayed from the side face of the other end side of the hose 2. Thereby light projected from the crossing becomes the display of red or blue or the flashing light of blue while interlocking with the signal 1, so that walkers can be prevented from missing the display of the signal.
