Definitions

  • the light emitting member may be used as combined with optical fibers.
  • the road display apparatus itself is apart from a light source such as a road lamp or the like, light from the light source can be efficiently transmitted to the road display apparatus without loss.
  • the road display apparatus presents a high visibility particularly during the night.
  • the plane condensing plate may be a plane mirror for condensing external light as reflected therefrom, or a Fresnel lens for condensing external light as transmitted therethrough.
  • Fig. 1 shows a road display apparatus according to a first embodiment of the present invention in which the road display apparatus is applied to a pedestrian crossing.
  • a pedestrian crossing 3 crosses a driveway 1 such that sidewalks 2 at both sides of the driveway 1 are connected to each other.
  • Light emitting members 5 rectangular in plan elevation are disposed at suitable regular intervals along both lateral edges of the pedestrian crossing 3.
  • the light emitting members 5 are made of a material having both light absorption properties and directional light-emitting properties, e.g., "STEAL LIGHT" manufactured by Fujitsu Kasei Co., Ltd.
  • Each of the light emitting members 5 has a light absorbing surface 5s (parallel with the paper plane of Fig.
  • Figs. 8 and 9 show a light source for road display apparatus in accordance with a first embodiment of the present invention.
  • a plane mirror condensing plate 31 and a light condensing device 32 form a light condensing unit 33 for collecting external light 34.
  • Optical fibers 35 are shown as an example of light transmission means. One ends of the optical fibers 35 are connected to one end of the light condensing device 32 forming the light condensing unit 33. Reflected light 36 from the plane mirror condensing plate 31 is condensed through the light condensing device 32 and is incident upon the one ends of the optical fibers 35. The light is then transmitted in a predetermined direction through the optical fibers 35.
  • a light amplifier 37 is disposed in the middle course of the optical fibers 35, and an element panel 38 designed for a road display is connected to the other ends of the optical fibers 35.
