PURPOSE:To facilitate plural pieces of concentrated lighting, to enhance power saving effect and to increase vibration resistance by leaking out an illuminating beam out of an optical transmission hose through a light leakage part and a light emitting member, and emitting light locally. CONSTITUTION:A light emitting device is constituted of a light source l, the optical transmission hose 2 and the light emitting member 3. Then, the light source 1 is provided proximately on both ends of the optical transmission hose 2 through a converging means of a condenser lens, etc., and is constituted so as to emit the light into a core through a window on the optical transmission hose 2. That is, in such a case, this device is constituted so that a required position in the optical transmission hose is crushed by the light emitting member 3, and by that a beam from the light source light guided while totally reflecting inside the optical transmission hose 2 is made to enter a crushed part at a critical angle or below, a total reflection condition is destroyed. Then, only a deformed part intensely emits the light, and that is, the beam is taken out of the crushed light leakage part. |
