DESCRIPTION OF THE PREFERRED EMBODIMENTS The following describes the optical fiber lighting equipment system of the present invention in detail with reference to the accompanying drawings showing preferred embodiments.

As shown in Figs. 1 to 3, the optical fiber illuminator system of the present invention has a lamp 22, which is a light emitting member that emits light in the configuration as shown in Fig. 3, mounted through the socket 31. The lamp is installed horizontally in this embodiment, but may be installed in a vertical direction. The lamp is a double-ended type that emits light from both sides and is a metal halide lamp. The light source device portion is also provided with a ballast 26 electrically connected to the lamp 22 in the fixing bracket 30. Such a configuration is clearly shown in FIGS. 1, 2a, and 2b.

Adjacent to the lamp 22, a reflector 35a is provided as a light collecting member that collects light emitted from the lamp 22 in a predetermined direction to send the light emitted from the lamp 22 to the bundle 21 of the optical fiber 20. The reflector 35a The light incident from the lamp 22 may be installed such that the direction in which the light is inclined is directed to the optical fiber bundle 21. The reflector 35a, which is a light collecting member, is mounted to the fixing bracket 30 so as to collect the lamp 22 in a shape that surrounds the lamp 22. The reflector 35a may be changed in shape depending on the lighting purpose, but is generally curved.

Light emitted from the lamp 22 is condensed through the reflector 35a to be transmitted to the optical fiber bundle 21, which is a bundle of optical fibers 20 that transmits light to the irradiation member 29. It is arranged to penetrate through the receiving hole formed on the outer side of the fixing bracket 30 so that light from the reflector is transmitted from the inside of the fixing bracket and by opening the optical fiber port 27 made of an aluminum metal tube having a low heat resistance. 30) inserted and installed. The optical fiber 20 allows light transmitted to the optical fiber bundle 21 to be divided into respective optical fiber ports 27.

The light transmitted to the optical fiber 20 is transmitted to a plurality of irradiation members 29 installed at a position where illumination is necessary through a lighting guide 28 in the form of a cable in which the optical fiber is accommodated, and each irradiation member 29 passes through the optical fiber. Projected through the reflector 35b configured to irradiate the light according to the angle and the bulb 33 serving as a lens for diffusing light, the irradiation member 29 and the lighting guide 28 is a protective cap (32) Is connected through. Bulb 33 is connected to the lighting guide 28 through a protective cap (32).

In addition, a heat shield filter 25 and a blower 23 are disposed in the fixing bracket 30 of the light source device to facilitate heat dissipation of heat generated from the lamp 22. Includes ultraviolet and infrared rays. The thermal cutoff filter 25 is disposed between the reflector 35a and the optical fiber bundle 21 so that only heat is transmitted to the optical fiber bundle 21 without heat. The blower 23 is disposed on both sides of the upper side of the fixing bracket 30. Is installed.

A stabilizer 26 is provided below the lamp 22 in the fixing bracket 30, and a multivibrator 24 is provided adjacent to the thermal cutoff filter 25. This multivibrator 24 acts to blink in order to express colors (colors) with a kind of motor.
