Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of an optical fiber lighting device according to an embodiment of the present invention. The optical fiber lighting device includes a light source device 1, a lighting device terminal 2 located at a position distant from the light source device 1 to emit light to a predetermined illumination space, and a light source device 1 and a lighting device terminal 2.
And a light guide 3 using an optical fiber for transmitting light by connecting between the light guides. The light guide 3 is preferably made of a heat-resistant glass fiber so that strong light can be collected and transmitted. Specifically, a bundle of a plurality of glass fibers is housed in a flexible tube such as resin or SUS to form a light guide 3. The surface of the glass fiber is coated with special PVC.

FIG. 1 shows an example in which the output light of one light source device 1 is branched into a plurality of light guides 3 and transmitted to a lighting fixture terminal 2. Therefore, the plurality of light guides 3
The base end is combined into one incidence jig 31, and the emission jig 32 is attached to each end. The light source device 1 has one lamp 11 and a concave mirror 12 for condensing the output light of the lamp 11. It is connected to.

The light source device 1 includes, for example, a color filter 14 such as red, blue, and yellow to change the color of the illumination light.
Is mounted near the light collecting section. Irradiation jig 3 attached to the tip of light guide 3
2 is connected to the lighting equipment terminal 2. Lighting equipment terminal 2
May be a single appliance terminal to which a plurality of light guides 3 are attached in a predetermined arrangement distribution, or may be configured as separate appliance terminals separated for each light guide 3.

FIG. 2 shows a specific configuration of the light source device 1. The lamp 11 and the concave mirror 12 are housed in the housing 100 so as to emit light downward as shown in the figure, and are mounted on the vertical wall by the mounting portion 101 in this state. Alternatively, a method of installing on a floor may be used. An incident jig 31 of the light guide 3 is attached to the bottom of the housing 100 so as to receive light from the lamp 11. The lamp 11 is, for example, a metal halide lamp or a halogen lamp, and the concave mirror 12
Is a dichroic mirror.

A cooling fan 103 is mounted above the lamp inside the housing 100. The exhaust port 106 is opened below the cooling fan 103 of the housing 100, and exhaust gas is guided to the exhaust port 106 via a duct 104 extending downward from the cooling fan 103. By attaching the cooling fan 103 and the duct 104 in this manner, it is possible to prevent rain or the like from entering the light source device 1 even when the light source device 1 is placed outdoors.
A filter 105 is attached to the exhaust port 106 to prevent dust and insects from entering. Further, a heat insulating material 107 is attached to an upper portion of the housing 100 and other necessary portions to prevent dew condensation inside the housing 100 after the light is turned off.

The specific configuration of the lighting equipment terminal 2 is determined by what kind of effect lighting is to be performed in accordance with the lighting use of various facilities, stores, general houses, and the like. FIG. 3 shows, as an example, a configuration in the case where the present invention is applied to effect lighting for floors and walls using marble. A marble plate 200 to be attached to a floor or a wall is one lighting fixture terminal. Fig. 3
As shown in the cross-sectional view of FIG. 4, which is a cross section taken along the line AA ′ of FIG.
The thin marble portion remaining at the end of 1 is a translucent light diffusion window 20
It is 2.

The light guide 3 can be directly buried in the concrete floor 301 serving as a base of the marble plate 200 by applying a special PVC coat, and its tip including the emission jig 32 has a concrete floor. It is led out onto a concrete floor 301 through a cylinder 302 buried in 301. Emission jig 3 at the tip of this light guide 3
2 is inserted into the hole 201 of the marble plate 200 as described above, and the marble plate 200 is fitted into the concrete floor 301, whereby a marble floor surface for effect lighting is obtained.

[0015] Such a marble floor surface is completely the same as a normal floor in appearance during the daytime, and there is no lighting equipment in a normal sense. Can be obtained. The floor may have any shape as long as it is translucent and has a light diffusing property. In addition to natural marble, artificial marble, glass, acrylic resin, ceramics and the like are effective.

As shown in FIG. 1, the color of the illuminating light can be selected by incorporating a rotating plate 13 with a color filter in the light source device 1 and controlling its rotation. Specifically, by adjusting the rotation speed of the rotating plate 13, the lighting time of each color, and the like, various effect lighting can be performed.

FIG. 5 shows a configuration example of the controller 4 for controlling the light source device 1 for such effect lighting. CP
A control signal is generated from U401 in accordance with preprogrammed information, and is sent to motor driver 405 via bus 403. The output of the motor driver 405 is sent into the light source device 1 to control a stepping motor 406 that drives the rotating plate 13. CPU40
The power supply 1 is supplied to the CPU 401 via the protection device 402. The power supply voltage is monitored by the protection device 402, and runaway of the CPU 401 at the time of a power supply abnormality is prevented.

A dip switch 404 is provided for externally setting the effect time. By the switching setting of the dip switch 404, the rotation operation mode of the stepping motor 406 is variably set.
, The setting of the rendering time.
The communication input device 407 is used when a plurality of light source devices are controlled by a main controller (not shown), thereby enabling the main controller to remotely set effect lighting for each light source device.

As described above, according to this embodiment, it is possible to illuminate a plurality of places with one light source. In addition, since the light source device and the lighting equipment terminal are separated from each other in distance, the lighting equipment terminal does not generate heat even when the light source generates a large amount of heat, which is suitable for illuminating a heat-sensitive portion. By incorporating a rotating plate with a color filter in the light source device as in the embodiment, it is possible to produce color light emission, and to produce effect lighting of various color combinations. Further, the lamp replacement and inspection can be performed by a light source device remote from the lighting fixture terminal, and the maintenance is excellent. In particular, when a large number of lighting equipment terminals are widely dispersed, intensive maintenance can be performed with one light source device, so that the effect is large. In addition, the light guide protects the optical fiber bundle with a flexible tube and can be bent freely, so that the light guide does not need to be installed at any place and is free from scratches and rust.

In the embodiment, the lighting of the floor and the wall using the marble is described as the lighting fixture terminal. However, other preferable applications utilizing the characteristics of the optical fiber lighting device include an underwater display and a water display. In other words, the light source device is separate from the lighting equipment terminal, and the light guide can be installed underwater, so that it is effective for lighting in an aquarium or other aquarium, or for displaying a sign used by floating in a pool or the like. .
