Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a light source used for cold light illumination of an optical fiber, and more particularly to a light source for an optical fiber which can be easily and continuously switched to a spare lamp when a lamp is cut.

[0002]

[Prior art]

 Conventionally, an illumination device having only one lamp has been used as a light source for an optical fiber. In such a conventional device, if the lamp burned out during use, it was necessary to turn off the power once and replace the lamp with a new one. Moreover, the lamps that had been used up to that point were still hot, so there was the inconvenience that they could not be replaced with bare hands.

In particular, in recent years, optical fibers have come to be used in a wide variety of applications, and among these, it is not allowed to interrupt the irradiation of light to the optical fiber for a long time for lamp replacement. There are several things.

[0004] For example, when used for medical purposes, it may even be life-threatening for a patient if it takes a long time to replace the lamp.

[0005]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide an optical fiber light source that can continuously and easily switch to a new lamp when a lamp burnout occurs.

[0006]

[Means for Solving the Problems]

 For the above purpose, a plurality of lamp sockets are arranged along the outer peripheral surface of the rotatable turntable, and the lamp socket at the optical fiber irradiation position can be switched to another lamp socket by rotating the turntable. And a fixing means for fixing the lamp socket to the irradiation position of the optical fiber.

[0007]

[Action]

 According to the present invention, when the lamp in use runs out, it can be switched to a new lamp simply by rotating the turntable, so that the light irradiation to the optical fiber can be continuously used without interruption. It becomes possible.

The burned lamp can be easily replaced with bare hands because it can be removed and replaced with a new lamp after sufficiently cooling at a position deviated from the optical fiber irradiation position.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing an example of an optical fiber light source according to the present invention, in which 1 is an apparatus main body, 2 is a rotatable turntable, 3a and 3b are lamp sockets, 4a and 4b are lamps, 5a and 5b. Is a magnet (fixing member), 6 is a switch, 7 is an optical fiber connecting connector, and 8 is a handle for rotating the turntable.

In the state shown in FIG. 1, the turntable 2 is fixed by the magnet 5b so that the lamp socket 3a, and thus the lamp 4a, is located opposite to the optical fiber connector 7, the switch 6 is turned off, and the lamp 4a is turned off. Is set to light up. When the lamp 4a is burnt out, the handle 8 is turned to the right and the turntable 2 is rotated in the direction of arrow a.

Then, as shown in FIG. 2, the lamp socket 3b, and hence the new lamp 4b, is positioned so as to face the optical fiber connector 7, and in this state, the turn table 2 is fixed by the magnet 5a. At the same time, the switch 6 is pushed by the turntable 2 to be turned on, the lamp 4b is turned on, and the current to the lamp 4a is cut off. In the state shown in FIG. 2, after the lamp 4a has cooled, it is replaced with a new lamp to prepare for switching when the lamp 4b in use is cut off.

Next, when the lamp 4b is cut off in FIG. 2, the handle 8 is turned to the left and the turntable 2 is rotated in the direction of arrow b, the state shown in FIG. 1 is restored, and the switch 6 is turned off. Becomes Along with this, the lamp 4a is turned on and the current to the lamp 4b is cut off. In this way, if a lamp runs out, it can be continuously and easily replaced with a new lamp.

In the above embodiment, the turntable 2 is provided with the two lamp sockets 3a, 3b (lamps 4a, 4b), but the present invention is not limited to this. If necessary, three or more lamp sockets (lamps) can be provided.

Further, the switch 6 and the magnets 5a and 5b are not limited to the above examples, and any switch and fixing means can be used as long as they have the same functions as the above.

[0015]

[Effect of device]

 According to the present invention, when a lamp burnout occurs, it is possible to switch to a new lamp continuously and easily, and it can be continuously used as a light source for an optical fiber without interrupting the irradiation of the optical fiber. it can.
