DISCLOSURE OF THE INVENTION According to the present invention, the outer diameter of the tip or the central portion of the bulb is larger than the outer diameter of the bulb base embedded in the ferrule and the screw-type ferrule. A fish collecting lamp comprising: a lamp holder body that is connected to a power source and that has a lamp cap holder inside; and a tube holding member that is screwed at the base to the outer peripheral portion of the lamp holder body. A method for holding a fish collecting lamp is characterized in that the tube holding member fixes the tube portion of the fish collecting lamp via a metal coil spring formed in a ring shape.

To briefly describe the features of the present invention, a ring-shaped metal coil spring is used in place of the silicone rubber used as a member for contacting and holding the bulb of the fish collecting lamp. is there.

The present invention will now be described in detail with reference to the accompanying drawings. A typical configuration of the method for holding a fish collecting lamp according to the present invention is shown in FIG. 1 by taking as an example a mode in which a metal halide lamp having a cylindrical tube which has been used in recent years as a fish collecting lamp is used.

The fish-collecting lamp 101 has, as a basic configuration,
The outer diameter of the tip or center of the bulb 102 is made larger than the outer diameter of the bulb base embedded in the ferrule 103, and is composed of a screw-type ferrule 103. The configuration is the same as that of the conventional fish light 201. However, as described above, in recent years, there is a tendency to decrease the volume of the fish-collecting lights in order to increase the number of the fish-collecting lights to be mounted on the ship. In this case, as shown in FIG. There is a tendency to use a cylindrical tube with a reduced amount of heat. The method for holding a fish-collecting lamp of the present invention is particularly suitable for holding such a fish-collecting lamp in which the degree of expansion of the bulb is reduced (that is, a fish-collecting lamp that easily becomes high in temperature due to less heat dissipation). Of course, it is also effective for holding a fish collecting lamp which is used more and has a bulb having a high expansion degree as shown in FIG. The fish collecting lamp may be a metal vapor discharge lamp such as a metal halide lamp, a halogen lamp or the like, and the material of the bulb may be quartz or glass.

The basic structure of the fish-collecting lamp (holding device for the fish-collecting lamp) 104 is similar to that of the fish-collecting lamp that has been conventionally used, and the lamp holder main body 105 and the lamp holder main body 105.
The tube holding member 107 is screwed to the outer peripheral portion of the ring-shaped base portion 106. Both the lamp holder body and the lamp holder body are preferably made of metal such as aluminum or FRP. However, both need not be made of the same material, and the outer surface may be painted.

The lamp holder body 105 includes a power cord 1
It is connected to a power source (not shown) by 08, and a lamp base holder 109 is housed and fixed therein. A screw 110 is provided on the outer peripheral portion of the lamp holder main body 105.
Is provided while the base 1 of the tube holding member 107 is provided.
A screw 106a corresponding to the screw 110 is cut on the inner side of 06, and by rotating the lamp holder main body 105 and the bulb holding member 107 relatively in the opposite directions, the bulb holding member 107 is formed. Are screwed to move up and down. That is, by utilizing this rotation, the tube holding member 107 is relatively moved upward, and the lower part is the base 103.
The lower side of the bulb expanding portion of the fish collecting lamp fixed by the lamp holder main body 105 can be pressed by the upper portion thereof.

The tube holding member 107 has a threaded portion 10 inside.
A ring-shaped base 106 having 6a, and a ring-shaped (or disc-shaped disc having a circular hole in the center) 114 provided on the top of the ring-shaped base 106 through several columns 111 standing upright from the ring-shaped base 106; It consists of A groove 115 is provided on the inner peripheral portion of the ring-shaped holding portion 114, and a metal coil spring 112 formed in a ring shape, which is a characteristic requirement of the present invention, is attached to the groove 115. The coil spring 112 is made of a heat-resistant material such as stainless steel and can function as a cushioning material when it comes into contact with the lower side of the expanded portion of the tube, so that the fish collecting lamp is exposed to strong wind. It responds softly to the rolling of the tube that occurs when it is struck or the rolling of the ship,
Even if such a rolling occurs, the fish collecting lamp can be reliably retained. Further, since the coil spring has high heat resistance as described above, the deterioration of the holding material, which was likely to occur when silicone rubber was used as the holding material, and the deterioration of the cushioning effect due to the deterioration are effective. Can be avoided.

The coil spring 112 may be attached to the tube holding member 107 in advance, or may be attached below the inflating portion of the tube of the fish collecting lamp. In the latter case as well, on the inner peripheral portion of the ring-shaped holding portion 114 of FIG.
By providing the groove 115, the coil spring attached to the tube can be accommodated in the groove 115, and even in that case, it is possible to retain the same high heat resistance and cushioning effect.

A disk-shaped cover (having a circular hole at the center) made of silicone rubber or another heat-resistant rubber material is provided on the top of the lamp holder main body 105 as in the conventional fish-lamp holder. ) 113 is desirable. By installing this disk-shaped cover, it is possible to prevent the splashed seawater or rainwater from entering the periphery of the base 103. However, this disc-shaped cover 113
Preferably has a vent hole in order to prevent seawater and rainwater slightly entering the inner part (around the base 103) from condensing.

Alternatively, the disc-shaped cover 113 may be in the form of a bellows made of a metal plate. That is, by making the disc-shaped cover also made of metal, even if the temperature of the fish-collecting lamp further rises and the disc-shaped cover may be deteriorated, the fish-collecting lamp can be held more reliably.
