Abstract

PURPOSE:To obtain a fishing light with a sufficiently high light out-put ratio for cooling a lamp by making up a reflector covering the U-metal of the lamp out of a plurality of reflecting plates, and thereby providing each gap between the reflecting plates adjacent with each other. CONSTITUTION:When cross wind (a) hits against the reflector 6 of a lighting equipment from the transverse direction, wind blowing in the lighting equipment from the inlet side 101 of wind with respect to said cross wind (a), flows into the exhaust side 102 of wind in such a way as to go around a lamp 1. In this case, wind flows in such a way that air within the lighting equipment is sucked out because said cross wind (a) flows out alongside the outside surface on the exhaust side 102 of the wind of the lighting equipment. This therefore permits cool air blowing in the lighting equipment from the inlet side 101 of wind to flow out of the exhaust side 102 of wind while cooling the whole of the circum ference of the lamp. The case where a reflecting plate is divided in the longitudi nal direction has been illustrated so far, the same effect can thereby be expected for the case where the reflecting plate is divided in the transverse direction.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of industrial application] The present invention relates to a lighting fixture, particularly a lighting fixture using a large lamp for a fishing lamp.

(Prior Art) Conventionally, as a method of using this kind of lamp, there is a method described in Suisan Sekai, No. 38, No. 2, 1 1 6/1 20. As described in Hayashi Research Institute (1989.2, i5), a method is known in which a large number of such devices are suspended on both sides of a ship.

Fishing lights used for squid fishing range from incandescent bulbs to mercury lamps. Although it has changed over time to metal halide lamps, it has always been used with the lamp 1 attached to a socket 2 attached to a wire (not shown), as shown in Figure 9. Therefore, the light from the lamp is directed towards the L side. The UV rays diffused laterally, making it impossible to efficiently illuminate the sea surface, and workers on board the ship could sometimes get sunburned by the UV rays from the lamps. To prevent this, the 10th
There is also a socket 2 with a reflector 3 attached as shown in the figure, but since the reflector 3 is located above, it is not sufficiently effective and it is difficult to prevent UV rays from the lamp from being applied to workers on board. It was something.

Large metal halide lamps used as fishing lights are
Because they have a high load in order to obtain a large amount of light, they must be cooled by wind and cannot be used inside lighting equipment.

However, when a projection-type device like the one shown in Figure 11 is used as a fishing light, the light from the lamp is efficiently projected onto the sea surface, and workers on board are also exposed to ultraviolet rays from the lamp. However, since projection-type devices are intended to be attached to iron poles, they are heavy and easily blown away by the wind. For this reason, conventional metal halide lamps for fishing lights were difficult to cool down sufficiently with the wind, causing the temperature of the arc tube to rise too much, leading to premature deterioration and defects. [Problems to be Solved by the Invention] As mentioned above, if a lamp is simply attached to a metal halide lamp socket for a collection light, the light will be diffused upward and laterally, resulting in a large loss of light, which will cause problems for shipboard workers. However, the ultraviolet rays from the lamps can cause sunburn, and when using land-based projection devices, they are too heavy and sealed, which can lead to premature deterioration and defects. there were.

This invention was made to solve these problems, and has a high efficiency as a fish-collecting lamp, is lightweight, has little wind resistance, and can cool the lamp sufficiently.
Another object of the present invention is to provide a lighting fixture for a fishing light that can prevent UV rays from the lamp from irradiating workers on board a ship.

(Means for Solving the Problems) Therefore, in the lighting equipment for fishing lights according to the present invention, the reflection covering the base side of the five lamps is made up of two or more reflectors, and there is less light between the adjacent reflectors. Both have some gaps. Further, a lighting device according to another aspect of the present invention is provided with a mechanism in which the reflection lamp rotates coaxially with the lamp.

[Effect]

In this invention, the reflector is divided into two or more pieces, and a space is provided between adjacent reflectors, so that the wind passes through the reflector, reducing the resistance caused by the wind. This works to cool the lamp.

In another invention of the present invention, the wind resistance is reduced by rotating the reflector by the wind, air is sucked through the opening of the reflector, and the lamp is cooled by the wind. work as if

〔Example〕

Below, an example of an actual trip will be explained based on the drawings.

(Embodiment!) FIGS. 1 and 2 show an embodiment of the present invention. The lighting fixture for the fishing light in this example has an opening diameter of 5.
0 0 as, the reflection length is 330 cm.

As shown in FIG. 3, the reflector 6 has 12 reflectors 4
It consists of Reflector plate 4 is thick! It is a trapezoidal aluminum plate, and ,4ABC and fBcD are 90 degrees. A-
Between B is 100ms, between B and C is 460am, and between C and D is 30@s. This reflecting plate 4 is shown in Fig. 1 as A,
Point A of the reflector plate 4 is placed at position B. Attach point B respectively,
The area between A and B is an arc with a radius of 20011 m, and it is fixed to the support frame 7 at point B so that the angle α with the support frame 7 on the outer periphery is 20''. The side is directly attached to the socket 2, and the CD side partially overlaps with the adjacent reflecting plate 4.

The operation of the lighting fixture configured as described above will be explained.

FIG. 4 is a sectional view taken along line m-m in FIG. 1. As shown in FIG. 4, when the crosswind a hits the lighting fixture reflected from the side 6, the wind blown into the lighting fixture from the wind blowing side 101 with respect to the crosswind a will be directed around the lamp l. At this time, since the cross wind a flows on the outer surface of the wind exhaust side 102 of the lighting fixture, a flow occurs that sucks out the air inside the lighting fixture. Therefore, the cold wind blown into the lighting fixture from the wind inlet side 101 flows out from the wind outlet side 102 while cooling the lamp almost all around the lamp.

In the above embodiment, the reflection plate is divided in the vertical direction, but the same effect can be expected when the reflection plate is divided in the horizontal direction as shown in Fig. 7i5.

(Embodiment 2) FIGS. 6 and 7 show another embodiment of the present invention. The lighting fixture for the fishing light in this example has an opening diameter of 5
00as, the reflection length is 330cm.

The reflector 6 is composed of 12 reflectors as shown in FIG. The reflector plate 4 is made of trapezoidal thickness 1■ aluminum plate Tearly, ZABc,! BCD is 90". Between A and B is 1001m, between B and C is 460++n, and between C and D is 30m.
It is s. The A-B portion of the reflector 4 is attached to the position shown in the front view A and H in FIG. 6, and the radius between A and B is 20.
It is an arc of 0 ms, and the angle α with the outer peripheral support frame 7 is 20
” is fixed to the support frame 7 at point B.Reflector 4
The C-D portion is attached to the rotating portion 5 while being twisted so that the angle β is 65° with respect to the vertical center line. The rotating reflector 6 with the reflection is located at the upper part 11
, lower part 12. The reflection plate 4 is twisted at the boundary 13. The upper part is approximately 110 mm wide and the lower part is approximately 220 mm wide. In the upper part 11 and the f section 12 of the rotating reflecting frame 6, the center position of the arc of the bulge of the reflecting plate 4 is changed.

The operation of the lighting equipment configured as above will be explained. As shown in FIG. 8, when the cross wind a hits the rotating reflection of the lighting fixture from the side, the rotating reflection hits the lower part of the lighting equipment 6! 2
Since the reflecting plate 4 has an angle with the outer periphery, it catches the wind and rotates the rotating reflecting plate 6 in the direction of the black arrow. At this time, the reflector plate 4 on the upper part 11 of the rotary reflector 6 rotates in such a way as to blow out the air inside the rotary reflector 6, so that the air heated by the lamp is discharged from the upper part of the rotary reflector 6. It is discharged. In other words, wind flow B occurs. Therefore, cold air is sucked in through the opening of the rotating reflector 6, and heated air is discharged from the upper part 1l while cooling the lamp. This cools the lamp all around.

Using the lighting equipment of this example and a 2 kW metal halide lamp for fish-collecting lights, the lamp shown in Figure 9 is attached to a socket, and the socket with a reflector shown in Figure 10 is used. For each of usage method (■) using the lighting equipment of Example 1 and usage method (2) using the lighting equipment of Example 2, we measured the direct illuminance and the surface temperature of the lamp outer tube, and determined how ultraviolet rays are irradiated assuming that it is on a ship. We investigated this and conducted a lifespan test outdoors.

Directly below illuminance In each usage method, the lamp was lit vertically downward, and the illuminance 4 m directly below the tip of the lamp was measured.

The results are shown in Table 1.

As shown in Table 1, the illuminance in the usage method of ■ is 100
In this case, the usage of ■ is 121.9, which is an example. In the usage method (2), the illuminance is 151.9 and 152.4, which indicates that the illuminance is about 25% higher than in the usage method (2).

10 Lamp outer tube surface temperature When the wind speed is Om/S and 2 m/hour, the surface temperature of the maximum part of the lamp outer tube is measured at 12 points on the circumference at equal angles, and the average value of the measured values is shown. Shown in 2. (Ambient temperature 23℃
) As a result, in a completely windless state with a wind speed of O m/s, Example ■. ■How to use■. Although the temperature is higher than that in the method (2), when the wind speed is 2 m/s, the temperature in the methods (2) and (2) of Examples is 241℃. 237℃, ■,■
It is cooled to approximately the same level of temperature as used in

Even if the lamp receives the same cross wind, in the method of use in Example 3.4, the wind flows around the entire circumference of the lamp to cool the lamp, compared to the method of using ■ and ■ where the wind is directly exposed. Accordingly, as an average value of measurements taken at 12 locations, the usage methods of Examples (1) and (2) provide better cooling.

i) The method of irradiation of ultraviolet rays measured on board the ship.

Fishing lights are hung above both sides of the deck of a ship. Therefore, the methods of use in ■ and ■ cannot protect workers on board from UV rays from the lamp, but the methods of use in Examples It protects you from UV rays and prevents sunburn.

iv) In the usage method of life test ■, ■1■, ■, respectively, 120
A lifespan test was conducted outdoors using individual lamps. As a result, ■. In all usages of ■,■,■,
All lamps had a lifespan of more than 4,000 hours, and Example ■. Sample (■) showed no early deterioration and exhibited similar deterioration characteristics to (■) and (■).

As mentioned above, MfJi. By using a highly efficient reflector, the new lighting fixture can replace the conventional lamp socket 2? Something that is just attached or a normal reflector 3
A higher illumination intensity can be obtained than that using a lamp, and the lamp is cooled as a whole due to the circulation of the wind inside the reflector and the swell caused by the rotation caused by the wind, and the reflection that covers the lamp is Even if Gasa b is used, it does not adversely affect the life characteristics or deterioration characteristics.

In addition, the lighting equipment configured as described above has 6 reflections.
Since the wind passes through the gaps and the wind escapes rather than the rotation, it is less likely to be blown away by the wind.Furthermore, since the reflectors are made of scissors, each of them is light in weight and does not put a burden on the ship. moreover,
Since the lamp is covered with a reflective shield, it can prevent burns caused by UV and I to the music crew on board.
In addition, it is possible to prevent damage to the lamp by preventing collisions caused by collisions between the lamps and damage caused by erect wood.

By the way, in the explanation in E, the case where a reflective glass consisting of 42 reflective plates σ is used is used.
Of course, the reflective canopy can also be used in other shapes. There is also a slit in the reflection. Needless to say, it can be used even if there are only holes, etc., although the effect will be slightly different.

(Effects of the Invention) As explained above, the present invention includes a reflector plate having a diameter of 52 or more and covering the base of the lamp. The spacing at least in part between adjacent reflectors allows wind to circulate through the reflectors, thereby cooling the lamp, providing high efficiency of the appliance, and also protecting workers on board from sunburn due to UV rays. Another invention of the present invention is that the reflection lamp is provided with a mechanism that rotates coaxially with the lamp, so that the reflection lamp is rotated by wind power. The generated wind cools the lamp, which has the effect of providing a lighting device for attracting fish that has high equipment efficiency and protects shipboard workers from sunburn due to ultraviolet rays.
