However, because the incandescent light bulb gets so hot, the outer cylinder of this lighting device also becomes quite hot, and if a worker wearing a film radiation protection suit accidentally comes into contact with this lighting device, a hole may be formed in the protective clothing. However, there was a problem in that the work had to be immediately stopped to change clothes and undergo a radioactivity test, which was quite time-consuming.
この考案は、このような問題点に鑑みてなされ
たものであり、その目的とするところは、照明中
発熱した熱を発散させフイルム製防護服が損傷し

にした照明具を提供しようとするものである。 This idea was created in view of these problems, and its purpose is to dissipate the heat generated during lighting and cool the film protective clothing to a temperature below 60°C without damaging it. It is an object of the present invention to provide such a lighting device.

In order to achieve the above object, the lighting device of this invention consists of a socket with a closed rear end that supports the rear end of the umbrella, and an outer cylindrical body with open ends at both ends that supports this socket, and an electric motor for cooling is installed behind the socket. A fan is arranged, a gap is formed between the socket and the outer cylindrical body, and a rod-shaped heat insulating support is attached to this gap to connect the two.

In this lighting fixture, even when the socket is heated by an incandescent light bulb, a large amount of airflow blown from the rear end of the outer cylinder by an electric fan flows into the gap formed between the outer cylinder and the socket. The cooling air blows through the front end opening of the outer cylindrical body and efficiently cools the entire outer cylindrical body. Also,
In addition to forming this gap, a connecting rod-shaped insulating column is placed in this gap so that it is exposed to the constantly flowing air flow, so that the heat of the socket is less likely to be transferred to the outer cylindrical body.

Figures 1 to 3 show an embodiment of this invention, which consists of a socket 2 to which a light bulb 1 is attached, and a cylindrical outer body 3 with openings at both ends that supports this socket 2. Socket 2 inside the cylinder
An electric fan 4 for cooling is attached to the rear of the socket 2, and a gap 5 for heat insulation and ventilation of a required distance is provided between the socket 2 and the outer cylindrical body 3, and three pairs of ultra-thin supports 6 are screwed into this gap. has been done.

向けて導く。 A rear end of an umbrella consisting of a cylindrical cap 8 and a cylindrical portion 9 of the socket is attached to the socket 2, and the cylindrical cap 8 with a protective wire mesh 7 on the front is screwed onto the cylindrical portion 9. There are many small ventilation holes 1 in the cap 8 and the cylindrical part 9 of the socket to promote heat dissipation.
0's are punctured regularly. Further, the rear part of the socket 2 is closed, and the airflow is guided toward the outer cylinder 3.
外筒体３には、前方に円筒形キヤツプ１１が螺
着され、後方にはソケツト用電源コード及び電動
フアン用電源コード１２が貫通している。 A cylindrical cap 11 is screwed onto the outer cylindrical body 3 at the front, and a socket power cord and an electric fan power cord 12 pass through the rear.
なお、この外筒体は使用時適宜な形状の取付具
によつてビデオカメラに取付けられる。 In addition, this outer cylindrical body is attached to a video camera using an appropriately shaped fitting when in use.
電動フアン４は、アーム１３を介して筒体１４
に支持されており、外筒体３の中にすつぽりと嵌
入される。 The electric fan 4 connects to the cylindrical body 14 via the arm 13.
It is supported by the outer cylindrical body 3 and is completely fitted into the outer cylindrical body 3.
支柱６は、極細の金属ねじ棒から形成されてお

い。 The support column 6 is formed from an extremely thin metal threaded rod, and is constantly exposed to strong winds from an electric fan, so that heat from the socket is dissipated here and is difficult to conduct to the outer cylinder. Note that it is preferable to use a nonmetallic material with low thermal conductivity as this support.
第４図は、この考案の他の実施例を示すもので

触しても安全である。 When using the above lighting equipment, even if the socket is heated by an incandescent light bulb, a large amount of air flow blown from the conduction fan flows into the gap formed between the socket and the outer cylinder, making the outer cylinder more efficient. Furthermore, by forming this gap and placing a strut that connects the socket and the outer cylinder in this gap so that it is exposed to the constantly flowing air flow, heat is removed from the outer cylinder. is constructed so that it is difficult to conduct, and the outer cylinder is heated to 60℃, for example.
The temperature is kept below, so it is safe for this outer cylinder to come into contact with film radiation protection clothing during inspections inside the reactor of a nuclear power plant.

This idea is structured as described above, so
During use, the outer cylinder does not get too hot and the temperature is kept below the required temperature, so it can be used, for example, for inspecting the inside of a nuclear power plant's reactor.
Even if the device is carried by a worker wearing protective clothing made of highly fused film and comes into contact with the protective clothing, there will be no trouble such as holes in the film and it is safe. It is also useful for lighting in narrow spaces such as shop windows, and for lighting in fresh food markets where temperature rises are a concern.
