な避雷効果が確認できた。Next, to explain the above embodiment in more detail, the sodium lamp, that is, the structure 2 has a lamp body 5, and this lamp body 5 is supported by a pole which also serves as the conductor 3. Although not shown, the lamp body 5 houses a sodium lamp inside. 6 is a translucent cover provided facing the lamp. The lightning receiver 1 is a rod-shaped body made of a material based on standards such as JIS H4040, bent into an L-shape, and the base is mechanically and electrically connected to the tip of the pole that also serves as the conductor 3 by a fixing device 7. connected. Next, the operation of the above embodiment will be explained. A lightning strike experiment was conducted to evaluate the case where a commercially available lightning rod was installed and the case where the lightning arrester of the present invention was installed. A commercially available linear lightning rod was used, and the base was fixed perpendicularly to the ground with a fixing device to the tip of the pole (conventional device), as in the case of the present invention. For the conventional device and the device of the present invention, the discharge electrode was positioned 1.5 m above the lamp body 5. The above lamp was fixed to a 1.2 m mini-pole and grounded through this pole. A voltage of about 1000 KV was applied using an impulse voltage generator. Electrical energy is approximately 100KJ, earth resistance is 10
It was set to be less than K ohm. The experimental results show that in the case of conventional equipment,
There was no problem if lightning struck the base of the lamp, but if lightning struck from above the tip or from above the side, the lamp would be struck by lightning. In the case of the device of the present invention, lightning strikes were generated by positioning the discharge electrode at the same position as in the conventional device or in any direction. The results show that no matter where the discharge electrode is placed, lightning does not strike the lamp body, confirming a sufficient lightning protection effect.

In addition to light fixtures, the structure may be a building, an outdoor advertising tower, or any other arbitrary structure, and is effective when these structures are horizontally long.
