2.5 The vertical lantern adopts waterproof hanging lamp head, and the lower lamp head is higher than 3m from the ground.
3 Building neon installations should meet the following requirements:
3.1 The neon tube is intact and there is no breakage;
3.2 The lamp tube is fixed by a special insulating bracket and is firm and reliable. After the lamp is fixed, the distance from the surface of the building or structure is not less than 20mm;
3.3 Neon-specific transformers adopt double-loop type, the length of the supplied lamps is not more than the allowable load length, and there are rain-proof measures for open-air installation;
3.4
The connecting line between the secondary wire and the lamp of the neon-specific transformer is a high-voltage insulated wire with a rated voltage greater than 15KV. The distance between the secondary wire and the surface of the building or structure is not less than 20 mm.
4 Installation of aviation obstacle sign lights should meet the following requirements:
4.1 The luminaire is installed at the highest part of the building or structure. When the plane area of ​​the highest part is large or is a group of buildings, in addition to being installed at the highest end, lamps are respectively installed at the tops of the outer corners thereof;
4.2 When the luminaire is installed on the top of the chimney, it is installed at a position 1.5 to 3 m below the chimney and arranged horizontally in a regular triangle;
4.3 The selection of the luminaire is determined according to the installation height; the low light intensity (used when installed below 60m from the ground) is red light, and its effective light is stronger than 1600cd.
