  Neon lights are actually neon lights, which are mainly used as artistic and decorative light sources. The neon tubes in the neon gun-type high-voltage and low-voltage test pencils used in daily use are made of simple neon tubes.

  Neon lights mainly use glass tubes with a diameter of 11-20 mm and a length of 3-6 meters as the lamp tube. Both ends of the lamp tube are equipped with an electrode. After the glass tube is evacuated, it is filled with inert gases such as neon or xenon, helium, and argon. As a luminous medium. Most of the light emitted by neon lights is reddish orange. If the tube is filled with neon, helium, krypton, argon, xenon and other gases, or the glass tube is coated with various transparent pigments, the neon lights will emit a variety of bright brilliance.

  The voltage used by the neon lamp is 6000~15000 volts, and its voltage is proportional to the length and diameter of the tube, but the current consumption is very small, generally 18~30 mA, so the neon lamp is a high-voltage, weak-current electric light source , Should be powered by a holding transformer. At the same time, its power factor is very low (between 0.2 and 0.47), and it must be equipped with corresponding capacitors for compensation.

  The installation of neon lights should meet the following requirements:

  (1) Neon lights should be matched with corresponding transformers, and should not share the same circuit with other power sources.

  (2) The high-voltage wires of neon tubes should be high-voltage insulated wires, or bare copper wires covered with glass tubes; when the wires pass through the wall, they should be installed in double-layer glass sleeves, and the sleeves should be exposed 8~8 cm on the wall. ; The distance between high-voltage lines, between high-voltage lines and the laying surface shall not be less than 5 cm, and the distance between supports shall not be greater than the following values: 0.5 meters for horizontal laying; 0.75 meters for vertical laying.

  (3) The wire connections should be staggered, and the connection points should be covered with glass tubes with a length of not less than 100 mm.

  (4) The height of the neon chandelier from the ground shall not be less than 2.5 meters, and reliable protection shall be provided when the height is less than this height; the neon chandelier shall be hung with galvanized iron wire or copper wire.

  (5) The height of the neon tube from the ground shall not be less than 4 meters, and the height from the balcony, windows and doors, and overhead lines shall not be less than 1 meter.

  (6) The distance between the neon tube and flammable objects, other lines, water pipes, gas pipes, etc. should not be less than 300 mm; the clearance distance between the iron frame and pull wire of the outdoor neon light and the high-voltage overhead line should not be less than 2 meters.

  (7) When neon lights are installed in the window, the window door and the primary side switch of the transformer should have an interlocking device.
