How many types of street lights can be divided into

1. According to the height of street lights: high pole street lights, road lights, courtyard lights;
2. According to the material of street lamp pole: steel street lamp and stainless steel street lamp;
3. According to the street light source: sodium lamp street lamp, LED street lamp, energy-saving street lamp.
4. Divided by shape: landscape lights, single-arm street lights, double-arm street lights.

5. According to the power supply mode: city circuit lights and solar street lights, wind-solar complementary street lights. Street lights involve lighting technology and are suitable for street lights. The purpose is to design a high-efficiency electronic energy-saving street lamp with long life, low power consumption, high power factor and low current harmonic content. The high-efficiency electronic energy-saving street lamp includes the power grid high-voltage discharge branch R1, C1, rectifier bridge D1-D4, power factor correction branch C2, D5, D6, high and intermediate frequency glitch filter branch L1, L3, and high-frequency oscillation circuit connected in sequence BG1-BG2, start branch L2, C7 and lamp T; compared with previous street lamps, it can save 80% of electricity; harmonic content THD<25%, extending lamp life up to 3-4 times.
Solar street light is a kind of street light that uses solar energy as an energy source. Because it is not affected by power supply, does not require trenching, does not consume conventional electricity, and can be installed on the spot as long as the sun is sufficient, it has attracted widespread attention. Because it does not pollute the environment, it is called a green product. Solar street lights can be used to illuminate urban parks, roads, and lawns, and can be used for areas with low population density, inconvenient transportation, underdeveloped economy, lack of conventional fuels, and difficult to use conventional energy to generate electricity, but solar energy resources are rich in areas to solve these areas People's home lighting problems.
Lamp height
1. The installation height of lamps and lanterns in the same street must be the same (the height of the luminous center to the ground). Small curved lights One meter light 5-6 meters ordinary street long arm lights and chandeliers 6.5-7.5 meters fast lane arc lights not less than 8 meters slow lane arc lights not less than 6.5 meters
2. The special lamp type is installed according to the design requirements, and the height of the lamp is equal to the width of the road to be illuminated. When lighting on one side only H≌L when lighting on both sides H≌L/2 where H: the installation height of the lamp
