A, there are many types of street lamp type street light classification, according to the light source cocoa into the LED street lamp, electrodeless lamp lights, energy-saving lamps, street lamp, high-pressure sodium lamp, metal halide lamp, street lamp, etc. , according to the occasion can be divided into ordinary street light, high street lamp, garden lamp, landscape lamp, etc. , other
there are many kinds of a type street light, street light. They can be divided into led street lamp, electrodeless lamp, energy-saving lamps, street lamp, high-pressure sodium lamp, metal halide lamp, street lamp, etc. According to the different light source, can be divided into ordinary street light, high lamp, garden lamp, landscape lamp, etc. Other lamps is also combined arms can be divided into single arm street light, street light, street light, solar street lamp, etc. Second, the street lamp light lamps light including led lamp, electrodeless lamp, the common energy-saving lamps, high pressure sodium lamp, metal halide lamp and so on. What kind of street lamp light source is better? Metal halide lamp and ordinary energy-saving lamps of low cost, long service life, convenient maintenance, but this kind of street lamp light source power consumption is higher, is not recommended. High pressure sodium lamp, although has the good through fog is one of the commonly used before street lamp light source, but its service life, energy conservation and relatively poor, so choose high pressure sodium lamp is not recommended as a street lamp light source. Electrodeless lamp is also a kind of energy-saving lamps, theory of life is long, but the cost is high, it is not easy to maintain. Don't recommend choose such a light source. Street light emitting diode light source is the most widely used light source in recent years, with high efficiency, energy saving, environmental protection, long service life, convenient maintenance and low price, etc. In addition, many countries and regions are vigorously promoting leds, and it is recommended to use led light source. LED street lamp is the first selection of road lighting. Third, street lamp spacing street lamp spacing is street lamp spacing, it is composed of street lamp, street lamp lighting power factors such as height, width of the street. Street lamp spacing is generally 3 lamp height. 8 - 4 times. Street lamp of the longitudinal spacing generally is 30 m and 50 m, when have a pole or other pole spacing is 40 m ~ 50 m. Combine the power supply and lighting rod as far as possible, to save investment. If you use the underground cable power supply, spacing should be smaller, this contributes to the uniformity of illumination. Usually for 30 - spacing 40 meters. Four, street lamp height (street lamp Light pole height) General is 6 m, 8 m, 10 meters, 12 meters, 15 meters, etc. Street lamp height of concrete used should be based on the width of the road. In the case of a single light distribution, street lamp height is in line with the road width and height is less than the road or street lamp width of 1 m. Ordinary led lamp power and the relationship between the lamp height is commonly: 30 - 60 w street light height is less than 6 m, 60 100 w street light height less than 8 m, 100 ~ 150 w street light height less than 10 m.
