(Summary description) Road lighting is an indispensable part of urban construction. Setting lighting on both sides of the road not only illuminates pedestrians and vehicles, but also reduces the fatigue of drivers and ensures road traffic safety. In other countries, some public lighting in cities is also included in road lighting. The lighting of streets, highways, bridges and other places belongs to road lighting. Road lighting should first meet the requirements of car drivers to accurately identify various conditions on the road when driving at night, to respond to obstacles in time, to avoid traffic accidents, and to reduce drivers' visual fatigue. Since there is a certain minimum brightness difference between the surface of the object and the road surface, the object can be perceived, so the average road surface brightness is an important indicator. According to the test, the average road brightness value should be 1.5~2.0 candela per square meter. It is divided into the brightness uniformity of the whole road surface and the longitudinal brightness uniformity. The former represents the brightness uniformity that affects the driver's comfort; the latter represents the brightness uniformity that affects the visibility of obstacles. According to the specific road and environment, the lighting device and installation method should be selected reasonably to achieve the purpose of good lighting effect and energy saving. Lighting fixtures should have a reasonable light distribution so that they can be effectively directed at the illuminated object, limit glare, and protect the light source. In the past, incandescent lamps were mainly used as lighting sources, and high-efficiency gas discharge lamps are now used, such as fluorescent high-pressure mercury lamps with improved light color, high and low pressure sodium lamps and metal halide lamps. Installation methods include cantilever type, suspension cable type and multi-lamp combination type.

What are the characteristics of LED roadway lights? Do you know the installation method and precautions? Take a look!

　　As people's requirements for lamps are getting higher and higher, a new type of lamps called LED lamps are favored by people. LED is a kind of light-emitting diode. As a light source for illuminants, it has high light efficiency and long life. To achieve multi-purpose lighting, and softened, it will not cause dazzling or other uncomfortable reactions, so many public areas will use this kind of light, such as LED roadway lights, because there are many people on the road, so it is necessary to To install soft lamps that will not hurt the eyes, what are the characteristics of LED road lights? Do you know its installation methods and precautions? Let's follow the editor to learn about it. 　　 Features of LED roadway lights: 1. The color purity of LED roadway lamps is high; at present, LED products cover almost the entire visible spectrum range, and the color purity is high. 2. LED roadway lamps have a long life. The actual life of LED is more than 50,000 hours, which is several times or even dozens of times that of general light sources. 3. The light source of LED roadway lamps does not contain mercury, and the light beam does not contain ultraviolet rays. 4. It is solid luminescence, good shock resistance, firm and reliable. 5. It also has the characteristics of energy saving, economical and maintenance-free. 6. LED has strong luminous directionality, high luminous flux utilization rate, and small size, which is easy to design and control light intensity distribution of LED lamps. 7. LED roadway lamps can be powered by DC low voltage, which is safe and reliable. 8. The LED is not limited by the start-up temperature, it can be started temporarily, usually a few ms, and can temporarily achieve full luminous flux output. 　 Installation method and precautions of LED roadway lights: 1. Installation method: 1. First, determine the installation position and method of the lamps according to the actual needs of the work site, and then prepare the corresponding length of Φ8~Φ14 mm three-core cables according to the distance from the lamps to the power contacts. 2. Open the set screw on the side of the upper cover of the lamp, then loosen the compression nut of the cable inlet of the lamp, open the upper cover, and lead the power cables through the compression nut to the internal terminal, and connect according to the method shown in the figure. Fix it, and then tighten the cable compression nut and the upper cover of the lamp. 3. The LED roadway lights are enclosure-free. If the lamps themselves are not bright, generally communicate with the manufacturer for direct replacement or return to the factory for maintenance. 2. Notes: 1. The power supply must be cut off before dismantling the lamp. 2. It is strictly forbidden to open it with electricity. 3. During use, the surface of the lamp has a certain temperature rise, which is a normal phenomenon; the center of the transparent part has a high temperature and should not be touched. 4. When installing lamps, the lamps should be safely grounded nearby. The above are the characteristics of LED roadway lights, as well as its installation methods and precautions. Relevant staff must pay attention to the problems during installation to ensure their personal safety.
