Reason 1: The cost of installing street lights on expressways is very high, and the installation distance of street lights is generally 30 meters to 40 meters. If the 50 meter street light is regarded as hundreds of kilometers on any expressway in China, the street light will be installed. major Solar street lamp The cost is very high. The second reason is that the expressway has a high safety factor. The expressway is a closed road connecting the city and the city. In the absence of pedestrians and non motorized vehicles, urban street lights are designed for the safety and convenience of non motorized vehicles and pedestrians. Third, automobile headlights and road reflective signs are sufficient to meet the lighting needs. Zhengzhou major Solar street lamp Discontinuous and uneven. For drivers of high-speed vehicles, this kind of light dark alternation will cause visual illusion, which is very dangerous.

There are many types of LED street lights, which can be classified according to the following categories. 1 major Solar street lamp Height of street lights: high pole street lights, medium pole lights, street lights, garden lights, lawn lights; 2, according to major Solar street lamp Material of lamp pole: hot-dip galvanized railway lamp, steel street lamp and stainless steel street lamp; 3. Divided by shape: Chinese lamp, antique lamp, landscape lamp, single arm street lamp, double arm street lamp. 4. According to the power supply mode: urban circuit light, solar street light, wind solar complementary street light.

1. Strong anti-static capability: LED with strong anti-static capability has a long service life. 2. Brightness: The price of LED varies with its brightness. 3. Wavelength: LEDs with the same wavelength and color are expensive. 4. Luminescence viewpoint: LEDs for different purposes have different luminescence viewpoints. 5. LED chip: major Solar street lamp The illuminant of is a chip, and the price of different chips varies greatly. 7. Colloid: Generally, the colloid of LED is epoxy resin. LEDs with UV resistance and flame retardancy are more expensive. 8. Chip size: the chip size is represented by the side length. Big chip major Solar street lamp Its quality is better than that of small chips. The price is proportional to the chip size. 9. Radiator: The radiator can see the appearance of the lamp. Temperature will affect the life of LED lamp beads. Counting plays a vital role. 10. Power supply: According to the plan requirements of different manufacturers, it can be divided into two types: constant current power supply and constant voltage power supply.

Using the integrated technology of LED electro-optic source, according to major Solar street lamp The characteristics of semiconductor luminescence, ingenious circuit design and unique lighting geometric appearance, major Solar street lamp It can save more than 80% of electricity, realizing effective energy saving. The ultra long service life is up to 50000 hours, which can be used well in various special environments (such as low temperature and high temperature conditions). It solves the problems of low power and insufficient brightness of semiconductor electric light source in the lighting field, and shows excellent high brightness characteristics. There is no need for ballast, no starting difficulty, complete overcurrent, overvoltage, short circuit, temperature, surge protection, and its lighting optical performance is brighter and more complete than 75W/400W/1000W metal halide lamp.

1. Lamp holder: it needs to be sealed through the lamp holder. major Solar street lamp The waterproof treatment of lamp cap can ensure the service life of street lamp. Therefore, the selection of street lamp housing is very important. 2. Controller: when selecting, pay attention to whether the style is waterproof. When installing the controller, it is usually placed in the road to better avoid wind and sun exposure. 3. Battery: it needs to have certain waterproof performance. In order to install the battery, please bury the battery about 40cm underground to avoid flooding. After that, test major Solar street lamp Head to check whether the street lamp lights up normally. If it is opened, it can be used normally; otherwise, it needs to be replaced. Light poles need to be hot-dip galvanized to ensure smooth surface, no color difference, no pinholes, and no skin peeling after use.

(1) High light efficiency: the spectrum is almost all concentrated on the visible light frequency, and the efficiency can reach 80% - 90%. (2) High light quality: because there is no ultraviolet and infrared ray in the spectrum, there is no heat and radiation. This is a typical green light source. (3) Long life: the standard life is 40000 hours when the luminous flux decays to 70%. major Solar street lamp It can be used for 8 years under normal conditions. (4) Reliable and durable: there is no tungsten wire, glass and other easily damaged parts, the abnormal scrap rate is very small, and the maintenance cost is very low. (5) Flexible application: small size, flat packaging, easy to develop into light, thin, short products, can be made into various forms of dot, line, surface special products. (6) Green environmental protection: waste can be recycled without pollution, major Solar street lamp And unlike high-pressure mercury lamps, they contain mercury. (7) Very short response time: energy-saving ceiling lamp suitable for frequent switching and high-frequency operation.
