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 City circuit 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 City circuit 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.

1. Quality assurance, green and environmental protection, our LED lamp has a long life, low light attenuation and high brightness. They are the first choice for energy-saving transformation of factories. 2. Energy saving. The service life of Danohangpu LED products can reach 50000 hours, and the energy-saving effect is 40% - 60% of that of ordinary lamps, greatly reducing the power consumption. 3. Professional major City circuit lamp Plan and plan. Make a reasonable lighting configuration plan according to the width of the road and the lighting time of the area, so that you will not waste money and reasonably configure the light source. 4. Professional technical guidance and after-sales service, professional technical team major City circuit lamp We provide on-site technical guidance and problem solving for the installation and transformation of. Perfect after-sales service is our intimate guarantee for users. 5. From the manufacturer to the manufacturer, shorten the intermediate link, and directly solve the problem that dealers do not understand the technology and the price is slightly higher from the manufacturer's plan - product customization - product inspection - product delivery - manufacturer acceptance, and one-stop service.

(1) There are potential safety hazards in municipal lighting: due to the construction quality, garden engineering transformation, aging materials, abnormal power supply, water and electricity pipeline conflict, many potential safety hazards have been brought. (2) Solar street lamps are energy-saving and environment-friendly new energy power generation products. There is no electricity bill. High electricity charge for mains lighting: major City circuit lamp Our jobs have fixed and high electricity bills. Solar lighting is free of electricity charge: solar road lighting is a one-time investment without any maintenance costs, the investment cost can be recovered within three years, and has long-term benefits. （3） major City circuit lamp The installation of the solar street lamp is very simple: when installing the solar street lamp, you don't need to lay complex lines, just make a cement base and fix it with stainless steel screws. The installation of municipal lighting fixtures is very complicated: there are complex operating procedures in the municipal lighting project.

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 City circuit 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. Jilin major City circuit lamp Discontinuous and uneven. For drivers of high-speed vehicles, this kind of light dark alternation will cause visual illusion, which is very dangerous.
