1. Shandong solar street lights will not go out suddenly: solar street lights use solar energy to absorb sunlight to charge batteries. When the weather is bad, the battery will provide power for the street lamp lighting, so the lamp will not be turned off suddenly. 2. Quality of LED light source: major City circuit lamp LED lamp cap is generally used as the light source of. Because LED lamp cap has many advantages, its lighting life is long, and it will not emit too much heat when used, which greatly extends the service life of the light source. 3. It can also be used normally in continuous rainy days: major City circuit lamp Solar energy is used to generate electricity, so they can usually be used for lighting on days without sunshine. Solar street lamp manufacturers will also consider these issues when designing solar street lamps, and then through communication with customers, according to the local rainy weather conditions of customers, they will configure appropriate street lamp accessories to solve most local problems.

The working voltage of a single bulb for LED tunnel lighting is very low, about 3V, so the power consumption of a low-voltage working environment is half of the power required for the same strong light. The tunnel lamp has a long service life and does not need regular maintenance and inspection. After a period of use, the traditional major City circuit lamp The brightness of the tunnel lamp will be greatly reduced, but its attenuation is only 20% of that of the tunnel lamp. Moreover, the tunnel lamp is small in size and can be made into various shapes to adapt to various environments. The shell of the tunnel lamp is of integrated design, which is durable and not easy to be damaged. Each light source inside can be installed and removed separately, which is very convenient in the future maintenance process, and the overall design can ensure good heat dissipation effect. The heat dissipation rack inside the shell, the airflow and the heat emitted by the full contact with the air, effectively reduce the major City circuit lamp And prolongs the service life of the tunnel lamp.

1: Environment friendly lamp. LED products do not contain lead and other harmful substances, and the shell can also be recycled, which is harmless to the environment. 2: Fever is low. No UV, 3: no noise. LED light will not produce noise, so it is a good choice for occasions where quasi dense electronic instruments are used. 4: Protect eyes. major City circuit lamp LED constant current operation can effectively reduce LED light attenuation, start quickly, no flicker and protect eyes. 5: There is no trouble of mosquitoes, no harmful substances such as mercury, and less heat generated. 6: Wide voltage range. LED lights can be lit within a certain voltage range. 7: Power saving and long service life. It can be used for a long time without replacement, which reduces the labor cost. 8: Firm and reliable. major City circuit lamp It uses epoxy resin instead of traditional glass. 9: The appearance and size of multi-functional LED lamps are the same as those of traditional fluorescent lamps, which can replace traditional fluorescent lamps. 10: Rich color makes full use of the rich color of LED to make a variety of light emitting colors.

(1) Recommended installation height of 50W LED energy-saving mining lamp: 3-5 meters; Installation distance: 5-8m. (2) Recommended installation height of 100W LED energy-saving mining lamp: 6-8m; Installation distance: 8-10 m. (3) 120W LED energy-saving mining lamp Recommended installation height: 8-10m; Installation distance: 8-10 m. （4）150W major City circuit lamp Recommended installation height: 10-15m; Installation distance: 8-12m. （5） major City circuit lamp 200W Recommended installation height: 10-15m; Installation distance: 10-15m. (6) LED energy-saving mining lamp 300W recommended installation height: 15-20m; Installation distance: 20-25m. (7) Recommended installation height of 450W LED energy-saving mining lamp: 15-20m; Installation distance: 25-30m

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. Xiangyang 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.

1、 Disconnection. For "dead light", we should first determine major City circuit lamp Is it short circuit or open circuit. 2、 The adhesive layer is peeled off. For some LED energy-saving project lights with vertical chips, the common reasons for dead lights are the peeling off of the bottom of the chip bonding layer and the peeling off of the bracket coating. 3、 The welding spot is burnt. In some cases, the dead light of the bulb may not be caused by the bulb itself, but also by the power supply used. 4、 Chip corrosion. The previous energy-saving floodlights and energy-saving floodlights are open circuit. The following is the condition of short circuit dead light. major City circuit lamp There are many reasons for dead lights. Dead light may appear in every link from packaging, application to use.
