During use, the bulb will be hit by wind and rain, which may cause its angle deviation, thus affecting the lighting effect. If any deviation is found, it must be adjusted in time. Check the bulb surface regularly. If on major Floodlight Cracks found on the surface glass of the bulb may cause rainwater to enter the bulb, which will seriously affect the use effect and service life of the bulb. The bulb should be removed immediately and sent to the original factory for repair. Avoid all kinds of serious accidents, such as leakage. Clean the lamp regularly to maintain its brightness. Turn off the lamp before cleaning it major Floodlight The power supply of the lamp shall be cleaned with a dry cloth or dry cloth to prevent the lamp from being damp, let alone with chemical or corrosive substances. Otherwise, the bulb will be corroded, which may cause accidents.

If there is a problem with the solar street lamp in the countryside, first check whether the photocell is correctly connected, whether the wiring position is in poor contact, and then check whether the battery connection is correct and whether the battery voltage is normal. If the battery is excessively discharged, a fault will occur and it will automatically recover after being fully charged. Among them, major Floodlight The stability of the controller is very important for the service life of rural solar street lights, because the role of the solar controller is to control the use major Floodlight The battery board charges and discharges the battery. When choosing a solar cell, you must choose a high stability battery to ensure the service life of the battery, because the quality of the battery will also directly affect the service life of the street lamp. It can extend the service life of the whole rural solar street lamp.

The life of LED mining lamp depends largely on the level of heat dissipation, and the main way to improve the level of heat dissipation is to transfer the excess heat generated by the chip through the radiator and radiator. At the same time, major Floodlight The main parameters related to LED heat dissipation are thermal resistance, junction temperature, temperature rise, etc. Thermal resistance is the quotient obtained by dividing the difference between the effective temperature of the equipment and the temperature of the external designated reference point by the steady-state power consumption in the equipment. It is an important parameter indicating the degree of heat dissipation of equipment. Junction temperature refers to the temperature of the semiconductor junction of the main heating part in the LED device. It reflects major Floodlight Temperature value that can be withstood under working conditions. Temperature rise refers to the temperature rise of the enclosure environment. It refers to the difference between the temperature of LED equipment shell and the ambient temperature. This is a temperature value that can be directly measured, which can directly reflect the heat dissipation degree around LED devices.

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 Floodlight 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 Floodlight 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. Energy saving economy. First, each solar street lamp is a relatively independent system. In the process of installation and construction, there is no need to lay cables or dig roads, thus saving a lot of manpower, material resources and installation costs; In addition, it also consumes electricity, and ordinary street lights are on all day. The lamp lasts about 6 hours, consumes about 2 kWh, and the annual electricity charge is more than 300 yuan. According to 300 street lights in the urban area, the annual cost is nearly 100000 yuan. Can be saved major Floodlight 。 2. Energy conservation and environmental protection. qinghuangdao major Floodlight It is mainly composed of four departments: photovoltaic module, light-emitting diode, solar cell and controller. Photovoltaic modules absorb light in the daytime, convert solar energy into electric energy, store it in solar cells, and release illumination when it turns dark at night.
