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 Mining lamp 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 Mining lamp 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. When you buy back the LED ceiling lamp, please do not install it. Please read the label of the bulb carefully and read the installation manual, and then install and use the LED ceiling lamp according to the instructions, otherwise it may be dangerous. 2. Please be careful not to change it during cleaning and maintenance major Mining lamp Do not replace the parts of LED ceiling lamp at will. After cleaning and maintenance, install the bulb as it is, and do not omit or install the bulb components incorrectly; 3. Maintenance is required during use major Mining lamp To extend its service life. Wipe with dry cloth frequently, and pay attention to prevent moisture intrusion to avoid rust or long-term leakage and short circuit; Wipe as much as possible to avoid affecting light penetration.

1. The installation height of LED energy-saving mining lamp is determined according to the environment, because the environment will change the reflection efficiency of the lamp. Generally, the height of LED energy-saving ceiling lamp should be more than 5 meters, and the wires should not be close to the enclosure of the ceiling. If necessary, install it. If it is less than 3m, protective measures shall be taken to prevent the vehicle from contacting it. two major Mining lamp Waterproof and low-temperature treatment. Select the ceiling lamp with waterproof function and waterproof transformer. The chip package of the bulb is wrapped with high temperature insulating material, which can not only be waterproof, but also prevent the bulb from being damaged at low temperature under harsh conditions. three major Mining lamp engineering Use flat hard copper wire to connect the main line of LED energy-saving mining lamp wiring to the lamp, install one in five rings, and connect them evenly to three phase lines according to the load balance requirements.

one major Mining lamp The charging circuit adopts a dual MOS series control circuit, which can reduce the voltage loss of the circuit by nearly half compared with the use of diodes. The use of PWM energy-saving control greatly increases the power consumption. 2. The load mode adopts pure light control. When the light is dark, the light sensor system will automatically light up. 3. Scientific battery management method. When over discharge occurs, the battery voltage will promote charging. After maintenance and compensation, it can be used normally. Direct charging and floating charging are used to connect rechargeable batteries. 4. All restrictions of all industrial chips and closed components can operate normally in cold, high temperature and humid environments. At the same time, major Mining lamp The use of crystal oscillator time control can make the time control more accurate.

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 Mining 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. Yantai major Mining 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 Mining 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 Mining lamp There are many reasons for dead lights. Dead light may appear in every link from packaging, application to use.
