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.

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.

major Mining lamp Coordination of color temperature and illuminance. The color temperature of light source is the color expression of light, major Mining lamp The psychological effects of light color on people include cooling and heating effects and other expansion effects. The cooling and warming effect is based on the blue-green and red orange as the two extremes of "cold color" and "warm color". It is generally believed that red has a warm feeling, while cyan has a cold and muddy feeling. The color temperature should be selected to achieve the desired lighting effect as to what kind of nightscape environment atmosphere needs to be created. The influence of color temperature on people is not only the feeling of cold and warm, but also the environmental illuminance. At low illumination levels, warm light with low color temperature is more acceptable, while at higher illumination levels, cool light with higher color temperature is more popular.

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.
