What is the structural composition of the led flat lamp? What are the categories?
 
1. Look at the driving power supply used by the lighting. The service life of the power supply is much shorter than that of other parts of the lighting. The life of the power supply affects the overall life of the lighting. The theoretical life of the lamp bead is 50,000-100,000 hours. The service life is between 0.2 and 30,000 hours. The design and material selection of the power supply will determine the service life of the power supply. The power drive of aluminum alloy is better than that of engineering plastic. First, it has better heat dissipation, and second, it can effectively protect the parts inside from being crushed and loose during transportation and use, and reduce the failure rate of power drive.
 
2. Look at the light effect: the same lamp bead power, the higher the light effect, the higher the brightness, the same lighting brightness, the smaller the power consumption, the more energy-saving.
 
3. Look at the power supply efficiency. The higher the power supply efficiency, the better. The higher the power consumption, the smaller the power consumption and the greater the output power.
