Driver power supply manufacturerPrinciples for judging the quality of LED driver power supply

1. The more output channels there are, the more complex it is. Currently, the interference between different channels is very expensive to resolve. If it is not resolved, the failure rate will be very high. In addition, the more output channels there are, the greater the total output current, and the current is the main cause of the problem of generating a lot of heat. The voltage itself does not have a direct effect on heat generation. Simply put, the heat is proportional to the square of the current, that is, the current increases to the original value. If it is 2 times, the heat generation increases to 4 times, the current can be increased to 3 times, and the heat generation increases to 9 times. In summary, the failure rate of single-channel or dual-channel signal output LED lamp power supply will be greatly improved. 2. The power supply manufacturer said that the power supply is the key to the internal control of the intelligent management system. Intelligent control has mature conditions and obvious effects in the application of LED street lights and LED tunnel lights. Intelligent technology control can realize stepless control of the lamp power in different time periods of enterprises according to the traffic density of Chinese roads, which not only meets the actual application development needs, but also achieves huge energy saving. 3. The drive power supply manufacturers say to abandon the traditional high power and ultra-high power, and choose small and medium-sized system power supplies with high stability. Because the greater the power, the greater the heat, the more compact the internal components, which is not conducive to cooling, and temperature is the main cause of power failure. In addition, small power supplies are relatively mature and have certain advantages in stability and cost. In fact, many high-power power supply solutions have not been verified by time and practice. They are all hastily launched projects and are all experimental products, so failures are endless. In contrast, due to the early development of small and medium-sized power supplies, the technical solutions are more mature. 4. Heat dissipation and protection are the main factors affecting the failure of power management systems. Not only the power supply itself will heat up, but the lamp will also heat up. How to reasonably distribute these two heat sources is a problem that lighting designers need to consider. To prevent excessive heat development, the main research focus is on forming an urban heat island effect and affecting the life of the working power supply. Using a separate power supply solution is a good choice. 5. Driving power supply manufacturer-feasibility of maintenance. The power outage problem cannot be completely avoided. A simple principle for maintenance is proposed. Only when replacing the power supply is as simple as replacing the light source of conventional lighting can users be satisfied. 6. Driver power supply manufacturer-protection performance. Environmental protection issues are also important. The infiltration of moisture may affect the short circuit of the working power supply. Dust on the outer shell will affect the heat dissipation of the working power supply. Exposure to sunlight can easily cause high temperature and aging of wires and other components. The failure rate of wiring plugs is very high, mostly caused by water leakage.
