Driver power supply manufacturer of driver power supply function
 

2. The high efficiency of the driving power supply manufacturer is an energy-saving product with high driving energy efficiency. It is especially important for the structure where the power supply is installed on the lamp. Since the luminous efficiency will decrease with the increase of temperature, the heat dissipation is very important. The power supply has high efficiency, consumes less energy, and the heat dissipated in the lamp is small, which reduces the temperature rise of the lamp. This is conducive to delaying the light decay. 3. High energy factor The energy factor is the load requirement of the power grid. Generally, there is no mandatory indication for electrical appliances below 70 watts. Although the energy factor of a single small energy appliance is low and has little impact on the power grid, when everyone turns on the lights at night, the same load is too concentrated, which will cause more serious pollution to the power grid. For 30W~40W drive power supplies, it is said that in the near future, there may be certain index requirements for energy factors. 4. There are two driving modes for the power supply manufacturer: one is to use a constant voltage source as multiple constant current sources, and each constant current source is for each power supply. This combination is flexible, and one failure does not affect the work of other sources, but the cost will be slightly higher. The other is a DC constant current power supply, which runs in series or in parallel. Its advantage is low cost, but poor flexibility, and it also solves the problem that one failure will affect the operation of other sources. These two forms coexisted for a while. Multi-channel constant current output power supply is cost-effective. This may be the mainstream direction. 5. The surge protection capability of lightning protection is relatively poor, especially the anti-reverse pressure capability. It is also important to strengthen this preservation. Some lights are installed outdoors, such as street lights. Due to grid load throwing and lightning induction, various surges can enter from the grid system, some of which can cause damage. Therefore, the driving power supply should have the ability to suppress surge intrusion and preserve it from being damaged.

6. In addition to the normal storage function of the power supply, the storage function also adds temperature negative feedback in the constant current output to prevent the temperature from being too high.

7. When the lamp is installed and stored outside, the power structure must be waterproof and moisture-proof, and the shell must be sun-resistant.

8. The life cycle of the drive power supply should match the life cycle of the drive power supply.

9. The drive power supply manufacturer meets safety regulations and electromagnetic compatibility requirements.

As the application becomes more and more extensive, the performance of the driver power supply of the driver power supply manufacturer will become more and more suitable for the requirements.
