According to the rules of grid electricity and the characteristics of the LED driver requirements, selection and design of LED drive power to take into account the following: 1. High reliability, especially as the drive power of the LED lights installed at high altitude, inconvenient repairs and maintenance spend. Two. High-efficiency LED energy-saving products, the higher the efficiency of the drive power. LED driver power supply for power installation
Lighting within the structure, is particularly important. LED luminous efficiency of LED temperature decreases, so the LED heat dissipation is very important. High efficiency power supply, the loss power, heat lamps, and reduces the temperature rise of the lamps. Beneficial to delay the LED light failure.
3. The high power factor power factor power grid load requirements. Appliances generally less than 70 watts, there is no mandatory targets. Power is not a single electrical power factor on the grid has little effect, but at night we light a lamp, focus too much on similar load, the grid will produce a more serious pollution. 30 watts to 40 watts of LED drive power, said that in the near future, will power factors may have certain specifications.
4. Driven approach is now common, there are two: one is a constant voltage source for the constant current source, each constant current source separately to each LED power supply. In this way, the combination of flexible, all the way to the LED fault, does not affect the other LED's work, but the cost will be slightly higher. Another is a direct constant current power supply, LED in series or parallel operation. Its advantage is low cost, but the flexibility is poor, but also to solve a LED fault, does not affect other LED running. These two forms co-exist within a certain period of time. Multi-channel constant-current output power supply, in terms of cost and performance. May be a future direction of the mainstream.
5 Surge Protection LED Surge capacity is relatively poor, especially the anti-reverse voltage capability. Is also important to strengthen this protection. Some LED lights installed in the outdoors, such as LED street lights. Kai rejection grid load and the induction of lightning from the grid system will invade a variety of surge, some surge can cause damage to the LED. LED driver manufacturer have to inhibit the intrusion of the surge, the ability to protect the LED is not damaged.
6. Protection function power in addition to conventional protection functions, the best increase in the constant current output LED temperature negative feedback to prevent the LED temperature is too high.
7. Protection aspects of lighting outside the installation type, the power structure to be waterproof, moisture, shells and light fastness.
8. The drive power of life and the life of the LED adapter. Waterproof led driver can work in out door enviroment.
9. To comply with the requirements of safety and electromagnetic compatibility. With the increasingly widespread application of LED, the LED drive power performance will be more and more suited to the requirements of the LED....
