At present, the LED lights all use DC driver, so in the utility and LED light, if the LED light want to work in a normal state, it is a must to add a power adapter which also called LED driver power supply. Its function is to exchange the utility converted into appropriate DC current suitable for the LED. According to the power grid electricity rules and special requirements of LED driver, there are a few tips for you to choose and buy the LED constant current driver.
Tips to Choose LED Driver
1. The high reliability. Special LED light driver power supply, it is installed into the air, maintenance is not convenient, and the cost of maintenance is very huge. 2. High efficiency. LED is a new kind of energy-saving products, so the driver efficiency should be high. It is particularly important that the power installed in the light. Because of the LED luminous efficiency declines with the rise of LED temperature, so LED cooling is very important. If the power of the high efficiency is less than the power loss is small too, and the heat is small in lamps, this also reduced the rise of temperature of the lamps. 3. High power factor. Power factor is the requirement of electric load. Generally, appliances below70 watts, it has no mandatory index. Although a single used electric power of the small power, its influence of a low power grid is not big, but if all people light up the lights at night, at this time, the same load focused too much, and this will generate a serious pollution to power generates.
Since the LED lights are a kind of sensitive semiconductor devices, and they also have characteristics of negative temperature, thus in the application process we have to do the steady working state and protection for them, so the creation of the concept driver appeared. And at the same time, many led driver manufacturer have a long-term vision to research and develop all kinds of LED driver to meet the market demands. The requirements that LED driver to the power supply device is near demanding, LED is unlike the regular incandescent light bulbs, can be directly connected to the 220 V AC utility. LED is 2~3v low voltage driver, the relatively complex transform circuit is a must for the designer to do that. Different LED lights must be equipped with different power adapters. The international market customer have a very high requirements to the foreign customers' LED drive power efficiency conversion, effective power, constant current accuracy, power supply and service life. To design a good power supply must be integrated to consider these factors, for the function of the power supply is just as important as the heart of human beings.
