There are two types of LED drive batteries: 1. Constant voltage drive.
According to different load conditions, the driving battery outputs a constant voltage to light the LED lamp. 2. Constant current drive.
According to different load conditions, the driving battery outputs a constant current to light the LED lamp.
High efficiency of led driving battery: LED is an energy-saving product, and the efficiency of driving battery is high.
It is especially important for the structure in which the battery is installed in the lamp.
Because the luminous efficiency of LED decreases with the increase of LED temperature, the heat dissipation of LED is very important.
The efficiency of the battery is high, the loss power of the led drive battery is small, and the calorific value in the lamp is small, thus reducing the temperature rise of the lamp. It is beneficial to delay the light decay of LED.
Led drive battery high power reason: The Power reason is the load requirement of the power grid.
It is usually for electrical appliances below 70 watts, with no mandatory indicators.
Although the low power of a single electrical appliance with low power has little effect on the power grid, it will cause serious pollution to the power grid if everyone lights up at night and the similar load is too concentrated.
For 30 watts ~ 40 w led drive battery, I believe that in the near future, may have a certain index requirements for power reasons.
