LEDs are very energy efficient and low power consumption products
The LED power supply, also called the driving power supply, has only one function, providing a constant voltage and constant current power supply to the LED light beads. If the operating current of the LED exceeds the rated current or the voltage is unstable, the LED will quickly deteriorate and deteriorate. LEDs are very energy-saving products with low power consumption. Generally, the working voltage is only a few volts. A few of them are special-purpose light with a few tens of volts. The current used is also relatively low. Generally, it is calculated in milliamps. The wiring is directly connected to the household mains 220V, which is first passed through the driving power supply, stabilized and rectified before conducting to the LED light bead.
Separate isolated and non-isolated, non-isolated directly connected to LED light after voltage reduction, isolated power supply is the isolation of the input and output through the transformer, there is a process of electrical to magnetic and then to electricity, the safety is relatively relatively non-isolated The power supply is high and the cost is also more expensive. In addition, the functional guarantee of the LED driver power supply in short-circuit protection, surge protection, power-off protection, leakage protection, etc. is also the core factor affecting the final light price.
The price of led lights can be described as comprehensive coverage. When using led lights, you can choose according to your budget and the functionality of the lights.
