1. Different in nature
1. The nature of the switching power supply: a high-frequency electric energy conversion device.
2. The nature of the driving power: a power converter that converts the power supply into a specific voltage and current to drive the LED to emit light.
Two, the characteristics are different
1. Features of switching power supply:
(1) Small size and light weight: Because there is no power frequency transformer, the volume and weight are only 20-30% of the linear power supply.
(2) Low power consumption and high efficiency: The power transistor works in the on-off state, so the transistor has low power consumption and high conversion efficiency, generally 60-70%, while the linear power supply is only 30-40%.
2. Characteristics of driving power supply:
(1) High reliability It is especially like the driving power supply of LED street lights, installed at high altitude, with a waterproof aluminum housing driving power supply. If the quality is good and not easy to damage, reduce the number of repairs.
(2) High-efficiency LED is an energy-saving product, and the efficiency of the driving power supply should be high. It is particularly important for the power supply structure installed on the lamp. Since the luminous efficiency of the LED decreases as the temperature of the LED increases, the heat dissipation of the LED is very important. The power supply has high efficiency, low power consumption, low heat generated in the lamp, and also reduces the temperature rise of the lamp. It is beneficial to delay the light attenuation of the LED.
Switching power supplies have two main operating modes: forward conversion and boost conversion. Although the layout of each part is different, the working process is different, and each has its own advantages in specific applications.
The switching power supply uses electronic switching devices (such as transistors, field effect transistors, thyristors, etc.). The electronic switching devices are continuously "on" and "off" through the control circuit, so that the electronic switching devices can pulse modulate the input voltage to achieve DC/AC, DC/DC voltage conversion and output voltage can be automatically adjusted and stabilized.
