Description

A convenient LED drive device for installation

technical field

The utility model relates to the technical field of LED driving, in particular to a conveniently installed LED driving device.

Background technique

In the prior art, LED lighting basically adopts a constant current driving mode. In order to better utilize the advantages of energy saving of LED lighting, it is the general trend to add a dimming function to the LED driver. Generally, there are three dimming methods for LED drivers: thyristor dimming, analog dimming, and PWM dimming. Each dimming method has its advantages and limitations. In terms of eye recognition ability, it works at a frequency high enough to change the average value of the output current by setting the period and duty cycle. The output current has only two states: the maximum rated operating current and zero current. Analog dimming is achieved by changing the output current. Amplitude to achieve dimming function, thyristor dimming is to achieve dimming function by adjusting the output power of the power supply, PWM dimming can ensure that the color temperature of the LED is constant, the efficiency of the driver is high, and it can be accurately controlled, but its The disadvantage is that the MCU controller is required, the cost is high, the analog dimming is simpler and easier to implement than the PWM dimming circuit, but it will change the color temperature of the LED, and at the same time, the efficiency is low, the output current accuracy is not easy to adjust, and the dimming range is limited. Just using the existing thyristor dimmer, by changing the conduction angle of the thyristor and adjusting the output power to achieve dimming, the advantage is that the original fluorescent lamp dimming equipment does not need to be changed, but the disadvantage is more serious: it will Seriously reduce the efficiency and power factor of the driver, and also cause the LED to flicker.
