LED Drivers: LXV40-012SW Application Field and Working Principle

LED Driver is an integral part of LED lighting system and plays very important role in the operation of LED light source. So we need to know more info about it, in this article, we will focus on the LED driver product named LXV40-012SW, discussing its application field and working principle.

LXV40-012SW Application Field

LXV40-012SW is a 12W constant current LED Driver, it has wide voltage range: 180-265V 50Hz, it has two output channels, each of which is capable of providing up to 6W of output power, its nominal output current is 500mA, LXV40-012SW is suitable for various LED lighting applications.For outdoor applications, LXV40-012SW can be used in landscape lighting, street lighting, garden lighting, etc., for indoor applications, it can be used for efficient lighting of shops, restaurant, offices, hotel, etc., for industrial applications, it can be used in LED light factory production line, warehouse lighting, etc. LXV40-012SW has high reliability and long life, it can work and survive in respectively -20°C〜+60°C and -20°C〜+50°C, so it is applicable for wide temperature range, making it suitable for both indoor and outdoor lighting applications.

LXV40-012SWWorking Principle

LXV40-012SW LED Driver is a lighting control device that uses Thyristor as a switch, and the speed of its switching is adjustable, so that it can control the output power and voltage of LED, making it possible to power the LED with a constant current.This LED Driver work on the principle of constant current, it can be used to drive power LED with forward voltage of 2.7 - 3.5V, when the AC input voltage of the LED Driver falls in the range of 180 - 265 V 50 Hz, the luminaire servo system will send a signal to control the switching on/off time of the Thyristor switch. The power output of the LED is converted to a constant current output, which is regulated by the switching time of the Thyristor switch, in this case, the LED can be driven with a constant current and there won\'t be visible flicker.

Conclusion

To sum up, LXV40-012SW is an LED Driver which has wide voltage range of 180-265V 50Hz and two output channels each of which can provide up to 6W of output power, it is suitable for various LED lighting applications, such as landscape lighting, LED light factory production line, warehouse lighting, street lighting, garden lighting, shops, restaurant, offices, hotel, etc.. And its working principle is based on the principle of constant current, its power output is regulated by the switching on/off time of the Thyristor switch, so it can provide constant current power to the LED and avoid flicker.
