UVLED solidified light sources (here contains UVLED facial light sources, UVLED wire light sources, UVLED dot light sources) The mode of adjustment of lighting power is PWM methods and simulation methods. This article discusses some concepts of these methods. Make UVLED periodic diversion and cut off. This method is called pulse width modulation (PWM). During the turnover, the current is the rated value. The percentage of the turnover time is called duty cycle (DC). The average current of the UVLED is equal to the product of the current and the duty ratio of the current to the duty ratio when the UVLED is turned on. In practical applications, according to the characteristics of UVLED ultraviolet light, the frequency of PWM is generally greater than 60Hz. Usually use digital chips for PWM modulation. UV curing devices such as UVLED light sources produced by Tianhui use a new generation of digital modulation chips. Reliable continuous work in a complex environment.

UV LED mosquito lamps are a game changer. Using advanced UV technology, they offer a chemical-free, energy-efficient, and super-effective solution to getting rid of mosquitoes. Unlike traditional repellents, they provide long-term benefits with minimal maintenance and no side effects.
As summer approaches, so does the pesky problem of mosquitoes. These tiny insects can ruin a peaceful outdoor evening, leaving us with itchy bites and disease risk. Fortunately, there's a solution in the form of UV LED mosquito traps. These devices use the power of ultraviolet light to attract mosquitoes and other flying insects better.
