Working voltage of LED light board
The working voltage of the LED light board is a matter of the design plan. It is related to stability, reliability, efficiency and safety factor, and has nothing to do with how wide the input voltage is; the input voltage range is suitable for the use area, and it works with LEDs. Regardless of voltage, the main purpose of step-up and step-down conversion is to make high PFC requirements. Of course, this is very suitable for the input voltage requirements of the model. The product has strong versatility and high PFC to meet high PFC requirements. As a product solution, the first thing to consider It is technical feasibility rather than cost. So in terms of cost, different markets have to consider different product solutions. If you want to take the cost, you can only connect the LED directly to the AC power supply. The power supply has zero cost and longevity. Long, the best solution.
