如何让灯具保持一致的亮度输出？关键在于微调输出电压……

在商场、酒店、商铺及建筑户外亮化等应用场所，长LED灯带的身影随处可见，它们有着轻盈灵动的特性，为商场增添了不少现代感和活力。

然而在实际应用过程中，长LED 灯带容易出现首尾亮度不一致的情况，具体来说，就是靠近电源端亮度较高，而尾部则明显暗淡，非常影响灯光效果。

However, in actual applications, long LED light strips are prone to inconsistent brightness at the beginning and end. Specifically, the brightness is higher near the power end, while the tail is obviously dim, which greatly affects the lighting effect .

为什么会出现这种情况呢？这是因为电流在通过灯带时，由于灯带内部电阻的存在，会产生一定的电压损失。而随着灯带长度的增加，电压损失也会逐渐增大，导致灯带尾部的电压降低，亮度变暗。

Why does this happen? This is because when the current passes through the light strip, due to the existence of internal resistance of the light strip, a certain voltage loss will occur. As the length of the light strip increases, the voltage loss will gradually increase, resulting in a decrease in the voltage at the tail of the light strip and a dimming of the brightness.

To address this application problem, Suretron/SCPOWER effectively compensated for the voltage loss at the tail of the light strip by fine-tuning the output voltage of the driving power supply, ensuring that the light strip maintains a stable and consistent brightness output.

微调输出电压还能更好地匹配LED灯带，客户可以根据LED灯带的实际电压来调节电源的输出电压，应用更加便利。

Fine-tuning the output voltage can also better match the LED light strip. Customers can adjust the output voltage of the power supply according to the actual voltage of the LED light strip, making the application more convenient.

Alleviate the impact of line loss on lamps

During the power transmission process, due to the physical properties of the power line itself, such as resistance, reactance, and inductance, electric energy is lost during transmission. This is the line loss problem.

应对线损问题，微调输出电压的方法能够有效补偿电流在传输过程中的衰减，确保灯具保持一致的亮度输出。

To address line loss issues, fine-tuning the output voltage can effectively compensate for the attenuation of current during transmission, ensuring that the lamp maintains consistent brightness output.
