How do LED fans work?
Here’s how ceiling fans with LED lights work. There’s an electrical current that illuminates the light-emitting diodes via a microchip, resulting in visible light. In the process, the LEDs produce a small amount of heat, which is absorbed into small heat tanks and then dissipated into the surrounding air.

The fans are mainly intended for use in advertisement and marketing in shopping malls, airports or other public areas.
Can you turn off LED fan?
But of course, even tho it can be set to multiple colors and blinking patterns, it’s impossible to turn off the lights of the led fans. You can turn off the fan’s rotation completely, but not the lights.

How do you Mark polarity on LED sign?
When marking the polarity, remember that the leds will be connected positive to negitive and will be the number of leds we calculated for series earlier. Next, put the legs of the leds through the proper holes. Hold the led tightly and bend the leads over so the led is securely held in place.
