MultiLED Fan Controller Aparatus

Abstract

The present invention discloses a multiLED fan controller apparatus, which is provided with various addressable RGB (Red-Green-Blue) LEDs. Each addressable RGB LED is built in with an IC (Integrated Circuit) control chip, which is equipped with a one-wire bus control function and can be connected in a series freely. The LED fans are only provided with windows of a single input and a single output that all the addressable RGB LEDs can be controlled. In addition, all the addressable RGB LEDs are controlled individually by a controller to result in various lighting effects through the change in output signals. The lighting can be adjusted remotely by the controller, or can be adjusted by a dedicated software program.
