Abstract: The present application discloses a controller mounting structure of a ceiling fan and a ceiling fan lamp using a DC brushless motor, including a control box disposed below the DC brushless motor of the ceiling fan, and a controller body disposed inside the control box and electrically connected to the DC brushless motor. The control box includes a metal upper case and a metal lower cover coupled with the metal upper case. The metal upper case is provided with a first switch for controlling clockwise and anti-clockwise rotation function of the fan, and a second switch for controlling rotating speed, gear shifting and stopping functions of the fan. The first switch and the second switch are independently connected to the controller body through electric wires respectively. The controller mounting structure can improve the cost-performance ratio of the DC brushless motor controller, and facilitate maintenance of the product.
