Abstract: The present invention discloses a tower-shaped LED module that comprises a base, at least three LED panels mounted on the base and a bracket used to support the LED panels, wherein the LED panels are fixed on the bracket to form a pyramid. The present invention solves the traditional problem of the LED panels not secured firmly or shifting around easily. To fix the LED panels on the designed bracket, first slide each LED panel upward into sliding slots. Then insert each electrode pin of the LED panels into a corresponding pin hole in the base. Next put a screw though the base and fasten it to a supporting rod. At last solder the electrode pins of the LED panels to a printed circuit board on the bottom surface of the base. The whole assembly process is very simple and the assembled LED panels have good stability.
