发明名称 Luminescent indication compass
摘要 A luminescent indication compass includes an electric power supply, a luminescent driver, a luminescent panel, a control panel, a voltage dropping circuit, and an electronic compass module. The electronic compass module may detect the signals of orientation and process the detected signals. Then, the processed signals may be output from the luminescent driver and may then be transmitted to the luminescent panel for indicating the present orientation to the user. Thus, when the luminescent indication compass of the present invention is mounted on the car, the driver may understand the present orientation of the car.
