Claim:
1. A head lamp device for wearing on a head and emitting lights outwardly, comprising: a cover member; a main control member, mounted in the cover member, a receiving unit and a control unit are embedded in the main control member, the receiving unit and the control unit are electrically connected with each other wirelessly or wired; a sensing member, electrically connected with the main control member and installed in the cover member, the sensing member is detecting an inclined angle of the head and generating a signal for being transmitted to the main control member and received by the receiving unit; at least two lamps, electrically connected with the control unit of the main control member, the lamps are controlled to turn on, turn off, adjust brightness, and change light-on/light-off priority of the at least two lamps by the control unit after the receiving unit of the main control member receives the signal; and a high-beam detector for detecting a front light source and a low-beam detector mounted on the cover member, the high-beam detector and the low-beam detector are electrically connected with the receiving unit of the main control member, the high-beam detector and the low-beam detector are detecting the brightness of the light source in front of the head and generating a light-source information to transmit to the receiving unit for being received, the control unit controls the brightness of the lamps based on the light-source information and then the lights emitted from the lamps are changed to be diffused or condensed; wherein the sensing member is detecting the change of the inclined angle via moving the head.
