Radio frequency antenna with optical function, and lighting device and spotlight using same

The invention provides a radio frequency antenna with an optical function, and a lighting device and a spotlight using the same. The radio frequency antenna with the optical function comprises an optical lens or a lamp bowl, and further comprises a lamp, a driving circuit board and a shell. The bottom of the optical lens is coated with a metal reflective coating, or the outward reflective surface of the lamp bowl is coated with a metal reflective coating, and the antenna or the signal transceiving element of the driving circuit board is connected with the metal reflective coating or the optical lens. The metal reflective coating can serve as an antenna or enhance the signal transceiving capability of the antenna, thereby reducing or overcoming the problem of signal interference caused by environmental factors or small size of the antenna. 本发明提出一种具有光学功能的射频天线及应用其的照明装置和射灯，其中，所述具有光学功能的射频天线包括光学透镜或灯碗，还包括灯、驱动电路板和壳体。所述光学透镜的底部涂有金属反光涂层，或者，所述灯碗朝外的反光面涂有金属反光涂层，所述驱动电路板的天线或者信号收发元件与所述金属反光涂层或光学透镜连接。金属反光涂层能够充当天线或者加强天线的信号收发能力，从
