The invention relates to the technical field of electric bicycle lamps, in particular to an irradiation-angle-adjustable electric bicycle lamp which comprises a shell, a lampshade and a lamp holder. The lampshade is mounted on the shell; a lamp source is fixedly connected to the lamp holder; the shell is fixedly connected with a transverse adjusting frame; a moving block is connected to the transverse adjusting frame in a sliding manner; a light reflecting assembly is arranged on the shell; the reflecting assemblies are spliced into a reflecting cover and can swing along with the movement of the lamp holder, so that the focusing position deviation of light rays emitted by the lamp holder after the movement of the lamp holder is reduced; the first reflecting plate and the second reflecting plate enclose to form a cylinder to serve as a reflecting cover, and when the lamp holder drives the second fixing ring to move, the first reflecting plate and the second reflecting plate can swing along with the lamp holder, so that a light source emitted by the lamp holder is located in the middle of the second reflecting plate; and therefore, the condition that the focusing position of light emitted after the position of the lamp holder is changed deviates is relieved.

    本发明涉及电动自行车车灯技术领域,尤其涉及一种照射角度可调的电动自行车车灯,包括:外壳、灯罩和灯座;所述灯罩安装在所述外壳上;所述灯座上固连有灯源;所述外壳上固连有横向调节架;所述横向调节架上滑动连接有移动块;所述外壳上设置有反光组件;所述反光组件拼接成反光罩,能够随着所述灯座的移动而摆动,进而减少灯座移动后,灯座发出的光线聚焦位置偏移;本发明通过将一号反光板和二号反光板围成圆筒形,充当反光罩,当灯座带着二号固定环移动时,一号反光板和二号反光板能够随着灯座而摆动,从而使得灯座发出的光源位于二号反光板的中间位置,进而使得灯座位置改变后发出的光线聚焦位置偏移的情况缓解。
