The invention provides a warning lamp with an adjustable width range. The warning lamp comprises a shell, a circuit board, a light source, a spectroscope and a shading piece. The circuit board is electrically connected with the light source and installed in the shell, and light emitted by the light source penetrates through the spectroscope and can be converged into a warning line. The shell further comprises a sliding groove, and the anti-dazzling screen is movably arranged in the sliding groove. When the position of the anti-dazzling screen is moved in the sliding groove, the size of the window of the shell can be adjusted, and then the length of a warning line formed by light rays emitted by the light source penetrating through the spectroscope is adjusted. In addition, a camera is further arranged in the shell, and a warning light area which is emitted by the light source, penetrates through the spectroscope and is formed on a projection surface can be recognized in an image recognition mode. When an obstacle on the projection surface crosses the warning light, the camera sends a signal to the alarm device through the circuit board; then the alarm device can send out an early warning signal such as sound buzzing or light source color changing, and therefore the good guiding and warning effect is achieved.

    本发明提供了一种可调节示宽范围的警示灯,包括壳体、电路板、光源、分光镜和遮光片,其特征在于:所述电路板与光源电连接,并安装设置于壳体内,所述光源发射的光线穿过所述分光镜可汇成一警示线;所述壳体还包括一滑槽,所述遮光片可活动设置于滑槽中。当在滑槽移动遮光片位置时,可调节壳体的视窗大小,进而调节光源发射的光线穿过所述分光镜汇成的警示线长度。另外,壳体内还设有摄像头,可以通过图像识别的方式识别出由光源发出透过分光镜后在投影面上所形成的警示光线区域,当投影面上出现障碍物越过警示光线时,摄像头会通过电路板发送信号给警报装置,警报装置会发出如声音蜂鸣或改变光源颜色的预警信号,进而起到良好的引导和警示作用。
