The invention relates to a variable-frequency display road traffic signal lamp, and belongs to the field of intelligent traffic control. At present, at a traffic signal lamp intersection provided with electronic police video monitoring, a red signal lamp is always displayed to be yellow or white and a green signal lamp and the yellow signal lamp are also displayed to be white on a video or a picture captured by an electronic police, which is caused by the fact that the signal lamps are too bright relative to electronic police video monitoring equipment; thus, as evidence for punishment of traffic violation, color distortion of the signal lamps on the image will affect punishment of the traffic violation. According to the invention, the frequency conversion technology and the commercial power frequency calibration synchronization technology are adopted for the light emission of the signal lamp, so that the display is normal when the signal lamp is lighted by human eyes, and the color is normal when the video monitoring equipment is watched; therefore, the problem that the traffic signal lamp is not matched with the electronic police video monitoring equipment to change color can be well solved.

    发明是一种变频显示道路交通信号灯,属智能交通管控领域。目前在设有电子警察视频监控的交通信号灯路口,信号灯在电子警察抓拍的视频或照片上,红色信号灯往往显示为黄色或白色,绿色信号灯、黄色信号灯也会显示为白色,这原因是相对于电子警察视频监控设备而言信号灯过亮所致。作为用于交通违法行为进行处罚用的证据,图像上的信号灯颜色失真将影响对交通违法行为的处罚。本发明通过对信号灯发光采用变频技术和用市电频率校准同步技术,在人眼看信号灯亮时显示正常,在视频监控设备上看色彩正常,能很好解决上述交通信号灯与电子警察视频监控设备不匹配而变色的问题。
