The invention relates to a road traffic signal lamp panel with controllable light sensing and brightness, which belongs to the technical field of road traffic signal lamp control. The problem that a red signal lamp on an image turns yellow or white when an electronic police snapshots a vehicle running the red light can be solved. The lamp panel is composed of a lamp panel circuit board, a light-emitting driving circuit board and more than one photosensitive sensor with different functions, more than one photosensitive hole is formed in the lamp panel circuit board, and the photosensitive sensor is installed at the position of the photosensitive hole. The lamp panel circuit board is round, the front face of the lamp panel circuit board is a light-emitting face, and lamp beads are arranged according to the pattern of the traffic signal lamp. The light-emitting driving circuit board is installed on the back face of the lamp panel circuit board or integrated on the lamp panel circuit board, and the light-emitting driving circuit board can receive signals of the photosensitive sensor and control light emitting and light emitting brightness of the lamp panel.When the photosensitive sensor detects a change in ambient light or a flash, the light-emitting driving circuit board can control the light-emitting brightness of the lamp panel circuit board to change correspondingly.
本发明一种具备感光和亮度可控的道路交通信号灯灯盘,属道路交通信号灯控制技术领域。本发明能解决电子警察抓拍车辆闯红灯时图像上红色信号灯发黄或发白的问题。本发明是由灯盘电路板、发光驱动电路板、1个以上不同功能的光敏传感器组成,其中,在灯盘电路板上开有1个以上的感光孔,光敏传感器安装在感光孔位置处。上述中,灯盘电路板为圆形,其正面为发光面,由灯珠按交通信号灯的图案排列;发光驱动电路板安装在灯盘电路板的背面,或是发光驱动电路板集成在灯盘电路板上,发光驱动电路板可接收光敏传感器的信号,可控制灯盘发光及发光亮度,当光敏传感器检测到环境光变化或有闪光时,发光驱动电路板可控制灯盘电路板的发光亮度相应改变。
