The invention relates to a multifunctional traffic signal lamp, which is applied to the field of road traffic signal control and comprises a signal lamp display and brightness control technology, a light illumination detection technology and a temperature detection technology. The brightness of the signal lamp can be adjusted according to the ambient light intensity, the brightness of the signal lamp can be adjusted according to the change of the ambient light intensity, the brightness of the signal lamp is correspondingly increased when the ambient light is brighter, and the brightness of thesignal lamp is correspondingly decreased when the ambient light is darkened. Therefore, the problem that the eyes of people are easily uncomfortable due to the existing constant-brightness signal lamp is solved. For an intersection with traffic electronic police, the situation that a red light on a video record is displayed as a yellow light due to the fact that the red light of a signal lamp istoo bright at night is avoided, and the problem of signal lamp dispute during law enforcement is avoided. The signal lamp display is driven by a direct-current power supply to emit light, and the situation that the signal lamp on the image is not turned on when the vehicle runs the red light illegally is avoided.
本发明是一种多功能交通信号灯,运用于道路交通信控制领域,包含有信号灯显示和亮度控制技术、光线照度检测技术、温度检测技术。本发明可根据环境光强度来调节信号灯发光亮度,信号灯可依据环境光强度的变化进行信号灯亮度调节,环境光越亮,则信号灯亮度相应调高,环境光变暗,则信号灯亮度相应调暗,以此克服了目前恒定亮度的信号灯存在的容易引起人们眼睛不适的问题。本发明对于有交通电子警察的路口来说,解决了因为夜间信号灯红灯过亮造成的抓拍图像、视频录像上红灯显示为黄灯的情况,避免了执法时出现的信号灯争议问题。本发明的信号灯显示采用直流电源驱动发光,不存在对车辆违法闯红灯抓拍时图像上的信号灯不亮的情况。
