The invention belongs to the field of traffic signal lamps, and particularly relates to an energy-saving dimming signal lamp. The signal lamp comprises an ambient light detection device, a haze detection device, a traffic flow detection device and a light control device. The ambient light detection device is used for judging the ambient light intensity, the haze detection device is used for judging whether the weather is haze weather, the traffic flow detection device is used for recording the traffic flow condition in the past unit time, and the light control device adjusts the signal lamp according to the above conditions: when the number of vehicles is small at night, the brightness of the light emitting unit is reduced; when the haze weather or the traffic flow is large, the brightness of the signal lamp is improved to indicate safe passage. The signal lamp is fully combined with the road section, the time period and the environment, so that the indication effect of the traffic signal lamp is better played, and the environmental influence is reduced. And the load current of the LED is reduced in the dimming period, and the service life of the LED is prolonged, so that the service life of the traffic signal lamp is prolonged, and the energy utilization of the intersection signal lamp can be more accurately improved.

    本申请属于交通信号灯领域,尤其涉及一种节能调光信号灯。所述信号灯包括,环境光检测装置、雾霾检测装置、车流量检测装置、灯光控制装置;所述环境光检测装置用于判断环境光强度,所述雾霾检测装置用于判断是否为雾霾天气,所述车流量检测装置用于记录过去单位时间内车流量情况,综合上述情况所述灯光控制装置对信号灯进行调整:夜间车辆较少时,降低发光单元亮度;雾霾天气或车流量较大时,信号灯提升亮度,指示安全通行。通过信号灯与路段、时段、环境的充分结合,更好的发挥交通信号灯的指示作用,降低环境影响。降光时段降低LED的负载电流,延长了LED的使用寿命,从而延长了交通信号灯的使用寿命,能更精准的提高路口信号灯的能源利用。
