The invention relates to the technical field of traffic signal lamps, in particular to a low-energy-consumption traffic lamp which comprises a light-emitting panel, a light guide plate, a first liquid crystal light valve and an LED lamp set, the light-emitting panel and the light guide plate are both made of transparent acrylic materials, a plurality of light guide points are arranged on an emergent surface array of the light-emitting panel and combined to form a traffic lamp signal pattern, and the first liquid crystal light valve is arranged on the emergent surface array of the light-emitting panel. At least two side faces of the light-emitting panel are incident faces, the surfaces of the incident faces are flat and smooth, one incident face is coupled with the emergent face of the light guide plate, the other incident face is coupled with the emergent face of the LED lamp set, the incident face of the light guide plate is coupled with the first liquid crystal light valve, and the face, away from the light guide plate, of the first liquid crystal light valve is used for receiving natural light. By adopting a combined adjusting mechanism of the liquid crystal light valve and the natural light, the environment light source is effectively utilized, the situation that high-power output of the LED lamp set is still depended on under the strong light condition in the daytime is avoided, and therefore energy consumption is remarkably reduced.

    本发明涉及交通信号灯技术领域,具体提出了一种低能耗型交通灯,包括:发光面板、导光板、第一液晶光阀和LED灯组,发光面板和导光板均为透明亚克力材质,发光面板的出射面阵列设置有多个导光点,多个导光点组合形成交通灯信号图形,发光面板的至少两个侧面为入射面,入射面表面平整光滑,其中一个入射面与导光板的出射面耦合,另一个入射面与LED灯组的出光面耦合,导光板的入射面与第一液晶光阀耦合,第一液晶光阀远离导光板的一面用于接收自然光。通过采用液晶光阀和自然光的结合调节机制,有效利用环境光源,避免在白天强光条件下仍依赖LED灯组高功率输出,从而显著降低能源消耗。
