The invention discloses a traffic signal lamp, which is characterized in that display screens of the traffic signal lamp are divided into two groups according to different displayed direction symbols, the direction symbol displayed by one group of display screens is a straight-going symbol, the direction symbols displayed by the other group of display screens are a left-turning symbol and a turn-around symbol, the display screens in the same group are divided into a main display screen and an auxiliary display screen, each main display screen is divided into a direction symbol display area and a large color block display area, and the large color block display area of each main display screen integrates the display of three signals of a red lamp, a green lamp and a yellow lamp, that is, the large color block display area circularly changes according to the sequence of red, green and yellow and corresponds to the circular changes of the three signals of the red lamp, the green lamp and the yellow lamp. Under the condition that the size of the traffic signal lamp is limited, the requirement of separately displaying different guiding directions can be met, the red light signal, the yellow light signal and the green light signal in each guiding direction can be displayed as large as possible, various problems caused by the small visual area of the signal lamp in the prior art are solved, and the practical application can be realized.
一种交通信号灯,其显示屏按照所显示的方向符号的不同分为两组,其中一组显示屏所显示的方向符号是直行符号,另一组显示屏所显示的方向符号是左转符号和调头符号,在同一组显示屏中又分为主显示屏和副显示屏,每个主显示屏分为方向符号显示区和大色块显示区,每个主显示屏的大色块显示区都集成了红灯、绿灯、黄灯三种信号的显示,也就是按照红、绿、黄的顺序循环变化,对应于红灯、绿灯、黄灯三种信号的循环变化。本发明能在交通信号灯的尺寸有限的条件下既满足分开显示不同指引方向的要求,又使每种指引方向的红灯、黄灯、绿灯三种信号都得到尽可能大的显示面积,解决了现有技术因为信号灯的可视面积小而造成的种种问题,而且能够实际应用。
