The night road traffic light signal system in the port comprises a red, green and yellow signal light 4 which is mutually switched under the control of a traffic control system; red green yellow signal lamp 4 buries underground 1 meter behind the intersection traffic direction stop line 3 in the harbour, in practice, red green yellow signal lamp 4 is outside 0.5m behind stop line 3, can within 3m, to the container truck of general height, red green yellow signal lamp 4 is outside 1m behind stop line 3, only slightly low head can see red green yellow signal lamp 4 in sitting in the driver's cabin, red green yellow signal lamp 4 also can be seen to the forward or backward movement a bit, to the container truck of superelevation, red green yellow signal lamp 4 also can be seen in 3m department behind stop line 3. In this embodiment, the red, green and yellow signal lamp 4 is a strip-shaped lamp, the width of which can be set on site, and generally 10cm to 40cm is used in consideration of the visual effect on the driver and the cost of the lamp, and in this embodiment, the strip lamp with the width of 20cm is set after the above conditions are comprehensively considered. A light-transmitting cover 4-5 with the plane consistent with the ground plane is arranged on the surface of the red, green and yellow signal lamp 4. The red, green and yellow signal lamps 4 are in the shape of a strip and are consistent with the length of the stop line 3. The red, green and yellow signal lamp 4 comprises a tricolor LED array forming light band 4-1 which is embedded in an underground light source groove 4-3, a reflecting cover 4-2 is further arranged in the light source placing groove 4-3 towards the tricolor LED array forming light band 4-1, a light transmitting cover 4-5 is high-strength light transmitting glass which is embedded in a notch of the light source placing groove 4-3, and a lamp groove shoulder protector 4-4 is further arranged on the light source placing groove 4-3, faces outwards, and is aligned with the light transmitting cover 4-5.

In this embodiment, the nighttime road traffic light signal system in the port includes the presentation mode and the intelligent control system that adopt red green yellow signal LED lamp area, and red green yellow signal LED lamp area carries out the switching of red green yellow signal under the control of intelligent control system.

The red, green and yellow signal LED lamp strip can use a common high-power luminous LED lamp strip.
