Yunnan's first solar signal light "conducts" traffic

"5, 4, 3, 2, 1" with the number of traffic on the countdown timer, stop at the intersection of East Lake Road and the former new road motor vehicles in the order of traffic signals under the "command" to leave. Unlike traffic lights in other places, the traffic lights at the junction of Huanhu East Road and Qianxin Road are powered by solar energy.

"This is the first solar traffic light in Yunnan Province." Ding Jie, chairman of Kunming Liad Technology Development Co., Ltd., which installed solar traffic lights, said that the junction of East Lake Road and Qianxin Road belongs to the intersection of T-shaped roads. Since the area is not connected to the municipal power grid, the company has installed three directions of solar lights to “direct” traffic.

Compared with ordinary traffic lights, solar traffic lights are characterized by low carbon, environmental protection, and energy saving. In appearance, it is similar to an ordinary signal light, except that it has a row of solar photovoltaic panels on its support. These photovoltaic panels can store solar energy under sunlight and convert it into electricity to power traffic lights. Internally, crystalline silicon solar modules for solar traffic signals can be used for 15 to 20 years. There is no noise during power generation, and it can work normally in the environment from -40 degrees Celsius to +70 degrees Celsius. In normal times, excess energy can be stored in the battery, ensuring that the signal light can be used for six consecutive days of rainy weather, and that no personnel duties are required during operation.

The reporter noticed that there was a black brake mark on the road near the solar traffic lights at the intersection of East Lake Road and Qianxin Road. A passing driver said: “This is the driver saw the traffic lights and left here by sudden braking. The flow of traffic on this road is relatively small. When there is no traffic light, the average driver is rushed past with the accelerator and there is a certain amount of traffic. The safety hazard. Now that there are traffic lights, most drivers will follow the traffic rules."

Under conditions permitting, Kunming Liad Technology Development Co., Ltd. intends to install a video surveillance system on the solar traffic lights at the intersection of East Lake Road and Qianxin Road to further improve the traffic capacity of road junctions and ensure the smoothness and safety of road junctions. .
