The light source of the lighting system adopts daylight-type cold light source. The light is closer to daylight. The light source is all installed on the top. The angle between the light and the top surface is less than 45 degrees to ensure that the light is direct and does not produce diffuse reflection. It can simulate different weather conditions in the morning, noon, evening, and dusk, control the lighting of different light roads, and realize environmental simulation through the combination of various light colors.
