[0002] Tunnels need tunnel lighting even during the day. The lighting effect is closely related to road safety. If the brightness is constant, the eyes will be uncomfortable due to strong light when entering the tunnel, or the driver may not adapt to the light at the exit and cause glare, and the energy-saving effect is not good. In order to meet market demand, technical requirements for dimming and color-adjusting LED tunnel lights have emerged.

[0003] During the use of existing tunnel lighting, the illumination angle of the tunnel lighting is difficult to adjust. If the illumination angle of the tunnel lighting needs to be adjusted, it needs to be disassembled and reinstalled, making it difficult to achieve the effect of segmented dimming. In addition, tunnel lighting is generally installed by bolts. When the tunnel lighting fails, it needs to be disassembled one by one, which is time-consuming and labor-intensive. Therefore, we have introduced a new tunnel lighting segmented dimming device. Utility Model Content
