ASHUR Tunnel LU102 Tunnel Illumination Monitoring Instrument(Tunnel-LU102)

1. Product Appearance 

2. Product Overview

As a special tubular structure, due to the large difference between light and shade inside and outside the tunnel, the driver is easy to produce "black hole" and "white hole" effect when entering and leaving the tunnel, which is easy to lead to the occurrence of traffic accidents.

ASHUR Tunnel LU102 Tunnel Illumination Monitoring Instrument plays a crucial role in assessing the brightness at the tunnel entrance, enabling the automatic adjustment of lighting based on environmental conditions. This system enhances the scientific and energy efficiency of tunnel illumination, ensuring both power savings and compliance with safety standards for tunnel driving. Furthermore, it fully adheres to the requirements set forth in the "Highway Tunnel Ventilation and Lighting Design Code."
