Tunnel brightness monitor Product Overview:

Tunnel brightness monitor is an efficient lighting control system designed to solve visual adaptation problems caused by differences in light and dark inside and outside tunnels.The Tunnel brightness monitor controller fully meets the requirements for overall tunnel lighting control. Its preset control mode allows for automatic switching of lighting switches based on light source measurements and pre-defined parameters, providing optimal tunnel lighting. Its design fully complies with CIE requirements for tunnel lighting measurements and meets the "Specifications for Ventilation and Lighting Design of Highway Tunnels." Furthermore, its overall design is fully capable of meeting the requirements of harsh outdoor working environments.

Tunnel brightness monitor Installation Method:

The Tunnel brightness monitor device is installed on the wall in a designated area within the tunnel. To avoid damage from accidents or vehicle debris, it should be installed at a height of approximately 4 meters, in a suitable location more than 10 meters from the tunnel entrance. It features high reliability and low maintenance. Utilizing the latest microprocessor technology, it operates fully digitally and is easy to install and debug.

Tunnel brightness monitor Product Features:

Corrected using a specially designed high-efficiency filter according to the CIE-specified human visual spectrum curve, conforming to visual characteristics.
