Product Description

Veinasa-CDP-22 Tunnel Brightness Light Intensity Detector Luminance Photometers for Tunnel Vision Luminance Detection System

Product Description

Why we need a tunnel brightness detector:

When the driving vehicle runs in the tunnel with sharp changes in light and darkness, because the visual sensitivity can not immediately adapt, visual impairment is easy to occur, endangering driving safety, then we need to change the light intensity inside the tunnel to achieve the same or close to the illumination inside and outside the tunnel, and ensure that the driver's vision can reach a normal state when the driving vehicle enters the tunnel.

 

The function of tunnel brightness detector:
 

Tunnel brightness detector, using the most advanced VLSI technology, proprietary digital analog hybrid communication technology and designed a fully intelligent detection instrument. The luminance detector has advanced technology, high stability, communication and alarm functions, easy installation and maintenance, and is widely used in the luminance detection of tunnel entrance to achieve automatic lighting control.
