Principle of Brightness Detector Outside Tunnel Borehole

In the modern world of heavy traffic, tunnels have become a key link between different locations. However, the huge difference in light inside and outside the tunnel often causes visual disturbances to drivers, which in turn affects driving safety. In order to solve this problem, the tunnel brightness detector has been developed.

The tunnel brightness detector adopts optical sensing technology, just like the tunnel's "eyes", always monitoring the brightness outside the tunnel. Whether it is a sunny day or a dark night, it can sense the light intensity outside. More intelligently, it can automatically adjust the brightness of the lighting equipment according to the pre-set brightness standard, to ensure that the tunnel inside and outside of the light transition is natural, to avoid the driver due to sudden changes in light and discomfort.

The principle is: through the linkage with the lighting equipment to achieve automatic adjustment of brightness. Specifically, when the detector senses the change of brightness outside the tunnel, it will pass this information to the control system of the lighting equipment. The control system automatically adjusts the brightness of the lighting equipment according to the actual brightness outside the cave and the preset brightness standard. For example, when the detector senses that the brightness outside the tunnel is low, the control system will automatically increase the brightness of the lighting equipment to ensure that the tunnel is illuminated; conversely, when the brightness outside the tunnel is too high, the control system will reduce the brightness of the lighting equipment to avoid over-illumination resulting in energy wastage. This automatic adjustment mechanism helps to improve the lighting quality inside the tunnel and provides a more comfortable and safer driving environment for drivers.
