Tunnel LED lighting technology witnesses the development of transportation in major countries, and ceramic heat dissipation technology breaks through strongly
As a semi enclosed tubular area, tunnels have some special characteristics. For example, when vehicles enter a tunnel during the day, due to a sudden drop in brightness and delayed human eye response, it is difficult to distinguish the situation ahead, forming the so-called "black hole effect"; On the contrary, when vehicles exit the tunnel, they will form the so-called "white hole effect" due to strong glare.
