As is well-known, led tunnel lamp is a new type of lamps developed by led technology. Compared with traditional tunnel lighting, led tunnel lamps have the advantages of low light decay, high color rendering and long life, so they are loved and supported by everyone. However, due to the various aspects of data owned by different led tunnel lights, users need to focus on the following aspects when choosing.
1.Brightness
Led tunnel light is specially placed in the tunnel, because the brightness outside the tunnel during the day is much brighter than the tunnel, so when the driver drives into the tunnel, the visual need for a certain amount of adaptation time, to be able to see the situation inside the tunnel, otherwise there is no appropriate transition will be prone to black hole phenomenon, bringing safety risks to the driver. In order to avoid the occurrence of such phenomena, the selection of led tunnel lights needs to be fully determined according to the brightness outside the tunnel, the speed and the field of view of the entrance and the length of the tunnel.
2.Luminance Uniformity
If the brightness difference between the field of view inside and outside the tunnel is large, then the bright part will form a dazzling light source, and at the same time, there will be a certain stroboscopic effect, which makes the visual effect worse and increases the visual fatigue. Therefore, when selecting led tunnel lights, it is necessary to consider the average brightness inside the tunnel to ensure the uniformity of brightness, in order to avoid the continuous or repeated “zebra effect” on the road surface.
3.Dazzling Light
Because the formation of dazzle is a high brightness or brightness contrast in the field of view, it will reduce the visual function or make the eyes feel uncomfortable. Therefore, when choosing tunnel lights, it is necessary to fully consider the degree of glare of led tunnel lights, and try to choose the truncated led tunnel lights, which can form diffuse reflection, so that the light is very soft into the human eye.
In short, the choice of led tunnel lights need to fully consider the brightness, brightness uniformity and glare degree, in addition to the need to consider the strobe effect and lighting control and other factors.
Under the premise of fully considering these factors, it can better ensure that the relevant requirements of tunnel lighting are met, so as to improve the safety of drivers driving in the tunnel.
