In winter, cold temperatures, gusts and snow showers swept many parts of the country. Under the snowy conditions, handling the road problems is not easy, and the security issue is real.
Improve driver and pedestrian safety
Modern lighting technologies are improving the safety of pilots and pedestrians on winter roads.
Traditional high-pressure sodium lamp illumination produces a lower color rendering index (CRI <25) and distorts the driving environment, while solid-state wide-spectrum illumination provides a higher CRI (CRI> 70) and better field of view.
Solid state broad spectrum lighting uses products with higher color temperatures (CCT typically 3,000K to 6,000K) and color rendering index (CRI> 70); solid state wide spectrum illumination improves road visibility and object detection. Light with a low color rendering index may “distort” the environment.
Compared with the traditional HID lamp technology, such as the 2000K CCT high-pressure sodium lamp, vehicle and pedestrian detection can be improved with broad-spectrum illumination of 4,000K color temperature.
LED and colder climate
In the often snowing area, LED is the ideal choice for road lighting.
The LED system is designed to provide the driver with excellent object detection and contrast in snow conditions, with appropriate levels and light curtain brightness, and the reflective properties of light scattered on the snow-covered pavement increase the ambient brightness and illuminate the pavement.
A common question is that Whether LED is ideal for traffic and street lighting because it does not melt snow?
Road lighting is usually horizontal-oriented optical system, anti-snow, if the lighting design is reasonable, interference is almost no problem.
There is a similar problem with lighting in parking lots and other outdoor spaces. Parking lots and roads usually clear snow, but ambient light levels increase due to the reflective nature of white surfaces. The LEDs can be adjusted to these luminance to provide a safer environment for pedestrians and pilots.
In the weakest months of the year, LEDs are a great way to increase visibility and maintain road safety. When bad winter weather comes, strong lighting design and appropriate color temperature create the best conditions for the pavement.
