LED Highway Lighting Standards
- Jul 10, 2019-
Good highway lighting enhances driving safety by providing a fully-illuminated roadway surface with no lighting gaps and dark spots that require a motorist’s eyes to adjust to different lighting conditions as he or she proceeds down the road. LED highway lighting can be configured to give highways a more uniform illumination that could not be achieved with traditional halogen or high pressure sodium highway lights.
Specifically, LED light sources can be configured to spread light from oval or circular patterns through narrow strips of lighting. Depending on the width of the highway, LED fixtures will be mounted at various heights and on poles that are either at the highway roadside or in median strips. On- and off-ramps and curves can be equally well-lit with different fixture patterns and lighting distributions.
Further, LED highway lighting comes o full illumination almost immediately after being powered up. Traffic control engineers can adapt LED highway lighting systems for a near-instantaneous response to changing weather or daylight conditions. A large number of highway accidents occur at dusk or just before dawn, when lighting conditions are variable and rapidly-changing. LED highway lights eliminate visibility problems at these and other times throughout the day.
