After more than twenty years in foreign trade, I have handled quite a few logistics-park lighting projects. Many parks report that after the street lights are turned on, the middle of the road is very bright while the sides remain relatively dark, giving drivers an uneven field of view at night. This "bright center, dark sides" issue affects both comfort and safety. Drawing from practical experience, here is how to effectively improve it.
Optical Design Is the Core
Many street lights use ordinary optics that concentrate light directly under the pole, resulting in a bright center and darker edges. Choosing products from a professional LED street light manufacturer that offer bat-wing or asymmetric light distribution suited to the road width can spread light more evenly across the entire pavement and significantly improve illuminance on both sides.
Installation Height and Spacing Must Match
If the poles are too low or the fixture spacing too wide, even good luminaires can still produce a bright center and dark sides. Road width, pole height, and spacing need to be considered together. An experienced LED lighting OEM manufacturer will usually provide more reasonable layout recommendations based on actual road conditions rather than simply offering standard products.
Balance Power and Luminous Efficacy
Simply increasing power does not solve the uniformity problem and can sometimes make the center even brighter. Selecting high-efficacy fixtures with precise optics often achieves better overall illuminance uniformity at a more appropriate power level. At the same time, choosing an LED lighting supplier with a 5-year warranty provides better product stability and long-term light-decay control.
Anti-Glare and Visual Comfort
An overly bright center can also create glare that feels harsh to drivers. Quality luminaires improve side illuminance while also incorporating anti-glare design, making the overall lighting environment more comfortable and safer.
Recommend On-Site Calculation
The most reliable approach is to perform a simple lighting calculation based on road width, pole height, target illuminance, and uniformity requirements, or to refer to successful cases from similar projects. Experienced manufacturers can provide more practical fixture selection and layout proposals.
Conclusion
The "bright center, dark sides" problem on logistics park roads is mainly solved through professional optics, proper pole height and spacing, and stable quality. Selecting a reliable LED street light manufacturer and a capable LED lighting OEM manufacturer-especially an LED lighting supplier with a 5-year warranty-makes the improvement more lasting.
