1. How do you determine the required brightness for a road?

Brightness requirements depend on:

· Road category

· Traffic volume

· Safety requirements

· Local lighting standards

Professional designs consider illuminance (lux), luminance, and uniformity.

2. What is lux in street lighting?

Lux is the measurement of illuminance, representing the amount of light received on a surface.

3. What is the recommended lux level for roads?

Required lux levels depend on road classification and local standards. Different roads require different lighting levels.

4. What is lighting uniformity?

Lighting uniformity refers to how evenly light is distributed across the road surface. Higher uniformity improves safety and visibility.

5. What factors affect road lighting uniformity?

Factors include:

· LED optical design

· Installation height

· Pole spacing

· Beam angle

· Road width

6. How do you calculate solar street light spacing?

Spacing depends on:

· Pole height

· LED optical distribution

· Road width

· Required illumination level

Professional lighting simulation is recommended for accurate design.

7. What is the recommended pole height for solar street lights?

Pole height depends on lamp power and road conditions. Common heights include:

· 5 meters

· 6 meters

· 8 meters

· 10 meters

· 12 meters

8. Can solar street lights be installed on existing poles?

Yes. Existing poles can be reused if they meet structural requirements and installation conditions.

9. What is the recommended distance between poles?

Pole spacing depends on:

· Road width

· Pole height

· Lighting distribution

· Required brightness

10. Can one solar street light illuminate both sides of a road?

Yes, depending on road width and lighting design. Double-arm or optimized optical systems may be used.
