What is the best lighting for no glare?
The best glare-free lighting combines optical design, smart positioning, and adaptive technologies:
1. Optics:
Use LED panels with microprismatic/batwing lenses to achieve UGR ≤ 19 (ideal for offices) or ≤ 16 (precision tasks).
Prioritize fixtures with uniform luminance distribution and high CRI (≥ 80).
2. Positioning:
Mount fixtures at heights/angles ensuring a cutoff angle ≥ 45° to hide direct light sources from view.
Use louvres, baffles, or recessed mounting to block high-angle glare.
3. Adaptive Systems:
Implement tunable white LEDs (3.000–6.500K) with dimming for circadian alignment and reduced contrast.
Integrate motion sensors or daylight harvesting to auto-adjust brightness.
4. Anti-Glare Materials:
Apply frosted diffusers, LC films, or nanostructured anti-reflective coatings to scatter harsh light.
For windows, use electrochromic glass to dynamically control glare from sunlight.
5. Outdoor Solutions:
Use full-cutoff fixtures with amber/PC-amber LEDs (minimizing blue light) to protect ecosystems.
Design based on luminance maps, not just illuminance.
