Summary
This paper investigates how redistributing radiant power across visible wavelengths in LED sources influences key visual perceptions including color, brightness, and whiteness. Findings are directly applicable to LED lighting design decisions where spectral tuning must balance visual quality with other performance criteria such as circadian effectiveness.
Key Findings
- Spectral power distribution of LEDs significantly affects visual perceptions including color perception, brightness perception, and whiteness perception.
- Placement of radiant power at specific wavelengths can be optimized to influence different visual outcomes, suggesting trade-offs exist when designing spectrally tuned LEDs for multiple simultaneous goals.
