Abstract
Why and how we light?
WHY?
- To improve visibility
- To extend the day
- To enhance commerce and “urban” activities (leisure)
- To feel safer
- Primal fear of the dark
HOW to improve lighting?
Use warm Correlated Color Temperature (CCT): http://www.lrc.rpi.edu/programs/nlpip/lightinganswers/lightsources/whati…
Minimizing glare/blinding
Use white light allows lower illumination levels
Illumination level reduction can be done keeping the same target visibility: https://youtu.be/VrqOWTPX7eQ
Contrast matters (more that uniformity or lighting level)
