Two ways of experiencing light
Illumination • Look at people, objects • Less saturated colors • Changes slowly • Low spatial density • High spectral density • CRI – important, RGBWA • Collimated, Diffuse
• Electric lights, Daylight
– RGB is NOT sufficient
Infotainment • Look at the light • Saturated colors • Changes fast • High spatial density • Low spectral density • CRI – don’t care, RGB • Collimated, Diffuse
• Computer Display, TV, Rock
Concert – RGB is sufficient

The sky is a special case. It fits into both categories.

Next Generation Light Sources – now
• Remote on/off, dimming
• Fixed custom spectrum (non-blackbody)
• Warm-white, Cool-white “white tunable”
• RGB and beyond

Why go beyond RGB
• Broader CCT range at higher color quality
• Multiple solutions for a given chromaticity
• Larger gamut area
• Tradeoff between efficacy and color quality

What’s Next – Light Players
• Illumination has many dimensions:
– Intensity, spectrum, direction, beam angle, time
• A light player is to illumination as an MP3 player is to music.
• Record, Compose, Playback
• Some examples

Summary
• Products have moved beyond fixed CCT.
• Control interfaces are often complex.
• Light Players provide a simpler solution.
• Daylight provides a useful roadmap.
• The blackbody locus is a convenience.
• Clock, calendar time are key elements.
• Regular advancements on all fronts continue.
