Experimenting with RGBW Color Mixing
- jorlow 7y agoThis video talks about the quality of spectrum from various LED light sources and why it matters. IIRC they suggested amber LEDs in addition to white. https://youtu.be/5U-F7EhLp7g https://youtu.be/5U-F7EhLp7g
- Athrunen 7y agoThank you, I will definitely look into this.
- hackcasual 7y agoThat's what Philip's Hue system uses for it's color bulbs, a 5 color system. Third-party systems are usually referred to as RGB+CCT. I got some pretty dense strips from superlightingled for my recent kitchen lighting project, which were nice since they had all 5 colors on a single chip
- Athrunen 7y agoThanks for that information, was searching for "RGBAW" and got not that many results ^^
- hackcasual 7y agoYeah, you can sometimes find them under RGBWW, RGBWCW, RGBWWCW. This was the strip I went with for my lighting: https://www.superlightingled.com/dc24v-rgbcct-5in1-480leds-ultradense-series-5050smd-rgbww-flexible-led-tape-lights-164ft-per-reel-96ledsmeter-led-strips-p-2360.html https://www.superlightingled.com/dc24v-rgbcct-5in1-480leds-u... These are available in 12v: https://www.superlightingled.com/single-row-rgbcct-5in1-series-dc1224v-5050smd-300leds-rgbww-flexible-led-strip-lights-waterproof-optional-164ft-per-reel-p-886.html https://www.superlightingled.com/single-row-rgbcct-5in1-seri... Keep in mind, a lower voltage for the same light output means more current, so if you're doing a large build, spec your wire gauge accordingly.
- akdor1154 7y agoReally interesting.. would be great to see photographs of the effect of illuminating subtractive-colour pigments with this system.
- Athrunen 7y agoThanks, will try to take some in the near future.
- rcarmo 7y agoThis is timely, since I’m currently fiddling with an RGBW LED strip and having trouble mapping HomeKit’s HSL values.
