Decoding the Light Calibration System – How Algorithms Simulate Sunrise
The Harsh Reality
Even a 50K deviation in standard sunrise simulation lights can significantly reduce wake-up efficiency.
Optimization Tests
✅ 10,000+ sunrise spectra captured (California/Hawaii/Rainforest)
✅ AI-deconstructed golden parameters:
▸ Color temperature gradient (2600K→6300K)
▸ Flare ramp slope (0.2 lux/s)
▸ Red light threshold (>49.7%)
⚡️ Neuro-Light Rhythm: The Magic of 590nm Amber
Harvard Medical School (unverified study) suggests:
At <30 lux, 590nm light reduces ipRGC cell response to blue light, slowing melatonin breakdown.
Based on these findings, we optimized the Donut's photic respiration algorithm.
Pre-sleep transition: 590nm amber glow, Reduces blue light's melatonin suppression
Deep sleep guard: Complete darkness, Ensures sustained melatonin secretion
Wake-up preparation: Amber light ramps to 250 lux, Activates suprachiasmatic nucleus (SCN)
Core Principle: Light That Breathes Like Nature
Full-cycle color temp error ≤8%
LED decay rate <3% over 20,000 hours
Optimizations
🌀 High-transparency PMMA housing (without yellowing)
✨ Light-diffusing agent ratio refined
💡 Multi-channel Light Emission Architecture + Composite Diffusion / Collimation Optical Optimization
💡 High-Frequency PWM Dimming combined with Multi-layer Light Filtering
💡 High-Frequency PWM Dimming combined with Multi-layer Light Filtering
Every beam calibrated in pitch-black labs to match night's natural breath.
Through relentless testing, cold tech transforms into living, rhythmic light.
All for that perfectly gentle glow—where dawn is nurtured in darkness.
When night embraces Donut, you’ll witness how this breathing light guides you tenderly toward morning.
