Inside the Donut Creation | Colorway Journal: When Hues Become the Rhythm of Sleep's Breath
Through its acrylic dome, dynamic light source, and diffusion chamber, Donut brings colors to life—colors that breathe. Every detail had to be engineered not just for optical accuracy in sleep environments, but also to achieve a seamless fusion of two material layers under dynamic light. 📌Color Calibration Challenge When light passes through two different materials, it creates a delicate balance between transmittance and color shift. Our goal: maintain extreme color temperature accuracy with a dynamic precision of ±50K. 1. Acrylic Dome Problem: Standard PC domes turn greenish under 3700K warm... Read more...
Inside the Donut Creation | Precision Acoustics Through Dual-Driver Design— making every sleep-aid rhythm feel as natural as breathing.
Precision Acoustics Through Dual-Driver Design Core Innovation Employing dedicated woofer-tweeter units (two-way design), Donut surpasses single full-range drivers with: ✅ 30% wider dynamic range ✅ 55% lower THD (Total Harmonic Distortion) The 150–500 Hz range is a critical low-mid band to which human hearing is most sensitive — any crossover, phase, or transient mismatch can cause “frequency gaps” or “low-frequency smearing.” The Challenge: Bass Loss & Algorithmic Overcompensation 1. Frequency Gaps Single-driver systems have almost no response below 40 Hz, resulting in a lack of immersion for ultra-low-frequency effects such... Read more...

Inside the Donut Creation | Light Alchemy: Imbuing Night with the Genes of Dawn
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... Read more...

Inside the Donut Creation | In the Design of Donut Sleep Light, Fabric Is More Than a Sound Medium
In the Design of Donut Sleep Light, Fabric Is More Than a Sound Medium—It’s a Gentle Armor for Sleep After 87 rigorous material tests, we ultimately selected a dual-tone microfiber woven fabric—imbued with the tactile nostalgia of childhood linen, yet engineered for immersive acoustics. ▍ Why This Fabric? Breathable Structure: Cross-woven with dual tones, featuring 1,200+ micro-perforations per cm² for lasting ventilation without heat buildup. Triple-Layer Protection: → Nano-scale anti-mold coating for microbial & stain resistance → Anti-static treatment to minimize dust adhesion ▍ An Experiment Rooted in Childhood Our... Read more...
