TECHNICAL FOUNDATION
双层光架构
Visible rhythm light above. Integrated red/NIR support layer beneath.
看得见的光之下，还有一层你感受到的。
Every Harlowe light contains two independent but coordinated layers: a visible layer that adjusts color temperature and brightness to follow circadian rhythm, and an integrated red/NIR support layer. Both layers share the same hardware platform and run across the entire Anchor, Axis, and Ritual One collection.
每一盏 Harlowe 都包含两个独立的层：调节色温与亮度的可见光层，和内置的多光谱底层。两层共享同一套硬件。
1800K–5000K full spectrum, Ra 97+ color rendering, melanopic-calibrated. Follows the natural arc of the day automatically.

KEY PARAMETERS — VISIBLE RHYTHM LIGHT
上层 · 可见光参数
Light is the most powerful zeitgeber.
光，是空间里最重要的变量。
Intrinsically photosensitive retinal ganglion cells (ipRGCs) detect melanopic light (peak sensitivity ~480nm) and signal the suprachiasmatic nucleus (SCN) directly via the retinohypothalamic tract — the master clock of the human circadian system. Harlowe's visible rhythm light layer is designed around this pathway.

INTEGRATED RED/NIR SUPPORT LAYER
底层 · 多光谱
Multiple independent bands. One photobiomodulation foundation.
四个波段。一套完整的多光谱底层。
Photobiomodulation (PBM) is an academic field with decades of research history, studying how specific wavelengths of red and near-infrared light interact with cellular chromophores — particularly cytochrome c oxidase. Harlowe's integrated red/NIR support layer is based on peer-reviewed literature from this field, selecting bands studied for different tissue penetration depths.
四个波段，覆盖从可见红光到近红外。波段选择基于已发表的学术文献。
Part of a general wellness lighting system. Not a medical device.
通用光照系统的一部分。非医疗器械。
Red Light
红光
Skin surface and superficial tissue
皮肤表面与浅层组织
Absorbed by cytochrome c oxidase near the skin's surface. One of the most extensively studied wavelengths in the photobiomodulation literature, with thousands of peer-reviewed papers examining its interaction with cellular processes.
在光学文献中被广泛研究的波段。数千篇同行评审论文。
Hamblin MR, BBA Clinical, 2016
Deep Red
深红光
Intermediate tissue depth
中层组织深度
Bridges the gap between visible red and near-infrared. This wavelength has been studied for its ability to reach tissue layers beyond the skin surface while maintaining interaction with cellular chromophores.
可见红光与近红外之间的过渡波段。
de Freitas & Hamblin, IEEE JSTQE, 2016
Near-Infrared (NIR)
近红外
Deep tissue penetration
深层组织穿透
Invisible to the eye. Penetrates significantly deeper into the body than visible red wavelengths. Extensively studied in the photobiomodulation literature for its interaction with deep tissue layers. This is the primary wavelength behind Harlowe's overnight support mode.
肉眼不可见，穿透更深。Harlowe 夜间模式的主要波段。
Ferraresi et al., Photonics Lasers Med, 2012
Far Near-Infrared
远近红外
Deepest tissue penetration
最深层组织穿透
At the far end of the near-infrared therapeutic window. Studied for its ability to reach the deepest tissue layers, complementing the 850nm band. Together, the 850nm + 950nm combination provides the broadest deep-tissue coverage in the Harlowe system.
近红外远端。与 850nm 互补，提供最完整的多光谱覆盖。
Hamblin MR, BBA Clinical, 2016; Wunsch & Matuschka, 2014
THE PHOTOBIOMODULATION MECHANISM
光学研究基础
In peer-reviewed literature, the core mechanism of photobiomodulation is described as: specific wavelengths of red and near-infrared light are absorbed by cytochrome c oxidase (Complex IV) in the mitochondrial electron transport chain, interacting with cellular energy processes. This mechanism has been the subject of extensive peer-reviewed research published in journals including BBA Clinical, Photomedicine and Laser Surgery, and IEEE JSTQE.
红光与近红外的光学特性已被广泛研究。相关文献发表于 BBA Clinical、Photomedicine and Laser Surgery、IEEE JSTQE 等期刊。
Harlowe's multi-band architecture is built on this literature base, providing layered support depth within a general wellness lighting system.
Harlowe 的四波段架构基于这一文献基础。

全四波段启动。不可见，无声
Both layers work in concert but are independently controlled. Visible light follows circadian rhythm. The integrated red/NIR support layer activates automatically in the evening and overnight.
两层光各自独立控制。可见光层自动调节色温，多光谱层在夜间自动启动。
OPTIONAL SUPPORTING LAYER: SCENT
可选层 · 香氛
Olfactory signals reach the amygdala within 150ms — faster than any other sensory pathway.
嗅觉信号在150毫秒内到达杏仁核——比任何其他感官都快。
Lan Series is an optional scent accessory designed to pair with Ritual One. Four blends for different moments of the day. Within a light-first system, scent plays a quiet supporting role — reinforcing the rhythm signal of light, not replacing it.
兰系列是为 Ritual One 设计的可选香氛配件。四款配方对应一天中的不同时段。在以光为先导的系统中，香氛扮演安静的支持角色——增强光的氛围，而非替代它。
Light comes first. Everything else is supporting.
光是第一位。其他一切都是支持。
Herz, Chemical Senses, 2009
Lillehei & Halcon, J Alt Comp Med, 2014
OPTIONAL SUPPORTING LAYER: SOUND
可选支持层：声音
Sound provides temporal structure for the rhythm signal of light.
声音为光的氛围提供时间结构。
Binaural frequency differences accompany different states through auditory steady-state response (ASSR). Delta frequencies (0.5–4Hz) accompany nighttime rest; Alpha (8–12Hz) accompanies relaxed wakefulness; 40Hz Gamma accompanies focused work. Sound is a temporal companion to light, not an independent intervention.
双耳频差通过听觉稳态反应（ASSR）伴随不同状态。Delta频率（0.5–4Hz）伴随夜间休息；Alpha（8–12Hz）伴随放松清醒；40Hz Gamma 伴随专注工作。声音是光的时间伴侣，不是独立的干预。
