1. Product Introduction
The 810nm LED near-infrared light therapy helmet is a non-invasive brain therapy device designed to deliver targeted photobiomodulation to the head using near-infrared light. The helmet structure ensures even light distribution and comfortable wear during sessions. With adjustable power levels, multiple frequency options, and flexible timing control, the system is suitable for research use, wellness applications, and supervised home therapy aimed at supporting brain function and neurological health.

2. Wavelength Principle Introduction
The device operates at an 810nm near-infrared wavelength, which is known for its deeper tissue penetration compared to visible light. Near-infrared light can pass through the scalp and skull to reach cortical areas, where it may influence cellular energy metabolism and neural activity through photobiomodulation mechanisms. This wavelength is widely used in brain light therapy research due to its balance of penetration depth, safety profile, and stable energy delivery.

3. Application Scope and Usage Recommendations
This helmet is intended for brain wellness support, cognitive training, neurological rehabilitation assistance, and relaxation programs. Typical usage recommendations are 3–5 sessions per week, with each session lasting 15–30 minutes, depending on individual tolerance and goals. Users are advised to start with lower power and shorter sessions, gradually increasing duration as needed. The device is designed for repeated, controlled use under professional or guided supervision.

4. Function Introduction
The system includes four preset frequencies: 10Hz, 40Hz, 400Hz, and 4698Hz.
• 10Hz is commonly used in protocols related to memory support, mood regulation, migraines, and neurological balance.
• 40Hz is associated with memory enhancement and research related to Alzheimer’s disease, dementia, and Parkinson’s disease.
• 400Hz is mainly used in Parkinson’s-related research protocols.
• 4698Hz is applied in pain control, migraine, and injury-related programs.
Time is adjustable from 1–60 minutes. Power has four levels: 3.75W / 7.5W / 11.25W / 15W. Output mode supports 1–2000Hz continuous wave and pulse-width modulated wave adjustment.
