Applications

Orthopedic & Sports Medicine Clinics
Used for non‑invasive management of knee osteoarthritis, ligament strains and post‑injury rehabilitation, complementing exercise therapy validated by PBM trials.

Vibration and heat modes help reduce stiffness and prepare joints for manual therapy or physical training sessions.

Physiotherapy & Rehabilitation Centers
Applied to enhance micro‑circulation, reduce pain and support muscle recovery after surgery or chronic overload.

Adjustable straps and cordless control allow use during passive mobilization or while patients perform functional exercises.

Pain Management & Wellness Clinics
Offers drug‑free adjunct treatment for chronic knee pain, neuropathic discomfort and age‑related degeneration, aligned with KOA PBMT evidence.

Multi‑modal design (light + heat + massage) enables clinics to build premium service packages and differentiate from standard heating pads.

Home‑Care, Telehealth & Corporate Health Programs
Suitable for supervised home use by elderly, office workers and athletes thanks to simple touch interface and fixed 30‑minute cycles.

Buyers can integrate into subscription or rental models with remote follow‑up on pain scores and mobility outcomes.

How It Works & Usage

• 660nm red light is absorbed by superficial tissues, promoting blood flow and modulating inflammatory mediators, while 850nm near‑infrared penetrates deeper into muscles, cartilage and synovium to support mitochondrial ATP production and pain reduction.

• Clinical and pre‑clinical PBM research indicates these wavelengths can help reduce knee pain and improve function when combined with structured rehabilitation exercise.

Usage：

• Wrap the HGHJ02 belt around the knee so LEDs are centered over the joint line, securing with straps for full contact but not constriction.

• Using the controller, select desired LED level (1–5), vibration mode (M1–M3) and heating level (1–3); start with moderate settings for 30‑minute sessions, 3–5 times per week over 6–8 weeks, adjusting based on patient tolerance and clinical assessment.

FAQs

Q1: Why Can’t I See All The Led Lights?
A: Some of the LEDs are Infrared light which is not visible to the human eye. If you see the red lights on, the unit is on.

Q2: Can I Customize The Flexible Pad?
A: Yes, you can present your custom demands including material, shape, sizes etc. My engineer team has helped to do custom services to other clients.

Q3: How Do I Use The Flexible Wrap?
A: You can connect the power supply to work or use the battery powered. Then press the button to operate. You can select the Continuous or Pulsed 10Hz frequency, the power intensity 1-3 levels adjusted.

Q4:Can the red light heating touch the skin directly? What is the difference between red light and ordinary heating belt?

38-48 ℃ temperature heating provided by the red light, red light directly in contact with the skin is good for the skin, better promote blood circulation, relieve pains. It will be safer than heating pad only provide heat. Takes 15 minutes to 48°C.

Q5. Can we customize the wavelength ratios and branding for our own private label?
Yes, OEM/ODM is our core strength. With 200+ patents and a dedicated R&D team, we can customize the LED ratios (e.g., increasing Blue light for dermatological brands), modify the chassis color, and print your logo. We can move from a design concept to a functional prototype in as little as 4–6 weeks.

Q6. Which medical and safety certifications are included for the portable series?
