TangDella

The application of infrared LED lamp beads in infrared therapy lamps has attracted much attention due to its non-invasiveness, safety and portability. It mainly uses infrared light of specific bands to penetrate tissues, promote blood circulation, relieve pain and inflammation.

1. Main bands and their functions 

The infrared spectrum is usually divided into near infrared (NIR), mid infrared (MIR) and far infrared (FIR). The following bands are commonly used in therapy lamps:

Near infrared (700nm-1400nm)
Common bands: 850nm, 810nm, 940nm
Features: Deep penetration depth (up to 5-10mm subcutaneous), directly acting on muscles and nerves, promoting cell repair and ATP generation.
Application: deep tissue repair, arthritis, muscle pain.

Far infrared (1400nm-3000nm)
Common bands: 1550nm, 2000nm
Features: Energy is absorbed by water molecules, producing a warming effect, promoting local blood circulation and metabolism.
Application: chronic pain, rheumatism, skin inflammation.

Near infrared band. Mainstream product types

(1) Portable physiotherapy equipment
Infrared LED protective gear
Such as waist support, knee pads, wrist guards, etc., with built-in 850nm/940nm LED arrays for local pain.
Advantages: lightweight, wearable, suitable for home use.

Handheld physiotherapy device
Small device that focuses on the affected area and is often used for joint or acupoint treatment (such as 810nm devices).

(2) Fixed physiotherapy lamp
Panel-type infrared lamp
Large-area LED array (mostly combined with 850nm and 940nm), used for back or whole-body physiotherapy.
Example: Medical-grade red light therapy panel (often paired with 660nm red light to enhance synergistic effects)


3) Multifunctional combination equipment
Red and blue light mixed therapy
Combining 660nm (red light) and 850nm (infrared), taking into account both epidermal repair and deep anti-inflammatory (such as acne treatment device)

3. Technology trends and differentiated design

Multi-band combination: such as 660nm+850nm+940nm mixed, covering different depth requirements.
Intelligent control: adjust power/time through APP to adapt to personalized treatment.
Safety optimization: add temperature sensor and automatic power-off function to avoid burns.

4. Notes

Wavelength selection: Near infrared is preferred for deep inflammation, and far infrared can be selected for surface thermal therapy.

 

TOP BENEFITS OF RED THERAPY LIGHTS

 Near-infrared therapy lamps (700nm-1400nm, especially 850nm, 810nm, and 940nm bands) affect cell metabolism through photobiomodulation (PBM), thereby improving a variety of symptoms. Its treatment and improvement effects have been verified by some clinical studies and practices. The following are the benefits of specific applications and regular use:

I. Symptoms and pains that can be treated or improved

1. Pain management
Muscle and joint pain

Arthritis (such as knee arthritis, rheumatoid arthritis): Near-infrared light can reduce inflammatory factors (such as IL-6, TNF-α), relieve pain and stiffness. Back pain/cervical spondylosis: By promoting local blood circulation, relax muscle spasms. 

Sports injuries (sprains, strains): accelerate tissue repair and reduce swelling.

Neuropathic pain: Sciatica, diabetic peripheral neuropathy: infrared light can stimulate nerve repair and relieve numbness and tingling.

2. Inflammation and wound repair
Chronic inflammation

Tendonitis (such as tennis elbow), bursitis: reduce inflammation by inhibiting proinflammatory mediators.

Trauma repair: Postoperative wounds, ulcers (such as diabetic foot): Near-infrared light promotes collagen synthesis and accelerates healing.

3. Skin problems
Acne and dermatitis

Near-infrared (often combined with red light 660nm) can kill Propionibacterium acnes and reduce sebaceous gland inflammation.

Scar softening: Inhibit scar hyperplasia and promote normal tissue regeneration.

4. Other applications
Fatigue recovery

Athletes or manual laborers use infrared therapy to reduce lactic acid accumulation and relieve muscle fatigue.

Sleep and mood: Some studies have shown that infrared light may regulate melatonin secretion and improve sleep disorders (more evidence is needed).

Benefits of regular use of infrared therapy products


1. Non-drug analgesia
Reduce dependence on analgesics (such as NSAIDs) and avoid gastrointestinal side effects.

2. Deep tissue repair
Near-infrared light penetrates 5-10mm and directly acts on muscles, joints and nerves. Long-term use can delay the progression of degenerative diseases (such as osteoarthritis).

3. Enhance local metabolism
Promote ATP production and microcirculation, and help remove metabolic waste (such as lactic acid and uric acid).

4. Safety and convenience
Non-invasive, radiation-free, suitable for long-term home care (need to control irradiation time and power).

 Precautions and contraindications

Applicable population: chronic pain patients, sports enthusiasts, postoperative rehabilitation.

Contraindications: Acute infection or bleeding sites, malignant tumor areas, pregnant women's abdomen, thyroid sites (controversial).

Usage recommendations: Single irradiation for 10-20 minutes, 2-3 times a week, and treatment (such as 4-8 weeks).

Avoid looking directly at the LED light source to prevent eye damage (near-infrared light is invisible but may damage the retina).


Application of Infrared LED Beads in Infrared Therapy Lamps: Common Wavelength Combinations and Product Types

Infrared LED beads are widely used in infrared therapy lamps due to their non-invasive nature, safety, and portability. These lamps utilize specific infrared wavelengths to penetrate tissues, promoting blood circulation, pain relief, and anti-inflammatory effects. Below are the common wavelength combinations, product types, and their applications.

1. Common Wavelength Combinations and Their Effects

Infrared therapy typically utilizes near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR). The most commonly used wavelengths include:

Near-Infrared (700nm–1400nm)

  • Common wavelengths: 850nm, 810nm, 940nm

  • Characteristics: Deep penetration (5–10 mm), directly affects muscles and nerves, enhances cell repair and ATP production.

  • Applications: Deep tissue repair, arthritis, muscle pain.

Far-Infrared (1400nm–3000nm)

  • Common wavelengths: 1550nm, 2000nm

  • Characteristics: Absorbed by water molecules, producing a thermal effect that improves blood circulation and metabolism.

  • Applications: Chronic pain, rheumatism, skin inflammation.

2. Main Product Types

    • Best for deep muscle/joint pain (e.g., arthritis).

(2) Dual-Wavelength Synergy

  • 660nm (red) + 850nm (NIR)

    • Ratio: 1:1 or 2:1 (more red light for skin repair).

    • Used in acne treatment + pain relief devices (e.g., Joovv Elite).

  • 810nm + 940nm (dual NIR)

    • Ratio: 3:2 (more 810nm for nerve repair).

    • Used in neuropathic pain devices.

  • 630nm (red) + 810nm + 940nm

    • Ratio: 3:4:3 (balanced for skin, blood flow, and muscles).

    • Used in full-body recovery panels (e.g., Mitored Pro).

  • 850nm + 1070nm + 1550nm

    • Ratio: 5:3:2 (deep healing + metabolic boost).

4. Key Considerations

  • Penetration depth: NIR (850nm) for deep tissue, FIR (1550nm) for thermal effects.
