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
(1) Portable Therapy Devices
-
Infrared LED braces (e.g., waist belts, knee pads, wristbands)
-
Equipped with 850nm/940nm LED arrays for localized pain relief.
-
Advantages: Lightweight, wearable, suitable for home use.
-

-
Handheld therapy devices
-
Small, focused devices (e.g., 810nm for joint or acupoint therapy).
-

(2) Fixed Therapy Lamps
-
Panel-type infrared lamps
-
Large LED arrays (often combining 850nm and 940nm) for back or full-body therapy.
-
Example: Medical-grade red light therapy panels (often paired with 660nm red light for enhanced effects).
-

-
Desk/floor lamps
-
Far-infrared ceramic or LED sources (e.g., 1550nm) for gentle heat therapy.
-
(3) Multi-Wavelength Combination Devices
-
Red + Infrared combo therapy
-
E.g., 660nm (red) + 850nm (infrared) for skin repair and deep anti-inflammation (acne treatment).
-

-
Infrared + Thermal therapy
-
Far-infrared LEDs combined with heating elements (e.g., carbon fiber) for enhanced warmth.
-
3. Wavelength Ratio Configurations
Different wavelength combinations are optimized for specific therapeutic effects:
(1) Single-Wavelength Dominant
-
850nm (NIR)
-
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 .
-
-
810nm + 940nm (dual NIR)
-
Ratio: 3:2 (more 810nm for nerve repair).
-
Used in neuropathic pain devices.
-
(3) Triple-Wavelength Combination
-
630nm (red) + 810nm + 940nm
-
Ratio: 3:4:3 (balanced for skin, blood flow, and muscles).
-
Used in full-body recovery panels .
-
-
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.
