2835 SMD Near Infrared LED 800nm-1530nm Multi Wavelength Flat Lens High Radiant Power IR LED

This 2835 series multi-band near-infrared (NIR) SMD LED features standard dimension 3.5×2.8×0.65mm with single independent chip design, covering a wide therapeutic wavelength range from 800nm to 1530nm. Adopting high-quality vertical infrared bare die and pure gold wire bonding technology, it delivers stable high radiant power output with low thermal buildup. Flat wide-angle silicone encapsulation ensures uniform 120° beam distribution, making it the ideal core light source for professional medical phototherapy instruments, deep tissue rehabilitation devices, anti-aging beauty equipment and biomedical optical sensors.

1. Comprehensive Multi-Band Therapeutic Wavelength Coverage

   Available in multiple precise wavelength options: 808nm, 850nm, 940nm, 1064nm, 1310nm and 1530nm, covering the full effective spectrum for photobiomodulation (PBM) therapy. Different wavelengths penetrate to varying tissue depths to meet diversified medical and beauty treatment requirements.

2. Deep Tissue Penetration for Professional Medical Applications

   Near-infrared spectrum from 800nm to 1530nm can effectively penetrate deep into subcutaneous tissue, muscle and joint areas, supporting tissue conditioning, circulation improvement and cellular recovery, which is widely recognized in clinical phototherapy practice.

3. Standard 2835 Industry Footprint for Automated Production

   Universal 3.5×2.8mm package size is fully compatible with all automatic SMT pick-and-place equipment, simplifies PCB layout design and significantly reduces assembly cost for mass production of medical and beauty device manufacturers.

4. Stable High Radiant Power & Low Thermal Design

   Optimized chip structure and high thermal conductivity PCB substrate ensure stable radiant output under continuous long-hour operation. Low heat generation minimizes thermal risk to human tissue during prolonged treatment sessions.

5. Premium Raw Material for Reliable Long Service Life

   Pure gold wire bonding and high-grade infrared chip provide excellent anti-ESD performance and ultra-low lumen depreciation. Rated average service life exceeds 50,000 working hours, fully compliant with RoHS and REACH international environmental standards.
