Equipped with a high-transmittance hemispherical dome lens and excellent thermal dissipation design, it provides uniform 120° wide-beam infrared output. This LED is the ideal core light source for professional deep tissue phototherapy instruments, security surveillance night vision systems, industrial optical sensors and biomedical detection equipment.
Core Competitive Advantages
1. 3W High Power with Superior Radiant Flux
Each LED delivers up to 500mW radiant power at 700mA operating current, providing strong infrared penetration capability that meets the demanding requirements of deep tissue phototherapy and long-range industrial sensing applications.
2. High-Purity Alumina Ceramic Thermal Package
High-thermal-conductivity alumina ceramic substrate offers far better heat dissipation performance than traditional plastic packages, effectively reducing junction temperature during continuous high-power operation, minimizing light decay and extending service life to over 50,000 hours.
3. Comprehensive 740nm~1050nm Wavelength Coverage
Available in 7 standard precise wavelength options: 740nm, 780nm, 800nm, 810nm, 850nm, 940nm and 1050nm, covering the full effective spectrum for photobiomodulation therapy, security surveillance and industrial optical sensing.
4. 120° Dome Lens for Uniform Wide-Area Irradiation
Hemispherical silicone dome lens shapes a precise 120° wide beam angle with uniform infrared distribution, eliminating hot spots and ensuring consistent treatment effect for phototherapy panels and reliable detection performance for sensing systems.
5. Premium Gold Wire Bonding for Reliable Performance
High-quality vertical infrared bare die paired with pure gold wire bonding technology provides excellent anti-ESD performance and stable photoelectric properties, ensuring consistent output even under harsh operating conditions.
6. Standard 3535 Industry Footprint for Automated Production
Universal 3.5×3.5mm package size is fully compatible with all automatic SMT pick-and-place equipment, simplifying PCB layout design and significantly reducing assembly cost for mass production.
