3535 UVC LED Diode 270-275nm 10-15mW Dual Wavelength SMD Chip for Air and Water Disinfection
Product Highlights
- Germicidal UVC Output (270-275nm): Emits in the optimal microbial DNA/RNA absorption band, delivering 10-15 mW radiant flux (@100mA) for rapid, chemical-free sterilization with up to 99.9% bacterial inactivation.
- Dual Wavelength Design: Innovative integration of deep UVC (275nm) germicidal action with visible purple indicator UVA (395nm) in a single package, effectively solving invisible UVC safety concerns.
- High-Power 3W in Compact 3535 Package: Robust Inorganic 3535 (3.5×3.5mm) AlN ceramic substrate construction with eutectic bonding ensures superior thermal dissipation, low light decay, and extended operating stability.
- Low Voltage & Low Power Consumption: Operates safely at forward voltages of 5-7V. Generates minimal heat, making it easy to drive with standard DC circuitry and lithium battery modules.
- MERCURY-FREE Construction: Contains zero mercury, avoiding toxic disposal issues associated with traditional UVC lamps. Safe for consumer and commercial deployment worldwide.
- Instant Start Without Warm-Up: Full output at switch-on, suiting repeated disinfection cycles in automated and portable applications.
