This 3528 dual-spectrum SMD LED features dimension 3.5×2.8×1.54mm with six independent pins and two fully isolated internal circuits for red light and infrared separately. Equipped with 620~625nm visible red chip and 850~860nm near-infrared chip, each channel rated 0.1W at 20mA standard driving current, users can activate single red, single infrared or dual wavelengths simultaneously for flexible spectrum configuration. Adopting flat wide-angle silicone encapsulation and reliable heat-conductive PCB substrate, it delivers uniform 120° wide-beam light output, customized for portable facial beauty masks, wearable skincare wraps and compact household skin rejuvenation devices.
Two completely separated electric loops for Red(R+/R-) and IR(IR+/IR-), no electrical interference between two wavelengths. Independent power control enables arbitrary spectrum matching to satisfy diversified formulation requirements of various skincare equipment.
620~625nm visible red light accelerates skin surface cell turnover and improves skin complexion; 850~860nm near-infrared supports subcutaneous blood circulation and improves skin condition, ideal spectrum pairing for daily facial maintenance and household skincare phototherapy.
Low rated power at 0.1W per channel with standard operating current of 20mA, low heat generation during continuous long-hour working, perfectly matches compact wearable beauty wraps, lightweight facial masks and battery-powered portable skincare instruments.
Flat-top encapsulation brings uniform 120° wide viewing angle, seamless even light distribution without dark spots or local overheating, ensures consistent irradiation effect on curved facial and body skin surfaces.
Universal 3.5×2.8mm industry-standard 3528 package, fully compatible with automatic pick-and-place SMT machines, simplifies PCB layout design and reduces assembly cost for beauty device manufacturers during mass production.
Premium vertical LED bare die with pure gold wire bonding craft delivers outstanding anti-ESD performance and minimal lumen depreciation after continuous lighting. Rated service life ≥50,000 working hours and meets RoHS & REACH environmental compliance standards.
