This customized 3528 dual-wavelength SMD LED comes with dimension 3.5×2.8×1.13mm and six independent pins, built with two fully separated internal circuits for red light and infrared respectively. Equipped with 620~625nm visible red chip and 850~860nm near-infrared chip, each channel runs at rated 0.1W with standard 20mA operating current. Customers can activate single red, single infrared or dual wavelengths simultaneously to adjust mixed spectrum flexibly. Adopting flat high-transmittance silicone encapsulation and reliable heat-conductive PCB substrate, it provides uniform 120° wide-beam output, specially developed for lightweight facial beauty masks, flexible wearable skincare wraps and compact home skin rejuvenation instruments.
Two completely independent electric loops without cross-interference between red and infrared channels. Separate positive and negative pins support independent power supply for each wavelength, enabling arbitrary spectrum proportion matching to satisfy diversified skincare formulation requirements of different beauty devices.
620~625nm red light accelerates epidermal cell metabolism and balances uneven skin complexion; 850~860nm near-infrared improves subcutaneous blood circulation to optimize skin condition. This spectrum combination is widely applied for daily home cosmetic care and portable phototherapy equipment.
With low 20mA rated working current and 0.1W single-channel power, the LED generates minimal heat during long continuous operation, perfectly matching battery-powered lightweight facial masks and soft silicone wearable skincare wraps.
Flat-top encapsulation delivers seamless 120° wide-angle light distribution without dark spots or localized overexposure, ensuring consistent irradiation effect on curved facial and body skin surfaces.
Universal 3.5×2.8mm package size is fully compatible with automatic pick-and-place SMT equipment, simplifying PCB layout design and cutting overall assembly cost for beauty equipment OEM manufacturers.
High-quality vertical LED bare die together with pure gold wire bonding ensures outstanding anti-ESD performance and ultra-low lumen depreciation after long-hour continuous lighting. Average service life exceeds 50,000 working hours and meets RoHS & REACH international environmental standards.
