3535 IR LED,3V infrared diode,850nm SMD IR emitter,940nm infrared LED for scanner,810nm IR light source,biometrics IR LED,CCTV infrared fill lamp,barcode scan IR component
High voltage 3V 3535 dome lens IR LED with aluminum base, optional 810/850/940nm wavelength. Concentrated infrared beam for long-distance emission, SMT mountable, widely used in barcode scanning, access control, CCTV night vision fill light and industrial infrared sensing equipment.
Our 3535 3V high-voltage infrared SMD LED is designed with a spherical dome silicone lens and high thermal conductivity aluminum substrate, available in three mainstream infrared wavelengths: 810nm, 850nm and 940nm. The convex dome concentrates infrared light to realize longer effective irradiation distance, while the aluminum base ensures outstanding heat dissipation to slow light attenuation. Standard 3535 footprint supports fully automatic SMT patch and reflow soldering, an optimal infrared light source for scanning, biometric identification, security monitoring and optoelectronic sensing fields.
