New OSLON UV 3535 Mid Power Products With Design Innovations and Leading Performance Enrich ams OSRAM's UV-C LED Portfolio

ams OSRAM introduced the OSLON® UV 3535 series of mid-power UV-C LEDs which meet customers’ requirements for longer lifetime, higher output power and easier system integration.

The OSLON® UV 3535 LEDs combine a compact design with leading efficiency and high quality, making them ideal for use in consumer or industrial applications such as water purification or air conditioning systems. These products show a typical output power of 40 mW at a drive current of 185 mA for the SU CULDP1.VC, and 75 mW at 350 mA for the SU CULEP1.VC.

The new package design with no cover glass and an integrated reflector improves the output by reducing optical losses and leads to a comparably high wall plug efficiency of 3.7%. The reflector collects the die’s emissions and directs the light forward with a viewing angle of 120°. A standard 3.5 mm x 3.5 mm footprint and the absence of cover glass and lens give system designers the flexibility to apply a standard UV-C lens and to optimize the light output for their application.

A further advantage of the new OSLON® products SU CULDP1.VC and SU CULEP1.VC is an excellent, application dependent, lifetime. The package also includes an ESD protection device and a transparent dielectric coating as a protective element, contributing to the robustness of the LED.
