medical sterilizing uv led 275nm 280nm led chip

Medical Sterilizing 6565 SMD UV LED RY-6565P SMD UV LED Datasheet:   Typical Electro-Optical Characteristics Curves:   Lens handling: Please follow the guideline to grab LEDs 1. Use tweezers to grab LEDs 2. Do not touch lens with the tweezers 3. Do not touch lens with fingers 4. Do not apply more than 4N of lens (400g) directly onto the lens Cautions: Don’t touch the LED’s face in case breaking wires down; oil on hand also absorbs deep UV! Always use tweezers and wear gloves during manual installation and wear eye protection during DUV LED operation. Use constant-current source specifically designed for DUV LEDs. Failure to properly re-adjust visible LED drivers will lead to severely damaged DUV LED, or shorten their usable life. DUV LEDs must not be allowed to operate without heat-sink. Always use good thermal compound to attach the backside of LEDs to the heat-sink, and taking care to avoid air bubbles in the thermal compound.  In consideration of the low reverse voltage and sensitive electric property, the reverse voltage would be high and the wires or the dies would be broken down if the anode and the cathode being used in the wrong way. Please do recognize the anode and cathode when using the DUV LEDs. DUV is harmful to your eyes, please do not watch closely or watch in a long time and do not observe through magnifying glass and microscope.
