The reliability tests were designed to evaluate both package integrity as well as workability of product performance over time. 2. All samples have done well by competed test required and passed all the qualification criteria with zero failure. From design standpoint, this package is robust enough to meet it’s data sheet conditions. 3. Based on the food result shown on the above test, this product is qualified and released for market. Precaution for Use 1. Cautions • This device is a UV LED, which radiates UV light during operation. • DO NOT look directly into the UV light or look through the optical system. To prevent in adequate exposure of UV radiation, wear UV protective glasses. 2.

Static Electricity • The LEDs are very sensitive to Static Electricity and surge voltage. So it is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs. • All devices, equipment and machinery must be grounded properly. It is recommended that precautions should be taken against surge voltage to the equipment that mounts the LEDs. 4. Heat Generation • The powered LEDs generate heat. Heat dissipation should be considered in the application design to avoid the environmental conditions for operation in excess of the absolute maximum ratings. 07.04.2011 VL400-EMITTER 4 of 4
