06.07.2011 XHL-375-SD 5 of 5 precaution for use 1. cautions ? this device is a uv led, which radiates intense uv light during operation. ? do not look directly into the uv light or look through the optical system. to prevent inadequate exposure of uv radiation, wearing uv protective glasses is recommended 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. 3. heat generation ? thermal design of the end product is of paramount importance. please consider the heat generation of the led when making the system design. the coefficient of temperature increase per input electric power is affected by the thermal resistance of the circuit board and density of led placement on the board, as well as other components. it is necessary to avoid intense heat generation and operate within the maximum ratings given in the specification. ? the operating current should be desided after sonsidering the ambient maximum temperature of leds. 4. storage ? the leds should be stored at 30c or less and 70%rh or less after being shippedand the sorage life limits are 3 months. if the leds are stored for 3 months or more, they can be stored for a year in a sealed container with nitrogen atmosphere and moisture absorbent material. ? please avoid rapid transistions in ambient temperature, especially in high humidity environments where condensation can occur.
