25.04.2012 led375 -66 -60- 110 2 of 2 precau tion for use 1. cautions ? this high power led must be cooled! ? do not look directly into the emitting area of the led during operation! 2. soldering conditions ? do not apply any stress to the lead particularly when heat. ? after soldering the leds should be pro tected from mechanical shock or vibration until the leds return to room temperature. ? when it is necessary to clamp the leds to prevent soldering failure, it is important to minimize the mechanical stress on the leds. 3. static electricity ? the leds are very sensitive to static electricity and surge voltage. so it is recommended that a wrist band and/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 ? 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 tem perature 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 ra tings given in the specification. ? the operating current should be decided after considering the ambient maximum temperature of leds. 5. storage ? the leds should be stored at 30c or less and 60%rh or less after being shipped and the storage 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 transitions in ambient temperature, especially in high humidity environments where condensation can occur.
