7. Precautions
①Storage conditions
Please follow the conditions below.
・Before opened: Temperature 5~30℃, humidity less than 60%RH
・After opened: Temperature 5~30℃, humidity less than 60%RH (Please apply soldering within 1 week.)
・Avoid exposing to air with corrosive gas.
If exposed, electrode surface would be damaged, which may affect soldering.
②Usage conditions
The products are not designed for the use under any of the following conditions.
Please confirm their performance and reliability well enough if you use under any of the following conditions;
・ In a place with a lot of moisture, dew condensation, briny air, and corrosive gas
(Cl, H2S, NH3, SO2, NOX, etc.).
・Under the direct sunlight, outdoor exposure, and in a dusty place.
・In water, oil, medical fluid, and organic solvent.
③Heat radiation
If the forward current(IF) is applied to single-state module at 360mA, there is a risk of damaging module
or emitting smoke.
Equip with specified heat radiator, and avoid heat stuffed inside the module.
Applying thermal conductive sheet or grease between module and heat radiator enables heat to radiate effectively.
④Installation
Material of board is alumina ceramic. If installed inappropriately, trouble of no radiation may occur due to
board crack. Please take particular notice of install method.
Further information on installation, refer to the following cautions.
・Apply ether screws or adhesives, or both of them when installed to heat radiator.
In case of applying adhesive only, check the effectiveness before fixing.
In case of screw, apply thread locker in order to prevent loosening.
If LED comes off from the heat radiator, unusual temperature rise entails hazardous phenomena including
device deterioration, coming off of solder at leads, and emitting smoke.
・Refer to recommended dimensions when installing with screws.
・Screw torque: Within 0.2Nm
If it is inefficient to tighten screws, apply locker to prevent loosening.
・It is recommended to apply screws which use low corrosive materials such as Stainless steel.
Avoid applying flat-head screws, which cause board crack due to applying stress to screw holes.
・Avoid convexly uneven boards.
Those convex boards are subject to crack when tightening screws.
・It is recommended to apply thermal conductive sheet or grease with adhesiveness and heat radiating-
adhesives, because of thermal and mechanical combination between module and heat radiator.
However, depending on their thickness, board crack may be entailed by warped board, which is
caused when tightening screws. So please check your actual conditions carefully as for the screw torque.
