(1) Handling with care for this product

-When assembling the circuit board into the finished products, care must be taken to avoid

the component parts from touching other parts.

-Please avoid the resin area from being pressed, stressed, rubbed, come into contact with sharp metal nail

(e.g. edge of reflector part) because the function, performance and reliability of this product

are negatively impacted.

(2) Countermeasure against static electricity

-Handling of this product needs countermeasures against static electricity

because this is a semiconductor product.

-Please take adequate measures to prevent any static electricity being produced

such as the wearing of a wristband or anti-static gloves when handling this product.

-Every manufacturing facility in regard to the product (plant, equipment, machine, carrier machine

and conveyance unit) should be connected to ground and please avoid the product to be electric -charged.

-After assembling the LEDs into your final product(s), it is recommended to check

whether the assembled LEDs are damaged by static electricity (electrical leak phenomenon) or not.

-It is easy to find static damaged LED dies by a light-on test with the minimum current value.

(3) Thermal Design

-The thermal design to draw heat away from the LED junction is most critical parameter

for an LED illumination system. High operating temperatures at the LED junction adversely affect

the performance of LED’s light output and lifetime. Therefore the LED junction temperature should

not exceed the absolute maximum rating in LED illumination system.

-The LED junction temperature while operation of LED illumination system depends upon

thermal resistance of internal LED package (Rj-c), outer thermal resistances of LED package,

power loss and ambient temperature. Please take both of the thermal design specifications

and ambient temperature conditions into consideration for the setting of driving conditions.

-For more information, please refer to application note "Thermal Management".

(4) Driving Current

-A constant current is recommended as an applying driving current to this product.

In the case of constant voltage driving, please connect current-limiting resistor to each products in series

and control the driving current to keep under the absolute maximum rating forward current value.

-Electrical transient might apply excess voltage, excess current and reverse voltage to the product(s).

They also affect negative impact on the product(s) therefore please make sure that no excess voltage,

excess current and reverse voltage is applied to the product(s)

when the LED driver is turn-on and/or turn-off.

-For more information, please refer to application note "Driving".
