● judgement criteria of failure for the reliability

※ iv:below 50% of the initial value

※ vf:over 20% of the upper limit value

※ ir:over 2 times of the upper limit value

note:measurement should be taken between 2 hours and after the test leds have been returned to

normal ambient condition after completion of each test.

part number:

● precautions for use:

1. temperature in use

since the light generated inside the led needs to be emitted to outside efficiently , a resin with hight light transparency is used, therefore, additives to improve the heat resistance or moisture resistance(silica gel,etc) which are used for semiconductors products such as transistors cannot be added to the resin.

conse, the heat resistant ability of the resin used for led is usually low,therefore, please be careful of the following points:

avoid applying external force,stress and excessive vibration to the resins and terminals at hight temperature. the glass transition temperature of epoxy resin ussed for the led is approximately 120-130℃. if the temperature exceeding the limit,the coefficient of liner expansion of the resin doubles or more compared to that at normal temperature and the resin will be softened.

and if some external force or stress is applied at that time, it may cause a wire damage.

2. soldering

after soldering,avoided applying external force,stress and excessive vibration until the products down to the room temperature(the same to termial leads).

3. designing

care must be taken to provide the current limiting resistor in the circuit so as to drive the led within the rated figures, also caution should be taken not to overload led with exorbitant voltage at the turning on and off of the circuit.

when using the pulse drive care must be taken to keep the average current withini the rated figures, also the circuit should be designed so as be subjected to reverse voltage when turning off the led.

4. storage

in order to avoid the absorption of moisture, it is recommended to solder led as soon as possible after unpacking the sealed bags.

5. anti-static electricity

as the blue, green, white and puples are sensitive to the esd, so during the handling, soldering , testing and packing process the anti-static measurements must be applied.otherwise the led will be damaged.
