2、 Do not clean the LEDs ty the ultrasonic. When it is absolutely necessary , the influence of ultrasonic
cleaning on the LEDs depends on factors such as ultrasonic power and the assembled condition. Ultrasonic
cleaning shall be pre-qualified to ensure this will not cause damage to the LED.
1、 Below the zener reference voltage V
the zener diode “breakdown .”If the vlotage tries to rise above V
to keep the voltage at exactly V
2、 When the LED is connected using serial circuit, if either piece of LED is no light up but current can not
flow through causing others to light down.. In new design, the LEDis parallel with zener diode, if either
piece of LED is no light up but current can flow through causing others to light up
1、 Heat management of LEDs must be taken into consideration during the design stage of LED
application.The current should be de-rated appropriately by referring to the de-rating curve found in each
product specification .
2、 The temperature surrounding the LED in the application should be controlled. Please refer to the data
sheet de-rating curve.
1、These products are sensitive to static electricity charge, and users are required to handle with care.
Particularly, if an current and or voltage which exceeds the Absolute Maximum Rating of Products is
applied, the overflow in energy may cause damage to, or possibly result in electrical destruction of, the
Products. The customer is requested to take adequate countermeasures against static electricity charge and
surge when handling Products.
2、Proper grounding of Products , use of conductive mat, conductive working uniform and shoes, and
conductive containers are effective against static electricity and surge.
3、Ground low-resistance areas where the product contacts, such as metal surfaces of the work platform,
with a conductive mat (surface resistance 10
