

Do not clean the LEDs by 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

5. Circuit Protection



Below the zener reference voltage Vz, all the current flows through LED and as the voltage rises

to Vz, the zener diode “breakdown." If the voltage tries to rise above Vz current flows through

the zener branch to keep the voltage at exactly Vz.



When the LED is connected using serial circuit, if either piece of LED is no light up but current

can’t flow through causing others to light down. In new design, the LED is parallel with zener

diode. if either piece of LED is no light up but current can flow through causing others to light

up.
