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.
6. Heat Management
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.
The temperature surrounding the LED in the application should be controlled. Please refer
to the data sheet de-rating curve.
