摘要:
This invention relates to an ESD protection configuration and method for light emitting diodes (LED), including an LED an LED, having a p-n junction and connected to a circuit substrate, the circuit substrate having two p-type substrates and one n-type substrate therein; a first ESD protection configuration, built-in the circuit substrate and including a first resistor, a first capacitor and a first diode that are connected in series and then engage a parallel connection with the LED, wherein the first diode has a p-node connected to an n-node of the LED; and a second ESD protection configuration, built-in the circuit substrate and including a second resistor, a second capacitor and a second diode that are connected in series and then engage a parallel connection with the LED and the first ESD protection configuration, wherein the second diode has a p-node connected to the p-node of the LED, whereby such a configuration absorbs and removes ESD induced upon human contact and prevents the LED from burning to effectively extend the lifespan of the LED.
