Abstract
A highly reliable, high voltage AC/DC LED device with integrated protection mechanism is disclosed. The protection element can be a current-limiting resistor, monolithically integrated on LED chip, or a discrete resistor assembled in the lamp package or submount. The protection elements may also include other parts integrated on a submount.
