## Abstract

A photoelectric device includes an electrode structure, an LED (light emitting diode) element, a zener diode and a reflective cup. The LED element, the zener diode and the reflective cup are arranged on the electrode structure. The LED element and the zener diode are electrically connected in anti-parallel with each other. The reflective cup comprises an inner surface defined thereof and a nick defined in an outside of the reflective cup. The LED element is surrounded by the inner surface of the reflective cup and the zener diode is arranged in the nick.
