2 results about "Zener diode" patented technology

The invention provides a light-emitting diode (LED), and a method for preparing the LED and a base of the LED, in particular to an LED. The LED comprises two spacing supporting legs, a Zener diode, a coating colloid and a plastic base. The Zener diode is arranged on one supporting leg, electrically connected with the supporting leg and electrically connected with the other supporting leg by a conductor wire. The coating colloid covers and completely shields the Zener diode and the conductor wire; furthermore, the plastic base accommodates and completely shields the coating colloid so that the grains can be arranged at the very center of the groove of the base, thus avoiding the Zener diode absorbing the light beam emitted by the grains. The coating colloid can protect the Zener diode before the plastic base is formed; furthermore, as the surface is a smooth arc, the plastic base can be attached to the coating colloid closely and is not easy to generate cavities when being formed.
