Embodiment Construction

[0031] Fig. 2a is a plan view showing the structure of a multi-color light emitting diode package, designated as reference numeral 20, in accordance with a preferred embodiment of the present invention. Fig. 2b is an equivalent circuit diagram of the multi-color LED package shown in Fig. 2a.

[0032] As shown in FIG. 2a, the multi-color light-emitting diode package 20 of the present invention includes four terminals including an anode terminal A and three cathode terminals C1, C2 and C3. The multi-color light-emitting diode package 20 may include a red light-emitting diode 24, A green light emitting diode 22 and a blue light emitting diode 25.

[0033] The red light emitting diode 24 is formed with a first electrode (shown as a circle) on its upper surface and a second electrode (not shown) on its lower surface. Each of the blue light emitting diode 25 and the green light emitting diode 22 is configured such that a first electrode (shown as a circle) and a second electrode (s...

Abstract

Disclosed herein is a multi-color light emitting diode package. The multi-color light emitting diode package mounted thereon with at least three light emitting diodes comprises a substrate formed at the upper surface thereof with a pattern including three first terminals, and a single second terminal, first and second light emitting diodes, the diodes being mounted on a conductive mount pattern extending from the second terminal, and all formed at their upper surfaces with first and second electrodes, and a single zener diode chip having two zener diodes, the zener diode chip being mounted on the conductive mount pattern, and formed at a lower surface thereof with a single second electrode, and at an upper surface thereof with two first electrodes.

Description

technical field [0001] The invention relates to a package for displaying multiple colors of light-emitting diodes, more specifically a package structure of light-emitting diodes, which can increase the stability of pulses and electrostatic discharges, and can improve the miniaturization of design packages degree of freedom. Background technique [0002] In general, light emitting diodes are widely used in the field of light emitting devices and display devices because of their advantages of high brightness, relatively long usage time, low power consumption and ability to allow miniaturization. [0003] Light-emitting diodes can be used as a single package, and such a package is built so that multiple light-emitting diodes are mounted on a single substrate to emit many different colors according to user requirements, forming a multi-color light emission. diode package. The multi-color LED package mainly takes the form of a three-color LED package that combines red, green, a...
