When this line suddenly encounters an electrostatic discharge situation, the electrostatic protection diode grain 2 a can be instantaneous. Collapse and provide a low-impedance path, and the instantaneous current flowing to the gallium nitride light-emitting diode grains 1 a is diverted to the electrostatic protection diode grain 2 a, and the gallium nitride light-emitting diode crystals Grain 1 a is protected. However, the material of the electrostatic protection diode grain 2 a is mainly silicon si 1 i con). Theoretically, silicon material has the physical characteristics of absorbing specific light below 1.5 μm, and the wavelength range of visible light is generally It is about 400 nanometers to 700 nanometers, and the wavelength range of ultraviolet light is 10 to 400 nanometers. According to the actual experience of the creator, the conventional light emitting diode packaging structure 9 a The electrostatic protection diode crystal 2 a is installed, and the brightness is attenuated by 15 to 20%. In addition, due to the position relationship of the electrostatic protection diode crystal 2 a, the electrostatic protection diode is easily caused. The bulk crystal grain 2 a absorbs more blue light, which causes white light of different degrees to be formed above the electrostatic protection diode grain 2 a and above the gallium nitride light emitting diode grain 1 a, resulting in the conventional light emitting diode. The light emitting color of the package structure 9a is uneven. The reason is that the creator feels the above-mentioned shortcomings. It is an intensive study and cooperation with the application of theories to propose a rationally designed, extensive and effective improvement of the above-mentioned original creations. [New content] The main purpose of this creation is to provide a light-emitting diode packaging structure that can not only be protected against static electricity, but also improve brightness and eliminate uneven light emission.
