Description

Technical Field

[0001] The utility model relates to the technical field related to diode structures, in particular to an LED light emitting diode with a protective structure. Background Art

[0002] A light-emitting diode is a type of semiconductor diode that can convert electrical energy into light energy. Like ordinary diodes, a light-emitting diode is composed of a PN junction and also has unidirectional conductivity. When a forward voltage is applied to the light-emitting diode, holes injected from the P region into the N region and electrons injected from the N region into the P region recombine with electrons in the N region and holes in the P region within a few microns near the PN junction, respectively, to produce spontaneously radiated fluorescence. The energy states of electrons and holes in different semiconductor materials are different. The more energy released when electrons and holes recombine, the shorter the wavelength of the emitted light. Commonly used diodes are those that emit red, green or yellow light.

[0003] Light-emitting diodes are usually installed on circuit boards for use. In actual use, an outer shell is usually used to protect the circuit board. The light-emitting diode is protected by a transparent protective cover installed on the outer shell. However, when the outer shell is in use, the air inside cannot circulate and convective air cannot be formed, resulting in low heat dissipation efficiency. In addition, the conventional outer shell cannot provide shock-absorbing and buffering protection for the circuit board inside it, and thus the protection effect of the light-emitting diode is poor. In view of the shortcomings of the existing technology, those skilled in the art have proposed an LED light-emitting diode with a protective structure to solve the problems raised in the above background.
