Description

Technical Field

[0001] The utility model relates to the technical field of light-emitting diodes capable of changing color, in particular to a light-emitting diode capable of changing color. Background Art

[0002] Light-emitting diodes (LEDs) can change color using a current-controlled circuit. They are a type of semiconductor diode that converts electrical energy into light energy; they are often abbreviated as LEDs. Like ordinary diodes, light-emitting diodes consist of a PN junction and also have unidirectional conductivity. When a forward voltage is applied to the 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, respectively, within a few microns near the PN junction, producing spontaneous fluorescence. Electrons and holes in different semiconductor materials occupy different energy states. The amount of energy released when electrons and holes recombine varies; the greater the energy released, the shorter the wavelength of the emitted light. Commonly used diodes emit red, green, or yellow light. Simply put, the color of the diode can be changed by varying the output current intensity.

[0003] Existing color-changing diodes are usually fixed naked on the surface of a circuit board, with the entire diode exposed to the outside. The diode itself is made of glass, which poses a risk of damage and breakage. Existing color-changing diodes need to be soldered between the wires and the circuit board, which is cumbersome to install and disassemble. When the diode is damaged, tools are required to re-solder the wires. Therefore, to address the above problems, a color-changing light-emitting diode is proposed. Utility Model Content

[0012] 1. In the utility model, by providing the connecting chamber, the first limiting groove, the spring, the limiting plate, the connecting rod, the fixing cover, the second limiting groove and the wear-resistant layer and other components, the fixing cover is first pulled upward to drive the connecting rod, the limiting plate and the spring to move upward, and then the color-changing diode is inserted into the second limiting groove. The wear-resistant layer can protect and fix the color-changing diode, preventing the color-changing diode from shaking in the second limiting groove. Then, the fixing cover is loosened. Under the action of the spring, the fixing cover and the connecting chamber are tightly fitted, and the color-changing diode is fully surrounded and protected, thereby solving the problem that the existing color-changing diode is usually fixed naked on the surface of the circuit board, and the entire diode is exposed to the outside. The diode itself is made of glass and there is a risk of damage and cracking.

[0013] 2. In the utility model, by setting the first circuit connection groove, the second cable connection groove, the connecting wire and the color-changing diode and other components, when the color-changing diode is engaged into the second limiting groove, the connecting wire at the bottom of the color-changing diode is aligned with the first circuit connection groove, and then the color-changing diode is completely engaged into the second limiting groove. The connecting wire above the color-changing diode can now be engaged into the second circuit connection groove. The circuit connection of the color-changing diode can be easily connected without welding, which is convenient for later replacement of the color-changing diode. It can be directly pulled out, thereby solving the problem that the existing color-changing diode needs to be welded between the wire and the circuit board, which is more troublesome to install and disassemble, and when the diode is damaged, tools are needed to re-weld the wire.
