Description

Technical Field

[0001] This utility model relates to the field of diode technology, and in particular to a pin-adjustable light-emitting diode. Background Technology

[0002] Light-emitting diodes (LEDs) are a common electronic component widely used in various electronic devices. As a new type of solid-state cold light source, LEDs are widely used in various billboards for advertising due to their full-color spectrum. However, prolonged use can cause corrosion of the LED pins, affecting the normal operation of the equipment.

[0003] Traditional LEDs typically have fixed leads. In practical use, if the leads are damaged, they are difficult to replace, often requiring the entire LED to be replaced, resulting in wasted resources and increased costs. Furthermore, traditional LEDs rely primarily on lead length or markings on the diode body to distinguish the positive and negative terminals. In cases where markings are unclear or the leads have been cut, polarity identification becomes difficult, easily leading to installation errors and affecting the normal operation of the LED.

A connecting component 3 is threaded into the internally threaded holes 6, and a power-connecting component 7 is provided on the top wall of the internally threaded holes 6. The connecting component 3 is electrically connected to the LED 1 through the power-connecting component 7. In summary, using a wrench, the threaded post 302 is screwed into the internally threaded hole 6 through the hexagonal post 303. The spring 702 ensures that the moving contact 703 and the copper plate 301 are in full contact, preventing poor contact due to loosening of the connecting component 3. The contact piece 701 is connected to the positive and negative terminals of the LED 1. Conducting electricity is achieved through the spring 702 and the movable contact piece 703, thereby conducting electricity to the pin 304 through the copper sheet 301, forming a circuit between the pin 304 and the LED 1. When the pin 304 is damaged, the connection component 3 can be quickly replaced, reducing resource waste and cost increases. The pin 304 with red paint is the positive terminal, and the pin 304 with black paint is the negative terminal. The positive and negative terminals of the pin can be quickly determined by looking at the paint color, which is convenient for use. Furthermore, the positive and negative terminals of the pin 304 can be quickly determined by looking at the positive and negative terminal markings 5.

[0020] A protective cover 4 is provided on the outer periphery of the fixed base 2. The protective cover 4 is fitted on the outer periphery of the connecting component 3 and protects the pin 304 to prevent the pin 304 from breaking.

[0021] The lower part of the mounting base 2 is provided with positive and negative polarity markings 5, which can quickly determine the positive and negative polarities of pin 304.

[0022] The power connection assembly 7 includes a stationary contact piece 701, a spring 702, and a movable contact piece 703. The upper side of the stationary contact piece 701 is installed on the inner top wall of the internal threaded hole 6. The stationary contact piece 701 is connected to the electrode of the light-emitting diode 1. The lower side of the stationary contact piece 701 is fixedly connected to the upper part of the spring 702. The lower part of the spring 702 is fixedly connected to the upper part of the movable contact piece 703. The stationary contact piece 701 is connected to the positive and negative terminals of the light-emitting diode 1. Conducting electricity is achieved through the spring 702 and the movable contact piece 703, thereby conducting electricity to the pin 304 through the copper sheet 301, so that a path is formed between the pin 304 and the light-emitting diode 1. Furthermore, the spring 702 ensures that the movable contact piece 703 and the copper sheet 301 are in full contact, preventing poor contact due to loosening of the connection assembly 3.

The lower part of the threaded post 302 is fixedly connected to the upper part of the hexagonal post 303. Using a wrench, the threaded post 302 is screwed into the internal threaded hole 6 through the hexagonal post 303, so that the copper sheet 301 comes into contact with the power connection component 7, thereby completing the installation connection.

[0024] One of the pins 304 has a red coating on the upper outer periphery, while the other pin 304 has a black coating on the upper outer periphery. The pin 304 with the red coating is the positive terminal, and the pin 304 with the black coating is the negative terminal. The positive and negative terminals of the pins can be quickly determined by looking at the coating color, which is convenient for use.

[0025] Working principle:

[0026] Using a wrench, screw the threaded post 302 into the internal threaded hole 6 through the hexagonal post 303. The spring 702 ensures that the moving contact 703 and the copper plate 301 are in full contact, preventing poor contact due to loose connection component 3. The stationary contact 701 is connected to the positive and negative terminals of the LED 1. Conducting electricity through the spring 702 and the moving contact 703, the copper plate 301 conducts electricity to the pin 304, forming a path between the pin 304 and the LED 1. If the pin 304 is damaged, the connection component 3 can be quickly replaced, reducing resource waste and cost increases. The pin 304 painted red is the positive terminal, and the pin 304 painted black is the negative terminal. The positive and negative terminals of the pin can be quickly determined by looking at the paint color, which is convenient for use. Furthermore, the positive and negative terminals of the pin 304 can be quickly determined by looking at the positive and negative terminal markings 5.
