One Article Detailed Patch Glowing Diodes

Patch the glow diodes (Surface Mount LED, AbbreviationSMD LED) It is a common form of light -emitting diode packaging.Compared with the traditional plug -in diode,DMN5L06WK-7The patch luminous diode has the advantages of small size, lightweight, good impact resistance, and high reliability.It is widely used in various electronic equipment, lighting products, display and indicator lights.This article will introduce the principles, characteristics, applications, and manufacturing process of the glowing diodes of the patch.

1. The principle of the glowing diodes of the patch

Patch emitting diode is an electronic device based on semiconductor materials. The characteristics of semiconductor materials are used to form electrons by injecting electrons and holes.-The acupuncture is compounded to produce light emitting effects.Its internal structure includesPType semiconductor andNType semiconductor, formed between the twoPNKnot.Be inPNWhen a positive voltage is added to the knot, the electrons are fromNInject itPIn the area, the composite of the cave produces energy and releases the photon, thereby generating lighting effects.

Second, the characteristics of the glowing diodes of the patch

1. Small size: Patch glowing diode adoptionSMDPackaged, small size, easy to install and layout.

2. Good light emitting effect: The glowing diode is used in semiconductor material, which has high luminous effects and bright colors.

3. Energy -saving and environmental protection: The glowing diodes of the patch have the characteristics of low power consumption and long life, can effectively energy saving, and do not contain harmful substances.

4. Easy to control: The glowing diodes of the patch can control the brightness and color by adjusting the current, which has strong tunability.

5. Vibration resistance: The glowing diode is encapsulated in solid -state tubes, which has strong vibration resistance and suitable for various harsh environments.

Third, the application of the glowing diodes of the patch

Patch emitting diode is widely used in various fields, including but not limited to the following aspects:

1. Lighting field: Patch glow diode can be used for indoor lighting, car lighting, street lighting, etc.

2. Display field: Patching diode can be used forLEDDisplay, electronic screen, digital display, etc.

3. Electronic products field: Patching diode can be used in indicators, backlight sources, etc. in electronic products such as television, mobile phones, computers, etc.

4. Traffic signal field: Patching diode can be used for traffic signal lights, logo lights, rear lights, etc.

5. Indoor decoration field: Patching diode diode can be used for indoor decorative lights, holiday lights, etc.

Fourth, the manufacturing process of glowing diode in the patch

The manufacturing process of glowing diode in the patch mainly includes the following steps:

1. Semiconductor material growth: Seven through chemical gas (CVD) Or molecular beam extension (MBE) Waiting methods, grow the required semiconductor materials on the substrate.

2. Making chips: use of light engraving, corrosion, sedimentation and other processes to make semiconductor materials intoPNThe chip of the knot.

3. Packaging: Connect the chip to the metal base and pack it to form a patch to glow diode.

4. Testing and sorting: Test and sort the encapsulating patch glowing diodes to eliminate unqualified products.

5. Packaging and factory: Packing the test qualified patch glowing diode for packaging and selling it.

The glowing diodes of the patch are electronic devices with small size, good luminous effects, and energy -saving and environmentally friendly, with extensive application prospects.With the continuous advancement of technology, the performance and manufacturing process of glowing diodes will continue to improve, bringing more application possibilities to various industries.
