Now many friends are very concerned about the material of 7030 lamp beads and patch beads. Today, I will share the information of 7030 lamp beads and patch beads with you, hoping to help you.

With the development of science and technology, the application range of lamp beads is becoming wider and wider, especially in LED industry, and the material of lamp beads has become the focus of attention. Among them, 7030 lamp beads and patch lamp beads are widely used. What are the materials of these two lamp beads? This article will analyze this in detail.

What is the material of 7030 lamp bead

7030 lamp bead is one of the LED lamp beads, with a size of 7mm × 3mm, which is widely used in the market at present. The material of 7030 beads is silicon and aluminum phosphide, and the ratio of these two materials determines the brightness and luminous effect of 7030 beads.  


Silicon is a kind of semiconductor material with good electrical characteristics, which can control the flow of current. In the 7030 lamp bead, silicon is used as an n-type semiconductor material, which accepts electrons and produces photoelectric effect under the action of current, thus emitting light.

Aluminum phosphide is a conductive ceramic material with good thermal stability and corrosion resistance. 7030 lamp uses aluminum phosphide as p-type semiconductor material, which injects holes (lack of electrons) into silicon material and forms p-n structure with silicon material to realize the luminous effect of LED.

What material is the patch lamp bead made of?

The patch bead is a miniaturized LED lamp bead with a size of less than 1mm, which can be widely used in mobile phones, tablet computers, televisions and other electronic products. The materials of the patch lamp beads mainly include:

1. Aluminum substrate: Aluminum substrate is a metal substrate material with good heat dissipation performance, which can effectively reduce the temperature of LED bulbs and improve the life and stability of LED.

2. Glass substrate: As an inorganic nonmetallic material, glass substrate has high temperature resistance and transparency, which can protect LED lamp beads from the influence of external environment.

3. Ceramic substrate: Ceramic substrate is inorganic nonmetallic material, which has good high temperature and insulation, and can protect LED lamps from electric field.  

Difference between 7030 lamp bead and patch lamp bead

Although 7030 beads and patch beads are LED beads, there are certain differences in material, size and brightness.

1. Different materials: 7030 lamp beads are made of silicon and aluminum phosphide, while patch beads are made of aluminum substrate, glass substrate and ceramic substrate.

2. Different sizes: The size of 7030 lamp bead is 7mm × 3mm, while the size of patch lamp bead is generally less than 1mm.

3. Brightness difference: According to different materials and sizes, the brightness of 7030 beads and patch beads is also different. Generally speaking, the brightness of 7030 beads is higher.

How to choose 7030 lamp bead and patch lamp bead

7030 lamp beads and patch selection lamp beads should be selected according to specific applicable scenarios and requirements.

1. Application scenario: When the display screen with large luminous area or higher brightness is needed, it is recommended to select 7030 lamp beads. If you need miniaturized electronic products or lamp beads with low power consumption and high stability, it is recommended to choose patch beads .

2. Requirement characteristics: Lamp beads with adjustable brightness and color temperature are needed. It is recommended to choose 7030 lamp beads; If you need beads with special functions such as waterproof, dustproof, earthquake resistance and pressure resistance, it is recommended to choose beads for patch.

Future development trend of lamp beads

With the continuous development of LED technology, the future development trend of lamp beads will develop in the following directions:

1. Miniaturization: The size of lamp beads will become smaller and smaller, which can be widely used in more electronic products.

2. Intelligentization: The lamp bead will have more intelligent features, which can realize remote control, timing switch, automatic brightness adjustment and other functions.

3. High efficiency: The luminous efficiency of lamp beads will be higher and higher, which can achieve lower power consumption and longer life.  

In a word, the material and size of the lamp bead have great influence on the brightness and luminous effect of the lamp bead. Choosing the appropriate lamp bead can improve the quality and performance of the product.

The above is the detailed introduction of "What is the material of 7030 lamp bead and what is the material of patch lamp bead". What do you think? For details, please see the relevant suggestions below. The following is a summary of this article:

7030 lamp bead is an LED lamp bead composed of silicon and aluminum phosphide, with a size of 7mm × 3mm and higher brightness. The materials of the patch beads are aluminum substrate, glass substrate, ceramic substrate, etc., and the size is generally less than 1mm, which is suitable for miniaturized electronic products. Choosing the right marbles should be based on the specific application scenarios and requirements. In the future, the development trend of lamp beads will be miniaturization, intelligence and high efficiency .
