LED displays are everywhere nowadays. They are colorful and bright, adding a lot of color to our lives. But have you ever wondered what these LED displays are made of? Today, let’s talk about the important components of LED displays – lamp beads.
One of the core components of LED displays is lamp beads, which are mostly cubes or cuboids and have a variety of specifications, such as 3535, 3528, 2835, 2727 (2525), 2121, 1921, 1515, 1010, etc. These lamp beads are made through a mature packaging process, that is, the chip is loaded into a metal bracket, filled with glue and dried. Their luminous surface is usually single-front luminous, and the lamp pins can be directly soldered on a PCB circuit board with a soldering surface.
LED lamp beads have various specifications and models to adapt to different application scenarios. In the field of indoor LED SMDs, common lamp bead specifications include 0505, 1010, 1515, 2121, 3528, etc. In outdoor applications, common models include 1921, 2525, 2727, 3535, 5050, etc. These numbers represent the size of LED light-emitting components. For example, 0505 means that the length and width of the LED component are both 0.5mm.
Detailed explanation of lamp bead specifications
The metric size of 0505 lamp beads is 0.5mm×0.5mm, and the industry abbreviation is 0505;
The metric size of 1010 lamp beads is 1.0mm×1.0mm, and the industry abbreviation is 1010;
The metric size of 2121 lamp beads is 2.1mm×2.1mm, and the industry abbreviation is 2121;
The metric size of 3528 lamp beads is 3.5mm×2.8mm, and the industry abbreviation is 3528;
The metric size of 5050 lamp beads is 5.0mm×5.0mm, and the industry abbreviation is 5050.
There are many well-known LED display lamp bead manufacturers in the world,
LED lamp beads are packaged in a variety of ways, including direct plug-in, SMD, high-power and COB LED lamp beads. At the same time, LED lamp beads are also colorful, including red, yellow-green, yellow, orange, blue, purple, pink and white.
When identifying the positive and negative poles of LED lamp beads, we can distinguish them by marking and structure. Usually, the positive pole will be marked as a small dot or triangle and will protrude outward; while the negative pole has no markings and is slightly shorter than the positive pole. If the positive and negative poles cannot be determined, we can also use a multimeter for testing.
Choosing a suitable LED lamp bead brand is crucial to improving the performance and life of LED products. When choosing a brand, we need to consider many factors to ensure that the selected brand meets our requirements.
Due to its structural limitations, direct-plug LED lamp beads are mainly used in outdoor products with spacings such as P10, P16, and P20. Surface-mount LED lamp beads are widely used in outdoor and indoor applications due to their regular structure, adjustable metal brackets, and various types. Whether it is outdoor P13.33, P10, P8 and other spacing, or indoor P1.875, P1.667, P1.53, P1.25 and other small spacing applications, surface-mounted LED lamp beads can meet the needs.
The development prospects of LED display module lamp beads are showing a positive trend. Driven by multiple factors such as technological progress, market demand growth and policy support, the performance of module lamp beads will continue to improve and the application field will continue to expand. In the future, we have reason to believe that LED display module lamp beads will play an important role in more fields and bring people a more colorful visual experience.
