Which one is more suitable, direct insertion LED beads or surface mount LED beads? How to choose, many people are not clear. Today, the editor will discuss this issue with you. Direct plug-in LED beads are a common electronic component that have pins that can be stopped by inserting them into sockets on circuit boards.

Introduction to Direct Insertion LED Beads: Composition: 2. Bracket: LED pins, conductive and supporting functions 3. Silver glue: adhesive and conductive 4. Gold wire: connects positive and negative poles and conductive Direct Insertion LED Beads Characteristics: Low energy consumption: High luminous efficiency (160MW) Rich color: Almost all visible light local applications Easy to use: No need for complex circuit design

Here are some common plug-in LEDs

3mm plug-in LED: The packaging diameter of this LED bead is 3mm, and the common working current is 20mA. They are commonly used in applications such as indicator lights, panel displays, and small lighting. 5mm plug-in LED: The packaging diameter of this LED bead is 5mm, which is also one of the most common plug-in LED specifications. They have high brightness and viewing angle, suitable for various lighting and indicator light applications. 8mm plug-in LED: This type of LED bead has a packaging diameter of 8mm and typically has higher power and brightness. They are suitable for applications that require higher brightness, such as outdoor billboards, indoor lighting, etc. 10mm plug-in LED: The packaging diameter of this LED bead is 10mm, and its larger size allows it to carry higher power and brightness. They are commonly used in high-power applications such as outdoor lighting, automotive lighting, and decorative lighting

The fundamental parameters of the directly inserted lamp bead are: lamp cup: normal brightness of 60-70 lm; Bubble lamp: The normal brightness is 80-90 lm. 1W red light, with a normal brightness of 30-40 lm; 1W green light, with a normal brightness of 60-80 lm; 1W yellow light, with a normal brightness of 30-50 lm; 1W blue light, with a normal brightness of 20-30 lm. Note: The brightness of 1W is 60-110lm; The maximum brightness of 3W can reach 240lm; 5W-300W is an integrated chip packaged in series/parallel, mainly depending on the current, voltage, and number of series and parallel connections. LED lens: PMMA, PC, optical glass, silicone (soft silicone, hard silicone) and other materials are commonly used for primary lenses. The larger the angle, the higher the light output efficiency. When using a small angle LED lens, the light should be emitted far away. Directly inserted LEDs with different wavelengths have different colors. If color differences are requested, the price will be high. Consumers without LED spectrometers find it difficult to consume products with pure colors. White light is divided into warm color (color temperature 2700-4000K), regular white (color temperature 5500-6000K), and cool white (color temperature above 7000K). Europeans prefer warm white red light: band 600-680, of which 620630 is mainly used for stage lights, 690 is close to infrared blue light: band 430-480, of which 460465 is more commonly used for stage lights. Green light: Band 500-580, with 525530 stage lights being more commonly used. LEDs with different emission angles have different emission angles. Special luminous angle, higher price.

Surface Mount LED is a type of LED bead that is packaged in a smaller and thinner form factor. Compared to traditional plug-in LEDs, it is more suitable for automated surface mount (SMT) processes on high-density circuit boards. The following are some common parameters of surface mount LEDs: Package size: The package size of surface mount LEDs is usually represented by codes indicating the size, such as 5050, 2835, 3528, etc. These codes represent the length and width of the package size. Working voltage: The working voltage of surface mount LED is usually between 2V and 3.4V, and the detailed value depends on the color and information of the LED. Working current: The common working current for surface mount LEDs is 20mA, but the detailed value may also be affected by the LED model and application requirements. Luminous colors: SMT LEDs can provide multiple luminous colors, including red, green, blue, yellow, as well as colorful and white light sources. Brightness: Brightness is the intensity of light emitted by a surface mounted LED, usually expressed in lumens (lm) or milliamperes (mcd). The detailed brightness depends on the LED model and application requirements. Angle: Surface mount LEDs typically have specific emission angles, with common angles including 120 degrees, 90 degrees, 60 degrees, etc. SMT LEDs with different angles are suitable for different lighting or display needs. Yield: The yield of surface mount LEDs refers to the proportion of products that meet specifications and quality standards during the consumption process, which affects the quality and variability of the products. 1W red light, with a normal brightness of 30-40 lm; 1W green light, with a normal brightness of 60-80 lm; 1W yellow light, with a normal brightness of 30-50 lm; 1W blue light, with a normal brightness of 20-30 lm. Note: The brightness of 1W is 60-110lm; The maximum brightness of 3W can reach 240lm; 5W-300W is an integrated chip packaged in series/parallel, mainly depending on the current, voltage, and number of series and parallel connections. LED lens: PMMA, PC, optical glass, silicone (soft silicone, hard silicone) and other materials are commonly used for primary lenses. The larger the angle, the higher the light output efficiency.

Green light: Band 500-580, with 525530 stage lights being more commonly used. LEDs with different emission angles have different emission angles. Special luminous angle, higher price.

Direct insertion lamp beads have relatively low power and are widely used in the home appliance industry and indicator lamp beads. Surface mount lamp beads are relatively large and are commonly used in indoor lighting, advertising display screens, outdoor lighting, and other central areas. Whether it's direct insertion LED chips or surface mount chips, you need to choose according to your product requirements
