As a key component in the LED lamp bead packaging process, LED lamp bead brackets are of various types and have their own characteristics. The following are several common types of LED lamp bead brackets and their differences:
Types of LED lamp bead brackets
1. Direct plug-in bracket:
- Features: Direct plug-in brackets are the earliest and most common type of LED brackets. Their design allows LED lamp beads to be directly inserted into the circuit board for soldering. This type of bracket usually has longer pins, which is convenient for manual or automatic plug-in machine operation.
- Application: Widely used in low-power lighting occasions such as indicator lights and signal lights.
2. SMD bracket:
- Features: SMD brackets use surface mounting technology. LED lamp beads are directly soldered on the circuit board through the pad without the need for jacks. This bracket is small in size and light in weight, suitable for high-density installation.
- Application: It is widely used in backlight sources, display screens, automotive lighting and other fields.
3. High-power bracket:
- Features: High-power brackets are designed for high-power LEDs and have good heat dissipation performance and high current carrying capacity. This type of bracket usually uses copper or aluminum as the base material and is equipped with a heat sink and heat dissipation structure.
- Application: Mainly used in outdoor lighting, industrial lighting, stage lighting and other occasions that require high brightness and high reliability.
4. Flat bracket:
- Features: The flat bracket structure is relatively simple, usually a flat metal plate or ceramic plate, used to fix the LED chip and provide heat dissipation. This bracket has good heat dissipation performance, but poor flexibility.
- Application: Used in some special optical designs or packaging processes.
5. COB (Chip on Board) bracket:
- Features: The COB bracket directly encapsulates multiple LED chips on a substrate to form an integral light source module. This bracket has the advantages of high light efficiency, high reliability, easy installation and maintenance.
- Application: Widely used in commercial lighting, home lighting, landscape lighting and other fields.
Differences between different brackets
1. Structure and design:
- Different types of brackets have significant differences in structure and design. For example, the plug-in bracket has a longer pin and is suitable for plug-in installation; while the patch bracket uses surface mounting technology and is suitable for high-density installation.
2. Heat dissipation performance:
- High-power brackets and flat brackets usually have better heat dissipation performance because they use a larger heat dissipation area and a special heat dissipation structure. In contrast, the heat dissipation performance of the plug-in bracket and the patch bracket may be slightly inferior.
3. Current carrying capacity:
- High-power brackets have a higher current carrying capacity and are suitable for driving high-power LED chips. The current carrying capacity of the plug-in bracket and the patch bracket is relatively low, which is suitable for low-power lighting occasions.
4. Application scenarios:
- Different types of brackets are suitable for different application scenarios. For example, the plug-in bracket and the patch bracket are suitable for low-power lighting occasions such as indicator lights and signal lights; the high-power bracket is suitable for outdoor lighting, industrial lighting and other occasions that require high brightness and high reliability; COB brackets are widely used in commercial lighting, home lighting and other fields due to their high light efficiency and easy installation and maintenance.
5. Cost and price:
- Different types of brackets also differ in cost and price. Generally speaking, high-power brackets and COB brackets are relatively expensive due to the high material cost and complexity of the manufacturing process; while direct-insert brackets and patch brackets are relatively cheaper.
In summary, there are many types of LED lamp bead brackets, each with its own characteristics. When choosing a bracket type, it is necessary to comprehensively consider factors such as specific application scenarios, performance requirements, and economic costs.
