PCB News - LED light circuit board manufacturer

An LED light circuit board is a flat lighting device that uses LEDs (light emitting diodes) as a light source and is usually presented in a thin design. It consists of basic components such as LED chips, driver circuits and PCBs (printed circuit boards). This structural design allows LED light panels to provide powerful lighting effects in a limited space with good heat dissipation and stability.

The manufacturing process for LED light circuit board involves several key steps, including design, material selection, PCB (printed circuit board) production, chip mounting, assembly, testing and packaging. Each step is described in detail below:

1.Material Preparation

Before manufacturing begins, suppliers need to prepare LED chips, PCBs, driver circuits, and other related components. These materials are the basis for ensuring the performance of LED light panels (e.g., high energy efficiency and stability).

2.PCB Fabrication

PCB is the core part of LED light circuit board. Through printing, drilling or etching, conductive wires are connected to the electrode positions on the PCB to ensure good electrical connectivity.

3.Chip Mounting

Using surface mount technology (SMT), the LED chips are fixed one by one in the specified position on the PCB. Chip pasting is usually done by automatic mounter to ensure precision and efficiency.

4.Assembly

During the assembly process, the LED light circuit board will be installed with driver circuits and other auxiliary components. This process requires strict process control to ensure that all components work properly.

5.Testing

After the light board is assembled, it needs to be tested for functionality and performance. This includes checking the brightness, color temperature and electrical parameters to ensure that the product meets the expected standards.

6.Packaging

The tested and qualified light boards will be packaged for transportation, usually with anti-static materials to protect the LED light boards during transportation.

The function of common LED lamp drive circuit board

1.Simple LED lamp driving circuit board with capacitive resistance step-down, rectification and filtering methods.

The circuit board of this way has a simple structure and saves costs, but the circuit is unreliable, the failure rate is high, and the life of the LED lamp is short.

2.LED constant voltage driver board.

LED constant voltage driver board,its circuit principle is equivalent to a switching power supply, which directly drives the LED lamp beads through the constant voltage output by the switching power supply.

The switching power supply converts 220V AC power through a rectifier bridge into a high-voltage DC power of around 310V,and then uses PWM modulation to turn on/off the switching tube at a high speed,forming an alternating current signal through a high-frequency transformer to output AC voltage,and then rectify and output DC power.

3.LED constant current source driver board.

The effect of driving the LED with a constant current source is the best, the brightness of the LED light circuit board is uniform and not easy to damage, and the service life is longer.

LED light circuit board has become an important choice for modern lighting with their unique performance and wide application prospects.With the development of technology and changes in market demand, LED light panels will continue to play its advantages in the field of lighting,providing efficient and high-quality light source for people's life and work. It will be an indispensable choice for both commercial lighting and home lighting.
