Is it better to connect high-power LED chips in series or in parallel

Is it better to connect high-power LED chips in series or in parallel? How to choose?

This is a question that often arises in lighting engineering and electronic design. Different application scenarios and design requirements may determine whether you choose to connect high-power LED chips in series or in parallel. A professional LED lighting company will provide you with detailed answers:

一. Series connection of chips:

1.High stability: When you connect high-power LED chips in series, each chip is connected behind the previous one. This means that the current is the same and the voltage increases in order. The stability of the series circuit is higher, because if one chip fails, it will not affect the operation of other chips.

2.High voltage: The total voltage of the series circuit is equal to the sum of the voltages of each chip. This means that you can use a higher voltage to drive high-power LED chips, thereby reducing the current, reducing line losses, and improving efficiency.

Not suitable for applications requiring high brightness uniformity: Series-connected chips may not be suitable for applications that require multiple chips to have the same brightness at the same time, because a brightness problem with one chip may affect the brightness of the entire series circuit.

二. Parallel connection of chips:

1.Independent control: In a parallel circuit, each high-power LED chip has its own power circuit. This means that you can independently control the brightness and status of each chip, which is suitable for applications that require individual control, such as colored LED light strips.

2.Brightness uniformity: Parallel circuits are easier to achieve brightness uniformity because each chip has an independent power supply and is not affected by other chips.

3.Stable current: Due to the independent power supply of each chip, the current stability is higher, and the failure of one chip will not affect other chips.

The choice between series and parallel connection of high-power LED chips depends on your specific needs and design goals. If you pursue high stability, higher voltage, and lower current, series connection is a good choice. If you need independent control, brightness uniformity, and higher flexibility, then parallel connection may be more suitable. The final decision should be based on your specific project requirements and circuit design. I hope this information can be helpful to you!
