Do you know how to choose the current and voltage of LED power supply?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.04.02
In the field of LED lighting, the selection of power supply plays a crucial role in the performance and stability of the entire system. The selection of current and voltage is an important part of it. How to correctly choose the current and voltage of LED power supply is a concern for many people. Here, we will delve deeper into this topic and use practical examples to help everyone better understand.



1. Understand the characteristics of LED

Different LED devices have specific current and voltage requirements.

Example: For example, common white light LEDs typically require a voltage of around 3V and a current of several tens of milliamps.

2. Determine current and voltage based on actual needs

When brighter light is needed, an LED power supply with a higher current and appropriate voltage can be selected.

Example: An indoor lighting system can choose a power supply that provides sufficient brightness.

3. Consider power factors and stability

The higher the power factor, the higher the efficiency of electricity utilization and the more energy-efficient it is.

Example: For a 10W LED light, a power source with a high power factor should be selected to reduce energy waste.

Stable current and voltage can extend the lifespan of LEDs and reduce light decay.

Example: For outdoor LED display screens, it is necessary to choose a high-power and good voltage stabilizing power supply.

Through the above introduction and example analysis, I believe everyone has a clearer understanding of how to choose the current and voltage of LED power supply. In practical applications, selecting the power supply reasonably based on specific needs and situations will ensure the normal operation and optimal performance of LED systems.
