The "3 LED Constant Current LED Module" is an LED lighting module that contains three LED lights and uses a constant current drive circuit to ensure that the current of the LED remains constant. The following are some key features of this type of LED module:

3 LEDs: This indicates that the module contains three LED lights. This configuration is typically used to provide moderate brightness while ensuring a constant current for each LED.

Constant current: The constant current drive circuit ensures that the current of each LED lamp remains constant. This is crucial for ensuring the stability of brightness and color, especially in the event of power voltage fluctuations or temperature changes.

LED module: LED lights are usually integrated into a module, which may include circuits, heat sinks, and other necessary components to ensure that they can function properly in specific applications.

This type of LED module is typically used for various lighting needs that require moderate brightness, such as indoor lighting, billboard lighting, decorative lighting, landscape lighting, etc. Through constant current drive, the brightness of LEDs can be maintained consistently under different conditions, providing reliable lighting effects.
