The '4 LED Constant Current LED Module' is an LED lighting module that contains 4 LED lights and uses a constant current drive circuit to ensure that the current of the LED remains constant. Here are some key features related to this type of LED module:

4 LEDs: This indicates that the module contains four LED lights. Multiple LEDs are combined to provide higher overall brightness while maintaining a constant current to ensure stable brightness throughout their entire lifespan.

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

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 lighting applications that require relatively high brightness, such as indoor lighting, outdoor lighting, billboard lighting, landscape lighting, etc. Through constant current drive, the brightness of LEDs can be maintained consistently under different conditions, providing reliable lighting effects.

The specific specifications and performance characteristics may vary depending on different manufacturers and models. Therefore, if you need more detailed information about a specific "4 LED constant current LED module", it is recommended to check the manufacturer's product specifications or contact the supplier for more detailed information.
