3W Green LED Chip on Aluminum Star Heatsink
The 3W SMD LED chip with green light, mounted on a star-shaped aluminum heatsink, is a compact solution for DIY projects, replacing light sources, or building custom lighting fixtures. The metal support efficiently dissipates generated heat, extending the diode's lifespan. Visible polarity markings on the board facilitate quick and correct connection to the power supply.
What you get with this product
- Intense and uniform green light — suitable for signaling, technical decorations, or electronic experiments
- Integrated aluminum heatsink prevents overheating and ensures stable long-term operation
- Polarity marked directly on the board — + and - connections are clearly identified, without risk of incorrect assembly
- Compact 20mm star format — easily integrates into small spaces and projects with multiple chips connected in series
- Chips can be connected in a chain directly from the factory — images of module strings confirm compatibility for multiple configurations
- Low 3W consumption with high luminous flux — superior efficiency compared to conventional sources of the same power
How it works and how to install it
The LED chip is directly soldered onto the star-type aluminum board, which absorbs and dissipates heat without requiring an additional external heatsink in low-power applications. Connection is made by soldering or screwing onto the pads marked with + and -, to a stable 3.2V-3.6V power supply with a driver or current-limiting resistor. For applications with multiple modules, the chips can be connected in series or parallel using the side pads of the star board.
Frequently Asked Questions
Do I need a separate driver for this 3W LED?
Yes, the chip requires a constant current source or an LED driver that provides 500-700mA at a voltage of 3.2V-3.6V; direct connection to a battery without current limitation can damage the diode.
Is the included aluminum heatsink sufficient, or is additional cooling needed?
For continuous operation at a nominal power of 3W, it is recommended to apply thermal paste and mount the star board on an external heatsink or a metal surface; for intermittent use or outdoors, the included support may be sufficient.
Can I connect multiple such chips together?
Yes, the star boards are designed for series or parallel interconnection via the side pads, as seen in the presented multi-module configurations; make sure the chosen driver supports the total voltage and current of the configuration.
