1W / 3W White High-Power LED on Aluminum Star PCB

White high-power LED emitter on a star PCB

This lighting component combines a white LED emitter with an aluminum star PCB. It is intended for suitable DIY light sources, torch repairs, small spotlights and electronics experiments where the driver and thermal arrangement are designed for the supplied LED.

The listing references 1W and 3W ratings without a confirmed selection or separate specifications. Confirm the exact supplied rating before choosing a driver. Do not assume that one LED is automatically suitable for both power levels.

Listed component details

• Emitter colour: white.
• Mounting: aluminum star PCB.
• Connections: positive and negative solder pads.
• Power designation: 1W / 3W in the listing; supplied version needs confirmation.
• Drive requirement: suitable current control matched to the actual LED.

Match the LED driver and cooling

Check the LED’s rated forward current and voltage before powering it. Those electrical values are not established here, so do not select a driver using a generic 1W or 3W assumption. A suitable constant-current LED driver is normally the starting point for this type of emitter.

The star PCB helps spread heat toward a suitable heatsink; it does not eliminate heat generation. Assess the required heatsink and thermal interface for the operating current and enclosure. Avoid running the emitter at full power without an appropriate thermal design.

Observe polarity when wiring, disconnect power before assembly and avoid looking directly into a bright emitter. Colour temperature, luminous output, beam angle and numerical PCB dimensions are not specified.

A driver, optical lens and additional heatsink are not established as included. Browse LED components at EPRO for other formats.

Frequently asked questions

Can I connect it directly to a 12V battery?

Not as an assumed direct connection. Use a suitable current-controlled driver matched to the actual LED.

Is the star PCB a complete heatsink?

Do not assume so. Additional heatsinking can be required depending on power and installation.

Will I receive a 1W or 3W LED?

Confirm the supplied version and quantity with EPRO before ordering.
