32mm 3-LED Aluminum Base Plate PCB

32mm - 1.25-inch Board Holds 3 LED Beads

32mm 1.25-inch 3-LED Aluminum Base Plate PCB

This display board accommodates three LED Beads on a 32mm (1.25-inch) diameter aluminum PCB. Useful in applications where a LED spotlight is required, such as for IR (Infrared), UV, or even standard color LEDs.

The three LEDs on the board are all connected in Series.

Each base plate has an aluminum backing and is designed to accommodate standard 2-pin 1 watt, 3 watt, or 5 watt LED Beads.

The aluminum base plate pulls heat away from the LED Beads. The plate should be attached to a larger heatsink to provide full cooling of the LEDs through the pre-drilled mounting holes. The board alone does not provide sufficient heat sink capability to handle the full power of the LED.

When soldering the LED to the board, it is critical to use thermal paste between the LED's body and the center board pad. The thermal paste ensures efficient heat transfer from the LED. If using hot air or a hot plate to reflow the solder to mount the LED, it is possible to use solder paste under the LED to solder the LED to the center pad rather than using thermal paste. The solder provides ideal thermal coupling.

Since the board is constructed of aluminum, it is a small heat sink, be sure to use a good quality soldering iron with at least a medium-size tip for soldering the connections.

Note: This item is for the bare PCB only. You must supply your own LEDs.
