LED Bead Specifications for 1W and 3W LEDs

1 and 3 watt LED Technical and Optical Specifications

LED Beads

The LED Bead is the fundamental element of a high-power LED module. The Bead design is for mounting to a heat-conducting surface to draw away excess heat from the LED. See our complete assortment of LED Bead aluminum base plates, heatsinks, and accessories.

LED Beads are available in 1 and 3-watt models in assorted colors and specialty models for ultraviolet and infrared applications. Additional accessories such as lens assemblies are available to focus the output light depending on your requirements or high-power current drivers in various models.

The LED Bead is a cost-efficient option to pre-assembled LED modules, where you can solder the LED to an aluminum base plate of your choice. We carry a diverse selection of base plates holding from one to six individual LED Beads.

Identifying LED Bead Pins

LED Bead Connection Information

Each LED Bead has two connections for a single-color LED, the Anode (+) and Cathode (-).

To signify the differences in the connection leads, the Anode usually has a “+” stamped on the lead. The Cathode may have a “” stamped on the connection lead. Additionally, the Cathode may also have a polarization hole on the lead close to the body of the LED.

LED Bead Heat Sink Tab

LED Bead Heat Sink Tab

The bottom of the LED Bead contains a metal tab. designed to be placed onto a heat-transferring material (heatsink). The heatsink can range from STAR LED Carrier Board, to a Heatsink Platform or to a carrier board that holds several LEDs. Between the LED and the heatsink, ensure there is Thermal Heatsink Compound or Thermal Heatsink Adhesive allowing heat to transfer efficiently between the LED Bead and the heatsink material and is essential in the operation of a LED Bead.
