The LED Bead is the fundamental element of a high-power LED module. The Bead is designed to be mounted 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.
They are extremely bright, many times more so than a 5mm LED and generally produce a wide angle of light disbursement which can be narrowed through the use of an external lense.
Model: BEAD-3W-R-120-01 - Red Color Frequency: 620-625nm (Red) Luminous Intensity: 80-90 lumen Viewing Angle: 120° Radiation Pattern: Lambertian Forward Voltage: 2.4v - 2.7v Typical Voltage: 2.5v Typical Forward Current: 700mA
Model: BEAD-3W-R-120-02 - Deep Red Color Frequency: 660nm (Deep Red) Luminous Intensity: 40-50 lumen Viewing Angle: 120° Radiation Pattern: Lambertian Forward Voltage: 2.2v - 2.6v Typical Voltage: 2.3v Typical Forward Current: 700mA
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.
The bottom of the LED Bead contains a metal tab. This tab is 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 a Thermal Heatsink Compound or Thermal Heatsink Adhesive. The compound or adhesive will allow heat to transfer efficiently between the LED Bead and the heatsink material and is essential in the operation of a LED Bead.
