Base/Connector: Current Capacity 0.1-2A

Component Specifications

Definition

A critical electromechanical interface component in LED bulb assemblies that establishes secure electrical contact between the bulb's internal circuitry and external power sources while providing structural stability and heat dissipation capabilities. It typically incorporates conductive pins, insulating housing, and mounting features designed for specific socket types.

Working Principle

The base/connector functions as an electromechanical interface by providing conductive pathways for electrical current flow from the power source to the LED driver circuit while maintaining physical alignment and thermal management through its structural design. It ensures proper polarity, contact pressure, and insulation to prevent short circuits.

Materials

Typically composed of brass or nickel-plated steel for conductive elements, ceramic or high-temperature thermoplastics (PBT, PPS) for insulating housing, with optional phosphor bronze spring contacts. Materials must withstand temperatures up to 150°C and provide corrosion resistance.
