Base/End Cap: Dielectric Strength ≥ 4kV

Component Specifications

Definition

The Base/End Cap is a critical structural component in UV-C germicidal lamp systems that serves dual functions: providing secure mechanical mounting and positioning for the lamp tube while ensuring proper electrical insulation and connection integrity. It typically interfaces with the lamp holder or fixture housing and may incorporate features for heat dissipation, moisture resistance, and UV radiation containment.

Working Principle

The component functions by providing a stable mechanical interface between the UV-C lamp tube and the fixture housing, ensuring proper alignment and secure mounting. It incorporates insulating materials to prevent electrical leakage and may include reflective surfaces to optimize UV radiation direction. The design accommodates thermal expansion of the lamp during operation while maintaining structural integrity.

Materials

High-temperature resistant thermoplastics (PBT, PPS, or ceramic-filled polymers) with UL94 V-0 flammability rating, or ceramic materials for high-power applications. Electrical contacts typically use nickel-plated brass or stainless steel.
