Historical Electric Arc Lamp Diagram - Technical Schematic & Component Breakdown #3751040 (License: Personal Use)

This technical drawing depicts a cross-section of an early electric arc lamp, featuring two U-shaped carbon electrodes (labeled 'a') housed within a refractory ceramic or metal casing (D). Cooling coils (B) wrap around the lower section to manage thermal load, while insulating supports (F) and a central base (C) secure the assembly. The design reflects late-19th-century innovations in high-intensity lighting before incandescent dominance.

Used in historical engineering archives, museum exhibits, and educational resources on the evolution of electric lighting; targets researchers, students, and enthusiasts seeking primary-source schematics of pre-modern illumination technology.
