DescriptionIn 1881 Lewis Latimer proposed a new lamp equipped with several carbons and an easy method for replacing them. His work “baking” carbonized filaments made of wood and paper taught him how fragile they were, leading him to conceive this new form for an electric lamp. He never patented it. This is a detailed technical drawing of an incandescent light bulb, showcasing the inner workings of its filament and electrical components. The diagram includes precise measurements, spring-loaded terminals, and structural elements that contribute to the bulb's functionality. The illustration appears to be a schematic representation of an early electric light bulb, likely developed during the late 19th century.
