Technical Drawing of an Incandescent Light Bulb DesignDescription
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.Context
This drawing is significant in the history of electric lighting and invention. Lewis Howard Latimer played a pivotal role in improving and patenting the carbon filament, which made incandescent bulbs more durable and cost-effective. His contributions to Edison’s lighting system helped bring electric lighting to homes and businesses on a large scale. The image illustrates technical refinements made to the light bulb, ensuring longer-lasting filaments and enhanced electrical connections.Collection
