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.
