In 1862, the French inventor Alphonse Dumas developed a lamp for miners, which became known as the Ruhmkorff Lamp. The light source was a gas – filled glass cylinder in which an electric spark was generated. With its chemical battery, the Ruhmkorff Lamp was the first portable electric lamp, and so a fo rerunner of modern – day torches.
Although the lamp was too heavy to succeed on the market, it did inspire the author Jules Verne in writing his famous adventure stories, so instead of providing light for miners in tunnels, they were illuminating dark caves and gorges in novels like the classic “Journey to the Centre of the Earth”.
Now, Louis and I have taken these old lamps and given them a technological makeover for the present day. The design now consists of a charging station with an orientation lamp and a removable tube with an LED illuminatingthe transparent plastic rod.
