Ok so here in the figure what you see is actually a typical safety lamp.

It was made in 1815 because when the miners used to dig deep down in the mine, there was too much dark and taking a candle would be more dangerous because methane was present in the mines and you should know that methane catches fire easily, so he made this device so that not much heat is given out and it could help the miners.
