The UV rays react with coating, which produces the visible light. The electrons emitted from the coating is what makes the red, blue, green light.
WebThe Clowes Hydrogen Lamp Soon after the introduction of the safety lamp underground, miners noticed that its flame changed if there were gases in the atmosphere. In the late-nineteenth century, lamp makers began to develop dedicated gas-testing lamps, such as the Clowes Hydrogen lamp, that would give more sensitive readings of methane levels.
