Part 3/7:
A flicker flame lamp is a clever adaptation of traditional neon indicator lamps. These lamps consist of a glass envelope filled with gases, typically neon or argon, with electrodes positioned inside. When a high voltage is applied to the electrodes, a visible glow discharge occurs, creating light. The unique flickering motion arises from the engineering of the electrodes, designed to replicate a flame's dynamic appearance, ultimately transforming how we perceive this artificial illumination.
