Air Drive Lamp
An air drive lamp refers to a type of lighting fixture that utilizes compressed air to power its operation. These lamps are designed to be energy-efficient and durable, making them suitable for various applications where reliable lighting is essential. The compressed air drives the internal mechanisms of the lamp, such as the light source and any movable parts, providing a steady and consistent light output. Air Drive Lamps are often used in ship building, industrial settings, outdoor environments, and areas where electrical power may be limited or unavailable, offering a reliable lighting solution with minimal maintenance requirements.

Working principle
Due to its special construction an ignition of hazardous atmospheres inside and outside the lamp are avoided by several solutions. At first the air flows into the lamp housing and generates an over pressure before it flows into the generator housing. If the lamp housing or the protection glass is damaged, the air flows outside first. The generator stops immediately and cannot induce any voltage for the bulb. The exhausting air prevents a penetration of explosive gases inside the lamp and can cool the spiral of a broken bulb, too.
