DGS70/127N type explosion-proof and waterproof high-pressure sodium lamp for coal mines
The above two types are pioneering in China. This lamp adopts a new light source dual tube core, with one tube working and the other tube in a "waiting" state. If one tube core reaches the end of its life or is damaged due to a fault, the other tube core will automatically light up. In case of an instant power outage, it will be immediately powered on. The 'waiting' chip immediately lights up, ensuring long-term continuous lighting and ensuring production safety.
