Abstract (en)
[origin: WO0212787A1] An explosion proof lighting device which is suitable for lighting an area which is at risk of explosion, belonging to zone zero, comprising a housing (1), a light source (3) which is situated in the housing, a light guide (4), one end of which is connected to the housing, a light head (5), which is arranged at the other end of the light guide, and a power supply (6) to the housing in order to provide at least the light source with energy. The housing is provided with an air feed line (7) for feeding air, while the device is operating, to the housing from an air source which is at a distance from the housing, in order to maintain an excess pressure in the housing with respect to the environment. The housing is also provided with a pressure-monitoring system, which ensures that the device is switched off safely if the excess pressure in the housing becomes too low or too high.
