| description | ||||||||||||||||||||||
| Due to its special construction
an ignition of hazardous atmosphreres inside and outside the lamp
are avoided by several means. At first the air flows into the lamp
housing and generates an overpressure before it flows into the generator
housing. housing to drive the turbine wheel of the AC-generator to
induce the voltage for the bulb. 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. Pressure-fluctuations of the air are compensated by the air regulating system inside the lamp. The lamp-housing is made of brass. |
