ABSTRACT:
The lighting structure disclosed is particularly useful for operational areas where the reflection is poor and which are subject to the risk of explosion and fire damp. The novel lighting structure comprises a casing containing power supply means and a fluorescent tube. The power supply means is a constant current transformer with power factor compensation and a rubber-like mass encases the transformer and tube connector terminals to conceal all live electrical parts except for the light emitting portion of the tube.
