| Abstract |
The minimum illumination of 5 lx recommended in 1949 by the ILO in its Model Code of Safety Regulations for Industrial Establishments is considered inadequate in many countries. Fluorescent lamps are therefore required in such installations, and for this reason semiconductor inverters and series equipment have been developed for fluorescent lamps; circuit diagrams are provided to show their operation. Switching from mains to battery operation occurs virtually without interruption. Another piece of equipment makes it possible to switch in the emergency-operation circuit in the event of a starter proving defective. Advice is given on suitable batteries. |
