The some 2000-year old Pécs is rich of historical and architectural monuments. Pécs is the third largest city in Hungary, with approximately 200.000 inhabitants. In this way to develop the public lighting of streets and roads always meant serious task for the experts. The installation of the public lighting operating from electric network in Pécs began in 1924. Since that time the development was speedy and significant. The evolution was substantial especially from the end of 50's, during the application of the fluorescent lamps in public lighting. This type of lamp replaced the tungsten filament lamps on the public lighting networks, which were applied generally and uniformly until that time. The fluorescent lamp brought significant development into the illuminating engineering, since its light utilisation is better and has longer lifetime then the normal lamps. The next great step was in the development the substantial and rapid spreading and application of the mercury-vapour lamps in the public lighting in the 60's. Nowadays we can see the greatest development, which is the most significant in the history of the evolution of the public lighting. It is the general application of the energy efficient high-pressure sodium lamp in the public lighting. The appearance of this type of lamp began in Hungary and also in Pécs, at the end of the 70's and at the beginning of the 80's... Ver documento.. SUMMARY.
