Abstract

This article deals with a material saving technical solution for luminaires with tri-phosphorus fluorescent lamps, operated in low environmental temperatures. The resulting loss of luminous flux of the lamps at falling temperatures has to be improved, particular value is attached to a technically sound, constructive solution with an ideal cost-performance ratio. In the article is shown how to design a particularly low-priced and cost-efficient luminaire, and nevertheless at least still strongly reduce the undesirable loss of the luminous flux, in order to obtain an alternative solution for general outdoor lighting and for lighting in open buildings. A solution to this problem is presented. The problem has been solved by shaping the protecting tube on both ends over the adapter bushings, which function as heat accumulator, and which hold the heat accumulation tube Ill. 3, bibl. 6 (in English; summaries in Lithuanian, English, Russian).
