System och metod för skyltbelysning samt modulenhet avsedd att användas i samband med ett system för skyltbelysning

摘要

The present invention relates to a system for illuminating a sign, comprising a housing (1) with an outer contour of a symbol such as a number or a letter, for example; two or more lamps (2) arranged in the housing (1); a source (3) of mains voltage; a lead (13) that connects the mains voltage source (3) to the lamps (2) and a transformer (4) arranged betweeen the mains voltage source (3) and the lamps. The lamps (2) consist of subminiature lampe (2) to a voltage that is below the voltage from the mains voltage source (3), so that the lamps (2) are supplied with a voltage that is below the voltage from the mains voltage source (3). The invention also relates to a method for illuminating a sign, in which method a mains voltage is transformed down and supplied to incandescent lamps placed in a housing. The invention also relates to a modular unit intended for use in the system according to the invention, which modular unit (5) comprises subminiature lamps (2).
