Abstract: Method for production of conducting element, which conducting element consists at least of an elongated electricity conductive, in which several electric components (2), bringing out the lighting operation or like according to the use of the conducting element, are being attached to one after another in the longitudinal direction (s), whereafter the said entirety is being surrounded by a casing part (3) protecting the same. The conducting element is being manufactured from an essentially flat conductor part (1; 1′), such as a band, a stripe or a like, into which there has been attached electric components (2′), such as probes, LEDs, resistors and/or the like by arranging the same, preferably throughout built-in when viewed in a cross section with a casing material (3′) forming the said casing part (3), by exploiting a continuous manufacturing process, such as extrusion or like. The invention relases to a conducting element to be manufactured by the method, also.
