The flavor system comprises menthol, at least one other secondary coolant and selected flavor chemicals that together provide a stable flavor profile and a high impact refreshing taste and sensation. In the formula, \u201cR1,\u201d \u201cR2,\u201d and \u201cR3\u201d independently represent an alkyl group having a carbon number of 1 to 3, \u201cR4\u201d and \u201cR5\u201d independently represent hydrogen atom or an alkyl group having a carbon number of 1 to 3, and \u201cX\u2212\u201d represents a counterpart anion. Furthermore, a method for producing a light-emitting diode arrangement is specified, wherein the coding of a coding resistor is carried out depending on a determined characteristic of the light-emitting diode. A processor is coupled to the receivers to accurately determine the location of the lighting strike.
