Light module comprising at least two semiconductor light source chains and methods for controlling and / or regulating the supply energy of the at least two semiconductor light source chains

摘要

The invention relates to a light module (6) comprising at least two semiconductor light source chains (9), of which at least two each have at least one semiconductor light source (8), a control device (15) for supplying the semiconductor light source chains (9) with a supply energy (U_15 ) and means for controlling and / or regulating the supply energy of the individual semiconductor light source chains (9). In order to enable the simplest, most cost-effective and as flexible as possible operation of a plurality of semiconductor light source chains (9) on an output channel of a control device (15), it is proposed that the means (17; 16; 16a, 16b; or regulation of the supply energy comprise at least one switching element (16; 16a, 16b; 18) which divides the supply energy (U_15) during predeterminable time segments onto the individual semiconductor light source chains (9).
