Illuminating device, imaging device, and method for operating same

Abstract

The invention relates to an illuminating device (102; 202; 302; 402; 502; 602; 702; 802) comprising: at least one heat sink (104; 204; 304;504; 604; 704; 804); at least one first lighting element (106; 206; 406; 706); at least one first cooling body section (108; 208; 308; 408; 508; 608) which is thermally coupled to the first lighting element (106; 206;406;706) and which is designed to absorb exhaust heat of the first lighting element (106); at least one first exhaust heat path (110; 210; 310) which thermally connects the first cooling body section (108; 208; 308; 408; 508; 608) to the heat sink (104; 204; 304;504; 604; 704; 804) such that exhaust heat of the first lighting element (106; 206; 406; 706) can be dissipated via the first exhaust heat path (110; 210; 310); at least one second lighting element (112; 212; 412; 712); at least one second cooling body section (114; 214; 314; 414) which is thermally coupled to the second lighting element (112; 212; 412; 712) and which is designed to absorb exhaust heat of the second lighting element (112; 212; 412; 712); at least one second exhaust heat path (116; 216; 316) which thermally connects the second cooling body section (114; 214; 314; 414) to the heat sink (104; 204; 304; 504; 604; 704; 804) such that exhaust heat of the second lighting element (112; 212; 412; 712) can be dissipated via the second exhaust heat path (116; 216; 316); and at least one adjusting element (118; 218; 318; 418) which is arranged between the first cooling body section (108; 208; 308; 408; 508; 608) and the second cooling body section (114; 214; 314; 414) and which is designed to adjust the heat flow from the first cooling body section (108; 208; 308; 408; 508; 608) to the second cooling body section (114; 214; 314; 414). The invention additionally relates to an imaging device (10) with an illuminating device (102; 202; 302; 402; 502; 602; 702; 802).
