| 摘要 |
The invention relates to an illumination device (1) comprising a heat sink (5) to which at least one light source (8) is at least indirectly attached, wherein the heat sink (5) is displaceably mounted in a mounting element (4) such that the heat sink (5) is more difficult to displace in a powered state of the light source (8) than in a non-powered state of the light source (8). The method is designed to direct a light bundle emitted by an illumination device (1), wherein the illumination device (1) comprises a heat sink (5) to which at least one light source (8) is at least indirectly attached, said heat sink being displaceably mounted in a mounting element (4), wherein whenever the light source (8) is powered, the heat sink (5) is pressed harder against the mounting element (4) than in a non-powered state of the light source (8). |
