Dual-function lighting device

A heat sink is provided having at least one receiving section configured to be thermally coupled to at least one lighting module. The heat sink includes at least two connecting sections on opposite sides of the at least one receiving section. Each of the at least two connection sections includes at least one reference pin at least partially protruding from a first surface of the at least one connection section and at least one alignment recess protruding into the first surface of the at least one connection section, the heat sink is configured to be thermally coupled to another heat sink via the at least two connection sections. 提供具有至少一个接收区段的散热器，所述至少一个接收区段被配置成热耦合到至少一个照明模块。该散热器包括在该至少一个接收区段的相对侧上的至少两个连接区段。所述至少两个连接区段中的每一个包括至少部分地从所述至少一个连接区段的第一表面突出的至少一个参考销和突出到所述至少一个连接区段的所述第一表面中的至少一个对准凹部，使得所述散热器被配置成经由所述至少两个连接区段热耦合到另一散热器。
