Zusammenfassung:	A lighting device (1) is disclosed. The lighting device (1) comprises: a communication unit (10) for wireless communication between the lighting device (1) and an external device; a solid-state lighting element (3) electrically connected to the communication unit (10); a heat sink (5) in thermal contact with the solid-state lighting element (3), the heat sink (5) having a slot (5a) adapted to act as a slot antenna; and a feed antenna (11) electrically connected to the communication unit (10), the feed antenna (11) having at least one end tip arranged at the slot (5 a) so as to enable the feed antenna (11) and the slot (5a) to communicate by proximity coupling.
