Intelligent lighting device having - several lights (L1...L24), wherein each light is equipped with a wireless communication device and by doing so the lights are coupled to one another, - wherein the lights (L1...L24) are provided with group addresses for defining one group (G1... G6) of lights (L1...L24) immediately adjacent to one another, - and wherein each of the lights (L1...L24) can be operated in at least three lighting modes: a first operating mode (off), a second operating mode (working level) and a third operating mode (base level), which lies between the first and second operating modes; - and wherein each light (L1...L24) is available for presence recognition via a sensor device, wherein, on detecting a person in the sensor region of the respective light, this is switched into the second operating mode (working level); - wherein each communication device of the other lights (L1...L24) located in the vicinity of this light (L1...L24) detects the switching of this light (L1...L24) into the second operating mode (working level); - and wherein each of the other lights (L1...L24) having the same group address as the light (L1...L24) switched on into the second operating mode (working level) is switched off because of the detection from the first operating mode (off) into a mode that is different to the first operation mode (off); characterised in that - the lighting device is configured as an interior space lighting device, - each of the lights (L1,..., L24) has a switching device on the light (L1,..., L24) that is to be manually activated and via which the respective light (L1...L24) is able to be switched into its first, second or third operating mode, - and wherein the other lights (L1... L24) having the same group address as the lights whose switching into the second operating mode (working level) has been detected, are switched from the first operating mode (off) into the third operating mode (base level), - and wherein the communication device of the lights (L1... L24) that are lit in the second operating mode (working level) communicates the lack of the presence recognition after a running time has finished to the other lights (L1... L24) with the same group address. - several lights (L1...L24), wherein each light is equipped with a wireless communication device and by doing so the lights are coupled to one another, - wherein the lights (L1...L24) are provided with group addresses for defining one group (G1...
