The present invention relates to a luminaire (), comprising a housing () having a diffusion panel () as light emission surface, comprising at least one illuminant () which is arranged within the housing () such that it is set up to emit light through the diffusion panel () to the area outside of the housing (), and comprising at least two light sensors (S, S) arranged within the housing (), the light sensors being set up to detect light. The at least two light sensors (S, S) have different detection regions (B, B) within the housing () and are set up to detect light (E) which enters through the diffusion panel () into the housing interior from the area outside of the housing (), wherein, on account of the different detection regions (B, B), one of the at least two light sensors (S, S) detects light (E) that was emitted by the at least one illuminant () and reflected from at least one wall of the housing interior. The invention further relates to a lighting system having at least one such luminaire and to a method for detecting the ambient light of such a luminaire.

The invention relates to a device for operating LEDs, comprising a driver module and an LED module (), which is controlled by the driver module () and has at least one LED. The LED module () is fed a current by the driver module () via a first connection (), and a second connection () is present, preferably as a ground connection (GND). The device is characterized in that the LED module () is connected to the driver module () by means of a third connection (), which is designed as a data channel, a voltage fed by the driver module () being applied to the data channel.

Device for operating LEDs

The invention relates to a method for operating LEDs (), comprising a driver module () and an LED module () having at least one LED (), which LED module () is controlled by the driver module (), wherein the driver module () has a first connection (), which is designed to feed the LED module () with a current, and has a second connection () is present as earth connection (GND), wherein the LED module () is fed with a current by the driver module () via a first connection () and a second connection () is present as earth connection (GND), characterized in that the driver module () temporarily lowers the voltage at the first connection () and monitors the voltage at the first connection () and is designed to evaluate a change in the voltage at said connection as a transfer of information from the LED module ().
