Luminaire with antenna array for determining the direction and / or determining the position by means of an angle of incidence and / or angle of radiation measuring method

摘要

Luminaire (1) comprising - a housing (2) with a light-emitting surface (8), - a circuit board (3) arranged within the housing for the electrical supply of at least one illuminant (5), for example at least one light-emitting diode, the at least one illuminant on one of the light-emitting surface (8) facing surface (3a) of the circuit board (3) can be arranged, and an antenna array (6) with at least two antennas (6a) which is arranged inside the housing (2) in the region of the light-emitting surface (8) - wireless signals sent by an external device through the light-emitting surface (8) for a determination based on an angle of incidence measurement method of the direction of the external device in relation to the lamp (1) and / or a determination based on a radiation angle measurement method the position of the lamp (1) to receive and / or wireless signals through the light-emitting surface (8) to an external device for an angle of incidence To send a determination of the direction of the luminaire (1) in relation to the external device based on the measurement method and / or a determination of the position of the external device based on the beam angle measurement method.
