The device includes a control for controlling at least one LED high bay; a presence sensor which emits a presence signal to the control when the presence sensor detects a person or object, such as a forklift truck driver or a forklift truck; and includes an activity sensor which emits an activity signal to the control when an activity, such as for instance a lifting movement of a forklift truck, is detected and the control, when the presence signal and the activity signal are received simultaneously, generates a control signal for the control of the intensity level of the at least one LED high bay. ## Claims ### Claim 1 A device for interactive and location-dependent control of lighting properties, such as intensity or colour temperature, of at least one LED high bay with a downward directed light beam, in for instance a warehouse or industrial premises, wherein the device comprises: a control for controlling at least one LED high bay; a presence sensor which emits a presence signal to the control when the presence sensor detects a person or object, such as a forklift truck driver or a forklift truck; and an activity sensor which emits an activity signal to the control when an activity, such as for instance a lifting movement of a forklift truck, is detected and wherein the control, when the presence signal and the activity signal are received simultaneously, generates a control signal for the control of the intensity level of the at least one LED high bay. ### Claim 2 (depends on 1) The device according to claim 1, wherein the activity sensor comprises face recognition, wherein the face recognition comprises a camera, which camera is configured to record an image within a downward directed light beam, wherein the activity sensor emits an activity signal to the control upon recognition of a face in the image. ### Claim 3 (depends on 1) The device according to claim 1, wherein the activity sensor comprises the presence sensor and also emits a presence signal to the control when an activity is detected. ### Claim 4 (depends on 1) The device according to claim 1, wherein the presence sensor comprises a passive infrared sensor (PIR sensor). ### Claim 5 (depends on 1) A combination of a device according to claim 1 one LED high bay with a downward directed light beam, wherein the at least one LED high bay receives a control signal from the control in order to control the intensity level of the light beam. ### Claim 6 (depends on 5) The combination according to claim 5, wherein the at least one LED high bay sets the intensity of the light beam from a first intensity level to a second, lower intensity level when the control signal is received, and sets the first intensity level when the first control signal is absent. ### Claim 7 (depends on 6) The combination according to claim 6, wherein the second intensity level is 1-50% of the first intensity level, preferably 5-20%, preferably 20%. ### Claim 8 (depends on 5) The combination according to claim 5, wherein the at least one LED high bay also sets the colour temperature of the light beam, this in addition to the intensity level, from a first colour temperature to a second, lower colour temperature when the control signal is received, and sets the first colour temperature when the first control signal is absent. ### Claim 9 (depends on 8) The combination according to claim 8, wherein the second colour temperature is 1500-4000K lower than the first colour temperature, preferably 2500-3500K lower. ### Claim 10 (depends on 5) The combination according to claim 5, wherein the combination further comprises a vehicle, which vehicle comprises a liftable platform and a platform control, such as a forklift truck or boom lift, wherein the activity sensor is arranged on the vehicle and wherein the platform control activates the activity sensor. ### Claim 11 (depends on 2) The device according to claim 2, wherein the activity sensor comprises the presence sensor and also emits a presence signal to the control when an activity is detected. ### Claim 12 (depends on 2) The device according to claim 2, wherein the presence sensor comprises a passive infrared sensor (PIR sensor). ### Claim 13 (depends on 3) The device according to claim 3, wherein the presence sensor comprises a passive infrared sensor (PIR sensor). ### Claim 14 (depends on 11) The device according to claim 11, wherein the presence sensor comprises a passive infrared sensor (PIR sensor). ### Claim 15 (depends on 6) The combination according to claim 6, wherein the at least one LED high bay also sets the colour temperature of the light beam, this in addition to the intensity level, from a first colour temperature to a second, lower colour temperature when the control signal is received, and sets the first colour temperature when the first control signal is absent. ### Claim 16 (depends on 7) The combination according to claim 7, wherein the at least one LED high bay also sets the colour temperature of the light beam, this in addition to the intensity level, from a first colour temperature to a second, lower colour temperature when the control signal is received, and sets the first colour temperature when the first control signal is absent. ### Claim 17 (depends on 6) The combination according to claim 6, wherein the combination further comprises a vehicle, which vehicle comprises a liftable platform and a platform control, such as a forklift truck or boom lift, wherein the activity sensor is arranged on the vehicle and wherein the platform control activates the activity sensor. ### Claim 18 (depends on 7) The combination according to claim 7, wherein the combination further comprises a vehicle, which vehicle comprises a liftable platform and a platform control, such as a forklift truck or boom lift, wherein the activity sensor is arranged on the vehicle and wherein the platform control activates the activity sensor. ### Claim 19 (depends on 8) The combination according to claim 8, wherein the combination further comprises a vehicle, which vehicle comprises a liftable platform and a platform control, such as a forklift truck or boom lift, wherein the activity sensor is arranged on the vehicle and wherein the platform control activates the activity sensor. ### Claim 20 (depends on 9) The combination according to claim 9, wherein the combination further comprises a vehicle, which vehicle comprises a liftable platform and a platform control, such as a forklift truck or boom lift, wherein the activity sensor is arranged on the vehicle and wherein the platform control activates the activity sensor.
