Definitions
- the present invention relates to a luminaire with at least two light sensors, a lighting system with at least one such luminaire and a method for operating such a luminaire, in particular a method for detecting the ambient light of such a luminaire.
- Light sensors are used in buildings, in particular rooms, as well as in Lrei to adjust the brightness of a lamp with at least one light source.
- a light sensor is used in order to be able to set a brightness at one point in a room, such as a workstation, in accordance with a setpoint brightness of a workstation illuminated by a lamp.
- at least one light sensor must be arranged in the vicinity of the luminaire in such a way that the light sensor can detect or measure the ambient light of the luminaire and consequently the light at the workstation.
- the detection result or measurement result is then typically transmitted from the light sensor to the luminaire and used as an instantaneous value of the brightness at the workplace in order to set the brightness of the luminaire to a setpoint value.
- a lighting system comprising a light sensor and a lamp with at least one light source
- the light sensor can be damaged without special protective measures, for example due to vandalism. This could be avoided by arranging the light sensor in a suitable housing that offers protection against vandalism.
- this is associated with costs and increases the dimensions of a single light sensor.
- the light sensor can be damaged or even destroyed by penetrating luminosity, and light detection by the light sensor can be impaired or impossible due to contamination. This can also be avoided by arranging the light sensor in a suitable housing, but this again leads to the disadvantages of increased costs and enlarged dimensions of the light sensor.
- the tightness of the luminaire can also be impaired, especially if the detection results of the light sensor are transmitted by wire, since leaks can occur at the transition between a cable for wired transmission and the lamp housing. This can be avoided in that appropriate provisions are made for connecting the cable to the lamp housing, so that the tightness of the lamp is not impaired. However, this is again associated with corresponding effort and costs.
- One way of overcoming the above disadvantages would be to arrange the light sensor directly inside the housing of the luminaire.
- the light sensor would be protected against vandalism, dirt and luminosity through the housing of the light. Learner, the tightness of the luminaire could no longer be impaired by a cable as a wired transmission path from a light sensor arranged outside the housing to the luminaire housing.
- the disadvantage of this possibility is that a light sensor arranged within the lamp housing would not only detect the ambient light, but also the light that is emitted or emitted within the lamp housing by the at least one lamp of the lamp. As a result, the brightness of the light emitted by the luminaire could not be regulated on the basis of the detected instantaneous brightness of the ambient light with regard to a setpoint brightness.
- a luminaire is provided with a housing having a diffusing screen as a light-emitting surface, with at least one illuminant which is arranged inside the housing in such a way that it is set up to emit light through the diffusing screen to the outside of the housing, and with at least two Light sensors arranged within the housing and configured to detect light are provided.
- the at least two light sensors have different detection areas and are set up to detect light, the detection area of the first of the at least two light sensors being such that light emitted by the at least one illuminant and reflected on at least one wall of the housing interior is detected.
- the present invention proposes to arrange at least two light sensors with different detection areas inside the housing of a lamp (to be integrated into the lamp housing) in order to detect the light entering or entering the inside of the lamp housing through the diffuser from outside the housing or to be able to measure.
- at least one first light sensor of the at least two light sensors is set up to detect or measure light that is emitted by the at least one lamp of the lamp and is reflected on at least one wall of the interior of the lamp.
- the detection area of the at least one first light sensor is set in such a way that the first light sensor detects light emitted by the at least one illuminant and reflected on at least one wall of the housing interior, or that in the detection area of the first light sensor emitted by the at least one illuminant and on Light reflected from at least one wall of the interior of the housing is incident on the first light sensor.
- the at least one wall of the housing interior is in particular at least one side wall or side wall of the housing interior.
- the at least one first light sensor of the at least two light sensors is therefore set up in particular to detect scattered light inside the housing.
- the detection range of the at least one first light sensor is set in particular such that the first light sensor is scattered light Detected inside of the housing or that in the detection area of the first light sensor, scattered light falls on the first light sensor inside the housing.
- the luminaire is advantageous because the arrangement of the at least two light sensors inside the housing eliminates the disadvantages described above with regard to a light sensor arranged outside the luminaire. Learner can detect the least two light sensors inside the housing due to their different detection areas the light entering from outside the luminaire housing through the diffuser into the interior of the housing and consequently the ambient light of the luminaire.
- the luminaire according to the invention therefore enables the light emitted by the at least one illuminant of the luminaire to be set to a brightness to achieve a target brightness on the basis of the detected ambient light of the luminaire without the disadvantages described above occurring.
- diffuser can be used as a synonym for the term "diffuser”.
- detection area of a light sensor is understood to mean the area inside the housing within which the light sensor can detect light. I. E. a light sensor does not detect any light that is present outside the detection range of the light sensor or that falls outside the detection range on the light sensor.

In particular, the lighting means 4 and the light sensors S1 and S2 are arranged next to one another or in a row on the circuit board.
- the luminaire 1 has the diffusing screen 3 as a light-emitting surface, so that the light emitted by the lighting means 4 is emitted or radiated through the diffusing screen 3 to the outside of the housing 2.

- the at least one wall of the interior of the housing is in particular at least one side wall or side wall of the interior of the housing.

- the detection area B2 of the second light sensor S2 is set in such a way that the second light sensor S2 only detects light from the area of the lens 3 or that in the detection area B2 of the second light sensor S2 only light from the area of the lens 3 onto the second light sensor S2 falls.
- the detection area B2 of the second light sensor S2 is set such that in the detection area B2 of the second light sensor S2, light E r 2 emitted by the lighting means 4 and reflected on one or more walls of the interior of the housing does not hit the second light sensor
- the second light sensor S2 is specifically designed to only detect light E t entering the interior of the housing from outside the housing 2 through the diffusing screen 3 and light E ri emitted by the lighting means 4 and reflected on the diffusing screen 3. That is, the light falling on the second light sensor S2 in the detection area B2 of the second light sensor S2 is composed of light E t which enters the interior of the housing from outside the housing 2 through the diffuser 3; and light E ri emitted by the lighting means 4 and reflected on the diffusing screen 3.
- the two light sensors S1 and S2 are set up to display their detection results, i. H. To provide or supply detection values to a processing device which can then determine the ambient light of the lamp 1 on the basis of these detection values detected by the two light sensors S1 and S2.

In other words, the processing device 6 is set up to process the detection values detected by the two light sensors S1 and S2 in order to determine the ambient light of the lamp 1.
- the processing device 6 is set up to determine the light emitted by the lighting means 4 on the basis of detection values which the first light sensor S1 detects.
