Referring to fig. 1, fig. 1 is a flowchart illustrating an illuminance control method according to an embodiment of the present disclosure.
The method is applied to an illumination control system comprising a plurality of lighting units, as shown in fig. 1, and comprises:
step S11, acquiring a first acquisition illumination of a first position and/or a second acquisition illumination of a second position of the target area, wherein the first position is within a preset range of a working horizontal plane, and the second position is within a preset range of a vertical plane of eyes of a user;

In one possible embodiment, the lighting unit may include any one or more of an LCD (Liquid Crystal Display), an LED (Light Emitting Diode), a Mini LED (Mini Light Emitting Diode), a Micro LED (Micro Light Emitting Diode), and an OLED (Organic Light-Emitting Diode).
In a possible implementation manner, the second target illuminance according to the embodiment of the present disclosure may be obtained according to an Equivalent blackout pixel illuminance (EML), so as to implement adjustment of the illuminance of each lighting unit of the lighting system based on the health requirement.
Referring to fig. 2, fig. 2 shows a schematic diagram of sensitivity curves of a human visual system and a rhythm stimulation system according to an embodiment of the present disclosure.
In one example, as shown in FIG. 2, the demand for a visual task is measured by luminance, while the health demand for a rhythmic stimulus is measured by the equivalent melanopsin luminance. The disclosed embodiments use the sensitivity curve and the spectral distribution at the human eye to derive a conversion factor (R) between the equivalent blackout luminance (EML) and the luminance (L), i.e., EML ═ R × L. Generally, for office scenes, the vision task requires a desktop illumination of 300lux, and the rhythm stimulation requires a human eye to reach 200EML in a preset time period (such as a 9: 00-13: 00 time period), which can be used as a default value of the second target illumination in healthy lighting.

Of course, the above descriptions of the installation manners of the illuminance sensor, the lighting device, and the like are exemplary and should not be considered as limiting the embodiments of the present disclosure, and in other embodiments, the illuminance sensor may have other installation manners, such as being installed on a ceiling, and also being capable of directly measuring natural lighting toward a lighting window. For ceiling and installation forms facing the daylight window, the illuminance provided by the daylight can be calculated by the related art according to room parameters.
In a possible embodiment, the lighting parameters may include electrical parameters (such as current, voltage, etc.) for driving the lighting unit to emit light, or lighting levels or gears of the lighting unit, at which the lighting unit has different light-emitting luminances.
The methods of the embodiments of the present disclosure may be performed by processing components, including but not limited to a single processor, or discrete components, or a combination of a processor and discrete components.

Within the processor, the executable instructions may be executed by hardware circuits such as logic gates, switches, Application Specific Integrated Circuits (ASICs), programmable logic controllers, and embedded microcontrollers.
Referring to fig. 4, fig. 4 is a flowchart illustrating an illuminance control method according to an embodiment of the disclosure.
In one possible embodiment, as shown in fig. 4, the method may further include:
in step S14, the target lighting parameters of each lighting unit are determined with the minimum sum of the lighting parameters of each lighting unit as a constraint condition.
According to the embodiment of the disclosure, when the target illumination parameters of each illumination unit are determined according to the first target illumination and the first natural illumination at the first position and/or the second target illumination and the second natural illumination at the second position, the target illumination parameters of each illumination unit are determined by taking the minimum sum of the illumination parameters of each illumination unit as a constraint condition, so that energy can be further saved, the visual task needs of people can be guaranteed at the desktop illumination with the lowest energy consumption, the spectral distribution and the illumination of the illumination at the eyes of the people can be controlled to achieve sufficient rhythm stimulation, and the health needs can be met.
In a possible embodiment, the step S12 determining a first natural light illuminance according to a first light illuminance of a plurality of lighting units at the first position and the first collected illuminance may include:
determining the first light illumination according to the current illumination parameters and first preset parameters of each illumination unit, wherein each first preset parameter is related to the illumination parameter of the corresponding illumination unit and the light illumination of the corresponding illumination unit at the first position;
and determining the first natural illumination according to the difference between the first collection illumination and the first lamp illumination.
In a possible embodiment, the determining a second natural light illumination according to a second light illumination of the plurality of lighting units at the second position and the second collected illumination includes:
determining the second light illumination according to the current lighting parameters and second preset parameters of each lighting unit, wherein each second preset parameter is related to the lighting parameter of the corresponding lighting unit and the light illumination of the corresponding lighting unit at the second position;
and determining the second natural illumination according to the difference between the second collection illumination and the second lamp illumination.
In one example, the illumination provided by lighting unit i at the desktop and human eyes of target area (e.g., workstation) j and the lighting parameters (e.g., gear) D of the lighting unit at the current timei,τIn direct proportion, the first predetermined parameter and the second predetermined parameter are kij,z(Table illuminance-coefficient of gear position) and kij,y(human eye illumination-coefficient of gear), wherein i and j are integers. The sizes of the first preset parameter and the second preset parameter in the embodiments of the present disclosure are not limited, and those skilled in the art may set the first preset parameter and the second preset parameter according to actual situations, for example, the first preset parameter and the second preset parameter may be obtained through analog calculation or actual measurement.
In one example, the illumination intensity provided by lighting unit i at the first position at station j may be the product of the first preset parameter and the current lighting parameter, i.e. kij,z*Di,τThe illumination provided by the lighting unit i at the second position at the station j can be the product of the second preset parameter and the current lighting parameter, i.e. kij,y*Di,τWherein τ represents time, Di,τRepresenting the lighting parameter, D, of the lighting unit i at the current instant τi,τ+1The illumination parameters of the illumination unit i at the time τ +1 are represented, and the illumination parameters at the next time can be obtained by the illumination control method of the embodiment of the disclosure, so that the requirement of normal working illumination is met, and the requirements of health management and energy conservation are met.
In one example, at each workstation j, a first light illumination L 'provided by the plurality of lighting units at a first location'jz,τCan be shown as equation 1:
wherein m represents the total number of lighting units.
In one example, at each workstation j, a second light illumination L 'provided by the plurality of lighting units at the second location'jy,τCan be shown as equation 2:
in one example, the first and second collected illuminances obtained in step S11 can be respectively denoted as Ljz,τAnd Ljy,τ. The first natural light illumination provided by natural light at the first position of the station (j) at the current moment tau is marked as Sjz,τAnd recording a second natural light illumination provided by the natural light at the second position of the station (j) at the current moment tau as Sjy,τThe natural light providing illumination at station j may be the detected total illumination minus the illumination provided by the lighting unit, i.e.,
in one example, the first natural illuminance may be determined according to a difference between the first collected illuminance and the first lamp illuminance, as shown in formula 3:
Sjz,τ=Ljz,τ-L′jz,τequation 3
In one example, the second natural light illuminance may be determined according to a difference between the second collected illuminance and the second lamp illuminance, as shown in equation 4:
Sjy,τ=Ljy,τ-L′jy,τequation 4
In one example, the illumination (L) and the equivalent blackcurrant illumination (EML) are both additive, i.e., for multiple light sources, the illumination may be determined by equation 5 and the equivalent blackcurrant illumination may be determined by equation 6:
L=∑Liequation 5
EML=∑(Ri*Li) Equation 6
In one example, since the spectral distributions of the natural light and the lamp light may be considered to be constant, the conversion coefficient (Rs) of the natural light and the conversion coefficient (Ri) of the lamp light may be set in advance according to the spectral characteristics. For the case of the light spectrum change, the conversion coefficient Ri of the spectrum after the change can be calculated according to the sensitivity curve shown in fig. 2, and certainly, the specific determination manner of the conversion coefficient and the specific size of the conversion coefficient are not limited in the embodiment of the present disclosure, and a person skilled in the art can determine the conversion coefficient Ri according to needs and actual situations.

the second condition includes: and the sum of the lamp illumination at the first position and the first natural illumination of each lighting unit under the action of each target lighting parameter is greater than or equal to the first target illumination, and the sum of the lamp illumination at the second position and the second natural illumination of each lighting unit under the action of each target lighting parameter is greater than or equal to the second target illumination.
In one example, the first condition may be as shown in equation 7, and the second condition may be as shown in equations 7 and 8.
∑(kij,z*Di,τ+1)+Sjz,τ≥LjEquation 7
∑(Ri*kij,y*Di,τ+1)+Rs*Sjz,τ≥EMLjEquation 8
For different time periods, the disclosed embodiments may determine the target lighting parameters of each lighting unit according to the above methods, respectively, for example, outside a preset time period, the illumination influence at the human eye may not be considered, so the target lighting parameters of each lighting unit are determined according to the first condition, while for the preset time period, the illumination influence at the human eye needs to be considered at the same time, so the disclosed embodiments determine the target lighting parameters of each lighting unit according to the second condition in this case.
In one possible implementation, the disclosed embodiments may solve equation 7 or equation 7 and equation 8 to obtain the target illumination parameters for multiple groups of illumination units, in which case the disclosed embodiments may use the minimum sum of the illumination parameters for each illumination unit as the constraint (Min ∑ D) for the minimum sum of the illumination parameters for each illumination uniti,τ+1) Determining the target lighting parameters of each lighting unit, that is, solving formula 7 or solving formula 7 and formula 8 may result in that multiple sets of target lighting parameters satisfy formula 7 or satisfy formula 7 and formula 8, and since the power of the lamp is proportional to the gear, in order to minimize the energy consumption of the lighting system, the embodiment of the present disclosure selects a set of lighting parameters with the smallest sum of the lighting parameters of each lighting unit as the target lighting parameters.
In one possible embodiment, as shown in fig. 4, the method may further include:

And under the conditions that the target illumination configuration instruction is not received, the user is in the target area, and the current time is not within a preset time range, configuring the first target illumination and/or the second target illumination according to a fifth preset target illumination and/or a sixth preset target illumination.
The first target illumination and the second target illumination can be configured according to various modes, so that the environmental adaptability and the flexibility of the control of the lighting system are improved.
The configuration of the first target illuminance and/or the second target illuminance at step S10 will be described in an exemplary manner.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating an illuminance control method according to an embodiment of the disclosure.
In one example, as shown in fig. 5, a worker may set a first target illumination and a second target illumination of a first location and/or a second location by using a remote controller, a touch panel, a mobile phone app, and the like, and since the worker may subjectively set the illumination of any workstation at any time, the embodiment of the present disclosure first determines whether a person sets each workstation.
In one example, as shown in fig. 5, for a workstation with a set position (Aj ═ 1), the first target illumination and the second target illumination of the first position and/or the second position may be set by a human, so as to ensure the satisfaction degree of individuals with different illumination preferences. If not, continuing to perform the next judgment.
