[0021] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] To address the limitation in lighting comfort caused by lighting fixtures in related technologies only providing a single light field distribution effect, the first embodiment of this application provides a lighting control method applied to lighting fixtures, such as... Figure 1 The diagram shows a schematic of the lighting assembly of a lighting fixture provided in this embodiment. A first light source 101 is disposed in the central light-emitting area of ​​the lighting fixture, and a second light source 102 is disposed in the light-emitting area outside the first light source 101. The first light source 101 is a colored light source, and the second light source 102 is a white light source. Preferably, in this embodiment, the lighting area corresponding to the first light source 101 is a reading / work area, which can also be called a region of interest (ROI), and the lighting area corresponding to the second light source 102 is the entire work surface area. Preferably, in this embodiment, the illuminance of the first light source is greater than 0 lx, the illuminance of the second light source is greater than 300 lx and less than 2000 lx, and the combined illuminance of the first and second light sources is greater than 500 lx.

[0023] It should be noted that in this embodiment, the first light source may include multiple colored light-emitting units. The first light source can be a multi-color light source, such as an RGB light source or an RGBW light source, or it can be a single-color light source, such as an R light source, a G light source, or a B light source. Preferably, this embodiment uses an RGB light source. Figure 2 The diagram shows the spectrum of an RGB light source provided in this embodiment. A wavelength of 455nm corresponds to the B light source, 525nm to the G light source, and 625nm to the R light source. The second light source may include multiple white light-emitting units. Furthermore, it should be noted that the lighting fixture in this embodiment has multiple sets of second light sources, which are respectively located on different sides of the first light source. Preferably, this embodiment has two sets of second light sources, respectively located on opposite sides of the first light source. The first light source emits an inner light spot, and the second light source emits an outer light spot. The inner light spot is strictly limited to a low-purity color, with a purity ≤0.3, and the inner and outer light spots create a color contrast. Figure 3The diagram shown is a spectral schematic of a dual-color-temperature full-spectrum white light source provided in this embodiment. Furthermore, the two sets of second light sources can be low color-temperature white light sources (e.g., color temperature of 2700K) and high color-temperature white light sources (e.g., color temperature of 6500K) to form a dual-color-temperature optical system, thereby achieving a more flexible color temperature range to meet the light color requirements under various conditions.

[0024] like Figure 4 The diagram shown is a flowchart of the lighting control method provided in this embodiment. The lighting control method includes the following steps:

[0025] Step 401: Obtain the overall lighting parameters corresponding to the target lighting effect according to the lighting control command.

[0026] Specifically, in this embodiment, the lighting control command can be a user-input control command, a control command received from other terminal devices, or a lighting control command triggered by the luminaire itself according to preset conditions. In practical applications, different lighting control commands correspond to different target lighting effects, and each target lighting effect is achieved by combining the overall lighting parameters of the mixed light from the first light source and the second light source. It should be understood that the first light source in this embodiment is an effect light used to adjust the lighting effect of the lighting environment in the reading work area, and the second light source is a base light used to provide basic lighting for the entire work surface area.

[0027] In some embodiments of this example, the step of obtaining the overall lighting parameters corresponding to the target lighting effect according to the lighting control command includes: obtaining the natural colors to be presented according to the lighting control command; and determining the overall lighting parameters accordingly based on the natural colors; wherein the lighting parameters include the spectrum.

[0028] Specifically, the natural colors in this embodiment include the colors of natural light and the colors of actual objects in nature. In practical applications, users can input lighting control commands to select the desired natural light or the colors and spectra of actual objects in nature to be presented by the lighting fixtures. Then, based on the spectral composition of the first and second light sources, spectral similarity algorithms and color difference algorithms are used to determine the overall spectrum of the mixed light from the first and second light sources. Spectral similarity measurements include various methods such as distance measurement, angle measurement, and spectral polygon-based measurement. It should be understood that this embodiment has a pre-built spectral index database, which includes the mapping relationships between different natural colors and spectra.

[0029] In some other embodiments of this example, the step of obtaining the overall lighting parameters corresponding to the target lighting effect according to the lighting control command includes: in response to the lighting control command, obtaining the rhythmic stimulus value and / or equivalent melatonin illuminance value corresponding to the lighting environment at the current moment; and determining the overall lighting parameters accordingly based on the rhythmic stimulus value and / or equivalent melatonin illuminance value; wherein the lighting parameters include light purity and / or hue.

[0030] Specifically, this embodiment has a pre-set CS database and / or EML database. Based on the current lighting environment, the corresponding CS value and / or EML value are determined. Then, based on the CS value and / or EML value, the purity and / or hue of the mixed light emitted by the lighting fixture are further determined to ensure that the lighting effect of the lighting fixture is adapted to the current lighting environment.

[0031] Furthermore, in some embodiments of this example, before the step of determining the overall lighting parameters according to the rhythmic stimulus value and / or equivalent melatonin illuminance value, the method further includes: obtaining the target color contrast index between the first light source and the second light source; correspondingly, the step of determining the overall lighting parameters according to the rhythmic stimulus value and / or equivalent melatonin illuminance value includes: combining the rhythmic stimulus value and / or equivalent melatonin illuminance value with the target color contrast index to determine the overall lighting parameters.

[0032] Specifically, in practical applications, the inner and outer light spots form different spectra. This embodiment optimizes the reading environment by combining the contrast of the inner and outer light spots with the overall rhythm characteristics. It should be understood that the overall rhythm characteristics are the comprehensive rhythm values ​​of the overall light environment received by the human eye.

[0033] Furthermore, in some other embodiments of this example, before the step of determining the target lighting parameters corresponding to the first light source based on the overall lighting parameters and the default lighting parameters corresponding to the second light source, the method further includes: obtaining the material reflection characteristics of the reading area corresponding to the first light source; obtaining the target color contrast index between the first light source and the reading area based on the material reflection characteristics; and determining the corresponding local lighting parameters based on the target color contrast index. Accordingly, the step of determining the target lighting parameters corresponding to the first light source based on the overall lighting parameters and the default lighting parameters corresponding to the second light source includes: combining the overall lighting parameters, the default lighting parameters corresponding to the second light source, and the local lighting parameters to determine the target lighting parameters corresponding to the first light source.

[0034] Specifically, in this embodiment, while considering the color contrast between the inner and outer light spots, the color contrast between the inner light spot and the reading work area it illuminates is also considered. This embodiment determines the corresponding local lighting parameters by the material reflection characteristics of the reading work area, and then combines the lighting parameters determined based on the overall lighting parameters and the default lighting parameters corresponding to the second light source to finally determine the target lighting parameters corresponding to the first light source.

[0035] Furthermore, in some embodiments of this example, the step of obtaining the rhythmic stimulus value and / or equivalent melatonin illuminance value corresponding to the lighting environment at the current moment includes: querying a first database based on the current moment to obtain the corresponding first rhythmic stimulus value and / or first equivalent melatonin illuminance value; wherein, the first database includes the mapping relationship between the rhythmic stimulus value and / or equivalent melatonin illuminance value and the time; querying a second database based on the scene feature information corresponding to the lighting environment to obtain the corresponding second rhythmic stimulus value and / or second equivalent melatonin illuminance value; wherein, the second database includes the mapping relationship between the rhythmic stimulus value and / or equivalent melatonin illuminance value and the scene feature information; and combining the first rhythmic stimulus value and / or first equivalent melatonin illuminance value and the second rhythmic stimulus value and / or second equivalent melatonin illuminance value to determine the rhythmic stimulus value and / or equivalent melatonin illuminance value of the lighting environment at the current moment.

[0036] Specifically, in this embodiment, the corresponding rhythmic stimulation value and / or equivalent melatonin illuminance value are obtained according to the time (i.e., time characteristics) and scene characteristics, respectively. Then, the two characteristic parameters are combined to further determine the characteristic parameters that are finally in line with the lighting environment at the current time. Thus, by comprehensively considering the two factors of time and scene characteristics, the parameters finally determined can meet the light effect adaptability of the lighting environment to the greatest extent.

[0037] In some embodiments of this example, before the step of obtaining the overall lighting parameters corresponding to the target lighting effect according to the lighting control command, the method further includes: obtaining the current lighting parameters of the first light source and the default lighting parameters of the second light source; determining the mixed lighting parameters by combining the current lighting parameters and the default lighting parameters; determining the current light receiving position of the user's retina based on the mixed light chromaticity in the mixed lighting parameters; and triggering the lighting control command if the current light receiving position is determined to meet the preset conditions.

[0038] Specifically, in practical applications, different colored lights are projected onto the user's retina at different locations. The different locations of the retina projected by some colored lights can cause changes in the optical structure of the eye, thereby affecting the normal development of the eye. Therefore, this embodiment determines the location of the light projected onto the user's retina based on the mixed colorimetry of the first and second light sources during the current lighting process. If it is determined that the light irradiation behavior at this retinal location will affect the development of the user's eyes during the application period, a lighting control command is triggered to execute the subsequent lighting control process.

[0039] Furthermore, in some embodiments of this example, the step of triggering a lighting control command when the front light receiving position is determined to meet the preset conditions includes: determining the corresponding light safety tolerance time based on the current light receiving position; and triggering a lighting control command when the continuous lighting duration of the lighting fixture reaches the light safety tolerance time.

[0040] Specifically, the light safety tolerance time in this embodiment is the duration of safe tolerance supported by the continuous reception of light at the retinal position. In this embodiment, considering that different retinal positions have different tolerance capabilities for light reception, the corresponding light safety tolerance time is determined for the current retinal position receiving light. When the duration of continuous illumination of the current colored light exceeds the safe tolerance time of the retinal position receiving the colored light, an illumination control command is triggered to execute subsequent illumination control, change the position of the retina receiving the colored light, and ensure the normal development of the eye structure.

[0041] Furthermore, in some embodiments of this example, the step of obtaining the overall lighting parameters corresponding to the target lighting effect according to the lighting control command includes: determining the target light receiving position of the user's retina according to the lighting control command; and determining the overall lighting parameters accordingly based on the target light receiving position; wherein the lighting parameters include colorimetry.

[0042] Specifically, in this embodiment, after triggering the lighting control command, the light receiving position that the retina needs to change is determined. In practical applications, the target light receiving position can be determined based on the current light receiving position carried by the lighting control command, and then the chromaticity corresponding to the position mapped to that position can be determined based on the determined target light receiving position.

[0043] Step 402: Based on the overall lighting parameters and the default lighting parameters corresponding to the second light source, determine the target lighting parameters corresponding to the first light source.

[0044] Specifically, in this embodiment, the second light source emits light using default lighting parameters, which are the fixed lighting parameters of the second light source. The lighting parameters of the first light source, however, are dynamically configured in relation to the target lighting effect. Since the overall lighting parameters are a mixture of the first and second light sources, this embodiment can determine the target lighting parameters required for the first light source based on the known overall lighting parameters and the default lighting parameters of the second light source. It should be noted that in practical applications, the scenario for configuring the target lighting parameters in this embodiment can be when the lighting fixture triggers a lighting action, or when the lighting fixture is already in a lighting state.

[0045] Step 403: Control the first light source to work according to the target lighting parameters, and control the second light source to work according to the default lighting parameters.

[0046] Specifically, in this embodiment, the second light source can be controlled to operate with default lighting parameters. The operating parameters of the second light source need to be dynamically configured according to the desired lighting effect. In practical applications, this embodiment controls the first light source to operate with target lighting parameters that are adapted to the target lighting effect. As a result, the first light source and the second light source are superimposed in the reading area, and the resulting mixed light is user-friendly.

[0047] Following the aforementioned implementation of lighting control for protecting retinal health, in some embodiments of this embodiment, the step of controlling the operation of the first light source according to the target lighting parameters includes: determining the corresponding multicolor light ratio according to the target lighting parameters; and controlling the operation of multiple different colored light-emitting units of the first light source according to the multicolor light ratio.

[0048] Specifically, in this embodiment, the first light source is a multi-color light source including different colored light-emitting units. In this embodiment, the proportion of different colored lights can be adjusted by adjusting the ratio of the multi-color lights. Taking the first light source including red and blue light-emitting units as an example, adjusting the proportion of the multi-color lights, that is, adjusting the ratio of red light to blue light, can ultimately achieve the desired overall colorimetric value of the first light source.

[0049] In some embodiments of this example, before the step of controlling the first light source to operate according to the target illumination parameters, the method further includes: acquiring scene perception data corresponding to the reading operation area of ​​the first light source in response to an illumination control command; identifying the area boundary range of the reading operation area based on the scene perception data; and determining the corresponding local illumination parameters based on the area boundary range; wherein the local illumination parameters include the beam angle. Accordingly, the step of controlling the first light source to operate according to the target illumination parameters includes: controlling the first light source to operate by combining the local illumination parameters and the target illumination parameters.

[0050] Specifically, in this embodiment, considering that the required reading area varies depending on the user's different reading tasks, and that providing a first light source illumination range that matches the actual reading task area is necessary to ensure good lighting effects, this embodiment collects data on the actual reading task area during the actual lighting process. Preferably, a camera imaging method is used, but other sensors can also be used in other implementations. Then, the boundary range of the reading task area is identified based on the collected data to locate the range of the reading task area. Furthermore, the beam angle of the first light source is determined according to the size of the reading task area so that the illumination range of the first light source matches the actual reading task area during the actual lighting process.

[0051] It should be noted that in practical applications, this embodiment can employ projection technology, such as micro-LED arrays, DMD arrays, liquid crystal arrays, etc., to achieve pixel-level precise control; or, an optical focusing system can be used to control the size of the light source beam angle, controlling the first light source to illuminate the reading work area for imaging; or, a mechanical method can be used to adjust the first light source using multiple sets of different beam angles according to the needs of the reading work area.

[0052] Based on the technical solution of the above embodiments of this application, the overall lighting parameters corresponding to the target lighting effect are obtained according to the lighting control command; based on the overall lighting parameters and the default lighting parameters corresponding to the second light source, the target lighting parameters corresponding to the first light source are determined; the first light source is controlled to work according to the target lighting parameters, and the second light source is controlled to work according to the default lighting parameters; wherein, the first light source is provided in the middle light-emitting area of ​​the lighting fixture, and the second light source is provided in the light-emitting area of ​​the lighting fixture located outside the first light source; the first light source is a colored light source, and the second light source is a white light source. Through the implementation of the solution of this application, the lighting fixture can achieve a full-spectrum, layered light environment, dynamically adjust the inner layer colored light source to improve the overall lighting effect, and effectively improve the comfort and eye protection of the lighting environment.
