The lighting system 1000 includes a lighting apparatus 100, and the lighting apparatus 100 includes a dimming control device 110, a distance sensing device 120 connected to the dimming control device 110, a light emitting device 130, a communication device 140, and an indication device 150. The lighting system 1000 further comprises an external terminal device 200 communicating with the lighting device 100.
The distance sensing device 120 is used for acquiring distance data between the lighting apparatus 100 and an object to be illuminated, and the light emitting device 130, for example, the light source board 1 (as shown in fig. 5) includes a light source 131 for outputting illumination conditions, specifically, the light source 131 is any single or color light source. The communication device 140 is used for communicating with an external terminal device 200 to receive external adjustment data, and the indication device 150 is used for displaying the distance between the illumination device 100 and the illuminated object.
The dimming control apparatus 110 includes a receiving module 111, a calculating module 112, and an output module 113. The receiving module 111 is configured to receive distance data between the lighting device 100 and the object under the preset lighting condition according to a preset frequency. The calculating module 112 is configured to calculate first illumination adjustment data according to the received distance data and a preset adjustment model, and the output module 113 is configured to output first indication information to the light emitting device 130 to indicate the external light emitting device 130 to output illumination according to the first illumination adjustment data.
Wherein the receiving module 111 further comprises receiving second illumination adjustment data from the external terminal device 200. The first and second lighting adjustment data include at least one of a light intensity, a beam angle, and a color temperature. The output module 113 further outputs second indication information to the light emitting device 130 after the light emitting device 130 outputs the illumination according to the first illumination adjustment data, so as to instruct the light emitting device 130 to output the illumination according to the second illumination adjustment data. The dimming control apparatus 110 further comprises an updating module 114 for updating the preset adjustment model according to the distance data, the first illumination adjustment data, and the second illumination adjustment data.
Fig. 2 is a schematic flow chart of a dimming control method according to an embodiment of the present invention, and as shown in fig. 1, a specific flow of the method may be as follows:
in step S101, the dimming control device 110 is initialized. In the present embodiment, the initialization includes setting preset lighting conditions, which are a light intensity, a beam angle, and a color temperature at which the lighting apparatus 100 initially operates. In one embodiment, the initial light intensity is 100%, the beam angle is 30 degrees, and the color temperature is 5000K. In another embodiment, initializing the dimming control 110 comprises setting a preset lighting condition to an operating state that the lighting fixture 100 previously maintained.
In step S102, the dimming control apparatus 110 receives distance data between the lighting device 100 and the illuminated object under the preset illumination condition. Specifically, the dimming control device 110 reads the distance data from the distance sensing device 120 at a certain frequency. In one embodiment, the distance sensing device 120 is an active infrared sensor, and in other embodiments, the distance sensing device 120 may also be another infrared area array sensor, which is capable of sensing distance information between the lighting apparatus and the object to be illuminated, and some depth information of the object to be illuminated to calculate the relative size of the object to be illuminated.
In step S103, the calculating module 112 of the dimming control apparatus 110 calculates first illumination adjustment data according to the received distance data and a preset adjustment model. Specifically, in the present embodiment, the calculation module 112 inputs the received distance data into a preset adjustment model (i.e., a preset lighting pattern library) stored in the dimming control apparatus 110, where the preset adjustment model includes a plurality of sub-adjustment models, and in the present embodiment, includes at least one of an adjustment model of distance and light intensity, an adjustment model of distance and beam angle, and an adjustment model of distance and color temperature. When a certain distance data is input, the sub-algorithm model calculates a recommended value of at least one of the corresponding light intensity, beam angle, and color temperature (i.e., first illumination adjustment data). In some other embodiments, the calculating module 112 may also input the received distance data and depth information data into a preset adjustment model stored in the dimming control device 110 to calculate the first illumination adjustment data.
In step S104, the output module 113 of the dimming control apparatus 110 outputs first indication information to the light source 131 to indicate the light source 131 to output illumination according to the first illumination adjustment data. Specifically, the dimming control device 110 outputs a relevant instruction to adjust the state of the lighting apparatus 100, and after the adjustment is completed, the lighting apparatus 100 maintains the state until the instruction of the dimming control device 110 is received to adjust to the next state.
For example, after initializing the dimming control apparatus 110, the user selects the lighting mode, that is, a preset lighting mode library is stored in a memory (not shown) in the dimming control apparatus 110 for the user to select, and a common exemplary lighting mode is shown in the following table a, which includes, but is not limited to, a clothing mode, a fresh mode, an advertisement mode, a portrait mode, and a museum mode. The lighting pattern has a recommended value range of at least one of light intensity, beam angle, and color temperature set by the system corresponding to a specific distance range. The beam angle is matched by obtaining the depth information of the object according to the distance data and further calculating the size of the object.
| Schema library names | Range of distances | Range of color temperatures | Light intensity range |
| Clothing model | 0.5-3 m | 4000-6500K | 30-100％ |
| Fresh food mode | 0.5-2 m | 4000-6500K | 30-80％ |
| Advertising model | 0.5-5 m | 5000-6500K | 60-100％ |
| Portrait mode | 0.3-3 m | 2700-6500K | 20-100％ |
| Museum mode | 0.3-3 m | 2700-3000K | 0-60％ |
Table one: preset library of lighting patterns
For example, when the lighting apparatus 100 is a spot lamp for a clothing shop, the user sets the lighting apparatus 100 to a clothing mode, and the dimming control device 110 sets the recommended color temperature value in this mode to 5000K; if the distance between the lamp and the irradiated clothes is short (for example, less than 2 meters), the light intensity is properly reduced to 60 percent, which is beneficial to improving the visual perception of the irradiated clothes without generating strong glare; in addition, if the clothes to be irradiated is children clothes, because the children clothes have a smaller area than the clothes of adults, in order to embody the effect, the beam angle of the spotlight needs to be properly reduced, for example, the beam angle of the spotlight is reduced from 24 degrees to 12 degrees, so that the visual perception and the overall environmental atmosphere of the irradiated objects can be better embodied.
In step S105, the receiving module 111 of the dimming control apparatus 110 receives the second illumination adjustment data from the external terminal device 200. Specifically, in a particular lighting pattern, each time the calculated distance and light intensity, distance and beam angle, distance and color temperature data are stored in the memory. Meanwhile, if the illumination effect adjusted according to the preset adjustment model is not ideal, the user may input second illumination adjustment data through the external terminal device 200 to perform adjustment again. The second lighting adjustment data is also stored in the memory.
In step S106, after the light source 131 outputs the illumination according to the first illumination adjustment data, the output module 113 of the dimming control apparatus 110 outputs second indication information to the light source 131 to indicate the light source 131 to output the illumination according to the second illumination adjustment data.
Fig. 3 is a schematic flow chart of updating a preset adjustment model according to an embodiment of the present invention, and as shown in fig. 1, a specific flow of the method may be as follows:
in step S201, the memory of the dimming control apparatus 110 stores the received distance data, the first illumination adjustment data calculated according to the preset adjustment model, and the second illumination adjustment data input from the external terminal device 200. These adjustment data are correlated with the distance data read by the distance sensing device 120 to form a big data model.
Step S202, the stored distance data, the first illumination adjustment data and the second illumination adjustment data are optimized through an interpolation method, and optimized third illumination adjustment data are obtained. In the present embodiment, the interpolation method is a data processing method for obtaining, for example, an intermediate value (for example, an intermediate value of distance data) well known to those skilled in the art.
Step S203, updating the optimized third illumination adjustment data to a preset adjustment model. Through continuous accumulation and iteration, the lighting device 100 has self-adaptive adjustment capability, that is, has automation capability, so that the light intensity, the beam angle and the color temperature are adjusted to the state calculated by a preset adjustment model at a specific distance in a specific scene, and self-learning and iterative upgrade are realized. In this way, the lighting device 100 itself will have intelligent automatic adjustment functionality.
