The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
Fig. 1 is a schematic diagram of an illumination system 1000 according to an embodiment of the present invention. The lighting system 1000 comprises a lighting device 100, the lighting device 100 comprises a dimming control means 110, a distance sensing means 120 connected to the dimming control means 110, a lighting means 130, a communication means 140 and an indicating means 150. The lighting system 1000 further comprises an external terminal device 200 in communication with the lighting device 100.
The distance sensing device 120 is configured to obtain distance data between the lighting device 100 and the illuminated object, 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, and specifically, the light source 131 is any single or color light source. The communication device 140 is used for communicating with the external terminal device 200 to receive external adjustment data, and the indicating device 150 is used for displaying the distance between the lighting device 100 and the illuminated object.
Wherein the dimming control means 110 comprises 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 a 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, so as to instruct 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 illumination adjustment data and the second illumination adjustment data include at least one of light intensity, beam angle, and 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 light according to the first light adjustment data, so as to instruct the light emitting device 130 to output the light according to the second light adjustment data. The dimming control device 110 further includes an updating module 114, configured to update 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 with reference to fig. 1, a specific flow of the method may be as follows:
step S101, the dimming control means 110 is initialized. In this embodiment, the initializing includes setting preset lighting conditions, which are light intensity, beam angle, and color temperature of the initial operation of the lighting device 100. 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 means 110 comprises setting a preset lighting condition to the previously maintained operating state of the lighting device 100.
In step S102, the dimming control device 110 receives distance data between the lighting apparatus 100 and the illuminated object under the preset lighting condition. Specifically, the dimming control device 110 reads the distance data from the distance sensing device 120 according to a certain frequency. In an embodiment, the distance sensing device 120 is an active infrared sensor, and in other embodiments, the distance sensing device 120 may be another infrared array sensor, which can sense distance information between the lighting device and the illuminated object, and some depth information of the illuminated object to calculate the relative size of the illuminated object.
In step S103, the calculation module 112 of the dimming control device 110 calculates the first illumination adjustment data according to the received distance data and the 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 device 110, where the preset adjustment model includes a plurality of sub-adjustment models, and in the present embodiment, includes at least one of a distance and light intensity adjustment model, a distance and light beam angle adjustment model, and a distance and color temperature adjustment model. When a certain distance data is input, the sub-algorithm model calculates a recommended value (i.e., first illumination adjustment data) of at least one of the corresponding light intensity, beam angle, and color temperature. In other embodiments, the calculating module 112 may also input the received distance data and the 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 device 110 outputs first indication information to the light source 131 to instruct the light source 131 to output illumination according to the first illumination adjustment data. Specifically, the dimming control device 110 outputs a related instruction to adjust the state of the lighting apparatus 100, and after the adjustment, the lighting apparatus 100 maintains the state until the dimming control device 110 receives the instruction to adjust to the next state.
For example, after initializing the dimming control device 110, the user selects a lighting mode, i.e., a preset lighting mode library is stored in a memory (not shown) in the dimming control device 110 for selection by the user, and typical exemplary lighting modes include, but are not limited to, a clothing mode, a fresh mode, an advertisement mode, a portrait mode, and a museum mode as shown in table one below. The illumination pattern has a recommended value range of at least one of light intensity, beam angle, and color temperature corresponding to a specific distance range set by the system. The beam angle is matched by obtaining depth information of the object to be irradiated according to the distance data and further calculating the size of the object to be irradiated.
Schema library name Distance range Color temperature range Light intensity range
Clothing pattern 0.5-3 m 4000-6500K 30-100％
Fresh mode 0.5-2 m 4000-6500K 30-80％
Advertisement mode 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 lighting pattern library
For example, when the lighting apparatus 100 is a spotlight for a clothing store, the user sets the lighting apparatus 100 to a clothing mode, and the dimming control means 110 sets a color temperature recommended value in this mode to 5000K; if the distance between the spotlight and the irradiated clothes is relatively short (for example, less than 2 meters), the light intensity is properly reduced to 60%, so that the visual perception of the irradiated clothes is improved, and stronger glare is not generated; in addition, if the garment to be irradiated is a child garment, since the child garment has a smaller area than an adult garment, it is necessary to appropriately reduce the beam angle, for example, the beam angle of the spotlight from 24 degrees to 12 degrees, in order to exhibit the visual feeling of the object to be irradiated and the overall environmental atmosphere.
In step S105, the receiving module 111 of the dimming control device 110 receives the second illumination adjustment data from the external terminal device 200. In particular, in a specific lighting mode, each time the calculated distance and intensity, distance and beam angle, distance and color temperature data will be stored in the memory. Meanwhile, if the illumination effect adjusted according to the preset adjustment model is not ideal, the user may input the second illumination adjustment data through the external terminal device 200 to adjust again. The second illumination adjustment data is also stored in the memory.
In step S106, after the light source 131 outputs the light according to the first light adjustment data, the output module 113 of the dimming control device 110 outputs second indication information to the light source 131 to instruct the light source 131 to output the light according to the second light adjustment data.
Fig. 3 is a schematic flow chart of updating a preset adjustment model according to an embodiment of the present invention, and with reference to fig. 1, a specific flow of the method may be as follows:
in step S201, the memory of the dimming control device 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, optimizing the saved distance data, the first illumination adjustment data and the second illumination adjustment data by an interpolation method to obtain optimized third illumination adjustment data. In the present embodiment, the interpolation method is a data processing method known to those skilled in the art for acquiring, for example, an intermediate value (for example, an intermediate value of distance data).
Step S203, updating the optimized third illumination adjustment data into a preset adjustment model. By continuously accumulating and iterating, the lighting device 100 will have self-adaptive adjustment capability, i.e. automation capability, so as to adjust the light intensity, the light beam angle and the color temperature to the state calculated by the preset adjustment model in a specific scene at a specific distance, thereby realizing self-learning and iterative upgrading. In this way, the lighting device 100 itself will be provided with intelligent automated adjustment functionality.
