The intelligent lighting control system aims to provide a system which can realize human-computer interaction and control an external lighting system.
The selection device is used for realizing man-machine interaction, and providing options of expected lighting modes for people to select. The options for selecting the illumination pattern that the device may provide include at least: a first illumination mode, a second illumination mode, a third illumination mode, and a fourth illumination mode.
The first illumination mode is mainly focused on static illumination. The control program corresponding to the first lighting mode is stored by the local device or the cloud device. When the first lighting mode needs to be operated, the control device may call a corresponding control program to implement the first lighting mode. For convenience of description, the control program corresponding to the first illumination mode is referred to as a static light execution program. The static light executive emphasizes that the illuminance value of the light output by the controlled external lighting system is stable and unchanged as a result of the execution. In this embodiment, the running of the static execution program is specifically represented as: the control device acquires a first target illuminance value from the local device or the cloud device, and controls an external lighting system to output the first target illuminance value. The first target illumination value is preset for a user and is stored in the local device or the cloud device.
The second lighting mode is mainly used for emphasizing rhythm lighting, and a control program corresponding to the second lighting mode is stored by the local device or the cloud device. When the second lighting mode needs to be operated, the control device may call a corresponding control program to implement the second lighting mode.

The rhythm light executing program, when executed, emphasizes that the light output by the external lighting system to be controlled is influenced by the time and the ambient illuminance value of the environment in which it is located. In this embodiment, the specific expression of the running rhythm light execution program is as follows: the control device obtains a current time value and an ambient illuminance value of an environment in which the external lighting system is located. And the control equipment accesses the local equipment or the cloud equipment, and inquires the local equipment or the cloud equipment according to the current time value and the environment illumination value to obtain a target color temperature value, a target spectrum value and a second target illumination value. The control device controls an external lighting system to output the target color temperature value, the target spectrum value and the second target illuminance value.
The third illumination mode mainly emphasizes illumination of dynamic light, which means that dynamic light having a training effect on human eyes can be output. And the control program corresponding to the third lighting mode is stored by the local equipment or the cloud equipment. When the third lighting mode needs to be operated, the control device may call the corresponding control program to implement the third lighting mode. For convenience of description, the control program corresponding to the third illumination mode is referred to as a dynamic light execution program. When the dynamic light executing program is executed, the result of the emphasis is that the output light of the controlled external lighting system is dynamic, so as to generate the so-called 'eye vision system three-linkage' in the visual field, thereby achieving the purpose of exercising the eyes of the user. In this embodiment, the operation of the dynamic optical execution program is specifically represented as: the control device controls an external lighting system to output illumination light of at least one light variation process. Wherein, the illumination light of at least one light change process acts on the eyes of the user, and makes the eye structure muscle of the user passively change to adapt to the illumination light.
The fourth illumination mode mainly emphasizes the transition between dynamic light and static light. And the control program corresponding to the fourth lighting mode is stored by the local device or the cloud device. When the fourth lighting mode needs to be operated, the control device may call a corresponding control program to implement the fourth lighting mode. For convenience of description, the control program corresponding to the fourth illumination mode is referred to as a periodic light execution program. The periodic light executive, when executed, emphasizes that the light output by the external lighting system being controlled is periodically switched between dynamic light and static light. In this embodiment, the operation of the periodic optical execution program is specifically represented as: the control device runs a static light executive and a dynamic light executive periodically. In some preferred embodiments, in the periodic light execution program, the execution interval time of the dynamic light execution program is less than or equal to 30 min. That is, the control device will run the dynamic light executive every 30min to control the external lighting system. Preferably, the interval time between the setting of the two dynamic light execution programs is also random, and a predetermined template can be adopted or the user can set the interval time by himself. If the interval time between the two dynamic light execution programs is set to be 15 min-25 min, the random time a can be obtained by performing random operation on the local or cloud end immediately after the fourth lighting mode is executed, the dynamic light execution program is performed immediately after the time a, the random time b is obtained by performing random operation on the local or cloud end immediately after the dynamic light execution program is executed, the dynamic light execution program is performed immediately after the time b, the random time c is obtained by performing random operation on the local or cloud end immediately after the dynamic light execution program is executed, the random time c is obtained (the random time c is 15min < c <25 min), the dynamic light execution program is executed immediately after the time c, and the like.
It should be noted that the control device and the external lighting system may be connected by a necessary driving module to achieve the desired effect.
In order to facilitate human-computer interaction of a user, in some preferred specific embodiments, the selection device is provided with a first human-computer interaction button, a second human-computer interaction button, a third human-computer interaction button and a fourth human-computer interaction button, where the first human-computer interaction button is used to obtain a trigger of the user and consider that the user selects a first lighting mode from the selection device; the second human-computer interaction button is used for acquiring the trigger of the user and considering that the user selects a second lighting mode from the selection equipment; the third human-computer interaction button is used for acquiring the trigger of the user and considering that the user selects a third lighting mode from the selection equipment; the fourth human-computer interaction button is used to retrieve the user's trigger and consider the user to select a fourth lighting mode from the selection device.
The first human-computer interaction button, the second human-computer interaction button, the third human-computer interaction button and the fourth human-computer interaction button are arranged on the selection equipment. The man-machine interaction capability of the selection device is increased through the form of the buttons. It should be noted that the first human-computer interaction button, the second human-computer interaction button, the third human-computer interaction button, and the fourth human-computer interaction button may be physical buttons or virtual buttons executed by a program. Wherein, the first human-computer interaction button is triggered to consider that the user selects the first illumination mode. The second human-machine-interaction button is triggered and the user is considered to have selected the second illumination mode. The third human-machine-interaction button is triggered and the user is considered to have selected the third illumination mode. The fourth human-machine-interaction button is triggered considering that the user has selected the fourth lighting mode.
The selection device is a hardware device constructed by the prior art. In some preferred embodiments, the selection device comprises a cell phone.
The specific method for controlling the device to output dynamic light in the external lighting system comprises the following steps: the control device controls an external lighting system to output the illumination light of at least one light change process; the illumination light of the at least one light variation process acts on the eyes of the user and causes the eye structure muscles of the user to passively vary to accommodate the illumination light.
The illumination light that outputs the at least one light variation process is output by the illumination system. After the illumination system is activated, it can then output illumination light of at least one light profile. Through the change of the illumination light, the eye structure of the user can cause the muscle of the user to move passively due to the change of the input light, and the eye protection training of the user is realized through the passive movement mode.
It is known from some studies that a change in the illumination parameters can have a sufficiently perceptible effect on the visual senses and enable the iris of the user's eye to actively adjust the size of the pupil, and thus the luminous flux entering the eye, without the user conscious. Thus, the iris moves following the change of the illumination light. The movement of the iris can drive the ciliary muscle to move, and the movement of the ciliary muscle can drive the movement of the crystalline lens, so that the so-called eye visual system three-linkage in the field of vision is generated, and the purpose of exercising the eyes of a user is achieved.
The dynamic illumination method for eye protection training outputs illumination light in a light change process through the illumination system, and the illumination light in the light change process acts on the eyes of a user, so that the eye structure muscles of the user are passively changed to adapt to the illumination light. Thereby realizing the purpose of eye protection training for the eyes of the user.
It has particular physical properties for the illumination light of the light variation process. Wherein the range of the vertical illumination intensity of the illumination light acting on the eyes of the user is 50lx-10000 lx;
during each light change: the maximum illumination of the illumination light is more than or equal to 1000lx, and the corresponding point of the illumination light and the color temperature always falls into a comfort area of a Koreux curve; each light variation process is divided into: a plurality of sub-variation processes in which the ratio between the minimum illuminance value and the maximum illuminance value of the illumination light is less than or equal to 0.5; the illumination light continuously changes at a set change rate, and the change range of the illumination light is 1.02R-1.2R or 0.8R-0.98R, wherein R is the initial illumination value of the illumination light in the set unit time; wherein, in the sub-variation process, the ratio of the duration that the illumination value of the illumination light is less than 100lx to the total time of the whole light variation process is more than 0% and less than or equal to 10%; the ratio of the time for which the illumination value of the illumination light is greater than 1000lx to the total time of the entire light variation process is 10% or less. Preferably, the illumination value of the illumination light is greater than 1000lx and less than 2433.6lx, and the ratio of the duration to the total time of the entire light variation process is 10% or less.
In order to better describe the illumination light in the light variation process, the following description is made with specific examples. Table 1 below gives the parameters of the illumination light for a light profile of 10 s.
| Illuminance value | Color temperature | Rate of change of illuminance value (per 0.1s) | Same illumination change rate change time(s) | |
| Second 0 | 50lx | 2500K | 10% | 1 |
| Second 1 | 100lx | 2700K | 8% | 2 |
| Second 3 | 260lx | 3400K | -3% | 2 |
| Second 5 | 104lx | 2700K | 10% | 2 |
| 7 th second | 312lx | 4000K | 8% | 2 |
| 9 th second | 811.2lx | 5000K | 20% | 1 |
| Second 10 | 2433.6lx | 6500K |

The light change process in table 1 is divided into 6 sub-change processes, and the first sub-change process is performed from 0 th second to 1 st second, the second sub-change process is performed from 1 st second to 3 rd second, the third sub-change process is performed from 3 rd second to 5 th second, the fourth sub-change process is performed from 5 th second to 7 th second, the fifth sub-change process is performed from 7 th second to 9 th second, and the sixth sub-change process is performed from 9 th second to 10 th second.
