Please refer to FIG. 1 to FIG. 6 , the first embodiment of the present invention is:

A LED lighting control method for human-induced lighting, as shown in Figure 1, includes the following steps:

S1. Obtain and confirm the target lamp selected by the user;

In this embodiment, as shown in FIG. 2 and FIG. 6 , a visual operation interface is formed through a mobile phone application, a computer or a web page. When selecting a target luminaire, the user can also enter the scene mode on the operation interface of the system, select a scene according to the actual use requirements or create a scene by himself, including the scene display icon, the associated target luminaire and whether the scene is hidden, etc., and then continue to complete. The selection of step S2 and step S3 finally obtains a lighting scene customized for oneself.

S2. Provide a circadian rhythm table that contains the mapping relationship between all-day time nodes and the color temperature value of the lamp and is used to adjust the color temperature value of the target lamp, as the first control point for the user to select;

In this embodiment, the circadian rhythm table is provided with a plurality of time nodes according to the time distribution of the whole day. Each time node corresponds to a luminaire color temperature value, so as to realize the adaptive regulation of the luminaire color temperature from morning to night. In addition, the user can implement operations such as creating and merging nodes by long-pressing, dragging, and other operations on the operation interface. Not only that, the selection of the color temperature value of the lamps is also related to the weather forecast data of the time node, and the color temperature value can be adjusted according to the predicted weather of the time node. For example, when it is known that the weather at a certain time point in the day is cloudy, the color temperature value of the lamp at that time point is correspondingly increased, so that the optical fiber of the target lamp is closer to natural light, avoiding light pollution, and improving the user experience.

S3. Set a variety of lighting control modes based on the real-time data of the sensor and serve as the second control point for the user to choose;

In this embodiment, as shown in FIG. 6 , the lighting control mode belongs to the sunlight sensing mode for the user to choose, and the following four control modes are set in total:

S31, setting the basic control mode through the detection data of the illuminance sensor and the human body movement sensor;

As shown in Figure 2, the basic type is as follows:

Obtain the light-on threshold or light-off threshold set by the user and compare it with the ambient brightness value collected by the illuminance sensor in real time to determine whether to turn on or off the target lamp;

The human motion sensor detects whether there is a person in the irradiation area of the target lamp. If there is and the target lamp is on, the target lamp is kept on, otherwise the target lamp is turned off.

S32. Mainly set a control type control method through the detection data of the illuminance sensor;

As shown in Figure 3, the control type is specifically:

A first linear relationship between the dim level set by the user and the lux level is obtained, and the brightness of the target lamp is adjusted according to the first linear relationship and the lux data collected by the sensor.

In this embodiment, the drawing is only one of multiple first linear relationships between the dim level and the lux level, and the actual linear relationship can be adjusted by the user by adjusting one of the dim level and the lux level to correspond to the other at the maximum value. Change the value of one side.

S33. Mainly set a constant illumination type control mode through the detection data of the illuminance sensor;

As shown in Figure 4, the constant illumination type is specifically:

Obtain the preset illuminance and tolerance value set by the user, and determine whether the difference between the preset illuminance and the real-time illuminance collected by the sensor is less than the tolerance value.

In this embodiment, in addition to the illuminance value preset by the user, the allowable deviation from the expected illumination is adjusted in combination with the installation environment, outdoor light, indoor illumination area and its usage habits, that is, the required adjustment of the brightness of the lamp is changed. sensitivity. For example, for a target luminaire close to a window, when there are clouds or other objects passing outside the window, the brightness of the light around the target luminaire changes briefly, and the illuminance of the target luminaire will not be automatically adjusted under the effect of the allowable deviation from the expected illumination. , so you only need to wait for the ambient brightness to recover, reducing unnecessary brightness adjustment and saving power. Moreover, the constant illuminance control mode enables the target lamp to maintain a relatively constant illuminance, which can relieve the user's visual fatigue and protect the eyesight.

S34. Mainly set the external control mode through the sensor;

As shown in Figure 5, the external type specifically includes:

A second linear relationship between the dimming signal of different percentages set by the user and the dim level is obtained, and the dimming signal is sent according to the second linear relationship to adjust the brightness of the target lamp.

In this embodiment, the dimming signal is a control signal including [0%, 100%]. For illumination regulation from an external device, the dimming signal can be converted through a sensor, and then the regulation target signal is output.

Not only that, in the above-mentioned control method, the light collection of the sensor may be affected by the light of other nearby lamps, so you can calibrate the illuminance value, adjust the detection sensitivity, set the response time of the illuminance value change, and adjust the tolerance to set how much light is needed. Illumination changes will be counteracted in response to other methods to achieve system response accuracy.

S4. Control the target light fixture according to the user's selection and the preset priority relationship between the first control point and the second control point.

In this embodiment, the user can choose not to add the circadian rhythm table or the lamp control method for regulation when formulating the scene, and set the first control point when both the first control point and the second control point are used. The point has priority over the second control point. Moreover, the priority of the manual control mode is higher than that of the first control point and the second control point at the same time.

In addition, in this embodiment, after completing the above selection, the user can also perform scene simulation, that is, simulate the control mode selected by himself in the virtual scene of the operation interface, and the sampling value of the illuminance sensor is also simulated by data. to enable users to preview the final effect of their settings to determine whether they meet their needs.
