The method for adjusting the brightness of the lighting device in the embodiment of the present application is described below with reference to the accompanying drawings.
As shown in fig. 3, a method 300 for adjusting the brightness of a lighting device according to an embodiment of the present application is shown. The method 300 includes:
s310, the first lighting device receives the first indication information from the first terminal device. The first indication information is used for indicating a deviation between a first illumination intensity required by a user of the first terminal equipment and a second illumination intensity currently perceived by the first terminal equipment.
In some embodiments, the first illumination intensity demanded by the user of the first terminal device is greater than the second illumination intensity currently perceived by the first terminal device, i.e. the deviation indicated by the first indication information is a positive value. Illustratively, the first terminal device is the terminal device 200, and the first illumination intensity input by the user input module 203 is greater than the second illumination intensity currently perceived by the illumination perception module 202. For example, the first illumination intensity input by the user input module 203 is 200 lux, the second illumination intensity of the current environment perceived by the illumination perception module 202 is 100 lux, and the first indication information is used to indicate 100 lux.
In some embodiments, the first illumination intensity demanded by the user of the first terminal device is smaller than the second illumination intensity currently perceived by the first terminal device, i.e. the deviation indicated by the first indication information is a negative value. Illustratively, the first illumination intensity input by the user input module 203 is greater than the second illumination intensity currently perceived by the illumination perception module 202. For example, the first illumination intensity input by the user input module 203 is 100 lux, the second illumination intensity of the current environment perceived by the illumination perception module 202 is 200 lux, and the first indication information is used to indicate-100 lux.
And S320, the first lighting device adjusts the brightness of the first lighting device according to the first indication information and the first illuminance deviation proportion information.
In some embodiments, the first lighting device receives third indication information from the second terminal device, the first lighting device determines a third brightness variation amount that the first lighting device needs to adjust according to a deviation between the first illumination intensity and the second illumination intensity indicated by the first indication information and the first illumination deviation proportion information, the first lighting device determines a fourth brightness variation amount that the first lighting device needs to adjust according to a deviation between a fourth illumination intensity and the fifth illumination intensity indicated by the third indication information and the third illumination deviation proportion information, and the first lighting device compares the magnitudes of the third brightness variation amount and the fourth brightness variation amount; if the third brightness variation is larger than the fourth brightness variation, the first lighting equipment adjusts the brightness of the first lighting equipment according to the first indication information and the first illumination deviation proportion information to meet the requirement of the first terminal equipment user; if the third brightness variation is smaller than the fourth brightness variation, the first lighting device adjusts the brightness of the first lighting device according to the third indication information and the third illumination deviation proportion information to meet the requirement of the second terminal device user; and if the third brightness variation is equal to the fourth brightness variation, the first lighting device meets the requirements of the first terminal device user and the requirements of the second terminal device user according to the adjustment of the brightness of the first lighting device.
In some embodiments, the first illuminance deviation ratio information is used to indicate a deviation ratio of a first luminance change amount of the first lighting device and a first illumination intensity change amount perceived by the first terminal device, where the first illumination intensity change amount is an illumination intensity change amount perceived by the first terminal device in a case where the luminance of the first lighting device changes, i.e., the first luminance change amount.
In some embodiments, the first illumination device outputs different brightness at different time instants, that is, the first illumination device outputs a first brightness and a second brightness at different time instants, and a difference between the first brightness and the second brightness is a first brightness variation. In addition, the distance between the first terminal device and the first lighting device is such that the first lighting device can perceive it when changing the output brightness of the first lighting device. The first terminal device senses the first illumination intensity variation when the first illumination device outputs the first brightness variation, the first terminal device sends the sensed first illumination intensity variation to the first illumination device, and the first illumination device obtains first illumination deviation proportion information according to the first brightness variation and the first illumination intensity variation.
Illustratively, the first lighting device is the structure shown by the lighting device 100, and the first terminal device is the structure shown by the terminal device 200. The first brightness variation amount of the first lighting device is determined by the input power of the lighting module 102 of the first lighting device controlled by the control module 101 of the first lighting device, and the input power of the lighting module 102 is determined by the voltage pulse width controlled by the control module 101 of the first lighting device through the PWM technique. Formulating a relationship between the first illumination intensity variation amount and the first luminance variation amount as:
ΔLux＝γ*ΔP (1)
where Δ Lux represents a first illumination intensity variation perceived by the illumination perception module 202 of the first terminal device, Δ P represents a first luminance variation of the illumination module 102 of the first illumination device, that is, an input power variation of the illumination module 102, and γ represents first illumination deviation ratio information. As can be seen from equation (1), the first illuminance deviation proportion information is a positive value. In the process of determining the first illuminance deviation proportion information, the first lighting device changes the brightness of the first lighting device so that the first terminal device can sense the change of the illumination intensity, the brightness of other lighting devices except the first lighting device is unchanged, the time for obtaining the first illuminance deviation proportion information is short, the external natural environment cannot cause serious influence, and the accuracy of the obtained first illuminance deviation proportion information is high.
In some embodiments, after the first lighting apparatus obtains the first illuminance deviation ratio information according to the first luminance variation and the first illumination intensity variation, the first lighting apparatus stores the first illuminance deviation ratio information, and the first lighting apparatus adjusts the luminance of the first lighting apparatus according to the first indication information and the first illuminance deviation ratio information stored in the first lighting apparatus with reference to formula (1). For example, the first indication information is 100 lux, the first illuminance deviation ratio information is 2, and the control module 101 of the first lighting apparatus 100 controls the input power of the lighting module 102 to be increased by 50 watts using the PWM technique.

For example, the first indication information is 100 lux, the first illuminance deviation ratio information is 2, the control module 101 of the first lighting apparatus 100 controls the input power variation speed of the lighting module 102 to be 25 watts per second by using the PWM technique, and the input power variation of the lighting module 102 is adjusted to be 50 watts within 2 seconds.
