Example two
Referring to fig. 5, a flowchart of a lighting control method according to a second embodiment of the present invention is shown, where the lighting control method includes:
step S100, acquiring the ambient air humidity of the lamp in real time, and determining the light-emitting angle and the color temperature of the lamp corresponding to the air humidity value according to the ambient air humidity of the lamp;

and step S300, controlling the self-adaptive power supply of the lamp to be switched to the dimming program to be executed.
Specifically, in other preferred embodiments of the present invention, before step S100, the light fixture may further control the adaptive power supply of the light fixture to be turned on or off according to the brightness of the ambient light around the light fixture. Here, the light-sensitive sensor is arranged on the lamp, which is generally arranged at the top end of the outer part of the lamp, is used for sufficiently sensing the external environment light so as to obtain the brightness of the environment light around the lamp, the lamp can also realize the control of turning on and off the lamp according to the brightness of the ambient light around the lamp, namely, the adaptive power supply of the lamp is controlled to be switched on or switched off according to the change situation of the brightness of the ambient light around the lamp, if the brightness of the ambient light around the lamp becomes larger than a certain value, the adaptive power supply of the lamp is controlled to switch off the power supply circuit, otherwise, if the brightness of the ambient light around the lamp becomes smaller than a threshold brightness, the adaptive power supply of the lamp is controlled to switch on the power supply circuit, and the self-adaptive power supply of the lamp is started, namely, the photosensitive control of the switch of the lamp is realized.
Further, after the adaptive power supply is turned on, the controller of the lamp controls the adaptive power supply to execute an initial dimming program of the lamp for illumination. Here, the initial dimming program is stored in a storage module of a processor of the luminaire when the luminaire leaves a factory, and after the adaptive power supply is turned on, the controller of the luminaire controls the luminaire to execute the initial dimming program of the luminaire for lighting.
In step S100, while the lamp performs the initial dimming procedure to perform illumination, a humidity sensor on a lamp body of the lamp obtains the humidity of the air around the lamp in real time, where the humidity sensor is generally disposed on a side surface outside the lamp and is configured to be in sufficient contact with the external environment to sense and obtain the humidity of the external environment. After the ambient air humidity of the lamp is obtained, the processor of the lamp can determine the light-emitting angle and the color temperature of the lamp corresponding to the obtained air humidity value according to the corresponding relation between the preset air humidity value and the light-emitting angle and the color temperature of the lamp.
In step S200, the processor adjusts an initial dimming program of the lamp according to the lighting angle and/or the color temperature of the lamp to generate a dimming program to be executed, that is, the value of the lighting angle and/or the color temperature is brought into the initial dimming program to replace the original data, so as to generate the dimming program to be executed.
In step S300, after obtaining the dimming procedure to be executed, the adaptive power supply that controls the lamp to switch to the dimming procedure to be executed, specifically, the adaptive power supply generally receives program control, sensor control, or artificial control, where switching the adaptive power supply to the dimming procedure to be executed means that the adaptive power supply receives the dimming procedure to be executed, so that the adaptive power supply supplies power to the light source assembly of the lamp according to the dimming procedure to be executed, and here, the turning on, turning off, brightness, and color temperature of the circuit switch of the light source assembly are mainly controlled according to the time appointed by the dimming procedure, so that the light on time, the light off time, the brightness, and the color temperature of the lamp are changed according to the time appointed by the dimming procedure to be executed, The lighting angle of the lamp and the color temperature of the lamp are not constant, the lighting angle of the lamp and the color temperature of the lamp are matched with the ambient environment, a dimming program to be executed is generated according to the ambient air humidity and the initial dimming program, the adaptive power supply is controlled to execute the dimming program to be executed, multi-mode lighting control is conducted on the lamp, the diversity of lighting control of the lamp is improved, the lamp is better adaptive to the ambient environment, the lighting efficiency of the lamp is improved, and meanwhile the maintenance cost of the lighting control of the lamp can be reduced.
Referring to fig. 6, a flowchart of another method of an illumination control method according to a second embodiment of the present invention is shown, where in this embodiment, on the basis of the foregoing embodiment, in step S200, an initial dimming procedure of the lamp is adjusted according to the light-emitting angle and the color temperature of the lamp to generate a to-be-executed dimming procedure, which specifically includes:
step S210, adjusting the initial dimming program of the lamp for the first time according to the light-emitting angle of the lamp;
step S220, the initial dimming program after the first adjustment is adjusted for the second time according to the color temperature of the lamp to generate the dimming program to be executed.
Specifically, the adjusting process from the initial dimming procedure to the to-be-executed dimming procedure is as follows: firstly, adjusting the initial dimming program of the lamp for the first time according to the light-emitting angle of the lamp; and then, carrying out second adjustment on the basis of the first adjustment according to the color temperature of the lamp so as to obtain the dimming program to be executed. It should be noted here that the order of the above two adjustments may be interchanged, that is, the color temperature may be adjusted first and then the light emitting angle may be adjusted.
Of course, in other preferred embodiments of the present invention, the initial dimming procedure to the to-be-executed dimming procedure may be obtained after one adjustment, for example, the to-be-executed dimming procedure may be obtained after one adjustment of the light emitting angle, or the to-be-executed dimming procedure may be obtained after one adjustment of the color temperature.
