Example two

Referring to fig. 5, a flowchart of a light control method according to a second embodiment of the present invention is shown, where the light control method includes:

step S100, obtaining the brightness of ambient light around a lamp, and controlling an adaptive power supply of the lamp to be started when the brightness is smaller than a threshold value brightness;

step S300, acquiring the ambient air humidity of the lamp in real time, and generating a dimming program to be executed according to the ambient air humidity of the lamp and the preliminary dimming program of the lamp;

step S500, controlling the adaptive power supply of the lamp to switch to the dimming program to be executed.

Specifically, in step S100, the adaptive power supply of the lamp is controlled to be turned on or off according to the brightness of the ambient light around the lamp. 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.

In step S300, after the adaptive power supply is turned on, the humidity sensor on the 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 the outer side of the lamp and is used to sufficiently 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 brings the obtained ambient air humidity of the lamp into the preliminary dimming program of the lamp to generate a new dimming program, that is, the dimming program to be executed.

In step S500, after obtaining the dimming program to be executed, the adaptive power supply of the lamp is controlled to switch to the dimming program to be executed, specifically, the adaptive power supply is generally controlled by a program, a sensor, or an artificial control, where switching to the dimming program to be executed by the adaptive power supply means that the adaptive power supply is controlled by the dimming program to be executed, so that the adaptive power supply supplies electric energy to the light source assembly of the lamp according to the dimming program to be executed, and here, the light source assembly is controlled to be turned on and off and output power of the circuit switch mainly according to a time stipulated by a program, that is, the light is turned on, turned off and the color temperature is changed according to the time stipulated by the dimming program to be executed, so that the light-on time of the lamp and/or the color temperature of the lamp is not constant, these all match with the surrounding environment, generate the dimming procedure of waiting to carry out according to ambient air humidity and preliminary dimming procedure, control the self-adaptation power execution dimming procedure of waiting to carry out carries out multi-mode lighting control to lamps and lanterns, promote lamps and lanterns lighting control's variety, and better adaptation ambient environment promotes the lighting efficiency of lamps and lanterns, can reduce the maintenance cost to lamps and lanterns lighting control simultaneously.

Referring to fig. 6, a flowchart of another method of a light control method according to a second embodiment of the present invention is shown, where in this embodiment, step S300 generates a to-be-executed dimming program according to the ambient air humidity of the lamp and the preliminary dimming program of the lamp, and specifically includes:

step S310, when the humidity of the air around the lamp is smaller than a preset humidity, setting the preliminary dimming program as the dimming program to be executed; alternatively, the first and second electrodes may be,

and S320, when the ambient air humidity of the lamp is greater than the preset humidity, adjusting the preliminary dimming program according to the corresponding relation between the preset air humidity value and the color temperature to generate the dimming program to be executed.

Specifically, in step S310, when the humidity of the air around the lamp obtained by the humidity sensor on the lamp is less than the preset humidity, it indicates that the humidity of the air around the lamp is small, that is, it can be determined that there is no rain or fog in the environment around the lamp, and it is not necessary to consider the influence of the color temperature of the LED light source on the lighting effect, and at this time, the preliminary dimming program may be set as the dimming program to be executed.

Specifically, in step S320, when the humidity of the ambient air of the lamp obtained by the humidity sensor on the lamp is greater than the preset humidity, it is indicated that the humidity of the ambient air of the lamp is relatively high, that is, it can be determined that the ambient environment of the lamp is raining or fog exists, at this time, the influence of the color temperature of the LED light source on the lighting effect needs to be considered, the processor adjusts the preliminary dimming program according to the corresponding relationship between the preset air humidity value and the color temperature to generate the dimming program to be executed, that is, the dimming program to be executed at this time takes into account the environmental humidity factor, so that the color temperature of the LED light source under the control of the dimming program to be executed can be well matched with the ambient environment, and the dimming program has a relatively good lighting effect, specifically, such that the street lamp still has a relatively good lighting degree in the rainy or fog environment.

Further, referring to fig. 7, in step S320, the adjusting the preliminary dimming program according to the preset corresponding relationship between the air humidity value and the color temperature to generate the dimming program to be executed includes:

step S321, determining a color temperature corresponding to the ambient air humidity of the lamp according to a preset corresponding relation between the air humidity value and the color temperature;

step S322, substituting the color temperature corresponding to the ambient air humidity of the lamp into the preliminary dimming program to generate the dimming program to be executed.

Specifically, a corresponding relation table of an air humidity value and a color temperature is stored in the lamp in advance, and the color temperature corresponding to the brightest LED light source in the humidity environment can be obtained from the air humidity value through the relation table. Fig. 8a and fig. 8b are graphs showing the relationship between the air humidity and the lamp brightness under two different color temperatures, respectively. As shown in the figure, when the humidity of the air increases, the color temperature of the lamp light needs to be reduced if a better light brightness is to be obtained. And after the color temperature corresponding to the ambient humidity is obtained, the color temperature is substituted into the preliminary dimming program to generate a dimming program matched with the environment at the moment, namely the dimming program to be executed. In the dimming program to be executed, the output power of the lamp can be adjusted to obtain the color temperature suitable for the surrounding environment, so that the lamp has a good lighting effect, and particularly, the street lamp still has good lighting intensity in a rainy or foggy environment.

Further, referring to fig. 9, in another preferred embodiment of the present invention, on the basis of the above embodiment, after the step S100 controls the adaptive power supply of the lamp to be turned on, the light control method further includes:

step S210, counting the lighting time of N days before the day of lamp counting, wherein N is an integer greater than 1 and less than 11;

step S220, matching an initial dimming program from a plurality of preset dimming programs of the lamp according to a statistical result;

specifically, in step S210, counting the lighting time duration N days before the day, where the lighting time duration refers to the time duration between the lighting time of the evening and the lighting time of the next morning, where N is an integer greater than 1 and less than 11, that is, N is any one of 2, 3, and 4 … 10, and may be specifically selected according to the actual requirement, and the reason why N is any one of 2, 3, and 4 … 10 is selected is that if N selects 1, the randomness is too strong and is not accurate enough; if N is selected to be other number greater than 10, the selected historical data is too long and has no reference meaning, and it is known that the natural illumination time length of a region changes uniformly and slightly in a period (generally, one week), that is, it is more accurate to determine the next lighting time length by the lighting time length of the previous week, and the data which is too far has no meaning or even has a large deviation value of the result, so that the accuracy of the data can be ensured in the preferred embodiment that N is generally an integer greater than 1 and less than 6; as used herein, taking 15 days as a statistical day and N as 3 as an example, the statistical lighting duration of N days before the statistical day of the lighting fixture means: the lighting time periods of 12 days, 13 days and 14 days are counted respectively, for example, the counted results are 9h, 9.1h and 9.2h respectively.

In step S220, a plurality of dimming programs, such as a winter dimming program, a summer dimming program, a spring and autumn dimming program, are stored in the memory of the lamp, and of course, the above dimming programs are only examples, and in practical applications, other various dimming programs may also be stored in the memory of the lamp, and these dimming programs are used to control the lighting duration of the lamp, but not limited to the lighting duration of the lamp, for example, the winter dimming program used in winter may control the lamp to have a longer lighting duration, and the summer dimming program used in summer may control the lamp to have a shorter lighting duration, so that the lighting duration of the lamp matches with the natural lighting duration, thereby achieving the effect of saving power resources; and selecting a dimming program matched with the statistical structure from the plurality of preset dimming programs as a corresponding initial dimming program according to the statistical result of the lighting time of N days before the statistical day, wherein if the statistical result is that the lighting time of three days before the statistical day is respectively 9h, 9.1h and 9.2h, the dimming program matched with the statistical result may be the spring and summer dimming program, and the spring and summer dimming program is selected as the initial dimming program.

Further, please refer to fig. 10 as a flowchart of another method of the lighting control method according to the second embodiment of the present invention, wherein the step S210 of counting the lighting duration of N days before the day includes:

step S211, recording the opening time and the closing time of the self-adaptive power supply of the lamp;

step S212, calculating the lighting time length according to the opening time and the closing time;

step S213, counting the lighting time of N days before the day.

Specifically, in step S211, a timer is provided in the lamp, and the timer is used for recording the on-time and the off-time of the lamp adaptive power supply, where the table 1 below shows the on-time and the off-time of the lamp adaptive power supply recorded by the timer:

TABLE 1

In step S212, the lamp calculates a difference between two adjacent on-times and off-times according to the on-time and off-time of the lamp adaptive power source recorded by the timer to obtain the lighting time, where the difference is calculated by calculating a difference between the on-time and the off-time of two adjacent days, instead of the difference between the on-time and the off-time of the same day, because the lamp is generally turned off in the morning from the evening of the previous day.

In step S213, after obtaining a plurality of lighting time durations through the difference calculation, the different lighting time durations are counted, specifically, the lighting time durations N days before the counted day are counted, where N is an integer greater than 1 and less than 11, and for the specific value of N, reference may be made to the description of the above embodiment, which is not described herein again. In addition, data obviously deviating from the normal brightness duration is excluded during statistics, as shown in table 1, the lighting duration of the lamp in 11 days is 11 hours and 30 minutes, and the lighting durations before and after the day are between 9 hours and 30 minutes and 10 hours, so that the lighting duration of the lamp in 11 days is obviously beyond the normal lighting duration, the exclusion processing should be given during statistics, and the lighting duration of the data after the exclusion processing, which does not meet the requirement of N days, is generally selected to be filled.

In addition, referring to fig. 11, a flowchart of a method for controlling light according to a second embodiment of the present invention is shown, where step S220 matches an initial dimming program from preset dimming programs of the lamp according to a statistical result, and specifically includes:

step S221, carrying out weighted average on the lighting time lengths of N days before the statistical day to obtain the average lighting time length;

step S222, the plurality of dimming programs respectively correspond to standard lighting time intervals, and the initial dimming program is matched according to the standard lighting time interval in which the average lighting time is located.
