Detailed Description

Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

In order to solve the above problem, the lighting control method for breeding provided by the present disclosure may include:

Between the different periods of breed cycle, when carrying out the illumination condition and switch over, through illumination intensity and the colour gradual change that control illumination lamps and lanterns shone for the animal of breeding can adapt to the change of illumination gradually, can eliminate the irritability problem that the illumination condition sudden change brought, is applied to the in-process of breed, can reduce under the inconvenient condition of breed cycle, dies, improves production efficiency.

The cultivation period may refer to a time required for cultivating a certain organism from putting seedlings to a commodity specification. In a possible implementation mode, the culture cycle can be divided into a plurality of different periods for different organisms, and the feeding amount, the illumination time, the illumination color, the temperature, the humidity and other conditions of the different periods can be controlled, so that the culture efficiency is improved.

The first color may be the color of light having a wavelength in the range 580nm-595nm, for example yellow, and the second color may be the color of light having a wavelength in the range 420nm-450nm, for example blue. The above definition of the first color and the second color is only one example of the present disclosure and does not limit the present disclosure in any way. The first color and the second color may also be other colors for different farming scenes.

The lighting fixture may include a first light source capable of Emitting a first color light and a second light source capable of Emitting a second color light, and may include, for example, a yellow LED (light Emitting diode) and a blue LED. The lighting fixture may also include light sources of other colors, as the present disclosure is not limited in this respect.

In one possible implementation, the second illumination may be less than the first illumination. It should be noted that the present disclosure is not limited thereto, and the magnitude relationship between the first illumination and the second illumination may be determined according to the scene of the specific application, for example, the first illumination may also be smaller than the second illumination.

Taking the breeding of white-feather chickens as an example, the breeding cycle of the white-feather chickens can be 38 days, and the breeding cycle can be divided into two different periods for the illumination condition: 1-19 days and 20-38 days, wherein yellow light is required to be irradiated within 1-19 days and blue light is required to be irradiated within 20-38 days. However, when the yellow light on day 19 is switched to the blue light, stress problems are likely to occur in the chicks, which causes the food intake and water intake of the chicks to be reduced within 1-2 days after the light change, and the production efficiency is affected.

In one possible implementation, the first period may be day 16-24 of the white-feather chicken breeding cycle. Still taking the cultivation cycle as 38 days as an example, that is, the cultivation cycle can be divided into three different periods: 1-15 days, 16-24 days and 25-28 days.

Gradual change may refer to a transition from one state to another gradually, through some intermediate state, rather than abruptly changing between the two states.

In one example, from a start time of the first period to an end time of the first period, the color of the light controlled to be illuminated by the lighting fixture is gradually changed from the first color to the second color, which may be: from the start time of the first period to the end time of the first period, the proportion of the first color of the light irradiated by the lighting fixture is controlled to be uniformly reduced from 1 to 0, and simultaneously the proportion of the second color is controlled to be uniformly increased from 0 to 1, and the sum of the proportion of the first color and the proportion of the second color is 1.

The proportion of the first color may refer to a specific gravity of the first color among all colors, and similarly, the proportion of the second color may refer to a specific gravity of the second color among all colors.

Fig. 1 illustrates a schematic diagram of a process of illuminance and color change of a breeding illumination control method according to an embodiment of the present disclosure, and table 1 illustrates data of illuminance and color change according to an embodiment of the present disclosure.

As shown in fig. 1 and table 1, the ratio of yellow and blue was 1 and 0, respectively, on day 16, 0.875 and 0.125, respectively, on day 17, 0.75 and 0.25 … …, respectively, on day 18, and so on, and 0 and 1, respectively, on day 24.

In one possible implementation, the method is described by taking an example in which the lighting fixture includes a yellow LED and a blue LED. Fig. 3 shows a schematic LED particle connection diagram of a lighting fixture according to an embodiment of the present disclosure.

The lighting fixture shown in fig. 3 includes a blue LED particle module and a yellow LED particle module connected in parallel; the blue LED particle module may include 3 sets of blue LED particle groups connected in parallel, and the yellow LED particle module includes 3 sets of yellow LED particle groups connected in parallel. The blue LED particle module and the yellow LED particle module are connected in parallel, so that the LEDs with two different colors can be independently controlled; the LED particles of each color are grouped and connected in parallel, and the grouped control of the light source with single color can be realized.

When the LED particles with different colors are combined to emit light, the number of the light-emitting particles of the LED particles with different colors can be adjusted through the independent control of the LED particle groups with one or more colors, so that the color of the light irradiated by the lighting lamp can be adjusted.

It should be noted that the connection manner of the LEDs in fig. 3 is only an example of the present disclosure, and does not limit the present disclosure in any way, and each LED may also be connected in an individually controlled manner, so as to achieve finer color adjustment.

In one example, the controlling the illuminance of the lighting fixture to gradually change from the first illuminance to the second illuminance from the start time of the first period to the end time of the first period may be: and controlling the illumination intensity of the lighting lamp to be linearly changed from the first illumination intensity to the second illumination intensity from the starting time of the first period to the ending time of the first period.

As shown in fig. 1, the linear change of the illuminance of the lighting fixture from the first illuminance to the second illuminance may be a continuous linear change of the illuminance, for example, the illuminance is continuously and linearly decreased from 13.2 to 2.4, and the change curve is-1.35 x +34.8, where x represents time and y represents an illuminance value.

As shown in table 1, the linear change of the illuminance of the control lighting fixture from the first illuminance to the second illuminance may be a uniform change of the illuminance which is discrete by day, and as shown in table 1, the illuminance is decreased by 1.35LX every day, and the illuminance is maintained for one day.

					1-15	13.2	10	0	10

24	2.4	0	10	10

It should be noted that, in all embodiments of the present disclosure, the adjustment of the illuminance may be to adjust the illuminance of the light source that is turned on in the lighting fixture, so as to adjust the illuminance of the lighting fixture.

Through the cultivation illumination control method of the embodiment, when illumination conditions are switched, illumination intensity and color irradiated by the illumination lamp are controlled to gradually change, so that cultivated animals can gradually adapt to illumination change, the problem of irritability caused by sudden change of illumination conditions can be solved, and when the cultivation illumination control method is applied to cultivation, death can be reduced and production efficiency can be improved under the condition that a cultivation period is inconvenient.

In one example, controlling the illuminance of the lighting fixture to gradually change from the first illuminance to the second illuminance from a start time of the first period to an end time of the first period may include: and controlling the illumination intensity of the lighting lamp to change from the first illumination intensity to the second illumination intensity in a stepwise manner from the starting time of the first period to the ending time of the first period.

Specifically, controlling the illuminance of the lighting fixture to change stepwise from the first illuminance to the second illuminance may refer to controlling the illuminance of the lighting fixture to transition from the first illuminance to the second illuminance through at least one intermediate illuminance. Wherein the intermediate illuminance may be an illuminance value located within a first illuminance and a second illuminance interval.

In the case where a plurality of intermediate illuminances are included, the illuminance values of the plurality of intermediate illuminances may be different and arranged in order of magnitude, for example, in order of magnitude to magnitude. The difference between the illuminance values of each two adjacent intermediate illuminances may be the same or different, and this disclosure does not limit this.

For example, as shown in table 1, the first period may be divided into a plurality of sub-periods (one sub-period is for each day in table 1), the illuminance corresponding to each sub-period is controlled to change stepwise from large to small, and the difference between the illuminance values of each two adjacent intermediate illuminances in table 1 is the same. In other examples, the difference in luminance values for each adjacent two intermediate illuminances may also be different.

In one possible implementation, controlling the illuminance of the lighting fixture to change stepwise from the first illuminance to the second illuminance from the start time of the first period to the end time of the first period may include:

In one possible implementation, the third illuminance may be an average of the first illuminance and the second illuminance.

The lengths of the first sub-period, the second sub-period and the third sub-period may be the same or different, and may be set according to actual needs, which is not limited in the present disclosure.

Fig. 2 shows a schematic diagram of the illuminance and color change process of the cultivation illumination control method according to an embodiment of the disclosure. As shown in fig. 2, the first sub-period may be day 16, the second sub-period may be days 17-23, and the third sub-period may be day 24. The first luminance value may be 13.2LX and the second luminance value may be 2.4LX, and thus the third luminance value may be 7.8 LX. Within 16 days, the illuminance of the lighting fixture changed linearly from 13.2LX to 7.8 LX; the illumination of the lighting lamp is maintained to be 7.8LX within the days 17 to 23; within day 24, the illuminance of the lighting fixture varied linearly from 7.8LX to 2.4 LX.

It should be noted that the method of fig. 2 above is only one example of the present disclosure, and does not limit the present disclosure in any way. The length of the first sub-period, the second sub-period and the third sub-period, and the illuminance values of the first illuminance, the second illuminance and the third illuminance can be set by those skilled in the art according to actual needs.

In one example, controlling the color of light illuminated by the lighting fixture to gradually change from a first color to a second color from a start time of the first time period to an end time of the first time period comprises:

wherein the transition color may be a color in which a first color and a second color are mixed in a first ratio, and the first ratio may be greater than 0 and less than 1.

In the case where a plurality of transition colors are included, the first ratios among the plurality of transition colors may be different and arranged in order of magnitude, for example, in order of from large to small. The difference of the first ratio between each two adjacent transition colors may be the same or different, and the disclosure does not limit this.

For example, as shown in table 1, the first period may be divided into a plurality of sub-periods (one sub-period is for each day in table 1), the first ratio of the transition color corresponding to each sub-period is controlled to change stepwise from large to small, the difference of the first ratios of each two adjacent transition colors in table 1 is different, and in other examples, the difference of the first ratios of each two adjacent transition colors may be the same.

The first sub-period, the second sub-period, and the third sub-period may refer to the above description, and are not repeated.

In one possible implementation, the first ratio of the first color and the second color in the transition color may be 0.5.
