Description

Two-stage polychromatic illumination spectrum for optimizing young bird production
Technical Field
The present invention relates to a light generating system. The invention also relates to an animal farm system comprising such a light generating system. The invention also relates to a method of providing system light for a home. Still further, the invention relates to a specific light generating device.
Background
The use of light in animal breeding or rearing is known in the art. For example, US2017/0000163 describes a method of increasing feed consumption of an avian comprising: providing a poultry house system located within the enclosure, wherein the poultry house system comprises an interior volume for containing birds; the feed of the bird is irradiated with light from an artificial light source having a spectrum of less than 400 nanometers (nm) to consume the feed by the bird. The spectrum is between 380nm and 400 nm. The artificial light source has a plurality of light emitting diodes providing the spectrum.
WO2020/043649A discloses a light generating device comprising a first light source of a first light and a second light source of a second light, wherein the second light comprises cyan-like light having a wavelength selected from the range 470-520nm, and wherein the first light is white light, and the device outputs white light enriched in the cyan-like light.
US2012/002408A discloses a lighting fixture for a poultry house comprising an elongated body and a transparent cover coupled to the body and configured to create an interior space with the body. The first LED is disposed in the inner space and emits light having a first color. The second LED is disposed in the interior space and emits light having a second color different from the first color. The controller independently controls the output of the first LED and the second LED.

The lighting state of the lighting device is automatically controlled by the control module.
Disclosure of Invention
Feeding poultry for commercial production requires strict control of environmental factors including temperature, humidity, ventilation, feed and water, and light. Modern broilers grow from 40 g of newly hatched chickens to as much as 5 kg in 8 weeks of growth time. In view of this tremendous shift, environmental management requirements vary significantly over the lifetime of chickens. During the first 7-10 days of life (known as "brooding"), chickens need special care to ensure that their body temperature remains high enough, and they learn to look for food and water. In the later stages of their life (20 days harvesting or through sexual maturation, called "growth"), chickens need an environment supporting a large consumption of feed and water and a non-aggressive space to rest. It appears that light of different wavelengths has different biological effects on poultry. Furthermore, it appears that during the feeding period, different types of light may be desired.
It is therefore an aspect of the present invention to provide an alternative light generating system, which preferably further at least partly obviates one or more of the above-mentioned drawbacks. It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
For example, it appears that red light promotes activities such as eating and drinking, and also aggressiveness. Thus, red light may be advantageous during brooding, but may be less desirable during growth. Blue and green light appear to promote muscle growth and weight gain. Blue light tends to relax the birds and reduce motion.
If the known lighting system is applied in a poultry house, a "cool" white LED employing a blue LED with red + green phosphor may provide the light. Such an illumination system may have a spectrum of fixed wavelengths that does not change during the feeding process.
Surprisingly, it appears that the relative intensity can be advantageously controlled for optimal feeding. Surprisingly, it was observed that the green spectrum has a biological effect between blue and red light. In particular, it was found that excessive green light may have a similar effect as red light during growth, and birds may exhibit relatively excessive motion and/or fight, resulting in poor feed conversion and poor growth rates. The present invention proposes to use independent control of blue, green and red. Furthermore, it appears that amber light may be applied in addition to or instead of red. Thus, the term "amber-red" herein may refer herein to a wavelength range of 580-750 nm. When light has an intensity (or spectral power) in the amber-red wavelength range, such light (more particularly its spectral power distribution) may have one or more wavelengths (intensities) in the range 580-750 nm.
Thus, in a first aspect, the invention provides a light generating system (especially in embodiments for illumination in poultry houses). In particular, the light generation system may be configured to generate system light having a controllable spectral power distribution and intensity. In an embodiment, in the operation mode, the light generating system may be configured to, in a first period of time P 1 During which a first spectral power distribution E is generated 1 And in particular later in time than the first period P 1 Is a second period P of time 2 During which a second spectral power distribution E is generated 2 .

Furthermore, in an embodiment, the controllable spectral power distribution comprises (b) a second spectral range Λ having one or more green wavelengths 2 . In particular, the second spectral range Λ 2 In a first period of time P 1 With primary second spectral power SP (P) 1 ，Λ 2 ) And at the secondTime period P 2 With a secondary second spectral power SP (P) 2 ，Λ 2 ). Still further, in an embodiment, the controllable spectral power distribution comprises (c) an amber-red spectral range Λ 34 Having one or more amber-red wavelengths.

In particular, in an embodiment, the first period of time P 1 May be selected from at least a portion of a day; second period of time P 2 Selected from a range of at least a portion of a day. Further, in a specific embodiment, SP (P 1 ，Λ 1 ) > 0 Watts, SP (P 1 ，Λ 2 ) > 0 watts, and SP (P 1 ，Λ 34 ) > 0 watts. Still further, in a particular embodiment, the SP (P 2 ，Λ 1 ) > 0 watts, and SP (P 2 ，Λ 2 ) > 0 watts. Still further, in an embodiment, SP (P 2 ，Λ 2 )/SP(P 2 ，Λ 1 )＜SP(P 1 ，Λ 2 )/SP(P 1 ，Λ 1 ). In an embodiment, SP (P 2 ，Λ 34 )/SP(P 2 ，Λ 1 )＜SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 1 ) May also be applicable. However, in the embodiment, SP (P 2 ，Λ 34 )/SP(P 2 ，Λ 2 )＜SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 2 ). Thus, in a specific embodiment, the present invention provides a light generating system (for illumination in a poultry house), wherein the light generating system is configured to generate system light having a controllable spectral power distribution and intensity, wherein in an operational mode the light generating system is configured to, during a first period of time P 1 During which a first spectral power distribution E is generated 1 And later in time than the first period P 1 Is a second period P of time 2 During which a second spectral power distribution E is generated 2 Wherein: (A) The controllable spectral power distribution comprises (a) a first spectral range Λ 1 Having one or more blue wavelengths and during a first period of time P 1 With primary first spectral power SP (P) 1 ，Λ 1 ) During a second period of time P 2 With a secondary first spectral power SP (P) 2 ，Λ 1 ) (b) a second spectral range Λ 2 Having one or more green wavelengths and during a first period of time P 1 With primary second spectral power SP (P) 1 ，Λ 2 ) During a second period of time P 2 With a secondary second spectral power SP (P) 2 ，Λ 2 ) And (c) an amber-red spectral range Λ 34 Having one or more amber-red wavelengths, and during a first period of time P 1 With primary amber-red spectral power SP (P) 1 ，Λ 34 ) And during a second period of time P 2 With a secondary amber-red spectral power SP (P) 2 ，Λ 34 ) The method comprises the steps of carrying out a first treatment on the surface of the (B) First spectral power distribution E 1 Comprising a primary first spectral power SP (P 1 ，Λ 1 ) Primary second spectral power SP (P 1 ，Λ 2 ) And a primary amber-red spectral power SP (P 1 ，Λ 34 ) The method comprises the steps of carrying out a first treatment on the surface of the Second spectral power distribution E 2 Comprising a secondary first spectral power SP (P 2 ，Λ 1 ) Secondary second spectral power SP (P 2 ，Λ 2 ) And a secondary amber-red spectral power SP (P 2 ，Λ 34 ) The method comprises the steps of carrying out a first treatment on the surface of the (C) First time period P 1 At least a portion selected from the group consisting of a day; second period of time P 2 Selected from one dayAt least a portion of the range; (D) SP (P) 1 ，Λ 1 ) > 0 Watts, SP (P 1 ，Λ 2 ) > 0 watts, and SP (P 1 ，Λ 34 ) > 0 watts; SP (P) 2 ，Λ 1 ) > 0 watts, and SP (P 2 ，Λ 2 ) > 0 watts; SP (P) 2 ，Λ 2 )/SP(P 2 ，Λ 1 )＜SP(P 1 ，Λ 2 )/SP(P 1 ，Λ 1 )；SP(P 2 ，Λ 34 )/SP(P 2 ，Λ 1 )＜SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 1 ) The method comprises the steps of carrying out a first treatment on the surface of the And SP (P) 2 ，Λ 34 )/SP(P 2 ，Λ 2 )＜SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 2 )。
The present system can provide (among other things) an optimal ratio between these wavelengths to achieve a desired biological response throughout the production cycle. The invention can increase average chicken weight and reduce feed conversion rate. The invention may also better allow controlling the light according to the type of poultry and/or the feeding objective and/or timing. Furthermore, it appears that with the present system (and method) poultry (such as chickens) may have less stress and/or fear. Preliminary results also appear to indicate that it is even possible to have a positive impact on the immune function of the poultry, as lower stress may be beneficial to the immune system.
The light generating system may be configured to provide system light to the animal home. Animal houses, particularly poultry houses, may house poultry (see also below).
As indicated above, the present invention provides a light generating system, in particular for the illumination of poultry houses. However, other applications are not excluded.
The light generation system may be configured to generate system light having a controllable spectral power distribution and intensity. To this end, the light generating system may comprise a plurality of light sources, such as solid state light sources (see also further below).
The light generating system may be especially capable of providing different types of light. Basically, the light generating system may be especially capable of providing: a first light including one or more of blue, green, and amber and red; and a second light, wherein one or more of the green and amber and red components are reduced relative to the blue component when compared to the relative intensity of the first light. In particular, one or more of the amber and red components may be even further reduced than the green component. In particular, the first light may be provided during a portion of at least several days during an early part of the feeding period and the second light may be provided during a portion of at least several days during a later part of the feeding period. Furthermore, in particular, the light generating system may be capable of gradually changing from light of the first type to light of the second type.
Thus, in an embodiment, in an operational mode, the light generating system may be configured to, in a first period of time P 1 During which a first spectral power distribution E is generated 1 And later in time than the first period P 1 Is a second period P of time 2 During which a second spectral power distribution E is generated 2 。
First time period P 1 May be selected from at least a portion of a day. For example, the first period of time may be at least 8 hours, such as at least 10 hours, such as at least 12 hours, such as at least 14 hours. However, the first period of time may also be longer, such as at least about 16 hours, such as at least about 18 hours, or even longer, such as at least about 20 hours, such as even up to 24 hours. Thus, in a particular embodiment, the first period of time P 1 Can be selected from the range of 8-24 hours. The first period of time may be performed during a plurality of days, such as up to about 10 days, during the first portion of the feeding period (see also below). Second period of time P 2 May (also) be selected from a range of at least a part of a day. For example, the second period of time may be at least 8 hours, such as at least 10 hours, such as at least 12 hours, such as at least 14 hours. However, the second period of time may also be longer, such as at least about 16 hours, such as at least about 18 hours, or even longer, such as at least about 20 hours, such as even up to 24 hours. In particular embodiments, the second period of time may be up to about 22 hours. Thus, in a specific embodiment, the second period of time P 2 Can be in the range of 8-22 hoursAnd (5) selecting. The second period of time may be performed during a plurality of days during the second portion of the feeding period, such as after about 10 days (see also below). The term "one day" refers to a 24 hour period.
Thus, in a particular embodiment, the first period of time P 1 May be selected from the range of 8-24 hours, and the second period of time P 2 May be selected from the range of 8-22 hours.
As can be derived from the above, the controllable spectral power distribution comprises (a) a first spectral range Λ 1 Having one or more blue wavelengths and during a first period of time P 1 With primary first spectral power SP (P) 1 ，Λ 1 ) During a second period of time P 2 With a secondary first spectral power SP (P) 2 ，Λ 1 ) (b) a second spectral range Λ 2 Having one or more green wavelengths and during a first period of time P 1 With primary second spectral power SP (P) 1 ，Λ 2 ) During a second period of time P 2 With a secondary second spectral power SP (P) 2 ，Λ 2 ) And (c) an amber-red spectral range Λ 34 Having one or more amber-red wavelengths, and during a first period of time P 1 With primary amber-red spectral power SP (P) 1 ，Λ 34 ) During a second period of time P 2 With a secondary amber-red spectral power SP (P) 2 ，Λ 34 )。
In particular, in an embodiment, the first spectral range Λ 1 Second spectral range lambda 2 And an amber-red spectral range Λ 34 May be substantially non-overlapping.
In this context, substantially non-overlapping may be, for example, that 5% of the wavelength range that is equal to or less than the smaller wavelength range (in nanometers) overlaps with the larger wavelength range (in nanometers). For example, in the case of wavelength ranges of 580-620nm and 620-750nm, the former wavelength range defines a range of 40nm, and the latter wavelength range defines a range of 130 nm. The overlap may be 1nm (as they may be considered to share a value of 620 nm), which is 2.5% of the 40nm wavelength range. For example, in the case of wavelength ranges of 510-580nm and 580-620nm, the former wavelength range defines a range of 70nm, and the latter wavelength range defines a range of 40 nm. The overlap may be 1nm (as they may be considered to share a value of 580 nm), which is 2.5% of the 40nm wavelength range.
As indicated above and further set forth below, the phrase "amber-red spectral range Λ 34 Having one or more amber-red wavelengths "and similar phrases may refer to embodiments in which an amber light source (one or more wavelengths in the 580-620nm wavelength range) and/or a red light source (one or more wavelengths in the 620-750nm wavelength range) may be applied. In a specific embodiment, at least a red light source is applied. In other embodiments, only amber light sources are applied. In other embodiments, a red light source is applied, and optionally an amber light source is applied.
In an embodiment, a first spectral power distribution E, which may be provided during a first period of time 1 May include a primary first spectral power SP (P 1 ，Λ 1 ) Primary second spectral power SP (P 1 ，Λ 2 ) Primary amber-red spectral power SP (P 1 ，Λ 34 ). A second spectral power distribution E that may be provided during a second period of time 2 Comprising a secondary first spectral power SP (P 2 ，Λ 1 ) Secondary second spectral power SP (P 2 ，Λ 2 ) And a secondary amber-red spectral power SP (P 2 ，Λ 34 )。
In particular, in an embodiment, in the first spectral power distribution, in the first spectral range Λ 1 Second spectral range lambda 2 And an amber-red spectral range Λ 34 There may be a (substantial) intensity. Thus, in an embodiment, SP (P 1 ，Λ 1 ) > 0 Watts, SP (P 1 ，Λ 2 ) > 0 watts, and SP (P 1 ，Λ 34 ) > 0 watts.
In particular, in an embodiment, in the second spectral power distribution (during the second period of time), the spectral power distribution is within the first spectral range Λ 1 May have (substantial) strengthThe method comprises the steps of carrying out a first treatment on the surface of the However, the second spectral range Λ 2 And an amber-red spectral range Λ 34 May decrease in strength, whereby the latter may decrease even more than the former. Thus, in an embodiment, SP (P 2 ，Λ 1 ) > 0 watts, and SP (P 2 ，Λ 2 ) > 0 watts. In particular, the following may apply: SP (P) 2 ，Λ 2 )/SP(P 2 ，Λ 1 )＜SP(P 1 ，Λ 2 )/SP(P 1 ，Λ 1 ) The method comprises the steps of carrying out a first treatment on the surface of the Thus, in the second spectral power distribution, green may be reduced relative to blue. Furthermore, the following may also apply in particular: SP (P) 2 ，Λ 34 )/SP(P 2 ，Λ 1 )＜SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 1 ). Thus, in the second spectral power distribution, one or more of amber and red may be reduced relative to blue. In addition, the following may also apply in particular: SP (P) 2 ，Λ 34 )/SP(P 2 ，Λ 2 )＜SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 2 ). Thus, in the second spectral power distribution, one or more of amber and red may also be reduced relative to green.
In an embodiment, the first spectral range Λ 1 May have one or more wavelengths selected from the wavelength range of 400-470 nm. For example, in an embodiment, the first light source may have a peak wavelength within the wavelength range. In other embodiments, the first light source may have a centroid wavelength within the wavelength range.
The term "centroid wavelength" (also indicated as λc) is known in the art and refers to a wavelength value where half of the light energy is at a shorter wavelength and half of the energy is at a longer wavelength; this value is in nanometers (nm). It is the wavelength that divides the integral of the spectral power distribution into two equal parts, as represented by the formula lambda c Expressed as = Σλx I (λ)/(Σi (λ)), where the sum is over the wavelength range of interest and I (λ) is the spectral energy density (i.e., the integral of the product of wavelength and intensity over the emission band normalized to the integral intensity).
Further, in an embodiment, the second spectral range Λ 2 May have one or more wavelengths selected from the wavelength range of 510-580 nm. For example, in an embodiment, the second light source may have a peak wavelength within the wavelength range. In other embodiments, the second light source may have a centroid wavelength within the wavelength range.
Still further, in an embodiment, the amber-red spectral range Λ 34 May have one or more wavelengths selected from the wavelength range of 580-750 nm. For example, in an embodiment, the amber-red light source may have a peak wavelength within this wavelength range. In other embodiments, the amber-red light source may have a centroid wavelength within that wavelength range. In yet a further embodiment, two amber-red light sources may be applied, one having a peak wavelength in the amber wavelength range and one having a peak wavelength in the red wavelength range. In other embodiments, two amber-red light sources may be applied, one having a centroid wavelength in the amber wavelength range and one having a centroid wavelength in the red wavelength range. Note that the term "light source" may also refer to a plurality of light sources.
Thus, in an embodiment, the first spectral range Λ 1 May have one or more wavelengths selected from the wavelength range 400-470nm, the second spectral range Λ 2 May have one or more wavelengths selected from the wavelength range of 510-580nm, an amber-red spectral range Λ 34 May have one or more wavelengths selected from the range of 580-750nm wavelengths.
In particular, in an embodiment, it may be found that the first spectral range Λ 1 At least 90% of the spectral power of (a) is between 410-470nm, such as between about 420-470 nm. In particular, in an embodiment, the second spectral range Λ may be found 2 At least 90% of the spectral power of (a) is between about 510-575 nm. In particular, in an embodiment, an amber-red spectral range Λ may be found 34 At least 90% of the spectral power of (a) is between about 580-720nm, such as between about 585-720 nm. Thus, in an embodiment, a first spectral range may be foundSurrounding lambda 1 At least 90% of the spectral power of (a) is between about 420-470nm, a second spectral range Λ can be found 2 At least 90% of the spectral power of (a) is between about 510-575nm, and an amber-red spectral range Λ may be found 34 At least 90% of the spectral power of (a) is between about 585-720 nm. In other embodiments, an amber-red spectral range Λ may be found 34 At least 90% of the spectral power of (i) in the range of 580-615nm and (ii) in the range of 620-720 nm.
In an embodiment, the first spectral power distribution may comprise three or four emission bands in the spectral range of 400-750nm, each emission band having a peak maximum, wherein the peak maxima differ from each other by at least 15nm, such as at least 20nm. However, in particular embodiments, the first spectral power distribution may be defined by three or four emission bands, each emission band having a centroid wavelength, wherein the centroid wavelengths differ by at least 15nm, such as at least 20nm, in the spectral range of 400-750 nm.
As indicated above, in an embodiment, in the second spectral power distribution (during the second period of time), the spectral power distribution is within the first spectral range Λ 1 May have (considerable) strength; however, the second spectral range Λ 2 And an amber-red spectral range Λ 34 May decrease in strength, whereby the latter may decrease even more than the former.
In particular, in the embodiment, SP (P 2 ，Λ 2 )/SP(P 2 ，Λ 1 )≤0.9*SP(P 1 ，Λ 2 )/SP(P 1 ，Λ 1 ) Such as SP (P) 2 ，Λ 2 )/SP(P 2 ，Λ 1 )≤0.75*SP(P 1 ，Λ 2 )/SP(P 1 ，Λ 1 ) May be applicable. However, in the embodiment, SP (P 2 ，Λ 2 )/SP(P 2 ，Λ 1 )≤0.6*SP(P 1 ，Λ 2 )/SP(P 1 ，Λ 1 ) May be applicable. Thus, in the second spectral power distribution, green may be reduced relative to blue. In yet a further embodiment, the SP (P 2 ，Λ 2 )/SP(P 2 ，Λ 1 )≥0.1*SP(P 1 ，Λ 2 )/SP(P 1 ，Λ 1 ) Such as SP (P) 2 ，Λ 2 )/SP(P 2 ，Λ 1 )≥0.15*SP(P 1 ，Λ 2 )/SP(P 1 ，Λ 1 ) May be applicable.
Furthermore, in particular in the examples, SP (P 2 ，Λ 34 )/SP(P 2 ，Λ 1 )≤0.5*SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 1 ) Such as SP (P) 2 ，Λ 34 )/SP(P 2 ，Λ 1 )≤0.25*SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 1 ) May be applicable. However, in the embodiment, SP (P 2 ，Λ 34 )/SP(P 2 ，Λ 1 )≤0.15*SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 1 ) May be applicable. Thus, in the second spectral power distribution, one or more of amber and red may be reduced relative to blue.
Furthermore, in particular in the examples, SP (P 2 ，Λ 34 )/SP(P 2 ，Λ 2 )≤0.65*SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 2 ) Such as SP (P) 2 ，Λ 34 )/SP(P 2 ，Λ 2 )≤0.5*SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 2 ) May be applicable. However, in the embodiment, SP (P 2 ，Λ 34 )/SP(P 2 ，Λ 2 )≤0.4*SP(P 1 ，Λ 34 )/SP(P 1 ，Λ 2 ) May be applicable. Thus, in the second spectral power distribution, one or more of amber and red may also be reduced relative to green.
As indicated above, for the amber-red wavelength range, one or more of the red and amber light sources may be applied. It appears that by adding amber to the spectral power distribution (which includes red), the vision of the birds can be improved.

As indicated above, the first spectral power distribution may be especially during a first part of the feeding period ("first feeding period RP") 1 ") and the second spectral power distribution may in particular be provided during a second part of the feeding period (" second feeding period RP ") 2 ") is provided during the period. The first spectral power distribution may be particularly useful in the initial days of the chicks, and the second spectral power distribution may be particularly useful for a period of time after these initial days.
These initial days may be in particular about the first 5-20 days (from the start of hatching), such as about the first 10 days. In particular, the (artificial) light provided to the poultry during the first part of the feeding period may consist essentially of the first spectral power distribution. Thus, in an embodiment, during the second feeding period RP 2 During this time, the (artificial) light provided to the poultry substantially only during the first part of the feeding period may substantially consist of the first spectral power distribution.
During the period following these initial days (i.e. the first feeding period RP 1 Later time period), the (artificial) light provided to the poultry during the first part of the feeding period may generally consist essentially of the first spectral power distribution most of the time. In particular, this period of time may last for at least 10 days.
In an embodiment, the first feeding period RP 1 The first spectral power distribution during the period can be gradually changed to the second feeding period RP 2 A second spectral power distribution of the period. Such changes may be performed in less than one day to several days. Thus, in an embodiment, there may be about 1-5 days, especially 1-3 days, wherein the spectral power distribution may comprise a first spectral power distribution and a second spectral power distribution having a relative contribution that varies over time. In general, a minimum of a first period of time having a first spectral power distribution is provided during a first feeding periodThe number of days may be at least 5 days. Thus, for example, a first feeding period may comprise 5 days, wherein a first period of time has a first spectral power distribution, followed by a second feeding period that begins first with a gradual change in the first spectral power distribution to the second spectral power distribution. During the second feeding period, the number of days for which at least a second photoperiod having a second spectral power distribution is provided may be at least 5 days, even more particularly at least 10 days.
Thus, in an embodiment, in the operating mode, the first feeding period RP is selected from the range of 5-20 days 1 During a first period of time P 1 Each day during which a first spectral power distribution E is provided 1 And then at a second feeding period RP selected from a range of at least 10 days 2 During a second period of time P 2 Each day during which a second spectral power distribution E is provided 2 Is a system light of (a).
For broilers, the second feeding period may be shorter than for example young sires or layers. Thus, in embodiments, particularly for broilers, the first feeding period RP 1 Can be selected from the range of 5-14 days, and the second feeding period RP 2 May be selected from the range of at least 40-60 days. In other embodiments, particularly for young sires or laying hens, the first feeding period RP 1 Can be selected from the range of 5-14 days, and the second feeding period RP 2 May be selected from the range of at least 70-140 days.
The date the chicks hatched and/or removed from the incubator is indicated as day 0.
In embodiments, it may be desirable to control not only the spectral power distribution, but also the intensity of the light. In an embodiment, it appears useful to have a lower light intensity during the second feeding period relative to the first feeding period. Thus, in an embodiment, in an operational mode, the lighting system may be configured to (i) in the first feeding period RP 1 During (in the first period P 1 System light of each day during) at a first luminous flux lm 1 Providing a first spectral power distribution E 1 And (ii) during the second feeding period RP 2 During (in the second period P 2 System light of each day during) at a second luminous flux lm 2 Providing a second spectral power distribution E 2 Wherein lm, on average over the corresponding feeding period 2 ＜lm 1 . For example, in an embodiment, 0.02.ltoreq.lm, on average, over the corresponding feeding period 2 /lm 1 Less than or equal to 0.5. However, in other embodiments, the luminous flux may remain substantially constant throughout the feeding period.
The light generating system may further comprise a control system or may be functionally coupled to the control system. Thus, in an embodiment, the light generating system may further comprise a control system configured to control the controllable spectral power distribution and intensity of the system light. Furthermore, the light generating system may comprise a sensor, which may be functionally coupled to the control system. In particular, in an embodiment, the light generating system may further comprise (i) a control system configured to control the controllable spectral power distribution and intensity of the system light, and (ii) a sensor, wherein the control system is configured to control the controllable spectral power distribution and intensity in dependence of a sensor signal of the sensor.
The term "control" and similar terms especially refer at least to determining the behavior of an element or supervising the operation of an element.

Thus, the term "control" and similar terms may include applying a behavior to an element, as well as applying a behavior to an element and monitoring the element. Control of the element may be accomplished with a control system, which may also be indicated as "controller". Thus, the control system and elements may be functionally coupled, at least temporarily or permanently. The element may comprise a control system. In embodiments, the control system and elements may not be physically coupled. Control may be accomplished via wired and/or wireless control. The term "control system" may also refer to a plurality of different control systems, which are in particular functionally coupled, and of which, for example, one control system may be a master control system and one or more other control systems may be slave control systems. The control system may include or may be functionally coupled to a user interface.
The control system may also be configured to receive and execute instructions from the remote control. In an embodiment, the control system may be controlled via an App on a device such as a portable device (e.g., a smart phone or I-phone, tablet, etc.). Thus, the device is not necessarily coupled to the lighting system, but may be (temporarily) functionally coupled to the lighting system.
Thus, in an embodiment, the control system may be (also) configured to be controlled by an App on the remote device. In such embodiments, the control system of the lighting system may be a slave control system or control in a slave mode. For example, the lighting systems may be identified by codes, in particular unique codes for the respective lighting systems. The control system of the lighting system may be configured to be controlled by an external control system accessing the lighting system based on knowledge of the (unique) code (user interface input through an optical sensor, e.g. a QR code reader). The lighting system may also include means for communicating with other systems or devices, such as bluetooth, WIFI, liFi, zigBee, BLE, or WiMAX based, or other wireless technology.
The system or apparatus or device may perform actions in "mode" or "mode of operation" or "operational mode". Also, in a method, an action or stage or step may be performed in "mode" or "mode of operation" or "operational mode". This does not exclude that the system, or the apparatus, or the device may also be adapted to provide another control mode, or a plurality of other control modes. Again, this does not exclude that one or more other modes may be performed before and/or after the mode is performed.
However, in an embodiment, a control system may be available, which is adapted to provide at least a control mode. The selection of such a mode may in particular be performed via the user interface if other modes are available, although other options (e.g. executing the mode according to a sensor signal or a (time) scheme) may also be possible. In an embodiment, an operational mode may also refer to a system, or apparatus, or device that can only operate in a single operational mode (i.e., "on" with no further tunability).
Thus, in an embodiment, the control system may control based on one or more of the input signal of the user interface, the sensor signal (of the sensor), and the timer. The term "timer" may refer to a clock and/or a predetermined time scheme.
In embodiments, the sensor may include one or more of an optical sensor, a thermal sensor, a sound sensor, and the like. In an embodiment, the sensor may comprise a (digital) camera.

In particular embodiments, the plurality of cameras may be configured to sense animal accommodation. In yet further embodiments, the plurality of cameras may be configured in an animal home, such as in a stable or stable.

In particular embodiments, the sensor may be used to monitor animal behavior. Alternatively or additionally, sensors may be used to monitor the feeding process. In an embodiment, the control system may control one or more of the spectral power distribution and intensity in accordance with the sensor signal of the sensor. Alternatively or additionally, the control system may control one or more of the spectral power distribution and intensity of the local in the animal home based on the sensor signal of the sensor. Thus, also during the first feeding period and/or during the second feeding period, the spectral power distribution may vary, in particular within the respective ranges indicated herein, e.g. as a function of animal behaviour. Alternatively or additionally, in an embodiment, during the second feeding period, it may be desirable to activate the poultry. Thus, in particular embodiments, the sensors and control system may be configured to monitor poultry behavior (and/or feedingProgress), and the control system may be configured to, during a second feeding period RP 2 During (see also above) providing a first spectral power distribution E 1 One or more pulses of system light having a first pulse duration P 3 In which the pulse duration P 3 Selected from a range of up to 4 hours. For example, the pulse duration may be selected from the range of 5 seconds to 4 hours, such as at least 10 seconds. In embodiments, the pulse interval may be selected from 5 seconds to 10 hours or even longer. Thus, in an embodiment, a single pulse may be provided during the entire second feeding period. In other embodiments, multiple pulses may be provided during the same day and/or distributed over multiple days.

In the latter embodiment, the system light may be provided, for example, during at least part of the dark period (night).
The animal farm system may comprise a control system (see also above). In such embodiments, the control system may also control one or more other aspects, such as one or more of temperature in the residence, air composition in the residence, humidity in the residence, food supply to the animal, water supply to the animal, sound supply to the animal, provision of a concentration (enclosure) source or device, provision of a medication, disposal or conditioning of waste, or disposal of waste, among others.

Referring to fig. 2e (and also to fig. 1 a-1 b), the sensor 310 and the control system 300 may be specifically configured to monitor poultry behavior. In an embodiment, the control system 300 may be configured to, during the second feeding period RP 2 During which a first spectral power distribution E is provided 1 One or more pulses of the system light 1001, the one or more pulses of the system light 1001 having a first pulse duration P 3 . In a particular embodiment, the pulse duration P 3 May be selected from a range of up to 4 hours.
In an embodiment, blue, green and red spectra of approximately equal (+/-20%) intensity may be provided during the brooding phase of poultry feeding, and approximately twice (+/-20%) as much blue as green may be provided during the growing phase, and substantially no red, see also fig. 2 a-2 e.
In embodiments, a fourth spectral component (amber) may or may not be included during the brooding stage, which in particular embodiments may be a phosphor-based light source that peaks between green and red. If an amber spectrum is included, the relative intensity of this peak may also be approximately equal to the other peaks during the "brood" phase (+/-20%). In particular embodiments, similar to the red channel, the amber light source light may be substantially completely removed during the growth phase.
In a specific embodiment, the blue spectrum may be defined as a light source having a spectral density output function that results in a maximum peak between 400nm and 470 nm. In a specific embodiment, the green spectrum may be defined as a light source having a spectral density output function that results in a maximum peak between 510nm and 580 nm. In a specific embodiment, the red spectrum may be defined as a light source having a spectral density output function that results in a maximum peak between 580nm and 750 nm. An amber spectrum is defined herein as a light source having a spectral density output function that results in a maximum peak between 580nm and 620 nm.
Based on a number of measurements, in which the effect of the spectral power distribution on poultry, in particular chickens, is tested, the desired spectral power distribution is defined (see above, and see e.g. fig. 2 a).
The optimized illumination spectral ratio may be independent of the light source. It may be achieved by mixing a plurality of light sources or by screening of multispectral light sources. The relative peak intensities may be measured in terms of peak heights or integrated areas under peaks, especially based on the latter (using an energy-based y-scale).
In an embodiment, a specific solution to build the present invention would be to design a circuit with three different LED channels. Channel 1 may contain only blue LEDs (e.g., 450nm peak wavelength). Channel 2 may contain only green LEDs (e.g., 530nm peak wavelength). Channel 3 may contain only red LEDs (e.g., 660nm peak wavelength). The light output from each channel may be controlled individually via a dimming mechanism such as pulse width modulation, current limiting, or phase cutting. In an embodiment, during the brooding phase, all three channels would be driven equally to allow for equal light emission from all channels. During growth, channel 3 may be closed in embodiments, and channel 2 may be dimmed to half the intensity of channel 1 in embodiments; see also fig. 2b.
In an embodiment, the system may also be designed with as few as two channels (see also fig. 2 b). In an embodiment, channel 1 may contain blue LEDs (450 nm peak wavelength) and green LEDs (530 nm), and channel 2 may contain green LEDs (530 nm peak wavelength) and red LEDs (660 nm peak wavelength). The light output from each channel may be controlled individually via a dimming mechanism such as pulse width modulation, current limiting, or phase cutting. During the brooding stage, in an embodiment, two channels may be driven substantially equally to allow for equal light emission from both channels. In an embodiment, during growth, channel 2 may be substantially closed, leaving substantially channel 1 emitting blue and half green intensity spectra.
In an embodiment, the scheduler may be used to define the output of each channel according to the time of day and according to the date of production. The control system may use a scheduler to control the system light.
The system and/or method may be used, among other things, to raise broiler chickens. For example, in embodiments of the invention, the system may be used to raise broiler chickens (broiler chickens). Commercial breeds of broilers may remain as pre-breeding young for a life cycle of less than about 8 weeks. The above described schedule of brooding and growing may only be applicable to commercial varieties of broilers. Other varieties and species may have other defined schedules.
Alternatively or additionally, the system and/or method may be used to feed young sires and laying hens. Thus, in addition to (or instead of) chickens as a meat source, chickens may also be raised for their reproductive ability. Young females (young hens) may be raised to give off food or fertilized eggs after adulthood, and males (young cocks) may be raised to be used as breeders after adulthood. In these cases, their juvenile stage lasts much longer than broilers, typically up to about 16-20 weeks. Here, the "brood" illumination spectrum may be used for the first about 1-2 weeks, and the "grow" illumination spectrum may be used thereafter.
Furthermore, in an embodiment, pulsed illumination may be applied: for example, pulses of predefined "brood" lighting conditions may be used during the growth period (see also fig. 2 e). This may improve the activity and feeding of older birds. The light pulses may be stronger illumination conditions or different spectral components, or a combination of intensity and spectral components. When the pulse intensity is modulated, the inter-pulse interval may include low level illumination (e.g., 0.1-20 lux); the pulses may include higher intensity light (> 20 lux). In particular, in an embodiment, the brightness of the pulses may be at least 1.5 times the baseline intensity.
While the pulse spectral components may be modulated, the inter-pulse intervals may include a growth spectral component, as described with respect to fig. 2 e. The pulses will add red and green channels to match the "brood" channel, also depicted in fig. 2 e. The pulse length and inter-pulse spacing may remain constant throughout the photoperiod or may vary throughout the day. One example of a pulse schedule is a 1 hour pulse and a 3 hour pulse interval. The pulse duration may range from 5 minutes to 2 hours; the inter-pulse interval may range from 10 minutes to 6 hours.
Furthermore, in an embodiment, the invention allows for feedback based adaptive illumination. For example, the sensor may be used to detect a condition of an individual or group. Furthermore, in embodiments, the "brood" condition may be used longer if desired, or the "grow" condition may begin earlier if desired. In embodiments, the "brood" condition may be used briefly to increase the activity of the birds, even during the growth period. If the birds need to rest or wheeze, the "growing" condition may be used for a period of time during the brood time period.
The invention can be applied to chickens (including chickens). Other species/breeds may be turkeys, ducks, geese, pheasants, quails, guinea fowl. The term "chicken" may also refer to slow-growing broiler chickens or chickens of conventional varieties.
In embodiments, one or more additional illumination channels may be added.
For example, in an embodiment, an amber color may be added. In an embodiment, the amber spectrum may be defined as a light source having a spectral density output function that results in a maximum peak between 580nm and 620 nm. If an amber spectrum is included, in an embodiment, the relative intensity of this peak may also be approximately equal to the other peaks during the (+/-20%) brooding stage. In an embodiment, similar to the red channel, the amber light source light may be substantially completely removed during the growth phase.
Adding amber color may increase the color rendering index, allowing the birds to resolve a larger color gamut. Because the amber color has two components, red and green, it may be considered to be most red in the recipe definition. In an embodiment, during brooding, the amber color may be present at about equal intensity as the other channels, but during growth it may be desirable to substantially darken. In other embodiments, amber may be used to completely replace the red channel.
For example, in (other) embodiments, UV and/or deep blue light may be provided, such as for example UV-Sup>A. Uv-a light may produce a biological effect on poultry similar to blue: it appears to have sedative effects and appears to reduce stress. The control of the UV-Sup>A channel may be substantially similar to blue. In this context, the UV-Sup>A spectrum may be defined as Sup>A light source with Sup>A spectral density output function, which results in Sup>A maximum peak between 360nm and 400 nm. If UV-A is included, the relative intensity of this peak may also be approximately equal to the other peaks during the brooding phase (+/-20%). In an embodiment, the UV-Sup>A light source may remain substantially completely during the growth phase, substantially similar to the blue channel.
With respect to the transition between the "brood" and "grow" conditions, in embodiments, the transition between the "brood" and "grow" conditions may occur between about 10-20 days (post-hatch). In an embodiment, each peak intensity may be interpolated approximately linearly over 10 days, so there is no abrupt illumination spectrum change every day. In alternative embodiments, the transition may occur up to 40 days or as short as 1-2 days.
Several experiments were performed, see below.
Brooding test
A test was performed to compare the growth rate and Feed Conversion Rate (FCR) of broilers raised under conventional white light with the illumination schemes outlined in the present disclosure. Five 50 chicken rooms were assigned to one lighting treatment group, and five 50 chicken rooms were assigned to another lighting treatment group. Chickens were managed according to standard broiler management practices and chicken weight and consumed feed were measured. Feed Conversion Ratio (FCR) was determined by calculating the amount of feed consumed by each chicken divided by the weight of each chicken. The results for the 22 day old chicks are shown below:
White light light treatment 2 (invention) Improvements in or relating to
Average chicken weight 0.9912kg 1.0088kg 0.0176kg(1.8％)
Average FCR 1.671 1.630 4.1 percentage points
Combined brood+growth test
An experiment was performed to compare the growth rate and Feed Conversion Rate (FCR) of broilers raised and grown under two different lighting conditions. In illumination process #1, as the light darkens, the red light darkens completely. In illumination process #2, the red light is also darkened, but the green light is also darkened by half during the darkening process. Illumination process #2 represents the invention outlined in this disclosure, conventional white light, and the illumination scheme outlined in this disclosure. Five 50 chicken rooms were assigned to one lighting treatment group, and five 50 chicken rooms were assigned to another lighting treatment group. Birds were managed according to standard broiler management practices and birds weight and consumed feed were measured. Feed Conversion Ratio (FCR) was determined by calculating the amount of feed consumed by each chicken divided by the weight of each chicken. The results of the birds at the end of the test are shown below:
light treatment 1 Light treatment 2 (invention) Improvements in or relating to
Average bird weight of 42 days 2.8164kg 2.8470kg 0.0306kg(1.1％)
Average FCR 1.763 1.756 0.7 percentage points
Further test
One broiler farm was used to test the performance of birds given traditional white light with the lighting schemes outlined in this disclosure. The same house with matched flock-derived chickens was used between the control groups. Each house was placed with approximately 11000 birds and managed according to standard broiler management practices. Feed Conversion Ratio (FCR) was determined by calculating the amount of feed consumed by each chicken divided by the weight of each chicken. The results of the three rounds of testing are shown below:
FCR white light FCR, the invention FCR improvements
Test 1 1.63 1.57 6 percentage points
Test 2 1.782 1.652 13 percentage points
Test 3 1.783 1.724 5.9 percentage points
In yet another test, an isolation test, an appearance test (emergence test) and a tonic immobility test were performed according to the light recipe. In addition, the ratio of the eosinophils was tested according to the light formulation. The control group received light with no change in the blue-green ratio, and the test group received light according to the schedule described herein. All tests showed that the test group had better results than the control group.
