Such devices include, for example, setting up a lighting laboratory filled with light sources, placing animals in the environment filled with irradiation light for irradiation experiments. However, similar devices require a large experimental space and cannot accurately verify the effectiveness of the experiment. Moreover, the formation of such an environment filled with light often requires more light sources, which will also generate higher energy consumption during use and result in higher production and use costs.

[0003] In view of this, there is an urgent need to provide an irradiation system solution so that irradiation experiments can be carried out stably and at low cost. Utility Model Content

[0030] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0031] Figure 1The schematic diagram of the principle of some existing irradiation systems is shown. In some existing irradiation systems, animals are usually irradiated only with the cooperation of a point light source and a plane diffuser. Among them, since the light of a point light source is generally emitted radially, the distribution of the light of the light source on the diffuser is uneven, that is, the central part closer to the light source has a higher brightness, while the part farther from the light source has a lower brightness. And because the distances between each part of the diffuser and the animal to be irradiated are different, the scattered light on the diffuser is also uneven when irradiating the animal, that is, the brightness is weaker at a distance from the animal, and the brightness is stronger at a distance from the animal.

[0032] See also Figure 2 and Figure 3 , Figure 2 A schematic diagram showing the basic structure of an illumination system according to some embodiments of the present disclosure. Figure 3 A schematic diagram of the positional relationship between the irradiation system and the animal in some embodiments of the present disclosure is shown. The irradiation system in the present disclosure is used to perform experimental light irradiation on a target animal 40, so as to study and verify the effect of light therapy. The irradiation system can be set on a laboratory table 100, for example. The target animal 40 to be irradiated is set on a fixture 30 for fixing the animal 40, and the light emitting device 10 can be set on one side of the fixture 30, and its light emitting direction is facing the animal 40 on the fixture 30. The light emitting device 10 can include a light source mounting seat 11, which can be mounted on a fixing member 90, and the light source mounting seat 11 has an inner wall 110 formed in a hemispherical shape. A plurality of light sources 12 are arranged on the inner wall 110, and the plurality of light sources 12 are evenly spaced and arranged on the hemispherical inner wall 110, so that the light emitting parts of the plurality of light sources 12 together form a light source sphere 15, and the center of the light source sphere 15 is set to aim at the animal 40 to be irradiated. A light homogenizing device 20 in the shape of a hollow hemisphere may also be provided on the inner side of the light source mounting seat 11. The light homogenizing device 20 is concentric with the spherical surface of the light source 15 so that the distance between each position on the light homogenizing device 20 and the animal 40 to be irradiated is consistent, thereby being able to scatter the light emitted by multiple light sources 12 and evenly transmit it to the animal 40 to be irradiated.

[0033] Thus, the animal to be irradiated can receive the irradiation of light from multiple different three-dimensional angles from the spherical surface of the light source, and the irradiation light from each angle converges at the animal to be irradiated and is evenly distributed on the animal's body surface. Therefore, the irradiation system has lower requirements on the light intensity of a single light source, and a stable experimental effect can be obtained without using a lighting laboratory full of light sources. At the same time, multi-angle illumination also avoids the generation of blind spots in the experiment, so that the experimental results are accurate and reliable, and can be accurately verified. In addition, in order to evenly irradiate the animal, the actual size of the light-emitting device 10 can be determined according to the size of the animal that actually needs to be irradiated, and the size of the animal's body area that needs to be irradiated. The size of the light-emitting device 10 relative to the animal can be based on the light emitted by each light source on the light-emitting device 10 can be evenly irradiated on the animal's irradiated part. For easy installation and space saving, the light-emitting device 10 can be formed into a partial spherical shape such as a hemispherical shape, or a spherical shape that is less than one-third of a hemispherical surface.

[0034] See also Figure 4, which shows a three-dimensional schematic diagram of the light-emitting device of the illumination system of some embodiments of the present disclosure. It includes a light source mounting seat 11 that is formed as a whole in a hemispherical shape, and a plurality of light sources 12 that are spaced apart from each other and evenly arranged are arranged on the hemispherical inner wall 110 of the light source mounting seat 11. In this embodiment, a plurality of mounting holes are arranged on the light source mounting seat 11, and each mounting hole is used to install a corresponding light source 12. The fixing part of the light source 12 can be fixed in the mounting hole by bonding, for example, so that the light-emitting part of the light source 12 is exposed from the inside of the light source mounting seat 11. The plurality of light sources 12 can be formed into a plurality of circular rings with diameters from small to large, and the plurality of circular rings are arranged on the inner wall 110 of the light source mounting seat 11 in a mutually nested manner. Specifically, starting from the central part of the spherical surface of the inner wall 110, a plurality of light sources 12 form a plurality of circular rings whose diameters are arranged one by one in a nested manner from small to large, wherein the diameter difference between two adjacent circular rings is fixed, and the distance between adjacent light sources 12 in each circular ring is also the same, which makes the number of light sources 12 per unit area on the spherical surface roughly equal, ensuring that the light emitted from each angle by the plurality of light sources 12 on the light source mounting seat 11 is equal. Those skilled in the art will appreciate that, under the premise of ensuring that the number of light sources 12 per unit area on the inner wall 110 is roughly equal, the present disclosure does not restrict the arrangement of the light sources 12. According to the technical solution of the present disclosure, the arrangement of the plurality of light sources 12 needs to satisfy the formation of a spherical surface, that is, the plurality of light sources 12 are spatially distributed at a plurality of light source positions that are equidistant from a fixed point (center of the sphere), and the plurality of light source positions are not in the same plane or aspherical surface. A plurality of light source fixing members 111 protruding radially outward are further provided at the circumferential outer edge of the light source mounting seat 11, and the light source fixing members 111 are used to fix the light source mounting seat 11 to a fixed object, such as a rack or a laboratory table, etc. In this embodiment, the light source fixing members 111 can be provided as four rectangular fixing plates protruding from the outer edge of the light source mounting seat 11, and each rectangular fixing plate is provided with two through holes 112 for bolts to pass through.

[0035] In addition, a camera 13 is also provided on the inner wall 110 of the light source mounting seat 11, and the camera 13 is also arranged in the direction of the animal 40 to be irradiated, and is used to record the reaction of the animal 40 to be irradiated in the experimental process in real time through images, so as to facilitate the statistical study of subsequent experimental data. It can be understood by those skilled in the art that when it is necessary to observe and record the state of the experimental animal 40 from multiple angles, multiple cameras can be set, and each camera is arranged at a different position of the light source mounting seat 11, and it is only necessary to ensure that the lens direction of the camera is aimed at the experimental animal 40. In addition, an angle-adjustable camera can also be provided to further meet different recording requirements.

[0036] See also Figure 5, which shows a cross-sectional schematic diagram of a light emitting device of an irradiation system of some embodiments of the present disclosure. In addition to the above-mentioned light source mounting seat 11, multiple light sources 12 mounted thereon, and camera 13, the light emitting device 10 in this embodiment may also include a light homogenizing device 20 disposed inside the light source mounting seat 11. The light homogenizing device 20 is disposed along the light path on the side of the light emitting device 10 facing the animal to be irradiated, and the light homogenizing device 20 is used to scatter the light emitted by the light source 12.

[0037] The light-equalizing device 20 may include a light-equalizing plate body 21 that is roughly formed into a hollow hemispherical shape, and a light-equalizing plate fixing part 22 that is arranged at the circumferential outer edge of the light-equalizing plate body 21. Among them, the light-equalizing plate body 21 of the light-equalizing device 20 is roughly concentrically arranged with the light source sphere composed of the light-emitting parts of multiple light sources 12. The light-equalizing plate body 21 is used to scatter light, and its material may be, for example, frosted glass or other materials that scatter the transmitted light. The light-equalizing plate body 21 can be directly formed into a hollow hemispherical whole, but in order to save manufacturing costs, in some embodiments, the light-equalizing plate body 21 can also be composed of multiple arc-shaped light-equalizing sheets 211. In some embodiments, the light-equalizing plate body 21 is composed of 6 light-equalizing sheets 211. In addition, a camera hole corresponding to the position of the camera 13 on the fixing seat of the light source 12 can also be provided on the light-equalizing device 20, so that the lens of the camera 13 can be exposed therefrom.

[0038] See also Figure 6 , which shows a partial cross-sectional schematic diagram of the light homogenizing device of the illumination system of some embodiments of the present disclosure. Among them, the light homogenizing plate fixing part 22 of this embodiment is formed in a ring shape, and an annular groove 212 concentric with the main body of the light homogenizing plate fixing part 22 is formed on one axial end face thereof. The annular groove 212 penetrates into the interior of the light homogenizing plate fixing part 22 along an inclined angle, so that the annular groove 212 extends radially outward as the depth of its penetration into the light homogenizing plate fixing part 22 increases. The outer edge of the light homogenizing plate main body 21 can be embedded in the annular groove 212 for fixation, and can also be further fixed by bonding it to the inner side wall of the annular groove 212. In addition, for ease of installation, the cross section of the annular groove 212 can be set to have a wedge shape, that is, the side of the cross section of the annular groove 212 close to the surface has a larger groove width than the side that penetrates into the interior of the light homogenizing plate fixing part 22, which makes it easier to insert the edge of the light homogenizing plate main body 21. In this embodiment, an axially penetrating mounting through hole 213 is further provided on the radial outer side of the light homogenizing plate fixing member 22 . The mounting through hole 213 is used for inserting bolts to be mounted to the light source fixing member 111 of the light source mounting seat 11 .

[0039] See also Figure 7 and Figure 8 , Figure 7A schematic diagram showing the light emitting principle of a light emitting device of an illumination system of some embodiments of the present disclosure is shown, Figure 8 A schematic diagram of the positional relationship between the light-emitting device and the animal to be irradiated of the irradiation system of some embodiments of the present disclosure is shown. Among them, the light emitted by the multiple light sources 12 arranged on the inner wall 110 of the light source mounting seat 11 is evenly irradiated to the outer surface of the light-homogenizing device 20 facing the inner wall 110, and the light-homogenizing device 20 then scatters the light, so that it is transformed from a relatively concentrated point light source into a soft light spot. Furthermore, the light scattered by the light-homogenizing device 20 is emitted along the inner side of the hemispherical light-homogenizing device 20, and irradiated toward the center 101 of the spherical surface of the light source. The position of the animal 40 to be irradiated is aligned with the position of the center 101. As a result, the animal 40 to be irradiated can receive concentrated and evenly distributed light, and the light is soft, which avoids the excessive power caused by the light gathering at a certain point.

[0040] In some embodiments, a power module for providing energy for the irradiation system and a control system for controlling the illumination and the camera may also be included. The power module and the control system are electrically connected to the multiple light sources and the camera, respectively, to control the opening and closing of the lights. Furthermore, the control system may be set so that the control system can automatically control the switching of the light source according to the set time, or control the intensity of the light by switching a certain number of light sources. In addition, in some embodiments, the multiple light sources used for the irradiation system may be red light sources, so as to utilize their strong penetrability and other characteristics to conduct targeted experiments. In addition, it will be understood by those skilled in the art that although the present disclosure provides a design scheme for setting a light averaging device in the light source device, in some cases where it is not necessary to scatter the light of the light source, the light averaging device may not be set, and the light emitting parts of the multiple light sources together form the center of the light source sphere directly aligned with the target animal.

[0041] According to the illumination system of the embodiment of the present disclosure, the light emitting parts of multiple light sources are arranged at intervals to form a light source sphere, and the animal to be illuminated is placed at the center of the light source sphere, so as to ensure that the light power irradiated to the animal from all angles of the light emitting device is the same, ensuring the balance of light power. And under the premise of achieving the same illumination effect, the light of the illumination system is more concentrated, which not only reduces the number of light sources used, but also reduces energy consumption, and reduces production and use costs. At the same time, it has a simple structure, small size, convenient assembly, high stability, and is conducive to providing stable and low-error experimental data.

[0042] See also Fig. 9, which shows a three-dimensional schematic diagram of an animal experiment device of some embodiments of the present disclosure. Among them, the animal experiment device is composed of an irradiation system and a fixing device 30. The irradiation system includes a light-emitting device 10 and a fixing bracket 50. The light-emitting device 10 includes a light source mounting seat 11, a plurality of light sources 12 arranged on the light source mounting seat 11, and a light-averaging device 20 fixed on the light source mounting seat 11. The fixing device 30 can be, for example, a fixing seat equipped with a belt or other fixing mechanism, which is used to fix the animal to be irradiated. The fixing bracket 50 can be formed into a frame body by splicing metal profiles. The light-emitting device 10 is fixed to a vertical side of the fixing bracket 50 through a light source fixing piece 111 on the light source mounting seat 11, and the fixing device 30 is arranged on the side of the light source sphere 15 of the irradiation system facing the center of the sphere according to the light-emitting direction of the light-emitting device, so that the animal on the fixing device 30 is aligned with the center of the light source sphere composed of the light-emitting parts of the plurality of light sources 12 in the light-emitting device 10. The positions of the fixing device 30 and the irradiation system are relatively fixed. For example, the fixing device 30 and the fixing bracket 50 of the irradiation system can be fixedly installed on a laboratory table to ensure that the light emitted by the fixed light-emitting device can be aligned with the expected position of the animal to be irradiated on the fixing seat.

[0043] When using the animal experiment device disclosed in the present invention to conduct a lighting experiment, the animal can first be fixed with the aid of a fixing device 30 with a belt or other mechanism, so that the fixed animal is aligned with the center of the light source sphere 15 of the light-emitting device 10, and then the multiple light sources 12 of the illumination system are started for illumination. During the illumination process, the light emitted by the multiple light sources on the light source sphere 15 of the illumination system converges toward the center of the sphere and illuminates the animal from different three-dimensional angles. In some embodiments, the illumination system may include a camera 13 disposed on the inner wall 110 of the light source mounting seat 11 to record the animal's reaction during the lighting experiment. In addition, the illumination system may also include a light-homogenizing device 20 disposed between the light source and the animal, which scatters the light emitted by the light source to make the light irradiated to the animal softer and reduce the stimulation to the animal.
