[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0049] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0050] In order to further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following detailed description of this application is made in conjunction with the accompanying drawings and preferred implementation methods.

[0051] Photosynthetic organisms (such as plants and microalgae) have the ability to photosynthesize and can be widely used in the fields of medicine, energy, environment, food, etc. By cultivating and observing photosynthetic organisms in the laboratory, it is helpful to optimize the cultivation conditions of photosynthetic organisms. The present application provides a photosynthetic organism cultivation device for cultivating photosynthetic organisms in a laboratory scenario. On the one hand, the above-mentioned photosynthetic organism cultivation device can flexibly simulate different lighting conditions, which is conducive to meeting the personalized cultivation needs of different types of photosynthetic organisms; on the other hand, it can collect experimental data in real time, which is convenient for data recording and subsequent analysis.

[0052] Please also refer to Figure 1-Figure 4 The photosynthetic organism cultivation device 100 of the present embodiment includes a housing 10, a plurality of culture dishes 20, a plurality of illumination assemblies 30, a plurality of light guide assemblies 40, and a control circuit 50. The housing 10 defines a receiving space 11, and the culture dishes 20, illumination assemblies 30, light guide assemblies 40, and control circuit 50 are located within the receiving space 11. The control circuit 50 is electrically connected to each illumination assembly 30 and is configured to control the illumination light emitted by each illumination assembly 30. The plurality of light guide assemblies 40 are configured to diffuse and guide the illumination light emitted by the illumination assembly 30 into each culture dish 20, thereby illuminating the photosynthetic organisms within each culture dish 20.

[0053] The housing 10 includes a base plate 12, a top cover 13, and a support plate 14. The support plate 14 is connected between the base plate 12 and the top cover 13. The support plate 14 is a frame structure with a certain thickness (the thickness direction is defined as the direction from the base plate 12 to the top cover 13), which maintains a certain distance between the base plate 12 and the top cover 13. Thus, when the top cover 13 is engaged with the side of the support plate 14 away from the base plate 12, the base plate 12, the top cover 13, and the support plate 14 together enclose the aforementioned receiving space 11. The base plate 12, the top cover 13, and the support plate 14 are all made of light-shielding materials, thereby isolating the aforementioned receiving space 11 from ambient light.

[0054] The bottom plate 12 is a thin plate-like continuous structure with a smooth surface. The support plate 14 is provided with a plurality of mounting holes 141 (see FIG. Figure 3 The upper cover 13 is provided with a plurality of grooves 131 arranged at intervals on the surface facing the support plate 14 (see FIG. Figure 4 When the upper cover 13 is fastened to the support plate 14, the plurality of mounting holes 141 correspond one-to-one with the plurality of grooves 131. Each mounting hole 141 is used to mount a culture dish 20. When the upper cover 13 is fastened to the support plate 14, the end of the culture dish 20 in each mounting hole 141, facing away from the base plate 12, is located in the corresponding groove 131 of the mounting hole 141.

[0055] In this embodiment, 8 installation holes 141 are provided on the support plate 14 at intervals, and 8 grooves 131 are provided on the upper cover 13 at intervals. The 8 installation holes 141 are arranged in an array of two rows and four columns, and the spacing between each two adjacent installation holes 141 is equal. In this embodiment, each installation hole 141 is a circular hole with the same area. In this embodiment, each installation hole 141 is on the same horizontal plane, so that each culture dish is on the same horizontal plane when installed in the installation hole 141. The 8 grooves 131 are consistent in shape and arrangement with the 8 installation holes 141, and the area of each groove 131 may be slightly larger than the area of each installation hole 141. This application does not limit the number, shape, and arrangement of the installation holes 141 and the grooves 131. In the embodiment of the present application, each installation hole 141 may also have different shapes and sizes.

[0056] The number of culture dishes 20 is the same as the number of mounting holes 141. Each culture dish 20 is used to accommodate photosynthetic organisms for growth. Each culture dish 20 is made entirely of light-transmitting material, allowing the photosynthetic organisms within to receive light and facilitating observation of their growth. Opening the upper cover 13 allows for easy access to each culture dish 20.

[0057] The number of illumination assemblies 30 is identical to the number of culture dishes 20 and corresponds one-to-one. The number of light guide assemblies 40 is identical to the number of culture dishes 20 and corresponds one-to-one. In this embodiment, one culture dish 20, one illumination assembly 30, and one light guide assembly 40 are defined as a cultivation unit. Thus, the photosynthetic organism cultivation device 100 of this embodiment includes eight independent cultivation units. Each cultivation unit has substantially the same structure and function. In other embodiments of the present application, the photosynthetic organism cultivation device 100 may include multiple independent cultivation units with different structures and functions.

[0058] See also Figure 5 In this embodiment, in each cultivation unit: the culture dish 20 and the light guide component 40 are stacked, and the light guide component 40 is located between the base plate 12 and the culture dish 20; the illumination component 30 is arranged on the light guide component 40, and is used to emit illumination light toward the light guide component 40; the light guide component 40 is used to diffuse the illumination light and guide it into the culture dish 20 to illuminate the photosynthetic organisms growing in the culture dish 20.

[0059] In this embodiment, each illumination assembly 30 includes at least a first light source 31 and a second light source 32. The first light source 31 and the second light source 32 are configured to emit illumination light of different wavelengths. In this embodiment, one of the first light source 31 and the second light source 32 is configured to emit white light, and the other is configured to emit infrared light with a wavelength of 730 nm. In this embodiment, both the first light source 31 and the second light source 32 are light emitting diode (LED) arrays, each comprising a plurality of LEDs.

[0060] The present application does not limit the number of light sources and the wavelength of the illumination light in each illumination component 30. In other embodiments of the present application, the illumination component 30 may include multiple (greater than or equal to three) light sources, wherein at least two of the light sources emit illumination light having different wavelengths, or the wavelengths of the illumination light emitted by each light source may be different. In addition to the white light and infrared light described in this embodiment, the illumination light emitted by the light source may also be selected from, for example, blue light (wavelength 40nm0-500nm), red light (wavelength 600nm-700nm), green light (wavelength 500nm-600nm), far infrared light (wavelength 700nm-750nm), and ultraviolet light (wavelength 300nm-400nm).

[0061] In this embodiment, the first and second light sources 31, 32 have high power and generate a lot of heat. The illumination assembly 30 also includes two heat sinks 33, which are connected to the first and second light sources 31, 32, respectively, to dissipate heat from the first and second light sources 31, 32, respectively, to prevent overheating and malfunction of the first and second light sources 31, 32.

[0062] In this embodiment, each light guide component 40 includes a reflective sheet 41, a light guide plate 42 and a diffuser 43, which are stacked in sequence, wherein the diffuser 43 is closer to the culture dish 20 than the reflective sheet 41. The planar structure of the reflective sheet 41, the light guide plate 42 and the diffuser 43 is adapted to the shape of the culture dish 20. In this embodiment, the reflective sheet 41, the light guide plate 42 and the diffuser 43 have a roughly circular planar structure. The light sources in the illumination component 30 (including the first light source 31 and the second light source 32 in this embodiment) are spaced and symmetrically arranged along the circumference of the light guide plate 42. That is, the light sources in the illumination component 30 are arranged around the light guide plate 42. The light-emitting surfaces of the first light source 31 and the second light source 32 are in close contact with the side surfaces of the light guide plate 42.

[0063] In this embodiment, each light guide assembly 40 further includes a light sensor 44 electrically connected to a control circuit 50. A through hole 411 is defined in the reflective sheet 41. The light sensor 44 is located on the surface of the light guide plate 42 facing the reflective sheet 41 and within the through hole 411. When the first light source 31 and the second light source 32 emit illumination light, the light sensor 44 is configured to receive and sense the intensity of the illumination light emitted by the light guide plate 42 and to feed back the intensity information to the control circuit 50. The control circuit 50 is configured to control the luminous intensity of the first light source 31 and the second light source 32 based on this intensity information.

[0064] The illumination light emitted by the first light source 31 and the second light source 32 is incident on the light guide plate 42. The dotting method of the light guide plate 42 is low density at the edge and high density in the middle, which is conducive to uniform illumination light. When light tends to propagate toward the bottom, the reflective sheet 41 is used to reflect it back to the light guide plate 42 for reuse, which can effectively avoid the waste of light energy and help improve the utilization rate of light. The diffuser 43 is used to diffuse the illumination light from the light guide plate 42 and evenly emit it to the culture dish 20, so as to prevent the illumination light from directly hitting the photosynthetic organisms in the culture dish 20 and affecting their growth. In this way, the light guide assembly 40 in this embodiment is equivalent to a light source, which can emit illumination light with uniform intensity distribution toward the culture dish 20.

[0065] Please refer to Figure 3 In this embodiment, each light guide assembly 40 is disposed on the base plate 12. A control circuit 50 is disposed on the base plate 12 and electrically connected to the first light source 31 and the second light source 32 in each illumination assembly 30, respectively, for controlling the on / off state and luminous intensity of the first light source 31 and the second light source 32 in each illumination assembly 30. In at least one embodiment of the present application, the electrical connection between the control circuit 50 and the first light source 31 and the second light source 32 can be achieved by embedding wiring (not shown) in the housing 10.

[0066] By controlling the switching states and luminous intensities of the first and second light sources 31, 32 in each illumination assembly 30 through the control circuit 50, illumination with varying light qualities can be adjusted to illuminate the photosynthetic organisms within the culture dishes 20. Furthermore, in this embodiment, the housing 10 is constructed of a light-shielding material, and the multiple culture dishes 20 are spaced apart. This isolates the illumination light emitted by the illumination assemblies 30 within each cultivation unit, thus preventing crosstalk between the illumination light sources within the cultivation units. In other words, in this embodiment, the first and second light sources 31, 32 within each cultivation unit can be independently controlled to provide illumination with varying light qualities to each culture dish 20. This facilitates simultaneous observation of the growth of photosynthetic organisms under varying illumination conditions.

[0067] In natural environments, photosynthetic organisms such as plants and microalgae receive a full spectrum of sunlight. However, in artificial lighting conditions, such as greenhouses or indoor cultivation, specific wavelengths of light are often used to optimize the growth of photosynthetic organisms. For example, LED plant growth lights can adjust the intensity of different wavelengths of light to simulate natural sunlight or optimize the growth conditions of specific photosynthetic organisms.

[0068] The photosynthetic organism cultivation device 100 of the present application embodiment can be used for the early stage cultivation condition screening under the laboratory scene, and can also be used for the screening of mutant strains. Photosynthetic organisms mainly use the light in the visible spectrum (approximately between 380 and 700 nanometers) to photosynthesize. However, some photosynthetic organisms can use the ultraviolet (UV-A and UV-B) or infrared (near infrared) part of the spectrum. For these organisms, their pigment complexes or pigment-binding proteins may have different spectral absorption characteristics, enabling them to utilize light energy outside the visible spectrum. By combining ultraviolet or infrared light, it can be used to screen mutants of this type for subsequent synthetic biology chassis cells.

[0069] Therefore, the photosynthetic organism cultivation device 100 of the present embodiment, by controlling the on / off and luminous intensity of the first light source 31 and the second light source 32 in each illumination assembly 30 by the control circuit 50, can provide each culture dish 20 with illumination of different light qualities, thereby simulating various illumination conditions and observing the growth of photosynthetic organisms within the culture dish 20 under various illumination conditions, thereby screening for optimal illumination conditions for specific photosynthetic organism species. Furthermore, the photosynthetic organism cultivation device 100 can adjust illumination of different light qualities for different photosynthetic organism species, thereby making the photosynthetic organism cultivation device 100 applicable to the cultivation of a variety of different photosynthetic organism species.

[0070] The photosynthetic organism cultivation device 100 of this embodiment also includes a fan 60 located in the receiving space 11 and a temperature sensor 70 connected to the bottom plate 12 of the housing 10. The control circuit 50 is electrically connected to the fan 60 and the temperature sensor 70 respectively. Two vents 142 arranged opposite to each other are also provided on the side of the support plate 14. The temperature sensor 70 is used to detect the current room temperature in real time. The control circuit 50 is used to receive the room temperature data sent back by the temperature sensor 70, feedback-adjust the speed of the fan 60, and cooperate with the vents 142 to allow air to flow, thereby cooling the receiving space 11 and making the temperature in the receiving space 11 approach the current room temperature, thereby effectively preventing overheating from causing abnormalities in the illumination component 30.

[0071] The photosynthetic organism cultivation device 100 of this embodiment also includes a WIFI module 80 located within the receiving space 11. The WIFI module 80 is electrically connected to the control circuit 50 and can transmit the experimental data collected by the photosynthetic organism cultivation device 100 to a remote terminal device (such as a smartphone, host, tablet computer, etc.). This facilitates remote and timely access to data from the photosynthetic organism cultivation device 100 through the terminal device. By operating on the corresponding page of the terminal device, the operation of each functional module within the photosynthetic organism cultivation device 100 (including the lighting component 30, fan 60, etc.) can also be remotely controlled. In this embodiment, the photosynthetic organism cultivation device 100 also includes a power interface 143 for plugging in an external power supply, which is located on the support plate 14 and is connected to the control circuit 50.

[0072] Therefore, the photosynthetic organism cultivation device 100 of the embodiment of the present application can collect and send the experimental data of the photosynthetic organism cultivation device 100 in real time by setting the WIFI module 80, which is conducive to timely storage of data and subsequent data analysis, and is conducive to remote monitoring and control of the operating status of the photosynthetic organism cultivation device 100 (including the switch of the first light source 31 and the second light source 32, the luminous intensity, the speed of the fan 60, the real-time room temperature, etc.), thereby realizing the Internet of Things control function.
