Description

Technical Field

[0001] This utility model belongs to the field of microalgae cultivation technology, specifically relating to a microalgae lamp and cultivation device. Background Technology

[0002] Microalgae require light to complete their growth cycle. Therefore, in microalgae cultivation experiments, lamps are usually placed inside the culture dish. Current methods involve directly placing multiple lamp strips inside the culture dish. These lamp strips include a lamp housing and linear, flexible, or ribbon-like lights housed within it. Due to their small size, heat sinks cannot be installed, resulting in low power and low luminous efficiency, failing to provide sufficient light energy and thus affecting microalgae growth and experimental results.

[0003] Some microalgae lamps integrate multiple light strips, increasing light intensity and providing sufficient illumination for microalgae growth. These lamps can be placed directly in the culture medium of the petri dish, shortening the distance between the light source and the culture medium, reducing light energy loss, and allowing for higher wattage lamps. However, these lamps typically incorporate waterproof sealing structures and lenses. These features not only increase manufacturing difficulty and the number of components, resulting in a more complex structure, but the lenses also cause light loss, leading to wasted light energy and energy consumption. Furthermore, the heat emitted by the lamp is directly transferred to the culture medium, causing the culture medium temperature to rise, affecting the normal growth environment of the microalgae and leading to inaccurate experimental data.

This invention directly mounts the light source plate on the heat sink, eliminating the need for sealing structures and lenses, thus reducing manufacturing difficulty and the number of components. The structure is simple, and the light emitted by the LEDs on the light source plate can directly illuminate the culture medium without the distortion caused by lenses, significantly reducing light energy loss and saving energy.

[0029] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0030] Example 1

[0031] like Figures 1-4 As shown, this embodiment provides a microalgae lamp, including a connector and several light source mechanisms 10. The connector includes a first connector 20 and a second connector 30. The two ends of the several light source mechanisms 10 are respectively connected to a first connector and a second connector 30. The light source mechanism 10 includes a light source plate 1 and a heat dissipation assembly. The heat dissipation assembly includes a heat dissipation plate 21 and a heat dissipation strip 22. The light source plate 1 is disposed on the outer side of the heat dissipation plate 21, and the heat dissipation strip 22 is disposed on the inner side of the heat dissipation plate 21. The first connector 20 is connected to one end of the heat dissipation plate 21, and the second connector 30 is connected to the other end of the heat dissipation plate 21.

[0032] The light source board 1 and the heat sink 21 can be bonded together by means of adhesive or other methods, so that the light source board 1 and the heat sink 21 are fully bonded, which is conducive to better heat dissipation.

[0033] Example 2

[0034] like Figures 1-4As shown, this embodiment provides a microalgae lamp, including a connector and several light source mechanisms 10. The connector includes a first connector 20 and a second connector 30. The two ends of the several light source mechanisms 10 are respectively connected to a first connector and a second connector 30. The light source mechanism 10 includes a light source plate 1 and a heat dissipation assembly. The heat dissipation assembly includes a heat dissipation plate 21 and a heat dissipation strip 22. The light source plate 1 is disposed on the outer side of the heat dissipation plate 21, and the heat dissipation strip 22 is disposed on the inner side of the heat dissipation plate 21. The first connector 20 is connected to one end of the heat dissipation plate 21, and the second connector 30 is connected to the other end of the heat dissipation plate 21.

[0035] In this design, both the first connector 20 and the second connector 30 are regular polygons; several light source mechanisms 10 are arranged at intervals along the circumference of the connectors. This facilitates the installation of the microalgae lamp inside the culture body 6 and also avoids heat transfer between the light source mechanisms 10. The cross-sectional shape of both the first connector 20 and the second connector 30 is a regular polygon. The regular polygonal design of the connectors allows the edges of the connectors to better fit and connect with the heat sink 21, improving the stability and reliability of the connection. The number of sides of the connectors corresponds one-to-one with the number of light source mechanisms, ensuring that the light source mechanisms 10 are evenly distributed around the circumference of the connectors, thereby emitting light evenly in all directions. This ensures that the culture placed around the microalgae lamp receives uniform light irradiation, guaranteeing the accuracy of experimental data and thus ensuring the reliability of the experimental results.

[0036] The light source plate 1 is equipped with LEDs of different color temperatures. These LEDs include low-color-temperature LEDs and high-color-temperature LEDs, which are alternately arranged to ensure uniform light distribution. Existing microalgae lamps can only emit light of one color temperature, resulting in a limited color range that cannot adequately meet the light color requirements of different growth stages. This invention, by using LEDs of different color temperatures, allows for the use of different LEDs according to different growth stages of microalgae, better simulating different growth environments, ensuring the accuracy of experimental data, and thus guaranteeing the reliability of experimental results.

[0037] The light source mechanism 10 further includes a dimming mechanism for adjusting brightness, which is connected to the light source plate 1. The dimming mechanism is a dimmer. A dimmer is an electrical device used to change the luminous flux of the light source in the lighting device and adjust the illuminance level. It can control the on / off frequency of the light source plate 1, better simulate different growth environments of microalgae, meet the growth needs of different growth stages, ensure the accuracy of experimental data, and thus ensure the reliability of experimental results.

[0038] The light source mechanism 10 further includes a water-blocking component 40, which is disposed on the outer side of the heat sink 21 and above the light source plate 1. The water-blocking component 40 includes a water-blocking plate 3 and a flow-intercepting plate 4, with the flow-intercepting plate 4 disposed on the outer edge of the water-blocking plate 3. The water-blocking component 40 is designed to prevent liquid from getting onto the heat sink 21 and flowing down the heat sink 21 to the light source plate 1 during feeding or other operations on the microalgae.

[0039] Both the baffle plate 3 and the light source plate 1 are located on the outer side of the heat sink 21. The baffle plate 3 is located at the top of the heat sink 21, and the light source plate 1 is located at the bottom of the heat sink 21. Water falls from above onto the heat sink 21 and flows downward along the outer side of the heat sink 21. When it encounters the baffle plate 3, it falls onto the baffle plate 3, preventing water from falling onto the light source plate 1. The heat sink 21 is located on the inner edge of the baffle plate 3. To prevent water from flowing out from the outer edge of the baffle plate 3, this invention also provides a flow interceptor plate 4 on the outer edge of the baffle plate 3, thereby effectively blocking water.

[0040] The water baffle 3 includes a front water baffle 31 and a side water baffle 32. The front water baffle 31 is disposed on the outer side of the heat dissipation plate 21, and the side water baffle 32 is disposed on both sides of the outer side of the heat dissipation plate 21. The flow interceptor 4 includes a front flow interceptor 41 and a side flow interceptor 42, which are respectively disposed opposite to the front water baffle 31 and the side water baffle 32.

[0041] The side water-blocking part 32 allows water on the front water-blocking part 31 to flow through to both sides of the heat sink 21, preventing water from flowing along the sides of the heat sink 21 to the light source plate 1. Specifically, the side water-blocking part 32 is connected to the heat dissipation strip 22 on the inner side of the heat sink 21, guiding the water to the heat dissipation strip 22 and effectively preventing water from flowing to the light source plate 1. The front intercepting part 41 and the side intercepting part 42 correspondingly prevent water on the front water-blocking part 31 and the side water-blocking part 32 from flowing outwards, further serving as a water-blocking function and further preventing water from flowing to the light source plate 1.

[0042] Among them, a power supply frame 5 for installing power supply is provided between multiple light source mechanisms 10. The power supply is installed on the power supply frame 5 to facilitate the installation and connection of the light source mechanism 10.

[0044] like Figures 5-9As shown, a cultivation device includes a cultivation mechanism and a microalgae lamp as described in Embodiment 1 or Embodiment 2. The cultivation mechanism includes a cultivation body 6, which includes an outer side plate 62 and an inner side plate 61. The inner side plate 61 is made of a transparent material. The inner side plate 61 forms a light source cavity 63, and the microalgae lamp is disposed within the light source cavity 63. The outer side plate 62 is sleeved on the inner side plate 61, and the outer side plate 62 and the inner side plate 61 form a cultivation cavity 64. A predetermined distance is left between the light source plate 61 and the inner side plate 61. The transparent material is glass or acrylic, and the cultivation cavity 64 is sealed.

[0045] Example 4

[0046] like Figures 5-9 As shown, a cultivation device includes a cultivation mechanism and a microalgae lamp as described in Embodiment 1 or Embodiment 2. The cultivation mechanism includes a cultivation body 6, which includes an outer side plate 62 and an inner side plate 61. The inner side plate 61 is made of a transparent material. The inner side plate 61 forms a light source cavity 63, and the microalgae lamp is disposed within the light source cavity 63. The outer side plate 62 is sleeved on the inner side plate 61, and the outer side plate 62 and the inner side plate 61 form a cultivation cavity 64. A predetermined distance is left between the light source plate 61 and the inner side plate 61. The transparent material is glass or acrylic, and the cultivation cavity 64 is sealed.

[0047] The cultivation mechanism further includes a support frame 7 with an opening on the light source cavity 63. The support frame 7 includes several connecting strips 71 and positioning blocks 72. The two ends of the connecting strips 71 are connected to the positioning blocks 72 and the inner side plate 61, respectively. A light source mechanism 10 is provided between two adjacent connecting strips 71. The preset distance is 10-30cm. This preset distance refers to the distance obtained by subtracting the shortest distance from the light-emitting surface of the light source plate 1 to the center of the circle from the radius of the circle containing the cross-section of the light source cavity 63.

[0048] The inner side plate 61 forms a light source cavity 63, within which the microalgae lamp is located. The outer side plate 62 is fitted over the inner side plate 61, and the outer side plate 62 and the inner side plate 61 together form a culture cavity 63. The culture is arranged around the microalgae lamp, ensuring sufficient irradiation. Simultaneously, a predetermined distance is maintained between the light source plate 1 and the inner side plate 61, and between the light source plate 1 and the culture. This further facilitates comprehensive and sufficient irradiation of the culture by the light emitted from the light source plate 1. Furthermore, the microalgae lamp does not directly contact the culture, preventing heat transfer and ensuring the accuracy of experimental data.

[0049] The preset distance d is 10-30cm. More preferably, the preset distance d is 16-25cm. More preferably, the preset distance d is 18-22cm. More preferably, the preset distance d is 20cm. This range of preset distances ensures that the area illuminated by light is large and the light is sufficient, maximizing the utilization of light energy and reducing light energy waste, thus saving energy.

[0050] To effectively fix the microalgae lamp in the light source cavity 63, a support frame 7 is provided at the top of the culture body 6, i.e., the upper opening of the light source cavity 63. The two ends of the connecting strip 71 are connected to the positioning block 72 and the inner side plate 61 respectively, fixing the support frame 7 in the upper opening of the light source cavity 63. Each light source mechanism 10 passes between two adjacent connecting strips 71. That is, the two adjacent connecting strips 71 and the positioning block 72 cooperate to support and fix the light source mechanism 10, thus fixing the light source mechanism 10 inside the light source cavity 63. Its structure is simple and its installation is reliable.

[0051] The light source cavity 63 also has a lower opening, which facilitates the connection of wires and other components to the outside of the culture body 6. The culture body 6 is supported by a support base, allowing wiring to pass through the bottom of the culture body 6.

[0052] The light source cavity 63 has an upper light-shielding member 8 at its upper opening and a lower light-shielding member 9 at its lower opening. Both the upper light-shielding member 8 and the lower light-shielding member 9 have reflective elements on the side facing the light source cavity 63.

[0053] The upper light-shielding member 8 and the lower light-shielding member 9 are designed to prevent light from shining into the upper and lower openings, thus reducing light energy loss. The reflector is designed to reflect the light that shines on the upper light-shielding member 8 and the lower light-shielding member 9 into the light source cavity 63, further improving light utilization and reducing light energy loss.

[0054] The system also includes a circulation mechanism, which comprises a circulation tube 11 and a pump 12 mounted on the circulation tube 11. Both ends of the circulation tube 11 are connected to the culture chamber 64. The pump 12 draws the culture from one end of the culture chamber 64 to the other, thus causing the culture within the chamber to flow. Specifically, one end of the circulation tube 11 is connected to the top of the culture body 6, and the other end is connected to the bottom of the culture body 6. The culture is drawn from the bottom of the culture body 6 and then fed back in from the top.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
