[0026] As Figures 1-5As shown, a plant tissue culture illuminating device includes a housing 1, a plurality of LED lamp panels 8 are equidistantly arranged inside the housing 1, mounting blocks 14 are symmetrically fixed on the front and back sides of each LED lamp panel 8, a plurality of U-shaped pieces 13 are equidistantly fixed on the front and back sides of the inner wall of the top of the housing 1, the U-shaped pieces 13 and the mounting blocks 14 are detachably connected through an elastic clamping shaft structure, an electric contact ring 21 is equidistantly fixed on the inner wall of the top of the housing 1, an electric contact shaft 22 is fixed on the top of the LED lamp panel 8, the electric contact ring 21 and the electric contact shaft 22 form a power circuit, and the electric contact ring 21 is electrically connected with an external power supply.

[0027] In this way, firstly, the LED lamp panel 8 is detachably connected through the elastic clamping shaft structure between the mounting block 14 and the U-shaped piece 13, which can conveniently add or reduce the LED lamp panel 8, so as to not only flexibly adjust the illumination range and intensity, but also accurately and flexibly adjust the spectrum, so that the illuminating device can fully meet the needs of various plant tissue culture, thereby not only improving the versatility and applicability of the device, but also reducing the cost of purchasing multiple lighting equipment to meet different culture needs.

[0028] Secondly, the electric contact ring 21 equidistantly fixed on the inner wall of the top of the housing 1 matches the electric contact shaft 22 fixed on the top of the LED lamp panel 8, thereby providing stable circuit connection for each LED lamp panel 8, so as to not only ensure that each lamp panel can normally work in the process of multi-lamp panel expansion, but also avoid the problem that part of the lamp panel does not light or flickers due to unstable circuit connection, thereby ensuring the stability and continuity of the light in the process of plant tissue culture.

[0029] Thirdly, when a certain LED lamp panel 8 fails, since the electric contact ring 21 and the electric contact shaft 22 are designed to match, the lamp panel only needs to be disassembled, without affecting the normal work of other lamp panels, thereby greatly improving the efficiency of maintenance and repair.

[0030] The LED lamp panel 8 adopts a mature existing technology product on the market, which can be directly obtained by procurement, and its working principle based on a specific chip driving light emission and a conventional installation method suitable for various illuminating devices have been mastered by those skilled in the art, so in this embodiment, the working principle and installation method of the LED lamp panel 8 will not be described in detail.

[0031] The electric contact ring 21 and the electric contact shaft 22 are mature existing technology products on the market, which can be directly obtained by procurement, and their working principle and installation method have been mastered by those skilled in the art, so in this embodiment, the working principle and installation method of the electric contact ring 21 and the electric contact shaft 22 will not be described in detail.

[0032] The elastic clamping shaft structure comprises clamping holes 15 symmetrically arranged on the two side walls of the mounting block 14, clamping shafts 16 matched with the clamping holes 15 are slidably connected to the two sides of the U-shaped piece 13, ear pieces 17 are symmetrically fixed to the two sides of one end of the two clamping shafts 16 away from each other, slide shafts 18 are slidably connected to the ear pieces 17, one end of the slide shaft 18 is fixedly connected to the U-shaped piece 13, and a spring 19 is sleeved on the slide shaft 18, and the two ends of the spring 19 are connected to the U-shaped piece 13 and the ear piece 17 respectively.

[0033] In this way, firstly, the close fit of the clamping shaft 16 and the clamping hole 15, as well as the continuous elastic force provided by the spring 19, keep the LED lamp plate 8 and the U-shaped piece 13 firmly connected, so that even if the device is slightly shaken or affected by external force during operation, the buffering effect of the spring 19 can effectively prevent the clamping shaft from loosening and falling off, ensuring that the LED lamp plate 8 is always in a stable working state, avoiding the interruption of lighting or damage to the equipment caused by unstable connection, and providing a reliable lighting environment for plant tissue culture.

[0034] Secondly, when disassembling, the ear piece 17 is pinched and pulled outward, driving the clamping shaft 16 to be pulled out of the clamping hole 15, and at the same time stretching the spring 19 to generate elastic force, so that the lamp plate can be removed; when installing, the spring 19 pushes the clamping shaft 16 to automatically clamp into the clamping hole 15 after the alignment part is released, completing the fixation, so that the entire disassembly or installation process does not need to rely on any additional tools and can be completed completely by human power, which is simple and intuitive, greatly improves the work efficiency, and meets the needs of rapid adjustment and maintenance of the lighting device.

[0036] In this way, firstly, the light shielding plate 2 arranged around the outer wall of the shell 1 can effectively block the light scattered to the surrounding by the lighting device, avoiding interference to the surrounding areas that do not need light, and ensuring that the plant tissue receives appropriate light irradiation in a specific light range, thereby optimizing the lighting environment for plant tissue culture and being beneficial to improve the culture effect.

[0037] Secondly, the T-shaped groove 9 on the top outer edge of the shell 1 corresponds to the T-shaped piece 10 of the light shielding plate 2, so that the T-shaped piece 10 can be pushed into the T-shaped groove 9 for installation, which is convenient and stable and not easy to loosen and fall off; when maintaining and replacing the light shielding plate 2, the T-shaped piece 10 can be easily removed by pulling it out, and after maintenance, it can be installed back according to the original steps, which reduces the cost and ensures that the lighting device provides a stable lighting environment for plant tissue culture for a long time.

[0038] The shell 1 is provided with a mounting bracket 3 above, and threaded shafts 11 are fixed to the top corners of the shell 1.

The second lifting rings 6 are fixedly provided with internally threaded sleeves 12 matched with the threaded shafts 11.

[0039] In this way, first, the distance between the first lifting rings 4 and the second lifting rings 6 can be conveniently changed through the adjustable length connecting pieces 5, so as to adjust the height of the lighting device shell 1, and then the different requirements of plants at different stages in the plant tissue culture process for light intensity and distance can be adapted.

The device can adapt to various mounting brackets containing the first lifting rings 4, improve the universality, reduce the cost of customizing special equipment, and can be widely used in various plant tissue culture scenes.

[0042] In this embodiment, the connecting piece 5 is a 304 stainless steel wire rope.

The elastic property ensures that they are always in close contact, stabilizes the circuit connection, eliminates the conditions such as non-lighting, flickering or unstable power of the LED lamp panel 8 due to poor contact, and ensures stable plant lighting to help normal growth of plants.

[0046] Secondly, when the scale of plant tissue culture changes and the number of LED lamp panels 8 needs to be increased or decreased, the installation positions of the electric contact shafts 22 and the electric contact rings 21 of different lamp panels may be deviated. The deformability of the elastic conductive material can automatically adapt, and no matter how the lamp panel is adjusted, it can ensure good conduction between each electric contact shaft 22 and the corresponding electric contact ring 21, smoothly connect the new lamp panel, and the original lamp panel is not disturbed, which improves the expandability and adaptability of the device.
