Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically to an energy-saving and environmentally friendly LED lamp. Background Technology

[0002] Currently, environmentally friendly and energy-saving LED lights are being used more and more widely in agricultural greenhouses, replacing traditional fluorescent lamps and incandescent lamps. Compared with traditional light sources, LED lights have higher luminous efficacy, longer lifespan, lower energy consumption, and better color reproduction capabilities.

[0003] However, current agricultural greenhouse lighting control systems still have some problems. Most agricultural greenhouses can only achieve continuous illumination and shutdown, and cannot adjust the light according to the growth pattern of crops, nor can they simulate day and night changes. This is especially true in some areas with extreme polar night phenomena, such as the Nordic countries within the Arctic Circle (Norway, Finland, Sweden, etc.), northern Russia, northern Canada, and Greenland. In these areas, where the daylight hours are zero, agricultural planting is impossible without artificial light sources. However, with the continuous development of artificial light source technologies such as LEDs, it is now possible to simulate day and night light conditions through artificial light sources during polar nights, so that crops can receive the necessary light and thus achieve agricultural planting.

[0004] Artificial light sources can control the intensity and duration of light according to the growth patterns and needs of crops, simulating the day-night cycle to ensure normal growth and development. The application of artificial light sources allows for the cultivation and production of some vegetables and fruits during polar nights. However, adjusting the lighting in greenhouses requires manually adjusting the intensity of LED lights by controlling the current output. In high-latitude regions, where the long light cycle in agricultural greenhouses necessitates human intervention, this requires significant labor costs and is prone to errors. Relying solely on circuit control is energy-intensive, leading to unnecessary resource waste and poor results, ultimately impacting crop growth. Furthermore, human adjustment is hampered by the fact that plant respiration and photosynthesis are affected by environmental temperature and light, and transpiration rates vary, making it impossible to dynamically adjust based on crop growth status and environmental conditions.

[0005] In view of this, and in response to the problems existing in current LED lights, the present invention provides an energy-saving and environmentally friendly LED light. Summary of the Invention

[0006] The technical problem to be solved by this invention is that plant respiration and photosynthesis are affected by environmental temperature and light, and the transpiration of plants varies. The same light can easily lead to enhanced plant respiration, thereby increasing the transpiration rate and causing the plant to lose water too quickly. Therefore, light intensity at different times needs to be regulated. However, manual control is not precise enough and has a long cycle, which is very labor-intensive. Automatic circuit regulation is also very energy-intensive.

[0007] Based on the above problems, the present invention provides the following technical solution:

[0008] An energy-saving and environmentally friendly LED light is provided, comprising a housing, a light-emitting element, a winding mechanism, an elastic plate, and a cleaning mechanism. The housing has a cylindrical structure. This cylindrical structure allows the light-emitting element to emit light through one end of the elastic plate, with the light gradually dimming as the elastic plate contracts, creating a gradual change in light intensity. Furthermore, when fully extended, the diffuse reflection effect of the elastic plate increases the room's brightness. The housing is also hollow, allowing the light-emitting element to be fixedly connected inside, thus reducing light intensity and achieving a day-night cycle. A winding mechanism is installed inside the housing and is slidably connected to the elastic plate. The elastic plate is a rectangular thin plate. The larger side of the elastic plate engages with the winding mechanism, ensuring sufficient space within the winding mechanism to retract the elastic plate. Because the elastic plate is a rectangular thin plate, the channel within the winding mechanism can easily slide and connect with the elastic plate while maintaining good airtightness. The winding mechanism receives heat generated by the light-emitting element and utilizes the pressure generated by the thermal expansion of the gas to allow the elastic plate to slide within the mechanism. A cleaning mechanism is fixedly installed at one end of the winding mechanism. This cleaning mechanism cleans the elastic plate during the operation of the winding mechanism, ensuring airtightness between the elastic plate and the winding mechanism. The light-emitting element is electrically connected to the control mechanism.

[0009] The housing includes an upper cover, a cylindrical body, and a lower cover; the cylindrical body is a hollow cylinder with an inner diameter that is one-third of the outer diameter, to provide sufficient space for the winding mechanism so that the elastic plate can be rolled up inside the cylindrical body, and the cylindrical body is made of polycarbonate.

[0010] Based on the ratio of one-third between the inner diameter and the outer diameter, the winding mechanism has sufficient space to retract the elastic plate during processing due to the length of the elastic plate. Since the elastic plate is rolled up inside the housing, it has a larger design space and can be stably retracted.

[0011] It is also worth mentioning that the shell is made of polycarbonate. Polycarbonate is a high-performance, transparent, and high-strength plastic material with excellent impact resistance, which can accommodate the repeated sliding of the elastic plate within the channel. Furthermore, polycarbonate has a high refractive index and light scattering properties. Since the light-emitting element is located within a hollow structure inside the shell, the light transmittance of polycarbonate can reach over 90%. Therefore, the light generated by the light-emitting element can be scattered from the shell through the high transmittance of polycarbonate. At the same time, due to the good diffuse reflection effect of polycarbonate, when the elastic plate is fully extended, the light generated by the light-emitting element can pass through the shell and achieve a good diffuse reflection effect after passing through the elastic plate.

[0012] The winding mechanism includes an inlet, a channel, a baffle, and an air chamber. The channel is spirally arranged within the housing around its central axis. This spiral arrangement allows for greater flexibility within the housing. Since the number of channels matches the number of elastic plates, the channels within the housing can be rationally allocated based on the number of elastic plates. The elastic plates are engaged within the channel via the inlet, allowing them to slide within the channel while sealing the gas, ensuring stable gas delivery to the air chamber. The elastic plates can slide while maintaining airtightness through a sealing element on the inner wall of the channel. The baffle is fixedly connected to the end of the channel, allowing the elastic plates to be locked in place during sliding. The baffle and the channel are sealed by a sealing element. The air chamber is fixedly connected to one side of the channel. The air chamber is a hollow cavity communicating with the channel and is used to hold expanding gas. The air chamber applies pressure directly to the elastic plates through thermal expansion.

[0013] The main characteristic that needs to be explained is that the air cavity can transfer heat generated by the light-emitting body during use to the gas in the hollow cavity structure. When the gas expands, the gas volume increases due to the fixed space, and the pressure in the air cavity increases. Since the elastic plate has a rectangular groove, the forces on all surfaces of the inner wall of the rectangular groove are the same. Since the entrance of the winding mechanism is equipped with a locking structure, the elastic plate can be controlled to slide in one direction. Therefore, the expansion of the gas can push the elastic plate.

[0014] The elastic plate includes an initial end, a telescopic end, and an extension end; the elastic plate is a rectangular thin plate, and a rectangular groove is provided on one side of the telescopic end. Multiple rectangular grooves are linearly arranged along the side of the elastic plate. A blocking block is provided at the initial end, which is used to fix the elastic plate in the channel to prevent it from falling off; the elastic plate is made of polyurethane and has a static friction coefficient in the range of 0.1 to 0.4 to ensure the smoothness of the structural surface, and the elastic plate achieves repeated sliding and telescopic functions with the channel through the light transmittance and wear resistance of its material.

[0015] The explanation for the material requirements of the elastic plate is that, according to the structural design, the elastic plate needs to be able to return to its original shape after multiple bending deformations. Therefore, the selected material needs to have excellent elasticity and strength to withstand multiple deformations without losing its original performance. The selected polyurethane material is a common polymer elastic material that can be manufactured through different manufacturing processes. Furthermore, the structure of the elastic plate and the excellent wear resistance and durability of polyurethane material can meet the problem of not aging easily after long-term use. At the same time, compared with traditional rubber materials, polyurethane elastomers are lighter, which can bring lower energy consumption and transportation costs.

[0016] Furthermore, since the elastic plate needs to slide within the channel, it must have a suitable area to move in after gas expansion without falling off, and the friction between the elastic plate and the channel must not affect the sliding process. Therefore, one side of the elastic plate is provided with a rectangular groove, which contacts the air cavity, allowing the gas in the air cavity to enter the rectangular groove after expansion and for the rectangular groove to be pushed. The other side of the elastic plate is a smooth surface, formed by grinding and polishing, spraying polyurethane coating or polyurethane acrylate, hot pressing, and vacuum forming. To prevent the elastic plate from falling off when it reaches a stationary state after contraction, a blocking block is provided at the initial end of the elastic plate. This blocking block can hold the elastic plate within the channel when it naturally recovers its shape.

[0017] Secondly, it should be mentioned that since the application scenario of this invention is agricultural planting, the gradual change in light intensity can simulate the changes of day and night. Since the light changes according to temperature, the elastic plate itself is made of polyurethane material during the design process. Polyurethane material has a certain light transmittance, but the light transmittance changes with factors such as material thickness and color. Therefore, when the elastic plate gradually bends and wraps around the shell, the thickness will gradually increase, causing the light to be gradually blocked and gradually become hazy, thereby achieving the effect of changing light intensity.

[0018] From an energy-saving perspective, the extended end of the elastic plate is provided with a sensor, which is used to cooperate with the edge of the housing. When the elastic plate is retracted into the winding mechanism, that is, when the initial end of the elastic plate is in contact with the baffle, the sensor sends a signal to the control mechanism to control the power supply to be turned off.

[0019] The number of elastic plates is set within the range of 10-16, preferably 12. Dividing them into 12 according to the angle of the cylinder can allow light to be diffusely reflected on the surface of the elastic plates. At the same time, after being rolled up, they can have sufficient thickness to cover the light source generated by the light-emitting body. The rectangular groove surface of the elastic plate is set as a smooth structure and sprayed with optical paint to provide a better refraction effect and a smaller friction force in the illumination state.

[0020] According to the usage requirements of the elastic plate, a locking structure is provided at one end of the top cover. The locking structure includes a twisting disc, a locking block, and a locking channel. The twisting disc is a cylindrical structure and is rotatably mounted at one end of the housing. The locking block is rotatably connected to the outer edge of the twisting disc and is a rectangular block. One end of the locking block is slidably connected to the locking channel. A movable area is provided on one side of the locking channel, which allows the elastic plate to enter the channel in one direction. The locking channel is located inside the housing, and the locking block is slidably connected to the locking channel. The locking structure is used to lock the elastic plate in one direction by twisting.

[0021] The design requires that the number of the locking blocks be the same as the number of the elastic plates. The locking structure is used to engage with the rectangular groove to achieve the sliding function. Since the locking blocks are engaged in the engagement channel by rotation, the locking blocks have a certain bending space, allowing the elastic plates to slide only in one direction.

[0022] The cleaning mechanism is located at the entrance of the winding mechanism. The cleaning mechanism is a clamp-type structure and is in close contact with the elastic plate. The cleaning mechanism is used to clean the dust during each sliding and extending process of the elastic plate, thereby ensuring the sealing of the channel and the diffuse reflection effect of the material.

[0023] The cleaning mechanism includes an upper cotton block and a lower cotton block. The cleaning mechanism can clean the surface of the elastic plate each time the elastic plate extends, ensuring the sealing between the rectangular groove and the channel and the stability of the light refraction effect.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. This invention enables the adjustment of light intensity by LED light sources during agricultural greenhouse cultivation without human intervention, thereby simulating the changes of day and night. By using the heat generated by the LED lights themselves to promote gas expansion, the light intensity gradually decreases, reducing transpiration in plants at high temperatures and slowing down water loss, thus increasing yield. This improves the accuracy of regulation and greatly reduces energy waste.

[0026] 2. This invention designs the external shape and internal structure of the winding mechanism to retract the extended elastic plate, achieving a larger structure in a smaller space. Furthermore, due to the material limitations of the shell and the elastic plate, light can cooperate with the elastic plate and the shell during the operation of the winding mechanism. Through superposition and linkage, the light is changed, thereby achieving the change of day and night light to meet the needs of plant growth.

[0027] 3. This invention achieves efficient dust removal by using a clip-type structure formed by upper and lower cotton blocks that fits tightly against the elastic plate, ensuring sealing and diffuse reflection of the material during each sliding and extending process of the elastic plate. The cleaning mechanism cleans the surface of the elastic plate each time it extends, maintaining the internal sealing of the equipment and stable light refraction, ensuring that the elastic plate remains clean and efficient during use, thereby improving the product's service life and performance. Due to the clip-type structure of the cleaning mechanism, the cleaning effect is more efficient and can effectively remove dust, resulting in a longer product service life and more stable performance.

[0040] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0041] Example 1:

[0042] like Figures 1 to 4 As shown, an energy-saving and environmentally friendly LED lamp is provided, including a housing 1, a light-emitting body 2, a winding mechanism 3, an elastic plate 4, and a cleaning mechanism 5.

[0043] like Figure 5 As shown, the main body of the device is a cylindrical structure. This structure facilitates the light-emitting body 2 to emit light at one end of the elastic plate 4. As the elastic plate 4 gradually contracts, the light gradually dims, creating a soft gradient effect. On the other hand, when the device is fully extended, the overall brightness can be improved through the diffuse reflection effect of the elastic plate 4. The shell 1 has a hollow structure inside, and its main function is to fix the light-emitting body 2 inside the shell 1 so that the light-emitting body 2 can emit light under the obstruction of the shell 1 and blur the light, thereby achieving the effect of alternating day and night.

[0044] The housing 1 is also equipped with the winding mechanism 3, which is slidably connected to the elastic plate 4. The elastic plate 4 is a rectangular thin plate, and its larger side is engaged with the winding mechanism 3 to ensure that there is enough space in the winding mechanism 3 to retract the elastic plate 4. Because the elastic plate 4 is designed as a rectangular thin plate, the channel 32 in the winding mechanism 3 can be easily slidably connected to the elastic plate 4 and maintain airtightness. The winding mechanism 3 receives the heat generated by the light-emitting body 2 and relies on the pressure of gas thermal expansion to realize the sliding of the elastic plate 4 in the winding mechanism 3.

[0045] One end of the winding mechanism 3 is fixedly connected to the cleaning mechanism 5, which is used to clean the elastic plate 4 when the winding mechanism 3 is in operation, so as to ensure the airtightness between the elastic plate 4 and the winding mechanism 3. The light-emitting body 2 is electrically connected to the control mechanism, and the control mechanism can control the light-emitting body 2 through electrical signals.

[0046] like Figure 6 and Figure 7 As shown, the housing 1 includes an upper cover 11, a cylindrical body 12 and a lower cover 13. The cylindrical body 12 is a hollow cylinder, and the inner diameter of the cylindrical body 12 is one-third of the outer diameter, so as to provide sufficient space for the winding mechanism 3 so that the elastic plate 4 can be rolled up in the cylindrical body 12. The cylindrical body 12 is made of polycarbonate.

[0047] Based on the ratio of one-third between the inner diameter and the outer diameter, the winding mechanism 3 has sufficient space to retract the elastic plate 4 during processing due to the length of the elastic plate 4. Since the elastic plate 4 is rolled up inside the housing 1, the elastic plate 4 has a larger design space and can be stably retracted.

[0048] The cylindrical body 12 is made of polycarbonate, a material with many excellent properties. First, polycarbonate is a high-performance, transparent, and high-strength plastic material, which makes it very suitable as the material for the shell 1. Polycarbonate has excellent impact resistance, which means that the elastic plate 4 can slide repeatedly within the channel 32 without damaging the shell 1. Polycarbonate has a high refractive index and light scattering properties, which allows the light emitter 2 to produce highly transparent light in the hollow structure inside the shell 1.

[0049] Since polycarbonate has a light transmittance of over 90%, the light generated by the light-emitting body 2 can easily pass through the housing 1 and be scattered. Due to the good diffuse reflection effect of polycarbonate, when the elastic plate 4 is fully extended, the light generated by the light-emitting body 2 can penetrate the housing 1 and pass through the elastic plate 4 to achieve a good diffuse reflection effect. Using polycarbonate as the material of the housing 1 can greatly improve the brightness and uniformity of the light-emitting body 2, thereby improving the overall performance and quality of the device.

[0050] like Figure 8 As shown, the winding mechanism 3 is composed of multiple components, including an inlet 31, a channel 32, a baffle 33, and an air chamber 34. The channel 32 is spirally arranged inside the housing 1 around its central axis. This spiral arrangement allows the channel 32 ample space to bend within the housing 1, accommodating the sliding of the elastic plate 4 within the channel 32. The number of channels 32 corresponds to the number of elastic plates 4; therefore, the channel 32 is rationally allocated according to the number of elastic plates 4, resulting in a more compact and efficient structure for the winding mechanism 3. The inlet 31 engages within the channel 32, sealing the gas and ensuring the air chamber 34 is properly positioned. 4. Stable gas delivery; simultaneously, the inner wall of the channel 32 is equipped with a sealing element to maintain airtightness; the baffle 33 is fixedly connected to the end of the channel 32, allowing the elastic plate 4 to be locked in place during sliding, thus preventing the elastic plate 4 from sliding out of the channel 32; the baffle 33 and the channel 32 are sealed by a sealing element to prevent gas leakage; the gas cavity 34 is fixedly connected to one side of the channel 32, the gas cavity 34 is a hollow cavity and communicates with the channel 32, the gas cavity 34 is used to hold expanding gas, and these gases can directly exert pressure on the elastic plate 4 under thermal expansion, thus achieving direct action on the elastic plate 4.

[0051] As the light-emitting body 2 continues to be used, the heat gradually increases over time. Since the air cavity 34 is located inside the housing 1, and the light-emitting body 2 is installed inside the housing 1, the heat is indirectly transferred to the gas inside the air cavity 34. Due to the coefficient of thermal expansion, the gas expands. However, since the air cavity 34 is a fixed space, the gas volume increases, and the pressure inside the air cavity 34 also gradually increases. With the locking structure 14 at the inlet 31, the elastic plate 4 can only be pushed in one direction. When the gas exerts a force due to the increased pressure, the force on the inlet 31 is canceled by the locking structure 14, while the force on the baffle 33 continues to push the elastic plate 4. Since the elastic plate 4 has a rectangular groove 421, the inner wall of the rectangular groove 421 near the baffle 33 is subjected to force, and the elastic plate 4 slides in one direction. Therefore, when the gas expands, it pushes the elastic plate 4 to gradually contract.

[0052] The channel 32 is spirally arranged along the central axis of the housing 1. Due to its curved design, it provides ample space for the elastic plate 4 to slide within the channel 32. The number of channels 32 corresponds to the number of elastic plates 4, thus rationally allocating the space of the channels 32. The inlet 31 is connected to the channel 32 and can seal the gas to ensure stable gas delivery to the gas chamber 34. The inner wall of the channel 32 is equipped with a sealing element to maintain the airtightness between the gas chamber 34 and the channel 32. The baffle 33 is fixedly connected to the end of the channel 32 to prevent the elastic plate 4 from sliding out of the channel 32. 34 is a hollow cavity fixedly connected to one side of the channel 32. The air cavity 34 is connected to the channel 32 and contains expanding gas. Under thermal expansion, the gas directly acts on the elastic plate 4, pushing it towards the baffle 33. Since the elastic plate 4 is provided with a rectangular groove 421, the gas expansion pushes the elastic plate 4 in one direction, causing it to gradually contract. As the heat generated by the light source 2 increases over time, the gas in the air chamber expands and the pressure increases, so that the gas directly acts on the elastic plate 4. The locking structure 14 at the inlet 31 can ensure that the force pushes the elastic plate 4 towards the light source 2.

[0053] The elastic plate 4 includes an initial end 41, a telescopic end 42, and an extension end 43. The elastic plate 4 is a rectangular thin plate. A rectangular groove 421 is provided on one side of the telescopic end 42. Multiple rectangular grooves 421 are linearly arrayed along the side of the elastic plate 4. A blocking block 411 is provided on the initial end 41. The blocking block 411 is used to fix the elastic plate 4 in the channel 32 to prevent it from falling off. The elastic plate 4 is made of polyurethane, and its surface is designed to be smooth. The light transmittance and wear resistance of the material enable it to repeatedly slide and extend with the channel 32. A rectangular groove is provided on one side of the elastic plate 4. The groove 421, with a rectangular groove 421 on one side, contacts the air cavity 34, allowing the gas in the air cavity 34 to expand and enter the rectangular groove 421, and the rectangular groove 421 can be pushed. The other side of the elastic plate 4 is a smooth surface, which is processed by grinding and polishing, spraying polyurethane coating or polyurethane acrylate, hot pressing and vacuum forming, etc., so that the static friction is between 0.1 and 0.4. The reason for setting it to 0.1-0.4 is to allow the elastic plate 4 to slide normally. If the friction is too large, it will jam. To prevent this, grinding and polishing ensure a smooth surface.

[0054] To ensure that the elastic plate 4 can maintain its original performance after multiple bending and deformations, the selected material must have excellent strength and elasticity. Therefore, polyurethane was chosen as one of the materials for the elastic plate 4. Polyurethane is a common polymer elastic material that can be manufactured through different manufacturing processes. The structural design of the elastic plate 4 and the excellent wear resistance and durability of polyurethane can meet the problem of long-term use without aging. Compared with traditional rubber materials, polyurethane elastomers are lighter, which can reduce energy consumption and transportation costs.

[0055] When the gas in the air cavity 34 expands due to heat, the rectangular groove 421 of the elastic plate 4 is subjected to force. The connecting area between the air cavity 34 and the channel 32 includes a rectangular groove 421 and a half rectangular groove 421 on each side, so that the force can continuously push. The elastic plate 4 is continuously pushed under the action of the expanding gas until the elastic plate 4 contacts the baffle 33, and both ends of the elastic plate 4 are respectively locked. At this time, the elastic plate 4 is fixed in the channel 32.

[0056] Similarly, when the heat disappears, the gas begins to contract and return to the air chamber 34, and the elastic plate 4 gradually begins to recover. Due to the presence of the blocking block 411, the elastic plate 4 will be fixed at the blocking block 411, thereby preventing the elastic plate 4 from falling off.

[0057] In designing the elastic plate 4, the special nature of the application scenario was taken into consideration. Since this product is used in agriculture, the impact of light on plant growth needs to be carefully considered. Under high temperatures, light intensity should be reduced to avoid excessive photosynthesis and alleviate the plant's water evaporation pressure. This is because the photosynthetic capacity of plants may be inhibited under high temperatures. If excessive light is provided, plants will over-photosynthesize, leading to adverse reactions such as energy accumulation and the production of free radicals, which can damage or even kill the plant. In addition, under high light conditions, the transpiration rate of plants will increase, causing them to lose water more quickly. Therefore, polyurethane material was selected for the elastic plate 4. This material not only has good elasticity and strength but also has a certain degree of light transmittance. However, its light transmittance will change due to factors such as material thickness and color. As the elastic plate 4 is wrapped around the shell 1, its thickness gradually increases, thereby gradually blocking light and gradually dimming the light.

[0058] From an energy-saving perspective, the extended end 43 of the elastic plate 4 is provided with a sensor 431. The sensor 431 is used to cooperate with the edge of the housing 1. When the elastic plate 4 is retracted into the winding mechanism 3, that is, when the initial end 41 of the elastic plate 4 is in contact with the baffle 33, the sensor 431 sends a signal to the control mechanism to control the power supply to be turned off.

[0059] The number of elastic plates 4 is set to 12, because after dividing the cylinder into 12 sections with an included angle of 30°, the light can be diffusely reflected on the surface of the elastic plate 4 well. At the same time, after being rolled up, it can have enough thickness to cover the light source generated by the light source 2. The non-rectangular groove 421 surface of the elastic plate 4 is set to a smooth structure and is sprayed with optical paint to provide a better refraction effect and a smaller friction force in the illumination state.

[0060] The upper cover 11 is provided with a locking structure 14, which includes a torsion disc 141, a locking block 142, and a locking channel 143. The torsion disc 141 is a cylindrical structure and is rotatably mounted on one end of the housing 1. The locking block 142 is rotatably connected to the outer edge of the torsion disc 141 and is a rectangular block. One end of the locking block 142 is slidably connected within the locking channel 143. A movable area 144 is provided on one side of the locking channel 143, which allows the elastic plate 4 to enter the housing 1 in one direction. Inside channel 32; the locking channel 143 is located inside the housing 1, the locking block 142 is slidably connected to the locking channel 143, the locking structure 14 is used to lock the elastic plate 4 in one direction by twisting, and the number of locking blocks 142 is the same as the number of elastic plates 4. The locking structure 14 is used to engage with the rectangular groove 421 to achieve the sliding function; since the locking block 142 is engaged in the locking channel 143 by rotation, the locking block 142 has a certain bending space, allowing the elastic plate 4 to slide only in one direction.

[0061] like Figure 9 and Figure 10 As shown, before using the device, by twisting the twisting disk 141, due to the rotational connection of the twisting disk 141, the locking block 142 is extended into the locking channel 143 under the restriction of the locking channel 143. Due to the existence of the limiting of the movable area 144, the locking block 142 can only be bent in one direction, so the locking block 142 engages with the rectangular groove 421 of the elastic plate 4, so that the locking block 142 is fixed in one direction.

[0062] like Figure 4 As shown, the cleaning mechanism 5 includes an upper cotton block 51 and a lower cotton block 52. The cleaning mechanism 5, through the design of the clamp-type structure formed by the upper cotton block 51 and the lower cotton block 52, is closely attached to the elastic plate 4, which can effectively clean dust and ensure the sealing and diffuse reflection effect of the material during each sliding and extending process of the elastic plate 4. The function of the cleaning mechanism 5 is to clean the surface of the elastic plate 4 each time it extends, so as to maintain the sealing between the rectangular groove 421 and the channel 32 and the stable light refraction effect. This advantage ensures that the elastic plate 4 remains clean and efficient during use, thereby improving the service life and performance of the product.

[0063] During operation, according to the current needs of plant growth, by twisting the twisting disk 141 within the locking structure 14, the locking block 142, rotatably connected to the edge of the twisting disk 141, engages with the locking channel 143. Under the action of the twisting disk 141, the locking block 142 is extended into the locking channel 143, and then the locking block 142 of the locking mechanism engages with the rectangular groove 421 of the elastic plate 4. At this time, the locking block 142 can only bend under the force in the direction of the baffle 33, thus completing the unidirectional restriction function. Subsequently, the light-emitting body 2 is opened by the control mechanism. Since the structure of the shell 1 is polycarbonate, it has high light transmittance, allowing the light from the light-emitting body 2 to be diffused. At this time, the elastic plate 4 is in the extended state, and the light is diffused through the elastic plate 4. Furthermore, the material of the elastic plate 4 is polyurethane, which is also translucent, so the light is strong at this time, meeting the needs of plant photosynthesis.

[0064] As usage time increases, problems within the greenhouse worsen. The gas within the air chamber 34 receives heat from the light-emitting element 2, causing it to expand. Due to the design of the rectangular groove 421 on the surface of the elastic plate 4, the gas enters the rectangular groove 421 and gradually pushes the elastic plate 4. The elastic plate 4 slides within the channel 32. Simultaneously, the cleaning mechanism 5 located at the inlet 31 cleans both sides of the elastic plate 4 when it retracts into the housing 1 due to gas expansion, ensuring the airtightness between the elastic plate 4 and the channel 32 is not affected by impurities. When the elastic plate 4 is fully retracted, the baffle 33 and the locking structure 14 fix the elastic plate 4 inside the housing 1. Since the elastic plate 4 gradually bends and retracts into the housing 1, the thickness of the material inside the housing 1 gradually increases, causing the light intensity to gradually weaken, that is, daytime becomes evening. This reduces the photosynthesis of plants under high temperature, reduces the impact of free radicals caused by energy accumulation, and reduces the transpiration rate, thus controlling water. At the same time, when one end of the elastic plate 4 is in contact with the baffle 33, it means that the sensor 431 sends a signal to the control mechanism, thereby turning off the light-emitting body 2.
