Description

Technical Field

[0001] The utility model relates to the technical field of edible fungus cultivation, and in particular to a lighting device. Background Art

[0002] Seafood mushrooms are low-temperature grass-growing fungi or wood-growing white-rot fungi. They have high nutritional and medicinal value. They are white in color, thick in flesh, delicate in taste, fragrant and delicious. The amino acids in the protein of seafood mushrooms are complete, including 8 essential amino acids for the human body, and they also contain several polysaccharides. The hot water and organic solvent extracts of their fruiting bodies have the function of removing free radicals from the human body. Therefore, eating seafood mushrooms regularly has the effects of anti-cancer, cancer prevention, improving immunity, preventing aging and prolonging life. It is an edible fungus with high nutritional and medicinal value. It is white in color, thick in flesh, delicate in taste, fragrant and delicious. The optimum temperature for the growth of mycelium is 24-26℃, and the optimum temperature for the growth of fruiting bodies is 8-18℃. Cultivated in autumn and winter, the age of the fungus is about 50 days, the growth cycle is 100 days, and the bioconversion rate is 60-80%.

[0003] In the cultivation process of seafood mushrooms, light conditions are an important factor affecting their growth and yield. Seafood mushrooms do not require light during the mycelium growth stage, but weak light is required during the reproductive stage to promote the normal development of the primordium. The fruiting body has obvious phototropism during growth, and it is ideal to control the light at 200-1000lx during the fruiting stage. Studies have shown that compared with white light, the fruiting body irradiated by blue light has a straight, shorter and thicker stipe, a larger cap, and a higher quality of adult seafood mushrooms.

[0004] In the prior art, LED light strips are usually used to provide a lighting environment for the growth of seafood mushrooms. The LED light strips are placed at the bottom of each layer of the planting rack to illuminate the seafood mushrooms on the lower side. However, the light of the LED light strips is relatively concentrated, and the light is not diffuse and uniform enough, resulting in uneven growth of seafood mushrooms. In addition, the seafood mushrooms grow toward the light, the stems are bent, and the appearance quality is poor, which affects the sales of seafood mushrooms. In addition, LED light strips are mostly white monochromatic light, which cannot meet the demand of seafood mushrooms for blue light. Therefore, a lighting device with uniform light and color adjustment is needed to solve the above problems. Utility Model Content

[0005] In view of the existing deficiencies, the utility model provides a lighting device that solves the problems raised in the above-mentioned background technology. The device can adjust the light generated by the LED light strip into scattered light, and can improve the uniformity of the lighting, reduce the concentration of the lighting, and at the same time can adjust the lighting color according to the growth stage of the seafood mushroom to promote the growth of the seafood mushroom and increase the yield.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A lighting device comprises an outer frame and a back plate, wherein the outer frame is in a stepped structure, a layer of PC uniform light diffusion plate is laid on the lower side of the inner part of the outer frame, a back plate is installed on the upper side of the outer frame by screws, two groups of LED light strips are symmetrically arranged on the front and rear sides of the inner part of the outer frame, and a color change adjustment mechanism is arranged at a position between the two groups of LED light strips inside the outer frame.

[0008] Furthermore, a fixed horizontal plate is transversely fixed inside the outer frame, and a T-shaped limiting slot is opened inside the fixed horizontal plate, and the LED light strip is inserted into the limiting slot.

[0009] Furthermore, both left and right sides of the outer frame are provided with disassembly and assembly slots of rectangular structure, and the disassembly and assembly slots correspond to the positions of the internal limiting slots of the fixed horizontal plate.

[0010] Furthermore, the color change adjustment mechanism includes a color change plate, a drive shaft, a connecting rod assembly and a reduction motor. The drive shaft is transversely penetrated inside the outer frame and is rotatably connected to the outer frame. A reduction motor is installed on the right side of the outer frame, and the output end of the reduction motor is fixedly connected to the drive shaft. Color change plates are arranged on both the front and rear sides of the drive shaft, and the drive shaft is movably connected to the color change plate through the connecting rod assembly.

[0011] Furthermore, the color changing plate is located at the lower side of the LED light strip, and guide grooves are provided on the left and right sides of the inner part of the outer frame at the lower side of the LED light strip, and both ends of the color changing plate are inserted into the guide grooves.

[0012] Furthermore, the connecting rod assembly consists of a secondary connecting rod and a main connecting rod. The main connecting rod is fixedly mounted on the drive shaft. Secondary connecting rods are movably hinged at both ends of the main connecting rod. The secondary connecting rod and the main connecting rod are in a zigzag structure. The outer end of the secondary connecting rod is hinged to the edge of the color change plate.

[0013] Furthermore, the PC light-homogenizing diffuser plate is milky white, and the color-changing plate is blue and made of the same material as the PC light-homogenizing diffuser plate.

[0014] Furthermore, C-shaped lifting ears are fixedly provided near the four corners on the upper surface of the back plate.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. The utility model can adjust the light generated by the LED light strip into scattered light, improve the uniformity of light, reduce light concentration, and adjust the light color according to the growth stage of seafood mushrooms to promote the growth of seafood mushrooms and increase yield.

[0017] 2. The fixed horizontal plate provided in the utility model is used to fix the LED light strip, and the limit slot provided at the same time is convenient for limiting and fixing the LED light strip, ensuring the stability of the installation of the LED light strip, and ensuring that the LED light strip is not easy to move or loose after installation. The disassembly notch provided is convenient for installing and disassembling the LED light strip, and the disassembly notch greatly simplifies the maintenance and replacement process of the LED light strip, and improves the convenience of use and maintenance efficiency of the lighting device.

[0018] 3. The color-changing adjustment mechanism can realize the physical color-changing adjustment of the LED light strip to meet the needs of seafood mushrooms for different light colors during their growth stages. When the user needs to adjust the light color, the drive shaft rotates along a predetermined trajectory by controlling the rotation direction and speed of the reduction motor. The rotation of the drive shaft is converted into the movement of the color-changing plate through the connecting rod assembly, thereby driving the color-changing plate to move toward the bottom of the LED light strip. Due to the existence of the color-changing plate, the light emitted by the LED light strip will change color when passing through the color-changing plate.

Its function is to change the color of the light emitted by the LED light strip to meet the needs of seafood mushrooms for different light colors at different growth stages. Guide grooves are opened on the left and right sides of the outer frame at the lower side of the LED light strip. The two ends of the color-changing plate are inserted into the guide grooves. The main function of the guide grooves is to guide the color-changing plate to move horizontally, so that the color-changing plate can move smoothly under the constraint of the guide grooves, thereby ensuring the smooth movement of the color-changing plate and preventing the device from shaking or offsetting during movement.

[0020] 5. The connecting rod assembly can convert the rotational force of the drive shaft into the linear movement of the color-changing plate, thereby driving the color-changing plate to move. When the drive shaft rotates, it drives the main connecting rod to rotate, and the main connecting rod drives the secondary connecting rod to rotate. At the same time, the end of the secondary connecting rod moves outward. The secondary connecting rod converts the rotational motion of the main connecting rod into the linear movement of the color-changing plate, and adjusts the position change of the color-changing plate during the movement by changing its angle.

[0021] 6. The PC light-homogenizing diffuser is milky white. The main function of the PC light-homogenizing diffuser is to evenly diffuse the light emitted by the LED light strip, eliminate dark areas and bright spots in the light, and ensure that the entire growth area can obtain uniform illumination. The milky white PC light-homogenizing diffuser can effectively scatter light, so that the light emitted by the LED light strip can be evenly distributed in the entire growth area after passing through the diffuser. The color-changing plate is blue and made of the same material as the PC light-homogenizing diffuser. The main function of the blue color-changing plate is to adjust the color of the light to meet the needs of seafood mushrooms for different light colors at different growth stages. By changing the position of the color-changing plate, the proportion of blue light in the light can be adjusted, thereby achieving precise adjustment of the light color. Blue light promotes the growth of seafood mushrooms, improves photosynthesis efficiency, and promotes growth. BRIEF DESCRIPTION OF THE DRAWINGS

The color-changing adjustment mechanism 5 provided can realize the physical color-changing adjustment of the LED light strip 6 to meet the needs of different light colors in the growth stage of seafood mushrooms. When the user needs to adjust the light color, the rotation direction and speed of the reduction motor 54 are controlled to rotate the drive shaft 52 according to a predetermined trajectory. The rotation of the drive shaft 52 is converted into the movement of the color-changing plate 51 through the connecting rod assembly 53, thereby driving the color-changing plate 51 to move toward the bottom of the LED light strip 6.

The LED light strip 6 is inserted into the T-shaped structure limit slot 41 of the fixed horizontal plate 4 to ensure that the light strip is firmly installed. After the LED light strip 6 is powered on, it emits light to provide the required lighting for plants such as seafood mushrooms. The milky white PC uniform light diffusion plate 3 can evenly diffuse the light emitted by the LED light strip 6, eliminate dark areas and bright spots, and ensure that the entire growth area obtains uniform lighting. When the color of the light needs to be adjusted, start the reduction motor 54, and drive the drive shaft 52 to rotate through the reduction motor 54. The rotation of the drive shaft 52 is converted into a linear movement of the color changing plate 51 through the zigzag structure of the connecting rod assembly 53 composed of the main connecting rod 532 and the auxiliary connecting rod 531. The blue color-changing plate 51 moves along the guide slot 22 to the bottom of the LED light strip 6.
