[0025] With the development of modern agricultural technologies, in the field of plant lighting, plant supplementary lighting has developed rapidly in recent years. By dynamically adjusting the lighting environment, the growth of plants can be maintained in a relatively efficient state, which can significantly improve the efficiency of agricultural cultivation. Existing supplementary lighting technologies are still limited to the use of pure LED light sources. When in use, a considerable part of the full spectrum emitted is not absorbed by plants, resulting in a huge waste of the light source. The high energy consumption of pure LED light source supplementary lights during use is an important factor considered by growers. Lasers have extremely high radiant energy flux, excellent monochromaticity, and excellent directivity. Through research on the biological effects produced by plants, it has been found that appropriate doses of lasers can improve the photosynthetic efficiency of plants, promote plant growth and development, solve problems such as insufficient plant lighting and lack of certain light bands in plants, thereby achieving the purpose of increasing plant growth. Laser light sources can provide specific color light sources targeted. The emission angle of laser light sources is small, and the area that can be illuminated is small. Due to the small emission angle of laser light sources and the small area that can be illuminated, it is necessary to spread the laser beam to increase the illuminated area. If you want to expand the illumination range, you can utilize the light diffusion phenomenon. The light diffusion phenomenon can be achieved by making some curved surfaces in the transparent medium through which the light passes, so that the medium forms uneven thickness to change the propagation direction of the light and make it diffuse to increase the illuminated area. Therefore, it is necessary to provide a lighting device that can improve the irradiation effect of the lighting device on plants and at the same time increase the irradiation area of the lighting device.

[0026] Refer to Figure 1 、 Figure 2 and Figure 3 To solve the above problems, an embodiment of the present application provides a lighting device 10 for plant growth, including a housing 20, a lamp cover 30, a laser assembly 40, and a driving module 50. An optical outlet 70 and an inner cavity 60 communicating with the optical outlet 70 are provided on one side of the housing 20. The laser assembly 40 and the driving module 50 are arranged in the inner cavity 60. The driving module 50 is electrically connected to the laser assembly 40. The lamp cover 30 is arranged at the optical outlet 70. A scattering structure 31 is provided on the lamp cover 30. The light emitting surface of the laser assembly 40 faces the scattering structure 31.

[0027] Refer to Figure 2 、 Figure 3 and Figure 4, in the lighting device 10 applied to plant growth, the lighting device includes a housing 20, a lamp cover 30, a laser assembly 40 and a driving module 50. The housing 20 functions to protect the internal components of the lighting device. In some embodiments, the housing 20 can be set to a cuboid structure. The lamp cover 30 is disposed on one side of the laser assembly 40 close to the light outlet 70. The driving module 50 is electrically connected to the laser assembly 40, and the driving component can control the operation of the laser assembly 40. The laser assembly 40 can emit laser light applied to plant growth. An inner cavity 60 communicating with the light outlet 70 is formed on one side of the housing 20. The laser assembly 40 and the driving module 50 are arranged in the inner cavity 60, and the lamp cover 30 is arranged at the light outlet 70. The driving module 50 can control the laser assembly 40 to emit laser light applied to plant growth. Further, the laser light emitted by the laser assembly 40 can be emitted from one side of the light outlet 70 of the housing 20 through the lamp cover 30. A scattering structure 31 is provided on the lamp cover 30. At the same time, the light-emitting surface of the laser assembly 40 faces the scattering structure 31, which can make the light emitted by the laser assembly 40 be emitted to the outside of the lighting device through the scattering structure 31. The scattering structure 31 can increase the lighting area of the lighting device. The cooperation among the housing 20, the lamp cover 30, the laser assembly 40 and the driving module 50 can improve the irradiation effect on plants. Furthermore, the lighting device 10 applied to plant growth can improve the irradiation effect on plants and at the same time increase the irradiation area of the lighting device.

[0028] Refer to Figure 4, in some embodiments, the scattering structure 31 is an uneven scattering surface on the surface of the lamp cover 30. Since the emission angle of a traditional laser light source is small, the area that the laser light source can illuminate is small. In the field of plant lighting, a larger illumination area is required. Therefore, it is necessary to diffuse the laser beam to increase the illumination area of the lighting device. The lighting device 10 for plant growth provided in the present application is provided with a scattering structure 31 on the lamp cover 30. The scattering structure 31 utilizes the phenomenon of light diffusion to create some curved surfaces in the transparent medium through which the laser passes, making the medium have uneven thickness to change the propagation direction of light. In some embodiments, the laser assembly 40 includes a base body 41 and a plurality of laser emission units 42. The design and construction of the laser assembly 40 are crucial for ensuring the performance and efficiency of the laser device. The base body 41 serves as a support structure for the laser emission units 42, providing a stable platform for laser emission. The plurality of laser emission units 42 are spaced along the length direction of the base body 41. The plurality of laser emission units 42 can ensure the diversity and flexibility of the laser, and can meet different application requirements. This structure not only improves the efficiency and accuracy of laser emission, but also enables the laser assembly 40 to adapt to various complex working environments. In some embodiments, the laser emission unit 42 includes a laser chip, and these chips are mounted on the base body 41, and the emission and control of the laser are realized through appropriate electrical connections. In addition, in order to optimize the performance of the laser, components such as microstrip lines and conductive sheets can also be included. These components work together to ensure the efficient transmission and precise control of the laser.

[0029] Refer to Figure 2 and Figure 3, in some embodiments, the laser assembly 40 includes a base body 41 and a laser emitting unit 42. The base body 41 serves to carry the laser emitting unit 42. Specifically, the base body 41 includes a bottom wall 411 and fixed side walls 412 bent and connected to two opposite sides of the bottom wall 411. The fixed side walls 412 can limit the position of the laser emitting unit 42 and play a role in positioning the laser emitting unit 42. In some embodiments, the laser emitting unit 42 can be disposed on the bottom wall 411, and the lamp shade 30 is clamped between the fixed side walls 412 and the housing 20. The laser emitting unit 42 is surrounded by the fixed side walls 412, the bottom wall 411, and the housing 20, which can play a role in positioning the laser emitting unit 42 and also prevent the laser emitted by the laser emitting unit 42 from scattering. The fixed side walls 412, the bottom wall 411, and the housing 20 jointly surround the laser emitting unit 42, enabling the laser emitted by the laser emitting unit 42 to directly emit to the light outlet 70 of the housing 20, thereby preventing laser scattering and improving the light utilization rate of the lighting device 10 applied to plant growth. In some embodiments, the fixed side walls 412 bent from two opposite sides of the bottom wall 411 can be arranged in a symmetric structure, which is beneficial to the installation of the lighting device. In some embodiments, the laser emitting unit 42 can specifically provide a light source of a specific color. When illuminating plants, the growth stage of the plants and the wavelength range required for photosynthesis need to be considered. For example, red light (wavelength range: 610 - 720 nm) promotes the flowering and fruiting of plants and can extend the flowering period. Blue light (wavelength range: 400 - 500 nm) helps with plant growth and leaf formation. Violet light (wavelength range: 380 - 450 nm) and green light (wavelength range: 500 - 600 nm). Violet light can promote plant nutrient absorption and root development, while green light can increase the chlorophyll content and photosynthesis efficiency of plants. In addition, different plants have different light requirements at different growth stages. For example, during the growth stage of plants, blue light is more important for the growth and development of seedlings, while red light is more important for the flowering period and fruit development. Therefore, the spectral range of the lighting device can be adjusted according to the growth stage of the plants to meet their specific needs. In some embodiments, when selecting the spectral range of the plant lighting device suitable for the needs of plants, it can be ensured that red light and blue light are included, and other wavelengths of spectra such as violet light and green light can be considered.

[0030] Refer to Figure 2 and Figure 4, in some embodiments, the lamp cover 30 includes a light-transmitting plate 32, which can improve the light transmittance of the lamp, making the light more evenly distributed. The light-transmitting plate 32 can be made of translucent or transparent materials. In some embodiments, the light-transmitting plate 32 can be made of PC board (polycarbonate board), acrylic board, PMMA (polymethyl methacrylate), etc. These materials have good light transmittance, impact resistance, and lightweight characteristics. For example, the light transmittance of the PC board (polycarbonate board) can reach 89%, almost equivalent to that of glass, and at the same time, it has an impact resistance 250 - 300 times that of ordinary glass. In addition, the light-transmitting plate 32 also has certain sound insulation and heat insulation characteristics, making them not only enhance the aesthetics of the lighting device visually but also improve the practicality of the lighting device. The light-transmitting plate 32 can pass through the light outlet 70 of the outer shell 20 from the inner cavity 60. The periphery of the light-transmitting plate 32 can be abutted against the light outlet 70 to increase the tightness between the light-transmitting plate 32 and the outer shell 20 and prevent light leakage from occurring in the lighting device. In some embodiments, the scattering structure 31 is located on the light-transmitting plate 32. Protrusion units can be provided on the scattering structure 31 to scatter the light on the protrusion units, thereby realizing uniform distribution of the light in all directions. The scattering structure 31 can increase the lighting area of the lighting device. In some embodiments, the lamp cover 30 further includes a clamping plate 33 connected around the light-transmitting plate 32. The clamping plate 33 is clamped between the fixed side wall 412 and the outer shell 20 to form a sealed cavity among the clamping plate 33, the fixed side wall 412, the light-transmitting plate 32, and the outer shell 20, which can prevent water leakage in the lighting device 10 applied to plant growth, is beneficial to the maintenance of the lighting device, and at the same time can make the light emit uniformly from the light outlet 70 of the outer shell 20, avoiding light leakage and light scattering in the lighting device, being beneficial to reducing the energy consumption of the lighting device, and reducing the comprehensive cost of the lighting device 10 applied to plant growth in plant supplementary lighting.

[0031] Refer to Figure 2 and Figure 3 , in some embodiments, the width of the lamp cover 30 is greater than the width of the light outlet 70, which can prevent the lamp cover 30 from falling off from the light outlet 70. The lamp cover 30 can be embedded into the light outlet 70 from the inside of the outer shell 20. A stepped surface 4120 is provided on the fixed side wall 412. The long edge of the lamp cover 30 abuts against the stepped surface 4120, which can make the lamp cover 30 and the fixed side wall 412 fit tightly. The long edge of the lamp cover 30 can abut against the wall of the inner cavity 60 at the edge of the light outlet 70, making the lamp cover 30, the outer shell 20, and the fixed side wall 412 of the base body 41 fit together, being beneficial to the maintenance of the lighting device, and at the same time can make the light emit uniformly from the light outlet 70 of the outer shell 20, avoiding light leakage and light scattering in the lighting device, being beneficial to reducing the energy consumption of the lighting device, and further reducing the comprehensive cost of the lighting device 10 applied to plant growth in plant supplementary lighting.

[0032] Continue to refer to Figure 2 and Figure 3 In some embodiments, a receiving groove 80 is formed between the snap - in plate 33 and the light - transmissive plate 32. Specifically, the snap - in plate 33 abuts against the step surface 4120 of the fixed side wall 412. The receiving groove 80 between the snap - in plate 33 and the light - transmissive plate 32 is a sealing structure. The receiving groove 80 is formed around the light - transmissive plate 32. In some embodiments, a waterproof ring 81 is provided in the receiving groove 80. The waterproof ring 81 abuts against the inner wall of the inner cavity 60. The waterproof ring 81 can prevent the light - emitting device 10 for plant growth from getting water in, which is beneficial to avoiding water vapor, water mist, etc. from entering the light - emitting device and affecting the normal use of the light - emitting device 10 for plant growth, and is beneficial to the maintenance of the light - emitting device 10 for plant growth, and improves the service life of the light - emitting device 10 for plant growth. In some embodiments, the waterproof ring 81 of the lamp cover 30 is a silicone waterproof sealing ring, which is used to improve the waterproof performance of the lamp cover 30. The waterproof ring 81 can be made of silicone material. The waterproof ring 81 made of silicone material has good waterproof, corrosion - resistant and high - temperature - resistant properties, can effectively protect the light - emitting device from water intrusion, ensure the normal use of the light - emitting device and extend its service life. The design and manufacture of the silicone waterproof sealing ring take into account various use environments of the lamp, including outdoor and indoor, to meet different waterproof requirements. In addition, these sealing rings can be customized according to specific application scenarios. For example, they can be customized according to the size and shape of the receiving groove 80 to ensure the best sealing effect.

[0033] Refer to Figure 3, in some embodiments, the housing 20 is provided with an installation opening on another side adjacent to the side of the light-emitting port 70. The installation opening can be set as a rectangle and can be adapted to the cross-sectional size of the side of the laser assembly 40. The installation opening communicates with the inner cavity 60. When installing the laser assembly 40, the laser assembly 40 can be placed into the inner cavity 60 from the installation opening. The bottom wall 411 and the fixed side wall 412 of the base body 41 are both abutted against the cavity wall of the inner cavity 60, so that when the lighting device is working, the inner cavity 60 is a closed structure to ensure the normal operation of the lighting device. In some embodiments, the lighting device 10 applied to plant growth further includes an end cap 90. The size of the end cap 90 is adapted to the size of the installation opening. The end cap 90 covers the installation opening so that the inside of the inner cavity 60 is a closed structure. After the laser assembly 40 is placed into the inner cavity 60 through the installation opening, the end cap 90 is covered on the installation opening to complete the installation of the laser assembly 40 in the lighting device. In some embodiments, the laser assembly 40 abuts against the cavity wall of the inner cavity 60, and the outer surface of the housing 20 is provided with heat dissipation fins 21. The heat dissipation fins 21 can be made of aluminum or copper. The heat dissipation fins 21 have good thermal conductivity, light weight and easy processing characteristics. The heat dissipation fins 21 can improve the heat dissipation efficiency by increasing the surface area. The heat dissipation fins 21 are arranged around the laser assembly 40 to increase the surface area to improve heat dissipation, so as to enhance the heat dissipation effect of the lighting device.
