[0002] Currently, most animal husbandry uses fluorescent tubes and bulbs for lighting. Existing farms often employ multi-level breeding to maximize space utilization. However, because commonly used lighting fixtures do not emit light evenly or accurately, using common fluorescent lamps for multi-level breeding can lead to significant differences in illuminance between the top, middle, and bottom levels, which is detrimental to animal husbandry.

[0003] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a lighting lamp for aquaculture farms, which solves the problem that existing aquaculture lighting lamps cannot meet the requirements of uniform illumination at different heights in multi-layer aquaculture.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A lighting fixture for a farm includes a light source board, a lens, and a lampshade, wherein the lens and the lampshade are detachably connected, and the light source board is disposed between the lens and the lampshade; The light source board is provided with a first light source, and the lens includes a first lens portion, which is opposite to the first light source and is used to converge the light emitted by the first light source; The light source plate is provided with a second light source located around the first light source, and the lens also includes a second lens portion disposed around the first lens portion. The second lens portion is opposite to the second light source and is used to converge the light emitted by the second light source.

[0006] In the above structure, the lens further includes a connecting part disposed on the outer edge of the second lens part, a groove is provided on one side of the lamp cover opening, a first retaining ring is provided on the side wall of the groove, a retaining flange is provided on the connecting part corresponding to the groove, a second retaining ring is provided on the side of the retaining flange near the groove, and the second retaining ring engages with the first retaining ring.

[0017] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0018] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0019] Reference Figures 1 to 4 This utility model provides a lighting lamp for aquaculture farms, which includes a light source plate 1, a lens 2, and a lampshade 3. The lens 2 and the lampshade 3 are detachably connected. The light source plate 1 is disposed between the lens 2 and the lampshade 3. A first light source 11 and a second light source 12 are disposed on the light source plate 1. The first light source 11 is disposed in the middle of the light source plate 1, and the second light source 12 is disposed around the first light source 11. The lens 2 includes a first lens portion 21 corresponding to the first light source 11 and a second lens portion 22 corresponding to the second light source 12. The first lens portion 21 is used to converge the light emitted by the first light source 11, and the second lens portion 22 is used to converge the light emitted by the second light source 12.

[0020] By setting the first lens section 21, the divergent light emitted by the first light source 11 can be converged, ensuring that the light emitted by the first light source 11 is emitted perpendicularly, thus guaranteeing the uniformity of light. In the scenario of multi-layered aquaculture, the perpendicularly emitted light can ensure the uniformity of illumination in the top, middle, and bottom layers. By setting the second light source 12 to compensate for the light emitted by the first light source 11, the overall illumination brightness is guaranteed; and by setting the second lens section 22 to converge the light emitted by the second light source 12, the light emitted by the second light source 12 can also be of a perpendicular light pattern, further ensuring the uniformity of light in aquaculture layers of different heights.

[0021] In this embodiment, both the first lens section 21 and the second lens section 22 are convex lenses. The focal length (F1) of the first lens section 21 is optically designed such that light emitted from the first light source 11, after refraction by the first lens section 21, forms a relatively concentrated main light spot with high central brightness. The focal length (F2) of the second lens section 22 is optically designed such that F2 < F1, so that light emitted from the second light source 12, after refraction by the second lens section 22, forms a relatively concentrated auxiliary light spot with a divergence angle slightly larger than the main light spot and uniform brightness. This ensures that after refraction by the lenses, the main light spot in the center and the auxiliary light spots on the periphery overlap and merge on the illumination surface at a predetermined distance, guaranteeing uniformity of illuminance and brightness at different heights.

[0022] In this embodiment, the transmittance of lens 2 is greater than 90%, preferably 95%, to ensure that the light emitted from the light source is fully utilized.

[0023] Reference Figure 2 Furthermore, in this embodiment, the first light source 11 is disposed in the middle of the light source plate 1, and the second light source 12 is circularly disposed around the periphery of the first light source 11. Correspondingly, the second lens portion 22 is configured as an annular shape, and the first lens portion 21 is disposed in the middle of the annular portion 22.

[0024] Reference Figure 3 and Figure 4 Furthermore, the lens 2 also includes a connecting part 23, through which the lens 2 is connected to the lampshade 3. Specifically, the connecting part 23 is arranged around the outer edge of the second lens part 22. A groove 31 is provided on one side of the opening of the lampshade 3. A first retaining ring 311 protrudes from one side wall of the groove 31. The connecting part 23 is provided with a retaining flange 231 corresponding to the groove 31. A second retaining ring 232 is provided on the side of the retaining flange 231 near the groove 31. When the retaining flange 231 extends into the groove 31, the second retaining ring 232 engages with the first retaining ring 311, thereby connecting and fixing the lens 2 and the lampshade 3. By setting the retaining flange 231 to engage with the groove 31, the lens 2 and the lampshade 3 are connected and fixed. The groove 31 and the retaining flange 231 can, to a certain extent, prevent water vapor and other liquids from entering the interior of the lamp from the connection point, effectively improving the waterproof performance of the lamp.

[0025] Reference Figure 2 and Figure 3Furthermore, a heat sink 4 is provided on the side of the light source board 1 facing away from the lens 2, and multiple connecting posts 32 are provided inside the lampshade 3. The heat sink 4 and the connecting posts 32 are detachably fixed. Specifically, the connection and fixation between the heat sink 4 and the connecting posts 32 can be made using common fasteners such as screws. The connecting posts 32 support the heat sink 4, ensuring the stability of the connection between the heat sink 4 and the lampshade 3. By setting up the heat sink 4, the heat dissipation of the light source board 1 is effectively enhanced, thereby extending the service life of the lighting lamp.

[0026] Preferably, the heat sink 4 is a heat sink aluminum plate.

[0027] Reference Figure 3 and Figure 4 Furthermore, the lens 2 also includes a pressing part 24 located between the first lens part 21 and the second lens part 22, which abuts against the light source plate 1. By providing the pressing part 24, the light source plate 1 is pressed against the heat sink 4, ensuring that the light source plate 1 is tightly attached to the heat sink 4 and guaranteeing heat dissipation. In addition, the pressing part 24 can also limit the movement of the light source plate 1, reducing the possibility of misalignment between the light source plate 1 and the lens 2 during use, which could affect the lighting effect.

[0028] In this embodiment, both the first light source 11 and the second light source 12 are composed of LED chips. LED chips are highly efficient and have a long lifespan, which helps reduce production costs. The partitioned layout of the LED chips, compared to densely arranging all high-power chips in the center, results in a more dispersed heat distribution. Combined with the heat sink 4 attached to the back, heat can be conducted and dissipated more quickly, effectively reducing the junction temperature of the LED chips. Operating at a lower temperature not only results in higher luminous efficacy and lower energy consumption, but also significantly slows down light decay, ensuring the long-term stability of luminous flux and color temperature throughout the lighting module's lifespan.

[0029] Furthermore, the connecting portion 23 is provided with a circular limiting flange 233 on the side facing the light source plate 1, and the inner diameter of the limiting flange 233 is adapted to the diameter of the light source plate 1. The limiting flange 233 is used to further limit the light source plate 1, further reducing the possibility of misalignment between the light source plate 1 and the lens 2.

[0030] Furthermore, the first lens portion 21, the pressing portion 24, the second lens portion 22, and the connecting portion 23 are integrally formed.

[0031] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
