[0038] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0039] Refer to Figure 1 、 2 As shown in FIGS. 1, 2 and 3, an embodiment of the present utility model provides a breeding lamp, which includes a lamp housing base 1, a light-emitting element 3 disposed in the lamp housing base 1, and a lens cover 2. The lens cover 2 is installed on the lamp housing base 1 to form a closed space a for accommodating the light-emitting element 3 in a closed manner;

[0040] Among them, the lens cover 2 includes a light incident refraction part 21 and a light exit refraction part 22. Light exit surfaces 221 with a preset inclination angle are provided on both sides of the light exit refraction part 22 to emit light laterally outwards;

[0041] The light incident refraction part 21 is provided with a light incident surface 211 with a preset inclination angle, and the light incident surface 211 is correspondingly disposed above the light-emitting element 3; the light incident refraction part 21 and the light exit refraction part 22 are respectively provided with corresponding light incident refraction walls 212 and light exit refraction walls 222 to refract the light incident from the light incident surface 211 to the light exit surface 221; through the refraction of the light exit refraction wall 222, a weak light area b for shielding the light source is formed between the two light exit surfaces 221 on both sides, and the light-emitting element 3 is correspondingly located below the weak light area b. That is, under the shielding of the weak light area b of the light-emitting element 3, the area that would originally have overexposure directly opposite the light-emitting element 3 becomes dim, and the light in this area can be supplemented by the reflection of light from other areas according to the actual scenario, thereby obtaining a high-uniformity lighting effect.

[0042] Specifically, in order to more accurately control the light emitted from the light exit surface 221, the light exit surface 221 is a Fresnel tooth surface, so that the light emitted through the Fresnel tooth surface can have high transmittance and light mixing while accurately controlling the direction of light, thereby improving the lighting effect.

[0043] The lens cover 2 further includes face covers 23 disposed on both sides of the light exit refraction part 22. One end of the face cover 23 is connected to the light exit refraction part 22, and the other end is provided with an auxiliary installation edge 231 for installation downward;

[0044] Limiting grooves 11 for inserting the auxiliary installation edges 231 are provided on both sides of the top of the lamp housing base 1 to limit the lateral movement of the lens cover 2.

[0045] Accordingly, a retaining edge 12 for restricting the auxiliary mounting edge 231 from disengaging from the limiting groove 11 is provided on the outer side of the limiting groove 11, thereby stabilizing the installation of the lens cover body 2.

[0046] In order to make the light emitted through the face cover 23 be emitted obliquely outward relatively, the surface of the face cover 23 is an inclined surface that is inclined downward relative to the light-emitting refraction portion 22.

[0047] Moreover, a light-leaking edge 232 extending upward by a preset height is provided at the top of the auxiliary mounting edge 231, so as to form a light-leaking gap c between the retaining edge 12 and the face cover 23 through the light-leaking edge 232. With such a setting, the light laterally emitted by the light-emitting element 3 can be reflected by the light-leaking gap c to make up for the light in the weak light area b.

[0048] In order to facilitate the determination of the installation position of the light-emitting element 3, the light-emitting element 3 includes a light-emitting light source 31 and a lamp board 32 for power supply connection with the light-emitting light source 31; on the lamp housing base 1, a board groove 13 for defining the position of the lamp board 32 is provided in the enclosed space a, so that the light-emitting light source 31 located on the lamp board 32 is located below the weak light area b. Preferably, the light-emitting light source is an LED lamp bead or a light strip.

[0049] On the other hand, in order to facilitate the installation and use of the present application, deformable base bottom edges 14 are provided on both sides of the bottom of the lamp housing base 1, and a multi-functional connection groove 15 is formed between the two base bottom edges 14 on both sides, so that an external plug-in member can be conveniently inserted into the multi-functional connection groove 15 to complete the connection. Preferably, a channel body 16 for threaded connection is provided in the multi-functional connection groove 15.

[0050] More preferably, a clamping edge 141 is provided on one side of the bottom end of the base bottom edge 14, and a clamping groove 142 is provided on the other side. The setting of the clamping edge 141 can utilize the principle of a clamping jaw to clamp the required installation part outside, and the setting of the clamping groove 143 can facilitate the external clamping jaw 4 to be buckled in to complete the connection.

[0051] The light-emitting surface 221 and the light-incident surface 211 are respectively located above and below the face cover 23 relatively, and the bottom surface of the light-incident refraction portion 21 is in an inverted V shape to form two symmetrically arranged light-emitting surfaces 221, so as to output light to the light-incident refraction walls 212 and the light-emitting refraction walls 222 on both sides respectively.

[0052] On the other hand, in order to improve the refractive index of the light-incident refraction wall 212 and the light-emitting refraction wall 222 for light while also strengthening the light-shielding effect of the weak light area b, an extrusion film or a high-emission electroplated film 5 for improving the reflectivity is provided on both the light-incident refraction wall 212 and the light-emitting refraction wall 222.

[0053] Preferably, the lens cover 2 has an integrated structure and is made of a light-transmitting material such as plexiglass or acrylic. That is, part of the light of the light source can be emitted not only from the light-emitting surface 221 but also from the face cover 23. Thus, after the light of the light source is refracted by the lens, light rays are emitted in multiple directions. The light rays obtained by mixing in such multiple directions are more conducive to the growth of light-sensitive organisms such as microalgae.

[0054] Regarding the optical change principle of this application, its working principle is that most of the light rays emitted by the lamp beads are refracted into the lens through the principle of conservation of optical expansion, and then the refraction and reflection of the light rays are realized by the edges with different slopes inside the lens (such as the incident light refraction wall 212 and the outgoing light refraction wall 222).

[0055] Specifically, it satisfies the law of refraction of light: n1sinθ1 = n2sinθ2

[0056] θ1 and θ2 are the incident angle and the refraction angle respectively. n1 is the refractive index of air, and n2 is the refractive index of PMMA, which is 1.49. According to the light source being a Lambert source with an angle of 120°, the length and slope of the incident light surface 211 of the lens can be controlled so that the incident angle of the light rays is between 0 - 79°. When light enters from an optically thinner medium into an optically denser medium, the incident angle > is greater than the refraction angle. From the law of refraction, it can be obtained that the refraction angle entering the lens is in the range of 0 < θ2 < 40.5°.

[0057] The light rays from the light source to the incident light surface 211 and the outgoing light surface 221 of the lens cover 2 all satisfy the law of optical expansion:

[0058] dU = n^2dΣcosθdΩ

[0059] dΣ is the area element; θ is the angle between the normal vector ndΣ of the area element and the central light ray; dΩ is the solid angle element of the light beam; n is the refractive index of the transparent medium, as Figure 4 shown.

[0060] For the same medium, the light incident on the surface ε to the surface s satisfies the law of conservation of optical expansion:

[0061] dU_ε = dU_S

[0062] dU_ε = n^2dεcosθ_εdQ_ε

[0063] dU_s = n^2dscosθ_s dQ_s

[0064] The incident light refraction wall 212 and the outgoing light refraction wall 222 of the lens in the medium satisfy the law of reflection. The light ray direction of the optical system is as Figure 3As shown, the incident light is in air with a refractive index of 1. The light refracts into the PMMA lens material with a refractive index of 1.49. We obtain that the critical angle {θ_c = arcsin(n2 / n1)} is approximately equal to 42°. Therefore, when the light is reflected by the light-emitting refraction wall 222 and the exit angle is greater than the critical angle, total internal reflection will occur at the light-emitting refraction wall 222 and the light cannot exit. According to the law of refraction, to obtain an exit light with an angle of 164° - 175°, its exit angle must be between 4.71° and 12°. Finally, the light is refracted and deflected out through the Fresnel tooth surface of the light-emitting surface 221.

[0065] Therefore, the incident light surface 211 is provided with an incident light slope and an incident light width relative to the light source so that the incident angle of the light from the light source relative to the incident light surface 211 is within 0° - 79°.

[0066] Both the incident light refraction wall 212 and the light-emitting refraction wall 222 are arranged at a preset inclination angle so that, according to the inclination rate and width of the incident light surface 211, the light emitted from the light-emitting surface 221 is emitted at a required optimized angle; the optimized angle is between 164° and 175°.

[0067] See Figure 5 , which is the light effect diagram of the breeding lamp of the present invention. The size of the illuminated surface is 400×1000mm. The distance between the light-emitting surface of the lamp and the illuminated surface is 20mm. In Figure 5 , what is shown from top to bottom are respectively the illuminated surface (in a rectangular shape), the emitted light (in a crescent shape), and the breeding lamp.

[0068] Correspondingly, see Figure 6 which is the optical effect diagram of an existing unoptimized breeding lamp. Compared with the breeding lamp of the present invention, see Figure 7 , it can be clearly known that some of the light in the breeding lamp of the present invention irradiates to both sides of the illuminated surface, not only significantly improving the illumination uniformity, but also greatly reducing the exposure degree at the center.

[0069] Therefore, in the aspect of being applied to microalgae cultivation, compared with the existing breeding lamps in the prior art. The present invention precisely controls the light in multiple directions by designing the lens cover 2, enabling the illuminated surface to achieve the effects of high uniformity and low exposure. After passing through the lens cover 2, the light can evenly irradiate the microalgae surface without causing exposure. Not only achieving the ideal optical effect, but also greatly reducing the stress response of aquatic products during long-term irradiation, enabling the microalgae to grow healthier in a suitable light environment.

[0070] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
