Description

Technical Field

[0001] The present invention relates to the technical field of water ecological restoration.

[0002] In particular, the present invention relates to a submerged plant supplementary lighting lamp and its application in submerged plant cultivation. Background Art

[0003] Eutrophication of water bodies caused by excessive input of nitrogen and phosphorus nutrients caused by human activities is one of the water environment issues that has attracted widespread attention in recent years. Eutrophication of water bodies has led to the deterioration of water quality in many lakes, a sharp decline or even digestion of aquatic vegetation, and the growth of harmful algae. Submerged plants are important primary producers in water bodies and important components of aquatic ecosystems. Their presence in water bodies has a significant impact on the structure and function of aquatic ecosystems. Submerged plants can not only adsorb and settle impurities and debris in water bodies, degrade and absorb harmful pollutants in water bodies, but also inhibit the growth and reproduction of harmful algae and provide habitats for aquatic organisms. Therefore, ensuring the healthy growth of submerged plants in water bodies is an issue that needs to be addressed in water ecological restoration.

[0004] In water ecological restoration projects, lighting conditions play a major role in the growth and recovery of submerged plants. With the increase of water depth, due to the loss of sunlight at the junction of water and air and the attenuation in water, the lighting conditions in the deep water body cannot meet the growth needs of submerged plants, which will limit the growth and reproduction of submerged plants. Most of the light-filling devices or light-filling equipment designed for submerged plants in the prior art are complex in structure, inconvenient to install and maintain, and have high cost of use, and are not convenient for multi-point deployment in natural water bodies; and the light-filling devices or light-filling equipment in the prior art do not take into account the different growth needs of submerged plants at different water depths for light, and cannot perform targeted and differentiated light-filling. On the one hand, it will cause excessive light-filling in shallow water areas or insufficient light-filling in deep water areas, affecting the growth and development of submerged plants; on the other hand, it will also cause a waste of part of the light source. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies of the prior art, an object of the present invention is to provide a submerged plant fill light and its application in submerged plant cultivation.

[0006] To solve the above problems, the present invention adopts the following technical solutions:

[0017] The present invention also provides an application of a submerged plant supplementary lighting lamp in submerged plant cultivation.

[0018] Compared with the prior art, the technical effects of the present invention are embodied in:

By utilizing the characteristics of the conical spiral with a small cross-sectional area at the upper end and a large cross-sectional area at the lower end, after being placed in a water body, it can adapt well to different water depths and perform differentiated segmented fill-in light in a targeted manner, which is more conducive to the growth of submerged plants.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The embodiment of the present invention provides a submerged plant fill light, the structure of which is as follows: Figure 1 , Figure 2 , Figure 3 A submerged plant fill light comprises a waterproof lamp housing 1 and a light source 2 encapsulated in the waterproof lamp housing 1; the waterproof lamp housing 1 is in the shape of a conical spiral; the light source 2 is arranged in the shape of a conical spiral in the waterproof lamp housing 1, and the light source 2 comprises a conductive substrate 3 and an LED light-emitting module arranged on the conductive substrate 3, and both ends of the conductive substrate 3 are connected to a power supply. The power supply can be a direct current power supply or a battery power supply.

[0026] The water level depth in rivers, lakes and other water bodies is often inconsistent due to the undulating terrain. Under the irradiation of natural light, the submerged plants at different water depths receive different light intensities and their growth conditions are also inconsistent. Usually, submerged plants in shallow water can obtain sufficient light and grow well, while submerged plants in deep water will have their growth inhibited or even die due to insufficient light intensity. In view of this situation, the present invention provides a fill light with an overall shape of a conical spiral. When in use, the fill light of the present invention is placed in a water body, and the submerged plants above the water body can be irradiated with relatively sufficient sunlight without the need for excessive fill light. Therefore, the fill light can be provided by using the cone top part of the conical spiral of the fill light of the present invention. Since the cross-sectional area of ​​the cone top is small, the illumination intensity provided by the luminous light source contained therein is weaker; while the cone bottom of the conical spiral of the fill light has the largest cross-sectional area, and the illumination intensity provided by the luminous light source contained therein is the strongest, thereby providing sufficient illumination for the submerged plants below the water body that require a large amount of fill light. At the same time, the fill light of the present invention gradually expands in a spiral shape from the upper part to the lower part of the lamp, which just fits the change of the water level depth, thereby providing differentiated, segmented, stepped fill light for the submerged plants at different water level depths, promoting the photosynthesis of the submerged plants, and further promoting the growth and development of the submerged plants.

[0027] On the other hand, the structure design of the fill light of the present invention in the shape of a cone spiral, i.e., a structure that is small at the top and large at the bottom, is conducive to its stability when placed in a body of water. Even without a base, the fill light body itself can stand stably on a plane. Especially when the water level is deep, the fill light of the present invention needs to be designed to be large enough according to the water level depth, so that the cross-sectional area of ​​the bottom of the cone is larger and it is more stable when placed on a plane.

[0028] The submerged plant fill-in light of the present invention is in the shape of a conical spiral as a whole. By utilizing the characteristics of the conical spiral with a small cross-sectional area at the upper end and a large cross-sectional area at the lower end, after being placed in a water body, it can adapt well to different water depths and perform differentiated segmented fill-in light in a targeted manner, which is more conducive to the growth of submerged plants. In addition, the submerged plant fill-in light of the present invention has a very simple structure, is easy to install and maintain, has a low cost of use, and is suitable for large-scale promotion and use in water body restoration.

[0029] Preferably, the LED light module includes at least two LED chipsets connected in parallel. Designing the light source 2 as multiple LED chipsets connected in parallel can improve the light intensity on the one hand, and on the other hand, when in use, even if one set of LED chips is damaged, the parallel connection mode can ensure the normal use of other LED chips.

[0030] Preferably, the LED chipset includes a plurality of blue chips 4 and red chips 5 connected in series. Submerged plants only selectively absorb red light and blue light during photosynthesis. Therefore, designing the LED chipset to be a blue chip 4 that emits blue light and a red chip 5 that emits red light can ensure that submerged plants can perform photosynthesis normally, promote the growth of submerged plants, and at the same time, avoid wasting light in other bands.

[0031] More preferably, the spectrum wavelength of the blue light chip 4 is 400nm~460nm, and the spectrum wavelength of the red light chip 5 is 600nm~680nm, because submerged plants absorb the light of these two bands most strongly during photosynthesis, that is, supplementing the light of these two bands is most conducive to the growth of submerged plants. The blue light chip 4 and the red light chip 5 are arranged alternately on the conductive substrate 3, so that it can ensure that submerged plants at different water depths can obtain sufficient red and blue light irradiation.

[0032] In order to facilitate placement, the submerged plant supplementary light of the present invention further includes a base 6, and the waterproof lamp housing 1 is fixedly mounted on the base 6. The lower part of the waterproof lamp housing 1 can be fixedly connected to the base 6 by using adhesive, or a groove 8 matching the shape and size of the lower part of the waterproof lamp housing 1 can be provided on the base 6, and the waterproof lamp housing 1 can be clamped on the base 6 by using the groove 8.

[0033] More preferably, the base 6 is a tumbler base. In this way, when the fill light is placed in the water body, no matter the water body is disturbed or aquatic organisms in the water body hit the fill light, the fill light can always stand in the water body, thereby playing a fill light role.

[0034] Preferably, the base 6 is symmetrically provided with hanging ears 7, and the hanging ears 7 are provided to facilitate hanging the fill light out of the water body or installing it in the water body.

[0035] Preferably, the conductive substrate 3 is an aluminum substrate. The aluminum substrate is light and has good conductivity, and is often used as a conductive medium for light sources.

[0036] The present invention also provides an application of a submerged plant fill light in submerged plant cultivation. Specifically, when in use, the fill light is placed in a water body with a certain water depth, and the fill light gradually expands in a spiral shape from the upper part to the lower part of the light, which just fits the change of the water depth, to provide differentiated, segmented, stepped fill light for submerged plants at different water depths, promote the photosynthesis of submerged plants, and further promote the growth and development of submerged plants.

[0037] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
