Description

Technical Field

[0001] This utility model relates to an algae removal lamp, specifically an intelligent algae removal lamp based on spectral recognition. Background Technology

[0002] Currently, abnormal algae growth is a common problem in aquaculture, waterscape design, and scientific research water environments. Algae can grow rapidly under suitable light, water temperature, and nutrient conditions, not only affecting water transparency and aesthetics but also competing with aquatic plants for resources, disrupting the ecological balance, and even threatening the health of fish. Therefore, effectively controlling algae growth has become a widely recognized technical challenge in related industries.

[0003] Existing technologies for algae removal mainly fall into two categories: one is to destroy the cell structure of algae through ultraviolet (UV) irradiation; the other is to inhibit or kill algae by adding chemical algaecides. However, the former carries the risk of harming beneficial aquatic organisms such as aquatic plants, corals, and fish due to the UV band, and it is difficult to adjust the irradiation parameters for specific algae; the latter has problems such as water pollution, toxic residues, and complex operation, which are not conducive to long-term ecological maintenance.

[0004] In recent years, some products have attempted to use multi-band LED light sources to replace UV lamps for ecological algae removal. However, most of these products rely on fixed wavelengths or timed control, lacking dynamic identification and precise control mechanisms for algae distribution. They still cannot achieve a comprehensive balance of intelligence, directionality, and safety, and suffer from defects such as low irradiation efficiency, high energy consumption, and poor environmental adaptability.

[0005] Therefore, there is an urgent need to develop an intelligent algae removal device with a reasonable structure, controllable spectrum, strong identification ability, and safety and environmental protection, so as to achieve accurate identification and effective inhibition of specific types of algae, while ensuring spectral safety protection for beneficial organisms such as aquatic plants and fish, and improving the overall algae removal efficiency and the level of intelligence in system operation.

[0015] As a preferred technical solution, the total irradiance output by the LED light source is less than 300 μW / cm², and the emitted light wavelength is limited to the visible light range to avoid harming fish.

[0016] As a preferred technical solution, a heat dissipation plate and a low-noise fan are provided inside the housing to assist in the heat dissipation of the LED light source during operation.

[0017] The beneficial effects of this invention are: by integrating multi-band LED light source components, this invention can combine and output specific wavelength spectra that have an inhibitory effect on different algae (such as blue algae, green algae, diatoms, etc.), making the algae removal process more targeted and selective, effectively improving the algae removal efficiency while avoiding adverse effects on non-target organisms.

[0018] This invention is equipped with a light distribution component and adopts an adjustable focus lens array structure. It can adjust the irradiation angle and focal length of the light beam under different water conditions, so as to achieve concentrated irradiation of algae-dense areas, improve light utilization efficiency, and reduce power consumption.

[0019] This invention is equipped with sensing components, including a hyperspectral imaging unit and an optical detection unit, which can collect spectral reflectance characteristics in water and determine the type and distribution of algae, providing real-time reference for the wavelength combination and illumination strategy of the light source output, and has good environmental adaptability.

[0021] This invention features a band limiting mechanism. The control module includes a limiting circuit that can actively avoid the absorption bands of aquatic plants (such as 680~700nm) and limit the intensity of ultraviolet bands (such as less than 380nm), ensuring the growth safety of aquatic plants and fish and improving the ecological compatibility of the system. Attached Figure Description

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] Figure 1 This is a system block diagram of the present invention. Detailed Implementation

[0024] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0025] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0026] like Figure 1 As shown, this utility model provides an intelligent algae removal lamp based on spectral recognition, and the specific implementation method is as follows.

[0027] The intelligent algae removal lamp in this embodiment mainly includes a housing, a light source assembly, a light distribution assembly, a sensing assembly, and a control module. The housing serves to support and protect the internal structural components, providing the necessary installation space and mechanical strength for the system. It can be made of aluminum alloy or high thermal conductivity plastic material, possessing good waterproof and corrosion-resistant properties, and is equipped with suitable lighting windows and heat dissipation ventilation openings.

[0028] The light source assembly is housed within the housing and includes multiple wavelength-controllable LED light sources. Preferably, the LED light sources include at least blue, green, and red light sources, emitting spectra with center wavelengths of approximately 450nm, 520nm, and 630-660nm, respectively. Specific wavelength combinations can be output based on the photosensitivity characteristics of different types of algae. For example, when cyanobacteria are detected, a bimodal pulse spectrum of 425nm and 630nm can be output; when green algae are detected, a continuous wave spectrum of 520nm and 660nm can be output; and when diatoms are detected, a combination spectrum of alternating flashes of 450nm and 590nm is output. The LED light sources achieve flexible control of wavelength, intensity, and irradiation mode through a driving circuit to achieve targeted suppression of specific algae.

[0029] The light distribution component is located in the direction of the LED light source's emission and includes an adjustable lens array for adjusting the angle and focal length of the illumination beam to achieve precise illumination of areas at different depths and ranges. This lens array features a dynamic focusing structure, with a focal length adjustable between 30mm and 100mm. The focusing mechanism is driven by a motor or electromagnetic drive, offering fast response time and high adjustment precision. It can quickly adjust the illumination coverage area according to the algae distribution, thereby improving light utilization and reducing unnecessary energy consumption.

[0030] The sensing component, also housed within the casing, is primarily used to collect information on the distribution and type of algae in the water. This component includes a hyperspectral imaging module and an optical detection unit. The hyperspectral imaging module acquires the reflectance spectrum data of the water body within the visible light range of 400nm to 700nm, and identifies the optical characteristics of different algae through an embedded spectral feature matching algorithm. It also combines image information to determine the density and distribution area of ​​algae in the water. The optical detection unit assists the imaging system in acquiring supplementary data such as real-time brightness, color, and scattering intensity, providing more accurate environmental information input for subsequent control strategies.

[0031] The control module, as the core control unit of the system, interacts with the light source, light distribution, and sensing components via electrical connections. Internally, the control module includes a main control chip, a power management module, a signal acquisition interface, and a control command output interface. By receiving data from the sensing components, the control module analyzes the current algae type and density, and accordingly controls the operating wavelength and irradiation intensity of the LED light source in real time. Simultaneously, it adjusts the lens focal length of the light distribution component to achieve dynamic algae removal. The control module also includes a time control circuit to start or stop the algae removal lamps according to a preset algae removal time strategy. For example, it can automatically start the algae removal function between 2:00 AM and 4:00 AM to avoid the active period of fish and reduce disturbance to the ecological environment; or it can implement a pulse irradiation strategy, such as irradiating for 10 minutes followed by a 20-minute interval, to improve the algae removal effect while reducing algae resistance.

[0032] The control module also features PID closed-loop control, continuously monitoring algae density information from sensors and comparing it with target values ​​to automatically adjust the LED light source's intensity, achieving dynamic closed-loop adjustment of light output. To further enhance ecological safety, the control module incorporates a band-limiting mechanism. Sensitive wavelengths for aquatic plants (e.g., 680-700nm) can be set as avoidance zones in the control logic, blocking the activation of light sources in those wavelengths in the control output. Simultaneously, the LED's emission spectrum is limited to the visible light range, avoiding the use of ultraviolet wavelengths (e.g., UV-A < 380nm), effectively protecting the photosynthesis of aquatic plants and the visual safety of fish. The total irradiance of the LED light source is also controlled to less than 300μW / cm², ensuring that prolonged irradiation will not cause thermal damage or behavioral abnormalities to organisms.

[0033] To ensure the stability and lifespan of the LED light source under high-power operation, the LED light source assembly is mounted on a high thermal conductivity heat dissipation substrate made of copper-graphene composite material. The substrate and the metal outer shell of the housing are integrally molded, which not only improves structural compactness but also significantly reduces thermal resistance and enhances heat dissipation efficiency. Furthermore, auxiliary heat dissipation devices are installed inside the housing, including a vapor chamber and a low-noise fan. The vapor chamber quickly and evenly distributes the heat generated by the LED operation to all heat dissipation surfaces within the housing, while the fan is driven by magnetic levitation technology, maintaining its speed while keeping noise levels below 18dB, meeting the requirements of low-noise environments such as homes and aquariums.

[0034] The intelligent algae-removing lamp based on spectral recognition provided by this utility model effectively improves algae removal efficiency while reducing the risk of interference to the aquatic ecosystem by targeting and combining the spectral recognition of various algae. It realizes an intelligent, low-energy-consumption, and eco-friendly algae control solution, which is suitable for various scenarios such as home aquariums, commercial landscape ponds, and aquaculture facilities.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
