[0038] See also Figure 1 and Figure 2 The present application embodiment provides a photoelectric separation disinfection lighting device, including:

[0039] Control module 1;

[0040] A lighting and disinfection module 2 is electrically connected to the control module 1;

[0041] The light processing module 3 is arranged on the light output side of the lighting and disinfection module 2, and is used to receive and process the light emitted by the lighting and disinfection module 2;

[0042] The optical fiber module 4 is connected to the light output side of the light processing module 3 and is used to receive and transmit the light processed by the light processing module 3;

[0043] The light output module 5 is connected to the light output end of the optical fiber module 4 and is used for receiving and outputting the light transmitted by the optical fiber module 4 .

[0044] The control module 1 is the core control unit of the device, which is responsible for controlling the working state of the lighting disinfection module 2. The module adjusts the switch, light intensity and working time of the lighting lamp 22 and the ultraviolet lamp 23 through a preset program or an external input signal (such as a user control panel or sensor feedback). The control module 1 may include a microprocessor, a control circuit board, a signal input interface and an output interface. The microprocessor generates a control signal according to the preset program or sensor data to control the working state of the lighting lamp 22 and the ultraviolet lamp 23 respectively. The control signal is transmitted to the lighting disinfection module 2 through the control circuit board. The lighting disinfection module 2 consists of a plurality of lighting lamps 22 and a plurality of ultraviolet lamps 23, and the light sources are arranged inside the lamp housing 21. The lighting lamp 22 provides visible light for underwater lighting; the ultraviolet lamp 23 emits ultraviolet light for underwater disinfection. The plurality of lighting lamps 22 and the plurality of ultraviolet lamps 23 are respectively installed in independent circuits and connected to the control module 1 to ensure their independent control. The lamp housing 21 adopts a waterproof and dustproof design to ensure long-term stable operation in a water environment. After receiving the signal from the control module 1, the lighting lamp 22 and the ultraviolet lamp 23 light up and emit light respectively, and these lights enter the light processing module 3 through the light output port. The light processing module 3 is arranged on the light output side of the lighting disinfection module 2, and is used to receive and process the light from the lighting disinfection module 2. The module has a built-in light distributor 32 and a light modulator 33 to realize the multi-channel distribution and intensity adjustment of the light. The light processing module 3 includes a main housing 31, and a light distributor 32 and a light modulator 33 are arranged inside. The light distributor 32 distributes the light to multiple light channels, and the light modulator 33 is used to adjust the light intensity of each light channel. The light emitted by the lighting disinfection module 2 first enters the light distributor 32, and the light is evenly distributed to multiple light channels by the distributor. Then, after the light intensity is adjusted by the light modulator 33, the light enters the optical fiber module 4. The optical fiber module 4 is connected to the light processing module 3, and is used to transmit light to the target area in the water body away from the electrical source. The optical fiber module 4 adopts high-quality multimode optical fiber 41 to ensure low loss during light transmission. An optical fiber 41 amplifier may be provided inside the optical fiber 41 to compensate for the light intensity loss caused by long-distance transmission. The optical fiber module 4 includes a plurality of optical fibers 41, each of which is connected to the output end of the light processing module 3. The optical fiber 41 adopts a durable double-layer protective structure with the characteristics of waterproof and corrosion-resistant. The light enters the optical fiber 41 from the light processing module 3, and after being amplified by the optical fiber 41 amplifier, it is transmitted along the optical fiber 41 to the light output module 5. The light output module 5 is located at the end of the optical fiber module 4 and is used to effectively output the light to the target area of ​​the water body. The output module can be equipped with a concentrator 51 or a diffuser 52 to achieve concentrated irradiation or wide-area irradiation of light. The light output module 5 includes a plurality of concentrators 51 and diffusers 52, each of which is connected to an optical fiber 41.After the light is transmitted from the optical fiber 41 to the output module, the output form of the light is adjusted by the condenser 51 or the diffuser 52, so that the light is evenly distributed in the water body or concentrated in a specific area, achieving the effect of lighting and disinfection. In particular, the present invention can select part of the optical fiber to illuminate a certain local area, and select another part of the optical fiber to illuminate another local area, so that different light beams illuminate different local areas; at the same time, the condenser and diffuser at the end of the light output module 5 of the present invention can further control the light beam spot according to the needs of local lighting. The use of the condenser can further reduce the light spot, making the irradiation area smaller, more focused, and more accurate, while the use of the diffuser can expand the local lighting range, so that only a small amount of optical fiber can also achieve local lighting of a larger area, so that the lighting method is more flexible and meets more needs.

[0045] The technical solution provided in this application is mainly to realize the separation of electric drive control and light by connecting the optical fiber module 4 with the lighting and disinfection module 2, that is, to realize photoelectric separation. Even if the optical fiber module 4 and the light output module 5 used for underwater lighting are set underwater, there will be no leakage, which greatly improves the safety of underwater environmental lighting. In detail, by adopting photoelectric separation technology, the electrical part of lighting and disinfection is completely isolated from the water body, and the light is transmitted into the water body through the optical fiber 41. This design effectively avoids the risk of leakage caused by the electrical part contacting the water body in traditional underwater lighting and disinfection devices, and greatly improves the safety in the water environment.

[0046] The above is a brief introduction to the various components of the photoelectric separation disinfection lighting device. The following will introduce the various components and their details in detail:

[0047] In some embodiments, see Figure 2 , lighting disinfection module 2 includes:

[0048] Lamp housing 21;

[0049] A plurality of lighting lamps 22, mounted on the housing and electrically connected to the control module 1;

[0050] A plurality of ultraviolet lamps 23 are mounted on the housing and electrically connected to the control module 1;

[0051] The control module 1 includes a first control circuit and a second control circuit, the lighting lamp 22 is electrically connected to the first control circuit, the ultraviolet lamp 23 is electrically connected to the second control circuit, and the first control circuit and the second control circuit are independent circuits.

[0052] Furthermore, the plurality of lighting lamps 22 are arranged in a circular array, the plurality of ultraviolet lamps 23 are arranged in a circular array, and the plurality of ultraviolet lamps 23 are disposed around the plurality of lighting lamps 22 .

[0053] The lighting and disinfection module 2 of the present invention is one of the core components of the photoelectric separation disinfection lighting device, which is responsible for emitting visible light and ultraviolet light for lighting and disinfection in water environments. The design of the module ensures independent control and efficient operation of the light source, and is particularly suitable for use in environments such as swimming pools, fountain pools, and hot spring pools. The lamp housing 21 is used to accommodate and protect multiple lighting lamps 22 and ultraviolet lamps 23. The housing design takes into account waterproof, dustproof and heat dissipation functions to ensure the long-term stable operation of the lamp in a water environment. The lamp housing 21 is made of high-strength waterproof materials, such as stainless steel or special alloys, which are corrosion-resistant and highly durable. The surface of the housing is coated with an anti-oxidation coating to further enhance the protective performance. The housing is designed as a sealed structure, equipped with a waterproof sealing ring and a heat sink to ensure that the internal light source is not affected by the external water body, while ensuring that heat is effectively dissipated to avoid overheating of the light source.

[0054] The lighting lamp 22 is installed in the lamp housing 21 and is used to emit visible light to meet the lighting needs in the water environment. Multiple lighting lamps 22 are arranged in a circular array to ensure uniform distribution of light and good lighting effects. High-brightness LED lamp beads are used, which have the characteristics of low energy consumption, high brightness and long life. The LED lamp beads have high luminous efficiency and can provide sufficient lighting in the water environment. Multiple lighting lamps 22 are arranged in a circular array around the center of the ultraviolet lamp 23. This arrangement ensures that the light emitted by the lighting lamps 22 is more uniform.

[0055] The ultraviolet lamp 23 is also installed in the lamp housing 21, and is used to emit ultraviolet light to achieve the function of disinfecting the water body. Multiple ultraviolet lamps 23 are also arranged in a circular array and arranged around the lighting lamp 22. Ultraviolet LED lamp beads in the UVC band are used. The ultraviolet light in this band has a strong bactericidal and disinfecting effect, and can effectively eliminate bacteria and viruses in the water body. The ultraviolet lamp 23 is arranged around the lighting lamp 22 to ensure that the ultraviolet light can fully cover the water body and enhance the disinfection effect. The distance between the ultraviolet lamp 23 and the lighting lamp 22 is accurately calculated to ensure that the light does not interfere with each other and achieve the best light efficiency utilization rate.

[0056] Furthermore, the distance calculation process between the ultraviolet lamp 23 and the lighting lamp 22 is as follows:

[0057] Multiple lighting lamps (denoted as N VIS ) are arranged in a circular array, and these lights are located at a radius r VIS on the circumference.

[0058] Multiple UV lamps (denoted as N UV ) are arranged around the lighting lamp, and the UV lamps are also arranged in circles with the same center as the lighting lamp and different radii r uv on the circumference.

[0059] The lighting lamp and the ultraviolet lamp are arranged around the same center to form a concentric circle array.

[0060] In a concentric circular array, the illumination lamps and UV lamps are evenly distributed on their respective circumferences, and the angle between the lamps can be calculated by the following formula:

[0061] α VIS =360° / N VIS ;

[0062] α UV =360° / N UV ;

[0063] Among them, α VIS Indicates the arrangement angle of the lighting, α UV Indicates the arrangement angle of the UV lamp.

[0064] In the concentric arrangement structure, the light diffusion range of the UV lamp and the lighting lamp is determined by their respective radiation angles:

[0065] R VIS =r VIS ×tan(θ VIS / 2);

[0066] Among them, r VIS is the radius of the lighting lamp from the center of the circle, θ VIS is the radiation angle of the lighting lamp; R VIS It is the light diffusion radius of the lighting lamp.

[0067] R UV =r UV ×tan(θ UV / 2);

[0068] Among them, r UV is the radius of the UV lamp from the center of the circle, θ VIS is the radiation angle of the UV lamp; R VIS is the light diffusion radius of the UV lamp.

[0069] In order to ensure that the light of the UV lamp and the lighting lamp does not interfere with each other, the minimum distance d between the UV lamp and the lighting lamp is min It can be calculated by the respective light diffusion radius. When the UV lamp and the lighting lamp are arranged at the same center, it is necessary to ensure that the intersection area of ​​the two lights is minimized. Therefore, the minimum spacing between the lighting lamp and the UV lamp can be expressed as:

[0070] d min =R VIS +R UV ;

[0071] By using the above formula, it can be ensured that at the edge of the light, the light rays of the two light sources only touch at the intersection point, and no large area of ​​light crossing will occur.

[0072] The lighting lamp 22 and the ultraviolet lamp 23 in the lighting and disinfection module 2 are respectively connected to independent control circuits to ensure their independent control and safe operation. The first control circuit in the control module 1 controls the lighting lamp 22, and the second control circuit controls the ultraviolet lamp 23. The two are independent of each other and do not interfere with each other. The first control circuit: used to control the switching state and light intensity of the lighting lamp 22. By adjusting the current, the brightness of the lighting lamp 22 is controlled to meet the lighting needs of different environments. The second control circuit: used to control the switching state and output intensity of the ultraviolet lamp 23. The second control circuit has overcurrent protection and short-circuit protection functions to ensure the safety of the ultraviolet lamp 23 at work. Independent power supply and protection: The two independent control circuits are respectively connected to independent power supplies and protection devices to avoid overall system failure due to circuit failure and improve the safety and reliability of the system.

[0073] The lighting disinfection module 2 adopts an independent control circuit design to separate the control of the lighting lamp 22 and the ultraviolet lamp 23. This design effectively reduces the risk of system failure. If one of the circuits fails, the other circuit can still operate normally to ensure the continuous operation of the system. In addition, the independent circuit design also enables each light source to operate in the optimal state, avoiding the decrease in light efficiency caused by uneven power distribution.

[0074] The present invention integrates multiple lighting lamps 22 and ultraviolet lamps 23 in the same lamp housing 21, thereby realizing an organic combination of lighting and disinfection functions. The lighting lamps 22 provide high-brightness visible light for underwater lighting, while the ultraviolet lamps 23 emit ultraviolet light in the UVC band for sterilization and disinfection. Through independent control circuits, users can choose to turn on the lighting and disinfection functions simultaneously or use them separately according to their needs, adapting to different application scenarios.

[0075] The circular array arrangement of the lighting lamps 22 and the ultraviolet lamps 23 ensures uniform distribution of light in the water body. The lighting lamps 22 surround the ultraviolet lamps 23, ensuring that visible light can cover every corner of the water body, while the reasonable arrangement of the ultraviolet lamps 23 enables the ultraviolet light to effectively act on the entire water area, ensuring the comprehensiveness of the disinfection effect. In addition, the distance between the light sources is accurately calculated to avoid mutual interference of light and improve the utilization rate of light efficiency.

[0076] Due to the use of high-quality LED lamp beads and the waterproof and dustproof lamp housing 21 design, the lighting disinfection module 2 of the present invention has a long service life. Independent control circuits and reliable electrical protection measures reduce the probability of failure and reduce maintenance costs. In addition, the modular design makes component replacement and maintenance more convenient. Users can replace the lighting lamp 22 or the ultraviolet lamp 23 as needed without replacing the entire module, further extending the service life of the system.

[0077] In some embodiments, the light processing module 3 includes:

[0078] The main housing 31 is sleeved on the light-emitting side of the lighting and disinfection module 2 so that all the light emitted by the lighting and disinfection module 2 enters the main housing 31;

[0079] The light distributor 32 is disposed in the main housing 31 and has a plurality of light channels, and is used to distribute the light emitted by the lighting and disinfection module 2 to the plurality of light channels, and the plurality of light channels are all connected to the optical fiber module 4 .

[0080] The light processing module 3 of the present invention is one of the key components of the photoelectric separation disinfection lighting device, which is responsible for distributing and modulating the light from the lighting disinfection module 2, and then transmitting it to the optical fiber module 4 for long-distance irradiation. The design of this module ensures efficient distribution and precise adjustment of light, and is suitable for multi-point light source control in complex environments.

[0081] The main shell 31 is the external structure of the light processing module 3, which is used to protect the internal optical components and ensure that the light is effectively transmitted internally. The main shell 31 is designed as a closed structure, and its inner wall is provided with a reflective coating to prevent external dust and moisture from entering, while providing effective reflection and guidance of internal light to reduce the loss of light. The main shell 31 is made of high-strength lightweight alloy or high-temperature resistant plastic, and the inner wall is coated with a high-reflectivity coating (such as a silver coating or an aluminum coating) to reduce the loss of light inside the shell. The shell structure is cylindrical or rectangular or in the shape of two cones connected, and the specific shape is determined according to the layout and design requirements of the optical elements. The main shell 31 is installed on the light-emitting side of the lighting and disinfection module 2 through a fixed bracket to ensure that all light can enter the main shell 31 without obstacles. A support structure is provided in the shell to fix the position of the light distributor 32 and the light modulator 33 to ensure the stability of the light path.

[0082] The light distributor 32 is one of the core components of the light processing module 3, which is used to distribute the light emitted from the lighting disinfection module 2 to multiple light channels. The light distributor is arranged on the light output side of the lighting lamp 22 and the ultraviolet lamp 23, and is used to receive the light emitted by the lighting lamp 22 and the ultraviolet lamp 23, and split the light. This component ensures that the light can be evenly distributed to multiple output channels to meet the different input requirements of the optical fiber 41. A plurality of optical lenses and prisms are arranged in the light distributor 32, and the light is distributed to each light channel according to a preset ratio through precise arrangement and design. For example, by adjusting the focal length or light output angle of the lens, the amount of light incident on the light channel at the position can be controlled; the surfaces of the optical elements are coated with anti-reflection coatings to minimize light loss and improve distribution efficiency.

[0083] The light distributor 32 contains multiple optical channels, each of which is connected to a corresponding optical fiber 41 in the optical fiber module 4. These channels can be allocated in a fixed ratio or dynamically adjusted by an adjustment mechanism. The specific design is determined according to the intensity requirements of the light and the application scenario.

[0084] The light modulator 33 is arranged in the subsequent light path of the light distributor 32, between the light channel and the optical fiber module 4, and is used to further adjust the intensity of the light in each light channel. This component can adjust the light intensity of the output light according to the demand to ensure the best lighting and disinfection effect in a complex environment.

[0085] The light modulator 33 uses an adjustable lens or a liquid crystal light valve, which can achieve precise adjustment of the light intensity through mechanical or electronic control. The lens is adjusted by a micro motor or a manual knob, while the liquid crystal light valve is controlled by an electrical signal. The light modulator 33 supports multi-channel synchronous adjustment, that is, the user can adjust the light intensity of all light channels at the same time, or adjust the light intensity of each light channel independently, flexibly adapting to different application requirements.

[0086] The light output side of the light processing module 3 is connected to the optical fiber module 4, and the light output from each optical channel is coupled to the corresponding optical fiber 41 through the optical fiber 41 interface to ensure efficient transmission of light. The optical fiber 41 interface adopts a high-precision alignment design to ensure that the light can seamlessly enter the optical fiber 41 after being output from the light modulator 33. The interface adopts a dustproof and waterproof design to improve the reliability and durability of the connection. The optical fiber 41 is connected to the light processing module 3 through a standardized quick connector, which is convenient and quick to install and maintain, while ensuring the stability of the connection and the efficiency of light transmission.

[0087] The light processing module 3 ensures that the light from the lighting disinfection module 2 can be fully utilized through the efficient light distributor 32 and modulator design. The anti-reflection coating provided inside the light distributor 32 greatly reduces the loss of light during the distribution process, allowing more light to enter the optical fiber module 4 for transmission. This efficient light processing method greatly improves the overall light efficiency of the system and ensures the high-quality output of the remote optical fiber 41 transmission. The light modulator 33 of the present invention is flexible in design and can independently or synchronously adjust the light intensity of each optical channel. This design enables the system to accurately control the output intensity of light according to the lighting requirements of different areas. For example, in areas where stronger lighting or stronger disinfection effects are required, the light intensity of the channel can be increased by the modulator, while normal output is maintained in other areas. This precise control capability ensures the adaptability of the system in various complex scenarios. The multi-channel design and flexible adjustment capability of the light processing module 3 enable the system to adapt to a variety of application scenarios. Whether it is large-area wide-area lighting or small-area concentrated irradiation, the present invention can achieve the desired irradiation effect by adjusting the light intensity of each channel. At the same time, the flexible connection mode of the optical fiber 41 allows the system to be easily expanded or adjusted to meet the application requirements in different environments. The closed structure and high-reflective coating design of the main housing 31 not only protect the internal optical components, but also ensure the effective transmission of light inside. Combined with the high-precision optical fiber 41 interface design, the reliability of the system is greatly improved. In addition, the modular design makes the installation and maintenance of the light processing module 3 more convenient. Users can replace or upgrade components according to actual needs, reducing the maintenance cost of the system.

[0088] In one embodiment, Figure 3 As shown, a lighting area adjustment method is proposed, comprising the following steps:

[0089] Step S1, selecting a lighting mode, wherein the lighting modes include three types: the first mode is a lighting-only mode, the second mode is an ultraviolet disinfection mode, and the third mode is a mixed lighting mode;

[0090] Step S2, operating switches of the first control circuit and the second control circuit according to the selected lighting mode;

[0091] Specifically, it includes: if the first mode, that is, the lighting-only mode, is selected in step S1, the switch of the first control circuit is controlled to be turned on; and the switch of the second control circuit is turned off;

[0092] If the second mode, i.e., the ultraviolet disinfection mode, is selected in step S1, the switch of the second control circuit is controlled to be turned on; the switch of the first control circuit is turned off;

[0093] If the third mode is selected in step S1, the switch of the first control circuit is controlled to be turned on; the switch of the second control circuit is also controlled to be turned on at the same time;

[0094] Step S3, determining the range of the lighting area, wherein the lighting area range includes three modes: local focused lighting, diffused lighting, and dispersed mixed lighting;

[0095] Step S4, determining a lighting area adjustment method based on the lighting mode selected in step S1 and the lighting area range determined in step S3;

[0096] Specifically, for local focused illumination, the light modulator opens the light valve of the light channel corresponding to the condenser at the end, and closes the light valve of the light channel corresponding to the diffuser at the end; for example, if the illumination mode selected in step S1 is ultraviolet illumination, the light valve of the ultraviolet light channel is switched on and off;

[0097] For diffuse lighting, the light modulator opens the light valve of the light channel corresponding to the diffuser at the end, and closes the light valve of the light channel corresponding to the condenser at the end;

[0098] For dispersed mixed lighting, the light modulator opens the light valve of the light channel corresponding to the diffuser at the end, and also opens the light valve of the light channel corresponding to the condenser at the end, that is, all channels are opened, thereby achieving dispersed mixed lighting.

[0099] Furthermore, the light processing module 3 also includes a light modulator 33, which is arranged in the main housing 31 and between the optical channel and the optical fiber module 4. The light modulator 33 is used to adjust the intensity of the light output from each optical channel to the optical fiber module 4. The light modulator 33 is one of the key components arranged after the light distributor 32, and its function is to accurately adjust the intensity of the light entering each optical channel to meet the needs of different application scenarios. The light modulator 33 includes a plurality of adjustable lenses or liquid crystal light valves, and each optical channel corresponds to a modulation unit. The lens is driven by a micro motor, and the liquid crystal light valve is controlled by an electrical signal to change the propagation path or the amount of light passing through. The light modulator 33 is located between the light distributor 32 and the optical fiber module 4. The modulator is installed in the main housing 31 by a fixed bracket to ensure that its position is stable and the optical path is accurately aligned with the interface of the optical fiber 41. The light modulator 33 adjusts the position of the lens or the state of the liquid crystal light valve according to the control signal, thereby changing the intensity and focal length of the light. The modulated light enters the optical fiber 41 through the optical channel to achieve long-distance transmission.

[0100] Furthermore, the light distributor 32 and the light modulator 33 each include a plurality of lenses, and the surface of each lens is provided with an anti-reflection coating. In order to minimize the loss of light in the light distributor 32 and the light modulator 33, the surfaces of all optical elements (such as lenses, prisms and light valves) are coated with an anti-reflection coating. The anti-reflection coating is composed of a multilayer nano-thin film material, such as aluminum oxide, magnesium fluoride, etc., which can significantly reduce the reflectivity of light on the surface of the optical element. The coating is precisely attached to the surface of the optical element through a vacuum coating process to ensure the uniformity and durability of the coating. The application of the anti-reflection coating greatly reduces the reflection loss of light when it passes through each optical element, thereby improving the transmittance of light and the overall light effect. Through this treatment, the transmission efficiency of light in the light processing module 3 is significantly improved.

[0101] In some embodiments, the light processing module 3 also includes a plurality of collimators 34 disposed on one side of the main housing 31 away from the lighting disinfection module. Each collimator 34 is aligned with an optical channel and is located between the light modulator 33 and the optical fiber module 4, and the collimator 34 is connected to the optical fiber module 4. The collimator 34 generally includes one or more convex lenses or cylindrical lenses, which are arranged at the end of the optical channel. Each optical channel corresponds to an independent collimator 34 to ensure that the light can accurately enter the collimator 34 after coming out of the modulator. The lens material is selected from optical glass with high transmittance and low dispersion (such as quartz or high-purity silicon) to reduce the dispersion effect and light loss of the light in the lens. The surface of the lens is also coated with an anti-reflection coating to further improve the light transmittance. The collimator 34 is tightly mounted at the exit of the light modulator 33 and is connected to the main housing 31 of the light processing module 3 through a fixed bracket to ensure its precise alignment with the optical fiber module 4. The main function of the collimator 34 is to convert the divergent light beam output by the light modulator 33 into a parallel light beam. These parallel light beams can be more efficiently coupled into the optical fiber 41, reducing the attenuation and loss of light during the transmission process of the optical fiber 41. When the light passes through the collimator 34, the lens group adjusts the light path according to the incident angle and wavelength of the light, and calibrates the divergent light beam into a parallel light beam. The formation of parallel light beams not only improves the directionality of the light, but also reduces the scattering loss of the light beam in the optical fiber 41. When the parallel light beam calibrated by the collimator 34 enters the optical fiber 41, due to its consistent direction and concentrated energy, it can maximize the use of the transmission channel of the optical fiber 41, improve the transmission efficiency of the optical fiber 41, and reduce coupling loss.

[0102] Further, the optical fiber module 4 includes a plurality of optical fibers 41, each optical fiber 41 is connected to a collimator 34, and an optical fiber 41 amplifier is provided in the optical fiber 41. Each optical fiber 41 is connected to a collimator 34 in the light processing module 3, and corresponds to a condenser 51 or a diffuser 52 of the terminal output module. The optical fiber 41 is made of a material with high light transmittance and low attenuation to ensure efficient transmission of light during transmission. Inside each optical fiber 41, in the middle of the optical fiber 41 path or at a position where the signal needs to be amplified, an optical fiber 41 amplifier is integrated. These amplifiers are mainly used to compensate for the energy attenuation of light in long-distance transmission, and ensure that the intensity of the optical signal remains within a set range. The main function of the optical fiber 41 amplifier is to enhance the intensity of light transmitted in the optical fiber 41, especially under the transmission requirements of long distances or complex environments, the optical fiber 41 amplifier reduces the decrease in light intensity caused by the loss in the transmission path by amplifying the optical signal. In the optical fiber module 4 of the present invention, an erbium-doped optical fiber 41 amplifier is preferably used. The erbium-doped fiber 41 amplifier amplifies the signal light passing through by doping erbium ions into the optical fiber 41 and exciting the erbium ions with an external pump light source. This amplification process does not change the wavelength and phase of the signal light, ensuring the quality of the optical signal. The fiber 41 amplifier is usually installed in the middle of the optical fiber 41 path far away from the light source to compensate for the attenuation during transmission. Depending on the specific application scenario, the number and position of the amplifier can be flexibly adjusted to optimize the amplification effect.

[0103] In some embodiments, the light output module 5 includes multiple concentrators 51 and multiple diffusers 52, and one end of the optical fiber 41 away from the collimator 34 is connected to one of the concentrators 51 or the diffuser 52, and the number of the optical fibers 41 is the sum of the number of the concentrators 51 and the number of the diffusers 52.

[0104] The concentrator 51 is used to concentrate the light transmitted by the optical fiber 41 to form a high-intensity illumination beam, which is suitable for scenes that require concentrated illumination, such as disinfection of a specific area or high-precision lighting. The concentrator 51 is designed with a convex lens or an aspherical lens, which can further focus the parallel light beam into a smaller area, thereby enhancing the light intensity of the local area. The material of the concentrator 51 is selected from high-refractive index optical glass, and an anti-reflection coating is applied on the surface of the lens to reduce light loss and improve light efficiency. The terminal of each optical fiber 41 can be connected to the concentrator 51 through the optical fiber 41 quick connector. The connector is designed to be dust-proof and waterproof to ensure that the light transmission between the optical fiber 41 and the concentrator 51 is not affected by the environment. The output end of the concentrator 51 controls the focusing degree of the light by adjusting the focal length of the lens to adapt to different light intensity requirements.

[0105] The diffuser 52 is used to evenly disperse the light transmitted by the optical fiber 41 and output it, and is suitable for scenes that require wide-area coverage, such as comprehensive lighting at the bottom of a swimming pool or disinfection of a large area. The diffuser 52 is designed with a diffuse lens or prism array, which can refract or reflect the light multiple times, breaking up the light beam to form a uniform light field. The material of the diffuser 52 is low-dispersion optical glass to ensure that the light will not produce obvious dispersion effects during the dispersion process. One end of the optical fiber 41 can be connected to the diffuser 52 through a quick connector to ensure that the light output by the optical fiber 41 can evenly enter the diffuser 52. By adjusting the arrangement of the diffuser 52 or changing the angle of the lens, the distribution range and uniformity of the light can be controlled.

[0106] The light output module 5 can not only realize the focusing and scattering of light, but also realize the combination of different output modes by adjusting the number and arrangement of the condenser 51 and the diffuser 52. The user can choose to use the condenser 51 or the diffuser 52 during installation according to the application requirements, or realize the lighting and disinfection of a specific area by installing a combination of multiple condensers 51 and diffusers 52. For example, some optical fibers 41 are connected to the condenser 51 to realize high-intensity local disinfection, and other optical fibers 41 are connected to the diffuser 52 to provide uniform ambient lighting.
