[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application 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 application and are not used to limit the present application.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0030] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. In addition, the "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if there is transmission of electrical signals or data between the connected objects.

[0031] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0032] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0033] Light scattering refers to the phenomenon that a part of the light deviates from the original propagation direction when passing through an inhomogeneous medium. Obviously, if the light is incident on a homogeneous medium, the light will only be refracted and no scattering will occur. There are many types of light scattering, such as Mie scattering, Rayleigh scattering, Raman scattering, Brillouin scattering, etc. If classified from the perspective of whether the frequency of light can be changed, scattering can be divided into two types: elastic scattering and inelastic scattering. The so-called elastic scattering means that the wavelength (frequency) of light will not change. The incident wavelength of light will remain the same after scattering, such as Mie scattering, Rayleigh scattering, etc. Inelastic scattering means that the wavelength of light changes before and after scattering, such as Raman scattering, Brillouin scattering, Compton scattering, etc.

[0034] Refractive optics, such as converging lenses, produce phase differences based on the optical path difference. Despite their bulky form factor, refractive optics are widely used as optical combiners and imaging optics in near-eye display devices. Diffractive optics, on the other hand, can provide the same phase pattern in a thinner form factor, but their dispersion is usually more pronounced than refractive optics. Another distinct difference between refractive and diffractive optics is their opposite chromatic aberration behavior.

[0035] See also Figure 1 As shown, Figure 1 is a structural schematic diagram of a light-gathering and energy-gathering light-emitting device 1. The embodiment of the present application provides a light-gathering and energy-gathering light-emitting device 1, comprising a light source component 10 and a refraction component 20;

[0036] The light source assembly 10 includes a plurality of light sources 101 and a mounting carrier 102, and the plurality of light sources 101 are mounted on the mounting carrier 102 to generate light;

[0037] The refraction assembly 20 includes a plurality of refraction units 201 , and the plurality of refraction units 201 are matched with a plurality of light sources 101 respectively, and are used to refract the light in multiple gradients.

[0038] Specifically, the light source 101 can be a lamp bead or a light bulb, and its size is not limited. The installation carrier 102 can be an ordinary light panel or a solar light panel, and its shape and size are not limited. In other embodiments, the type of the installation carrier 102 and the light source 101 can be determined according to actual conditions, and they will not be elaborated here.

[0039] Specifically, the multiple refraction units 201 are matched with the multiple light sources 101 respectively, and are used to refract the light in multiple gradients, which means that the refraction units have different refractive indices for the light, so that the light can be refracted in multiple gradients.

[0040] Among them, multiple gradient refraction means that the refraction unit can refract the light and converge it to at least two different positions. For example, if the light source of the device is directed downward, due to the different refractive indices, the brightness of the light at different heights can remain consistent, that is, multiple gradient refraction is achieved for the light.

[0041] The above-mentioned light emitting device 1 includes a light source assembly 10 and a refraction assembly 20; the light source assembly 10 includes a plurality of light sources 101 and a mounting carrier 102, and the plurality of light sources 101 are mounted on the mounting carrier 102 to generate light; the refraction assembly 20 includes a plurality of refraction units 201, and the plurality of refraction units 201 are matched with the plurality of light sources 101 respectively to refract the light in multiple gradients. The above-mentioned light emitting device 1 can converge the light emitted by the light source in a gradient manner, collect light and gather energy, and optimize the illumination effect of the light emitting device.

[0042] See also Figure 2 As shown, Figure 2 A schematic structural diagram of a refraction unit 201. In one embodiment, the refraction unit 201 includes a lens; a plurality of the refraction units 201 include lenses with at least two refractive indices.

[0043] Specifically, a lens is a device used to change or adjust the path of a light beam, and is widely used in the fields of optical communications, imaging, laser processing, etc. Lenses can achieve functions such as deflection, splitting, combining, and focusing of light beams based on different design principles to meet the needs of different optical systems. Therefore, only when there are at least two refractive indices will the brightness of light at different heights remain consistent, that is, multiple gradients of refraction are achieved for light.

[0044] Specifically, lenses are made according to the law of refraction of light. Lenses are optical elements made of transparent materials (such as glass, crystal, etc.). Lenses are refracting mirrors whose refractive surfaces are two spherical surfaces (part of a spherical surface), or a spherical surface (part of a spherical surface) and a flat transparent body. The images it forms are both real and virtual. Lenses can generally be divided into two categories: convex lenses and concave lenses. A convex lens is thicker in the middle than in the edge, and there are three types: biconvex, plano-convex, and concave-convex; a concave lens is thinner in the middle than in the edge, and there are three types: biconcave, plano-concave, and convex-concave.

[0045] Among them, the lenses are classified as follows: Convex lenses have the function of converging light, so they are also called "converging lenses" and "positive lenses". This type of lens can be divided into: 1. Double concave lens: a lens with two sides; 2. Plano-concave lens: a lens with one side concave and the other side flat; 3. Convex-concave lens: a lens with one side convex and one side concave. 4. Thin lens: a lens with a large thickness in the central part compared to the radius of curvature of its two sides. In the early days, cameras were only equipped with a convex lens, so they were called "single lenses". With the development of science and technology, modern lenses have several convex and concave lenses of different forms and functions to form a converging lens, called a "compound lens". The concave lens in the compound lens plays the role of correcting various aberrations.

[0046] It can be understood that in other embodiments, the refraction unit 201 can also be other types of media that can ensure different refractive indices, such as a prism, etc., which will not be described in detail here.

[0047] In the above embodiment, the refraction unit 201 is precisely determined to be a lens, which has a low cost and can accurately realize the gradient refraction of light.

[0048] In one embodiment, the plurality of refraction units 201 constituting the refraction assembly 20 are integrally formed.

[0049] Specifically, when there are a large number of refraction units, it is very time-consuming to install them one by one. Therefore, when the refraction situation can be determined, the plurality of refraction units 201 can be arranged to be integrally formed for easy use.

[0050] It can be understood that in some embodiments, the refraction unit can also be installed separately, which will not be described in detail here.

[0051] In the above embodiment, the multiple refraction units 201 are arranged to be integrally formed, which greatly facilitates the use by the user.

[0052] In one embodiment, the center of the light source 101 corresponds to the center of the refraction unit 201 that matches the light source 101 .

[0053] Specifically, when a lens is used, the refraction effect of light is best when the light source is located at the exact center of the lens. Therefore, the center of the light source 101 and the center of the refraction unit 201 are made to correspond to each other.

[0054] It can be understood that in other embodiments, the corresponding positions of the center of the light source 101 and the center of the refraction unit 201 can be determined according to actual conditions, which will not be described in detail here.

[0055] In the above embodiment, by making the center of the light source 101 correspond to the center of the refraction unit 201 that matches the light source 101, efficient refraction and utilization of light can be achieved.

[0056] In one embodiment, see Figure 3 As shown, Figure 3 It is a schematic diagram of the array distribution of light sources on the mounting carrier.

[0057] Specifically, the plurality of light sources 101 are distributed in an array on the mounting carrier 102. The array may be a "horizontal and vertical array" or a "circular array". In other embodiments, the type of array may be determined based on actual conditions, which will not be described in detail herein.

[0058] In the above embodiments, it is determined that the light sources are distributed in an array on the mounting carrier, so that the emission of light is more organized.

[0059] In one embodiment, see Figure 4 As shown, Figure 4 is a schematic diagram of the installation of the refractive component. The size of the refractive component 20 matches the size of the installation carrier 102. The refractive component 20 is sleeved on the installation carrier 102.

[0060] Specifically, in order to ensure the accuracy of light refraction and the aesthetics of the overall device, the size of the refraction component 20 matches the size of the mounting carrier 102 .

[0061] In the above embodiment, the size of the refraction component 20 is matched with the size of the mounting carrier 102, which can not only ensure the accuracy of light refraction but also ensure the overall aesthetics.

[0062] In one embodiment, the refraction component 20 is detachably connected to the mounting carrier 104 .

[0063] Specifically, the situations of detachable links are mainly as follows: 1. Threaded connection. Threaded connection is the most widely used detachable fixed connection form, mainly used for fastening parts. The threaded connectors used in general industrial products mainly include studs, bolts, screws and nuts. Studs and bolts are mainly used in some important structures with high connection requirements, and are used in conjunction with nuts. In order to prevent the connection from loosening due to vibration during operation, washers are often used in conjunction with the like. 2. Pin connection is a connection form that uses various pins to insert into the connection parts of the connected parts to achieve the connection, fixation or positioning of parts. Pin connection requires prefabricated holes (tapered holes or cylindrical holes) that match the pins at the connection parts of the parts. Tight fit is used for precise positioning and reliable fixation, and clearance fit is used for convenient assembly and disassembly. 3. Key connection. Keys are mainly used to connect shafts and parts on the shafts, transmit torque, and make them rotate synchronously with the shafts. There are flat keys, wedge keys, semicircular keys and splines. Key connections used for high-speed shafts should be designed with balance in mind and arranged symmetrically. In practical applications, a suitable detachable linking method can be selected according to the actual situation, and will not be described in detail here.

[0064] There are holes on both sides of the refraction component 20 and the mounting component 104 , and corresponding pins or keys can detachably connect the refraction component 20 to the mounting carrier 104 .

[0065] In the above embodiment, the refraction component 20 and the mounting carrier 104 are configured to be detachably connected, which is convenient for users to use.

[0066] In one embodiment, see Figure 5 As shown, Figure 5 It is a first refraction schematic diagram of the light emitting device, wherein the refractive indexes of the multiple lenses matching the light sources 101 in the same column are the same; and the refractive indexes of the multiple lenses matching the light sources 101 in different columns are different.

[0067] Specifically, when the refractive indexes of lenses in the same column are the same and the refractive indexes of lenses in different columns are different, the overall device can achieve gradient projection in the projection area of ​​the column.

[0068] In the above embodiment, by arranging lenses with different refractive indices in each column, gradient projection and focusing can be accurately achieved in the projection area of ​​the column.

[0069] In one embodiment, see Figure 6 As shown, Figure 6 3 is a second refraction schematic diagram of the light emitting device, wherein the refractive indexes of the multiple lenses matching the light sources 101 in the same row are the same; and the refractive indexes of the multiple lenses matching the light sources 101 in different rows are different.

[0070] Specifically, when the refractive indexes of lenses in the same row are the same and the refractive indexes of lenses in different rows are different, the overall device can achieve gradient projection in the projection area of ​​the row.

[0071] In the above embodiment, by arranging lenses with different refractive indices in each row, gradient projection can be accurately achieved in the projection area of ​​the row.

[0072] In one embodiment, the light source 101 at least includes high-power lamp beads.

[0073] Specifically, the light source 101 includes high-power lamp beads, which can realize lighting on the one hand, and more energy-concentrating on the other hand, and can be more widely used in bathroom lamp heating or other infrared physiotherapy fields, and the application scene can also be determined according to the actual situation, which will not be described one by one here.

[0074] In the above embodiment, the light source 101 is set to include high-power lamp beads, which can be more convenient for users to use.

[0075] In one embodiment, the light emitting device 1 is arranged on a ceiling appliance, and the ceiling appliance can be any one of a bathroom heater, a fresh air blower, and a ventilation fan.

[0076] In one embodiment, the lighting device 1 further includes a voice control component, which is connected to the light source component 10 and is used to control the light source component 10 to turn on under voice control induction.

[0077] The specific process is as follows:

[0078] 1. Sound collection: The voice control component first needs to collect sound signals through a built-in microphone or an external microphone. Sound signals are the energy of a mechanical wave propagating in the air, and the microphone can convert sound into a corresponding electrical signal.

[0079] 2. Sound processing: The collected sound signals need to be processed by the sound processing module. The sound processing module usually includes amplification, filtering, denoising and other links, aiming to extract effective sound information and filter out unnecessary interference signals.

[0080] 3. Voice recognition: The processed signal will be sent to the voice recognition algorithm for analysis and recognition. The voice recognition algorithm can determine whether the user's command is to turn on or off the light, adjust the brightness or change the color based on specific sound patterns or keywords.

[0081] 4. Control instruction generation: After the sound recognition is completed, the system will generate corresponding control instructions based on the recognition results. The control instructions can be switch signals, brightness adjustment values, or RGB color codes and other information.

[0082] 5. Lighting control: The generated control command will be sent to the light source assembly 10. The lighting control module will control the switching, brightness adjustment and color change of the light according to the information contained in the command.

[0083] 6. Feedback and response: Voice-controlled lights are usually equipped with feedback and response mechanisms. When the light changes, the user can be provided with corresponding feedback information through sound prompts, voice replies or light flashing, so that the user can understand the status of the light.

[0084] It should be noted that the working principle of the voice control component is not simply to control the switch of the light through the sound signal, but to realize the intelligent control of the light based on complex sound processing and sound recognition technology. At the same time, the lighting device 1 can also be combined with other smart devices, such as voice assistants, smart home systems, etc., to realize more advanced intelligent control functions.

[0085] In one embodiment, the mounting carrier 102 includes a solar charging panel for providing backup power for the light source 101 .

[0086] The solar charging panel powers the light bulb by converting solar energy into electrical energy, and storing the electrical energy through the charging panel to supply the light source 101. The working principle and process of the solar charging panel power supply will be described in detail below.

[0087] 1. Photovoltaic effect: Solar charging panels use the photovoltaic effect, which is the physical phenomenon of converting sunlight into electrical energy. Sunlight is an electromagnetic wave composed of photons of a certain frequency and energy. When photons shine on the surface of photovoltaic cells, they will stimulate the electrons in the semiconductor materials in the photovoltaic cells to jump from the valence band to the conduction band, generating current; photovoltaic cells, the core component of solar charging panels is photovoltaic cells, which are composed of multiple photovoltaic cells. Photovoltaic cells are usually made of high-purity silicon or other semiconductor materials, with positive and negative poles, forming an electric field. When sunlight shines on photovoltaic cells, the light energy is absorbed by the photovoltaic cells and converted into electrical energy.

[0088] 2. Charge controller: Solar charging panels are also equipped with a charge controller, which is used to monitor and adjust the battery's charging status. The charge controller can control the output voltage and current of the photovoltaic cell to ensure safe charging and charging efficiency of the battery.

[0089] 3. Battery: The electricity from the solar panel will be stored in the battery after being charged by the charge controller; the battery is usually a rechargeable chemical battery that can store electricity in a chemical form. The capacity of the battery determines the amount of electricity stored.

[0090] 4. Inverter: When the light bulb needs to be powered, the DC power stored in the battery needs to be converted into AC power. This is when the inverter comes into play. The inverter can convert DC power into AC power that meets the working requirements of the light source 101 to supply the light bulb.

[0091] 5. Power supply: The AC power converted by the inverter can be directly supplied to the light source 101. The light bulb generates heat energy and light energy according to the flow of current, thereby achieving a lighting effect.

[0092] The whole process can be summarized as follows: the solar charging panel converts solar energy into electrical energy through the photovoltaic effect, and stores the electrical energy in the battery through the charging controller. When power is needed, the inverter converts the DC power in the battery into AC power for the light source 101 to use.

[0093] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
