Description

Technical Field

[0001] This utility model relates to the field of comprehensive utilization of solar energy, specifically to a structure that combines solar energy conversion, energy storage, and lighting. Background Technology

[0002] Currently, technologies for utilizing sunlight for lighting mainly follow two paths. The first is the light-guiding lighting system, which uses physical light-guiding components such as light guides and light collectors to directly transmit outdoor natural light indoors. Its core advantages are no energy conversion loss and superior light quality, effectively reducing reliance on mains power during the day; however, it has significant limitations, operating only during periods of natural light and completely failing to provide illumination at night or on cloudy or rainy days, making it difficult to meet the need for continuous all-weather lighting. The second is the photovoltaic (PV) lighting system, which converts light energy into electrical energy through solar panels and stores it in batteries to drive LED lights. This type of system relies on the capacity of the energy storage battery, suffers from short battery life during continuous cloudy or rainy days, and experiences energy conversion losses during the photoelectric conversion-storage-discharge lighting process.

[0003] In existing technologies, there are attempts to combine the two, but most of them are limited to the simple superposition of functional modules, resulting in a large overall system size and low integration. This not only makes installation and maintenance inconvenient, but also fails to achieve efficient and coordinated energy allocation and comprehensive utilization. Utility Model Content

[0004] The purpose of this invention is to provide a structure that combines solar energy conversion and storage with lighting. Through innovative optical structure and system integration design, it solves the problems of existing solar lighting solutions, such as single function, low integration, and difficulty in meeting the needs of continuous all-weather lighting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A structure combining solar energy conversion and storage with lighting includes a solar energy conversion device (1), a flexible optical fiber (2), a wire (3), a rechargeable battery (4), a switch (5), and a lighting lamp (6). The solar energy conversion device (1) can simultaneously utilize and convert the received sunlight (7) into light energy. The light incident end of the optical fiber (2) is coupled to the light output end of the solar energy conversion device (1), and the light emitting end of the optical fiber (2) is coupled to the light incident end of the lighting lamp (6), forming a light-guiding lighting path. One section of the wire (3) connects the power output end of the solar energy conversion device (1) to the power input end of the battery (4), and the other section of the wire (3) connects the power output end of the battery (4) to the power input end of the lighting lamp (6). A switch (5) is connected in series between the battery (4) and the lighting lamp (6), forming a photoelectric conversion charging circuit and a controllable discharge lighting circuit.

[0007] The solar energy conversion device (1) includes a solar energy conversion unit consisting of a Fresnel lens (101), a solar energy conversion unit housing (102), a solar panel (103), and an optical fiber interface (105); the solar energy conversion unit housing (102) has an outer square and inner circular cavity configuration. The outer square structure facilitates the array installation of multiple solar energy conversion units, and the inner circular structure is coated with a high reflectivity material layer to facilitate light reflection and convergence; the top opening of the solar energy conversion unit housing (102) is provided with a Fresnel lens fixing groove (104), and the Fresnel lens (101) is fixed to the top opening of the solar energy conversion unit housing (102) through the Fresnel lens fixing groove (104); the solar energy conversion device (1) is composed of multiple solar energy conversion unit arrays;

[0008] The solar conversion unit housing (102) has a solar panel mounting groove (106) near the bottom. The solar panel (103) is located inside the solar conversion unit housing (102) through the solar panel mounting groove (106). The solar panel (103) has a through hole in the center, and a tubular optical fiber interface (105) is provided on the lower surface of the solar panel at the through hole. The solar panel (103) is equipped with a solar panel wire (107), which is used to connect to the wire (3). The optical fiber interface (105) The upper end face of the fiber optic connector (105) is fixed to the solar panel (103), and the fiber optic connector (105) is coaxial with the central through hole of the solar panel (103). When the fiber optic connector (105) is connected to the light incident end of the fiber optic (2), the light incident end of the fiber optic (2) is further away from the Fresnel lens (101) than the solar panel (103), so that while some light shines on the solar panel (103), some light can still pass through the central through hole of the solar panel to shine on the incident end face of the fiber optic (2); the fiber optic connector (105) is used to connect the flexible fiber optic (2).

[0009] The lighting lamp (6) includes a light shield (601), an optical fiber fixing hole (602), an LED module (603), and a lighting lamp housing (604); the lighting lamp housing (604) is a cylindrical shell with one open end and a rounded corner transition at the top outer edge; the light shield (601) is fixed inside the lighting lamp housing (604) and is a bowl-shaped reflector with the bottom of the bowl-shaped structure bent towards the center of the lighting lamp housing (604); the center of the light shield (601) has a lamp interface (605) with an internal thread on the inner wall; the LED module (603) 03) The LED module (603) is detachably fixed to the light shield (601) by engaging with the lamp interface (605) via an external thread. An internal wire (606) is provided inside the LED module (603) for connecting with the wire (3). At the same time, the lighting housing (604) is also provided with an optical fiber fixing hole (602). The optical fiber fixing hole (602) is used to fix the light-emitting end of the optical fiber (2). The optical fiber fixing hole (602) is a cylindrical through hole with an inner diameter matching the outer diameter of the optical fiber (2). The light extends through the light-emitting end of the optical fiber (2) into the cavity of the light shield (604) to achieve light-guiding illumination. The optical fiber fixing hole (602) consists of multiple circular holes evenly located on the outer periphery of the lamp interface (605).

[0010] The battery (4) is a lithium-ion battery, and the switch (5) is a manual switch that can control the on / off state of the discharge lighting circuit according to the ambient light intensity, thereby realizing the switching between light guide lighting and LED lighting modes.

[0011] The solar energy conversion device consists of multiple, for example, eight, solar energy conversion units, which are connected to a rechargeable battery (4) via wires (3) for energy storage, and are also connected to a lighting lamp (6) via flexible optical fibers (2).

[0012] During the day, sunlight (7) is focused by Fresnel lens (101), and the peripheral light is converted into electrical energy by solar panel (103) and stored in battery (4) through wire (3). The central light passes through the central hole of solar panel (103) and is transmitted to lighting lamp (6) through optical fiber (2) to achieve light guiding lighting. At night or when there is insufficient light, switch (5) controls the discharge lighting circuit to be turned on, and battery (4) supplies power to LED module (603) to achieve discharge lighting.

[0013] The incident end of the flexible optical fiber is coupled to the optical fiber interface of the solar energy conversion device, and its output end extends and is fixed inside the lighting lamp, thereby forming a light guide lighting path from the light collector to the lamp.

[0014] The power output terminal of the solar panel is connected to the battery via a wire to form a photoelectric conversion charging circuit. The power output terminal of the battery is connected to the LED module in the lighting lamp via a wire and a switch to form a controllable discharge lighting circuit.

[0015] Furthermore, the vertical distance between the Fresnel lens and the bottom of the solar energy conversion unit housing is precisely set, so that after the incident sunlight is focused by the Fresnel lens, the peripheral light falls on the surface of the solar panel to achieve photoelectric conversion, and the central light can fall on the optical fiber incident end face through the central through hole of the solar panel to achieve light transmission. Based on this, the device can be used for photoelectric conversion and light guiding illumination simultaneously.

[0016] Furthermore, the switch can be selected as manual or photosensitive automatic control mode, and is used to automatically or manually switch between light guide lighting and LED lighting modes according to the ambient light intensity conditions.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Through the innovative "one light, two uses" design, flexible optical fiber and solar panel are integrated into the same light collection barrel, which simultaneously performs light guiding and lighting and photoelectric conversion. This fundamentally avoids the structural redundancy caused by module stacking and realizes the integration and unification of the system.

[0019] 2. Using the central area at the bottom of the lighting fixture as the natural light inlet, the LED modules are distributed in a ring around the fiber optic output end face, which truly saves space, avoids the problem of having to replace the lighting fixture when changing scenes, and realizes deep synergy of lighting functions.

[0020] 3. During the day, the system prioritizes low-energy-loss light-guiding lighting, which reduces carbon emissions and allows people working in enclosed buildings or underground parking lots to bask in the sunlight. At the same time, the device can convert excess solar energy into electrical energy through the photovoltaic effect for storage, achieving efficient and synergistic utilization of solar energy.

[0021] 4. During the day, natural light is directly guided through optical fibers to achieve extremely low-energy solar lighting. At night or when there is insufficient light, it can automatically switch to battery-powered LED lighting mode, solving the problem that traditional light guide systems cannot work at night and achieving continuous lighting all day long.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] This utility model provides a device that combines solar energy conversion and storage with lighting. The device comprises: a solar energy conversion device (1), a flexible optical fiber (2), a wire (3), a battery (4), a switch (5), and a lighting lamp (6). The solar energy conversion device (1) can simultaneously perform light-guiding lighting and photoelectric conversion on the received sunlight. The light-incident end of the optical fiber (2) is coupled to the light-output end of the solar energy conversion device (1), and its light-outceasing end extends to and is coupled to the light-incident end of the lighting lamp (6), thereby forming a light-guiding transmission path.

A through hole is provided, and an optical fiber interface (105) is arranged below the through hole. The axis of the optical fiber interface (105) is completely coincident with the optical axis of the Fresnel lens (101). The horizontal plane where the lower end face of the optical fiber interface (105) is located is set below the horizontal plane where the solar panel (103) is located, so that the optical fiber light incident end is farther away from the Fresnel lens (101) than the solar panel (103), so that the light is focused. While some light shines on the solar panel (103), some light can still pass through the central through hole of the solar panel to shine on the incident end face of the optical fiber (2). The incident end of the optical fiber (2) is coupled to the optical fiber interface (105). The power output end of the solar panel (103) is connected to the power input end of the battery (4) through the wire (107) of the solar panel. In order to obtain the best light energy utilization efficiency, the vertical distance between the Fresnel lens (101) and the plane where the solar panel (103) is located is precisely set.

[0032] like Figure 4 , 5As shown, the lighting lamp (6) comprises: a light shield (601), an optical fiber fixing hole (602), an LED module (603), and a lighting lamp housing (604); the most prominent feature of the lighting lamp (6) is that it has dual functions of light illumination and electric illumination; the lighting lamp housing (604) is constructed as a cylindrical housing structure with a rounded corner transition design on its top outer edge, the purpose of which is to reduce the risk of injury during collision; the light shield (601) is constructed as a hollow hemispherical shell, which is embedded in the lighting lamp housing (604); the center of the light shield (601) is provided with an annular optical fiber fixing hole (602), which is constructed as a cylindrical through hole, the inner diameter of which matches the outer diameter of the optical fiber (2), thereby achieving stable fixation of the emitting end of the optical fiber (2); the light extends through the emitting end of the optical fiber (2) into the cavity formed by the light shield (601) to achieve light illumination. The light shield (601) has a lamp interface (605) at its center, and the inner wall of the lamp interface (605) is machined with internal threads. The LED module (603) is fixedly installed on the light shield (601) in a detachable manner by the external threads of its lamp head part cooperating with the internal threads of the lamp interface (605) to realize electric lighting. The electrodes of the LED module (603) are connected to the wire (3) through the lamp internal wire (606), and then connected to the power output terminal of the storage battery (4) through the switch (5).

[0033] Furthermore, the focal position of the Fresnel lens (101) falls exactly on the plane where the incident end of the optical fiber (2) is located.

[0034] The working principle of this utility model is as follows: During the day, outdoor sunlight is focused by a Fresnel lens (101) to form a light spot. The light from the center of the light spot is directly transmitted through the optical fiber (2) to the cavity formed by the light shield (604) of the lighting lamp (6), achieving extremely low energy consumption daytime lighting. The light from the periphery of the focused light spot is reflected by the high-reflectivity cavity and then irradiates the surface of the solar panel (103) for photoelectric conversion. Subsequently, the electrical energy is stored in the battery (4) through the wire (3). At night or when there is insufficient light, the switch (5) is closed, and the electrical energy stored in the battery (4) drives the LED module (603) to work through the discharge circuit to meet the continuous lighting needs.
