Description

Technical Field

[0001] This utility model relates to the field of architectural lighting technology, and in particular to a modular integrated ventilation and lighting device. Background Technology

[0002] With economic development, building energy consumption now accounts for one-third of total energy consumption. Rapid urbanization has made building energy consumption a major source of energy consumption. For enclosed buildings that cannot be directly lit (such as basements, underground garages, processing workshops, shopping malls, etc.), lighting fixtures or daylighting devices are usually used for illumination. This process wastes electricity and poses certain safety hazards. Furthermore, electric lights can only provide illumination of a single wavelength, which can easily cause visual fatigue for customers or users over long periods. Therefore, based on green and environmentally friendly requirements, existing technologies often use tubular daylighting systems to guide light into the interiors of buildings, such as basements, which are difficult to receive natural light. A tubular daylighting system is a system that collects natural light and transmits it through pipes to the interior for natural lighting.

[0003] However, existing light pipe systems are complicated to install and difficult to ventilate. They also require high-quality construction techniques. Deviations in the construction process can result in only a few light-receiving surfaces being usable during use. In situations with poor natural light conditions, such as early morning, late evening, or cloudy days, it is difficult to collect natural light, leading to insufficient lighting efficiency.

[0004] Therefore, there is a need for a modular integrated ventilation and lighting device that is easy to install, has a simple structure, and is easy to maintain. Summary of the Invention

[0005] The main purpose of this utility model is to provide a modular integrated ventilation and lighting device, which aims to solve the problems of low working efficiency and difficulty in maintenance of existing lighting devices during production and installation.

[0006] To achieve the above objectives, this utility model proposes a modular integrated ventilation and lighting device, which is applied inside a building and includes:

One end of the electric push rod is connected to the output end of the motor, and the other end of the electric push rod is connected to the ventilation baffle.

[0013] Preferably, the baffle assembly further includes a limiting member disposed between the plurality of ventilation baffles.

[0016] This utility model discloses a modular integrated ventilation and lighting device. A supporting sleeve assembly is integrally fitted onto a lighting component, and baffle assemblies are installed around the lighting component. The opening angle and distance of the baffles can be adjusted according to different weather conditions. The supporting sleeve assembly also contains ventilation ducts for natural ventilation.

[0027] In existing technologies, basements, underground garages, and other enclosed or semi-enclosed buildings cannot meet the requirements for sunlight, and the environment is humid and has poor air circulation, which can easily lead to the growth of microorganisms and excessive air pollutants.

[0028] Based on this, such as Figures 1-3 As shown, this utility model proposes a modular integrated ventilation and lighting device 1000 for use in buildings, comprising: a lighting component 100, which includes a light-collecting cover 110, a light guide tube 120, and a diffuse reflector 130, wherein the light-collecting cover 110 and the diffuse reflector 130 are respectively disposed at both ends of the light guide tube 120, the light-collecting cover 110 passes through the top of the building and extends to the external environment, and the diffuse reflector 130 is disposed inside the building; and a support sleeve assembly 200, which includes a ventilation sleeve 210 and a support tube 220 for ventilation. A ventilation cavity is formed between the sleeve 210 and the support tube 220. The ventilation sleeve 210 and the support tube 220 are coaxially sleeved on the outside of the light guide tube 120. The baffle assembly 300 includes a ventilation baffle 310 and a driving device 320. There are multiple ventilation baffles 310, which are arranged around the light collecting cover 110. The ventilation baffles 310 and the light collecting cover 110 are movably connected. The driving device 320 is disposed in the ventilation cavity and fixedly connected to the support tube 220. The driving assembly is connected to the ventilation baffle 310.

[0029] The modular integrated ventilation and lighting device 1000 proposed in this utility model also includes a light sensor, a rain sensor, and a controller. The light sensor and rain sensor identify whether the current external weather is sunny or rainy. When the weather is sunny, the controller controls the drive device 320 to move the ventilation baffle 310 relative to the light-collecting cover 110, increasing the ventilation area. The light-collecting cover 110 uses transmission and refraction to guide natural light from outside the building into the light guide tube 120. The light guide tube 120 is a metal pipe with a smooth inner wall and a reflectivity >99.7% to ensure efficient long-distance light transmission. The diffuser plate 130 is used to evenly disperse the focused natural light into the room. It is understood that, depending on the actual environmental requirements, the light guide tube 120 can be a long straight tube or a curved tube obtained by combining bent tubes, extension tubes, etc. In detail, in this embodiment, the light collecting cover 110 is made of tempered laminated glass to form a hemispherical shell, and the light guide tube 120 is made of 0.4mm-0.6mm thick aluminum material. The inner wall of the light guide tube 120 is covered with a reflective film to ensure the stability of light transmission. At the same time, it can be adjusted and bent to match the building structure, reducing the restrictions of the building structure.

[0030] In this embodiment, there are two ventilation baffles 310, which are mirror images of each other on both sides of the light-collecting cover 110. Under different weather conditions, the two ventilation baffles 310 can be opened or closed relative to the light-collecting cover 110. For example, in sunny weather, the ventilation baffles 310 are opened by rotating relative to the light-collecting cover 110 via the drive device 320, providing more air inlets compared to the closed state, increasing the ventilation area and improving ventilation efficiency. In rainy weather, the ventilation baffles 310 are closed relative to the light-collecting cover 110 via the drive device 320, retaining only a small number of air inlets, reducing the number of air inlets and the ventilation area, effectively preventing rainwater or other debris from entering the device through the air inlets.

[0031] More specifically, an air pump 221 can be added inside the support pipe 220 to exchange indoor air with outdoor air, preventing the long-term accumulation of toxic and harmful gases generated in the indoor air. Both the ventilation sleeve 210 and the support pipe 220 are circular pipes, and are coaxially sleeved around the light guide pipe 120. A cavity is formed between the ventilation sleeve 210 and the support pipe 220, which is a ventilation cavity. The air pump 221 is connected to this ventilation cavity to exchange indoor air with outdoor air, thereby achieving ventilation and heat dissipation.

[0032] In one embodiment, the ventilation baffle 310 is provided with an air inlet 311 and a ventilation slot 312. The air inlet 311 is located on the side of the ventilation baffle 310 away from the light collecting cover 110. The ventilation slot 312 extends along the length of the ventilation baffle 310 and penetrates the interior of the ventilation baffle 310. The two ends of the ventilation slot 312 are respectively connected to the air inlet 311 and the ventilation cavity.

[0033] In this embodiment, the ventilation baffle 310 has a semi-circular structure. An air inlet 311 is located on the side of the ventilation baffle 310 away from the light-collecting cover 110. A ventilation groove 312 penetrates the ventilation baffle 310. The air inlet 311 communicates with the ventilation cavity through the ventilation groove 312. When the ventilation baffle 310 is closed, airflow can be guided through the ventilation groove 312, ensuring adequate ventilation inside the building. It is understood that the air inlet 311 is also equipped with a rainproof plate 313. The rainproof plate 313 is an engineering plastic plate set at an angle to the opening direction of the air inlet 311, preventing rainwater or other debris from directly entering the ventilation groove 312 through the air inlet 311.

[0034] In one embodiment, the ventilation baffle 310 further includes a solar panel 314 and an energy storage battery 315. The solar panel 314 is disposed at the top of the ventilation baffle 310, and the energy storage battery 315 is disposed in the support tube 220 near the radial inner side of the ventilation baffle 310. The energy storage battery 315 is electrically connected to the solar panel 314.

[0035] In this embodiment, the solar panel 314 is fixedly installed on the top of the ventilation baffle 310. When the angle of direct sunlight moves on a sunny day, the ventilation baffle 310 drives the solar panel 314 to move, so that the solar panel 314 can stably convert solar energy into electrical energy. The solar panel 314 then transmits the electrical energy to the energy storage battery 315, which is used to power the drive device 320, thereby improving the energy self-sufficiency level of the modular ventilation and lighting integrated device 1000 and achieving a green and environmentally friendly effect.

[0036] In one embodiment, the drive device 320 further includes a motor 321 and an electric push rod 322. The motor 321 is disposed inside the support tube 220 and electrically connected to the energy storage battery 315. One end of the electric push rod 322 is connected to the output end of the motor 321, and the other end of the electric push rod 322 is connected to the ventilation baffle 310.

[0037] In this embodiment, there are four electric actuators 322. These four actuators are respectively positioned on both sides of the ventilation baffle 310 and hinged to it via universal joints. The other end of each actuator 322 is connected to the output end of the motor 321. The extension and retraction of the four actuators 322 control the displacement angle and amount of the ventilation baffle 310. The motor 321 is housed within the support tube 220 and electrically connected to the energy storage battery 315 to absorb the electrical energy generated by the solar panel 314 and supply it to the input end of the motor 321.

[0038] In another embodiment, the drive device 320 further includes a horizontal push rod disposed between the two ventilation baffles 310. The horizontal push rod is used to push the two ventilation baffles 310 horizontally apart, which facilitates the separation and retraction of the ventilation baffles 310.

[0039] In one embodiment, the baffle assembly 300 further includes a limiting member 330, which is disposed between a plurality of ventilation baffles 310. The ventilation baffles 310 are provided with limiting grooves 316 around the light collecting cover 110. The limiting member 330 and the limiting grooves 316 are slidably connected. The two ends of the limiting member 330 are provided with limiting pins 331, and the two ends of the limiting grooves 316 are provided with slots 317 corresponding to the limiting pins 331.

[0040] In this embodiment, each ventilation baffle 310 has two limiting grooves 316, which are respectively set on the left and right sides of the ventilation baffle 310. The number of limiting members 330 corresponding to the limiting grooves 316 is set to two. The two limiting members 330 are set on the left and right sides of the light collecting cover 110 and are set in accordance with the positions of the limiting grooves 316. The limiting component 330 is horizontally positioned between the two ventilation baffles 310. Each of the left and right ends of the two limiting components 330 is provided with a limiting pin 331. The limiting slide 316 is provided with a slot 317 corresponding to the limiting pin 331. An elastic element is provided on the inner side of the slot 317. The limiting pin 331 and the limiting slide 316 are slidably connected. When the limiting pin 331 moves to the slot 317, the limiting pin 331 is fixed by interference fit through the elastic element in the slot 317. The distance between the slots 317 at both ends of the limiting slide 316 forms a moving distance threshold for the limiting pin 331 relative to the limiting slide 316, so that the two opposing ventilation baffles 310 have a maximum distance away and a minimum distance close together, ensuring that the ventilation baffles 310 avoid the risk of derailment during movement.

[0041] In one embodiment, the modular ventilation and lighting integrated device 1000 further includes a dust filter cover 400, which has a rectangular mesh structure and anti-slip strips on its periphery. The top of the ventilation sleeve 210 is provided with a mounting groove 211, and the dust filter cover 400 is fixed by the interference fit between the anti-slip strips and the mounting groove 211.

[0042] It is understood that the dust filter hood 400 is used to filter dust and debris. In this example, the mesh size of the dust filter hood 400 is 20 mesh. In another embodiment, the mesh size can be adjusted and replaced between 4 and 25 mesh according to actual needs. In this embodiment, the dust filter hood 400 is a circular structure coaxial with the light collecting cover 110 and is fitted on the top of the ventilation sleeve 210. The circumference of the dust filter hood 400 is also provided with a high-elastic rubber strip as an elastic element. The top of the ventilation sleeve 210 is provided with a mounting groove 211 corresponding to the dust filter hood 400. The mounting groove 211 is also provided with a high-elastic rubber strip as an elastic element. When the dust filter hood 400 is set in the ventilation sleeve 210, the two elastic elements are interference-fitted to achieve fixation. At the same time, the two elastic elements can also form a waterproof structure to prevent condensation or other external liquid sources from corroding the periphery of the dust filter hood 400 and causing damage to the dust filter hood 400.

[0043] In one embodiment, the light-collecting cover 110 has a hemispherical structure, and the ventilation baffle 310 is provided with an avoidance recess 318. The avoidance recess 318 is provided on the side of the ventilation baffle 310 near the light-collecting cover 110. The avoidance recess 318 is arc-shaped and the curvature matches the outer contour of the light-collecting cover 110.

[0044] In this embodiment, the ventilation baffle 310 is a semi-circular structure with a relief recess 318 on the side near the light collecting cover 110. The relief recess 318 is an arc-shaped recess, and the curvature of the relief recess 318 is adapted to the outer contour of the light collecting cover 110. When the ventilation baffle 310 moves, the relief recess 318 is used to avoid the light collecting cover 110, so as to prevent the ventilation baffle 310 from colliding with the light collecting cover 110 and improve the working stability of this utility model.

[0045] This utility model discloses a modular integrated ventilation and lighting device. It incorporates a lighting component with a supporting sleeve assembly over it. The supporting sleeve assembly also features a movable ventilation baffle, which can be adjusted in angle according to different weather conditions. The baffle can be opened relative to the light-collecting cover on sunny days to enhance ventilation or closed on rainy days to protect the internal structure. This utility model solves indoor lighting problems without an external power source, saving 8-10 hours of daytime lighting electricity. As a one-time investment energy-saving product, it has a significant advantage in terms of return on investment. Furthermore, its simple structure makes it easy to maintain and reduces construction costs.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
