[0027] Traditional skylight designs typically employ a side-enclosed structure. While this provides excellent lighting, it lacks ventilation, leading to heat buildup in summer and increased indoor temperature, thus affecting comfort. To address this issue, it is necessary to design a new ventilation structure for skylights, optimizing the structural design to improve indoor comfort.

[0028] In view of this, this application proposes a lighting and ventilation structure.

[0029] In the first embodiment of this application, reference is made to Figures 1 to 2 The above-mentioned lighting and ventilation structure includes: a lighting strip 1 and a ventilation structure 2. The lighting strip 1 is installed on the roof, and the ventilation structure 2 is installed on the side of the lighting strip 1. The ventilation structure 2 includes an L-shaped channel 210. The channel 210 includes a horizontal part 211 and a vertical part 212. The opening of the horizontal part 211 communicates with the interior of the house, and the opening of the vertical part 212 communicates with the exterior of the house. The opening of the vertical part 212 faces downward.

[0030] Specifically, in summer, the indoor air rises to the roof after being heated, and enters the L-shaped channel 210 through the horizontal opening 211, and is discharged outdoors through the vertical opening 212. At the same time, outdoor light enters the room through the skylight strip 1 on the roof. The vertical opening 212 faces downwards, which can prevent rainwater from directly entering the channel 210. This design utilizes the principle of thermal pressure ventilation, combined with the directional design of the L-shaped channel 210, to form a rainproof ventilation path on the side of the skylight strip 1, realizing the integration of lighting and ventilation functions. The structure is compact and improves indoor comfort.

[0031] In this embodiment, a cover plate 220 is provided at the opening of the horizontal part 211. The upper end of the cover plate 220 is rotatably connected to the inner wall of the channel 210 through a rotating shaft 221. The rotating shaft 221 is installed on the upper end of the cover plate 220, so that the cover plate 220 forms an upward-suspension flap structure. The cover plate 220 rotates around the rotating shaft 221 as the fulcrum. When the hot air rises and the indoor air pressure increases, a pressure difference will be formed on both sides of the cover plate 220. The air pressure will push the cover plate 220 to rotate upward around the rotating shaft 221 and open. When ventilation is not required, the cover plate 220 closes automatically under the action of gravity, which can effectively block dust and debris from entering the room.

[0032] In this embodiment, the cover plate 220 is a plate-shaped structure made of elastic lightweight material, which can be made of polypropylene, polyethylene, aluminum alloy or other composite materials. By utilizing the deformation characteristics and lightweight characteristics of the elastic material, the threshold for ventilation activation is reduced, so that the cover plate 220 can be opened automatically under weak airflow. Moreover, no additional power is required, and automatic ventilation is achieved by relying on natural air pressure difference, which saves energy and has low maintenance costs.

[0033] In this embodiment, a magnetic attraction structure (not shown in the figure) is provided between the lower end of the cover plate 220 and the inner wall of the channel 210. The magnetic attraction structure includes a first magnetic element and a second magnetic element. The first magnetic element is disposed on the cover plate 220, and the second magnetic element is disposed on the inner wall of the channel 210. The cover plate 220 is fixed by the attraction of a permanent magnet to form a magnetic locking structure, which enhances the sealing performance when closed. When the cover plate 220 is closed, the first magnetic element and the second magnetic element are attracted to each other, keeping the cover plate 220 tightly closed. When it needs to be opened, the airflow or air pressure overcomes the magnetic force, causing the cover plate 220 to separate from the channel 210.

[0034] In this embodiment, grooves 222 are provided vertically on the inner wall of the channel 210 corresponding to the pivot 221 of the cover plate 220. A slider 223 is slidably disposed in the grooves 222. The pivot 221 is rotatably mounted on the slider 223. An arc-shaped expansion member 224 is provided between the slider 223 and the lower end face of the groove 222. The expansion member 224 expands when heated and contracts when cooled. The expansion member 224 can be made of shape memory alloy or aluminum. In summer, when the indoor temperature rises, the expansion member 224 expands due to heat, pushing the slider 223 along the groove 222. 22 moves upward, driving the cover plate 220 upward via the rotating shaft 221, causing the magnetic attraction structure at the lower end of the cover plate 220 to separate; a small air pressure or airflow can push the cover plate 220 open; in winter, when the temperature drops, the expansion element 224 contracts, the slider 223 moves downward, and the cover plate 220 closes under the action of gravity and magnetic force, improving the indoor heat preservation effect; utilizing the principle of thermal expansion and contraction, the mechanical structure is driven by the volume change of the expansion element 224 to achieve temperature-sensing automatic ventilation, without the need for electricity or manual intervention, and automatically adjusts the ventilation according to the indoor temperature.

[0035] In this embodiment, the surface of the first magnetic component corresponding to the second magnetic component is set as a convex arc surface, and the surface of the second magnetic core component corresponding to the first magnetic component is set as a concave arc surface (existing technology, refer to the structure of household anti-collision door catches); when the cover plate 220 is closed, the convex first magnetic component and the concave second magnetic component fit together to form an arc surface seal; the arc surface fit increases the contact area of ​​the magnetic components and enhances the magnetic adsorption strength; at the same time, when the cover plate 220 moves upward under the push of the expansion 224, even if the movement distance is very small, it will cause the arc surface between the first magnetic component and the second magnetic component to be misaligned, thereby reducing the magnetism or causing the magnetism to fail. In summer, the airflow or air pressure can push the cover plate 220 to open.

[0036] In this embodiment, an insect-blocking plate 230 is provided at the opening of the vertical part 212. The insect-blocking plate 230 covers the opening of the vertical part 212 and is used to block mosquitoes. The insect-blocking plate 230 is composed of an insect-blocking net and a frame. A reinforcing rod can also be provided in the middle of the frame. The frame and the reinforcing rod can also support the opening of the vertical part 212. The insect-blocking plate 230 covers the opening of the vertical part 212, allowing air to flow through the pores, but blocking mosquitoes, birds and other insects from entering the passage 210, preventing outdoor mosquitoes and debris from entering the room and keeping the environment clean.

[0037] In the second embodiment of this application, reference is made to Figure 3 Multiple ventilation structures 2 are provided, and the multiple ventilation structures 2 are symmetrically arranged on both sides of the lighting strip 1. The lighting strip 1 includes a lighting panel 110. The lighting panel 110 has a U-shaped cross-section and is an integrally formed structure. The two side panels of the lighting panel 110 extend downward to the outside of the ventilation structure 2. The multiple ventilation structures 2 are symmetrically distributed to form a uniform air circulation path. The U-shaped lighting panel 110 extends to the outside of the ventilation structure 2 on both sides, which can block rainwater and protect the ventilation opening.

[0038] Specifically, the skylight 1 and the ventilation structure 2 are both installed on the roof via the support structure 3. The support components include beams, angle steel, purlins, etc., which can be installed and supported according to the usage. Thermal insulation cotton 4 is also installed between the support structures 3. The support structure 3 fixes the skylight 1 and the ventilation structure 2 to ensure stable installation. The thermal insulation cotton 4 is filled between the support structures 3 to block the transfer of heat between the indoor and outdoor spaces.

[0039] This technical solution incorporates a skylight and ventilation structure. The skylight is mounted on the roof, and the ventilation structure is located on the side of the skylight. The ventilation structure includes an L-shaped channel with a horizontal and a vertical section. The horizontal opening connects to the interior, while the vertical opening connects to the exterior, with the vertical opening facing downwards. In summer, heated indoor air rises to the roof and enters the L-shaped channel through the horizontal opening, then exits outdoors through the vertical opening. Simultaneously, outdoor sunlight enters the interior through the skylight on the roof. The downward-facing vertical opening prevents rainwater from directly entering the channel. This design utilizes the principle of thermal pressure ventilation, combined with the directional design of the L-shaped channel, to create a rainproof ventilation path on the side of the skylight, integrating lighting and ventilation functions. The structure is compact and improves indoor comfort.
