Description

Technical Field

[0001] This invention relates to the field of ceiling light technology, specifically to an indoor ceiling light with moisture-proof function. Background Technology

[0002] Ceiling lights, as a basic indoor lighting fixture, are widely used in homes, offices, shopping malls, corridors, and stairwells due to their easy installation, compact structure, and uniform light distribution. Their basic structure typically includes a cover (lampshade), a light source (such as an LED module), a driver, a heat sink, and a base for mounting to the ceiling. The main issues are as follows: Although ceiling lights fit snugly against the ceiling, their interior is not completely sealed. Because the light generates heat during operation, the temperature drops after operation, causing the internal air to contract and create negative pressure. This allows humid air from outside to be "drawn" into the light body through tiny gaps. When the light is restarted or the ambient temperature changes, the drawn-in moisture condenses into water droplets on the cooler inner walls of the lampshade, the light source board, or the driver, forming water droplets. For mainstream LED light sources, these condensed water droplets falling onto the LED chips or PCB board can cause short circuits, oxidation, and corrosion of the LED chips, leading to accelerated light decay, flickering, or even complete failure.

[0003] Some products attempt to achieve physical sealing by adding sealing rings or other methods. However, overly tight seals can hinder the dissipation of heat generated during lamp operation, leading to heat buildup, which in turn accelerates LED light decay and power supply aging. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides the following technical solution: an indoor ceiling light with moisture-proof function, comprising a rotating base, an adjustment component fixedly connected to the side of the rotating base, a lighting lamp fixedly connected to the bottom of the adjustment component, absorbent cotton fixedly connected to the inner wall of the lighting lamp, a guide top fixedly connected to the bottom of the rotating base, a limiting component adapted to the guide top fixedly connected to the top of the rotating base away from the center, a rotating handle fixedly connected to the inner side of the rotating base, and a fixing component fixedly connected to the top of the rotating base, the rotating base being used to rotate the device. The system supports the light fixture, provides illumination, and adjusts and locks the position of the light to stabilize the lighting in different locations. Absorbent cotton absorbs water vapor from inside the light fixture, preventing it from affecting the illumination. A guide top, in conjunction with the fixture, secures and guides the water vapor, preventing its accumulation. A rotating handle drives the base to rotate, engaging with the fixing components for easy installation and adjustment. The fixing components facilitate quick installation and removal of the ceiling light.

[0005] The adjusting assembly includes a sliding frame with a limiting hole at the bottom of its inner wall. A sliding top plate is slidably connected to the top of the inner wall of the sliding frame. A fixed end of a spring slide rod is fixedly connected to the bottom of the sliding top plate. A movable plate is sleeved and slidably connected to the movable end of the spring slide rod. A limiting strip adapted to the limiting hole is fixedly connected to the bottom of the movable plate. A connecting frame is fixedly connected to the bottom of the movable plate. The side of the sliding frame is fixedly connected to the side of the rotating base. The bottom of the connecting frame is fixedly connected to the top of the lighting lamp. Manually pushing the lighting lamp causes the connecting frame to move. The moving frame drives the moving plate to move, which in turn drives the limiting strip to move and disengage from the limiting hole. During the movement of the moving plate, pressure is applied to the spring slide rod, which in turn generates a downward elastic force on the moving plate and moves the position of the connecting frame. The connecting frame drives the moving plate to move, which in turn drives the spring slide rod to move. The movement of the spring slide rod causes the sliding top plate to slide along the inner wall of the sliding frame, which facilitates the adjustment of the position of the lighting lamp for different lighting positions. The elastic force provided by the spring slide rod drives the moving plate to move downward, which in turn causes the limiting strip to engage with the limiting hole, thus facilitating the fixation of the limiting strip's position.

[0006] Preferably, the lighting fixture includes a lighting housing, an evaporation hole on the top of the lighting housing, an air inlet on the side of the lighting housing, a lighting component fixedly connected to the inner wall side of the lighting housing, a fan fixedly connected to the top of the inner wall of the lighting housing, an air guide pipe connected to the top of the lighting housing, an arc-shaped seat fixedly connected to the bottom center of the lighting component, the top of the lighting housing fixedly connected to the bottom of the connecting frame, and a water-absorbing cotton disposed above the lighting component. The side of the water-absorbing cotton is fixedly connected to the inner wall side of the lighting housing, the top of the water-absorbing cotton contacts the bottom of the evaporation hole, and the side of the water-absorbing cotton contacts the side of the air inlet.

[0007] Preferably, the lighting assembly includes an arc-shaped lamp tube, with a lamp post fixedly connected to the top of the inner wall of the arc-shaped lamp tube. An aerodynamic hole is provided at the top of the arc-shaped lamp tube on one side of the lamp post. The side of the arc-shaped lamp tube is fixedly connected to the side of the inner wall of the lighting housing. The top of the aerodynamic hole contacts the bottom of the absorbent cotton.

[0008] Preferably, the fan includes a motor, with a straight fan blade fixedly connected to the side of the motor's drive shaft, and an arc-shaped fan blade fixedly connected to the bottom of the straight fan blade. A sliding groove adapted to an arc-shaped lamp tube is provided on one side of the bottom of the arc-shaped fan blade. The straight fan blade extends into the air duct. The top of the motor is fixedly connected to the top of the inner wall of the air duct. When the motor is started, it drives the straight fan blade to rotate, which in turn drives the arc-shaped fan blade to rotate. The arc-shaped fan blade moves the air, causing it to pass through the air inlet and enter the interior of the lighting housing through the absorbent cotton. This facilitates air exchange within the lighting housing, reducing water vapor accumulation. When the air is circulating, the lamp post is activated. The heat generated by the lamp post is transferred through the arc-shaped lamp tube to the bottom of the absorbent cotton, heating it and evaporating the water vapor accumulated inside. This evaporates the water vapor and releases it through the evaporation holes. Simultaneously, air is guided by the arc-shaped fan blade to the side of the straight fan blade and then into the air duct for exhaust, thus facilitating air exchange between the interior and exterior of the lighting housing.

[0009] Preferably, the guide top includes an arc-shaped outer shell, a rotating column is rotatably connected to the top of the arc-shaped outer shell, a rotating seat is fixedly connected to the bottom of the rotating column, an engagement groove is provided on the top of the rotating column, a brake strip is fixedly connected to the side of the rotating column, and the arc-shaped outer shell is slidably connected to the bottom of the rotating seat through the rotating column.

[0010] Preferably, the limiting component includes a brake seat, a sliding hole at the top of the brake seat, a guide groove at one side of the bottom of the brake seat, a brake pin fixedly connected to the top side of the brake seat, a side of the brake seat fixedly connected to the inner wall side of the rotating base, and a sliding connection between the brake seat and the side of the rotating pin through the sliding hole. During installation, the rotating seat is manually rotated, which in turn rotates the rotating pin, which in turn rotates the brake bar. The brake bar moves along the top of the brake seat, thereby blocking the brake bar under the setting of the brake pin, thus limiting the movement and ensuring that the rotating pin is locked on the side of the arc-shaped shell. The rotational connection between the rotating pin and the arc-shaped shell prevents the rotating pin from falling off, thus facilitating installation. The guide groove facilitates the sliding guidance of the rotating pin, thereby facilitating installation and adjustment.

[0011] Preferably, the fixing assembly includes a lower tube, a fitting seat fixedly connected to the side of the lower tube, a fitting hole opened at the top of the fitting seat, a fitting post slidably connected to the inner wall of the fitting hole, a connecting plate fixedly connected to the bottom of the fitting post, an inner wall of an upper tube fixedly connected to the side of the connecting plate, a positioning plate fixedly connected to the top of the inner wall of the upper tube, a bottom of the lower tube fixedly connected to the top of the rotating base, and the bottom of the lower tube contacting the top of the rotating base. Rotating the rotating handle causes the rotating base to rotate, which in turn causes the lower tube to rotate, which in turn causes the fitting seat to rotate. The fitting seat and the connecting plate slide together, and with the cooperation of the fitting post and the fitting hole, the lower tube is locked after rotation and installation. It is then installed to the wall via the positioning plate. The staggered design of the positioning plate and the connecting plate facilitates the installation of the positioning plate.

[0012] This invention provides an indoor ceiling light with moisture-proof function. It has the following beneficial effects:

[0013] 1. This moisture-proof indoor ceiling light is equipped with a connecting frame and a lighting lamp. The lighting lamp moves the connecting frame, which in turn moves a movable plate. The movable plate moves a limiting strip and disengages it from the limiting hole. During the movement of the movable plate, pressure is applied to the spring slide rod, which in turn generates a downward elastic force on the movable plate, moving the position of the connecting frame. The connecting frame moves the movable plate, which in turn moves the spring slide rod. The spring slide rod then moves the sliding top plate along the inner wall of the sliding frame, facilitating the adjustment of the lighting lamp's position for different lighting locations. The elastic force provided by the spring slide rod also causes the movable plate to move downward, thereby engaging the limiting strip with the limiting hole and securing the limiting strip's position.

[0014] 2. This moisture-proof indoor ceiling light is equipped with a motor. The motor drives the straight fan blades to rotate, which in turn drives the curved fan blades to rotate. The curved fan blades move the air, which passes through the air inlet and is absorbed by the absorbent cotton before entering the interior of the lighting housing. This facilitates air exchange within the lighting housing, reducing the accumulation of water vapor. When the air is circulating, the lamp post is activated. The heat generated by the lamp post is transferred through the curved lamp tube to the bottom of the absorbent cotton, heating it and evaporating the water vapor accumulated inside. The vapor is then released through the evaporation holes. Simultaneously, air is guided by the curved fan blades to the side of the straight fan blades and then into the air duct for exhaust, thus facilitating air exchange between the inside and outside of the lighting housing.

[0015] 3. This moisture-proof indoor ceiling light features a manually rotated base during installation. The rotation of the base causes the rotating column to rotate, which in turn rotates the brake strip. The brake strip moves along the top of the base, where it is stopped by the brake column, thus limiting its movement and ensuring the rotating column is locked against the side of the curved housing. The rotating connection between the rotating column and the curved housing prevents the column from falling off, facilitating installation. A guide groove allows the rotating column to slide smoothly, further simplifying installation and adjustment.

[0016] 4. This moisture-proof indoor ceiling light is equipped with a lower tube. The bottom of the lower tube contacts the top of the rotating base. Rotating the handle rotates the rotating base, which in turn rotates the lower tube. The lower tube then rotates the fitting seat, which slides in cooperation with the connecting plate. The fitting post and fitting hole work together to lock the lower tube after rotation and installation. The light is then installed on the wall via a positioning plate. The staggered design of the positioning plate and the connecting plate facilitates the installation of the positioning plate. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] For the first embodiment, please refer to... Figures 1-2 The present invention provides a technical solution: an indoor ceiling light with moisture-proof function, comprising a rotating base 1, an adjustment component 2 fixedly connected to the side of the rotating base 1, a lighting lamp 3 fixedly connected to the bottom of the adjustment component 2, a water-absorbing cotton 4 fixedly connected to the inner wall of the lighting lamp 3, a guide top 5 fixedly connected to the bottom of the rotating base 1, a limiting component 6 adapted to the guide top 5 fixedly connected to the top of the rotating base 1 away from the center, a rotating handle 7 fixedly connected to the inner side of the rotating base 1, and a fixing component 8 fixedly connected to the top of the rotating base 1.

[0028] The rotating base 1 supports the equipment, the lighting lamp 3 provides illumination, the adjusting component 2 adjusts and locks the position of the lighting lamp 3 to stabilize the lighting at different positions, and the water-absorbing cotton 4 absorbs water vapor inside the lighting lamp 3 to avoid the water vapor affecting the lighting. The guide top 5 and the limiting component 6 work together to fix and guide the guide top 5 to prevent water vapor from accumulating. At the same time, the rotating handle 7 drives the rotating base 1 to rotate, thereby driving the rotating base 1 to cooperate with the fixing component 8, which facilitates installation and adjustment. The fixing component 8 is used for quick installation and removal of the ceiling light, which facilitates quick installation and other operations.

[0029] The adjustment assembly 2 includes a sliding frame 201. A limiting hole 202 is provided at the bottom of the inner wall of the sliding frame 201. A sliding top plate 203 is slidably connected to the top of the inner wall of the sliding frame 201. The fixed end of a spring slide rod 204 is fixedly connected to the bottom of the sliding top plate 203. A movable plate 205 is sleeved and slidably connected to the movable end of the spring slide rod 204. A limiting strip 206 that matches the limiting hole 202 is fixedly connected to the bottom of the movable plate 205. A connecting frame 207 is fixedly connected to the bottom of the movable plate 205. The side of the sliding frame 201 is fixedly connected to the side of the rotating base 1. The bottom of the connecting frame 207 is fixedly connected to the top of the lighting lamp 3.

[0030] Manually push the lighting lamp 3, which moves the connecting frame 207. The moving connecting frame 207 moves the moving plate 205, which in turn moves the limiting strip 206, disengaging it from the limiting hole 202. During the movement of the moving plate 205, pressure is applied to the spring slide rod 204, causing the spring slide rod 204 to exert a downward elastic force on the moving plate 205 and move the position of the connecting frame 207. The connecting frame 207 moves the moving plate 205, which in turn moves the spring slide rod 204. The moving spring slide rod 204 causes the sliding top plate 203 to slide along the inner wall of the sliding frame 201, thus facilitating the adjustment of the position of the lighting lamp 3 for different lighting positions. The elastic force provided by the spring slide rod 204 also causes the moving plate 205 to move downward, thereby causing the limiting strip 206 to engage with the limiting hole 202, thus facilitating the fixation of the position of the limiting strip 206.

[0031] For the second embodiment, please refer to... Figures 1-5Based on the first embodiment, the present invention provides a technical solution: the lighting lamp 3 includes a lighting housing 301, an evaporation hole 302 is provided on the top of the lighting housing 301, an air inlet 303 is provided on the side of the lighting housing 301, a lighting component 304 is fixedly connected to the inner wall side of the lighting housing 301, a fan 305 is fixedly connected to the top of the inner wall of the lighting housing 301, a duct 306 is connected to the top of the lighting housing 301, an arc-shaped seat 307 is fixedly connected to the bottom center of the lighting component 304, the top of the lighting housing 301 is fixedly connected to the bottom of the connecting frame 207, and a water-absorbing cotton 4 is disposed above the lighting component 304. The side of the water-absorbing cotton 4 is fixedly connected to the inner wall side of the lighting housing 301, the top of the water-absorbing cotton 4 contacts the bottom of the evaporation hole 302, and the side of the water-absorbing cotton 4 contacts the side of the air inlet 303.

[0032] The lighting assembly 304 includes an arc-shaped lamp tube 3041, a lamp post 3042 is fixedly connected to the top of the inner wall of the arc-shaped lamp tube 3041, an air hole 3043 is opened at the top of the arc-shaped lamp tube 3041 on one side of the lamp post 3042, the side of the arc-shaped lamp tube 3041 is fixedly connected to the side of the inner wall of the lighting housing 301, and the top of the air hole 3043 contacts the bottom of the absorbent cotton 4.

[0033] The fan 305 includes a motor 3051. A straight fan blade 3052 is fixedly connected to the side of the drive shaft of the motor 3051. An arc-shaped fan blade 3053 is fixedly connected to the bottom of the straight fan blade 3052. A sliding groove 3054 adapted to the arc-shaped lamp tube 3041 is opened on one side of the bottom of the arc-shaped fan blade 3053. The straight fan blade 3052 extends into the air guide pipe 306. The top of the motor 3051 is fixedly connected to the top of the inner wall of the air guide pipe 306.

[0034] The motor 3051 is started, which drives the straight fan blade 3052 to rotate. The rotation of the straight fan blade 3052 drives the arc-shaped fan blade 3053 to rotate. The arc-shaped fan blade 3053 moves the air, which passes through the air inlet 303 and enters the interior of the lighting housing 301 through the adsorption of the water-absorbing cotton 4. This achieves air exchange inside the lighting housing 301, thereby reducing the accumulation of water vapor. When the air is circulating, the lamp post 3042 is started. The heat generated by the lamp post 3042 is transferred to the bottom of the water-absorbing cotton 4 through the arc-shaped lamp tube 3041, thereby heating the water-absorbing cotton 4. This evaporates the water vapor accumulated inside the water-absorbing cotton 4 and releases it along the evaporation hole 302. At the same time, the air enters the side of the straight fan blade 3052 along the guide of the arc-shaped fan blade 3053 and enters the interior of the air guide pipe 306 for discharge, thus facilitating air exchange between the interior and exterior of the lighting housing 301.

[0035] Third embodiment, please refer to Figures 1-7Based on the second embodiment, the present invention provides a technical solution: the guide top 5 includes an arc-shaped outer shell 501, a rotating column 502 is rotatably connected to the top of the arc-shaped outer shell 501, a rotating seat 503 is fixedly connected to the bottom of the rotating column 502, an fitting groove 504 is opened on the top of the rotating column 502, a brake strip 505 is fixedly connected to the side of the rotating column 502, and the arc-shaped outer shell 501 is slidably connected to the bottom of the rotating base 1 through the rotating column 502.

[0036] The limiting component 6 includes a brake seat 601, a sliding hole 602 is provided on the top of the brake seat 601, a guide groove 603 is provided on one side of the bottom of the brake seat 601, a brake column 604 is fixedly connected to the top side of the brake seat 601, the side of the brake seat 601 is fixedly connected to the inner wall side of the rotating base 1, and the brake seat 601 is slidably connected to the side of the rotating column 502 through the sliding hole 602.

[0037] During installation, the rotating seat 503 is manually rotated. The rotation of the rotating seat 503 drives the rotating column 502 to rotate, which in turn drives the brake strip 505 to rotate. The brake strip 505 moves along the top of the brake seat 601, thereby blocking the brake strip 505 under the setting of the brake column 604, thus limiting its movement and ensuring that the rotating column 502 is locked on the side of the arc-shaped housing 501. The rotational connection between the rotating column 502 and the arc-shaped housing 501 prevents the rotating column 502 from falling off, thus facilitating installation. The guide groove 603 facilitates the sliding guidance of the rotating column 502, thereby facilitating installation and adjustment.

[0038] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 Based on the third embodiment, the present invention provides a technical solution: the fixing component 8 includes a lower tube 801, a fitting seat 802 is fixedly connected to the side of the lower tube 801, a fitting hole 803 is opened on the top of the fitting seat 802, a fitting post 804 is slidably connected to the inner wall of the fitting hole 803, a connecting plate 805 is fixedly connected to the bottom of the fitting post 804, the inner wall of the upper tube 806 is fixedly connected to the side of the connecting plate 805, a positioning plate 807 is fixedly connected to the top of the inner wall of the upper tube 806, and the bottom of the lower tube 801 is fixedly connected to the top of the rotating base 1.

[0039] The bottom of the lower tube 801 contacts the top of the rotating base 1. Rotating the rotating handle 7 causes the rotating base 1 to rotate, which in turn causes the lower tube 801 to rotate. The lower tube 801 then causes the fitting seat 802 to rotate. The fitting seat 802 slides in cooperation with the connecting plate 805. With the cooperation of the fitting post 804 and the fitting hole 803, the lower tube 801 is locked after rotation and installation. It is then installed on the wall via the positioning plate 807. The staggered design of the positioning plate 807 and the connecting plate 805 facilitates the installation of the positioning plate 807.

[0040] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
