Description

Technical Field

[0001] This utility model relates to the field of downlight technology, specifically a waterproof ceiling downlight. Background Technology

[0002] Recessed ceiling lights, as a type of recessed lighting fixture, are widely used in interior lighting scenarios of various buildings such as homes, shopping malls, hotels, and offices because they remain flush with the ceiling surface after installation, have a high aesthetic appeal, and provide soft lighting effects. With the development of lighting technology, LED light sources have become the mainstream light source choice for recessed ceiling lights due to their advantages such as low energy consumption, long lifespan, and high luminous efficacy.

[0003] However, in actual use, the waterproof performance of ceiling downlights remains a key factor affecting their reliability and lifespan. Especially in humid environments such as kitchens, bathrooms, and shower rooms, or places where water droplets or moisture may be present, traditional ceiling downlights often experience the following problems due to insufficient waterproofing design:

[0004] Traditional ceiling downlights often feature a modular, spliced ​​housing with poor sealing at the seams. Moisture can easily seep into the fixture, causing short circuits in LED chips and circuit components, and in severe cases, burning out the entire light fixture and significantly shortening its lifespan. While some fixtures incorporate simple sealing measures (such as a single sealing ring), these seals are prone to aging and failure under prolonged use or drastic changes in humidity, rendering them ineffective at preventing moisture intrusion. Furthermore, the lack of multiple layers of protection at the connection between the light-transmitting panel and the housing can also easily become a point of leakage. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof ceiling downlight to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof ceiling downlight, comprising an integrated housing and a mounting clip. Heat dissipation fins are evenly distributed on the outer side of the integrated housing. A support ring is provided at the opening of the integrated housing. Two water-blocking rings are arranged on the outer wall of the support ring from the inside out. A protective cover is provided on the outer side of the support ring. A light-transmitting lens is provided at the center of the protective cover. An outer encapsulation groove and an inner encapsulation groove are respectively provided on the inner wall of the protective cover at positions corresponding to the two water-blocking rings. Sealing gaskets are provided inside both the outer and inner encapsulation grooves. Reinforcing screws are evenly distributed on the back of the support ring. The top of each reinforcing screw penetrates the support ring and connects to threaded holes evenly distributed on the protective cover between the outer and inner encapsulation grooves.

[0007] Both sides of the integrated housing are provided with mounting clips, and the top of the interior of the integrated housing is provided with a support base through a positioning ring. An LED bead is provided on one side of the support base, and a reflector bowl is also provided inside the integrated housing outside the LED bead.

[0008] Preferably, the top of the inner side of the integrated housing is provided with an inner groove for accommodating the positioning ring. The inner groove is provided with a protective gasket, and the edge of the inner groove is provided with snap-fit ​​grooves, each of which is provided with a screw hole.

[0009] Preferably, bait block one and bait block two are evenly arranged at the edge positions of the positioning ring and the side wall of the support base, respectively. Bait block one, bait block two and the snap-fit ​​groove correspond one to one, and a connecting hole for the positioning screw to pass through is provided in the middle of bait block one and bait block two. The positioning screw matches the screw hole.

[0010] Preferably, the reflector bowl is provided with docking blocks evenly on the side facing the support base, and the support base sidewall is provided with a card interface at the position corresponding to the docking blocks.

The positioning screws and screw holes match each other.

[0047] The overall structure of the integrated housing 1 is cylindrical, with an inner groove 6 at the top of its inner side for accommodating the positioning ring 7. A protective gasket 18 is provided inside the inner groove 6. The main function of the protective gasket 18 is to protect the positioning ring 7 and its related components from wear or damage during installation and use.

[0048] Four snap-fit ​​slots 3 are evenly arranged at the edge of the inner tank 6, and each snap-fit ​​slot 3 has a screw hole inside. The design of the snap-fit ​​slots 3 allows them to precisely mate with the positioning ring 7 and the bait block 8 and bait block 10 on the support base 11, thereby achieving a stable connection between the components.

[0049] Bait blocks 1 (8) and 2 (10) are evenly distributed at the sidewall edges of the positioning ring 7 and the support base 11, respectively. The number of bait blocks 1 (8) and 2 (10) is the same as the number of locking slots 3, and their positions correspond one-to-one. Each bait block 1 (8) and bait block 2 (10) has a connecting hole 17 in the middle for the positioning screw to pass through.

[0050] The positioning screw mates with the screw hole through the connecting hole 17, thereby firmly fixing the positioning ring 7 and the support base 11 to the inner groove 6. The positioning screw is designed to ensure that it can be easily screwed into the screw hole during installation and to provide sufficient tightening force after tightening.

[0051] The mounting clip 5 includes a fixing plate 28 connected to the outer wall of the integral housing 1 by fixing screws 27, and a movable clamping plate 25 is movably mounted on one end of the fixing plate 28 via a rotating shaft 30. The top end of the movable clamping plate 25 is provided with a barb 26.

[0052] A torsion spring 29 is provided between the fixed plate 28 on the outer side of the rotating shaft 30 and the movable clamping plate 25.

[0053] Fixing plate 28: The fixing plate 28 is tightly connected to the outer wall of the integrated housing 1 by fixing screws 27.

A barb 26 is provided at the top of the movable clamping plate 25; the barb 26 is designed to securely hook the object to be installed, preventing it from sliding or falling off. The movable clamping plate 25 is also made of high-strength metal to ensure its durability and reliability.

[0055] Rotating shaft 30: The rotating shaft 30 passes through the fixed plate 28 and the movable clamping plate 25, realizing the movable connection between the two. The rotating shaft 30 is made of high-hardness metal with a smooth surface to ensure that the movable clamping plate 25 can rotate smoothly.

[0056] Torsion spring 29: Torsion spring 29 is disposed between the fixed plate 28 and the movable clamping plate 25 on the outside of the rotating shaft 30. The function of torsion spring 29 is to provide restoring force, so that the movable clamping plate 25 can automatically return to its initial position when no external force is applied. Torsion spring 29 is made of a highly elastic metal, which has good elasticity and durability.

[0057] Fixing screw 27: Fixing screw 27 is used to securely connect the fixing plate 28 to the outer wall of the one-piece housing 1. The fixing screw 27 is made of high-strength metal, and its threaded design allows it to fit tightly against the fixing plate 28 and the housing 1, preventing loosening.

[0058] In use of this embodiment of the waterproof ceiling downlight, the internal components are first assembled: the protective pad 18 is placed into the inner groove 6 at the top of the inner side of the integrated housing 1, then the positioning ring 7 is placed into the inner groove 6, so that the first bait block 8 on the positioning ring 7 corresponds one-to-one with the snap-fit ​​groove 3 on the edge of the inner groove 6, then the support base 11 is placed on the positioning ring 7, ensuring that the second bait block 10 on the support base 11 also corresponds to the snap-fit ​​groove 3, and then the positioning screw is passed through the connecting hole 17 of the first bait block 8 and the second bait block 10, and screwed into the screw hole in the snap-fit ​​groove 3 to complete the fixing of the positioning ring 7 and the support base 11.

[0059] Next, the LED beads 16 are installed on one side of the support base 11 by welding or snap-fit. Then, the reflector bowl 13 is oriented towards the support base 11 so that the docking block 12 on the reflector bowl 13 is precisely docked with the snap-fit ​​interface 9 on the side wall of the support base 11, thereby fixing the reflector bowl 13.

[0060] Next, install the protective cover 14: Place the sealing gasket 22 into the outer encapsulation groove 21 and the inner encapsulation groove 24 on the inner wall of the protective cover 14, then align the protective cover 14 with the support ring 4, so that the two water-blocking rings 20 on the outer wall of the support ring 4 are embedded into the outer encapsulation groove 21 and the inner encapsulation groove 24 respectively. Finally, use the reinforcing screw 19 to pass through the support ring 4 and connect and fix it with the threaded hole 23 on the protective cover 14.

[0061] Finally, install the light fixture: Unfold the movable clamp 25 of the mounting clip 5 by rotating it via the rotating shaft 30. Insert the integrated housing 1 along with the mounting clip 5 into the mounting hole in the ceiling. Release the movable clamp 25; under the action of the torsion spring 29, the movable clamp 25 rotates inward via the rotating shaft 30. The barb 26, in conjunction with the support ring 4, clamps the edge of the mounting hole, completing the installation and fixing of the entire light fixture. During use, the LED beads 16 emit light, which is reflected by the reflector bowl 13 and then emitted through the light-transmitting lens 15. The heat dissipation fins 2 dissipate heat from the light fixture, and the multiple waterproof structures prevent water intrusion.
