[0002] With the rapid development of LED lighting technology, downlights, as a common lighting fixture, are widely used in homes, commercial spaces, and offices due to their advantages such as aesthetics, energy efficiency, and ease of installation. However, the lenses of existing recessed downlights are mostly fixed with screws or one-time snap-fit structures. Replacing the lens requires disassembling the entire fixture or performing destructive operations, which is inefficient and costly. Utility Model Content
[0003] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes an embedded emergency downlight.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] An embedded emergency downlight includes a cylindrical body with a lower opening and a lens detachably connected to the opening end of the cylindrical body. The cylindrical body has an L-shaped flange extending circumferentially on the outer side near its opening end, and an annular cavity is formed between the L-shaped flange and the cylindrical body. Several notches are evenly distributed along the circumference of the L-shaped flange, and each notch is provided with an elastic buckle strip that can elastically deform relative to it. The end of the elastic buckle strip is located in the annular cavity and has a limiting flange. The lower end of the limiting flange has a third guide slope. The lens has a first protrusion extending into the annular cavity along the circumference, and a groove that can engage with the limiting flange is provided on one side of the first protrusion.
[0006] The L-shaped flange has a through hole on one side that communicates with the annular cavity. A movable ring is arranged vertically inside the annular cavity. Several pressing members that can extend and retract in the direction of the elastic buckle are evenly distributed around the movable ring. A transmission structure is provided between the first protrusion and the pressing members, which can drive the pressing members to move and press against the elastic buckle when they move closer to each other.
[0007] In one embodiment, the transmission structure includes a second protrusion disposed circumferentially on the upper end of the first protrusion. The upper end of the second protrusion has a first guide slope on one side. A plurality of transverse guide holes are evenly distributed along the circumference on the outer side of the movable ring. A movable groove is disposed below the transverse guide holes. The pressing member is L-shaped. The pressing member is correspondingly and movably inserted into the transverse guide holes and located in the movable groove. The lower end of the pressing member is provided with a second guide slope that can abut against the first guide slope parallel to it. When the pressing member is pressed against the second protrusion, the first guide slope and the second guide slope guide the pressing member to move along the transverse guide holes and press against the elastic buckle strip.
[0008] In one embodiment, a guide flange is provided on one side of the annular cavity, and the first protrusion and the movable ring are respectively recessed in the vertical direction with a first guide groove and a second guide groove that cooperate with the guide flange.
[0009] In one embodiment, the perforations are of a plurality of types, and the plurality of perforations are configured to correspond one-to-one with the positions of a plurality of elastic buckle strips.
[0010] In one embodiment, the upper side of the first protrusion has a groove recessed along the circumference, and the edge of the open end of the cylinder can be inserted into the groove.
[0011] In one embodiment, a sealing ring is embedded in the groove.
[0012] In one embodiment, an LED light panel is detachably connected to the lens via screws.
[0013] In one embodiment, the L-shaped flange end is provided with a flange along the circumference, and a decorative shell is fitted on the flange.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention achieves rapid lens installation and removal through the elastic deformation of the elastic buckle and the snap-fit design of the limiting flange, allowing operation without tools. Simultaneously, the annular cavity formed by the L-shaped flange provides a stable limiting space, ensuring the vibration resistance and sealing of the structure after lens snap-fit. Furthermore, the cooperation of the first and second guide slopes automatically triggers the release of the elastic buckle when the lens and the top pressure component are relatively close, simplifying the disassembly process and avoiding the tedious manual operation required by traditional buckles. Through the coordinated design of the elastic buckle and the transmission structure, the mechanical transmission principle (guide slope driving the top pressure component) is combined with the elastic deformation structure, achieving user-friendly rapid installation and removal while ensuring sealing, meeting the needs of intelligent lighting equipment for efficient maintenance and long lifespan.

[0020] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0021] like Figures 1-4 An embedded emergency downlight is shown, comprising a cylindrical body 1 with a lower opening, and a lens 2 detachably connected to the opening end of the cylindrical body 1. An L-shaped flange 3 extends circumferentially from the outer side of the cylindrical body 1 near its opening end, forming an annular cavity 4 between the L-shaped flange 3 and the cylindrical body 1. Several notches 5 are evenly distributed along the circumference of the L-shaped flange 3, and each notch 5 is provided with an elastic locking strip 6 capable of elastic deformation relative to it. The end of the elastic locking strip 6 is located within the annular cavity 4 and has a limiting protrusion. The limiting flange 7 has a third guide slope 8 at its lower end. The lens 2 has a first protrusion 9 along its circumference that can extend into the annular cavity 4. A slot 10 is provided on one side of the first protrusion 9 that can engage with the limiting flange 7. Specifically, the lens can be quickly installed and removed by means of the elastic deformation of the elastic buckle and the engagement design of the limiting flange, which can be operated without tools. At the same time, the annular cavity formed by the L-shaped flange provides a stable limiting space, ensuring the vibration resistance and sealing of the structure after the lens is engaged.
[0022] The L-shaped flange 3 has a through hole 11 on one side that communicates with the annular cavity 4. A movable ring 12 is vertically movable within the annular cavity 4. The movable ring 12 has several pressing members 13 evenly distributed around its circumference, capable of telescopic movement towards the elastic locking strip 6. A transmission structure is provided between the first protrusion 9 and the pressing members 13, allowing the pressing members 13 to move closer together and press against the elastic locking strip 6. Specifically, when the lens needs to be disassembled, the user simply inserts an external tool into the annular cavity through the through hole and applies force against the movable ring. This causes the pressing members on the movable ring to move closer together with the first protrusion, thereby driving the pressing members to move and press against the elastic locking strip through the transmission structure. This achieves elastic deformation of the elastic locking strip, causing the limiting flange on the elastic locking strip to disengage from the lens slot, thus completing the lens disassembly.
[0023] Furthermore, the transmission structure includes a second protrusion 14 arranged circumferentially on the upper end of the first protrusion 9. The upper end of the second protrusion 14 has a first guide slope 15. The outer side of the movable ring 12 is evenly distributed with a plurality of transverse guide holes 16. The lower side of the transverse guide holes 16 is provided with a movable groove 17. The pressing member 13 is L-shaped. The pressing member 13 is correspondingly and movably inserted into the transverse guide holes 16 and located in the movable groove 17. The lower end of the pressing member 13 is provided with a second guide slope 18 that can abut against the first guide slope 15 in parallel with the movable groove 17. When the pressing member 13 is pressed against the second protrusion 14, the first guide slope 15 and the second guide slope 18 guide the pressing member 13 to move along the transverse guide holes 16 and press against the elastic buckle strip 6.
[0024] Specifically, the guide hole and the limiting of the movable groove allow the top pressing component to move back and forth relative to the movable ring towards the elastic buckle. When the movable ring is displaced towards the first protrusion, the second guide slope of the top pressing component presses against the first guide slope of the second protrusion. Through the guiding cooperation of the first and second guide slopes, the release of the elastic buckle is automatically triggered when the lens and the top pressing component are relatively close. The up and down movement of the movable ring is synchronously controlled by the top pressing component to control the deformation of all elastic buckles, avoiding buckle damage caused by uneven force at a single point, improving durability, simplifying disassembly steps, and avoiding the tediousness of manual operation of traditional buckles.
[0025] Furthermore, a guide flange (not shown in the figure) is provided on one side of the annular cavity 4. The first protrusion 9 and the movable ring 12 each have a first guide groove 19 and a second guide groove 20 recessed vertically on one side, respectively, which cooperate with the guide flange (not shown in the figure). Specifically, the guide flange cooperates with the first guide groove and the second guide groove to ensure the correct alignment of the lens and the movable ring, avoiding misalignment during installation. That is, the slots and elastic buckles are aligned one-to-one with the top pressure component.
[0026] Furthermore, there are several perforations 11, and the positions of the several perforations 11 correspond one-to-one with the positions of the several elastic buckle strips 6.
[0027] Furthermore, a groove 21 is recessed along the circumference of the upper side of the first protrusion 9, and the edge of the open end of the cylinder 1 can be inserted into the groove 21. Furthermore, a sealing ring 22 is embedded in the groove 21. Thus, the groove and sealing ring on the first protrusion of the lens effectively prevent dust and moisture from entering the cylinder, improving waterproof and dustproof capabilities, and making it suitable for humid or high-cleanliness environments (such as bathrooms and laboratories).
[0028] Furthermore, an LED light panel 23 is detachably connected to the lens 2 via screws. This allows for independent replacement of the light source module, extending the overall lifespan of the luminaire and reducing maintenance costs.
[0029] Furthermore, the L-shaped flange 3 has a flange 24 along its circumference at its end, and a decorative shell 25 is fitted onto the flange 24. Thus, the flange at the end of the L-shaped flange, together with the decorative shell, conceals the internal mechanical structure, enhances the aesthetic appearance of the lamp, and protects the snap-fit structure from external impacts.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
