Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED downlight technology, and in particular to an LED downlight with an adjustment and protection ring mechanism. Background Technology
[0002] LED downlights, as a high-efficiency and energy-saving lighting fixture, have been widely used in various indoor lighting scenarios such as homes, businesses, and offices. In actual installation and use, in order to achieve the best lighting effect, it is often necessary to fine-tune the projection angle of the light.
[0003] However, most existing adjustable LED downlights can only achieve pitch adjustment in one direction, and cannot be rotated and fine-tuned on the horizontal plane, which limits the flexibility of the illumination coverage. If rotation adjustment on the horizontal plane is required, the entire light body needs to be removed from the ceiling, rotated, and then reinstalled, which is quite troublesome.
[0004] Therefore, we propose an LED downlight with an adjustable protection ring mechanism to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an LED downlight with an adjustable protective ring mechanism to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: An LED downlight with an adjustable protective ring mechanism includes a lamp housing, a lamp core column, and a spring clip. An adjustable ring is provided between the lamp housing and the lamp core column. A rotating shaft is symmetrically fixed on the inner ring of the adjustable ring, and a rotating sleeve is symmetrically fixed on the outer ring of the lamp core column. The rotating sleeve rotates around the rotating shaft. symmetrical screw holes are provided on the outer wall of the lamp housing, and a screw is screwed into each screw hole. A track bar is installed at the end of the screw bar near the adjustable ring. The adjustable ring is clamped between a pair of track bars and can rotate around the axis of the track bars.
[0007] In a further embodiment, the inner step of the lamp housing is symmetrically fixed with radially extending protrusions on the lower surface of the corresponding track strip, and the lower surface of the track strip is provided with a groove for the protrusions to slide into.
[0008] In a further embodiment, the track bar and the screw are rotatably connected.
[0009] In a further embodiment, the length of the screw is less than the length of the screw hole, and the outer end of the screw does not protrude beyond the outer port of the screw hole.
[0010] In a further embodiment, the adjusting ring is composed of two symmetrical semi-track rings spliced together, and both the upper and lower ends of the two semi-track rings are covered with ring covers, and the semi-track rings and ring covers are connected by several screws.
[0011] In a further embodiment, the inner ring of the semi-track ring extends outward to form an inclined guide edge, and the inner ring of the ring cover is provided with a guide groove that cooperates with the guide edge.
[0012] In a further embodiment, a friction pad is connected to the outer wall of the end of the rotating shaft near the rotating sleeve.
[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model features an adjustment ring and a track bar, allowing the entire adjustment ring and lamp core column to rotate horizontally 360° around the axis of the lamp housing. The rotating shaft and rotating sleeve allow the lamp core column to be adjusted in pitch relative to the adjustment ring. The two adjustment structures are simple and independent of each other, which not only improves the flexibility of light positioning but also eliminates the hassle of having to remove the entire lamp body from the ceiling to adjust the horizontal angle.

[0016] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 An LED downlight with an adjustable protective ring mechanism includes a lamp housing 1, a lamp core 2, and a spring clip 3. The lamp housing 1 has a cylindrical structure. The spring clip 3 is symmetrically and rotatably mounted on the outside of the lamp housing 1. The lamp core 2 is located inside the lamp housing 1, and the light-emitting LED beads are disposed in the lamp core 2. Two screw holes 11 are symmetrically opened on the outer wall of the lamp housing 1. Radially extending protrusions 12 are symmetrically fixed on the stepped edge inside the lamp housing 1.
[0020] An adjusting ring 4 is provided between the lamp housing 1 and the lamp core column 2. The adjusting ring 4 is composed of two symmetrical semi-track rings 41 spliced together. The upper and lower ends of the two semi-track rings 41 are covered with ring covers 42 and are connected and fixed into a whole by several screws 43. The key is that the outer ring of the adjusting ring 4 is machined with a ring-shaped recessed groove, and the inner ring of the semi-track ring 41 extends outward to form an inclined guide edge 44. The inner ring of the ring cover 42 is provided with a guide groove that matches it, so as to ensure that during assembly, the ring cover 42 presses the semi-track ring 41 towards the axis, ensuring that it is firmly spliced and accurately aligned. On the inner ring of the adjusting ring 4, a rotating shaft 5 is symmetrically fixed.
[0021] A rotating sleeve 21 is symmetrically fixed on the outer ring of the lamp wick column 2. During assembly, the rotating sleeve 21 rotates and fits around the rotating shaft 5, so that the lamp wick column 2 can be tilted relative to the adjusting ring 4. A friction pad 51 is connected to the outer wall of the end of the rotating shaft 5 near the rotating sleeve 21. The friction pad 51 can be made of TPU material to increase rotational damping and prevent the lamp wick column 2 from shifting on its own.
[0022] The track bar 6 is an annular bar that mates with the recessed groove on the outer ring of the adjusting ring 4. It is mounted on the protruding strip 12 of the lamp housing 1, and a groove 61 is provided on its lower surface. The groove 61 slides into the protruding strip 12 of the lamp housing 1, ensuring that the track bar 6 can only slide radially along the lamp housing 1. The adjusting ring 4 sits on a pair of track bars 6 through the annular recessed groove on its outer ring, that is, it is sandwiched between a pair of track bars 6, and can rotate freely around the axis of the track bar 6, thereby realizing the horizontal adjustment of the lamp wick column 2.
[0023] The screw 7 is screwed into the screw hole 11 of the lamp housing 1, and its inner end is rotatably connected to the track bar 6. When the screw 7 is rotated, the track bar 6 can be pushed to move radially. When a pair of track bars 6 move in opposite directions, the adjusting ring 4 can be loosened, making it easy to disassemble the adjusting ring 4. The screw 7 does not protrude from the outer port of the screw hole 11, thereby preventing accidental rotation during installation and removal.
[0024] Assembly process: Place the lamp post 2 between the two semi-track rings 41, align the rotating sleeve 21 on the lamp post 2 with the rotating shaft 5 on the semi-track ring 41, cover the upper and lower ring covers 42, and tighten the entire adjusting ring 4 with screws 43. At this time, the lamp post 2 is hinged in the adjusting ring 4 and can be tilted and rotated. Then align the groove 61 on the lower surface of the track bar 6 with the protrusion 12 inside the lamp housing 1, slide it into place, and then screw the screw 7 into the screw hole 11 and connect it to the track bar 6. Next, insert the assembled lamp wick column 2 and adjusting ring 4 assembly from the bottom of the lamp housing 1 upwards, so that the annular groove on the outer ring of the adjusting ring 4 accurately engages with the pair of track bars 6 already installed inside the lamp housing 1. At this point, the entire lamp wick column 2 assembly can rotate horizontally.
[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
