Description

Technical field

[0001] The utility model belongs to the technical field of lamps, and particularly relates to a panel lamp with adjustable angle. [Background Technology]

[0002] Panel lights are primarily used in places like office or commercial lighting. They are typically mounted on the ceiling and can be hoisted or embedded. After installation, the light emits downward, and the direction of the light cannot be adjusted. In some key areas of commercial lighting, such as wall posters, decorative paintings, and shelves, traditional panel lights are inadequate for accent lighting. To better display items on the wall or products on the shelves, the lighting fixtures need to be powered and their luminous flux increased. However, this power increase results in excessive luminous flux in the entire environment, wasting energy and creating a certain degree of light pollution. Currently, track spotlights are commonly used for accent lighting. Using track spotlights separately for accent lighting in places where panel lights are used increases the variety of lighting fixtures and is more complex to install, requiring the installation of separate tracks. [Utility Model Content]

[0008] Preferably, the angle fixing part is a bump bead, and the left and right side walls of the shell are provided with threaded bump bead fixing holes. The bump bead is provided with a bump bead body, a bump bead spring for driving the bump bead body to pop out, a stud, and a boss. The bump bead is threadedly connected to the bump bead fixing hole through the stud, and the boss is fitted with the inner wall of the shell and the bump bead body protrudes from the inner wall of the shell.

[0009] Preferably, the positioning groove includes a starting positioning groove corresponding to the starting position of the adjustment angle and an end positioning groove corresponding to the maximum position of the adjustment angle. A limiting rib is provided on the outer surface of the end cover near the end positioning groove. After the ball body is inserted into the end positioning groove, the boss cooperates with the limiting rib.

[0010] Preferably, the interval angle between two adjacent positioning grooves is 1°; and / or the angle between the last positioning groove and the starting positioning groove is 60°.

[0011] Preferably, the shell is a rectangular body with an open bottom, and the shape of the lamp body includes a straight surface and a curved surface connected to the upper end of the straight surface.

[0012] Preferably, the corners of the end cover corresponding to the bottom of the arc surface of the lamp body are provided with lugs for pulling the lamp body assembly to rotate.

[0013] Preferably, the end cover is fixed to the left and right ends of the lamp body by countersunk screws, and the left and right ends of the lamp body are provided with screw grooves connected to the countersunk screws.

[0014] The utility model adopts the above technical solution, which has the following beneficial effects:

[0015] 1. The panel light includes a housing and a lamp body assembly. The lamp body assembly includes a lamp body, a circuit board installed in the lamp body, end caps located at the left and right ends of the lamp body, and a lampshade located on the lower side of the lamp body. An angle adjustment structure is provided between the housing and the lamp body assembly. The lamp body assembly can be rotated downward according to the use requirements of the lamp to change the illumination direction of the lamp. In this way, after the panel light is installed, the illumination direction of the light-emitting surface can be adjusted according to the needs of the use scenario. Therefore, it can be used as an ordinary panel light or as a lighting fixture for key areas.

[0016] 2.

[0017] 3. The bumper is threadedly connected to the bumper fixing hole through the stud, and the boss is fitted with the inner wall of the shell, and the bumper body protrudes from the inner wall of the shell. This makes it convenient to assemble the bumper, and because the bumper body protrudes from the inner wall of the shell, the bumper is elastically snapped into the positioning groove when it corresponds to the positioning groove.

[0018] 4. Corresponding to the end positioning groove at the maximum adjustment angle position, a limiting rib is provided on the outer surface of the end cover near the end positioning groove. In this way, when the lamp body assembly is pulled down to the maximum angle, the bead body is inserted into the end positioning groove and the rear boss cooperates with the limiting rib to limit the position of the lamp body assembly and limit the maximum rotation angle of the lamp body.

[0019] 5. Since the spacing angle of the positioning grooves is 1°, when the lamp body assembly is pulled down by the spacing of one positioning groove, the lamp body assembly rotates 1°, and the angle between the last positioning groove and the starting positioning groove is 60°, so the lamp body assembly can be pulled down 60° relative to the initial angle.

[0020] 6. The outer shell is a rectangular body with an open bottom. The shape of the lamp body includes a straight surface and a curved surface connected to the upper end of the straight surface. The above design ensures that during the rotation of the lamp body assembly around the rotating axis, the curved surface is always close to the bottom end of the rear side wall of the outer shell without any large gap, which is more beautiful and practical.

[0021] 7. The shaft uses screws to facilitate assembly.

[0022] 8. The corners of the end cap corresponding to the bottom of the arc surface of the lamp body are provided with lugs for pulling the lamp body assembly to rotate. Pulling the lugs by hand drives the lamp body assembly to rotate downward, which is convenient and labor-saving.

Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0039] Those skilled in the art will appreciate that, unless there is any conflict, the features in the following embodiments and implementations may be combined with each other.

[0040] The terms used in this utility model are for the purpose of describing specific embodiments only and are not intended to limit the utility model. For example, the terms "upper," "lower," "inner," and "outer" used below to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are used only to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation.

[0043] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0044] Reference Figures 1 to 11 The figure shows an angle-adjustable panel light, comprising a housing 2, a lamp assembly 1, and a rotating shaft 24 disposed between the housing 2 and the lamp assembly 1. The lamp assembly rotates about the rotating shaft to adjust the panel light's illumination angle. The lamp assembly 1 comprises a lamp body 11, a circuit board 13 mounted within the lamp body, end caps 12 disposed at each end of the lamp body, and a lampshade 14 disposed beneath the lamp body. The rotating shaft 24 extends between the left and right side walls of the housing and the corresponding end caps. An angle adjustment mechanism is provided between the housing 2 and the lamp assembly 1 to control the lamp assembly's rotation angle and achieve positioning.

[0045] In one embodiment, the angle adjustment structure includes an angle fixing member and an angle adjustment portion, wherein the angle fixing member is disposed on the housing, and the angle adjustment portion is disposed on the end cap. Alternatively, the angle fixing member is disposed on the end cap, and the angle adjustment portion is disposed on the housing. In other words, the positions of the angle fixing member and the angle adjustment portion on the housing and the end cap are interchangeable.

[0046] Furthermore, the angle adjustment portion includes N limiting portions, where N≥2, and the limiting portions cooperate with the angle fixing member to fix the lamp body assembly at a set angle.

[0047] It can be understood that the angle fixing member and the angle adjustment part can take various forms. Preferably, the limiting part is a positioning groove or a positioning hole, and the multiple positioning grooves or positioning holes are arranged in a circular arc with the rotating shaft as the center, and after the lamp body assembly is rotated into place, the angle fixing member cooperates with the positioning groove or positioning hole corresponding to the angle to achieve positioning.

[0048] In this embodiment, the angle fixing member is a bump bead, and the bump bead 23 is provided on the left and right side walls of the shell, and the positioning groove 121 on the end cover. Several positioning grooves 121 are arranged in a circular arc with the rotating shaft 24 as the center. The lamp body assembly 1 rotates around the rotating shaft 24 to adjust the angle, and after rotating into place, the bump bead 23 is clamped into the positioning groove 121 corresponding to the angle for positioning.

[0049] As the lamp assembly rotates downward, the end cap rotates, causing the bumper to retract inward. As the end cap rotates downward, the bumper engages the second positioning groove. As the end cap rotates downward, the bumper engages one by one into the next positioning groove. This allows the panel light to be adjusted in the direction of the light-emitting surface according to the application scenario. It can be used as a standard panel light or as a lighting fixture for key areas.

[0050] Specifically, the left and right side walls of the housing 2 are provided with threaded bumper fixing holes 22. The bumper includes a bumper body 233, a bumper spring (not shown in the figure, but reference can be made to the relevant structure in the prior art) that drives the bumper body to pop out, a stud 231, and a boss 232 provided between the bumper body and the stud. The bumper is connected to the bumper fixing hole 22 via the stud 231, with the boss 232 abutting against the inner side wall of the housing and the bumper body 233 protruding from the inner side wall of the housing. This not only facilitates the assembly of the bumper, but also, because the bumper body protrudes from the inner side wall of the housing, the bumper elastically snaps into the positioning groove when it corresponds to the positioning groove.

[0051] After the lamp assembly is assembled, the entire lamp assembly is located in the housing, and the lower surface of the lamp body 11 is flush with the lower surface of the housing 2. Then, according to the use requirements of the lamp, the lamp assembly is rotated downward to change the illumination direction of the lamp. The rotation angle of the lamp assembly corresponds to the number and angle of the positioning grooves, such as Figure 5 and Figure 6 As shown, the plurality of positioning grooves 121 include a starting positioning groove 1211 corresponding to the starting position of the adjustment angle and a final positioning groove 1212 corresponding to the maximum position of the adjustment angle. The interval angle between two adjacent positioning grooves is 1°. In this embodiment, the plurality of positioning grooves 121 are arranged on an arc with a radius of 165 mm. The angle between the starting positioning groove 1211 and the horizontal plane of the end cover is 15°, and the angle between the final positioning groove 1212 and the starting positioning groove 1211 is 60°, that is, the angle of the final positioning groove 1212 is 75°. It is understandable that the angle of the starting positioning groove 1211 can also be less than 15°, and the angle of the final positioning groove 1212 can also be greater than 75°. The rotation angle of the lamp body assembly can be designed to be greater than 60° or less than 60°.

[0052] like Figure 5 、 Figure 8 and Figure 9 As shown, the outer surface of the end cap 12 is provided with a limiting rib 122 near the rear positioning groove 1212. After the ball body 233 is inserted into the rear positioning groove 1212, the boss 232 is locked in position with the limiting rib 122. Since the limiting rib restrains the ball, it also restrains the lamp body assembly, preventing the lamp body assembly from further rotating relative to the housing to adjust the angle to a large angle, thus limiting the maximum rotation angle of the lamp body assembly.

[0053] like Figure 4 As shown, the housing 2 is a rectangular body with an open bottom. The lamp body 11 comprises a straight surface 111 and a curved surface 112 connected to the upper end of the straight surface. Two rotating shafts are connected to the left and right bottom ends of the straight surface, respectively. The left and right side walls of the housing 2 are provided with rotating shaft holes for connecting to the rotating shafts. The end cap 12 is provided with threaded holes 125, which are screwed to the threaded holes, i.e., the rotating shafts are screwed to facilitate assembly. Furthermore, this design ensures that the curved surface remains close to the bottom end of the rear wall of the housing during rotation around the rotating shaft, eliminating any significant gaps, resulting in a more aesthetically pleasing and practical design.

[0054] Furthermore, the end cap 12 is provided with a lug 123 at the corner corresponding to the bottom of the arc surface of the lamp body for pulling the lamp body assembly to rotate. The lug provides a force point for rotating the lamp body assembly, and the lug is pulled up and down by hand, which is convenient and labor-saving.

[0055] Specifically, the lamp body 11 is an integral extruded aluminum profile, the housing 2 is formed by bending a sheet metal, and the mouth is provided with a flange 21. Not only is the molding quality high, but the cost is low and the appearance is beautiful.

[0056] Specifically, the end cover 12 is fixed to both ends of the length of the lamp body by countersunk screws. The two ends of the length of the lamp body are provided with screw grooves 115 connected to the countersunk screws, and the end cover is provided with countersunk holes 124. A connecting rib 113 is provided between the bottom of the curved surface and the straight surface, and the connecting rib is provided with screw holes. The circuit board 13 is reserved with mounting holes, and the positions correspond to the screw holes on the connecting rib, and are connected to the circuit board fixing screws 131. Usually, the circuit board fixing screws 131 use cross countersunk screws to facilitate screwing, and of course, they can also be changed to screws of other head shapes and slot types. A card slot 114 is provided on the inner side wall of the bottom of the curved surface and the straight surface, and the lampshade 14 is provided with a card rib that cooperates with the card slot. The lampshade is very convenient to install and remove. Referring to the prior art, the lampshade 14 is usually made of PC material, but of course it can also be changed to other light-transmitting materials.

[0057] First, assemble the lamp body. The lamp body is a one-piece extruded aluminum profile with one straight surface and one curved surface. These two surfaces are connected by connecting ribs, which are 40mm from the bottom surface. The circuit board is screwed to the upper surface of the connecting ribs inside the lamp body. After the lampshade is inserted into the slot, the end caps are installed at each end of the lamp body. The left and right end caps are mirror images of each other, and they have countersunk holes that correspond to the screw slots on the lamp body. Countersunk screws secure the end caps to the ends of the lamp body.

[0058] The lamp body, end cover, circuit board, countersunk screws, circuit board fixing screws, and lampshade are combined together to form a lamp body assembly. After assembly, the lamp body assembly is placed into the shell. When assembling the lamp body assembly, align the threaded hole 125 on the end cover with the shaft holes on the left and right sides of the shell so that the lower surface of the lamp body 11 is flush with the lower surface of the shell 2. The two shafts 24 pass through the shaft holes on both sides of the shell and lock into the threaded holes 125 of the end cover to complete the fixation of the lamp. After the shaft 24 is fully screwed into the threaded hole, due to the limitation of the profile, there is a gap of 0.4mm between the inner surface of the screw nut and the outer surface of the shell, and there is a gap of 0.5mm between the end covers on both sides of the lamp body assembly and the inner side of the shell. At this time, the bumpers on the left and right sides are stuck in the starting grooves of the end covers at both ends of the lamp body assembly, which limit the lamp body assembly and prevent the lamp from rotating under the action of gravity.

[0059] like Figure 10 and Figure 11As shown, the lamp body assembly can be rotated according to the use requirements of the lamp to change the illumination direction of the lamp. When rotating, the lugs 123 of the left and right end caps are pulled downward (outward) to rotate. During rotation, due to the spring of the bumper, as the end cap rotates downward, the bumper 23 will shrink inward. As the end cap rotates downward, the bumper is stuck into the second groove. As the end cap rotates downward, the bumper will be stuck into the groove one by one. The lamp body assembly cannot be rotated upward (inward). Since the interval angle of the grooves of the left and right end caps is 1°, pulling down one groove will rotate the lamp body assembly 1°. Since the angle between the end positioning groove 1212 and the starting positioning groove 1211 is 60°, the lamp can be pulled down 60°. When pulled down to 60°, the bumper is in the end positioning groove. At this time, the bumper boss will fit with the arc-shaped limiting rib next to the end positioning groove, thereby limiting the lamp body assembly, so that the lamp body can only rotate 60° relative to the initial angle.

[0060] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art will understand that the utility model includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the utility model are intended to be included within the scope of the claims.
