[0035] The following will introduce in detail the specific structure of a lamp outer frame provided by an embodiment of the present invention and the corresponding technical effects brought thereby in conjunction with the patent drawings.

[0036] Please refer to Figure 1 - Figure 2 , Figure 1 which is a schematic structural diagram of a lamp outer frame 100 provided by this embodiment, Figure 2 and Figure 1 is a partial enlarged view thereof. A lamp outer frame 100 provided by an embodiment of the present invention includes a first connecting member and a second connecting member sequentially arranged along the circumferential direction of the lamp outer frame 100. The first connecting member and the second connecting member are welded, and the outer surface of the first connecting member is flush with the outer surface of the adjacent second connecting member.

[0037] It can be understood that since the first connecting member and the second connecting member are welded, therefore, it is possible to avoid obvious splicing gaps at the connection between the first connecting member and the second connecting member, and further avoid external sundries from entering the lamp 1 through the gaps. And, since the outer surface of the first connecting member is flush with the outer surface of the adjacent second connecting member, it is possible to improve the flatness of the outer surface of the lamp outer frame 100. The flat outer surface of the lamp outer frame 100 can prevent the user from being scratched by sharp parts during use, and the flat outer surface is easier to clean and can reduce the accumulation of dust and dirt.

[0038] Optionally, the outer side surface of the first connecting member can be an arc surface or a flat surface, and the outer side member of the second connecting member can also be an arc or a flat surface.

[0039] When the number of both the first connecting member and the second connecting member is one, and the outer surface of the first connecting member and the second connecting member is an arc surface, the outer peripheral surface of the lamp outer frame formed by connecting the first connecting member and the second connecting member is a closed circular arc surface. It can be understood that when the outer side surfaces of both the first connecting member and the second connecting member are semi-circular, the outer peripheral surface of the lamp outer frame is a circumferential surface.

[0040] Of course, in some alternative embodiments, when the number of the first connecting member and the second connecting member is one, the outer side surfaces of the first connecting member and the second connecting member are not limited to semi-circular shapes, but can also be other arc surfaces, thereby forming lamp outer frames 100 of other shapes, such as a fan-shaped lamp outer frame 100.

[0041] Optionally, the number of both the first connecting member and the second connecting member is multiple. In this embodiment, multiple means two or more. It should be noted that the number of the first connecting member and the number of the second connecting member can be the same or different.

[0042] In some alternative embodiments, when the outer sides of the first connecting member and the second connecting member are both flat surfaces, and the first connecting member is the frame 110 and the second connecting member is the corner fitting 120, that is to say, when the numbers of the frame 110 and the corner fitting 120 are both three, a triangular lamp outer frame can be formed by three frames 110 and three corner fittings 120.

[0043] In this embodiment, the numbers of the frame 110 and the corner fitting 120 are both four. The four frames 110 are arranged in sequence along the circumferential direction and the four frames 110 are arranged at an included angle in sequence. The four corner fittings 120 are also arranged in sequence along the circumferential direction. Any two adjacent frames 110 are connected by a corner fitting 120. That is to say, the corner fittings 120 and the frames 110 among the four corner fittings 120 and the four frames 110 are arranged alternately. Therefore, in this embodiment, a lamp outer frame 100 with a generally rectangular frame appearance is formed by four corner fittings 120 and four frames 110.

[0044] Of course, in some other embodiments, the numbers of the corner fitting 120 and the frame 110 can also be other numbers. For example, they can also be 5, 6 or n, so as to form a lamp outer frame 100 with a generally pentagonal, hexagonal or n-sided shape, where n > 6.

[0045] Moreover, the corner fitting 120 and the frame 110 are welded, and the appearance surfaces of the corner fitting 120 and the adjacent frame 110 are flush.

[0046] It can be understood that since the corner fitting 120 and the frame 110 are welded, therefore, it is possible to avoid obvious splicing gaps at the connection between the corner fitting 120 and the frame 110, and further avoid external sundries from entering the lamp 1 through the gaps. Moreover, since the appearance surfaces of the corner fitting 120 and the adjacent frame 110 are flush, the flatness of the appearance surface of the lamp outer frame 100 can be improved. The flat appearance surface of the lamp outer frame 100 can prevent the user from being scratched by sharp parts during use, and the flat appearance surface is easier to clean and can reduce the accumulation of dust and dirt.

[0047] In order to ensure the flatness of the appearance surface at the intersection of the first connecting member and the second connecting member, the appearance surfaces at the intersection of the first connecting member and the second connecting member are formed by grinding after welding. That is to say, the appearance surface at the intersection of the corner fitting 120 and the frame 110 is formed by grinding after welding. That is, the plane at the intersection of the corner fitting 120 and the frame 110 is formed by grinding after welding, so as to ensure that the plane at the intersection of the corner fitting 120 and the frame 110 is flush with the rest of the appearance surface, and laser welding can also ensure the connection strength between the corner fitting 120 and the frame 110.

[0048] Of course, the flushness in this embodiment is not limited to the strictly defined flushness, as long as it is approximately flush.

[0049] It should be noted that in this embodiment, the four side frames 110 are grouped in pairs, and the two side frames 110 in each group are arranged opposite to each other, and the side frames 110 in each group have the same length.

[0050] In this embodiment, the corner brackets 120 and the side frames 110 are connected by laser welding. Since laser welding can achieve more precise heat control, reduce the heat affected zone, and achieve a faster welding speed, laser welding can provide better flatness and smoothness.

[0051] Of course, in some other embodiments, the corner brackets 120 and the side frames 110 can also be welded by other methods, such as arc welding, resistance welding, plasma arc welding, ultrasonic welding or electron beam welding, etc. After welding, the appearance surface of the lamp housing 100 is polished to be flush.

[0052] In order to improve the strength of the connection between the first connecting member and the second connecting member, a protective layer is provided at the intersection of the first connecting member and the second connecting member. That is to say, in this embodiment, a protective layer is provided at the intersection of the corner brackets 120 and the side frames 110, which is used to improve the anti-corrosion effect and / or chemical resistance and / or insulation of the connection between the corner brackets 120 and the side frames 110, and can also improve the aesthetics of the appearance of the connection.

[0053] For example, the appearance surface at the connection of the corner brackets 120 and the side frames 110 can be powder sprayed. The powder spraying treatment can improve the surface quality and corrosion resistance at the connection of the side frames 110 and the corner brackets 120. It can be understood that the powder spraying treatment includes pretreatment, preprocessing the polished connection to improve the adhesion of the powder coating, then evenly spraying the powder on the connection of the corner brackets 120 and the side frames 110, and then curing the powder at the connection of the corner brackets 120 and the side frames 110.

[0054] In this embodiment, the lamp housing 100 is formed by connecting four side frames 110 through four corner brackets 120, and the four side frames 110 are arranged vertically in sequence. That is, the two adjacent side frames 110 connected by a corner bracket 120 are arranged vertically.

[0055] In order to avoid stress concentration or easy scratching of users on the adjacent side walls of the appearance surface of the second connecting member, the second connecting member includes a first outer wall 126 and a second outer wall 127 arranged at an angle, and the first outer wall 126 and the second outer wall 127 are connected by an arc transition.

[0056] For details, please continue to refer to Figure 2, in this embodiment, the corner bracket 120 includes a first outer wall 126 and a second outer wall 127 arranged at an included angle. The first outer wall 126 and the second outer wall 127 are connected by an arc transition. It can be understood that, due to the arc transition connection between the first outer wall 126 and the second outer wall 127, therefore, the four corners of the lamp outer frame 100 in this embodiment are all rounded corners, which can ensure the aesthetics and at the same time avoid scratching users due to sharp corners.

[0057] It should be noted that both the first outer wall 126 and the second outer wall 127 on the corner bracket 120 are integral outer walls. That is to say, the first outer wall 126 and the second outer wall 127 are only two parts of the integral outer wall of the corner bracket 120. Specifically, in this embodiment, the lamp outer frame 100 includes a bottom plate 150 and a connecting portion arranged on the bottom plate 150. The bottom plate 150 is annular, and the connecting portion is used to connect with the back plate 200 of the lamp 1.

[0058] Specifically, in this embodiment, the connecting portion includes a first enclosing plate 160 and a second enclosing plate 170. The second enclosing plate 170 is located inside the first enclosing plate 160. That is to say, the first enclosing plate 160 is closer to the inner circle of the bottom plate 150 relative to the first enclosing plate 160. The first enclosing plate and the second enclosing plate jointly define a connecting groove 140 for connecting with a fastener.

[0059] The back plate 200 can be connected to the connecting groove 140 through a fastener 800. It can be understood that the back plate 200 is provided with an assembly hole 201 for the fastener 800 to pass through. When installing the back plate 200 of the lamp 1, the back plate 200 can be installed with the lamp outer frame 100 by passing the fastener 800 through the assembly hole 201 and then locking it into the connecting groove 140.

[0060] Of course, in some other alternative embodiments, the connecting portion may not include the first enclosing plate 160 and the second enclosing plate 170, and it may also be other structures. For example, the connecting portion may be a clamping structure for connecting with the back plate 200 of the lamp 1, or the connecting portion extends along the extending direction of the bottom plate 150 and is provided with a plurality of screw holes for connecting with the fastener 800 to connect with the back plate of the lamp 1 through the fastener 800.

[0061] It can be understood that in some embodiments, when the lamp outer frame 100 is applicable to a ceiling lamp, the first enclosing plate 160 can be connected to the outer edge of the bottom plate 150. That is to say, at this time, the appearance surface of the lamp outer frame 100 is the appearance surface of the first enclosing plate 160.

[0062] Please continue to refer to Figure 1 - Figure 2, Optionally, in this embodiment, the lamp housing 100 further includes a third enclosing plate 180. The third enclosing plate 180 is located outside the connecting portion. An installation cavity 130 for installing the driver 900 is defined between the third enclosing plate 180 and the connecting portion. That is to say, the third enclosing plate 180 is located on the side of the first enclosing plate 160 away from the second enclosing plate 170. The third enclosing plate 180 is disposed at the outer edge of the bottom plate 150. Therefore, in this embodiment, the first enclosing plate 160 is disposed on the bottom plate 150 and is located inside the bottom plate 150 relative to the third enclosing plate 180. An installation cavity 130 for installing the driver 900 is defined between the first enclosing plate 160 and the third enclosing plate 180. That is, when the lamp housing 100 in this embodiment is applied to a panel light, the driver 900 of the panel light can be placed in the installation cavity 130, thereby avoiding the external placement of the driver 900 and realizing the internal placement of the driver 900 to reduce the size of the panel light in the height direction, and further providing a thinner panel light.

[0063] To facilitate the installation of the back plate 200 of the lamp 1, an abutting platform 181 for supporting the back plate 200 is provided on the side of the third enclosing plate 180 close to the connecting portion. That is to say, an abutting platform 181 for supporting the back plate 200 is provided on the side of the third enclosing plate 180 close to the first enclosing plate 160. The abutting platform 181 is opposite to the bottom plate 150.

[0064] The height dimension of the lamp housing 100 is between 15 and 20 mm. The height dimension can be understood as the dimension in the height direction, that is, the height dimension from the appearance surface of the bottom plate 150 of the lamp housing 100 to the side of the lamp housing 100 away from the appearance surface of the bottom plate 150, so as to ensure that the lamp 1 applied to the lamp housing 100 has a thinner dimension in the height direction.

[0065] Optionally, the height dimension of the lamp housing 100 can be 15 mm, 16 mm, 17 mm, 17.5 mm, 18 mm, 18.5 mm, 19 mm, 19.5 mm or 20 mm.

[0066] It should be noted that the bottom plate 150, the first enclosing plate 160, the second enclosing plate 170 and the third enclosing plate 180 in this embodiment are all composed of four corner codes 120 and four side frames 110. Specifically, each side frame 110 is provided with a first end plate 111, and each corner code 120 is provided with a second end plate 121. When the four corner codes 120 and the four side frames 110 are connected to form the lamp housing 100, the first end plates 111 of the four side frames 110 and the second end plates 121 of the four corner codes 120 are welded together to form an integrated bottom plate 150.

[0067] Similarly, each frame 110 has a first side plate 112, and each corner fitting 120 is provided with a first plate body 122 connected to the first side plate 112. After the four corner fittings 120 are connected to the four frames 110 to form the lamp outer frame 100, the first side plates 112 of the four frames 110 and the first plate bodies 122 of the four corner fittings 120 are welded together to form an integrated first surrounding plate 160.

[0068] Similarly, each frame 110 has a first connection structure 116, and each corner fitting 120 is provided with a second connection structure 128 corresponding to the first connection structure 116. The outer surface of the second connection structure 128 is adapted to the outer surface of the first connection structure 116. Among them, connection bumps 125 are protruded at both ends of the second connection structure 128. After the four corner fittings 120 are connected to the four frames 110 to form the lamp outer frame 100, the two ends of the second connection structure 128 of any one corner fitting 120 are respectively welded to the end walls of the first connection structures 116 of the two adjacent frames 110.

[0069] In this embodiment, a second side plate 113 is provided on the outer side of the first connection structure 116 away from the first end plate 111. The second side plate 113 is opposite to the first side plate 112. A second plate body 123 is provided on the outer side of the second connection structure 128 away from the second end plate 121. The second plate body 123 is opposite to the first plate body 122. After the four corner fittings 120 are connected to the four frames 110 to form the lamp outer frame 100, the second side plates 113 of the four frames 110 and the second plate bodies 123 of the four corner fittings 120 are welded together to form an integrated second surrounding plate 170.

[0070] That is to say, the second side plate 113, the outer wall of the first connection structure 116 away from the first end plate 111 and the first side plate 112 jointly define the above-mentioned partial connection groove 140. The second plate body 123, the outer wall of the second connection structure 128 away from the second end plate 121 and the first plate body 122 jointly define the partial connection groove 140. After the four corner fittings 120 are connected to the four frames 110, a complete connection groove 140 is formed.

[0071] A third side plate 114 is provided on each first end plate 111 of each frame 110. The third side plate 114 is provided at the edge of the first end plate 111. A third plate body 124 is provided on each second end plate 121 of each corner fitting 120. The third plate body 124 is provided at the edge of the second end plate 121. After the four corner fittings 120 are connected to the four frames 110 to form the lamp outer frame 100, the third side plates 114 of the four frames 110 and the third plate bodies 124 of the four corner fittings 120 are welded together to form an integrated third surrounding plate 180.

[0072] To facilitate the positioning of the first connecting member and the second connecting member before welding, both ends of the first connecting member along its own length direction are provided with first insertion portions, and both ends of the second connecting member are respectively provided with second insertion portions that are inserted and matched with the first insertion portions.

[0073] Specifically, please refer to Figure 3 - Figure 4 , Figure 3 which is a schematic structural diagram of the frame 110 provided in this embodiment; Figure 4 which is a schematic structural diagram of the corner fitting 120 provided in this embodiment. Optionally, both ends of the frame 110 along its own length direction are provided with first insertion portions, and both ends of the corner fitting 120 are respectively provided with second insertion portions that are inserted and matched with the first insertion portions. One of the first insertion portion and the second insertion portion is an insertion cavity 115, and the other of the first insertion portion and the second insertion portion is a connection convex block 125 that is adapted to the insertion cavity 115.

[0074] Specifically, in this embodiment, both ends of the frame 110 along its own length direction are provided with insertion cavities 115, and both ends of the corner fitting 120 are respectively provided with connection convex blocks 125 that are adapted to the insertion cavities 115.

[0075] It can be understood that before welding, the two connection convex blocks 125 on the corner fitting 120 can be respectively inserted and matched with two adjacent frames 110, so as to pre-realize the positioning and installation of the corner fitting 120 and the frame 110, thereby facilitating the subsequent welding operation of the corner fitting 120 and the frame 110 and improving the assembly efficiency of the corner fitting 120 and the frame 110.

[0076] Of course, in some other embodiments, both ends of the frame 110 along its own length direction can be provided with connection convex blocks 125, and the corner fitting 120 is provided with insertion cavities 115 that are adapted to the connection convex blocks 125.

[0077] Specifically, the first connecting member includes a first end plate 111, a first side plate 112 and a first connecting structure 116 that are connected to each other. Then, the insertion cavity 115 is jointly defined by the first connecting structure 116, the first side plate 112 and the first end plate 111.

[0078] That is, in this embodiment, the frame 110 includes a first end plate 111, a first side plate 112 and a first connecting structure 116 that are connected to each other. Both ends of the first connecting structure 116 are respectively connected to the first end plate 111 and the first side plate 112. At least part of the side walls of the first connecting structure 116, the first side plate 112 and at least part of the side walls of the first end plate 111 jointly enclose and define the insertion cavity 115. The insertion cavity 115 includes a first sub-cavity 1151 and a second sub-cavity 1152 that are connected and arranged along the height direction of the first side plate 112. The width dimension of the first sub-cavity 1151 is greater than the width dimension of the second sub-cavity 1152.

[0079] It can be understood that since the width dimension of the first sub-cavity 1151 is different from that of the second sub-cavity 1152, it can be seen that the connecting bump 125 has a structure that is respectively inserted into the first sub-cavity 1151 and the second sub-cavity 1152. Specifically, the connecting bump 125 also includes a connected first bump and a second bump. The width dimension of the first bump is greater than that of the second bump. The first bump and the second bump are respectively used to be inserted into the first sub-cavity 1151 and the second sub-cavity 1152. Through the above settings, after the connecting bump 125 is inserted into the insertion cavity 115, the accuracy of the connection between the corner fitting 120 and the frame 110 can be effectively ensured, thereby ensuring the strength of the lamp outer frame 100 composed of the corner fitting 120 and the frame 110.

[0080] Optionally, the first sub-cavity 1151 is closer to the first end plate 111 relative to the second sub-cavity 1152. That is to say, the height of the first sub-cavity 1151 with a larger width dimension is lower than that of the second sub-cavity 1152 to ensure that after the connecting bump 125 is inserted into the insertion cavity 115, the bottom wall of the insertion cavity 115 has a larger area to bear the connecting bump 125. Of course, in some other embodiments, the second sub-cavity 1152 can also be closer to the first end plate 111 relative to the first sub-cavity 1151.

[0081] Of course, in some other embodiments, the shape of the insertion cavity 115 can also be other shapes. For example, the shape of the insertion cavity 115 can be a rectangular hole shape or a circular hole shape.
