Description

Technical Field

[0001] This utility model relates to the field of flat panel lights, and in particular to a frameless flat panel light that is assembled by deformation. Background Art

[0002] Most current panel lights use a plastic base shell paired with a plastic lampshade, then are connected and installed with screws. This method involves many steps in production, resulting in a long production time. Moreover, because the base shell, which houses the heat source substrate, is made of plastic, its strength is poor and it is susceptible to high temperatures. Therefore, current plastic base shell panel lights are mostly small sizes of 300*300 and 300*600. If a size of 600*600 were made, the increased area and the heat from the light source would inevitably cause the panel light to deform, rendering the light fixture unusable. Furthermore, this method has another drawback: because the entire lampshade is a light-transmitting component, black spots appear where the screws are installed, which is very unsightly and has low market acceptance. To address this, many lighting companies choose to add a frame around the outside of the lampshade that abuts against the bottom edge of the lampshade, using the frame to connect with the plastic base shell for screw installation. However, this causes the frame to cover part of the lampshade, thus reducing the light-transmitting area. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a flat panel lamp that is easier to assemble and can be made in larger sizes.

[0004] The technical solution adopted by this utility model to solve the problem is: a frameless flat panel lamp assembled by deformation, comprising:

[0005] The metal base is a rigid structure. The metal base includes a main base plate and an annular side plate that surrounds the outer periphery of the main base plate and is inclined outward. The main base plate and the annular side plate form a lamp cavity. A lamp body is installed in the lamp cavity. The angle between the annular side plate and the main base plate has a first state C and a second state D. The angle of the second state D is greater than that of the first state C.

[0006] The lampshade includes a main cover plate and a mounting side plate that surrounds the outer periphery of the main cover plate and extends rearward. The mounting side plate and the main cover plate are integrally formed and are light-transmitting. The inner wall of the mounting side plate is provided with a plurality of inwardly protruding locking protrusions. The locking protrusions and the rear end face of the main cover plate enclose a locking cavity that opens inward. When the angle between the annular side plate and the main base plate is in a first state C, the bottom edge of the annular side plate can movably abut against the back of the lampshade and the bottom edge of the annular side plate is located outside the locking cavity. The main base plate can drive the annular side plate to undergo rigid deformation under the action of external force, thereby deforming the angle between the annular side plate and the main base plate from the first state C to the second state D and causing the bottom edge of the annular side plate to expand outward and thus embed into the locking cavity.

[0007] As a further improvement to the above technical solution, the main base plate is square, and the main cover plate is also square.

[0008] As a further improvement to the above technical solution, the bottom of the annular side plate is provided with an outwardly inclined arc-shaped part, and the outer side of the arc-shaped part is arched.

[0009] As a further improvement to the above technical solution, when the angle between the annular side plate and the main seat plate is in the second state D, the top of the outer side of the arc-shaped part abuts against the bottom of the locking protrusion.

[0010] As a further improvement to the above technical solution, the bottom of the locking protrusion is provided with a reinforcing rib plate that connects to the inner side wall of the mounting plate.

[0011] As a further improvement to the above technical solution, in the first state C, the angle between the annular side plate and the main seat plate is between - degrees, and in the second state D, the angle between the annular side plate and the main seat plate is between - degrees.

[0012] As a further improvement to the above technical solution, the main base plate is provided with several reinforcing grooves.

[0013] As a further improvement to the above technical solution, the length and width of the lampshade are both not less than 500mm.

[0014] The beneficial effects of this utility model are as follows: Because the metal base is made of metal and has a rigid structure, the metal base includes a main base plate and an annular side plate that surrounds the main base plate and tilts outwards. During installation, the metal base is first installed onto the back of the lampshade. At this time, the angle between the annular side plate and the main base plate is in the first state C. The bottom of the annular side plate can smoothly abut against the back of the main cover plate and is located outside the locking cavity. Then, a force is applied to the main base plate towards the lampshade, thereby driving the main base plate to move downwards. Because the annular side plate tilts outwards and its bottom edge abuts against the back of the main cover plate, the downward pressing of the main base plate will cause the annular side plate to swing further outwards, thus causing the angle between the annular side plate and the main base plate to undergo rigid deformation from the first state C to the second state D. This deformation process occurs in non- The irreversible force caused the bottom edge of the annular side plate to move outward and engage in the locking cavity, thus completing the connection between the metal base and the lampshade. The entire installation process is simple and convenient, with fewer steps, which greatly reduces the labor cost of the installation process. Moreover, no additional frame is needed for installation. Since the metal base is made of metal, it is stronger and less prone to deformation. Therefore, the size of the flat panel light produced by this structure can be made larger, thus meeting the market demand for large-size flat panel lights. At the same time, the entire lampshade is integrally molded and can transmit light without the need for bolts. Therefore, the entire bottom surface of the lampshade can form a light-transmitting surface, thus achieving the maximum light transmission area and eliminating dark areas at the edges.

[0024] Reference Figures 1 to 4 A frameless flat panel light assembled by deformation, comprising:

[0025] The metal base 10 is a rigid structure. The metal base 10 includes a main base plate 11 and an annular side plate 12 that surrounds the outer periphery of the main base plate 11 and is inclined outward. The main base plate 11 and the annular side plate 12 form a lamp cavity. A lamp body is installed in the lamp cavity. The angle between the annular side plate 12 and the main base plate 11 has a first state C and a second state D. The angle of the second state D is greater than that of the first state C.

[0026] The lampshade 20 includes a main cover plate 21 and a mounting side plate 22 that surrounds the outer periphery of the main cover plate 21 and extends rearward. The mounting side plate 22 and the main cover plate 21 are integrally formed and are light-transmitting. The inner wall of the mounting side plate 22 is provided with a plurality of inwardly protruding locking protrusions 23. The locking protrusions 23 and the rear end face of the main cover plate 21 enclose to form a locking cavity 24 that opens inward. When the angle between the annular side plate 12 and the main base plate 11 is in the first state C, the bottom edge of the annular side plate 12 can movably abut against the back of the lampshade 20 and the bottom edge of the annular side plate 12 is located outside the locking cavity 24. The main base plate 11 can drive the annular side plate 12 to undergo rigid deformation under the action of external force, thereby deforming the angle between the annular side plate 12 and the main base plate 11 from the first state C to the second state D and causing the bottom edge of the annular side plate 12 to expand outward and then embed into the locking cavity 24.

[0027] Since the metal base 10 is made of metal and has a rigid structure, the metal base 10 includes a main base plate 11 and an annular side plate 12 that surrounds the outer periphery of the main base plate 11 and tilts outward. During installation, the metal base 10 is first installed on the back of the lampshade 20. At this time, the angle between the annular side plate 12 and the main base plate 11 is in the first state C. The bottom of the annular side plate 12 can smoothly abut against the back of the main cover plate 21 and is located outside the locking cavity 24. Then, a force is applied to the main base plate 11 toward the lampshade 20 to drive the main base plate 11 to move downward. Since the annular side plate 12 tilts outward and its bottom edge abuts against the back of the main cover plate 21, the downward pressing of the main base plate 11 will cause the annular side plate 12 to swing further outward, thereby causing the angle between the annular side plate 12 and the main base plate 11 to change from the first state C to the second state D, forming a rigid shape. The deformation process is irreversible without external force, causing the bottom edge of the annular side plate 12 to move outward and engage in the locking cavity 24, thus completing the connection between the metal base 10 and the lampshade 20. The entire installation process is simple and convenient, with fewer steps, which greatly reduces the labor cost of the installation process. Moreover, no additional frame is needed for installation. Since the metal base 10 is made of metal, it has higher strength and is less prone to deformation. Therefore, the size of the flat panel light produced by this structure can be made larger, thus meeting the market demand for large-size flat panel lights. At the same time, the entire lampshade 20 is integrally molded and can transmit light without the need for bolts for connection. Therefore, the bottom surface of the entire lampshade 20 can form a light-transmitting surface, thus achieving the maximum area of ​​light transmission and maximizing the light transmission area without creating dark areas at the edges.

[0028] In this design, the main base plate 11 is preferably square, and the main cover plate 21 is also square. In other embodiments, the main base plate 11 may also be circular or hexagonal, etc.

[0029] Further optimization is preferred, where the bottom of the annular side plate 12 is provided with an outwardly inclined arc-shaped portion 13. The outer side of the arc-shaped portion 13 is arched. The function of the arc-shaped portion 13 is twofold: first, to increase the inclination of the bottom edge of the annular side plate 12; and second, because the outward inclination of the arc-shaped portion 13 creates a bend, the main deformation of the annular side plate 12 is completed by the arc-shaped portion 13, thereby maintaining the stability of the main area of ​​the annular side plate 12. Further optimization is preferred, in the second state D, where the top of the outer side of the arc-shaped portion 13 abuts against the bottom of the locking protrusion 23.

[0030] To further optimize the design and maintain the strength of the locking cavity 24, it is preferable that the bottom of the locking protrusion 23 is provided with a reinforcing rib 25 that is connected to the inner wall of the mounting side plate 22.

[0031] In this solution, preferably in the first state C, the angle between the annular side plate 12 and the main seat plate 11 is between 110 and 145 degrees; and in the second state D, the angle between the annular side plate 12 and the main seat plate 11 is between 120 and 160 degrees. The angles disclosed here are the optimal angles; other angles can also achieve the same effect.

[0032] In this design, to increase the strength of the main seat plate 11, it is preferable that the main seat plate 11 is provided with several reinforcing grooves.

[0033] In this solution, it is preferred that the length and width of the lampshade 20 are not less than 500mm. Of course, in other embodiments, the lampshade 20 can also be a small-sized structure, such as 300*300mm, 400*400mm, etc.

[0034] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
