[0002] Ceiling lamps all use LED light sources for illumination. In order to ensure sufficient brightness and uniform light, the LED light sources are arranged in the middle of the chassis of the ceiling lamp. Since light has the characteristic of diffusion, in order to save costs, the LED light source will no longer be arranged in the middle of a larger ceiling lamp. There are two arrangements of LED light source boards for existing ceiling lamps. One structure is that the light source board is designed to be rectangular, and the light source boards are electrically connected by welding power lines. The light source board of this structure has a low cost, but since the power line needs to be welded, the assembly steps are complicated and the assembly time is too long, resulting in increased costs. In addition, the driving voltage of the LED light source is low, and the wire diameter of the power line is small, so welding is difficult, and the light source is easy to fall off or even disconnect, causing the lamp to be easily damaged. The other structure is that the entire light source board is formed into a rectangle or circle by stamping or wire cutting. This structure does not require welding wires, has good integrity, is not easy to damage, and has simple assembly steps, but the board loss of the light source board is extremely large, there are a lot of waste boards, and the shape is fixed, which makes the product extremely expensive. In addition, the shape of the light source board is fixed and cannot be modified, resulting in too single adaptability. Utility Model Content

The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0038] The technical solution of the embodiment of the present application is briefly described below:

[0039] Embodiment 1

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, the present application provides a variable light source board, including: an irradiation board 1, arranged horizontally, the number of which is two or more, and the LED light source 2 is evenly arranged on the irradiation board 1; a connecting portion 3, arranged at the edge of the irradiation board 1, the irradiation boards 1 are connected to each other through the connecting portion 3, the connecting portion 3 protrudes upward and is higher than the surface of the irradiation board 1; a circuit 4, arranged on the irradiation board 1 and the connecting portion 3, and the LED light source 2 is electrically connected to the circuit 4. A connecting portion 3 is provided between the irradiation boards 1, and by bending the connecting portion 3, the user can bend the irradiation board 1 to the desired position or bend the light source board into the desired shape according to the use requirements, and the circuit 4 is also bent along with the connecting portion 3 to supply power to the LED light source 2 on the circuit 4. The irradiation boards 1 can be electrically connected without using welding power lines, and the bending angle can be freely adjusted, which greatly speeds up the product assembly progress, has a simple structure, high adaptability, and low cost.

[0041] The connecting portion 3 is provided with a first bending portion 31 on the connecting portion 3 and bent toward the irradiation board 1. The first bending portion 31 is used to control the bending angle of the irradiation board 1 so that the irradiation board 1 can be bent to a desired position or the light source board can be bent into a desired shape according to the use requirements of the user. The connecting portion 3 includes a second bending portion 32 which is provided at the edge of the irradiation board 1 and bent upward. The second bending portion 32 connects the edge of the irradiation board 1 and the first bending portion 31; the second bending portion 32 can ensure that the irradiation board 1 is arranged horizontally and is connected to the first bending portion 31. The first bending portion 31 and the second bending portion 32 can greatly reduce the bending angle of the connecting portion 3 to avoid the connection portion 3 bending angle being too large to cause the circuit 4 to break, thereby damaging the product. It should be noted that: the first curved portion 31 and the second curved portion 32 can make the connecting portion 3 bulge upward and be higher than the surface of the irradiation plate 1, but the connecting portion 3 is not limited to bulging upward. When the connecting portion 3 bulges downward, it is only necessary to provide a groove on the bottom shell of the lamp to place the connecting portion 3, which can also achieve the same effect. Therefore, the connecting portion 3 bulges downward and is lower than the surface of the irradiation plate 1, which should also be within the protection scope of the present utility model.

[0042] The connecting portion 3 includes a first notch 33, which is arranged on the first bending portion 31. The opening direction of the first notch 33 is upward, and the openings are close to each other inwardly. The width of the opening position of the first notch 33 is smaller than the width of the tail end position of the first notch 33. The first notch 33 can help the first bending portion 31 to bend, and can ensure that the plate will not be over-stretched and cracked when the first bending portion 31 is bent. The inward opening position of the first notch 33 can limit the bending angle of the first bending portion 31, thereby preventing the first bending portion 31 from being damaged due to excessive inward bending.

[0043] The connecting portion 3 includes a second notch 34, the opening direction of the first notch 33 and the opening direction of the second notch 34 are opposite, the connecting portion 3 includes a third notch 35, the second notch 34 is arranged at one end of the second curved portion 32 close to the first curved portion 31, and the third notch 35 is arranged at one end of the second curved portion 32 close to the irradiation plate 1; the irradiation plate 1 is bent around the connecting portion 3 to form a light source plate, the opening positions of the first notch 33 and the third notch 35 are facing the inner side of the light source plate, and the opening of the second notch 34 is facing the outer side of the light source plate. The second notch 34 and the third notch 35 can help the second curved portion 32 to bend, and can ensure that the plate will not be overstretched and cracked when the second curved portion 32 is bent.

[0044] It should be noted that due to factors such as the material, the required position of the irradiation plate or the required shape of the light source plate, the different bending angles of the connecting part will cause the bending position of the first bending part and the bending position of the second bending part to be different depending on the actual usage. However, the purpose to be achieved is the same and should also be within the scope of protection of the present utility model.

[0045] The circuit 4 includes a connecting part circuit, which is arranged according to the shape of the connecting part 3. Since the connecting part 3 is provided with a first notch 33, a second notch 34 and a third notch 35, the connecting part 3 circuit is arranged in an "S" shape according to the shapes of the first notch 33, the second notch 34 and the third notch 35.

[0046] The number of the illumination plates 1 is equal to the number of the connection parts 3 plus one, and the parts of the illumination plates 1 without the connection parts 3 are close to each other. This structure can ensure that the light on the light source board will not be lost and is more uniform.

[0047] Embodiment 2

[0048] like Figure 1 , Figure 4As shown, the present application provides a variable light source board, including: an irradiation board 1, arranged horizontally, the number of which is two or more, and the LED light source 2 is evenly arranged on the irradiation board 1; a connecting portion 3, arranged at the edge of the irradiation board 1, the irradiation boards 1 are connected to each other through the connecting portion 3, the connecting portion 3 protrudes upward and is higher than the surface of the irradiation board 1; a circuit 4, arranged on the irradiation board 1 and the connecting portion 3, and the LED light source 2 is electrically connected to the circuit 4. A connecting portion 3 is provided between the irradiation boards 1, and by bending the connecting portion 3, the user can bend the irradiation board 1 to the desired position or bend the light source board into the desired shape according to the use requirements, and the circuit 4 is also bent along with the connecting portion 3 to supply power to the LED light source 2 on the circuit 4. The irradiation boards 1 can be electrically connected without using welding power lines, and the bending angle can be freely adjusted, which greatly speeds up the product assembly progress, has a simple structure, high adaptability, and low cost.

[0049] The connecting portion 3 is provided with a first bending portion 31 on the connecting portion 3 and bent toward the irradiation board 1. The first bending portion 31 is used to control the bending angle of the irradiation board 1 so that the irradiation board 1 can be bent to a desired position or the light source board can be bent into a desired shape according to the use requirements of the user. The connecting portion 3 includes a second bending portion 32 which is provided at the edge of the irradiation board 1 and bent upward. The second bending portion 32 connects the edge of the irradiation board 1 and the first bending portion 31; the second bending portion 32 can ensure that the irradiation board 1 is arranged horizontally and is connected to the first bending portion 31. The first bending portion 31 and the second bending portion 32 can greatly reduce the bending angle of the connecting portion 3 to avoid the connection portion 3 bending angle being too large to cause the circuit 4 to break, thereby damaging the product. It should be noted that: the first curved portion 31 and the second curved portion 32 can make the connecting portion 3 bulge upward and be higher than the surface of the irradiation plate 1, but the connecting portion 3 is not limited to bulging upward. When the connecting portion 3 bulges downward, it is only necessary to provide a groove on the bottom shell of the lamp to place the connecting portion 3, which can also achieve the same effect. Therefore, the connecting portion 3 bulges downward and is lower than the surface of the irradiation plate 1, which should also be within the protection scope of the present utility model.

[0050] The connecting portion 3 includes a first notch 33 and a second notch 34. The first notch 33 is arranged on the first bending portion 31. The opening of the first notch 33 faces downward and expands outward. The width of the opening position of the first notch 33 is greater than the width of the tail end position of the first notch 33. The first notch 33 can help the first bending portion 31 to bend, and can ensure that the first bending portion 31 will not cause excessive stretching of the plate to cause cracking when bending, thereby causing damage to the product.

[0051] The connecting portion includes a second notch 34, and the second bending portion 32 is arranged between the first notch 33 and the second notch 34. The opening direction of the first notch 33 and the opening direction of the second notch 34 are opposite to each other. The first notch 33 and the second notch 34 can help the second bending portion 32 to bend, and can ensure that the second bending portion 32 will not cause excessive stretching and cracking of the plate when bending.

[0052] The circuit 4 includes a connection circuit, which is arranged according to the shape of the connection part. Since the connection part is provided with a first notch 33 and a second notch 34 , the connection circuit is arranged in an “S” shape according to the first notch 33 and the second notch 34 .

[0053] The number of the illumination plates 1 is equal to the number of the connection parts 3 plus one, and the parts of the illumination plates 1 without the connection parts 3 are close to each other. This structure can ensure that the light on the light source board will not be lost and is more uniform.

[0054] In order to realize and improve the manufacturing efficiency of the variable light source panel, an unfolded panel structure of the variable light source panel is also proposed:

[0055] like Figure 1 , Figure 2 , Figure 5 As shown, an unfolded plate structure of a variable light source plate comprises: an irradiation plate 1, the number of which is two or more, and LED light sources 2 are evenly arranged on the irradiation plates 1; a connecting portion 3, arranged between the irradiation plates 1, and the connecting portion 3 comprises a first notch 33 and a second notch 34, and the opening direction of the first notch 33 and the opening direction of the second notch 45 are opposite to each other; a circuit 4, arranged on the irradiation plate 1 and the connecting portion 3, and the LED light source 2 is electrically connected to the circuit 4; the circuit 4 comprises a connecting portion circuit, and the connecting portion circuit is arranged according to the shape of the connecting portion 3, and the connecting portion 3 circuit is arranged in an "S" shape; the irradiation plate 1 and the connecting portion 3 are formed by stamping or wire cutting, and are in a strip shape.

[0056] The unfolded plate of the light source board is formed into a strip by stamping or wire cutting. The production is simple, the wiring is easy, and there is very little waste. The cost is extremely low, which can save product costs. In addition to being able to set the irradiation plate 1 at the desired position or bend the light source board into the desired shape for use in ceiling lamps by bending the connecting portion 3, it can also be directly used in lamps such as lamp tubes that require the use of strip-shaped light source boards. It has strong applicability and manufacturers can stock large quantities of it. In addition, light source boards of this shape can save a lot of space and are easier to store, which can reduce product costs.
