Description

Technical Field

[0001] This utility model relates to the field of bulb manufacturing technology, and in particular to a lamp board, a lamp board module, and a bulb. Background Technology

[0002] In bulb design, to mitigate the thermal impact of LED chip heat on electrical components such as electrolytic capacitors, rectifier bridges, switching transistors, and control ICs, existing solutions have attempted to spatially partition the lamp board. Specifically, current technology often uses a punching process to divide the originally flat lamp board into two mutually perpendicular or nearly perpendicular parts, one part for mounting LED chips and the other for mounting electrical components. However, the inventors discovered in actual production that the punched and bent lamp board forms two mounting surfaces at an angle, while surface mount equipment can only mount components on the same horizontal plane. To mount components on two mounting surfaces with different orientations, the lamp board must be clamped or flipped after mounting on one side, which significantly reduces production efficiency.

Therefore, they should not be construed as limitations on this utility model.

[0021] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figure 1 and Figure 2This utility model provides a lamp panel, which includes a flat panel body 100. The panel body 100 includes a first panel portion 110 and a second panel portion 120 connected and disposed inside and outside. A U-shaped gap is provided between the first panel portion 110 and the second panel portion 120. The first panel portion 110 and the second panel portion 120 are respectively used for mounting electrical components 200 and lamp beads 300. The gap allows the first panel portion 110 to be pushed and bent so that it is perpendicular to the second panel portion 120.

[0023] With the above structure, since the lamp board is a flat board body 100 in its initial state, and the first board portion 110 and the second board portion 120 are coplanarly connected, the surface mount equipment can complete the component mounting operation on both board portions on the same horizontal plane. Compared with the existing punching and bending scheme, which requires two clamping and flipping to complete double-sided mounting, this scheme eliminates the intermediate clamping process and equipment waiting time, significantly improving the cycle efficiency of the mounting process. In addition, by arranging the process of mounting first and then bending, the positioning difficulties caused by mounting on non-planar substrates are avoided. In production, there is no need to configure additional multi-angle mounting fixtures or flipping mechanisms, simplifying the configuration of production line equipment, reducing the difficulty of process debugging and tooling costs, and reducing the risk of component displacement or mounting deviation caused by multiple clamping.

[0024] In this embodiment, refer to Figure 1 and Figure 2 It also includes a connecting piece 400, which includes a first piece 410, a second piece 420 and a third piece 430 connected in sequence. The first piece 410 and the third piece 430 are respectively disposed on the first plate 110 and the second plate 120. The second piece 420 has an arched structure. The first plate 110 is electrically connected to the second plate 120 through the connecting piece 400.

[0025] With the above structure, after bending, the first plate portion 110 and the second plate portion 120 are in a spatial orientation that is perpendicular or nearly perpendicular to each other. The connecting piece 400 is fixed to two mounting surfaces with different orientations via the first piece portion 410 and the third piece portion 430, and a conductive path is constructed by crossing the included angle position via the arched second piece portion 420. The arched structure of the second piece portion 420 can effectively adapt to bending deformation, protect the connection solder joint between the first plate portion 110 and the first piece portion 410, and protect the connection solder joint between the second plate portion 120 and the third piece portion 430.

[0026] In this embodiment, refer to Figure 1 and Figure 2 A through hole 130 is provided at the connection between the first plate portion 110 and the second plate portion 120. A portion of the through hole 130 is located in the first plate portion 110 and the other portion is located in the second plate portion 120.

[0027] With the above structure, in the design of the U-shaped gap, the end of the gap, namely the root of the solid connecting bridge between the first plate portion 110 and the second plate portion 120, is the area of ​​highest stress concentration during bending. The through-hole 130 structure effectively disperses the tensile and compressive strain energy generated during bending, preventing stress accumulation at a specific point, thereby significantly reducing the probability of substrate tearing at the connection point during molding and subsequent use.

[0028] This utility model also proposes a lamp board module, which includes an electrical component 200, an LED bead 300, and the aforementioned lamp board. The electrical component 200 and the LED bead 300 are respectively disposed on the first plate portion 110 and the second plate portion 120. The electrical component 200, the first plate portion 110, the connecting piece 400, the second plate portion 120, and the LED bead 300 are electrically connected in sequence.

[0029] It is understandable that the board body 100 can be configured as a rigid-flex printed circuit board, wherein the first board portion 110 and the second board portion 120 are rigid areas, and the connecting bridge portion between them is a flexible area. Alternatively, the board body 100 can also be configured as a single-layer rigid printed circuit board, with local V-cut thinning treatment at its connecting bridge portion. Both of the above methods can enable the first board portion 110 to bend 90° without breaking during pushing. The electrical component 200 and the first piece 410 are both soldered to corresponding pads on the first board portion 110, and the LED bead 300 and the third piece 430 are both soldered to corresponding pads on the second board portion 120.

[0030] In this embodiment, refer to Figure 1 and Figure 2 The LED beads 300 are configured in multiple ways, and the multiple LED beads 300 are arranged around the first plate 110. Here, "multiple" means at least three.

[0031] This utility model further proposes a bulb lamp, which includes the aforementioned lamp board module.

[0032] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
