[0028] Next, in combination with the accompanying drawings and embodiments, the specific embodiments of the present utility model will be further described in detail. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0029] As Figures 1 to 3As shown in the figure, an LED lamp bead with multiple light-emitting points includes a base, a strip-shaped heating chip, a positive arc conductive sheet, a negative arc conductive sheet, a positive pin, and a negative pin. One end of the three strip-shaped heating chips converges and is close together, and is arranged in a fan shape on the base. Preferably, the base is provided with positioning grooves for positioning and installing the strip-shaped heating chips. By setting the positioning grooves, the installation stability of the strip-shaped heating chips can be enhanced, and they are not easily loosened or moved. The two ends of the strip-shaped heating chip respectively have a positive connection point and a negative connection point. The positive arc conductive sheet is arranged on the base and close to one end of the three strip-shaped heating chips, and is respectively electrically connected to the three positive connection points. The negative arc conductive sheet is arranged on the base and close to the other end of the three strip-shaped heating chips, and is respectively electrically connected to the three negative connection points. Specifically, the positive arc conductive sheet is welded to the three positive connection points respectively. The negative arc conductive sheet is welded to the three negative connection points respectively. By arranging the three light-emitting chips in this way and realizing the parallel connection of the three strip-shaped heating chips, not only the space of the base is effectively utilized, but also compared with the centralized setting of the light-emitting chips, through the fan-shaped arrangement, the uniformity and irradiation range of the light can be effectively diffused and enhanced. The two ends of each strip-shaped heating chip are respectively provided with a positive connection point and a negative connection point, which is convenient for subsequent circuit connection. The upper end of the positive pin passes through the base and is connected to the positive arc conductive sheet. The upper end of the negative pin passes through the base and is connected to the negative arc conductive sheet. Specifically, the positive pin and the negative pin are arranged oppositely, with a simple structure design and good structural symmetry. Moreover, the positive pin and the negative pin have the same shape and size. The positive pin is a square column structure, a cylindrical structure, a triangular column structure, or a square sheet structure.

[0030] The LED lamp bead with multiple light-emitting points combines the base, the strip-shaped heating chip, the positive arc conductive sheet, the negative arc conductive sheet, the positive pin, and the negative pin. The three positive connection points are connected together through the positive arc conductive sheet to form a unified positive electrical point. The three negative connection points form a unified negative electrical point through the negative arc conductive sheet, which simplifies the circuit structure and improves the current transmission efficiency. The positive arc conductive sheet and the negative arc conductive sheet are cleverly arranged on the base to ensure the shortness and high efficiency of the current path. With such a design, a fan-shaped light-emitting structure can be formed on the base through multiple light-emitting points, with a good perspective effect of the emitted light, significantly improving the overall light efficiency. Compared with a single light-emitting chip or a centralized set of light-emitting chips, the uniformity and irradiation range of the light are effectively diffused and enhanced, and brighter and more uniform light can be emitted.

[0031] In this embodiment, the LED lamp beads with multiple light-emitting points further include a package body; the base, three strip-shaped heating chips, the positive arc conductive sheet, the negative arc conductive sheet, and the upper ends of the positive electrode pin and the negative electrode pin are covered and formed into an integral body by the package body. The package body not only protects the internal light-emitting chips, but also improves its optical, electrical and mechanical properties, effectively improving the light efficiency and brightness of the LED lamp beads, and enabling them to meet the requirements of different lighting applications.

[0032] In order to strengthen the stable and reliable connection of the structure, have good electrical conductivity, be convenient for installation, and have high production efficiency, the positive arc conductive sheet and the positive electrode pin, and the negative arc conductive sheet and the negative electrode pin are integrally formed.

[0033] Preferably, the top view angle of the base is fan-shaped; the top view angle of the package body is fan-shaped. Designing the base and the package body in this way can better arrange the positions of the three light-emitting chips. Not only is the space of the base effectively utilized, but compared with the concentrated arrangement of the light-emitting chips, through the fan-shaped arrangement, the uniformity and irradiation range of the light can be effectively diffused and enhanced. Under the shape design of the base and the package body, the uniformity and irradiation range of the light are effectively diffused and enhanced, and brighter and more uniform light can be emitted.

[0034] In this embodiment, the package body is made of epoxy resin or filled silicone. The package body is a transparent or semi-transparent structure. Such a setting of the package body can achieve the effects of waterproofing, moisture-proofing, anti-corrosion, sealing, filling and insulation.

[0035] In summary, the embodiment of the present utility model provides an LED lamp bead with multiple light-emitting points. Among them, the LED lamp bead with multiple light-emitting points combines a base, strip-shaped heating chips, a positive arc conductive sheet, a negative arc conductive sheet, a positive electrode pin and a negative electrode pin. The three positive connection points are connected together through the positive arc conductive sheet to form a unified positive electrode point, and the three negative connection points form a unified negative electrode point through the negative arc conductive sheet, simplifying the circuit structure and improving the current transmission efficiency. The positive arc conductive sheet and the negative arc conductive sheet are cleverly arranged on the base to ensure the shortness and efficiency of the current path. Such a design can form a fan-shaped light-emitting structure through multiple light-emitting points on the base, with a good perspective effect of the emitted bright light, significantly improving the overall light efficiency. Compared with a single light-emitting chip or a concentrated arrangement of light-emitting chips, the uniformity and irradiation range of the light are effectively diffused and enhanced, and brighter and more uniform light can be emitted.

[0036] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present application.
