Description

Technical Field

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

[0002] Incandescent bulbs are a new type of light source that replaces traditional incandescent bulbs. The heat sink, as a crucial component, is used to quickly dissipate the heat generated during bulb operation, and its heat dissipation efficiency directly affects the quality of the bulb. In typical bulbs, the heat sink is a heat sink cup, housed within the bulb shell. The lamp plate is housed within the heat sink cup, with the edge of the lamp plate contacting the inner wall of the heat sink cup. Heat generated by the lamp plate is dissipated through the heat sink cup. This structure results in a relatively small contact area between the lamp plate and the heat sink cup, leading to low heat dissipation efficiency for the lamp plate. Furthermore, the heat sink cup's large size, designed to support the lamp plate, hinders cost reduction. Utility Model Content

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-5 As shown, this utility model embodiment provides a bulb lamp, including a bulb shell 1, a lamp board 2, and a heat sink 3.

[0037] The bulb 1 has an annular opening at one end along its axial direction, and an annular support 11 is provided on the inner wall of the bulb 1. The annular support 11 is distributed close to the annular opening. The lamp plate 2 is installed inside the bulb 1 through the annular opening and supported on the annular support 11. The heat sink 3 is disposed inside the bulb 1 and is attached to the side of the lamp plate 2 facing the bulb 1. The heat sink 3 has a cavity inside, which is filled with a heat dissipation medium. It can be understood that the axial direction of the bulb 1 is the direction extending along the center line of the bulb 1, which is the straight line passing through the centers of the two ends of the bulb 1 (refer to...). Figure 2 ).

[0038] By mounting the lamp plate 2 on the annular support 11, a portion of the heat generated by the lamp plate 2 can be dissipated through the bulb 1. Furthermore, the heat sink 3 is attached to the lamp plate 2, increasing the contact area between them. The cavity of the heat sink 3 is filled with a heat-dissipating medium, allowing another portion of the heat generated by the lamp plate 2 to be dissipated through the heat sink 3. This bulb not only increases the contact area between the lamp plate 2 and the heat sink 3, but also allows the heat from the lamp plate 2 to be dissipated through the bulb 1, effectively increasing heat dissipation efficiency. Moreover, the molding process of the heat sink 3 is simple and the cost is low.

[0039] Optionally, when installing the lamp panel 2, glue can be applied to the annular support 11 first, and then the lamp panel 2 can be placed on the annular support 11 to bond the lamp panel 2 to the annular support 11 and prevent the lamp panel 2 from shaking.

[0040] In this embodiment, as Figure 5 and combined Figures 2-4 As shown, the bulb lamp also includes a circuit board module 4 disposed inside the bulb shell 1. A spring antenna 41 is disposed at one end of the circuit board module 4 near the lamp board 2. In order not to affect the signal transmission of the spring antenna 41, the heat sink 3 is provided with a second through hole 31, the lamp board 2 is provided with a first through hole 21, the end of the circuit board module 4 near the lamp board 2 extends into the second through hole 31, and the spring antenna 41 passes through the first through hole 21 and extends to the outside of the bulb shell 1.

[0041] Optionally, the heat sink 3 is made of plastic, that is, the heat sink 3 is made of plastic material. Plastic material causes less interference to the spring antenna 41 and transmits signals better.

[0042] The bulb lamp also includes a lamp holder 6, which is located on the outside of the bulb shell 1 and connected to the other end of the bulb shell 1 along its axial direction. The lamp holder 6 is used to install on the lamp holder to realize the installation of the bulb lamp.

[0043] To facilitate the installation of the circuit board module 4, a plug-in slot 12 is provided on the inner side of the other end of the bulb 1 along its axial direction. Two plug-in slots 12 can be symmetrically arranged. Each plug-in slot 12 is composed of two spaced-apart inserts. The other end of the circuit board module 4 is plugged into the two symmetrically arranged plug-in slots 12 and electrically connected to the lamp holder 6. The plug-in slots 12 make the installation of the circuit board module 4 convenient and quick.

[0044] Optionally, the heat sink 3 is provided with a communication port 32 that communicates with the cavity. The heat dissipation medium is filled into the cavity through the communication port 32. By opening the communication port 32 on the heat sink 3, it is convenient to fill the heat dissipation medium and the opening operation is relatively simple, which can effectively improve the processing and manufacturing efficiency of the heat sink 3.

[0045] Optionally, the heat dissipation medium is thermally conductive adhesive, which has good thermal conductivity and electrical insulation properties. While taking into account thermal conductivity, thermally conductive adhesive also has electrical insulation properties, which can effectively avoid signal interference to the spring antenna 41.

[0046] Optionally, the lamp panel 2 is provided with two first connecting holes 22, and the heat sink 3 is provided with two second connecting holes 33 corresponding to the first connecting holes 22. Fasteners 34 connect the lamp panel 2 and the heat sink 3 through the corresponding first connecting holes 22 and second connecting holes 33. The heat sink 3 is connected to the lamp panel 2 by the fasteners 34, which facilitates installation.

[0047] In this embodiment, the first connecting hole 22 is a through hole, and the second connecting hole 33 is a threaded hole. The fastener 34 can be a screw, which is inserted through the through hole and screwed into the threaded hole to connect the heat sink 3 and the lamp board 2. Of course, the lamp board 2 can also have more than two first connecting holes 22, and the heat sink 3 can have multiple corresponding second connecting holes 33.

[0048] In this embodiment, refer again Figure 1 As shown, the bulb lamp also includes a lampshade 5, which is inserted into the annular opening of the bulb shell 1 and abuts against the lamp plate 2. The lampshade 5 presses against the lamp plate 2, making the lamp plate 2 more stable.

[0049] Furthermore, the lampshade 5 is provided with an annular snap-fit ​​part 51 at the end facing the bulb 1, and an annular groove 13 is provided on the inner side of the bulb 1 at the end facing the lampshade 5. The annular snap-fit ​​part 51 is inserted into the annular groove 13, and the lamp plate 2 is sandwiched between the annular support part 11 and the annular snap-fit ​​part 51.

[0050] Optionally, the bubble shell 1 is filled with a heat dissipation medium (which may be thermal adhesive), and the heat dissipation medium is attached to the inner wall of the bubble shell 1. A portion of the circuit board module 4 is wrapped in the heat dissipation medium. By setting the heat dissipation medium inside the bubble shell 1, the heat generated by the circuit board module 4 is transferred to the bubble shell 1 through the heat dissipation medium, so that the heat dissipation medium can assist in heat dissipation and further improve the heat dissipation efficiency.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
