[0003] In related technologies, a lamp bulb heat dissipation structure is disclosed in Chinese Utility Model Patent No. CN220397454U. The structure includes a shell, a lamp panel, and a heat dissipation piece. The shell is hollow, the lamp panel is arranged at one end of the shell, the lamp panel has a bottom surface facing the inside of the shell and a light-emitting surface facing the outside of the shell, and the heat dissipation piece is arranged in the shell and in contact with the bottom surface.

[0004] In the above related technology, the heat dissipation piece is located inside the shell, and the inside of the shell is a relatively closed chamber, so that the heat on the heat dissipation piece is not easily dissipated from the inside of the shell and remains inside the shell, thereby reducing the heat dissipation effect of the lamp bulb. SUMMARY

DETAILED DESCRIPTION

[0024] The following description will be made in conjunction with the accompanying drawings. Figures 1-4 The application is further described in detail.

[0025] The application discloses an energy-saving lamp with good heat dissipation. Referring to Figure 1 With Figure 2 , the energy-saving lamp with good heat dissipation comprises a lamp holder 1, a lampshade 2 and a lamp panel 3. The lamp panel 3 is provided with a heat dissipation member 31, and the lamp panel 3 and the heat dissipation member 31 are both mounted in the lamp holder 1. The lampshade 2 covers the lamp panel 3 and is mounted on the lamp holder 1. The outer wall of the lamp holder 1 is provided with heat dissipation holes 11 that are in communication with the inside of the lamp holder 1. The heat generated by the lamp panel 3 is conducted to the heat dissipation member 31, and the heat on the heat dissipation member 31 can be exchanged with the airflow outside the lamp holder 1 through the heat dissipation holes 11, thereby improving the heat dissipation effect of the lamp panel 3.

[0026] Referring to Figure 1 With Figure 2 , the lamp holder 1 is made of a heat-conducting material, so the heat on the heat dissipation member 31 can be conducted to the lamp holder 1. One end of the lamp holder 1 is provided with a threaded joint 12, and the lamp holder 1 can be mounted on a corresponding lamp through the threaded joint 12. The end of the lamp holder 1 away from the threaded joint 12 is provided with a mounting groove 13, and the lamp panel 3 is mounted on the groove bottom of the mounting groove 13 through screws. The side of the lamp panel 3 away from the mounting groove 13 is provided with a plurality of lamp beads, and the plurality of lamp beads are arranged circumferentially on the lamp panel 3. The heat dissipation member 31 is located on the side of the lamp panel 3 away from the lamp beads, and the heat dissipation member 31 is mounted on the lamp panel 3 through bolts, so that the high temperature generated by the lamp panel 3 can be conducted to the heat dissipation member 31 in time.

[0027] The side of the lampshade 2 close to the lamp holder 1 is provided with a threaded convex edge 21 inserted into the mounting groove 13, and the groove wall of the mounting groove 13 is provided with an internal thread that is screwed with the threaded convex edge 21, so that the lampshade 2 can be screwed onto the lamp holder 1 after covering the lamp panel 3.

[0028] Referring to Figure 2 With Figure 3The mounting groove 13 has a heat dissipation chamber 14 at its bottom. The inner diameter of the heat dissipation chamber 14 is smaller than the outer diameter of the lamp plate 3, so that the lamp plate 3 can completely block the opening of the heat dissipation chamber 14. The heat sink 31 is inserted into the heat dissipation chamber 14, and the heat sink 31 and the circumferential wall of the heat dissipation chamber 14 are clearance-fitted. The heat dissipation holes 11 are connected to the heat dissipation chamber 14, so that the heat on the heat sink 31 can be discharged in time through the heat dissipation holes 11. Multiple heat dissipation holes 11 are provided, and the multiple heat dissipation holes 11 are evenly distributed along the circumference and extension direction of the lamp holder 1, and all the multiple heat dissipation holes 11 are connected to the heat dissipation chamber 14.

[0029] In addition, by blocking the opening of the heat dissipation chamber 14 through the lamp plate 3, some dust enters the heat dissipation chamber 14 through the heat dissipation hole 11 and is then connected to the side of the lamp plate 3 where the heat sink is located, thus making it difficult for dust to enter the lamp cover 2 and affect the lighting effect.

[0030] Reference Figure 2 and Figure 3 The lamp holder 1 has integrally formed heat dissipation fins 15 on its outer peripheral wall. Multiple heat dissipation fins 15 are arranged circumferentially at intervals on the lamp holder 1, and all are located on the outer peripheral wall of the heat dissipation chamber 14. Heat transferred from the heat sink 31 to the heat dissipation chamber 14 is then conducted to the multiple heat dissipation fins 15, allowing for rapid heat dissipation. To prevent the heat dissipation fins 15 from affecting the heat dissipation holes 11, heat dissipation holes 11 are provided between any two circumferentially adjacent heat dissipation fins 15.

[0031] Reference Figure 2 and Figure 3 The heat dissipation chamber 14 is equipped with a filter sleeve 16. The filter sleeve 16 is made of a material with a certain deformation capability. The filter holes in the filter sleeve 16 are particularly smaller than the aperture of the heat dissipation holes 11. Thus, the filter sleeve 16 can isolate most of the dust in the air without affecting the airflow inside and outside the heat dissipation chamber 14, making it difficult for dust to enter the heat dissipation chamber 14.

[0032] Reference Figure 2 and Figure 3 A retaining ring 17 is integrally formed on the cavity wall of the heat dissipation chamber 14. The retaining ring 17 is located on the side of the heat dissipation chamber 14 near the cavity opening. After the filter sleeve 16 is installed in the heat dissipation chamber 14, one end of the filter sleeve 16 abuts against the bottom of the heat dissipation chamber 14, and the other end abuts against the side of the retaining ring 17 near the bottom of the heat dissipation chamber 14, thereby limiting the filter sleeve 16 and preventing circumferential movement. In addition, the outer peripheral wall of the filter sleeve 16 abuts against the inner peripheral wall of the heat dissipation chamber 14. This arrangement limits the radial direction of the filter sleeve after installation and prevents it from shaking.

[0033] Combination Figure 2 Reference Figure 3 and Figure 4 The blocking ring 17 has an inclined surface 171 on the side near the lamp panel 3. The inclined surface 171 gradually slopes towards the inner wall of the heat dissipation chamber 14 along the direction in which the filter sleeve 16 is pulled out from the heat dissipation chamber 14. When installing the filter sleeve 16, the outer edge of the filter sleeve 16 near the bottom of the heat dissipation chamber 14 abuts against the inclined surface 171. Then, a pushing force is applied to the filter sleeve 16 to move it towards the bottom of the heat dissipation chamber 14. The filter sleeve 16 will deform and enter the heat dissipation chamber 14 relatively smoothly. After the filter sleeve 16 passes through the blocking ring 17 and enters the heat dissipation chamber 14, it will automatically reset under its own elasticity.

[0034] The implementation principle of an energy-saving lamp with good heat dissipation according to an embodiment of this application is as follows: Since the lamp holder 1 is made of a thermally conductive material, the heat generated by the lamp plate 3 is conducted to the heat dissipation chamber 14 through the heat sink 31, and the heat in the heat dissipation chamber 14 is then conducted to the heat dissipation fins 15 of the lamp holder 1 for heat dissipation. In addition, the hot airflow in the heat dissipation chamber 14 can be discharged through the heat dissipation holes 11, and at the same time, the airflow outside the lamp holder 1 can also enter the heat dissipation chamber 14 through the heat dissipation holes 11, thereby improving the heat dissipation effect inside the bulb. The filter sleeve 16 can block the heat dissipation holes 11, making it difficult for dust in the air to enter the heat dissipation chamber 14 through the heat dissipation holes 11.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
