Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving lamps, in particular to a heat dissipation mechanism for energy-saving lamps. Background Art

[0002] When energy-saving lamps are working, the lamp chip will generate a lot of heat. If the heat cannot be dissipated in time and effectively, it will lead to problems such as shortened lamp life and reduced light efficiency. As an important part of the heat dissipation system, the role of the lamp radiator cannot be ignored. The lamp radiator can help the lamp dissipate heat quickly and ensure its normal operation, thereby increasing the lamp's service life and light efficiency.

[0003] The existing public technical solution, with announcement number CN220287290U, discloses a spiral lamp holder of an energy-saving lamp. Through the setting of the heat dissipation mechanism, the heat generated by the energy-saving lamp body can be transferred to the semicircular heat-conducting ring through the heat-conducting strip, and then transferred to the coolant pipe. The cooling liquid in the coolant pipe can effectively absorb the heat and dissipate it to the surrounding environment, thereby cooling the energy-saving lamp body, avoiding overheating of the energy-saving lamp body and causing damage, and maintaining normal working temperature.

[0004] When the above technical solution is actually implemented, the heat dissipation mechanism is fixedly arranged inside the spiral lamp holder, which means that the heat dissipation mechanism needs to be connected to the lamp holder before leaving the factory. The heat dissipation mechanism cannot be directly installed on the energy-saving lamp independently, and the heat dissipation mechanism cannot be directly added to the existing energy-saving lamp to improve the heat dissipation effect of the energy-saving lamp. Summary of the invention

[0005] The purpose of the utility model is to provide a heat dissipation mechanism for an energy-saving lamp, which can be independently installed outside the energy-saving lamp to improve the heat dissipation effect of the energy-saving lamp, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solutions: a heat dissipation mechanism of an energy-saving lamp, comprising a lampshade, a radiator is arranged below the lampshade, a connecting shell is arranged below the radiator, a lamp holder is arranged below the connecting shell, and an external heat dissipation component is arranged on the outside of the connecting shell;

[0007] The external heat dissipation component includes a mounting plate, and a fixing plate is arranged on one side of the mounting plate, a heat-conducting inner ring is arranged between two groups of the fixing plates, and a buffer inner pad is arranged on one side of the heat-conducting inner ring, and a heat dissipation fin is arranged on the other side of the heat-conducting inner ring, and fixing screws are passed through the interior of the mounting plate.

[0008] Preferably, a mounting hole is provided inside the mounting plate, and a fixing screw passes through the mounting hole and is threadedly connected to a matching nut.

[0009] Preferably, the fixing plate and the mounting plate are an integrated structure, and the fixing plate and the mounting plate are made of plastic.

[0010] Preferably, the buffer inner pad is made of silicone rubber, and the buffer inner pad and the connecting shell are in close contact with each other.

[0011] Preferably, the heat-conducting inner ring is made of alumina ceramic material, and the buffer inner pad is fixedly bonded to the heat-conducting inner ring.

[0012] Preferably, the heat dissipation fins are evenly distributed at equal intervals outside the heat-conducting inner ring, and the outer diameter of the heat dissipation fins is smaller than the outer diameter of the radiator.

[0013] Preferably, the exterior of the lamp holder is provided with an external thread.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting up an external heat dissipation component, since the external heat dissipation component is independently installed on the outside of the energy-saving lamp, the external heat dissipation component is in contact with the connecting shell and the radiator of the energy-saving lamp, the heat of the energy-saving lamp can be introduced into the external heat dissipation component through the radiator and the connecting shell, and the heat dissipation effect of the energy-saving lamp is increased by the external heat dissipation component;

[0016] 2. The buffer inner pad and the heat-conducting inner ring are both thermally conductive and insulating, which can improve the thermal conductivity of the external heat dissipation component. The external heat dissipation component is installed inside the mounting plate by fixing screws. The distance between the mounting plates can be adjusted according to the connecting shells of different diameters, which is convenient for the installation of the external heat dissipation component.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a technical solution:

[0026] See also Figures 1 to 4 , a heat dissipation mechanism of an energy-saving lamp, comprising a lampshade 1, a radiator 2 is arranged below the lampshade 1, a connecting shell 5 is arranged below the radiator 2, a lamp holder 3 is arranged below the connecting shell 5, and an external heat dissipation component 4 is sleeved on the outside of the connecting shell 5;

[0027] The external heat dissipation component 4 includes a mounting plate 401, and a fixing plate 406 is arranged on one side of the mounting plate 401, a heat-conducting inner ring 404 is arranged between two sets of fixing plates 406, and a buffer inner pad 405 is arranged on one side of the heat-conducting inner ring 404, and a heat dissipation fin 403 is arranged on the other side of the heat-conducting inner ring 404, and a fixing screw 402 is passed through the inside of the mounting plate 401.

[0028] By adopting the above technical solution, the external heat dissipation component 4 is independently installed on the outside of the energy-saving lamp, and is in contact with the connecting shell 5 and the radiator 2 of the energy-saving lamp. The heat of the energy-saving lamp can be introduced into the external heat dissipation component 4 through the radiator 2 and the connecting shell 5. The heat dissipation effect of the energy-saving lamp is increased by the external heat dissipation component 4. During installation, the buffer inner pad 405 and the connecting shell 5 are fitted together, and the fixing screws 402 are installed inside the mounting plate 401. According to the connecting shells 5 of different diameters, the distance between the mounting plates 401 is adjusted to facilitate the installation of the external heat dissipation component 4, and the lamp holder 3 is used to install the energy-saving lamp.

[0029] Specifically, Figures 2 to 4As shown, a mounting hole 407 is provided inside the mounting plate 401, and a fixing screw 402 passes through the mounting hole 407 and is threadedly connected to a matching nut, the fixing plate 406 and the mounting plate 401 are an integrated structure, and the fixing plate 406 and the mounting plate 401 are made of plastic, the buffer inner pad 405 is made of silicone rubber, and the buffer inner pad 405 and the connecting shell 5 are fitted together, the thermal conductive inner ring 404 is made of alumina ceramic, and the buffer inner pad 405 is fixedly bonded to the thermal conductive inner ring 404, the heat dissipating fins 403 are evenly distributed on the outside of the thermal conductive inner ring 404, and the outer diameter of the heat dissipating fins 403 is smaller than the outer diameter of the radiator 2, and the outside of the lamp holder 3 is provided with an external thread.

[0030] By adopting the above technical solution, when heat is dissipated, the heat is first transferred to the buffer inner pad 405. Since the buffer inner pad 405 made of silicone rubber has good thermal conductivity and insulation, the heat can be transferred to the thermal conductive inner ring 404, and then transferred to the heat dissipation fins 403 through the thermal conductive inner ring 404. The heat dissipation fins 403 transfer the heat to the external air to fully dissipate the heat. Since the thermal conductive inner ring 404 made of alumina ceramic also has thermal conductivity and insulation, it can further prevent the external heat dissipation component 4 from conducting electricity from the inside to the outside.

[0031] Working principle: When in use, place the buffer inner pad 405 made of silicone rubber close to the connecting shell 5, and pass the fixing screw 402 through the mounting hole 407, and install the nut on the other side of the mounting plate 401 for threaded connection. According to the connecting shell 5 of different diameters, the distance between the mounting plates 401 is adjusted to facilitate the installation of the external heat dissipation component 4. The heat generated by the energy-saving lamp is transferred to the buffer inner pad 405 through the connecting shell 5 and the radiator 2, and is transferred to the heat dissipation fins 403 through the heat-conducting inner ring 404. The heat dissipation fins 403 transfer the heat to the external air for sufficient heat dissipation. Since the buffer inner pad 405 and the heat-conducting inner ring 404 are both thermally conductive and insulating, the thermal conductivity of the external heat dissipation component 4 can be improved.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
