Description

Technical Field

[0001] The utility model relates to the technical field of lamp holders, in particular to a lamp holder with a high-efficiency heat dissipation structure. Background Art

[0002] The lamp holder refers to the interface connected to the end of the electric light cord for installing the bulb, which should be used with caution. The electric light source mainly uses the lamp holder and lamp holder naming method. The lamp holder is the end of the bulb, which is the connecting part between the light source and the external power supply. The light source is connected to the electricity through the lamp holder to produce light. The light source body mainly includes lamp beads, bulbs, and lamp tubes, among which the lamp tubes include straight lamp tubes and curved lamp tubes. Lamp beads are mainly the light source form of LED lamps, and the bulbs are generally incandescent lamps, fluorescent lamps, halogen tungsten lamps, LED bulbs, etc., and the lamp tubes are mainly common fluorescent lamps. When the lamp emits light, it will generate heat, so the heat dissipation of the lamp holder is a very critical part of the lamp design, and the quality of its heat dissipation directly affects the performance and service life of the lamp. In order to facilitate production, the existing lamp holder generally adopts an integrated structure, but this structure greatly affects the heat dissipation and seriously affects the service life of the lamp. In view of this, we propose a lamp holder with an efficient heat dissipation structure. Utility Model Content

[0015] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0016] See also Figure 1-Figure 3 As shown, the purpose of this embodiment is to provide a lamp holder with an efficient heat dissipation structure, including a ceramic base 1 and a shell 2 and a fixing thread 3 surrounding the shell 2, the fixing thread 3 makes the connection between the lamp holder and the lamp holder more stable, the ceramic base 1 is welded with a copper joint 111, and the ceramic base 1 is provided with a plurality of base heat dissipation holes 112, thereby enhancing the heat dissipation efficiency;

[0017] The ceramic base 1 is welded to the lower end of the housing 2. The housing 2 is provided with a plurality of heat dissipation holes 211. The housing 2 is made of heat-conducting copper, which enhances the heat dissipation capacity of the lamp.

[0018] A wick base 4 is fixedly connected inside the shell 2, and a ceramic heat dissipation tube 5 is connected to the wick base 4 through a connecting rod 412. The interior of the ceramic heat dissipation tube 5 is hollow, which makes the heat dissipation effect better. A thread 411 is provided on the wick base 4, and a heat dissipation fin 6 is threadedly connected through the thread 411. Such a structure is convenient for installation and replacement. The heat dissipation fin 6 is made of thermally conductive copper sheet, and the heat generated by the lamp can be better radiated through the heat dissipation fin.

[0019] A light emitting element 7 is fixedly connected to the upper end of the ceramic heat dissipation tube, and a copper wire 711 is welded on the light emitting element 7. The copper wire 711 surrounds the ceramic heat dissipation tube 5, so that the heat generated by the light emitting element 7 can be better conducted to the ceramic heat dissipation tube 5 and dissipated by the ceramic heat dissipation tube 5.

[0020] Working principle: the light-emitting element 7 generates heat while emitting light. A copper wire 711 is welded on the light-emitting element 7. The copper wire 711 is wrapped around the ceramic heat dissipation tube 5. In this way, the heat generated by the light-emitting element 7 will be conducted to the ceramic heat dissipation tube 5 by the copper wire 711. Because the inside of the ceramic heat dissipation tube 5 is hollow, the heat dissipation effect is better. The ceramic heat dissipation tube 5 is surrounded by heat dissipation fins 6. The material of the heat dissipation fins 6 is a thermally conductive copper sheet, which can better radiate heat. In addition, a number of heat dissipation holes 211 are provided on the outermost shell 2, and a number of base heat dissipation holes 112 are also provided on the ceramic base 1, which will also assist in heat dissipation.
