Compared with the prior art, the utility model, its advantage lies in: only comprise metal lamp holder, metal radiator, circuit board, circuit board and metal radiator pass through welding pieces welded fastening, and the external diameter of metal radiator is connected through getting ready with the internal diameter of metal lamp holder, simple structure, and the assembly is simple and convenient, improves the automatic efficiency of equipment to reduce manufacturing cost, can effectively increase light -emitting diode (LED) bulb lamp's radiating effect, prolong light -emitting diode (LED) bulb lamp's life.
Description
[technical field]
The utility model relates to technical field of LED illumination, specifically a kind of LEDbulb lamp.
[background technology]
Along with LED lamp is more and more universal, and LEDbulb lamp is widely used in various occasion because it has energy-conservation, life-span long, light efficiency high, due to LEDbulb lamp work time, only have small part electric energy conversion to be luminous energy, most of electric energy all because heat radiation is bad be converted into heat energy, causes energy utilization rate low, and structural elements is more, assembly cost is high, and automaticity is low, so the automated production of LEDbulb lamp is at present the emphasis of research.
[summary of the invention]
The utility model is in order to the not enough and defect that overcomes that the parts that existing LEDbulb lamp exists are more, radiating effect is not good etc., provides the LEDbulb lamp that a kind of good heat dissipation effect, structure are simple, ease of assembly is produced.
To achieve these goals, design a kind of LEDbulb lamp, comprise metallic lamp holder, metal heat sink, wiring board, wiring board offers a pad hole, metal heat sink upper surface is provided with bonding pad, bonding pad position on metal heat sink is corresponding with the pad hole site on wiring board, and the external diameter of metal heat sink and the diameter compatible of metallic lamp holder close, by getting connection ready.
Described bonding pad, through pad hole, utilizes scolding tin or conducting resinl to be connected on pad hole by bonding pad.
Be provided with wire bottom described wiring board, wiring board base conductor is inserted in the through hole in the middle part of metal heat sink.
Described LEDbulb lamp also comprises electrode, one end of electrode is conducting to metal heat sink from the whorl side of metallic lamp holder, be conducting on wiring board by scolding tin or conducting resinl by the bonding pad of metal heat sink again, the other end of electrode is conducting to wiring board from the top of metallic lamp holder by wire.
The utility model compared with the existing technology, its advantage is: be only made up of metallic lamp holder, metal heat sink, wiring board, wiring board and metal heat sink are welded and fixed by bonding pad, the external diameter of metal heat sink is connected by getting ready with the internal diameter of metallic lamp holder, and structure is simple, assembles easy, improve assembling automation efficiency, thus minimizing production cost, effectively can increase the radiating effect of LEDbulb lamp, extend the service life of LEDbulb lamp.
