Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to assembly, LED filament bulb that production cost is lower, its profile is the same with conventional incandescent, can use the incandescent lamp assembly technology of existing maturation, realize mechanized operation, thereby greatly improve the production efficiency of LED bulb.
The technical solution that the utility model proposes is such:
A kind of LED filament bulb, comprise cell-shell 1, stem stem 2, LED driving power 3, lamp holder 4 and LED filament 6, article at least two, perpendicular LED filament 6 one end of putting be located at stem stem 2 on the connector 5 on top be connected, its other end the 1st in ensconcing stem stem base 2-1 with embedding respectively drawn wire 2-2 and the 2nd and drawn wire 3-4 one end and be connected, described stem stem 2 seals and vacuumizes in connecting portion scorification with cell-shell 1, become vacuum seal cavity, this chamber is filled with helium, nitrogen or high heat-conducting gas, electric capacity in the resistance-capacitance depressurization rectification circuit of composition LED driving power 3 adopts minitype high voltage patch capacitor, constant-current circuit adopts small-sized integrated chip, be welded on the wiring board mating with described cell-shell 1 opening part, become LED driving power circuit plate 13, this LED driving power circuit plate 13 is placed on cell-shell 1 opening part, the lamp holder 4 of coupling is inserted in and is cemented in cell-shell 1 opening part, the described the 1st draws wire 2-2 and the 2nd draws the wire 2-4 other end and is connected with LED driving power 3 outputs, the external AC power supply of lamp holder 4 is connected with LED driving power 3 inputs by wire.
Described LED driving power circuit plate 13 be shaped as circle.Cell-shell 1 can be A shape bubble or B shape bubble or C shape bubble or G shape bubble or T shape bubble or R shape bubble or M shape bubble.Cell-shell 1 can be transparent bubble or frosted bubble or dusting bubble.
Compared with prior art, the utlity model has following beneficial effect:
Due to by integrated LED driving power, bulky electrochemical capacitor is made to minitype high voltage patch capacitor, so the components and parts of LED driving power can be mounted on the circular wiring board mating with E14 lamp holder, its thickness is only 2mm left and right, lamp holder inner chamber is enough to hold and is fixed in cell-shell opening part, thereby has simplified widely mounting structure and the mounting process of LED driving power.Compared with existing LED filament bulb, this LED filament bulb, without using plastic casing to remove to connect cell-shell and lamp holder, has reduced linkage editor, has saved production cost.Assembly technology is identical with conventional incandescent, can realize mechanized operation, improves efficiency of assembling.Also consistent with conventional incandescent in profile, can ideally replace traditional incandescent lamp.
