The utility model belongs to field of illumination lamp technology, is specifically related to a kind of LED lighting technology.
Background technology
The LED illuminating lamp is because green energy conservation is used widely.The structure of LED lamp is mostly identical, comprises lamp holder, lamp housing and led chip, and lamp holder is connected with lamp housing, and led chip is installed in the lamp housing.The subject matter of existing LED lamp is that radiating effect is poor, and the heat that produces during led chip work can not be discharged fast and be caused led chip short service life.
Summary of the invention
The purpose of this utility model is: the deficiency for prior art exists, a kind of novel structure is provided, and easy to assembly, the LED lamp of good heat dissipation effect.
For realizing the purpose of the utility model, be achieved by the following technical solutions: a kind of LED lamp, the lamp housing of the plastic material that includes lamp holder and be connected with lamp holder, the lamp housing end face is cylindrical, lamp housing is provided with a plurality of grafting bars along its length, form slot between adjacent two grafting bars, be plugged with strip line road plate in the slot, be welded with led chip on the bar shaped wiring board; Be connected with cancave cambered surface between adjacent two grafting bars; The end of grafting bar is connected with the end cap of annular, is provided with circular wiring board in the end cap, also is welded with led chip on the circular wiring board.
As preferred version: described bar shaped wiring board is provided with 8, evenly is provided with 6 led chips on the every bar shaped wiring board; Described circular wiring board is provided with 12 led chips, and wherein 4 led chips are positioned on the circumference, and other 8 led chips are positioned on another circumference, and two circumference concentrics and the center of circle are positioned at the center of circular wiring board.
As preferred version: the end of described grafting bar is provided with spliced eye, and described end cap is provided with the connection-peg that cooperates with spliced eye.
As preferred version: described lamp housing is the arcwall face of indent near the side of lamp holder.
As preferred version: be provided with drive circuit board in the described lamp housing, lamp holder and led chip are connected with the corresponding port of drive circuit board respectively.
Compared with prior art, the beneficial effects of the utility model are: described bar shaped wiring board can be inserted in the slot that forms between adjacent two grafting bars easily, the end that end cap is plugged into the grafting bar is completely fixed the bar shaped wiring board, and also be provided with led chip on the end cap, this LED lamp brightness is high like this, easy to assembly, and heat radiation is good.
