Preferably, light source assembly comprises that being close to light source is provided with on the face and the circuit board that is electrically connected with drive unit, is located at the LED lamp pearl on the circuit board.
Preferably, the draw-in groove of square all is " L " type, or all is minute surface " L " type.
Preferably, projection is shaped as strip, square or cylindrical.
Preferably, the quantity of projection is 1 to 5.
Preferably, the light source of lampholder cover is provided with that the center is provided with the line hole on the face, and line hole periphery is provided with some screws that are used to install and fix circuit board.
Preferably, lampholder shell, lampholder cover are made by heat sink material pottery or metal, and are integrated formed structure.
Preferably, diffuser is set to enclosed globe shade, tip candle cover or draws tail candle cover.
A kind of LED bulb of the utility model, be fixedly connected with lamp holder, holder structure, light source assembly from the bottom to top successively, be located at the outer diffuser of light source assembly, also comprise and be located in the holder structure and the drive unit that is electrically connected with light source assembly, holder structure comprises the lampholder shell that is connected with lamp holder, the lampholder cover that is connected with the lampholder shell upper end, the lampholder cover upper surface is that light source is provided with face, the lampholder cover lateral surface is provided with some projections, and the lampholder shell upper end open is provided with the draw-in groove of adaptive with projection and the mutual square that engages in the position of projection correspondence.So simple structure makes lampholder shell and lampholder cover engage by projection and draw-in groove mutual and is connected and fixed, and is easy and simple to handle, can easily finish the assembly and disassembly work of holder structure, and the engaging mode is more firm, and service life is longer.
Description of drawings
Fig. 1 is the stereochemical structure decomposing schematic representation of an embodiment of a kind of LED bulb of the utility model;
Fig. 2 is the perspective view of lampholder shell among the embodiment of a kind of LED bulb of the utility model.
The realization of the utility model purpose, functional characteristics and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to figs. 1 through Fig. 2, one embodiment of a kind of LED bulb of the present utility model is proposed, be fixedly connected with lamp holder 100, holder structure, light source assembly (not shown in the accompanying drawing) from the bottom to top successively, be located at the outer diffuser 300 of light source assembly, also comprise and be located in the holder structure and the drive unit that is electrically connected with light source assembly.Wherein, diffuser 300 is set to enclosed globe shade, tip candle cover or draws tail candle cover.
Holder structure comprises the lampholder shell 201 that is connected with lamp holder 100, the lampholder cover 202 that is connected with lampholder shell 201 upper ends, lampholder cover 202 upper surfaces are that light source is provided with face, lampholder cover 202 lateral surfaces are provided with some projections 203, and lampholder shell 201 upper end open are provided with the draw-in groove 204 of and the mutual square that engage adaptive with projection 203 in the position of projection 203 correspondences.The draw-in groove 204 of square all is " L " type, or all is minute surface " L " type.The quantity of projection 203 is 1 to 5, and the projection 203 of present embodiment is set to 3.
