Preferably, described radiator also comprises base, and fin, radiating ribs, space all are positioned at the top of base.

Preferably, the below of described base is provided with the protuberance of hollow, and described LED lamp plate is fixed on the outer surface of described protuberance, and the inner surface of described protuberance is provided with heat radiation layer.

Preferably, described protuberance is shaped as polygonal shape.

Preferably, fixedly there is the LED lamp plate on the surface of described protuberance, and the LED lamp plate is provided with a plurality of LED.

Preferably, described LED bulb lamp also comprises diffuser, and the top of diffuser is provided with grab, and the inboard of base is provided with buckle, and when diffuser and base combined, grab engaged with buckle.

Preferably, described LED bulb lamp also comprises lamp socket, and an end and the radiating ribs of lamp socket are fixed, and radiating ribs is provided with screw hole, and the side of lamp socket is provided with through hole, and through hole and screw hole are located along the same line.

Preferably, described LED bulb lamp also comprises lamp holder, and the other end of lamp socket is connected with cap screw thread.

Positive progressive effect of the present utility model is: the space of the radiator in the utility model makes the cross-ventilation effect improve greatly, the inner surface of the hollow protrusion of foot of radiator is coated with heat radiation layer simultaneously, the heat that this heat radiation layer sends the LED lamp plate in time is transmitted to above fin, the radiating ribs etc., increase radiating rate, improve radiating effect.Improve radiating effect like this, increase the service life of the utility model LED bulb lamp.In addition, the utility model is enhanced productivity by grab and buckle ease of assembly and dismounting, and prevents that diffuser and radiator are loosening and cause coming off.

The specific embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the utility model LED bulb lamp comprises radiator 1, radiator 1 comprises a plurality of fin 11 and a plurality of radiating ribs 12, fin 11 and radiating ribs 12 be spaced and fin 11 and radiating ribs 12 between be provided with space 13.Radiator 1 also comprises the protuberance 15 of base 14 and hollow, fin 11, radiating ribs 12, space 13 all are positioned at the top of base 14, protuberance 15 is positioned at the below of base 14, the inner surface of protuberance 15 is provided with heat radiation layer 151, and heat radiation layer is black paint or uses black specialty thermal-radiating material (such as copper, carbon etc.) to make.Protuberance 15 be shaped as polygonal shape (such as being pentagon in this example).The outer surface of protuberance 15 fixedly has LED lamp plate 5, and LED lamp plate 5 is provided with a plurality of LED illuminators 6.In addition, radiating ribs 12 is provided with screw hole 121.The inboard of base 14 is provided with a plurality of buckles 16.

As Fig. 1, Fig. 7, shown in Figure 8, the utility model LED bulb lamp also comprises diffuser 4, and the top of diffuser 4 is provided with a plurality of grabs 41, and when diffuser 4 and base 14 combined, grab 41 engaged with buckle 16.The top of grab 41 is provided with hypotenuse 411.The bottom of grab 41 can be provided with positioning bar 412, and positioning bar 412 can prevent effectively that diffuser from rotating too along clockwise direction.The centre of grab 41 is provided with groove 413, groove 413 is between hypotenuse 411 and positioning bar 412, grab 41 is with after buckle 16 engages, buckle 16 is positioned at groove 413, buckle 16 just can not move like this, thereby guarantee that diffuser 4 and radiator 1 are fixed, hypotenuse 411 makes things convenient for buckle 16 to be slipped in the groove 413.
