The specific embodiment

Below in conjunction with accompanying drawing, the present invention is further illustrated:

The direction term of mentioning in following examples, for example " upper and lower, left and right " are only the directions with reference to accompanying drawing, therefore, the direction term of use is to illustrate not to be to limit the utility model.

as shown in Figure 1, the LED lampshade, comprise top lampshade 11 and side lampshade, described top lampshade 11 comprises central hemispheroid combined lampshade 111 and peripheral hemisphere lampshade 112, the center of described top lampshade 11 arranges a central hemispheroid combined lampshade 111, the periphery of described central hemispheroid combined lampshade 111 arranges the peripheral hemisphere lampshade 112 in a week, described peripheral hemisphere lampshade 112 is tangent with described central hemispheroid combined lampshade 111, and adjacent peripheral hemisphere lampshade 112 is tangent, the edge of described top lampshade 11 is comprised of described peripheral hemisphere lampshade 112, described side lampshade comprises some arc lampshade bars 9, described arc lampshade bar 9 engages the side lampshade that forms a bar shape with the edge of described top lampshade 11, central hemispheroid combined lampshade 111 as shown in fig. 1 and peripheral hemisphere lampshade 112 arrange at grade, arc lampshade bar 9 engages with the edge of peripheral hemisphere 112, surround a column structure, be combined into a lampshade structure.This lampshade can realize that whole lamp body side 360 degree are luminous, the top of its lamp body also can be luminous evenly.

The radius of described central hemispheroid combined lampshade 111 is greater than the radius of described peripheral hemisphere lampshade 112.The both sides that described arc lampshade is 9 arrange bending part 91, described bending part 91 is to the inside bending of arc lampshade bar 9, as shown in Figure 1, the inside bending in both sides that its bending part 91 is arc lampshade bar 9, this bending part 91 can coordinate the structure of radiator 6 that arc lampshade bar 9 is fixed on radiator 6.

A kind of LED lamp with LED lampshade as shown in Figure 2, comprise LED7, pcb board 8, radiator 6, power supply 2 and lamp holder 1, described LED7 is arranged on described pcb board 8, be arranged on the side and end face of described radiator 6 after described LED7 and 8 combinations of described pcb board, described radiator 6, power supply 2 are connected with lamp holder successively and are connected, at the outer described arbitrary LED lampshade of claim 1-3 that arranges of described radiator 6, described pcb board 8 correspondences of each on radiator 6 sides arrange a described arc lampshade bar 9, and the end face of described radiator 6 arranges top lampshade 11.LED lampshade of the present utility model adopts a plurality of component combinations to consist of, wherein the arc lampshade bar 11 of side surrounds a week, each arc lampshade bar 11 is fixing by mode and the described radiator 6 of engaging, can the dismounting and change lampshade, when damaging, LED7 also is convenient for changing LED7, and simple in structure, very practical, the only corresponding pcb boards 8 of each arc lampshade bar 11, thus can be effectively to the light diffusion of LED7.Its top pcb board 10 presents the polygonized structure of rule due to according to the structure fabrication of radiator 6 end faces, in order to ensure its light diffusion evenly, has used a plurality of half arc lampshade mix proportion top lampshades 11.

As shown in Fig. 2-4, described radiator 6 comprises a column structure, uniform radiating groove 63 on its lateral surface, and the outer surface of the relatively described radiator of described radiating groove 63 caves inward.Described pcb board 8 is set between adjacent radiating groove 63.Part between adjacent groove is symmetrical arranged two recesses 61 outwardly and two relative recesses 62.Described two relative recesses 62 are stretched in described pcb board 8 both sides, the fixing described pcb board 8 of described recess 62, the bending part 91 of described arc lampshade bar 11 stretches into respectively described two recesses 61 outwardly, and described LED lampshade 9 is fixed on described radiator 6.11, described radiator 6 and arc lampshade are fixed on lamp holder by fixed leg.This fixed leg can be made structure as shown in Figure 2 in the present embodiment, be respectively the first fixed leg 3 and the second fixed leg 5, the second fixed leg 5 has the recess with arc lampshade bar 1 and radiator end face form fit, be used for fixing radiator 6 and arc lampshade 11, be divided into two part making and also can be convenient for changing difform lampshade 9 and radiator 6.Described arc lampshade bar 9 one ends are fixed on the second fixed leg 5, and the other end and top lampshade 11 are connected to form lamp body.described power supply 2 is arranged in lamp holder 1, on described lamp holder 1, louvre 12 is set, power supply 2 independently is arranged in lamp holder 1 to be taken away power supply 2 heats by the louvre 12 in lamp holder 1, realize that in lamp holder 1 inside cross-ventilation improves radiating rate, radiator 6 can effectively be taken away the heat of top pcb board for the column structure of hollow, simultaneously also can realize cross-ventilation by the part of inner hollow, improve radiating effect, can certainly between the first fixed leg 3 and the second fixed leg 5, heat sink be set, can go out dissipation of heat rapidly by heat sink, compare traditional LED lamp and only at lamp holder 1, the radiator structure better effects if is set at it, in addition because power supply 2 makes it separate with LED7 by the first fixed leg 3 with the second fixed leg 5, effectively isolate the heat between LED7 and power supply 2, make the LED7 heat can not affect power supply 2 work, in traditional LED lamp, LED lamp and power supply 2 all approach very much, to affect 2 life-spans of power supply for the LED lamp that works long hours.

Say on the whole, separately pcb board 8 is carried out the diffusion of light by arc lampshade bar 9, improve the light uniformity.Reduce blackening.Can increase bar shaped pcb board 8 according to the needs of oneself, very convenient in the time of use, and maintain easily, because arc lampshade bar 9 and top lampshade 11 all are fixed, only need to open lampshade 9 and get final product when the parts of inside need to be changed.

The above is not that this novel technical scope is imposed any restrictions, and all any modification, equivalent variations and modifications of above embodiment being done according to the utility model technical spirit all still belong in the scope of this novel technical scheme.
