The specific embodiment

The specific embodiment that the utility model adopts will and attachedly be graphic and be further described by following embodiment.

Consult Fig. 1 to shown in Figure 4, Fig. 1 is the stereogram that shows the LED bulb of the first embodiment of the present utility model, Fig. 2 is the explosive view that shows the LED bulb of the first embodiment of the present utility model, Fig. 3 is the profile that shows the LED bulb of the first embodiment of the present utility model, and Fig. 4 is the irradiation angle schematic diagram that shows the LED bulb of the first embodiment of the present utility model.The LED bulb 100 of the first embodiment of the present utility model comprises a lamp body 1, a LED module 2, a lamp holder 3, reaches a lampshade 4.

Lamp body 1 is the hollow housing of a circular tower cylindricality in the present embodiment, and is one-body molded the making of material (example, metal) of heat conduction and good heat dissipation, and certainly, the utility model is not limited to this, and lamp body can be also the cylinder of square column housing or other various shapes.Lamp body 1 has a supporting part 11, a carrier 12, a side extension 13 and a heat dissipating layer 14.The epimere of lamp body 1 is supporting part 11, and supporting part 11 is cylindrical in the present embodiment, and has loading end 111 and a side loading end 112 on one.Upper loading end 111 is the upper surface of supporting part 11, and supporting part 11 forms a storage tank 113 to install LED module 2 in the downward indent of loading end 111, and loading end 111 has a through hole 110, passes for an electric wire L who is connected between LED module 2 and lamp holder 3.Side loading end 112 from the side of upper loading end 111 and one to downward-extension, and the footpath of supporting part 11 in side loading end 112 along cylinder yearned for and inside contracted and form a stair-stepping accommodating rank section 114 in the side of supporting part 1 to install LED module 2.By storage tank 113 for indent and accommodating rank section 114 structure for inside contracting, and dwindle the volume of supporting part 11, make the volume of LED bulb 100 integral body dwindle thereupon.

Carrier 12 have one from side loading end 112 and one to the surface of downward-extension flaring, form the stage casing part of lamp body 1, in the present embodiment, carrier 12 is the conical flask shape.By the flaring surface of carrier 12 to downward-extension, make lamp body 1 larger with the contact area of air, and improving radiating effect.Moreover, because carrier 12 is up-narrow and down-wide, so the supporting part 11 of top is done smallerly, do not emit beam and can not keep off the LED module that is arranged at side loading end 112, then its light that sends penetrates along the surface of flaring, and reaches the luminous effect of wide-angle.

Side extension 13 from carrier 12 and one to downward-extension, form the hypomere part of lamp body 1.Side extension 13 has one sheathed 131 and a junction 132.Be used for fixing lampshade 4 for sheathed 131, and connecting portion 132 is used for connecting lamp holder 3.Connecting portion 132 is a connecting thread in the present embodiment, and lamp holder 3 has the engage threads 31 of a corresponding connecting thread, makes lamp body 1 engage with lamp holder 3 to fix and connecting thread and the mutual spiral shell of engage threads 31 are solid, and is certain, also can be by modes such as engaging, bondings.

Heat dissipating layer 14 is a kind of heat sink material coating in the present embodiment, coat the surface of lamp body 1, certainly, also can coat the hollow interior surface (not shown) of lamp body 1, improving heat heat radiation with lamp body 1 to airborne efficient, and effectively reduce the temperature of LED bulb 100.

LED module 2 comprises lamp plate 21 and a soft lamp plate 22 on one.Upper lamp plate 21 comprises more than one LED 211, is in the present embodiment discoideus and is arranged at the storage tank 113 of loading end 111, make lamp plate 21 in the lighting angle θ 1 of upper loading end 111 near 180 degree.Soft lamp plate 22 is arranged at the accommodating rank section 114 of side loading end 112 in the present embodiment circlewise, and soft lamp plate 22 comprises the LED 221 of several ring-like arrangements, makes luminous azimuth angle

Reach 360 degree and spend near 180 in the lighting angle θ 2 of side loading end 112.From the above, by the stack of the lighting angle of upper lamp plate 21 and soft lamp plate 22, make more than the total lighting angle of LED module 2 reaches all-round light 330 degree.

Lampshade 4 is the transparent lamp shade of a spherical shell shape in the present embodiment, makes for high stray mist surface glass, makes the LED module light source irradiation diffuse into submissiveer light after lampshade.Certainly, the utility model is not limited to this, and it is spherical that lampshade 4 also can right and wrong, and such as rugby shape, taper shape or the design etc. of hollow hole is arranged, and material can be also clear glass etc., as long as can printing opacity.Lampshade 4 has an opening 41, and opening 41 is sheathed is fixed in sheathed 131 and make lampshade 4 cover caps to supporting part 11 and carrier 12, even LED module 2 is positioned at lampshade 4.The ora terminalis of the opening 41 of lampshade 4 to the maximum angle of the centre of luminescence of lampshade 4 is 30 degree, the LED 221 that the centre of luminescence 42 is defined as on soft lamp plate 22 extends the confluce in the top of down luminous edge boundary line P, and the folded angle θ 3 of the centre of luminescence 42 and the opposite two side edge 411 of opening 41 is 30 and spends (as shown in Figure 4).By this, make the scope that covers of lampshade 4 reach 330 degree, luminous with all-round light 330 degree of corresponding LED module 2.In the present embodiment, sheathed 131 is that the mode that adopts engage is fixedly connected with lampshade 4, and certainly, the utility model is not limited to this, and also spiral shell is consolidated or the mode such as bonding.

According to above-mentioned technological means, the LED bulb 100 of the present embodiment has the all-round light 330 luminous effects of degree, and its range of exposures angle is larger, makes LED bulb 100 can be applicable to more kinds of occasions.Moreover, the heat of LED module 2 conducts to lamp body 1 by the mode with loading end 111 and the 112 plane thermo-contacts of side loading end, then via the promptly heat conduction of integrated lamp body 1, heat is on average conducted to whole lamp body 1, the surface that is relending lamp body 1 inner surface and carrier 12 flarings for hollow housing has increases the surface area that contacts with air, and the heat dissipating layer 14 that lamp body 1 surface has is accelerated the exchange rate between lamp body 1 and air, thereby heat is promptly dispelled the heat to air.By this, make radiating effect better, and effectively reduce the temperature of LED module, and extend its service life.

Consult shown in Figure 5ly, it is the explosive view that shows the LED bulb of the second embodiment of the present utility model.The structure of the LED bulb 100a of these two embodiment and the LED bulb 100 of the first embodiment is roughly the same, its difference is that the lamp body 1a side of LED bulb 100a has more several radiating fins 15, radiating fin 15 has from the outward extending heat radiation lamellar body 151 of the side one of the carrier 12a of lamp body 1a, increase the surface area that lamp body 1a contacts with air, make radiating effect better.In the present embodiment, the alternate spacer ring of every a slice radiating fin 15 comes the side of carrier 12a, the flaring surface of its form fit carrier 12a, for outwards and from top to bottom tilting to extend, thus, the illumination that makes LED module 2 send is mapped to the bottommost of light shield 4 to reach the all-round light 330 luminous effects of degree.Certainly, the utility model is not limited to this, and radiating fin also can be arranged on the side extension, or radiating fin more can be coated with a heat dissipating layer help the heat radiation.Other is identical with the first embodiment, repeats no more.

Above narration be only preferred embodiment explanation of the present utility model, allly is skillful in this skill person when can do according to above-mentioned explanation other all improvement, however these changes still belong to creation spirit of the present utility model and the scope of the claims of defining in.
