The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, with the following Examples a kind of LED bulb of the present utility model is further described.
A kind of LED bulb comprises lamp body 1, pedestal 2 and lamp holder 3, and lamp body 1 is made of machine plate 11, heat abstractor 12, led chip 13, graphite linings.Led chip 13 is installed in machine plate 11 surfaces, heat abstractor 12 is connected with machine plate 11, and heat abstractor 12 is arranged at the another side of machine plate 11, between machine plate 11 and heat abstractor 12 graphite linings is set also, and led chip 13 tops can also be according to using needs that lens devices is set.Machine plate 11 is set to ramp structure, machine plate 11 comprises the handset plate more than two or two that is connected, because heat abstractor 12 is connected with machine plate 11, therefore, the face that heat abstractor 12 is connected with machine plate 11 correspondingly also is set to ramp structure, and the face that heat abstractor 12 is connected with machine plate 11 also comprises the planar structure more than two or two.The design of machine plate 11 ramp structures is in order to make the led chip 13 that is installed on the machine plate 11 have the broad effect of illumination.The ramp structure of machine plate 11 designs, and can increase the irradiated area of light, makes the service efficiency of light higher.Because the range of exposures of the utility model led light source has wide loosing, thereby has overcome in the prior art led light source parallel projection, the narrow defective of scope.Among this embodiment, machine plate 11 is set to 3, angle between adjacent two blocks of machine plates 11 is the obtuse angle setting, make and form three-dimensional structure between three blocks of handset plates 11, the machine plate that is positioned at both sides has ramp structure, so led chip 13 integral body that are arranged on machine plate 11 also have three-dimensional structure, the structure by machine plate 11 is arranged so that the range of exposures of led light source has wideer diffusing characteristics.The face that is connected with machine plate 11 of heat abstractor 12 correspondingly is set to three planes simultaneously, and the angle between adjacent two planes is the obtuse angle, strengthens heat radiation with the respective outer side edges with this machine plate.Machine plate 11 is set to three-dimensional structure, both can reach the purpose that realizes led light source range of exposures broadness, processes simple and convenient simultaneously.
Heat abstractor 12 can be the formed heat abstractor of aluminium alloy extruded moulding, has the characteristics of good heat dissipation effect, increases graphite linings and further strengthen its radiating effect between heat abstractor 12 and machine plate 11.Utilize these heat radiation materials of heat abstractor 12 and graphite linings to increase the radiating effect of this LED bulb, slow down light decay and carbon dioxide, not only can improve the brightness of bulb and can also play the effect that prolongs bulb service life because of generating heat and being produced.
Heat abstractor 12 is provided with link 121, and this link 121 is connected with pedestal 2.Link 121 is set to groove structure, and link 121 also is provided with first through hole 122.Pedestal 2 comprises and connects nose 22 and matrix 21, connects nose 22 and has helicitic texture, and connect nose 22 and also be provided with second through hole 221, and this second through hole 221 matches with first through hole 122.The link 121 of heat abstractor 12 be connected nose 22 and be threaded, connecting nose 22 can arbitrarily rotate by 360 degree in the groove of link 121, to adjust the lamp body setting angle, cooperate screw 201 that first through hole 122 is fixedlyed connected with corresponding second through hole 221 then, thereby realize fixedlying connected between pedestal 2 and the lamp body 1.
The matrix 21 of pedestal 2 is provided with the louvre 23 of radius 0.8~1.2mm.Louvre 23 is used to increase the radiating effect in the pedestal 2 on the one hand, simultaneously because this louvre 23 is smaller, can avoid because mosquito etc. flies into pedestal 2, and cause mosquito etc. to die from bulb inside, thereby avoid owing to long-time accumulations in bulb such as mosquito influence heat radiation and influence defective such as bulb life.
In order to be applicable to various light fixtures on the market, the lamp holder 3 of this bulb can be designed as the structure that can change and be used with multiple model light fixture, as can be the structure that E27, E26 and E40 etc. exchange, so that this LED bulb has the applicability of broadness.
When changing traditional light source, a kind of LED bulb that adopts the utility model to provide does not need to change whole light fixture, only needs to change this LED bulb and gets final product, and can save cost, saves time.And LED bulb of the present utility model is installed very simply, and only needing this LED bulb directly is spirally connected gets final product, and therefore, assembles simple and convenient.
In sum, a kind of LED bulb of the present utility model have that illumination zone is wide, good heat dissipation effect, convenient, the easy-to-install characteristics of replacing.
Should be noted that at last; above embodiment is only in order to the explanation the technical solution of the utility model but not to the restriction of the utility model protection domain; although the utility model has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
