As preferably, described lamp body comprises curved surface openend and screw thread closing end, described curved surface openend and screw thread closing end are fixedly linked, described lamp holder is threaded with screw thread closing end, described power drives is located at the inside of screw thread closing end, described light-guiding pillar is fixedly connected with by the inwall of bolt with curved surface openend, and the openend of described diffuser is fixedly connected with curved surface openend.
As preferably, described diffuser is hemispherical, and the sphere diameter of described diffuser is greater than the height of light-guiding pillar.
As preferably, described power drives is connected with lamp pearl by wiring.
The beneficial effects of the utility model: compared with prior art, a kind of LED bulb with light-guiding pillar that the utility model provides, structure is simple, processing is convenient, and pattern is attractive in appearance, and lighting angle reaches 270 ° ~ 360 °, and the good result of uniformly light-emitting irradiation can be reached in use, meanwhile, also there is anti-dazzle effect, thus be beneficial to the combination property and the market competitiveness that improve LED bulb.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the exploded perspective figure of embodiment of the present utility model.
[detailed description of the invention]
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by accompanying drawing and embodiment, the utility model is further elaborated.But should be appreciated that, specific embodiment described herein, only in order to explain the utility model, is not limited to scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
Consult Fig. 1, first embodiment of the present utility model provides a kind of LED bulb with light-guiding pillar, comprise lamp holder 1, lamp body 2, power drives 3, lamp pearl 4, light-guiding pillar 5 and diffuser 6, lamp holder 1 is threaded with lamp body 2, it is inner that power drives 3 is located at lamp body 2, lamp pearl 4 and power drives 3 are electrically connected, and light-guiding pillar 5 installs the outside in lamp pearl 4, is gathered by the light that lamp pearl 4 sends.Light-guiding pillar 5 is fixedly connected with lamp body 2 by bolt 7, lamp pearl 4, light-guiding pillar 5 are all located at the inside of diffuser 6, light-guiding pillar 5 is in the cone of up-small and down-big two open ends, the diameter of one end that light-guiding pillar 5 is fixedly connected with lamp body 2 is greater than the diameter that light-guiding pillar 5 stretches into the other end of diffuser 6, and the openend of diffuser 6 is fixedly connected with lamp body 2.
Embodiment of the present utility model, owing to adopting light-guiding pillar 5 luminous, therefore under the effect of scattered light, its lighting angle can be extended to more than 270 ° or 270 degree.Also avoid divergence of beam simultaneously, the possibility of dazzle is reduced, improve the result of use of LED bulb.Wherein, due to the special shape of light-guiding pillar 5, light is penetrated from one end of osculum, and then form the effect of center luminescence as flame, not only increase the brightness of LED bulb, but also the light that LED bulb is sent is more natural, improves the result of use of LED bulb.
Particularly, lamp body 2 comprises curved surface openend 21 and screw thread closing end 22, curved surface openend 21 and screw thread closing end 22 are fixedly linked, lamp holder 1 is threaded with screw thread closing end 22, power drives 3 is located at the inside of screw thread closing end 22, light-guiding pillar 4 is fixedly connected with by the inwall of bolt 7 with curved surface openend 21, and the openend of diffuser 6 is fixedly connected with curved surface openend 21.
In embodiment of the present utility model, the curved surface openend 21 of lamp body 2 is the cone of up-small and down-big two open ends, and the osculum of bottom is connected with screw thread closing end 22, and the large mouth on top is abducent horn-like.The lamp body 2 of this kind of structure, can not only be connected lamp holder 1 with diffuser 5, but also can play the effect of heat radiation, namely makes the radiator structure in existing LED bulb to omit, simplifies the structure of LED bulb, improves the result of use of LED bulb.Certainly, in order to improve the radiating effect of lamp body 2 further, some louvres (attached not shown) can be offered as required on curved surface openend 21.
Wherein, curved surface openend 21 adopts heat proof material PC (Polycarbonate, Merlon), and screw thread closing end 22 adopts metallic material of aluminum.Compared with the structure of existing bulk metal material, the separation of bi-material makes the radiating effect of lamp body 2 improve, also more environmental protection, thus on the basis of result of use not affecting LED bulb, can cut down finished cost.
Further, diffuser 6 is in hemispherical, and the sphere diameter of diffuser 6 is greater than the height of light-guiding pillar 5.The utility model adopts hemispheric diffuser 6, makes LED bulb profile mellow and full, more lovely, is particularly useful for the Condom such as bedroom, dining room, can increase warm atmosphere.
After lamp holder 1 is communicated with household AC power, AC rectification can be that direct current is so that lamp pearl 4 works by power drives 3, the light that lamp pearl 4 sends is diffused into the inside of light-guiding pillar 5, then light-guiding pillar 5 is assembled gathering, and all illumination is mapped to all angles of whole diffuser 6 inside, comprises the part not having light source of being blocked by light-guiding pillar 5.
In above-mentioned two embodiments, diffuser 6 can be transparent glass, also can be suitable carry out special process according to user demand, such as set up frosted layer, or surface coating paint outside.
Meanwhile, according to color, the isoparametric difference of brightness of LED bulb used, the light-guiding pillar 5 of different colours and size can be produced, to meet different environment and the demand of client.Corresponding particular design can certainly be made to power drives 3, change of the change of such as LED look district, brightness and the change of mounting means, input voltage condition etc. according to the particular/special requirement of client.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection domain of the present utility model.
