Abstract
The utility model discloses an LED lamp bulb which is good in heat dissipation effect and can replace a common incandescent lamp bulb or a common energy saving lamp. The LED lamp bulb comprises a lamp holder and at least one LED beads arranged on the lamp holder, and a lampshade is arranged on the lamp holder. The LED lamp bulb is characterized in that the lamp holder comprises a mounting portion made of metal and a lamp cap, a plurality of annular heat dissipation sheets are arranged on the periphery of the mounting portion, a through hole is formed in the middle of the mounting portion, a mounting step is arranged on the upper surface of the mounting portion, a circuit board is adhered to the mounting step through heat conduction glue, a guide wire is arranged between the circuit board and the lamp cap, a circular blocking edge is arranged on the outer edge of the upper surface of the topmost annular heat dissipation sheet, and the bottom of the lampshade is clamped in the blocking edge.
Description
Technical field
The utility model relates to a kind of LED bulb.
Background technology
In recent years, along with the maturation of LED lamp production technology, its application is also more and more extensive.LED light fixture has the not available advantage of many conventional lamp: 1.LED Lantern Festival electricity is up to more than 80%, and it is more than 10 times that the life-span is ordinary lamps.2.LED light fixture can not produce noise, is suitable for the place of library, office and so on.3. what traditional fluorescent lamp used is alternating current, so can produce the stroboscopic of 100-120 time each second.LED light fixture is that alternating current direct is switched through and is changed to direct current, can not produce scintillation, and protection eyes preserve from.4.LED light fixture can not produce ultraviolet ray, can as conventional lamp, not have a lot of mosquitoes to be centered around around lamp body, and therefore indoor meeting becomes, and clean hygiene is clean and tidy more.Based on above-mentioned various advantages, it is increasing that LED lamp substitutes the market demand of ordinary incandescent lamp or electricity-saving lamp, but LED lamp has relatively high expectations to radiating effect in use, and the words lamp pearly-lustre that dispels the heat bad declines and is exceedingly fast, and can greatly affect lamp life.
Utility model content
Technical problem to be solved in the utility model is: the LED bulb that a kind of good heat dissipation effect, replaceable ordinary incandescent lamp or electricity-saving lamp are provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of LED bulb, comprise lamp socket and be arranged at least one the LED lamp pearl on lamp socket, lamp socket is provided with lampshade, it is characterized in that: described lamp socket comprises installation portion and the lamp holder of metal material, installation portion periphery is provided with some annular fin, installation portion middle part is provided with through hole, installation portion upper surface is provided with installation step, on installation step, by heat-conducting glue, be pasted with circuit board, between circuit board and lamp holder, be provided with wire, the circular ring type heatsink upper surface outer ledge of top is provided with circular rib, described lampshade bottom is fastened in rib.
As a kind of preferred scheme, between described lampshade bottom and described rib, be provided with sealing ring.
As a kind of preferred scheme, described installation portion inwall is provided with contiguous block, contiguous block is provided with two through holes that are through to installation portion outer surface near place, bottom surface, described lamp holder upper surface is provided with two projections that coordinate with contiguous block, position corresponding to through hole on contiguous block on projection is provided with screwed hole, between lamp holder and installation portion, is connected by screw.
As a kind of preferred scheme, described lamp holder is lamp screw base.
As a kind of preferred scheme, described lampshade is the Transparent lamp shade that scribbles fluoresent coating.
The beneficial effects of the utility model are: this LED bulb, can direct mounted ordinary incandescent lamp or electricity-saving lamp owing to having adopted the contour structures identical with ordinary incandescent lamp and electricity-saving lamp.And because the installation portion periphery of metal material is provided with some annular fin, the heat of lamp pearl can effectively be distributed, thereby guarantee the service life of lamp pearl.
Owing to being provided with sealing ring between lampshade bottom and described rib, guaranteed the sealing between lampshade and lamp socket, can prevent that steam from entering lampshade internal influence light fixture performance.
Due between lamp holder and installation portion, by contiguous block, be connected easy for installation and sound construction with projection and screw.
