The heat dissipation LED lampshade comprises a lampshade shell, a lampshade inner cavity, a graphite heat dissipation layer, a heat dissipation fin body and a fixing rod, wherein air holes are formed in the top of the lampshade shell; the graphite heat dissipation layer is arranged at the top of the lampshade inner cavity; the heat dissipation fin body is arranged at the bottom of the graphite heat dissipation layer; the heat dissipation fin body comprises a heat dissipation fin, a through hole and a heat insulation metal sheet; the heat dissipation fin penetrates through an inner cavity of the heat insulation metal sheet; the through hole is formed in the surface of the heat insulation metal sheet; the fixing rod is connected with the heat insulation metal sheet via the through hole; a plastic baffle is arranged at the bottom of the fixing rod; a lamp bead is arranged at the bottom of the plastic baffle. According to the heat dissipation LED lampshade, the air holes are formed in the lampshade shell, so that the air ventilation speed is accelerated; the heat is introduced into the graphite heat dissipation layer by the heat dissipation fin, so that the lamp bead keeps a certain temperature; the service life of the lamp bead is prolonged; the lamp bead is located at the middle of the metal sheet, so that the light is not blocked.

Description

A kind of cooling LED lampshade
Technical field
The present invention relates to Hardware and Lamps technical field, be specially a kind of cooling LED lampshade.
Background technology
LED is as a kind of energy-saving bulb, and not only power consumption is low, good illumination effect, and owing to its colour temperature is relatively low, what send is white light, human eye is not had very big stimulation, is therefore extensively used by people, but, LED is to be fixed in lamp housing inner chamber by multiple lamp bead, owing to lamp bead is densely distributed, lamp housing is closed, atmosphere draught-free, cause that the radiating effect of lamp bead is excessively poor, therefore just shorten its service life.
Summary of the invention
It is an object of the invention to provide a kind of cooling LED lampshade, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of cooling LED lampshade, including lampshade shell, lampshade inner chamber, graphite radiating layer, heat sink body and fixing bar, the top of described lampshade shell is provided with air vent, the top of described lampshade inner chamber is provided with graphite radiating layer, the bottom of described graphite radiating layer is provided with heat sink body, described heat sink body is by radiating fin, perforation, form with heat insulating metal sheet, the inner chamber of described heat insulating metal sheet runs through radiating fin, the surface of heat insulating metal sheet is provided with perforation, described fixing bar is connected with heat insulating metal sheet by boring a hole, the bottom of fixing bar is provided with plastic dam, the bottom of described plastic dam is provided with lamp bead.
Preferably, the inner side of described lampshade shell is provided with fixture block.
Preferably, at least provided with two perforation on described heat insulating metal sheet, and perforation and fixing bar suitable.
Preferably, described heat sink body and lamp bead symmetrically arrange.
Preferably, described lampshade shell is circular arc.
Compared with prior art; the invention has the beneficial effects as follows: this cooling LED lampshade; lampshade shell is provided with air vent so that it is the speed of air circulation is more accelerated, and by radiating fin, heat imports to graphite radiating layer; make the temperature that the maintenance of its lamp bead is certain; extend the service life of lamp bead, and lamp bead is positioned at the centre of heat sink body, therefore without hindering to light; it is set to arc-shaped structure by lampshade shell, all lamp bead is played when it being collided and extrudes good protected effect.
Accompanying drawing explanation
Fig. 1 is present configuration front schematic view；
Fig. 2 is present configuration partial schematic diagram；
Fig. 3 is present configuration partial schematic diagram.
In figure: 1 lampshade shell, 2 air vents, 3 fixture blocks, 4 lampshade inner chambers, 5 graphite radiating layers, 6 lamp bead, 7 plastic dam, 8 heat sink body, 81 radiating fins, 82 perforation, 83 heat insulating metal sheets, 9 fixing bars.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
nullRefer to Fig. 1-3，The present invention provides a kind of technical scheme: a kind of cooling LED lampshade，Including lampshade shell 1、Lampshade inner chamber 4、Graphite radiating layer 5、Heat sink body 8 and fixing bar 9，The inner side of lampshade shell 1 is provided with fixture block 3，Certain fixing supporting role is played in its installation，Lampshade shell 1 is in circular arc，All lamp bead 6 is played good protected effect when it being collided and extrudes，The top of lampshade shell 1 is provided with air vent 2，Lampshade shell 1 is provided with air vent 2，The speed that its air circulates is made more to accelerate，The top of lampshade inner chamber 4 is provided with graphite radiating layer 5，The bottom of graphite radiating layer 5 is provided with heat sink body 8，Heat sink body 8 is by radiating fin 81、Perforation 82、Form with heat insulating metal sheet 83，The inner chamber of heat insulating metal sheet 83 runs through radiating fin 81，By radiating fin 81, heat imported to graphite radiating layer 5，Its lamp bead 6 is made to keep certain temperature，Extend the service life of lamp bead 6，The surface of heat insulating metal sheet 83 bores a hole 82 at least provided with two，And perforation 82 is suitable with fixing bar 9，Make fixing bar 9 by 82 fixing cooling fins main bodys 8 of boring a hole，Fixing bar 9 is connected with heat insulating metal sheet 83 by perforation 82，The bottom of fixing bar 9 is provided with plastic dam 7，The bottom of plastic dam 7 is provided with lamp bead 6，Heat sink body 8 and lamp bead 6 symmetrically arrange，And lamp bead 6 is positioned at the centre of heat sink body 8，Therefore without hindering to light.
Operation principle: during use, lamp bead 6 a period of time will generate heat, now, heat is imported by the radiating fin 81 being positioned at lamp bead 6 both sides, owing to the other end of radiating fin 81 inserts in graphite radiating layer 5, therefore being passed by lasting for heat, lampshade shell 1 is provided with vent 2, make its air passage rates very fast, so that heat distributes from vent 2 through graphite radiating layer 5.
