Ring the service life of LED light.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of high-power LED bulbs, by being arranged in the bottom of driving
Multiple air holes are fixed on the plastic cement column of fan protrusion, since plastic cement column has certain altitude, such fan and driving
Between be maintained for certain gap, when fan work, since airflow direction blows to LED aluminum base plate, radiate to LED aluminum base plate
While drive external cold air to radiate driving, formed inside and outside hot and cold air convection current and displacement.On lamp on lid
Multiple ventilation holes are provided with, the heat dissipation effect of driving is further improved.
In order to realize that technical purpose of the invention, the present invention adopt the following technical scheme that.
A kind of high-power LED bulb, including lamp upper cover, the lamp cap positioned at lamp upper cover upper end, fan, radiator, LED aluminium
Substrate, aluminium retainer plate and lampshade, the LED aluminum base plate are fixed on the lower end surface of radiator, and the aluminium retainer plate is connected and fixed
Radiator and lampshade, wherein also setting up in the end face of the fan, there are two the plastic cement columns of protrusion, are fixed on the plastic cement column
Driving, the bottom of the driving is provided with multiple air holes.
Further, multiple ventilation holes are provided on lid on the lamp.
Further, the wind direction of the fan blows to LED aluminum base plate.
Further, the open slot of heat dissipation ventilation is equipped with close to one end of LED aluminum base plate in the radiator.
Further, fluted by the setting of one end of low beam upper cover in the radiator, the fan is installed in groove.
Further, the shape of the cooling fin of the radiator is fin-like.
Further, fixation is connected through a screw thread between the lamp cap and lamp upper cover.
The invention has the advantages that: the present invention provides a kind of high-power LED bulbs, by the bottom of driving
Multiple air holes are arranged in portion, are fixed on the plastic cement column of fan protrusion, since plastic cement column has certain altitude, such fan
Certain gap is maintained between driving, when fan work, since airflow direction blows to LED aluminum base plate, to LED aluminium base
Cold air outside driving while plate radiates enters from the gap between the air hole and plastic cement column of driving bottom, inside and outside formation
The convection current and displacement of hot and cold air, radiate to driving.Multiple ventilation holes are provided on lid on lamp, form lamp upper cover → drive
Dynamic → fan → radiator → LED aluminum base plate → open slot cross-ventilation, further improves the integral heat sink of LEDbulb lamp
Effect improves the service life of LED lamp.

Specific embodiment
In order to which the technical problems, technical solutions and beneficial effects solved by the present invention is more clearly understood, below with reference to
Accompanying drawings and embodiments, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used
To explain the present invention, the present invention is not limited.
Shown in referring to FIG. 1, FIG. 2 and FIG. 3, the present invention provides a kind of high-power LED bulbs, including lamp upper cover 2, are located at
The lamp cap 1 of 2 upper end of lamp upper cover, fan 4, radiator 5, LED aluminum base plate 6, aluminium retainer plate 7 and lampshade 8.It is set in the lamp upper cover 2
Multiple ventilation holes 21 are equipped with, lamp upper cover 2 and lamp cap 1 are connected through a screw thread fixation.There are two protrusions for the end face setting of the fan 4
Plastic cement column 41, be fixed with driving 3 on plastic cement column 41,3 bottom driven to be provided with multiple air holes 31.The radiator 5 leans on
One end of nearly LED aluminum base plate 6 is equipped with the open slot 51 of heat dissipation ventilation, and the cooling fin of radiator 5 is fin-like.The LED aluminium base
