Abstract
The utility model relates to the technical field of lampshades, in particular to an LED (light emitting diode) heat radiating lampshade. The LED heat radiating lampshade comprises a lampshade body; a plurality of radiating holes are formed in the round wall of the lampshade body; inner fins inclined to the inner cavity of the lampshade body are arranged at the top ends of the radiating holes; a plurality of top radiating holes are uniformly circumferentially formed in the top of the lampshade body. When the LED heat radiating lampshade is used, the radiating fins are designed to be fin-shaped, an LED generates massive heat in the lighting process, the heat is very fast dissipated due to the principle of vertical ascent of hot air and descent of cold air, and the heat radiating aim is achieved, so the service life of the LED lamp is effectively prolonged. The LED heat radiating lampshade has the advantages of simple structure, reasonable design, low manufacturing cost and the like.
Description
Technical field
The utility model relates to lampshade industry technology field, particularly a kind of LED heat radiation lampshade.
Background technology
LED lampshade is the one of LED accessory, be for better by light-ray condensing, make light more concentrated softer, avoid the direct projection of LED light dazzling.LED can produce a large amount of heat in luminescence process, if these heat can not distribute in time, light affect the work of electric elements, reduces its service life or it is damaged, and heavy breaking out of fire endangers people's lives and properties.For this reason, just done in the industry many significant explorations, a lot of producers are designed with various heat radiation lampshades, but the design of these lampshades is unreasonable, radiating effect is not high, has affected the life-span of LED, endanger people's the security of the lives and property, restricted the security reliability of LED.
Therefore be necessary the structure of existing LED heat radiation lampshade to carry out technological innovation further.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of LED heat radiation lampshade simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of LED heat radiation lampshade described in the utility model, comprise lampshade, on the round wall of described lampshade, be provided with several louvres, the top of described louvre is provided with to the interior fin of cavity dumping in lampshade, and described lampshade top is even circumferential and is provided with several top louvres.
Further, the angle between described interior fin and lampshade axial line is 18～24 degree.
Further, the quantity of described top louvre is eight.
Adopt after said structure, the utility model beneficial effect is: a kind of LED heat radiation lampshade described in the utility model, comprise lampshade, on the round wall of described lampshade, be provided with several louvres, the top of described louvre is provided with to the interior fin of cavity dumping in lampshade, and described lampshade top is even circumferential and is provided with several top louvres.In the time using the utility model, by fin shape in heat sink design is become, LED can produce a large amount of heat in luminescence process, these hot gas vertical lifting, the convective principles that cold air declines, dispels the heat out by heat as quick as thought, reach the object of heat radiation, thereby effectively extend the service life of LED lamp.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.

Fig. 1 is stereogram of the present utility model;
Fig. 2 is top view of the present utility model;
Description of reference numerals:
1, louvre; 2, interior fin; 3, top louvre.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1-2, a kind of LED heat radiation lampshade described in the utility model, comprise lampshade 1, on the round wall of described lampshade 1, be provided with several louvres 1, the top of described louvre 1 is provided with to the interior fin 2 of lampshade 1 interior cavity dumping, and described lampshade 1 top is even circumferential and is provided with several top louvres 3.The size of louvre 3 will be determined according to the heat dissipation capacity of LED lamp, and louvre 3 perforates are excessive to be made the undercapacity of lampshade 1 and produces distortion, and louvre 3 perforates are too little, dispel the heat bad, affects LED lamp service life.
As a kind of optimal way of the present utility model, the angle between described interior fin 2 and lampshade 1 axial line is 18～24 degree.
As a kind of optimal way of the present utility model, the quantity of described top louvre 3 is eight.
In the time using the utility model, by fin shape in heat sink design is become, LED can produce a large amount of heat in luminescence process, these hot gas vertical lifting, the convective principles that cold air declines, dispels the heat out by heat as quick as thought, reach the object of heat radiation, thereby effectively extend the service life of LED lamp.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
