Abstract
The utility model relates to a heat dissipation and isolation structure of an LED (Light Emitting Diode) bulb lamp, belonging to the field of LED illumination. The heat dissipation and isolation structure of the LED bulb lamp consists of a lamp body and a heat sink, wherein the lamp shell consists of a lamp shell body; the lamp shell body is in the shape of a horn; multiple supporting ribs are arranged on the circumference of the lamp shell body in a spacing way; a part between each two adjacent supporting ribs of the lamp shell body is hollow; a stepped through hole is formed in the center part of the lamp shell body; and the heat sink is installed on the lower end of the through hole. With the adoption of the heat dissipation and isolation structure of the LED bulb lamp, the lamp shell body is made from a plastic material and adopts a hollow structure; therefore, the heat dissipation effect is effectively improved, the procedures are reduced, and meanwhile, the problems of procedure tediousness and affection on the working efficiency to a certain extent caused by the arrangement of an insulating layer between the lamp shell and an electric component in the prior art are solved; and meanwhile, the processing difficult is lowered and the service life of the LED bulb lamp is prolonged.
Description
Technical field
The utility model relates to a kind of LED bulb lamp heat radiation isolation structure, belongs to the LED lighting field.
Background technology
The LED lamp is a kind of semiconductor that electric energy conversion can be become visible light, and it has changed the luminous principle luminous with the electricity-saving lamp tricolor powder of incandescent lamp tungsten filament, and adopts electric field electricity-generating.LED have the life-span long, light efficiency is high, the characteristics of radiationless and low-power consumption, so within the quite long period of history, LED will be as the main flow of lighting source.
At present, most LED bulb lamp lamp housing is full aluminium foundry goods, for improving radiating effect, the surface of lamp housing is provided with radiating fin, and the heat that the lamp pearl produces in the course of work conducts to lamp housing by aluminium base, then distributes by radiating fin, so just necessarily requiring lamp housing is metallic article, cause the lamp housing high expensive, and then so that LED bulb lamp holistic cost is higher, affects it and popularize; And LED ball bubble must arrange insulating barrier between lamp housing and electric component (driving power) in assembling process, the purpose of isolating safely to reach lamp housing and electric component so that its operation is loaded down with trivial details, affects operating efficiency to a certain extent.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, but the Effective Raise radiating effect, reduce production costs low, and safe isolation effect is good, higher to solve existing LED bulb lamp holistic cost, affecting it popularizes, and assembly process is loaded down with trivial details, affects to a certain extent the LED bulb lamp heat radiation isolation structure of operating efficiency problem.
The utility model is to realize by the following technical solutions above-mentioned purpose:
A kind of LED bulb lamp heat radiation isolation structure, it is made of lamp housing and fin, it is characterized in that: lamp housing is made of the lamp housing body, the lamp housing body is megaphone-shaped, the interval shape is provided with a plurality of brace rods on the circumference of lamp housing body, is Openworks shape between per two brace rods of lamp housing body, is respectively arranged with louvre on each brace rod of lamp housing body, the centre of lamp housing body is provided with step-like through hole, and the through hole lower end is equipped with fin.
Described fin is circular, is the radial radiation tooth that is provided with on the circumference of fin, is symmetry shape on the inner hole wall of fin and is provided with the electric component slot.
The utility model beneficial effect compared with prior art is:
This LED bulb lamp shell is made by plastic material, adopt engraved structure, the heat that the lamp pearl produces in the course of work conducts to fin by aluminium base, then shed by the hollow out between the brace rod of lamp housing body, make its radiating effect be able to Effective Raise, reduced simultaneously and manufactured cost, and need not in process of production between lamp housing and electric component (driving), insulating barrier to be set, can reach good safety isolation purpose, reduced operation, avoided having now between lamp housing and electric component (driving) insulating barrier has been set, so that operation is loaded down with trivial details, affected to a certain extent the problem of operating efficiency.On the other hand, the utility model has reduced difficulty of processing, has improved the service life of LED bulb lamp.

Among the figure: 1, lamp housing body, 2, brace rod, 3, louvre, 4, through hole, 5, fin, 6, radiation tooth, 7, the electric component slot.
The specific embodiment
This LED bulb lamp heat radiation isolation structure is made of lamp housing and fin, lamp housing is made of lamp housing body 1, lamp housing body 1 is megaphone-shaped, the interval shape is provided with a plurality of brace rods 2 on the circumference of lamp housing body 1, be Openworks shape between per two brace rods 2 of lamp housing body 1, be respectively arranged with louvre 3 on each brace rod 2 of lamp housing body 1, the centre of lamp housing body 1 is provided with step-like through hole 4, and through hole 4 lower ends are equipped with fin 5.Fin 5 is circular, is the radial radiation tooth 6 that is provided with on the circumference of fin 5, is symmetry shape on the inner hole wall of fin 5 and is provided with electric component slot 7.
During assembling, electric component (driving) directly is assemblied in the through hole 4 of lamp housing body 1 by electric component slot 8, lamp holder is installed on lamp housing body 1 top, the aluminium base that the lamp pearl is installed is installed on the lamp housing body 1 of fin 5 belows, fin 5 fits tightly with aluminium base, then by diffuser aluminium base is covered to get final product.Lamp housing body 1 adopts the plastic material that reaches fire-protection rating to make, and need not between lamp housing body 1 and electric component (driving) insulating barrier to be set when therefore assembling, and can reach good safety isolation purpose.In the course of work, the heat that lamp pearl etc. produce conducts to fin 5 by aluminium base, is then shed by the hollow out between the brace rod 2 of lamp housing body 1, compares radiating effect than prior art and is able to Effective Raise.
