Description

A kind of radiator structure of LEDbulb lamp
Technical field
The utility model relates to LED lamp assembling field, particularly relates to radiator structure and the radiating mode of LED lamp.
Background technology
LED is a kind of solid-state semiconductor devices, and he directly can convert electrical energy into luminous energy, and the advantages such as it has, and volume is little, energy consumption is low, the life-span is long, the high and low heat of brightness, environmental protection, are described as forth generation light source.Although LED is cold light source, as long as there is the flowing of electric current to produce heat, therefore how efficiently heat radiation is a very important problem for LED lamp.
At present in LEDbulb lamp, contour structures that is that mainly continue to use or conventional incandescent; Relevant criterion requires that LEDbulb lamp spatially accomplishes 360 all-round light at Light distribation simultaneously.But due to the radiating requirements of LED, usually need to realize by metal heat sink object of dispelling the heat, the current research emphasis for LEDbulb lamp heat radiation still concentrates on the change of radiator profile, and the heat making LED inside produce can be delivered in air fast.If realize all-round Light distribation, will radiator be reduced, light just can be made also to reach Light distribation up to specification at lamp socket rear.Meanwhile, under LED industry makes great efforts the overall background of reduction LEDbulb lamp cost, metal heat sink but accounts for 30% of cost.Therefore, design a kind of novel, simple radiator structure or cooling system for LED luminous characteristics, vital effect is played for the control of LEDbulb lamp cost and the raising of luminosity and efficiency.
Utility model content
The utility model provides a kind of heat sinking mode for LEDbulb lamp and radiator structure, produces the circulation of heat, thus reach the object of LED lamp high efficiency and heat radiation when driving LED luminous by the natural flow of air; The heat radiation of LED lamp is made to become more simple and practical by rational aerodynamic structures design.Disclosed in the utility model, technical scheme is specially:
A kind of radiator structure of LEDbulb lamp, it is characterized in that, described radiator structure comprises bulb lamp lampshade (1), LED lamp bead (2), louvre (3) on heat-conducting seat (5), metallic support (4), louvre (6) on described metallic support (4), described lampshade (1) forms by the louvre (3) on the louvre (6) on lamp pearl metallic support (4) and described heat-conducting seat (5) passage that air natural flows, air can be flowed along described metallic support (4), thus endlessly the heat that described LED lamp bead (2) sends is taken in extraneous air.
Further, the louvre (6) on described lamp pearl metallic support (4) includes but not limited to square, circular, pentalpha with the louvre (3) on described heat-conducting seat (5).
Further, the diameter of the louvre (3) on the louvre (6) on described lamp pearl metallic support (4) and described heat-conducting seat (5) is in 0.1-5mm.
Further, described lamp pearl metallic support (4) includes but not limited to metal material.
Further, described LED lamp bead (2) includes but not limited to 2835,5630,7020,3014.
Further, the insulating materials of described heat-conducting seat (5) includes but not limited to pottery, heat conduction plastic cement.
Further, anti-steam process is carried out to the lamp body of described LEDbulb lamp, improve the life-span under lamp body non-tight.
Further, described lamp pearl metallic support (4), as the circuit board of described LED lamp bead (2), adopts insulating materials and circuit to isolate, and drives integrated in the upper realizing circuit connection of described lamp pearl metallic support (4) and IC.
Technical scheme disclosed in the utility model has following technique effect:
By the heat radiation of air natural flowing completely, eliminate the metal heat sink part that LED lamp generally adopts, thus greatly reduce die sinking and the cost of manufacture of metal heat sink, and make process simplification.Also possibility is become for LEDbulb lamp realizes all-round light luminescence specific to incandescent lamp better.For meeting the demand of different size, we only need change circuit and connect and distribution on metallic support, the problem such as decrease the production equipment in traditional bulb lamp process in different aluminum substrate processing technology, SMT paster technique, packaging technology equally correlated process, the wasting of resources that processing manpower causes, production efficiency are low.By this, this support module effectively shortens technological process, reduces different size module group assembling cost, improves production efficiency, compares can reduce costs 60% with existing bulb lamp.

Detailed description of the invention
In order to understand the technical solution of the utility model better, be further elaborated below in conjunction with accompanying drawing.
As shown in Figure 1,2 and 3, the utility model provides a kind of radiating structure of LEDbulb lamp, it comprises the bulb lamp lampshade 1 with the louvre 3 being convenient to air flowing, described lampshade 1 forms by louvre on lamp pearl metallic support 46 and the louvre 3 on the heat-conducting seat 5 of LED bulb the effective way that air natural flows, air can be flowed along lamp pearl support 4, thus endlessly the heat that LED lamp bead 2 sends is taken in extraneous air.Adopt lamp pearl metallic support 4 one aspect can add the area of dissipation of headlight pearl, the heat-conducting seat 5 being simultaneously fixed in LED lamp bead 2 makes the heat of lamp pearl 2 can be delivered on heat-conducting seat 5 along metallic support 4, and then is dispersed in air.Thus make the LEDbulb lamp radiating effect not adopting metal heat sink also can reach cooling requirements, greatly reduce the cost of LEDbulb lamp.
Wherein, metallic support 4, as the circuit board of LED lamp bead 2, adopts insulating materials that metallic support internal circuit is isolated, thus realizing circuit connection and IC drive integrated on metallic support 4.
Metallic support 4, lampshade 1 and heat-conducting seat 5 realize difformity louvre (as square, circular, pentalpha etc.), be ensure Electrical Safety, the diameter of these louvres is within the scope of 0.1-5mm.Meanwhile, this is also conducive to the release of organic volatile in lamp body and the halogen element such as bromine, chlorine, effectively solves the yellow of LED component in seal, the light decay problem that melanism causes.LED lamp bead support includes but not limited to metal material.LED lamp bead size design is flexible, changeable, includes but not limited to 2835,5630,7020,3014.The insulating materials of heat-conducting seat includes but not limited to pottery, heat conduction plastic cement etc.
Also should carry out anti-steam process to LED lamp, and then improve the life-span of LEDbulb lamp under non-tight.Meanwhile, in different angles, highly, the LED monomer of varying number can be designed, meet luminous flux design requirement.
