Background technology
In LED industry, when manufacturing LED fluorescent tube, the common method that light source aluminium base is fixed on radiation aluminium alloy shell is mostly adopted modes such as being screwed, applying heat conduction bonded adhesives, stickup bond plies at present.As adopted, be screwed, not only time-consuming during production, and also easily loosening, so just have potential safety hazard, moreover heat-conducting effect neither be ideal, because centre must exist the air gap, cause larger thermal contact resistance.As adopt coating heat-conducting cream etc., and the heat-conducting cream price of thermal conductivity factor is more expensive preferably on the one hand, and low thermal conductivity factor does not reach again good heat-conducting effect, and it is quite time-consuming applying on the other hand this cream.These shortcomings, have all limited applying of LED lighting engineering.
Summary of the invention
The present invention is in order to solve deficiency in this respect, provide a kind of new LED fluorescent tube light source board fixed form with and processing method is installed, by machinery, assemble, assemble so on the one hand fairly simple, can save production cost in a large number, reliability is high on the other hand, can improve heat conductivility again.
An object of the present patent application is to provide a kind of LED light source board fixing structure.
Specifically, LED light source board fixing structure of the present invention, comprise LED substrate and heat sink section bar, wherein, LED substrate comprises substrate and is arranged on the LED on substrate, heat sink section bar is the hollow columnar structures isometric with substrate, and a side is provided with the draw-in groove that holds substrate, and the dual-side of draw-in groove is respectively equipped with have a down dip in oblique domatic.
Further, described draw-in groove and substrate interference fit, the width of draw-in groove is less than the width of substrate, and such design is for substrate being embedded more closely and chimeric with heat sink section bar, reaches best radiating effect.
In machining and manufacture process, the mated condition of the above parts of two or two can be divided into be roughly slidably matched, many grades such as interference fits and tight fit, interference fit belongs to a kind of in what tight fit, that is to say that the diameter of axle (key is wide) that matches wants large what aperture (keyway), must adopt special tool(s) to push into, or utilize the characteristic of rising-heat contracting-cold, hole (keyway) heated, take advantage of borehole enlargement, be set to rapidly on axle, rear two parts of contraction to be cooled have just tightly fitted in one.Interference is how many, on processing drawing, is all described in detail.If meet some part, can not take heating, also axle (key) can be placed in dry ice coolingly, effect is the same.
Further, described substrate is aluminium base.
Same, described heat sink section bar is heat-dissipation aluminum sectional material.
Another object of the present patent application is to provide the installation processing method of said structure.
Specifically, described method comprises the steps:
1, get the light source aluminium base of LED fluorescent tube and both sides with slipping into domatic heat-dissipation aluminum sectional material, heat-dissipation aluminum sectional material wherein, the tolerance dimension of the tolerance dimension of aluminium base width and aluminium section bar two side width is applicable to interference fit device;
2, first one end of LED light source aluminium base is put into section groove (being firmly pressed into), the other end is placed on aluminium section bar groove;
3, the rolling device then passing through causes the other end from being pressed into one end roll extrusion of aluminium base on aluminium base, and light source aluminium base has been interference fit into one with aluminium section bar after roll extrusion like this.
LED light source board fixing structure of the present invention and installation method, compare with the normally used connected mode that screws, beats other forms such as glue, subsides bond plies, has advantages of following:
Simple, easy to operate when 1, described structure is assembled, can manually carry out roll extrusion or automatic rolling, can realize mechanization and produce in enormous quantities, greatly enhance productivity, than screwing, beat glue, subsides bond plies etc. mode, save time, and solid and reliable;
2, after the invention of this technique, can improve the heat-conducting effect of system, aluminium base with heat-dissipation aluminum sectional material by roll extrusion after, can good interference fit, each heat-transfer area is more fully contacted, increased the area of heat conduction, improved heat conductivility.
