Description
Technical field
The invention belongs to LED light source domain, more particularly to it is a kind of convenient LED light source installed.
Background technology
In current LED industry, when LED fluorescent lamp tube is manufactured, light source aluminium base is fixed on radiating aluminum alloy casing
Common method is mostly adopted and is screwed, applies heat conduction bonded adhesives, paste the modes such as bond plies.Such as adopt and be screwed,
It is not only time-consuming during production, and easily loosen, thus there is potential safety hazard, furthermore heat-conducting effect is nor ideal,
Because centre there will necessarily be the air gap, cause larger thermal contact resistance.Such as using coating heat-conducting cream, on the one hand preferably lead
The heat-conducting cream of hot coefficient is expensive, and low thermal conductivity factor does not reach good heat-conducting effect again, on the other hand applies this cream
It is fairly time consuming.These shortcomings, all limit the popularization and application of LED illumination technology.
The content of the invention
The present invention is to solve deficiency in this respect, there is provided a kind of new LED fluorescent lamp tube light source board fixation side
Formula, is assembled by machinery, so on the one hand assembles fairly simple, can largely save production cost, on the other hand may be used
It is high by property, heat conductivility can be improved again.
Specifically, the convenient LED light source installed of the present invention, including LED-baseplate and heat sink section bar, wherein, LED
Substrate includes substrate and the LED being arranged on substrate, and heat sink section bar is the hollow columnar structures isometric with substrate, and side is provided with appearance
Receive the draw-in groove of substrate, two sides of draw-in groove are inclined domatic under being respectively equipped with the diagonal.
Further, the draw-in groove and substrate interference fit, the width of draw-in groove are less than the width of substrate, and such design is
In order that substrate is more closely embedded and chimeric with heat sink section bar, optimal radiating effect is reached.
Further, the substrate is aluminium base.
Likewise, the heat sink section bar is heat-dissipation aluminum sectional material.
The convenient LED light source installed of the present invention, with it is usually used screw, gluing water, patch bond plies
Connected mode etc. other forms is compared, and is had the following advantages that：
1st, it is simple when the structure is assembled, it is easy to operate, can manually be rolled or automatic rolling, achievable mechanization is in high volume
Production, greatly improves production efficiency, than screwing, gluing water, patch bond plies etc. mode it is time-consuming, and firmly may be used
Lean on；
2nd, the heat-conducting effect of system can be improved after this art inventions, aluminium base is with heat-dissipation aluminum sectional material by the way that after rolling, energy is well
Interference fit, makes each heat-transfer area more be fully contacted, and increases the area of heat conduction, improves heat conductivility.

Specific embodiment
Below in conjunction with accompanying drawing, nonrestrictive explanation is carried out to the convenient LED light source installed of the present invention, it is therefore an objective to
It is easy to the public to more fully understand the technology contents.
Such as Fig. 1-6, the convenient LED light source installed of the present invention, including LED-baseplate and heat sink section bar, wherein, LED
Substrate includes substrate 11 and setting plurality of LEDs 12 on the substrate 11, and heat sink section bar 2 is the hollow columnar knot isometric with substrate 11
Structure, side is provided with the draw-in groove 20 for accommodating substrate 11, and two sides of draw-in groove 20 are inclined domatic 21 under being respectively equipped with the diagonal.At this
In embodiment, the material of substrate 11 and heat sink section bar 2 is aluminum or aluminum alloy, with preferable heat-conducting effect.
The draw-in groove 20 and the interference fit of substrate 11, the width of draw-in groove 20 are less than the width of substrate 11, and such design is
In order that substrate 11 is more closely embedded and chimeric with heat sink section bar 2, optimal radiating effect is reached.
Specifically, the light source aluminium base of shown LED fluorescent lamp tube, and heat-dissipation aluminum sectional material, wherein heat-dissipation aluminum sectional material two
Sideband slips into gradient, and the tolerance dimension of aluminium base width and the tolerance dimension of aluminium section bar two side width are adapted to interference fit
, first be put into section groove (be firmly pressed into) for one end of LED light source aluminium base by device, and the other end is placed on aluminium section bar groove, then
By the rolling device designed exclusively for this, rolled from the one end for being pressed into aluminium base on aluminium base and cause the other end, such light
Source aluminium base with aluminium section bar after rolling by being interference fit into one.
It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention,
Some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
