Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
The LED 100 with papery radiator structure of first embodiment of the invention, please refer to Fig. 1 to Fig. 6.
Please refer to Fig. 1, Fig. 2 and Fig. 3.A kind of LED 100 with papery radiator structure, mainly comprise radiator and LED light source plate 30, this radiator comprises papery radiating piece 10, this radiating piece made of paper comprises end face 11 and side 12, this LED light source plate 30 is arranged on the end face 11 of this radiating piece made of paper and thermally coupled with this end face 11, the heat that this LED light source produces by this radiating piece made of paper is delivered to side 12 by end face 11, and is outwards distributed by side 12.
Please refer to Fig. 6.This papery radiating piece 10 comprises paper substrates 103 and is arranged on the heat-conducting layer 102 on this paper substrate, and this heat-conducting layer 102 is arranged on inner surface or the outer surface of this paper substrates 103, and this heat-conducting layer 102 at least covers portion top surface 11 and the side 12 of this radiating piece.This heat-conducting layer 102 is arranged on the outer surface of this paper substrates 103 and this heat-conducting layer 102 is thermally coupled with this LED light source plate 30.Preferably, this heat-conducting layer 102 is flexible metal thin layer.This radiating piece 10 made of paper is made into integration, and the bending of this side 12 is arranged under this end face 11.
Preferably, this papery radiating piece 10 also includes protective layer 101, and this protective layer 101 is made for dielectric film, and this protective layer 101 covers the outer surface of heat-conducting layer 102.
Please refer to Fig. 1, Fig. 2 and Fig. 3.Also comprise bracing frame 20, the hard material that this bracing frame 20 is greater than this paper radiator by hardness is made, as plastics, timber or metal material etc.This bracing frame 20 comprises fixed part 21 and side lever 22, the top of this side lever 22 is connected with fixed part on this 21, this papery radiating piece 10 is shell structure, and the end face 11 of this papery radiating piece 10 is fixed on this on fixed part 21, and the side 12 of this papery radiating piece 10 is set on this side lever 22.
This bracing frame 20 also comprises lower fixed part 23, and the bottom of this side lever 22 is connected with this lower fixed part 23.Also comprise lamp holder 40, this lamp holder 40 is connected with this lower fixed part 23.
Please refer to Fig. 2, Fig. 3, Fig. 4 and Fig. 5.Preferably, the side 12 of this papery radiating piece 10 is provided with protruding salient point 121, scale radiator structure 121 or the bar shaped heat radiation fin structure 121 by being bent to form hollow.By being provided with protruding salient point 121, scale radiator structure 121 or the bar shaped heat radiation fin structure 121 by being bent to form hollow, increasing area of dissipation greatly, effectively raising radiating effect.The end face 11 of this papery radiating piece 10 splits the multiple snapping sheet 111 of formation, and this snapping sheet 111 is attached to the upper fixed part 21 of this bracing frame 20.
Because bracing frame 20 is made up of plastics, timber or metal material, therefore bracing frame 20 has enough mechanical strengths for supporting fixed L ED light source board 30 and cell-shell, avoids the subsiding of papery radiating piece 10, problem that intensity deficiency cannot be fixed.Because bracing frame 20 includes side lever 22 1 aspect for making upper fixed part 21 and papery radiating piece 10, the drive plate etc. of fixing light fixture can also be used for simultaneously, simplify structure, easy to use greatly.Owing to being provided with lower fixed part 23 for fixing lamp holder 40 on bracing frame 20, by fixed part being arranged to the helicitic texture that matches with lamp holder 40 or other structures, the advantage that structure is simple, firmly can fix lamp holder 40 can be had.
When this LED 100 with papery radiator structure works, the material used due to papery radiating piece 10 comprises paper substrates 103, heat-conducting layer 102 and protective layer 101.Use paper substrates 103 can reduce weight and the cost of papery radiating piece 10 greatly on the one hand, the manufacture craft of papery radiating piece 10 can also be simplified simultaneously, the manufacturing of various structures can be met.And heat-conducting layer 102 is set, and be preferably flexible metal thin layer, when not affecting flexible characteristic, ensure that papery radiating piece 10 has excellent radiating effect, the heat that can be produced by LED light source rapidly transmits and fast eventually to exhaling outward.And protective layer 101 can play the effect of protection heat-conducting layer 102; LED light source plate 30, drive plate and heat-conducting layer 102 can be separated; avoid heat-conducting layer 102 directly to contact with LED light source plate 30, drive plate and cause short circuit, thermosphere also can be avoided simultaneously to be directly exposed to the problem such as oxidized in air.
In sum, the radiator that the LED 100 with papery radiator structure is made by adopting papery radiating piece 10 and bracing frame 20, greatly reduces weight and the production cost of radiator on the one hand, meets the demand manufactured.On the other hand, use papery radiating piece 10 can the radiator structure being of value to heat radiation of manufacturing structure complexity, Optimization Technology.The end face 11 of papery radiating piece 10 is directly formed thermally coupled with LED light source plate 30 simultaneously, and the heat that LED light source produces is delivered to side 12 by end face 11, and outwards disperses.Have and can be good at heat transfer and dispelled the heat by cross-ventilation.Compared with common metal heat sink, this radiating piece made of paper has lightweight, shaping advantage easy to manufacture.Whole light fixture has that structure is simple, radiating effect, radiating piece lightweight and the advantage that production cost is low.
Understandable, papery radiating piece 10 is by the salient point 121 of folded projections, scale radiator structure 121 or the bar shaped heat radiation fin structure 121 by being bent to form hollow.Mainly in order to increase area of dissipation, thus improve radiating effect further.Certainly, when meeting increase area of dissipation, the foldable structure of papery radiating piece 10 may not be the structure in embodiment.
