Fig. 1 means the LED illumination radiator 101 of the first execution mode.This LED illumination is characterised in that with radiator 101, with respect to the face 1021 that LED element 100 is installed on to the either party in the table back of the body, 1022 substrate 102, flat radiating fin 103, 104 are integrally formed in the face 1021 of the either one or both in the tables back of the body of substrate 102, on 1022, radiating fin 103, the face 1021 of either party 104 back ofs the body of the table from substrate 102, 1022 erect and arrange towards foreign side, and be spaced from each other interval and form, above-mentioned radiating fin 103, the fin 103 mutually extended towards identical direction in 104, the either party of 104 sheet number in the back of the body of the table with substrate 102 face 1021, on the cross section arbitrarily of 1022 quadratures, be below 2.Wherein, substrate 102 forms assembling face of the present invention, and radiating fin 103 forms the first fin section of the present invention, and radiating fin 104 forms the second fin section of the present invention.
Particularly, in Fig. 1, with stereogram, mean first execution mode of LED illumination of the present invention with radiator 101, in Fig. 2～7, mean first～six variation of LED illumination of the present invention with the first execution mode of radiator 101 with stereogram respectively.
The basic structure of radiator:
At first, the LED illumination of the first execution mode of the present invention in Fig. 1～7 described by the identical basic structure of radiator 101.In above-mentioned Fig. 1～7, LED illumination of the present invention has the flat substrate 102 that LED element 100 is installed equally with radiator 101.This substrate 102 has respectively two faces 1021,1022 of the table back of the body in the y of each figure direction (above-below direction) side, and these faces 1021,1022 x along each figure, z direction are extended.Install and support LED element 100 on the either party of this flat substrate 102 in two faces 1021,1022 of the above-mentioned table back of the body face, in Fig. 1～7, for convenient, installed surface 1021 using the face of the upside of each figure as LED element 100, install LED element 100 at the central portion on the plane of installed surface 1021.And, be also for convenient, using the opposing party's of the downside of each figure face as the back side 1022.
And the table back side 1021,1022 of substrate 102 has with the face quadrature of either one or both (with the bearing of trend of face=x of each figure, z direction quadrature) and to the y direction (above-below direction) of each figure stretches out and the flat radiating fin 103～106 that extends.Above-mentioned flat radiating fin 103～106 is erect and is arranged at the table back side 1021,1022 of substrate 102 with the form towards foreign side, but may not as shown in Fig. 1～7, make the table back side 1021,1022 quadratures of the angle with 90 degree of flat heat radiation side and substrate 102.For example, the heat radiation side also can be erect and arrange towards foreign side obliquely with respect to the table back side 1021,1022 of substrate 102 to be less than 90 degree or to surpass 90 angles of spending.But, in either case, above-mentioned flat radiating fin 103～106 on material all with substrate 102 one and form continuously.That is, at least flat face 1021,1022 of respectively showing the back side and substrate 102 of above-mentioned flat radiating fin 103～106 forms incessantly continuously.
Therefore, form make from the heat of LED element 100 via face (surface) 1021 of the LED element installation side of substrate 102 to the back side 1022, each radiating fin 103～106 around the continuous heat-transfer area that conducts heat continuously of the face of side, thickness of slab direction.And, also form from the continuous radiating surface of described continuous heat-transfer area continuous radiation heat.
It should be noted that, about the shape of substrate 102, in Fig. 1～7, exemplify tabular or the flat shape of rectangle (square).But, the shape of this substrate 102 can be according to LED illumination the purposes with radiator 101, and suitably select circle, triangle, polygon, the flat shape such as unsetting or whole be cylindrical shape, square tube shape or the 3D shape with difference of height etc. etc.
The feature of radiating fin:
The basic structure self of LED illumination use radiator 101 of the present invention described above at first sight, seems without big difference with the structure of illustrative existing radiator 4 in Figure 47.But, have following relatively big difference point with existing radiator 4 on the method for the configuration of this flat radiating fin 103～106: exist in the narrow space at vehicle-mounted illuminating housing or the heat radiation that will be undertaken by radiation that needs in enclosure space to consider as the research of main body.
At first, it is prerequisite that LED of the present invention illumination be take the basic structure of described radiator with radiator 101, and the flat radiating fin 103～106 of the sheet number of 2～8 of totals that preferably will arrange respectively on two faces 1021,1022 of substrate 102 is spaced from each other interval and continuous and form with the face 1021,1022 of substrate 102.
And above-mentioned radiating fin 103～106 comprises parallel state, and the sheet number of the fin mutually extended towards identical direction is below 2 in the cross section arbitrarily of two faces, 1021,1022 quadratures with substrate 102.That is in the cross section arbitrarily of the radiator 101 of, cutting open in the cross section of the direction arbitrarily of two faces, 1021,1022 quadratures by with substrate 102, be below 2.
The meaning of the regulation of radiating fin bearing of trend:
At this, said in the present invention " mutually towards identical direction, extending " comprises parallel state certainly, but and be not only the proper parallel meaning, the angle of the bearing of trend of radiating fin tabular side each other can be slightly different.In the present invention, its purpose is, on the direction arbitrarily of the three-dimensional of radiator, all eliminates radiating fin excessive coincidence each other, material do not wasted, and obtained the high performance of radiation efficiency of heat.Therefore, in the scope that does not hinder this purpose or effect, even the angle of the bearing of trend of radiating fin tabular side each other is slightly different, also it can be regarded as mutually and extend towards identical direction.This is that the angle of the bearing of trend of radiating fin tabular side each other due to no matter is slightly different, still strictly parallel and its angle does not have difference, on overlapping, the direction that the radiating fin that should limit in the present invention is identical towards each other there is no marked difference.
About the different standard of this angle, as long as the bearing of trend angulation of radiating fin tabular side each other is below 30 degree, just regards radiating fin as and extend towards identical direction each other.On the contrary, if the bearing of trend angulation of radiating fin tabular side each other surpasses 30 degree, can not regard radiating fin as and extend towards identical direction each other.
In Fig. 1 described later～7, two radiating fins form the form that clips LED element 100 and mutually extend towards identical direction each other, and arrange in parallel to each other, the rectangular shape ground that LED element 100 is centered by it surrounds surrounding, and quadrature (the at right angles intersecting) configuration each other of adjacent radiating fin.But, in the present invention, be not limited to such configuration, can be on the circumference of point centered by LED element 100 or on circular arc, surround LED element 100 around, and, when changing in turn the angle of tabular side, the radiating fin devices spaced apart is configured to for example domino and topples over shape.
In addition, it is in order to prevent with respect to certain direction in three dimensions that the sheet number of the mutual fin extended towards identical direction is defined as to " (in the cross section arbitrarily of the radiator of being cut open by the cross section of this direction) is below 2 in the cross section arbitrarily of two faces, 1021,1022 quadratures with substrate 102 ", the situation that fin exceedingly overlaps each other.As described later, even be a slice fin, also exist L word shape or
the situation with a plurality of flat radiating surfaces (heat radiation side) that extend to different directions that the word shape is such.Be not only flat fin, for the fin of such shape with bearing of trend or variform a plurality of radiating surfaces, will be for example flat shape form L word shape or
each line interval of word shape is also regarded respectively single fin as, observes the sheet number (overlapping conditions) on same direction.According to such viewpoint, in the cross section arbitrarily of the face quadrature of the either party in the back of the body of the table with substrate, by making to the sheet number of the identical fin towards extending, be below 2, thus can avoid radiating fin each other or the heat radiation side of radiating fin face with each other and situation about overlapping.; this is because afore mentioned rules is; it is no matter whether the radiating surface of identical fin; all the sheet number of the radiating surface of radiating fin (heat radiation side) is regarded as to the sheet number of fin; and the position regardless of two faces 1021,1022 of substrate 102; all avoid excessive coincidence, thereby form described regulation below 2.
In this, when the performance as different from afore mentioned rules, and the sheet number of the fin that will mutually extend towards identical direction has been stipulated out the absolute sheet number of radiating fin while being defined as for the time being " being all below 2 in arbitrary 1021,1022 at substrate 102 ".Therefore, not by L word shape or
the radiating surface of the different directions of the radiating fin that the word shape is such is regarded the sheet number of fin as, thereby may produce because the position of two faces 1021,1022 of substrate 102 is different excessive coincidence.Therefore, be defined as described " (in the cross section arbitrarily of the radiator of being cut open by the cross section of this direction) is below 2 in the cross section arbitrarily of two faces, 1021,1022 quadratures with substrate 102 ".
About the shape of this flat radiating fin 103～106, in Fig. 1～7, exemplify the shape that global shape or tabular side are rectangle (square), but also can select to be not limited to flat shape or the 3D shape of this rectangle.For example, as the situation that makes flat radiating surface (heat radiation side) for example, to a plurality of extensions of different direction (90 degree more than), also can for adjacent radiating fin 103,104 each other or 105, the 106 L word shapes that become one such, adjacent radiating fin 103,104,103 each other or 105,106,105 become one such
the word shape.As long as can manufacture, can be not only above-mentioned flat radiating surface (heat radiation side), can also there is circular-arc or curvilinear radiating surface (heat radiation side) or global shape.In addition, towards the shape in the thickness of slab cross section of foreign side or thickness also can be L word shape on height and position or stepped ground is different.And, can also suitably select radiating surface is formed the situation of circle, triangle, polygon, the face shape such as unsetting.
Below, the of the present invention concrete execution mode of key diagram 1～7, and wherein, describe the meaning of the regulation of the sheet number of flat radiating fin 103～106 of the present invention, configuration.That is the meaning that, the sheet number that makes flat radiating fin 103～106 is preferably added up to 2～8 this point describes.In addition, also in above-mentioned radiating fin 103～106, the meaning that the sheet number of the fin mutually extended towards identical direction is below 2 in the cross section arbitrarily of the radiator 101 when cutting open with arbitrary 1021 of substrate 102, the cross section of the direction arbitrarily of 1022 quadratures describes.
The first execution mode of Fig. 1:
The flat radiating fin 103,104 of Fig. 1 is provided with 4 in the LED element installed surface that LED element 100 the is supported 1021 sides totals of substrate 102, and face 1021 one of flat each side of radiating fin 103,104 and substrate 102 and setting continuously.At the opposing party's the back side, 1022 sides do not arrange radiating fin, only have the flat back side 1022.
And, between the radiating fin 103,104 of above-mentioned LED element installed surface 1021 side settings is clipped in LED element 100 and respectively arrange symmetrically 2, and the radiating fin 103,103 of the left and right sides of figure each other and the radiating fin 104,104 of the upper and lower sides of figure be each the form of mutually extending towards identical direction, and spread configuration in parallel to each other.That is, mutually opposed flat radiating fin 103,103 is each other and 104,104 at LED element installed surface 1021, be that face side is formed on the position that LED element 100 is clipped in the middle each other.And, in above-mentioned radiating fin 103,104, the sheet number (in cross section arbitrarily of the radiator 101 of being cut open by the cross section of this direction) in the cross section arbitrarily of face 1021,1022 quadratures with substrate 102 of the fin mutually extended towards identical direction is all 2.
And, in radiating fin 103,104 adjacent radiating fin each other quadrature form, configure (at right angles intersecting), surround (centered by LED element 100) the rectangular shape surrounding between LED element 100 is clipped in, and each tabular side of the large radiating fin 103,104 of the radiance of heat is respectively towards x direction, z direction.And the LED element installed surface 1021 that the radiance of the heat of substrate 102 is large and the opposing party's the back side 1022 are towards the y direction.
In addition, each face 1023,1024,1025 of the thickness of slab of the surrounding of substrate 102 (thickness) direction, the left side that 1026(1023 is figure, 1024 downsides that are figure, 1025 right sides that are figure, 1026 is the upside of figure) with described each face 1021,1022, compare, smaller on area, but, towards all directions of x, z, become the radiating surface of heat to above-mentioned direction.In this, each face (upper surface of thickness of slab (thickness) direction of each radiating fin 103,104, the both ends face) too, although compare with described tabular side, smaller on area, but the number of face is many, upper surface, both ends face all add up to respectively each 4 faces and, towards the x, y, z all directions, become the radiating surface of heat to above-mentioned direction.
Therefore, in the planar side of radiating fin 103,104, although in opposed facing 2 paired faces of the side that LED element 100 is installed, radiating surface overlaps, but on the direction arbitrarily of the three-dimensional of above-mentioned x, y, z, the radiating surface of radiating fin does not excessively repeat, and there is no the waste of material.Therefore, the effect of the formation effect of the continuous heat-transfer area conducted heat continuously to the face of the side around the back side 1022, each radiating fin 103,104, thickness of slab direction via the installed surface 1021 of substrate 102 at the above-mentioned heat from LED element 100 and the synergy of the formation effect of the continuous radiating surface from above-mentioned continuous heat-transfer area continuous radiation heat, can access high radiation efficiency.
The sheet number of radiating fin:
Sheet number at the radiating fin that makes mutually to extend towards identical direction further reduces, thereby in the situation that with the cross section arbitrarily of face 1021,1022 quadratures of substrate 102 in all only be provided as 2 of preferred lower limit, only become 2 reservations in the either one or both in the radiating fin of the upper and lower sides of the either one or both in the radiating fin of the left and right sides of Fig. 1 103,103, figure 104,104, and the form that other radiating fin is removed.In this case, the radiating fin of the left and right sides of Fig. 1 103,103 can be retained each other, also the radiating fin of the upper and lower sides of Fig. 1 104,104 can be retained each other, radiating fin 103,104 respectively can also be retained to one party.
On the other hand, in the situation that the sheet number of flat radiating fin becomes many, on a direction in the three-dimensional of x, y, z, the radiating surface of radiating fin repeats, produce the waste of material, although space occupancy is high, the radiation efficiency of heat (radiating efficiency) reduces.Therefore, adding up to below 8 of the sheet number that the sheet number of the radiating fin that arranges is arranged respectively on two faces 1021,1022 of the table back of the body of substrate 102, be preferably the scope of 2～8.But, in Fig. 1～7, when being only makes identical radiating fin 103～106 respectively directly in the situation that separate on the bearing of trend of heat radiation side, be divided into form several or that fine separate, cut apart, regard 1 of identical radiating fin as.
Problem when the total sheet number of this flat radiating fin becomes many, as shown in the comparative example of Figure 50, produces too when the sheet number of the fin mutually extended towards identical direction (abreast) is too much like this while being (in the situation that in the cross section arbitrarily of the radiator 101 of being cut open by the cross section of the direction arbitrarily of two face 1021,1022 quadratures of the back of the body of the table with substrate 102 all more than 3) in the cross section arbitrarily of two face 1021,1022 quadratures of the back of the body of the table with substrate 102 more than 3.In the comparative example of Figure 50, if respectively there are 4 in the sheet number of the fin extended to the direction be parallel to each other on two sides' of substrate 102 the table back side 1021,1022, become identical with a plurality of radiating fins that are arranged in parallel of the conventional example of Figure 47, on a direction of the three-dimensional of x, y, z, the radiating surface of radiating fin repeats, produce the waste of material, although space occupancy is high, the radiation efficiency of heat reduces.
The first variation of the first execution mode of Fig. 2:
The flat radiating fin of Fig. 2 means not only one side of the LED element installed surface (surface) 1021 of such substrate 102 at Fig. 1, also in the opposing party's of substrate 102 the back side 1022 sides, is provided with the form of radiating fin 105,106.Particularly, except a side of the LED element installed surface 1021 of the substrate 102 at Fig. 1 is provided with 4 flat radiating fins 103,104, also symmetrical and radiating fin 105,106 each 2 totally 4 is set at the opposing party's the back side 1022 sides and LED element installed surface 1021, thus add up to 8 of the preferred upper limit that is provided as the sheet number.
At the radiating fin 105,106 of the above-mentioned back side 1022 side settings and to be provided with the flat radiating fin 103,104 of 4 in the LED of described substrate 102 element installed surface 1021 sides fully same, and form symmetrical configuration on the above-below direction of figure.; between LED element 100 is clipped in and respectively arrange symmetrically 2; and the radiating fin 105,105 of the left and right sides of figure each other and the radiating fin 106,106 of the upper and lower sides of figure form each other the form of mutually extending towards identical direction, and spread configuration in parallel to each other.; 1022 sides overleaf; mutually opposed flat radiating fin 105,105 each other and 106,106 each other with LED element installed surface 1021 be face side flat radiating fin 103,103 each other, 104,104 same each other, be formed on the position that the position suitable with LED element 100 installation sites of rear side is clipped in the middle.In other words, flat radiating fin is formed on the position that LED element 100 is clipped in the middle on two sides' of the table back of the body of substrate 102 face.And, in above-mentioned radiating fin 105,106, the sheet number (in cross section arbitrarily of the radiator 101 of cutting open in the cross section by this direction) in the cross section arbitrarily of face 1022 quadratures with substrate 102 of the fin mutually extended towards identical direction is all 2.
And, radiating fin 105,106 by adjacent radiating fin each other the form of quadrature (at right angles intersecting) surround the rectangular shape surrounding centered by the installation correspondence position of such element of the LED by the back side 1,022 100, and each tabular side of the large radiating fin 105,106 of the radiance of heat is respectively towards x direction, z direction.And the LED element installed surface 1021 that the radiance of the heat of substrate 102 is large and the opposing party's the back side 1022 are towards the y direction.
In addition, be not only substrate 102 surrounding the thickness of slab direction each face 1023,1024,1025,1026, be provided with each face (upper surface, both ends face) of thickness of slab direction of the flat radiating fin 103,104 of 4 in the LED of described substrate 102 element installed surface 1021 sides, and each face of the thickness of slab direction of each radiating fin 105,106 of the back side 1022 sides (lower surface, both ends face) also becomes the radiating surface of heat.Each face of the thickness of slab direction of each above-mentioned radiating fin is smaller on area, but the number of the face of upper and lower surface, both ends face all becomes 2 times of Fig. 1, and adding up to respectively is respectively 8 faces and, towards the x, y, z all directions, become the radiating surface of heat to above-mentioned direction.
Therefore, the situation of Fig. 2 is on the direction arbitrarily of the three-dimensional of above-mentioned x, y, z, and especially the radiating surface of radiating fin does not repeat, and there is no the waste of material, although space occupancy is low, can access the high radiation efficiency of heat.
Second, third of Fig. 3,4, the first execution mode of 5, the 4th variation:
The flat radiating fin of Fig. 3,4,5 variation is expressed as follows form: the situation of the Fig. 2 that is the upper limit from the sheet number, arbitrary radiating fin of the opposing party's of a side of the LED element installed surface 1021 of substrate 102 or substrate 102 the back side 1022 sides is omitted.
The second variation of Fig. 3 is with respect to the configuration of the radiating fin of Fig. 2, and the radiating fin of LED element installed surface 1021 sides of substrate 102 is become 3 after 1 omission of the downside of the figure in 2 of radiating fin 104.And the radiating fin of the opposing party's the back side 1022 sides also becomes 3 after 1 omission in the left side of the figure in 2 of radiating fin 105, add up to 6 radiating fins are set, and form the configuration of the asymmetrical radiating fin on the above-below direction of figure.
The 3rd variation of Fig. 4 is with respect to the configuration of the radiating fin of Fig. 2, and the radiating fin of LED element installed surface 1021 sides of substrate 102 is only become the radiating fin of the left and right sides of the figure after 104,104 these 2 omissions of the radiating fin of the upper and lower sides of figure 103,103 these 2.And, the opposing party's the back side 1022 sides also only become the radiating fin of the left and right sides of the figure after 106,106 these 2 omissions of the radiating fin of the upper and lower sides of figure 105,105 these 2, add up to 4 radiating fins are set, and maintain the configuration of the radiating fin of the symmetry on the above-below direction of figure.
The 4th variation of Fig. 5 is with respect to the configuration of the radiating fin of Fig. 2, the radiating fin of LED element installed surface 1021 sides of substrate 102 is only become the radiating fin of the left and right sides of the figure after 104,104 these 2 omissions of the radiating fin of the upper and lower sides of figure 103,103 these 2, and this point is identical with Fig. 4.And, the radiating fin of the opposing party's the back side 1022 sides is only become the radiating fin of the upper and lower sides of the figure after 105,105 these 2 omissions of the radiating fin of the left and right sides of figure 106,106 these 2, add up to 4 radiating fins are set, and form the configuration of the asymmetrical radiating fin on the above-below direction of figure.
The the 5th, the 6th variation of Fig. 6, the first execution mode of 7:
LED shown in Fig. 6,7 illumination means from the sheet metal with fixing thickness of slab such as aluminium etc. substrate 102( face 1021,1022 with radiator 101), the integrally formed execution mode of flat radiating fin 103～105.
In this case, flat radiating fin 103～105 is that z direction (above-below direction of figure) is carried out Bending Processing by the end side from substrate 102 towards the bearing of trend of face separately, thereby integrally formed on material.In the 5th variation of Fig. 6, fin 103,103,104,104 upper sides to figure are bent into to opposed facing shape.In the 6th variation of Fig. 7, fin 104,104 upper sides to figure are bent into to opposed facing shape, and fin 103,103 lower side to figure are bent into to opposed facing shape.And, for configuration, the sheet number of above-mentioned flat radiating fin 103～105, Fig. 6 is identical with the situation of Fig. 1, Fig. 7 is identical with the situation of Fig. 5.But, because radiating fin 103,104 forms by the end bending by substrate 102, so lay respectively at the configuration structure difference on the end of substrate 102.
Principle, the effect of heat radiation:
Radiator of the present invention 101 by such is arranged on to the space of the convection current that there is no air and the principle (effect) of carrying out the heat radiation in LED when illumination describes.When the LED element 100 that makes assembling on LED element installed surface 1021 is luminous, follow in this, by the department of assembly (not shown) of the bottom of LED element 100, the LED element installed surface 1021 to substrate 102 conducts the heat that LED element 100 sends (heat flux) Q.And then, be transmitted to heat Q on LED element installed surface 1021 not only to the radiating fin 103,104 of installed surface 1021 sides, but also to the back side 1022, the radiating fin 105,106 of these back side 1022 sides is with high level about equally and do not transmit (conduction) with each above-mentioned radiating surface with (lagging behind) continuously and rapidly.Therefore, from the convection current of the heat-delivery surface of above-mentioned fin and the heat radiation especially undertaken by radiation equally to carry out more than certain level, thereby can improve radiating efficiency.
At this, as regulation of the present invention, in radiating fin 103～106, the sheet number of the fin mutually extended towards identical direction is all, below 2, on identical direction, can excessively not overlap in the cross section arbitrarily of face 1021,1022 quadratures with substrate 102.Therefore, the heat Q of above-mentioned transmission is respectively towards the three-dimensional of x, y, z, and from promptly peripherad enclosure space (heat-dissipating space) radiation effectively of surperficial philosophy of described each radiating surface of the installed surface 1021 of substrate 102, the back side 1022, radiating fin 103～106.Therefore, the heat that LED element 100 sends all be take heat dissipation capacity to the direction arbitrarily of three-dimensional x, y, z and is dispelled the heat as the high radiation efficiency more than certain.This be due to, although the sheet number of radiator 101 radiating fins 103～106 of the present invention is few, but in the heat-dissipating space of the sealing in the efficiency of its heat radiation in the ligthing paraphernalia few by the cross-ventilation of radiation domination, all large with respect to each projected area of all directions of x, y, z direction.Radiator 101 of the present invention has good characteristic as follows: although be the few simple structure of sheet number of radiating fin 103～106, the radiating efficiency of every heat radiation unit are is good.
At this, configuration and while being dispelled the heat by radiation in need to the narrow space at vehicle-mounted illuminating housing or in enclosure space, the size of the projected area on the x, y, z direction of principal axis (three-dimensional) meaned in each figure determines its efficiency, this projected area is larger, and the radiation efficiency of heat more improves.
For this point, the conventional example of Figure 47 or the radiator of comparative example 4 be due to the total on the plane of the upside of the projected area of the y direction plane that is baseplate part 2 and fin section 3, so fin section 3 do not have overlappingly each other, therefore there is no the waste of material, and projected area is large.Therefore but the total of the side of the side that the projected area of z direction is baseplate part 2 and fin section 3, become comb teeth-shaped and space is many, become 50% little area of the gross area that height that the length that does not meet baseplate part 2 is multiplied by fin section 3 obtains.In addition, the total in the front of the front that the projected area of x direction is baseplate part 2 and fin section 3, although there are for example 4 in fin section 3, but they repeat, thereby be the projected area identical with 1, the waste of material is many, and the radiation efficiency of the heat of every area of dissipation is low.That is, on the x direction, a plurality of fins repeat and occupy space, although its space occupancy is high, projected area is little, and the radiation efficiency of heat is low.And the sheet of this x direction fin is counted surplus, because the waste of this superfluous fin material is also large, also exist weight to become heavy problem.
In other words, the certain step-down of radiation efficiency of the heat of a direction of the x, y, z direction of principal axis (three-dimensional) of the radiator 4 of the conventional example of Figure 47 or comparative example.Consequently, can't improve the radiation efficiency of heat of certain direction of three-dimensional, therefore the radiation efficiency step-down of total heat.In addition, on above-mentioned x direction etc., the waste that the sheet of fin is counted surplus and material is also large.That is, in above-mentioned prior art, something in common is, can't be formed on the direction arbitrarily of three-dimensional of radiator, and material does not all have waste, although and space occupancy low, the radiator that the radiation efficiency of heat is high.
In addition, about this point, TOHKEMY 2010-146817 communique too, in a plurality of arrangements
on the direction that the radiating part of the handle spoon of word shape part repeats, space occupancy is high, but the radiation efficiency of heat is low, and from the radiation efficiency of total heat of three directions of three-dimensional, especially the waste of the material of x direction is many.In addition, there is the large restriction of the area of size self for guaranteeing radiator or described radiating part side on the width of the peristome of described slit-shaped, thereby must form narrow width, therefore, in the time of in the space that is applicable to sealing, the raising of the radiating efficiency dispelled the heat by the convection current of air also can't be brought into play actually as expecting.
The sealing of heat-dissipating space around of radiator of the present invention, volume is little and almost do not have under such use (setting) state of the convection current of air, the most applicable under use (setting) environment that almost can't expect to be dispelled the heat by the convection current of air.Under such environment for use, in order to dispel the heat, need to be centered by being dispelled the heat by radiation, at the radiating surface surface area by increasing fin etc. and in the above-mentioned existing heat spreader structures using the convection current of air as main heat dispersion, the heat radiation of being undertaken by this radiation is insufficient, and integral body can't realize effective heat radiation.With respect to this, in radiator of the present invention, the heat radiation of being undertaken by the radiation of the heat from radiating surfaces such as described heat radiation sides is main body, can be referred to as to be best suited for the radiator of use (setting) environment that almost can't expect the heat radiation undertaken by the convection current of air.
And, each radiating surface that comprises LED element installed surface 1021 and radiating fin due to be between them not via the integrative-structure on composition surface, therefore can not produce the above-mentioned contact heat resistance that both produce while engaging that will make respectively.Therefore, easily, consequently, the heat dispersion of radiator integral significantly improves the heat conduction between LED element installed surface 1021 and each radiating surface.And, because the structure of radiator 101 is the structure of radiating fin towards each direction of three-dimensional x, y, z, so rigidity is high.Therefore, even the purposes of being vibrated in vehicle-mounted illumination etc. also can in the situation that do not use special stiffener etc. to keep its shape, can realize freedom from repairs and high life.
The identical item that comprises the first execution mode of each variation:
On each radiating surface of the installed surface 1021 of substrate 102 described above, the back side 1022, radiating fin 103～106, can be according to purposes or the installation position of radiator 101, the excision processing of the above-mentioned face of excision or the shaping processing of the three-dimensional of concavo-convex or step etc. is set on one one by each face above-mentioned, arrange space, slit or partial shape etc. that parts are installed use.And the heat radiation side, according to the needs of parts installation etc., also can be omitted the part of each face or the change shape.
(aluminium)
Wherein, as the necessary characteristic that has both radiator 101, be the raw material of intensity, rigidity, lightweight, corrosion resistance, heat transmitting, hot thermal diffusivity, processability etc., preferred aluminium (fine aluminium) or aluminium alloy.King-sized 1000 fine aluminiums that are of stipulating in AA or JIS specification of aluminium (fine aluminium) or the desired thermal conduction characteristic of the preferred radiator of aluminium alloy and heat dissipation characteristics.
When the lightweight of considering radiator, necessary intensity, rigidity and pull and stretch processability (formability), the thickness of slab (thickness) when the thickness of slab (thickness) of substrate 102, radiating fin 103～106 or raw material are sheet metal is preferably selected in the scope of 0.4mm～4mm.When this thickness of slab is too thin, can't guarantee necessary intensity, rigidity or the processability (formability) of radiator.On the other hand, when this thickness of slab is too thick, can sacrifice the lightweight of radiator.
(emissivity of radiating surface)
Radiator of the present invention is in order to obtain high thermal diffusivity, and the emissivity ε of preferred described sheet metal is more than 0.6.Therefore, before pull and stretch processing, the precoating of the coating of black that can be high to the whole surface enforcement rate of heat dissipation of feed metal thin plate, grey, white etc. is processed (application tunicle).Perhaps, can, after pull and stretch processing, implement the rear coating processing (application tunicle) of the above-mentioned coating that radiance is high.Thus, can increase the transferring heat transmitted by radiation as radiator.If this precoating is processed before pull and stretch processing and in advance the feed metal thin plate implemented, also play the effect of the lubricant in pull and stretch processing.
This radiance ε is the ratio of thermal-radiating theoretical value with respect to actual object (as the thermal radiation of the black matrix of desirable thermal radiator), actual mensuration can adopt the method for putting down in writing in TOHKEMY 2002-234460 communique, and the portable type radiance determinator that can also sell by market is measured.
(to the assembling of Vehicular lamp)
Radiator of the present invention can similarly carry out with the assembling of general up to now radiator to the assembling of vehicle-mounted LED lamp etc., and this point is also advantage.Usually, vehicle-mounted LED lamp (lamps apparatus for vehicle) comprising: the LED substrate as the LED element of light source is installed; The reflector that will reflect towards irradiation direction the place ahead from the light of LED; Surround above-mentioned LED substrate and the housing of reflector; The outer lens formed by transparent material that the front end of the opening of housing is sealed; Be configured to the radiator contacted with the LED substrate heat.Described reflector is shaped by resin material, possesses near the reflecting surface of the focal parabola of the tool system LED on the LED substrate.At this, radiator of the present invention is as above-mentioned LED substrate or be configured to the radiator contacted with the LED substrate heat.In this case, as vehicle-mounted LED lamp, radiator of the present invention is not that existing radiator carries out to air the heat radiation that the hot convection current of passing through air of transmitting is carried out like that, but the heat radiation of being undertaken by the radiation of heat is main body, and this point and existing radiator differ greatly.
Embodiment
Radiator to each shape of the comparative example of the conventional example of the first variation of Fig. 6, Fig. 2 of being equivalent to above-mentioned Fig. 1, Figure 47, Figure 50 carries out Practical manufacturing, and assembling LED element, applies electric current and makes the LED element luminous, measures afterwards the temperature of LED element.The results are shown in table 1.
The radiator of each shape of the comparative example of the first variation of above-mentioned Fig. 2, the conventional example of Figure 47, Figure 50 is by machinings such as cut, and the extruded bars manufacture that is aluminium from 1100 of the JIS of raw material forms.With respect to the radiator of the example of Fig. 6 of above-mentioned Fig. 1, by drawing, the end Bending Processing that is the aluminium cold-reduced sheet by 1100 of JIS becomes radiating fin manufacture.
Each example is all identical is, the size of the rectangular shape of substrate is the 100mm(z direction) * the 100mm(x direction) * thickness of slab 2mm, the length of the z direction that the rectangular shape of radiating fin is 70mm(tabular side) * height of the y direction of 30mm(tabular side) * thickness of slab 2mm.In the radiating fin the be parallel to each other interval each other of example, left and right sides 103 and 103, upper and lower sides 104 and 104 be spaced apart 80mm above (apart from the distance at LED element center for more than 35mm).The adjacent radiating fin of conventional example, comparative example each other be spaced apart 10mm.In addition, each example is all identical, and the cation that is coated with the black of selling in market in the surface electrical deposition is resin coating.When the portable type radiance determinator that emissivity is now sold when the market by the exploitation of universe aeronautical research Development institution is measured, each example is all 0.85 mutually.
Each example is all identical, and after the LED element that sell in assembling market on substrate, the electric current that applies 3.7V, 0.85A from DC power supply makes the LED element luminous.Now, temperature by thermocouple to the LED element is monitored, and radiator is airtight and be placed in the wooden cylindrical shell of 300mm * 300mm that closing of the convection current that there is no air of vehicle-mounted LED lamp simulated in space * 300mm, make the LED element luminous in the interior atmosphere of 20 ℃.Then, after certain hour, instrumentation does not rise or descends and becomes the temperature of stable state.Instrumentation all carries out 5 times in each example, obtains its mean temperature and is estimated.
As shown in table 1 such, even can confirm to be equivalent to Fig. 6 of above-mentioned Fig. 1, the example 1,2 of the first variation that is equivalent to Fig. 2 is closed space in the convection current that there is no air of vehicle-mounted LED lamp, described below 100 ℃, the extremely low temperature below 42 ℃ of the allowable temperature exemplified that the luminous efficiency that do not make element of also can remaining the LED component temperature while stablizing reduces, have the good heat dispersion (cooling performance) that the radiation by heat obtains.In addition, the example 1 of the Fig. 6 that is 4 with the sheet number of fin is compared, and the sheet number of fin is how to the certain excellent radiation performance of example 2 of Fig. 2 of 8 of the preferred upper limit, but weight becomes weight, and on the radiating efficiency this point, difference is little.
On the other hand, can confirm in the radiator of the comparative example of Figure 47 and similar conventional example 1,2, Figure 50, although the LED component temperature while stablizing is that allowable temperature is below 100 ℃, but higher than example temperature, the convection current that there is no air of vehicle-mounted LED lamp close space, the heat dispersion (cooling performance) that the radiation by heat obtains is poor.It should be noted that, when above-mentioned a series of test does not consider that imagination is equipped on actual car from the heat input of engine, Re Jiao Change device, various electric equipments, the heat input that direct sunlight produces etc.Therefore, think that the LED component temperature is lower than the LED component temperature in actual vehicle LED (real vehicle carries LED).But as the performance of radiator comparatively speaking above-mentioned a series of test, has sufficient precision and reproducibility.
According to the above fact, confirmed the critical meaning of the regulation of the sheet number of especially radiating fin of radiator of the present invention and configuration.
[table 1]
Above, radiator of the present invention is that the heat radiation of being undertaken by the radiation of the heat from radiating surfaces such as described heat radiation sides is main body, is best suited for almost the there is no cross-ventilation radiator of narrow usage space (using, arrange environment) of (almost can't expect the heat radiation of being undertaken by the convection current of air).Therefore, can in the thermal component towards Vehicular illumination lamps such as vehicle-mounted LED lamps, use.
(the second execution mode)
Fig. 8 means the LED illumination radiator 201 of the second execution mode.This LED illumination is made by tabular aluminium of radiator 201, it is characterized in that, this LED illumination is carried out Bending Processing with radiator 201 by the blank 241 to aluminium and is shaped integratedly, horizontal face 211 and vertical front side section 221,222 form by replacing continuous stair-stepping baseplate part 202, and are formed with the department of assembly 203 of LED element on the surface of the horizontal face 211 of baseplate part 202 and/or vertical front side section 221,222.Wherein, horizontal face 211 forms assembling face of the present invention, and vertical front side section 221,222 forms the first fin section of the present invention, and vertical side face 231～236 described later forms the second fin section of the present invention.
Particularly, as shown in Figure 8, radiator 201 consists of baseplate part 202, and this baseplate part 202 is formed by the tabular aluminium with fixing equal wall thickness (comprising its alloy) material, and integral body has stair-stepping shape.; this baseplate part 202 forms shape (structure) as follows: from the top of ladder, with the order of vertical front side section 221 with identical rectangular shape, horizontal face 211, vertical front side section 222, make rectangular horizontal face and vertical front side section mutually replace continuous and integrated.Surface central authorities at the horizontal face 211 of this baseplate part 202 are provided with the LED element department of assembly 203 bloated.
And, in the end of the both sides of this baseplate part 202 of this radiator 201, also be provided with integratedly the side plate vertical with this baseplate part 202 204.That is, in the both sides of the vertical front side section 221 on the top of baseplate part 202, have respectively with this face portion 221 at right angles and towards its rear the vertical side of configuration face 231 and vertical side face 232 continuously.In addition, in the end of the both sides of the horizontal face 211 of baseplate part 202, have respectively and this horizontal face 211 vertical side of configuration face 233 and vertical side face 234 continuously at right angles and below it.And, in the both sides of the vertical front side section 222 of the bottom of baseplate part 202, have respectively with this face portion 222 at right angles and towards its place ahead the vertical side of configuration face 235 and vertical side face 236 continuously.
Although the baseplate part 202 of above-mentioned formation radiator 201 and the wall thickness of side plate 204 also depend on whole size etc., from its rigidity, thermal diffusivity and light-weighted viewpoint, usually are preferably 0.5～5mm.
It should be noted that, as aluminium, be not particularly limited, but preferably use pyroconductivity and the fine aluminium of the JIS1000 that has excellent moldability system, the aluminium alloy of JIS3000 system, the aluminium alloy of JIS5000 system etc.
Below, based on Fig. 9, the manufacture method of the radiator 201 of this second execution mode is described.
At first, as shown in the upper figure of Fig. 9, the tabular aluminium coiled material 240 of manufacturing by rolling is carried out to stamping-out processing, thereby obtain being equivalent to 1 blank 241 of the flat shape of the expanded view corresponding with the three-dimensional shape of the radiator 201 of Fig. 8.This blank 241 is as figure below of Fig. 9, and integral body has rectangular shape, at each two positions of its both sides, amount to four positions and have notch 242.This notch 242 is positioned at the position of the length of blank 241 being carried out to trisection, is the band shape of extending abreast with the length of regulation to center side from the end of the long side of blank 241.It should be noted that, also can replace aluminium coiled material 240, and use the sheet material of being manufactured by rolling.
Then, by impression, process, at the surperficial middle position of this blank 241, form the rectangular-shaped LED element department of assembly 203 bloated upward.
Then, carry out the Bending Processing of the each several part of this blank 241.In figure below of Fig. 9, to the identical symbol of symbol that the plane of blank 241 is divided and record is corresponding with the title of the each several part of the three-dimensional shape of the formation radiator 201 of Fig. 8.The 202nd, baseplate part, the 204th, side plate.Dotted line part is the boundary line of continuous each several part, the sweep (folding line) while meaning to carry out Bending Processing.
At this, at first, by the at right angles bending upward centered by the sweep 243 that becomes 221 faces and the boundary line of 211 faces integratedly of 221 faces of blank 241 and 231 faces, 232 faces, and, by the bending at right angles downwards centered by the sweep 243 that becomes 222 faces and the boundary line of 211 faces integratedly of 222 faces and 235 faces, 236 faces, thus the vertical front side section 222 that is shaped by the horizontal face 211 of the vertical front side section 221 on the top of Fig. 8, pars intermedia and bottom forms stepped alternately continuous baseplate part 202.Then, 231 faces and 232 faces be take become centered by the sweep 243 of the boundary line separately of they and 221 faces rearward (in Fig. 9 as below) at right angles bending, thereby be shaped at continuous vertical side facial 231 and the vertical side face 232 of the both side ends of the vertical front side section 221 of Fig. 8 and this vertical front side section 221.Then, 235 faces and 236 faces be take become centered by the sweep 243 of the boundary line separately of they and 222 faces forwards (in Fig. 9 as below) at right angles bending, thereby be shaped at continuous vertical side facial 235 and the vertical side face 236 of the both side ends of the vertical front side section 222 of Fig. 8 and this vertical front side section 222.And, by 233 faces and 234 faces by become they with the sweep 243 of the boundary line separately of 211 faces centered by bending at right angles downwards, thereby be shaped at the both side ends of the horizontal face 211 of Fig. 8 and continuous vertical side facial 233 and the vertical side face 234 of this horizontal facial 211.
By the Bending Processing of above blank 241, the LED illumination making of radiator 201 that completes the execution mode of Fig. 8.It should be noted that, the order of the processing of the each several part in the Bending Processing of the blank 241 of the making use of the radiator 201 of present embodiment is not particularly limited as above-mentioned method.The order of suitably replacing processing can be carried out the making of this radiator 201 too.
Like this, it is raw material that the LED of the execution mode of Fig. 8 illumination take with radiator 201 aluminium sheet obtained by plastic workings such as rollings, and only it is carried out to stamping-out processing, impression processing and Bending Processing, just can easily make, and, owing to being structure by light sheet combination, therefore light weight extremely, and keep sufficient rigidity.And, with the radiator of existing die casting system, compare, can significantly reduce its cost of manufacture.
Then, adopting the execution mode shown in Fig. 8 is example, by Figure 10, in the space of the sealing that radiator 201 of the present invention is arranged on to the convection current that there is no air and principle, the effect of the heat radiation while carrying out the LED illumination describe.At this, mean the radiation direction from the heat Q of each several part with arrow, and the enclosure space around meaning with S.
At first, when the LED element that makes assembling in the LED of horizontal face 211 element department of assembly 203 is luminous, follow in this, the heat that the LED element sends conducts to horizontal face 211 by LED element department of assembly 203.And then, be transmitted to the heat of horizontal face 211 to vertical front side section 221,222,233,234 conduction of vertical side face.And the heat Q that is transmitted to horizontal face 211 is from the table back side of horizontal face 211 along its right angle orientation (above-below direction of figure omits from the arrow of the heat Q at the back side) peripherad enclosure space (heat-dissipating space) S radiation.And the heat Q that is delivered to vertical front side section 221,222 is from the table back side of vertical front side section 221,222 to this space S radiation of their right angle orientation (fore-and-aft direction of figure omits from the arrow of the heat Q at 222 back sides).And the heat Q that is transmitted to vertical side face 233,234 is from the surface of vertical side face 233,234 to this space S radiation of right angle orientation separately (right side of figure and left to, omit from the arrow of the heat Q at the back side).
On the other hand, a part of heat Q that is transmitted to vertical front side section 221 is to 231,232 conduction of vertical side face, and from the table back side of this both sides face respectively to this space S radiation around right angle orientation (right side of figure and left to).In addition, a part of heat Q that is transmitted to vertical front side section 222 is to 235,236 conduction of vertical side face, and from the table back side of this both sides face respectively to this space S radiation around right angle orientation (right side of figure and left to).
It should be noted that, in vertical side face 231～236,231 and 232,233 and 234 and 235 and 236 face mutually, therefore with horizontal face 211 or vertical front side section 221,222, compare, and the heat radiation of being undertaken by radiation is few.This be due to, for example, with regard to 231 and 232, the heat Q on the surface from 231 (the right surface of figure) and 232 surface (left surface of figure) is to the direct radiation of space S around right angle orientation separately and fully heat radiation, and on the other hand, the back side from 231 (left surface of figure) is to the heat Q of right angle orientation radiation with from 232 the back side (the right surface of figure) to the two intersection of heat Q of right angle orientation radiation, absorb each other heat, hinder the heat radiation of peripherad space S.
Like this, the known radiator due to Fig. 8 by horizontal face 211 and vertical front side section 221,222 alternately continuous stair-stepping baseplate part 202 form, and the both side ends at baseplate part 202 has vertical side face 231～236, even therefore the efficiency of heat radiation by the radiation domination be difficult to produce the heat-dissipating space of sealing of convection current, with respect to the direction of x, y, z, be that the projected area of three-dimensional direction is also very large, therefore radiation efficiency is high, has good thermal diffusivity.
Then, to global shape, the first variation of second execution mode identical with the second execution mode of Fig. 8 describes.Although the radiator self of the first variation of this second execution mode is not shown, but only making stair-stepping baseplate part 202(horizontal face 211, vertical front side section 221 and the vertical front side section 222 of Fig. 8) wall thickness of the vertical side face (231,232,233,234,235,236) that arranges from the end of both sides at this baseplate part 202 is different, has in addition and the identical shape of the radiator of Fig. 8.
Figure 11 of form based on meaning the blank after impression processing, specifically described the first variation of this second execution mode.
Manufacture method to this blank 241 is narrated: prepare the two kinds of different tabular aluminium coiled materials of wall thickness manufacture by rolling, and will carry out respectively stamping-out processing or cut off processing and 2 plates welding of thick 1 plate of the wall thickness that obtains and wall thickness and make them integrated them.244 mean welding seam part.And, run through the notch 242 that the band shape of extending abreast with the length of regulation to center side from end is set in the position of its length being carried out to trisection.
By this blank 241 is carried out to the Bending Processing illustrated in the second execution mode, can easily produce thus the radiator 201 of the first variation of the second execution mode.The radiator 201 of the first variation of the second execution mode is characterised in that, although be the three-dimensional shape identical with the radiator shown in Fig. 8, form stair-stepping baseplate part 202, be that the wall ratio side plate 204 of vertical front side section 221, the horizontal face 211 of Figure 11 and vertical front side section 222 is that the wall thickness of vertical side face 231,232,233,234,235 and 236 is thick.Particularly, the wall thickness of preferable substrate section 202 is 0.5～5mm, and the wall thickness of side plate 204 is 0.25～2.5mm.
The first variation according to this second execution mode, with the radiator of the second execution mode shown in Fig. 8, compare, can further improve the rigidity as the stair-stepping baseplate part 202 of the skeleton of radiator, and maintaining heat conductivity higher simultaneously, its thermal diffusivity can further be improved.
Then, Figure 12 of the form of the blank based on after processing with above-mentioned similarly expression impression, to global shape, the second variation of second execution mode identical with the second execution mode of Fig. 8 is specifically described.These blank 241 integral body have rectangular shape, at each two positions of its both sides, add up to four positions to there is notch 242, and this blank 241 is blanks that the side plate 204 of the wall thickness of the baseplate part 202 thick by the wall thickness of central portion and both sides forms, as the shape of blank, it is the identical shape of the shape with above-mentioned middle explanation.But this blank 241 is welded from the plate that two kinds different from wall thickness tabular aluminium coiled materials are obtained and integrated blank is different.
That is the aluminium extrusion material of the side plate 204 of the baseplate part 202 that, this blank 241 is thick by the wall thickness with central portion and the wall thickness of both sides forms.In order to manufacture blank 241, as long as use the mould suitable with its cross sectional shape to carry out extrusion process, notch 242 is set afterwards and gets final product.In addition, by this blank 241 is carried out to the Bending Processing illustrated in the second execution mode, thereby can easily produce equally the radiator 201 of the second variation of the second execution mode.
The radiator of the second variation of this second execution mode is compared with the radiator of the second execution mode shown in Fig. 8, can further improve the rigidity of the stair-stepping baseplate part 202 of the skeleton that becomes radiator 201, and maintaining heat conductivity higher simultaneously, can make its thermal diffusivity further improve.And, in addition, need not carry out stamping-out processing or welding, just can manufacture the different blank 241 in the Width wall thickness of homogeneous and one by extrusion process, so the production process of radiator compares with the production process of the radiator shown in Fig. 9, become simple.
The radiator of Fig. 8 means the form of basic global shape, and the second execution mode is not defined in this.For example, the radiator of Fig. 8 has the stepped of 1 rank that consist of upper and lower vertical front side section 221,222, horizontal between them face 211 three of forming, but, in order further to increase the projected area to heat-dissipating space, more than it can also being configured to four sides, making exponent number is more than 2 rank.In addition, in Fig. 8, forming stair-stepping horizontal face 211 and vertical front side section 221,222 is all equal length and the identical rectangle (rectangle) of width, but also can make different rectangles replace continuous shape for the length to them and width are changed, can think the width, depth on ladder (1 rank) and different shape highly respectively.And ladder can be also the erose ladder to Width (left and right) changing of the relative positions according to its step.
In addition, in Fig. 8, the both sides that are illustrated in vertical front side section 221, horizontal face 211 and vertical front side section 222 possess respectively the structure of vertical side face 231,232, vertical side face 233,234 and vertical side face 235,236, but also can omit the vertical side face 231,232 of the both side ends that wherein is positioned at vertical side face 221,222 and the side surface part of a whole or side of 235,236.
Then, based on Figure 13, to global shape, the 3rd variation of second execution mode different from the second enforcement side of Fig. 8 describes.
At this, the LED illumination of the 3rd variation of the second execution mode consists of baseplate part 202 equally with the second execution mode of radiator and Fig. 8, this baseplate part 202 is formed by the tabular aluminium with fixing equal wall thickness (comprising its alloy) material, and integral body has stair-stepping shape.With the form difference of Fig. 8, be, at first, as the structure of baseplate part 202, also there is horizontal face 212, this horizontal face 212 at right angles configures towards its rear continuously on the top of vertical front side section 221 and its, thereby baseplate part 202 is the stepped of second order.
Secondly, in the radiator of the 3rd variation of the second execution mode, structure and Fig. 8 of the side plate 204 arranged in the end of the both sides of baseplate part 202 differ greatly.There is the vertical side face 231 and 232 that at right angles below it, is configured to continuously bottom (lower end position of vertical front side section 222) with it in the end of the both sides of horizontal face 212.In addition, there is the vertical side face 2331 and 2332 of (2/3rds width) midway that at right angles towards its place ahead, is configured to continuously the whole width of horizontal face 211 with it in the end of the both sides of vertical front side section 221.And, in the end of the both sides of horizontal face 211, have and its vertical side of configuration face 2333 and 2334 continuously at right angles and below it.
In addition, position in the upper and lower separately of vertical side face 231 and 232 possesses the flange part 251 and 252 of coincidence, and it is outstanding and external and cover the part (rear portion side) on the surface of vertical side face 2331 and 2332 and 2333 and 2334 towards the place ahead that this overlaps flange part 251 and 252.And, possessing in the position of the central portion separately of vertical side face 2333 and 2334 flange part 253 of coincidence, it is outstanding and external and cover the part (rear portion side) on the surface of vertical side face 235 and 236 towards the place ahead that this overlaps flange part 253.
Below, based on Figure 14, the manufacture method of the radiator 201 of the 3rd variation of the second above-mentioned execution mode is described.
At first, as shown in the upper figure of Figure 14, the tabular aluminium coiled material 240 of manufacturing by rolling is carried out to stamping-out processing, obtain being equivalent to 1 blank 241 of the flat shape of the expanded view corresponding with the three-dimensional shape of the radiator 201 of Figure 13.This blank 241 is as figure below of Figure 14, and integral body has T word shape, is provided with around the notch 2421～2423 that adds up to six positions.That is, there is respectively the notch 2421 at a position in two bottoms (both sides, front of figure) of its head 241a, and, the notch 2422,2423 at two positions there is respectively in the both sides of its main part 241b.Notch 2421 forms the key shape on 2 rank, and notch 2422 forms band shape, and notch 2423 forms the shape of the key shape on 1 rank.
Then, by impression, process, at the surperficial middle position of this blank 241, form the rectangular-shaped LED element department of assembly 203 bloated upward.
Then, carry out the Bending Processing of each one of this blank 241.In figure below of Figure 14, to the identical symbol of symbol that the plane of blank 241 is divided and record is corresponding with the title of the each several part of the three-dimensional shape of the formation radiator 201 of Figure 13.The 202nd, baseplate part, the 204th, side plate.Dotted line part is the boundary line of continuous each several part, the sweep (folding line) while meaning to carry out Bending Processing.
At this, at first, by the at right angles bending upward centered by the sweep 243 that becomes 221 faces and the boundary line of 211 faces integratedly of 221 faces and 2331 faces, 2332 faces, 212 faces of blank 241,231 faces and 232 faces.And, by the at right angles bending downwards centered by the sweep 243 that becomes 222 faces and the boundary line of 211 faces integratedly of 222 faces and 235 faces, 236 faces.Then, 212 faces and 231 faces, 232 faces be take integratedly become centered by the sweep 243 of 212 faces and the boundary line of 221 faces rearward (in Figure 14 as below) at right angles bending.Like this, from the top of Figure 13 with the order of horizontal face 212, vertical front side section 221, horizontal face 211 and the vertical front side section 222 stepped continuous baseplate part 202 that replaces that is shaped.
After the described stair-stepping baseplate part 202 that is shaped, by 235 faces and 236 faces take become they with the sweep 243 of the boundary line separately of 221 faces centered by forwards (in Figure 14 as above) rectangular bending, thereby be shaped at continuous vertical side facial 235 and the vertical side face 236 of the both side ends of the vertical front side section 222 of Figure 13 and vertical front side section 222.Then, by 2333 faces and 2334 faces by become they with the sweep 243 of the boundary line separately of 211 faces centered by bending at right angles downwards, thereby be shaped at the both side ends of the horizontal face 211 of Figure 13 and continuous vertical side facial 2333 and the vertical side face 2334 of this horizontal facial 211.
By this, be shaped, the coincidence flange part 253 of 2333 faces and 2334 faces is facial with 235 and surfaces 236 faces are overlapping and engage respectively.That is, as shown in Figure 13, the coincidence flange part 253 of vertical side face 2333 and vertical side face 2334 covers the part (rear portion side) of vertical side face 235 and vertical side face 236 engage with them, and this bonding part becomes double-decker.
Then, 2331 faces, 2332 faces be take become centered by the sweep 243 of the boundary line separately of they and 221 faces forwards (in Figure 14 as above) at right angles bending, thereby be shaped at continuous vertical side face 2331, the vertical side face 2332 of the both side ends of the vertical front side section 221 of Figure 13 and vertical front side section 221.
Then, by 231 faces and 232 faces by become they with the sweep 243 of the boundary line separately of 212 faces centered by bending at right angles downwards, thereby be shaped at the both side ends of the horizontal face 212 of Figure 13 and continuous vertical side facial 231 and the vertical side face 232 of horizontal facial 212.
By this shaping, the coincidence flange part 251 of 231 faces and 232 faces overlaps with the state joined with the surface of 2331 faces and 2332 faces respectively, and the coincidence flange part 252 of this 231 face and this 232 face overlaps with the state joined with the surface of 2333 faces and 2334 faces respectively.; as shown in Figure 13; the coincidence flange part 251 on the top of vertical side face 231 and vertical side face 232 covers the part (rear portion side) of vertical side face 2331 and vertical side face 2332 and overlap with them; the coincidence flange part 252 of the bottom of this vertical side face 231 and this vertical side face 232 covers the part (rear portion side) of vertical side face 2333 and vertical side face 2334 and overlap with them, and the part of above-mentioned coincidence all becomes double-decker.
By the Bending Processing of above blank 241, complete the making of radiator 201 for LED illumination of the 3rd variation of the second execution mode of Figure 13.In the order of the processing of the each several part of the Bending Processing of the blank 241 of the making for this radiator 201, with the second execution mode of Fig. 8, be not particularly limited equally as above-mentioned method.But, due to the situation of the 3rd variation of the second execution mode than the structure complicated of Fig. 8, therefore should be noted that the bending with the vertical side face that overlaps flange part the fixing processing sequence such as carries out after the processing of the vertical side face of an engaged side, in order to avoid each several part is interfered mutually during bending.
The 3rd variation according to this second execution mode, with the radiator of the second execution mode shown in Fig. 8, compare, by appending horizontal face 212, vertical side face 231 and 232, vertical side face 2331 and 2332 etc. or increasing their area, thereby the projected area with respect to three-dimensional direction further increases, therefore the radiation efficiency of radiator is higher, has better thermal diffusivity.In addition, owing on vertical side face 231 and 232,2333 and 2334, forming respectively and overlapping flange part 251～253, thereby be vertical side face 2331 and 2332,2333 and 2334,235 and 236 structures that overlap and engage, are connected with other, therefore the rapid underground heat of heat produced from the LED element be transmitted to separation each vertical side face (fin) end and carry out radiation, thus, given play to higher thermal diffusivity.And the part of this coincidence becomes double-deck plate structure by the coincidence of above-mentioned vertical side face, therefore with the structure of a slice of Fig. 8, to compare, the rigidity of radiator increases, and can realize the raising of its intensity, durability and stability.
It should be noted that, in the 3rd variation of the second execution mode, each other via the example that overlaps flange part and overlap, but being not limited to this for the vertical side face, can be also the horizontal face of vertical side section and baseplate part 202 and/or the structure that vertical front side section overlaps.
In addition, vertical side face double-decker section each other in the 3rd variation of the second execution mode also can further by screw fastening, link or the joint method such as tightening of rivet link, the fastening link of ca(u)lk, welding, soldering, by the combination integratedly of double-deck material, can improve significantly thus the rigidity of radiator.
(the 3rd execution mode)
Figure 15 means the LED illumination radiator 301 of the 3rd execution mode.This LED illumination is formed by aluminium sheet 302 with radiator 301, it is characterized in that, has horizontal face 311,312 and vertical front side section 321,322 and replaces continuous steppedly, on the surface of horizontal face and/or vertical front side section, is equipped with LED element 300.Wherein, horizontal face 312 forms assembling face of the present invention, and vertical front side section 321,322 forms the first fin section of the present invention, and vertical side face 331～338 described later forms the second fin section of the present invention.
Particularly, as shown in figure 15, the radiator 301 of the 3rd execution mode is formed by the aluminium with fixing wall thickness (comprising its alloy) plate 302, and integral body has stair-stepping shape.That is, in situation in the drawings, be the stepped of 2 rank, by aluminium sheet 302, formed, and whole basic configuration has stepped.; in situation in the drawings; be the stepped of 2 rank; and, from the top of ladder, with the order of its horizontal face 311, vertical front side section 321, horizontal face 312, vertical front side section 322, form mutually rectangular horizontal face and vertical front side section alternately continuously and the shape (structure) formed.
Above-mentioned horizontal face 311,312 and vertical front side section 321,322 are all rectangle, and this rectangle be take the length identical with the width that forms stair-stepping aluminium sheet 302 as long limit, and to take the width that the length of aluminium sheet is carried out to 4 deciles be minor face.
The 300th, at the LED element of the central portion of horizontal face 312 assembling.
And, in horizontal face and vertical front side section, the both side ends of horizontal face 312 and vertical front side section 321 also possess with they at right angles, the vertical side face 331,332 that vertically configures.Vertical side face the 331, the 332nd, the width of described horizontal face 311,312 and vertical front side section 321,322 of take is square on one side.
Then, to having that so stair-stepping radiator 301 is arranged on the space of the convection current that there is no air and principle, the effect of carrying out the heat radiation in LED when illumination narrated.When the LED element 300 that makes assembling on horizontal face 312 is luminous, to follow in this, the heat that LED element 300 sends conducts to horizontal face 312 by the department of assembly of LED element 300.And then, be transmitted to the heat of horizontal face 312 to vertical front side section 321, vertical front side section 322,331,332 conduction of vertical side face.Like this, the heat that is transmitted to horizontal face 312 to the continuous vertical front side section more than 2 or the conduction of vertical side face of horizontal face 312.And, be transmitted to the heat Q of horizontal face 312 also from whole enclosure space (heat-dissipating space) the S radiation on every side towards its right angle orientation (above-below direction of Figure 15) of the table back of the body of this horizontal face 312, the heat Q that is transmitted to vertical front side section 321 is from whole this space S radiation towards its right angle orientation (left and right directions of Figure 15) of the table back of the body of this vertical front side section 321, the heat Q that is delivered to vertical side face 331,332 from whole of vertical side face 331,332 respectively to their this space S radiation of right angle orientation (right side of Figure 16 and left to).It should be noted that, from the side towards LED element 300 (left surface of Figure 15) of vertical side face 331,332 the side towards LED element 300 (the right surface of Figure 15), also to the left and right direction of figure, dispelled the heat respectively, but from 331 heat radiations to left by 332 right Surface absorption, from 332 to right-hand heat radiation by 331 absorptions, the heat radiation of therefore being undertaken by the radiation from above-mentioned two sides is few.
In addition, a part of heat Q that is transmitted to vertical front side section 321 is to 311 conduction of horizontal face, and from whole of the table back of the body of horizontal face 311 respectively to this space S radiation around right angle orientation (Figure 15 and lower direction).It should be noted that, be delivered to the high low side's conduction of a direction from the heat level mutually of 312,321,322,311,331 and 332 heat.
Like this, as shown in figure 15, known radiator has stepped, and also possesses the vertical side face in the both sides that form this stair-stepping horizontal face, vertical front side section, even in the heat-dissipating space that there is no cross-ventilated sealing that this radiator is arranged by radiation in the efficiency of its heat radiation, with respect to the x, y, z direction, be that the projected area of three-dimensional direction is also very large, so radiation efficiency is high, has good thermal diffusivity.In addition, because the projected area in this radiator does not repeat on the radiation direction to heat-dissipating space, therefore the radiating efficiency of every heat radiation unit are is good, can form simple structure.In addition, by having from being equipped with the continuous vertical front side section more than 2 or the vertical side face of horizontal face 312 of LED element, the heat that the LED element sends thus conducts to multiple directions from the LED fitting surface, therefore heat is diffused rapidly, and then promote the radiation from face separately, therefore there is good thermal diffusivity.
Then, the manufacture method of the radiator of the shape shown in Figure 15 described.
At first, take fine aluminium or aluminium alloy as raw material, by processing such as rollings, manufacture the pure aluminum plate of thickness of regulation or aluminium alloy plate (by them in the present invention referred to as aluminium sheet).Four times of the size of the rectangular minor face 311(312 that the length L of the aluminium sheet of manufacturing is Figure 15,321 and 322 all identical), its width W is for adding that on the size on this rectangular long limit 331(332 is too) size that obtains of the size on foursquare one side.
Then, the aluminium sheet that to process the size of the L * W manufactured by rolling take in four rectangles of on its length direction quartering except since the 3rd an of end first, the part of the both sides of second, the 4th is object, to the 331(332 that is equivalent to Figure 15 too) the Length Quantity of size on foursquare one side cut off and removed.Cut off processing by this, obtain the aluminium sheet 302 of Figure 15, this aluminium sheet 302 is by three short rectangles of the width corresponding with 311,321 and 322 (long limit) and add that on 312 width the rectangle of length of the width (total width) on 331,332 1 limit forms.
By the width of the horizontal face 311 of this aluminium sheet 302, short rectangular segment is with respect to rectangular segment at right angles bending centered by their boundary line of vertical front side section 321, and, by this rectangular segment of horizontal face 312 with respect to the rectangular segment of vertical front side section 321 centered by their boundary line to a side rectangular bending contrary with horizontal face 311, and, this rectangular segment of horizontal face 312 by this rectangular segment of vertical front side section 322 after with respect to bending centered by their boundary line further to the rectangular bending of opposition side.Thus, can form the stairstepping as basic configuration.
And, the square part that finally, will be positioned at the vertical side face 331 of Width both sides of rectangular segment of the long horizontal face 312+ vertical side face 331+ vertical side face 332 of width and vertical side face 332 with respect to the rectangular segment of horizontal face 312 respectively centered by the boundary line of they and horizontal face 312 and respectively to the rectangular bending of face side of vertical front side section 321.Like this, by take aluminium sheet 302 as raw material and adopting, cut off and the so fairly simple processing method of bending, can easily produce the radiator of the present invention 301 shown in Figure 15.
As the method for manufacturing aluminium sheet 302, enumerate rolling and be illustrated, but be not limited to this, also can use extruding to wait other processing method.
The radiator 301 of Figure 15 means the execution mode of basic global shape, and the 3rd execution mode is not defined in this.For example, the radiator of Figure 15 has the stepped of 2 rank, but, in order further to increase the projected area to heat-dissipating space, also can make this exponent number is more than 3 rank.In addition, in Figure 15, the stair-stepping horizontal face 311,312 and the vertical front side section 321,322 that form 2 rank are all equal length and the identical rectangle of width, but also can make different rectangles replace continuous shape for the length to them and width are changed, can think the width, depth on ladder (1 rank) and different shape highly respectively.And ladder can be also the erose ladder to Width (left and right) changing of the relative positions according to its step.
In addition, in Figure 15, the both sides that are illustrated in horizontal face 312 and vertical front side section 321 possess the situation of vertical side face 331,332, but this vertical side face does not need to be positioned at these stair-stepping both sides, can only be positioned at a side, and be not limited to the one or both sides of horizontal face 312 and vertical front side section 321, also can have in the one or both sides of horizontal face 312 and vertical front side section 322, horizontal face 311 and vertical front side section 321.And, this vertical side face can be in the perpendicular configuration in (or a side) end of above-mentioned horizontal face or the only either party's in vertical front side section both sides, that is, comprise such as the vertical outstanding structure in the top of the both side ends of the horizontal face 311 to Figure 15, to the vertical outstanding structure in the place ahead of the both side ends of vertical front side section 322 etc.
In addition, the vertical side face 331 of Figure 15, 332 as described above, the rectangular aluminium sheet that will consist of horizontal face 312+ vertical side face 331+ vertical side face 332 obtains to equidirectional rectangular bending, and continuous with horizontal face 312 one, and the cut-out by sheet material, bending machining can easily form, therefore preferably, but also can prepare the vertical side face 331 of split in advance, 332 plate, and with the state of the both ends arranged perpendicular of the vertical front side section 321 forming stair-stepping main body respectively with the both ends welding of vertical front side section 321 and form.
In addition, in Figure 15, the wall thickness that forms the aluminium sheet 302 of each face 311,321,312,322 is fixed, but for the horizontal face 312 of assembling LED element 300, and the wall thickness that makes this department of assembly thickening partly is effective.Figure 17 means this example, is department of assembly's sectional view of the LED element 300 of horizontal face 312.
At this, the wall thickness of the horizontal face 312 except the department of assembly of LED element 300 is identical with other face 321,312,322, but for this department of assembly, the heavy section 3121 that formation bloats the rear side of horizontal face 312 downwards.Like this, the wall thickness thickening of the department of assembly of the LED element 300 by making horizontal face 312, thus when illumination, the peripherad thinner wall section 3122 of a large amount of heats produced on horizontal face 312 is conducted rapidly, and from the whole heat-dissipating space radiation of below facing up of the table back of the body of horizontal face 312, but also simultaneously to adjacent, continuous each face 321,322,331,332 conduction of horizontal face 312, and also from these surface radiations, therefore can further improve whole radiating efficiency, if and such shape, its manufacture is also easy.
Based on Figure 18～Figure 21, the state that arranges of the situation of the headlamp that LED described above illumination is applicable to motor vehicle with radiator 301 is narrated.Figure 18 is illustrated in the stereogram of the state arranged on this headlamp, and Figure 19 means the a-a cutaway view of Figure 18, and Figure 20 means the b-b cutaway view of Figure 18, and Figure 21 means the c-c cutaway view of Figure 18.
At this, radiator 301 is formed by aluminium sheet 302, have and start stepped (2 rank) that formed in turn by vertical front side section 321, horizontal face 311, vertical front side section 322, horizontal face 312 from top, and there are respectively vertical side face 331,332 and 333,334 in the both side ends of both side ends, horizontal face 312 and the vertical front side section 322 of horizontal face 311 and vertical front side section 322.In addition, there is respectively (outstanding) the vertical side face 335,336 stretched out downwards in the both side ends of horizontal face 312, also there is (outstanding) the vertical side face 337,338 rearward stretched out respectively in the both side ends of vertical front side section 321.At this, vertical side face 331,332 forms by the part rectangular bending downwards that will extend in the both sides of horizontal face 311, become same plane with the side of housing 340, vertical side face 333 by the part that will be in vertical front side section 322 extends to both sides forward at right angles bending form, and be provided in the outside of the side of housing 340 with overlapping state.Vertical side face 335,336 by the part that will be on horizontal face 312 extends to both sides downwards at right angles bending form, in addition, vertical side face 337,338 by the part that will extend to both sides in vertical front side section 321 backward at right angles bending form.
The 300th, at the LED element that becomes light emitting source of the upper surface of upper and lower horizontal face 311,312 assembling, the 350th, the reflector (omitting in Figure 18) arranged in the inner surface side of upper and lower vertical front side section 321,322, in addition, and the 360th, outer lens.
And, this radiator 301 is so that the housing of frame shaped is located at state on stair-stepping radiator this housing 340 of packing in 340 years, it is roughly circular-arc that the upper end of the two sides of this housing 340 is, it is step-like that lower end is, and in these housing 340 front portions, have and described roughly circular-arc corresponding curved surface peristome.Fix respectively, be supported on the installation portion (not shown) of vehicle body with the vertical side face 335,336 and 337,338 of these housing 340 integrated radiators.Embed the outer lens 360 had with its transmissive glass system with shape on the curved surface peristome of housing 340.
Each outer surface of the vertical front side section 321 of radiator 301, horizontal face 311, vertical front side section 322, horizontal face 312 and the enclosure space S of interior of body are opposed.In addition, the vertical side face 331,332,335,336 of radiator and 337,338 surfaces externally and internally are also opposed with this space S.
Under such state that arranges, headlamp as motor vehicle, by LED element 300, undertaken luminous, when illumination, follow the luminous of LED element 300 and the heat that produces by radiation enclosure space (heat-dissipating space) S heat radiation around opposed from the surfaces externally and internally of the vertical side face 331～338 at the outer surface that forms stair-stepping each face 311,312,321,322 and their both ends.And the high radiator of radiation efficiency of the very large radiating surface of projected area of the three-dimensional of this heat radiation by having x, y and z axle carries out, therefore for almost not having cross-ventilated narrow space can very effectively implement heat radiation.
(the 4th execution mode)
Figure 22 means the LED illumination radiator 401 of the 4th execution mode.This LED illumination is formed by the aluminium extrusion material with radiator 401, it is characterized in that, by baseplate part 402 and fin section 403, formed, this baseplate part 402 is fixed with LED light source 400 in the face side configuration, this fin section 403 gives prominence to and the multi-disc configured in parallel in the rear side devices spaced apart of baseplate part 402, in each fin section 403, the part of the fin section 403 of at least 1 becomes the bending sheet 403b of fin section from the rectangular bending of the main body 403a of fin section, the bending sheet 403b of fin section has and the radiating surface of the radiating surface of the main body 403a of fin section and the described baseplate part radiating surface of the direction of quadrature respectively.Wherein, baseplate part 402 forms assembling face of the present invention, and fin section 403 and the main body 403a of fin section form the first fin section of the present invention, and the bending sheet 403b of fin section forms the second fin section of the present invention.
Particularly, the LED of the 4th execution mode illumination is with below radiator 401(, sometimes also referred to as radiator 401.) use the pyroconductivity such as the fine aluminium of JIS1000 system, the aluminium alloy of JIS6000 system by take and aluminium extrusion material that the aluminium that has excellent moldability carries out extrusion molding is basis, and apply the fairly simple like this processing of incision, bending and manufacture.In addition, also can manufacture with other the aluminium alloy material such as the aluminium alloy material of JIS5000 system.It should be noted that, manufacture method is narrated in the back.
As shown in figure 22, the radiator 401 of the 4th execution mode for example consists of baseplate part 402 and fin section 403, this baseplate part 402 is in face side (in Figure 22, at downside, meaning) configuration is fixed with LED light source 400, and this fin section 403 is outstanding and multi-disc configured in parallel in the rear side devices spaced apart of this baseplate part 402.In above-mentioned fin section 403, the part of the fin section 403 of at least 1 becomes the bending sheet 403b of fin section from the rectangular bending of the main body 403a of fin section.It should be noted that, described LED light source 400 by will be for example a plurality of light-emitting diodes (LED) element be installed on to take on the substrate that aluminium alloy is matrix and form.
The bending sheet 403b of this fin section has and the radiating surface of the radiating surface of the main body 403a of fin section and baseplate part 402 radiating surface of the direction of quadrature respectively.That is, the radiating surface of the radiating surface of the radiating surface of baseplate part 402, the main body 403a of fin section, the bending sheet 403b of fin section becomes mutually orthogonal respectively towards the radiating surface of different directions (y direction of principal axis, x direction of principal axis, z direction of principal axis).
Vertical view, front view and the end view of the radiator 401 of the 4th execution mode shown in Figure 23, the vertical view of existing radiator 4 shown in Figure 49, front view and end view.Known in the radiator 401 shown in Figure 23, can confirm that vertical view, front view, end view can both guarantee sufficient projected area, but, in the radiator 4 shown in Figure 49, only front view can't be guaranteed sufficient projected area.
In the 4th execution mode shown in Figure 22,4 fin sections 403 are outstanding abreast in the rear side devices spaced apart of baseplate part 402, in above-mentioned 4 fin sections 403, the both ends of the fin section 403 that both sides are 2 from the main body 403a of fin section respectively towards the rectangular bending of both side edges direction of baseplate part 402 and form the bending sheet 403b of fin section.
Sheet number and the shape of above-mentioned fin section 403 do not need with the execution mode shown in Figure 22 same.The sheet number of fin section 403 is multi-disc, be more than at least 2 and get final product, in addition, in the situation that fin section 403 has more than 3, the fin section 403 that is formed with the bending sheet 403b of fin section can be the fin section 403 of 2 of both sides, for example, shown in Figure 24 (c), can in central fin section 403, form the bending sheet 403b of fin section.Exemplify the variation of the radiator 401 that forms various shapes in Figure 24.
Then, the LED illumination of the 4th execution mode illustrated simply by the manufacture method of radiator 401.As former explanation, LED of the present invention illumination be take the aluminium extrusion material with radiator 401 and is manufactured as basis, and this aluminium extrusion material carries out extrusion molding by the pyroconductivity such as the fine aluminium that uses JIS1000 system, the aluminium alloy that JIS6000 is and the raw metal that has excellent moldability and forms.
For example, in the situation that manufacture the radiator 401 shown in Figure 22, at first, the aluminium extrusion material that preparation is manufactured by extrusion molding (shape identical with radiator with the existing LED illumination shown in Figure 47), and at the both ends lower edge of the fin section 403 of the both sides of this aluminium extrusion material (position joined with baseplate part 402), be that the lower edge at 4 positions of total of fin section 403 of both sides is from the otch of both sides incision appropriate depth.Then, the position that will cut otch at the lower edge of fin section 403, respectively towards the at right angles bending of both side edges direction (lateral direction) of baseplate part 402, forms the bending sheet 403b of fin section thus.It should be noted that, lower edge do not cut otch and not the position of the centre of bending become the main body 403a of fin section.
By LED described above illumination with radiator 401 radiator 401 as the built-in-lighting of the vehicle-mounted illumination such as the headlamp of motor vehicle or building etc., but Figure 25 and Figure 26 mean the use state with radiator 401 as the LED illumination of the headlamp of motor vehicle.As shown in Figure 25 and Figure 26, the framework that this radiator 401 forms the LED illumination with its baseplate part 402 is that the state of the back part of housing 410, a part that forms housing 410 is installed.Like this, when radiator 401 is installed with the state of the housing 410 of packing into, fin section 403 gives prominence in the space of the sealing of the convection current that there is no air of the rear side of LED illumination.It should be noted that, the 420th, the outer lens with light transmission of installing in the front of LED illumination.
Like this, in the fin section 403 that makes radiator 401, when using with radiator 401 as the LED illumination under outstanding state in the space of sealing, in the space of the convection current that there is no air of heat from radiator 401 to sealing produced during LED light source 400 luminous, dispel the heat.LED illumination of the present invention uses radiator 401 as shown in vertical view, front view and the end view of Figure 23, x direction of principal axis, y direction of principal axis, z direction of principal axis can both be guaranteed sufficient projected area, even the heat radiation in the space of therefore sealing like this, also can make heat radiation effectively carry out.
(the 5th execution mode)

Above-mentioned Figure 35～Figure 38 means to process by raw material aluminium alloy sheet 601a is carried out to ripple the radiator 601 that shape is the continuous radiating fin shape of waveform 602,603, and this raw material aluminium alloy sheet 601a processes and is applied with in advance from the teeth outwards precoating processing tunicle 610 by the precoating of blacking.At this, ripple is processed as known, is the meaning of the waveform processing of smooth plate or level and smooth pipe.It is extremely thin surface coating that the precoating of blacking is processed tunicle 610, therefore only by 610 numbering, mean, but this precoating is processed tunicle 610 application in advance (covering) on the surface portion (comprising one side) of the whole surface (two sides) of aluminium alloy sheet 601a or necessity.
In the radiator 601 of Figure 35～Figure 38, waveform 602,603 all replaces connected.But the central portion of the length direction (left and right directions of figure) of the radiator 601 in Figure 37,41 waveform 602,603 is provided with difference of height, take this central portion as boundary, the level of the waveform of left and right is mutually highly different.With the design in space in the vehicle-mounted LED lamp of radiator 601 or the corresponding such difference of height etc. that arranges of arrangement in space, thereby in ripple processing, the uniform shape that the integral body that not only can make the global shape of continuous waveform 602,603 become Figure 35, Figure 36 is rectangular shape, and can form the shape of Figure 37,41 such abnormity.
The radiating fin waveform shape:
In Figure 35～Figure 38, the radiating fin=waveform 602,603 of identical width and height alternately repeats continuously with identical spacing.At this, waveform 602,603 is connected mutually, its concavo-convex towards be differ 180 degree protuberance each other or recess each other towards, more specifically, be the key element of continuous waveform or the unit of waveform, but in this manual referred to as waveform 602,603.
