Build also apply in the built-in-lighting of the other fields such as thing this vehicle LED illumination and start to LED illumination replace.
However, the luminous source of this LED illumination to be LED element very weak to hot toleration, when exceed allow temperature when, send out
Light efficiency reduces, and also there is a problem of bringing impact to its life-span.In order to solve this problem, need to make LED element light
When the peripherad space heat elimination of heat, in LED illumination, therefore possess large-scale radiator.
This LED illumination radiator adopts the radiator of the cast aluminium with aluminum or aluminum alloy as material mostly, in patent literary composition
Offer the radiator of the representational structure having disclosed in 1～4 in above-mentioned radiator.Above-mentioned radiator has joins LED light source
Put and be fixed on the baseplate part of face side, the rear side interval in this baseplate part and the fin of prominent multi-disc configured in parallel
Portion, by baseplate part and fin part are formed as radiating surface such that it is able to obtain wide swept area, it is therefore envisaged that can
Obtain certain thermal diffusivity.
However, by as shown in Figure 47 have baseplate part 2, fin part 3 LED illumination with radiator 4 be used as this machine
In the case of the heat transmission of the built-in-lighting of the vehicle-mounted illumination such as headlamp of motor-car or building etc., as shown in figure 48, this radiating
The framework that device 4 is constituted LED illumination with baseplate part 2 is that the state of the back part of housing 5 is installed, and wherein, this baseplate part 2 is by LED light
Face side is fixed in source 1 configuration, and this fin part 3 projects and multi-disc configured in parallel in the rear side interval of this baseplate part 2.
So, radiator 4 is being installed on the vehicle body of motor vehicles, the wall of building or ceiling etc. with the state loading housing 5
In the case of, prominent in the space of the closing of the convection current not having air of the rear side to LED illumination for the fin part 3.
So, using radiator in the state of projecting in the space that the fin part 3 making radiator 4 supports or opposes the closing of surface side
When 4, become to the radiating in the space of the convection current not having air of closing from the radiating that radiator 4 is carried out, put down having multi-disc
It is impossible to effectively be radiated in the radiator 4 of fin part 3 of row configuration.
That is, in the space of closing from the radiating that radiator is carried out, it is not that convection current plays dominating role, radiation becomes radiating
Center.It is therefore contemplated that arranging multi-disc fin part on a heat sink with it and so that surface area is increased, radiator might as well be made
X-axis direction, y-axis direction, z-axis direction are that the projected area in three directions all increases on improving thermal diffusivity effectively.

Means for solving the problems
In order to solve above-mentioned problem, the LED illumination radiator of the present invention is formed by aluminium, and it possesses：Assembling face, its
There is LED element surface-mounted；First fin part, it upwardly extends in the side orthogonal with respect to described assembling face；Second wing
Piece portion, it upwardly extends in the side orthogonal with respect to described assembling face, and in the side intersecting with respect to described first fin part
Upwardly extend.
In this LED illumination radiator, first and second fin part with respect to assembling LED element assembling face to orthogonal
Direction extends, and the first fin part upwardly extends in the side intersecting with respect to the second fin part, therefore, it is possible to make x-axis direction, y
Direction of principal axis, the projected area of the three-dimensional in z-axis direction all increase.Therefore, even there is no the closing of the convection current of air

Represent the first～the 6th change with the first embodiment of radiator 101 for the LED illumination of the present invention respectively with axonometric chart in 2～7
Shape example.
The basic structure of radiator：
First, basic with the identical of radiator 101 to the LED illumination of the first embodiment of the present invention in Fig. 1～7
Structure illustrates.In above-mentioned Fig. 1～7, the LED illumination radiator 101 of the present invention equally has installation LED element 100
Flat substrate 102.This substrate 102 is in the y direction of each figure（Above-below direction）Side be respectively provided with table carry on the back two faces 1021,
1022, these faces 1021,1022 extend along x, z direction of each figure.This flat substrate 102 carries on the back two faces in above-mentioned table
1021st, install on the face of either one in 1022 and support LED element 100, in Fig. 1～7, for convenience, each figure is upper
LED element 100, as the installed surface 1021 of LED element 100, is installed in the central part of the plane of installed surface 1021 in the face of side.And
And, also for convenient, using the face of the opposing party of the downside of each figure as the back side 1022.
And, the table back side 1021,1022 of substrate 102 has orthogonal with the face of either one or both（Extension side with face
Orthogonal to x, z direction of=each figure）And the y direction to each figure（Above-below direction）The flat radiating fin 103 stretching out and extending
～106.Above-mentioned flat radiating fin 103～106 is to stand up the table back side of substrate 102 towards in the form of foreign side
1021st, 1022, but be not necessarily required to make as shown in Fig. 1～7 flat radiating side and substrate 102 the table back side 1021,
1022 with 90 degree of angle.For example, radiating side can also with less than 90 degree or the angle more than 90 degree with respect to substrate
Setting is obliquely erect towards foreign side in the 102 table back side 1021,1022.But, in either case, above-mentioned tabular
Radiating fin 103～106 on material all with substrate 102 one and be continuously formed.That is, above-mentioned flat radiating fin
At least flat each table back side of piece 103～106 is formed continuously incessantly with the face 1021,1022 of substrate 102.
Therefore, form the face making the heat from LED element 100 via the LED element installation side of substrate 102（Surface）
1021 rearwardly 1022, the side of the surrounding of each radiating fin 103～106, the continuous heat transfer of the continuous heat transfer in face in thickness of slab direction
Face.And, also form the continuous radiating surface from described continuous heat-transfer area continuous radiation heat.
It should be noted that with regard to the shape of substrate 102, in Fig. 1～7, exemplifying rectangle（Square）Tabular
Or flat shape.But, the shape of this substrate 102 can according to the purposes of LED illumination radiator 101, and suitably select to justify
Shape, triangle, polygon, the flat shape such as unsetting or generally cylindrical shape, square tube shape or the three-dimensional with difference of height etc.
Shape etc..
The feature of radiating fin：
The LED illumination of the present invention mentioned above basic structure itself of radiator 101 at first sight, with Figure 47 in illustrate
The structure of existing radiator 4 seem no big difference.But, in the configuration of this flat radiating fin 103～106
Following relatively big difference point is existed with existing radiator 4 on method：Exist in the narrow space of vehicle-mounted illuminating housing or
Need consider to radiate carry out by radiation as the research of main body in closing space.
First, the LED illumination of present invention radiator 101 is premised on the basic structure of described radiator, and preferably will
The flat radiating fin 103 of the piece number of total 2～8 being respectively provided with two faces 1021,1022 of substrate 102～
106 spaced at intervals and with substrate 102 faces 1021,1022 continuously and form.
And, above-mentioned radiating fin 103～106 includes parallel state, and mutually extend towards identical direction
Fin piece number in the arbitrary section orthogonal with two faces 1021,1022 of substrate 102 be less than 2.That is, by with
In the orthogonal arbitrary section of the radiator 101 of the section in arbitrary direction in two faces 1021,1022 of substrate 102 all
For less than 2.
The meaning of the regulation of radiating fin bearing of trend：
Here, " mutually extending towards identical direction " described in the present invention comprises parallel state certainly, but not
It is only the proper parallel meaning, the angle of the radiating fin bearing of trend of tabular side each other can be slightly
Micro- difference.In the present invention, it is intended that on the arbitrary direction of the three-dimensional of radiator, all eliminating radiating fin
Excessive coincidence each other, makes material not waste, and obtains the high performance of the radiation efficiency of heat.Therefore, in this mesh of without prejudice to
Or in the range of effect, even if the angle of the radiating fin bearing of trend of tabular side each other is slightly different,
Can be regarded as and mutually be extended towards identical direction.This is radiating fin tabular side each other due to no matter
The angle of bearing of trend is slightly different, still strictly parallel and its angle does not have difference, the radiating that should limit in the present invention
Fin towards each other identical direction overlap on there is no marked difference.
With regard to the different standard of this angle, as long as the bearing of trend of radiating fin tabular side each other is become
Angle be less than 30 degree, just regard as radiating fin each other towards identical direction extension.On the contrary, if radiating fin each other
The bearing of trend angulation of mutual tabular side more than 30 degree, is then not to be regarded as radiating fin each other towards phase
Same direction extends.
In Fig. 1～7 described later, two panels radiating fin be formed as clipping LED element 100 each other and mutually towards identical
The form that direction extends, and arrange in parallel to each other, LED element 100 is surrounded surrounding in the rectangular shape centered on it,
And adjacent radiating fin is orthogonal each other（At right angles to intersect）Configuration.But, in the present invention, it is not limited to such
Configuration, can surround around LED element 100 on the circumference of point centered on LED element 100 or on circular arc, and sequentially change
Flatten plate-like profile angle while, radiating fin interval is configured to such as domino and topples over shape.
In addition, the piece number of the fin mutually extending towards identical direction is defined as " in two faces with substrate 102
1021st, in 1022 orthogonal arbitrary sections（In arbitrary section by the radiator of the section of the direction）For 2 with
Under " it is to prevent with respect to certain direction in three dimensions, the situation that fin exceedingly overlaps each other.As described later, even if
For a piece of fin, there is also L-shaped orThere are as shape multiple flat radiating surfaces extending to different directions
（Radiating side）Situation.It is not only flat fin, for such, there is bearing of trend or variform multiple scattered
For the fin of the shape in hot face, will for example flat shape formed L-shaped orEach line interval of shape is also regarded as single respectively
Fin, to observe the piece number in same direction（Overlapping conditions）.According to such viewpoint, arbitrary in the table back of the body with substrate
In the orthogonal arbitrary section in face of side, by make the piece number to identical towards the fin extending be less than 2 such that it is able to
Avoid radiating fin each other or radiating fin radiating side is facing with each other and situation about overlapping.That is, this is due to above-mentioned
It is defined as, regardless of whether being the radiating surface of identical fin, all by the radiating surface of radiating fin（Radiating side）Piece number regard as
The piece number of fin, and the position in two faces 1021,1022 regardless of substrate 102, all avoid excessive coincidence, thus being formed
For the regulation of described less than 2.
In this, when as the performance different from above-mentioned regulation, and the wing that will mutually extend towards identical direction
The piece number of piece is defined as when " being all less than 2 in any surface 1021,1022 of substrate 102 " for the time being it is stipulated that having gone out radiating fin
The absolute piece number of piece.Therefore, not by L-shaped orThe radiating surface of the different directions of radiating fin as shape regards fin as
Piece number, consequently, it is possible to producing excessive coincidence because the position in two faces 1021,1022 of substrate 102 is different.Therefore it is stipulated that
For described " in the arbitrary section orthogonal with two faces 1021,1022 of substrate 102（By the direction section dissipate
In the arbitrary section of hot device）For less than 2 ".
With regard to the shape of this flat radiating fin 103～106, in Fig. 1～7, exemplify global shape or flat board
Shape side is rectangle（Square）Shape but it is also possible to select to be not limited to flat shape or the 3D shape of this rectangle.For example,
As making flat radiating surface（Radiating side）To different directions（Such as more than 90 degree）The situation of multiple extensions it is also possible to
For adjacent radiating fin 103,104 each other or 105,106 be integrally formed such L-shaped, adjacent radiating fin 103,
104th, 103 each other or 105,106,105 be integrally formed suchShape.As long as can manufacture, then not only can be above-mentioned
Flat radiating surface（Radiating side）, can also have arc-shaped or curvilinear radiating surface（Radiating side）Or entirety shape
Shape.In addition, can also be in L-shaped or stepwise not on height and position towards the shape in the thickness of slab section of foreign side or thickness
With.Moreover, it is also possible to suitable select radiating surface is formed as the situation of circle, triangle, polygon, the face shape such as unsetting.
Hereinafter, the specific embodiment of the present invention of Fig. 1～7 is described, and wherein, the flat radiating to the present invention
The piece number of fin 103～106, the meaning of the regulation of configuration illustrate.That is, to making flat radiating fin 103～106
The meaning that piece number preferably adds up to 2～8 this point illustrates.In addition, also in above-mentioned radiating fin 103～106, mutually
The piece number of the fin extending towards identical direction is by the arbitrary direction orthogonal with any surface 1021,1022 of substrate 102
Section when the arbitrary section of radiator 101 in be the meaning of less than 2 and illustrate.
The first embodiment of Fig. 1：
The LED element that the flat radiating fin 103,104 of Fig. 1 is supported to LED element 100 in substrate 102
Installed surface 1021 side is total to be provided with 4, and the face 1,021 1 of flat each side of radiating fin 103,104 and substrate 102
Body and continuous setting.It is not provided with radiating fin in the back side 1022 side of the opposing party, only exist the flat back side 1022.
And, in the radiating fin 103,104 of above-mentioned LED element installed surface 1021 side setting, LED element 100 is clipped in
Between and symmetrically respectively arrange 2, and the radiating fin 103,103 of the left and right sides of figure each other and figure upper and lower sides radiating fin
Piece 104,104 is each the form mutually extending towards identical direction, and spread configuration in parallel to each other.I.e., mutually
Opposed flat radiating fin 103,103 each other and 104,104 is face side shape in LED element installed surface 1021 each other
Become in the position that LED element 100 is clipped in the middle.And, in above-mentioned radiating fin 103,104, mutually towards identical side
To extend fin piece number in the orthogonal arbitrary section in the face 1021,1022 with substrate 102（Cutd open by the section of the direction
In the arbitrary section of the radiator 101 opened）It is all 2.
And, adjacent radiating fin is orthogonal each other in radiating fin 103,104（At right angles to intersect）Ground formation,
Configuration, to surround between being clipped in LED element 100（Centered on LED element 100）Rectangular shape surrounding, and the spoke of heat
Each tabular side of the big radiating fin of rate of penetrating 103,104 is respectively facing x direction, z direction.And, the heat of substrate 102
The back side 1022 of the big LED element installed surface 1021 of radiance and the opposing party is towards y direction.
Additionally, the thickness of slab of the surrounding of substrate 102（Thickness）Each face 1023,1024,1025,1026 in direction（1023 is figure
Left side, 1024 be figure downside, 1025 be figure right side, 1026 be figure upside）Compared with described each face 1021,1022,
Smaller on area, but all directions towards x, z, become heat to the radiating surface in above-mentioned direction.In this, each scattered
The thickness of slab of hot fin 103,104（Thickness）Each face in direction（Upper surface, both ends face）Similarly although with described tabular side
Face is compared, smaller on area, but the number in face is many, upper surface, both ends face all add up to each 4 faces respectively and towards x,
Y, z all directions, become heat to the radiating surface in above-mentioned direction.
Therefore, although phase in the side being provided with LED element 100 in the planar side of radiating fin 103,104
In paired 2 face faced by mutually, radiating surface overlaps, but on the arbitrary direction of the three-dimensional of above-mentioned x, y, z, dissipates
The radiating surface of hot fin does not excessively repeat, and does not have the waste of material.Therefore, in the above-mentioned heat warp from LED element 100
By substrate 102 installed surface 1021 rearwardly 1022, each radiating fin 103, the side of 104 surrounding, thickness of slab direction face even
Resume the formation of the formation effect of continuous heat-transfer area of heat and the continuous radiating surface from above-mentioned continuous heat-transfer area continuous radiation heat
In the presence of the synergy of effect, high radiation efficiency can be obtained.
The piece number of radiating fin：
Reduce further in the piece number making the radiating fin mutually extending towards identical direction, thus with substrate 102
The orthogonal arbitrary section in face 1021,1022 in be all only provided as 2 of preferred lower limit in the case of, become and only will scheme
Appointing in the either one or both in the radiating fin 103,103 of 1 left and right sides, the radiating fin 104,104 of the upper and lower sides of figure
2 reservations in one side or two sides, and the form that other radiating fins are removed.In this case, can be by the left and right of Fig. 1
The radiating fin 103,103 of side retains each other it is also possible to retain the radiating fin 104,104 of the upper and lower sides of Fig. 1 each other, also may be used
With by radiating fin 103,104 each reservation one party.
On the other hand, certain in the case that the piece number of flat radiating fin becomes many, in the three-dimensional of x, y, z
On one direction, the radiating surface of radiating fin repeats, and the waste producing material is although space occupancy is high, but the radiation of heat effect
Rate（Radiating efficiency）Reduce.Therefore, the piece number making the radiating fin of setting is carried on the back on two faces 1021,1022 in the table of substrate 102
The piece number being respectively provided with add up to less than 8, the scope of preferably 2～8.But, in Fig. 1～7, when only making phase
Same radiating fin 103～106 directly separates, is divided into several or fine divides on the bearing of trend of radiating side respectively
From, segmentation form in the case of, regard identical radiating fin 1 as.
Problem when the total piece number of this flat radiating fin becomes many as shown in the comparative example of Figure 50, when mutual direction
Identical direction（Abreast）The piece number of the fin extending carries on the back orthogonal any in two faces 1021,1022 in the table with substrate 102

Fig. 6, the five, the 6th variation of 7 first embodiment：
Fig. 6, the LED illumination radiator 101 shown in 7 represent the sheet metal with fixing thickness of slab from such as aluminum etc.
By substrate 102（Face 1021,1022）, the integrally formed embodiment of flat radiating fin 103～105.
In this case, flat radiating fin 103～105 by the end side from substrate 102 towards respective face
Bearing of trend is z direction（The above-below direction of figure）Carry out Bending Processing, thus being integrally formed on material.5th deformation of Fig. 6
In example, fin 103,103,104,104 is bent into opposed facing shape to the upper side of figure.In 6th variation of Fig. 7,
Fin 104,104 is bent into opposed facing shape to the upper side of figure, and by lower side bending from fin 103,103 to figure
Become opposed facing shape.And, for the configuration for above-mentioned flat radiating fin 103～105, piece number, Fig. 6 and figure
1 situation is identical, and Fig. 7 is identical with the situation of Fig. 5.But, because radiating fin 103,104 passes through the end folding of substrate 102
Curved and formed, so the configuration structure being located at respectively on the end of substrate 102 is different.
The principle of radiating, effect：
During to the radiator 101 of such present invention being arranged on the space of the convection current not having air and carries out LED illumination
Radiating principle（Effect）Illustrate.When the LED element 100 making assembling on LED element installed surface 1021 lights, companion
With in this, the heat that LED element 100 sends（Heat flux）Q passes through the department of assembly of the bottom of LED element 100（Not shown）And
Conduct to the LED element installed surface 1021 of substrate 102.And then, it is transmitted to heat Q on LED element installed surface 1021 not only
To the radiating fin 103,104 of installed surface 1021 side, but also rearwardly 1022, the radiating fin 105 of this back side 1022 side,
106 is with roughly equal high level and continuous and rapid with above-mentioned each radiating surface（Not delayed）Ground transmission（Conduction）.Therefore,
From the heat-delivery surface of above-mentioned fin convection current and especially by the radiating that carries out of radiation equally with certain level more than
Carry out such that it is able to improve radiating efficiency.
Here, as the regulation of the present invention, in radiating fin 103～106, mutually towards the wing of identical direction extension
The piece number of piece is all less than 2 in the orthogonal arbitrary section in the face 1021,1022 with substrate 102, in a same direction
Will not excessively overlap.Therefore, the heat Q of above-mentioned transmission is respectively facing the three-dimensional of x, y, z, and the installation from substrate 102
The promptly peripherad closing respectively such as face 1021, the back side 1022, surface of described each radiating surface of radiating fin 103～106
Space（Heat-dissipating space）Effectively eradiation.Therefore, arbitrary direction from the heat that LED element 100 sends to three-dimensional x, y, z all
Radiated with the high radiation efficiency that heat dissipation capacity is necessarily above.Although this is because, radiator 101 radiating fin of the present invention
The piece number of piece 103～106 is few, but the efficiency radiating at it is by the closing in the few ligthing paraphernalia of the cross-ventilation radiating domination
Heat-dissipating space in, all big with respect to each projected area of all directions in x, y, z direction.The radiator 101 of the present invention have as
Under such excellent characteristic：Although the few simple structure of the piece number of radiating fin 103～106, often radiate unit plane
Long-pending radiating efficiency is good.
Here, configuring in the narrow space of vehicle-mounted illuminating housing or in closing space when needing and passing through to radiate
When being radiated, the x, y, z direction of principal axis that each in figure represents（Three-dimensional）On the size of projected area determine its efficiency, this throwing
Shadow area is bigger, and the radiation efficiency of heat is got over and improved.
For this point, the radiator 4 of the conventional example of Figure 47 or comparative example is baseplate part 2 due to the projected area in y direction
The plane of upside of plane and fin part 3 total, therefore fin part 3 does not have overlap each other, does not therefore have the waste of material,
And projected area is big.But, the projected area in z direction is the side of baseplate part 2 and adding up to of the side of fin part 3, becomes comb
Dentation and space is many, therefore becomes and is unsatisfactory for the length of baseplate part 2 and is multiplied by the 50% of the gross area that the height of fin part 3 obtains
Little area.In addition, the projected area in x direction is the front of baseplate part 2 and adding up to of the front of fin part 3, although fin part 3
There are such as 4, but they repeat, thus being and 1 identical projected area, the waste of material is many, the heat of every area of dissipation
The radiation efficiency of amount is low.I.e., in the x direction, multiple fins repeat and occupy space although its space occupancy is high, but projection
Area is little, and the radiation efficiency of heat is low.And, the piece number of this x direction fin is superfluous, the waste of material because of this superfluous fin
Also big, also there is a problem of that weight becomes weight.
In other words, the x, y, z direction of principal axis of the radiator 4 of the conventional example of Figure 47 or comparative example（Three-dimensional）A direction
Heat the certain step-down of radiation efficiency.As a result, the radiation efficiency of the heat in certain direction of three-dimensional cannot be improved,
The radiation efficiency step-down of therefore total heat.In addition, on above-mentioned x direction etc., the piece number of fin is superfluous and the waste of material
Also big.That is, in above-mentioned prior art, something in common is it is impossible to be formed on the arbitrary direction of the three-dimensional of radiator, material
Material does not all waste, although and space occupancy is low, the high radiator of the radiation efficiency of heat.
In addition, with regard to this point, Japanese Unexamined Patent Publication 2010-146817 publication similarly, in multiple arrangementsThe handle of shape
On the direction that the radiating part of Wood-scoop part repeats, space occupancy is high, but the radiation efficiency of heat is low, from three three-dimensional directions
From the point of view of the radiation efficiency of total heat, the waste of the especially material in x direction is many.In addition, the peristome in described slit-shaped
For ensuring that the big restriction of the area of the size of radiator itself or described radiating part side on width, thus necessarily being formed
For narrow width, when therefore in the space being applied to closing, the raising of the radiating efficiency being radiated by the convection current of air is in reality
Also cannot play as expecting on border.
Radiator of the present invention heat-dissipating space around is closed, volume is little and convection current that is almost not having air is such uses
（Setting）Under state, almost cannot expect the use radiated by the convection current of air（Setting）The most suitable under environment.
Under such use environment, in order to radiate, need centered on being radiated by radiation, by increasing dissipating of fin etc.
Hot-face surface amass and using the convection current of air as in the above-mentioned existing heat spreader structures of main heat dispersion, by this radiation
The radiating carrying out is insufficient, integrally cannot realize effectively radiating.In contrast, in radiator of the present invention, by from described
The radiating that the radiation of the heats of radiating surface such as radiating side is carried out is main body, can be referred to as to be best suited for almost cannot expecting to lead to
Cross the use of the radiating that the convection current of air is carried out（Setting）The radiator of environment.
And, each radiating surface comprising LED element installed surface 1021 and radiating fin due to be between them not via
The integrative-structure on composition surface, thus without the thermal contact resistance producing when producing both joints above-mentioned making respectively.Therefore,
Conduction of heat between LED element installed surface 1021 and each radiating surface is easy, as a result, the overall heat dispersion of radiator is notable
Improve.And, the structure being each direction towards three-dimensional x, y, z for the radiating fin due to the structure of radiator 101, so
Rigidity is high.Therefore, even purposes vibrated is not it is also possible to use special stiffener etc. in vehicle-mounted illumination etc.
In the case of keep its shape, be capable of freedom from repairs and high life.
The identical item of the first embodiment including each variation：
The installed surface 1021 of substrate 102 described above, the back side 1022, radiating fin 103～106 each radiating surface
On, can be according to the purposes of radiator 101 or installation position, by excising cutting of above-mentioned face on one of above-mentioned each face
Except the forming of the three-dimensional of processing or the concavo-convex or step of setting etc., come space, slit or the part of set parts installation
Shape etc..And, side needing it is also possible to omit or change shape the part in each face according to part installation etc. of radiating.
The radiator 101 of the present invention does not make the shape of radiator, structure, the especially shape of radiating fin, complex structure
Change, do not increase the number of radiating fin, just can in the case of the number simplifying the structure and reducing radiating fin on the contrary making
Realize excellent radiating effect.As a result, various raw materials, manufacture method or manufacturing process can be selected, using the teaching of the invention it is possible to provide honest and clean
Valency and the easy radiator making.Raw material, material for example can select aluminum（Fine aluminium）Or aluminium alloy, copper（Fine copper）Or copper alloy,

（Aluminum）
Wherein, it is intensity, rigidity, lightweight, corrosion resistance, heat transmitting, heat as the necessary characteristic having both radiator 101
The raw material of thermal diffusivity, processability etc., preferably aluminum（Fine aluminium）Or aluminium alloy.Aluminum（Fine aluminium）Or required by the preferred radiator of aluminium alloy
Thermal conduction characteristic and 1000 fine aluminiums being specified in the king-sized specification in AA or JIS of heat dissipation characteristics.
When the lightweight, necessary intensity, rigidity and the drawing process that consider radiator（Formability）When, substrate 102, dissipate
The thickness of slab of hot fin 103～106（Thickness）Or raw material is thickness of slab during sheet metal（Thickness）Preferably from 0.4mm～4mm's
In the range of select.When this thickness of slab is excessively thin it is impossible to guarantee necessary intensity, rigidity or the processability of radiator（Formability）.Separately
On the one hand, when this thickness of slab is excessively thick, the lightweight of radiator can be sacrificed.
（The emissivity of radiating surface）
The radiator of the present invention in order to obtain high thermal diffusivity, the emissivity ε of preferably described sheet metal be 0.6 with
On.Therefore, before drawing process, the whole surface of feed metal thin plate can be implemented with the high black of rate of heat dissipation, Lycoperdon polymorphum Vitt, white
Deng coating precoating process（Application envelope）.Or, the high above-mentioned coating of radiance can be implemented after drawing process
Coating processing afterwards（Application envelope）.Thereby, it is possible to increase as radiator by radiating the transmission heat being transmitted.This is pre-
If coating processing is implemented to feed metal thin plate before drawing process in advance, also act as the work of the lubricant in drawing process
With.
This radiance ε is the thermal-radiating theoretical value with respect to actual object（Black matrix as preferable heat radiator
Heat radiation）Ratio, actual mensure can also may be used using the method described in Japanese Unexamined Patent Publication 2002-234460 publication
Measured so that device is measured by marketed portable type radiance.
（Assembling to Vehicular lamp）

Figure 15 represents the LED illumination radiator 301 of the 3rd embodiment.This LED illumination radiator 301 is by aluminium sheet
302 form it is characterised in that having horizontal plane 311,312 and vertical front side portion 321,322 is alternately continuously stepped,
LED element 300 is equipped with the surface in horizontal plane and/or vertical front side portion.Wherein, horizontal plane 312 constitutes this
The assembling face of invention, vertical front side portion 321,322 constitutes first fin part of the present invention, vertical side face described later 331～
Second fin part of the 338 composition present invention.
Specifically, as shown in figure 15, the radiator 301 of the 3rd embodiment is by the aluminum with fixing wall thickness（Including
Its alloy）Plate 302 is formed, and entirety has stair-stepping shape.That is, in the case of in figure, it is the stepped of 2 ranks, by aluminum
Plate 302 is formed, and the basic configuration of entirety have stepped.That is, in the case of in figure, stepped in 2 ranks, and from ladder
Top, with its horizontal plane 311, vertical front side portion 321, horizontal plane 312, the sequentially forming of vertical front side portion 322
It is that mutually rectangular horizontal plane and vertical front side portion be alternately continuous and the shape that constitutes（Structure）.
Above-mentioned horizontal plane 311,312 and vertical front side portion 321,322 are all rectangle, this rectangle with formation
The width identical length of stair-stepping aluminium sheet 302 is long side, and carries out the width of 4 deciles as minor face with the length to aluminium sheet.
300 is the LED element of the central part assembling in horizontal plane 312.
And, in horizontal plane and vertical front side portion, in the both sides of horizontal plane 312 and vertical front side portion 321
End is also equipped with vertical side face 331,332 that is rectangular with them, vertically configuring.Vertical side face 331,332 be with
The width in described horizontal plane 311,312 and vertical front side portion 321,322 is the square on one side.
Then, it is arranged on the space of the convection current not having air and carries out to by having such stair-stepping radiator 301
The principle of radiating during LED illumination, effect are described.When the LED element 300 making assembling in horizontal plane 312 lights
When, it is accompanied by this, the heat that LED element 300 sends is conducted to horizontal plane 312 by the department of assembly of LED element 300.Tightly
Then, the heat being transmitted to horizontal plane 312 is to vertical front side portion 321, vertical front side portion 322, vertical side face 331,332
Conduction.So, it is transmitted to the heat of the horizontal plane 312 vertical front side portion to more than 2 faces continuous with horizontal plane 312
Or vertical side face conduction.And, it is transmitted to the heat Q of horizontal plane 312 and also carry on the back whole face from the table of this horizontal plane 312
To its right angle orientation（The above-below direction of Figure 15）Surrounding closing space（Heat-dissipating space）S radiates, and is transmitted to vertical front side portion
321 heat Q from this vertical front side portion 321 table the back of the body whole towards its right angle orientation（The left and right directions of Figure 15）This space S spoke
Penetrate, be delivered to the heat Q of vertical side face 331,332 from the whole face of vertical side face 331,332 respectively to their right angle side
To（The right side of Figure 16 and left direction）This space S radiation.It should be noted that from vertical side face 331 towards LED element
300 side（The left surface of Figure 15）, 332 side towards LED element 300（The right surface of Figure 15）Also respectively to figure
