In the aforementioned embodiment, each light source all has a pair of substantially parallel lead-in wire, and they extend along the first type surface of bonding conductor structure (perhaps patterned conductor).But, may there be such a case, wish that promptly light source is fixed into the first type surface that makes lead-in wire be substantially perpendicular to the bonding conductor structure to be extended, perhaps described light source is made up of a kind of so-called chip type LED that does not have lead-in wire.The following examples are applicable to these situations.
Figure 16 is a fragmentary, perspective view, shows another according to light source assembly preferred embodiment of the present invention.As shown in the figure, light source assembly 101 has used a large amount of light-emitting diodes (LED) 102 as light source, and each LED102 has the lead-in wire 103 that pair of parallel is extended by a bullet type LED (perhaps lamp type LED) composition.LED102 and is tabular bonding conductor structure 104 basically by one and is electrically connected perpendicular to lead-in wire 103 direction setting along one, and described bonding conductor structure 104 is extended along the orientation of LED.In shown embodiment, LED102 is in connection in series-parallel state (the series connection part that is a plurality of LED is together in parallel), but as described below such, can be in series connection or state in parallel according to the structure of bonding conductor structure 104.
Each terminal connecting portion 109 in the bonding conductor structure 104 is made into to have the hole 116 of a cross shape, thereby makes and can to realize in the cross bore 116 that by LED102 is inserted into mechanical/electrical is connected between LED102 and the bonding conductor structure 104.It is protruding to extending in four that the cross shape in hole 116 provides, and they are pushed hand-hole 116 and deflection takes place along with lead-in wire 103, firmly fix thus and go between 103.As in Figure 17 a clear illustrate, wherein Figure 17 a is a cutaway view along Figure 16 center line XVII-XVII, after each root lead-in wire 103 is inserted in the hole 116 that is associated, the extension 117 that is arranged on the both sides in hole 116 and transversely extends, bending will go between 103 clampings or pressure holding between them.This helps to prevent from reliably to go between and 103 accidental running away is taken place from hole 116.After clamping, 103 cut going between, so that have suitable length by extension 117.Lead-in wire 103 can the predetermined length of cropped in advance one-tenth.As shown in the figure, lead-in wire 103 can be inserted in be associated groove or the hole 124 that is formed on the mounting panel (carriage) 123, and light source assembly 101 is affixed on the carriage 123.
Except will go between 103 be inserted in the hole 116 and utilize extension 117 will go between 103 clamp, go between 103 with terminal connecting portion 109 between be connected and can realize by point type welding, ultrasonic bonding, laser welding or the like.But, it is pointed out that aforementioned clamping operation can have some advantages, such as, can utilize the gradual pressure machine to carry out continuous processed, avoid using scolder and avoid taking into account heat and will produce harmful effect LED102.Also can both adopting to go between 103 is inserted in the hole 116, adopts laser welding again.In this case, hole 116 has interior to projection shown in the figure, can help more stably to realize laser welding,, can increase contact area thus because interiorly can be inserted into along with lead-in wire 103 in the hole 116 in and bend and be pressed against and go between on 103 to projection.Can be on the interconnection vias 110 adjacent part place otch that is shaped with hole 116, so that form a tongue piece, and crooked this tongue piece, make this tongue piece clamp from three directions extension 117 and go between 103 with described that.
Also have, as shown in the cutaway view among Figure 17 b, so-called " receptacle pin " 125 can be inserted in the hole 116, is used for coupling together with lead-in wire 103.A receptacle pin comprises a conductor, and this conductor has a pin portion (projection or public type part) and a receptacle portion (indent or parent form part) that is formed at the pin portion back side, and can be used as one such as the PD string that is provided by MAc-Eight.By pin portion being pushed in advance in the perforation 116, being electrically connected between LED and the bonding conductor structure 104 can 13 be inserted into realization easily in the receptacle portion of receptacle pin by going between.
According to the present invention, foregoing bonding conductor structure 104 can obtain by some part of excising as required on the patterned conductor in the course of processing secondarily, wherein said patterned conductor is by carrying out pressure processing (die-cut) and made in advance having a circuit diagram to a kind of conductive sheet metal in the preliminary working process, and this circuit diagram can be common to series, parallel or connection in series-parallel.By this way, by changing the part to be excised in the described patterned conductor, light source 102 series, parallel or connection in series-parallel can be got up.
Figure 18 is a partial plan view, shows a patterned conductor preferred embodiment 120 before inferior processed.In this accompanying drawing, utilize identical Reference numeral to be referred to corresponding parts in the structure of bonding conductor shown in the front 104.As illustrated in the accompanying drawings, 120 one-tenth strips of patterned conductor have self-supporting feature (perhaps parts wherein are whole), and wherein interconnection vias 110 extends along the longitudinal, come the light source part 105 that is connected is connected.First main line 111 and second main line 112 are set on the either side of patterned conductor 120, so that interconnection vias 110 and the light source part 105 that is connected is placed between them.The terminal connecting portion 109 that each light source is connected on the part 105 all is connected on first main line 111 and second main line 112 via the branch road 113,114 that is associated.Interconnection vias 110 comprises a large amount of connecting path 121, each connecting path 121 all links pair of terminal connecting portion 109, and described terminal connecting portion 109 is in order to cooperate lead-in wire 103 on the adjacent different LED 102 (promptly be included in adjacent light source be connected terminal connecting portion 109 in the part 105).Can be set at (referring to Figure 16) on the connecting path 121 by the molded connector that forms 115 of folder thing.In the process of shaping connector 115, the part that aligns with the connecting path 121 that is associated on each connector 115 is made into to have a hole 119, manifests connecting path 121 (that part of connecting path 121 that is revealed by hole 119 is known as bridge part 121A (referring to Figure 19 to 21)).By this way, after forming connector 115, the drift (not shown) on the forcing press can be inserted in the perforation 119, excises bridge part 121A, so that will be separated by the terminal connecting portion 109 that connecting path 121 couples together thus.
As previously mentioned, patterned conductor 120 is converted into bonding conductor structure 104, this bonding conductor structure 104 is come to excise some part as required according to purposes and is had one and have the predetermined circuit that connects pattern by carrying out time processed, and described processing preferably can main line 111,112 and interconnection vias 110 by utilize the molded connector that forms 15 of folder thing link together after introducing.By so, can prevent that some part of final bonding conductor structure 104 from separating.Produce connector 115 and patterned conductor 120 is carried out time processing carry out in a tinuous production if be shaped by the folder thing, this will be efficiently.Therefore, in order to allow to carry/align in production line, second main line 112 is made into such as having location hole 118, and the alignment pin (not shown) that is used on a gradual pressure machine cooperates.
Foregoing patterned conductor 120 preferably can be by obtaining by carrying out pressure processing (more particularly, die-cut) such as aluminium or the so metal conductive sheet metal of copper a kind of.Aluminium is not used in the printed circuit board (PCB) because the affinity of itself and scolder is relatively poor, but have lower proportion (be approximately copper proportion 1/3rd), and the light-end products that is thus suitable for being shaped.Also have, just have the viewpoint of high thermal conductivity (being the several times of the thermal conductivity of copper) and high electrical conductivity, aluminium also is preferred.Also have, copper on the printed circuit board (PCB) is thin to be approximately 35 microns although be positioned at, and the thickness of patterned conductor can be 100 to 300 microns, allows bigger electric current to flow through.With regard to the viewpoint of heat radiation, this also is favourable.Patterned conductor 120 can optionally form by conductive sheet metal is carried out photoetching treatment, perhaps by cut by means of steel wire, laser or discharge mechanical treatment cut conductive sheet metal and form.Molded such diecasting is handled and also can be used such as magnesium.Patterned conductor 120 has flexibility, and can freely bend or complications, and can twine rolling thus or be folded into a kind of accordion form, thereby makes it can be easy to storage, carry or packing.
Figure 19 to 21 shows some kinds processing modes of patterned conductor 120, is used for LED102 connection in series-parallel respectively, connects and be together in parallel.In these accompanying drawings, utilize hatching to show part to be excised.Also have, in order to help to understand position to be excised, connector 115 has hole shown in broken lines 119.
Example shown in Figure 19 provides a kind of like this bonding conductor structure, and it can be together in parallel a plurality of series connection parts of being made up of three LED102 (concatenation function piece) between main line 111 and 112.More particularly, the bridge part 121A on the connecting path 121 between adjacent string connection functional block is cut, and is used for keeping intact at the connecting path 121 of each concatenation function piece interior bonds terminal connecting portion 109.Be connected in branch road 113 on first main line 111 and one except one place, another one end is connected in branch road 114 on second main line 112 at place, end, the branch road 113,114 that is arranged in each concatenation function piece is cut.Should be appreciated that the number that is included in the LED102 in each concatenation function piece can change by changing removed branch road 113,114 and bridge part 121A, and be not limited to three thus.In example shown in Figure 19, be used for the adjacent LED 102 that is included in same concatenation function piece is connected the bridge part 121A of (perhaps being used for connecting) and keep not cutting being included in the be connected terminal connecting portion of part 105 of adjacent light source.But, dotted line is shown like that in the perspective view just as shown in Figure 16, when a resistor 122 when being connected on the interconnection vias 110 by point type welding or laser welding, for resistor 122 is inserted between the adjacent LED102, the bridge part 121A that is about to be placed between the pair of terminal on the resistor 122 can be cut.Similarly, still as shown by dashed lines, when resistor 122 was connected between the interconnection vias 110 and second main line 112, the branch road 114 that is positioned at the corresponding position was with cut.This is applied to a resistor equally and is connected under the situation between the interconnection vias 110 and first main line 111.
In example shown in Figure 20, bridge part 121A is by complete resection, and branch road 113,114 is cut, so that make be connected in that each LED102 goes up (perhaps in same light source is connected part 105) that to being connected on the main line 111 one of in the terminal connecting portion, another one is connected on the main line 112 simultaneously.This just provides one to be used for being installed on the light source bonding conductor structure that LED102 on the part 105 is together in parallel that is connected between main line 111 and 112.
In example shown in Figure 21, all branch roads 113,114 are cut, and simultaneously bridge part 121A is all stayed without cutting, thereby make between main line 111 and 112 one of formation by connecting that LED102 forms.We can say that each connecting path 121 has formed one with described that to the terminal connecting portion 109 that coupled together by connecting path 121 and has been used for connecting piece that adjacent LED 102 is connected.In comprising the light source assembly 101 that is formed for bonding conductor structure that LED102 is connected thus, the lead-in wire 103 such as on the LED102 that light source voltage can be applied to the place, end that is positioned at the LED series connection need not to use main line 111,112.But, also can keep suitable branch road 113,114, so that LED is connected in series on the main line 111,112, the LED series connection has a voltage via the main line 111,112 that is connected on the power supply thus.One of can only use in the main line 111,112 and to be connected on the power supply.
As previously mentioned, according to a preferred embodiment of the invention, can utilize generic patterned conductor by changing cut branch road 113,114 and bridge part 121A, can be shaped bonding conductor structure 104 (and the light source assembly 101 that has used them) with multiple connection pattern.Described patterned conductor is carried out the inferior bonding conductor structure 104 that is shaped of processing preferably to be realized by pressure processing, wherein treat excision branch road 113,114 and bridge part 121A choose be shaped have the different bonding conductor structures 104 that connect patterns can computer control, and therefore need not to change the mould in the forcing press, and this will be avoided helping thus to enhance productivity and reduce manufacturing cost owing to die change is operated time loss or the misoperation that causes.Also have,, can avoid using the scolder relevant usually with printed circuit board (PCB) owing in the process of shaping light source assembly 101, need not to use printed circuit board (PCB).This has not only reduced the harmful effect to environment, and has avoided the harmful effect of the heat that produces when going up the use scolder at light source (LED).Described light source assembly has a kind of very simple structure, this structure is made of light source (LED) and bonding conductor structure, and be easy to dismounting thus, simultaneously owing to do not use printed circuit board (PCB), so can advance recycling efficiently, wherein said printed circuit board (PCB) generally is difficult to carry out recycling.

Figure 36 is a fragmentary, perspective view that is similar to Figure 16, and shows another embodiment of connector, and Figure 37 is its upward view.In these accompanying drawings, utilize identical Reference numeral to be referred to similar parts among Figure 16, and omitted detailed description them.At this light source assembly 101 " in; heat insulating lamella that laterally extends and extend along the longitudinal 184 ' be used as connector; be used to connect main line 111,112 and interconnection vias 110, wherein said heat insulating lamella 184 ' have predetermined length and making by vinyl chloride along bonding conductor structure 104 (perhaps patterned conductor 120).Heat insulating lamella 184 ' can extend along the whole length of patterned conductor 120.This heat insulating lamella 184 ' also patterned conductor 120 is being carried out utilize suitable measure to be connected on the patterned conductor 120, before time processed such as binding agent.Also have, can heat insulating lamella 184 ' on perforation is shaped in reservations office (such as the part that aligns with location hole 118, perhaps being used for the part of the lead-in wire 103 on the ccontaining LED102).As in upward view shown in Figure 37 clear illustrate, in the present invention, opening 185 is configured to manifest terminal connecting portion 109 on the bonding conductor structure 104 (be light source be connected part 105), allows thus to be used to carry out the laser beam irradiation of laser welding to the part that reveals from the bottom side.Be similar to the embodiment that has used a large amount of heat insulating lamellas 184 shown in Figure 35, the embodiment shown in Figure 36 also can obtain a kind of and utilize the molded littler or thinner light source assembly of light source assembly that forms of folder thing.Also have, compare with a large amount of heat insulating lamellas 184, the heat insulating lamella 184 shown in Figure 36 ' can be by easier and utilize shorter time to be affixed on the patterned conductor 120.In Figure 36, the whole width of heat insulating lamella 184 ' extend through bonding conductor structure 104.But, heat insulating lamella 184 ' only must connect to main line 111,112 and interconnection vias 110, and thus need not the essential whole width of extend through.For example, it can have such width, promptly can not close location hole 118.
Thereby make main line 111,112 first type surfaces perpendicular to interconnection vias 110 by branch road 113,114 being carried out bending, and as shown in Figure 38 main line 111,112 is inserted in the groove 181,182 that is associated subsequently, uses as shown in Figure 36 that heat insulating lamella 184 ' " can be affixed to one easily is made into to have on the mounting panel (carriage) 180 of groove 181,182 as the light source assembly 101 of connector.Mounting panel 180 can be made into to have a groove or perforation, is used to be contained in light source assembly 101 " bottom side on the parts that come out of projection, such as the lead-in wire on the LED102 103.Mounting panel 180 can form by molded, so that light source assembly becomes as a whole.Also have, a large amount of light source assemblies 101 can transversely be set ", form a two-dimension light source.In this case, preferably the vertical and horizontal spacing of LED102 is adjusted to equal.In light source assembly 101 illustrated in fig. 16, main line 111,112 on the bonding conductor structure 104 and interconnection vias 110 link together by utilizing the molded connector that forms 115 of folder thing.But after LED102 had been affixed on the bonding conductor structure 104, main line 111,112 and interconnection vias 110 were got up by LED102 and branch road 113,114 unitary fixed, and thus, can economize except that connector 115.Still in this case, light source assembly 101 can be connected on the mounting panel in a kind of to similar shown in Figure 38 mode.This also is applicable to the light source assembly shown in Figure 22.
Figure 39 is a perspective view, shows a kind of light source assembly 101 that used " light-emitting device embodiment 190, such as shown in Figure 36, light source assembly 101 " has used heat insulating lamella 184 ' as connector.Figure 40 is a transverse sectional view along line XL-XL, and Figure 41 is its schematic plan.In these accompanying drawings, utilize identical Reference numeral to be referred to similar parts among Figure 36, and omitted detailed description them.As in Figure 41 clear illustrate like that, in the present embodiment, be included in light source assembly 101 " in N LED connect among the L1 to LN that each includes four LED102 and a chip type resistor 156 (referring to Figure 31) that is together in series with LED102.To chip type resistor 156 be connected operation can by excision interconnection vias 110 (perhaps connecting path 121) go up the part between the adjacent LED 102, with chip type resistor 156 across the cut-out placement and the terminal on the resistor 156 is laser-welded on the connecting path 121 realizes subsequently.Certainly, being included in the be connected in series number of the LED102 in the partial L 1 to LN of each LED can change arbitrarily.
Light-emitting device 190 illustrated in the accompanying drawings comprises a printing opacity pipe fitting 191, and this printing opacity pipe fitting 191 is cylindric, and as a housing, holds light source assembly 101 therein ".When use has enough undersized LED102 pipe fitting 191 can have such as 0.5 to 2 centimetre than minor diameter.Printing opacity pipe fitting 191 can be made by a kind of plastics, and still with regard to the viewpoint of high efficiency and heat radiation, preferably pipe fitting 191 is made up of a glass tube, and it has favourable thermal conductivity.
Each end of pipe fitting 191 all has an end cap 192, is fixing pair of conductive pin 193.On each end of pipe fitting 191, described that to being connected light source assembly 101 one of in the conductive pin 193 " in first main line 111 on, and another one is connected on second main line 112.By this way, be connected on the power supply, can give light source assembly 101 with the supply voltage feed via main line 111,112 by the pair of conductive pin 193 that will be arranged on 191 1 ends of pipe fitting " in LED.
Therefore, in the present embodiment, light source assembly 101 " in main line 111,112 can be used as distribution (perhaps circuit), be used for LED102 is connected to power supply.Compare with the situation of the extra distribution of needs, this can obviously improve the efficient of packaging technology.Also have, described light-emitting device can be connected on the another one light-emitting device 190 via the conductive pin 193 that is associated, and so repeats, and can connect any a plurality of light-emitting device 190.In this case, for the ease of connecting, can make that being positioned at a conductive pin 193 on the end is public type, the conductive pin 193 that is positioned at simultaneously on the other end is parent form.The cable joint that also can use a kind of specialized designs to become to be used to carry out this connection.It must be noted that if wish independent use equipment 190, first main line 111 in the light source assembly assembly 151 and second main line 112 can only be connected on the independent pin 193 that is positioned on 191 1 ends of pipe fitting so.
In the shown light-emitting device 190 of Figure 39 to 41, in running order resistor 122 or LED102 can produce heat.Also have because the end of pipe fitting 191 is closed by end cap 192, so if pipe fitting 191 have such as 0.5 to 2 centimetre such than minor diameter, will cause less thermal convection so.Therefore, if used a kind of printed circuit board (PCB) that has the circuit-forming copper film of about 35 micron thickness and have relatively poor thermal conductivity (perhaps low heat-transfer rate) thus, so by will converge in such as resistor 122 and the such heat that element produced of LED102 these elements around, cause these component ambient atmospheric temperatures to raise fast.This can cause described element is caused damage or reduces their performance.But, used light source assembly 101 at the light-emitting device shown in Figure 39 to 41 190 "; " comprising can be by carrying out the bonding conductor structure 104 (Figure 38) that pressure processing (preliminary working and time processing) forms to a kind of conductive sheet metal for light source assembly 101, and the general thickness of described sheet material can be 0.1 to 0.3 millimeter, obvious thickness greater than the copper film on the printed circuit board (PCB).Therefore, compare with printed circuit board (PCB), heat conductivility can improve greatly, and can be scattered and disappeared fast by the heat that described element produced.This excessive temperature that can prevent described component ambient raises, and realizes equably that basically pipe fitting 191 temperature inside distribute.
In addition, utilize such as welding or the such measure of screw, first main line 111 and second main line 112 are fixed with the crooked heat transfer plate 194 of great number of elastic, and wherein heat transfer plate 194 is preferably by making such as the such metal of aluminium, and as heat transfer piece.Heat transfer plate 194 also as strutting piece, is used for light source assembly 101 " being supported on pipe fitting 191.As shown in the cutaway view, heat transfer plate 194 all has a cross section shape that extends along the inner surface of pipe fitting 191, and contacts with pipe fitting 191 pressure.This can allow heat to be passed to glass pipe fitting 191 via heat transfer plate 194 from first main line 111 and second main line 112, and is scattered and disappeared to outside from pipe fitting 191 subsequently, is suppressed at pipe fitting 191 internal temperatures thus and raises.In other words, use heat transfer plate 194 to allow pipe fitting 191 as a fin.Come out to use outside the situation of glass pipe fitting 191, " when being accommodated in the housing of being made by such inhibition material; be that described material has favourable thermal conductivity and insulation property; such as pottery, aforementioned heat transfer plate can be used for heat transferred is scattered and disappeared to outside to housing and via housing similarly when light source assembly 101.Although it is pointed out that employed heat transfer plate 194 is all less relatively in shown embodiment, also can use the heat transfer plate 194 that has equal length basically with pipe fitting 191.Also have, the shape of described housing can be not limited to tubulose, and the shape of heat transfer plate 194 also can change according to the shape of housing.If light source assembly 101 " all or part upper surface and/or lower surface be black, this also will be preferred, because this can allow heat to carry out radiation as infrared ray.Color can be handled by the plating of application black nickel, the plating of black chromium or chromate and realize, perhaps uses black anodizing aluminium to realize as material.
