Figure 21 is mounted in the illustrated view of the one embodiment of the present of invention in the glass cabinet.

Fig. 1 there is shown the luminescent system 1 that the supporting mass 3 by the substrate form shown in LED light-emitting device 2 and the part constitutes as sectional view in side-looking.

LED light-emitting device 2 has the LED 4 that emits white light as light source, and it is installed on the housing 5 and the device 6 that is reflected in the side for the beam guiding surrounds.For to LED 4 and 7 power supplies of the exciting circuit that is used for LED 4 in housing 5, from housing 5, draw the contact leg 8 of mechanical flexibility, they have the foot 9 of permanent magnetism respectively.Foot 9 be used for thus LED light-emitting device 2 electrically contact with and releasable fixing.The unit that comprises housing 5 (having exciting bank 7), LED 4 and reflector 6 also can be called led module 2a.

Smooth supporting mass 3 has the

electrical contacts

11,12 that is embedded in the supporting mass material 10, and their surface 13 exposes and thus serve as the electric interface and the placement surface of foot 9.Shown

contact site

11,12 has different electromotive forces, makes to be used for driving LED 4 by them by light-emitting device 2 intercepting electrical power.

Contact site 13 is configured to placement surface 13 in its function aspects, makes magnetic foot 9 can plane earth attached to it.For this reason, contact site 11,12 preferably has permanent-magnet materials, and this material has magnetic polarity on contact-making surface 13, and this magnetic polarity is opposite with the magnetic polarity of related foot 9.Contact site 11,12 has opposite magnetic polarities, is used for LED light-emitting device 2 aligned with each other about its contact-making surface 13.So when the direct current supply of contact site 11,12, the positive potential of left side contact site 11 links to each other with positive magnetic polarity on its surface 13, and the less electromotive force of the right contact site 12 (for example) links to each other with negative magnetic polarity on its surface 13.Correspondingly, be connected to foot 9 on the positive electromotive force and have negative magnetic polarity on its contact-making surface, have positive magnetic polarity on its contact-making surface and will be connected to foot 9 on the lower electromotive force.In this way, especially in the DC driven of LED light-emitting device 6, can guarantee correct electric polarity, because under the situation of the misorientation of LED light-emitting device 2, its foot 9 and contact site 11,12 repel mutually, and only attract each other under the situation of correct orientation.Magnetic polarity identifies with symbol "+" or "-".Alternatively, the contact site of supporting mass 3 or foot 9 have ferromagnetic material, especially iron material such as steel.

In this way, LED light-emitting device 2 can simple especially and contact with saving the position.

Reflector 6 can hide by transparent lid 14 and be used to protect light emitting diode 4.

During especially can driving in the interchange of

contact site

11,12, exciting circuit 7 is designed to the driver of light emitting diode 4.In addition, exciting circuit 7 can have other different functions, and dimming function for example on purpose reduces the luminous intensity of LED 4 when activating this function.Another possible function is, for example under the situation of the led color that uses color LED different, that can individually encourage to constitute bunch, uses the light-emitting device of color changeable to change the glow color of light-emitting device.

Exciting circuit 7 has receiving system 15 in order to activate different functions, and this receiving system has the radio control signal that wireless aerial is used to receive wireless transmission.Receiving system 15 is coupled with communication mode with exciting circuit 7, makes that exciting circuit 7 can changeover control signal.

In addition, optionally addressing of exciting bank 7 also is that the instruction of its identification code that will have coupling (Identcode) is changed, and the instruction of the identification code that do not have coupling is not changed.In this way, can encourage the LED light-emitting device 2 that has same identification code or the group of LED light-emitting device 2 targetedly.So, especially can optionally encourage the group of the light emitting diode or the light-emitting device of same color, so that for example change the colour vision of system, for example by connecting and/or turn-off the light-emitting device of determining color.

Fig. 2 has illustrated the supporting mass 3 that has six

contact sites

11,12 comparing with the view of Fig. 1 in the wideer part.Six

contact sites

11,12 are connected on the direct voltage source 16, make them form first group contact site 11, and these contact sites link to each other with the positive pole of direct voltage source 16, and the contact site 12 that forms second group, and they link to each other with the negative pole of direct voltage source 16.Each LED light-emitting device 2 with magnetic means with its terminal attached to from the contact site of first group and second group a pair of.So LED light-emitting device 2 is connected in parallel on electricity.

Can connect (unshowned) exciting circuit here by supporting mass 3 and be used to encourage the light-emitting device 2 that links to each other with supporting mass 3.So, can provide dimming function alternatively or additionally by this exciting circuit, this exciting circuit is to less ground of the subclass feed of all contact sites or selected contact site.Be that light modulation just can realize by exciting circuit only, and cost is cheap especially thus in that the advantage that dimming function has is set on the supporting mass rather than on light-emitting device.On trend,, realize function as much as possible by the exciting circuit of supporting mass 3, rather than realize by the exciting circuit 7 of light-emitting device for reducing expense advantageously.Exciting circuit 7 can optionally be worked, and its mode is the control signal of only changing at the light-emitting device design of determining.So one of shown light-emitting device 2 can be at the data-signal that is provided with definite identification code and with the downward light modulation of luminous intensity, and another light-emitting device 2 does not react for the light modulation instruction.Control signal for example can be transmitted by the modulation of carrier signal.So exciting bank preferably has corresponding data read function, for example decoder.

Alternatively,

contact site

11,12 also can differently connect.Also can use the power supply of another type, for example AC power.Usually, supporting mass can be equipped with suitable power supply unit, for example has transformer and is used for changing line voltage into supply voltage, in case of necessity by using rectifier.

Fig. 3 shows the LED light-emitting device 2 among Fig. 1, yet this LED light-emitting device 2 encapsulates especially cast now by encapsulating material 17.At this, encapsulation 17 has spherical basically profile, and this profile has smooth downside.The contact-making surface 18 of the foot 9 of LED light-emitting device 2 is exposed, also is that the contact-making surface 18 of corresponding electric terminal 9 is exposed in the zone of smooth downside.

The advantage that has of Feng Zhuan light-emitting device 2 is that especially when light-emitting device had little stretching, extension, this light-emitting device also can be used as loose mail and is applied on the supporting mass like this.Because because circular basic configuration, light-emitting device 2 can roll on supporting mass, is on the smooth downside and tries hard to keep by magnetic attachment subsequently up to it to be held on the supporting mass.When as described above, when the magnetic polarity of the contact-making surface 18 of foot was different and relevant with the related magnetic polarity of the related contact site of supporting mass, this was particularly advantageous.Be positioned on the suitable contact site of supporting mass because guaranteed 9 of foots like this, for example connect with the different terminals of (direct current or interchange) power supply.

Alternatively, the shape of encapsulation is not limited and for example can be square, sheet or columniform, and this especially can realize by corresponding cast.Encapsulation also can realize by using encapsulating shell, yet the joint of encapsulating shell is more bothersome.

Fig. 4 shows LED light-emitting device 2, and attached on the supporting mass 19, this supporting mass has two set of

contact portions

20,21, can apply electromotive force between contact site as it.The shape of first group single contact site 20 is grid-like, and the rectangle contact site 21 of the other group of other electromotive force is arranged in the gap of first contact site 20.Certainly, not being must be rectangular shape; Or rather, first group contact site 20 for example also can be a rhombus, so and wideer.In other words,

electrical contacts

20,21 is divided into two groups, and be arranged to grid pattern, wherein this grid is first group a contact site 20 and be second group contact site 21 by the face of this screen encompassing, wherein can not apply electromotive force between on the same group the

contact site

20,21.

LED light-emitting device 2 shows the contact shank 8 in the case of bending, and wherein the transmit direction of light-emitting device 2 is aimed at individually by bending.Substitute two contact shanks 8, for example can use the gooseneck that has crooked tubule, this tubule supporting or hold feed line.

Fig. 5 shows the supporting mass 22 that has concentric

annular contact site

23,24, these contact sites belong to one of two groups of having electrical potential difference therebetween respectively, wherein not on the same

group contact site

23,24 alternately, that is to say, between two adjacent contact sites, can apply electromotive force.In other words,

electrical contacts

23,24 is divided into two groups, and is provided with the circular pattern of alternately arranging with

contact site

23,24 of two groups, wherein can not apply electromotive force between on the same group the

contact site

23,24.

Fig. 6 shows supporting mass 25, it has the

contact site

26,27 of the band shape of adjacent setting, and these contact sites belong to one of two groups respectively, and these groups have electrical potential difference betwixt, wherein not on the same

group contact site

26,27 alternately, promptly between two adjacent contact sites, can apply electromotive force.In other words,

electrical contacts

26,27 is divided into two groups, and alternately arranging of the

contact site

26,27 by two groups be arranged to band pattern, wherein can not apply electromotive force between on the same group the

contact site

26,27.

Fig. 7 shows supporting mass 28, it has the

square contact site

26,27 of adjacent setting on both direction, these contact sites belong to one of two groups that have electrical potential difference therebetween respectively, wherein not on the same

group contact site

26,27 alternately, promptly extend between the

adjacent contact site

29,30 in ground and can apply electromotive force at two.In other words,

electrical contacts

29,30 is divided into two groups, and is arranged to checkerboard pattern by alternately the arranging of

contact site

29,30 of two groups.

Fig. 8 shows supporting mass 31, and it has many to contact

site

32,33, can apply electromotive force between these contact sites.In other words, every pair all has first group contact site 32 and second group contact site 33, wherein can apply electromotive force striding between the contact site of group.The advantage that this layout has is, may realize the high flexibility in the excitation of

contact site

32,33 by this layout, because every pair of

contact site

32,33 can discern well, and can have independent current terminal under extreme case, for example constant-current source.So related LED light-emitting device for example can not have special-purpose exciting bank ground to realize.

Fig. 9 shows supporting mass 34, and it has the how right contact site 35,36 that differently is shaped; 37,38 or 39,40.In other words, three pairs of groups are arranged on the supporting mass 34 with identical basic pattern, and wherein each is to the contact site 35,36 of group; 37,38 or 39,40 be of similar shape, this shape has difference between group.These light-emitting devices in this way, can use dissimilar light-emitting devices, so especially can specifically encourage and/or power with respect to group.So the contact site that for example has first pair of group of rectangle contact site 35,36 can be in the second couple who has triangle contact site 37,38 to be organized on the power supply different, that have higher supply voltage.The 3rd pair of group that has circular contact site 39,40 may differently be encouraged and/or be powered by other sources again.Alternatively or additionally, can coordinate at the terminal of the light-emitting device of same transmit feature, for example coordinate at the LED lamp of same color to the contact site of group.So, can regulate a kind of luminous intensity of color individually by encourage contact site 35 to 40 in the group selection mode.For fear of right wrong related of light-emitting device and contact site, the contact-making surface of contact site can be shaped as with related terminal and makes them only match each other.

In order to describe accompanying drawing subsequently, be suitable for following the qualification." light emitting module that can take out " means a kind of light emitting module, it can manually be installed on the supporting mass, from its taking-up or reorientate thereon, exactly, need not tool using or electrical connection lasting, that lay with hand, for example connection of setting up by screw, hinge joint, spiral wired connection device or the like needn't be arranged.A kind of material is represented in statement " magnetic material ", and it is a permanent magnet or by the strong material that attracts of permanent magnet.Illustrate that the lip-deep wording that object is installed in object comprises a kind of layout, wherein object is installed in the object, makes object surfaces have the part on surface of object or superimposed with it.Statement " LED " expression light emitting diode (" light-emitting diode ") may comprise current-limiting resistance and explain " LED ", and it is connected with light emitting diode.About 24 volts or lower of statement " low pressure " expression; All scopes outside statement " high pressure " the expression low pressure.The direction that statement " electric polarity " or " polarity " expression DC current flows, and explain the rightabout that " opposite polarity " or " other polarity " expression DC current flows.

Especially be noted that in particular with reference to the following drawings the time now: orientation of the present invention illustrated in the accompanying drawings only is exemplary with the orientation of the light of being launched, and does not have restricted feature.In many application, light is emission downwards basically.Figure 10 shows a kind of luminescent system 1010, the light emitting module 1014 that it has supporting mass 1012 and can take out.Supporting mass 1012 can be made of magnetic material such as iron fully, perhaps is made of one or more being partially embedded in this nonmagnetic substance that magnetic material constitutes nonmagnetic substance such as plastics.In the form of implementation of supporting mass material conduction, can use dielectric coat 1016 (in Figure 11, more specifically illustrating) therein so that

conductive channel

1018 and 1020 is insulated from each other, and with body 1026 insulation of supporting

mass.Conductive channel

1018 and 1020 is the conductive strips that approach, for example

copper film.Terminal

1022 and 1024 provides a kind of means that luminescent system 1010 is connected with outside electric power source of being used for.In the situation of supporting mass conduction, supporting mass can for example be used as ground as one of conductive channel therein, or rather, and especially in low pressure applications.

Light emitting module 1014 has the light source 1028 that is installed on the socket 1030.Light source 1028 has feed line 1036 and 1038, and they link to each other with 1034 with conductive path 1032, and these paths are set up and contacted with the physics of the path 10 20 of supporting mass 1012 or 1018 and electrically contact.Under different visual angles of the present invention, light source 1028 is installed on the socket replaceably, makes light source (for example incandescent lamp bulb) to be replaced after its burning time.As top referring to, can use dielectric coat 1031 (in Figure 11, more specifically illustrating) so that with conductive path 1032 and 1034 insulated from each other and with socket 1030 insulation.Conductive path 1032 and 1034 by thin conductive material for example copper film form.Socket 1030 can be made of magnetic material such as iron fully, perhaps is made of one or more being partially embedded in this nonmagnetic substance that magnetic material constitutes nonmagnetic substance such as plastics.The magnetic material of supporting mass 1012 can be a permanent magnet, and it attracts the magnetic material of socket 1030, and perhaps opposite, the magnetic material of socket 1030 can be a permanent magnet, and it attracts the magnetic material of supporting mass 1012.In two kinds of situations, polarity between light emitting module 1014 and supporting mass 1012 all must have enough intensity, so that module 1014 is remained on the supporting mass 1012 reliably, and also may be installed on the supporting mass 1012 all the time, remove or be repositioned on this supporting mass from this supporting mass for module, or rather, need not tool using or lasting electrical connection needn't be arranged.

The flexible circuit (perhaps Flexschaltung) that comprises path 10 18 and 1020 can be used as supporting mass 1012.The flexible circuit that has the attachment device of pressure-sensitive, heat conduction can need not dielectric and be applied on each MAGNETIC BASEMENT material with handling.Dielectric strength provides by the circuit material of flexibility.This supporting mass is suitable for being installed under cabinet that sheet metal constitutes or storeroom or the like especially well, perhaps is installed on the flexible magnetic recording tape.

Figure 11 shows the sectional view of the amplification of luminescent system 1010.Figure 11 shows the circuit of luminescent system 1010.As can seeing among Figure 10, electrical power is carried by conductive channel 1018 and 1020 from the source of outside.Figure 11 shows path 10 18 that electrically contacts with conductive path 1034 and the path 10 20 that electrically contacts with conductive path 1032.Path 1032 links to each other with the feed line 1036 or 1038 of light source 1028 with 1034.Dielectric coat 1031 for example the enamel of electronic product path 1032 and 1034 is electrically insulated from each other and with socket 1030 electric insulations.Traditional dielectric coat material of any amount or resistive coating material such as enamel, glass, pottery, organic insulation or glass/ceramic coating can be used in combination with the present invention.For example under the situation of ceramagnet, can not need dielectric coat at magnet that use has high resistance.Yet this magnet also must have enough thermal conductivity at its function as radiator, as following will referring to.Possibility for fear of the short circuit of supporting mass passage, width w (shown in Figure 11) between supporting mass path 10 18 and 1020 should be enough wide, even so that also prevent that path 1032 or path 1034 from contacting two passages simultaneously in module 1014 under the situation of rotation on the supporting mass 1012.

Show luminescent system 1050 about Figure 12 now, wherein path 10 18 and 1020 is arranged in the

groove

1052 and 1054 of the electric insulation of supporting mass 1062.The surface 1060 of supporting mass 1062 can be included in the dielectric coat 1016 outside

groove

1052 and 1054, so that

avoid path

1032 or 1034 and the electrically contacting of supporting mass 1062.

Dielectric material

1056 and 1058 can be formed by any suitable non-conducting material, and this material can be the material identical or different with the material of dielectric coat 1016.As above interview and like that, when

path

1032 and 1034 because the non-conductive property of supporting mass material (this supporting mass material encirclement groove 1052 and 1054) when being electrically insulated from each other,

dielectric material

1056 and 1058 can be optional.

In the form of implementation shown in Figure 19 to 21, light source 1028 is LED preferably.The LED light emitting module is light, compact, durable and with low cost usually.Basically well be suitable for glass cabinet according to LED form of implementation of the present invention, wherein the physics luminescent system is designed for compact and inconspicuous as far as possible.Supporting mass can approach, and for example is the steel of thin part, and wherein dielectric coat only is positioned under the electrical contacts.Light emitting module can have short profile, makes that whole luminescent system is desirable for being applied in the glass cabinet.Supporting mass can be structured in the surface of structure or the surface by structure makes up, and this surface is the surface of shelf, glass cabinet upside, cabinet downside or the like for example.Supporting mass has under the situation of inadequate internal volume therein, and part or all device that is used for the device of feed and/or control can therefrom be removed.

The optimum voltage that is used for driving the circuit that has a plurality of led light sources depends on the number of light source, its characteristic and at the layout of circuit and other circuit block.Electric current can depend on that the use direct current also is to use alternating current.Under the situation of led light source, the electrical power that the terminal 1022 and 1024 by Figure 19 to 21 applies is approximately 5 volts direct current, however following interview and like that, in some LED use, can wish it is alternating current.Under the situation of tungsten/Halogen lamp LED such as MR-16 lamp (this lamp uses in railway illumination usually), the voltage that applies by terminal 1022 and 1024 is about 12 volts.In each of these low pressure forms of implementation, do not exist because the

electric channel

1018 and 1020 that exposes causes the risk of electric shock.

Yet the light source of other types such as incandescent lamp, tungsten/Halogen lamp LED and fluorescent lamp are also in scope of the present invention.Can use step-down transformer so that reduce the voltage that applies by terminal 1022 and 1024 if necessary the time, for example in traditional tungsten/halogen railway illumination device like that.In the high pressure form of implementation, illuminator can be installed in the housing that has the printing opacity lid, this lid has prevented the path 10 18 of exposure and 1020 contact, or rather, have urgent breaker, when lid was opened, this urgent breaker automatically turn-offed the power by path 10 18 and 1020.

Especially in the LED form of implementation, socket 1030 and supporting mass 1026 are designed to make them to be used as radiator, and this radiator is derived enough heats from light emitting module 1028, so that satisfy the calorifics condition of work of module.Especially, magnet is used for heat is transferred to the substrate portion of supporting mass as hot path.Substrate is effective radiator.

The numerous LED that are suitable for all colours used according to the present invention can pass through Osram OptoSemiconductors company (2650San Tomas Expressway, Suite 200, Santa Clara, CA 95051) and obtain.The LED of DRAGON series is special suitable well.

But show the form of implementation of a kind of alternative of light source with reference to Figure 13.Light source 1080 among Figure 13 can be used for the light source 1028 of Figure 10, and its mode is that feed line 1082 and 1084 is electrically connected with path 10 18 or 1020.Light source 1080 comprises the cylinder-shaped sleeve 1086 that has axis A-A.The reflector 1088 that has axis A-A equally is installed in the sleeve pipe 1086.Reflector 1088 can be as shown in Figure 13 be parabola shaped like that, perhaps have other shapes arbitrarily, so that obtain desirable beam pattern.Reflector 1088 has catoptrical coating 1089 usually on inner surface.Lens 1090 can be installed on the sleeve pipe 1086 removedly by suitable device, for example install by screw thread 1092, make lens 1090 before emitting led 1096, to screw in the sleeve pipe 1086, perhaps install by the grafting on two kayser protuberances.As from known well the prior art, lens 1090 can be formed, enclose pattern and/or coating, so that produce the different qualities of the light of light source 1080 emissions.In addition, lens 1090 can be colored, and make it be matched with the color of light of light source 1080 emission or different with it.Lens 1090 can be opaque or translucent (halbopak) except the profile of alphanumeric mark or other symbols, make the image of when light source luminescent this mark of light source 1080 projections or symbol.Because lens 1090 are removable, so can be by change characteristic or the effect that lens 1090 change the light of light source 1080 emissions with other lenses.Light source 1080 uses LED 1096 as the photogenerated device in Figure 13, yet also can use other photogenerated device.But in the form of implementation of an alternative of the present invention (not shown in figures), reflector 1088 can be installed on the light emitting module removedly, the feasible direction that can regulate the beam of being launched, and need not light emitting module is repositioned on the supporting mass.The US 4,719,549 that this is for example authorized on January 12nd, 1988 in the US 5,154,509 and the Apel of mandate on October 13rd, 1992 referring to people such as Wulfman.

Figure 14 is the graphics view that is used for the supporting mass 1100 that together uses according to one or more light emitting modules of different visual angles of the present invention.The difference of the supporting mass 1012 among supporting mass 1100 and Figure 10 is that this supporting mass has how right conductive channel, and one or more light emitting modules can be installed on these passages with magnetic means.In the accompanying drawings, it is right that passage 1102 and 1104 forms first passage, and passage 1106 and 1108 forms second pair, and passage 1110 and 1112 forms the 3rd pair.If wish, then can add additional right passage to supporting mass 1100.Each passage can form and be installed on the body 1101 by material thin, conduction, and this this body and function dielectric coat covers, and as shown in Figure 11, perhaps each passage can be fixed in the groove of the isolation in the body 1101, as shown in Figure 12.Terminal 1114 can link to each other with the electric power source of outside with 1116.Conductive channel and/or passage are to making by circuit board technology.The advantage that obtains in form of implementation as shown in figure 14 is, a plurality of light emitting modules can be installed on the supporting mass, or rather, installs with the form of array basically, promptly installs in the layout of the row and column of x direction and y direction.

Supporting mass 1100 can have multiple form of implementation and application.In perpendicular alignmnet or orientation as shown in figure 14, supporting mass 1100 can be as the fixture of direction board.The light emitting module that has the alphanumeric lens can be installed on the supporting mass 1100, makes its display message.When supporting mass 1100 flatly is installed under the sales counter or is installed in the glass cabinet, wherein passage is towards the below, then supporting mass holds the flexibility layout of light emitting module, this is arranged in the x direction and locatees on the y direction, so that with light towards the working region of determining, perhaps, highlight with different light intensity, color or aesthetic effect in case of necessity so that highlight definite commodity.

Figure 21 shows one embodiment of the present of invention, and it is installed in the glass cabinet 1300.Glass cabinet 1300 has luminescent system 1303, and this luminescent system is installed on the downside of upper shelf 1302.The object 1310 that is positioned on the shelf 1312 is objects of showing after glass plate 1314.Light emitting module 1306 is installed on the supporting mass 1304, so that illuminating objects 1310 advantageously.The location of module 1306 is very flexible.As referring to reference to Figure 14, these modules can be installed in diverse location in the x direction of the storage facilities of level and y direction.As with reference to Figure 13 described, reflector 1308 adjustable grounds are installed on the module 1306, make light beam 1316 to be orientated and make them, and the different qualities of the light of being launched can be by selecting to use the lens (if any) on reflector 1308 to realize with desirable angle illuminating objects 1310.If the object that is placed on the storage facilities 1316 is illuminated, then Fu Jia illumination light-emitting system 1303 can be installed in the downside of Frame plate 1312.

Get back to Figure 14, supporting mass 1100 can be as the illuminator holding device that has a plurality of rails, and this illuminator holding device is installed on top or the wall.Preferably have the supporting mass 1100 with lid protectiveness diffusion and can be used as top light emitting body holding device.In the space at the top that has suspension, supporting mass 1100 can be designed for alternative top wallboard and be coupled in the grid of top.In addition, the different supporting masses 1100 of identical size or other sizes can together be used as construction unit or parts, so that form two dimension or three-dimensional luminescent system, for example the letter " E " shape two-dimentional system, the perhaps three dimension system of cube or parallelepiped shape or its combined shaped, wherein light emitting module is installed on some faces or on all faces.

It is rectangle that supporting mass need not.Figure 15 show based on as under supporting mass 1100 situations the view of the circular supporting mass 1120 of identical wiring principle and insulation principle.In Figure 15, the passage of each conduction illustrates by single line, rather than illustrates as the two-wire among Figure 14, so that clearly show that circuit.This accompanying drawing shows three pairs of

passages

1122 and 1124,1126 and 1128 and 1130 and 1132, and they are arranged on the concentric circles of dielectric surface 1134 of supporting mass 1120 basically.When terminal 1134 and 1136 activates with suitable electrical power, one or more light emitting modules can be installed on the function one or more passages on.In the deformation program of the form of implementation in Figure 15, some right passages are installed on the circular supporting mass with spirality rather than concentrically ringed pattern.In scope of the present invention, supporting mass 1120 and passage to be made amendment in its surface, its mode is round-shaped other different shapes, for example ellipse, the semilune or the like of being stretched as with them.

Viewpoint of the present invention also can be used for three-dimensional.Figure 16 shows based on the view as the spherical bearing body 1140 of the identical wiring principle of the supporting mass among Figure 14 1100 and insulation principle.As among Figure 15, the conductive channel among Figure 16 A illustrates as single line.Passage has

passage

1142A and 1142B to 1142; Equally, passage is made of two passages respectively 1144,1146,1148 and 1150.In this form of implementation, circuit is positioned on the dielectric surface 1141 of ball 1140 fully.Passage is the latitude circle of ball 1141 to 1142,1144,1146,1148 and 1150 basically.This circuit can activate by terminal 1152 and 1154 is linked to each other with suitable power source.

For light emitting module being installed on the spherical supporting mass 1140, the supporting mass surface must be smooth basically.Here employed statement " smooth basically " means: the supporting mass surface is smooth or has enough big radius of curvature, so that make light emitting module to be installed on the supporting mass surface by magnetic attraction, and can not slide or overturning.Distance between the right passage of each passage should be enough little, makes to carry out reliable electrical contact and thermo-contact between the respective paths of passage and the light emitting module installed.In order to make reliably electrically contacting with thermo-contact between the respective paths of supporting mass passage and the light emitting module installed become easily, the surface of light emitting module can be crooked, so as with the curvature coupling of supporting mass.As here meaning about the module employed statement in surface " smooth basically ": the module surface is smooth or crooked, make this module to be installed on the supporting mass surface and not slide or overturning, though the curvature on supporting mass surface and module surface might not be identical by magnetic attraction.In addition, can improve the supporting mass passage with respect to the surface of supporting mass, as shown in Figure 11, and/or the module path can be improved about module body.Additionally, this module can comprise elastic contact part, and it is typically formed by beryllium copper, and these elastic contact parts can be shaped as and make the curvature coupling of they and supporting mass.Elastic contact part has improved the heat transmission of leaving from module, and module stability has been improved at the position that especially path between module and supporting mass/the passage contact site is narrow.Appropriate combination by using aforementioned technology makes it also can be installed on the supporting mass reliably with magnetic means under the situation of the surface curvature of supporting mass even light emitting module can be configured to.

Though Figure 16 A shows spherical supporting mass, yet identical principle also is applicable to the supporting mass of columniform or taper and the three-dimensional supporting mass of other bending.Especially, can be advantageously in three-dimensional form of implementation of the present invention, weight is by using following supporting mass to obtain: this supporting mass has nonmagnetic substance such as plastics, and wherein the piece that constitutes of magnetic material is embedded in the supporting mass or on the inboard attached to supporting mass.In this form of implementation, the quality of the magnetic material that embeds must be enough big, so that satisfy heat sinking function, and as of the present invention all use the situation in the form of implementation of heat-sinking capability of magnetic materials, the size of the contact-making surface between supporting mass and module must be enough, transmits so that can realize the sufficient heat from module to supporting mass.

Figure 16 B is to show identical spherical bearing body 1140 the whole latitude circles on the dielectric surface 1141 of ball 1140 except passage to 1142,1144,1146,1148 and 1150.In this form of implementation, terminal 1152 and 1154 extend into the inside of supporting mass 1140.Under the situation that otch in passing this accompanying drawing is seen, the right first passage of terminal 1152 and each passage is electrically connected, as by shown in the connecting line 1156,1158 and 1160 like that.The right second channel of terminal 1154 and each passage is electrically connected, as by shown in the connecting line 1162,1164 and 1166 like that.Additional connecting line to rest channels in Figure 16 B for clearly former thereby omit.Revise supporting mass 1140 in scope of the present invention, its mode is that this supporting mass is pulled into different other shapes such as ellipsoid.In the deformation program of the form of implementation in Figure 16 A, single right passage is formed on the lip-deep spirality of ball 1141, and this spirality extends to the South Pole from the arctic basically.The form of implementation of Figure 16 A and 16B is used in following luminescent system usually, and these luminescent systems hang on the top or are installed on the shaft-like socket.For the level of being directly installed on or vertical lip-deep luminescent system, can use half of supporting mass 1140, i.e. hemisphere, or rather, by using the same principle as shown in Figure 16 A and 16B.

Figure 16 B shows following scheme: electrical power can provide to the supporting mass passage from the supporting mass inside of luminescent system.Different controller for electric consumption such as ballast, light modulator, transformer, electrical network parts, inverter, driver, controller or the like can be arranged in the body of supporting mass equally, make luminescent system can be directly with reference power supply, for example link to each other with 110 volts alternating current.In addition, this control device can be controlled one or more light emitting modules respectively, for example controls the ballast of four or eight fluorescence-light emitting modules.This feature of the present invention can for example cube, ball or polyhedron together use with three-dimensional supporting mass, and also can with two-dimentional supporting mass as together using at the supporting mass as shown in Figure 10,14 and 15, or rather, its mode is that electric channel prolongs up to supporting mass body inboard, rather than directly extend to outside terminal, as shown in this accompanying drawing.

Under other viewpoints of the present invention, Figure 17 A and 18A show the additional examples of the form of implementation of three-dimensional supporting mass.Figure 17 A shows the icosahedron supporting mass 1180 that has 20 identical faces 1182, and wherein each face all is an equilateral triangle, as shown in Figure 17 B.Having dual electric insulated terminal 1181 extends in the body of supporting mass 1180 and provides a kind of and be used for electrical power from the means of supporting mass 1180 delivered inside to light emitting module.Figure 18 A shows the 12 surface bearing bodies 1190 that have 12 identical faces 1192, and wherein each face all is equilateral pentagon, as shown in Figure 18 B.Having dual electric insulated terminal 1191 extends in the body of supporting mass 1190 and provides a kind of and be used for electrical power from the means of supporting mass 1190 delivered inside to light emitting module.As shown in this accompanying drawing, the passage 1184 and 1186 of conduction can be centrally located on the gore 1182 of dielectric coating, and the passage 1194 and 1196 of same conduction can be positioned on the pentagon face 1192 of dielectric coating, though the aligning of these passages in triangle or pentagon face is not to be conclusive.Face 1182 and 1192 has magnetic material, makes light emitting module to be installed on any.Passage 1184 and 1186 be electrically insulated from each other and with face 1182 insulation, and same passage 1194 and 1196 and face 1192 electric insulations.Passage 1184 and 1186 passes face 1182 and is connected with terminal 1181, make electrical power to carry in the identical mode as shown in Figure 16 B, and same content is applicable to the passage 1194 and 1196 of the inside of 12 surface bearing bodies 1190 from the body interior of icosahedron 1180.

Can make up by using aforesaid same principle by those skilled in the art according to the combination of the additional solid shape of the supporting mass of different points of view of the present invention such as cylinder, cone, prism, different spaces form and end (Stuempfe) or the like.These additional forms of implementation are all in scope of the present invention.

As described in the example in front, the multiple form of implementation of supporting mass structure and deformation program are possible and are practical.Importantly, the power path of light emitting module correctly is positioned on the electric channel of supporting mass in all these forms of implementation, makes that light emitting module can be by feed reliably.Can use demonstration and figure to provide for guidance with module correct aligning on supporting mass.Figure 19 shows the luminescent system among Figure 11, and it has

additional protuberance

1206,1208 and 1210 and holding tank 1212.Save in hypothesis under the situation of protuberance 1210 and groove 1212, when

protuberance

1206 and 1208 has guaranteed that light emitting module 1200 is on being installed in supporting mass 1204 correctly electricity aim at, may be except electric polarity.Under situation about protuberance 1210 being positioned in the groove 1212, guaranteed correct polarity, because the two protuberance and groove of all being positioned at the center line B-B right side of this accompanying drawing are not medially on supporting mass 1204.Be noted that protuberance 1210 and groove 1212 are not is essential or desirable all the time, as for example therein in the light emitting module 1200 usefulness alternating currents situation about driving.

Therein in the direct current form of implementation that light source 1214 is removed for LED and protuberance 1210 and groove 1212, the user can notice that light emitting module is by the polarity installation with mistake, exactly, not luminous when it is switched on based on the following fact: LED, the user can install light emitting module with opposite polarity again subsequently.Alternatively, light emitting module can comprise two LED, and wherein each LED is next luminous with different polarity, and making this module have which kind of polarity all has a LED luminous.The light emitting module of LED with two opposite polarities is with alternating current work.Another pair LED alternative scheme is a kind of light of each LED emission different colours, and for example a LED launches white light and has the 2nd LED emission red light of opposite polarity.The red light of being launched can be signaled user's light emitting module and be installed with the polarity of mistake, and perhaps the extension feature of light emitting module can be: this light emitting module can according to its on supporting mass the polarity position or launch the light of different colours according to the polarity that offers luminescent system.Latter event can use in signal system, because the color of the light of being launched (for example red or green) can change by the polarity inversion that will offer luminescent system.Additional signaling is selected for example, and flicker can realize by the pulse of the power that offers luminescent system.Single light emitting module can be made of two groups of LED, wherein one group for first polar reaction that is applied, and second group for the opposite polar reaction that is applied, perhaps alternatively, luminescent system can use two groups of light emitting modules, wherein a pack module is for first polar reaction, and second pack module is for the opposite polar reaction that is applied.

Figure 20 shows the luminescent system among Figure 12, and it has at additional protuberance 1222 and the holding tank 1224 in light emitting module 1228 and its coupling on the supporting mass 1226.Protuberance 1222 is asymmetric, and wherein this protuberance has vertical side (left side in the accompanying drawings) and inclined side (right side in the accompanying drawings), and same content also is applicable to the groove 1224 with its coupling.Module 1228 is installed in (wherein protuberance 1222 correctly is positioned in the groove 1224) guaranteed reliable electrical contact and correct polarity on the supporting mass 1226, and whether tube seat is not aimed at medially about center line C-C.There is the multiple possible setting of protuberance, groove and/or other devices in different points of view according to the present invention, is installed on the supporting mass with correct electric polarity with the reliable electrical contact between module and the supporting mass and (when measuring) so that guarantee light emitting module.
