[Prior Art] An existing track lighting system is set to position a light-emitting element at a specific position ' while supplying electric energy to that position. One of the benefits of such a system is that the light-emitting elements can be positioned in multiple locations along the track, thereby providing a level of customization. While these existing systems work well with incandescent light sources, new, more efficient LED-based light sources require better thermal control because the life of the LEDs tends to decrease with increasing temperature. In addition, conventional track lighting systems tend to be too large due to the size of incandescent light bulbs. Therefore, a lighting system that can provide an elegant and aesthetically pleasing installation method to solve thermal, electrical, and structural problems will be appreciated by a specific group of people. [New Content] An energy consuming device includes a housing that supports one or more magnets and first and second terminals. An energy consuming module is supported by the housing, and the energy consuming module may comprise an array of light emitting diodes. A cover can be used to secure the member to the housing. A thermal bridge extending below the base of the housing may be provided. The one or more magnets are used to secure the energy consuming device to a way to support the power contact. The first and second terminals engage the power contact.

In general, the illustrated embodiments will be directed to low voltage applications (such as 12_). 24VAC/DC). In some applications, the voltage will be dc (which makes it easier to drive many types of components that require a DC power supply). However, it is also possible to provide 12V AC. In this case, for each energy consuming device, if it requires DC power, it will need to include power conversion devices such as rectification β and capacitors. Additionally, it can be appreciated that multiple energy consuming devices can be placed on a single track in the manner discussed below. Additionally, the two tracks can be placed adjacent to each other and the first and second jumper devices electrically connect the power contacts on the two tracks together.

Structure (not shown). The energy consuming device 2 can be an LED device. It will be appreciated that the illustrated embodiment is suitable for use in a track lighting application because the energy consuming package is simply positioned, mounted, and moved back and forth along the truss structure 22. The energy consuming device 2 and the support structure 22 can be used in many applications such as, but not limited to, on the vehicle for pillar illumination and for the workshop. The illustrated embodiment is also suitable for use in many other applications, such as more general illumination, and is believed to be particularly well suited for applications requiring flexibility.

The fulcrum structure 22 can be easily mounted to a support surface such as a wall, ceiling, cabinet, or the like. However, it should be noted that the support surface can be of any desired shape and can even be configured to allow a socket-like shape or some other configuration on which a single energy consuming device is mounted. Moreover, if desired, the support surface can be recessed within the housing (which is understood to be provided by other structures by heat dissipation provided by the way). As shown, the track 24 is comprised of a bottom wall 30 (shown as flat) and side walls %, 34 extending perpendicularly from opposite edges of the bottom wall 30, preferably the two side walls 32, The spacing between 34 is less than 6 〇μ.

The track % is electrically conductive and may also be electrically conductive, and if electrically conductive, the pair of elongated power M443121 contacts 26, 28 are electrically insulated from the track 24 via a suitable insulator 37, such as insulator 37. It is a non-conductive double-sided tape, paint or anodic oxide disposed on the track 24. The track 24 can be formed from extruded plastic that has been electroplated (e.g., plated with nickel and tin), the track 24 can be formed entirely of metal, or can be a hybrid combination of plastic and metal. Although the side walls %, 34 are not perpendicular to the bottom wall 3, it should be understood that in some embodiments, the side walls 32, 34 may be eliminated or may be angled relative to the bottom wall 3. The energy consuming device 20 is disposed on the bottom wall 3 and the power contacts %, 28. The rail 24 can function as a heat sink for the energy consuming device 2 as described herein.

It can be a decorative cover %, which is positioned on the casing 38 and covers the energy consumption module 4 and the magnets and the core. As is known in the art, a lens or other light styling element 48 can be provided and can be supported by the body 38 and/or the cover 46 to receive the energy consuming module 4 (if δ history is LED) The light of the array is guided. The housing 38 can take a variety of shapes, such as a circular shape as shown in Fig. 1, a rectangle, a square, a triangle, an ellipse, and the like as shown in Fig. 2. The housing "comprising a base portion 50' has an inner surface 52 and an outer surface 54; - a bore 56 extending through the base portion 50; and magnet holders 58a, 58b disposed at each end of the base portion 50 and separated by a center bore 56; First and second terminal apertures 6〇a, 6〇b and their associated, sub-62a, 62b. It should be noted that although shown as a dual magnet holder, in an embodiment, housing 38 may be additional The manner is configured to provide a single magnet holder. For example, but not limited to, one end of the housing 38 can be retained via the lip provided by the support structure 22 and then a single magnet holder and associated magnet will be sufficient to securely position the suction body 38. Alternatively, A magnet holder can be located centrally on the housing 38 such that forces are evenly distributed across the ends (and if included). A portion of the energy consuming module 4A extends through the base 50 via the aperture 56. The magnet 42a Placed in the magnet holder 58a; the magnet 42b is disposed in the magnet holder 58b. The magnets 42a, 42b are shown as being rectangular in cross section to facilitate the manufacture of the element, however, other various shapes of magnets may be employed. 42a' 42b. Each magnet holder 58a, 58b is formed as a recess extending from the inner surface 52. Each of the magnet seats 58a, 58b has a plurality of side walls 64 extending from the inner surface 52, and an interface wall 66. Each of the magnet seats 58a, 5 is preferably coupled to the magnets 42a, 42b. The shapes are uniform and the magnets 42a, 42b can extend from the inner surface 52 of the housing 38 or be flush with the inner surface 52 of the housing 38. The cover 46 can take a variety of shapes to accommodate the energy consuming module 4 〇 and optional optics 48. For example, without limitation, the cover 46 may be completely flat, and the cover 46 may also be substantially flat and have a raised central portion to accommodate the M443121 nano optics 48. And the cover 46 can also be concave or convex. The illustrated cover 46 includes a cover wall 68 having an inner surface 70 and an outer surface 72; a hole through the center of the cover wall 68, the lens Or other light modeling elements 48 are mounted in the apertures; magnet holders 74a, 74b are disposed at each end of the cover wall 68 and are separated by the central aperture; and side walls 75a, 75b, 75c, 75d, from the cover wall The edge of 68 extends. When the cover 46 is placed on the housing 38, the magnet 42a is held in the magnet holder 74a, the magnet 4 2b is retained in the magnet holder 74b and the side walls 75a, 75b, 75c, 75d are mated with the edges of the housing 38. Each of the magnet holders 74a, 74b has a side wall 76 extending from the inner surface 70 while the inner surface 70 forms the recess The bottom wall. A portion of the side walls 75b, 75d form part of the respective magnet holders 74a, 74b. However, it will be appreciated that although the side walls 75b, 75d of the cover 46 are shown as part of the magnet holders 74a, 74b, A separate wall may be provided on the cover 46 to form the remainder of the magnet holders 74a, 74b. Each of the magnet holders 74a, 74b preferably conforms to the shape of the magnets 42a, 42b. Thus, it can be appreciated that the magnets 42a, 42b are sandwiched between the inner surface 70 and the interface wall 66 and are thereby retained in position. Additional constraints are provided by the side walls 76, 75b, 75d, however, any desirable constraints are suitable. For example, the magnets 42a, 42b are attached using an adhesive or other fastening system. The benefit of retaining the magnets 42a, 42b between the housing 38 and the cover 46 is that manufacturing costs can be reduced. As shown, the energy consuming module 40 is configured as a solid state lighting element that includes a plate 78 that is disposed on the board 78 and protected by the cover 80. The plate 78 can be a thermally conductive material, such as aluminum covered with an insulating layer 8 M443121, on which the array of LEDs is placed. Alternatively, if the energy consuming module 4G is less sensitive to thermal decay, the board % may be a circuit board or some other composite structure. (d) 82 (which may be, but is not limited to, a thermal pad or a thermal paste) may be disposed on the outer surface of the energy consuming module 4 (e.g., on the lower surface of the plate 78). Thermal bridge 82 can be a thermally conductive adhesive gasket such as, for example, 3μ thermal tape 8810. As shown, the thermal bridge 82 connects the plate 78 to the bottom wall 3 〇° as shown, since the plate 78 is configured to have a lower thermal resistance between the plate 78 and the LED array (preferably The plate will have a thermal conductivity greater than 50 watts/buy-Kelvin (w/(m κ)), and more preferably will have a thermal conductivity greater than 100 W/(m Κ), and the thermal bridge 82 will effectively The plate 78 is joined to the bottom wall 30 and the total thermal resistance between the LED array and the bottom wall % will be less than 3t:/W and preferably less than 2t/w. In addition, if the thermal bridge 82 is kept thin and a material having a relatively high thermal conductivity is selected, the total thermal resistance can be made lower than 1 c /W. For example, this design is feasible if a bridgelux LED array is used in combination with a suitable thermal bridge and sufficient force is applied by the magnets 42a, 42b. Thus, it will be appreciated that the illustrated design generally allows for a magnetic support energy consuming device 20 having a very efficient heat transfer design that allows for use on lighting fixtures having a brightness greater than 5 〇〇 lumens while also having very A compact interface having a thermal resistance of less than 3 ° C/W and preferably less than 2 t/W and having a potential below rc/w. The plate 78 is placed in the recess 83. The recess 83 surrounds the central opening 56 such that the plate 78 is generally flush with the lowermost outer surface of the housing 38. The terminal hole 60a is adjacent to the magnet holder 58a but spaced apart from the magnet holder 58a; the terminal hole 60b is also close to the magnet holder 58b but spaced apart from the magnet holder 58b. The terminal 9 hole 60a is adjacent to one edge of the base 5〇 and the terminal hole 6 is adjacent to the other opposite edge of the base P 50 . Each of the terminal holes 6A, 60b extends from the inner surface 52 to the outer surface 54 through the base 5'.

The second portion 86 extends from the respective first portion 84 and is angled relative to the corresponding first portion 84. The second portion % extends through the respective terminal holes 6〇a, 6〇b. The third portion (10) extends from the corresponding second portion % and is further engaged with a power contact. Each third portion is curved and extends outwardly from the outer surface 54. The second portion % and the third portion 88 can The first portion 84 is flexed relative to the first portion 84 such that the third portion 88 is suitably engaged with the -electric contact in the range of the flexing distance. In one embodiment, the first. the trowel 86 and the second portion 88 are The flexing range has an allowable range of at least 0.4 mm. The terminals 62a, 6沘 pass through the mounting portion to the base 50 (e.g., solder) and via a conductive line 89' disposed on or within the housing % Thereby electrically connected to the energy consuming module 4, such as the anode or cathode of the array. In one embodiment the cover 46 and the base % can be set to surround the second portion of the terminals 62a, 62b and the periphery of the third portion 88 The mouthpiece is opened in such an embodiment, a cover 46 is mounted to the housing 38. The cover 46 extends over the magnets 42a, 42b to shield the magnets 42a, 42b. And the cover 46 forms a sealed beam between them to block Or dust further enters the assembly via the aperture %. In one embodiment, this can be accomplished by tightly controlling the mating clearance between the 10 M443121 housing 38 and the cover 46. In another embodiment, The evanescent seal can be achieved by using a gasket to "press the cover 46 against the base 50 such that the terminals 62a, 62b are sandwiched between the cover 46 and the housing 38 in that the clamping force is provided for the terminal 62a. Further support of the first portion 84 of 62b is fixedly positioned, which makes it difficult for any other pressure acting on the first portion 84 to cause damage to the joint between the base 50 of the energy consuming device 20 and the terminals 62a, 62b. Placed on the support structure 22 such that the magnets 42a, 42b are between the two electrical contacts 26, 28 and proximate to the bottom wall 30 of the track 24. The magnetic attraction between the magnets 42a, 42b and the track 24 provides for energy dissipation. The force of the device 20 is fixed to the track 24. The interface wall 66 is preferably thin enough so as not to interfere with the aforementioned magnetic forces. If desired, a hole 'through each interface wall 66 can be provided to allow the magnet portion to extend through the interface wall 66. In general, the apertures 82 may not be provided in the interface wall 66. The thermal bridges 82 are positioned on the bottom wall 3〇 between the electrical contacts %, 28 and may fill any space between the plates 78 and the bottom wall %. There is a lower thermal resistance between the plate 78 and the bottom wall 3A. Depending on the size of the energy consuming device 20, an air gap may be provided between the interface wall 66 and the rail 24 as long as the air gap does not adversely affect the aforementioned magnetic force. The terminal 62a is mated with the power contact 26; the terminal 6 is mated with the power contact 28. The terminal - (4) is flexed with the power contact [Μ, the first portion 84 is flexed. This will ensure that the terminal 62a, 62b ^ The two portions 86 and the third portion 88 can have good electrical contact with the power contacts 26, 28 within their tolerance range. During operation, 'electric power (P〇wer) flows through the power contacts 26, 28, 11 M443121 through the terminals 62a, 62b, along the conductive line 89 to the energy consuming module 4 (the heat generated by the energy consuming module 40 must be dissipated (Otherwise the life of the energy consuming device will be reduced.) The heat generated by the energy consuming module 40 is transferred to the bottom wall 30 via the thermal bridge 82. The track 24 acts as a heat sink. The fins 36 are not required, but may It is used to provide additional heat dissipation area. Of course, the obstruction 24 (and optional fins 36) can be designed in any shape according to the appropriate decorative design. The magnetic is overcome by the user pulling the energy consuming device 20 away from the support structure 22. The force, energy consuming device 20 can be easily moved back and forth over the support structure 22. The energy consuming device 20 can then be easily repositioned on the support structure 22. If the thermal bridge 82 is placed on the energy consuming device 2, it is desirable to have sufficient The force to ensure a reliable thermal connection between the energy consuming device 20 and the support structure 22. The magnet 42a' 42b provides this force while avoiding moving (e.g., rotating or sliding) the energy consuming device 20 during installation (if the thermal bridge 82 Compliance Having an adhesive property or deforming during such movement would be an advantage. In the illustrated embodiment, the attraction between the magnets 42a, 42b and the track % provides a minimum of 3 psi (0.021 MP), Preferably a pressure of 5 psi (〇〇 34 Mp ), and more preferably 10 psi (0_069 MP), is beneficial to provide a reliable thermal connection. However, the amount of beneficial force depends on the mass of the energy consuming device 2 , the amount of heat that needs to be dissipated, and the attachment to The efficiency of the heat sink of the energy consuming device 2〇 is as shown in FIGS. 7 to 15. The power supply module 120 is disposed on the flat bottom wall 3〇 and the power contacts 26 and 28. The power supply module 12 includes : a lower dielectric body 139 on the lower dielectric housing, the power supply 140, 12 from the lower dielectric housing 138 and extending through the upper dielectric housing 139. An oblique and basket i, the pair of magnets 142a, 142b, Supported between the lower dielectric housing 138 and the upper dielectric on the "electrical body 139; and a pair of terminal coffee, secret 'supported by the lower dielectric housing 138. The dielectric cover 146 is positioned in the lower body 138 and the upper dielectric housing 139 and cover the power source, the magnet (4) ugly, 142b and the pair of terminals 162a, 162b. The upper dielectric housing 138 includes: a generally flat bottom wall 150' having an inner surface 152 and an outer surface 154; magnet holders (10), (d) disposed on opposite sides of the bottom wall 15A; and first and second terminals The holes 16A, 16B and their associated 162a 162b. The power source 140 is disposed within the recess 156 in the bottom wall 150. The magnet 142a is disposed in the magnet block 158a and the magnet 142b is disposed in the magnet block 158b. As shown, the magnets 142a, 142b are preferably rectangular in cross-section for ease of manufacture, however, other shapes for the magnets 142a, 142b are also contemplated, and unless otherwise stated, The shape is limited. Each of the magnet holders 158a, 158b is formed as a recess extending from the inner surface 152. Each of the magnet holders 158a, i58b has a plurality of side walls 164 extending from the inner surface 152 and a flat bottom wall 166. Each of the magnet seats 158a, 158b preferably conforms to the shape of the magnets 142a, 142b, and the magnets 142a, 142b may extend from the inner surface 152 of the lower dielectric housing 138 or may be associated with the lower dielectric housing 138 as shown. The inner surface 152 is flush. The terminal hole 160a is close to the magnet holder 158a but spaced apart from the magnet holder 158a; the terminal hole 160b is close to the magnet holder 158b but spaced apart from the magnet holder 158b. The terminal hole 160a is adjacent to one side edge of the bottom wall 150, and the terminal hole 160b is adjacent to the opposite other side edge of the bottom wall 150. Each of the terminal holes 160a 13 , 16〇b extends through the bottom wall 150 from the inner surface 152 to the outer surface 154. As is apparent from FIG. 14 at», each of the terminals 162a, 162b is formed of a conductive material and has: a flat base 184; a first P blade 186 extending from the base 184, a second portion j88, and a third portion 19 〇; and a pair of concentrating portions 192, 194. The bases 184 of the respective terminals i62a, 162b are disposed in the recesses 196a, 196b in the inner surface 152 of the bottom wall 150 that are adjacent to the respective terminal holes 160a, 160b. The first portion 186 extends perpendicularly from the base 184. The second portion 188 extends from the respective first portion 186 and is at an angle relative to the respective first portion 186. The third portion 19 extends from the corresponding second portion 188 and is generally perpendicular to the corresponding first portion 186. Each of the third portions 190 is curved and extends through the respective terminal holes 16a, 16b. The third portion 190 extends outwardly from the outer surface 154. The second portion 188 and the third portion 19 can flex relative to the first portion 186. Preferably, second portion 188 and third portion 190 have a flex tolerance range of at least mm 4 mm, as will be discussed in more detail below. The hub portions 192, 194 are connected to wires or blade switches (not shown). The terminals 162a, 162b are electrically connected to the power source 14A via conductive lines disposed on the inside or the inside of the lower dielectric case 138. Alternatively, the terminal 162a' 162b may be coupled to the power source 140 via an insulated conductor (e.g., an insulated wire). The upper dielectric housing 139 is disposed over the lower dielectric housing 138 and covers the magnets 142a' 142b and the terminals 162a, 162b. The upper dielectric housing 139 can include an aperture 199 through itself to allow the power source 140 to pass therethrough. When the upper dielectric housing 139 is placed over the lower dielectric housing 138, the magnets 142a, 142b are ignited between the lower dielectric housing 138 and the upper dielectric housing 139. The cover 146 14 M443121 concealed the 'I I shouting body 138 and the upper dielectric housing 139 and properly attached thereto. The power module 120 is mounted on the support structure 22 with the magnets 142a, 14A disposed above the power contacts 26, 28 of the track 24. The magnetic attraction between the magnets 142a, 142b and the track 24 provides the force to secure the power module 120 to the track 24. The bottom wall 166 is sufficiently thin to not interfere with the magnetic force. Terminal 162a is mated with power contact 26; terminal 16A is matched to power contact μ. When the terminals 162a, 162b are engaged with the power contacts 26, 28, the second portion 188 and the third portion 190 flex relative to the first portion 186 within their tolerances. This ensures good electrical contact between the terminals 162a, 162b and the power contacts %, 28. It will be appreciated that during operation, current flows from the power source 140 along the wires or conductive lines connected to the contacts i6a, 1626, through the contacts 162a, 162b to the power contacts %, M, and then to the energy consuming device. 20. As noted above, the terminals are capable of flexing within a range and flexing within about 1 mm as described while still providing reliable electrical contact. While a smaller tolerance range is more appropriate for some applications, it has been confirmed that an allowable range of greater than 0.5 mm and preferably greater than 〇8 mm is beneficial to ensure a support surface provided on the support structure 22 (such as the bottom wall 30). Good thermal contact is formed between them. This is because, when (4) M bridges, it is beneficial to ensure that the terminals are engaged with the power contacts. Once the electrical connections are made, the focus of the consideration is to ensure that the thermal bridge can provide a better thermal interface. . This may involve making the thermal bridge have some compression range _. By allowing the material to flex within the scope of the disclosure while still providing a good electrical connection, one-to-one quantity and one 15 M443121 control various tolerances while still ensuring low thermal resistance (this is beneficial for energy consuming devices to be obtained) Longer lifespans will become easier. This allows the thermal bridge to provide higher thermal conductivity while providing less compressibility. The power module 120 can be easily moved back and forth on the support structure 22 by the user pulling the power module 120 away from the support structure 22 to overcome the magnetic force. The power module 120 can then be easily repositioned on the support structure 22. Alternatively, the lower dielectric housing 138 and the cover 146 can include ears 200, 202 through which fasteners (not shown) can securely attach the power module 120 to the track 24. If the power supply module 120 is fixed to the support structure 22 using the outer ear portions 200, 202 as shown, the magnets 142a, 142b can be omitted. While the magnets 142a, 142b are shown disposed above the power contacts 26, 28, it will be appreciated that the magnets 142a, 142b can be disposed on the lower dielectric housing 138 such that the magnets 142a, 142b are disposed in the electrical contact 26, 28 above the track 24. However, for rails 24 that are not ferrite based materials and power contacts 26, 28 are ferrite based materials, it may be beneficial to position magnets 142a, 142b above power contacts 26, 28. Jumper device 320 is shown in Figures 14 and 16-18. Jumper device 320 provides a means for attaching one support structure 22 to another support structure (not shown). Jumper device 320 is disposed above bottom wall 30 and power contacts 26, 28. The jumper device 320 includes: a dielectric housing 338; a pair of magnets 342a, 342b supported within the dielectric housing 338; a pair of terminals 362a, 362b and a dielectric cover 346 to which the dielectric cover 346 is attached The dielectric housing 338 covers the magnets 342a, 342b and the terminals 362a, 362b. The 16 M443121 electrical housing 338 includes a bottom wall 350 that is planar in shape, having an inner surface 352 and an outer surface 354; two magnet seats 358a, 358b disposed on opposite sides of the bottom wall 350; And second terminal holes 360a, 360b and their associated terminals 362a, 362b. The magnet 342a is disposed in the magnet holder 358a, and the magnet 342b is disposed in the magnet holder 358b. As shown, the magnets 342a, 342b may be rectangular in cross section for ease of manufacture; however, other shapes for the magnets 342a, 342b are also suitable. Each of the magnet seats 358a, 358b is formed as a recess extending from the inner surface 352. Each of the magnet seats 358a, 358b has a plurality of side walls 364 extending from the inner surface 352 and a flat bottom wall 366. The outer shape of each of the magnet seats 358a, 358b preferably conforms to the shape of the magnets 342a, 342b, and the magnets 342a, 342b may extend from the inner surface 352 of the dielectric housing 338 or may be flush with the inner surface 352 of the dielectric housing 338. . The terminal hole 360a is close to the magnet holder 358a but spaced apart from the magnet holder 358a; the terminal hole 360b is close to the magnet holder 358b but spaced apart from the magnet holder 358b. The terminal hole 360a is adjacent to one side edge of the bottom wall 350, and the terminal hole ® 360b is adjacent to the opposite side edge of the bottom wall 350. Each terminal aperture 360a, 360b extends through the bottom wall 350 from the inner surface 352 to the outer surface 354. The terminals 362a, 362b may be identical in construction to the terminals shown in Figure 14, so the details are not repeated here. The bases 384 of the respective terminals 362a, 362b are disposed in the recesses 396a, 396b in the inner surface 352 of the bottom wall 350 that are adjacent to the respective terminal holes 360a, 360b. Each of the third portions 390 extends through the respective terminal holes 360a, 360b and extends outwardly from the outer surface 354. The hub portions 392, 394 are connected to a wire or knife switch (17 M443121 not shown) connected to the power supply module 120 or a wire/knife switch extending from the adjacent energy consuming device 20. A dielectric cover 346 is disposed over the dielectric housing 338 and conformably attached to the dielectric housing 338. A dielectric cover 346 is placed over the magnets 342a, 342b and the terminals 362a, 362b. When the dielectric cover 346 is placed over the dielectric housing 338, the magnets 342a, 342b are sandwiched between the dielectric cover 346 and the dielectric housing 338. The jumper device 320 is placed on the support structure 22, and the magnets 342a, 342b are disposed above the power contacts 26, 28 of the track 24. The magnetic attraction between the magnets 342a, 342b and the track 24 provides the force to secure the jumper device 320 to the track 24. The bottom wall 366 is sufficiently thin to not interfere with the magnetic force. Terminal 362a mates with power contact 26; terminal 362b mates with power contact 28. When the terminals 362a, 362b are engaged with the power contacts 26, 28, the terminals 362a, 362b can flex within their tolerances. This will ensure good electrical contact between the terminals 362a, 362b and the power contacts 26, 28. In fact, two jumper devices 320 can be used to power two adjacent tracks 24. During operation, current flows from power source 140 to terminal 162a' 162b, power contacts 26, 28 along first track 24, through terminals 362a, 362b of first jumper device 320, along junctions 192/392, 194 A wire or knife switch between /394, through the terminals 362a, 362b of the second jumper device 320, to the power contacts 26, 28 of the second track 24 (and subsequently to any cost mounted on the second track 24) Can be installed). The magnetic force is overcome by the user pulling the jumper device 320 away from the support structure 22, and the jumper device 320 can be easily attached to or detached from the support structure 22. While the magnets 342a, 342b are shown positioned above the power contacts 26, 28 18 M443121, it will be appreciated that the magnets 342a, 342b may be disposed on the dielectric housing 338 with the magnets 342a, 342b positioned on the track 24. Above the bottom wall 3〇 (eg, between the electrical contacts 26, 28). It will be appreciated that the energy consuming device 20, the power supply module 12A, the jumper device 320, and the support structure 22 are all configured to provide a low profile system. This is beneficial in many situations, such as when the space is shallow. To this end, the flat bottom wall 30 and the fins 36 are extended from the bottom wall 30 by at least twice the distance from the bottom wall 30 of the electrical contacts 26, 28, together with a small relatively compact energy consuming device. Together, the disclosed embodiments present a succinct and elegant decorative appearance that is confirmed to be desirable and feasible. If the fins 36 extend over the bottom wall 30 by more than twice the power contacts 26, 28, the appearance would be more desirable, and if the fins 36 extend up to four times greater than the power contacts 26, 28, then Preferably. Additionally, the top of the energy consuming device 2A can extend to at least five times the height of the electrical contact 26'28 while the bottom wall 3's between the electrical contacts 26, 28 are engaged with the thermal bridge 82. For example, if the power contacts 26, 28 extend over the bottom wall 30 by about 66 mm, the top of the energy consuming device 20 can be between 6 〇mm and 1 〇mm above the bottom wall 3〇 (eg, greater than 5 times) The height is less than 2 times the height to provide a beneficial aesthetic appearance). For example, referring to Figures 19 and 20, system 10 is disclosed as including an energy consuming device 2〇1 mounted to track 24'. It will be appreciated that when installed, the energy consuming device 20' extends a height above the bottom wall 30' and the track 24 has fins 34 that extend a distance D2 above the bottom wall 30'. In some implementations, D2 will be greater than 1/2 D1 and greater than D1 as shown. 19 can be recognized, the interface wall 66' of the housing is positioned on the electrical contact 28. The upper plate 78' presses the thermal bridge 82 between the plate 78 and the bottom wall %. The power contact 28 from the bottom wall 3〇, the distance extending upward should be kept short, so that for an attractive and elegant appearance, the distance D2 should be at least three times the distance, preferably 〇2 should be D3 More than 1〇. The appearance of the design will be important when the component application is visible. Especially in a commercial environment, the appearance of the final embodiment will affect the behavior of those who see the design.
