Description

Technical Field

[0001] The present invention relates to a lighting device, and more particularly to a rail lamp.

Background Art

[0002] FIG. 1 shows an example of a conventional rail lamp described in Patent Document 1. As shown in the figure, this conventional rail lamp 11 is attached to a rail assembly 10. The rail assembly 10 has a rail 101 and two electrical connection plates 102 attached inside the rail 101. A rail groove 104 and two engaging grooves 103 communicating with the rail groove 104 are formed inside the rail 101. The rail lamp 11 has a connect means 111 and a lamp means 112. The connect means 111 has a main body 113, a holding column 114 extending upward from the upper surface of the main body 113, two connection terminals 115 extending from the holding column 114 to both sides respectively, and two engaging plates 116 disposed adjacent to each connection terminal 115 (from the illustrated angle, only one connection terminal 115 and one engaging plate 116 are shown, and the other one is hidden on the back side). Further, the lamp means 112 and the main body 113 of the connect means 111 are connected by a pipe 117 made of a material that can be bent and deformed.

[0003] When mounting this rail lamp 11 on the rail assembly 10, first, the holding column 114 is inserted into the rail groove 104, and then the rail lamp 11 is rotated horizontally by 90° so that each engaging plate 116 is fitted into each engaging groove 103 formed in the rail assembly 10. However, since the volume of the rail lamp 11 is large, there is room for improvement from the perspective of miniaturization.

[0004] In addition, there are also products that can be used as rail lamps by mounting a light bulb on an adapter having movable connect means. However, since the screwing between the connect means and the light bulb may become unstable, there are problems such as low structural strength or easy occurrence of poor contact.

Mode for Carrying Out the Invention

[0010] The following will describe each embodiment of the present invention in detail with reference to the drawings. However, it should be understood that for components that play equivalent roles in different embodiments, even if their structures do not exactly match, they may be given the same reference numerals. Also, in the following description, terms such as "upper" and "lower" are used based on the drawings, but these are used for convenience of explanation and do not limit the implementation method or the scope of rights of the present invention.

[0011] The rail lamp 200 of the first embodiment of the present invention is shown in FIGS. 2 to 4. As shown in the drawings, this rail lamp 200 can be detachably attached to the rail 9. This rail 9 has a pair of first conductive members 911 that extend along a predetermined rail extension direction X and are spaced apart from each other across a rail groove 90 having a rail opening 901 that opens downward in the drawing, and a pair of first guide portions 91 that are spaced apart from each other across the rail extension direction corresponding to the pair of first conductive members 911 and extend in parallel, a second conductive member 921 that extends along the rail extension direction X, and a second guide portion 92 corresponding to the second conductive member 921.

[0012] In the rail 9 applied in this embodiment, both of the two first guide portions 91 have a groove-shaped structure that opens toward the rail groove 90, and the two first conductive members 911 are respectively arranged in the groove-shaped structures of the corresponding first guide portions 91 so as to face the rail groove 90. Further, the second guide portion 92 also has a groove-shaped structure that opens toward the rail groove 90, and the second conductive member 921 is arranged in the groove-shaped structure of the second guide portion 92 so as to face the rail groove 90.

[0013] As shown in FIGS. 3, 5, 6, and 7, the rail lamp 200 of this first embodiment includes a lamp cover 2, connection means 3, and light emitting means 4.

[0014] The lamp cover 2 surrounds the light emitting space 20, a cover opening 21 communicating with the light emitting space 20 is formed, and the light emitting space 20 is filled with air. The cover opening 21 in this embodiment is circular, and an explosion-proof layer 22 is applied to the inner surface of the lamp cover 2. Thereby, for example, when the lamp cover 2 is a glass globe and the globe is broken when it falls to the ground or the like due to an accident, the situation where the glass material constituting the globe scatters can be avoided, so it has higher safety. Incidentally, it is also possible to form an opening communicating with the light emitting space 20 on the opposite side of the cover opening 21 for attaching to the connection means 3.

[0015] The cover opening 21 formed in the lamp cover 2 is fixed to the connection means 3 by an adhesive 5, and the adhesive 5 adopted in this embodiment has heat dissipation and electrical insulation performance. The adhesive 5 covers all or part of the cover opening 21. It is also possible to use ultrasonic bonding technology for joining the lamp cover 2 to the connection means 3 by vibration by ultrasonic waves instead of the adhesive 5.

[0016] The connection means 3 is attached to the rail 9 so as to be movable along the rail extending direction X, and is configured to have a pedestal unit 301, a control module 302, a pair of first connection terminals 303, and a second connection terminal 304.

[0017] The pedestal unit 301 has a lamp cover 2 adhesively fixed to one end by an adhesive 5, and includes a lamp holding portion 31 that surrounds the accommodation chamber 30 and a pedestal body portion 32 that extends from the lamp holding portion 31 to the side opposite to the lamp cover 2.

[0018] The lamp holding portion 31, which is located on the side opposite to the one end where the lamp cover 2 of the lamp holding portion 31 is fixed and can be electrically connected to the second conductive material 921, has a housing 311 formed in a circular tube shape and a cap 312 disposed in the housing 311.

[0019] The control module 302 is disposed in the lamp holding portion 31 and configured to be electrically connected to the light emitting means 4 so as to control the operation of the light emitting means 4. In this embodiment, the control module 302 is attached to the pedestal unit 301 and is entirely covered by the adhesive 5, but in some embodiments, it is partially covered by the adhesive 5.

[0020] The housing 311 has a housing opening 313 that communicates with the accommodation chamber 30 and opens toward the lamp cover 2 side, an annular groove 314 that opens toward the accommodation chamber 30 on the side away from the lamp cover 2 from the housing opening 313, and a narrow groove 315 that extends in a direction away from the housing opening 313 to communicate the accommodation chamber 30 with the outside. The housing 311 in this first embodiment is assembled into a circular tube shape by a member having two semi-circular cross-sections as shown in FIG. 6, and the shape and size of the housing opening 313 are configured to allow the cover opening 21 of the lamp cover 2 to enter.

[0021] The control module 302 includes a control board 33 that is fitted into the annular groove 314 of the lamp holder 31, and an adapter board 34 that is electrically connected to the control board 33. Since the control board 33 is fitted into the annular groove 314 of the lamp holder 31, it is located within the accommodation chamber 30, and includes a circuit board body 331 and an insertion member 332 attached to the circuit board body 331. The insertion member 332 has two electrical connection posts 333 that are electrically connected to the circuit board body 331. The adapter board 34 has two insertion holes 341 into which the two electrical connection posts 333 of the insertion member 332 are respectively inserted, and two connection points 342. In this first embodiment, each connection point 342 is a conductive clip. In other variations, the connection point 342 can be configured as a metal pad made of, for example, copper or silver material. Thus, the control module 302 in this embodiment is located within the lamp holder 31, but in some embodiments, it is also possible to configure the control module 302 to protrude from the lamp holder 31.

[0022] A pair of engaging members 322 that fit corresponding to a pair of first guide portions 91 of the rail 9 so that the connecting means 3 can move relative to the rail 9 along the rail extending direction, a pair of first connection terminals 303 that are located on the opposite side of the end where the lamp cover 2 of the lamp holder 31 is fixed and are both electrically connected to the control module 302, and a second connection terminal 304 that is located on the opposite side of the end where the lamp cover 2 of the lamp holder 31 is fixed and can be electrically connected to the second conductive material 921.

[0023] In this embodiment, the light emitting means 4 is arranged on the connecting means 3 so as to extend into the light emitting space 20 from the connecting means 3.

[0024] As shown in FIGS. 2 and 6, the cap 312 is movably disposed in the housing 311 along the height direction Z that is substantially orthogonal to the rail extending direction X. Unless the cap 312 receives an external force other than the external force from the spring 316, the cap 312 is pushed by the spring 316 and protrudes from the upper surface of the lamp holding portion 31. When the upper end of the cap 312 is pushed and moved so as to coincide with the upper surface of the lamp holding portion 31 by an external force, the cap 312 compresses the spring 316, and the spring 316 accumulates an elastic restoring force for pushing the cap 312 back.

[0025] As shown in FIGS. 3 to 5, the pedestal main body portion 32 extends from the lamp holding portion 31 and has a tubular member 321 whose diameter is smaller than the diameter of the lamp holding portion 31, and two engaging members 322 formed on two opposite sides of the tubular member 321 with a space therebetween. Each engaging member 322 in this embodiment is a protruding block and is used for joining to the two first guide portions 91. The pedestal main body portion 32 further has two terminal accommodating grooves 323 whose shapes are plane-symmetrical. Each terminal accommodating groove 323 has an L shape, extends upward from the lower side in the height direction Z of the tubular member 321 and protrudes from one engaging member 322, and communicates the accommodating chamber 30 and the outside. The maximum width of each engaging member 322 is slightly narrower than the width of the rail opening 901 of the rail 9. The distance from one engaging member 322 to the other engaging member 322 is longer than the width of the rail opening 901 of the rail 9.

[0026] As shown in FIGS. 3, 5, and 6, each first connection terminal 303 is mounted on the pedestal unit 301 and electrically connected to the control module 302. Each first connection terminal 303 has a base end 351 welded and fixed to the control board 33 and a tip end 352 protruding from the engagement member 322 so as to be exposed in one terminal accommodation groove 323. Each first connection terminal 303 is welded and fixed to the control board 33 by each base end 351, thereby being electrically connected to each connection point 342 of the adapter board 34. The tip end 352 of each first connection terminal 303 is electrically connected by directly contacting the corresponding first conductive material 911 of the rail 9. The second connection terminal 304 is attached to the pedestal main body 32 and is electrically connected by protruding from the tubular member 321 and directly contacting the second conductive material 921 of the rail 9. The second connection terminal 304 in this first embodiment is not electrically connected to the control module 302, but in other variations, the second connection terminal 304 can play a role of grounding by being electrically connected to the control module 302.

[0027] Furthermore, the lamp holding portion 31 is filled with an insulating heat dissipation grease 6. In some embodiments, the insulating heat dissipation grease 6 fills the space in the lamp holding portion 31 and contacts the lamp holding portion 31. Also, in some embodiments, the insulating heat dissipation grease 6 is filled in the lamp holding portion 31 so as to cover at least a part of the lower surface of the control board 33.

[0028] As shown in FIGS. 5 to 7, the light emitting means 4 is disposed on the lamp cover 2 and emits light toward the light emitting space 20 based on the control by the control module 302. The light emitting means 4 in this first embodiment is an LED filament and has two filament assemblies 41 that are electrically connected to the control module 302 and disposed in the light emitting space 20 of the lamp cover 2. Each filament assembly 41 has a plurality of filaments 411 arranged at intervals, a first connection plate 412, and a second connection plate 413. Each filament 411 has an elongated light emitting portion 414, and an anode end 415 and a cathode end 416 at both ends of the light emitting portion 414, respectively. The first connection plate 412 is connected to the anode end 415 of each filament 411 and can be specifically made of, for example, the same metal material as the anode end 415 of the filament 411. The second connection plate 413 is connected to the cathode end 416 of each filament 411 and can be specifically made of, for example, the same metal material as the cathode end 416 of the filament 411.

[0029] The first connection plate 412 of one filament assembly 41 and the second connection plate 413 of another filament assembly 41 are welded and fixed to each other. That is, these two filament assemblies 41 are connected in series. Also, the second connection plate 413 of one filament assembly 41 and the first connection plate 412 of another filament assembly 41, which are on the opposite sides of the first connection plate 412 of one filament assembly 41 and the second connection plate 413 of another filament assembly 41 that are welded and fixed to each other, are respectively inserted into each connection point 342 of the adapter substrate 34 to be electrically connected to the adapter substrate 34. Note that soldering can also be performed on each connection point 342 to strengthen the fixing of the first connection plate 412 and the second connection plate 413 to each connection point 342.

[0030] When power is supplied to each first connection terminal 303, each light emitting portion 414 of each filament assembly 41 can emit light, and a lighting effect can be exerted.

[0031] In some embodiments, the light emitting means 4 is a halogen lamp.

[0032] In some embodiments, the adapter board can be omitted by providing a configuration in which each filament assembly 41 can be directly connected to the control module 302.

[0033] In the present invention, the control module 302 is arranged in the lamp holding portion 31 of the connecting means 3, and the connecting means 3 is fixed to the lamp cover 2 to create an integrated lamp. Therefore, it can be directly attached to the rail for use without separately preparing means for connection, which is suitable for miniaturization and has the effect of improving the structural strength. Further, since the adhesive 5 used in this embodiment has heat dissipation and electrical insulation performance, the heat generated during the operation of the control module 302 and the light emitting means 4 is transmitted to the lamp holding portion 31, the lamp cover 2, and each first connection terminal 303, and can be further released to the outside from the lamp holding portion 31, the lamp cover 2, and each first connection terminal 303. Therefore, a sufficient heat dissipation effect can be ensured without injecting a specific gas for heat dissipation into the lamp cover 2.

[0034] It should be noted that the control board 33 and the adapter board 34 in the first embodiment are each independent. Therefore, during manufacturing, after the adapter board 34 is mounted on the control board 33, the control board 33 is attached to the annular groove 314 of the lamp holding portion 31, and each filament assembly 41 is fixed to the adapter board 34 by welding, so that the assembly of the light emitting means 4 and the control module 302 is completed. Therefore, the manufacturing of this first embodiment is simple and the yield can be improved.

[0035] The following describes how to attach this first embodiment to the rail 9 with reference to FIG. 8.

[0036] First, after inserting the connection means 3 into the rail groove 90 in a first posture (refer to the left side of FIG. 8) where a pair of engaging members 322 are arranged so as to substantially coincide with the rail extending direction X, the pair of engaging members 322 are turned to a second posture (refer to the right side of FIG. 8) where they are arranged so as to substantially coincide with the rail width direction Y orthogonal to the rail extending direction X, and when the pair of engaging members 322 are respectively fitted to a pair of first guide portions 91 of the rail 9, each first connection terminal 303 comes into direct contact with the first conductive material 911 and is electrically connected. Therefore, when electricity is passed through each first conductive material 911 of the rail 9, the rail lamp 200 can be made to emit light. At this time, a part of the cap 312 enters the rail groove 90 and restricts the relative rotation of the rail lamp 200 with respect to the rail 9. When removing the rail lamp 200 from the rail 9, when the cap 312 is pushed and moved until it coincides with the upper surface of the lamp holding portion 31 to release the restricting effect by the cap 312, the connection means 3 can be returned from the second posture (refer to the right side of FIG. 8) to the first posture (refer to the left side of FIG. 8), and the connection means 3 can be withdrawn from the rail groove 90.

[0037] A second embodiment of the present invention is shown in FIG. 9, and the second embodiment is different from the first embodiment in the following points.

[0038] First, the lamp cover 2 is made of a white plastic material, and the explosion prevention layer is omitted.

[0039] And in the control module 302, the adapter substrate 34 and the insertion member 332 (refer to FIG. 6) are omitted.

[0040] The light-emitting means 4 is disposed in the control module 302 and includes an LED module 42 that is welded and fixed to the control module 302, and a sleeve member 43 that is mounted outside the LED module 42. As the LED module 42, an SMD (Surface Mount Device) or COB (Chip on Board) type LED can be used. The sleeve member 43 blocks the adhesive 5 from adhering to the outside of the LED module 42. Since the lamp cover 2 is made of a white plastic material, the light emitted by the LED module 42 is diffused, and the entire light-emitting space 20 appears bright. Therefore, the light emitted by this second embodiment is relatively soft. For this reason, the rail lamp of this second embodiment can also be used for decorative purposes in addition to lighting.

[0041] FIG. 10 shows a third embodiment of the present invention, which is different from the second embodiment in the following points.

[0042] First, the lamp cover 2 is made of a transparent glass material.

[0043] And the lamp holding portion 31 is not filled with insulating heat-dissipating grease (see FIG. 9).

[0044] Also, the sleeve member 43 is a cylindrical body made of a transparent acrylic material, and a space for accommodating the LED module 42 is provided at its upper end. Therefore, the sleeve member 43 of this embodiment extends into the light-emitting space 20 and functions as a light guide.

[0045] When the LED module 42 of this embodiment emits light, the light is guided by the sleeve member 43. Therefore, when looking at the sleeve member 43 from outside the lamp cover 2, the sleeve member 43 emits light highly and can appear like an incandescent bulb.

[0046] In some modified examples, the sleeve member is omitted from the light-emitting means 4, and the lamp cover 2 can be formed as a cylindrical body made of a transparent acrylic material. In this case, only the light-emitting means is arranged in the light-emitting space and there is no space where air intervenes.

[0047] FIG. 11 shows a fourth embodiment of the present invention. This fourth embodiment is mainly for corresponding to four-wire power distribution and is different from the first embodiment in the following points.

[0048] First, since this rail lamp 200 has a configuration having two pairs of first connection terminals 303 and two pairs of engaging members 322, two pairs of first conductive materials 911 and two pairs of first guide portions 91 are correspondingly arranged on the corresponding rail 9.

[0049] In this embodiment, the lamp cover 2 is formed in a shape of a Western pear.

[0050] FIG. 12 shows a fifth embodiment of the present invention. This fifth embodiment is mainly for corresponding to two-wire power distribution and is different from the first embodiment in the following points.

[0051] First, this rail lamp 200 has a configuration having only one pair of first connection terminals 303 and one pair of engaging members 322, and one pair of first conductive materials 911 and one pair of first guide portions 91 are correspondingly arranged on the corresponding rail 9 (the configuration corresponding to the second connection terminal and the second guide portion is omitted).

[0052] Also, in this fifth embodiment, one pair of first connection terminals 303 are respectively located above one pair of engaging members 322 in the height direction Z, one pair of first connection terminals 303 are electrically connected to one pair of first conductive materials 911, and one pair of engaging members 322 are engaged with one pair of first guide portions 91.

[0053] In this embodiment, the lamp cover 2 is a lamp cover in the shape of a sky lantern.

[0054] As can be seen from the above embodiments, even if the type of the rail 9 is different, the rail lamp 200 of the present invention can be similarly applied by correspondingly changing the number and positions of the first connection terminal 303 and the second connection terminal 304.

[0055] In the rail lamp 200 of the present invention, the control module 302 is arranged in the lamp holding part 31 of the connection means 3, and the connection means 3 is fixed to the lamp cover 2 to form an integral lamp. Therefore, it can be directly attached to the rail for use without separately preparing means for connection, which is suitable for miniaturization and has the effect of improving the structural strength. Further, when the connection means 3 and the lamp cover 2 are fixed with the adhesive 5, the control module 302 and the light emitting means 4 can dissipate heat through the adhesive 5. Furthermore, as the lamp cover 2, various shapes and transparencies including the above example can be used, so it can be adapted to various situations.

[0056] The embodiments of the present invention have been described above, but the present invention is not limited thereto, and various changes can be made without departing from the gist thereof.
