Track light

Abstract

The present disclosure provides a track lamp, belonging to the technical field of electrical appliances. The track lamp comprises a supporting assembly, a first shell and a light-emitting assembly, wherein the supporting assembly is connected with a guide rail strip. The first shell is located below the supporting assembly, and the first shell is slidingly connected with the supporting assembly along the height direction. The light-emitting assembly is located inside the first shell. Thus, the track lamp can be telescoped along the height direction, and the height of the track lamp can be adjusted. When the track lamp is installed in a guide rail strip with a large height, the first shell can be pulled downward, thereby increasing the height of the track lamp. When the track lamp is installed in a guide rail strip with a small height, the first shell can be pushed upward, thereby reducing the height of the track lamp. In this way, when the track lamp is installed in guide rail strips with different heights, the bottom of the track lamp can be flush with the bottom of the guide rail strip, thereby improving the use range of the track lamp.

Description

Technical Field

[0001] This disclosure relates to the field of electrical technology, and in particular to a track light. Background Technology

[0002] With the diversification of lighting fixtures, more and more families are starting to use track lights. When using track lights, the guide rail must first be fixed to the ceiling. The guide rail has downward-facing grooves, and the track lights are installed in these grooves. To meet market application needs, various lighting companies have launched guide rails and track lights in different specifications.

[0003] In related technologies, the height of the track light needs to match the height of the groove in the guide rail, so that the bottom of the track light is flush with the bottom of the guide rail. Therefore, track lights in these technologies can only be used with guide rails of the same specification. If the height of the track light is less than the depth of the guide rail, the side wall of the guide rail will protrude downwards relative to the track light, thus obstructing the light from the track light. If the height of the track light is greater than the depth of the guide rail, the track light will protrude from the guide rail, affecting the aesthetics of the track light and limiting its application.

Detailed Implementation

[0057] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings.

[0058] The terminology used in the embodiments of this disclosure is for illustrative purposes only and is not intended to limit the disclosure. Unless otherwise defined, the technical or scientific terms used herein should be understood in their ordinary sense by one of ordinary skill in the art to which this disclosure pertains.

The terms “upper,” “lower,” “left,” “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0059] This disclosure provides a track light, such as... Figures 1-3 As shown, the track light includes a support assembly 1, a first housing 2, and a light-emitting component 3. The support assembly 1 is connected to the guide rail. The first housing 2 is located below the support assembly 1, and the first housing 2 and the support assembly 1 are slidably connected along the height direction. The light-emitting component 3 is located inside the first housing 2.

[0060] Track lights can be either grid lights or linear lights. For example... Figure 2 As shown, the light-emitting component 3 of the grille light includes a light source component 31, an optical lens 32, and an anti-glare cup 33. (As...) Figure 3 As shown, the light-emitting component 3 of the linear light includes a light source component 31, a reflector bowl 34, and a diffuser 35. When the first housing 2 moves up and down, the light-emitting component 3 also moves accordingly.

[0061] Support component 1 can be fixed in the guide rail by snap-fit ​​or magnetic attraction, such as Figure 2 and Figure 3 As shown, the track light may also include a magnetic component 5, which is fixed to the support assembly 1. The support assembly 1 is magnetically connected to the guide rail through the magnetic component 5.

[0062] The technical solution provided in this disclosure involves a sliding connection between the support component 1 and the first housing 2 along the height direction, allowing the track light to extend and retract along the height direction, thereby adjusting the height of the track light. When the track light is installed in a guide rail with a greater height, the first housing 2 can be pulled downwards to increase the height of the track light. When the track light is installed in a guide rail with a smaller height, the first housing 2 can be pushed upwards to decrease the height of the track light. This ensures that the bottom of the track light is flush with the bottom of the guide rail when installed on guide rails of different heights, thus improving the usability of the track light.

[0063] The following is an exemplary description of how the support component 1 and the first housing 2 are slidably connected.

[0064] In some examples, such as Figures 2-5 As shown, the support assembly 1 has downwardly extending plates 122 at both ends. The first housing 2 includes a housing body 21 and two end caps 22. The two ends of the housing body 21 are respectively connected to the two end caps 22, and the end caps 22 are slidably connected to the plate 122.

[0065] In other examples, the end cap 22 may extend to the support component 1, such that the end cap 22 is slidably connected to the side wall of the support component 1.

[0066] In some examples, such as Figure 5 As shown, one of the plate 122 and the end cap 22 has a protrusion 20, and the other has a groove 10, with the protrusion 20 slidably connected to the groove 10. The sidewall of the groove 10 has a plurality of positioning grooves 10a arranged along the height direction, and the protrusion 20 can be confined in any of the positioning grooves 10a.

[0067] When the end cap 22 slides up and down, the protrusion 20 slides from one positioning groove 10a to an adjacent positioning groove 10a. When the end cap 22 is no longer under tension, the protrusion 20 can be fixed in either positioning groove 10a. At the same time, when the user pulls the end cap 22, the positioning groove 10a can provide feedback, allowing the user to perceive the number of positioning grooves 10a that the end cap 22 passes through as it slides.

[0068] The slide groove 10 has positioning grooves 10a on both side walls. The positioning grooves 10a on both sides of the slide groove 10 are arranged symmetrically and can be arc-shaped. The distance between two opposite positioning grooves 10a increases first and then decreases along the height direction. The minimum distance between two opposite positioning grooves 10a is less than the width of the protrusion 20, so that the protrusion 20 can be fixed between the two opposite positioning grooves 10a.

[0069] For example, the length of the slide 10 is 8mm-10mm, so that the overall height of the track light can be adjusted by 8mm-10mm.

[0070] In some examples, such as Figure 4 As shown, the two plates 122 are located between the two end caps 22. That is, the two end caps 22 are located on the outside of the two plates 122, so the maximum length of the track light is the distance between the two end caps 22. In this way, when the track light is installed in the guide rail, the end caps 22 can fit snugly against both ends of the guide rail, covering the gap between the guide rail and the support assembly 1, thus making the track light more aesthetically pleasing.

[0071] The slide groove 10 is located on the plate 122, and the protrusion 20 is located on the side of the end cover 22 facing the first housing 2. In this way, the end cover 22 can block the slide groove 10 and prevent foreign objects from entering the slide groove 10 and affecting the sliding of the end cover 22.

[0072] When the protrusion 20 needs to slide to the adjacent positioning groove 10a, the protrusion 20 presses against the positioning groove 10a, causing the two opposing positioning grooves 10a to deform until the minimum distance between the two opposing positioning grooves 10a is equal to the width of the protrusion 20, thereby allowing the protrusion 20 to move to the adjacent positioning groove. Therefore, the sidewall of the slide groove 10 needs to have a certain elasticity so that the positioning groove 10a can deform. For this reason, as... Figure 6 As shown, two strip grooves 1220 are provided on the plate 122. The two strip grooves 1220 are arranged along the width direction of the track light, and each strip groove 1220 extends along the height direction, with the slide 10 located between the two strip grooves 1220. In this way, the strip grooves 1220 provide space for the sidewalls of the slide 10 to deform, thereby allowing the positioning groove 10a to deform under the pressure of the protrusion 20.

[0073] Of course, in other examples, the two end caps 22 may be located inside the two plates 122, or the plates 122 may have protrusions 20 and the end caps 22 may have grooves 10. This disclosure does not specifically limit this.

[0074] In some examples, such as Figures 5-7 As shown, the plate 122 also has at least two guide grooves 1221, and the end cap 22 has at least two guide ribs 220. Each guide rib 220 extends into a guide groove 1221, and the guide rib 220 and the guide groove 1221 are slidably connected along the height direction. The guide grooves 1221 and the guide ribs 220 can limit the movement trajectory of the end cap 22 and guide the movement of the end cap 22.

[0075] For example, the plate 122 has two guide grooves 1221, and the slide 10 is located between the two guide grooves 1221.

[0076] When the user pulls the first housing 2 up and down, they can pull the housing body 21, causing the housing body 21 to move the end cap 22 up and down. Therefore, the housing body 21 and the end cap 22 need to be fixedly connected. In some examples, such as Figure 7 and Figure 8 As shown, the end cap 22 includes a cover plate 221 and a limiting plate 222, with the limiting plate 222 extending into the inner side of the housing body 21. The housing body 21 has a limiting protrusion 210 inside, and the limiting plate 222 has a limiting groove 2220. The axis of the limiting groove 2220 is along the length direction of the housing body 21, and the limiting protrusion 210 is located in the limiting groove 2220.

[0077] This allows for a fixed connection between the housing body 21 and the end cap 22, while also simplifying the assembly process between them.

[0078] Of course, in other examples, the limiting plate 222 may have a limiting protrusion, and the housing body 21 may have a limiting groove inside.

[0079] For example, such as Figure 5 and Figure 7 As shown, there is a gap between the limiting plate 222 and the cover plate 221. The limiting plate 222 has a guide rib 220 on the side facing the cover plate 221. The plate 122 of the fixing box 12 extends into the space between the limiting plate 222 and the cover plate 221.

[0080] For example, such as Figure 7 As shown, the limiting plate 222 includes a first connecting plate 2221 and a second connecting plate 2222. One end of the first connecting plate 2221 is connected to the cover plate 221, and the top of the first connecting plate 2221 is connected to the second connecting plate 2222, with a gap between the second connecting plate 2222 and the cover plate 221. The guide rib 220 and the limiting groove 2220 can both be located on the second connecting plate 2222.

[0081] In some examples, such as Figure 9 As shown, the support component 1 has a receiving groove 110. The receiving groove 110 opens downwards, and the housing body 21 extends into the receiving groove 110. Since the light-emitting component 3 is located inside the housing body 21, if the second housing 11 extends into the housing body 21, it is easy for the second housing 11 to interfere with the light-emitting component 3 when it moves up and down. In order to prevent the second housing 11 from interfering with the light-emitting component 3, grooves need to be machined on the two side walls of the housing body 21 so that the second housing 11 can extend into the grooves, but this will increase the machining difficulty of the housing body 21. Therefore, extending the housing body 21 into the receiving groove 110 can both avoid the interference between the second housing 11 and the light-emitting component 3 and reduce the machining difficulty of the housing body 21.

[0082] The housing body 21 includes a first sub-housing 211 and a second sub-housing 212 connected along the height direction. The width of the first sub-housing 211 is smaller than the width of the second sub-housing 212, and the first sub-housing 211 extends into the interior of the receiving groove 110. The width of the second sub-housing 212 is greater than or equal to the width of the support assembly 1. In this way, the outer wall of the second sub-housing 212 can fit snugly against the inner wall of the guide rail, making the gap between the track light and the inner wall of the guide rail invisible to the user, thereby improving the aesthetics of the track light.

[0083] For example, the outer wall of the second sub-shell 212 may be flush with the outer wall of the support assembly 1.

[0084] In some examples, such as Figures 1-3 As shown, the support assembly 1 includes a second housing 11 and two fixing boxes 12. Figure 5 and Figure 6 As shown, the fixing box 12 includes a box body 121 and a plate body 122 connected along the height direction. The two ends of the second housing 11 are respectively connected to the box bodies of the two fixing boxes 12. The second housing 11 is fixed to the guide rail through the box body 121.

[0085] In the manufacturing of track lights, track lights of different lengths can be produced by adjusting the length of the housing body 21 and the length of the second housing 11. The fixing box 12 and the end cap 22 can be used as standard parts and assembled into track lights of different lengths.

[0086] The mounting box 12, also known as the electrical box, is used to house electrical components to power the track lights. Alternatively, the mounting box 12 may not contain any electrical components; this embodiment does not specifically limit this.

[0087] For example, the second housing 11 and the housing body 21 can be made of aluminum alloy, and the fixing box 12 and the end cap 22 can be made of injection molded material.

[0088] like Figure 2 and Figure 3 As shown, the fixing box 12 also includes a top cover 124, which is fixed to the top of the box body 121.

[0089] In some examples, such as Figure 5 and Figure 6 As shown, the connection between the box body 121 and the plate body 122 is also provided with a reinforcing rib 123, thereby strengthening the connection between the box body 121 and the plate body 122 and making the connection between the box body 121 and the plate body 122 less prone to breakage.

[0090] For example, the support assembly 1 may not include the fixing box 12, in which case the two ends of the second housing 11 each have a plate 122. Alternatively, the support assembly 1 includes a second housing 11 and a fixing box 12, with one end of the second housing 11 connected to the box body 121 of the fixing box 12, and the other end having a downwardly extending plate. Or, the support assembly 1 includes a second housing 11 and a fixing box 12, with the two ends of the fixing box 12 each having a plate 122, and the fixing box 12 fixed to the top of the second housing 11.

[0091] In some examples, such as Figure 10 As shown, the second housing 11 includes a third sub-housing 111 and a fourth sub-housing 112 connected along the height direction. The two ends of the third sub-housing 111 are respectively connected to the housing bodies 121 of the two fixed boxes 12, and the fourth sub-housing 112 is slidably connected to the housing body 21 along the height direction. The length of the fourth sub-housing 112 is greater than the length of the third sub-housing 111, and the top end of the fourth sub-housing 112 is engaged with the housing body 121. The interiors of the third sub-housing 111 and the fixed boxes 12 are used to house electrical components.

[0092] The second housing 11 and the fixing box 12 are snapped together, which can prevent the fixing box 12 from falling off the second housing 11 and also makes the assembly method between the second housing 11 and the fixing box 12 relatively simple.

[0093] In some examples, such as Figures 10-12 As shown, the bottom of the housing 121 has a buckle 1211, and the top of the fourth sub-housing 112 has a slot 1121, with the buckle 1211 engaging with the slot 1121. One end of the buckle 1211 has a protrusion, which engages with the slot 1121. This prevents the housing 12 from detaching from the second housing 11 when subjected to lateral pulling force.

[0094] The buckle 1211 is an elastic buckle. One end of the buckle 1211 is connected to the box body 121 of the fixing box 12, and the other end and side wall of the buckle 1211 have gaps with the box body 121, so that the buckle 1211 can deform under the action of external force. When the fixing box 12 is installed on the second housing 11, the lower end of the protrusion of the buckle 1211 abuts against the top end of the fourth sub-housing 112. Under the compression of the fourth sub-housing 112, the buckle 1211 deforms, so that the buckle 1211 can move toward the third sub-housing 111 until the protrusion of the buckle 1211 extends into the slot 1121.

[0095] For example, the housing 121 has two latches 1211, and the top of the fourth sub-housing 112 may have a slot 1121. Both latches 1211 engage with the slot 1121, thereby strengthening the connection between the housing 12 and the second housing 11. Alternatively, the top of the fourth sub-housing 112 may have two slots 1121, with the two latches 1211 engaging with the two slots 1121 respectively.

[0096] In some examples, such as Figures 10-12 As shown, there is a limiting groove 120 between the box body 121 and the plate body 122. The top wall of the fourth sub-shell 112 is limited in the limiting groove 120, thereby preventing the fixed box 12 from falling off the second shell 11 when subjected to pulling force in the vertical direction (such as when the end cap 22 moves up and down).

[0097] For example, such as Figure 11 As shown, the top wall of the fourth sub-shell 112 has a locking groove 1122 at the end facing the fixing box 12. A part of the plate 122 extends into the locking groove 1122, and the bottom wall of the locking groove 1122 is engaged with the limiting groove 120.

[0098] In some examples, the track light also includes a conductive component 4. The conductive component 4 is used to transfer electricity from the power grid to the light-emitting component 3, thereby enabling the light-emitting component 3 to operate. For example... Figure 13 As shown, the support assembly 1 has a receiving groove 110, and at least a portion of the first housing 2 and at least a portion of the conductive assembly 4 are located in the receiving groove 110. The first housing 2 has a wire through-hole 23, through which the conductive assembly 4 is connected to the light-emitting assembly 3 (e.g., ...). Figure 10 (As shown by the dashed line in the diagram). When the first housing 2 moves up and down, the end of the conductive component 4 connected to the light-emitting component 3 will also move accordingly.

[0099] In this design, there is a gap between the top of the housing body 21 and the end cap 22 of the first housing 2, which can serve as a wire through-hole 23. This eliminates the need to machine additional through holes on the housing body 21, thereby reducing the number of machining steps for the housing body 21.

[0100] In some examples, such as Figure 14 and Figure 15 As shown, the support assembly 1 includes a second housing 11, which includes a third sub-housing 111 and a fourth sub-housing 112 connected along the height direction. The fourth sub-housing 112 has a receiving groove 110. The conductive assembly 4 includes a power supply assembly 41 and a terminal wire 42. The terminal wire 42 is located in the receiving groove 110, the power supply assembly 41 is located in the third sub-housing 111, and the fourth sub-housing 112 has a wire passage groove 1123. One end of the terminal wire 42 passes through the wire through opening 23 and connects to the light-emitting assembly 3, and the other end passes through the wire passage groove 1123 and connects to the power supply assembly 41. Figure 14 and Figure 15 The connection between terminal line 42 and power supply assembly 41 is not shown in the diagram.

[0101] The two ends of the second housing 11 can communicate with the housing 121 of the two fixing boxes 12, and one end of the terminal wire 42 can also pass through the gap between the two latches 1211 of the housing 121, thereby extending into the interior of the fixing box 12 and the third sub-housing 111. Alternatively, the bottom wall of the third sub-housing 111 can have a through hole, and one end of the terminal wire 42 can pass through the through hole and extend into the interior of the third sub-housing 111.

[0102] The first wire guide groove 1123 is relatively long, approximately 38mm-45mm. When the first housing 2 moves upward, the terminal wire 42 also moves upward, and the wire guide groove 1123 provides space to accommodate the terminal wire 42. The wire guide groove 1123 can communicate with the slot 1121 and the latching slot 1122, and the wire guide groove 1123 is located between the slot 1121 and the latching slot 1122.

[0103] The fourth sub-shell 112 may have only one locking groove 1122.

[0104] In some examples, such as Figure 14 and Figure 15 As shown, the power supply assembly 41 includes two conductive copper sheets 411 and a rectifier 412, which are connected by wires. The rectifier 412 is located in the third sub-housing 111 of the second housing 11, and the two conductive copper sheets 411 are located in a fixing box 12. The fixing box 12 has two through holes 12a, and the contacts 4110 of the two conductive copper sheets 411 extend from the two through holes 12a respectively, so that the contacts 4110 contact the conductive copper strip of the guide rail and are electrically connected to the guide rail. In this way, the conductive copper sheets 411 can draw power from the guide rail, and the rectifier 412 can convert the alternating current into direct current and then transmit the direct current to the light-emitting assembly 3. The rectifier 412 can be a circuit board.

[0105] In some examples, the contact 4110 of the conductive copper sheet 411 has an area of ​​15 mm². 2 -20mm 2 This results in a large contact area between contact 4110 and the guide rail. Thus, when the conductive copper strip in the guide rail is located at different positions in the height direction, contact 4110 can easily contact the conductive copper strip in the guide rail, thereby electrically connecting the conductive copper sheet 411 to the guide rail.

Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
