For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0022] The embodiment of the present application discloses a track light that is convenient for replacing optical devices.

[0023] Please refer to Figure 1 In one embodiment of the present application, a track light for facilitating replacement of an optical module 2 comprises an optical module 2, a lamp tube 1 and a mounting base 3. The lamp tube 1 is cylindrical and is mounted on a track through the mounting base 3. The optical components and lens assembly are integrated in the optical module 2. The optical module 2 provides a lighting source and is detachably mounted in the lamp tube 1. The optical module 2 and the lamp body are modularized, which can simplify the internal structure of the track light and facilitate replacement of the optical module 2.

[0024] Please refer to Figures 2 to 5, the optical module 2 is provided with a magnetic slider 13, and the lamp tube 1 is provided with a spiral slide rail 4 and a magnetic seat 5. The optical module 2 is detachably connected to the lamp tube 1 via the spiral slider under the magnetic attraction between the magnetic seat 5 and the magnetic slider 13. When the optical module 2 needs to be replaced, the optical module 2 is rotated to disconnect the connection between the magnetic slider and the magnetic seat 5. The magnetic slider 13 slides on the spiral slide rail 4 by external force, so that the optical module 2 is screwed out and protrudes outside the lamp tube 1. When the optical module 2 is replaced, the operator only needs to reinsert the optical module 2 into the spiral slide rail 4, and the optical module 2 can automatically slide in and reconnect with the lamp tube 1 under the attraction between the magnetic terminal 15 and the magnetic seat 5. The whole disassembly and assembly process is simple and can be completed by ordinary people with general common sense. There is no need to spend extra money to invite professionals to come, which reduces the maintenance cost; and the replacement process is very fast, which greatly reduces the time required to replace the optical module 2 and greatly reduces the dangers of the operator. In the disclosure of the present application, the spiral rail 4 is arranged at the lower part of the lamp tube 1, that is, the optical module 2 is installed at the lower part of the lamp tube 1, so that the installation height of the irradiation light source is reduced, so that the illumination intensity of the irradiated space is increased. At the same time, compared with the optical module 2 being installed at the upper part of the lamp tube 1, the optical module 2 is installed at the lower part of the lamp tube 1, which is more convenient for maintenance personnel to replace it.

[0025] Specifically, the optical module 2 may include an optical component 11 and a module bracket 12, the module bracket 12 is cylindrical and matches the lamp tube 1, and the magnetic slider 13 is arranged at the lower part of the module bracket 12 and extends out of the module bracket 12. The shape of the magnetic slider 13 matches the spiral slide 4. As shown in the figure, a cavity 14 is provided on one side of the magnetic slider 13 facing the spiral slide 4, and a magnetic terminal 15 is arranged in the cavity 14. The spiral slide 4 is arranged on the inner wall of the lamp tube 1, including a first side arranged along the axial direction of the lamp tube 1, a guide surface arranged along the circumferential direction of the lamp tube 1, and a second side arranged along the axial direction of the lamp tube 1, and the ports of the first side and the second side are flush with the opening of the lamp tube 1, the guide surface spirally advances toward the center point of the lamp tube 1, and the magnetic seat 5 is arranged close to the second side. The magnetic slider 13 is inserted into and close to the first side, and slides on the guide surface through the magnetic attraction between the magnetic terminal 15 and the magnetic seat 5 and finally abuts against the second side. Furthermore, the length of the second side surface matches the height of the optical module 2, and when the magnetic slider 13 slides into the bottom of the spiral slide rail 4, the optical module 2 is completely placed in the lamp tube 1. The first side surface guides the magnetic slider 13 for insertion, ensuring that a portion of the magnetic slider 13 can be inserted into the spiral slide rail 4 first, thereby preventing the magnetic slider 13 from falling from the spiral slide rail 4 due to unstable placement at the beginning. Furthermore, the length of the first side surface is not less than half of the length of the magnetic slider 13.

[0026] Optionally, in order to achieve rapid disassembly between the optical module 2 and the lamp tube 1, the attraction between the magnetic terminal 15 and the magnetic seat 5 should not be too strong, so the magnetic terminal 15 can be a magnetic buckle, which can be composed of galvanized iron plate, copper plate, magnet, etc. Further, the magnetic seat 5 can be a magnetic buckle corresponding to the magnetic terminal 15, and the opposite magnetic poles of the two magnetic buckles are arranged oppositely; or, the magnetic seat 5 can also be directly made of metal materials, such as iron, iron alloy, etc.

[0027] Optionally, the magnetic slider 13 does not exceed the projection area of ​​the module bracket 12, and the outer end surface of the optical module 2 can close the lamp tube 1. When the optical module 2 and the lamp tube 1 are connected, a closed space is formed between the two, which can isolate the electronic components in the lamp tube 1 from dust and moisture in the outside air, preventing moisture from damaging the internal electronic components and dust from interfering with the normal operation of the internal electronic components. Further, the module bracket 12 can be integrally formed.

[0028] In an optional embodiment of the present application, the cavity 14 on the magnetic slider 13 includes at least one limiting edge 17, and the limiting edge 17 is provided with an extension portion 10 parallel to the inner end surface of the cavity 14. When the magnetic terminal 15 is accommodated in the cavity 14, the extension portion 10 of the limiting edge 17 is engaged with the magnetic terminal 15, which can prevent the magnetic terminal 15 from falling off, thereby affecting the connection between the optical module 2 and the lamp tube 1. Further, the limiting edge 17 can be an elastic component. When the magnetic terminal 15 fails or is damaged, it can be replaced by breaking the limiting edge 17. Further, the side wall of the cavity 14 is not completely closed, and a gap is left between the limiting edge 17 and the side wall of the cavity 14, so that the magnetic terminal 15 can be taken out of the cavity 14 more labor-saving. Further, in order to enhance the stability of the magnetic terminal 15 in the cavity 14, the number of limiting edges 17 can be set to multiple. In another optional embodiment, the magnetic slider 13 can be an elastic member as a whole, and the magnetic terminal 15 is wrapped in the cavity 14 of the magnetic slider 13. When the magnetic terminal 15 needs to be replaced, it is squeezed out of the cavity 14, and then the new magnetic terminal 15 is squeezed back into the cavity 14.

[0029] In an optional embodiment of the present application, Figure 2-4As shown, the magnetic slider 13 is provided with a slot 16 on one side in the thickness direction thereof and the opening faces the magnetic seat 5. The magnetic seat 5 is a sheet structure and magnetic material is distributed on at least one section thereof. As shown in the figure, the magnetic seat 5 is close to the bottom of the spiral slide rail 4 and is fixed in the lamp tube 1 by bolts (not shown in the figure). When the magnetic slider 13 slides into the bottom of the spiral slide rail 4, the magnetic seat 5 is snapped into the slot 16 and magnetically connected to the magnetic terminal 15, so that the optical module 2 can be detachably installed in the lamp tube 1. Furthermore, the bottom of the slot 16 is connected with the cavity 14, so that the solid matter between the magnetic terminal 15 and the magnetic seat 5 is reduced, and the attraction between the magnetic terminal 15 and the magnetic seat 5 is increased, thereby further strengthening the connection between the optical module 2 and the lamp tube 1, preventing the optical module 2 from being separated from the lamp tube 1, and avoiding the normal use of the track light and the danger of falling from a high altitude and causing injuries to people.

[0030] Specifically, the magnetic seat 5 includes an elongated base 8, and one end of the base 8 is provided with an attachment portion 9 arranged along the thickness direction of the base 8, and the attachment portion 9 is a magnetic member or a magnetic material is dispersed in the attachment portion 9. By setting the attachment portion 9, the magnetic area between the magnetic seat 5 and the magnetic terminal 15 is increased, thereby further increasing the attraction between the two. When the magnetic slider 13 slides into the bottom of the spiral slide rail 4, the largest surface of the attachment portion 9 is close to the magnetic terminal 15 and is magnetically connected with the magnetic terminal 15, so that the optical module 2 is detachably connected to the lamp tube 1; the upper end surface of the base 8 is abutted against the inner wall of the card slot 16, so that the optical module 2 is clamped in the lamp tube 1 on the basis of the magnetic connection, preventing the optical module 2 from falling off, and further strengthening the stability of the optical module 2 installed in the lamp tube 1. Optionally, the other end of the base 8 can be provided with an extension portion 10 arranged along the thickness direction of the base 8, and the extension portion 10 is opposite to the attachment portion 9. The setting of the extension portion 10 can balance the structure of the magnetic seat 5 and improve the stability of the magnetic seat 5. Furthermore, a positioning plate 7 is provided in the lamp tube 1, and the largest surface of the extension portion 10 is close to the positioning plate 7 to prevent the magnetic seat 5 from being deflected due to the loosening of the bolt. Optionally, the magnetic seat 5 can be an integrally formed metal sheet, such as an iron sheet. Optionally, in order to strengthen the attraction between the magnetic terminal 15 and the magnetic seat 5, the magnetic seat 5 is arranged close to the inner wall of the lamp tube 1. The magnetic seat 5 can be selected as follows: Figure 2-5 The cross-sectional shape shown fits the inner wall of the lamp tube 1.

[0031] Optionally, in order to improve the reliability of the connection, the number of magnetic sliders 13 can be multiple, and the multiple magnetic sliders 13 are evenly spaced on the module bracket 12. Since the spiral slide rail 4 and the magnetic seat 5 are arranged corresponding to the magnetic terminal 15, the number of the spiral slide rail 4 and the magnetic seat 5 corresponds to the number of magnetic sliders 13, and they are also evenly spaced in the lamp tube 1. In this way, the optical component 11 can be evenly stressed in all directions after being installed in the lamp tube 1, thereby increasing the firmness. Figure 1-4 In one embodiment shown, the number of magnetic sliders 13 can be three, and they are evenly arranged on the circumference of the module bracket 12. The connection line of the three magnetic sliders 13 forms a triangle, and the triangle is the most stable figure, which can effectively balance and disperse external forces, so that the track light can have better firmness.

[0032] Optionally, a contact point 18 may be provided at the bottom of the magnetic slider 13 (see Figure 4 ), the contact point 18 is a semi-cylinder, and its width is the same as the width of the spiral slide rail 4. When the magnetic slider 13 is inserted into the spiral slide rail 4, the contact point 18 slides on the guide surface of the spiral slide rail 4.

[0033] Optionally, reinforcing ribs may be provided on the magnetic slider 13 to enhance the structural strength of the magnetic slider 13 , thereby preventing the magnetic slider 13 from deforming during use and ensuring the connection between the optical module 2 and the lamp tube 1 .

[0034] In an optional embodiment of the present application, the module bracket 12 can be detachably connected to the optical component 11 .

[0035] Optionally, the connection between the optical component 11 and the module bracket 12 can be a snap connection. The module bracket 12 can be provided with a snap head, and the optical component 11 can be provided with a snap groove, or the optical component 11 can be provided with a snap head, and the module bracket 12 can be provided with a snap groove. Specifically, the snap head is a cantilever, annular, spherical or other hook shape, and the snap groove is provided corresponding to the snap shape. It can be understood that the specific snap shape is not limited, and those skilled in the art can open the snap as appropriate. When it is necessary to replace the component, the operator needs to first rotate the optical module 2 to overcome the magnetic force and remove it from the lamp tube 1. When it is moved to a safe place, the operator needs to pull the snap head of the module bracket 12 out of the corresponding snap groove to complete the disassembly operation of the optical component 11. Then, the operator needs to select a good optical component 11 and insert the snap head into the corresponding snap groove to complete the reassembly of the optical module 2. Finally, the operator needs to reinsert the optical module 2 into the spiral slide rail 4. Through the magnetic attraction between the magnetic slider 13 and the magnetic seat 5, the optical module 2 can be quickly installed in the lamp tube 1.

[0036] Optionally, the connection between the optical component 11 and the module bracket 12 can be a threaded connection. The optical component 11 can be provided with an internal thread, and the module bracket 12 can be provided with an external thread, or the module bracket 12 can be provided with an internal thread, and the optical component 11 can be provided with an external thread. The internal thread and the external thread cooperate with each other to achieve detachability between the optical component 11 and the module bracket 12. According to actual needs, different optical components 11 can be selected to reassemble the optical module 2.

[0037] Optionally, the connection between the optical component 11 and the module bracket 12 can be a magnetic connection. The optical component 11 and the module bracket 12 can each be provided with a magnetic member, and the two magnetic members are respectively arranged at the positions where the optical component 11 and the module bracket 12 contact each other, and the opposite magnetic poles are arranged relative to each other. Alternatively, one of the optical component 11 and the module bracket 12 is provided with an iron member, and the other is provided with a magnetic member at a relative position connected to the iron member. When the optical component 11 and the module are close to each other, the lamp will be quickly assembled through the magnetic attraction; overcoming the magnetic force can enable the optical component 11 and the module bracket 12 to be quickly disassembled.

[0038] It should be noted that the optical component 11 and the module bracket 12 may also be detachably connected by using other existing public technologies, which will not be described in detail in this application.

[0039] In an optional embodiment of the present application, the lamp tube 1 is rotatably connected to the mounting base 3, so that the illumination range of the track light is increased and its practicality is increased. The specific structural method can adopt the common structural method in the field, and the present application does not limit its specifications and the functional embodiments adopted.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
