Description

Technical Field

[0001] The utility model relates to a lighting device, in particular to a detachable lamp head and a lamp tube. Background Art

[0002] A lamp tube generally includes a tube body and lamp heads connected to both ends of the tube body. During production and assembly, electrical components such as a power driving board are installed in the lamp head, and the lamp head is fixedly adhered to the end of the tube body by bonding. When maintenance or replacement of the electrical components in the tube body or the lamp head is required, it is difficult to separate the lamp head from the tube body. If forced separation is carried out, irreversible damage is usually caused to both of them. Therefore, there is an urgent need for a lamp head that can be disassembled and assembled on the tube body. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a detachable lamp head and a lamp tube to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] A detachable lamp head includes: a connecting sleeve with at least two first conductive members arranged inside; a plugging seat with a driving board arranged inside. At positions of the plugging seat facing at least two of the first conductive members, clamping holes are respectively arranged. At least two second conductive members are connected to the driving board. At least two of the first conductive members are respectively clamped in the facing clamping holes, and at least two of the first conductive members are respectively electrically connected to at least two of the second conductive members.

[0006] This technical solution has at least the following beneficial effects: A driving board for controlling and driving an external light source is arranged inside the plugging seat, and at least two second power connection members for connecting electricity are connected to the driving board. The connecting sleeve and the plugging seat can be disassembled and assembled with each other. Specifically, the first conductive members inside the connecting sleeve are aligned with the clamping holes on one side of the plugging seat. The connecting sleeve and the plugging seat are moved closer to each other, so that the first conductive members are clamped in the clamping holes. After the first conductive members are installed in place, the first conductive members are also electrically connected to the second conductive members. During use, the connecting sleeve can be connected to the tube body of an external lamp tube to power on the light source inside the tube body. In this way, the cooperation between the first conductive members and the clamping holes can realize the structural connection between the connecting sleeve and the plugging seat and conduct electricity. When maintenance of the light source inside the tube body and electrical components such as the driving board inside the plugging seat is required, the connecting sleeve and the plugging seat can be disassembled and assembled, improving the convenience of replacement and maintenance and reducing the use cost.

[0007] As a further improvement of the above technical solution, a partition is connected inside the connecting sleeve, and the two first conductive members are respectively connected to the partition. The partition forms a structure for connecting and supporting the first conductive members inside the connecting sleeve, and can axially separate the inside of the connecting sleeve along the axis of the connecting sleeve, so that one end of the connecting sleeve is used to connect to the plugging seat, and the other end is used to connect to an external pipe body. In addition, there are two first conductive members, which can be used as the conductive connection structures for the positive and negative electrodes respectively.

[0008] As a further improvement of the above technical solution, the first conductive member includes a connecting section and a clamping section connected perpendicular to each other. One end of the connecting section far from the clamping section is connected inside the connecting sleeve. The two clamping sections can respectively pass through the two clamping holes. When the connecting sleeve and the plugging seat are rotated relatively, the two clamping sections can respectively clamp the inner side wall of the plugging seat, and the two clamping sections are respectively electrically connected to the two second conductive members. In the first conductive member, the connecting section can make the clamping section far from the partition, so that when the connecting sleeve abuts against the plugging seat, the clamping section can pass through the clamping hole. When it is necessary to relatively clamp the clamping section inside the plugging seat, the connecting sleeve and the plugging seat are rotated relatively. At this time, the clamping section and the clamping hole are misaligned with each other, and the clamping section can be clamped to the inner side wall of the plugging seat. In this way, the connecting sleeve and the plugging seat can be assembled and connected to each other. When it is necessary to disassemble the two, the connecting sleeve and the plugging seat are rotated relatively in the reverse direction, so that the clamping section is aligned with the clamping hole, and the connecting sleeve and the plugging seat can be separated from each other, which is convenient for disassembly and assembly.

[0009] As a further improvement of the above technical solution, an elastic member is connected to the center of the partition. One end of the elastic member far from the partition abuts against the outer side surface of the plugging seat, and the elastic member generates elastic deformation along the axis direction of the connecting sleeve. When the connecting sleeve and the plugging seat are connected to each other, the end of the elastic member presses against the outer side surface of the plugging seat, and the elastic member will be elastically compressed along the axis of the connecting sleeve. After the clamping section is clamped to the inner side wall of the plugging seat, the elastic force of the elastic member is used to make the connecting sleeve and the plugging seat tend to separate from each other. At this time, the clamping section can be further pressed against the inner side wall of the plugging seat, so as to further improve the structural stability of the clamping of the first conductive member.

[0010] As a further improvement of the above technical solution, an avoidance hole is arranged at a position on the outer side of the plugging seat opposite to the elastic member. The driving plate is connected with a third conductive member, and the third conductive member extends out of the avoidance hole. The elastic member is a spring, and the elastic member abuts against the third conductive member. The electrical components in the external pipe body can be electrically connected to the end position of the spring connected to the partition, and the other end of the spring can press against the third conductive member, so as to generate elastic deformation. In this way, an electrical connection can be formed between the spring and the third conductive member, and the spring presses tightly against the third conductive member to form a stable electrical connection.

[0011] As a further improvement of the above technical solution, the third conductive member includes a power connection piece and a power connection post that are connected to each other. The power connection piece is located outside the plugging seat, the power connection piece covers the avoidance hole, the power connection post is connected to the driving plate, and the elastic member abuts against the power connection piece. The power connection piece is located outside the plugging seat, and the plugging seat itself provides support for it, so that the power connection piece stably presses the spring, while the power connection post extends from the power connection piece, passes through the avoidance hole on the plugging seat and is connected to the driving plate, thereby realizing electrical connection with the driving plate.

[0012] As a further improvement of the above technical solution, the connection line between the two clamping sections deviates from the axis of the connecting sleeve. Correspondingly, the clamping holes on the outside of the plugging seat are directly opposite to the two first conductive members. When connecting the connecting sleeve and the plugging seat, it is necessary to align the two first conductive members with the two clamping holes, which is beneficial to avoid the problem of reverse connection of positive and negative electrodes and achieve accurate electrical connection.

[0013] As a further improvement of the above technical solution, an anti-fooling block is connected to the outside of the end of the plugging seat close to the connecting sleeve, and a clamping groove is provided on the outside of the end of the connecting sleeve close to the plugging seat. The anti-fooling block is cooperatively connected to the clamping groove. Starting from the connection structure of the plugging seat and the connecting sleeve, when the two are connected to each other, the anti-fooling block is directly opposite to the clamping groove, so that the plugging seat and the connecting sleeve can be smoothly matched. At this time, the anti-fooling block is cooperatively connected to the clamping groove, so that the problem of reverse connection of positive and negative electrodes can also be avoided, and accurate electrical connection can be achieved.

[0014] As a further improvement of the above technical solution, a convex platform is provided on the side of the plugging seat facing the connecting sleeve, and the connecting sleeve can be sleeved outside the convex platform. After the connecting sleeve and the plugging seat are connected to each other, the convex platform abuts against the inner side wall of the connecting sleeve, which can limit the relative offset between the connecting sleeve and the plugging seat, so as to further improve the stability of the connection between the two and improve the sealing effect on the inside.

[0015] A lamp tube includes a tube body and the above detachable lamp head, and one end of the connecting sleeve away from the plugging seat is connected to the end of the tube body.

[0016] This technical solution has at least the following beneficial effects: Since a detachable lamp head is installed on the tube body, when it is necessary to maintain electrical components such as the light source in the tube body or the driving plate in the plugging seat, the connecting sleeve and the plugging seat can be disassembled from each other and replaced separately. In this way, the cooperation between the first conductive member and the clamping hole can realize the structural connection between the connecting sleeve and the plugging seat and conduct electricity, improving the convenience of replacement and maintenance and reducing the use cost.

[0026] Referring to Figure 1 、 Figure 2 and Figure 3 , a detachable lamp cap includes a connecting sleeve 100 and a plugging seat 200. There are at least two first conductive members 110 arranged inside the connecting sleeve 100. For example, the number of the first conductive members 110 can be two, three, four, etc.; a driving board is arranged inside the plugging seat 200. Naturally, a certain space is formed inside the plugging seat 200 itself, and electrical components other than the driving board can also be installed. A clamping hole 210 is arranged at the position of the plugging seat 200 opposite to the first conductive member 110. When the number of the first conductive members 110 is two, three, or four, the number of the clamping holes 210 correspondingly is two, three, or four. A second conductive member is connected to the driving board. Similarly, when the number of the first conductive members 110 is two, three, or four, the number of the second conductive members correspondingly is two, three, or four. When the first conductive member 110 is clamped in the opposite clamping hole 210, the first conductive member 110 is electrically connected to the second conductive member respectively.

[0027] As can be seen from the above, a driving board for controlling and driving an external light source is arranged inside the plugging seat 200, and at least two second power connection members for connecting electricity are connected to the driving board. The connecting sleeve 100 and the plugging seat 200 can be disassembled and assembled with each other. Specifically, the first conductive member 110 inside the connecting sleeve 100 is aligned with the clamping hole 210 on one side of the plugging seat 200. The connecting sleeve 100 and the plugging seat 200 are brought closer to each other, so that the first conductive member 110 is clamped in the clamping hole 210. After the first conductive member 110 is installed in place, the first conductive member 110 is also electrically connected to the second conductive member. During use, the connecting sleeve 100 can be connected to the tube body of an external lamp tube to energize the light source inside the tube. In this way, the structural connection between the connecting sleeve 100 and the plugging seat 200 can be realized by the cooperation of the first conductive member 110 and the clamping hole 210, and power can be supplied. When maintenance needs to be performed on the light source inside the tube or electrical components such as the driving board inside the plugging seat 200, the connecting sleeve 100 and the plugging seat 200 can be disassembled and assembled, improving the convenience of replacement and maintenance and reducing the use cost.

[0028] The first conductive member 110 can be directly connected to the inner sidewall of the connecting sleeve 100, so as to be relatively fixed within the connecting sleeve 100. Or, there are protruding rib positions formed on the inner sidewall of the connecting sleeve 100, and the first conductive member 110 is connected to the protruding rib positions. In this embodiment, a partition 120 is connected within the connecting sleeve 100, and the two first conductive members 110 are respectively connected to the partition 120. The partition 120 forms a structure for connecting and supporting the first conductive member 110 within the connecting sleeve 100, and can axially divide the interior of the connecting sleeve 100 along the axis of the connecting sleeve 100, such that one end of the connecting sleeve 100 is used to connect to the plugging seat 200, and the other end is used to connect to an external pipe body. Additionally, the number of the first conductive members 110 is two, which can respectively serve as the conductive connection structures for the positive and negative electrodes.

[0029] There are various structural forms for the first conductive member 110 to be clamped in the clamping hole 210. For example, the plugging seat 200 forms a structure for clamping the first conductive member 110 at the clamping hole 210. When the first conductive member 110 is inserted into the clamping hole 210, it can be clamped at the clamping hole 210. At this time, the second conductive member located within the plugging seat 200 realizes electrical connection by relatively pressing against the first conductive member 110 along the axis of the connecting sleeve 100. In order to more stably form an electrical connection between the first conductive member 110 and the second conductive member during clamping, in this embodiment, the first conductive member 110 includes a connecting section 111 and a clamping section 112 that are perpendicularly connected to each other. One end of the connecting section 111 away from the clamping section 112 is connected within the connecting sleeve 100, and the two clamping sections 112 can respectively pass through the two clamping holes 210. When the connecting sleeve 100 and the plugging seat 200 are relatively rotated, the two clamping sections 112 can respectively clamp the inner sidewall of the plugging seat 200, and the two clamping sections 112 are respectively electrically connected to the two second conductive members. In the first conductive member 110, the connecting section 111 can keep the clamping section 112 away from the partition 120, such that when the connecting sleeve 100 abuts against the plugging seat 200, the clamping section 112 can pass through the clamping hole 210. When it is necessary to relatively clamp the clamping section 112 within the plugging seat 200, the connecting sleeve 100 and the plugging seat 200 are relatively rotated. At this time, the clamping section 112 and the clamping hole 210 are misaligned with each other, and the clamping section 112 can clamp the inner sidewall of the plugging seat 200. In this way, the connecting sleeve 100 and the plugging seat 200 can be assembled and connected to each other. When it is necessary to disassemble the two, the connecting sleeve 100 and the plugging seat 200 are relatively reversed, such that the clamping section is aligned with the clamping hole 210, and the connecting sleeve 100 and the plugging seat 200 can be separated from each other, which is convenient for disassembly and assembly.

[0030] In the above embodiments, when the clamping section 112 is clamped to the inner side wall of the plugging seat 200, it can rely on the friction between the two to maintain the position where the clamping section 112 is clamped. In this embodiment, an elastic member 130 is connected to the center of the partition 120. One end of the elastic member 130 away from the partition 120 abuts against the outer side surface of the plugging seat 200. The elastic member 130 generates elastic deformation along the axial direction of the connecting sleeve 100. There are various structures that the elastic member 130 can adopt, such as elastic rubber, spring, elastic metal sheet, etc. When connecting the connecting sleeve 100 and the plugging seat 200, the end of the elastic member 130 presses against the outer side surface of the plugging seat 200, and the elastic member 130 will be elastically compressed along the axial direction of the connecting sleeve 100. After the clamping section 112 is clamped to the inner side wall of the plugging seat 200, the elastic force of the elastic member 130 makes the connecting sleeve 100 and the plugging seat 200 tend to separate from each other. At this time, the clamping section 112 can be further pressed against the inner side wall of the plugging seat 200, so as to further improve the structural stability of the clamping of the first conductive member 110.

[0031] In the above embodiments, the connection and power-on are mainly achieved by the abutment of the first conductive member 110 and the second conductive member. In this embodiment, the elastic member 130 can also be used to achieve connection and power-on. Specifically, an avoidance hole is provided at a position on the outer side of the plugging seat 200 opposite to the elastic member 130. The driving plate is connected with a third conductive member 220. The third conductive member 220 extends out of the avoidance hole. The elastic member 130 is a spring. The elastic member 130 abuts against the third conductive member 220. The electrical components in the external pipe body can be electrically connected to the end position of the spring connected to the partition 120, and the other end of the spring can press against the third conductive member 220, so as to generate elastic deformation. In this way, an electrical connection can be formed between the spring and the third conductive member 220, and the spring presses tightly against the third conductive member 220 to form a stable electrical connection.

[0032] When the elastic member 130 presses against the third conductive member 220, it will exert pressure on the third conductive member 220. Since the third conductive member 220 is connected to the driving board, it can be installed and fixed in the plugging seat 200 only relying on the driving board, so as to achieve relative positioning on the plugging seat 200. For the mutual abutment between the elastic member 130 and the third conductive member 220, it can be that the third conductive member 220 directly abuts against the elastic member 130 after passing through the avoidance hole, or the end of the elastic member 130 abuts against the third conductive member 220 after passing through the avoidance hole. The implementable structural forms are not limited. In order to improve the structural stability of the third conductive member 220 when subjected to the pressure of the elastic member 130, in this embodiment, the third conductive member 220 includes a power receiving sheet and a power receiving column connected to each other. In practical applications, the power receiving sheet and the power receiving column are integrally formed structures. The power receiving sheet is located outside the plugging seat 200, and the power receiving sheet covers the avoidance hole. The power receiving column is connected to the driving board, and the elastic member 130 abuts against the power receiving sheet. The power receiving sheet can be designed with a larger area to facilitate contact with the end of the elastic member 130. The power receiving sheet is located outside the plugging seat 200, and the plugging seat 200 itself provides support for it, so that the power receiving sheet stably presses on the spring. The power receiving column extends from the power receiving sheet, passes through the avoidance hole on the plugging seat 200 and is connected to the driving board, so as to achieve electrical connection with the driving board.

[0033] There are various installation methods of the two first conductive members 110 on the partition 120. For example, the two first conductive members 110 are symmetrically arranged around the axis center of the connecting sleeve 100 on the partition 120. In actual operation, the pairing relationship between the two first conductive members 110 and the two clamping holes 210 can be reversed. As an embodiment one to prevent electrical reverse connection to reduce the occurrence of electrical connection errors, the connection line between the two clamping segments 112 deviates from the axis of the connecting sleeve 100. Correspondingly, the clamping holes 210 on the outside of the plugging seat 200 are directly opposite to the two first conductive members 110. When connecting the connecting sleeve 100 and the plugging seat 200, it is necessary to align the two first conductive members 110 with the two clamping holes 210, which is beneficial to avoid the problem of positive and negative pole reverse connection and achieve accurate electrical connection.

[0034] As the second embodiment for preventing reverse electrical connection, an anti-fooling block 240 is connected to the outer side of the end of the plugging seat 200 close to the connecting sleeve 100. A card slot 140 is provided on the outer side of the end of the connecting sleeve 100 close to the plugging seat 200. The anti-fooling block 240 is fitted and connected in the card slot 140. Starting from the connection structure between the plugging seat 200 and the connecting sleeve 100, when the two are connected to each other, the anti-fooling block 240 and the card slot 140 are aligned with each other, so that the plugging seat 200 and the connecting sleeve 100 can be smoothly fitted. At this time, the anti-fooling block 240 is fitted and connected in the card slot 140. In this way, the problem of reverse connection of the positive and negative electrodes can also be avoided, and accurate electrical connection can be achieved. In practical applications, either the first embodiment or the second embodiment for preventing reverse electrical connection can be selected, or both can be used at the same time.

[0035] In order to better improve the structural stability of the connection between the connecting sleeve 100 and the plugging seat 200, in this embodiment, a boss 230 is provided on the side of the plugging seat 200 facing the connecting sleeve 100. The connecting sleeve 100 can be sleeved on the outer side of the boss 230. After the connecting sleeve 100 and the plugging seat 200 are connected to each other, the boss 230 abuts against the inner side wall of the connecting sleeve 100, which can limit the relative offset between the connecting sleeve 100 and the plugging seat 200. In this way, the stability of the connection between the two can be further improved, and the sealing effect on the inside can be improved.

[0036] The driving plate can be fixed in the plugging seat 200 by screws. In order to facilitate the installation of the driving plate, in this embodiment, the driving plate is snap-fitted in the plugging seat 200. The driving plate can be stably installed in the plugging seat 200, so as to keep the second conductive member connected to the first conductive member 110. In practical applications, holes can be provided on the driving plate, and elastic buckles are connected in the plugging seat 200, and ribs for limiting the driving plate are provided on the inner side of the plugging seat 200. When the driving plate is installed in the plugging seat 200, the ribs can quickly install the driving plate in place, and the buckles are used in cooperation with the holes on the driving plate to realize the quick positioning of the driving plate.

[0037] In order to connect the connecting sleeve 100 to the tube body of the peripheral lamp tube, the end of the connecting sleeve 100 away from the plugging seat 200 can be designed with a smaller outer diameter, so that the connecting sleeve 100 can be conveniently connected and positioned. Or a limiting rib is provided on the inner side wall of the end of the connecting sleeve 100 away from the plugging seat 200. The limiting rib extends along the axial direction of the plugging seat 200, and a plurality of them are arranged in a circumferential array around the center of the plugging seat 200, so as to be conveniently fastened to the peripheral tube body.

[0038] A lamp tube includes a tube body and the above-mentioned detachable lamp head. One end of the connecting sleeve 100 away from the plugging seat 200 is connected to the end of the tube body.

[0039] In this lamp tube, since a detachable lamp cap is installed on the tube body, when it is necessary to maintain the light source in the tube body or electrical components such as the driving board in the plugging seat 200, the connecting sleeve 100 and the plugging seat 200 can be disassembled from each other and replaced separately. In this way, the structural connection between the connecting sleeve 100 and the plugging seat 200 can be realized by the cooperation of the first conductive member 110 and the clamping hole 210, and power can be supplied, improving the convenience of replacement and maintenance and reducing the use cost.
