Description

Technical Field

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

[0002] In current microwave lamp tubes, a microwave radar sensor and a power supply system are integrated on a circuit board, and the whole is installed in a lamp cap. When connecting the lamp cap to a glass tube, it is necessary to weld the leads of the light source in the glass tube to the circuit board. However, the welding wires are prone to interfere with the microwave radar sensor during the assembly process, causing interference to the sensing signal, resulting in adverse phenomena such as product mis-triggering and too short sensing distance, ultimately making the product unable to reach the expected performance. Moreover, since the lamp cap is bonded to the glass tube with glue, when the light source in the glass tube needs to be replaced, the lamp cap and the glass tube cannot be separated from each other. Therefore, there is an urgent need for a lamp cap that can be easily disassembled, assembled, and maintained. Summary of the Utility Model

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

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

[0005] A lamp cap includes: a connection base, one end of which is a connection end, and a plurality of terminal posts extending towards the connection end are arranged inside the connection base; a power supply base, inside which a driving board is arranged, and a plurality of connection members are arranged at the end of the power supply base facing the connection end. The connection end is detachably connected to the power supply base, and the plurality of terminal posts are respectively electrically connected to the plurality of connection members.

[0006] This technical solution has at least the following beneficial effects: The connection base is used to connect to the end of the tube body of an external lamp tube. The light sources in the lamp tube are respectively wired to the plurality of terminal posts, and the plurality of terminal posts are respectively electrically connected to the plurality of connection members, thereby electrically connecting the driving board and the light sources. When the lamp tube needs to be maintained, since the connection end of the connection base and the power supply base are detachably connected, the power supply base can be directly removed from the connection end to maintain the electrical components such as the light sources connected to the connection base or the driving board inside the power supply base. When reassembly is required, directly align and connect the connection members on the power supply base with the terminal posts on the connection base. In this way, by using the alignment and electrical connection of the terminal posts and the connection members, the electrical connection between the lamp cap and the light sources in the external lamp tube is realized, effectively reducing the occurrence of adverse situations such as mis-touching of leads, and the power supply base and the connection base can be disassembled from each other to maintain the required parts respectively, greatly improving the convenience of maintaining the lamp tube and reducing the maintenance cost.

[0007] As a further improvement to the above technical solution, the terminal block includes a connecting section and a socket section that are interconnected. The connecting section is connected to the driver board, and the socket section has a circular cross-section. The terminal block is inserted into the socket section. When the terminal block is electrically connected to the terminal block, the terminal block is inserted into the circular socket section, achieving a hole-shaft fit. This improves the stability of the electrical connection between the two, enhances the stability between the power socket and the connecting socket, and makes the entire lamp holder connection structure more stable.

[0008] As a further improvement to the above technical solution, a boss is connected to the end face of the power socket facing the connection end, and a connection channel is provided at the position of the boss facing the terminal block, into which the socket section extends. A structure is formed on the power socket to limit the position of the socket section. After the terminal block is electrically connected to the driver board, the socket section of the terminal block can be inserted into the connection channel. This prevents the socket section from shifting when the terminal block is inserted into the socket section, greatly improving the stability of the terminal block during insertion.

[0009] As a further improvement to the above technical solution, the connecting section has an arcuate cross-section, with plugs connected to either side of the arc. The two plugs are plugged into the drive plate. Due to the arcuate cross-section of the connecting section, two fulcrums are formed on the two sides of the arc to support the drive plate, making it easy to position the connecting section and the drive plate. During assembly, the two plugs are directly inserted into the drive plate, achieving a quick connection between the two.

[0010] As a further improvement to the above technical solution, there are three binding posts arranged in a straight line, and the distances between the middle binding post and the binding posts at both ends are unequal. The three binding posts are used to connect the live wire, neutral wire, and communication line, respectively. Furthermore, among the three binding posts arranged in a straight line, the distances between the middle binding post and one end binding post are unequal, as are the distances between the middle binding post and the other end binding post. This prevents reverse connection when the three wiring members on the power socket are connected to the three binding posts, thereby improving the stability of the product assembly connection.

[0011] As a further improvement of the above technical solution, the power socket and the connecting socket are connected to each other via a buckle. The buckle connection between the power socket and the connecting socket enables quick assembly and disassembly, thereby improving the convenience of use and maintenance.

[0012] As a further improvement of the above technical solution, no less than two hooks are connected to the end of the power socket, and buckle blocks are respectively arranged at positions on the inner side of the connection seat opposite to at least two of the hooks, and at least two of the hooks are respectively buckled with at least two of the buckle blocks. When assembling the power socket and the connection seat, the hooks and the buckle blocks are aligned with each other, and then the power socket and the connection seat are brought closer to each other so that the hooks and the buckle blocks are tightly buckled together, so that the quick connection of the two can be realized.

[0013] As a further improvement of the above technical solution, a limiting rib is formed on the end face of the power socket opposite to the connection end, the limiting rib extends around the center line of the connection seat, and the limiting rib abuts against the inner side wall of the connection seat. When the power socket and the connection seat are assembled with each other, the limiting rib can be inserted into the connection seat and abut against the inner side wall of the connection seat, so that the quick alignment of the connection between the power socket and the connection seat can be carried out, and after the hooks and the buckle blocks are connected to each other, the relative lateral offset between the power socket and the connection seat can be effectively restricted, and the stability of the overall connection structure can be improved.

[0014] As a further improvement of the above technical solution, a partition piece is connected in the connection seat, and a plurality of terminal posts are respectively formed on the partition piece. The partition piece can support and position the plurality of terminal posts, and axially partition the internal space of the connection seat. The part of the space in the connection seat where the terminal posts are arranged is used for connecting with the power socket, while the other part of the space is used for connecting with an external pipe body.

[0015] A lamp tube includes a tube body and the above-mentioned lamp head, and one end of the connection seat far from the connection end is connected to the end of the tube body.

[0016] The technical solution has at least the following beneficial effects: Since the lamp tube is provided with the lamp head, when it is necessary to replace and maintain the lamp tube or the driving board and other structures after long-term use, the power socket and the connection seat can be disassembled from each other, and the parts needed can be maintained respectively, which greatly improves the convenience of maintaining the lamp tube and reduces the maintenance cost.

[0027] Refer to Figure 1 And Figure 2, A lamp holder includes a connection base 100 and a power supply base 200. Among them, one end of the connection base 100 is a connection end. A terminal post 110 extending towards the connection end is arranged inside the connection base 100, and the number of the terminal posts 110 is multiple; a driving board 210 is arranged inside the power supply base 200. A plurality of wiring components are arranged at the end of the power supply base 200 facing the connection end. The connection end is detachably connected to the power supply base 200, and the plurality of terminal posts 110 are respectively electrically connected to the plurality of wiring components.

[0028] As can be seen from the above, the connection base 100 is used to connect to the end of the tube body of the peripheral lamp tube. The light sources inside the lamp tube are respectively wired to the plurality of terminal posts 110, and the plurality of terminal posts 110 are respectively electrically connected to the plurality of wiring components, so as to electrically connect the driving board 210 and the light sources. When lamp tube maintenance is required, since the connection end of the connection base 100 and the power supply base 200 are detachably connected, the power supply base 200 can be directly removed from the connection end to maintain electrical components such as the light sources connected to the connection base 100 or the driving board 210 inside the power supply base 200. When reassembly is needed, directly align and connect the wiring components on the power supply base 200 with the terminal posts 110 on the connection base 100. In this way, by using the mutual alignment and electrical connection of the terminal posts 110 and the connection components, the electrical connection between the lamp holder and the light sources inside the peripheral lamp tube is realized, effectively reducing the occurrence of bad situations such as miscontact of leads, and the power supply base 200 and the connection base 100 can be disassembled from each other to respectively maintain the required parts, greatly improving the convenience of lamp tube maintenance and reducing the maintenance cost.

[0029] There are various ways to electrically connect the terminal post 110 and the wiring component. For example, directly abut the terminal post 110 against the wiring component for electrical connection, or hook the terminal post 110 and the wiring component tightly and then connect them electrically. In order to more stably connect the terminal post 110 and the wiring component electrically, in this embodiment, the wiring component includes a connection section 221 and a socket section 222 connected to each other. The connection section 221 is connected to the driving board 210. The cross-sectional shape of the socket section 222 is circular, and the terminal post 110 is inserted into the socket section 222. When the terminal post 110 and the wiring component are electrically connected, the terminal post 110 is inserted into the circular socket section 222 to achieve hole-shaft fit, so as to improve the stability of their electrical connection and enhance the stability between the power supply base 200 and the connection base 100, making the connection structure of the entire lamp holder more stable.

[0030] When the socket section 222 passes through the power supply base 200 outward, the end face of the power supply base 200 itself has a certain wall thickness, which can limit the socket section 222 to a certain extent. In order to further reduce the shaking of the socket section 222 when passing through the end face of the power supply base 200, such as Figure 3As shown, in this embodiment, a boss 230 is connected to the end face of the power socket 200 facing the connection end. A connection channel 231 is provided at the position of the boss 230 facing the wiring component, and the socket section 222 extends into the connection channel 231. A structure for limiting the socket section 222 is formed on the power socket 200. After electrically connecting the wiring component to the driving board 210, the socket section 222 of the wiring component can be inserted into the connection channel 231. In this way, when the terminal post 110 is inserted into the interior of the socket section 222, the socket section 222 is not easily displaced, greatly improving the stability when the terminal post 110 is inserted into the socket section 222.

[0031] The number of bosses 230 on the power socket 200 can be only one. At this time, connection channels 231 are respectively provided at the positions of one boss 230 facing multiple wiring components. The number of bosses 230 on the power socket 200 can also be multiple. Multiple bosses 230 are respectively provided corresponding to the positions of multiple wiring components. At this time, connection channels 231 are respectively provided at the positions of multiple bosses 230 facing multiple wiring components.

[0032] In the above embodiment, the connection section 221 can be the same as the socket section 222, and the entire wiring component forms a straight tube structure. However, at this time, the supporting area at the position where the connection section 221 is connected to the driving board 210 is small. In order to more stably connect the two to each other, as Figure 4 shown, in this embodiment, the cross-sectional shape of the connection section 221 is arc-shaped. Plug blocks 223 are respectively connected to both sides of the arc of the connection section 221, and the two plug blocks 223 are respectively inserted into the driving board 210. Since the cross-sectional shape of the connection section 221 is arc-shaped, two supporting points for supporting the driving board 210 are formed on the two side surfaces of the arc of the connection section 221, which can facilitate the positioning of the connection section 221 and the driving board 210. During assembly, the two plug blocks 223 are directly inserted into the driving board 210 to achieve quick positioning and connection of the two.

[0033] The number of terminal posts 110 can be two, three, four, etc. When the number of terminal posts 110 is three, the three terminal posts 110 are arranged in a straight line. Correspondingly, three wiring components are also arranged in a straight line. The distances between the middle terminal post 110 and the terminal posts 110 at both ends are not equal. The three terminal posts 110 are respectively used to connect the live wire, the neutral wire, and the communication wire. And between the three terminal posts 110 arranged in a straight line, the distance between the middle terminal post 110 and one end terminal post 110 and the distance between the middle terminal post 110 and the other end terminal post 110 are not equal. In this way, it can prevent the phenomenon of reverse connection when the three wiring components on the power socket 200 are docked with the three terminal posts 110, improving the stability of product assembly and connection.

[0034] There are various forms for the detachable connection between the power supply base 200 and the connection base 100. For example, the power supply base 200 and the connection base 100 are fixedly connected to each other by screws. In this embodiment, however, the power supply base 200 and the connection base 100 are connected to each other by snap fasteners. The snap connection between the power supply base 200 and the connection base 100 enables quick disassembly and assembly, improving the convenience of use and maintenance.

[0035] Similarly, there are various ways for the power supply base 200 and the connection base 100 to be connected to each other by snap fasteners. For example, one of a snap fastener or a snap groove is provided on the power supply base 200, and the other of the snap fastener or the snap groove is provided on the connection base 100. The power supply base 200 and the connection base 100 can be connected to each other by the snap fastener or the snap groove. In this embodiment, however, no less than two hooks 240 are connected to the end of the power supply base 200, and buckle blocks are respectively provided at positions on the inner side of the connection base 100 opposite to at least two of the hooks 240. At least two of the hooks 240 are respectively buckled with at least two of the buckle blocks. When assembling the power supply base 200 and the connection base 100 with each other, the hooks 240 and the buckle blocks are aligned with each other, and then the power supply base 200 and the connection base 100 are moved closer to each other, so that the hooks 240 and the buckle blocks are tightly buckled and matched with each other, thus enabling the quick connection of the two.

[0036] In order to further improve the stability of the connection between the power supply base 200 and the connection base 100 and improve the sealing performance of the connection between the two, in this embodiment, a limiting rib 250 is formed on the end face of the power supply base 200 facing the connection end. The limiting rib 250 extends around the center line of the connection base 100, and the limiting rib 250 abuts against the inner side wall of the connection base 100. When assembling the power supply base 200 and the connection base 100 with each other, the limiting rib 250 can be inserted into the connection base 100 and abut against the inner side wall of the connection base 100. In this way, the connection between the power supply base 200 and the connection base 100 can be quickly aligned. And after the hooks 240 and the buckle blocks are connected to each other, the relative lateral offset between the power supply base 200 and the connection base 100 can be effectively restricted, improving the stability of the overall connection structure. In practical applications, two hooks 240 can be provided at the end of the power supply base 200, and the two hooks 240 are symmetrically arranged with respect to the center line of the power supply base 200, and the limiting rib 250 can be formed between the two hooks 240.

[0037] Inside the connection base 100, a transverse support rib position can be connected, so that the terminal post 110 is connected to the support rib position. In order to better partition the space inside the connection base 100 and connect and fix the terminal post 110, in this embodiment, a partition piece is connected inside the connection base 100, and a plurality of the terminal posts 110 are respectively formed on the partition piece. The partition piece can support and position a plurality of terminal posts 110, and partition the space inside the connection base 100 axially. A part of the space inside the connection base 100 where the terminal post 110 is arranged is used to connect with the power supply base 200, and another part of the space is used to connect with the tube body of the peripheral device.

[0038] In order to connect the connection base 100 to the tube body of the peripheral lamp tube, the end of the connection base 100 far from the power supply base 200 can be designed with a smaller outer diameter, so that the connection base 100 can be conveniently connected and positioned. Or a limiting rib is arranged on the inner side wall of the end of the connection base 100 far from the power supply base 200. The limiting rib extends along the axis of the power supply base 200, and a plurality of them are circumferentially arrayed around the center of the power supply base 200, so as to be conveniently fastened to the tube body of the peripheral device.

[0039] A lamp tube includes a tube body and the above-mentioned lamp head, and one end of the connection base 100 far from the connection end is connected to the end of the tube body.

[0040] In this lamp tube, since the lamp head is provided on the tube body, when the lamp tube or the driving board 210 and other structures need to be replaced and maintained after long-term use, the power supply base 200 and the connection base 100 can be disassembled from each other, and the required parts can be maintained respectively, which greatly improves the convenience of maintaining the lamp tube and reduces the maintenance cost.

[0041] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
