Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a lighting device. Background Technology

[0002] With the continuous development of society and the improvement of people's living standards, traditional candles, due to their production of smoke and carcinogens, are no longer the mainstream lighting tool and are gradually being replaced by similarly shaped candle lamps. Candle lamps can ensure the personal safety of users while creating an atmosphere. In order to charge multiple candle lamps simultaneously, candle lamps are equipped with candle holders. For example, Chinese patent document CN213513293U discloses a candle holder that can power four candle lamps at the same time. However, when the candle lamps are installed on the candle holder for charging, the charging interface on the candle lamp needs to be aligned with the conductive parts on the candle holder to achieve electrical connection, which is cumbersome and results in a poor user experience.

[0012] In one embodiment, the second power supply structure includes a rechargeable battery connected to the second circuit board and the second conductive post. When the first conductive post and the second conductive post are electrically connected, the rechargeable battery is charged.

[0013] In one embodiment, the candle lamp includes a warning light, which is electrically connected to the second circuit board and the second conductive post.

[0032] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] Reference Figure 1-4 This application provides a novel lighting device 1, which includes a charging base 10 and a candle lamp 20. The charging base 10 can supply power to the candle lamp 20, enabling the candle lamp 20 to store electricity and provide continuous illumination. Specifically, the charging base 10 includes a base 11 and a first power supply component 12 disposed within the base 11. The base 11 has a mounting surface 111. The first power supply component 12 includes a first circuit board 121 and a first conductive post 122 and a first power supply structure 123 electrically connected to the first circuit board 121. The first conductive post 122 passes through the base 11 and is exposed on the mounting surface 111 to form a charging position 13. The first power supply structure 123 provides charging power. A candle lamp 20 is installed in the charging position 13. The candle lamp 20 includes a lamp holder 21, a lamp tube 22, a lamp head 23, and a second power supply component 24. The lamp holder 21 and the lamp head 23 are respectively located at opposite ends of the lamp tube 22. The second power supply component 24 includes a second circuit board 241, a second conductive post 242 electrically connected to the second circuit board 241, and a second power supply structure 243. The second conductive post 242 is exposed outside the lamp holder 21, and the second circuit board 241 is electrically connected to the lamp head 23 through the second power supply structure 243. Both the first conductive post 122 and the second conductive post 242 include a positive conductive post (+) and a negative conductive post (-), such as... Figure 2 As shown in Figure 4, the positive terminal of the positive conductive post is indicated by the symbol "+", and the negative terminal of the negative conductive post is indicated by the symbol "-". The positive conductive post (+) of the first conductive post 122 is magnetically attracted and electrically connected to the positive conductive post (+) of the second conductive post 242, and the negative conductive post (-) of the first conductive post 122 is magnetically attracted and electrically connected to the negative conductive post (-) of the second conductive post 242. That is, the first conductive post 122 and the second conductive post 242 are magnetically attracted and electrically connected, so that the charging base 10 charges the candle lamp 20.

[0036] The lighting device 1 provided in this application includes a charging base 10 and a candle lamp 20. The positive and negative poles of the first conductive post 122 and the second conductive post 242 are magnetically attracted and electrically connected to each other to charge the candle lamp 20. In this application, the dual connection functions of magnetic attraction and electrical connection are integrated into the first conductive post 122 and the second conductive post 242, which greatly saves materials related to the positioning, assembly, and circuit connection between the charging base 10 and the candle lamp 20. On the one hand, when the candle lamp 20 needs to be charged, the user only needs to bring the lamp holder 21 of the candle lamp 20 close to the mounting surface 111. The magnetic attraction between the first conductive post 122 and the second conductive post 242 can automatically position and install the candle lamp 20 in the charging position 13 without the user needing to align it manually. On the other hand, the first conductive post 122 and the second conductive post 242 are magnetically connected and electrically connected to conduct the first power supply component 12 and the second power supply component 24 to charge the candle lamp 20. It is understandable that one of the first conductive post 122 and the second conductive post 242 can be a magnetic post and the other can be a metal post, so that they can be aligned magnetically attracted and electrically connected; or, both the first conductive post 122 and the second conductive post 242 can be magnetic posts, so that they can also be aligned magnetically attracted and electrically connected.

[0037] Optionally, refer to Figure 2 In one embodiment, the base 11 includes a detachably connected upper shell 112 and a lower shell 113, which together form a mounting cavity 114. The first power supply component 12 is housed within the mounting cavity 114 and fixed to the upper shell 112. The mounting cavity 114 protects the first power supply component 12 from water and dust, and the detachable upper shell 112 and lower shell 113 facilitate the inspection and processing of the first power supply component 12. Of course, in other embodiments, the upper shell 112 and lower shell 113 may also be an integrally formed structure.

[0038] Preferably, in conjunction with reference Figure 1 and Figure 4In one embodiment, the mounting surface 111 is provided with a charging slot 14. The candle lamp 20 is inserted into the charging slot 14 along the axial direction of the lamp tube 22. The charging position 13 is located at the bottom of the charging slot 14. The first conductive post 122 extends out of the bottom wall of the charging slot 14 and is aligned and magnetically attracted to the second conductive post 242 along the axial direction of the lamp tube 22, and is electrically connected. It can be understood that the axial directions of the first conductive post 122 and the second conductive post 242 are both parallel to the axial direction of the lamp tube 22, and the depth direction of the charging slot 14 is also parallel to the axial direction of the lamp tube 22. In other embodiments, the axial directions of the first conductive post 122 and the second conductive post 242 may not be parallel to the axial direction of the lamp tube 22. They may also be magnetically attracted and electrically connected on the side wall of the charging slot 14, that is, the axial directions of the two conductive posts are not limited. In addition, the charging slot 14 can protect the charging position 13 from being exposed. In other embodiments, the charging slot 14 may not be provided, as long as the two conductive posts are aligned, magnetically attracted, and electrically connected.

[0039] Preferably, in conjunction with reference Figure 4-6 In one embodiment, one of the bottom wall of the charging slot 14 and the outer wall of the lamp holder 21 is provided with a positioning groove 25, and the other is provided with a positioning protrusion 15. When the candle lamp 20 is inserted into the charging slot 14, the positioning protrusion 15 is aligned and engaged with the positioning groove 25 to improve the assembly stability between the candle lamp 20 and the charging holder 10 and enhance the electrical contact stability between the first conductive post 122 and the second conductive post 242 (in combination). Figure 4 In this configuration, when the positioning groove 25 is located on the lamp holder 21, the positioning protrusion 15 is located on the bottom wall of the charging slot 14. The positioning groove 25 is spaced apart from the second conductive post 242, and the positioning protrusion 15 is spaced apart from the first conductive post 122. When the positioning groove 25 is located on the bottom wall of the charging slot 14, the positioning protrusion 15 is located on the lamp holder 21. The positioning groove 25 is spaced apart from the first conductive post 122, and the positioning protrusion 15 is spaced apart from the second conductive post 242. It should be noted that in other embodiments, the positioning groove 25 and positioning protrusion 15 may not be necessary to improve assembly stability; the candle lamp 20 inserted into the charging slot 14 itself improves assembly stability.

[0040] Furthermore, in conjunction with references Figure 4-6 In one embodiment, the lamp holder 21 is recessed into one end of the lamp tube 22, such that the lamp tube 22 forms a first recessed groove 26 at the end facing away from the lamp head 23. Figure 5The diagram illustrates that a plurality of protrusions 16 are circumferentially protruding around the bottom of the charging slot 14, each protrusion 16 being spaced apart from the inner sidewall of the charging slot 14. When the candle lamp 20 is inserted into the charging slot 14, each protrusion 16 abuts against the inner sidewall of the first recessed groove 26 radially outward along the charging slot 14. The side circumference of the first recessed groove 26 is sandwiched between the protrusion 16 and the inner sidewall of the charging slot 14, thereby further improving the assembly stability of the candle lamp 20 and the charging base 10. The second conductive post 242 does not protrude from the opening of the first recessed groove 26 to prevent the lamp base 21 from failing to stably support the candle lamp 20 on the plane. It should be noted that, without considering the magnitude of assembly stability, in other embodiments, the first recessed groove 26 and the protrusions 16 may not be required.

[0041] Optionally, in conjunction with reference Figure 1 and Figure 2 In one embodiment, the first power supply structure 123 includes a charging interface 123a. One end of the charging interface 123a passes through the base 11 and is electrically connected to the first circuit board 121. The other end of the charging interface 123a is exposed outside the base 11 for an external power source. The charging interface 123a includes, but is not limited to, a Type-C interface, a USB interface, a round hole, or an Apple interface. In other embodiments, the charging interface 123a is not provided. The first power supply structure 123 includes a battery, which is disposed inside the base 11 and electrically connected to the first circuit board 121. The battery supplies power to the charging dock 10. Additionally, the first power supply structure 123 may also include a charging cable for an external power source.

[0042] Optionally, refer to Figure 3 In one embodiment, the second power supply structure 243 includes a rechargeable battery 243a, which is electrically connected to the second circuit board 241 and the second conductive post 242. When the first conductive post 122 is electrically connected to the second conductive post 242, the rechargeable battery 243a is charged. After being fully charged, the candle lamp 20 can be detached from the charging base 10 for independent use. It should be noted that in other embodiments, the rechargeable battery 243a may not be required. The second power supply structure 243 includes wires, and when the candle lamp 20 is installed on the charging position 13, the candle lamp 20 can be directly powered for illumination. The second power supply structure 243 can also store electricity through a capacitor.

[0043] Optionally, refer to Figure 3In one embodiment, the candle lamp 20 further includes a warning light 27, which is electrically connected to the second circuit board 241 and the second conductive post 242. When the first conductive post 122 is electrically connected to the second conductive post 242, the rechargeable battery 243a begins charging, and the warning light 27 illuminates, reminding the user that the candle lamp 20 is charging. When the first conductive post 122 is disconnected from the second conductive post 242, the rechargeable battery 243a stops charging, and the warning light 27 turns off, reminding the user that the candle lamp 20 is not charging. The warning light 27 serves as a charging reminder; in other embodiments, it may not be necessary.

[0044] Optionally, in conjunction with reference Figure 3 and Figure 6 In one embodiment, the candle lamp 20 is equipped with a dimming module 28, which includes a dimming button 281 and a control chip (not shown). Both the dimming button 281 and the control chip are electrically connected to the second circuit board 241. Operating the dimming button 281 causes the control chip to cycle through three modes: off, first light intensity, and second light intensity. The brightness of the lamp head 23 in the first light intensity mode is lower than that in the second light intensity mode. The specific control process is as follows: when the lamp head 23 is off, the user presses the dimming button 281 once, and the lamp head 23 illuminates; pressing the dimming button 281 again continues to illuminate the lamp head 23 with increased brightness; pressing the dimming button 281 again turns the lamp head 23 off, returning to the initial state. Of course, in other embodiments, the brightness of the lamp head 23 can also be cycled by sliding or toggling the dimming button; alternatively, the light intensity of the lamp head 23 does not need to be set to an adjustable mode; a single brightness mode is also acceptable.

[0045] Optionally, in conjunction with reference Figure 2 and Figure 6 In one embodiment, the dimming button 281 and the second conductive post 242 are spaced apart on the same side of the lamp holder 21 away from the lamp head 23. The bottom surface of the lamp holder 21 facing away from the lamp head 23 is recessed to form a second recessed groove 29. The dimming button 281 is exposed on the bottom wall of the second recessed groove 29 and does not protrude from the opening of the second recessed groove 29, so as to prevent the lamp holder 21 from being unable to stably support the candle lamp 20 on the plane due to the protrusion of the dimming button 281. Of course, if the first recessed groove 26 is deep enough, the second recessed groove 29 may not be provided. In this case, the dimming button 281 is exposed on the bottom wall of the first recessed groove 26 and does not protrude from the opening of the first recessed groove 26.

[0046] Optionally, in conjunction with reference Figure 1 and Figure 2In one embodiment, there are multiple first conductive posts 122 and charging positions 13, with the multiple charging positions 13 (corresponding to charging slots 14) distributed in an array at intervals on the mounting surface 111; and / or, there are multiple candle lamps 20. Here, multiple candle lamps 20 are charged on multiple charging positions 13, allowing the user to use multiple candle lamps 20 at once, or the charging base 10 to charge multiple candle lamps 20 at once, making the lighting device 1 of this application adaptable to more usage scenarios and more practical. Of course, in other embodiments, the lighting device 1 may also consist of one charging position 13 and one candle lamp 20.

[0047] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
