[0029] refer to Figure 1-Figure 6 As shown, in the embodiment of the utility model, a lamp is proposed, which is mainly suitable for occasions where the internal cable and the external cable of the lamp are connected through a wiring connector. The wiring connector belongs to the prior art and will not be described in detail here. It can be understood that the lamp can be used in general occasions where lighting is required, and can also be used in special occasions where the sealing performance of the lamp itself is required to be high. In other words, whether the lamp has a sealing structure is not a limitation of the embodiment of the utility model.

[0030] The lamp includes a lampshade 10, a connection seat 20 and a locking structure. The lampshade 10 is set as a closed structure, and a cavity is set inside it. The cavity is installed with structures including but not limited to a light source and internal cables connected to the light source. The light source can be an LED light board or a lamp tube, a lamp bead, etc., and no specific restrictions are made here. In order to quickly connect the internal cable with the external cable outside the lampshade, a threading opening connecting the cavity and the outside is opened on the lampshade 10. The locking structure is configured to fix the connection seat 20 in the lampshade 10. The connection seat 20 is provided with a threaded hole 24 coaxial with the threading opening, and the wiring connector can pass through the threading opening and be threadedly connected to the connection seat 20.

[0031] In the above-mentioned lamp, a locking structure is used to fix the connecting base 20 with a threaded hole 24 inside the lampshade 10. When connecting the internal cable and the external cable, it is only necessary to lead the internal cable out of the lampshade 10 through the threading opening and connect it to the external cable on the wiring connector, and then insert the wiring connector into the cavity through the threading opening. The connection between the wiring connector and the connecting base 20 can be achieved by screwing the wiring connector. The wiring connector can be assembled on the lampshade 10 without opening the lampshade 10. The operation is simple and the assembly time is short.

[0032] It is understandable that the threading opening can be provided on the side wall of the lampshade 10 , or on the top wall or the bottom wall of the lampshade 10 .

[0033] refer to Figure 1 As shown, in some embodiments, the lampshade 10 is in the shape of a long strip extending along a first direction (X direction in the figure), and its cross-sectional shape along a second direction (Z direction in the figure) can be circular, rectangular or other shapes, without specific limitation here, and the second direction is perpendicular to the first direction. Specifically, the lampshade 10 includes a first shell 11 and a second shell 12 distributed along the second direction, wherein the first shell 11 has an opening toward the second shell 12, and the second shell 12 has an opening toward the first shell 11, and the first shell 11 and the second shell 12 are connected by means including but not limited to snap-fitting and screwing to enclose and form a cavity, and when a seal is required, a sealing ring is also provided between the first shell 11 and the second shell 12.

[0034] refer to Figure 2 As shown, in some embodiments, the locking structure includes a fixing ear 90, a connecting column 100 and a fastener (not shown in the figure), wherein the fixing ear 90 is arranged on the connecting seat 20, and a fixing hole 91 for the fastener to pass through is opened on the fixing ear 90, and the connecting column 100 is integrally formed on the lampshade 10, and a threaded connection hole for the fastener to pass through is axially arranged on the connecting column 100, and the fastener passes through the fixing hole 91 and the threaded connection hole to fix the fixing ear 90 and the connecting column 100 together, thereby fixing the connecting seat 20. The fastener is preferably a bolt.

[0035] In order to improve the stability of the connection base 20, two connection posts 100 and two fixing ears 90 are provided, wherein the two fixing ears 90 can be provided on the side of the connection base 20 facing away from the threading opening, or on both sides of the connection base 20 along the third direction (Y direction in the figure). The connection posts 100 are provided on the bottom wall of the lampshade 10 at intervals along the third direction and correspond to the fixing ears 90, and the third direction is perpendicular to the first direction and the second direction.

[0036] Considering the limited space in the lampshade 10, the connecting base 20 should be as thin as possible while ensuring structural strength and fixing the wiring joints. Therefore, the fixing ear 90 is preferably arranged on the side of the connecting base 20 facing away from the threading opening, and is preferably welded to the connecting base 20.

[0037] Specifically, the two fixing ears 90 are symmetrically arranged on opposite sides of the threaded hole 24 . To ensure uniform force when the wiring connector is screwed, the axes of the fixing ears 90 and the threaded hole 24 are on the same straight line, and the connecting column 100 abuts against the fixing ears 90 .

[0038] refer to Figure 2 As shown, in order to improve the structural strength of the connecting column 100, a plurality of triangular reinforcing ribs are provided along the circumferential direction at one end of the connecting column 100 connected to the bottom wall of the lampshade 10.

[0039] In order to reduce weight and cost while ensuring the structural strength of the connection base 20, refer to Figure 3 As shown, in some embodiments, a plurality of first weight reducing grooves 22 are arranged around the threaded hole 24 on the side of the connecting seat 20 facing away from the threading opening. The shapes of the first weight reducing grooves 22 may be the same or different, and are not specifically limited in the embodiments of the utility model. However, it should be noted that the side of the first weight reducing grooves 22 facing the threaded hole 24 is arc-shaped and together form an annular structure, and threads are arranged on the inner wall of the annular structure to form the threaded hole 24. At this time, the groove wall shared by adjacent first weight reducing grooves 22 serves as a reinforcing rib, which can ensure the structural strength of the entire connecting seat 20, especially near the threaded hole 24.

[0040] refer to Figure 4 As shown, in some embodiments, a plurality of second weight-reducing grooves 23 are provided around the threaded hole 24 on one side of the connection seat 20 facing the threading opening, and each second weight-reducing groove 23 has the same shape and is located on the end surface of the annular structure.

[0041] In some embodiments, in order to prevent foreign matter from entering the interior of the lamp through the threading opening during transportation or storage, the lamp further includes a cover 40, which is detachably connected to the lampshade 10 and seals the threading opening. For example, the outer peripheral surface of the cover 40 has an external thread, and the cover 40 can be inserted into the threading opening and threadedly connected to the connection seat 20.

[0042] refer to Figure 5 and Figure 6 As shown, in some embodiments, the cover 40 can be made of existing screws, such as cross-slot screws. When wiring is required, the cover 40 can be screwed off from the lampshade 10.

[0043] It is understandable that when wiring, the internal cable in the lampshade 10 needs to be led out from the lampshade 10, then connected to the external cable on the wiring connector, and then plugged back into the lampshade 10. Therefore, in some embodiments, the blind cover 40 is detachably connected to the internal cable. For example, a slot for inserting the internal cable is provided at one end of the blind cover 40 inserted into the lampshade 10, and the end of the internal cable away from the light source is inserted into the slot. When the blind cover 40 is separated from the lampshade 10 and moves in a direction away from the lampshade 10, the end of the internal cable away from the power source moves with the blind cover 40, thereby passing through the lampshade 10.

[0044] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
