[0035] FIG1 is a schematic structural diagram of a lamp provided in an embodiment of the present application, and FIG2 is a schematic structural diagram of a lamp housing of the lamp shown in FIG1 .

[0036] As shown in Figures 1 to 2, an embodiment of the present application provides a lamp, which includes a light strip and a lamp housing 1 made of plastic. The lamp housing 1 includes an integrally formed base 11 and a light-transmitting portion 12. The base 11 and the light-transmitting portion 12 are arranged to form a receiving cavity and an opening connected to the receiving cavity. The base 11 is formed with a mounting portion 13, which is located in the receiving cavity. The mounting portion 13 includes an integrally formed connecting portion 131 and a clamping portion 132. The connecting portion 131 is arranged to be arc-shaped and recessed toward the base 11. The clamping portion 132 is located in the inner cavity of the connecting portion 131. The clamping portion 132 and the connecting portion 131 form a clamping groove 1321, which is used to clamp the light strip.

[0037] It should be understood that the lighting fixture includes a light bar, which is long and strip-shaped and is equipped with multiple lamp beads, which are spaced apart along the length of the light bar. The lamp housing 1 is also long and strip-shaped and is made of plastic, which is an insulating material to avoid the risk of leakage from the wires of the lamp housing 1.

[0038] The lamp housing 1 includes a base 11 and a light-transmitting portion 12. The base 11 and the light-transmitting portion 12 are both made of plastic and are integrally molded. The light-transmitting portion 12 can be arc-shaped or rectangular with an inner cavity. This application does not limit the shape of the light-transmitting portion 12.

[0039] The light-transmitting portion 12 can transmit light, while the base 11 can block light, thereby concentrating the light emitted by the lamp and increasing the brightness. In one example, the light-transmitting portion 12 can be injection-molded using a light-transmitting material, such as polycarbonate (PC) or polymethyl methacrylate (PMMA), and then the light-transmitting portion 12 can be integrally injection-molded with the base 11 as an insert. The base 11 can be injection-molded using a non-light-transmitting material, such as nylon (PA), or the light-transmitting material can be mixed with an opaque material. In another example, the base 11 and the light-transmitting portion 12 can both be integrally injection-molded using a light-transmitting material, and then the outer surface of the base 11 can be coated with a light-shielding paint.

[0040] The lamp housing 1 also includes a mounting portion 13, which is integrally formed with the base 11 and is located in the accommodating cavity. The mounting portion 13 includes an integrally formed connecting portion 131 and a clamping portion 132. The connecting portion 131 is recessed in an arc shape toward the base 11. The clamping portion 132 is located on the side of the connecting portion 131 facing the light-transmitting portion 12. Two clamping portions 132 are provided and are arranged at intervals along the width direction of the lamp housing 1. The two clamping portions 132 and the connecting portion 131 form a clamping groove 1321. The light strip is installed in the clamping groove 1321, thereby clamping the light strip in the lamp housing 1.

[0041] During installation, the light bar is simply inserted from the opening into the accommodating cavity, and then into the slot 1321, thereby connecting the light bar to the mounting portion 13. Compared to existing installation methods, this reduces the number of installation steps and improves installation convenience. Furthermore, because the connecting portion 131 is recessed in an arc shape toward the base 11, the light from the light bar is focused toward the light-transmitting portion 12, thereby increasing the brightness of the lamp.

[0042] Furthermore, the mounting portion 13 is located at the connection between the base 11 and the light-transmitting portion 12 , so as not to affect the lighting effect of the lamp.

[0043] In some optional embodiments, the connection portion 131 is provided with a clearance opening 1311 at each end along the length of the lamp housing 1. The clearance opening 1311 is used to allow the light bar wiring harness to pass through. The provision of the clearance opening 1311 facilitates the connection between the wiring harness and the light bar. The wiring harness is an electrical wire, namely a neutral wire, a live wire, and a bottom wire. The wiring harness can be welded to the light bar at the clearance opening 1311, thereby powering the light bar and controlling the light bar's on / off function.

[0044] In some optional embodiments, the lamp housing 1 is provided with openings at both ends along its length. The provision of the openings facilitates the installation of the light strip and the connection of the lamp to another lamp, thereby increasing the length of the lamp.

[0045] 1 and 3 - 4 , FIG3 shows a structural schematic diagram 1 of an adapter of the lamp shown in FIG1 , and FIG4 shows a structural schematic diagram 2 of an adapter of the lamp shown in FIG1 .

[0046] In some optional embodiments, an adapter assembly 2 is further included, which includes an adapter seat 21 and an adapter joint 22. The adapter seat 21 covers the opening of the lamp housing 1, and the adapter seat 21 is provided with a first wire passing hole, which is connected to the accommodating cavity of the lamp housing 1. The adapter seat 21 is provided with a mounting groove 211 adapted for the adapter joint 22, and the adapter joint 22 is provided with a second wire passing hole, which is connected to the second wire passing hole.

[0047] The adapter seat 21 is adapted to the adapter 22, and the length of the adapter 22 is equal to the length of the two mounting grooves 211, that is, one end of the adapter 22 extends into the mounting groove 211 of one adapter seat 21, and the other end of the adapter 22 extends into the mounting groove 211 of the other adapter seat 21, thereby connecting the two adapter seats 21.

[0048] To connect two lamps, first connect the two adapters 21 to the ends of the two lamp housings 1, respectively, so that the wiring harness connected to the light bar extends from the accommodating cavity and into the first wire hole of the adapter 21. Then, insert the two ends of the adapter 22 into the mounting slots 211 of the two adapters 21, respectively, so that the second wire hole of the adapter 22 corresponds to and connects with the first wire hole. The wiring harness of one light bar passes through the second wire hole and the first wire hole, extends into the other accommodating cavity, and connects to the light bar in the other lamp housing 1. Thus, the two lamps are connected.

[0049] 1-4 , in some optional embodiments, a first engaging portion 111 is provided at the bottom of the base 11 , and a second engaging portion 212 is provided at the bottom of the adapter 21 . The first engaging portion 111 is configured to engage with the first engaging portion 111 .

[0050] In one example, the first snap-fit ​​portion 111 is a buckle and the second snap-fit ​​portion 212 is a bayonet. During installation, the first snap-fit ​​portion 111 and the second snap-fit ​​portion 212 are snap-fitted and fixed, thereby snapping the bottom of the base 11 to the bottom of the adapter 21, thereby fixing the adapter 21 to the lamp housing 1.

[0051] In some optional embodiments, the first engaging portion 111 is a bayonet, the second engaging portion 212 is a buckle, and the thickness of the second engaging portion 212 gradually decreases toward the lamp housing 1. During installation, the first engaging portion 111 and the second engaging portion 212 are engaged and fixed. Since the thickness of the second engaging portion 212 gradually decreases toward the lamp housing 1, it is easier for the second engaging portion 212 to extend into the first engaging portion 111, and the probability of the second engaging portion 212 being separated from the first engaging portion 111 is reduced.

[0052] In some optional embodiments, a third engaging portion 112 is provided on the side of the base 11 , and a fourth engaging portion 213 is provided on the side of the adapter 21 , and the third engaging portion 112 is engaged with the fourth engaging portion 213 .

[0053] A third locking portion 112 is provided on the side of the base 11, and two third locking portions 112 are provided and are respectively located on two opposite sides of the base 11. Two fourth locking portions 213 are provided and are respectively located on two opposite sides of the adapter 21. When the third locking portion 112 and the fourth locking portion 213 are engaged, the two side surfaces of the base 11 and the two side surfaces of the adapter 21 are engaged and fixed, thereby preventing the output wires of the base 11 and the adapter 21 from shaking, thereby improving the stability of the connection between the base 11 and the adapter 21.

[0054] In one example, the third engaging portion 112 is a slot, and the fourth engaging portion 213 is a block. When the fourth engaging portion 213 extends into the third engaging portion 112 , the adapter 21 is connected to the lamp housing 1 .

[0055] In one example, the third engaging portion 112 is a block, the fourth engaging portion 213 is a slot with its opening facing the mounting portion 13 , and when the third engaging portion 112 extends into the fourth engaging portion 213 , the third engaging portion 112 is located in the accommodating cavity, and the adapter 21 is connected to the lamp housing 1 .

[0056] In some optional embodiments, a support plate 214 is provided on the side of the adapter 21 facing the lamp housing 1. The support plate 214 is provided with reinforcing ribs 215. The support plate 214 protects the interior of the adapter 21. When the adapter 21 and the lamp housing 1 are installed, the support plate 214 extends into the accommodating cavity. The provision of the reinforcing ribs 215 enhances the strength of the support plate 214. The reinforcing ribs 215 are cylindrical and extend along the length of the adapter 21. The reinforcing ribs 215 also enhance the secure connection between the adapter 21 and the base 11.

[0057] In some optional embodiments, the adapter 21 is further provided with a partition 216. There are multiple second wire holes, and the partition 216 is located between two adjacent second wire holes. The provision of the partition 216 avoids mutual interference between multiple wire harnesses and improves the safety of the lamp.

[0058] In one example, three second wire holes are provided, and two partitions 216 are provided. The two partitions 216 separate the three wire holes, thereby separating the live wire, the neutral wire, and the bottom wire of the wiring harness to prevent mutual influence between the three.

[0059] In some optional embodiments, the adapter 21 and adapter 22 are each a light-transmitting structural member. The adapter 21 and adapter 22 can be made of a light-transmitting PC material. When two lamps are connected, the material selection of the adapter assembly 2 allows light to pass through the connection, avoiding the occurrence of shadows at the connection and improving the lighting effect of the lamp.

[0060] The present application also includes a combination lamp, including at least two lamps spliced ​​together, the lamp being any of the lamps described above. The present application does not limit the number of lamps, and the lamps can be two, three, or more.

[0061] In some optional embodiments, the lamp includes an adapter assembly 2 , which includes an adapter seat 21 and an adapter joint 22 . The adapter seat 21 of one lamp is connected to the adapter seat 21 of another lamp via the adapter joint 22 .

[0062] When splicing two adjacent lamps, first connect the two adapters 21 to the ends of the two lamp housings 1, respectively, so that the wiring harness connected to the light bar extends from the accommodating cavity and extends into the first wire hole of the adapter 21. Then, insert the two ends of the adapter 22 into the mounting slots 211 of the two adapters 21, respectively, so that the second wire hole of the adapter 22 corresponds to and connects with the first wire hole. The wiring harness of one light bar passes through the second wire hole and the first wire hole, extends into the other accommodating cavity, and connects to the light bar in the other lamp housing 1. Thus, the two lamps are connected.
