Description

Technical Field

[0001] The invention relates to the technical field of lighting, and in particular to a waterproof structure of a narrow-edge lamp. Background Art

[0002] A Chinese utility model patent (publication number CN205579518U) discloses a sealed waterproof structure of a lamp with a light emitting diode as a light source. Specifically, the following contents are disclosed in the specification: Figures 1 to 3 As shown, the sealing waterproof structure of the lamp with the light emitting diode as the light source of this embodiment is located at the end of the lamp holder body, and is used to seal and encapsulate the light emitting diode lamp assembly at the end of the lamp holder body. The waterproof structure includes a metal cover, tempered glass and a sealing ring made of silicone material. The sealing ring is placed in the end surface mounting groove of the lamp holder body. The metal cover installs the tempered glass and the sealing ring at the end of the lamp holder body through screws; the sealing ring has an annular placement groove for placing the tempered glass and an upper round through hole and a lower round through hole connected to the upper and lower ends of the annular placement groove. The lower surface of the sealing ring has a wavy sealing surface, and the wavy sealing surface is in airtight contact with the end surface mounting groove of the lamp holder body. During installation, the tempered glass and the sealing ring are assembled together and placed in the end surface mounting groove of the lamp holder body, and the metal cover is assembled on the top of the sealing ring and fixed with screws. As can be seen from the above, the above technical solution has the following defects: the metal cover is pressed and fixed to the sealing ring by screws passing through the metal panel for locking. In order to leave enough installation space for the screws, the thickness of the metal panel and the frame thickness of the lamp holder body must be made large enough, thereby causing the overall volume of the lamp body to become larger, further leading to high cost of consumables of the product, inconvenient packaging and transportation, and other problems. Summary of the invention

[0003] The present invention is to solve one of the above-mentioned technical problems and provide a waterproof structure of a narrow-edge lamp, which has the advantages of lighter volume, lower consumables cost and more convenient packaging.

[0006] As a preferred embodiment, it is further defined that a plurality of columnar portions integrally formed with the first sealing ring are distributed around the first sealing ring, the columnar portion extends from the upper end of the first sealing ring through the annular placement groove to its lower end, and the through hole is penetrated through the columnar portion so that the through hole is not connected to the annular placement groove.

[0007] As a preferred embodiment, it is further defined that the outer periphery of the tempered glass is provided with a plurality of avoidance notches which are engaged with the columnar parts in a one-to-one correspondence.

[0008] As a preferred embodiment, it is further defined that both the upper end surface and the lower end surface of the first sealing ring are provided with an annular raised strip.

[0009] As a preferred embodiment, it is further defined that the lamp holder body includes a seat body and a base, the lower end of the seat body is provided with a first groove, and the upper end of the base is provided with a second groove corresponding to the first groove, when the seat body and the base are fixedly connected, the first groove and the second groove are combined to form a waterproof groove, and the waterproof groove accommodates a second sealing ring.

[0010] After adopting the above technical solution, the invention has at least the following beneficial effects: the through hole through which the screw passes can well fix the annular upper cover and the first sealing ring on the lamp holder body, so it is only necessary to reserve a spacing slightly larger than the diameter of the screw on the lamp holder body and the annular upper cover to complete the fixing of the first sealing ring; compared with the prior art, the spacing of the lamp frame of the invention can be made narrower, making the overall lamp body lighter, the consumables cost lower, and the packaging more convenient. In addition, the screw passing through the first sealing ring can well limit the huge deformation of the first sealing ring due to thermal expansion and contraction, and effectively prevent the first sealing ring from causing water to enter the lamp due to deformation.

[0018] As attached Figure 1 To Attachment Figure 4 , Attachment Figure 6 As shown, a waterproof structure of a narrow-edge lamp comprises a lamp holder body 1, wherein the lamp holder body 1 has a light outlet, and an annular mounting groove 10 is arranged around the lamp holder body 1 and located at the light outlet, and a first sealing ring 2 is adapted to be arranged in the annular mounting groove 10, and an annular placement groove 20 with a notch facing the center of the ring is opened on the inner side of the ring of the first sealing ring 2, and a tempered glass 3 is placed in the annular placement groove 20 so that the tempered glass 3 closes the light outlet, and an annular upper cover 4 is arranged on the lamp holder body 1 and located at the notch of the annular mounting groove 10, and a plurality of axially extending grooves are arranged around the end of the first sealing ring 2. A through hole 21 is provided in a direction that passes through the annular placement groove 20 and is not connected to the annular placement groove 20. The through hole 21 is used for screws to pass through. The screws pass through the annular upper cover 4 and the through hole 21 in sequence and are fixedly connected to the lamp holder body 1. After the screw passes through the through hole 21, the annular upper cover 4 and the first sealing ring 2 can be well fixed to the lamp holder body 1. Therefore, it is only necessary to reserve a spacing slightly larger than the diameter of the screw on the lamp holder body 1 and the annular upper cover 4 to complete the fixing of the first sealing ring 2. Compared with the prior art, the spacing of the lamp frame of the present invention can be made narrower, making the overall lamp body lighter, the consumables cost lower, and the packaging more convenient. In addition, the screw passing through the first sealing ring 2 can well limit the huge deformation of the first sealing ring 2 due to thermal expansion and contraction, and effectively prevent the first sealing ring 2 from causing water to enter the lamp due to deformation.
