BACKGROUND
-
Lighting devices has become an indispensable tool in daily life. It is applicable to various industries and fields, such as household lighting devices, commercial lighting devices, industrial lighting devices, and transportation lighting devices. A tri-proof lamp refers to a lighting device having waterproof, dustproof, and corrosion-resistant functions (namely the three protective functions). Such lighting devices are widely used in outdoor lighting, industrial production, warehouse storage, and other locations with relatively harsh environmental conditions. With the development of technology and changes in market demand, users have increasingly higher requirements for lighting devices, particularly with respect to protective performance.
-
Tri-proof lamps are favored due to their reliable performance in harsh environments. In order to improve the performance of tri-proof lamps and enhance user experience, continuous technological innovation is required, including improvements in structural design, material selection, and installation methods. In emergency rescue sites or locations where lighting devices need to be replaced quickly, the ability to rapidly and conveniently complete assembly and disassembly of the lighting devices is especially important.

The light source board 2 is installed in the chamber 10 of the lamp cover 1. The light source board 2 is rectangular in shape. One surface of the light source board 2 has a plurality of LEDs arranged in two rows.
-
The first end cap 3 covers the first opening 11. The first end cap 3 includes a sleeve cap 31 and a receiving portion 32. The overall shape of the sleeve cap 31 generally includes a semi-elliptical upper portion and a rectangular lower portion. The overall size of the sleeve cap 31 is larger than an outer diameter of the first opening 11. The sleeve cap 31 covers the outer side of the first opening 11 of the lamp cover 1. The sleeve cap 31 has a through hole, and a threaded portion 311 is disposed in the through hole for mounting and fixing the waterproof connector 36 and the rotary cap 37.
-
The threaded portion 311 of the first end cap 3 is connected to the waterproof connector 36 and the rotary cap 37, and a sealing ring 38 is clamped between the threaded portion 311 and the rotary cap 37 to provide the waterproof sealing function.
-
The receiving portion 32 of the first end cap 3 extends outwardly from one side of the sleeve cap 31. The receiving portion 32 is formed by a hollow housing 321. One side surface of the housing 321 is provided with a wire-passing hole 3211 corresponding to the wiring hole 61 of the wiring terminal 6. When the first end cap 3 is mounted to the first opening 11, the receiving portion 32 is disposed in the chamber 10, and one side surface 2a of one end of the light source board 2 abuts against the receiving portion 32 of the first end cap 3, thereby providing supporting and stabilizing functions.
-
In some embodiments, the receiving portion 32 includes two annular walls 324. The annular wall 324 are disposed on the two sides of the housing 321 respectively and extend in a curved manner toward each other.

In some embodiments, one surface of the sliding plate 5 has a latch portion 53. The latch portion 53 includes two hook-shaped latch feet 531 for engaging the guide slot 33 and achieving sliding fixation. In some embodiments, each of the two sides of the sliding plate 5 includes a side wing 54. Each side wing 54 corresponds to the inner side surface of the annular wall 324 corresponding thereto and provides sliding limitation. That is, when the sliding plate 5 and the wiring terminal 6 are assembled, the fixing hole 64 of the wiring terminal 6 is aligned with the central post 514 of the sliding plate 5, and the central post 514 extends through the fixing hole 64 to achieve positioning. Next, the limiting block 65 is inserted into the locking hole 515 of the sliding plate 5 to further secure the wiring terminal 6 in position. The sliding plate 5 slides into the guide slot 33 of the first end cap 3 through the hook-shaped latch feet 531 of the latch portion 53. During sliding, the side wings 54 closely abut against the inner side surfaces of the annular walls 324, so that the sliding plate 5 slides stably without disengagement. The wiring terminal 6 is pre-fixed to the sliding plate 5, and after the sliding plate 5 is in place, the wiring terminal 6 can be directly connected to the wiring hole 61 to achieve rapid assembly. Moreover, the wiring terminal 6 is quickly snapped into place without using screws, thereby improving installation efficiency. The design of the guide slot 33 of the sliding plate 5 ensures accurate and secure installation.
-
In some embodiments, the wiring terminal 6 is fixed to the supporting plate section 511 of the sliding plate 5. The body of the wiring terminal 6 includes the wiring hole 61, the fixing hole 64, and the limiting block 65. The wiring hole 61 corresponds to the wire-passing hole 3211 of the housing 321 for connecting wires. The central post 514 extends through the fixing hole 64 to achieve fixation. The limiting block 65 is inserted into the locking hole 515 to provide the limiting function.

In some embodiments, a power element 8 is fixedly connected to the tray 7. The power element 8 is connected to the light source board 2 and supplies electrical power to the light source board 2. The tray 7 is installed in the lamp cover 1. The tray 7 is an open box structure, and a cross section of the tray 7 is generally U-shaped. The rear surface of the tray 7 includes a plurality of first sliding latch portions 71 and a plurality of second sliding latch portions 72. Each of the first sliding latch portions 71 is a fixed hook-shaped structure, and each of the second sliding latch portions 72 is an elastic hook-shaped structure.

In some embodiments, the first sliding latch portions 71 are respectively disposed at equal intervals on the two side edges of the rear surface of the tray 7. The number of the second sliding latch portions 72 is two, and the second sliding latch portions 72 are respectively disposed at the central position of the rear surface of the tray 7. The light source board 2 has a plurality of first engaging grooves 21 and a plurality of second engaging grooves 22. Each of the first engaging grooves 21 is formed as a large hole communicating with a small hole. After each of the first sliding latch portions 71 is engaged with the large hole of the first engaging groove 21 corresponding thereto of the light source board 2, the tray 7 is slid toward one end so that each of the first sliding latch portions 71 is engaged with the small hole of the first engaging groove 21 corresponding thereto. Meanwhile, the hooks of the second sliding latch portions 72 elastically deflect and rebound to respectively engage the second engaging grooves 22 of the light source board 2, thereby achieving rapid assembly. When the power element 8 is fixed to the tray 7 for assembly, the power element 8 can be quickly installed on the light source board 2 through the tray 7 having a simplified structure. The first sliding latch portions 71 and the second sliding latch portions 72 are directly engaged with the first engaging grooves 21 and the second engaging grooves 22 of the light source board 2 without additional metal components, thereby reducing assembly steps and costs. Moreover, the latch-engagement design of the tray 7 for the power element 8 simplifies the currently available installation process, reduces components and costs, and improves reliability and user convenience of the lamp.
-
In summary, the tri-proof lamp 100 as a whole achieves rapid assembly through the conveniently pull-out wiring terminal 6, and through rapid assembly of the power element with the tray 7 and the light source board 2, thereby providing effects of quick and convenient assembly, improved production efficiency, increased production capacity, and reduced manufacturing costs. In addition, the wiring terminal 6 is quickly assembled without using conventional screw fastening, and is directly snapped and slid into place, making installation and use highly convenient. Conventional power elements require prior installation on a metal plate. The present solution reduces metal plate components and enables direct snap-fit assembly, thereby achieving convenience and efficiency.
