[0016] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0017] like Figures 1-2As shown, this embodiment provides a lighting fixture with a waterproof structure, specifically including: a chassis 1, an outer frame 2, a power supply box 3, an inner frame 4, and a diffuser plate 5; the outer frame 2 is installed on the edge of the chassis 1, the diffuser plate 5 is installed on one side of the chassis 1, and the diffuser plate 5 is sandwiched between the outer frame 2 and the chassis 1 on all four sides; the inner frame 4 is installed on the side of the diffuser plate 5 facing the chassis 1, and the inner frame 4 is located inside the edge of the chassis 1; the chassis 1 and the outer frame 2 are sealed together, and the inner frame 4, the chassis 1, and the diffuser plate 5 are also sealed together. The power supply box 3 is installed on the chassis 1 or the outer frame 2, and a power supply and driving assembly are installed inside the power supply box 3; a lighting assembly is installed between the diffuser plate 5 and the chassis 1, and the lighting assembly is connected to the power supply and driving assembly.

[0018] like Figure 3 As shown, the chassis 1 includes: a chassis inclined surface 101, an arc surface 102, a first groove 103, and a baffle plate 104; the chassis inclined surface 101 extending outward is provided on the periphery of the end face of the chassis 1, the outer side of the chassis inclined surface 101 is connected to the arc surface 102, the outer side of the arc surface 102 is connected to the first groove 103, and the edge of the first groove 103 is provided with a baffle plate 104 extending outward. The first groove 103 is generally trapezoidal in shape, the baffle plate 104 is one side of the first groove 103, and the opening of the first groove 103 faces the boss 202 of the outer frame 2.

[0019] like Figure 4 As shown, the outer frame 2 includes: a limiting plate 201, a boss 202, a second groove 203, and a side frame 204; one end of the limiting plate 201 is connected to an upwardly protruding boss 202, and the other side of the boss 202 is set as the side frame 204, and the second groove 203 is formed between the side frame 204 and the boss 202.

[0020] More specifically, the first groove 103 is fastened to the boss 202, and the top of the boss 202 abuts against the inner wall of the first groove 103. The baffle plate 104 extends into the second groove 203 and abuts against the side of the frame 204. The arc surface 102 protrudes towards the limiting plate 201 and is clamped with the limiting plate 201 on both sides of the edge of the diffuser plate 5. The cavity formed by the boss 202, the diffuser plate 5, and the arc surface 102 is sealed; the cavity formed by the chassis inclined surface 101, the diffuser plate 5, and the inner frame 4 is also sealed.

[0021] Working principle: In this embodiment, the water-blocking plate 104 abutting against the side wall of the frame 204 can prevent a large amount of water from seeping in; the boss 202 and the first groove 103 are in close contact to further prevent water from seeping in; then, the sealing structure provided on both sides of the arc surface 102 not only prevents water from seeping in directly, but also prevents moisture from seeping in in a humid environment. At the same time, the chassis 1 in this embodiment is integrally molded, which can effectively play a waterproof role.

[0022] In one embodiment, the chassis 1, outer frame 2, and inner frame 4 have identical shapes. Both outer frame 2 and inner frame 4 are closed-loop structures, and the cross-sectional shape of the inner frame 4 is L-shaped. The outer frame 2, inner frame 4, and diffuser plate 5 are bonded together with adhesive. The L-shaped inner frame 4 increases the contact area with the diffuser plate 5 while reducing weight. Bonding the outer frame 2, inner frame 4, and diffuser plate 5 with adhesive, rather than using bolts or other methods, avoids the presence of holes that could allow moisture to seep in, thus improving the sealing effect.

[0023] In one embodiment, the chassis 1 is provided with reinforcing ribs, which can increase the structural strength of the chassis 1 itself.

[0024] In one embodiment, holes may be provided at the second groove 203 and the frame 204 to prevent water accumulation.

[0025] In one embodiment, the chassis 1 and the outer frame 2 can be fixed by means of clips, bolts, etc., but holes cannot be made in areas that affect the waterproofing effect, such as the inclined surface 101 and the arc surface 102 of the chassis. One feasible method is to provide a slot on the frame 204 and a clip on the baffle 104, and fix it by the clips and the slot. Alternatively, the first groove 103 can be fixed to the boss 202 by bolts, but in this case, waterproofing mainly relies on the sealing structure between the boss 202 and the inner frame 4.

[0026] In one embodiment, the sealing structure can be achieved by filling the area formed by the boss 202, the inner frame 4 and the diffuser plate 5 with sealant, then installing the chassis 1 so that the arc surface 102 of the chassis 1 penetrates into the sealant, and the sealing structure is formed after the sealant cures, achieving an IP65 sealing effect.
