Detailed Description

Referring to FIG. 1, FIG. 1 shows a cross-sectional view of a panel light fixture. A new structure LED panel lamp comprises a frame 1, a face cover 2, a chassis 3 and a crimping screw 4; in addition, the panel lamp further includes an LED light bar and a driving power supply device (both not shown), and the LED light bar and the driving power supply are disposed at the chassis 3.

The frame 1 is integrally in a strip shape or a ring shape, and can be determined according to different lamp types, such as a rectangular panel lamp, and the frame 1 is in a strip shape; in the case of a circular panel light, the frame 1 is circular in shape. The frame 1 is of an aluminum profile structure and is formed through the extrusion process or the forging and casting process. The bottom of the frame 1 is provided with a support plate 11, the support plate 11 is planar, a bulge 12 is arranged at the right side position of the support plate 11, the bulge direction of the bulge 12 is towards the inner side direction of the support plate, namely the upward side direction, and the support plate and the bulge are combined to form an L-shaped structure part; the frame 1 is further provided with a screw twisting part 13 which is connected with the edge of the support plate 11 and has a hollow structure, and specifically, the screw twisting part 13 is a U-shaped groove body.

Further, in some embodiments, as shown in fig. 3, a groove 131 is provided at an inner side wall of the U-shaped groove of the screw twisted portion 13 along an extending direction of the groove, a groove opening faces the inner side of the U-shaped groove, and the grooves 131 at the two side walls are oppositely arranged in a paired manner. Crimping screw 4 that adopts at actual assembly panel lamps and lanterns in-process often is self tapping type screw, and the purpose that sets up recess 131 reduces crimping screw 4 to the extrusion force of U type cell body both sides wall when crimping screw 4 screws in screw transposition portion 13, thereby often can lead to the both sides wall of U type cell body to produce the bursting apart or deformation and cause the screw transposition effect inefficacy problem if the extrusion force is too big.

The surface cover 2 is a planar light emitting and diffusing plate made of PMMA material, the surface cover 2 is of a thin structure, and the end parts of two sides of the surface cover 2 can abut against the protruding part 12.

The chassis 3 is a structural body formed by punching and molding thin sheet metal materials, and the position of the structural body is a concave structure and used for placing an LED light bar; pressing parts 31 are arranged at the end parts of two sides of the chassis 3, the pressing parts 31 are structural parts bent and protruded downwards at the end parts of the chassis 3, the positions of the pressing parts 31 correspond to the positions of the supporting plates 11 of the frame 1, the chassis 3 is also provided with fixing holes 32 at the outer side positions of the pressing parts, and the positions of the fixing holes 32 correspond to the positions of the screw twisting parts 13.

As shown in fig. 1 and 2, the pressing screw 4 is used to pass through the fixing hole 32 on both sides of the chassis 3 and lock in the screw hinge 13, thereby achieving the fixed connection of the chassis 3 and the frame 1. In the initial state, two ends of the surface cover 2 abut against the top ends of the convex parts 12 at the two ends, and the surface cover 2 is in a planar state; when the crimping screw 4 is locked at the screw twisting part 13, the pressing part 31 in the chassis 3 presses the face cover 2 from top to bottom, and the end part of the face cover 2 is supported by the convex part 12, so that the middle part of the face cover 2 can be deformed towards the lower side by taking the convex part 12 as a supporting point, and the maximum deformation is that the face cover 2 is pressed downwards by the pressing part 31 to abut against the edge side position of the supporting plate 11. As shown in fig. 2, in the assembled panel lamp, the entire surface cover 2 has a micro-arc surface modeling structure bent toward one side.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is specific and detailed, but cannot be understood as the limitation of the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
