DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0031] See Figures 1 to 4 As shown, a bidirectional LED flat panel light comprises a lamp frame 2 and a back cover 3 fixed by screws 1, and a lamp cavity 4 is arranged on the bottom surface of the back cover; in actual application, the back cover is a hardware back cover. The lamp frame is an injection molded ABS structure. And the back cover is a circular, oval or square back cover. In this embodiment, the back cover is circular.

[0032] At the same time, in this embodiment, a side light source panel 5 is fixed on the inner wall of the lamp cavity; the lamp cavity is provided with a reflective film 6, a light guide plate 7 and a diffuser plate 8 in sequence from top to bottom; the lamp beads of the side light source panel are located on the side of the light guide plate; its side light source panel is a conventional structure of the prior art, and can be a light strip or a conventional structure such as a light bar, and its light passes through the light guide plate, is reflected by the reflective film, and irradiates downward from the diffuser plate.

[0033] At the same time, in this embodiment, a light-transmitting ring 9 is also provided between the lamp frame and the back cover; the light-transmitting ring is a light-transmitting injection-molded PS structure. The inner top surface of the light-transmitting ring is attached to the bottom edge of the diffuser plate, and the outer side surface of the light-transmitting ring extends out of the outer frame edge of the lamp frame; the light from the edge of the diffuser plate will irradiate the light-transmitting ring, and irradiate from the side of the lamp frame through the outer side surface of the light-transmitting ring, thereby achieving two-way irradiation, which is beneficial to improving the lighting effect. When in use, the light from the side light source plate irradiates downward through the light guide plate and the diffuser plate, and at the same time, the light from the side light source plate irradiates outward from the side of the lamp frame through the light-transmitting ring.

[0034] In actual application, the inner frame edge top surface of the lamp frame is integrally formed with a limiting convex ring 10, and the top surface of the lamp frame is fixed with limiting screw hole columns 11 at equal intervals; during installation, the bottom surface of the diffuser plate is attached to the limiting convex ring, and the top surface of the limiting screw hole column is attached to the edge of the back cover, and the screw passes through the back cover and is threadedly fixed with the limiting screw hole column. The limiting convex ring mainly ensures that there is a distance between the diffuser plate and the top surface of the lamp frame so that the light-transmitting plate can be installed.

[0035] At the same time, in actual application, a stepped convex ring 12 is integrally formed at the inner ring edge of the top surface of the light-transmitting ring; a C-shaped avoidance groove 13 is provided at the inner ring edge of the light-transmitting ring; during installation, the inner ring edge of the light-transmitting ring is attached to the outer surface of the limiting convex ring, and the limiting screw hole column is in the C-shaped avoidance groove; and the top surface of the stepped convex ring abuts against the bottom edge of the diffuser plate. Through the stepped convex ring, it can not only be attached to the bottom edge of the diffuser plate, but also allow the light of the side light source plate to irradiate the side of the stepped convex ring, which can improve the side irradiation effectiveness of the light-transmitting ring.

[0036] In actual application, an EPE board 14 is arranged between the top surface of the reflective film and the top wall of the lamp cavity. The EPE board is a conventional structure of the prior art and is simply applied.

[0037] The utility model has positive effects: the structure of the utility model is reasonably arranged, and it is not only provided with a light guide plate cooperating with a diffusion plate, so that the light from the side light source plate can be irradiated downward through the light guide plate, but also provided with a light-transmitting ring, and the outer side surface of the light-transmitting ring extends out of the outer frame edge of the lamp frame, so that the light at the edge of the diffusion plate can be irradiated outward from the outer frame edge of the lamp frame through the light-transmitting ring, thereby realizing two-way light irradiation from the bottom and sides, which is beneficial to improving the lighting decoration effect, and it is convenient to disassemble and assemble, stable and reliable to use, and has strong applicability and good practicality.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
