[0028] The following is combined with Figure 1-8 The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0029] like Figure 1 and Figure 3 As shown, the present invention provides an LED panel light, including a lamp frame 1000, a light guide plate 200, a connecting portion 300 and a light bar 400. The light guide plate 200 is installed in the lamp frame 1000. The connecting portion 300 is used to connect the light guide plate 200 and the lamp frame 1000. There are generally four light bar 400, which are respectively installed on the inner wall of the lamp frame 1000 and opposite to the four side surfaces of the light guide plate 200.

[0030] like Figure 1 、 Figure 4 、 Figure 5 As shown, the lamp frame 1000 includes a bracket 1100 at the bottom. The bracket 1100 is a rectangular aluminum alloy frame surrounded by four side frames 1110. There is also a "mouth-shaped" channel 1120 in the middle. Specifically, the four side frames 1110 can be scattered and independent, and the connection between them can be achieved by fastener connection, welding, or bonding. More preferably, they are integrally formed and bent from a long strip of aluminum alloy. This is relatively strong and meets the aesthetic requirements of the lamp.

[0031] like Figure 3-Figure 5 As described above, each frame 1110 is provided with a first ridge 1111, a second ridge 1112, and a third ridge 1113 in sequence from the outer edge to the inner edge, and the extension direction of the ridges on each frame 1110 is consistent with its extension direction.

[0032] The light guide plate 200 is superimposed on the bracket 1100 , and the edge of the light guide plate 200 is outside the channel 1120 of the bracket 1100 , which can prevent the light guide plate 200 from falling from the channel 1120 . Preferably, the edge of the light guide plate 200 is flush with the edge of the bracket 1100 .

[0033] The connecting portion 300 plays two roles:

[0034] like Figure 2-Figure 5 As shown, on the one hand, the light guide strip can be fixed to the upper surface of the lamp frame 1000. Specifically, the connecting part 300 includes a first fixing plate 310, a second fixing plate 320, a third fixing plate 330, and a fourth fixing plate 340 that are independently separated, and each fixing plate is placed on the four edges of the light guide plate 200, and is respectively cooperated and connected with the four borders 1110 of the lamp frame 1000, so that the light guide plate 200 is clamped therebetween. The longitudinal cross-section shape of all the fixing plates is an isosceles trapezoid. When the light guide plate 200 is fixed, the four fixing plates enclose a rectangular frame of the same shape as the lamp frame 1000, and the two waistlines of each fixing plate are respectively aligned with one of the waistlines of the two adjacent fixing plates.

[0035] More specifically, Figure 3-Figure 5 As shown, the lamp frame 1000 also includes four retaining walls 1200 vertically connected to the four outer edges of the bracket 1100, respectively. Preferably, the retaining walls 1200 and the bracket 1100 are an integrally formed structure, and the sum of the height of the light guide plate 200 and the height of the bracket 1100 is less than or equal to the height of the retaining walls 1200, so that the light guide plate 200 is surrounded by the four retaining walls 1200 and is not easily detached from the lamp frame 1000.

[0036] like Figure 4 and Figure 5 As shown, the outer edge of the fixing plate is in contact with the top of the baffle 1200, the inner edge of the fixing plate is in contact with the top surface 210 of the light guide plate 200, the transverse cross-section of the fixing plate is an arc, the first ridge 1111 is in close contact with the baffle 1200, the second ridge 1112 and the first ridge 1111 are spaced a500 apart, and the third ridge 1113 and the second ridge 1112 are spaced b600 apart. The height of the first ridge 1111, the height of the second ridge 1112, the height of the third ridge 1113 and the height of the light guide plate 200 decrease in sequence, and the tops of the second ridge 1112 and the third ridge 1113 are both in contact with the bottom surface 220 of the fixing plate.

[0037] A through hole 311 is provided in the middle of the transverse cross-section of the fixing plate, and the through hole 311 is just above the spacing b600. A screw can be inserted into the through hole 311 and the spacing b600 and then tightened to connect the fixing plate to the lamp frame 1000. The fixing plate is provided with several through holes 311 at intervals in its extension direction, so that the longitudinal cross-section of each fixing plate is fitly connected to the longitudinal cross-section of each frame 1110 of the bracket 1100.

[0038] like Figure 4-Figure 6 As shown, specifically, optical bumps are provided on both the top and bottom surfaces of the light guide plate 200, so that the optical bumps on the upper and lower surfaces of the light bar 400 can reflect the light source provided by the light bar 400, thereby achieving the purpose of double-sided lighting. The optical bumps are punched out by a laser dot method, and the optical bumps are more rounded and uniform, thereby increasing the light reflection efficiency.

[0039] Secondly, the connecting portion 300 can be used to fix the entire LED panel light to the roof. Specifically, after the light guide plate 200 is clamped between the lamp frame 1000 and the connecting portion 300, Figure 7 and Figure 8 As shown, the intersection of two adjacent fixing plates of the connecting portion 300 can be detachably connected to a hanging portion 700. The hanging portion 700 includes a base 710 that is detachably connected to the fixing plates. A lifting ring is fixed to the base 710 for connecting a steel wire rope, the other end of which is fixed to the roof. By adopting the hanging installation method of the LED panel light, the top surface 210 of the light guide plate 200 is not in direct contact with the roof, so that the top surface 210 of the light guide plate 200 can still emit light.

[0040] Specifically, the light bar 400 is bonded to the side of the third ridge 1113 opposite to the side of the light guide plate 200, providing a light source for the entire LED panel light. Figure 2 and Figure 4 As shown, light bars 400 are only provided on the two longer frames 1110 of the bracket 1100 . Two light bars 400 are sufficient to provide light sources therefor, and the cost of installing four light bars 400 is also reduced.

[0041] like Figure 3-Figure 5 As shown, preferably, in order to prevent the bracket 1100 from wearing the light guide plate 200 and reducing the reflective efficiency of the light guide plate 200, the bottom surface 220 of the light guide plate 200 is not in direct contact with the bracket 1100, and a rubber anti-slip pad 800 is placed between each edge of the bottom surface 220 of the light guide plate 200 and the bracket 1100.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
