DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described below in conjunction with the embodiments and drawings.

[0032] like Figures 1 to 12 As shown,

[0033] A direct-down panel light, comprising:

[0034] The bottom box 1 is rectangular in shape, and the side of the bottom box 1 extends outward to form a pressing edge 12. A plurality of parallel LED light strips 11 are arranged on the inner side of the bottom of the bottom box 1. A plurality of LED lamp beads are arranged on the LED light strips 11. The LED lamp beads are provided with lenses, which are used to disperse the light emitted by the LED lamp beads and pass through the diffusion panel;

[0035] The top frame 3 is formed by connecting four side frames 31 end to end, the side frames include a pressing groove 311 and a pressing edge 312, the inner wall of the pressing groove 311 is symmetrically provided with a hook protrusion 313, the pressing groove is provided on the pressing edge, the free end of the pressing edge 312 is inclined toward the pressing groove, and the inner side of the pressing edge 312 is provided with a stop bar 314 parallel to the pressing groove;

[0036] The pressure strip 4 includes a bottom edge 41, a side edge 42 and a second inverted hook protrusion 43. The side edges are arranged parallel to each other and perpendicularly arranged on the bottom edge to form a slot 44. The slot 44 corresponds to the pressure slot. The second inverted hook protrusion is arranged on the outer wall of the free end of the side edge. The second inverted hook protrusion 43 is engaged with the first inverted hook protrusion. The pressure strip 4 is fixed to the top frame 3. One end of the bottom edge 41 is inclined toward the slot direction.

[0037] The diffusion panel 2 is fixedly mounted on a side of the bottom box 1 away from the LED light strip.

[0038] LED has the advantages of low power consumption, high luminous intensity, energy saving and environmental protection. Compared with traditional lamps such as incandescent lamps and fluorescent lamps, it is increasingly favored by users. However, the panel lights of the existing technology have the following defects: 1. Most of the panel lights are side-light structures, which will use the optical material of the light guide plate. The material of the light guide plate is PMMA or PS. The above materials will turn yellow and deteriorate after a period of use, which will affect the product quality and lighting effect; 2. The existing side-light panel lights are fixed with more than 30 screws, which is inefficient in the production and assembly process, and adds unnecessary costs. In addition, the splicing structure of the existing technology is difficult to assemble and has low efficiency.

[0039] To this end, the present invention designs a direct-down panel lamp, which eliminates the material of a light guide plate and uses a lens to disperse the light to achieve a uniform light output effect, while also avoiding the quality defects of traditional side-light panel lamps.

[0040] like Fig. 9 As shown, a plurality of LED lamp beads are arranged on the LED light strip 11, and a lens is arranged on the LED lamp beads, and the lens is used to disperse the light emitted by the LED lamp beads and pass the light through the diffusion panel; specifically, 7 parallel and equally spaced LED light strips 11 are arranged, and each LED light strip 11 is arranged with 8 LED lamp beads, and a lens is arranged on the LED lamp beads, and when the lens is working, the light emitted by the LED lamp beads is dispersed and passes through the diffusion panel 2, eliminating the light guide plate, so that the direct-down panel light will not turn yellow and deteriorate during use, and the lens disperses the light, so that the light output is uniform and the irradiation efficiency is high.

[0041] like Figure 5As shown, the top frame 3 is formed by connecting four side frames 31 end to end, and the pressure strip 4 and the top frame 3 are assembled by the cooperation of the pressing groove 311 and the card slot 44. Specifically, the second barb protrusion 43 and the first barb protrusion 313 are engaged with each other, so that the card slot 44 is inserted into the pressing groove 311. Compared with the splicing structure of the prior art, the engaging method of the pressing groove 311 and the card slot 44 of the present invention is simple to assemble and efficient.

[0042] like Fig.10 As shown, after assembly, since one end of the bottom edge 41 of the pressure strip 4 is inclined toward the slot 44, the inclined end of the bottom edge 41 contacts and presses the pressure edge 12 of the bottom box 1, and since the slot 44 cooperates with the pressure groove 311, the bottom box 1 is fixed. In the working process, since the bottom edge 41 is inclined toward the slot, there are two functions: 1. The bottom box 1 is fixed, and 2. The bottom edge 41 with the inclined free end makes the light irradiation avoid light leakage during the working process, and the use effect is good. Among them, after assembly, since the inner side of the pressure edge 312 is provided with a bar 314 parallel to the pressure groove, the bar 314 contacts the diffuser 2, and the free end of the pressure edge 312 is inclined toward the pressure groove, which further makes the fixing effect good, and can avoid light leakage when the light is irradiated, which is conducive to the divergence of light.

[0043] As a further improvement, the pressure strip 4 is further provided with a mounting groove 45, and the mounting groove 45 is detachably provided with a locking mechanism 5. The locking mechanism 5 is used as a safety hook to improve the safety of the direct-down panel light during installation.

[0044] As a further improvement, the locking mechanism 5 includes a base 52 and a hook 51, wherein the hook 51 is L-shaped, connected to the base 52 and inclined in a direction away from the base, and the angle between the base and the hook is a, satisfying the quantitative relationship: 130°≦a≦150°. The two ends of the base 52 are respectively provided with a first arm 521 and a second arm 522, wherein the first arm 521 is provided in a direction away from the hook 51 and is perpendicular to the base 52, one end of the first arm 521 is fixed to the base 52, and the other end of the first arm 521 is provided with a welt 5211, wherein the welt 5211 is connected to the first arm 521 and is parallel to the base 52. The second clamping arm 522 is arranged in a direction away from the clamping hook 51 and is perpendicular to the base 52. One end of the second clamping arm 522 is fixed to the base 52. The other end of the second clamping arm 522 extends outward to form a contact surface 5221. One end of the contact surface 5221 extends downward and tilts toward the inner side of the base 52.

[0045] like Figure 7 and 8As shown, during the specific installation, the locking mechanism 5 is fixed to the pressure strip 4 through the clamp arm 1 521 and the clamp arm 2 522. The pressure strip 4 is provided with a mounting groove 45. First, the clamp arm 1 521 is placed into the mounting groove 45, and then the clamp arm 2 522 is pressed into the mounting groove 45. Since the other end of the clamp arm 2 522 extends outward to form a contact surface 5221, one end of the contact surface 5221 extends downward and tilts toward the inner side of the base 52. The contact surface 5221 contacts the pressure strip 4, and the free end of the contact surface 5221 contacts the pressing edge 312. The fixing between the locking mechanism 5 and the direct-down panel light does not require the use of screws, and the assembly is simple.

[0046] As a further improvement, the second clamping arm 522 and the first clamping arm 521 are equal in length.

[0047] As a further improvement, a power box 6 is detachably provided on the pressure strip 4. The end structure of the power box 6 is similar to that of the locking mechanism 5, and is simple to assemble and easy to disassemble. More specifically, in order to prevent the power box from cracking or loosening during use, fixed ends 61 are symmetrically provided on both sides of the power box 6, and fixed holes are provided on the fixed ends 61. During assembly, the power box 4 and the bottom box 1 are fixed by screws, so that the power box 4 and the bottom box 1 will not crack or loosen during use.

[0048] As a further improvement, an arc groove 13 is provided between the pressing edge 12 and the bottom box 1. The arc surface of the arc groove 13 can contact the diffusion panel 2, and the bottom edge 41 is in contact with the pressing edge 12 of the bottom box 1. The above structure can prevent light leakage when light is irradiated, and the assembly structures are tightly connected, ensuring the quality of installation and good use effect.

[0049] The structure design of this direct-down panel light is reasonable. The light bar 11 is embedded in the inner side of the bottom box 1, and the diffuser plate 2 is installed at the same time to facilitate the uniform divergence of light and improve the illumination effect. The arrangement of the card slot and the pressure slot allows the second barb protrusion 43 and the first barb protrusion 313 to engage with each other, ensuring that the diffuser plate 2 is tightly connected with the top frame 3 and the pressure strip 4, ensuring the overall installation quality and good use effect. The assembly structure of this direct-down panel light does not require the use of bolts. Compared with the assembly structure of the prior art, the assembly efficiency is improved, the screwing process is eliminated, and the locking mechanism 5 can be directly inserted into the installation slot to achieve fast assembly and stable connection.

[0050] The preferred embodiments of the present invention are described herein, but the protection scope of the present invention is not limited thereto. Any modification or supplement or replacement of the specific embodiments described by those skilled in the art shall be included in the protection scope of the present invention.
