DETAILED DESCRIPTION

[0029] 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.

[0030] Example

[0031] In this embodiment, directional terms such as top surface and bottom surface are only used for convenience of description and are not intended to limit the invention.

[0032] See Figures 1 to 4 As shown, an embedded three-proof frameless flat panel light includes a chassis 1, a plurality of light source strips 2, a light source driving board 3 and a light-transmitting panel 4. The bottom surface of the chassis is provided with a light source cavity 5 with a small top and a large bottom. In this embodiment, the chassis is a plastic chassis, and the edge of the chassis is provided with an embedded mounting wheel bone buckle 12. The chassis is square or round. In this embodiment, the light source strips all adopt a lens refraction process, which can not only save costs and improve the convenience of assembly, thereby facilitating production efficiency and reducing production costs, but also the light source strips and the light source driving board are all sealed in the light source cavity, which can improve the three-proof effect of waterproof, dustproof and moisture-proof, and has strong practicality.

[0033] The number of the light source strips is four. The side wall of the light source cavity is set at an angle of 130 degrees to 150 degrees to the top wall of the light source cavity. In actual application, the length of the light source strip matches the width of the top wall of the light source cavity; during assembly, the two end edges of the light source strip are respectively attached to the side walls of the light source cavity. The above structure can improve the stability of the installation of the light source board. During assembly, the refractive lenses around the light source strip are tightly attached to the outermost edge of the light source cavity, and the closest point to the inclined plane angle of 130 degrees to 150 degrees of the light source cavity is the origin of the light source distribution of the entire lamp, and then the light is evenly distributed on the basis of the origin, which can make the light-emitting surface uniform and without light spots, and at the same time, the light is reflected to the outermost edge of the light source cavity at the maximum angle, so that while achieving a borderless state, the light distribution effect is good and uniform without light spots, ensuring the consistency of the light-emitting surface. Then reversely determine the fixing hole positions of the light source bar and the light source driver board and the center point position of the snap bosses that fix the light source board in the light source cavity. The distribution of the snap bosses is obtained by extending the geometric dimensions of the light distribution effect. After these snap circular holes are determined, the plastic snap bosses are melted and riveted to the light source bar and the light source driver board through a hot melt process, thereby replacing the gluing process. This can save materials, while also ensuring firmness and making operation and installation more convenient.

[0034] The large angle makes the refraction or reflection angle of the light from the light source cavity larger, and the light can be diffused to the maximum edge of the lamp, ensuring the uniformity of the entire luminous surface, and the luminous area reaches 99.99%, which is more than 20% higher than the traditional flat lamp. In actual application, after the lamp beads on the light source board refract and emit light through the lens at 150-170 degrees, the chassis light guide angle is 130-150 degrees, which is close to the angle of the lens, and can more conveniently guide the light to the edge of the lamp to obtain a larger luminous area. At the same time, the angle will not block the light to form a shadow, so that the luminous surface of the entire lamp is uniform, and the edge of the lamp emits light without shadow, achieving a frameless effect and three-proof effect, and is highly practical.

[0035] At the same time, in the actual application process, the top edge of the light source cavity is provided with a connection hole 6, and the top edge of the chassis is provided with a wire slot 10, and the connection hole is at one end of the wire slot; a plurality of buckle bosses 7 are provided on the top wall of the light source cavity; buckle round holes 8 are provided on the light source bar and the light source driving board; during assembly, the light source bar and the light source driving board are buckled with the buckle round holes through the buckle bosses and hot-melt the buckle bosses for positioning; at the same time, the light source bar is electrically connected to the output end of the light source driving board, and the input end wire of the light source driving board passes through the connection hole and extends out of the chassis, and the input end wire is bent and positioned in the wire slot and sealed by the glue layer in the wire slot. Through the above structure, the sealing of the bonding point between the input end wire and the chassis can be improved, which is conducive to improving the waterproof, dustproof and moisture-proof performance, and has strong practicality, and the buckle bosses cooperate with the buckle round holes to realize the positioning of the light source bar and the light source driving board, improve the convenience of disassembly and assembly, and have strong practicality.

[0036] In actual application, an L-shaped table top 11 is provided at the edge of the light source cavity, and a U-shaped groove 9 is provided on the horizontal edge of the L-shaped table top; the edge of the light-transmitting panel is attached to the L-shaped table top and the light-transmitting panel is sealed and fixed in the U-shaped groove. The vertical side height of the L-shaped table top is 0.8-1.5mm, and the thickness is 0.5-1.0mm; the total horizontal side width of the L-shaped table top is 1.0-2.0mm, and the radius of the U-shaped groove is 0.25-0.5mm. In this embodiment, the width of the L-shaped table top of the light-transmitting panel is preferably 1.0-2.0mm, which can not only hold the minimum load-bearing and pressure-bearing area of ​​the light-transmitting panel, but also avoid blocking light to form a luminous area without dark areas, so that the light can be refracted to the very edge of the lamp to achieve a borderless effect;

[0037] The optimal height of the L-shaped table top is 0.8-1.5mm, and the thickness is 0.5-1.0mm. The thickness can prevent the light-emitting surface of the lamp from being concave in the middle, and will not increase the processing cost. It can ensure the gluing process and ultrasonic welding process requirements of the light-transmitting panel and the lamp cavity, and at the same time realize the borderless process of the largest size, ensuring 99.99% of the light-emitting surface.

[0038] The edge of the light-transmitting panel is attached to the U-shaped groove and sealed and fixed by the glue-filled adhesive layer in the U-shaped groove. Alternatively, the edge of the light-transmitting panel is attached to the U-shaped groove and fixed by ultrasonic welding. The sealing by the glue-filled adhesive layer or the ultrasonic welding can ensure the sealing of the bonding point, and the sealing of the bonding point of the input end wire can be combined to improve the sealing of the overall lamp, which has strong applicability and good practicality.

[0039] The utility model has positive effects: the structure of the utility model is reasonably arranged, and a connecting hole connected with the light source cavity is provided on the chassis, and a wire groove is provided at the edge of the top surface of the chassis. The wires of the light source driving board are bent in the wire groove and sealed by the glue filling layer, thereby ensuring the sealing of the wire bonding point, and effectively preventing water, dust and the like from entering from the wire connection point, thereby improving the waterproof, dustproof and moisture-proof performance, and having strong practicality. In addition, there is a U-shaped groove at the edge of the light source cavity, and the edge of the light-transmitting panel is attached to the U-shaped groove and sealed and fixed, and cooperates with the sealing at the wire, thereby ensuring the sealing and waterproof performance of the overall lamp, and the use is stable and reliable, and the applicability is strong and the practicality is good.

[0040] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. 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. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
