The circuit board is installed on the bottom wall of the lamp trough through the insulating sheet and is electrically connected to the lamp board. A connecting hole is provided on the insulating sheet, and the connecting hole is arranged corresponding to the mounting opening. The touch sheet is embedded in the mounting opening and is electrically connected to the circuit board through the connecting hole.

Specific embodiments

[0023] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described:

[0024] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0026] As Figures 1-5 shown in the intelligent eye protection table lamp with uniform light emission, including a lamp housing 10, a light source assembly, and a fixing ring 60. Specifically, the lamp housing 10 has a light-emitting surface, and the light-emitting surface is recessed to form a lamp groove. The light source assembly is installed in the lamp groove, and the fixing ring 60 covers the lamp groove; the light source assembly includes a lamp board 20, a reflective paper 30, a light-transmitting plate 40, and a prism plate 50. The lamp board 20 is arranged at the bottom of the lamp groove, and a plurality of light source modules 21 are arranged on the lamp board 20; the reflective paper 30 surrounds the inner side wall of the lamp groove, and the light-transmitting plate 40 and the prism plate 50 cover the lamp groove from the inside to the outside in sequence, and the light-transmitting plate 40 is used to guide the light emitted by the light source module 21 to be emitted; the prism plate 50 covers the side of the light-transmitting plate 40 away from the lamp board 20 and is used to guide the light emitted by the light-transmitting plate 40 to be emitted.

[0027] Based on the above structure, when using the intelligent eye-protecting desk lamp with uniform light emission of the present utility model, the lamp housing 10 can be connected to the base 110 through the support rod 100. One end of the support rod 100 is connected to the lamp housing 10, and the other end of the support rod 100 is connected to the base 110. In this way, the base 110 is placed on the tabletop for using the desk lamp. Specifically, the lamp board 20 can be assembled at the bottom of the lamp slot, and multiple light source modules 21 can be arranged on the lamp board 20. The working circuit of the lamp board 20 can be led out to the outside of the lamp slot through the power cord and conduct with the external mains electricity. Since the light generated by the multiple light source modules 21 arranged on the lamp board 20 diffuses around, the light is relatively scattered. The reflective paper 30 surrounding the bottom end of the lamp slot can reflect the generated light and guide the light to be concentrated, thereby improving the illumination intensity of the light.

[0028] It should be noted that the above reflective paper 30 is a reflective paper structure in the prior art and can be made of materials such as PET, PP, or PVC, with low production cost and good reflectivity.

[0029] In addition, since the light-transmitting plate 40 and the prism plate 50 cover the lamp slot from the inside to the outside in sequence, the light-transmitting plate 40 can use the PMMA light guide plate in the prior art to diffuse the light generated by the light source module 21 on the lamp board 20 from various angles, so that the linear light source of the light source module 21 is transformed into a surface light source, enabling the light to be evenly distributed after being led out by the light-transmitting plate 40, and the light irradiation is softer, avoiding the light being too concentrated to cause glare and thus affecting eyesight.

[0030] In addition, since the prism plate 50 covers the side of the light-transmitting plate 40 away from the lamp board 20, the light generated by the light emission of the light source module 21 reaches the prism plate 50 after being led out by the light-transmitting plate 40. The prism plate 50 can adopt the prism plate 50 structure in the prior art. A plurality of prism lenses can be uniformly arranged on the prism plate 50. For example, the shape of the prism lenses can be set into various shapes such as triangles, rhombuses, and polygons and are evenly spaced in the prism plate 50; in terms of the arrangement method, the plurality of prism lenses can also be spaced, arranged one-to-one, or other arrangement combinations are set, so that the prism lenses can make the light reflect and refract multiple times in the plate, thereby realizing the uniform diffusion of light. By precisely designing and optimizing the shape, angle, and arrangement method of the prism lenses, the prism plate 50 can evenly scatter the incident light in all directions, eliminating strong light spots and reflections, so that the light of the light source module 21 is more softly and evenly transmitted.

[0031] It should be noted that the light source module 21 can be selected as the LED strip structure in the prior art. Just assemble multiple LED strips on the lamp board 20, and the LED strips can be assembled on the lamp board 20 by means of bonding or screws, etc., which is convenient for disassembly, installation, and later maintenance.

[0032] Furthermore, a plurality of positioning blocks 11 protrude from the side wall of the above-mentioned lamp slot. The plurality of positioning blocks 11 are spaced apart along the circumferential direction of the lamp slot. In this way, the end faces of the plurality of positioning blocks 11 together form a positioning end face for supporting the lamp board 20. The lamp board 20 can be installed on the positioning end face. Exemplarily, the lamp board 20 can be installed on the positioning end face through a screw structure, or a buckle can be provided on the lamp board 20, and a bayonet can be provided on the positioning end face. The lamp board 20 is snapped onto the positioning end face by snapping the buckle into the bayonet, thereby forming a stable assembly structure, which also facilitates the disassembly, installation, maintenance of the lamp board 20 in the later stage. The positioning end face can support the end of the reflective paper 30, so that the end of the reflective paper 30 can abut against the positioning end face, avoiding the sliding and displacement of the reflective paper 30 during use.

[0033] Furthermore, the above-mentioned intelligent eye-protecting table lamp with uniform light emission further includes a circuit board 70, an insulating sheet 80, and a touch sheet 90. An installation opening 13 can be provided at the end of the lamp housing 10 facing away from the light-emitting surface. In this way, the circuit board 70 can be installed on the bottom wall of the lamp slot through the insulating sheet 80 and electrically connected to the lamp board 20, avoiding electric leakage of the circuit board 70 during use and conducting to the whole table lamp, resulting in electric shock to the human body, and improving the use safety. A connection hole 81 can be provided on the insulating sheet 80, and the connection hole 81 is correspondingly arranged with the installation opening 13. The touch sheet 90 is embedded in the installation opening 13 and electrically connected to the circuit board 70 through the connection hole 81. A touch switch can be provided on the circuit board 70. The touch switch can be an infrared sensor or a photoelectric switch in the prior art. In this way, when the human body touches the touch sheet 90, the infrared sensor or the photoelectric switch can be turned on or off, so that the touch sheet 90 can start or stop the touch switch during touching, enabling the circuit board 70 to supply power to start or stop the lamp board 20, and then controlling the turning on and off of the light source module 21 on the lamp board 20 to emit light.

[0034] It should be noted that the above-mentioned touch sheet 90 can be made of transparent materials such as glass, plastic, and crystal in the prior art.

[0035] Furthermore, the above-mentioned touch sheet 90 is made of acrylic material. The acrylic material has high transparency, so that when the human body touches the touch sheet 90, the infrared sensor or the photoelectric switch can more sensitively sense the change of light and perform corresponding start and stop. And the acrylic material has high strength, good wear resistance, and is not easy to break.

[0036] Furthermore, the lamp board 20 includes a circular substrate and a plurality of LED lights. The plurality of LED lights are distributed in a circular multi-layer and spaced apart on the substrate to form the above-mentioned light source module 21. In this way, the plurality of LED lights can be more evenly distributed on the circular substrate, so that the light emitted by the plurality of LED lights can be irradiated more evenly.

[0037] Further, the above-mentioned support rod 100 includes a plurality of support segments 101, and two adjacent support segments 101 are hinged to each other. Exemplarily, the support segments 101 can be set to two or three. Two adjacent support segments 101 can be connected in a hinged manner through a shaft structure in the prior art. Specifically, a swivel base can be installed at the end of one support segment 101, and a shaft can be installed at the end of the other support segment 101. In this way, the shaft can be rotatably installed on the swivel base to achieve the rotatable connection of two adjacent support segments 101, and a damping gasket structure in the prior art can be set in the shaft structure to increase the rotational damping between the two. In this way, when subjected to external human force, two adjacent support segments 101 can be adjusted and rotated in a limited manner, and when not adjusted manually, the damping force provided by the damping gasket makes the structure stable after the adjustment is in place.

[0038] When the support rod 100 is connected to the lamp housing 10, it can also be connected in a hinged manner through the above-mentioned shaft structure provided with a damping gasket. A connecting rod for connecting with the support rod 100 can be provided on the lamp housing 10. A shaft can be installed on the connecting rod, and then a swivel base can be installed at the end of one of the support segments 101. In this way, the shaft can be rotatably installed on the swivel base to achieve the rotatable connection between the lamp housing 10 and the support rod 100; and the other support segment 101 is connected to the base 110, so that the entire support rod 100 is connected to the base 110. In this way, the angle and position of the entire table lamp can be adjusted by applying external human force to the lamp housing 10, so as to meet the adjustment requirements of the user for the overall illumination angle and position of the table lamp in different usage scenarios.

[0039] Further, the lamp housing 10 is integrally cold forged from aluminum profiles, which enhances the overall structural strength of the table lamp, improves the heat dissipation performance inside the lamp housing 10, reduces the risk of overheating of the LED lamp caused by heat dissipation problems during use, and extends the overall service life of the table lamp.

[0040] Further, a limiting step 12 can be provided on the inner wall of the lamp housing 10, and a buckle can be provided on the fixing ring 60. In this way, the fixing ring 60 can be connected to the lamp housing 10 by snapping the buckle onto the limiting step 12, which improves the assembly efficiency of the fixing ring 60 and facilitates disassembly, installation and maintenance in the later stage.

[0041] For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the present utility model.
