DETAILED DESCRIPTION

[0025] Below, the present invention is further described with reference to the accompanying drawings and specific embodiments:

[0026] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figures 1-6 The illustrated embodiment of a high-heat dissipation intelligent eye-protection desk lamp includes a lamp holder 10, a lamp post 20, and a position-limiting rotation mechanism 30. The position-limiting rotation mechanism 30 includes a position-limiting frame 33, a connecting shaft 31, and a position-limiting plate 32. The position-limiting frame 33 is fixed to the lamp holder 10, and one end of the connecting shaft 31 is connected to the top of the lamp post 20. The other end of the connecting shaft 31 can rotatably pass through the position-limiting frame 33. The position-limiting plate 32 is provided on the connecting shaft 31, and a position-limiting block 331 is provided on the position-limiting frame 33. The position-limiting block 331 can abut against the position-limiting plate 32 when the lamp holder 10 rotates.

[0029] On the basis of the above structure, the high-heat dissipation intelligent eye-protection desk lamp of the present invention is used. When the lamp head 10 is rotated, the rotation of the lamp head 10 can drive the limit frame 33 connected thereto to rotate relative to the connecting shaft 31, and the connecting shaft 31 is fixedly connected to the lamp pole 20. Therefore, when the lamp head 10 is rotated, it can be rotated with the connecting shaft 31 as the axis of rotation to adjust the lighting angle of the lamp head 10. The limit frame 33 is provided with a limit block 331, and the connecting shaft 31 is provided with a limit plate 32. Therefore, when the lamp head 10 is rotated, the limit block 331 on the limit frame 33 abuts against the limit plate 32 on the connecting shaft 31, which can limit the rotation angle of the lamp head 10. Therefore, the adjustment angle of the lamp head 10 can be limited, preventing the internal wire of the lamp head 10 from breaking or desoldering due to excessive rotation angle. The overall structure is stable and reliable.

[0030] Furthermore, the limiting rotation mechanism 30 in this embodiment also includes a connecting head 34. When the above-mentioned connecting shaft 31 is assembled with the lamp holder 10, the connecting shaft 31 can be rotatably passed through the limiting frame 33 and then threaded into the connecting head 34. In this way, the limiting plate 32 is clamped between the connecting head 34 and the limiting frame 33. Due to the setting of the connecting head 34, the connecting shaft 31 and the limiting frame 33 can be prevented from being separated, and the assembly structure is stable.

[0031] Furthermore, a plug-in block can be provided on the connecting shaft 31, and a connecting rod 23 is provided corresponding to the top of the lamp pole 20. One end of the connecting shaft 31 is inserted into the connecting rod 23 with the plug-in block to realize the connection between the connecting shaft 31 and the lamp pole 20. The outer surface of the plug-in block is a flat surface, and an insertion groove is provided in the connecting rod 23. After being inserted into place, the flat surface is used to realize limiting to prevent relative rotation between the connecting shaft 31 and the connecting rod 23 of the lamp pole 20.

[0032] In the case of an insertion block, after one end of the connecting shaft 31 is inserted into the connecting rod 23 of the lamp pole 20 through the insertion block, the other end of the connecting shaft 31 passes through the limit frame 33 and is threadedly connected to the connecting head 34, so that the limit frame 33 can be clamped between the limit plate 32 and the insertion block, that is, the limit plate 32 and the limit frame 33 are both tightly assembled, increasing the rotational damping and preventing the lamp head 10 from rotating and falling under its own gravity.

[0033] Furthermore, a damping plate 35 can be sandwiched between the connector 34 and the stopper 32. This also increases the damping force between the connector 34, the stopper, and the stopper 32, preventing the lamp holder 10 from rotating and falling under its own weight, thereby effectively ensuring the stability of the connection between the lamp body and the lamp arm. Furthermore, the connector 34 can be a nut head as known in the art.

[0034] Furthermore, to facilitate assembly of the limiting frame 33 with the lamp holder 10, the limiting frame 33 includes a first connecting piece 332 and two second connecting pieces 333. The two second connecting pieces 333 are connected to both sides of the bottom end of the first connecting piece 332. The two second connecting pieces 333 can be formed by bending outward from both sides of the bottom end of the first connecting piece 332. Screw holes are provided on the second connecting pieces 333. In this way, the two second connecting pieces 333 are connected to the lamp holder 10 via screws. The two second connecting pieces 333 are connected to the lamp holder 10 on both sides, and the assembly structure is stable. The connecting shaft 31 can be rotatably passed through the first connecting piece 332 and connected to the connector 34.

[0035] Furthermore, the lamp holder 10 includes a lamp housing 12 and a light source mechanism. The lamp housing 12 is provided with an installation cavity 121 and a light outlet. A plurality of heat dissipation ribs 122 are provided in the installation cavity 121. The plurality of heat dissipation ribs 122 are spaced apart in the length direction of the installation cavity 121. The heat dissipation ribs 122 include a first heat dissipation rib 122 section and two second heat dissipation rib 122 sections. The first heat dissipation rib 122 section is provided on the end wall of the installation cavity 121. The two second heat dissipation rib 122 sections are connected to both sides of the first heat dissipation rib 122 section and extend to the side wall of the installation cavity 121. The limiting frame 33 is connected to the lamp housing 12. A light source mechanism is provided in the installation cavity 121.

[0036] Furthermore, the lamp holder 10 also includes a heat sink 13, which is installed in the installation cavity 121 and abuts against the first heat sink 122 section of a plurality of heat sink ribs 122; both sides of the heat sink 13 abut against the second heat sink 122 section; the light source mechanism includes a lamp board 14, a light-transmitting member and a lamp cover 16, the lamp board 14 is detachably arranged on the heat sink 13, and a plurality of lamp beads are arranged on the lamp board 14; the light-transmitting member covers the lamp board 14 and guides the light of the lamp beads to be output; the lamp cover 16 is detachably covered on the light outlet so as to cover the outside of the light-transmitting mechanism.

[0037] Specifically, during assembly, the heat sink 13 can be first assembled to the mounting cavity 121 of the lamp housing 12 by means of screws or bolts, and then the lamp board 14 and the light-transmitting member of the light source assembly are assembled in sequence from the inside to the outside, and then the light outlet of the mounting cavity 121 is sealed with the lamp cover 16. Since a number of lamp beads are arranged on the lamp board 14, the lamp beads can be electrically connected to the external power supply circuit through the lamp board 14 to generate lighting light, and the light-transmitting member is sealed on the lamp board 14 to guide the light generated by the lamp beads to be guided out through the light-transmitting member, and then the lamp cover 16 is sealed to the light outlet position. In this way, the light generated by the lamp beads on the lamp board 14 is soft and uniform with the light guided by the light-transmitting member, which has an eye protection effect. Moreover, when the lamp is used for lighting, the heat generated by the lamp beads can be directly conducted to the heat sink 13 through the lamp board 14 for dissipation, so that the heat generated by the lamp beads can be timely dissipated when the lamp is used for lighting.

[0038] It should be noted that the light panel 14 is detachably mounted on the heat sink 13, which can be achieved by means of conventional buckle 161 structures and screw connections. For example, a buckle 161 can be provided on the light panel 14, while a slot 123 can be provided on the heat sink 13. The buckle 161 can be engaged with the slot 123 to connect the light panel 14 to the heat sink 13, facilitating subsequent assembly and disassembly for maintenance. The lamp cover 16 is detachably sealed to the light outlet, and can also be connected by means of conventional screws, bolts, and other structures, making assembly and disassembly easier and facilitating subsequent maintenance.

[0039] In addition, a plurality of heat dissipation ribs 122 may be provided in the installation cavity 121, and the plurality of heat dissipation ribs 122 may be spaced apart in the length direction of the installation cavity 121, and the heat dissipation ribs 122 include a first heat dissipation rib 122 section and two second heat dissipation rib 122 sections, and the first heat dissipation rib 122 section may be provided on the end wall of the installation cavity 121; and the two second heat dissipation rib 122 sections are connected to both sides of the first heat dissipation rib 122 section and extend to the side wall of the installation cavity 121, and then the above-mentioned heat dissipation fin 13 may be installed at the bottom end of the installation cavity 121 and abut against the first heat dissipation rib 122 section of the plurality of heat dissipation ribs 122; and the two sides of the heat dissipation fin 13 abut against the second heat dissipation rib 122 sections. With such an arrangement, when the lamp is used for lighting, the heat generated by the lamp beads can be conducted to the plurality of heat dissipation ribs 122 through the heat sink 13, and then the heat is evenly conducted to the lamp housing 12 through the first heat dissipation rib 122 section and the second heat dissipation rib 122 section, and then the heat is conducted to the external space for heat dissipation, thereby avoiding uneven heat conduction inside the lamp causing damage due to excessive local heat, thereby improving the overall heat dissipation and heat conduction efficiency of the lamp.

[0040] Furthermore, the above-mentioned light source mechanism also includes a fixed frame, and two light-transmitting openings can be set on the fixed frame, and the two light-transmitting openings are spaced apart in the length direction of the installation cavity 121; and there are two light-transmitting parts, and the two light-transmitting parts can be sealed on the light-transmitting openings one by one; in this way, when used for lighting, the light source generated by the lamp beads on the lamp board 14 is guided by the light-transmitting parts on the two light-transmitting openings to form two spaced light sources, which is equivalent to forming two lighting areas, so that the light can be more evenly irradiated to the work surface, reducing the shadows and ghosting in the irradiated area of ​​the work surface, and then the lamp cover 16 is sealed on the outside of the fixed frame to prevent the fixed frame from shifting or slipping during use.

[0041] In addition, after using a fixing frame to assemble the two light-transmitting parts, the fixing frame and the lamp board 14 are assembled to the heat sink 13 in sequence to form a modular light source mechanism, which is then connected to the lamp cover 16 with screws and other connecting parts, and then the lamp cover 16 is buckled into the mounting cavity 121 of the lamp housing 12 in an upside-down manner, which makes assembly convenient.

[0042] Furthermore, the light-transmitting part includes a light-transmitting plate 15 and a light-diffusing plate 11, which are sequentially covered from the inside to the outside. The light-transmitting plate 15 can adopt the PMMA light guide plate in the prior art to diffuse the light generated by the lamp beads on the lamp board 14 from all angles, thereby converting the linear light source of the lamp beads into a surface light source. In this way, the light is evenly distributed after being guided out through the light-transmitting plate 15, and the light illumination is softer, avoiding excessive concentration of light to cause glare and thus affect vision.

[0043] The diffuser 11 can adopt the prism plate structure in the existing technology, and a plurality of prism sheets can be evenly arranged on the prism plate, so that the light emitted by the light source on the lamp board 14 can pass through the light-transmitting plate 15, and then the diffuser 11 formed by the plurality of prism chip structures refracts and reflects the light to achieve uniform light. The light is not dazzling, anti-fatigue, and has a strong eye protection effect.

[0044] Furthermore, a number of clips 161 can be set on the lamp cover 16, and a number of slots 123 can be set on the inner side of the light outlet. The above-mentioned clips 161 are connected to the above-mentioned slots 123 one by one. In this way, the lamp cover 16 can be connected to the light outlet to cover the light outlet, making the overall structure of the lamp more solid, and also convenient for later disassembly and maintenance.

[0045] Furthermore, the lamp pole 20 includes a plurality of mutually hinged lamp pole sections 21, and the connecting shaft 31 is connected to one of the lamp pole sections 21. On the basis of the structure provided with a connecting rod 23, the connecting shaft can be set on one of the lamp pole sections 21, so that the lamp head 10 is connected to the connecting rod 23 of the lamp pole section 21 through the connecting shaft 31. The lamp head 10 and the lamp pole section 21 of the lamp pole 20 can be rotated to realize the rotation angle adjustment of the lamp head 10 and the lamp pole 20, and the lamp pole sections 21 and the lamp pole sections 21 can be rotated with each other, so that the angle of the lamp pole 20 itself can be adjusted. By adjusting the angle of the lamp pole 20 itself and coordinating the angle adjustment of the lamp head 10 and the lamp pole section 21, the lighting angle of the lamp head 10 can be adjusted in a wider range.

[0046] Of course, the rotatable connection between the lamp pole segments 21 can be achieved by hinged connection via a swivel base and a rotating shaft, and the rotating shaft can be rotatably engaged via a damping washer or bolt structure. In this way, the rotation between the lamp pole segments 21 requires the use of an external force to overcome the damping force for rotational adjustment, thereby preventing the lamp pole segments 21 from rotating under their own weight. In addition, a lamp holder 22 can be provided at the bottom end of the lowest lamp pole segment 21 to support the entire lamp pole 20.

[0047] Those skilled in the art can make various other corresponding changes and deformations based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the present utility model.
