Therefore, they cannot be understood as limitations on the present invention.

[0025] 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.

[0026] like Figure 1 、 Figure 2 as well as Figure 3 The heat dissipation lamp head assembly of the intelligent eye protection desk lamp shown in the figure includes a lamp housing 10, a heat sink 20 and a light source mechanism.

[0027] Specifically, the lamp housing 10 is provided with a mounting cavity 11 and a light outlet. The mounting cavity 11 is provided inside the lamp housing 10, and the light outlet is provided at the bottom end of the lamp housing 10, and the light outlet and the mounting cavity 11 are connected. A plurality of heat dissipation ribs 12 are provided in the mounting cavity 11, and the plurality of heat dissipation ribs 12 are spaced apart along the length direction of the mounting cavity 11. The heat dissipation ribs 12 include a first heat dissipation rib 12 segment and two second heat dissipation rib 12 segments. The first heat dissipation rib 12 segment is provided on the end wall of the mounting cavity 11. The two second heat dissipation ribs 12 segments are connected to both sides of the first heat dissipation rib 12 segment and extend to the side walls of the mounting cavity 11.

[0028] In addition, the heat sink 20 can be installed at the bottom of the installation cavity 11 and abut against the first heat sink rib 12 of the plurality of heat sink ribs 12; and both sides of the heat sink 20 abut against the second heat sink rib 12;

[0029] In addition, the light source mechanism can be installed in the mounting cavity 11 through the light outlet. The light source mechanism includes a lamp board 31, a light-transmitting member and a lamp cover 34. The lamp board 31 is detachably arranged on the heat sink 20. A plurality of lamp beads are arranged on the lamp board 31. The light-transmitting member is sealed on the lamp board 31 and guides the light of the lamp beads to be output. The lamp cover 34 is detachably sealed on the light outlet to cover the outside of the light-transmitting member.

[0030] On the basis of the above structure, the heat dissipation lamp head assembly of the intelligent eye protection desk lamp of the present invention is used. The above lamp head assembly can be connected to the base through a support rod, and the base is placed on the table for use as a desk lamp. During assembly, the heat sink 20 can be first assembled to the installation cavity 11 of the lamp housing 10 through screws or bolts and other structures, and then the lamp board 31 and the light-transmitting member of the light source assembly are assembled from the inside to the outside in sequence, and then the light outlet position of the installation cavity 11 is covered with a lamp cover 34. Since a number of lamp beads are arranged on the lamp board 31, the lamp beads can be electrically connected to the external power supply circuit through the lamp board 31 to generate lighting light, and the light-transmitting member is covered on the lamp board 31 to guide the light generated by the lamp beads to be output through the light-transmitting member, and then the lamp cover 34 is covered to the light outlet position, so that the light generated by the lamp beads on the lamp board 31 is soft and uniform with the light guided by the light-transmitting member, which has an eye protection effect. When the lamp is used for lighting, the heat generated by the lamp beads can be directly transferred to the heat sink 20 through the lamp board 31 for heat dissipation, so that when the lamp is used for lighting, the heat generated by the lamp beads can be timely dissipated by heat conduction.

[0031] It should be noted that the light panel 31 is detachably mounted on the heat sink 20, which can be achieved by means of conventional buckle 341 structures and screw connections. For example, a buckle 341 can be provided on the light panel 31, while a slot 13 can be provided on the heat sink 20. The buckle 341 can be engaged with the slot 13 to connect the light panel 31 to the heat sink 20, facilitating subsequent assembly and disassembly for maintenance. The lamp cover 34 is detachably mounted on the light outlet, and can also be connected using conventional screws, bolts, and other structures. This makes assembly and disassembly easier and facilitates subsequent maintenance.

[0032] In addition, a plurality of heat dissipation ribs 12 may be provided within the mounting cavity 11, and the plurality of heat dissipation ribs 12 may be spaced apart along the length of the mounting cavity 11. The heat dissipation ribs 12 include a first heat dissipation rib 12 segment and two second heat dissipation rib 12 segments. The first heat dissipation rib 12 segment may be provided on the end wall of the mounting cavity 11; the two second heat dissipation rib 12 segments are connected to both sides of the first heat dissipation rib 12 segment and extend to the side walls of the mounting cavity 11. The heat sink 20 may then be installed at the bottom end of the mounting cavity 11 and abut against the first heat dissipation rib 12 segment of the plurality of heat dissipation ribs 12; and both sides of the heat dissipation rib 20 abut against the second heat dissipation rib 12 segments. With this arrangement, when the lamp is in use, heat generated by the lamp beads can be conducted through the heat sink 20 to the plurality of heat dissipation ribs 12, and then evenly conducted to the lamp housing 10 through the first heat dissipation rib 12 segment and the second heat dissipation rib 12 segment, and then conducted to the external space for dissipation, thereby avoiding damage caused by uneven heat conduction within the lamp resulting from excessive local heat, thereby improving the overall heat dissipation and heat conduction efficiency of the lamp.

[0033] Furthermore, a bending section can be provided on both sides of the heat sink 20, and the bending section can be placed against the inner side of the second heat dissipation rib 12. This arrangement increases the heat dissipation area of the heat sink 20. When used for lighting, the heat generated by the lamp beads can be conducted to the second heat dissipation rib 12 through the bending section and then further conducted to the lamp housing 10 and then dissipated to the external space, which can further improve the overall heat dissipation and thermal conductivity efficiency of the lamp.

[0034] Furthermore, the above-mentioned light source mechanism also includes a fixed frame 35, and two light-transmitting openings 351 can be set on the fixed frame 35, and the two light-transmitting openings 351 are spaced apart in the length direction of the installation cavity 11; and there are two light-transmitting parts, and the two light-transmitting parts can be sealed on the light-transmitting openings 351 one by one; in this way, when used for lighting, the light source generated by the lamp beads on the lamp board 31 is guided by the light-transmitting parts on the two light-transmitting openings 351 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 double images in the irradiated area of the work surface, and then the lamp cover 34 is sealed on the outside of the fixed frame 35 to prevent the fixed frame 35 from shifting or slipping during use.

[0035] In addition, after the two light-transmitting parts are assembled using the fixing frame 35, the fixing frame 35 and the lamp panel 31 are assembled to the heat sink 20 in sequence to form a modular light source mechanism. After that, they are connected to the lamp cover 34 with screws and other connecting parts, and then the lamp cover 34 is buckled into the mounting cavity 11 of the lamp housing 10 in an inverted manner, which makes assembly convenient.

[0036] Furthermore, the light-transmitting part includes a light-transmitting plate 32 and a light-scattering plate 33, which are sequentially covered from the inside to the outside; the light-transmitting plate 32 can adopt the PMMA light guide plate in the prior art to diffuse the light generated by the lamp beads on the lamp board 31 from all angles, thereby converting the linear light source of the lamp beads into a surface light source, so that the light is evenly distributed after being guided out through the light-transmitting plate 32, and the light illumination is softer, avoiding excessive concentration of light to cause glare and thus affect vision.

[0037] The diffuser 33 can adopt the prism plate structure in the existing technology, and multiple prism sheets can be evenly arranged on the prism plate. In this way, the light emitted by the light source on the lamp board 31 can pass through the light-transmitting plate 32, and then the diffuser 33 formed by the multiple 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.

[0038] Furthermore, a number of clips 341 can be set on the lamp cover 34, and a number of slots 13 can be set on the inner side of the light outlet. The above-mentioned clips 341 are connected to the above-mentioned slots 13 one by one. In this way, the lamp cover 34 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.

[0039] Furthermore, a supporting step 111 can be provided on the inner wall of the mounting opening, so that a positioning end face can be formed; and the end of the second heat dissipation rib 12 is flush with the supporting step 111, and the lamp cover 34 is sealed on the mounting opening and abuts against the supporting step 111, so that when assembling the parts in the lamp holder assembly, the positioning end face formed by the supporting step 111 can achieve the effect of positioning assembly, thereby avoiding loosening or displacement of the parts in the lamp holder assembly.

[0040] Furthermore, a reinforcing rib 14 is provided in the installation cavity 11 , and the reinforcing rib 14 is connected between two adjacent sections of the first heat dissipation rib 12 , thereby improving the overall strength of the installation cavity 11 and thus enhancing the overall structural strength of the desk lamp.

[0041] Furthermore, the lamp housing 10 is integrally formed with aluminum profiles, which can enhance the overall structural strength of the desk lamp, improve the heat dissipation performance inside the lamp housing 10, reduce the risk of excessive temperature due to heat dissipation problems during use, and extend the overall service life of the desk lamp.

[0042] 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.
