Description

Technical Field

[0001] This utility model relates to the technical field of lighting, and in particular to an ultrasonically welded eye-protecting lamp holder and an eye-protecting desk lamp. Background Technology

[0002] A desk lamp is a common household appliance used to provide light at night. When using a desk lamp, especially when children are studying, the quality of the light is closely related to the user's eyesight. Eye-protecting reading lamps use special light source technology to provide softer, more even light, reducing eye strain from strong light and glare.

[0003] Existing eye-protection desk lamps consist of a lamp head and a lamp base. To expand the illumination range and achieve anti-glare effects, existing lamp heads generally have multiple light sources. Due to the multiple light sources, the size of the lamp head increases, as does the number of internal parts. This increases the requirements for the assembly firmness of the lamp head, which is currently assembled and fixed with screws. However, the presence of screw holes affects the overall aesthetics of the lamp head. Furthermore, to improve firmness, many screws are used for connection and fixation, making the operation cumbersome, the assembly inconvenient, and often resulting in the omission of screws.

[0039] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0040] Existing eye-protection desk lamps include a lamp head and a lamp base 500. In order to expand the illumination range and achieve the effect of anti-glare, existing lamp heads generally have multiple light sources. Due to the multiple light sources, the size of the lamp head increases, and the number of internal parts also increases. The requirements for the assembly firmness of the lamp head also increase. Currently, it is assembled and fixed by screws. However, the presence of screw holes affects the overall aesthetics of the lamp head. In addition, in order to improve the firmness, many screws are used for connection and fixation, which is cumbersome and inconvenient to assemble, and screws are often missed. Therefore, this utility model proposes an ultrasonically welded eye-protection lamp head 400.

[0041] like Figure 1 As shown, the eye-protection lamp head 400 of this embodiment includes: a housing 100 and a light-emitting device.

[0042] The housing 100 includes an upper housing 110 and a lower housing 120. A snap-fit ​​pre-tightening structure is provided between the upper housing 110 and the lower housing 120. During assembly, the snap-fit ​​pre-tightening structure snaps the upper housing 110 and the lower housing 120 together to achieve pre-tight assembly and to make the four sides of the upper housing 110 and the lower housing 120 fit together. The four sides of the upper housing 110 and the lower housing 120 are ultrasonically welded together to reinforce the upper housing 110 and the lower housing 120.

[0043] In this embodiment, the bottom surface of the lower housing 120 is provided with multiple light-emitting ports at intervals, and the number and shape of the light-emitting ports are determined according to actual needs.

[0044] The light-emitting device includes multiple light-emitting components, which are sandwiched inside the upper housing 110 and the lower housing 120. Each light-emitting component corresponds to a light-emitting port, and the light emitted by the light-emitting components shines out from the light-emitting ports.

[0045] In this embodiment, multiple light-emitting components are arranged between the upper housing 110 and the lower housing 120. The upper housing 110 and the lower housing 120 are snapped together by a snap-fit ​​pre-tightening structure to achieve pre-tightening. Then, ultrasonic welding is performed on the four sides of the upper housing 110 and the lower housing 120 to clamp the multiple light-emitting components between the upper housing 110 and the lower housing 120. This improves the overall structural strength of the eye-protection lamp head 400. Compared with traditional screwing, there are no screw heads and screw holes on the outer surface, which improves the aesthetics. Secondly, it facilitates assembly, as the light-emitting components can be pre-tightened. Then, the connection between the upper housing 110 and the lower housing 120 is reinforced by ultrasonic welding. In addition, it also improves the waterproof performance of the eye-protection lamp head 400.

[0046] like Figure 1 , 2 As shown in Figure 3, a downwardly extending control panel 111 is provided in the middle of the front side of the upper housing 110, and a downwardly recessed clearance groove 121 is provided in the middle of the front side of the lower housing 120. The control panel 111 and the clearance groove 121 are matched and engaged to form a three-dimensional curved welding line 130 between the upper housing 110 and the lower housing 120. When ultrasonic welding is performed on the upper housing 110 and the lower housing 120, welding is performed along the welding line 130 to improve the aesthetics of the housing 100.

[0047] The control panel 111 in this embodiment is used by the user to adjust the brightness, start / stop and lighting combination mode of the light-emitting component.

[0048] To further improve the accuracy and stability of the installation of light-emitting components, such as Figure 3 As shown, multiple mounting slots 112 are provided in the bottom of the upper housing 110, and multiple light-emitting components are installed in the mounting slots 112 one by one. Before assembly, the light-emitting components are pre-installed in the mounting slots 112 for installation and positioning. Then the upper housing 110 and the lower housing 120 are closed. The mounting slots 112 can prevent the light-emitting components from moving in the housing 100.

[0049] like Figure 2 and 3 As shown, the snap-fit ​​pre-tightening structure of this embodiment includes multiple snap-fits 122 and multiple snap-fit ​​slots 113. The multiple snap-fits 122 are arranged at intervals along the inner edge of the lower housing 120, while the multiple snap-fit ​​slots 113 are arranged at intervals along the inner edge of the upper housing 110. When the upper housing 110 and the lower housing 120 are fitted together, the snap-fits 122 and the snap-fit ​​slots 113 snap together. In some embodiments, the multiple snap-fits 122 may be provided in the upper housing 110, while the multiple snap-fit ​​slots 113 may be provided in the lower housing 120.

[0050] Furthermore, in order to improve the accuracy of the fitting of the upper housing 110 and the lower housing 120, such as Figure 2 and 3 As shown, in this embodiment, a positioning structure is provided between the upper housing 110 and the lower housing 120. The positioning structure includes multiple positioning posts 114 and multiple positioning grooves 123. In this embodiment, the multiple positioning posts 114 are distributed in the upper housing 110, and the multiple positioning grooves 123 are distributed in the lower housing 120. When the upper housing 110 and the lower housing 120 are fitted together, the positioning posts 114 are inserted into the positioning grooves 123, and the positioning posts 114 extend in the vertical direction.

[0051] In some embodiments, the positioning post 114 is disposed on the lower housing 120, and the positioning groove 123 is disposed on the upper housing 110.

[0052] like Figure 2 As shown, the machine housing 100 in this embodiment is a left-right symmetrical component. Correspondingly, the upper housing 110 and the lower housing 120 are also left-right symmetrical components. A ball joint connection part 115 is provided on the rear side of the center of the top surface of the upper housing 110. In use, the external connection structure is hinged to the ball joint connection part 115 to support the eye protection lamp head 400, so that the left and right ends of the eye protection lamp head 400 are balanced and can be adjusted in all directions. The ball joint connection part 115 in this embodiment is a groove structure.

[0053] like Figure 2 and 3As shown, in this embodiment, soft covers 140 are provided at the left and right ends of the housing 100, respectively. The soft covers 140 are fixed by snap-fit ​​to facilitate assembly. The soft covers 140 can protect the user and prevent the user from being injured by bumping into the left and right ends of the housing 100.

[0054] In order to achieve, such as Figure 4 As shown, an anti-glare section 150 extending downwards is provided on the front side of the light outlet, so that the user's eyes cannot look directly at the light-emitting surface when in a normal sitting posture, thus achieving an anti-glare design.

[0055] like Figure 1 , 2 As shown in Figure 3, the multiple light-emitting ports in this embodiment are divided into a main light-emitting port 124 located in the middle of the lower housing 120 and two auxiliary light-emitting ports 125 located on the left and right sides of the main light-emitting port 124. The main light-emitting port 124 has a circular opening structure, and the auxiliary light-emitting ports 125 have a strip-shaped opening structure extending from left to right.

[0056] like Figure 1 , 2 As shown in Figure 3, the multiple light-emitting components are divided into a main light-emitting component 300 corresponding to the main light-emitting port 124 and an auxiliary light-emitting component 200 corresponding to the auxiliary light-emitting port 125. It can be understood that this embodiment sets two auxiliary light-emitting components 200 and one main light-emitting component 300. The two auxiliary light-emitting components 200 supplement the main light-emitting component 300 to expand the illumination range.

[0057] The main light-emitting component 300 includes a main light-transmitting plate 310 and a main lamp plate 320. The main light-transmitting plate 310 is located at the main light outlet 124, and the main lamp plate 320 is located inside the main light-transmitting plate 310.

[0058] The auxiliary light-emitting component 200 in this embodiment includes an auxiliary light-transmitting plate 210 and an auxiliary lamp plate 220. The auxiliary light-transmitting plate 210 is disposed at the auxiliary light outlet, and the auxiliary lamp plate 220 is disposed inside the auxiliary light-transmitting plate 210.

[0059] In addition, such as Figure 5As shown, this utility model also provides an eye-protecting desk lamp, including the aforementioned eye-protecting lamp head 400, lamp holder 500, and folding support mechanism 600. The folding support mechanism 600 includes at least two support rods 610 connected in sequence. A first hinge structure 620 is provided between two adjacent support rods 610. A ball joint connection structure 630 is provided between one end of the support rod 610 and the housing 100, and a second hinge structure 640 is provided between the other end of the support rod 610 and the lamp holder 500. The ball joint connection structure 630 is hinged to the ball joint connection part 115 to realize the universal adjustment of the eye-protecting lamp head 400. The support rods 610 can be angled through the first hinge structure 620 to meet different illumination needs. The other end of the support rod 610 is hinged to the lamp holder 500 through the second hinge structure 640, which can also be angled. When not in use, the eye-protecting desk lamp can be folded up for storage.
