[0043] For example, some low-position desk lamps on the market currently use the principle of reflection to achieve anti-glare, that is, by illuminating the reflector with the light source. However, in actual use, although it can effectively reduce the harm of glare, the lighting effect is not good, and the reflector is not firmly fixed and is easy to fall off, and it is also unsightly. Therefore, this utility model proposes an ultrasonic welding type low-position desk lamp.

[0044] like Figure 1 As shown, the low-position desk lamp of this utility model includes a lamp holder assembly, a reflector light guide assembly, and a light source assembly.

[0045] like Figure 1 and Figure 2As shown, the lamp holder assembly includes a support base 100 and a lamp frame 110. The support base 100 is vertically arranged and cylindrical. In some other embodiments, the support base 100 may have other shapes. The lamp frame 110 is located on the top side of the support base 100. The lamp frame 110 is provided with a connecting portion 120 and a hollow portion 130. The connecting portion 120 is located between the lamp frame 110 and the support base 100, and the lamp frame 110 is suspended from the top of the support base 100 through the connecting portion 120. The hollow portion 130 is also located above the support base 100 and extends laterally to the outer periphery of the upper part of the support base 100. The hollow portion 130 is arranged vertically and continuously. Specifically, as shown... Figure 1 As shown, the connecting part 120 is located at the rear between the lamp frame 110 and the support base 100, while the hollow part 130 is located at the front between the lamp frame 110 and the support base 100. One part of the hollow part 130 is located directly above the top surface of the support base 100, while the other part extends forward. The hollow part 130 is provided with a first mounting step 131 around its perimeter.

[0046] like Figure 3 and Figure 4 As shown, the reflective light guide assembly includes a top cover plate 200 and a reflective light guide plate 300. The shape and size of the reflective light guide plate 300 match the hollow part 130. The four sides of the reflective light guide plate 300 abut against the first mounting step 131. The first mounting step 131 limits and fixes the reflective light guide plate 300. The top cover plate 200 covers the top of the lamp frame 110 and presses the reflective light guide plate 300. During assembly, the reflective light guide plate 300 is first placed horizontally on the first mounting step 131, and then the top cover plate 200 is installed.

[0047] In this embodiment, the top cover plate 200 is ultrasonically welded to the lamp frame 110 around its perimeter, thereby fixing the top cover plate 200 so that the reflective light guide plate 300 can be fixedly installed in the hollow part 130.

[0048] For the installation and fixing of the reflective light guide plate 300, the reflective light guide plate 300 is limited by the first installation step 131 and is also pressed and fixed by the top cover plate 200. The top cover plate 200 is fixed to the lamp frame 110 by ultrasonic welding to improve the firmness and aesthetics of the installation.

[0049] like Figure 1 , Figure 3 As shown, a light-emitting hole 140 is provided on the top surface of the support base 100. The light-emitting hole 140 faces the bottom surface of the reflective light guide plate 300 and is connected to the interior of the support base 100.

[0050] like Figure 3As shown, the light source assembly includes a main light source 400 and an auxiliary light source 500. The main light source 400 is located inside the support base 100 and illuminates the bottom surface of the reflective light guide plate 300 through the light outlet 140. The auxiliary light source 500 is located on the outer periphery of the reflective light guide plate 300 and is installed inside the lamp frame 110. The auxiliary light source 500 illuminates the outer surface of the reflective light guide plate 300.

[0051] In this embodiment, the main light source 400 is located inside the support base 100, and the auxiliary light source 500 is located inside the lamp frame 110 on the outside of the reflective light guide plate 300 to form a hidden light source design. The light from the main light source 400 illuminates the reflective light guide plate 300 through the light outlet 140, so that the light is reflected by the reflective light guide plate 300. At the same time, the auxiliary light source 500 also illuminates the outer surface of the reflective light guide plate 300 to achieve light guiding, improve the lighting effect, effectively reduce glare hazards, and create a healthier, safer, and more comfortable lighting environment.

[0052] Furthermore, such as Figure 2 and Figure 4 As shown, the lamp frame 110 of this embodiment is provided with a second mounting step 111 around its perimeter, and the top cover plate 200 abuts against the second mounting step 111 around its perimeter. During assembly, the top cover plate 200 is limited and installed by the second mounting step 111, and then ultrasonic welding is performed to improve the accuracy and firmness of the installation.

[0053] In this embodiment, the hollowed-out portion 130 extends forward from the connecting portion 120 toward the outer periphery of the support base 100, so that the light from the main light source 400 is reflected by the reflective light guide plate 300 and then shines forward and downward.

[0054] like Figure 2 , Figure 5 and Figure 6 As shown, the reflective light guide plate 300 has a notch 310 on one side near the connecting part 120. It can be understood that the notch 310 is located on the rear side of the reflective light guide plate 300. The connecting part 120 has a protrusion 121 extending into the notch 310. The auxiliary light source 500 includes a plurality of auxiliary lamp beads 510 evenly distributed on the outer side of the protrusion 121. In this embodiment, the side of the notch 310 is illuminated by the plurality of auxiliary lamp beads 510 to increase the illumination range, thereby increasing the light guiding amount of the reflective light guide plate 300.

[0055] In this embodiment, the notch 310 is triangular, and the protrusion 121 is also triangular. Multiple auxiliary lamp beads 510 illuminate the reflective light guide plate 300 from the two inner sidewalls of the notch 310, so that the light is conducted in two directions in the reflective light guide plate 300 to form the effect of ambient lighting.

[0056] like Figure 3As shown, the main light source 400 in this embodiment includes a main lamp bead 410 and a condenser 420. The inner peripheral wall of the condenser 420 is arc-shaped. The main lamp bead 410 is disposed inside the condenser 420. The condenser 420 is provided with a light outlet 421 facing the light outlet 140.
