In one embodiment, the first lamp holes corresponding to the at least two first positioning protrusions are located on the same side of the first center line. In this embodiment, the first central line divides the lamp beads on the substrate into two bilaterally symmetrical parts, that is, the lamp beads on the substrate are symmetrically arranged with the first central line as a central axis, that is, the lamp beads on the substrate are symmetrically arranged on two sides of the first central line respectively. Two protruding directions are opposite or back to each other the first positioning protrusions are respectively located in two first lamp holes, wherein one protruding direction of the first positioning protrusion faces towards the left side of the first center line and is perpendicular to the first center line, the other protruding direction of the first positioning protrusion faces towards the right side of the first center line and is perpendicular to the first center line, namely one protruding direction of the first positioning protrusion faces towards the left side of the first center line and is perpendicular to the second preset direction, the other protruding direction of the first positioning protrusion faces towards the right side of the first center line and is perpendicular to the second preset direction, and the two first positioning protrusions are located on the same side of the center line. The first positioning bulges facing the left side of the first central line in the bulge direction are positioned on the right sides of the corresponding lamp beads, gaps between the lamp beads and the right side wall of the first lamp hole are limited, namely, the distance between the lamp beads and the right side wall of the first lamp hole is determined, so that the position relation between the lamp beads and the right side wall of the first lamp hole is determined, and the positioning between the lamp beads and the right side wall of the first lamp hole is facilitated; the first positioning bulges on the right side of the first central line are positioned on the left sides of the corresponding lamp beads in the protruding direction, gaps between the lamp beads and the left side wall of the first lamp hole are limited, namely, the distance between the lamp beads and the left side wall of the first lamp hole is determined, so that the position relation between the lamp beads and the left side wall of the first lamp hole is determined, and the positioning of the lamp beads and the left side wall of the first lamp hole is facilitated.
Because the lamp beads of the substrate are bilaterally symmetrical, after two lamp beads of one side parallel to the first central line are respectively positioned and determined with the corresponding first positioning bulges, the position relation between the lamp bead of the other side and the corresponding first positioning bulge is determined, and therefore positioning between the lamp beads on the whole substrate and the side wall of the lamp hole on the mask is achieved. A first positioning bulge corresponds to a first lamp hole, when the lamp bead on the substrate is positioned in the direction of the first central line, the space of the first lamp hole occupied by the first positioning bulge is reduced, the safe gap between the lamp bead and the first positioning bulge is ensured, the possibility that the first positioning bulge extrudes the lamp bead is reduced, namely, the damage possibility of the lamp beads in the first lamp hole is reduced, and the two first positioning bulges are respectively positioned near two sides of the first central line, so that an installer can quickly find positioning points on two sides according to the position of the first central line, thereby being convenient for quickly and simultaneously finding the first positioning bulges with two opposite or opposite bulge directions on the substrate, the installation of the face shield and the substrate is further facilitated, and the positioning accuracy between the face shield and the lamp beads 110 on the substrate 100 is improved.

The second lamp holes 212 distributed near the second center line CL2 are located in the middle region of the substrate 100, and the lamp beads 110 positioned with the second lamp holes 212 are also located in the middle of the substrate 100, so that the second lamp holes 212 located in the middle region of the substrate 100 are accurately positioned with the corresponding lamp beads 110. Since the second center line CL2 divides the substrate 100 into two vertically symmetrical parts, when the position between the lamp beads 110 near the second center line CL2 and the corresponding second lamp holes 212 is accurately located, the lamp beads 110 of the two vertically symmetrical parts of the substrate 100 are aligned with the corresponding lamp holes 210, and the lamp beads 110 of the two vertically symmetrical parts of the substrate 100 about the second center line CL2 are aligned with the corresponding lamp holes 210 by adjusting the position relationship between the second lamp holes 212 close to the second center line CL2 and the corresponding lamp beads 110. Thus, after the second lamp holes 212 near the second center line CL2 are aligned with the lamp beads 110, the lamp beads 110 on the two parts of the second center line CL2 that are vertically symmetrical are aligned with the corresponding lamp holes 210. The second positioning protrusion 216 on the sidewall of the second lamp hole 212 is located in the middle of the substrate 100, and one second positioning protrusion 216 corresponds to one second lamp hole 212, so that when the lamp bead 110 on the substrate 100 is positioned in the direction of the second center line CL2, the space of the second lamp hole 212 occupied by the second positioning protrusion 216 is reduced, a safety gap is ensured to be maintained between the lamp bead 110 and the second positioning protrusion 216, the possibility that the second positioning protrusion 216 presses the lamp bead 110 is reduced, that is, the damage possibility of the lamp bead 110 in the second lamp hole 212 is reduced, moreover, the second positioning protrusion 216 is located near the second center line CL2, so that an installer can quickly find a positioning point according to the position of the second center line CL2, thereby being convenient to quickly and simultaneously find two second positioning protrusions 216 with opposite or opposite protruding directions on the substrate 100, the installation of the face shield 200 and the substrate 100 is further facilitated, and the positioning accuracy between the face shield 200 and the lamp beads 110 on the substrate 100 is improved.
