[0084] Specifically, the third positioning portion 132 is arranged on the inner side wall of the frame 100, and the third positioning portion 132 has a fifth radial positioning surface 1321; the lens assembly 500 has a third connecting lug 540, and the third connecting lug 540 has a sixth radial positioning surface 541, when the sixth radial positioning surface 541 is attached to the fifth radial positioning surface 1321, the coincidence degree of the central axis of the lens assembly 500 and the central axis of the frame 100 can be ensured.

[0085] It should be noted that the fifth radial positioning surface 1321 is arranged parallel to the central axis of the frame 100, and the sixth radial positioning surface 541 is arranged parallel to the central axis of the lens assembly 500; the perpendicular line between the plane where the fifth radial positioning surface 1321 is located and the central axis of the frame 100 coincides with the perpendicular line between the plane where the sixth radial positioning surface 541 is located and the central axis of the lens assembly 500; and the distance between the plane where the fifth radial positioning surface 1321 is located and the central axis of the frame 100 is the same as the distance between the plane where the sixth radial positioning surface 541 is located and the central axis of the lens assembly 500. In this way, when the sixth radial positioning surface 541 is attached to the fifth radial positioning surface 1321 during the assembly of the lens assembly 500 to the frame 100, it can indicate that the lens assembly 500 has been assembled in place, and at this time, the coincidence degree of the central axis of the lens assembly 500 and the central axis of the frame 100 can be ensured.

[0086] Further, the third positioning portion 132 is also provided with a fifth mounting hole 1322 opened from the fifth radial positioning surface 1321, and the third connecting lug 540 is provided with a sixth mounting hole corresponding to the fifth mounting hole 1322, so that the third fastener can be passed through the fifth mounting hole 1322 and the sixth mounting hole, thereby realizing the fixation of the lens assembly 500 and the frame 100. Wherein, the third fastener can be a screw, the fifth mounting hole 1322 is a threaded hole, and the sixth mounting hole is a through hole.

[0087] In combination with Figure 4 , Figure 6 and Figure 7 , it should be noted that the third positioning structure 130 further includes a third slot 131, and the extension direction of the third slot 131 is perpendicular to the central axis of the frame 100, and the lens assembly 500 is inserted into the third slot 131.

[0088] Specifically, the third slot 131 is arranged on the inner side wall of the frame 100, and the length direction of the third slot 131 is perpendicular to the central axis of the frame 100; the lens assembly 500 is inserted into the third slot 131, and the third slot 131 can position the lens assembly 500, thereby ensuring the coaxiality of the central axis of the lens assembly 500 and the central axis of the frame 100.

[0089] Further, the fifth radial positioning surface 1321 is located on the assembly path of the sixth radial positioning surface 541, so that when the sixth radial positioning surface 541 is in contact with the fifth radial positioning surface 1321 during the assembly of the lens assembly 500 to the frame 100 through the third slot 131, it can indicate that the lens assembly 500 has been assembled in place, at which time, the coincidence of the center axis of the lens assembly 500 and the center axis of the frame 100 can be ensured.

[0090] In combination Figure 1 , Figure 2 with Figure 3 , it should be noted that the frame 100 has openings on both sides, and the extension direction of the first slot 111, the second slot 121 and the third slot 131 is the same as the spacing direction of the openings on both sides of the frame 100; the pattern and CMY assembly 300, the beam cutting assembly 400 and the lens assembly 500 can be inserted into the first slot 111, the second slot 121 and the third slot 131 through the openings on the frame 100, respectively.

[0091] Further, the lamp further comprises a face cover 700 for covering the openings on both sides of the frame 100. The seal ring can be arranged between the frame 100 and the face cover 700, which will not affect the coaxiality of the optical axis of each assembly and the light source assembly 200; after opening the face cover 700, each assembly can be disassembled, which is very convenient for maintaining and repairing the internal assemblies of the lamp.

[0092] In combination Figure 8 with Figure 9 , the lens assembly 500 comprises a mounting bracket 510 and a lens group 520, the mounting bracket 510 is used for mounting the lens group 520, and the mounting bracket 510 is used for connecting with the frame 100; wherein the assembly precision of the mounting bracket 510 itself determines the mounting precision of the lens group 520.

[0093] The mounting bracket 510 comprises a support plate assembly 511 and a side plate assembly 512, wherein the support plate assembly 511 comprises a support plate 5111 and a positioning member 5112 arranged on the support plate 5111, and the side plate assembly 512 is connected with the positioning member 5112.

[0094] As Figure 9 to Figure 11As shown, specifically, the support plate 5111 has a support surface 51111, which is an upper surface of the support plate 5111 and has a planar structure, wherein the support surface 51111 is arranged perpendicularly to the central axis of the frame 100; the positioning members 5112 are arranged on the support surface 51111, and each of the positioning members 5112 has a first positioning surface 51121, which also has a planar structure, and the positioning members 5112 are arranged on the support plate 5111 such that the first positioning surfaces 51121 are arranged perpendicularly to the support surface 51111; the side plate assembly 512 has a first positioning side surface 51211, which has a planar structure, and the side plate assembly 512 is connected to the positioning members 5112 such that the first positioning side surface 51211 is arranged in abutment with the first positioning surfaces 51121.

[0095] It can be understood that the positioning members 5112 are arranged on the support plate 5111 such that the first positioning surfaces 51121 are arranged perpendicularly to the support surface 51111, and by arranging the first positioning side surface 51211 of the side plate assembly 512 in abutment with the first positioning surfaces 51121, the perpendicularity of the side plate assembly 512 to the support plate 5111 can be improved.

[0096] The lens group 520 is connected to the side plate assembly 512, and the side plate assembly 512 is used to support the lens group 520.

[0097] It can be understood that by improving the perpendicularity of the side plate assembly 512 to the support plate 5111, after the lens group 520 is connected to the side plate assembly 512, the risk of the lens group 520 being tilted can be reduced, and thus the assembly precision of the lens group 520 can be improved, thereby improving the coaxiality of the central axis of the lens group 520 to the central axis of the frame 100.

[0098] Specifically, in this embodiment, the number of the side plate assemblies 512 and the number of the positioning members 5112 are both two, the two positioning members 5112 are arranged side by side and spaced apart on the support plate 5111, and the two side plate assemblies 512 are connected to the two positioning members 5112, respectively. Among them, the lens group 520 is connected between the two side plate assemblies 512, and the two side plate assemblies 512 simultaneously support the lens group 520. By using the two side plate assemblies 512 to jointly support the lens group 520 and connecting the lens group 520 between the two side plate assemblies 512, the pressure on each side plate assembly 512 from the lens group 520 can be more uniform, thereby reducing the risk of the side plate assembly 512 being tilted under the pressure of the lens group 520, and further improving the assembly precision of the lens group 520.

[0099] As shown in FIG. 5, the side plate assembly 512 has a first positioning side surface 51211, which has a planar structure, and the side plate assembly 512 is connected to the positioning members 5112 such that the first positioning side surface 51211 is arranged in abutment with the first positioning surfaces 51121. Figure 9 to Figure 11It should be noted that the positioning member 5112 further comprises a second positioning surface (the lower surface of the positioning member 5112) vertically arranged with the first positioning surface 51121, and the second positioning surface is arranged in abutment with the supporting surface 51111. In this way, when the positioning member 5112 is installed on the supporting plate 5111, the perpendicularity of the first positioning surface 51121 and the supporting surface 51111 can be improved under the cooperation of the second positioning surface and the supporting surface 51111.

[0100] In combination Figure 9 With Figure 10 In the two positioning members 5112, the first positioning surface 51121 of any one of the positioning members 5112 is arranged away from the other positioning member 5112. Figure 2 With Figure 4 In the two side plate assemblies 512, the first positioning side surface 51211 of any one of the side plate assemblies 512 is arranged towards the other side plate assembly 512. The first positioning surfaces 51121 on the two positioning members 5112 are parallel to each other. In this way, the two side plate assemblies 512 are symmetrical to each other after being installed, which is beneficial to improve the stress uniformity of the two side plate assemblies 512 under the pressure of the lens group 520, thereby reducing the risk of tilting of the side plate assembly 512 under the pressure of the lens group 520.

[0101] As Figure 9 shown, it should be noted that the supporting plate 5111 is provided with a first light passing hole 51112 penetrating through the supporting surface 51111, and the axis of the first light passing hole 51112 is perpendicular to the supporting surface 51111, and the first light passing hole 51112 is arranged opposite to the lens group 520.

[0102] It can be understood that the first light passing hole 51112 is coaxially arranged with the optical axis of the light source, and since the axis of the first light passing hole 51112 is perpendicular to the supporting surface 51111, the coaxiality of the side plate assembly 512 and the supporting plate assembly 511 is improved, which is beneficial to improve the coaxiality of the lens group 520 and the first light passing hole 51112.

In this embodiment, two support plate assemblies 511 are provided with guide rails 530, and the guide rails 530 on the two support plate assemblies 511 are oppositely and side by side arranged.

In this way, under the common limiting of the support plate assembly 511 and the top plate assembly 513 to the side plate assembly 512, the risk of shaking of the side plate assembly 512 can be reduced, thereby reducing the risk of deviation of the lens group 520.
