DETAILED DESCRIPTION
[0022] The utility model discloses a light source arrangement of the rectangular shell, and the light source arrangement comprises a rectangular shell, a first light source, a first lamp plate, a second light source and a second lamp plate. Figure 1 and the attached Figure 3The application discloses a splicable double-light-source pixel matrix lamp, which comprises a plurality of first light sources 11 arranged in an array on a first lamp plate 12 and a plurality of second light sources 21 arranged in an array on a second lamp plate 22; the first lamp plate 12 and the second lamp plate 22 are vertically and horizontally spaced apart, and the first lamp plate 12 is located directly below the second lamp plate 22; the first lamp plate 12 and the second lamp plate 22 are both rectangular plates, the second lamp plate 22 is coaxially arranged with the first lamp plate 12, and the second lamp plate 22 can completely cover the first lamp plate 12; a plurality of studs are arranged between the first lamp plate 12 and the second lamp plate 22, one end of the stud is used for pressing and locking the first lamp plate 12 on a lamp housing, and the other end is used for abutting against the second lamp plate 22; the stud is connected and fixed with the second lamp plate 22 by using a fixing member; the first lamp plate 12, the first light source 11, the stud, the second lamp plate 22, the second light source 21 and the fixing member are sequentially arranged in a light emitting direction.
[0023] The number of the second light sources 21 is four times that of the first light sources 11, the second light sources 21 are not overlapped with other second light sources 21 surrounding the adjacent first light sources 11; that is, the four second light sources 21 surrounding any first light source 11 are only distributed around the corresponding first light source 11 and cannot be used to surround another adjacent first light source 11; the first light source 11 is located on the central axis of the square formed by the four second light sources 21 closest to the first light source 11, and the plurality of second light sources 21 distributed around the central axis are all single light sources; the distribution density of the second light sources 21 is higher than that of the first light sources 11, and the first light sources 11 are located below the second light sources 21; since the first light sources 11 and the second light sources 21 are not arranged on the same plane, the plurality of first light sources 11 and the plurality of second light sources 21 need to be distributed in a staggered manner; so as to ensure that the second light sources 21 do not block the first light sources 11 and affect the light emitting effect.
[0024] In terms of the light effect formed by the first light sources 11 and the second light sources 21:
[0025] The light emitting angle of the light emitted by the first light source 11 is small, and the light effect formed is a light beam effect; when a plurality of first light sources 11 work simultaneously, the light effect formed is a plurality of light beams; the light emitted by the second light source 21 has a wide light emitting angle and can realize large-area irradiation, and can be used as a projection lamp for extensive illumination; when a plurality of second light sources 21 work simultaneously, a large-area rendering light effect can be created; the first light source 11 and the second light source 21 can also work simultaneously, and the light effect formed has both rendering effect and light beam effect.
[0026] As can be understood by those skilled in the art, the second light source 21 can also serve as a pixel point of the display screen to display diversified patterns and animations, and the array arrangement of the second light source 21 can also make the display screen be spliced.
[0027] The beneficial effect of this embodiment is that the first light source 11 and the second light source 21 are uniformly arrayed, which can form a uniform and rich light effect, and the second light source 21 will not block the light emitted by the first light source 11.
[0028] As a new embodiment, combined with the accompanying drawings Figure 3 and the accompanying drawings Figure 4 The distance between any two adjacent second light sources 21 is L1, and the distance between any two adjacent first light sources 11 is L2=L2=2*L1. In this embodiment, the distance between any two adjacent first light sources 11 is equal, and the distance between any two adjacent second light sources 21 is equal. The beneficial effect of this embodiment is that when L2=2*L1, the first light source 11 is located on the central axis of the square formed by the four second light sources 21; the distance between the two adjacent first light sources 11 is large enough to reserve sufficient space for the wiring of the first light plate 12; at this time, the first light source 11 and the second light source 21 are installed on different axes in the light emitting direction, that is, they are regularly staggered, which can effectively prevent the second light source 21 from blocking the light emitted by the first light source 11; therefore, when the first light source 11 and the second light source 21 work at the same time, a more uniform light effect can be formed.
[0029] As a new embodiment, combined with the accompanying drawings Figure 1 It also includes a lamp body, which includes a rectangular groove 31 for accommodating the first light plate 12 and the second light plate 22 and a rectangular shell 3 for splicing. The first light plate 12 is installed inside the rectangular groove 31 through a stud, and the second light plate 22 is connected with the first light plate 12 through a stud; the shape of the rectangular groove 31 is more suitable for the first light plate 12 and the second light plate 22, and the first light source 11 on the first light plate 12 and the second light source 21 on the second light plate 22 are arrayed, and the arrayed light sources are more beautiful when matched with the rectangular shell; compared with the circular shell, the multiple side surfaces of the rectangular shell 3 are more conducive to the seamless splicing of multiple lamps in the horizontal or vertical direction. The beneficial effect of this embodiment is that the shape of the rectangular groove 31 is suitable for the first light plate 12 and the second light plate 22, and the arrayed light sources are more beautiful when matched with the rectangular groove 31; the rectangular shell 3 is conducive to the seamless splicing of multiple lamps.
[0030] As a new embodiment, combined with the accompanying drawings Figure 3 and the accompanying drawings Figure 4The maximum distance L3 between the center point of any second light source 21 closest to the rectangular shell 3 and the outer surface of the rectangular shell 3 is L3=L1 / 2. The outer surface 32 of the rectangular shell is not entirely flat, and the maximum distance L3 is the distance between the center point of the second light source 21 and the surface plane of the rectangular shell 3; therefore, the spacing L1 between the outermost second light source 21 and the adjacent second light source 21 located at the outermost position of another spliced lamp is the same; when the second light sources 21 located on multiple lamps are working, a relatively uniform light effect can be formed, and the splicing area will not have a local brightness inconsistency. The beneficial effect of this embodiment is that it is beneficial to realize that the spacing L1 between every two adjacent second light sources 21 located at the outermost positions of different spliced lamps is equal when multiple lamps are spliced; a light effect with consistent and relatively uniform brightness can be formed, and the phenomenon of local brightness inconsistency in the splicing area is prevented.
[0031] As a new embodiment, in combination with the accompanying drawings Figure 1 and the accompanying drawings Figure 2 The outer surface 32 on both sides of the rectangular shell 3 is symmetrically provided with a recessed buckle groove 33 and a recessed half I-shaped splicing groove 34, and the buckle groove 33 is located above the splicing groove 34. The length of the splicing groove 34 and the length of the buckle groove 33 tend to be the same as the length of the outer surface on both sides; the splicing groove 34 can not only be used for seamless splicing, but also be used for installing a support; when the splicing groove 34 is used to connect two lamps, due to the shape of the splicing groove 34, the connecting piece for vertically connecting the two lamps should be an I-shaped connecting piece; the length of the connecting piece can be shorter than the length of the splicing groove 34; the connecting piece can be pushed into the splicing groove through the openings at both ends of the splicing groove 34, while only one end of the buckle groove 33 is provided with an opening, and the other end is provided with a limiting plate for limiting; when the splicing groove 34 is used to install a support, the connecting part of the support of the lamp is adapted to the shape of the splicing groove 34, and the width of the connecting part of the support can be shorter than the length of the splicing groove 34; the support of the lamp is also pushed into the splicing groove 34 through the openings at both ends of the splicing groove 34, and the support can also rotate around the connecting part. The beneficial effect of this embodiment is that the splicing groove 34 located on the outer surface of the rectangular shell 3 is beneficial to the seamless splicing between multiple lamps, simplifies the splicing method, and also realizes stable splicing between multiple lamps; the buckle groove 33 is located above the splicing groove 34, and when the splicing groove 34 is used, it does not hinder the use of the buckle groove 33.
[0032] As a new embodiment, in combination with the accompanying drawings Figure 5 and the accompanying drawings Figure 6The unobstructed light-emitting angle of the second light source 21 close to the inner surface 311 of the rectangular groove is θ1≥120°. The unobstructed light-emitting angle includes the light-emitting angle of the second light source 21 under the condition that the second light source 21 is not blocked by any adjacent edge of the rectangular groove 31 in the light-emitting direction. In this embodiment, since θ1≥120°, the second light source 21 closest to the inner surface 311 of the rectangular groove 31 is not blocked by the edge of the rectangular groove 31, and the light-emitting effect of the second light source 21 after the multiple lamps are spliced will not be affected. When θ1<120°, the edge of the rectangular groove 31 will block the light emitted by the second light source 21 closest to the inner surface 311 of the rectangular groove 31. When the multiple lamps are spliced, since the edge of the rectangular groove 31 blocks part of the light emitted by the second light source 21 close to the edge of the rectangular groove 31, a black gap will exist in the light effect of the spliced area. The beneficial effect of this embodiment is that the light emitted by the second light source 21 can not be blocked, and the second light source 21 can achieve large-area illumination. At the same time, when the multiple lamps are spliced, the light effect of the spliced area will not have a black gap.
[0033] As a new embodiment, the accompanying drawings Figure 1 and accompanying drawings Figure 5Also include diffusion plate 4, diffusion plate 4 includes diffusion flat plate 41 and is located on both sides of diffusion flat plate 41 hook part 42, diffusion flat plate 41 and rectangular shell 3 end face in the direction of light tight. The traditional flat plate type diffusion plate is covered on the rectangular groove body, the size of the diffusion plate is less than the size of the groove body, the upper surface of the diffusion plate is lower than the groove upper edge; Therefore, the edge of the rectangular shell 3 will block the light emitted by the outermost second light source 21 adjacent to the edge of the rectangular shell 3, resulting in the unobstructed light emitting angle θ1 of the outermost second light source 21 adjacent to the edge of the rectangular shell 3 < 120°; The diffusion plate 4 of the utility model is " " shaped, the diffusion plate 4 is covered on the upper edge of the rectangular shell 3; The size of the diffusion plate 4 is greater than the size of the rectangular groove 31, at this time, the edge of the rectangular shell 3 will not block the light emitted by the second light source 21, and the unobstructed light emitting angle θ1 of the outermost second light source 21 adjacent to the edge of the rectangular shell 3 is ≥ 120°; The light emitted by the second light source 21 can pass through the diffusion flat plate 41 without obstruction; Compared with the traditional flat plate type diffusion plate, the structure of the diffusion plate 4 effectively solves the problem that the edge of the rectangular shell affects the light emitting effect of the outermost second light source 21 adjacent to it; The hook part 42 of the diffusion plate 4 is matched with the buckle groove 33 of the rectangular shell 3, and the diffusion plate 4 is buckled in the buckle groove 33 of the rectangular shell 3 by pushing; The length of the diffusion flat plate 41 is slightly greater than the length of the hook part 42 on both sides of the diffusion flat plate 41, one end of the hook part 42 is aligned with the diffusion flat plate 41, and the other end is slightly shorter than the diffusion flat plate 41; One end of the buckle groove 33 of the rectangular shell 3 is provided with a limiting plate for limiting the diffusion plate 4, and the end of the hook part 42 which is slightly shorter than the diffusion flat plate 41 abuts against the limiting plate on the buckle groove 33 of the rectangular shell 3; In this embodiment, the diffusion plate 4 can be optionally installed on the rectangular shell 3; When the diffusion plate 4 is not installed on the rectangular shell 3, the lamp can be used as a lighting lamp or as a splicable display screen; When the diffusion plate is installed on the rectangular shell, the lamp is only used as a lighting lamp; Unless the diffusion plate 4 has high light transmittance, i.e. the outline of the second light source 21 can be clearly seen from the outside of the lamp through the diffusion plate 4. The beneficial effects of this embodiment are that the light emitted by the first light source 11 and the second light source 21 can be more diffused and soft, and the diffusion plate 4 will not block the light emitted by the second light source 21 after installation.
[0034] As a new embodiment, the accompanying drawings are combined Figure 5, the diffusion plate 4 is a light-transmitting material with atomization effect. When the rectangular shell 3 is installed with the diffusion plate 4, the first light source 11 can only be used as large-area lighting; due to the atomization effect of the diffusion plate 4, the outlines of the first light source 11 and the second light source 21 cannot be clearly seen outside the lamp; the light-emitting angle of the first light source 11 is small, and the light beam effect is formed by the light emitted by the first light source 11; the light-emitting angle of the second light source 21 is large, and the lamp with the same can be used as a large-area rendering spotlight; after the diffusion plate 4 is installed, the light beam effect formed by the light emitted by the first light source 11 is more soft, and the boundary of the blurred light beam edge is blurred; the light emitted by the second light source 21 can be better mixed to perform large-area lighting. The beneficial effect of this embodiment is that the light emitted by the first light source 11 and the second light source 21 is more soft, and the second light source 21 can form a better lighting effect.
[0035] As a new embodiment, in combination with the accompanying drawings Figure 1 and the accompanying drawings Figure 5 , the first lens 5 for changing the light-emitting angle of the first light source 11 is also included, and the first lens 5 is installed on the first lamp plate 12. The diameter of the light-emitting surface of the first lens 5 is larger than the diameter of the light-entering surface, and the light-entering surface is provided with a buckle for being buckled on the first lamp plate 12; the first lens 5 covers the first light source 11, the side surface of the first lens 5 is a total reflection surface, and the light emitted by the first light source 11 will not leak out from the side surface of the first lens 5. The beneficial effect of this embodiment is that the light emitted by the first light source 11 can be focused, and the loss of the light emitted by the first light source 11 can be effectively reduced; the light-emitting angle of the light emitted by the first light source 11 is changed.
[0036] As a new embodiment, in combination with the accompanying drawings Figure 1 and the accompanying drawings Figure 3 , the second lamp plate 22 is also provided with a through hole 221 for avoiding each first lens 5, and the top of the first lens 5 protrudes from the second lamp plate 22. The through hole 221 on the second lamp plate 22 is located in the square area surrounded by the four second light sources 21 around the first light source 11, and is coaxial with the first light source 11; the diameter of the through hole 221 is slightly larger than the diameter of the light-emitting surface of the first lens 5, and the height of the light-emitting surface of the first lens 5 should be higher than the height of the glue surface after glue pouring, so as to prevent the light-emitting effect of the first light source 11 from being affected after glue pouring; the first lens 5 is provided with a limiting ring 51, and the upper surface of the limiting ring 51 is in close contact with the lower surface of the second lamp plate 22; the first lens 5 can be effectively prevented from being displaced, and the light emitted by the first light source 11 can be prevented from leaking out from the limiting ring 51, so as to change the light-emitting angle of the first light source 11. The beneficial effect of this embodiment is that the first lens 5 can project the light emitted by the first light source 11 outside the lamp, and prevent the second lamp plate 22 from blocking the light emitted by the first light source 11.
