[0002] With the development of lighting equipment, the shapes and lighting effects of lamps are becoming more and more diverse. There is a lighting device for illuminating a wall. Such lighting device includes a circle of lamp beads. The light reflected by the lamp beads is emitted from the peripheral side wall of the lighting device and forms a circle of light surrounding the lighting device on the wall. The lighting device can control multiple lamp beads to emit light of specific colors in sequence to form a dynamic marquee light effect.

[0003] However, the marquee lighting effects created by traditional lighting equipment have low smoothness and poor visual effects. Summary of the invention

[0004] The present application provides a lamp, which includes a light source module, the light source module having a first linear light-emitting portion, a second linear light-emitting portion and an arc light-emitting portion, the first linear light-emitting portion extends in the direction of the first straight line, the second linear light-emitting portion extends in the direction of the second straight line and is arranged opposite to the first linear light-emitting portion with an interval, the arc light-emitting portion extends in the direction of a specified arc, and two ends of the arc light-emitting portion are respectively connected to the first linear light-emitting portion and the second linear light-emitting portion; the light source module includes a plurality of lamp beads, the plurality of lamp beads include a plurality of first lamp beads and a plurality of second lamp beads, the plurality of first lamp beads are distributed in the first linear light-emitting portion and the second linear light-emitting portion, and the plurality of second lamp beads are distributed in the arc light-emitting portion; the arrangement density of the plurality of first lamp beads is less than the arrangement density of the plurality of second lamp beads.

[0005] The present application provides a lamp, which includes a light source module, the light source module having a first linear light-emitting portion extending in the direction where a first straight line is located, a second linear light-emitting portion extending in the direction where a second straight line is located, and an arc light-emitting portion extending in the direction where a specified arc is located, and the two ends of the arc light-emitting portion are respectively connected to the first linear light-emitting portion and the second linear light-emitting portion, so that the lamp has a first linear bright area, a second linear bright area, and an arc bright area, thereby improving the richness of the lighting effect of the lamp. The lamp includes a plurality of lamp beads, the plurality of lamp beads include a plurality of first lamp beads and a plurality of second lamp beads, some of the first lamp beads are sequentially arranged in the first linear light-emitting portion at intervals along the direction where the first straight line is located, some of the first lamp beads are sequentially arranged in the second linear light-emitting portion at intervals along the direction where the second straight line is located, and the plurality of second lamp beads are sequentially arranged in the arc light-emitting portion at intervals along the direction where the specified arc is located. In the present embodiment, the light emitted by two adjacent first lamp beads is approximately parallel, and the distance between the centers of two light spots formed on the wall by the two first lamp beads is approximately the same as the distance between the two first lamp beads; the light emitted by two adjacent second lamp beads gradually moves away from each other during the conduction process, and the distance between the centers of two light spots formed on the wall by the two second lamp beads is greater than the distance between the two second lamp beads. Therefore, in the present embodiment, the arrangement density of the multiple first lamp beads is set to be smaller than the arrangement density of the second lamp beads, that is, the distance between the two first lamp beads is set to be smaller than the distance between the two second lamp beads, so that the distance between the centers of the light spots formed by the adjacent second lamp beads is approximately equal to the distance between the centers of the light spots formed by the two adjacent first lamp beads, that is, the distance between the centers of any two light spots among the multiple light spots formed by the lamp is approximately the same.

[0006] Under the setting of this embodiment, the first straight line, the designated arc, and the second straight line define a chain path of multiple lamp beads, and the multiple lamp beads arranged in a chain can be controlled to form a marquee effect. Specifically, the lamp is provided with a normal light color, such as natural light and beige light. In actual application scenarios, the multiple lamp beads on the chain path can be controlled to sequentially emit marquee light different from the normal light color and form a marquee light spot on the wall. The color of the marquee light can be red, green, etc. As an example, the color of the marquee light is red. When one of the lamp beads emits red marquee light, the lamp bead forms a red light spot on the wall. The red light spot replaces the white light spot or beige light spot originally formed by the lamp bead on the wall. The multiple lamp beads sequentially emit red marquee light along the chain path and form a red light spot. The direct visual effect of the user or observer is that the red light spot moves in the bright area, that is, the marquee light effect. In this embodiment, among the multiple light spots formed by the lamp, the distance between the centers of any two light spots is approximately the same. Therefore, the displacement generated by each movement of the red light spot is approximately the same. Therefore, the marquee light effect is relatively smooth and uninterrupted, which greatly improves the marquee effect of the lamp. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0020] See also Figure 1 The embodiment of the present application provides a lamp 100, which is suitable for being installed on a wall to illuminate the application environment in which it is located, or as a lighting decoration to create a scene light atmosphere. The lamp 100 in this embodiment is a wall lamp, which is applied to a wall. The wall serves as the light receiving surface of the lamp 100. The light emitted by the lamp 100 shines on the wall and forms a bright area 70, which is used to beautify the wall and illuminate the application environment. The lamp 100 can also be used in other environments, such as a display platform with a horizontal support surface, the ground, etc.

[0021] See also Figure 1 and Figure 2In this embodiment, the lamp 100 includes a light source module 10, and the light source module 10 has a first linear light emitting portion 13, a second linear light emitting portion 14, and an arc light emitting portion 15. The first linear light emitting portion 13 extends along the direction where the first straight line is located, and the second linear light emitting portion 14 extends along the direction where the second straight line is located. The first linear light emitting portion 13 and the second linear light emitting portion 14 are arranged with a relative interval, and the light emitted by the first linear light emitting portion 13 forms a first linear bright area 71 on the wall, and the light emitted by the second linear light emitting portion 14 forms a second linear bright area 73 on the wall. The arc light emitting portion 15 extends in the direction of the designated arc, and the light emitted by the arc light emitting portion 15 forms an arc-shaped bright area 72 extending along the arc on the wall. The arc-shaped bright area 72 is arranged around the outer periphery of the arc light emitting portion 15 of the light source module 10. The two ends of the arc light emitting portion 15 in the extending direction are respectively connected to the ends of the first linear light emitting portion 13 and the ends of the second linear light emitting portion 14, so that the two ends of the arc-shaped bright area 72 are respectively connected to the first linear bright area 71 and the second linear bright area 73. The bright area 70 formed by the lamp 100 includes at least a first linear bright area 71, a second linear bright area 73 and an arc-shaped bright area 72.

[0022] In this embodiment, the arc light emitting portion 15 can have various forms, and the shapes formed by the first linear light emitting portion 13, the second linear light emitting portion 14 and the arc light emitting portion 15 can have various shapes. In this embodiment, the arc light-emitting portion 15 extends in the direction of the designated arc, the central angle corresponding to the structure of the arc light-emitting portion 15 is approximately 180°, the first linear light-emitting portion 13 is parallel to the second linear light-emitting portion 14, the first linear light-emitting portion 13 is connected to one end of the arc light-emitting portion 15, the first straight line is approximately tangent to one end of the designated arc, the second linear light-emitting portion 14 is connected to the other end of the arc light-emitting portion 15, and the second straight line is approximately tangent to the other end of the designated arc, so that the three form an approximately "U"-shaped structure, so that the light emitted by the light source module 10 surrounds the light source module 10 and the lamp 100, and the shape of the bright area 70 formed by the lamp 100 is also approximately "U"-shaped and surrounds the lamp 100, and the bright area 70 includes a portion extending along a straight line and a portion extending along an arc (i.e., a first linear bright area 71, a second linear bright area 73 and an arc-shaped bright area 72), so that the lighting effect of the lamp 100 has good integrity and continuity, and the lighting effect of the lamp 100 is relatively novel and aesthetic, and has better ornamental value.

[0023] In other embodiments, the arc light-emitting portion 15 extends in the direction of a specified arc, and the central angle corresponding to the structure of the arc light-emitting portion 15 is less than 180° (such as 135°, 120°, 90°, 45°, 30°, etc.), and the spacing between the first linear light-emitting portion 13 and the second linear light-emitting portion 14 can gradually increase in the direction away from the arc light-emitting portion 15, so that the three form an open structure; the spacing between the first linear light-emitting portion 13 and the second linear light-emitting portion 14 can gradually decrease in the direction away from the arc light-emitting portion 15, so that the three form a closed structure.

[0024] The light source module 10 in this embodiment includes a plurality of lamp beads 11, and the plurality of lamp beads 11 include a first lamp bead 111 and a second lamp bead 112. The plurality of first lamp beads 111 are distributed in the first linear light-emitting portion 13 and the second linear light-emitting portion 14, and the plurality of second lamp beads 112 are distributed in the arc light-emitting portion 15. The plurality of first lamp beads 111 in the first linear light-emitting portion 13 are sequentially arranged at intervals along the direction where the first straight line is located, and the plurality of first lamp beads 111 in the second linear light-emitting portion 14 are sequentially arranged at intervals along the direction where the second straight line is located, so that the first linear bright area 71 and the second linear bright area 73 formed by the first linear light-emitting portion 13 and the second linear light-emitting portion 14 respectively extend along the straight line, and the plurality of second lamp beads 112 in the arc light-emitting portion 15 are sequentially arranged at intervals along the direction where the specified arc is located, so that the arc-shaped bright area 72 formed by the arc light-emitting portion 15 extends along the arc.

[0025] In this embodiment, a plurality of first lamp beads 111 and a plurality of second lamp beads 112 are arranged in sequence and spaced apart to form a lamp bead chain. In some other embodiments, the light source module 10 may include two or more substantially parallel lamp bead chains, that is, the lamp beads 11 are arranged in an array to increase the brightness of the bright area 70 formed by the lamp 100. In such embodiments, a unit area is determined, and the number of first lamp beads 111 provided per unit area on the first linear light-emitting portion 13 is the same as the number of first lamp beads 111 provided per unit area on the second linear light-emitting portion 14, and the number of first lamp beads 111 provided per unit area on the first linear light-emitting portion 13 is less than the number of second lamp beads 112 provided per unit area on the arc light-emitting portion 15. In an embodiment with a plurality of lamp bead chains, the plurality of lamp beads 11 in two adjacent lamp bead chains may be staggered from each other so that the plurality of light spots formed by the lamp 100 on the wall are more evenly distributed.

[0026] In this embodiment, each lamp bead 11 has a maximum lighting distance, the direction of the maximum lighting distance roughly coincides with the optical axis of the lamp bead 11, and the maximum lighting distances of multiple lamp beads 11 (including the first lamp bead 111 and the second lamp bead 112) are the same. Taking the application environment of the present application as an example, when the optical axis of a lamp bead 11 is approximately parallel to the wall, the lamp bead 11 can form a brighter light spot on the wall at a position away from the maximum lighting distance of the lamp bead 11. As can be seen from the foregoing, the optical axes of two adjacent first lamp beads 111 are roughly parallel, the light emitted by the two first lamp beads 111 are roughly parallel, and the spacing between the centers of the two light spots formed by the two first lamp beads 111 on the wall is roughly the same as the spacing between the two. The optical axes of the two adjacent second lamp beads 112 intersect, so the light emitted by the two second lamp beads 112 gradually move away, and the spacing between the centers of the two light spots formed by the two second lamp beads 112 on the wall is greater than the spacing between the two. Therefore, in this embodiment, a plurality of first lamp beads 111 are arranged in an equally spaced array on the first linear light-emitting portion 13 and in an equally spaced array on the second linear light-emitting portion 14, and a second lamp bead 112 is arranged in an equally spaced array on the arc light-emitting portion 15, and the arrangement density of the first lamp beads 111 is set to be smaller than the arrangement density of the second lamp beads 112, that is, the spacing between two adjacent first lamp beads 111 is greater than the spacing between two adjacent second lamp beads 112, and the spacing between the centers of the light spots formed by the adjacent second lamp beads 112 is approximately equal to the spacing between the centers of the light spots formed by the adjacent first lamp beads 111, so that the multiple light spots formed on the wall by the lamp bead chain formed by the multiple first lamp beads 111 and the multiple second lamp beads 112 are arranged at equal intervals, that is, among the multiple light spots formed by the lamp fixture 100, the spacing between the centers of any two light spots is approximately the same. Under the setting of this embodiment, the brightness of the first linear bright area 71, the second linear bright area 73 and the arc-shaped bright area 72 can be made substantially the same, and the brightness difference between two adjacent bright areas is reduced, so that the brightness of each part of the bright area 70 formed by the lamp 100 on the wall is more uniform, and the connection effect between the arc-shaped bright area 72 and the first linear bright area 71 and the second linear bright area 73 is improved, so that the lighting effect of the lamp 100 is smoother.

[0027] In summary, the lamp 100 provided in this embodiment includes a light source module 10, and the light source module 10 has a first linear light emitting portion 13 extending in the direction where the first straight line is located, a second linear light emitting portion 14 extending in the direction where the second straight line is located, and an arc light emitting portion 15 extending in the direction where the specified arc is located, and the two ends of the arc light emitting portion 15 are respectively connected to the first linear light emitting portion 13 and the second linear light emitting portion 14, so that the lamp 100 has a first linear bright area 71, a second linear bright area 73 and an arc bright area 72, thereby improving the richness of the lighting effect of the lamp 100. The lamp 100 includes a plurality of first lamp beads 111 and a plurality of second lamp beads 112, some of the first lamp beads 111 are sequentially arranged in the first linear light emitting portion 13 along the direction where the first straight line is located, and some of the first lamp beads 111 are sequentially arranged in the second linear light emitting portion 14 along the direction where the second straight line is located, and a plurality of second lamp beads 112 are sequentially arranged in the arc light emitting portion 15 along the direction where the specified arc is located. In the present embodiment, the light emitted by two adjacent first lamp beads 111 is approximately parallel, and the spacing between the centers of two light spots formed on the wall by the two first lamp beads 111 is approximately the same as the spacing between the two first lamp beads 111; the light emitted by two adjacent second lamp beads 112 gradually moves away from each other during the transmission process, and the spacing between the centers of two light spots formed on the wall by the two second lamp beads 112 is greater than the spacing between the two second lamp beads 112. Therefore, in the present embodiment, the arrangement density of the multiple first lamp beads 111 is set to be smaller than the arrangement density of the second lamp beads 112, that is, the spacing between the two first lamp beads 111 is set to be smaller than the spacing between the two second lamp beads 112, so that the spacing between the centers of the light spots formed by adjacent second lamp beads 112 is approximately equal to the spacing between the centers of the light spots formed by two adjacent first lamp beads 111, that is, the spacing between the centers of any two light spots among the multiple light spots formed by the lamp 100 is approximately the same.

[0028] Under the setting of this embodiment, the first straight line, the designated arc, and the second straight line define a chain path of multiple lamp beads 11, and the multiple lamp beads 11 arranged in a chain can be controlled to form a marquee effect. Specifically, the lamp 100 is provided with a normal light color, such as natural light and beige light. In actual application scenarios, the multiple lamp beads 11 on the chain path can be controlled to sequentially emit marquee light different from the normal light color and form a marquee light spot on the wall. The color of the marquee light can be red, green, etc. As an example, the color of the marquee light is red. When one of the lamp beads 11 emits red marquee light, the lamp bead 11 forms a red light spot on the wall. The red light spot replaces the white light spot or beige light spot originally formed by the lamp bead 11 on the wall. The multiple lamp beads 11 sequentially emit red marquee light along the chain path and form a red light spot. The direct visual effect of the user or observer is that the red light spot moves in the bright area 70, that is, the marquee light effect. In this embodiment, among the multiple light spots formed by the lamp 100, the distance between the centers of any two light spots is approximately the same. Therefore, the displacement generated by each movement of the red light spot is approximately the same. Therefore, the marquee light effect is relatively smooth, uninterrupted, and unhurried, which greatly improves the marquee effect of the lamp 100.

[0029] In some embodiments, each lamp bead 11 can emit multiple colors of light in sequence, for example, red, green, yellow, and purple in sequence. In actual application scenarios, there are four consecutive lamp beads 11 along the direction of movement of the light spot formed by the marquee light, and their colors are purple, yellow, green, and red in sequence, so that there are four colors of light spots in the bright area 70 that move and flash over and over again, one after another, to form a dazzling and colorful marquee light effect, which greatly enriches the light effect of the lamp 100. In other embodiments, the light emitting state of each lamp bead 11 can be set with reference to the setting method of the multi-color marquee effect in the previous text to obtain different light effects, and no examples are given here.

[0030] See also Figure 2 and Figure 3In this embodiment, the lamp 100 further includes a flexible circuit board 12, which is arranged along a path defined by a first straight line, a designated arc, and a second straight line. A plurality of lamp beads 11 (a plurality of first lamp beads 111 and a plurality of second lamp beads 112) are arranged in sequence and spaced apart on a side of the flexible circuit board 12 away from the center of the designated arc, so that the optical axis of the lamp beads 11 is substantially parallel to the wall surface and forms a relatively obvious bright area 70 on the wall surface, so that the bright area 70 is arranged around the periphery of the lamp 100. In this embodiment, a plurality of first lamp beads 111 in the first linear light-emitting portion 13 are arranged in sequence and spaced apart at equal intervals according to a first spacing D1, a plurality of first lamp beads 111 in the second linear light-emitting portion 14 are arranged in sequence and spaced apart at equal intervals according to a first spacing D1, and a plurality of second lamp beads 112 in the arc light-emitting portion 15 are arranged in sequence and spaced apart at equal intervals according to a second spacing D2, so that the brightness of the first linear bright area 71, the brightness of the second linear bright area 73, and the brightness of the arc bright area 72 are relatively uniform in their respective extension directions. In this embodiment, the second spacing D2 is smaller than the first spacing D1, so that the arrangement density of the second lamp beads 112 is greater than the arrangement density of the first lamp beads 111. As can be seen from the foregoing, the spacing between the centers of the two light spots formed by two adjacent first lamp beads 111 is also close to the first spacing D1, and the spacing between the centers of the two light spots formed by the two second lamp beads 112 is greater than the second spacing D2.

[0031] In this embodiment, the second spacing D2 and the first spacing D1 satisfy a certain numerical relationship, so that the spacing between the centers of the two light spots formed by the two second lamp beads 112 is close to the first spacing D1. Specifically, the centers of the multiple light spots formed by the multiple second lamp beads 112 are arranged along an arc and the arc is concentric with the designated arc. The spacing between the centers of the two light spots formed by two adjacent second lamp beads 112 is defined as the light spot spacing D3. It can be seen that the light spot spacing D3 is greater than the second spacing D2. The spacing between the center of the light spot formed by the second lamp bead 112 and the center of the designated arc is defined as the arc illumination area radius R1, and the radius of the designated arc is defined as the arc radius R2. According to the characteristics of the concentric circles, D2 = (R2 / R1) * D3, and since D3 ≈ D1, D2 ≈ (R2 / R1) * D1. In summary, in actual application scenarios, when the second spacing D2 and the first spacing D1 satisfy the numerical relationship of D2≈(R2 / R1)*D1, the spot spacing D3 between the centers of the two spots formed by two adjacent second lamp beads 112 is close to the spacing between the centers of the two spots formed by two adjacent first lamp beads 111, so that the brightness difference between the arc-shaped bright area 72 and the first linear bright area 71 and the second linear bright area 73 is small, so that the brightness of the bright area 70 formed by the lamp 100 is more uniform as a whole. Under the setting of this embodiment, the brightness of the first linear bright area 71, the brightness of the second linear bright area 73 and the brightness of the arc-shaped bright area 72 are the same.

[0032] In the present application, there is a first lamp bead 111 on the first linear light emitting portion 13 that is closest to the arc light emitting portion 15, the first lamp bead 111 adjacent to the first lamp bead 111 and the first lamp bead 111 are spaced apart from each other by D1, and the first lamp bead 111 and a second lamp bead 112 on the arc light emitting portion 15 that is closest to the first linear light emitting portion 13 are spaced apart from each other by D2, so that the first linear bright area 71 formed by the first linear light emitting portion 13 and the arc-shaped bright area 72 are better connected. There is a first lamp bead 111 on the second linear light emitting portion 14 that is closest to the arc light emitting portion 15, the first lamp bead 111 adjacent to the first lamp bead 111 and the first lamp bead 111 are spaced apart from each other by D1, and the first lamp bead 111 and a second lamp bead 112 on the arc light emitting portion 15 that is closest to the second linear light emitting portion 14 are spaced apart from each other by D2, so that the second linear bright area 73 formed by the second linear light emitting portion 14 and the arc-shaped bright area 72 are better connected.

[0033] In the present embodiment, the lamp 100 further includes a lampshade 20, which extends along a path defined by a first straight line and a second straight line of a specified arc and is arranged around the periphery of the light source module 10. Specifically, the lampshade 20 includes a first straight portion 21, a second straight portion 22 and an annular portion 23. The first straight portion 21 extends along a direction defined by the first straight line and is arranged relatively spaced apart from the first linear light-emitting portion 13. The first straight portion 21 is substantially parallel to the flexible circuit board 12 at the first linear light-emitting portion 13. The optical axis of each first lamp bead 111 on the first linear light-emitting portion 13 is substantially perpendicular to the side of the first straight portion 21 facing the first lamp bead 111, so that the light emitted by the first linear light-emitting portion 13 can be transmitted to the first straight portion 21 and penetrate the first straight portion 21 to form a first linear bright area 71 on the wall. The second straight portion 22 extends along the direction defined by the second straight line and is arranged with a relative spacing from the second linear light-emitting portion 14. The second straight portion 22 is substantially parallel to the flexible circuit board 12 at the second linear light-emitting portion 14. The optical axis of each first lamp bead 111 on the second linear light-emitting portion 14 is substantially perpendicular to the side of the second straight portion 22 facing the first lamp bead 111, so that the light emitted by the second linear light-emitting portion 14 can be transmitted to the second straight portion 22, and the second straight portion 22 is penetrated to form a second linear bright area 73 on the wall. The two ends of the annular portion 23 in the extension direction are respectively connected to the first straight portion 21 and the second straight portion 22. The annular portion 23 corresponds to the arc light-emitting portion 15 and surrounds the outer circumference of the arc light-emitting portion 15, so that the light emitted by the arc light-emitting portion 15 can be transmitted to the annular portion 23, and the annular portion 23 is penetrated to form an arc-shaped bright area 72 on the wall.

[0034] See also Figure 4In this embodiment, the lampshade 20 is provided with a plurality of texture structures 24, and the texture structures 24 include one or more structures such as saw teeth, grooves, and curved ribs. The light emitted by the lamp beads 11 is transmitted to the lampshade 20 and the texture structures 24, and is scattered on the surface of the lampshade 20 based on the texture structures 24, so that the light is distributed more evenly, and can promote the transmission of light toward two adjacent lamp beads 11, so as to fill the space between the two lamp beads 11, avoid the existence of dark areas between the light spots formed by the two lamp beads 11, or reduce the brightness difference between the dark areas and the light spots. Under the setting of this embodiment, multiple point light sources (independent lamp beads 11) cooperate with each other to form a line light source (lamp bead chain), so that the light emitted by the light source module 10 is more uniform after being transmitted through the lampshade 20, and the marquee light effect of the lamp 100 is improved. In the present embodiment, a plurality of texture structures 24 are arranged on the surface of the lampshade 20 facing the light source module 10 along the circumference of the lampshade 20 (i.e., from one end of the first straight portion 21 away from the ring-shaped portion 23 to one end of the second straight portion 22 away from the ring-shaped portion 23), and the surface here can be the outer surface of the lampshade 20 or the inner surface of the lampshade 20. The plurality of texture structures 24 are arranged along the extension direction of the lampshade 20 so that the brightness difference between the various parts of the bright area 70 is small. In the present embodiment, each texture structure 24, such as saw teeth, ribs, etc., has an extension direction, and the extension direction of the texture structure 24 is perpendicular to the arrangement direction of the plurality of lamp beads 11, so that the texture structure 24 effectively scatters light.

[0035] In this embodiment, the shape of the annular portion 23 is an arc structure, the arc defined by the annular portion 23 is cocentric with the designated arc, and the annular portion 23 and the arc light-emitting portion 15 are cocentric (coaxial) structures. In this embodiment, the spacing between each second lamp bead 112 and the arc portion 121 is the same, so that the arc-shaped bright area 72 formed by the arc light-emitting portion 15 has uniform brightness. In this embodiment, the spacing between the first linear light-emitting portion 13 and the first straight portion 21 and the spacing between the second linear light-emitting portion 14 and the second straight portion 22 are approximately the same, so that the brightness of the first linear bright area 71 and the second linear bright area 73 is approximately the same.

[0036] As can be seen from the foregoing, the spacing between the centers of the two light spots formed by two adjacent first lamp beads 111 on the lampshade 20 is close to the first spacing D1, and the spot spacing D3 between the centers of the two light spots formed by adjacent second lamp beads 112 on the wall is close to D1, the arc defined by the centers of the multiple light spots formed by multiple second lamp beads 112 on the wall, the arc defined by the centers of the multiple light spots formed by multiple second lamp beads 112 on the annular portion 23, and the designated arc are three concentric arcs from the outside to the inside. Therefore, the spacing between the centers of the two light spots formed by two adjacent second lamp beads 112 on the annular portion 23 is less than D3, that is, less than D1, and the spot density on the annular portion 23 is greater than the spot density on the first straight portion 21 (second straight portion 22). In the present application, multiple lamp beads 11 are connected in series, and the light intensity of the light emitted by the first lamp bead 111 is greater than the light intensity of the light emitted by the second lamp bead 112, so as to effectively reduce the brightness difference between the annular portion 23 and the two straight portions (the first straight portion 21 and the second straight portion 22), so that when the user looks directly at the lampshade 20, the various parts of the lampshade 20 emit light more evenly.

[0037] See also Figure 5In another embodiment, the shape of the ring-shaped portion 23 can be an arc structure, or a curved surface structure without a center of a circle. In this embodiment, the ring-shaped portion 23 does not have a structural relationship of a common center with the specified arc. In this embodiment, the portion of the flexible circuit board 12 used to arrange and set the second lamp beads 112 is defined as an arc portion 121, and the arc portion 121 extends roughly along the specified arc, and a plurality of second lamp beads 112 are arranged on the side of the arc portion 121 away from the center of the circle. The ring-shaped portion 23 is arranged around the local periphery of the arc portion 121, and each portion of the arc portion 121 in its circumferential direction is opposite to the side of the ring-shaped portion 23 facing the arc portion 121, so that most of the light emitted by the plurality of second lamp beads 112 can be transmitted to the wall via the ring-shaped portion 23. In this embodiment, the spacing between the arc portion 121 and the ring-shaped portion 23 does not remain unchanged, and the spacing between each part of the arc portion 121 and the ring-shaped portion 23 is not exactly the same. Specifically, at least two of the three positions selected on the arc portion 121 have different spacings from the annular portion 23, that is, at least two of the three second lamp beads 112 selected have different spacings from the annular portion 23. In this embodiment, the minimum spacing between the arc portion 121 and the annular portion 23 is greater than the spacing between the first linear light-emitting portion 13 and the first straight portion 21 (that is, the second linear light-emitting portion 14 and the second straight portion 22), so as to reduce the brightness of the annular portion 23 and reduce the brightness difference between the annular portion 23 and the two straight portions, so that when the user looks directly at the lampshade 20, the various parts of the lampshade 20 emit light more evenly. In this embodiment, the annular portion 23 is provided with the texture structure 24 mentioned above, and the texture structure 24 can compensate for the brightness difference caused by the difference between the spacing between one second lamp bead 112 and the annular portion 23 and the spacing between another second lamp bead 112 and the annular portion 23, so that the setting of this embodiment has little effect on the brightness uniformity of the annular portion 23.

[0038] In this embodiment, in the direction from one end of the designated arc to the midpoint of the designated arc, the spacing between the arc portion 121 and the annular portion 23 gradually increases, reflecting that the annular portion 23 in this embodiment roughly passes through the center of the designated arc relative to the extension direction of the light source module 10, avoiding the annular portion 23 from being tilted toward one side of the first linear light-emitting portion 13 or toward one side of the second linear light-emitting portion 14, so that the shape of the lamp 100 is roughly a symmetrical structure, and the bright area 70 formed by the lamp 100 on the wall is also roughly symmetrical, thereby enhancing the beauty of the lamp 100 and the light effect. As an example, the center angle of the arc portion 121 is 180°, the annular portion 23 is an arc structure with a center angle of 180°, the annular portion 23 is spaced from the center of the arc portion 121, and the annular portion 23 and the arc portion 121 are symmetrically arranged about the axis connecting the centers of the two.

In this embodiment, the reflector 30 is a flat long strip structure, and the reflector 30 and the flexible circuit board 12 of the first linear light-emitting portion 13 are arranged at an angle, such as approximately vertically, or in the direction in which the first linear light-emitting portion 13 points to the first straight line portion 21, the distance between the reflector 30 and the optical axis of the first lamp bead 111 gradually increases.

The light of each first lamp bead 111 can be transmitted to one end of a corresponding reflective surface 31. Under the reflection effect of the end of the reflective surface 31, the light is transmitted toward the space on both sides of the optical axis of the first lamp bead 111 and transmitted to the first straight portion 21, so as to improve the brightness of the portion corresponding to the gap between the first straight portion 21 and the two adjacent first lamp beads 111, so that the brightness on the first straight portion 21 is more uniform. Please refer to Fig. 9In other embodiments, the reflective surface 31 is a convex surface, and the multiple convex surfaces correspond to the multiple first lamp beads 111 one by one and are arranged relatively.

Under the setting of this embodiment, the reflective member 30 reduces the loss of light, improves the brightness of the first straight portion 21, reduces the brightness difference between the first straight portion 21 and the ring portion 23, and makes the lampshade 20 emit light uniformly as a whole.

[0041] In the present embodiment, the lamp 100 further includes a reflector 30, which is disposed on the light-emitting side of the second linear light-emitting portion 14, and extends in the direction defined by the second straight line. Specifically, the reflector 30 is disposed between the second linear light-emitting portion 14 and the second straight line portion 22, and extends in the direction defined by the second straight line, so that the structure of the reflector 30 adapts to the spatial form between the light source module 10 and the lampshade 20. In the present embodiment, the reflector 30 is a flat long strip structure, and the reflector 30 and the flexible circuit board 12 of the second linear light-emitting portion 14 are arranged at an angle, such as being approximately vertically arranged, or in the direction in which the second linear light-emitting portion 14 points to the second straight line portion 22, the distance between the reflector 30 and the optical axis of the first lamp bead 111 gradually increases. A plurality of reflective surfaces 31 are provided on one side of the reflector 30 facing the second linear light emitting portion 14. The plurality of reflective surfaces 31 are arranged in sequence along the direction defined by the second straight line. Two adjacent reflective surfaces 31 are connected. The plurality of reflective surfaces 31 are located on the optical path of the light emitted by the second linear light emitting portion 14. The light is reflected by the plurality of reflective surfaces 31 and transmitted toward the second linear portion 22 to reduce the loss of light and improve the brightness of the second linear portion 22. In some embodiments, two reflective elements 30 may be provided between the second linear light emitting portion 14 and the second linear portion 22. The two reflective elements 30 are arranged at a relative interval and are respectively located on the left and right sides of the second linear light emitting portion 14 in the direction defined by the second straight line to further reduce the loss of light.

[0042] In this embodiment, the reflective surface 31 is a concave surface, and each two adjacent first lamp beads 111 correspond to a reflective surface 31. The two ends of the reflective surface 31 in the direction defined by the second straight line are respectively opposite to the two adjacent first lamp beads 111. The light of each first lamp bead 111 can be transmitted to one end of a corresponding reflective surface 31, and the light is reflected by the end of the reflective surface 31 toward the space on both sides of the optical axis of the first lamp bead 111 and transmitted to the second straight portion 22, so as to increase the brightness of the part corresponding to the gap between the second straight portion 22 and the two adjacent first lamp beads 111, so that the brightness on the second straight portion 22 is more uniform.

In this embodiment, at least one support shell 40 is provided with an installation structure such as a surrounding convex block structure for installing a flexible circuit board 12, so that the light source module 10 is connected to at least one support shell 40 to ensure the stability of the structure of the light source module 10, so that the lamp 100 emits light stably. The reflector 30 is connected to the side wall of the support shell 40 and is arranged toward the light source module 10. The lampshade 20 is arranged between the two support shells 40 and is respectively connected to the two support shells 40, such as threaded connection, embedded fit, etc. The lampshade 20 is arranged around the outer periphery of the installation space 41 to close the installation space 41, reduce water vapor and dust from entering the installation space 41, extend the service life of the light source module 10, prevent dust from adhering to the lamp beads 11, and ensure the lighting effect of the lamp 100. In this embodiment, the supporting shell 40 is a light-proof structure, so that the light emitted by the light source module 10 is basically emitted from the lampshade 20 and transmitted to the wall, so that the bright area 70 formed by the lamp 100 is surrounded by the periphery of the lamp 100, and the loss of light is reduced, thereby improving the brightness of the bright area 70.

[0045] In this embodiment, a lamp 100 may include two light source modules 10, the first linear light emitting portion 13 and the second linear light emitting portion 14 in each light source module 10 are arranged in parallel, the light source module 10 has a first end and a second end in a direction defined by a first straight line (or a second straight line), the arc light emitting portion 15 of each light source module 10 is located at the first end of each light source module 10, the second ends of the two second light source modules 10 are connected, and the two light source modules 10 are electrically connected. Specifically, the first linear light emitting portions 13 of the two light source modules 10 are both extended and connected along the first straight line, and the second linear light emitting portions 14 of the two light source modules 10 are both extended and connected along the second straight line, so that the entire periphery of the lamp 100 can emit light continuously.

[0046] See also Figure 1 and Figure 2 In this embodiment, the lamp 100 includes two light-emitting units 60, and the two light-emitting units 60 are spliced ​​to form a lighting device capable of emitting light all around. Fig.10Specifically, each light-emitting unit 60 includes a light source module 10, a lampshade 20 and two supporting shells 40 as described above. The light source module 10 in each light-emitting unit 60 is arranged in an installation space 41 defined by the two supporting shells 40 of the light-emitting unit 60, and the lampshade 20 is arranged around the partial periphery of the installation space 41, so that the light-emitting unit 60 is generally in a closed structure. The light-emitting unit 60 also includes at least two reflectors 30, and the two reflectors 30 are respectively arranged between the first linear light-emitting portion 13 and the first straight portion 21 and between the second linear light-emitting portion 14 and the second straight portion 22. In this embodiment, the lamp 100 also includes an electrical connector 50 and an electrical matching member (not shown in the figure), and the electrical connector 50 and the electrical matching member are respectively arranged in the two light-emitting units 60. The electrical connector 50 is an embedded structure, and the electrical connector 50 may include a probe, etc. The electrical connector 50 is connected to a supporting shell 40 (integrally formed, threaded, etc.) of a corresponding light-emitting unit 60. The electrical connector 50 is located at one end of the light-emitting unit 60 away from the arc light-emitting portion 15. The electrical connector 50 is electrically connected to the first linear light-emitting portion 13 and the second linear light-emitting portion 14 to form a circuit. Correspondingly, the supporting shell 40 of the light-emitting unit 60 provided with the electrical matching component is partially recessed and forms a groove body (not shown in the figure). The groove body is located at one end of the light-emitting unit 60 away from the arc light-emitting portion 15. The electrical matching component may include a conductive structure such as a metal sheet. The electrical matching component is arranged in the groove body and is electrically connected to the first linear light-emitting portion 13 and the second linear light-emitting portion 14 of the light-emitting unit 60 to form a circuit. In an actual application scenario, the electrical connector 50 on one light-emitting unit 60 is embedded in a groove on another light-emitting unit 60 and abuts against an electrical matching part to achieve electrical connection, so that the two light source modules 10 are electrically connected. The two light source modules 10 form a complete surrounding lamp bead chain, so that the bright area 70 formed by the lamp 100 on the wall is a complete halo, thereby improving the display effect of the lamp 100.

[0047] When the electrical connector 50 is in cooperation with the electrical matching component, the first straight portions 21 of the lampshades 20 of the two light-emitting units 60 abut against each other and are located in the same plane, and the second straight portions 22 of the two second lampshades 20 abut against each other and are located in the same plane, so that the structure formed by the two lampshades 20 is a complete ring body and is arranged around the outer periphery of the two light source modules 10, so that the lamp 100 emits light in a surrounding manner, thereby improving the visual effect of the lamp 100.

[0048] The lamp 100 provided in this embodiment includes a light source module 10, and the light source module 10 has a first linear light emitting portion 13 extending in the direction where the first straight line is located, a second linear light emitting portion 14 extending in the direction where the second straight line is located, and an arc light emitting portion 15 extending in the direction where the specified arc is located, and the two ends of the arc light emitting portion 15 are respectively connected to the first linear light emitting portion 13 and the second linear light emitting portion 14, so that the lamp 100 has a first linear bright area 71, a second linear bright area 73 and an arc bright area 72, thereby improving the richness of the lighting effect of the lamp 100. The lamp 100 includes a plurality of first lamp beads 111 and a plurality of second lamp beads 112, some of the first lamp beads 111 are sequentially arranged in the first linear light emitting portion 13 along the direction where the first straight line is located, and some of the first lamp beads 111 are sequentially arranged in the second linear light emitting portion 14 along the direction where the second straight line is located, and a plurality of second lamp beads 112 are sequentially arranged in the arc light emitting portion 15 along the direction where the specified arc is located. In the present embodiment, the light emitted by two adjacent first lamp beads 111 is approximately parallel, and the spacing between the centers of two light spots formed on the wall by the two first lamp beads 111 is approximately the same as the spacing between the two first lamp beads 111; the light emitted by two adjacent second lamp beads 112 gradually moves away from each other during the transmission process, and the spacing between the centers of two light spots formed on the wall by the two second lamp beads 112 is greater than the spacing between the two second lamp beads 112. Therefore, in the present embodiment, the arrangement density of the multiple first lamp beads 111 is set to be smaller than the arrangement density of the second lamp beads 112, that is, the spacing between the two first lamp beads 111 is set to be smaller than the spacing between the two second lamp beads 112, so that the spacing between the centers of the light spots formed by adjacent second lamp beads 112 is approximately equal to the spacing between the centers of the light spots formed by two adjacent first lamp beads 111, that is, the spacing between the centers of any two light spots among the multiple light spots formed by the lamp 100 is approximately the same.

[0049] Under the setting of this embodiment, the first straight line, the designated arc, and the second straight line define a chain path of multiple lamp beads 11, and the multiple lamp beads 11 arranged in a chain can be controlled to form a marquee effect. Specifically, the lamp 100 is provided with a normal light color, such as natural light and beige light. In actual application scenarios, the multiple lamp beads 11 on the chain path can be controlled to sequentially emit marquee light different from the normal light color and form a marquee light spot on the wall. The color of the marquee light can be red, green, etc. As an example, the color of the marquee light is red. When one of the lamp beads 11 emits red marquee light, the lamp bead 11 forms a red light spot on the wall. The red light spot replaces the white light spot or beige light spot originally formed by the lamp bead 11 on the wall. The multiple lamp beads 11 sequentially emit red marquee light along the chain path and form a red light spot. The direct visual effect of the user or observer is that the red light spot moves in the bright area 70, that is, the marquee light effect. In this embodiment, among the multiple light spots formed by the lamp 100, the distance between the centers of any two light spots is approximately the same. Therefore, the displacement generated by each movement of the red light spot is approximately the same. Therefore, the marquee light effect is relatively smooth and uninterrupted, which greatly improves the marquee effect of the lamp 100.
