[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] See also Figure 1 , an embodiment of the present application provides a lamp 100. In this embodiment, the lamp 100 is used to provide decorative ambient light, for example, for emitting light to a light receiving surface. The lamp 100 can be a wall washer lamp or an ambient light. The light receiving surface can be a ceiling, a wall, a floor, etc. As an example, the lamp 100 is a wall washer lamp, which is used to provide decorative light for the ceiling. As just an example, the lamp 100 is installed on the wall, and by adjusting the installation angle of the lamp 100, the outgoing light of the lamp can be projected onto the ceiling, forming a rectangular light spot on the ceiling.

[0032] See 1 and Figure 2In one embodiment provided in the present application, a lamp 100 includes a mounting base 10 and a plurality of light-emitting modules 20, which are arranged in sequence on the mounting base 10. Each light-emitting module 20 includes a light-emitting unit 21 and an optical lens 23. The light-emitting unit 21 is connected to the mounting base 10. The colors of the emitted light formed by the light-emitting units 21 in the plurality of light-emitting modules 20 are different. The optical lenses 23 are sequentially arranged on the emitted light path formed by the light-emitting units 21. Each light-emitting module 20 has a beam shaping portion 24, which is arranged on the side of the optical lens 23 away from the light-emitting unit 21. The beam shaping portion 24 includes an optical structure 241, which is used to shape the emitted light of the light-emitting unit 21 to obtain a rectangular light spot. The emitted light of the light-emitting unit 21 transmits the corresponding optical structure 241 and is emitted to the light receiving surface to form a plurality of rectangular light spots corresponding to each other. The plurality of rectangular light spots formed by the plurality of light-emitting modules 20 are arranged in sequence. By arranging multiple light-emitting modules 20 to collectively project light toward the light-receiving surface, multiple corresponding light spots can be formed, thereby improving the brightness and range of the light output of the lamp 100 and enriching the decorative light effect. In this embodiment, each light-emitting module 20 includes an optical lens 23 and a beam shaping unit 24. The beam shaping unit 24 is arranged in the optical path of the outgoing light. By arranging the optical lens 23 and the beam shaping unit 24, the light spot can be shaped into a rectangular light spot. The rectangular light spot can match the length and width of a narrow rectangular area such as a ceiling. The multiple rectangular light spots corresponding to the multiple light-emitting modules 20 are arranged in sequence to form an orderly arrangement, which can enhance the decorative effect of the decorative light. This improves the decorative effect of the decorative light. Next, the various components of the lamp 100 and the specific structure of each component will be introduced one by one.

[0033] See also Figure 2 and Figure 3 In this embodiment, the mounting base 10 serves as a mounting carrier of the lamp 100, which is used to mount a plurality of light-emitting modules 20 and fix the lamp 100 on a mounting platform. The mounting platform can be a wall, a ceiling, or other brackets. The mounting base 10 has a first end 101 and a second end 102, and the first end 101 and the second end 102 are opposite to each other. The mounting base 10 has an extension direction X pointing from the first end 101 to the second end 102, and the plurality of light-emitting modules 20 are arranged in sequence along the extension direction X between the first end 101 and the second end 102, so that the plurality of light-emitting modules 20 can simultaneously project light to the light receiving surface to increase the light brightness and light range.

[0034] In this embodiment, there is no specific restriction on the number of light-emitting modules 20. It is understandable that the more light-emitting modules 20 there are, the more rectangular light spots will be formed. Specifically, in this embodiment, the lamp 100 can be installed on a wall when in use and cast light on the ceiling. In the direction of gravity, the installation position of the first end 101 is higher than the installation position of the second end 102, and there is a height difference between the first end 101 and the second end 102. The mounting base 10 includes a plurality of mounting plates 11 arranged in sequence between the first end 101 and the second end 102, and the plurality of mounting plates 11 are arranged according to a specified arc trajectory. For example, each mounting plate 11 is arranged along the tangent direction of the arc, and there is a certain angle between the planes where adjacent mounting plates 11 are located. The center of the arc is set on the side of the mounting base 10 away from the light receiving surface, so that the plurality of mounting plates 11 are arranged to form an arc surface convex toward the light receiving surface. Multiple light-emitting modules 20 are sequentially arranged on multiple mounting plates 11 and are located on the side of the mounting plate 11 away from the center of the circle. Since there is a certain angle between the planes where adjacent mounting plates 11 are located, adjacent light-emitting modules 20 are staggered with each other, which can reduce the overlap rate between adjacent rectangular light spots formed by adjacent light-emitting modules 20 on the light receiving surface and improve the clarity of each rectangular light spot.

[0035] In other embodiments, the mounting base 10 may also be a flat plate structure, which is mounted on a wall and projects light onto the ceiling. The mounting base 10 with a flat plate structure may extend from the first end 101 to the second end 102. In the direction of gravity, the mounting position of the first end 101 is higher than the mounting position of the second end 102, and there is a height difference between the first end 101 and the second end 102. A plurality of light-emitting modules 20 are sequentially arranged between the first end 101 and the second end 102, and are arranged toward the light-receiving surface so as to collectively project light onto the light-receiving surface. At this time, the normals of the plurality of light-emitting modules 20 may be substantially parallel to each other, and the plurality of light-emitting modules 20 may form a light effect in which a plurality of rectangular light spots are arranged in correspondence.

[0036] See also Figure 4It should be noted that the light spot area c formed by the multiple light-emitting modules 20 in any of the above embodiments includes multiple rectangular light spots c1. Each rectangular light spot c1 is formed by projection from a corresponding light-emitting module 20. The rectangular light spots c1 have a light spot width direction f and a light spot length direction e. The light spot width direction f is approximately perpendicular to the light spot length direction e. For example, the light spot length is three times or more the light spot width. Adjacent rectangular light spots c1 are arranged consecutively on the light-receiving surface, arranged in sequence along the light spot width direction f. The long sides of two adjacent rectangular light spots c1 are adjacent to or overlap each other. When the colors of the light emitted by each light-emitting module 20 are different, a continuous rainbow lighting effect can be formed on the light-receiving surface. In this embodiment, the spacing between adjacent light-emitting modules 20 can be adjusted to minimize the overlap between adjacent rectangular light spots c1. This reduces the overlap and crosstalk between the rectangular light spots c1 formed by different light-emitting modules 20, ensures the clarity of each rectangular light spot c1, and enhances the user's visual experience. As an example, a plurality of light-emitting modules 20 are arranged adjacent to each other in sequence to form a row so that a plurality of rectangular light spots c1 corresponding to the plurality of light-emitting modules 20 are adjacent to each other in sequence, so that a plurality of rectangular light spots c1 are arranged in sequence. For reference only, the spacing between two adjacent light-emitting modules 20 can be greater than or equal to 5 cm and less than or equal to 15 cm. For example, the spacing between two adjacent light-emitting modules 20 can be 5 cm. It can be understood that the spacing between two adjacent light-emitting modules 20 can also be other values, and this embodiment does not impose specific restrictions on this. When two adjacent rectangular light spots c1 overlap, the overlapping area ratio is greater than 0 and less than or equal to 10%. For example, the overlapping area ratio can be 2%, 5%, or other values, and this embodiment does not impose specific restrictions on this. "Overlapping area ratio" can be understood as the degree of overlap between two adjacent rectangular light spots c1, specifically the ratio of the overlapping area to the sum of the areas of the two adjacent rectangular light spots c1.

[0037] Please refer again Figure 2 and Figure 5In this embodiment, each light-emitting module 20 includes a light-emitting unit 21, which is detachably mounted on the mounting base 10 to facilitate maintenance and replacement of the light-emitting unit 21. The light-emitting unit 21 has a light-emitting side, which is away from the mounting base 10 and is arranged toward the light-receiving surface for emitting light to the light-receiving surface. In this embodiment, the light-emitting unit 21 is an incoherent light source, which can specifically be a multi-color chip integrated lamp bead, a plurality of single-color lamp beads tightly patched, or other multi-color LED lamp beads, so that the multiple light-emitting modules 20 can emit outgoing light of different colors, thereby forming a rainbow-like light spot effect on the light-receiving surface. As an example, the light-emitting unit 21 is a multi-color chip integrated LED lamp bead. The encapsulation shell of each light-emitting unit 21 includes a plurality of LED chips of different colors. When the light-emitting unit 21 is in use, the LED chips of different colors can be lit separately or simultaneously to form outgoing light of different colors. For example, when LED chips of different colors are turned on in the same light-emitting unit 21, they can emit yellow, green, red, or other colors of light, creating a flowing color change effect and increasing visual appeal. The color of the light emitted by each light-emitting unit 21 can be controlled according to actual usage needs to create a rainbow light effect.

[0038] As another example, the light-emitting unit 21 comprises multiple single-color LEDs. Specifically, multiple single-color LEDs are closely arranged on a substrate, each of which can be independently controlled to control the color of the light ultimately emitted by the light-emitting unit 21. For example, each LED can emit only a specific light source: one emits only red light, and another emits only blue light. When the light-emitting unit 21 needs to emit blue light, the blue-emitting LED is activated, while the other LEDs are deactivated. Furthermore, in some embodiments, when at least two LEDs at different distances are illuminated simultaneously, the resulting at least two different colors of emitted light can mix to create a new color, further enhancing the richness of the decorative light. For example, when red and blue light mix, they can create purple light, enriching the color of the decorative light and creating a variety of different light spots. In this embodiment, the different colored LEDs in each light-emitting unit 21 can be controlled to operate, allowing each light source 21 to produce a different, distinct light source. When the lights emitted by the LEDs in multiple light-emitting modules 20 differ in color, a rainbow light effect can be created, enriching the visual experience.

[0039] In other embodiments, the light-emitting unit 21 may also be a monochrome lamp bead. The colors of the emitted light formed by the monochrome lamp beads in multiple light-emitting modules 20 are different. When multiple light-emitting modules 20 project light to the light receiving surface at the same time, different colored light spots can be formed to enhance visual appeal.

[0040] See also Figure 5 and Figure 6In this embodiment, in order to improve the uniformity of the emitted light formed by the multi-color lamp beads, each light emitting module 20 may further include a light mixing element 22. When the multiple light emitting units 21 in each light emitting module 20 form excellent light of multiple colors, the light mixing element 22 is used to mix the light. The light mixing element 22 is set on the corresponding optical lens 23 and the light-emitting side of the corresponding light-emitting unit 21, and is located on the outgoing light path of the corresponding light-emitting unit 21. Specifically, when the light-emitting unit 21 is a close-patch structure of multiple single-color packaged lamp beads, and multiple single-color lamp beads are lit at the same time, the light-emitting unit 21 can form outgoing light of different colors, and the outgoing light passes through the light-mixing component 22 for sufficient light mixing, so that the color distribution of the mixed light is more uniform, thereby avoiding the color separation of the outgoing light. The light-mixing component 22 can be specifically arranged in the accommodating space 231 of the optical lens 23, and each light-mixing component 22 also has an accommodating groove (not shown in the figure), and the accommodating groove is arranged on the side facing the corresponding light-emitting unit 21. Specifically, the inner wall of the light-mixing component 22 defines the accommodating groove, and the light-emitting unit 21 is arranged in the accommodating groove. Specifically, the light-mixing component 22 can be a bowl-shaped structure, which can be buckled on the light-emitting unit 21, so as to fully mix the outgoing light of the light-emitting unit 21. The light emitted from the light emitting unit 21 is transmitted to the light mixing element 22 , which can improve the utilization rate of the emitted light to a certain extent, and can also protect the light emitting unit 21 .

[0041] See also Figure 2 In this embodiment, the lamp 100 further includes a circuit board 30, which is used to provide electrical energy to the multiple light-emitting modules 20 and achieve internal and external conduction between the light-emitting modules 20 and the external circuit. The circuit board 30 is also used to control the color of the light generated by each light-emitting unit 21. Specifically, the circuit board 30 can be a flexible circuit board 30 that can be bent, folded, and curled at will to adapt to different assembly conditions. The circuit board 30 can also be a rigid circuit board 30, which is generally flat and mounted on the mounting base 10, with each light-emitting module 20 disposed on the circuit board 30.

[0042] The circuit board 30 may be provided with a power module 31. The number of power modules 31 may be one or more. As an example, there is one power module 31, which is simultaneously connected to multiple light-emitting modules 20 and provides power to the multiple light-emitting modules 20. As another example, there are multiple power modules 31, and multiple power modules 31 are connected to the multiple light-emitting modules 20 to independently control the power supply to the multiple light-emitting modules 20.

[0043] A control unit 32 may be provided on the circuit board 30, and the control unit 32 may be a control chip. The number of control units 32 may be one, and one control unit 32 is simultaneously connected to the light-emitting units 21 in multiple light-emitting modules 20, and simultaneously controls the multiple light-emitting units 21 to work separately. As another example, the number of control units 32 may be multiple, and multiple control units 32 and the light-emitting units 21 in multiple light-emitting modules 20 are respectively connected one-to-one, so as to realize single-point control and improve the working stability and reliability of the lamp 100. Specifically, multiple control units 32 can independently control the luminous brightness, flashing frequency, light color, light emission time, etc. of the corresponding light-emitting units 21, so that the working parameters of each light-emitting module 20 do not interfere with each other, thereby forming a variety of decorative light effects.

[0044] Please refer again Figure 2 and Figure 6 In this embodiment, each light-emitting module 20 further includes an optical lens 23. The optical lens 23 can be a convex lens or a total internal reflection lens (TIR). In this embodiment, the optical lens 23 is a total internal reflection lens, which can effectively improve the utilization rate of light. The optical lens 23 is arranged on the outgoing light path formed by the corresponding light-emitting unit 21. The optical lens 23 is used to transmit the outgoing light of the light-emitting unit 21 to the beam shaping part 24. Specifically, each optical lens 23 is detachably connected to the mounting seat 10. The optical lens 23 is provided with a receiving space on the side facing the corresponding light-emitting unit 21, and the light-emitting unit 21 is arranged in the receiving space. The optical lens 23 may include a light-emitting surface 232. The light-emitting surface 232 is arranged on the side away from the light-emitting unit 21. The light emitted from the light-emitting unit 21 at any angle is transmitted through the light-emitting surface 232 and then propagates to the beam shaping part 24, which can improve the utilization rate of light.

[0045] See also Figure 3 In this embodiment, each optical lens 23 has an optical axis O1. Because the multiple mounting plates 11 of the mounting base 10 are arranged along a predetermined arc between the first end 101 and the second end 102, which have a height difference, the multiple rectangular light spots c1 correspondingly formed on the light-receiving surface of the multiple light-emitting modules 20 are also arranged along the extension direction of the circular arc. The optical axes O1 of the multiple optical lenses 23 are arranged substantially perpendicular to the tangent direction of the circular arc. An optical axis angle a exists between the optical axes O1 of each adjacent light-emitting module 20. The value of the optical axis angle a can range from 5° to 25° (inclusive).

[0046] Specifically, in this embodiment, a plurality of adjacent light-emitting modules 20 are arranged to form a plurality of optical axis angles a. Since there is a height difference between the first end 101 and the second end 102 of the mounting base 10, and the first end 101 and the second end 102 are arranged on an arc trajectory, the plurality of optical axis angles a gradually decrease along the extending direction X from the first end 101 to the second end 102. For example, the plurality of light-emitting modules 20 include a leading light-emitting module 201 and a trailing light-emitting module 202. The leading light-emitting module 201 is arranged at the first end 101, the trailing light-emitting module 202 is arranged at the second end 102, and the remaining light-emitting modules 20 are arranged between the leading light-emitting module 201 and the trailing light-emitting module 202. The optical axis angle a between the head-end light-emitting module 201 and the adjacent light-emitting module 20 can be 21°, the optical axis angle a between the tail-end light-emitting module 202 and the adjacent light-emitting module 20 can be 9°, and the optical axis angles a between the remaining plurality of sequentially arranged light-emitting modules 20 can be 17°, 12°, and so on. This reduces the overlap area between the plurality of rectangular light spots c1 formed by the plurality of light-emitting modules 20, thereby improving the clarity of each rectangular light spot. It should be noted that the optical axis angle a can also have other value ranges, and different optical axis angles a between two adjacent light-emitting modules will produce different decorative light effects.

[0047] See also Figure 3 and Figure 4 In this embodiment, in the direction of gravity, because the installation height of the first end 101 is higher than that of the second end 102, when the light-receiving surface is a ceiling, the distance between the head-end light-receiving module 201 and the light-receiving surface is the shortest, resulting in the highest brightness and the clearest light spot. At the same time, the optical axis angle a between the head-end light-receiving module 201 and the adjacent light-receiving module 20 is the largest, so that light from the head-end light-receiving module 201 is projected to the ceiling via a shorter path, and the corresponding rectangular light spot c1 has the smallest spot width. Meanwhile, the tail-end light-receiving module 202 is the longest distance from the light-receiving surface, and the optical axis angle a between the tail-end light-receiving module 202 and the adjacent light-receiving module 20 is the smallest, allowing it to project light to the farthest end of the light-receiving surface, forming the rectangular light spot c1. The corresponding rectangular light spot c1 has the largest spot width. The distance between the multiple light-emitting modules 20 arranged between the head-end light-emitting module 201 and the tail-end light-emitting module 202 and the light receiving surface gradually increases, and the optical axis angle a between two adjacent light-emitting modules 20 also gradually decreases. The width of the corresponding multiple rectangular light spots c1 gradually and evenly increases, which can improve the layering of the decorative light.

[0048] In this embodiment, the outgoing light of each light-emitting module 20 has a set beam angle d after passing through the optical lens 23. Since the value range of the beam angle d can be 10° to 25° (including the end points). As an example, the multiple beam angles formed by the multiple light-emitting modules 20 decrease successively along the extension direction X from the first end 101 to the second end 102. The optical axis angle a between the head-end light-emitting module 201 and the adjacent light-emitting module 20 is the largest, and the beam angle d of the head-end light-emitting module 201 is the largest. The optical axis angle a between the tail-end light-emitting module 202 and the adjacent light-emitting module 20 is the smallest, and the corresponding beam angle d of the tail-end light-emitting module 202 is the smallest, which can form a rectangular light spot c1 with a larger light spot width at the far end of the ceiling. Similarly, as the distance between the light-emitting modules 20 arranged between the leading light-emitting module 201 and the trailing light-emitting module 202 and the light-receiving surface gradually increases along the arrangement direction, the angle a between the optical axes of two adjacent light-emitting modules 20 gradually decreases along the extension direction, resulting in the multiple beam angles d formed by the multiple light-emitting modules 20 gradually decreasing along the extension direction. By providing the aforementioned mounting base 10, the width of the rectangular light spots c1 formed by the multiple light-emitting modules 20 can be gradually increased, creating a decorative effect with distinct layering and enhancing the visual experience.

[0049] In some embodiments, because the multiple light-emitting modules 20 are installed at increasingly greater distances from the ceiling, the brightness of the corresponding multiple rectangular light spots c1 on the ceiling is unevenly distributed. To achieve a more uniform and clearer light output, the rated power of the light-emitting units 21 in the multiple light-emitting modules 20 can be increased in sequence along the extension direction X from the first end 101 to the second end 102. This can compensate for the dimming of the rectangular light spots c1 as they become farther away, thereby creating a more uniform and clearer light output. Specifically, in the extension direction X from the first end 101 to the second end 102, the rated powers of the light-emitting units 21 in the multiple light-emitting modules 20 increase successively, so that the light-emitting unit 21 with the lowest rated power corresponds to the head-end light-emitting module 201, and the light-emitting unit 21 with the highest rated power corresponds to the tail-end light-emitting module 202. The rated powers of the light-emitting units 21 of the multiple light-emitting modules 20 arranged between the head-end light-emitting module 201 and the tail-end light-emitting module 202 gradually increase, so that the brightness of the multiple rectangular light spots c1 can be adjusted to be approximately the same.

[0050] See also Figure 2 and Figure 5In this embodiment, the outgoing light of each light-emitting module 20 forms a rectangular light spot c1 on the light receiving surface after passing through the optical lens 23 and the beam shaping unit 24. Specifically, the beam shaping unit 24 is arranged on the outgoing light path of the corresponding light-emitting module 20 and is located on the side of the optical lens 23 away from the light-emitting unit 21. The beam shaping unit 24 can be a light-transmitting structure such as a lens or a light-transmitting plate. The beam shaping unit 24 is used to change the propagation shape of the light, for example, changing the light from a circular shape to a rectangular shape to form a rectangular light spot c1. In this embodiment, the outgoing light can form a circular light spot or a light spot of other shapes after passing through the optical lens 23, and the beam shaping unit 24 can stretch the circular light spot or the light spot of other shapes to form a rectangular light spot c1. More specifically, the beam shaping unit 24 includes an optical structure 241. The optical structure 241 can be arranged on the surface or inside the beam shaping unit 24. The optical structure 241 is used to shape the outgoing light of the light-emitting unit 21 and obtain a more uniform outgoing light. The optical structure 241 includes a plurality of stripes 2411, each of which extends along the extension direction X from the first end 101 to the second end 102 of the mounting base, and is used to stretch a circular or irregular light spot into a rectangular light spot c1. Specifically, the shape of the rectangular light spot c1 in the light spot width direction f is stretched into a straight line. The plurality of stripes 2411 are also arranged in sequence along a reference direction Y, which is perpendicular to the extension direction X. By arranging the plurality of stripes 2411 in the reference direction Y, the rectangular light spot c1 can be stretched into a straight line in the light spot length direction e, thereby forming a rectangular light spot c1, which can correspond to the narrow and long shape of the ceiling and enhance the decorative effect. It should be noted that the total length of the plurality of stripes 2411 in the reference direction Y can be adjusted by adjusting the number of stripes 2411, thereby controlling the spot length of the corresponding rectangular light spot c1, and forming a variety of different arrangement light effects.

[0051] In this embodiment, the stripes 2411 can include at least one of the following structures: a linear stripe structure, a wavy stripe structure, or a sawtooth stripe structure. As an example, multiple linear stripe structures are evenly spaced on the surface of the beam shaping section 24, forming a rectangular stripe plate. When the outgoing light reaches the beam shaping section 24, it is evenly diverged at the stripe plate, forming a uniformly mixed rectangular light spot c1.

[0052] For ease of installation and use, the beam shaping unit 24 can be positioned adjacent to the optical lens 23 or spaced apart from it. Specifically, the optical lens 23 and the beam shaping unit 24 are sequentially arranged on the outgoing light path of the light-emitting unit 21, with the light-emitting surface 232 of the optical lens 23 facing the beam shaping unit 24. Because multiple light-emitting modules 20 are arranged on the mounting base 10 and positioned between the first end 101 and the second end 102, the beam shaping unit 24 is also arranged along the first end 101 toward the second end 102, ensuring that the outgoing light from any light-emitting module 20 can transmit through the beam shaping unit 24 and propagate to the light-receiving surface, forming a uniform rectangular light spot c1.

[0053] See also Figure 6 As an example, the beam shaping unit 24 and the light emitting surface 232 are spaced apart, which facilitates installation and replacement; on the other hand, it prevents heat from being directly transferred to the beam shaping unit 24, thereby increasing the service life of the beam shaping unit 24. Figure 7 and Figure 8 As another example, the beam shaping unit 24 is positioned adjacent to the light-emitting surface 232 to minimize light loss during propagation and improve light efficiency. Furthermore, this reduces the overall size of the lamp 100, improving its compactness and portability.

[0054] See also Figure 7 and Figure 9 In this embodiment, the areas of the light emitting surfaces 232 of the plurality of light emitting modules 20 may be the same or different, and this embodiment does not impose any specific limitation on this.

[0055] See also Figure 5 In some embodiments, two adjacent beam shaping parts 24 can be integrally molded and connected. Specifically, the beam shaping part 24 has an exit surface 242 for light emission. The beam shaping parts 24 of the plurality of light-emitting modules 20 are arranged in sequence along the extension direction X. Adjacent beam shaping parts 24 can be injection molded or adhesively molded, so that the adjacent beam shaping parts 24 are continuously connected, which can provide a more continuous beam shaping effect and achieve a smoother beam distribution. The areas of the exit surfaces 242 of the plurality of beam shaping parts 24 can be the same or can increase in sequence along the extension direction X. This embodiment does not impose any specific restrictions on this. Please refer to Figure 7In some embodiments, adjacent beam shaping sections 24 can be spaced apart, allowing for more flexible adjustment of the position and angle of each beam shaping section 24 to create a variety of decorative light effects. Specifically, the beam shaping sections 24 of the multiple light-emitting modules 20 are sequentially arranged along the extension direction X, with a space between adjacent beam shaping sections 24. Similarly, the areas of the exit surfaces 242 of the multiple beam shaping sections 24 can be the same or different. Specifically, the areas of the exit surfaces 242 of the multiple beam shaping sections 24 can increase sequentially along the extension direction X.

[0056] As just one example, the optical lenses 23 in multiple light-emitting modules 20 are of the same size, resulting in the same light-emitting surface 232 for each light-emitting module 20. Light-emitting surfaces 232 of the same area can simplify the design and manufacturing process, thereby reducing costs and improving production efficiency. Furthermore, optical lenses 23 having the same light-emitting surface 232 area can ensure that the light generated by each optical lens 23 has similar quality characteristics, such as spot shape and light uniformity.

[0057] As another example, the areas of the light-emitting surfaces 232 of the multiple light-emitting modules 20 increase sequentially along the direction extending from the first end 101 to the second end 102 of the mounting base 10. That is, the sizes of the optical lenses 23 in the multiple light-emitting modules 20 increase sequentially along the direction extending, thereby achieving a wider light-emitting range. It is understood that, in another example, the areas of the light-emitting surfaces 232 of the multiple light-emitting modules 20 may also decrease sequentially along the direction extending from the first end 101 to the second end 102 of the mounting base 10. When the mounting base 10 is mounted on a wall and projects light onto the ceiling, in the direction of gravity, when the installation height of the first end 101 is higher than the installation height of the second end 102, the distance between different light-emitting modules 20 and the light-receiving surface gradually increases, and the width of the corresponding rectangular light spots c1 increases. By gradually reducing the light-emitting surfaces 232 of the multiple light-emitting modules 20, the width of the multiple rectangular light spots c1 formed by the multiple light-emitting modules 20 is narrowed to approximately the same, thereby producing a more uniform decorative light.

[0058] See also Figure 8In this embodiment, to clearly differentiate the colors between adjacent rectangular light spots or improve the clarity of the light spots, the lamp 100 may further include multiple light shielding members 40. Each light shielding member 40 is disposed between the light-emitting units 21 of two adjacent light-emitting modules 20 to separate the two adjacent light-emitting modules 20. Specifically, as an example, the light shielding member 40 may be a light shielding plate. The light shielding plate may extend from the mounting base 10 and be disposed between each pair of adjacent light-emitting modules 20, thereby preventing the light emitted by the light-emitting unit 21 from propagating to the adjacent light-emitting module 20. The light shielding plate may be made of an opaque or translucent material, such as plastic, rubber, or specially treated paper. The light shielding plate forms a physical barrier that ensures that the light from each light-emitting unit 21 is confined to its predetermined range, thereby preventing light from interfering with light from adjacent light-emitting modules 20, reducing the overlap area between adjacent rectangular light spots c1, and ensuring the clarity of the adjacent rectangular light spots c1. In other embodiments, each light shielding plate may also be disposed around the periphery of each light-emitting module 20.

[0059] In summary, the present application provides a lamp 100 in an embodiment for illuminating a light receiving surface. The lamp 100 includes a mounting base 10 and a plurality of light-emitting modules 20. The plurality of light-emitting modules 20 are arranged on the mounting base 10 and project light toward the light receiving surface, thereby forming a plurality of corresponding light spots, thereby improving the light output brightness and light output range of the lamp 100 and enriching the effect of the decorative light. In this embodiment, each light-emitting module 20 includes an optical lens 23 and a beam shaping portion 24. The beam shaping portion 24 is arranged on the optical path of the outgoing light. By arranging the optical lens 23 and the beam shaping portion 24, the light spot can be shaped to form a rectangular light spot c1. The rectangular light spot c1 can match the length and width of a narrow rectangular area such as a ceiling, and the plurality of rectangular light spots c1 corresponding to the plurality of light-emitting modules 20 are arranged in sequence to form an orderly arrangement, which can improve the decorative effect of the decorative light.
