Description

Technical Field

[0001] The present application relates to the field of lighting fixtures, and in particular to a lamp. Background Art

[0002] With the continuous advancement and development of modern lighting, spatial illumination has become an essential component, leading to diverse requirements for lighting configurations from consumers and designers. Lamps often feature multiple light-emitting units, each of which simultaneously projects light onto a light-receiving surface, creating multiple light spots. Lampshades are typically positioned outside these units to protect them. Consequently, light from these units passes through the lampshade to the light-receiving surface. However, due to the obstruction of the lampshade and the distance between the light-emitting units and the light-receiving surface, the light emitted by these units experiences significant attenuation, resulting in dim brightness and low light output efficiency for the entire lamp.

[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. In this embodiment, the lamp 100 is a wall washer lamp, which is used to provide decorative light for the ceiling. Specifically, 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 herein, 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, a focusing lens 24, and a shaping lens 23. The light-emitting unit 21 is connected to the mounting base 10, and the light-emitting side of the light-emitting unit 21 faces away from the mounting base 10 and toward the light-receiving surface. The focusing lens 24 is arranged between the shaping lens 23 and the light-emitting side of the light-emitting unit 21 and is located on the light-emitting light path formed by the light-emitting unit 21. The light emitted by the light-emitting unit 21 transmits through the corresponding focusing lens 24 and the corresponding shaping lens 23 and then exits to the light-receiving surface to form a corresponding rectangular light spot. The multiple rectangular light spots formed by the multiple light-emitting modules 20 are arranged in sequence. Specifically, the multiple light-emitting modules 20 project light toward the light-receiving surface to form multiple corresponding light spots, thereby improving the light output brightness and light output range of the lamp 100 and enriching the decorative light effect. In this embodiment, each light-emitting module 20 includes a shaping lens 23. After the light formed by the multiple light-emitting modules 20 passes through the corresponding shaping lens 23, multiple rectangular light spots can be formed on the light receiving surface. Multiple rectangular light spots are arranged in sequence to form an arranged light effect, thereby improving the visual effect. In addition, each light-emitting module 20 includes a focusing lens 24. After the outgoing light of the light-emitting unit 21 passes through the focusing lens 24, the light can be converged on the shaping lens 23, thereby improving the utilization rate of the light and the brightness of the light output. In addition, the shaping lens 23 can shape the light spot into a rectangular light spot, and multiple rectangular light spots are arranged in sequence, thereby forming an orderly arrangement, thereby improving the effect of decorative light. Next, each component 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 can be understood that the more light-emitting modules 20 there are, the more rectangular light spots will be formed. Specifically, in this embodiment, the lamp 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 mounted on multiple mounting plates 11 and located on the side of the mounting plates 11 facing away from the arc center. Since the planes of adjacent mounting plates 11 are at a certain angle to each other, adjacent light-emitting modules 20 are staggered. This reduces the overlap between adjacent rectangular light spots formed by adjacent light-emitting modules 20 on the light-receiving surface, thereby improving the clarity of each rectangular light spot. In some embodiments, the aforementioned arc can be a circular arc.

[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 and the second end. 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 roughly 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-described embodiments includes multiple rectangular light spots c1, each of which is projected by 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 3In the present 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 the present embodiment, the light-emitting unit 21 is an incoherent light source, which can be a multi-color LED lamp bead such as a multi-color chip integrated lamp bead, a plurality of single-color lamp beads tightly patched, etc., so that each light-emitting module 20 can emit multiple colors of outgoing light. 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 in the same light-emitting unit 21 are turned on, they can form yellow light, green light, red light or other colors of excellent light. The color of the output light of each light-emitting unit 21 can be controlled according to actual usage requirements to form 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 of different colors are simultaneously illuminated, the resulting mixture of at least two different colors can further enhance the richness of the decorative light. For example, when red and blue light mix, purple light can be formed, 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 produce different, distinct light sources. 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] 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 that is generally flat and mounted on the mounting base 10, with each light-emitting module 20 disposed on the circuit board 30.

[0040] 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.

[0041] 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 light emission effects.

[0042] In this embodiment, each light-emitting unit 21 further includes a shaping lens 23, which can be a convex lens or a total internal reflection lens (TIR), and this embodiment does not limit this. The shaping lens 23 is arranged on the outgoing light path formed by the corresponding light-emitting unit 21, and the shaping lens 23 is used to shape the outgoing light of the light-emitting unit 21 to obtain a rectangular light spot. Specifically, each shaping lens 23 is detachably connected to the mounting seat 10, and a first accommodating space 231 is provided on the side of the shaping lens 23 facing the corresponding light-emitting unit 21, and the light-emitting unit 21 is arranged in the first accommodating space 231. The light from multiple light-emitting units 21 transmits the corresponding shaping lens 23 to form a plurality of rectangular light spot arrays on the light receiving surface, forming a lighting effect similar to a rainbow structure arrangement.

[0043] Specifically, the shaping lens 23 includes a lens portion 232 and a side wall portion 233. The side wall portion 233 is connected to the edge of the lens portion 232 and together defines the first receiving space 231. Figures 7 to 9The shaping lens 23 can be a cylindrical lens or an arched lens. The shaping lens 23 includes a light-emitting surface 2321 facing the light-receiving surface. The dimension of the light-emitting surface 2321 in the length direction Y is greater than the dimension of the light-emitting surface 2321 in the width direction X1. The lens portion 232 is used to transmit the outgoing light. The light-emitting surface 2321 of the lens portion 232 can be configured as a flat surface or a curved surface, thereby forming the shaping lens as a cylindrical lens or an arched lens. When the outgoing light passes through the lens portion 232, it is stretched to form a rectangular light spot. As an example, the light emitting surface 2321 of the lens portion 232 can be set as a rectangular plane, the light emitting surface 2321 has a length direction Y and a width direction X1 that are perpendicular to each other, and the light emitting surface 2321 includes a first side 2322 corresponding to the width direction X1 and a second side 2323 corresponding to the length direction Y, the first side 2322 is also extended along the extension direction X from the first end 101 to the second end 102 of the mounting seat 10, the second side 2323 is perpendicular to the extension direction X, the first side 2322 is used to stretch the shape of the light spot in the width direction into a straight line, and the second side 2323 is used to stretch the shape of the light spot in the length direction into a straight line, thereby forming a rectangular light spot. In this embodiment, the length of the light emitting surface 2321 is greater than the width of the light emitting surface 2321, that is, the size of the second side 2323 is greater than the size of the first side 2322. Specifically, the second side 2323 may be twice the size of the first side, thereby stretching the light spot into a rectangular light spot. The width and length of the rectangular light spot can be controlled by adjusting the lengths of the first side 2322 and the second side 2323 of the light emitting surface 2321, thereby forming a variety of light effects with different projection areas. Figure 3 In this embodiment, each shaping lens 23 has an optical axis O1. Because the multiple mounting plates 11 of the mounting base 10 are arranged along a specific arc between the first end 101 and the second end 102, which have a height difference, the multiple rectangular light spots formed on the light-receiving surface by the multiple light-emitting modules 20 are also arranged along the extension direction of the arc. The shaping lenses 23 have an optical axis O1, which is substantially perpendicular to the tangent direction of the arc. An optical axis angle a exists between the optical axes O1 of each pair of adjacent light-emitting modules 20. The value of the optical axis angle a can range from 5° to 25° (inclusive).

[0044] 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 light-emitting module 201 and the adjacent light-emitting module 20 can be 21°, the optical axis angle a between the tail light-emitting module 202 and the adjacent light-emitting module 20 can be 9°, and the optical axis angles a between the remaining multiple light-emitting modules 20 arranged in sequence can be 17°, 12°, and so on, so that the overlapping area between the multiple rectangular light spots c1 formed corresponding to the multiple light-emitting modules 20 is small, which can improve the clarity of each rectangular light spot c1. It should be noted that the value range of the optical axis angle a can also be other values. The different optical axis angles a between two adjacent light-emitting modules will result in different decorative light effects.

[0045] 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.

[0046] In this embodiment, the outgoing light of each light-emitting module 20 has a set beam angle d after passing through the shaping lens 23, and the value range of the beam angle d can be 10° to 25° (including the end points). As an example, the multiple beam angles d 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.

[0047] In some embodiments, in order to achieve a more uniform and clearer light emission effect, in the extension direction X from the first end 101 to the second end 102, the rated power of the light-emitting units 21 in the multiple light-emitting modules 20 can be increased in sequence. By increasing the brightness of the emitted light, the phenomenon that the rectangular light spot c1 becomes darker as the projection distance increases can be compensated, thereby forming a more uniform and clearer light emission effect. Specifically, in the extension direction X from the first end 101 to the second end 102, the rated power of the light-emitting units 21 in the multiple light-emitting modules 20 is increased in sequence, 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 power 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 is gradually increased, so that the brightness of the multiple rectangular light spots c1 can be adjusted to be approximately the same.

[0048] See also Figure 5In this embodiment, in order to make the color distinction between adjacent rectangular light spots obvious or improve the clarity of the light spots, the lamp 100 may further include a plurality of shading members 40, each of which 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 side wall portion 233 is located on at least one side of the light-emitting unit 21, which is connected to the mounting base 10 and protrudes relative to the lens portion 232. The shading member 40 may be a shading plate 41, which may protrude from the mounting base 10 and be disposed between the side wall portions 233 of each two adjacent light-emitting modules 20, so that the outgoing light formed by the light-emitting unit 21 cannot pass through the side wall portion 233. The shading plate 41 may be made of an opaque or translucent material, such as plastic, rubber, or specially treated paper. The light shielding plate 41 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 each other between adjacent light-emitting modules 20, reducing the overlap area between adjacent rectangular light spots, and ensuring the clarity of the adjacent rectangular light spots. In other embodiments, each light shielding plate 41 can be disposed around the side of the side wall portion 233 of each light-emitting module 20, specifically around the inner or outer wall of the side wall portion 233, which is not limited in this embodiment.

[0049] See also Figure 5 As another example, the light-shielding member 40 may be a light-shielding coating 42, which may be attached to the side wall portion 233 of each shaping lens 23, so that the outgoing light of each light-emitting module 20 is absorbed when passing through the light-shielding coating 42 and cannot be emitted to the adjacent light-emitting module 20, thereby reducing light interference with adjacent rectangular light spots. The light-shielding coating 42 may be a light-shielding pigment layer, a light-shielding ink layer, a light-shielding paint layer, or other light-shielding coating layers, which is not limited in this embodiment. In other embodiments, the light-shielding member 40 may also be a reflective layer, which may be a metal layer, so that the outgoing light can be reflected to the lens portion 232 via the reflective layer, and then emitted from the lens portion 232 to the light receiving surface, thereby improving the utilization rate of light and increasing the brightness of the rectangular light spot.

[0050] In order to better transmit the outgoing light to the shaping lens 23, in this embodiment, the lamp 100 also includes a plurality of focusing lenses 24, which are connected to the mounting plate 11 and are arranged one-to-one with the plurality of light-emitting modules 20. Each focusing lens 24 is used to converge the outgoing light of the corresponding light-emitting unit 21 to improve the utilization rate of the outgoing light. Specifically, each focusing lens 24 is arranged in the first accommodating space 231 of the corresponding shaping lens 23 and is located on the outgoing light path of the corresponding light-emitting unit 21. A second accommodating space 241 is provided on the side of each focusing lens 24 facing the corresponding light-emitting unit 21, and the light-emitting unit 21 is arranged in the second accommodating space 241. Therefore, the outgoing light of the light-emitting unit 21 is focused by the focusing lens 24 and then transmitted through the shaping lens 23, which can improve the brightness and emission efficiency of the outgoing light.

[0051] See also Figure 6 In this embodiment, each light-emitting module 20 further includes a light-mixing element 22. When the light-emitting unit 21 in each light-emitting module 20 forms excellent light of multiple colors, the light-mixing element 22 is used to mix the light to avoid the color boundary and the bright-dark boundary phenomenon of each light-emitting module 20. The light-mixing element 22 is arranged between the corresponding shaping 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 is fully mixed by the light-mixing element 22, so that the color distribution of the mixed light is more uniform, thereby avoiding the color separation of the outgoing light. The light-mixing element 22 can be specifically arranged in the second accommodating space 241, and each light-mixing element 22 also has an accommodating groove (not shown in the figure), which is arranged on the side facing the corresponding light-emitting unit 21. Specifically, the inner wall of the light-mixing element 22 defines a receiving groove, within which the light-emitting unit 21 is disposed. Specifically, the light-mixing element 22 can be a bowl-shaped structure that can be buckled onto the light-emitting unit 21, thereby effectively mixing the light emitted by the light-emitting unit 21. The light emitted by the light-emitting unit 21 is transmitted through the light-mixing element 22, which can improve the utilization rate of the emitted light to a certain extent and also provide protection for the light-emitting unit 21.

[0052] In summary, the present application provides a lamp 100 in one embodiment for illuminating a light-receiving surface. The lamp 100 includes a mounting base 10 and multiple light-emitting modules 20. The multiple light-emitting modules 20 are arranged on the mounting base 10 and project light toward the light-receiving surface, forming multiple corresponding light spots. This improves the brightness and range of the light emitted by the lamp 100 and enriches the decorative light effect. In this embodiment, each light-emitting module 100 includes a shaping lens 23. Light emitted by the multiple light-emitting modules 100, after passing through the corresponding shaping lens 23, forms multiple rectangular light spots on the light-receiving surface. Arranging the multiple rectangular light spots in sequence creates an array light effect, enhancing the visual effect. Furthermore, each light-emitting module 20 includes a focusing lens 24. Light emitted from the light-emitting unit 21, after passing through the focusing lens 24, converges onto the shaping lens 23, improving light utilization and brightness. Furthermore, the shaping lens 23 shapes the light spot into a rectangular light spot. The multiple rectangular light spots are arranged in sequence, forming an orderly arrangement, enhancing the decorative light effect.
