Technical Field

[0001] This application relates to the field of lighting fixtures, and particularly to a lighting device. Background Art

[0002] With the continuous progress and development in the field of modern lighting fixtures, space lighting has become an essential part, and consumers and designers have diverse requirements for the selection of the light distribution of lighting fixtures. Wall washer lights or ambient lights are a type of lighting fixture used for night scene lighting and engineering building decoration lighting. Common wall washer lights or ambient lights project light onto a wall to form a light spot within a specific range to achieve lighting or decorative effects. However, in actual use, the light-emitting angle of each wall washer light is fixed. When it is necessary to meet lighting beams with different angles or different light spot sizes, it is necessary to replace the lighting fixtures with different light-emitting angles and reinstall them. The disassembly and assembly of multiple lighting fixtures are relatively complex, and the usage cost is relatively high. Summary of the Utility Model

[0003] In view of this, the embodiments of this application provide a lighting device to solve the above technical problems.

[0004] The embodiments of this application provide a lighting device, which includes a mounting base and a plurality of lighting modules. The plurality of lighting modules are arranged on the mounting base. The lighting device has a light-emitting side, and the light-emitting side is located on the side of the plurality of lighting modules away from the mounting base. Each lighting module includes a light-emitting unit and a lens system. The light-emitting unit is connected to the mounting base, and the light-emitting surface of the light-emitting unit faces the light-emitting side to emit outgoing light rays towards the light-emitting side. The lens system is arranged on the optical path of the outgoing light rays. The outgoing light rays continue to propagate after passing through the lens system, and under the action of the lens system, an emission angle is formed on the light-emitting side. The emission angles of at least two of the plurality of lighting modules are different.

[0005] Wherein, in some embodiments, the plurality of lighting modules are arranged in parallel in sequence along a specified direction on the mounting base.

[0007] Wherein, in some embodiments, the outgoing light rays of the plurality of lighting modules are superimposed or mixed on the light-emitting side to form an outgoing light beam, and the light expansion angle range of the outgoing light beam is: greater than 0° and less than or equal to 70°.

[0008] Among them, in some embodiments, each lens system includes at least one first lens. At least one first lens is disposed on the optical path of the outgoing light of the corresponding lens system, and the diopters of the first lenses of multiple lens systems are different.

[0009] Among them, in some embodiments, the first lens is any one of the following structures: biconvex lens, plano-convex lens, and meniscus lens.

[0010] Among them, in some embodiments, the lens system further includes a second lens and a light guide. The light guide, the second lens, and the first lens are arranged in sequence on the optical path of the outgoing light of the corresponding lens system, and the second lens is located between the first lens and the light guide.

Each light shielding member is disposed between two adjacent lighting modules to space the two adjacent lighting modules apart, and each light shielding member extends from the mounting base towards the light-emitting side.

[0014] Among them, in some embodiments, the light shielding member includes a light shielding sleeve. Each light shielding sleeve is provided corresponding to each lighting module and is sleeved outside the corresponding lighting module.

[0015] Among them, in some embodiments, the lamp further includes a control unit, and the control unit is electrically connected to the light-emitting units of multiple lighting modules respectively and is used to control the operation of each light-emitting unit.

In addition, each lighting module includes a light-emitting unit and a lens system, and the light emitted by the light-emitting unit penetrates the lens system and then is emitted to the outside world, which can, on the one hand, focus light to improve the utilization rate of light and shape the light distribution, thereby forming a specific light spot; on the other hand, the light shaped by the lens system emits light more evenly, which can reduce the phenomenon of dark areas and uneven brightness distribution. Furthermore, the light emitted through the lens system will form an emission angle on the light-emitting side, and the emission angles of at least two lighting modules are different.

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

[0031] Please refer to Figure 1, an embodiment of the present application provides a lighting fixture 100. In this embodiment, the lighting fixture 100 is used to emit light towards a light receiving surface, and the lighting fixture 100 can be a wall washer or an ambient light. The light receiving surface can be a ceiling, a wall, a floor, etc. As an example, the lighting fixture 100 is a wall washer, which is used to provide lighting for a wall. As another example, the lighting fixture 100 can be an ambient light, specifically installed on the back of a display screen to play a decorative role.

[0032] Please refer to 1 and Figure 2 , in an embodiment provided by the present application, the lighting fixture 100 includes a mounting base 10 and a plurality of lighting modules 20, and the plurality of lighting modules 20 are disposed on the mounting base 10. The lighting fixture 100 has a light-emitting side 202, and the light-emitting side 202 is located on a side of the plurality of lighting modules 20 away from the mounting base 10. Each lighting module 20 includes a light-emitting unit 21 and a lens system 22. The light-emitting unit 21 is connected to the mounting base 10, and an outgoing light surface 201 of the light-emitting unit 21 faces the light-emitting side 202 for emitting outgoing light towards the light-emitting side 202. The lens system 22 is disposed on the optical path of the outgoing light. After the outgoing light penetrates the lens system 22, it continues to propagate, and an emission angle is formed on the light-emitting side 202 under the action of the lens system 22. The emission angles of at least two of the plurality of lighting modules 20 are different.

[0033] Specifically, the plurality of lighting modules 20 are disposed on the mounting base 10 and jointly emit outgoing light towards the light-emitting side 202, so as to be able to form a relatively large lighting range. The outgoing light formed by the light-emitting unit 21 of each lighting module 20 penetrates the lens system 22 and then exits to the outside. On the one hand, it can play a role in concentrating light to improve light utilization rate and shaping the light distribution, so as to form a specific light spot. On the other hand, the light emitted after being shaped by the lens system 22 is more uniform in light output, and can reduce the phenomenon of dark areas and uneven brightness distribution. Further, the light emitted through the lens system 22 will form an emission angle on the light-emitting side 202, and the emission angles of at least two lighting modules 20 are different, so that a lighting fixture 100 can form at least two different light spots. On the one hand, it is not necessary to set multiple lighting fixtures 100 to achieve multiple light spot illuminations, saving the installation and maintenance time during the use of the lighting fixture 100, thereby reducing the use cost of the lighting fixture 100. On the other hand, the linkage of multiple outgoing lights with different emission angles can form different lighting effects or decorative effects, meet the lighting requirements of various use scenarios, and improve the user experience.

[0034] The light-emitting side 202 can be understood as the side where the emitted light rays of the plurality of light-emitting units 21 are emitted to the side of the lens system 22 away from the mounting base 10. Among them, the light-emitting surface 201 of the light-emitting unit 21 is arranged facing the light-emitting side 202, and the light-emitting side 202 can be arranged facing the light-receiving surface. The light-receiving surface can be a vertical plane (such as a wall surface). As an example, the light-emitting side 202 can be parallel and opposite to the light-receiving surface, and the emitted light rays of the light-emitting unit 21 can be projected above or below the light-receiving surface corresponding to the installation height of the lamp 100 in the vertical direction, so as to achieve the effect of seeing the light but not the lamp, avoid the lamp 100 from blocking the user's line of sight at a certain angle, and thus improve the user's viewing experience. The light-receiving surface can also be a horizontal plane (such as a ceiling or a ground, a step surface, etc.).

[0035] Next, each component of the lamp 100 and the specific structure of each component will be introduced one by one.

[0036] Please refer to Figure 2 , in this embodiment, the mounting base 10 serves as the mounting carrier of the lamp 100, which is used to mount a plurality of lighting modules 20 and fix the lamp 100 on the mounting platform. The mounting platform can be a wall surface, a ceiling or other brackets, etc. The mounting base 10 is generally in the shape of a long plate and has a length extension direction. The inside of the mounting base 10 can include a circuit board 11, and the circuit board 11 is used to provide electrical energy for the plurality of lighting modules 20 to realize the internal and external conduction between the lighting module 20 and the external circuit. Specifically, the circuit board 11 is generally in the shape of a long plate, and a plurality of lighting modules 20 are arranged on the circuit board 11. The circuit board 11 can include a power module 111, and the number of power modules 111 can be one or more. As an example, the number of power modules 111 is one, and one power module 111 is connected to a plurality of lighting modules 20 at the same time to supply power to a plurality of lighting modules 20 at the same time. As another example, the number of power modules 111 is multiple, and the multiple power modules 111 and the multiple lighting modules 20 are respectively connected correspondingly to independently control the power-on of the multiple lighting modules 20. The circuit board 11 can include a control unit 112, and the control unit 112 can be a control chip. The number of control units 112 can be one, and one control unit 112 is connected to a plurality of lighting modules 20 at the same time to control the respective operations of the plurality of lighting modules 20 at the same time. As another example, the number of control units 112 can be multiple, and the multiple control units 112 and the light-emitting units 21 of the multiple lighting modules 20 are respectively electrically connected, and each control unit 112 is used to control the operation of each lighting module 20, which can realize single-point control and improve the working stability and reliability of the lamp 100. Specifically, the multiple control units 112 can independently control the light-emitting brightness, flicker frequency, light color, lighting time, etc. of the corresponding lighting modules 20, so that the working parameters of each lighting module do not interfere with each other, and thus a variety of lighting effects or decorative lighting effects can be formed.

[0037] In this embodiment, a plurality of lighting modules 20 are used to respectively form a plurality of outgoing light beams. The plurality of lighting modules 20 are detachably connected to the mounting base 10, which is convenient for installation and maintenance. The plurality of lighting modules 20 are arranged side by side along a specified direction on the mounting base 10. Specifically, they can be linearly arranged along the length direction of the mounting base 10. Thus, the outgoing light paths formed by the plurality of lighting modules 20 are arranged side by side and face the light receiving surface, and a relatively large lighting area or decorative area can be formed on the light receiving surface. At the same time, different lighting effects and decorative effects can be formed by setting the spacing between adjacent lighting modules 20. Each lighting module 20 includes a light emitting unit 21 and a lens system 22. The lens system 22 is located on the light path of the outgoing light formed by the light emitting unit 21. Specifically, the light emitting unit 21 is connected to the mounting base 10, and specifically, it can be connected to the circuit board 11, so that the circuit board 11 can supply power to the light emitting unit 21.

[0038] In this embodiment, the light emitting unit 21 has a light emitting surface 201, and the light emitting surface 201 faces the light emitting side 202. The light emitting unit 21 is an incoherent light source. The light emitting unit 21 can be a high-pressure gas light emitting unit 21 such as a halogen light bulb, a UHP (ultra-high pressure mercury lamp), a UHE (ultra-high pressure mercury lamp), or an LED light source, etc. In this embodiment, the light emitting unit 21 is an LED light source. Specifically, it can be a monochromatic LED lamp bead or a multi-color LED lamp bead. On the one hand, it can improve the efficiency of converting electrical energy into light energy, thereby reducing energy waste. At the same time, the heat generated during the lighting of the LED light source is less, playing a role in energy conservation and environmental protection. On the other hand, the service life of the LED light source is long, reducing the frequency of light source replacement and thus reducing the use cost. At the same time, the LED can avoid damaging the human eyes and improve the use safety.

[0039] As an example, the colors of the light emitting units 21 of the plurality of lighting modules 20 can be different from each other, so that a plurality of colors of outgoing light beams can be formed. For example, red light, blue light, white light, etc. This embodiment does not make specific limitations on this. As another example, the rated powers of the light emitting units 21 in the plurality of lighting modules 20 can be different, so that outgoing light beams with different brightnesses can be formed, and a lighting effect or decorative effect with light and dark changes can be formed on the light receiving surface.

[0040] The lens system 22 is located on the optical path of the outgoing light rays formed by the corresponding light-emitting unit 21. The lens system 22 is used to converge or diverge the light rays of the light-emitting unit 21 and emit the light rays to the light-receiving surface at a certain exit angle. Specifically, when the light-emitting unit 21 is an incoherent light source, the lens system 22 can converge the diverging light rays to the light-emitting side and emit the light rays to the light-receiving surface at a certain angle. When the light-emitting unit 21 is a coherent light source, the lens system 22 receives the collimated light rays from the light-emitting unit 21 and disperses the light rays to the light-emitting side 202 to form a larger illumination area or decorative area. In this embodiment, multiple light rays penetrate through multiple lens systems 22, and the exit angles formed by at least two of the multiple lens systems 22 are different. By setting the lens system 22, on the one hand, the light-emitting uniformity of the outgoing light rays can be improved, and the phenomena of dark areas and uneven brightness distribution can be reduced. On the other hand, the exit angles of at least two of the multiple lens systems 22 are different, so that a single lamp 100 can form at least two light spots with different illumination ranges. Without the need to set multiple lamps 100, multiple light spot illuminations can be achieved, which can save the installation and maintenance time during the use of the lamp 100 and reduce the use cost of the lamp 100.

[0041] Please refer to Figure 3 , specifically, each lens system 22 includes a lens barrel 221 and a lens assembly 222. The lens barrel 221 extends from the mounting base 10 towards the light-emitting side 202. The lens barrel 221 has an accommodation space 2211, and the lens assembly 222 is disposed within the lens barrel 221. The outgoing light rays formed by the light-emitting unit 21 are transmitted through the lens assembly 222 to the light-receiving surface. Since the lens assemblies 222 in the multiple lighting modules 20 can have different optical characteristics, the outgoing light rays can form different exit angles on the light-emitting side 202, thereby presenting different illumination effects or decorative effects on the light-receiving surface.

[0042] Please refer to Figure 3 , in this embodiment, the lens assembly 222 may include at least one first lens 2221. At least one first lens 2221 is disposed within the lens barrel 221 of the corresponding lens system 22 and is located on the optical path of the outgoing light rays. The first lens 2221 is used to change the exit angle of the outgoing light rays. Specifically, the diopters of the first lenses 2221 of the multiple lens systems 22 are different. As an example, the materials of the first lenses 2221 in the multiple lens systems 22 are different, that is, due to the different materials of the first lenses 2221, the refractive indices of the light rays are different. Thus, when the outgoing light rays are transmitted through the first lenses 2221 made of different materials, different exit angles can be formed on the light-emitting side 202. The material of the first lens 2221 can be optical plastic, optical resin, optical glass, etc., and this embodiment does not make specific limitations on this.

[0043] Please refer to Figure 4, as another example, the structures of the first lenses 2221 in at least two lighting modules 20 are different, so that the exit angles formed by the exit light rays transmitted through different first lenses 2221 are different. For example, the first lens 2221 can be any one of the following structures: a biconvex lens, a plano-convex lens, and a concavo-convex lens. Specifically, please refer to Figure 4 and Figure 5 , when the first lens 2221 in one of the lighting modules 20 is a biconvex lens, the biconvex lens has an incident light surface 2224 and an exit light surface 2225, and both the incident light surface 2224 and the exit light surface 2225 are outwardly convex surfaces. The exit light ray penetrates the biconvex lens and has a first exit angle a on the exit light side 202, and the value range of the first exit angle a is greater than 0° and less than or equal to 30°, and specifically can be 5°, 15°, 20°, 30°, etc. Please refer to Figure 4 and 6 , when the first lens 2221 in one of the lighting modules 20 is a plano-convex lens, the plano-convex lens has an incident light surface 2224 and an exit light surface 2225, the exit light surface 2225 is an outwardly convex surface, and the incident light surface 2224 can be a flat surface. The exit light ray penetrates the plano-convex lens and has a second exit angle b on the exit light ray, and the value range of the second exit angle b is greater than 30° and less than or equal to 50°, and specifically can be 35°, 40°, 45°, 50°, etc. Please refer to Figure 4 and Figure 7 , when the first lens 2221 in one of the lighting modules 20 is a concavo-convex lens, the incident light surface 2224 of the concavo-convex lens is an inwardly concave surface, and the exit light surface 2225 is an outwardly convex surface. The exit light ray penetrates the concavo-convex lens and has a third exit angle c on the exit light side 202, and the value range of the third exit angle c is greater than 50° and less than or equal to 70°, and specifically can be 55°, 60°, 65°, 70°, etc., and this embodiment does not make specific limitations on this.

[0044] It can be understood that when the emitted light rays of multiple lighting modules 20 are superimposed or mixed on the light-emitting side 202 to form an emitted light beam, the light expansion angle of the emitted light beam is relatively large, and a larger lighting area or decorative area can be formed. Specifically, when the lighting module 20 with the first emission angle a and the lighting module 20 with the second emission angle b emit light rays towards the light-receiving surface simultaneously, the value range of the light expansion angle of the emitted light beam after mixing or superimposing is greater than 0° and less than or equal to 50°. The emitted light beam after mixing or superimposing includes both the illumination range of the first emission angle a and the illumination range of the second emission angle b, and can form a larger lighting area or decorative area. When the lighting module 20 with the second emission angle b and the lighting module 20 with the third emission angle c emit light rays towards the light-receiving surface simultaneously, the value range of the light expansion angle of the emitted light beam after superimposing or mixing is greater than 30° and less than or equal to 70°, that is, it includes both the illumination range of the second emission angle b and the illumination range of the third emission angle c, further forming a larger lighting area or decorative area. When multiple lighting modules 20 respectively having the first emission angle a, the second emission angle b, and the third emission angle c work simultaneously, the value range of the light expansion angle of the emitted light beam formed after superimposing or mixing is greater than 0° and less than or equal to 70°, that is, it includes both the illumination range of the first emission angle a, the illumination range of the second emission angle b, and the illumination range of the third emission angle c. Through the cooperation between multiple lighting modules 20 in the lamp 100, emitted light rays with multiple emission angles can be formed, and multiple corresponding angular range lighting areas or decorative areas can be formed, which can meet various usage scenarios and improve the user experience. In addition, the lighting module 20 with the first emission angle a and the lighting module 20 with the third emission angle c can also work simultaneously, and the value range of the light expansion angle of the emitted light beam formed after superimposing or mixing is greater than 0 degree and less than or equal to 30°, greater than 50° and less than or equal to 70°.

[0045] It should be noted that the emitted light formed by multiple lighting modules 20 may also include a fourth emission angle, a fifth emission angle, or other emission angles, and this embodiment does not limit this. Specifically, it can be achieved by adjusting the distance between the first lens 2221 and the corresponding light-emitting unit 21 in some of the multiple lighting modules 20, so that the emitted light forms different emission angles. It can also be achieved by adjusting the number of the first lenses 2221 in different lighting modules 20, so that the emitted light penetrates different numbers of the first lenses 2221 to form different emission angles. For example, one of the lighting modules 20 may include one first lens 2221, another lighting module 20 may include two first lenses 2221, and still another lighting module 20 may include three first lenses 2221. For a lighting module 20 including two or more first lenses 2221, the spacing distance between adjacent first lenses 2221, as well as the type and material of the lenses, are not limited in this embodiment. It can be understood that the emitted light penetrating the first lenses 2221 with different spacing distances or penetrating the first lenses 2221 with different refractive powers and materials will form different emission angles, so that the light formed by the lamp 100 can cover different lighting areas or decorative areas.

[0046] Please refer to again Figure 3 , in order to better conduct the emitted light to the first lens 2221, in this embodiment, each lens system 22 further includes a second lens 2222. The second lens 2222 and the first lens 2221 are arranged in sequence in the barrel 221 of the corresponding lens system 22 and are located on the optical path of the emitted light. In this embodiment, the second lens 2222 of each lighting module 20 is used for condensing light, and the second lens 2222 is located on the side of the first lens 2221 away from the light-emitting side. 每个 The number of the second lenses 2222 in the lighting module 20 is one and is a convex lens. The emitted light is conducted to the second lens 2222 through the light guide member 2223 for condensing and then conducted to the outside through the first lens 2221. The material of the second lens 2222 can be an optical lens, plastic, optical resin, etc., and this embodiment does not make specific limitations on this. It can be understood that in some embodiments, the number of the second lenses 2222 in each lighting module 20 is not limited. The purpose of setting the second lens 2222 is to converge light, and one or more second lenses 2222 or no second lens 2222 can be set according to actual use needs. The number, material, and combination method of multiple second lenses 2222 in each lighting module 20 are not specifically limited in this embodiment.

[0047] Please refer to Figure 8 and Figure 9, Further, in some embodiments, each lens system 22 may further include a light guide member 2223. The light guide member 2223, the second lens 2222, and the first lens 2221 are arranged in sequence within the barrel 221 of the corresponding lens system 22 and are located on the optical path of the corresponding outgoing light. Specifically, the light guide member 2223 is made of an optical material, such as optical plastic, polycarbonate, epoxy resin, or glass, etc., and is used to converge and mix light and guide the propagation direction of the outgoing light. The light guide member 2223 can be a columnar light homogenizing rod, specifically, it can be a cylindrical light guide rod, a frustum light guide rod, a prism frustum light guide rod, a truncated cone light guide rod, etc. Different shapes of the light guide member 2223 and different materials of the light guide column result in different light output effects. In this embodiment, no specific limitation is imposed on the shape setting of the light guide member 2223. The light guide member 2223 has a length direction, and the length direction of the light guide member 2223 is consistent with the extending direction of the optical axis of the second lens 2222, that is, it extends from the self-luminous unit 21 towards the light output side 202. Thus, the light guide column extends from the self-luminous unit 21 towards the light output side 202, which can more effectively transmit the light emitted by the light-emitting unit 21 to the first lens 2221, reduce the light loss during transmission, and thereby improve the overall light efficiency. At the same time, it can effectively control the propagation direction of the light, reduce the light directly irradiating the observer's eyes, reduce glare, and provide a more comfortable lighting environment. Further, the light guide member 2223 also functions to narrow the light. The outgoing angle of the outgoing light when it is conducted out of the light guide member 2223 becomes smaller, so that the outgoing light can enter the first lens 2221 at a smaller angle, ensuring a higher light energy utilization rate.

[0048] In some embodiments, the light guide member 2223 may further include a scattering medium (not shown in the figure), and the scattering medium is used to further improve the light output uniformity. The scattering medium can be a micro-structure (not shown in the figure), and the micro-structure can be provided inside the light guide member 2223 or on the surface of the light guide member 2223. In this embodiment, no specific limitation is imposed on the shape and size of the micro-structure. Only as an example, the micro-structure can be a micro-prism, and the micro-prism is provided on the surface of the light guide member 2223. The scattering medium can also be scattering particles (not shown in the figure), and the scattering particles are provided inside the light guide member 2223. The scattering particles can be fine glass particles, silicon oxide particles, titanium oxide particles, etc. In this embodiment, no specific limitation is imposed on the particle material and the particle radius. In some other embodiments, the light guide member 2223 may further include a reflective coating (not shown in the figure) or a light diffusion film layer (not shown in the figure), and the reflective coating or the light diffusion layer is provided on the surface of the light guide member 2223.

[0049] Please refer to Figure 10, in this embodiment, when the colors of the emitted light rays formed by multiple lighting modules 20 are different, in order to make each lighting module 20 have obvious color or brightness differentiation on the light receiving surface, the lighting fixture 100 may further include a plurality of light-shielding members 30. Each light-shielding member 30 is disposed between two adjacent lighting modules 20 to space apart the two adjacent lighting modules 20. In this embodiment, the light-shielding member 30 may extend from the mounting base 10 toward the light-emitting side 202, thereby preventing the light rays between adjacent light-emitting units 21 from interfering with each other and ensuring the light clarity of the lighting area or the decorative area. As an example, the light-shielding member 30 is a light-shielding sleeve 31. Each light-shielding sleeve 31 is provided in one-to-one correspondence with each lighting module 20 and is detachably sleeved outside the corresponding lighting module 20. By providing the light-shielding sleeve 31, it helps to reduce the strong light directly emitted from the light source from entering the observer's eyes, reduce glare, improve visual comfort, and at the same time, it also helps to control the direction and range of the light rays, making the light rays more concentrated and evenly irradiate on the lighting area or the decorative area.

[0050] As another example, the light-shielding member 30 may also be a light-shielding plate 32. Each light-shielding plate 32 is disposed between adjacent lighting modules 20 to space apart the two adjacent lighting modules 20. The light-shielding plate 32 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 can block the direct line of sight, ensuring that the light rays of each light-emitting unit 21 are restricted within its predetermined lighting area or decorative area, thereby preventing the light rays between different light-emitting units 21 from mixing and interfering. It can be understood that in order to reduce the occurrence of dark areas between adjacent lighting modules 20, the thickness of the light guide member 2223 may be relatively small, so that the distance between adjacent lighting modules 20 is relatively small.

[0051] In summary, the present application provides a lamp 100 in an embodiment, the lamp 100 includes a mounting base 10 and a plurality of lighting modules 20, the plurality of lighting modules 20 are arranged on the mounting base 10 and jointly emit outgoing light to the light-emitting side 202, so as to form a larger lighting range. In addition, each lighting module 20 includes a light-emitting unit 21 and a lens system 22, and the outgoing light formed by the light-emitting unit 21 penetrates the lens system 22 and then emits to the outside world, which can, on the one hand, play the role of focusing light to improve the utilization rate of light and shape the distribution of light, thereby forming a specific light spot; on the other hand, the light shaped by the lens system 22 emits more uniformly, which can reduce the phenomenon of dark areas and uneven brightness distribution. Furthermore, the light emitted by the lens system 22 will form an outgoing angle on the light-emitting side 202, and the outgoing angles of at least two lighting modules 20 are different. When at least two lighting modules 20 with different emission angles work simultaneously, the emitted light at different emission angles can enable the lamp 100 to form at least two different light emission angles, so that one lamp 100 can form at least two light spots with different lighting ranges. On the one hand, it is not necessary to set up multiple lamps 100 to achieve the formation of multiple light spot lighting, saving installation and maintenance time during the use of the lamp 100, thereby reducing the use cost of the lamp 100. On the other hand, the linkage of multiple emission lights with different emission angles can form different lighting effects or decorative effects, meet the lighting requirements of various usage scenarios, and improve the user experience.
