Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to a light-emitting module and a lighting fixture. Background Technology

[0002] To meet the needs of various lighting scenarios, existing luminaires often integrate LEDs of different colors, temperatures, or color temperatures in concentric rings on the same panel, allowing a single luminaire to emit light of multiple colors or color temperatures. However, the alternating ring arrangement of multiple LEDs results in inconsistent light spot sizes, leading to an uneven light distribution. Utility Model Content

[0003] This application provides a light-emitting module and a lamp to solve the above-mentioned problems.

[0004] According to a first aspect of this application, an embodiment of this application provides a light-emitting module, including a base, a light-emitting component, and a dimming component. The light-emitting component is disposed on the base and includes multiple light-emitting units, which are divided into multiple first light-emitting groups and multiple second light-emitting groups. The multiple light-emitting units in each second light-emitting group are spaced apart from each other, and the multiple light-emitting units in the first light-emitting groups are arranged sequentially around the outer periphery of the second light-emitting groups. The light-emitting parameters of the first light-emitting groups and the second light-emitting groups are different, and the light-emitting parameters include at least one of brightness, color, and color temperature. The dimming component is located in the light path formed by the light-emitting component and has a lens portion. The lens portion corresponds to the light-emitting component so that the ratio of the light spot area formed by the first light-emitting group on a designated light-receiving plane to the light spot area formed by the second light-emitting group on the designated light-receiving plane is greater than 0.8 and less than 1.2.

[0005] In some embodiments, there are multiple lens portions, and each lens portion corresponds one-to-one with a multiple light-emitting unit in the first light-emitting group, with each lens portion encapsulated on the surface of a corresponding light-emitting unit.

[0006] In some embodiments, there are multiple lens portions, and the multiple lens portions correspond one-to-one with the multiple light-emitting units in the second light-emitting group, with each lens portion encapsulated on the surface of a corresponding light-emitting unit.

[0007] In some embodiments, the dimming element includes a body and a lens. The body and the light-emitting side of the light-emitting component are disposed opposite to each other. The lens is disposed on the surface of the body and is used to deflect the light from the light-emitting component at an angle.

[0008] In some embodiments, the number of lens portions is one, and the lens portion is located in the optical path of the first light-emitting group or in the optical path of the second light-emitting group.

[0009] In some embodiments, there are multiple lens sections, which are spaced apart from each other. The multiple lens sections correspond one-to-one with the multiple light-emitting units in the first light-emitting group, or the multiple lens sections correspond one-to-one with the multiple light-emitting units in the second light-emitting group.

[0010] In some embodiments, the lens section includes a diffuser lens located in the optical path formed by the second light-emitting group.

[0011] In some embodiments, the lens section includes a converging lens located on the optical path formed by the first light-emitting group.

[0012] In some embodiments, the lens section includes a diffuser lens and a converging lens, which are spaced apart. The diffuser lens is located on the optical path formed by the second light-emitting group, and the converging lens is located on the optical path formed by the first light-emitting group.

[0013] In some embodiments, the light-emitting module further includes a light-mixing component, which is located on the light path formed by the light-emitting component. The light-mixing component is connected to the base and has a mounting groove. The light-emitting component and the dimming component are disposed in the mounting groove. The light generated by the light-emitting component is emitted to the outside through the dimming component and the light-mixing component in sequence.

[0014] In some embodiments, the first light-emitting group includes a plurality of first LED beads and a plurality of second LED beads, which are arranged alternately on the outer periphery of the second light-emitting group. The first LED beads and the second LED beads are monochrome LED beads, and the color temperatures of the first LED beads and the second LED beads are different.

[0015] In some embodiments, the second light-emitting group includes multiple colored LEDs, and the light-emitting module also includes a third light-emitting group. The second light-emitting group is arranged around the outer periphery of the third light-emitting group, and the light-emitting parameters of the third light-emitting group are the same as those of the first light-emitting group.

[0016] According to a second aspect of this application, an embodiment of this application provides a lamp, including a light-emitting lens and a light-emitting module as described above, wherein the light-emitting lens is located in the optical path formed by the light-emitting module.

[0017] In some embodiments, the light-emitting lens protrudes toward the side opposite to the light-emitting module, the light-emitting lens has a central axis, the light-emitting lens is symmetrical about the central axis, and the light-emitting module and the light-emitting lens are coaxially arranged so that the emission angle formed by the light-emitting module emitting light from any position of the light-emitting lens is the same.

[0018] Compared to existing technologies, this embodiment provides a light-emitting module, including a base, a light-emitting component, and a dimming device. The light-emitting component comprises multiple light-emitting units divided into multiple first light-emitting groups and multiple second light-emitting groups. The light-emitting parameters of the first and second light-emitting groups differ, thereby enabling the creation of various light-emitting effects within the same light-emitting module to meet diverse lighting needs. Furthermore, the dimming device is positioned in the optical path of the light-emitting component. The lens portion of the dimming device corresponds to the light-emitting component to adjust the area of ​​the light spots formed by the first and second light-emitting groups. The ratio of the area of ​​the light spot formed by the first light-emitting group on a designated light-receiving plane to the area of ​​the light spot formed by the second light-emitting group is greater than 0.8 and less than 1.2, meaning the areas of the light spots formed by the first and second light-emitting groups are approximately the same. This effectively avoids uneven brightness and color temperature distribution caused by excessive differences in light spot area, improving the uniformity of light emission from the light-emitting module and thus enhancing the overall light-emitting effect, providing users with a more comfortable and natural visual experience.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Please see Figure 1 and Figure 2 This application provides a light-emitting module 100. The light-emitting module 100 includes a base 10, a light-emitting component 20, and a dimming component 30. The light-emitting module 100 is used to project light spots onto a designated light-receiving plane, and also to adjust the area of ​​the light spots so that the areas of the formed light spots are approximately the same to improve light emission uniformity. The designated light-receiving plane is a plane used to receive and display the light spot or light range, which may include reflective parts such as the ground, walls, and ceilings. The designated light-receiving plane can also be a virtual plane or a plane used for testing. For example, a plane perpendicular to the optical axis of the light-emitting module 100 and having a certain distance from the light-emitting module 100 can be set. This embodiment does not limit the specific value of the distance. The light emitted by the light-emitting module 100 can form light spots of approximately the same area on the designated light-receiving plane. The light-emitting module 100 can be applied to lighting fixtures. Depending on the shape or pattern of the projected light spot, the lighting fixture can be a decorative lamp or a general lighting fixture. This application embodiment does not impose specific limitations in this regard. As an example, the light-emitting module 100 can be applied to a spotlight to provide illumination or decorative light to a designated illuminated surface.

[0037] Please see Figure 3 and Figure 4 This application embodiment also provides a lamp 200, which is used to provide illumination light or decorative light. The lamp 200 may include a housing 201, which serves as a mounting carrier for mounting components and protecting them. The mounting components may include a light-emitting module 100, a heat sink (not shown in the figure), etc., and this embodiment does not impose specific limitations on these components. In this embodiment, the mounting components may include a light-emitting lens 202, which is located in the optical path formed by the light-emitting module 100 to configure the light. This embodiment does not limit the specific form of the light-emitting lens 202; for example, it may be a total internal reflection lens, a plane lens, a curved lens, etc. As an example, in this application, the light-emitting lens 202 is specifically a converging lens 312, such as a convex lens, which protrudes toward the side away from the light-emitting module 100 to form a light-emitting surface. Multiple light rays emitted from the light-emitting module 100 are converged by the light-emitting lens 202 and emitted at a certain emission angle beyond the light-emitting surface, forming multiple light spots on a designated light-receiving plane, thereby improving the light output brightness of the lamp 200.

[0038] In order to make the multiple light spots or light rays formed on the specified light-receiving plane more uniform, in some embodiments, the light-emitting lens 202 can be symmetrical about the central axis O1, and the light-emitting module 100 and the light-emitting lens 202 are coaxially arranged.

[0039] Specifically, the light-emitting component 20 in the light-emitting module 100 may include multiple light-emitting units 21. These multiple light-emitting units 21 can be arranged symmetrically along a central axis, so that the light emitted by the light-emitting module 100 is approximately symmetrical about the center of the light-emitting component 20. Consequently, the light spot distribution and area formed on the designated light-receiving plane by the light emitted by the light-emitting module 100 are relatively uniform. This embodiment does not limit the specific form in which the multiple light-emitting units 21 are arranged symmetrically along a central axis. For example, the multiple light-emitting units 21 can be arranged in concentric rings or concentric rectangles at intervals, or linearly symmetrically, or radially arranged sequentially. The arrangement can be customized according to actual usage requirements. In this embodiment, the light-emitting lens 202 has a central axis O1 and is symmetrical about the central axis O1. Since the light-emitting module 100 and the light-emitting lens 202 are coaxially arranged, and the light spot areas of the multiple beams of light generated by the light-emitting component after being dimmed by the dimming device are approximately the same, the emission angles formed by the light emitted by the light-emitting module 100 after being emitted from any position of the light-emitting lens 202 are approximately the same. This avoids problems such as uneven light spot brightness and blurred edges caused by inconsistent light emission angles, and further improves the uniformity of light emission.

[0040] It should be noted that this embodiment does not limit the specific shape of the light-emitting lens 202 symmetrical about the central axis O1. As an example, the light-emitting surface 2021 of the light-emitting lens 202 can be a symmetrical arc surface with the same curvature, and the central axis O1 passes through the vertex of the arc. As another example, the light-emitting surface can be formed by connecting arc surface segments with different curvatures in sequence, with multiple arc surface segments symmetrical about the central axis O1. By setting arc surface segments with different curvatures, the difference in light spots caused by the different distances between some light-emitting units 21 and the central axis O1 can be adjusted, further improving the uniformity of light emission. It is understood that in some embodiments, the light-emitting surface can also be composed of multiple straight line segments symmetrically arranged about the central axis O1, which can be set according to actual usage requirements.

[0041] See again Figure 2 and Figure 5In one embodiment provided in this application, the light-emitting module 100 includes a base 10, a light-emitting component 20, and a dimming component 30. The light-emitting component 20 is disposed on the base 10 and includes multiple light-emitting units 21. These units are divided into multiple first light-emitting groups 22 and multiple second light-emitting groups 23. The multiple light-emitting units 21 in each second light-emitting group 23 are spaced apart from each other. The multiple light-emitting units 21 in the first light-emitting groups 22 are arranged sequentially around the outer periphery of the second light-emitting groups 23. The light-emitting parameters of the first light-emitting groups 22 and the second light-emitting groups 23 are different, and the light-emitting parameters include at least one of brightness, color, and color temperature. The dimming component 30 is located in the optical path formed by the light-emitting component 20. The dimming component 30 has a lens portion 31, which corresponds to the light-emitting component 20 so that the ratio of the area of ​​the light spot formed by the first light-emitting group 22 on a specified light-receiving plane to the area of ​​the light spot formed by the second light-emitting group 23 on the specified light-receiving plane is greater than 0.8 and less than 1.2.

[0042] By dividing multiple light-emitting units 21 into multiple first light-emitting groups 22 and multiple second light-emitting groups 23, the light-emitting parameters of the first light-emitting groups 22 and the second light-emitting groups 23 are different, thereby enabling the formation of multiple different light-emitting effects in the same light-emitting module 100 to meet various lighting needs. For example, when the light-emitting parameters include brightness, the light spots formed by the first light-emitting groups and the second light-emitting groups have different brightness, thereby enabling the formation of specific lighting effects with different brightness on a specified light-receiving plane to improve the user's visual experience. Furthermore, the dimming element 30 is disposed in the optical path of the light-emitting component 20. The lens portion 31 of the dimming element 30 corresponds to the light-emitting component 20 to ensure that the ratio of the light spot area formed by the first light-emitting group 22 on the designated light-receiving plane to the light spot area formed by the second light-emitting group 23 is greater than 0.8 and less than 1.2. For example, the ratio of the light spot area formed by the first light-emitting group 22 and the second light-emitting group 23 can be 0.9, 1, 1.1 or other values, that is, the light spot area formed by the first light-emitting group 22 and the light spot area formed by the second light-emitting group 23 are approximately the same, which can effectively avoid the problem of uneven brightness and color temperature distribution caused by excessive difference in light spot area, improve the light emission uniformity of the light-emitting module 100, and thus improve the overall light emission effect, providing users with a more comfortable and natural visual experience.

[0043] The following sections will introduce each component of the optical module 100 and its specific structure.

[0044] Please see Figure 2 and Figure 5In this embodiment, the base 10 is generally flat and serves as a mounting carrier for mounting the light-emitting component 20. The base 10 can be integrally formed with the light-emitting component 20 or detachably connected to the light-emitting component 20; this embodiment does not impose specific limitations on this. The base 10 can be disposed inside the housing 201 of the lamp 200 to connect and fix the light-emitting module 100 and the lamp 200, or it can serve as a support member on a mounting platform, which can be a desktop, wall, ceiling, or other mounting bracket.

[0045] The base 10 also powers the light-emitting component 20. Specifically, the base 10 has a circuit board (not shown in the figure) inside. The circuit board may include a power module electrically connected to the light-emitting component 20 to power it. The circuit board may also include a control module, which may be a control chip. There may be one control chip, which is simultaneously connected to the light-emitting component 20 to control multiple light-emitting units 21 of the light-emitting component 20 to operate at the same time. As another example, there may be multiple control chips, which are electrically connected to multiple light-emitting units 21 to control the operation of the corresponding light-emitting units 21, thereby enabling single-point control and improving the working stability and reliability of the lamp 200.

[0046] In this embodiment, the light-emitting component 20 is used to generate emitted light. The light-emitting component 20 may include multiple light-emitting units 21, which are arranged sequentially and at intervals on the base 10. In this embodiment, the multiple light-emitting units 21 can be divided into multiple first light-emitting groups 22 and multiple second light-emitting groups 23. Each first light-emitting group 22 and each second light-emitting group 23 includes several light-emitting units 21. The multiple light-emitting units 21 in each second light-emitting group 23 are arranged at intervals, which can effectively reduce the overlap of light rays and thus reduce the probability of light spot overlap, which is beneficial to improving the light emission uniformity of the lamp 200. At the same time, the multiple light-emitting units 21 arranged at intervals are also beneficial to improving heat dissipation efficiency and improving the stability and reliability of the lamp 200.

[0047] In this embodiment, to enable the luminaire 200 to meet the needs of various lighting scenarios, the luminous parameters of the first light-emitting group 22 and the second light-emitting group 23 are different. Therefore, when the first light-emitting group 22 and the second light-emitting group 23 are lit simultaneously, the light-emitting module 100 can form at least two different light effects to enrich the light output effect of the luminaire 200. The luminous parameters may specifically include at least one of brightness, color, and color temperature. For example, the first light-emitting group 22 can emit white light, and the second light-emitting group 23 can emit red, blue, or other colored light. Alternatively, the first light-emitting group 22 may have a higher color temperature, emitting a cooler white light, while the second light-emitting group 23 may have a lower color temperature, emitting a warmer yellow or orange light.

[0048] As a specific example, the first light-emitting group 22 may include a plurality of first LED beads 221 and a plurality of second LED beads 222, which are arranged alternately in sequence. The first LED beads 221 and the second LED beads 222 are monochromatic LED beads, and the light emitted by them can be white light. The color temperatures of the first LED beads 221 and the second LED beads 222 may be different; for example, one may have a higher color temperature and emit cooler white light, thus meeting the user's needs in different scenarios. The second light-emitting group 23 may include a plurality of colored LED beads, which are spaced apart to form decorative light. In other embodiments, the first light-emitting group 22 may also include a plurality of dual-color-temperature monochromatic LED beads. The luminaire 200 may also include a controller electrically connected to the plurality of dual-color-temperature monochromatic LED beads, which can control the dual-color-temperature monochromatic LED beads to display different color temperatures in different usage environments to meet the user's needs.

[0049] It is understood that the light emission parameters may also include flicker frequency, beam angle, etc., and this embodiment does not limit this. In some embodiments, the first light emission group 22 may also emit colored light, and the second light emission group 23 may also emit white light, which can be set according to actual usage requirements. In order to further improve the light emission uniformity of the lamp 200, in this embodiment, multiple light emission units 21 of the first light emission group 22 are arranged around the outer periphery of the second light emission group 23, so that the light generated by the first light emission group 22 can supplement the outer periphery of the second light emission group 23 from multiple directions, avoiding local light intensity being too strong or too weak, reducing abrupt changes in light intensity and shadow areas, and creating a softer and more uniform light emission effect. This embodiment does not limit the form in which the first light emission group 22 surrounds the outer periphery of the second light emission group 23. For example, the first light emission group 22 and the second light emission group 23 are arranged in a concentric ring; or, the second light emission group 23 is arranged in a rectangle, and the first light emission group 22 is arranged in a rectangular ring around the outer periphery of the second light emission group 23; or, the first light emission group 22 is arranged radially around the outer periphery of the second light emission group 23.

[0050] Please see Figure 5Furthermore, in some embodiments, since the second light-emitting group 23 is arranged in a surrounding manner, in order to prevent dark areas from appearing on the inner periphery of the second light-emitting group 23 and affecting the uniformity of light output, the light-emitting module 100 may also include a third light-emitting group 24. The third light-emitting group 24 is disposed on the inner periphery of the second light-emitting group 23, and it is used to supplement the light on the inner periphery of the second light-emitting group 23 to prevent dark areas from appearing on the light spot formed on the designated light-receiving plane. Specifically, the second light-emitting group 23 is arranged around the outer periphery of the third light-emitting group 24, and the first light-emitting group 22 is arranged around the outer periphery of the second light-emitting group 23. The light emission parameters of the third light-emitting group 24 can be the same as those of the first light-emitting group 22. For example, when the color temperature and brightness of the third light-emitting group 24 and the first light-emitting group 22 are the same, the light generated by the lamp 200 is more uniform in color and brightness, which is conducive to forming a more harmonious and uniform light spot effect on the designated light-receiving plane and improving the user's visual experience. In addition, it is also helpful to avoid color differences or brightness differences between the outer and inner peripheries of the second light-emitting group 23, thereby further improving the uniformity of light output of the lamp 200.

[0051] As a specific example, the third light-emitting group 24 may include a third LED 241 and a fourth LED 242, both of which are monochromatic LEDs, emitting white light. The color temperatures of the third LED 241 and the fourth LED 242 may differ; for example, one may have a higher color temperature, emitting a cooler white light, thus meeting user needs in different scenarios. In other embodiments, the third light-emitting group 24 may also include multiple dual-color-temperature monochromatic LEDs, with a controller electrically connected to the dual-color-temperature monochromatic LEDs and capable of controlling the dual-color-temperature monochromatic LEDs to display different color temperatures in different usage environments to meet user needs.

[0052] Please see Figure 2 and Figure 5 In this embodiment, since the first light-emitting group 22 is arranged around the outer periphery of the second light-emitting group 23, the distribution area of ​​the first light-emitting group 22 on the base 10 is larger than that of the second light-emitting group 23. Therefore, when the light is directly emitted, the light spot area formed by the first light-emitting group 22 will be larger than that of the second light-emitting group 23. In order to improve the problem of local overbrightness or underbrightness caused by excessive difference in light spot area and to further improve the uniformity of light emission, in this embodiment, the light generated by the light-emitting component 20 can also be adjusted by the dimming component 30 before being emitted to the designated light-receiving plane to form light spots of approximately the same area.

[0053] Specifically, the dimming element 30 is disposed in the optical path formed by the light-emitting component 20, and it is provided with a lens portion 31. The lens portion 31 and the light-emitting component 20 correspond to each other so that the ratio of the light spot area formed by the first light-emitting group 22 on the designated light-receiving plane and the light spot area formed by the second light-emitting group 23 on the designated light-receiving plane is greater than 0.8 and less than 1.2 (including the endpoints). For example, the ratio of the light spot area formed by the first light-emitting group 22 and the light spot area formed by the second light-emitting group 23 can be 0.9, 1, 1.1, etc., and this embodiment does not impose specific limitations on this. That is, the light spot area formed by the first light-emitting group 22 and the light spot area formed by the second light-emitting group 23 are approximately the same, which can avoid the problem of uneven brightness and color temperature distribution of light caused by excessive difference in light spot area, improve the light emission uniformity of the light-emitting module 100, and thus improve the overall light emission effect, providing users with a more comfortable and natural visual experience.

[0054] More specifically, the lens 31 is used to deflect the light from the light-emitting component 20 at an angle so as to reduce the light spot formed by the first light-emitting group 22 or to enlarge the light spot formed by the second light-emitting group 23. The lens 31 can correspond to the first light-emitting group 22 or the second light-emitting group 23. This embodiment does not impose any specific limitations on this.

[0055] Please see Figure 6 and Figure 7 As a specific example, the lens section 31 can be a diffuser lens 311, such as a concave lens. The diffuser lens 311 is located in the optical path formed by the second light-emitting group 23. It is used to increase the emission angle of the second light-emitting group 23, which has a smaller distribution range. This increases the area of ​​the light spot formed when the second light-emitting group 23 emits light at a larger emission angle, thereby making the area of ​​the light spot formed by the second light-emitting group 23 on the designated light-receiving plane approximately the same as the area of ​​the light spot formed by the first light-emitting group 22 on the designated light-receiving plane, thus improving the uniformity of light emission. This embodiment does not limit the specific value of the emission angle and can be set according to actual use. Furthermore, the diffuser lens 311 can also be provided with a light-uniforming structure to further improve the uniformity of the light spot distribution.

[0056] Please see Figure 8 and Figure 9 As another specific example, in some embodiments, the lens portion 31 can also be a converging lens 312, such as a convex lens. The converging lens 312 is located in the optical path formed by the first light-emitting group 22, and it is used to reduce the emission angle of the second light-emitting group 23, which has a larger distribution area. As a result, when the first light-emitting group 22 emits at a smaller emission angle, the corresponding light spot area formed is also reduced. This makes the light spot area formed by the first light-emitting group 22 on the specified light-receiving plane approximately the same as the light spot area formed by the second light-emitting group 23 on the specified light-receiving plane, thereby improving the uniformity of light emission.

[0057] Please see Figure 10 and Figure 11 As another example, the lens section 31 may simultaneously include a diffuser lens 311 and a converging lens 312, with the diffuser lens 311 and converging lens 312 spaced apart. The diffuser lens 311 is located in the optical path formed by the second light-emitting group 23, and the converging lens 312 is located in the optical path formed by the first light-emitting group 22. By setting the diffuser lens 311 and the converging lens 312, the emission angles of the first light-emitting group 22 and the second light-emitting group 23 can be adjusted simultaneously, so that the light spot area formed by the first light-emitting group 22 and the light spot area formed by the second light-emitting group 23 are approximately the same, thereby improving the uniformity of light emission. Furthermore, based on making the light spot areas formed by the first light-emitting group 22 and the second light-emitting group 23 approximately the same, the light emission areas of the two can be adjusted, for example, by increasing or decreasing the overall light spot area after their superposition to meet various user needs.

[0058] It should be noted that the emission angle of the first light-emitting group 22 after adjustment by the dimming component 30 and the emission angle of the second light-emitting group 23 after adjustment by the dimming component 30 can be the same or different. The purpose of dimming by the dimming component 30 is to make the light spot area formed by the first light-emitting group 22 and the second light-emitting group 23 approximately the same. That is, the emission angles of the first light-emitting group 22 and the second light-emitting group 23 after adjustment can be different, but the light emission range covered by the adjusted emission angles is approximately the same. The specific value of the emission angle can be set according to the actual usage requirements.

[0059] It is understood that when the light-emitting module 100 includes a third light-emitting group 24, the lens section 31 can also be located in the optical path formed by the third light-emitting group 24 so that the light spot area formed by the third light-emitting group 24 on the designated light-receiving plane is approximately the same as the light spot area of ​​the first light-emitting group 22 and the light spot area of ​​the second light-emitting group 23. This embodiment does not limit the specific type of the lens section 31 located on the third light-emitting group 24. For example, when the distribution area of ​​the third light-emitting group 24 on the base 10 is large, the lens section 31 can be a converging lens 312 to reduce the emission angle of the third light-emitting group 24; when the distribution area of ​​the third light-emitting group 24 on the base 10 is small, the lens section 31 can be a diffusing lens 311 to increase the emission angle of the third light-emitting group 24. The configuration can be tailored to actual usage requirements.

[0060] In this embodiment, the specific position of the dimming element 30 in the optical path formed by the light-emitting component 20 is not limited. For example, the dimming element 30 can be spaced apart from the light-emitting component 20 so that the lens part 31 and the light-emitting unit 21 are spaced apart. The dimming element 30 can also be integrally disposed with the light-emitting component 20 so that the lens part 31 is encapsulated on the surface of the light-emitting unit 21.

[0061] Please see Figure 12As an example, the dimming element 30 and the light-emitting component 20 are integrated to reduce the overall size of the light-emitting module 100 and lower production costs. Specifically, there can be multiple lens sections 31, which together form the body of the dimming element 30. When the lens section 31 includes a converging lens 312, the multiple lens sections 31 correspond one-to-one with the multiple light-emitting units 21 in the first light-emitting group 22. That is, each lens section 31 is encapsulated on the surface of a corresponding light-emitting unit 21, so that the light generated by the multiple light-emitting units 21 in the first light-emitting group 22 is emitted through the lens section 31 to the designated light-receiving plane or the light-emitting lens 202, ensuring the dimming reliability of the dimming element 30. When the lens section 31 includes a diffuser lens 311, the multiple lens sections 31 correspond one-to-one with the multiple light-emitting units 21 in the second light-emitting group 23. That is, each lens section 31 is encapsulated on the surface of a corresponding light-emitting unit 21.

[0062] By encapsulating multiple lens portions 31 onto the surface of corresponding light-emitting units 21, the overall size of the light-emitting module 100 can be reduced, resulting in a more compact structure and lower production costs. Furthermore, it allows for more complete collection and utilization of the light emitted by the light-emitting units 21, improving light utilization efficiency. Simultaneously, since each lens portion 31 corresponds to a specific light-emitting unit 21, if the light-emitting unit 21 and its corresponding lens portion 31 in the first light-emitting group 22 or the second light-emitting group 23 are damaged, the other light-emitting units 21 and lenses can still function normally, reducing maintenance time and costs. It should be noted that "integrated installation" can mean that the lens portion 31 and the light-emitting unit 21 are integrally injection molded, or that the lens portion 31 is detachably mounted on the light-emitting unit 21. For example, the surface of the light-emitting unit 21 may have a mounting portion for accommodating the lens portion 31.

[0063] Please refer to it again. Figure 11 As another example, the dimming element 30 can be spaced apart from the light-emitting component 20 to separate the lens portion 31 from the light-emitting unit 21. Specifically, the dimming element 30 includes a body portion 32 and a lens portion 31, with the lens portion 31 disposed on the body portion 32. In this embodiment, the body portion 32 is located in the optical path formed by the light-emitting component 20 and is used to mount the lens portion 31. The body portion 32 can be spaced apart from the light-emitting side of the light-emitting component 20, and the body portion 32 is light-transmitting, so that some light can be emitted through the body portion 32 to a designated light-receiving plane or emitted to the light-emitting lens 202 and then emitted to the designated light-receiving plane. The body portion 32 can be at least partially flat to facilitate the mounting of the lens portion 31. In this embodiment, the body portion 32 includes a flat plate portion 322 and a connecting portion 321, with the connecting portion 321 connected to the base 10. The body portion 32 and the light-emitting side of the light-emitting component 20 are opposite to and spaced apart, and the body portion 32 and the connecting portion 321 form a groove structure, in which the light-emitting component 20 is disposed.

[0064] In some embodiments, the lens portion 31 is disposed on the surface of the body portion 32. Specifically, it can be the surface of the body portion 32 facing the light-emitting component 20 or the surface of the body portion 32 away from the light-emitting component 20. This embodiment does not impose specific limitations on this. In some embodiments, the number of lens portions 31 can be one. The lens portion 31 can be located in the optical path of a first light-emitting group 22 or in the optical path of a second light-emitting group 23, so that one lens portion 31 corresponds to multiple light-emitting units 21 in the first light-emitting group 22 or one lens portion 31 corresponds to multiple light-emitting units 21 in the second light-emitting group 23. That is, multiple light-emitting units 21 in the first light-emitting group 22 or multiple light-emitting units 21 in the second light-emitting group 23 all emit from the same lens portion 31. More specifically, as an example, the lens portion 31 can be a surrounding and continuous convex lens, which is located in the optical path of the first light-emitting group 22 so that multiple light-emitting units 21 in the first light-emitting group 22 all emit from the convex lens. The lens section 31 can also be a concave lens that surrounds and continues, located in the optical path of the second light-emitting group 23 so that the multiple light-emitting units 21 in the second light-emitting group 23 all emit light from the concave lens.

[0065] Please see Figure 10 In this embodiment, there are multiple lens sections 31, which are disposed on the flat plate section 322 and spaced apart from each other. Each lens section 31 corresponds one-to-one with a light-emitting unit 21. That is, each light-emitting unit 21 corresponds to an independent lens section 31, and each lens section 31 can adjust the light emission angle according to the position of the corresponding light-emitting unit 21 to further improve the uniformity of light emission. For example, the multiple lens sections 31 may include multiple convex lenses, which correspond one-to-one with the multiple light-emitting units 21 in the first light-emitting group 22. Alternatively, the multiple lens sections 31 may include multiple concave lenses, which correspond one-to-one with the multiple light-emitting units 21 in the second light-emitting group 23.

[0066] Please refer to it again. Figure 2To further improve the uniformity of light emission from the light-emitting module 100, in some embodiments, the light-emitting module 100 may further include a light-mixing component 40. The light-mixing component 40 is used to mix light to avoid color and brightness boundaries in the light spot formed by the light-emitting component 20. The light-mixing component 40 is connected to the base 10 and is at least partially disposed on the side of the dimming component 30 away from the light-emitting component 20. The light-mixing component 40 is located in the light path formed by the light-emitting component 20. As an example, when the first light-emitting group 22 and the second light-emitting group 23 emit light simultaneously, the first light-emitting group 22 can emit white light, and the second light-emitting group 23 can emit colored light. The light formed by the first light-emitting group 22 and the second light-emitting group 23 is dimmed by the dimming component 30 and then emitted to the light-mixing component 40 for mixing, making the color distribution of the mixed light more uniform, thereby avoiding color separation of the emitted light. The light-mixing component 40 also has a mounting groove 41, which is disposed on the side facing the light-emitting component 20. Specifically, the inner wall of the light mixing component 40 defines a mounting groove 41, in which the light-emitting component 20 and the dimming component 30 are both disposed. More specifically, the light mixing component 40 can be bowl-shaped and can be fastened onto the base 10, thereby fully mixing the emitted light from the light-emitting component 20.

[0067] By incorporating the light mixing element 40, not only can color and brightness boundaries be avoided between the light spots of the first light-emitting group 22 and the second light-emitting group 23, thus further improving the uniformity of light output, but the light mixing element 40 can also effectively guide light to a specific area of ​​the designated light-receiving plane, reducing light waste and energy loss and improving light efficiency. Furthermore, it also protects the light-emitting component 20 and the dimming element 30, preventing moisture, dust, and other impurities from entering the light-emitting module 100, ensuring good light output performance of the light-emitting module 100.

[0068] Please see Figure 13 and Figure 4That is, in some embodiments, the light generated by the light-emitting component 20 is emitted sequentially through the dimming component 30 and the mixing component 40, and after being dimmed by the light-emitting lens 202, it is emitted to the outside world and finally emitted to the designated light-receiving plane. After the first light-emitting group 22 and the second light-emitting group 23 of the light-emitting component 20 are dimmed by the lens portion 31 on the dimming component 30, the light generated by the first light-emitting group 22 and the light generated by the second light-emitting group 23 form light spots of approximately the same area at the mixing component 40 with the adjusted emission angle. The light spots formed by the two are then transmitted to the light-emitting lens 202, which is coaxially arranged with the light-emitting module 100. Since the light-emitting lens 202 is symmetrical about the central axis O1 and coaxial with the light-emitting module 100, the emission angle formed by the light-emitting module 100 at any position of the light-emitting lens 202 is the same, which can ensure that the light spots of the first light-emitting group 22 and the second light-emitting group 23 finally emitted to the designated light-receiving plane are approximately the same, thereby improving the light emission uniformity of the lamp 200. Similarly, when the light-emitting module 100 includes a third light-emitting group 24, the third light-emitting group 24 also has the same light-emitting process as the first light-emitting group 22. To save space, this embodiment will not describe it again. For details, please refer to the light-emitting process of the first light-emitting group 22.

[0069] In summary, this embodiment provides a light-emitting module 100, which includes a base 10, a light-emitting component 20, and a dimming component 30. The light-emitting component 20 has multiple light-emitting units 21 divided into multiple first light-emitting groups 22 and multiple second light-emitting groups 23. The light-emitting parameters of the first light-emitting groups 22 and the second light-emitting groups 23 are different, thereby enabling the same light-emitting module 100 to produce various different light-emitting effects to meet diverse lighting needs. Furthermore, the dimming element 30 is disposed in the optical path of the light-emitting component 20. The lens portion 31 of the dimming element 30 corresponds to the light-emitting component 20 to adjust the light spot area formed by the first light-emitting group 22 and the second light-emitting group 23, so that the ratio of the light spot area formed by the first light-emitting group 22 on the specified light-receiving plane to the light spot area formed by the second light-emitting group 23 is greater than 0.8 and less than 1.2. That is, the light spot area formed by the first light-emitting group 22 and the light spot area formed by the second light-emitting group 23 are approximately the same. This can effectively avoid the problem of uneven brightness and color temperature distribution caused by excessive difference in light spot area, improve the light emission uniformity of the light-emitting module 100, and thus improve the overall light emission effect, providing users with a more comfortable and natural visual experience.
