[0008] In some embodiments, the first light-emitting unit includes multiple first light-emitting chips.

[0011] In some embodiments, the plurality of second light-emitting chips include a first color light chip, a second color light chip, a third color light chip, and a fourth color light chip, and the arrangement of the first color light chip, the second color light chip, the third color light chip, and the fourth color light chip included in adjacent second light-emitting units is different.

[0012] In some embodiments, the first light emitting unit is a monochromatic light emitting unit.

[0013] In some embodiments, the luminous colors of the first color optical chip, the second color optical chip, the third color optical chip and the fourth color optical chip are different; the first color optical chip is a red light chip, a green light chip, a blue light chip or a white light chip; the second color optical chip is a red light chip, a green light chip, a blue light chip or a white light chip; the third color optical chip is a red light chip, a green light chip, a blue light chip or a white light chip; the fourth color optical chip is a red light chip, a green light chip, a blue light chip or a white light chip.

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0028] See Figure 1 and Figure 2 , an embodiment of the present application provides a light source module 100 , which may be a beam light, a stage light or other light source modules 100 .

[0029] In some embodiments, the light source module 100 includes a heat dissipation substrate 110 , a plurality of light emitting components 120 and a lens component 130 . The plurality of light emitting components 120 are disposed on the heat dissipation substrate 110 . Light emitted by the plurality of light emitting components 120 can be emitted outside the light source module 100 through the lens component 130 .

[0030] In some embodiments, the heat dissipation substrate 110 may be a ceramic substrate, which helps the heat dissipation substrate 110 effectively dissipate heat for the multiple light-emitting components 120. Ceramics have good thermal stability and a low coefficient of thermal expansion, which helps the heat dissipation substrate 110 maintain stable physical properties and resist deformation even in high-temperature environments. Furthermore, the ability of the heat dissipation substrate 110 to dissipate heat for multiple light-emitting components 120 helps reduce the number of heat dissipation substrates 110 and lower the cost of the light source module 100.

[0031] In some embodiments, the heat dissipation substrate 110 may be a PCB board, and the heat dissipation substrate 110 may provide electrical input for the light emitting component 120 .

[0032] In some embodiments, a plurality of light-emitting components 120 are arrayed on the heat dissipation substrate 110 , which helps the plurality of light-emitting components 120 form an orderly layout combination.

[0033] In some embodiments, multiple light-emitting components 120 can be arranged in an array along multiple rows and columns, which helps the light source module 100 expand the light-emitting area in the row direction X and the column direction Y. For example, multiple light-emitting components 120 can be arrayed to form a square, rectangle, quadrilateral, prism, circle, ellipse or other shapes.

[0034] See Figure 2 In some embodiments, two adjacent rows of light-emitting components 120 can be staggered along the column direction Y, and two adjacent columns of light-emitting components 120 can be staggered along the row direction X, which helps to form multiple light-emitting components 120 into quadrilaterals, prisms, circles, ellipses, and other forms.

[0035] See Figure 3 In some embodiments, two adjacent rows of light-emitting components 120 can be aligned along the column direction Y, and two adjacent columns of light-emitting components 120 can be aligned along the row direction X, which helps to form multiple light-emitting components 120 into a square, rectangle, or other form.

[0036] In some embodiments, each light-emitting assembly 120 may include a first light-emitting unit 121 and a second light-emitting unit 122, which are adjacently disposed. Adjacently disposed may mean that the spacing between the first light-emitting unit 121 and the second light-emitting unit 122 is zero or very small, and the spacing between the first light-emitting unit 121 and the second light-emitting unit 122 may be less than or equal to the spacing between two adjacent light-emitting assemblies 120. In terms of space compactness and the practicality of adjusting the collimating lens, the smaller the spacing, the better.

[0037] See Figure 4 In some embodiments, the first light-emitting unit 121 may include at least one first light-emitting chip 1211. When the first light-emitting unit 121 includes only one first light-emitting chip 1211, the first light-emitting chip 1211 may be a monochromatic light-emitting chip. For example, the first light-emitting chip 1211 may be a white light-emitting chip, so that the light source module 100 can emit white light through the first light-emitting units 121 of the multiple light-emitting assemblies 120. When the first light-emitting unit 121 includes multiple first light-emitting chips 1211, the light-emitting colors of the multiple first light-emitting chips 1211 are different, so that the light source module 100 can emit colored light through the first light-emitting units 121 of the multiple light-emitting assemblies 120.

[0038] In some embodiments, when the first light emitting unit 121 includes multiple first light emitting chips 1211 , in the same light emitting assembly 120 , the multiple first light emitting chips 1211 of the first light emitting unit 121 are arranged on the same side of the second light emitting unit 122 .

[0039] In some embodiments, the rotation angles of two adjacent first light-emitting units 121 relative to their own light-emitting centers are different, which helps to improve the uniformity of the light emitted by the light source module 100 .

[0040] In some embodiments, the arrangements of the multiple first light-emitting chips 1211 of two adjacent first light-emitting units 121 are different, which helps to improve the uniformity of the emitted light of the light source module 100 .

[0041] In some embodiments, the arrangement of the multiple first light-emitting chips 1211 of two adjacent first light-emitting units 121 is different. For example, both first light-emitting units 121 include a first chip, a second chip, a third chip and a fourth chip, and the first chip, second chip, third chip and fourth chip of one first light-emitting unit 121 are arranged in a clockwise direction, and the first chip, second chip, third chip and fourth chip of the other first light-emitting unit 121 are arranged in a counterclockwise direction.

[0042] In some embodiments, the first chip can be a red light chip, a green light chip, a blue light chip or a white light chip; the second chip can be a red light chip, a green light chip, a blue light chip or a white light chip; the third chip can be a red light chip, a green light chip, a blue light chip or a white light chip; the fourth chip can be a red light chip, a green light chip, a blue light chip or a white light chip.

[0043] In some embodiments, when the first light-emitting unit 121 includes seven first light-emitting chips 1211, the seven first light-emitting chips 1211 provide four colors of light: RGBW. There are two chips for white light, and two chips each for two of the following colors: red, green, and blue. However, the brightness of the chips with the same color may vary. In other embodiments, the first light-emitting unit 121 may include eleven first light-emitting chips 1211.

[0044] In some embodiments, the rotation angles of two adjacent first light-emitting units 121 relative to their own light-emitting centers are different. For example, one of the two adjacent first light-emitting units 121 does not rotate relative to its own light-emitting center, and the other first light-emitting unit 121 rotates relative to its own light-emitting center at a set angle, such as 15 degrees, 30 degrees, 90 degrees, or other angles.

[0045] See Figure 4 In some embodiments, the second light emitting unit 122 may include one or more second light emitting chips 1221 .

[0046] The first light emitting chip 1211 emits light of a different color than the second light emitting chip 1221. For example, when the second light emitting unit 122 includes one second light emitting chip 1221, the second light emitting chip 1221 may emit light of one of RGB, and the first light emitting chip 1211 may emit light of another of RGB.

[0047] When the second light-emitting unit 122 includes a plurality of second light-emitting chips 1221, the plurality of second light-emitting chips 1221 of the second light-emitting unit 122 are arranged on the same side of the first light-emitting unit 121 in the same light-emitting assembly 120. This helps achieve a more uniform color distribution across the entire light-emitting area of ​​the light source module 100, thereby improving the uniformity of the light emitted by the light source module 100.

[0048] In some embodiments, the second light-emitting unit 122 may include 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or other numbers of second light-emitting chips 1221 .

[0049] In some embodiments, the plurality of second light-emitting chips 1221 may include a first color light chip 1222, a second color light chip 1223, a third color light chip 1224, and a fourth color light chip 1225. The plurality of second light-emitting chips 1221 are arranged such that the first color light chip 1222, the second color light chip 1223, the third color light chip 1224, and the fourth color light chip 1225 are sequentially arranged along a predetermined direction. Arranging the second light-emitting chips 1221 of different colors in this manner helps achieve a more uniform color distribution within the light-emitting area of ​​the light source module 100, avoiding excessive color concentration or color cast.

[0050] In some embodiments, the setting direction may be clockwise or counterclockwise.

[0051] In some embodiments, the first color optical chip 1222, the second color optical chip 1223, the third color optical chip 1224, and the fourth color optical chip 1225 emit different colors. For example, the first color optical chip 1222 can be a red optical chip, a green optical chip, a blue optical chip, or a white optical chip; the second color optical chip 1223 can be a red optical chip, a green optical chip, a blue optical chip, or a white optical chip; the third color optical chip 1224 can be a red optical chip, a green optical chip, a blue optical chip, or a white optical chip; and the fourth color optical chip 1225 can be a red optical chip, a green optical chip, a blue optical chip, or a white optical chip.

[0052] In some embodiments, when the second light-emitting unit 122 includes seven second light-emitting chips 1221, the seven second light-emitting chips 1221 provide four colors of light: RGBW. There are two chips for white light, and two chips each for two of the following colors: red, green, and blue. However, the brightness of the chips with the same color may vary. In other embodiments, the second light-emitting unit 122 may include eleven second light-emitting chips 1221.

[0053] In some embodiments, the second light-emitting chips 1221 of two adjacent second light-emitting units 122 are arranged differently, which helps to improve the uniformity of the light emitted by the light source module 100 .

[0054] In some embodiments, the rotation angles of two adjacent second light-emitting units 122 relative to their own light-emitting centers are different. For example, one of the two adjacent second light-emitting units 122 does not rotate relative to its own light-emitting center, and the other second light-emitting unit 122 rotates relative to its own light-emitting center at a set angle, such as 15 degrees, 30 degrees, 90 degrees, or other angles.

[0055] In some embodiments, the rotation angle of the second light emitting unit 122 relative to its own light emitting center is different from the rotation angle of the first light emitting unit 121 relative to its own light emitting center, which helps to improve the uniformity of the light emitted by the light source module 100.

[0056] In some embodiments, the number, arrangement, and rotation angle between the first light-emitting chips 1211 in the first light-emitting unit 121 and the second light-emitting chips 1221 in the second light-emitting unit 122 may be the same or different.

[0057] For example Figure 3 As shown, each first light-emitting unit 121 can include a first light-emitting chip 1211, and each second light-emitting unit 122 can include multiple second light-emitting chips 1221 emitting light of different colors. The arrangement of the multiple second light-emitting chips 1221 emitting light of different colors in two adjacent second light-emitting units 122 is different. The first light-emitting unit 121 can emit white light, and the second light-emitting unit 122 can emit colored light.

[0058] For example Figure 5As shown, each first light-emitting unit 121 can include a first light-emitting chip 1211, and each second light-emitting unit 122 can include multiple second light-emitting chips 1221 emitting light of different colors. The arrangement of the multiple second light-emitting chips 1221 emitting light of different colors in two adjacent second light-emitting units 122 is different. In addition, in the same light-emitting assembly 120, the rotation angle of the first light-emitting unit 121 relative to its own light-emitting center is different from the rotation angle of the second light-emitting unit 122 relative to its own light-emitting center. The first light-emitting unit 121 can emit white light, and the second light-emitting unit 122 can emit colored light.

[0059] In some embodiments, in the same light-emitting component 120, the multiple first light-emitting chips 1211 of the first light-emitting unit 121 are arranged on the same side of the second light-emitting unit 122, and the multiple second light-emitting chips 1221 of the second light-emitting unit 122 are arranged on the same side of the first light-emitting unit 121; the multiple first light-emitting chips 1211 of the first light-emitting unit 121 and the multiple second light-emitting chips 1221 of the second light-emitting unit 122 are arranged in the same manner, and the rotation angle of the first light-emitting unit 121 relative to its own light-emitting center is different from the rotation angle of the second light-emitting unit 122 relative to its own light-emitting center.

[0060] For example Figure 6 and Figure 7 As shown, each first light-emitting unit 121 includes a plurality of first light-emitting chips 1211, and the arrangement of the plurality of first light-emitting chips 1211 of two adjacent first light-emitting units 121 is different; each second light-emitting unit 122 may include a plurality of second light-emitting chips 1221 of luminous colors, and the arrangement of the plurality of second light-emitting chips 1221 of two adjacent second light-emitting units 122 is the same, and the two adjacent second light-emitting units 122 do not rotate relative to their own light-emitting centers. Figure 6 As shown, or the rotation angles of two adjacent second light emitting units 122 relative to their own light emitting centers are different as shown in FIG. Figure 7 The first light emitting unit 121 can emit colored light, and the second light emitting unit 122 can emit colored light. The colored light emitted by the first light emitting unit 121 and the second light emitting unit 122 have different color rendering properties, color temperatures, and luminous flux. Figure 6 and Figure 7 The RGBW is only used as an example. Any solution including two different colors embodies the inventive spirit of this embodiment.

[0061] In some embodiments, within a single light-emitting assembly 120, multiple first light-emitting chips 1211 of a first light-emitting unit 121 are arranged on the same side of a second light-emitting unit 122, and multiple second light-emitting chips 1221 of a second light-emitting unit 122 are arranged on the same side of the first light-emitting unit 121. The number of first light-emitting chips 1211 in a single light-emitting assembly 120 differs from the number of second light-emitting chips. Within a single light-emitting assembly 120, the rotation angle of a first light-emitting unit 121 relative to its own light-emitting center differs from the rotation angle of a second light-emitting unit 122 relative to its own light-emitting center.

[0062] For example Figure 8 and Figure 9 As shown, each first light-emitting unit 121 includes a plurality of first light-emitting chips 1211, and the arrangement of the plurality of first light-emitting chips 1211 of two adjacent first light-emitting units 121 is different; each second light-emitting unit 122 may include a plurality of second light-emitting chips 1221, and the arrangement of the plurality of second light-emitting chips 1221 of two adjacent second light-emitting units 122 is the same; in the same light-emitting component 120, the number of first light-emitting chips 1211 of the first light-emitting unit 121 is different from the number of second light-emitting chips 1221 of the second light-emitting unit 122. At least one of the first light-emitting unit 121 and the second light-emitting unit 122 may rotate or not rotate relative to its own light-emitting center. For example, two adjacent second light-emitting units 122 do not rotate relative to their own light-emitting centers. Figure 8 As shown, or the rotation angles of two adjacent second light emitting units 122 relative to their own light emitting centers are different as shown in FIG. Figure 9 The first light emitting unit 121 can emit colored light, and the second light emitting unit 122 can emit colored light. The colored light emitted by the first light emitting unit 121 and the second light emitting unit 122 have different color rendering properties, color temperatures, and luminous flux. Figure 8 and Figure 9 The RGBW in the figure is only used as an example. As long as the scheme includes two different colors, it embodies the inventive spirit of this embodiment. One of the first light-emitting unit 121 and the second light-emitting unit 122 can include one of four, seven or twelve colors of light, and the other light-emitting unit can include another of four, seven or twelve colors of light.

[0063] In some embodiments, the first light-emitting chip 1211 may be an LED light-emitting chip; the second light-emitting chip 1221 may be an LED light-emitting chip. In this way, the LED light-emitting chip is small in size and light in weight, and a more compact and lightweight product can be designed, which is easy to install in a small space. The LED light-emitting chip starts quickly, does not require preheating, and has almost no flicker during operation, which is helpful for application scenarios that require frequent switching or have high requirements for light stability. The LED light-emitting chip can more efficiently convert electrical energy into light energy, significantly reducing energy consumption. In addition, the LED light-emitting chip has good weather resistance and can operate stably in a wide temperature range. It is not affected by low or high temperatures and is suitable for a variety of indoor and outdoor environments. In other embodiments, the first light-emitting chip 1211 may be a laser chip; the second light-emitting chip 1221 may be a laser chip.

[0064] See Figure 1 In some embodiments, the lens assembly 130 may include a plurality of lens elements 131. The lens assembly 130 is adjustably disposed relative to the light emitting assembly 120 so that the lens elements 131 can be selectively positioned in the light emitting path of the first light emitting unit 121 or the second light emitting unit 122, thereby enabling the light source module 100 to switch between different lighting modes. For example, when the lens element 131 is positioned in the light emitting path of the first light emitting unit 121, the first light emitting unit 121 emits white light, and the light source module 100 can emit white light; and when the first light emitting unit 121 emits colored light, the light source module 100 can emit colored light. For another example, when the lens element 131 is positioned in the light emitting path of the second light emitting unit 122, the second light emitting unit 122 emits colored light, and the light source module 100 can emit colored light. This eliminates the need to replace the entire light source module 100 when switching between white light and colored light, resulting in lower costs and higher operating efficiency.

[0065] In some embodiments, the light source module 100 may further include a light homogenizer 140, which is located in the light path of the lens assembly 130 and is used to homogenize the light emitted by the lens assembly 130. In this way, the light homogenizer 140 helps improve the uniformity of the light, helps reduce the problem of localized overbrightness or overdarkness in the light emitted by the light source module 100, and makes the light softer and more comfortable.

[0066] In some embodiments, the light homogenizing device 140 may include a compound eye lens or a diffuser. The compound eye lens can split and reintegrate the incident light beam through a plurality of tiny lens structures, and each microlens can independently regulate a small portion of the light, thereby achieving fine homogenization of the light, making the outgoing light more uniform, and helping to improve the imaging quality. The diffuser can scatter light through the microstructure inside the material, so that the light can be evenly dispersed in multiple directions after being emitted, which can effectively expand the coverage of the light and reduce the central hot spot. In this way, both the compound eye lens and the diffuser help to disperse and mix the outgoing light of the lens assembly 130, help to reduce dark areas, and make the brightness distribution of the outgoing light of the light source module 100 more uniform and consistent, which helps to improve the overall softness and comfort.

[0067] In some embodiments, when the light homogenizing device 140 includes a fly-eye lens, the light homogenizing device 140 may be a single fly-eye lens or a double fly-eye lens.

[0068] In some embodiments, the light source module 100 may further include a condenser lens 150, which is located in the light output path of the light homogenizing device 140 to direct light out of the light output lens. In this way, the condenser lens 150 can concentrate and guide the homogenized light, directing the light more concentratedly toward the light output lens, thereby reducing light loss and ensuring that more light is effectively utilized.

[0069] In some embodiments, the condenser lens 150 may be a biconvex lens, a plano-convex lens, or other types.

[0070] In this application, unless otherwise expressly specified or limited, terms such as "mounted" and "connected" should be interpreted broadly.
