[0022] 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.

[0023] 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.

[0024] See Figure 1 and Figure 2 An embodiment of the present application provides a light source module 100, which includes a heat dissipation substrate 110, a plurality of light-emitting units 120 and a collecting lens group 130. The plurality of light-emitting units 120 are arranged on the heat dissipation substrate 110, and the light emitted by the plurality of light-emitting units 120 can be emitted to the outside of the light source module 100 through the collecting lens group 130.

[0025] The collecting lens assembly 130 includes a plurality of lens units 131, which are arranged in a one-to-one correspondence with the light output paths of the plurality of light-emitting units 120. The lens units 131 are used to collect the light emitted by the light-emitting units 120. The collecting lens assembly 130 helps to enhance the directionality and intensity of the light emitted by the light-emitting units 120 and reduce the impact of stray light on image quality.

[0026] 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 units 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 heat dissipation substrate 110 can dissipate heat for multiple light-emitting units 120, which helps reduce the number of heat dissipation substrates 110 and lower the cost of the light source module 100.

[0027] 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 unit 120 .

[0028] In some embodiments, the light emitting unit 120 may be disposed on the heat dissipation substrate 110 via a heat sink 140 , so that the heat sink 140 can more effectively transfer the heat of the light emitting unit 120 to the surrounding environment and the heat dissipation substrate 110 .

[0029] In some embodiments, a plurality of light emitting units 120 are arrayed on the heat dissipation substrate 110 , which helps the plurality of light emitting units 120 form an orderly layout combination.

[0030] In some embodiments, multiple light-emitting units 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 units 120 can be arrayed in the form of a square, rectangle, quadrilateral, prism, circle, ellipse or other shapes.

[0031] In some embodiments, any two adjacent rows of light-emitting units 120 can be staggered along the column direction Y, and any two adjacent columns of light-emitting units 120 can be staggered along the row direction X, which helps to form multiple light-emitting units 120 into quadrilaterals, prisms, circles, ellipses, etc.

[0032] In some embodiments, any two adjacent rows of light emitting units 120 can be aligned along the column direction Y, and any two adjacent columns of light emitting units 120 can be aligned along the row direction X, which helps to form multiple light emitting units 120 into a square, rectangle, or other form.

[0033] See Figure 3 In some embodiments, each light-emitting unit 120 includes at least one red chip 121 and one green chip 122, and the red chip 121 and the green chip 122 are adjacent to each other in each light-emitting unit 120. Adjacent can mean that the spacing between the chips is zero or very small, or the spacing between the chips can be less than or equal to the spacing between two adjacent light-emitting units 120. From the perspective of space compactness and the practicality of adjusting the collimating lens, the smaller the spacing, the better.

[0034] In some embodiments, the adjacent positions of the red light chip 121 and the green light chip 122 can be distributed in various ways, for example Figure 3 As shown, the red light chip 121 and the green light chip 122 may be adjacent to each other in the row direction. Figure 4 As shown, the red light chip 121 and the green light chip 122 may be adjacent to each other in the column direction.

[0035] The adjacent arrangement design of the red light chip 121 and the green light chip 122 in the embodiment of the present application helps to optimize the color uniformity after the light of the two is mixed, and also helps to optimize the color uniformity after the light of the red light chip 121 (or the green light chip 122) is mixed with the light of other chips. The light-emitting chips of different colors work together to provide a richer color selection, and this multi-color combination helps to achieve a more natural and realistic lighting effect, which in turn helps to improve the color performance of the overall light source module 100, and is also beneficial to improve the arrangement flexibility of other color chip settings.

[0036] In some embodiments, each light-emitting unit 120 further includes an auxiliary chip 124 for emitting auxiliary light. Thus, the auxiliary chip 124 helps the light source module 100 produce a wider range of colors. Combining chips of different colors helps adjust the overall color temperature and color rendering index of the light source module 100, enhancing color expression and improving lighting effects while also meeting the demand for color diversity in various application scenarios.

[0037] In some embodiments, the auxiliary chip 124 is arranged adjacent to the red light chip 121 or the green light chip 122 , which helps to improve the uniformity of the mixing of different colors of light, helps to reduce color difference, and makes the final output mixed light more natural and uniform.

[0038] In some embodiments, each light emitting unit 120 may include one or more auxiliary chips 124 .

[0039] In some embodiments, each light-emitting unit 120 further includes a first light-emitting chip 123. The light-emitting color of the first light-emitting chip 123 is different from the light-emitting color of the red light chip 121, the green light chip 122, and the auxiliary chip 124. Thus, the first light-emitting chip 123 helps the light source module 100 produce a wider range of colors. The combination of chips of different colors helps adjust the overall color temperature and color rendering index of the light source module 100, which not only helps enhance color expression and improve lighting effects, but also helps meet the demand for color diversity in various application scenarios.

[0040] In some embodiments, the first light emitting chip 123 is arranged adjacent to the red light chip 121 or the green light chip 122 , which helps to improve the uniformity of the mixing of different colors of light, helps to reduce color difference, and makes the final output mixed light more natural and uniform.

[0041] In some embodiments, the first light emitting chip 123 is a blue light chip, an amber light chip, an orange light chip, or a yellow light chip.

[0042] In some embodiments, the auxiliary chip 124 and the first light-emitting chip 123 are both located on the same side of the line connecting the light-emitting centers of the red light chip 121 and the green light chip 122. This helps to concentrate the light of different colors for mixing. This layout helps to reduce uneven color distribution, provides a more continuous and smooth spectrum, and helps to enhance color rendering performance, thereby helping to improve the color uniformity and consistency of the overall output light.

[0043] In some embodiments, the auxiliary chip 124 is a white light chip, and the white light emitted by the auxiliary chip 124 has a higher color rendering index, which helps to improve the total brightness of the entire light source module 100. Since white light is a mixture of multiple colors of light, white light can make up for the deficiencies of red light, green light and other colors of light, and help provide brighter and more uniform lighting.

[0044] See Figure 5 In some embodiments, at least two adjacent light-emitting units 120 have different rotation angles relative to the light-emitting center of the light source module 100, which helps to change the relative positions of the chips in the two adjacent light-emitting units 120, thereby helping to optimize the mixing effect of different colors of light, which helps to reduce color unevenness and make the color output of the entire light source module 100 more uniform.

[0045] In some embodiments, at least two adjacent light-emitting units 120 have different rotation angles relative to their own light-emitting centers, which also helps to change the relative positions of the chips within the two adjacent light-emitting units 120, thereby helping to optimize the mixing effect of different colors of light, which helps to reduce color unevenness and make the color output of the entire light source module 100 more uniform.

[0046] In some embodiments, the chips of at least two adjacent light-emitting units 120 are arranged differently, which helps to form a more diverse light mixing mode in the entire light source module 100, which helps to reduce the color unevenness that may be caused by a single arrangement, thereby helping to improve the color uniformity of the overall lighting.

[0047] Among them, the arrangement of the chips between two adjacent light-emitting units 120 is different. For example, the red light chip 121, green light chip 122, first light-emitting chip 123, auxiliary chip 124, etc. of one light-emitting unit 120 are arranged in a clockwise direction, and the red light chip 121, green light chip 122, first light-emitting chip 123, auxiliary chip 124, etc. of the other light-emitting unit 120 are arranged in a counterclockwise direction.

[0048] In some embodiments, at least two adjacent light-emitting units 120 have different numbers of chips. Different numbers of chips help produce different proportions of color mixing, help reduce color unevenness that may be caused by a single configuration, and help improve the uniformity and consistency of the overall color output.

[0049] Among them, the number of chips of two adjacent light-emitting units 120 is different. For example, one of the light-emitting units 120 has a red light chip 121, a green light chip 122, a first light-emitting chip 123, and an auxiliary chip 124; the other light-emitting unit 120 has a red light chip 121, a green light chip 122, a first light-emitting chip 123, and two auxiliary chips 124.

[0050] In some embodiments, the lens unit 131 may include a first collimating lens 132 and a second collimating lens 133, which are sequentially arranged in the light output path of the light emitting unit 120. In this way, the use of two consecutive collimating lenses helps further enhance the directionality of the emitted light. The first collimating lens 132 initially corrects the light path, while the second collimating lens 133 further refines and optimizes the direction of the light, helping to form a more parallel and concentrated light beam. The combined use of the two collimating lenses helps improve the uniformity and consistency of the color of the overall illumination.

[0051] In some embodiments, the radius of the second collimating lens 133 is greater than the radius of the first collimating lens 132 , so that the light spot of the light emitted by the light emitting unit 120 can be reduced after passing through the first collimating lens 132 and the second collimating lens 133 in sequence.

[0052] In some embodiments, the light incident surface of the first collimating lens 132 may be a flat surface or a convex surface, and the light emitting surface of the first collimating lens 132 may be a convex surface.

[0053] In some embodiments, the light incident surface of the second collimating lens 133 may be a flat surface or a convex surface, and the light emitting surface of the second collimating lens 133 may be a convex surface.

[0054] See Figure 1 In some embodiments, the light source module 100 further includes a condenser lens 150, which is located in the light path of the collection lens assembly 130 and is used to converge the light beam. In this way, the condenser lens 150 can concentrate and guide the uniformly treated light, directing the light more concentratedly in the light-emitting direction, helping to reduce light loss and ensure that more light is effectively utilized.

[0055] In some embodiments, the condensing lens 150 may be a plano-convex lens. For example, the light incident surface of the condensing lens 150 may be a convex surface, and the light emitting surface of the condensing lens 150 may be a flat surface.
