[0038] 1 to 3 , an embodiment of the present application provides a light-emitting element 100 . By arranging and packaging different light-emitting chips in a certain manner and density to form a light-mixing unit, the different light-emitting chips can mix light, thereby eliminating the need for a light-mixing cavity, simplifying the structure of the light-emitting module, reducing light loss, and improving light efficiency.

[0039] Specifically, the light emitting element 100 of this embodiment includes a substrate 10 and a chip module 20 disposed on the substrate 10. The chip module 20 includes a warm light chip 211, a cold light chip 212, and an RGB chip group 22.

[0042] In the light-emitting element 100, the RGB light mixing unit 201 and the cold and warm light mixing unit 202 are concentrically arranged, and the multiple RGB light mixing units 201 and the multiple cold and warm light mixing units 202 are arranged at intervals and staggered, and the multiple RGB light mixing units 201 and the multiple cold and warm light mixing units 202 are rotationally symmetrical about the center of the chip module 20. In this way, each RGB chip group 22 can mix light with the circumferential warm light chip 211 and the cold light chip 212, so that different light-emitting chips can mix light, thereby eliminating the setting of the mixing cavity in the light source module 1000, simplifying the structure of the light source module 1000, reducing light loss, improving light efficiency, and ensuring the user experience.

[0043] In this embodiment, the chip module 20 is a circular structure as a whole, and a group of RGB chipsets 22 is arranged at the center of the chip module 20 .

[0044] Each RGB chip set 22 in this embodiment includes two red chips 221, one green chip 222, and one blue chip 223. The two red chips 221, one green chip 222, and one blue chip 223 are spaced apart and enclosed to form a square structure. The two red chips 221 are positioned opposite each other, while the green chip 222 and the blue chip 223 are positioned opposite each other.

[0045] One RGB chipset 22 is used as the center of the chip module 20 , that is, the center of the RGB chipset 22 is the center of the chip module 20 .

[0046] Specifically, referring to Figures 4 and 5 , in actual configuration, a center point can be determined on substrate 10, and multiple concentrically arranged annular regions can be arranged on the surface of substrate 10, gradually expanding outward from the center point. The multiple annular regions are multiple first annular regions 101 and multiple second annular regions 102, and the multiple first annular regions 101 and the multiple second annular regions 102 are arranged alternately in sequence.

[0047] A group of RGB chipsets 22 is provided at the center point of the substrate 10, and RGB light mixing units 201 and cold and warm light mixing units 202 are arranged in multiple annular areas respectively, and the multiple RGB light mixing units 201 and the multiple cold and warm light mixing units 202 are alternately arranged in sequence, so that the multiple RGB light mixing units 201 and the multiple cold and warm light mixing units 202 are rotationally symmetric with respect to the center of the chip module 20.

[0048] In this embodiment, RGB light mixing units 201 are arranged at intervals in the first annular area 101, and cold and warm light mixing units 202 are arranged in the second annular area 102, so that the multiple RGB light mixing units 201 and the multiple cold and warm light mixing units 202 are alternately arranged in sequence, and the multiple RGB light mixing units 201 and the multiple cold and warm light mixing units 202 are rotationally symmetric about the center point of the substrate 10.

[0049] Furthermore, multiple RGB chipsets are spaced apart and arranged to form a ring-shaped RGB light mixing unit 201. In this embodiment, the outer contour of the RGB light mixing unit 201 is circular. Warm light chips 211 and cold light chips 212 are adjacently arranged to form a cold and warm chipset group 21. Multiple cold and warm chipsets 21 are spaced apart and arranged to form a ring-shaped cold and warm light mixing unit 202. In this embodiment, the outer contour of the cold and warm light mixing unit 202 is square or circular.

[0050] A plurality of RGB light mixing units 201 and a plurality of cold and warm light mixing units 202 are provided on the substrate 10. The RGB light mixing units 201 and the cold and warm light mixing units 202 are arranged concentrically. The plurality of RGB light mixing units 201 and the plurality of cold and warm light mixing units 202 are arranged at intervals and staggered, so that the plurality of RGB light mixing units 201 and the plurality of cold and warm light mixing units 202 are rotationally symmetrical about the center of the chip module 20.

[0051] Specifically, the RGB chipset 22 positioned at the center of the chip module 20 is the central chipset 220. A set of square-shaped warm and cold light mixing units 202 are arranged at intervals around the periphery of the central chipset 220. This arrangement allows the two red chips 221, one green chip 222, and one blue chip 223 in the RGB chipset serving as the central chipset 220 to mix light with the warm light chip 211 and the cold white light chip circumferentially, achieving a light mixing effect between the chips.

[0052] In this embodiment, on the periphery of the square cold and warm light mixing unit 202, multiple circular RGB light mixing units 201 and multiple circular cold and warm light mixing units 202 are concentrically and spaced apart, and the center of the multiple circular RGB light mixing units 201 and the multiple circular cold and warm light mixing units 202 is the center of the RGB chipset serving as the central chipset 220.

[0053] When multiple circular RGB light mixing units 201 and multiple circular cold and warm light mixing units 202 are concentrically and spaced apart, the RGB light mixing units 201 and the cold and warm light mixing units 202 are staggered, and the multiple RGB light mixing units 201 and the multiple cold and warm light mixing units 202 on the substrate 10 are rotationally symmetrical about the center of the chip module 20.

Such an arrangement enables each multi-color chip to mix light with the warm light chip 211 and the cold light white chip in its circumferential direction to achieve the light mixing effect of the light-emitting device, thereby eliminating the setting of the mixing cavity and simplifying the structure of the light-emitting device.

[0055] Furthermore, in conjunction with FIG3 , on the substrate 10 of this embodiment, all RGB light mixing units 201 include a plurality of independently arranged first light mixing units 2201 and second light mixing units 2202 , and the first light mixing units 2201 and the second light mixing units 2202 each include a plurality of RGB chip groups that are spaced apart and arranged to form a circumferentially closed structure.

[0056] In this embodiment, the radial sizes of the plurality of first light mixing units 2201 and the plurality of second light mixing units 2202 are all different, that is, all the RGB light mixing units 201 on the substrate 10 include a plurality of first light mixing units 2201 with different diameters and a plurality of second light mixing units 2202 with different diameters.

[0057] In this embodiment, a group of cold and warm chip groups 21 is provided between two adjacent RGB chip groups in each first light mixing unit 2201, so that the first light mixing unit 2201 and the multiple cold and warm chip groups 21 constitute a first light mixing sub-module 2011; and a warm light chip 211 or a cold light chip 212 is provided between two adjacent RGB chip groups in each second light mixing unit 2202. The warm light chips 211 and the cold light chips 212 are arranged alternately, so that the second light mixing unit 2202, the multiple cold light chips 212, and the multiple warm light chips 211 constitute a second light mixing sub-module 2012.

[0058] In this embodiment, the outer contours of the first and second photomixing sub-modules 2011, 2012 on the substrate 10 are both circular, and the first and second photomixing sub-modules 2011, 2012 are arranged concentrically. Multiple first and second photomixing sub-modules 2011, 2012 are arranged at intervals, and the first and second photomixing sub-modules 2011, 2012 are arranged in an alternating pattern. A group of cold and warm light mixing units 202 is arranged between the first and second photomixing sub-modules 2011, 2012.

[0059] In this configuration, for each RGB light mixing unit 201, the RGB chipset 22 can mix light not only with the cold and warm chipset 21 in the cold and warm light mixing unit 202 around it, but also with the cold and warm chipset 21, warm light chip 211 or cold light chip 212 on both sides thereof, thereby further enhancing the light mixing effect, improving the lighting performance, and ensuring the user experience.

[0060] 6 to 8 , an embodiment of the present application further provides a light source module 1000 , including the above-mentioned light emitting element 100 . The specific structure of the light emitting element 100 has been described above and will not be repeated here.

[0061] In this embodiment, the light source module 1000 further includes a heat sink 200 and a diffusion lens 300. The substrate 10 of the light emitting element 100 is fixed on the top of the heat sink 200, the diffusion lens 300 is arranged on the side of the substrate 10 away from the heat sink 200, and the chip module 20 is arranged towards the diffusion lens 300.

[0062] The light source module 1000 of this embodiment further includes a support frame 400, which is open at both ends and hollow inside. The support frame 400 has two open ends, a large end 401 and a small end 402. The small end 402 of the support frame 400 is fixed to the surface of the substrate 10, so that the chip module 20 is correspondingly arranged inside the support frame 400. The diffuser lens 300 is fixed to the large end 401 of the support frame 400.

[0063] For the light source module 1000 of this embodiment, the warm light chip 211, the cold light chip 212, the red light chip 221, the green light chip 222 and the blue light chip 223 in the light-emitting element 100 are arranged and packaged on the substrate 10 in a certain manner and arrangement density to form a mixing light unit, so that different light-emitting chips can mix light, thereby eliminating the setting of the mixing light cavity in the light source module 1000, simplifying the structure of the light source module 1000, and being able to reduce light loss, improve light efficiency, and ensure the user experience.

[0064] In addition, the light source module 1000 also includes a cooling fan 500, which is fixed to the side of the radiator 200. The radiator 200 of this embodiment can be composed of a plurality of metal heat sinks, and the plurality of metal heat sinks are arranged in sequence and spaced apart. The cooling fan is fixed to the side of the radiator 200, and the wind generated by the cooling fan 500 can pass through the gaps between the metal heat sinks to improve the overall heat dissipation effect of the light source module 1000. At the same time, due to the light mixing effect of the light-emitting element 100, the light source module 1000 can cancel the setting of the mixing cavity, and then cancel the setting of the heat dissipation structure for dissipating heat from the mixing cavity, so as to further simplify the overall structure of the light source module 1000.

[0065] For the light-emitting element and light source module of this embodiment, the RGB light mixing unit and the cold and warm light mixing unit in the light-emitting element are concentrically arranged, and multiple RGB light mixing units and multiple cold and warm light mixing units are spaced and staggered, and the multiple RGB light mixing units and multiple cold and warm light mixing units are rotationally symmetrical about the center of the chip module. In this way, all RGB chip groups and warm light chips and cold light chips are distributed more evenly on the substrate, so that different light colors can be fully mixed to have a good light mixing effect. Therefore, there is no need to use an additional light mixing cavity structure in the light source module to meet the light mixing effect, thereby simplifying the structure of the light source module, and reducing the light loss caused by multiple reflections in the light mixing cavity, improving the light efficiency, and ensuring the user experience.
