[0030] 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 invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Example 1 Please see Figure 1 and Figure 2 This embodiment provides a light source module 100, including a substrate 1 and a light mixing unit 2. The substrate has a base surface 10, and the light mixing unit 2 is attached and fixed to the base surface 10. The light mixing unit 2 includes a first light-emitting chip 21, a second light-emitting chip 22, and a third light-emitting chip 23.

[0032] The first light-emitting chip 21 emits a first light color, which is red and white light; the second light-emitting chip 22 emits a second light color, which is sky blue light; and the third light-emitting chip 23 emits a third light color, which is pale green light. The first light-emitting chip 21, the second light-emitting chip 22, and the third light-emitting chip 23 constitute a light mixing unit with a new three-primary-color light source.

[0033] Specifically, in this embodiment, the first light-emitting chip 21 emits red and white light with a peak wavelength in the range of 625nm-645nm. A red phosphor is coated on the surface of the first light-emitting chip 21. The second light-emitting chip 22 emits sky blue light with a peak wavelength in the range of 480nm-495nm. A cyan phosphor is coated on the surface of the second light-emitting chip 22. The third light-emitting chip 23 emits light green light with a peak wavelength in the range of 530nm-550nm. A yellow phosphor is coated on the surface of the third light-emitting chip 23.

[0034] More specifically, in the CIE-1931 color space, red and white light are located within the quadrilateral region enclosed by (0.665, 0.308), (0.681, 0.318), (0.578, 0.415), and (0.558, 0.386).

[0035] The sky-blue light is located within the quadrilateral area enclosed by (0.372, 0.57), (0.42, 0.54), (0.375, 0.45), and (0.33, 0.455).

[0036] The light green light is located within the quadrilateral region enclosed by (0.15, 0.115), (0.165, 0.125), (0.177, 0.212), and (0.15, 0.2).

[0037] The base surface 10 has a horizontal axis X and a vertical axis Y, which are perpendicular to each other. In some embodiments, a first light-emitting chip 21, a second light-emitting chip 22, and a third light-emitting chip 23 are disposed on the base surface 10 along a first direction L1, which is parallel to the horizontal axis X. In some embodiments, the first light-emitting chip 21, the second light-emitting chip 22, and the third light-emitting chip 23 are disposed on the base surface 10 along a second direction L2, which is parallel to the vertical axis Y.

[0038] In terms of arrangement, the first light-emitting chip 21, the second light-emitting chip 22 and the third light-emitting chip 23 are arranged closely together, or gaps that do not affect the light emission effect can be set between adjacent light-emitting chips.

[0039] The three colors of light emitted by the first light-emitting chip 21, the second light-emitting chip 22, and the third light-emitting chip are mixed and emitted to the outside, forming three primary color pixels by the light mixing unit 2. Furthermore, multiple light mixing units 2 are arranged in an array on the base surface 10, thereby effectively increasing the number of imaging points on the small base surface 10, which is beneficial for the miniaturization and shape diversification of the light source module.

[0040] Further reference Figure 2 In this embodiment, the first light-emitting chip 21, the second light-emitting chip 22, and the third light-emitting chip 23 are disposed on the base surface 10 along the first direction L1. The second light-emitting chip 22 and the third light-emitting chip 23 are integrated into a single dual-color chip unit 30. The third light-emitting chip 23 is adjacent to the first light-emitting chip 21, and the second light-emitting chip 22 is farther away from the first light-emitting chip 21 than the third light-emitting chip 23. The distance between the first light-emitting chip 21 and the single dual-color chip unit 30 is a first distance a, and the distance between the second light-emitting chip 22 and the third light-emitting chip 23 is a second distance b. The first distance a and the second distance b have the relationship: a ≥ b.

[0041] In the dual-color chip unit 30, the second light-emitting chip 22 and the third light-emitting chip 23 are closely arranged, with a second distance b between them. This second distance b is the gap between the second light-emitting chip 22 and the third light-emitting chip 23, and this gap can be made very small. In some embodiments, the first light-emitting chip 21 is arranged adjacent to the dual-color chip unit 30, that is, the first distance a between the first light-emitting chip 21 and the dual-color chip unit 30 can also be made very small. Considering the actual packaging situation, the first distance a is greater than or equal to the second distance b.

[0042] In this embodiment, the first distance a is greater than the second distance b. In the light mixing unit 2, the second and third light colors emitted by the second light-emitting chip 22 and the third light-emitting chip 23 in the dual-color chip unit 30 are first mixed together, and then mixed with the first light color emitted by the first light-emitting chip 21 to form three primary color pixels. This effectively increases the number of imaging points on a small base surface, which is beneficial for the miniaturization and shape diversification of the light source module. Furthermore, by integrating the chips and optimizing the distance between the chips, the uniformity of light output and color consistency are improved.

[0043] It should be noted that the light source module 100 in this embodiment also includes a dimming IC3 and wires 4. The dimming IC3, or dimming integrated circuit, is an electronic component designed to control brightness changes. The dimming IC3 adjusts the luminous flux and output ratio of the first, second, and third colors of the light mixing unit 20. In terms of pixel control, the dimming IC receives control signals and drives the light mixing unit 20, which forms the three primary color pixels, to emit light or change color.

[0044] One end of the wire 4 is connected to the substrate, and the other end is connected to an adjacent light source module or an external power supply. Wire 4 is used to power the dimming IC 3 and the mixing unit 20, and also for circuit connection and signal transmission between adjacent light source modules. Specifically, one end of the wire 4 is soldered to a corresponding pad on the substrate, and the other end has a terminal block. Each light source module has two wires, one with a female connector terminal block 41 and the other with a male connector terminal block 42. This allows adjacent light source modules to be connected together via wires, facilitating installation and assembly.

[0045] The light source module provided in this embodiment uses a first light-emitting chip, a second light-emitting chip, and a third light-emitting chip that emit different colors of light, arranged on a base surface in a first or second direction to form a light mixing unit with three primary color pixels. This effectively increases the number of imaging points on a small base surface, which is beneficial for the miniaturization and shape diversification of the light source module. Furthermore, by integrating the chips and optimizing the distance between them, the uniformity of light emission and color consistency are improved, and the light emission effect can be switched according to the specific lighting scene.

In this embodiment, the mixing unit 2 includes a first light-emitting chip 21, a second light-emitting chip 22, and a third light-emitting chip 23. The first, second, and third light-emitting chips are fixed to the base surface using SMD packaging, and the corresponding brackets can be made of PPA, PCT, or EMC materials.

[0047] The first light-emitting chip 21 emits red and white light with a peak wavelength in the range of 625nm-645nm. The second light-emitting chip 22 emits sky blue light with a peak wavelength in the range of 480nm-495nm. The third light-emitting chip 23 emits light green light with a peak wavelength in the range of 530nm-550nm. The surfaces of the first light-emitting chip 21, the second light-emitting chip 22, and the third light-emitting chip 23 are respectively covered with red phosphor, cyan phosphor, and yellow phosphor.

[0048] When the first light-emitting chip 21, the second light-emitting chip 22, and the third light-emitting chip 23 are disposed on the base surface along the first direction L1, the second light-emitting chip 22 is disposed between the first light-emitting chip 21 and the third light-emitting chip 23, and the distance between adjacent light-emitting chips is the same.

[0049] like Figure 3 As shown, the distance between the first light-emitting chip 21 and the second light-emitting chip 22 is a1, and the distance between the second light-emitting chip 22 and the third light-emitting chip 23 is a2, where a1 = a2.

These colors are mixed together to form three primary color pixels, thereby effectively increasing the number of imaging points on a small surface area. This is beneficial for the miniaturization and shape diversification of the light source module. Furthermore, by optimizing the distance between the chips, the uniformity of light output and color consistency are improved.

[0052] When the first light-emitting chip 21, the second light-emitting chip 22, and the third light-emitting chip 23 are disposed on the base surface along the first direction L1, the second light-emitting chip 22 is disposed between the first light-emitting chip 21 and the third light-emitting chip 23, and the distance between adjacent light-emitting chips is the same.

[0053] like Figure 4 As shown, the distance between the first light-emitting chip 21 and the second light-emitting chip 22 is a3, and the distance between the second light-emitting chip 22 and the third light-emitting chip 23 is a4, where a3 = a4. For other structures in this embodiment, please refer to the relevant description in Embodiment 1, which will not be repeated here.
