The light source module 10 and the lamp in the embodiment of the present invention will now be described.

Referring to fig. 1, the light source module 10 includes a substrate 100, a first light source unit 200, a second light source unit 300, and a third light source unit 400.

Referring to fig. 2, a surface of the substrate 100 has two or more annular directions 101, and the two or more annular directions 101 are nested with each other. In other words, the annular directions 101 can surround a certain central point for a circle, instead of a straight line or a curve, the annular directions 101 do not intersect with each other, and are not separated from each other, and the annular direction 101 with a small area is located in the middle of the other annular directions 101. Specifically, the shape of the annular direction 101 may be circular, elliptical, polygonal, or irregular. The shape of any two annular directions 101 may be the same or different. The number of annular directions 101 varies from 2 to 10. In the embodiment shown in the figures, the annular directions 101 are all circular, and the circles are concentric circles, that is, two or more annular directions 101 are arranged in concentric circles.

Referring to fig. 1, the first light source unit 200 includes a plurality of first monochromatic light emitting members 210 installed at intervals in the ring direction 101, and the plurality of first monochromatic light emitting members 210 are connected in series. The second light source unit 300 includes a plurality of second mono light emitting members 310 installed at intervals in the ring direction 101, and the plurality of second mono light emitting members 310 are connected in series. The third light source unit 400 includes a plurality of third mono light emitting members 410 installed at intervals in the ring direction 101, and the plurality of third mono light emitting members 410 are connected in series.

Wherein the first, second and third mono light emitting members 210, 310 and 410 emit light of different colors. Thus, the first monochromatic light emitting element 210, the second monochromatic light emitting element 310 and the third monochromatic light emitting element 410 are independently conducted, and the emitted light colors are different from each other, and can be arbitrarily combined and mixed to form different colored light, thereby satisfying the color dimming function.

Specifically, the first, second and third mono light emitters 210, 310 and 410 emit light of different wavelengths, thereby forming light of different colors. In some embodiments, the first and second monochromatic light emitting members 210, 310 and 410 are blue, red and green, respectively, and thus the first, second and third monochromatic light emitting members 210, 310 and 410 can be combined to form any one color. In some embodiments, the first luminescent member 210 is a cyan luminescent member, the second luminescent member 310 is a magenta luminescent member, and the third luminescent member 410 is a yellow luminescent member, which can be combined to form any one color.

The first, second and third mono-color light emitting members 210, 310 and 410 are spaced apart from each other in the annular direction 101, so that when the first mono-color light emitting member 210 emits light independently, the luminance of the mono-color light emitted from the first mono-color light emitting member 210 on the substrate 100 is uniform. Similarly, when the second mono-color light emitting member 310 emits light alone, the brightness of the mono-color light emitted from the second mono-color light emitting member 310 on the substrate 100 is uniform. The definition light emitting member includes a first monochromatic light emitting member 210, a second monochromatic light emitting member 310 and a third monochromatic light emitting member 410, because the first monochromatic light emitting member 210, the second monochromatic light emitting member 310 and the third monochromatic light emitting member 410 are combined to emit light, because each monochromatic light is uniformly distributed, the mixing degree of the mixed light is also uniform, and the adjacent three light emitting members positioned in the same annular direction 101 are the first monochromatic light emitting member 210, the second monochromatic light emitting member 310 and the third monochromatic light emitting member 410, that is, the first monochromatic light emitting member 210, the second monochromatic light emitting member 310 and the third monochromatic light emitting member 410 are adjacently arranged in each annular direction 101, so that the mixed light is uniform, and the improvement of the mixing uniformity degree of the light source module 10 is facilitated.

Specifically, the light emitting member is an LED chip. The LED chip is attached to the substrate 100 with a conductive or non-conductive adhesive and then wire-bonded to achieve electrical connection thereof. Therefore, the LED chip is directly packaged on the substrate 100, and has the advantages of short heat conduction path, good heat dissipation, low cost, good light spot and the like, and the production process is mature and the yield is high. The first, second and third mono light emitters 210, 310 and 410 are substantially the same size. The maximum driving current of the light emitting element is 1A-2A to improve the light emitting efficiency, so that the light source module 10 provides sufficient luminous flux.

In one embodiment, referring to fig. 1 and 2, the surface of the substrate 100 has a first circuit for connecting a plurality of first monochromic light emitting members 210 in series, so that the first monochromic light emitting members 210 are directly mounted on the surface of the substrate 100, i.e., connected in series. The substrate 100 further has a first positive access port 102 and a first negative access port 103 electrically connected to two ends of the first line, respectively, so as to be electrically connected to an external power source, and further supply power to the first monochromatic light emitting element 210. Specifically, the first positive access port 102 and the first negative access port 103 are both pads, and the first positive access port 102 and the first negative access port 103 are located on two opposite sides of the substrate 100 so as to have enough space for wiring. Wherein the first positive access port 102 and the first negative access port 103 can be both located on one surface of the substrate 100 having the first monochromatic light emitting member 210, so as to print the first line, the first positive access port 102 and the first negative access port 103 on the same surface of the substrate 100. It will be appreciated that in other embodiments at least one of first positive access port 102 and first negative access port 103 may be located on a surface of substrate 100 remote from first monochromatic light emitter 210.

In one embodiment, referring to fig. 1 and 2, the surface of the substrate 100 has a second line for connecting a plurality of second single color light emitting members 310 in series, and the substrate 100 further has a second positive access port 104 and a second negative access port 105 electrically connected to both ends of the second line, respectively. Specifically, the second positive access port 104 and the second negative access port 105 are both bonding pads, and the second positive access port 104 and the second negative access port 105 are located on two opposite sides of the substrate 100. The second positive access ports 104 and the second negative access ports 105 may both be located on a surface of the substrate 100 having the second mono-color light emitting member 310, or at least one of the second positive access ports 104 and the second negative access ports 105 may be located on a surface of the substrate 100 remote from the second mono-color light emitting member 310.

In one embodiment, referring to fig. 1 and 2, the surface of the substrate 100 has a third line for connecting a plurality of third single-color light emitting members 410 in series, and the substrate 100 further has a third positive access port 106 and a third negative access port 107 electrically connected to both ends of the third line, respectively. Specifically, the third positive access port 106 and the third negative access port 107 are both pads, and the third positive access port 106 and the third negative access port 107 are located on two opposite sides of the substrate 100. The third positive access ports 106 and the third negative access ports 107 may both be located on a surface of the substrate 100 having the third mono-color light emitting member 410, or at least one of the third positive access ports 106 and the third negative access ports 107 may be located on a surface of the substrate 100 remote from the third mono-color light emitting member 410.

As shown in fig. 2, the first positive access port 102, the second positive access port 104 and the third positive access port 106 are located on the same side of the substrate 100 and are spaced apart from each other to facilitate electrical connection with an external positive electrode. The first negative access port 103, the second negative access port 105 and the third negative access port 107 are located on the other side of the substrate 100 and are distributed at intervals, so as to be electrically connected with an external negative electrode.

To facilitate viewing of the distribution structure of the first mono-color light emitting members 210, fig. 3 illustrates the annular direction 101 of the substrate 100. As shown in fig. 3, the plurality of first mono-color light emitting members 210 are uniformly distributed in the same annular direction 101, so that the light distribution of the first mono-color light emitting members 210 in each annular direction 101 is uniform. When the first mono light emitting member 210 emits light alone, uniform mono light can be provided; when the first single color light emitting member 210 emits light in combination with other light emitting members, uniform single color light can be provided to be uniformly mixed with light of the other light emitting members.

As shown in fig. 3, the plurality of annular directions 101 are arranged in concentric circles. Any two first monochromatic light emitting members 210 are located in different radial directions of the concentric circles to prevent the light emitted from the first monochromatic light emitting members 210 in a certain radial direction from being concentrated, which is beneficial for the first monochromatic light emitting members 210 to provide uniform monochromatic light.

As shown in FIG. 3, the ring directions 101 are 4, and the number of the first monochromatic light emitting members 210 from the inside to the outside in different ring directions 101 is 2, 6, 8 and 8, respectively. The first mono light emitters 210 in each annular direction 101 are uniformly distributed.

In order to facilitate the observation of the distribution structure of the second mono light emitter 310, fig. 4 illustrates the circular direction 101 of the substrate 100. As shown in fig. 4, the plurality of second mono-color light emitting members 310 are uniformly distributed in the same annular direction 101, so that the light distribution of the second mono-color light emitting members 310 is uniform in each annular direction 101. When the second mono light emitting member 310 emits light alone, uniform mono light can be provided; when the second mono light emitting member 310 emits light in combination with other light emitting members, uniform mono light can be provided to be uniformly mixed with light of other light emitting members.

As shown in fig. 4, the plurality of annular directions 101 are arranged in concentric circles, and any two second monochromatic light emitting members 310 are located in different radial directions of the concentric circles, so that the light emitted from the second monochromatic light emitting members 310 in a certain radial direction is prevented from being concentrated, and the second monochromatic light emitting members 310 can provide uniform monochromatic light.

As shown in FIG. 4, the annular directions 101 are 4, and the number of the second monochromatic light-emitting members 310 from the inside to the outside in the different annular directions 101 is 2, 6, 8 and 8, respectively. The second mono light emitters 310 are uniformly distributed in each annular direction 101.

In order to facilitate the observation of the distribution structure of the third mono light emitting member 410, fig. 5 illustrates the circular direction 101 of the substrate 100. As shown in FIG. 5, the plurality of third mono-color light emitting members 410 are uniformly distributed in the same annular direction 101, so that the light distribution of the third mono-color light emitting members 410 is uniform in each annular direction 101. When the third mono light emitting member 410 emits light alone, uniform mono light can be provided; when the third monochrome light emitting element 410 emits light in combination with other light emitting elements, uniform monochrome light can be provided to be uniformly mixed with light of other light emitting elements.

As shown in fig. 5, the plurality of annular directions 101 are arranged in concentric circles, and any two third monochromatic light emitting devices 410 are located in different radial directions of the concentric circles, so as to avoid relatively concentrated light emitted from the third monochromatic light emitting devices 410 in a certain radial direction, which is beneficial for the third monochromatic light emitting devices 410 to provide uniform monochromatic light.

As shown in FIG. 5, the circular directions 101 are 4, and the number of the third mono-color light emitting members 410 from the inside to the outside in the different circular directions 101 is 2, 6, 8 and 8, respectively. The third mono-color light emitting members 410 are uniformly distributed in each of the ring directions 101.

In some embodiments, in conjunction with FIG. 1, the number of first, second and third monochromating light emitting members 210, 310 and 410 is the same. Moreover, the number of the first, second and third mono-color light emitting members 210, 310 and 410 in each annular direction 101 is the same, so that the light mixing of the first, second and third mono-color light emitting members 210, 310 and 410 in any one annular direction 101 is uniform. For example, when the first and second monochromic light emitting members 210 and 310 are combined to mix light, the third monochromic light emitting member 410 is not lit, and since the first and second monochromic light emitting members 210 and 310 are the same in number in each annular direction 101 and are adjacently disposed, the light emitted from the first and second monochromic light emitting members 210 and 310 can be uniformly mixed, thereby preventing the light emitted from the first or second monochromic light emitting members 210 and 310 from being concentrated at a certain position in the annular direction 101 and from being sparse at other positions.

In the embodiment of fig. 1, the plurality of luminous elements are evenly distributed in any one of the annular directions 101. The first, second and third mono light emitting members 210, 310 and 410 are sequentially staggered to realize uniform light mixing as much as possible. One second and one third mono-color light emitting member 310 and 410 are provided in every two adjacent first mono-color light emitting members 210, one first and one third mono-color light emitting member 210 and 410 are provided in every two adjacent second mono-color light emitting members 310, and one first and one second mono-color light emitting member 210 and one third mono-color light emitting member 310 are provided in every two adjacent third mono-color light emitting members 410.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of the present invention.
