[0029] In order to make the purpose, features and beneficial effects of the present invention more obvious and easy to understand, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] It should be understood that the described embodiments are only some embodiments of the present invention, rather than all embodiments of the present invention. Based on the embodiments of 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.

[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0032] Figure 1 and Figure 2 This is a schematic diagram of the structure of the light source module of an embodiment of the utility model. Please refer to Figure 1 and Figure 2 The light source module 10 includes a light source board 100 , on which an input terminal 110 , an output terminal 120 and a plurality of light emitting units 130 are provided.

[0033] The input end 110 and the output end 120 are both used to connect to other modules in the lamp, for example, can be used to connect to other light source modules.

[0034] The input terminal 110 and the output terminal 120 may be terminals or other electronic components for connection.

[0035] The light emitting unit 130 includes a plurality of lamp beads 131 of different colors.

[0036] In addition, the plurality of light emitting units 130 are sequentially arranged along the regular polygonal arrangement track 101, and each first spacing d (eg Figure 3 The first spacing d refers to the spacing between adjacent lamp beads 131 of the same color along the arrangement track 101.

[0037] Moreover, the input end 110 and the output end 120 are both located between adjacent light emitting units 130 , and the output end 110 and the input end 120 are respectively adjacent to different edges of the light source panel 100 .

[0038] Since the light-emitting units 130 including a plurality of lamp beads 131 of different colors are arranged in sequence along the arrangement trajectory 101 of a regular polygon, and the first spacings d of the plurality of light-emitting units 130 are equal, the spatial distribution differences between the lamp beads 131 of each color are very small. Therefore, especially when the lamp adopts a plurality of the light source modules 10, not only is the surface light distribution consistency of the lamp beads 131 of each color high when they are lit individually, but also the mixed light uniformity is good when the lamp beads 131 of multiple colors are lit.

[0039] On this basis, since the light-emitting units 130 are arranged in sequence along the arrangement track 101 of the regular polygon, a space can be provided between adjacent light-emitting units 130. By utilizing the space, the positions of the input end 110 and the output end 120 are set so that the input end 110 and the output end 120 are both located between adjacent light-emitting units 130, and the output end 110 and the input end 120 are respectively adjacent to different edges of the light source board 100. Therefore, the output end 110 and the input end 120 can be conveniently connected to the other two light source modules 10 without affecting the light-emitting effect of the lamp beads 131 and without structural interference.

[0040] Therefore, the light source module 10 provides uniform surface light distribution and good light mixing effect, while taking into account convenient light source module connection.

[0041] Furthermore, the number of light-emitting units 130 and the number of sides of the regular polygon (i.e., the arrangement trajectory 101) are both 2N, and each light-emitting unit 130 is located at each vertex of the regular polygon. Wherein, N is a natural number greater than or equal to 2. Thus, the spatial distribution difference between the lamp beads 131 of each color is further reduced to provide higher surface light distribution consistency and better light mixing uniformity.

[0042] In this embodiment, the light emitting unit 130 includes four lamp beads 131 of different colors arranged in a 2×2 array. In addition, the plurality of light emitting units 130 are divided into a first light emitting unit group 1301 and a second light emitting unit group 1302 by a designated boundary 102, and the lamp beads 131 of the same color in the first light emitting unit group 1301 and the second light emitting unit group 1302 are arranged upside down in a direction parallel to the designated boundary 102.

[0043] The designated boundary 102 is a symmetry axis of the regular polygon passing through the midpoints of the opposite sides.

[0044] By making the light-emitting unit 130 include four lamp beads 131 of different colors arranged in a 2×2 array, and making the lamp beads 131 of the same color in the first light-emitting unit group 1301 and the second light-emitting unit group 1302 arranged inverted in a direction parallel to the designated boundary 102, the spatial distribution difference between the lamp beads 131 of each color can be further reduced, so as to further provide higher surface light distribution consistency and better light mixing uniformity.

[0045] In addition, by controlling the four colors of lamp beads, not only can the light of different color temperatures and colors emitted by lamps using several of the light source modules 10 be controlled, but the color temperature and color can be changed with high precision and a wide range of changes. Static or dynamic image display effects can also be achieved through program control.

[0046] Specifically, the colors of the lamp beads 131 in the light emitting unit 130 include blue, green, red and yellow. In some other embodiments, they can also be blue, green, orange and white. The color of each lamp bead 131 in the light emitting unit 130 can be configured according to the mixing light requirements.

[0047] Preferably, N=2, the arrangement track 101 is a square, and the lines connecting the lamp beads 131 of the same color in the four light-emitting units 130 form congruent parallelograms (such as Figure 4 As shown). Thus, the spatial distribution differences between the lamp beads 131 of different colors can be minimized to the greatest extent, so as to greatly improve the consistency of surface light distribution and the uniformity of light mixing.

[0048] It should be noted that, for ease of understanding and explanation, Figure 4 The congruent parallelograms formed by the connecting lines between the lamp beads 131 of the same color are represented by dotted lines of similar colors.

[0049] In another embodiment, if Figure 5 As shown, N=3, the arrangement trajectory 201 is a regular hexagon, and the six light-emitting units 230 are respectively located at the vertices of the regular hexagon. In addition, the plurality of light-emitting units 230 are divided into a first light-emitting unit group 2301 and a second light-emitting unit group 2302 by a designated boundary 202, and the lamp beads 231 of the same color in the first light-emitting unit group 2301 and the second light-emitting unit group 2302 are arranged upside down in a direction parallel to the designated boundary 202.

[0050] In yet another embodiment, Figure 6 As shown, N=2, and the arrangement track 301 is a square. The light-emitting unit 330 includes three lamp beads 331 of different colors, and the three lamp beads 331 in the light-emitting unit 330 are arranged in an equilateral triangle, and the four light-emitting units 330 have the same arrangement of lamp beads. Thus, the spatial distribution difference between the lamp beads 331 of each color is further reduced to provide higher surface light distribution consistency and better light mixing uniformity.

[0051] In this embodiment, the light source board 100 is rectangular, and the input end 110 and the output end 120 are respectively adjacent to a set of opposite edges of the light source board 100. Therefore, it is convenient to connect the input end 110 and the output end 120 with other light source modules.

[0052] In this embodiment, a pair of fixing holes 140 are further provided on the light source board 100, and the fixing holes 140 are located between adjacent light emitting units 130, and the pair of fixing holes 140 are respectively adjacent to another set of opposite edges of the light source board 100. Thus, the space between adjacent light emitting units 130 is more fully utilized, and the light source board 100 is fixed without affecting the light emitting effect of the lamp beads 131 and the connection with other light source modules.

[0053] In this embodiment, a lens 150 is also fixed to each lamp bead 131. By providing the lens 150, the light emitted by the lamp bead 131 can be better controlled to optimize the emitted light, further improve the uniformity of the surface light and the light mixing effect, and can also greatly reduce the distance required for light mixing, thereby realizing an ultra-thin lamp structure.

[0054] It should be noted that, for ease of understanding and explanation, Figure 2 The lens 150 is not shown.

[0055] In some other embodiments, the lens may not be provided.

[0056] In this embodiment, a control module is also provided on the light source board 100, and the control module is used to independently control each lamp bead 131. By providing the control module on the light source board 100, the circuit board components of the lamp can be reduced, which is conducive to optimizing the structure of the lamp.

[0057] Preferably, the control module is disposed within the area formed by the arrangement track 101 to more fully utilize the space on the light source panel 100 .

[0058] Correspondingly, the embodiment of the present utility model also provides a light source module, please refer to Figure 7 , Figure 7 The structure diagram of the light source module of one embodiment of the utility model includes more than two Figures 1 to 4 The light source module 10 in the illustrated embodiment, and any two light source modules 10 are connected through the input end 110 of one of the two light source modules 10 and the output end 120 of the other. Thus, the purpose of connecting the light source modules 10 in series or in parallel is achieved. In addition, the light source module also has the effects of the above-mentioned light source module 10, which will not be repeated here.

[0059] It can be understood that, in other embodiments, the light source module may also include the light source module in another embodiment, still another embodiment or some other embodiments mentioned above.

[0060] Accordingly, an embodiment of the present utility model further provides a lamp, such as Figure 8 As shown, Figure 81 is a schematic diagram of the structure of a lamp according to an embodiment of the utility model. The lamp comprises: the light source module as described above and a housing 20 , and the light source module is fixed on the housing 20 .
