Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, specifically relating to a light source module and a lighting device. Background Technology

[0002] Currently, during the filming of movies, stage performances, studios, and sporting events, it is often necessary to provide supplemental lighting for the subject or environment. To obtain white light or meet other lighting requirements, light-emitting components of different colors need to be integrated onto the same substrate to mix the different colors of light emitted by the components. For example, multiple light-emitting components of different colors can be arranged on the same substrate. These components can include one or more of red, green, and blue LEDs. For instance, a light-emitting component containing only a single red LED emits red light, a light-emitting component containing only a single green LED emits green light, and a light-emitting component containing only a single blue LED emits blue light. The light-emitting components of different colors are arranged according to a certain pattern or order to achieve light mixing.

[0003] In related technologies, when multiple light-emitting components with different colors are arranged on a substrate, uneven mixing can easily lead to noticeable blocky color bands, such as localized reddish, greenish, or bluish color bands, which significantly affect the visual effect. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a light source module in which the light-emitting unit formed by X light-emitting elements is more uniformly mixed with light, and thus the light mixing of the light source module is more uniform, so that the light source module will not have obvious blocky color bands and the visual effect is better.

[0005] The second objective of this utility model is to provide a lighting device that uses the above-mentioned light source module, which has a more uniform light mixing, does not produce obvious blocky color bands, and has a better visual effect.

[0006] One of the objectives of this utility model is achieved through the following technical solution:

[0007] A light source module, comprising:

[0021] As an optional implementation, the color-mixing light-emitting element includes Z first chips with different emitting colors, which are uniformly arranged around the geometric center point of the color-mixing light-emitting element.

[0022] As an optional implementation, in the light source module, in the same row of two adjacent light-emitting units in the second direction, the first color-mixing light-emitting element is rotated by β degrees around its geometric center point and then has the same setting direction as the second color-mixing light-emitting element.

[0023] In the same light-emitting unit, after the previous color-mixing light-emitting element in two adjacent rows in the first direction is rotated by β degrees around its geometric center point, it is set in the same direction as the next color-mixing light-emitting element.

[0024] Where β = 360° / Z.

[0049] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0050] Example 1

[0051] See Figures 1 to 7This utility model discloses a light source module, including: a substrate 10; a light-emitting unit 20 disposed on the substrate 10; the light-emitting unit 20 includes X light-emitting elements 201, the X light-emitting elements 201 are arranged in M ​​rows along a first direction and in N columns along a second direction, where M=aN, X=MN, a≥2, N≥3, and M, a, and N are all natural numbers; the light emission color of the light-emitting elements 201 is one of N light emission colors, and the number of light-emitting elements 201 of each light emission color is M; in the light-emitting unit 20, the light emission colors of the N light-emitting elements 201 in the same row are all different; the light emission colors of two adjacent light-emitting elements 201 in the same column are different, and the light emission color of the second light-emitting element 201 in the M light-emitting elements 201 in the same column is different from the light emission color of the (N+2)th light-emitting element 201.

[0052] The light-emitting unit 20 formed by the arrangement of X light-emitting elements 201 of this invention has a more uniform light mixing, and thus the light mixing of the light source module is more uniform. Therefore, the light source module will not have obvious blocky color bands, and the visual effect is better.

[0053] See Figure 1 as well as Figure 2 The first direction and the second direction are perpendicular to each other. For example, the first direction is the Y-axis direction of the coordinate system and the second direction is the X-axis direction of the coordinate system, so the light-emitting unit 20 is an array structure arranged horizontally and vertically.

[0054] In this embodiment of the invention, a = 2, N = 3, M = 6, and X = 18.

[0055] It should be noted that when N=3, the light-emitting unit 20 is an array structure of 6 rows and 3 columns, and the light-emitting unit 20 has a total of 18 light-emitting elements 201; since the light-emitting element 201 emits one of three light-emitting colors, the number of light-emitting elements 201 of the three different light-emitting colors is equal, the ratio of the number of light-emitting elements 201 of the three light-emitting colors is 1:1:1, and the number of light-emitting elements 201 of each light-emitting color is 6.

[0056] In this light-emitting unit 20, the three light-emitting elements 201 in the same row all emit different colors; the two adjacent light-emitting elements 201 in the same column emit different colors, and the second light-emitting element 201 in the same column emits a different color than the fifth light-emitting element 201, thus achieving the following effect: Figure 1 The light-emitting unit 20 shown is formed by 18 light-emitting elements 201 arranged in a way that results in relatively uniform light mixing. This light-emitting unit 20 is the smallest unit of the light source module.

[0057] In this embodiment of the invention, the light source module includes Y light-emitting units 20, which are arranged in rows M' along a first direction and columns N' along a second direction, where Y = M'N', Y≥1, M'≥1, N'≥1, and Y, M', and N' are all natural numbers. In the light source module, the light emission colors of two adjacent light-emitting units 201 in the same row are different, and the light emission colors of two adjacent light-emitting units 201 in the same column are different.

[0058] It should be noted that the light source module may include only one light-emitting unit 20, or it may include two or more light-emitting units 20. The values ​​of M' and N' can be selected and matched according to the actual application scenario and application environment, and are not limited.

[0059] For example, see Figure 2 With M'=2, N'=3, and Y=6, the light source module has a 2-row, 3-column array structure and a total of 6 light-emitting units 20. In this light source module, the light emission colors of two adjacent light-emitting units 201 in the same row are different, and the light emission colors of two adjacent light-emitting units 201 in the same column are different, which makes the light mixing of the light source module more uniform. As a result, the light source module does not have obvious blocky color bands, and the visual effect is better.

[0060] In this embodiment of the present invention, in the light source module, the distance between two adjacent light-emitting elements 201 in the same row is L1, and the distance between two adjacent light-emitting elements 201 in the same column is L2; ​​L1=L2.

[0061] Since the spacing between any two adjacent light-emitting elements 201 located in the same row and column is equal in this light source module, it can be seen that the spacing between any two adjacent light-emitting elements 201 located in the same row and column is also equal in the light-emitting unit 20. This achieves uniform arrangement of the light-emitting elements 201, avoids the situation where the light-emitting elements 201 are arranged too densely or too sparsely in some areas, and thus obtains a light-emitting module with more uniform light mixing.

[0062] In this embodiment of the utility model, the light-emitting element 201 includes a color-mixing light-emitting element 2011 or a single-color light-emitting element 2012; the color-mixing light-emitting element 2011 includes Z first chips 20111, Z≥2, Z is a natural number, and at least two first chips 20111 in the same color-mixing light-emitting element 2011 emit different colors; the single-color light-emitting element 2012 includes Z' second chips 20121 with the same emission color, Z'≥1, and Z' is a natural number.

[0063] When the light-emitting element 201 in a light-emitting unit 20 includes a monochrome light-emitting element 2012, the monochrome light-emitting element 2012 can be a red light-emitting element, a green light-emitting element, or a blue light-emitting element, etc.; for example, some light-emitting elements 201 in a light-emitting unit 20 include red light-emitting elements, some light-emitting elements 201 in a light-emitting unit 20 include green light-emitting elements, and the remaining light-emitting elements 201 in a light-emitting unit 20 include blue light-emitting elements, and in this light-emitting unit 20, the ratio of the number of red light-emitting elements, green light-emitting elements, and blue light-emitting elements is 1:1:1.

[0064] When a portion of the light-emitting elements 201 in a light-emitting unit 20 includes a monochromatic light-emitting element 2012 and the remaining portion includes a multi-color light-emitting element 2011, for example, the monochromatic light-emitting element 2012 can be a red light-emitting element or a green light-emitting element, etc., and the multi-color light-emitting element 2011 can be a red-green-blue light-emitting element, etc.; for example, see [reference needed]. Figures 1 to 7 A portion of the light-emitting elements 201 in a light-emitting unit 20 includes a red light-emitting element, a portion of the light-emitting elements 201 in a light-emitting unit 20 includes a green light-emitting element, and the remaining portion of the light-emitting elements 201 in a light-emitting unit 20 includes red, green, and blue light-emitting elements. In this light-emitting unit 20, the ratio of the number of red light-emitting elements, green light-emitting elements, and red, green, and blue light-emitting elements is 1:1:1. The red, green, and blue light-emitting elements include three first chips 20111 with different emitting colors to achieve light mixing. The three first chips 20111 with different emitting colors are a first red chip, a first green chip, and a first blue chip, respectively. Both the red light-emitting element and the green light-emitting element include one second chip 20121. The second chip 20121 in the red light-emitting element is a second red chip, and the second chip 20121 in the green light-emitting element 201 is a second green chip.

[0065] For example, when all the light-emitting elements 201 in a light-emitting unit 20 include a color-mixing light-emitting element 2011, such as a red-green light-emitting element, a red-blue light-emitting element, or a red-green-blue light-emitting element; for example, some of the light-emitting elements 201 in a light-emitting unit 20 include red-green light-emitting elements, some of the light-emitting elements 201 in a light-emitting unit 20 include red-blue light-emitting elements, and the remaining light-emitting elements 201 in a light-emitting unit 20 include red-green-blue light-emitting elements, and in this light-emitting unit 20, the ratio of the number of red-green light-emitting elements, red-blue light-emitting elements, and red-green-blue light-emitting elements is 1:1:1.

[0066] As can be seen, the specific type and quantity of the light-emitting element 201 can be selected and matched according to the actual application scenario and application environment, without limitation, and will not be listed one by one.

[0067] The following provides further explanation of the mixed-color luminous element 2011.

[0068] In this embodiment of the present invention, the color-mixing light-emitting element 2011 includes Z first chips 20111 with different emitting colors, and the Z first chips 20111 with different emitting colors are uniformly arranged around the geometric center point of the color-mixing light-emitting element 2011.

[0069] See Figures 1 to 7 The color-mixing light-emitting element 2011 includes three first chips 20111 with different light-emitting colors. The three first chips 20111 with different light-emitting colors are evenly arranged around the geometric center point of the color-mixing light-emitting element 2011. For example, the three first chips 20111 with different light-emitting colors are a first red chip, a first green chip, and a first blue chip, and the line connecting the first red chip, the first green chip, and the first blue chip is an equilateral triangle.

[0070] In this embodiment of the present invention, in the light source module, in the same row of two adjacent light-emitting units 20 in the second direction, the previous color-mixing light-emitting element 2011 is rotated by β degrees around its geometric center point and then has the same setting direction as the next color-mixing light-emitting element 2011; in the same light-emitting unit 20, the previous color-mixing light-emitting element 2011 in two adjacent rows in the first direction is rotated by β degrees around its geometric center point and then has the same setting direction as the next color-mixing light-emitting element 2011; wherein, β = 360° / Z.

[0071] Continue reading Figures 3 to 5 When Z=3, β=120°. By changing the setting direction of the color mixing light source 2011, the light emission direction of the first chip 20111 with different light emission colors in the color mixing light source 2011 is changed, thereby making the light mixing of the light source module more uniform.

[0072] In this embodiment of the present invention, in the light source module, in the same row of two adjacent light-emitting units 20 in the second direction, the first color-mixing light-emitting element 2011 is rotated counterclockwise by β degrees around its geometric center point and then has the same setting direction as the second color-mixing light-emitting element 2011.

[0073] See Figures 1 to 2 When Z=3, β=120°, the second direction is the X-axis direction of the coordinate system, and the X-axis direction of the coordinate system is used as the initial reference direction.

[0074] The previous color-mixing light-emitting element 2011 is rotated counterclockwise by β degrees around its geometric center point and is set in the same direction as the next color-mixing light-emitting element 2011. This means that when installing the next color-mixing light-emitting element 2011, it is first placed according to the setting direction of the previous color-mixing light-emitting element 2011, and then rotated counterclockwise to β angle before installation.

[0075] In other embodiments, in the light source module, in the same row of two adjacent light-emitting units 20 in the second direction, the first color-mixing light-emitting element 2011 is rotated clockwise by β degrees around its geometric center point and then has the same orientation as the second color-mixing light-emitting element 2011.

[0076] In this embodiment of the present invention, in the same light-emitting unit 20, after the previous color-mixing light-emitting element 2011 in two adjacent rows in the first direction is rotated counterclockwise by β degrees around its geometric center point, it is set in the same direction as the next color-mixing light-emitting element 2011.

[0077] See Figures 1 to 2 When Z=3, β=120°, the first direction is the Y-axis direction of the coordinate system, and the Y-axis direction of the coordinate system is used as the initial reference direction.

[0078] The previous color-mixing light-emitting element 2011 is rotated counterclockwise by β degrees around its geometric center point and is set in the same direction as the next color-mixing light-emitting element 2011. This means that when the next color-mixing light-emitting element 2011 is installed, it is first placed according to the setting direction of the previous color-mixing light-emitting element 2011, and then rotated counterclockwise to β angle before installation.

[0079] In other embodiments, in the same light-emitting unit 20, after the previous color-mixing light-emitting element 2011 in two adjacent rows in the first direction is rotated clockwise by β degrees around its geometric center point, it is in the same setting direction as the next color-mixing light-emitting element 2011.
