Description

Technical Field

[0001] The present invention belongs to the technical field of lamps, and in particular relates to an illuminating lamp, a lighting device, a light source assembly and a direct-down type light-emitting lighting device. Background Art

[0002] In order for lighting equipment to have the functions of both white light lighting and colored light lighting, single white light lamp beads and RGB lamp beads need to be mixed and arranged on the light board.

[0003] In the prior art, there are two arrangements of lamp beads in lighting equipment: direct-down and side-emitting. The side-emitting method is to install the lamp beads on the peripheral side of the inner wall of the lighting equipment and emit them from the lampshade after optical reflection and / or refraction; while the direct-down method is to install the lamp beads at the bottom of the lighting equipment, with the optical axis perpendicular to the lampshade.

[0004] However, the side-lighting arrangement in the prior art cannot achieve precise control of the lighting zoning, and there will be some inconsistencies in the colors and edges of the middle area of ​​the side-lighting; and the direct-down arrangement can only ensure that one of the single white light or RGB lamp beads has a good uniformity on the lampshade, and cannot ensure that the effects of both are balanced; the inventors found that the reason for the above-mentioned technical defects is that when there are two or more lamp beads at the same time, the uniform arrangement of the lamp beads on the lamp board will inevitably cause one lamp bead to be offset to one side compared with the arrangement of another lamp bead on the lamp board as a whole, thereby causing the light output of one lamp bead on the lamp board to be offset to one side compared with the other lamp bead as a whole, which in turn causes a dark area to appear on one side of the lamp board, and the light output effect is poor.

[0073] Reference Manual Attached Figure 1The present application provides a lighting lamp, which includes a lamp board 400, a plurality of first lamp beads 100 and a plurality of second lamp beads 200; wherein, the plurality of first lamp beads 100 are arranged on the lamp board 400, and two adjacent first lamp beads 100 are arranged equidistantly or substantially equidistantly based on a first row spacing, and the plurality of second lamp beads 200 are arranged on the lamp board 400, and two adjacent second lamp beads 200 are arranged equidistantly or substantially equidistantly based on a second row spacing, and an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, and the angle between the geometric center of the first lamp bead 100 close to the coordinate origin and the X-axis or the Y-axis is an acute angle, the first lamp bead 100 and the second lamp bead 200 are lamp beads with different parameters, and / or the switching states of the first lamp bead 100 and the second lamp bead 200 are mutually exclusive.

[0074] In some embodiments, a plurality of first lamp beads 100 are disposed on a lamp board 400, two adjacent first lamp beads 100 are arranged equidistantly based on a first row spacing, and two adjacent first lamp beads 100 are arranged equidistantly based on a first column spacing; a plurality of second lamp beads 200 are disposed on a lamp board 400, two adjacent second lamp beads 200 are arranged equidistantly based on a second row spacing, and two adjacent second lamp beads 200 are arranged equidistantly based on a second column spacing, an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, and an angle between the geometric center of the first lamp bead 100 close to the coordinate origin and the X-axis or the Y-axis is an acute angle; the first lamp bead 100 and the second lamp bead 200 are lamp beads with different parameters, and / or when the lighting lamp is working, the switch states of the first lamp bead 100 and the second lamp bead 200 are mutually exclusive and are not lit at the same time, when the first lamp bead 100 is in the lighting state, the second lamp bead 200 is off, and when the second lamp bead 200 is in the lighting state, the first lamp bead 100 is off. The first lamp bead 100 and the second lamp bead 200 can be controlled independently, and their switching, brightness, color temperature or color adjustment can be controlled by a microprocessor respectively.

[0075] It should be noted that the parameter characteristics of the first lamp bead 100 and the second lamp bead 200 are different. The difference lies in that the two lamp beads have different spectral characteristics, different light color characteristics, different emission angles or different packaging forms. The spectral characteristics include spectral distribution, color temperature and color rendering index and other characteristics; in some embodiments, the first lamp bead 100 is a white light lamp bead, and the second lamp bead 200 is a colored light lamp bead (such as RGB lamp bead, RGBW lamp bead, RGBCW lamp bead, RGBWW lamp bead); in some embodiments, the first lamp bead 100 is a cold light white light lamp bead, and the second lamp bead 200 is a warm light white light lamp bead; in some embodiments, the first lamp bead 100 is a LED lamp bead that can be adapted to TV lens, and the second lamp bead 200 is another different type of LED lamp bead that can be adapted to TV lens; in some embodiments, the first lamp bead 100 is a COB lamp bead, and the second lamp bead is an SMD lamp bead.

[0076] In addition, when the first lamp beads 100 or the second lamp beads 200 are arranged along the length direction of the lamp board 400, the spacing between two adjacent first lamp beads 100 is the first row spacing, and the spacing between two adjacent second lamp beads 200 is the second row spacing; and when the first lamp beads 100 or the second lamp beads 200 are arranged along the width direction of the lamp board 400, the spacing between two adjacent first lamp beads 100 is the first column spacing, and the spacing between two adjacent second lamp beads 200 is the second column spacing.

[0077] Basic equispacing refers to fixed spacings such as the first row spacing, the second row spacing, the first column spacing, and the second column spacing. The spacings formed after fine-tuning by the operators have actual values ​​that are not much different from the original fixed spacings, so the difference with the original fixed spacings can be ignored.

[0078] Reference Manual Attached Figure 1 In some embodiments, a plurality of first lamp beads 100 are disposed on a lamp board 400, two adjacent first lamp beads 100 are arranged equidistantly based on a first row spacing, and two adjacent first lamp beads 100 are arranged equidistantly based on a first column spacing; a plurality of second lamp beads 200, the second lamp beads 200 are disposed on a lamp board 400, two adjacent second lamp beads 200 are arranged equidistantly based on a second row spacing, and two adjacent second lamp beads 200 are arranged equidistantly based on a second column spacing, an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, and the angle between the geometric center of the first lamp bead 100 close to the coordinate origin and the X-axis or the Y-axis is an acute angle.

[0079] Specifically, based on the first row spacing and the first column spacing, multiple first lamp beads 100 are arranged equidistantly to form a first array, and based on the second row spacing and the second column spacing, multiple second lamp beads 200 are arranged equidistantly to form a second array. The second lamp beads 200 in the second array are arranged corresponding to the first lamp beads 100 in the first array, and an X-axis and Y-axis plane coordinate system is established with the geometric center of any second lamp bead 200 in the second array as the coordinate origin. The angle between the geometric center of the first lamp bead 100 corresponding to the second lamp bead 200 in the first array and the X-axis or Y-axis is an acute angle, that is, the angle range is greater than 0° and less than 90°.

[0080] Reference Manual Attached Figure 3 Overall, the first array is arranged obliquely relative to the second array, excluding some lamp beads closest to the lamp frame, and any remaining first lamp beads 100 are surrounded by four second lamp beads 200, or any remaining second lamp beads 200 are surrounded by four first lamp beads 100, thereby reducing the offset defects of the first lamp beads 100 or the second lamp beads 200 on the lamp board 400, and at the same time having a better uniformity performance.

[0081] Reference Manual Attached Figure 2In some embodiments, an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, and the angle between the geometric center of the first lamp bead 100 close to the coordinate origin and the X-axis or the Y-axis ranges from 30° to 60°; the angle between the geometric center of the first lamp bead 100 close to the coordinate origin and the X-axis or the Y-axis is 45°.

[0082] Specifically, an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, and the mutually perpendicular X-axis and Y-axis clamp the geometric center of the first lamp bead 100 closest to the second lamp bead 200. The angle between the geometric center of the first lamp bead 100 and the X-axis on one side ranges from 30° to 60°. Since the angle between the X-axis and the Y-axis is 90°, correspondingly, the angle between the geometric center of the first lamp bead 100 and the Y-axis on the other side ranges from 60° to 30°.

[0083] Alternatively, the angle between the geometric center of the first lamp bead 100 and the Y axis on one side ranges from 30° to 60°. Since the angle between the X axis and the Y axis is 90°, the corresponding angle between the geometric center of the first lamp bead 100 and the X axis on the other side ranges from 60° to 30°.

[0084] Among them, when the angle between the geometric center of the above-mentioned first lamp bead 100 and the X-axis or Y-axis on one side is 45°, since the angle between the X-axis and the Y-axis is 90°, accordingly, the angle range between the geometric center of the above-mentioned first lamp bead 100 and the Y-axis or X-axis on the other side is 45°.

[0085] Reference Manual Attached Figure 6 In the prior art, an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, and the geometric center of the first lamp bead 100 close to the coordinate origin is located on the X-axis or the Y-axis, that is, the angle between the geometric center of the first lamp bead 100 and the X-axis or the Y-axis is 0° or 90°; when any type of lamp bead is emitting light, the light output of the first lamp bead 100 or the second lamp bead 200 is biased to one side, while the other side is dimmer due to insufficient light output.

[0086] In comparison, the present application is based on the diagonal setting of the above-mentioned first lamp bead 100 and the second lamp bead 200, so that the offset degree of the first lamp bead 100 and the second lamp bead 200 on the lamp board 400 is reduced, thereby avoiding the first lamp bead 100 and the second lamp bead 200 from forming uneven shadows due to the difference in spacing, so that the light generated by any type of lamp bead is uniform.

[0087] Reference Manual Attached Figure 7 In some embodiments, the spacing between the first lamp bead 100 near the edge of the light board 400 and the edge of the light board 400 is a first row spacing or a first column spacing, and the spacing between the second lamp bead 200 near the edge of the light board 400 and the edge of the light board 400 is a second row spacing or a second column spacing.

[0088] Specifically, the inner contour line of the lamp housing or the lamp frame coincides with the edge line of the lamp board 400, that is, the spacing between the first lamp bead 100 close to the lamp frame and the lamp frame is the first row spacing or the first column spacing, and the spacing between the second lamp bead 200 close to the lamp frame and the lamp frame is the second row spacing or the second column spacing.

[0089] By setting the spacing between the first lamp bead 100 near the lamp frame and the lamp frame to the first row spacing or the first column spacing, the lighting range of the first lamp bead 100 in the horizontal or vertical direction covers the lamp frame, thereby avoiding the phenomenon of dark areas in the lamp frame; similarly, by setting the spacing between the second lamp bead 200 near the lamp frame and the lamp frame to the second row spacing or the second column spacing, the lighting range of the second lamp bead 200 in the horizontal or vertical direction covers the lamp frame, thereby ensuring that the lamp frame is evenly covered by light.

[0090] Reference Manual Attached Figure 7 and Figure 8 It should be noted that each second lamp bead 200 and the first lamp bead 100 closest to it are regarded as a module. For each module, the relevant values ​​that affect the overall illumination uniformity of the lighting lamp are set as Dx and Dy. Dx refers to the horizontal spacing of the same type of lamp beads on the lamp board 400, that is, Dx is the first column spacing or the second column spacing, and Dy refers to the longitudinal spacing of the same type of lamp beads on the lamp board 400, that is, Dy is the first row spacing or the second row spacing. Correspondingly, Dx and Dy also include the spacing between the first lamp bead 100 or the second lamp bead 200 close to the lamp frame and the lamp housing or the lamp frame.

[0091] For the above modules, if you want to get better illumination uniformity, if you take the maximum value of Dx and Dy as the reference value, the smaller the maximum value, the higher the uniformity; it can be understood that the smaller the maximum value, the closer Dx and Dy are, and the higher the uniformity.

[0092] Preferably, when an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, and the angle between the geometric center of the first lamp bead 100 closest to the coordinate origin and the X-axis or Y-axis is 45°, then Dx=Dy of the first lamp bead 100 and Dx=Dy of the second lamp bead 200.

[0093] Reference Manual Attached Figure 3, when an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, the angle between the geometric center of the first lamp bead 100 closest to the coordinate origin and the X-axis or the Y-axis is in the range of 30° to 60° (excluding the case where the angle is 45°); Dx of the first lamp bead 100 is not equal to Dy, Dx of the second lamp bead 200 is not equal to Dy, and the distance between any lamp bead close to the lamp frame and the lamp frame satisfies that Dx is not equal to Dy, but compared with other angles, the maximum value of Dx and Dy can be lower, so that Dx and Dy are close, and then the uniformity is higher.

[0094] Reference Manual Attached Figure 6 , and when an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, the angle between the geometric center of the first lamp bead 100 closest to the coordinate origin and the X-axis or Y-axis is 0° or 90°; Dx of the first lamp bead 100 is not equal to Dy, Dx of the second lamp bead 200 is not equal to Dy, and the distance between any lamp bead close to the lamp frame and the lamp frame satisfies Dx is not equal to Dy. At this time, the maximum value of Dx and Dy is relatively the highest, thereby maximizing the difference between Dx and Dy, and thus minimizing the uniformity.

[0095] If the minimum spacing between the first lamp bead 100 and the second lamp bead 200 is set to D (D is a fixed value, D is the distance between the geometric centers of the two lamp beads that are closest to each other), then for the two lamp beads, in the x and y directions, the relative angle between the lamp beads is set to θ, then the distance from the center of the two lamp beads to the geometric centers of the two lamp beads in the x and y directions is Dx'=1 / 2*D*sin(θ), Dy'=1 / 2*D*cos(θ), when θ=45°, Dx'=Dy' will be obtained, at which time the lamp beads are most evenly arranged and the light is most uniform.

[0096] Each second lamp bead 200 and the first lamp bead 100 closest to it are regarded as a module, and the modules on the lamp board 400 are evenly arranged, that is, DX and DY between the modules are equal, and because θ=45° of the first lamp bead 100 and the second lamp bead 200 in the module, Dx'=Dy' of the first lamp bead 100 and the second lamp bead 200; similarly, the lamp bead modules are also uniform, which further ensures uniform light output.

[0097] The two types of lamp beads have similar lamp bead arrangement spacing Dx and Dy, and the two adjacent lamp bead modules also have similar arrangement spacing. The two types of lamp beads obtain balanced lampshade uniformity performance. In extreme cases, if θ=0 or θ=90°, Dx' or Dy'=1 / 2*D, one of the lamp beads will obtain the best uniformity performance, while the other will obtain the worst performance.

[0098] Based on the above analysis, for the relative setting of the two lamp beads, when the relative angle between the two axes is 0° or 90°, one of the lamp beads will have the best uniformity performance, while the other lamp bead will have the worst uniformity performance; and when the relative angle between the two axes is set to an acute angle in the present application, that is, the relative angle range between the two axes is set to be greater than 0° and less than 90°, the illumination uniformity of any type of lamp bead when illuminated can be relatively improved; further, the present application sets the relative angle range between the two axes to be 30° to 60°, which can make the illumination uniformity of any type of lamp bead higher when illuminated; further, setting the relative angle between the two axes to 45° can make the illumination uniformity of any type of lamp bead when illuminated can be the highest.

[0099] In some embodiments, a portion of the first lamp beads 100 and the second lamp beads 200 closest thereto form a first module in a first oblique downward arrangement or a first oblique upward arrangement, and another portion of the first lamp beads 100 and the second lamp beads 200 closest thereto form a second module in a second oblique downward arrangement or a second oblique upward arrangement. The first module and the second module are alternately arranged on the lamp board 400, the first oblique downward arrangement is different from the second oblique downward arrangement and cooperate with each other, and the first oblique upward arrangement is different from the second oblique upward arrangement and cooperate with each other.

[0100] Specifically, the multiple first lamp beads 100 and the multiple second lamp beads 200 on the lamp board 400 are divided into a first part or a second part; an X-axis and Y-axis coordinate system is established with the geometric center of any first lamp bead 100 in the first part as the coordinate origin, and the geometric center of the second lamp bead 200 closest to the coordinate origin is located in the first quadrant or the second quadrant of the coordinate system to form a first oblique upward arrangement, or the geometric center of the second lamp bead 200 closest to the coordinate origin is located in the third quadrant or the fourth quadrant of the coordinate system to form a first oblique downward arrangement, thereby forming a first module based on the arrangement of the first oblique upward arrangement or the first oblique downward arrangement.

[0101] In addition, an X-axis and Y-axis coordinate system is established with the geometric center of any first lamp bead 100 in the second part as the coordinate origin, and the geometric center of the second lamp bead 200 closest to the coordinate origin is located in the first quadrant or the second quadrant of the coordinate system to form a second oblique upward arrangement, or, the geometric center of the second lamp bead 200 closest to the coordinate origin is located in the third quadrant or the fourth quadrant of the coordinate system to form a second oblique downward arrangement, thereby forming a second module based on the second oblique upward arrangement or the second oblique downward arrangement; the first module and the second module are cross-arranged on the lamp board 400 to make the lighting more uniform when any type of lamp bead is illuminated.

[0102] In some embodiments, an X-axis and Y-axis coordinate system is established with the geometric center of any first lamp bead 100 in the first module as the coordinate origin, and when the geometric center of the second lamp bead 200 closest to the coordinate origin in the first module is located in the first quadrant of the coordinate system to form a first oblique upward arrangement, an X-axis and Y-axis coordinate system is established with the geometric center of any first lamp bead 100 in the second module as the coordinate origin, and the corresponding second lamp bead 200 closest to the coordinate origin in the second module is located in the second quadrant of the coordinate system to form a second oblique upward arrangement, so that the light emission of any type of lamp bead is more uniform, and the light mixing of two adjacent lamp beads with different parameter characteristics is also uniform.

[0103] In some embodiments, an X- and Y-axis coordinate system is established with the geometric center of any first lamp bead 100 in the first module as the coordinate origin, and when the geometric center of the second lamp bead 200 closest to the coordinate origin in the first module is located in the second quadrant of the coordinate system to form a first oblique upward arrangement, an X- and Y-axis coordinate system is established with the geometric center of any first lamp bead 100 in the second module as the coordinate origin, and the corresponding second lamp bead 200 closest to the coordinate origin in the second module is located in the first quadrant of the coordinate system to form a second oblique upward arrangement, so that the light emission of any type of lamp bead is more uniform, and the light mixing of two adjacent lamp beads with different parameter characteristics is also uniform.

[0104] In some embodiments, an X-axis and Y-axis coordinate system is established with the geometric center of any first lamp bead 100 in the first module as the coordinate origin, and when the geometric center of the second lamp bead 200 closest to the coordinate origin in the first module is located in the third quadrant of the coordinate system to form a first downward oblique arrangement, an X-axis and Y-axis coordinate system is established with the geometric center of any first lamp bead 100 in the second module as the coordinate origin, and the corresponding second lamp bead 200 closest to the coordinate origin in the second module is located in the fourth quadrant of the coordinate system to form a second downward oblique arrangement, so that the light emission of any type of lamp bead is more uniform, and the light mixing of two adjacent lamp beads with different parameter characteristics is also uniform.

[0105] Reference Manual Attached Figure 1 In some embodiments, an X-axis and Y-axis coordinate system is established with the geometric center of any first lamp bead 100 in the first module as the coordinate origin, and when the geometric center of the second lamp bead 200 closest to the coordinate origin in the first module is located in the fourth quadrant of the coordinate system to form a first oblique downward arrangement, an X-axis and Y-axis coordinate system is established with the geometric center of any first lamp bead 100 in the second module as the coordinate origin, and the corresponding second lamp bead 200 closest to the coordinate origin in the second module is located in the third quadrant of the coordinate system to form a second oblique downward arrangement, so that the light emission of any type of lamp bead is more uniform, and the light mixing of two adjacent lamp beads with different parameter characteristics is also uniform.

[0106] It should be noted that the principle of the above arrangement is that even if the first lamp bead 100 and the second lamp bead 200 on the lamp board 400 are arranged diagonally to achieve the technical effect of making Dx=Dy, or Dx and Dy close, the light output of the lighting lamp may still have the problem that the first color light is biased toward the upper left corner of the lamp board 400, and the second color light is biased toward the lower right corner of the lamp board 400; or, there may be a problem that the second color light is biased toward the upper left corner of the lamp board 400, and the first color light is biased toward the lower right corner of the lamp board 400.

[0107] The first oblique downward arrangement is different from the second oblique downward arrangement and cooperates with each other, that is, if the first module uses the first oblique downward arrangement, the second module uses the second oblique downward arrangement, and the first oblique downward arrangement makes the geometric center of the second lamp bead 200 of the first module located in the third quadrant of the coordinate system, then the first oblique downward arrangement makes the geometric center of the second lamp bead 200 of the second module located in the fourth quadrant of the coordinate system, and vice versa.

[0108] The first oblique upward arrangement is different from the second oblique upward arrangement and cooperates with each other, that is, if the first module uses the first oblique upward arrangement, then the second module uses the second oblique upward arrangement, and the first oblique upward arrangement makes the geometric center of the second lamp bead 200 of the first module located in the first quadrant of the coordinate system, then the first oblique upward arrangement makes the geometric center of the second lamp bead 200 of the second module located in the second quadrant of the coordinate system, and vice versa.

[0109] By arranging the first oblique upward arrangement to be different from and coordinated with the second oblique upward arrangement, or arranging the first oblique downward arrangement to be different from and coordinated with the second oblique downward arrangement, and arranging the first module and the second module crosswise, the polarization phenomena of the first module and the second module can be complementary, thereby making the overall light output uniform.

[0110] In some embodiments, the first lamp bead 100 and the second lamp bead 200 closest to it form a first unit or a second unit in different arrangements, and multiple first units form a first module based on a first row spacing or a second row spacing, and multiple second units corresponding to the first units form a second module based on the first row spacing or the second row spacing; the first module and the second module are cross-arranged on the light board 400.

[0111] Specifically, an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, the angle between the geometric center of the first lamp bead 100 close to the coordinate origin and the X-axis or the Y-axis is an acute angle, and the above-mentioned first lamp bead 100 and the second lamp bead 200 closest to it are arranged in different ways to form a first unit or a second unit, wherein the arrangement of the first unit is arranged diagonally upward or diagonally downward, and the corresponding arrangement of the second unit is arranged diagonally upward or diagonally downward; multiple first units are based on the first row spacing or the second row spacing to form a first module arranged vertically on the lamp board 400, and multiple second units correspond to the first units based on the first row spacing or the second row spacing to form a second module arranged vertically on the lamp board 400, and the first module and the second module are cross-arranged on the lamp board 400, that is, cross-arranged in the horizontal direction of the lamp board 400.

[0112] In some embodiments, the first lamp bead 100 and the second lamp bead 200 closest to it form a first unit or a second unit in different arrangements, and multiple first units form a third module based on the first column spacing or the second column spacing, and multiple second units corresponding to the first units form a fourth module based on the first column spacing or the second column spacing; the third module and the fourth module are cross-arranged on the lamp board 400.

[0113] Specifically, an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 as the coordinate origin, the angle between the geometric center of the first lamp bead 100 close to the coordinate origin and the X-axis or the Y-axis is an acute angle, and the above-mentioned first lamp bead 100 and the second lamp bead 200 closest to it are arranged in different ways to form a first unit or a second unit, wherein the arrangement of the first unit is arranged diagonally upward or diagonally downward, and the corresponding arrangement of the second unit is arranged diagonally upward or diagonally downward; multiple first units are based on the first column spacing or the second column spacing to form a third module arranged horizontally on the lamp board 400, and multiple second units correspond to the first units based on the first column spacing or the second column spacing to form a fourth module arranged horizontally on the lamp board 400, and the third module and the fourth module are cross-arranged on the lamp board 400, that is, cross-arranged in the longitudinal direction of the lamp board 400.

[0114] It should be noted that the X- and Y-axis coordinate systems are established with the geometric center of the second lamp bead 200 as the coordinate origin. The geometric center of the first lamp bead 100 is relatively located in the third quadrant or the fourth quadrant, which is arranged diagonally downward, and the geometric center of the first lamp bead 100 is relatively located in the first quadrant or the second quadrant, which is arranged diagonally upward.

[0115] In some embodiments, an X-axis coordinate system is established with the geometric center of any second lamp bead 200 in the first unit as the coordinate origin, and the geometric center of the first lamp bead 100 close to the coordinate origin is located in the third quadrant or the fourth quadrant of the coordinate system, and an X-axis coordinate system is established with the geometric center of any second lamp bead 200 in the second unit as the coordinate origin, and the geometric center of the first lamp bead 100 close to the coordinate origin is correspondingly located in the first quadrant or the second quadrant of the coordinate system;

[0116] Alternatively, an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 in the first unit as the coordinate origin, and the geometric center of the first lamp bead 100 close to the coordinate origin in the first unit is located in the first quadrant or the second quadrant of the coordinate system; and an X-axis and Y-axis coordinate system is established with the geometric center of any second lamp bead 200 in the second unit as the coordinate origin, and the geometric center of the first lamp bead 100 close to the coordinate origin is correspondingly located in the third quadrant or the fourth quadrant of the coordinate system.

[0117] Specifically, an X-axis coordinate system is established with the geometric center of any second lamp bead 200 in the first unit as the coordinate origin, and the geometric center of the first lamp bead 100 close to the coordinate origin is located in the third quadrant of the coordinate system to form a downward oblique arrangement; and an X-axis coordinate system is established with the geometric center of any first lamp bead 100 in the second unit as the coordinate origin, and the geometric center of the second lamp bead 200 close to the coordinate origin is correspondingly located in the second quadrant of the coordinate system to form an upward oblique arrangement.

[0118] When an X-axis coordinate system is established with the geometric center of any second lamp bead 200 in the first unit as the coordinate origin, the geometric center of the first lamp bead 100 close to the coordinate origin is located in the fourth quadrant of the coordinate system to form a downward oblique arrangement; and when an X-axis coordinate system is established with the geometric center of any first lamp bead 100 in the second unit as the coordinate origin, the geometric center of the second lamp bead 200 close to the coordinate origin is correspondingly located in the first quadrant of the coordinate system to form an upward oblique arrangement.

[0119] An X-axis coordinate system is established with the geometric center of any second lamp bead 200 in the first unit as the coordinate origin, and the geometric center of the first lamp bead 100 close to the coordinate origin is located in the first quadrant of the coordinate system to form an upward oblique arrangement; and an X-axis coordinate system is established with the geometric center of any first lamp bead 100 in the second unit as the coordinate origin, and the geometric center of the second lamp bead 200 close to the coordinate origin is correspondingly located in the fourth quadrant of the coordinate system to form a downward oblique arrangement.

[0120] An X-axis coordinate system is established with the geometric center of any second lamp bead 200 in the first unit as the coordinate origin, and the geometric center of the first lamp bead 100 close to the coordinate origin is located in the second quadrant of the coordinate system to form an upward oblique arrangement; and an X-axis coordinate system is established with the geometric center of any first lamp bead 100 in the second unit as the coordinate origin, and the geometric center of the second lamp bead 200 close to the coordinate origin is correspondingly located in the third quadrant of the coordinate system to form a downward oblique arrangement.

[0121] Based on the arrangement of the first unit and the second unit, the first unit in the first module is arranged based on the first row spacing or the second row spacing, and the second unit in the second module corresponds to the first unit arranged based on the first row spacing or the second row spacing, so that the edge monochromatic light areas of the first module and the second module overlap each other; based on the arrangement of the first unit and the second unit, the first unit in the third module is arranged based on the first column spacing or the second column spacing, and the second unit in the fourth module corresponds to the first unit arranged based on the first column spacing or the second column spacing, so that the edge monochromatic light areas of the third module and the fourth module overlap each other, thereby achieving uniform illumination when any type of lamp bead is illuminated.

[0122] In some embodiments, any first lamp bead 100 and the second lamp bead 200 closest thereto are arranged in a compact manner to minimize the distance between the two, thereby increasing the density of the lamp bead arrangement, thereby increasing the illumination of the lamp and making the mixed light more uniform.

[0123] In some embodiments, the first module and the second module, and the third module and the fourth module are evenly and equidistantly distributed.

[0124] Furthermore, a preset distance is set between the first module and the second module, and between the third module and the fourth module, and the preset distance includes a fixed distance and a compensation amount.

[0125] Specifically, in actual applications, the first module and the second module, and the third module and the fourth module should be equidistantly and evenly distributed under an ideal model. However, in actual implementation, due to other factors, the uniform and equidistant distribution may not be the best effect. Potential influencing factors include the consistency of the lamp beads, the distance between the lamp beads and the light-emitting surface, the reflectivity of different structures of the lamp board 400, the distance between the lamp beads and the boundary, and so on. Therefore, the uniform arrangement of the lamp beads on the lamp board 400 does not necessarily mean the best visual uniformity of light output for the user. In order to further optimize the visual uniformity of light output for the user, further fine-tuning is required. Therefore, a fixed spacing should be set based on actual conditions. The fixed spacing includes a first row spacing, a first column spacing, a second row spacing, and a second column spacing. Furthermore, different compensation amounts are selected for adjustment based on the fixed spacing. After fine-tuning, it is referred to as basically equidistant or basically equivalent spacing in the present invention.

[0126] In some embodiments, the compensation amount is adjusted based on software simulation to achieve visually uniform light output.

[0127] A same fixed spacing S is preset to make each module or lamp bead evenly arranged, and a compensation amount a1, a2, a3, a4...a4, a3, a2, a1 is set for each spacing, so that the spacing of each module unit is S+a1, S+a2, S+a3, S+a4......S+a4, S+a3, S+a2, S+a1, where a1, a2, a3, a4..... is an arithmetic progression of negative numbers. Through software simulation and comparison, the optimal value of this sequence can be obtained to get the compensation amount. Specific embodiment 2

[0136] The present application also provides a light source assembly, which differs from the specific embodiment 1 in that the first spacing and the second spacing are further defined, and the light source assembly includes a substrate and a plurality of light-emitting units, wherein the plurality of light-emitting units are arranged on the substrate, and a first spacing is provided between two adjacent light-emitting units; any light-emitting unit further includes a first lamp bead 100 and a second lamp bead 200, and a second spacing is provided between the first lamp bead 100 and the second lamp bead 200, and the first spacing is greater than the second spacing, and the first lamp bead 100 and the second lamp bead 200 are lamp beads with different parameter characteristics, and / or the switching states of the first lamp bead 100 and the second lamp bead 200 are mutually exclusive; the center line of the first lamp bead 100 and the second lamp bead 200 constitutes the center line of the light-emitting unit, and the center line of the light-emitting unit is inclined relative to the length direction or width direction of the substrate, and the center lines of two adjacent light-emitting units are parallel to or cross each other.

[0137] Specifically, the substrate is a type of printed circuit board (PCB), and the material of the substrate includes but is not limited to aluminum, which is used to dissipate heat for the lamp beads. The first spacing refers to the spacing between two adjacent light-emitting units, and the second spacing refers to the spacing between the first lamp bead 100 and the second lamp bead 200 in any light-emitting unit. By making the first spacing greater than the second spacing, the light distribution between each light-emitting unit can be effectively adjusted to avoid light overlap or dark areas, thereby improving the overall lighting effect, reducing glare, making users more comfortable when using it, and less likely to cause visual fatigue, and increasing the configurable space between the two light-emitting units, cooperating with technical personnel to fine-tune the lamp beads or increase the lamp bead fill light.

[0138] In some embodiments, the parameter characteristics include spectrum, luminous color, color temperature, luminous angle and / or packaging form; for details, please refer to the description in the first specific embodiment, which will not be repeated here.

[0139] In some embodiments, the center line of the light emitting unit is inclined at an angle ranging from 30° to 60° relative to the length direction or the width direction of the substrate; for details, please refer to the description in the first specific embodiment, which will not be repeated here.

[0140] Reference Figure 2 In some embodiments, the center line of the light emitting unit is inclined at an angle of 45° relative to the length direction or the width direction of the substrate; for details, please refer to the description in the first specific embodiment, which will not be repeated here.

[0141] In some embodiments, the light source assembly further includes a third lamp bead, which is disposed between two adjacent light-emitting units, and the third lamp bead has the same parameter characteristics as the first lamp bead 100 or the second lamp bead 200 .

[0142] Specifically, based on the fact that the first spacing is greater than the second spacing, when the light from the first lamp bead 100 or the second lamp bead 200 is weak, the third lamp bead is installed on the first spacing to supplement the light, so the parameter characteristics of the third lamp bead are the same as those of the first lamp bead 100 or the second lamp bead 200; the third lamp bead can be controlled independently or together with the first lamp bead or the second lamp bead.

[0144] Specifically, the multiple light-emitting units in the light-emitting lamp group are arranged along the length direction of the substrate, and the multiple light-emitting lamp groups are arranged along the width direction of the substrate, so that the entire substrate is evenly covered with multiple light-emitting units, thereby improving the overall lighting effect of all light sources on the substrate.

[0145] Reference Figure 1 In some embodiments, a plurality of light emitting lamp groups are arranged in parallel on a substrate to make the light source composed of the plurality of light emitting lamp groups emit light uniformly as a whole. Specific embodiment 4

[0147] Reference Figure 1 and Fig. 9 The present application also provides a direct-down type light-emitting lighting device, which is different from the specific embodiment 3 in that the light-emitting unit includes a first lamp bead 100, a second lamp bead 200 and a lens 300 respectively arranged outside the two lamp beads, and the direct-down type light-emitting lighting device includes a lampshade and a light source assembly, the light source assembly is arranged in the lampshade, and the light source assembly further includes a substrate and a lamp group module; wherein the lamp group module is arranged on the substrate, and the lamp group module includes a plurality of light-emitting units arranged along the length direction of the substrate, and a first spacing is spaced between two adjacent light-emitting units; any light-emitting unit further The invention comprises a first lamp bead 100, a second lamp bead 200 and a lens 300 respectively covering the two lamp beads, the first lamp bead 100 and the second lamp bead 200 are separated by a second interval, the first interval is greater than the second interval, the first lamp bead 100 and the second lamp bead 200 are lamp beads with different parameter characteristics, and / or the switching states of the first lamp bead 100 and the second lamp bead 200 are mutually exclusive; the center line of the first lamp bead 100 and the second lamp bead 200 constitutes the center line of the light-emitting unit, and the angle between the center line of the light-emitting unit and the length or width direction of the substrate is an acute angle.

[0148] Specifically, since the first lamp bead 100 and the second lamp bead 200 in any light-emitting unit are both covered with a lens 300, compared with the situation in which no lens 300 is covered in the specific embodiment three, the first spacing between two adjacent light-emitting units is larger, and the second spacing between the first lamp bead 100 and the second lamp bead 200 in any light-emitting unit is larger, so as to be used for the installation of the lens 300. By making the angle between the center line of the light-emitting unit and the length or width direction of the substrate an acute angle, the space on the substrate can be more effectively utilized, the light-emitting units can be arranged more evenly and densely, and dark areas caused by excessively large first spacing and second spacing can be avoided, thereby improving the overall lighting effect.

[0149] In some embodiments, the parameter characteristics include spectrum, luminous color, color temperature, luminous angle and / or packaging form. For details, please refer to the description in the first specific embodiment, which will not be repeated here.

[0150] In some embodiments, the center line of the light emitting unit is inclined at an angle ranging from 30° to 60° relative to the length direction or the width direction of the substrate. For details, please refer to the description in the first specific embodiment, which will not be repeated here.

[0151] In some embodiments, the center line of the light emitting unit is inclined at an angle of 45° relative to the length direction or the width direction of the substrate. For details, please refer to the description in the first specific embodiment, which will not be repeated here.

[0152] In some embodiments, the first lamp bead 100 near the edge of the substrate is spaced apart from the edge of the substrate by a first interval, two adjacent first lamp beads 100 in the lamp group module are spaced apart by a second interval, and the first interval is equal to or substantially equal to the second interval; and the second lamp bead 200 near the edge of the substrate is spaced apart from the edge of the substrate by a third interval, two adjacent second lamp beads 200 in the lamp group module are spaced apart by a fourth interval, and the third interval is equal to or substantially equal to the fourth interval.

[0153] Specifically, based on the illumination radius of the first lamp bead 100 being the first interval, the illumination radius of the first lamp bead 100 in the horizontal or vertical direction covers the edge of the substrate to avoid the phenomenon of dark areas at the edge of the substrate; similarly, based on the illumination radius of the second lamp bead 200 being the second interval, the illumination range of the second lamp bead 200 in the horizontal or vertical direction covers the edge of the substrate, thereby ensuring that the edge of the substrate is evenly covered by light when illuminated by any type of lamp bead.

[0154] Reference Figures 3 to 5 In some embodiments, the lamp group module further includes a first lamp group and a second lamp group, the first lamp group and the second lamp group include a plurality of light-emitting units arranged along the length direction of the substrate, and the center line of any light-emitting unit in the first lamp group and the center line of any light-emitting unit in the second lamp group are parallel or perpendicular to each other.

[0155] Specifically, when the center line of any light-emitting unit in the first lamp group is parallel to the center line of any light-emitting unit in the second lamp group, multiple light-emitting units can be densely arranged on the substrate, thereby improving the overall lighting effect; when the center line of any light-emitting unit in the first lamp group is perpendicular to the center line of any light-emitting unit in the second lamp group, the technical effect of a dark area appearing on one side of the complementary lamp group can be achieved between the first lamp group and the second lamp group.

[0156] Reference Figure 4 In some embodiments, the lamp group module further includes a first lamp group and a second lamp group, the first lamp group and the second lamp group include a plurality of light-emitting units arranged along the length direction of the substrate, the light-emitting units in the first lamp group and the second lamp group are respectively arranged in an axisymmetric manner based on a symmetry axis parallel to the length direction of the substrate, and the first lamp bead 100 and the second lamp bead 200 in the first lamp group and the second lamp bead 200 and the first lamp bead 100 in the second lamp group correspond to each other based on the symmetry axis.

[0157] Specifically, since the first lamp bead 100 and the second lamp bead 200 in the first lamp group or the second lamp group are arranged in a manner that each is biased towards one side of the lamp group, a defect of only one light color occurs on one side of the lamp group; and based on the axially symmetrical arrangement of the light-emitting units in the first lamp group and the second lamp group, the first lamp bead 100 and the second lamp bead 200 in the first lamp group and the second lamp group are staggered and correspond to each other.

[0158] Reference Figure 3 In some embodiments, the lamp group module further includes a first lamp group and a second lamp group, the first lamp group and the second lamp group include a plurality of light-emitting units arranged along the length direction of the substrate, and the arrangement of the light-emitting units in the first lamp group and the second lamp group and the inclination angle of the center lines of the light-emitting units relative to the length direction or the width direction of the substrate are the same.

[0159] Specifically, based on the arrangement of the light-emitting units in the first lamp group and the second lamp group and the same inclination angle of the center lines of the light-emitting units relative to the length direction or the width direction of the substrate, the first lamp beads 100 or the second lamp beads 200 close to the edge of the substrate are excluded, and any color of lamp beads in the first lamp group or the second lamp group are surrounded by four adjacent lamp beads of different colors, thereby achieving a technical effect of uniform light output.

[0160] Reference Figure 5 In some embodiments, a center line of any light emitting unit in the first light group or the second light group is perpendicular to a center line of an adjacent light emitting unit.

[0161] Specifically, based on the arrangement of the light-emitting units in the first lamp group and the second lamp group and the same inclination angle of the center lines of the light-emitting units relative to the length direction or the width direction of the substrate, and the center line of any light-emitting unit in the first lamp group or the second lamp group is perpendicular to the center line of the adjacent light-emitting unit, excluding the first lamp bead 100 or the second lamp bead 200 close to the edge of the substrate, any two closest lamp beads of the same color in the first lamp group or the second lamp group are surrounded by four adjacent lamp beads of different colors, thereby achieving a technical effect of uniform light output.

[0162] The present application provides a lighting lamp, a lighting device, a light source assembly and a direct-down lighting device. By arranging the first lamp bead 100 and the second lamp bead 200 diagonally opposite to each other, the lighting of the first lamp bead 100 and the second lamp bead 200 is uniform, and the light of the first lamp bead 100 or the second lamp bead 200 is avoided to be biased to opposite ends on the lamp board 400, and at the same time, a relatively good uniformity performance is achieved; by arranging the first lamp bead 100 and the second lamp bead 200 diagonally opposite to each other at 45°, the lighting effect is further made precise and uniform; by staggering the first module and the second module or the third module and the fourth module on the lamp board 400, the polarization defects of the two modules are compensated for each other, so that the overall light output is uniform; by setting the distance between the first lamp bead 100 and the lamp frame, and the distance between the second lamp bead 200 and the lamp frame, the phenomenon of dark areas in the lamp frame, especially in the corners, is avoided.
