Description

Camera Flat Panel Light

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 28, 2023, with application number 202321674995.0 and application name “Camera Flat Panel Lamp”, and the Chinese patent application filed with the China Patent Office on June 28, 2023, with application number 202310782204.4 and application name “Camera Flat Panel Lamp”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of photographic and video lighting equipment, and in particular to a flat panel light for video recording. Background Art

[0003] In some existing indoor studios and live broadcast rooms, flat panel cameras are often used as a light source. These cameras feature a light-emitting surface with multiple LED beads arranged in an array. Due to the increasing demand for color in flat panel cameras, some manufacturers package different colored light-emitting chips within each LED bead, allowing them to emit different colors after mixing light to meet different usage requirements.

[0004] At present, the installation positions of different light-emitting chips inside each lamp bead are fixed. For example, the blue light-emitting chip is installed in the upper left corner of the lamp bead, and the green light-emitting chip is installed in the lower right corner of the lamp bead. However, since the lamp beads are now installed on the light board in a uniform arrangement, after the lamp beads are installed on the light board, the superposition of multiple LED lamp beads makes the light emission difference of the flat panel light more obvious, resulting in uneven color in some areas of the flat panel light. For example, the light emitted by the light board will be bluish in the upper left corner and greenish in the lower right corner, seriously affecting the effect of photography and videography.

[0005] Utility Model Content

[0006] The purpose of the utility model is to solve the technical problem in the prior art that after the lamp beads are installed on the lamp panel, the superposition of multiple LED lamp beads makes the luminous difference of the flat panel lamp more obvious, resulting in uneven color in some areas of the flat panel lamp, which seriously affects the effect of photography and videography.

[0007] In order to solve the above technical problems, the utility model provides a camera flat panel light, which includes a lamp board and lamp beads, and there are multiple lamp beads, and the multiple lamp beads are arranged in an array on the lamp board; each of the lamp beads includes a main body and a plurality of chips arranged on the main body, and the multiple chips can be divided into multiple groups according to the different luminous colors of their own. The luminous colors of each group of chips are the same, and the multiple chips are arranged in a central symmetrical manner on the main body; wherein one side edge of the main body is set as a reference edge; the angle between the line connecting the center point of the main body of each lamp bead and the center point of the lamp board and the reference edge of the main body of the lamp bead is the reference angle, and the size of the reference angle formed by each lamp bead on the lamp board is the same.

[0008] Optionally, the reference angle is no greater than 90°.

[0009] Optionally, the reference angle is 90°.

[0010] Optionally, the lamp beads are arranged in a central symmetrical manner about the center point of the lamp board.

[0011] Optionally, center points of the main bodies of the plurality of lamp beads located in the same horizontal row are on the same straight line.

[0012] Optionally, center points of the main bodies of the plurality of lamp beads located in the same vertical column are on the same straight line.

[0013] Optionally, the chips on each of the lamp beads are arranged in a central symmetrical manner about the center point of the main body.

[0014] Optionally, each of the lamp beads includes four chips, and the four chips are respectively one G chip, one B chip and two R chips.

[0015] Optionally, the four chips are arranged in a central symmetrical manner about a center point of the main body.

[0016] Optionally, the main body is a square structure, and the two R chips are arranged opposite to each other.

Each of the lamp beads includes a main body and a plurality of chips arranged on the main body. The plurality of chips can be divided into a plurality of groups according to the different luminous colors of the chips themselves. The luminous colors of the chips in each group are the same, and the plurality of chips are arranged in a centrally symmetrical manner on the main body. On the light board, the reference angles formed by all the lamp beads are the same in size. This arrangement enables all the lamp beads to be arranged in a centrally symmetrical manner with respect to the center point of the light board. Combined with the arrangement that the plurality of groups of chips have a plurality of different colors and the plurality of chips are arranged in a centrally symmetrical manner on the main body, the light emitted by the plurality of different colored chips on the light board can be evenly mixed to reduce the difference after the superposition of light of different colors, so that the overall color of the camera flat panel light is more uniform, thereby effectively improving the effect of photography and videography.

DETAILED DESCRIPTION

[0029] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative in nature and not to limit the present invention.

[0030] In the description of this application, it should be understood that in the embodiments shown in the drawings, indications of directions or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions will also change accordingly.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0032] 1 to 5 , an embodiment of the present application provides a flat panel camera light 100 , which is commonly used in indoor studios and live broadcast rooms as a camera light source to provide lighting for live filming. The flat panel camera light 100 of this embodiment includes a light board 10 and light beads 20 .

[0033] Multiple lamp beads 20 are provided and arranged in an array on the light board 10. The length of the light board 10 defines the horizontal rows of the lamp beads 20, while the width of the light board 10 defines the vertical rows of the lamp beads 20. Each lamp bead 20 comprises a main body 21 and a plurality of chips 22 mounted on the main body 21. The chips 22 are divided into groups based on their respective emission colors. Each group of chips 22 emits the same color, and the chips 22 are arranged symmetrically around the main body 21.

[0034] One side of the main body 21 is defined as the reference side. The angle formed by the line connecting the center point of the main body 21 of each lamp bead 20 and the center point A of the lamp board 10 and the reference side 2101 of the main body 21 of the lamp bead 20 is defined as the reference angle α. The reference angle α formed by each lamp bead 20 on the lamp board 10 is the same.

[0035] In this embodiment, the light board 10 has a quadrilateral structure, with four sides comprising a first side 11, a second side 12, a third side 13, and a fourth side 14, which are sequentially connected. The first side 11 and the third side 13 are arranged opposite and parallel to each other, while the second side 12 and the fourth side 14 are arranged opposite and parallel to each other. The first and third sides 11, 13 extend in the length direction of the light board 10, while the second and fourth sides 12, 14 extend in the width direction of the light board 10. The lamp beads 20 are arranged in an array on the light board 10. The lamp beads 20 are arranged in a horizontal row along the length direction of the light board 10, i.e., along the first and third sides 11, 13, and in a vertical row along the width direction of the light board 10, i.e., along the second and fourth sides 12, 14, respectively. The light board 10 provides a mounting location for the lamp beads 20 and facilitates the integrated assembly of multiple lamp beads 20. A signal input terminal and a signal output terminal can be set on each side of the light board 10. During actual production and assembly, the signal input terminal and signal output terminal on any side can be selected for wiring according to the assembly situation, thereby ensuring the flexibility of wiring, simplifying the wiring of the circuit on the camera flat panel light 100, and optimizing the installation of the lamp beads 20.

[0036] In other examples of this embodiment, in addition to the quadrilateral structure of the light board 10 shown in this embodiment, the light board 10 can also be a regular shape such as a circle, triangle, ellipse, pentagon, or other irregular shapes to adapt to different usage requirements and usage environments.

[0037] Furthermore, the light board 10 of this embodiment is provided with a plurality of lamp beads 20, which are arranged in an array on the light board 10. In this embodiment, the lamp beads 20 in each horizontal row are arranged at equal intervals, and the lamp beads 20 in each vertical row are arranged at equal intervals. Each lamp bead 20 includes a main body 21 and a plurality of chips 22. The main body 21 is provided on the light board 10, and the chips 22 are provided on the surface of the main body 21 facing away from the light board 10.

[0038] In this embodiment, the main body 21 has a square structure, and each lamp bead 20 includes four chips 22, which are arranged symmetrically about the center point of the main body 21. The four chips 22 are a G chip 221, a B chip 222, and two R chips 223. The R chip 223 is a red LED chip 22, the G chip 221 is a green LED chip 22, and the B chip 222 is a blue LED chip 22.

[0039] The main body 21 of this embodiment has a square structure, with two G chips 221 positioned opposite each other and arranged on the same diagonal of the square structure. This arrangement allows the red-emitting R chip 223, the green-emitting G chip 221, and the blue-emitting B chip 222 to be dispersed, avoiding the centralized placement of the red-emitting R chip 223. This reduces luminous variations after superposition of light, ensuring color uniformity and the lighting effect of the camera flat panel light 100.

[0040] In other examples of this embodiment, the chip 22 can also be set to two, such as chips 22 for cold and warm colors respectively; it can also be set to three, such as R chip 223, B chip 222 and G chip 221 respectively; it can also be set to four, such as including two B chips 222, one R chip 223 and one G chip 221, or including two G chips 221, one B chip 222 and one R chip 223; five chips 22, six chips 22, etc. can also be set according to actual usage requirements.

[0041] In addition, in other examples, the outer contour of the main body 21 can also be a regular polygon of other shapes, such as an equilateral triangle, a regular pentagon, a regular hexagon, etc. The shape of the main body 21 can be determined according to different designs and usage requirements and is not limited here.

[0042] In this embodiment, the main body 21 of the lamp bead 20 has a square structure, and the four sides of the main body 21 are a first main body side 211, a second main body side 212, a third main body side 213, and a fourth main body side 214, which are connected in sequence. The first main body side 211 and the third main body side 213 are arranged opposite and parallel to each other, and the second main body side 212 and the fourth main body side 214 are arranged opposite and parallel to each other.

[0043] The reference edge in this embodiment is the second main body edge 212 . In other examples of this embodiment, the reference edge may also be one of the first main body edge 211 , the third main body edge 213 , or the fourth main body edge 214 .

[0044] As shown in FIG3 , each lamp bead 20 is positioned on the light board 10 in its initial installation state. In this initial state, the first main body edge 211 of the main body portion 21 of the lamp bead 20 is positioned toward the first side 11 of the light board 10 and the two are relatively parallel, the third main body edge 213 of the main body portion 21 is positioned toward the third side 13 of the light board 10 and the two are relatively parallel, the second main body edge 212 of the main body portion 21 is positioned toward the second side 12 of the light board 10 and the two are relatively parallel, and the fourth main body edge 214 of the main body portion 21 is positioned toward the fourth side 14 of the light board 10 and the two are relatively parallel.

[0045] In this embodiment, in the initial state, the center points of the main bodies 21 of all the lamp beads 20 in a horizontal row are on the same straight line, and the center points of the main bodies 21 of all the lamp beads 20 in a vertical row are on the same straight line.

[0046] After the initial state of each lamp bead 20 is determined, each lamp bead 20 is rotated clockwise or counterclockwise around the center point A of its own lamp board 10 by a set angle to obtain a final state.

[0047] In this embodiment, each lamp bead 20 rotates clockwise around the center point A of its own lamp board 10. In other examples, each lamp bead 20 rotates counterclockwise around the center point A of its own lamp board 10. The rotation direction of the lamp bead 20 is not limited to a single direction, as long as the rotation direction of multiple lamp beads 20 in the same horizontal row and the rotation direction of multiple lamp beads 20 in the same vertical row are the same.

[0048] In the final state, i.e., the state of the final product, as shown in conjunction with Figures 1, 4, and 5, the side of the main body 21 of the lamp beads 20 located in the horizontal row that is close to the center point of the lamp board 10, i.e., the second main body side 212, is the reference side 2101; the side of the main body 21 of the lamp beads 20 located in the vertical row that is close to the center point of the lamp board 10, i.e., the second main body side 212, is the reference side 2101. The angle between the line connecting the center point of the main body 21 of each lamp bead 20 in the horizontal row and the center point A of the lamp board 10 and the reference side 2101 of the main body 21 of the lamp bead 20 is the reference angle α, and the angle between the line connecting the center point of the main body 21 of each lamp bead 20 in the vertical row and the center point A of the lamp board 10 and the reference side 2101 of the main body 21 of the lamp bead 20 is the reference angle α.

[0049] For the camera flat panel light 100 of this embodiment, in the final state, the reference angle α formed by all the lamp beads 20 on the light board 10 is the same.

[0050] Taking the two columns of lamp beads 20 in the camera flat panel light 100 shown in Figure 1 as an example, the camera flat panel light 100 includes four horizontal columns and four vertical columns of lamp beads 20. The four lamp beads 20 on the horizontal column close to the first side 11 of the light board 10 are lamp bead No. 1 2011, lamp bead No. 2 2012, lamp bead No. 3 2013 and lamp bead No. 4 2014, and the four lamp beads 20 on the vertical column close to the second side 12 of the light board 10 are lamp bead No. 1 2011, lamp bead No. 2-2 2022, lamp bead No. 3-3 2023 and lamp bead No. 4-4 2024.

[0051] In the final state, the reference edge 2101 of lamp bead No. 1 2011 is its second main body edge 212, the reference edge 2101 of lamp bead No. 2 2012 is its second main body edge 212, the reference edge 2101 of lamp bead No. 3 2013 is its second main body edge 212, and the reference edge 2101 of lamp bead No. 4 2014 is its second main body edge 212. The reference edge 2101 of lamp bead No. 1 2011 is its second main body edge 212, the reference edge 2101 of lamp bead No. 2-2 2022 is its second main body edge 212, the reference edge 2101 of lamp bead No. 3-3 2023 is its second main body edge 212, and the reference edge 2101 of lamp bead No. 4-4 2024 is its second main body edge 212.

[0052] The angle between the line connecting the center point of the main body 21 of lamp bead No. 1 2011 and the center point of the lamp board 10 and the reference side 2101 of lamp bead No. 1, the angle between the line connecting the center point of the main body 21 of lamp bead No. 2012 and the center point of the lamp board 10 and the reference side 2101 of lamp bead No. 2, the angle between the line connecting the center point of the main body 21 of lamp bead No. 3 2013 and the center point of the lamp board 10 and the reference side 2101 of lamp bead No. 3, and the angle between the line connecting the center point of the main body 21 of lamp bead No. 4 2014 and the center point of the lamp board 10 and the reference side 2101 of lamp bead No. 4 are all 90°.

[0053] The angles between the line connecting the center point of the main body 21 of lamp bead 2011 and the center point of the lamp board 10 and the reference side 2101 of lamp bead 2011, the angle between the line connecting the center point of the main body 21 of lamp bead 2022 and the center point of the lamp board 10 and the reference side 2101 of lamp bead 2022, the angle between the line connecting the center point of the main body 21 of lamp bead 2023 and the center point of the lamp board 10 and the reference side 2101 of lamp bead 2023, and the angle between the line connecting the center point of the main body 21 of lamp bead 2024 and the center point of the lamp board 10 and the reference side 2101 of lamp bead 2024 are all 90°. That is, the reference angle α formed by all lamp beads 20 in this embodiment is 90°.

[0054] In other examples of this embodiment, the size of the reference angle α can also be 60°, 75°, 80°, etc., as long as it can be ensured that the size of the reference angle α formed by all lamp beads 20 located on the lamp board 10 is the same and not greater than 90°.

[0055] In the final state, all rotated lamp beads 20 are arranged symmetrically about the center point A of the light panel 10. This arrangement, combined with the fact that the chips 22 have multiple colors and are arranged symmetrically on the main body 21, can evenly mix the light emitted by the chips 22 of different colors, thereby reducing the difference in the superposition of different colors of light, making the overall color of the camera flat panel light 100 more uniform, and effectively improving the photography and videography effects.

[0056] In this embodiment, the lamp beads 20 are configured to rotate clockwise at angles ranging from 15° to 90° around the center of the main body 21. Some of the lamp beads 20 may rotate at the same angle, such as 15° clockwise, while others may rotate at the same angle, such as 30° clockwise, and still others may rotate at the same angle, such as 60° clockwise.

[0057] The direction and angle of rotation of the lamp beads 20 around the center point of the main body 21 are not single, as long as it can be ensured that all the lamp beads 20 in the final state can be centrally symmetrical about the center point A of the lamp board 10.

[0058] For the camera flat panel light of the present application, multiple lamp beads are arranged in an array on the light board. Each of the lamp beads includes a main body and a plurality of chips arranged on the main body. The plurality of chips can be divided into multiple groups according to the different luminous colors of their own. The luminous colors of the chips in each group are the same, and the plurality of chips are arranged in a centrally symmetrical manner on the main body. On the light board, the reference angles formed by all the lamp beads are the same in size. This arrangement enables all the lamp beads to be arranged in a centrally symmetrical manner with respect to the center point of the light board. Combined with the arrangement that multiple groups of chips have multiple different colors and the plurality of chips are arranged in a centrally symmetrical manner on the main body, the light emitted by the chips of multiple colors on the light board can be evenly mixed to reduce the difference after the superposition of light of different colors, making the overall color of the camera flat panel light more uniform, thereby effectively improving the effect of photography and videography.

[0059] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
