DETAILED DESCRIPTION

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solutions of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0029] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0030] Please refer to Figures 1 to 7, which show a lamp 100 provided by the present invention. The lamp 100 is a direct-type surface light source. The lamp 100 has rich color changes and flexible brightness control capabilities, and can provide a more natural and comfortable lighting effect.

[0031] The lamp 100 includes a light source module 1 and a lamp assembly 2 . The light source module 1 is disposed in a receiving space 24 of the lamp assembly 2 .

[0032] The light source module 1 includes a light source board 11 and at least two groups of light source assemblies 12 arranged on the light source board 11, and the light-emitting units 121 in each group of light source assemblies 12 are arranged in a similar shape, and the light-emitting units 121 in the light source assembly 12 are arranged equidistantly, and the arrangement form can be a straight line, a curve, or a ring. Due to the similar shapes of the light source assemblies 12, they can be arranged equidistantly along one direction, or arranged equidistantly from the inside to the outside in rings of different sizes and similar shapes. The arrangement of similar shapes of each group of light source assemblies 12 ensures the uniformity of light emission of the lamp 100. Through this similar shape arrangement design, the size and weight of the entire light source module 1 can be reduced while ensuring a sufficient lighting range, which is conducive to saving space and cost.

[0033] Each group of light source assemblies 12 includes multiple light-emitting units 121 with at least two different colors. Within the same group of light source assemblies 12, at least two light-emitting units 121 with different colors are arranged in a circular pattern on the light source board 11 to prevent adjacent light-emitting units 121 in the same group of light source assemblies 12 from having the same color, thereby causing the appearance of bright lines and affecting the visual effect.

[0034] Furthermore, the color of the light emitting units 121 on any group of light source assemblies 12 is also different from the color of the light emitting units 121 closest to it on the adjacent group.

[0035] 4 and 5 , in this embodiment, the light source board 11 is rectangular, and the light emitting units 121 of each group of light source assemblies 12 form a square shape, so that multiple groups of light source assemblies 12 are arranged in a similar U-shaped pattern on the light source board. The light source assemblies 12 are of different sizes and similar shapes and are arranged on the light source board 11 at equal intervals from the inside to the outside. Each group of light source assemblies 12 includes light emitting units 121 of four different colors. Within the same group of light source assemblies 12, the light emitting units 121 of four different colors are arranged in a circular pattern on the light source board 11. The light emitting units 121 on any group of light source assemblies 12 have different colors from the light emitting units 121 closest to them on the adjacent group. The U-shaped arrangement can also improve the compactness and aesthetics of the entire light source module 1.

[0036] In other embodiments, the light emitting units 121 of each light source assembly 12 may be arranged in a straight line, so that the entire assembly is arranged in a matrix. The light emitting units 121 in each light source assembly 12 may also be arranged in a curve, which is not limited in the present invention.

[0037] Optionally, the four different colors of light-emitting units 121 are: red light-emitting unit, blue light-emitting unit, yellow light-emitting unit, and green light-emitting unit. These four colors are the easiest to identify and provide a more colorful visual effect. In other embodiments, the colors of the light-emitting units 121 can also be other colors.

[0038] The light source board 11 has four corners. The density of the light emitting units 121 at the four corners is greater than the density of the light emitting units 121 at other positions on the light source board 11, which solves the problem of low brightness in the four corners and makes the four corners brighter when the lamp 100 is illuminated, thereby enhancing the lighting effect.

[0039] Specifically, each corner includes four light-emitting units 121 of different colors. These light-emitting units 121 are arranged in the gaps between two adjacent groups of light source assemblies 12. The four light-emitting units 121 are arranged in a circular pattern within the gaps, and the number of light-emitting units 121 in each corner is the same. This arrangement makes the light emitted by the lamp 100 more uniform.

[0040] In this embodiment, the light source panel 11 includes a symmetrically arranged first portion 111 and second portion 112, with a plurality of light-emitting units 121 arranged in a mirror-image arrangement on the first portion 111 and the second portion 112. This arrangement reduces the packaging size of the lamp 100, facilitates mass production, and saves time and money.

[0041] In another embodiment, the light source board 11 can also be configured into four symmetrical sections, with the multiple light-emitting units 121 arranged in a mirrored arrangement along the centerline of the light source board 11 in the longitudinal direction, and also in a mirrored arrangement along the centerline of the light source board in the width direction. In other words, regardless of how many sections the light source board 11 is divided into, the arrangement of the light-emitting units 121 on each section of the light source board 11 is exactly the same, further enhancing the consistency of the lighting effect while reducing costs.

[0042] In another embodiment of the present invention, the light source board 11 is circular and has a diameter direction. The light-emitting units 121 in each group of light source assemblies 12 form a ring, so that all light source assemblies 12 are arranged equidistantly from the inside to the outside in rings of different sizes and similar shapes. Each group of light source assemblies 12 includes light-emitting units 121 of four different colors. Within the same group of light source assemblies 12, the light-emitting units 121 of four different colors are arranged in a circular pattern on the light source board 11. In the diameter direction, the light-emitting units 121 on any group of light source assemblies 12 have different colors from the light-emitting units 121 closest to them in the adjacent group, thereby preventing the appearance of bright lines. The present invention does not limit the shape of the light source board 11.

[0043] Each color of the light-emitting unit 121 can be controlled independently, and when each color of the light-emitting unit 121 is individually illuminated, the brightness distribution of the lamp 100 is consistent. When the light-emitting unit 121 of one color is illuminated and the light-emitting units 121 of the other three colors are not illuminated, the brightness distribution is consistent, with a uniformity performance of 85%.

[0044] The distribution density of the light-emitting units 121 of the four colors is consistent, the lighting effect is very uniform, and the display effect is very consistent. On this basis, when dimming and color adjustment are achieved, the uniformity distribution of the surface light source of the entire lamp 100 is always maintained unchanged.

[0045] The lamp 100 can light up all or part of the light emitting units 121. Through this setting, all or part of the light emitting units 121 can be selected to light up according to actual needs to achieve different lighting effects, providing users with more control options.

[0046] Specifically, when the lamp 100 is installed in a large space with high lighting requirements, all the light-emitting units 121 of the lamp 100 can be controlled to light up, presenting an excellent lighting effect. When the lamp 100 is located in a KTV, the four-color light-emitting units 121 of the lamp 100 can be controlled to flash alternately to create a sense of atmosphere.

[0047] Furthermore, the red light emitting unit 121 can be set to be on, while the light emitting units 121 of other colors are off or flashing, or the light emitting units 121 of some colors are lit. The lighting state of the light emitting units 121 of different colors is determined according to the specific scene and usage requirements, and the present invention is not limited to this.

[0048] Preferably, the light source module 1 further includes a lens 13, which is provided in a one-to-one correspondence with the light-emitting unit 121, or alternatively, the lens 13 is provided in a one-to-one correspondence with the light source assembly 12. By providing the lens 13, the light emitted by the light-emitting unit 121 can be converged or diffused, further adjusting the lighting effect and light distribution. Furthermore, the lens 13 can also protect the light-emitting unit 121, thereby improving the reliability and stability of the entire light source module 1.

[0049] In other embodiments, the lens 13 may not be used, in which case the light mixing distance should be increased accordingly.

[0050] The lamp assembly 2 includes a housing 21 , a frame 22 and a diffusion plate 23 .

[0051] The housing 21 and the frame 22 enclose a receiving space 24 , and the light source module 1 is disposed in the receiving space 24 , thereby effectively protecting the light source module 1 and achieving a dustproof effect.

[0052] The height of the frame 22 is greater than the height of the receiving space 24 , making the lamp 100 neater and more beautiful, and the lamp body is thinner. Combined with the direct-down lamp body design, it also effectively prevents external dust and debris from entering the interior of the lamp 100 .

[0053] The lamp 100 of the present invention has a simple structure, is easy to manufacture, and provides a variety of color lighting effects. This not only enhances the visual effect of the lighting but also provides users with more control options and flexibility. This lamp 100 can be widely used in home, commercial, and industrial applications, such as home decoration, parties, store displays, billboards, and other occasions.

[0054] In summary, the light source panel 11 of the lamp 100 of the present invention is provided with at least two groups of light source assemblies 12, each group of light source assemblies 12 includes a plurality of light-emitting units 121 having at least two different colors, the light-emitting units 121 in each group of light source assemblies 12 are of the same color and arranged in a similar shape, the light-emitting units 121 of at least two different colors are arranged in a circular pattern, and the light-emitting units 121 of each color can be individually controlled in brightness and on and off, thereby achieving a surface light source with very uniform colors. The diversified settings of the shape and arrangement of the light source module 1 can be customized and produced according to actual needs to meet the lighting needs of different fields and application scenarios.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
