Description

Technical Field

[0001] This utility model relates to the field of multi-color LED lamp beads technology, specifically an M-type microcrystalline plate and lamp. Background Technology

[0002] LED lights are lighting fixtures that use LED light-emitting chips as the light source. LED lights have many advantages, including high efficiency, long lifespan, low energy consumption, and environmental friendliness. Currently, the common LED lighting technology uses blue light + phosphor, which makes it difficult to coordinate luminous efficacy and quality, and has a high lumen efficiency. After subsequent improvements, phosphorless multi-color LED lighting has been gradually adopted, which uses multiple colors such as red, yellow, green, and blue light to directly synthesize white light, without the need for phosphors to emit light.

[0003] For multi-color LED chips, because they mix the light emitted by multiple color chips, uneven color mixing occurs throughout the entire LED chip, resulting in noticeable color separation. Currently, to address this uneven mixing issue, a common method is to assign a corresponding bulb to each LED or group of LEDs. Each bulb can cover one or more LEDs, allowing for thorough mixing of light emitted by different colors through reflection and refraction. However, since a single bulb can only cover a small number of LEDs, when a large number of LEDs are integrated onto the LED board, achieving an ideal overall mixing effect becomes difficult. Utility Model Content

[0004] The purpose of this utility model is to improve and innovate upon the shortcomings and problems existing in the background technology, and to provide an M-type microcrystalline plate and lamp.

[0005] According to a first aspect of the present invention, an M-shaped microcrystalline plate is provided, comprising a substrate, wherein a second lens structure is provided on one side of the substrate, and two adjacent second lens structures are M-shaped such that the second lens structure has a peak and a valley, and the second lens structures are spaced apart along the length and width directions of the substrate.

[0006] A further approach is to stagger the second lens structures spaced apart along the width direction of the substrate, so that the peaks and valleys of adjacent second lens structures correspond to each other.

[0007] A further embodiment is that the second lens structure is a triangular prism, which extends along the width direction of the substrate, and the triangular prisms are spaced apart and staggered from each other along the width direction of the substrate.

[0008] A further embodiment is that a first lens structure is provided on the other side of the substrate. The first lens structure includes a first ball head and a second ball head. The first ball head and the second ball head are both spaced apart along the length and width directions of the substrate, and the first ball head and the second ball head are staggered with each other along the length and width directions of the substrate.

[0009] A further approach is to have the first and second ball heads have different diameters.

[0010] A further design is that the diameter of the first ball head is larger than the diameter of the second ball head, and the middle of the first ball head is provided with a hollowed-out portion.

[0011] A further option is that the hollowed-out portion is conical in shape, and the cross-section of the hollowed-out portion is triangular.

[0012] A further embodiment is that the substrate, the first lens structure, and the second lens structure are made of transparent PS plastic, PC plastic, or PMMA plastic.

[0018] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Example 1 Please see Figures 1-4This utility model provides an M-type microcrystalline plate, including a substrate 1. A second lens structure 102 is disposed on one side of the substrate 1, and a first lens structure 101 is disposed on the other side of the substrate 1. The substrate 1, the first lens structure 101, and the second lens structure 102 are all made of transparent PS plastic, PC plastic, or PMMA plastic. PS plastic is polystyrene, a colorless and transparent thermoplastic; PC plastic is polycarbonate, a colorless, transparent, high-strength, and heat-resistant plastic; PMMA plastic generally refers to plexiglass, also called acrylic, which has good transparency. Preferably, the substrate 1, the first lens structure 101, and the second lens structure 102 are all made of PMMA plastic.

[0021] The second lens structure 102 is triangular prism-shaped, giving it peaks and valleys. The peaks correspond to the highest points of the triangular prisms, and the valleys correspond to the lowest points. Adjacent triangular prisms are joined together to form an approximate M-shaped profile. The second lens structure 102 is spaced along the length and width of the substrate 1, covering the entire surface of the substrate 1. This gives the substrate 1 an uneven surface. When light emitted from multiple color light-emitting chips passes through the microcrystalline plate, the light is refracted at different angles on the complex surface, achieving sufficient reflection and refraction on the second lens structure 102. This facilitates uniform mixing of multiple primary colors and avoids color separation.

[0022] Preferably, the second lens structures 102 are staggered along the width direction of the substrate 1, so that the peaks and valleys of adjacent second lens structures 102 correspond to each other. This facilitates the refraction of light at different angles on adjacent second lens structures 102, thereby promoting uniform mixing of light transmitted from adjacent second lens structures 102 and further promoting the occurrence of color separation.

[0023] Preferably, the thickness of the substrate 1 is 2-3 mm; and the height of the second lens structure 102 is 0.4-0.6 mm.

[0024] Preferably, the first lens structure 101 includes a first ball head 1011 and a second ball head 1012, both of which are spaced apart along the length and width directions of the substrate 1. Therefore, the first lens structure 101 makes the surface of the substrate 1 exhibit an uneven texture; when light emitted from multiple color light-emitting chips passes through the microcrystalline plate, the light is refracted at different angles on the complex surface, thus achieving sufficient reflection and refraction on the first lens structure 101. This facilitates uniform mixing of multiple primary colors and avoids color separation.

[0025] Preferably, the diameter of the first spherical head 1011 is larger than the diameter of the second spherical head 1012, and a hollow portion 10111 is provided in the middle of the first spherical head 1011. The hollow portion 10111 is conical in shape. This hollow design can effectively reduce the material thickness in the central region of the first spherical head 1011, avoiding excessive absorption and scattering loss of light emitted by the multi-primary-color light-emitting chip when it passes through the first spherical head 1011 due to excessively thick medium. Therefore, by creating the hollow portion 10111, the overall light efficiency can be improved.

[0026] Preferably, the first ball head 1011 and the second ball head 1012 are staggered along the length and width directions of the substrate 1, and the diameters of the first ball head 1011 and the second ball head 1012 are different; thus, it is beneficial for light to be refracted at different angles on adjacent first lens structures 101, which is beneficial for the uniform mixing of light transmitted from adjacent first lens structures 101, and further beneficial for the occurrence of color separation phenomenon.

[0027] Example 2 Please see Figures 5-7 This utility model also provides a lamp, including an M-shaped microcrystalline plate as described in Embodiments 1 and 2 and a lamp housing 3. The lamp housing 3 has an opening at the top and a lamp plate 4 is installed on the bottom wall of the lamp housing 3. Multi-color LED beads 5 are installed on the lamp plate 4, and the multi-color LED beads 5 are spaced apart along the width and length directions of the lamp plate 4. The multi-color LED beads 5 include light-emitting chips of four colors: red, yellow, green, and blue. The M-shaped microcrystalline plate is installed at the opening of the lamp housing 3 through a face frame 2.

[0028] It should be noted that when the M-shaped microcrystalline board is installed on the lamp housing 3, preferably, the first lens structure 101 on the M-shaped microcrystalline board is located on the side of the substrate 1 away from the multi-color LED beads 5, and the second lens structure 102 on the M-shaped microcrystalline board is located on the side of the substrate 1 close to the multi-color LED beads 5.

[0029] Optionally, the face frame 2 is provided with a limiting groove 201 adapted to the substrate 1. A through groove 202 is provided in the middle of the limiting groove 201. The through groove 202 corresponds to the first lens structure 101 and the second lens structure 102, so that the light passing through the second lens structure 102 and the first lens structure 101 will not be blocked by the face frame 2. The substrate 1 is disposed between the face frame 2 and the lamp housing 3. The face frame 2 is mounted on the lamp housing 3, thereby fixing the microcrystalline plate on the lamp housing 3.

[0030] Optionally, corresponding through holes are provided on the bottom walls of the lamp panel 4 and the lamp housing 3. After aligning the through holes of the lamp panel 4 and the lamp housing 3 one by one, nylon rivets are pressed into the respective holes to quickly complete the riveting operation between the lamp panel 4 and the lamp housing 3. Corresponding through holes are provided on the upper end of the lamp housing 3 and the face frame 2, and corresponding semi-circular arc through grooves are provided on the edge of the base plate 1. After aligning the through holes on the upper end of the lamp housing 3 and the through holes of the face frame 2 one by one, nylon rivets are pressed into the respective holes to quickly complete the riveting operation between the face frame 2 and the lamp housing 3.

[0031] In summary, this utility model provides an M-shaped microcrystalline plate. By setting a first lens structure 101 and a second lens structure 102 on the substrate 1, these lens structures are spaced apart along the length and width of the substrate 1, making the surface of the substrate 1 exhibit an uneven shape. This allows the light emitted by the multi-color light-emitting chips to be refracted at different angles on the complex surface, thereby achieving sufficient reflection and refraction on the lens structure. This is beneficial for achieving uniform mixing of multi-primary-color light and avoiding color separation. In addition, the M-shaped microcrystalline plate adopts a design of a single transparent plate, which can effectively mix the light emitted by the large number of multi-primary-color LED beads 5 integrated on the lamp board 4, thereby achieving an ideal light mixing effect.
