Description

Technical Field

[0001] This utility model relates to the field of multi-color LED lamp beads technology, specifically a regular polygonal 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.

[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 a regular polygonal microcrystalline plate, including a substrate 1, which is 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 is made of PMMA plastic.

[0021] One side of the substrate 1 has a regular polygonal recess 102. The bottom wall of the regular polygonal recess 102 is provided with a microstructure 103, which makes the bottom wall of the regular polygonal recess 102 uneven. The microstructure 103 is a recess structure relative to the bottom wall of the regular polygonal recess 102. Preferably, the cross-sectional shape of the microstructure 103 is arc-shaped. The regular polygonal recesses 102 are spaced apart along the length and width directions of the substrate 1, and the regular polygonal recesses 102 spaced apart along the width direction of the substrate 1 are staggered. Therefore, when light emitted by multiple color light-emitting chips passes through the microcrystalline plate, the light will be refracted at different angles on the complex surface, thus achieving sufficient reflection and refraction on the microcrystalline plate. This is beneficial for achieving uniform mixing of multiple primary colors and avoiding color separation. Moreover, the regular polygonal recesses 102 arranged at intervals along the width direction of the substrate 1 are staggered, which is beneficial for light to be refracted at different angles on adjacent regular polygonal recesses 102. This is beneficial for uniform mixing of light transmitted from adjacent regular polygonal recesses 102, further facilitating the occurrence of color separation.

[0022] Optionally, the regular polygonal recess 102 can be a regular square, a regular pentagon, or a regular hexagon; preferably, the regular polygonal recess 102 is a regular hexagon.

[0023] Preferably, the thickness of the substrate 1 is 2-3 mm.

[0024] Preferably, a lens mechanism 101 is provided on the other side of the substrate 1. The lens mechanism 101 includes a first ball head 1011 and a second ball head 1012, which are spaced apart along the length and width directions of the substrate 1. Therefore, the lens mechanism 101 makes the surface of the substrate 1 have an uneven shape. When the light emitted by the light-emitting chips of various colors passes through the microcrystalline plate, the light will be refracted at different angles on the complex surface, thereby achieving sufficient reflection and refraction on the lens mechanism 101. This is beneficial for achieving uniform mixing of multiple primary colors and avoiding 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; in this way, it is beneficial for light to be refracted at different angles on adjacent lens mechanisms 101, thereby facilitating the uniform mixing of light transmitted from adjacent lens mechanisms 101, and further facilitating the occurrence of color separation phenomenon.

[0027] Example 2 Please see Figures 5-7 This utility model also provides a lamp, including a regular polygonal microcrystalline plate as described in Embodiment 1 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 regular polygonal 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 polygonal microcrystalline plate is installed on the lamp housing 3, preferably, the lens structure 101 on the polygonal microcrystalline plate is located on the side of the substrate 1 away from the multi-color LED beads 5, and the regular polygonal recess 101 on the polygonal microcrystalline plate 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 regular polygonal recess 102, so that the light transmitted from the regular polygonal recess 102 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 also 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 a regular polygonal microcrystalline plate. By creating regular polygonal recesses 102 on one side of the substrate 1, and distributing these recesses at intervals along the length and width of the substrate 1, and by providing microstructures 103 on the bottom walls of the recesses 102, the surface of the substrate 1 exhibits an uneven texture. This allows light emitted by multiple color light-emitting chips to be refracted at different angles on the complex surface, thus achieving sufficient reflection and refraction on the microcrystalline plate. Furthermore, lens structures 101 are provided on the other side of the substrate 1, also distributed at intervals along the length and width of the substrate 1, making the surface of the substrate 1 also uneven. This allows light emitted by multiple color light-emitting chips to be refracted at different angles on the complex surface, thereby facilitating uniform mixing of multiple primary colors and avoiding color separation. In addition, the regular polygonal microcrystalline plate adopts a single transparent plate design, which can effectively mix the light emitted by the numerous LEDs integrated on the lamp board 4, thereby achieving an ideal light mixing effect.
