Description

Technical Field

[0001] The utility model belongs to the technical field of aggregating and diffusing LED wick light sources, and in particular relates to a device for aggregating and diffusing LED wick point light sources. Background Art

[0002] LED is a semiconductor device that can directly convert electrical energy into light energy. It has the advantages of high efficiency, long life and environmental protection. It emits light through the recombination of electrons and holes. Different semiconductor materials will produce different colors of light. LED wick light source has become an important technology in the field of lighting due to its high efficiency and environmental protection characteristics. It is widely used in various lighting equipment and backlight displays. With the continuous development and innovation of technology, the cost of LED wick light source has gradually decreased, and the performance has been continuously improved, making LED lighting more and more widely used.

[0003] In the prior art, the LED lamp core generates a point light source when in use. In some cases, the point light source is not delicate enough in appearance, and a device is needed to diffuse the point light source to make it look like a surface light source.

[0004] A Chinese invention patent (application number 2020111246000, authorization announcement number CN112467018B, authorization announcement date 2021.10.15) discloses a mini-LED / micro-LED surface light source and a manufacturing method thereof. The LED surface light source includes a surface light source circuit board, a metal reflective layer and an LED chip, ... The metal reflective layer is formed on the pad array to form an identification point; the disadvantage of this patent is that the LED point light sources one after another are not aesthetically pleasing. The pattern panel alone can make it beautiful. Its structure requires the use of multiple accessories, and the unit price of the product material cost will increase, but this can be solved with an injection molded product, which can save costs and reduce the number of LEDs to save costs.

[0005] The Chinese utility model patent (application number 2014200207074, authorization announcement number CN203671338U, authorization announcement date 20214.06.25) discloses an LED three-dimensional surface light source, which includes an LED wick strip, a heat dissipation bracket, and a light guide plate. A light guide point is set on one side of the light guide plate, and the side opposite to the light guide point is the light-emitting surface of the light guide plate. A three-dimensional pattern is set on the light-emitting surface of the light guide plate. The disadvantage of this patent is that its structure requires the use of multiple accessories, and the unit price of product material costs will increase.

[0006] Therefore, there is a need in the market to develop an LED point light source that is not aesthetically pleasing on its own, but can be made beautiful with just this pattern panel, which can eliminate glare on the LED and convert the point light source into a surface light source with just one pattern panel - all other existing structures incorporate a dual pattern structure and other sheet papers (prism sheet, diffusion sheet).

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 - 7 , the present invention provides the following technical solutions:

[0036] A device for polymerizing and diffusing the point light source of an LED lamp core, comprising: a PCB board 3, and at least one or more LED lamp cores 4 are fixed on at least one surface of the PCB board 3; in Figure 4 In the shown embodiment, seven LED lamp cores 4 are provided on the upper half of the PCB board 3. A polymerization and diffusion cover is also provided on the PCB board 3, and the polymerization and diffusion cover is connected to the front or back of the PCB board 3. The polymerization and diffusion cover is made of a light-transmitting or semi-light-transmitting material, and the distance between the LED lamp core 4 and the diffusion plate has different effects.

[0037] As Figure 3 shown, the upper part of the device for polymerizing and diffusing the point light source of the LED lamp core includes a first polymerization and diffusion cover 1 and a second polymerization and diffusion cover 2. The structures of the first polymerization and diffusion cover 1 and the second polymerization and diffusion cover 2 are similar, one side is a smooth surface, and the other side is a prismatic surface 13 or 23, and the prismatic surface 13 or 23 faces the LED lamp core 4. When the prismatic surface 13 or 23 faces the LED lamp core 4, the effect of diffusing the light source is better.

[0038] In another embodiment, the prism surface 13 or 23 is a concave-convex pattern. By using this solution, when the LED chip is powered on, it generates a point light source. The point light source irradiates on the surface of the prism surface, and after being reflected by the prism surface, the point light source forms a surface-like light source. When the LED chip is in use, its appearance is more delicate and soft, preventing glare, and the formed surface light source is more beautiful.

[0039] As Figures 3 - 7 shown, the lower part of the device for aggregating and diffusing the point light source of the LED chip also includes a first aggregation and diffusion cover 1 and a second aggregation and diffusion cover 2. The structures of the first aggregation and diffusion cover 1 and the second aggregation and diffusion cover 2 are similar. One side is a smooth surface, and the other side is a prism surface 13 or 23. The prism surface 13 or 23 faces away from the LED chip 4. In order to improve the light aggregation and diffusion effect of the prism surface 13 or 23, a first protective cover 15 and a second protective cover 25 are respectively provided on the prism surface 13 or 23. The first protective cover 15 and the second protective cover 25 are respectively integrated with the first aggregation and diffusion cover 1 and the second aggregation and diffusion cover 2, that is: the first protective cover 15 and the first aggregation and diffusion cover 1 are an integrally formed structure, and the first protective cover 25 and the first aggregation and diffusion cover 2 are an integrally formed structure; the first protective cover 15 and the second protective cover 25 are buckled together. The first aggregation and diffusion cover 1 and the second aggregation and diffusion cover 2 form the outer shell part of the PCB board 3. The PCB board 3 is located inside the first aggregation and diffusion cover 1 and the second aggregation and diffusion cover 2. There are multiple LED chips 4, and the multiple LED chips 4 are respectively fixedly connected to two surfaces of the PCB board 3. The LED chips 4 on the two surfaces of the PCB board 3 respectively irradiate into the first aggregation and diffusion cover 1 and the second aggregation and diffusion cover 2. The prism surfaces 131 and 231 play a role in diffusing the point light source. When the LED chip 4 is powered on, it emits light to generate a point light source. The point light source is reflected by the prism surfaces 131 and 231 to form a surface-like light source. The LED chip 4 is located inside the first aggregation and diffusion cover 1 and the second aggregation and diffusion cover 2. The prism surfaces 131 and 231 and the flat plate inside the first aggregation and diffusion cover 1 and the second aggregation and diffusion cover 2 play a role in aggregating and diffusing the point light source of the LED chip.

[0040] As Figures 4 - 7 shown, the prism surface of the aggregation and diffusion cover is a geometric structure, and the geometric structure is a surface formed by connecting multiple concave geometric shapes on one surface; or it can be said that the prism surface of the aggregation and diffusion cover is a surface formed by connecting multiple convex geometric shapes on one surface.

[0041] At least one or more than one LED chip (4) is / are respectively fixed on the front and back surfaces of the PCB board 3; the first aggregation and diffusion cover 1 and the second aggregation and diffusion cover 2 are respectively fixedly connected or movably connected to the PCB board 3.

[0042] The surface of the first polymerization and diffusion cover 1 is provided with fasteners 11 and slots 12, and the surface of the second polymerization and diffusion cover 2 is provided with fasteners 21 and slots 22. The fasteners 11 and slots 12 respectively cooperate with the slots 22 and fasteners 21 to fix the first polymerization and diffusion cover 1 and the second polymerization and diffusion cover 2 together. In this embodiment: when the first polymerization and diffusion cover 1 and the second polymerization and diffusion cover 2 are connected, the fasteners slide into the slots, and at this time, the first polymerization and diffusion cover 1 and the second polymerization and diffusion cover 2 cannot be separated, completing their fixation. The first polymerization and diffusion cover 1 and the second polymerization and diffusion cover 2 form a closed whole in the circumferential direction, and the LED lamp cores 4 installed on the PCB board 3 are completely covered by the closed outer shell of the first polymerization and diffusion cover 1 and the second polymerization and diffusion cover 2. In this embodiment, for the LED lamp core matrix 4, due to the polymerization and diffusion effects of the prism surfaces 13 and 23 on the light of the LED lamp core matrix 4, in addition to generating soft surface light at the LED lamp core matrix 4, when viewed from the side, the side can also emit light, that is, the light of the closed outer shell emits light 360 degrees. Without this pattern outer shell composed of the first polymerization and diffusion cover 1 and the second polymerization and diffusion cover 2, the light cannot be emitted from the side.

[0043] In another embodiment, the prism surface is composed of a plurality of prism lenses connected end to end, and the prism lenses form a certain angle for diffusing point light sources. The prism surface is composed of a plurality of prism lenses connected end to end, and the prism lenses form a certain angle. When the point light source generated by the illumination of the LED lamp core 4 shines on the reflection surface of the prism lens, after being reflected by the prism surface, the light is reflected in different directions to form a light source similar to a surface. For details, please refer to Figures 1 - 4 , the brightness of the prism surface 13 in the first polymerization and diffusion cover 1 for diffusing the LED lamp core 4 is higher than that of the prism surface 23 in the second polymerization and diffusion cover 2 for diffusing the LED lamp core 4. The inner part of the second polymerization and diffusion cover 2 is a flat plate, and the brightness generated by its reflection of the point light source is lower than the brightness of the prism surface 131 and the prism surface 231 reflecting the light source. The first polymerization and diffusion cover 1 is set as the front, and the second polymerization and diffusion cover 2 is set as the back. When the first polymerization and diffusion cover 1 is the front and the second polymerization and diffusion cover 2 is the back, when rotating the first polymerization and diffusion cover 1 and the second polymerization and diffusion cover 2, light sources with different brightnesses can be selected according to the usage needs.

[0044] In another embodiment, the polymerization and diffusion cover can be designed into a structure with adjustable direction and position. This kind of structure with adjustable direction and position belongs to the scope of the prior art and will not be introduced in detail here. When the polymerization and diffusion cover can be designed into a structure with adjustable direction and position, when adjusting the polymerization and diffusion cover, the prism surface of the polymerization and diffusion cover is adjusted at the same time, and the degree of polymerization and diffusion of the light of the LED lamp core 4 can be adjusted according to the direction and position of the prism surface. When the pattern part faces the LED, the farther away from the LED, the more the light diffuses.

[0045] The device for aggregating and diffusing the point light source of the LED lamp core of the present utility model reflects the point light source generated by the LED lamp core 4 through the prism surface 131 and the prism surface 231, so that the reflected point light source is similar to a surface light source.
