Description

Technical Field

[0001] The present invention belongs to the technical field of LED lamps, and in particular relates to a detachable light-changing high-light-efficiency anti-glare LED lamp and a realization method thereof. Background Art

[0002] Currently, many anti-glare LED products on the market offer non-removable anti-glare features. These features are overly simple, fail to address LED spotting, and feature wide angles, resulting in low optical efficiency. There is a need for an LED lamp with a removable structure, improved anti-glare and spotting effects, and high overall lighting efficiency. This design would require a simple structure, easy assembly and disassembly, and a one-time mold investment. Customizable honeycomb covers, prisms, or filters could be designed to meet specific application needs. Consumers can choose between these options, offering easy assembly and disassembly, a wide range of applications, and sustainable development.

[0003] The current technology has the following shortcomings:

[0004] 1. The anti-glare device cannot be disassembled and cannot adapt to different applications and needs;

[0005] 2. The light spot is uneven, the light is radiant, etc.

[0006] 3. The optical angle is basically around 15 to 25 degrees, and it is impossible to achieve around 10 degrees;

[0012] Further in the present invention, the connecting cover is provided with a buckle corresponding to the card slot, and the connecting cover and the heat dissipation housing are snap-fitted through the buckle and the card slot.

[0013] Further in the present invention, the connecting cover is provided with a light outlet.

[0014] Further in the present invention, the upper surface and the circumference of the upper end of the lens are provided with dense triangular prisms, and the circumference of the lower end of the lens is provided with dense scales.

[0015] Further in the present invention, the optical member is a prism, a filter lens or two superimposed polarizing plates.

[0016] Further in the present invention, the polarizing plate is provided with dense and inclined polarizing teeth.

[0017] Further in the present invention, the polarizing teeth on the two superimposed polarizing plates are arranged in the same direction, perpendicular to each other or in the opposite direction.

[0018] Further in the present invention, the method for realizing the detachable variable-light high-light-efficiency anti-glare LED lamp includes the following steps:

[0019] (1) The driving board is clamped inside the connecting seat, the light source board is located above the inside of the heat dissipation housing, and the screw penetrates through the light source board and the heat dissipation housing and is meshed and connected with the connecting seat;

[0020] (2) The lens, the honeycomb cover and the optical member are sequentially superimposed above the heat dissipation housing;

[0021] (3) The connecting cover is snap-fitted with the card slot on the heat dissipation housing through the buckle;

[0022] (4) Limit the lens, the honeycomb cover and the optical member through the connecting cover;

[0023] (5) The optical member is a prism, a filter lens or two superimposed polarizing plates.

[0024] Further in the present invention, for the method for realizing the detachable variable-light high-light-efficiency anti-glare LED lamp, a plurality of card slots are provided on the circumference above the heat dissipation housing; the connecting cover is provided with a buckle corresponding to the card slot, and the connecting cover and the heat dissipation housing are snap-fitted through the buckle and the card slot; the connecting cover is provided with a light outlet; the upper surface and the circumference of the upper end of the lens are provided with dense triangular prisms, and the circumference of the lower end of the lens is provided with dense scales; the polarizing plate is provided with dense and inclined polarizing teeth; the polarizing teeth on the two superimposed polarizing plates are arranged in the same direction, perpendicular to each other or in the opposite direction.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. The connecting cover and the heat dissipation housing of the present invention are connected by snap fits and card slots, which facilitates the disassembly of the connecting cover, thereby facilitating the replacement of optical components, and thus facilitating the magnification of the light angle, the color change of the light spot, or the offset of the light spot;

[0027] 2. The lens of the present invention adopts the Fresnel spectro - superposition method, enabling the light rays of the Lambert - type distributed light source to reach the maximum utilization efficiency. Moreover, on each layer of the Fresnel cup body of the lens, by means of differential segmentation, tiny differential straight - edged square scales are formed. Each scale collimates all the light rays passing through it based on the principle of total internal reflection. All the total - internal - reflection light rays on the Fresnel cup body are integrated and projected onto the light - emitting surface to form a small angle of 10°. There are triangular prisms arranged radially on the light - emitting surface. The light rays passing through the light - emitting surface overlap on the concave clamping surfaces of the triangular prisms, resulting in a soft light spot and enhancing the central light intensity, thus meeting the requirements of high - performance small - angle;

[0028] 3. The honeycomb cover of the present invention is black. When light passes through the black honeycomb cover, stray light such as secondary light spots will be absorbed by the inner walls of each small honeycomb, leaving only the main light spot, achieving the ultimate anti - glare effect. The most obvious feature of the ultimate anti - glare is that the light fades from the center to the edge gradually. The smaller the grid of the honeycomb cover, the more obvious the light - fading effect, and the more concentrated the illumination range of the light, reducing the harm of glare to the human eye;

[0029] 4. The lower surface of the prism of the present invention is a plane, and a long - strip convex bud microstructure is added to the upper surface. The collimated light rays of the LED lamp bead enter through the lower surface of the prism. When the entering light rays pass through the convex bud structure on the upper surface of the prism, the light - ray direction will be changed by the convex bud structure, forming an elongated long - strip light spot on the receiving screen, meeting the customer's requirements for the transformation of the light - spot shape;

[0030] 5. The filter lens of the present invention is a flat circular thin sheet with flat upper and lower surfaces. The filter lens is a colored transparent thin sheet formed by optically transparent PC injection molding with different colored powders added. According to the customer's needs, the light spot of the LED lamp bead will show the corresponding colored light spot on the receiving screen when passing through the filter lens of a certain color;

[0031] 6. The polarizer of the present invention adopts a double - layer superposition mode. Using the principle of optical wedge angle superposition, the polarizer is designed with a fixed angle of a°. Two polarizers with their light - emitting surfaces facing upward are placed in the connecting cover. The polarizer close to the lens is fixed, and the upper - layer polarizer rotates around the Z - axis in the X - Y plane. When the polarization - tooth directions of the two polarizers are the same, the offset angle of the whole - lamp light spot is 2a°; when the polarization - tooth directions of the two polarizers form a 90° angle, the offset angle of the whole - lamp light spot is a°; when the polarization - tooth directions of the two polarizers are opposite, the position of the whole - lamp light spot has no offset; moreover, the two polarizers and the connecting cover are not in a tightly - fitting manner, so that the upper - layer polarizer can be gently rotated without disassembling the connecting cover, achieving the purpose of flexible deflection of the light spot;

[0032] 7. The LED lamp beads of the present invention adopt the KGF fluoride red powder technology. The KGF fluoride powder has much higher excitation efficiency in the red light band compared with the conventional nitride powder. That is to say, under the condition of the same brightness, the color rendering index of the KGF powder LED is higher than that of the conventional nitride powder LED. By mixing fluoride phosphor in a certain proportion, the luminous efficiency of R90 is basically the same as that of the conventional nitride powder R80. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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.

[0052] Embodiment 1

[0053] Please refer to Figure 1-17 , the present invention provides the following technical solutions: A detachable variable-light high-light-efficiency anti-glare LED lamp, including a heat dissipation housing 3, a connection seat 1 is connected below the heat dissipation housing 3, a driving board 2 is arranged inside the connection seat 1, a light source board 4 is arranged inside the heat dissipation housing 3, LED lamp beads 5 are arranged on the light source board 4, a lens 6 is arranged above the heat dissipation housing 3, a honeycomb cover 7 is arranged above the lens 6, an optical component is arranged above the honeycomb cover 7, a connection cover 8 is snap-fitted above the heat dissipation housing 3, and a light outlet 81 is arranged on the connection cover 8.

[0054] Furthermore, four card slots 31 are arranged on the circumference above the heat dissipation housing 3, buckles 82 corresponding to the card slots 31 are arranged on the connection cover 8, and the connection cover 8 and the heat dissipation housing 3 are snap-fitted and connected through the buckles 82 and the card slots 31.

[0055] By adopting the above technical solutions, it is convenient to disassemble the connection cover 8, so as to facilitate the replacement of the optical component, so as to facilitate the magnification of the light angle, the color change of the light spot or the offset of the light spot.

[0056] Furthermore, dense triangular prisms 61 are arranged on the upper surface and the upper circumference of the lens 6, and dense scales 62 are arranged on the lower circumference of the lens 6.

[0057] By adopting the above technical solution, lens 6 uses a Fresnel spectral superposition method to maximize the utilization efficiency of the Lambertian distribution light source. In addition, each layer of the Fresnel cup of lens 6 is formed through differential segmentation to form tiny differential straight-edged square scales 62. Each scale 62 collimates all light passing through it through the principle of total internal reflection. All the totally reflected light on the Fresnel cup is integrated and directed onto the light-emitting surface, forming a small angle of 10°. The light-emitting surface is equipped with radially arranged triangular prisms 61. Light passing through the light-emitting surface overlaps on the concave clamping surface of the triangular prisms 61, resulting in a soft light spot and enhanced central light intensity, thereby achieving high performance at a small angle.

[0058] Furthermore, the optical parts are a prism 9, a filter sheet 10 or two superimposed polarizers 11. After the connecting cover 8 is engaged with the heat dissipation shell 3, a height of 8 mm is left between the connecting cover 8 and the heat dissipation shell 3. The thickness of the honeycomb cover 7, the prism 9 and the filter sheet 10 are all 4 mm, and the thickness of a single polarizer is 2 mm. According to actual needs, the prism 9, the filter sheet 10 or the two superimposed polarizers 11 can be placed above the honeycomb cover 7.

[0059] By adopting the above technical solution, the honeycomb cover 7 is black. When light passes through the black honeycomb cover 7, stray light such as the secondary light spot will be absorbed by the inner wall of each small honeycomb, leaving only the main light spot, achieving an extreme anti-glare effect. The most obvious feature of extreme anti-glare is that the light gradually loses light from the center to the edge. The smaller the grid of the honeycomb cover, the more obvious the light loss effect, the more concentrated the light irradiation range, and reduce the damage of glare to the human eye.

[0060] The lower surface of the prism 9 is flat, and the upper surface is added with a long strip of convex microstructure (the texture of the upper surface can also be designed into other shapes). The collimated light of the LED lamp bead 5 enters through the lower surface of the prism 9. When the entering light passes through the convex structure on the upper surface of the prism 9, the convex structure will change the direction of the light, forming an elongated strip of light spot on the receiving screen, meeting the customer's demand for changing the shape of the light spot;

[0061] The filter sheet 10 is a flat circular sheet with flat top and bottom. The filter sheet 10 is a colored transparent sheet made of optically transparent PC injection molding with different colored toner added. According to customer needs, the light spot of the LED lamp bead 5 will be displayed on the receiving screen according to the color of the filter sheet 10 through which it passes.

[0062] Example 2

[0063] This embodiment differs from the first embodiment in that: further, the polarizer 11 is provided with dense and inclined polarizer teeth, and the polarizer teeth on the two superimposed polarizers 11 are arranged in the same direction, perpendicular to each other, or opposite to each other.

[0064] By adopting the above technical solution, the polarizer 11 adopts a double-layer superposition mode. Using the principle of optical wedge angle superposition, the polarizer 11 is designed with a fixed angle of a°. Two polarizers 11 with their light-emitting surfaces facing upward are placed in the connecting cover 8. The polarizer 11 close to the lens 6 is fixed, and the upper polarizer 11 rotates around the Z-axis in the X-Y plane. When the polarization tooth directions of the two polarizers 11 are the same, the deflection angle of the whole lamp spot is 2a°; when the polarization tooth directions of the two polarizers 11 form a 90° angle, the deflection angle of the whole lamp spot is a°; when the polarization tooth directions of the two polarizers 11 are opposite, the position of the whole lamp spot has no deflection; moreover, the two polarizers 11 and the connecting cover 8 are not in a tightly fitting manner, so that the upper polarizer 11 can be gently rotated without disassembling the connecting cover 8, achieving the purpose of flexible deflection of the light spot.

[0065] Example 3

[0066] The difference between this embodiment and Embodiment 1 is that: the LED lamp beads 5 adopt the KGF fluoride red powder technology. The fluoride powder has a much higher excitation efficiency in the red light band compared with the conventional nitride powder. That is to say, under the same brightness, the color rendering index of the fluoride powder lamp beads is higher than that of the conventional nitride powder lamp beads. By mixing fluoride fluorescent powder in a certain proportion, the light efficiency of R90 is basically the same as that of the conventional nitride powder R80. The conventional high-color-rendering lamp bead solutions on the market all use nitride powder, and the light efficiency of its fluorescent powder solution for R90 is about 15% lower than that for R80. The KGF powder solution can effectively make up for this defect and effectively improve the overall light efficiency of the lamp; the LED lamp beads 5 use the 7070 type produced by a lumen manufacturer.

[0067] As Figure 16 and 17 shown, when comparing with a unified color temperature of 5000K, the light efficiencies of the two types of LEDs are basically the same. The excitation intensity of the KGF powder LED in the red light band is much greater than that of the conventional nitride powder. Under the same light efficiency, the color rendering index of the LED using KGF powder is significantly greater than that of the conventional R80 nitride powder LED.

[0068] Furthermore, the implementation method of the detachable variable-light high-light-efficiency anti-glare LED lamp of the present invention includes the following steps:

[0069] (1). The driving board 2 is stuck inside the connecting seat 1, the light source board 4 is located above the inside of the heat dissipation housing 3, and the screw passes through the light source board 4 and the heat dissipation housing 3 and is meshed with the connecting seat 1 for connection;

[0070] (2). The lens 6, the honeycomb cover 7 and the optical component are sequentially stacked above the heat dissipation housing 3;

[0071] (3). The connecting cover 8 is snap-fitted with the card slot 31 on the heat dissipation housing 3 through the snap 82;

[0072] (4) Limit the lens 6, the honeycomb cover 7 and the optical component through the connecting cover 8;

[0073] (5) The optical component is a prism 9, a filter lens 10 or two mutually superposed polarizing plates 11.

[0074] In summary, the connecting cover 8 of the present invention is snap-fitted to the heat dissipation housing 3 through the snap 82 and the card slot 31, which facilitates the disassembly of the connecting cover 8, thereby facilitating the replacement of the optical components, and thus facilitating the magnification of the light angle, the color change of the light spot, or the offset of the light spot; the lens 6 of the present invention adopts the Fresnel spectroscopic superposition method, so that the light rays of the Lambertian distribution light source can reach the maximum utilization efficiency. Moreover, on each layer of the Fresnel cup body of the lens 6, tiny differential straight-edge square scales 62 are formed by the differential segmentation method. Each scale 62 collimates all the light rays passing through it by the total reflection principle. All the total reflection light rays on the Fresnel cup body are integrated and projected onto the light-emitting surface to form a small angle of 10°. There are triangular prisms 61 arranged radially on the light-emitting surface. The light rays passing through the light-emitting surface overlap on the concave clamping surfaces of the triangular prisms 61, making the light spot soft and enhancing the central light intensity, thus meeting the requirements of high-performance small angles; the honeycomb cover 7 of the present invention is black. When the light passes through the black honeycomb cover 7, stray light such as secondary light spots will be absorbed by the inner walls of each small honeycomb, leaving only the main light spot, achieving the ultimate anti-glare effect. The most obvious feature of the ultimate anti-glare is that the light loses intensity gradually from the center to the edge. The smaller the grid of the honeycomb cover, the more obvious the light loss effect, and the more concentrated the irradiation range of the light, reducing the harm of glare to the human eye; the lower surface of the prism 9 of the present invention is a plane, and a long strip-shaped convex bud microstructure is added to the upper surface. The collimated light rays of the LED lamp bead 5 enter through the lower surface of the prism 9. When the entering light rays pass through the convex bud structure on the upper surface of the prism 9, the light ray direction will be changed by the convex bud structure, forming an elongated strip-shaped light spot on the receiving screen, meeting the customer's requirements for the transformation of the light spot shape; the filter lens 10 of the present invention is a flat circular thin sheet with flat upper and lower surfaces. The filter lens 10 is a colored transparent thin sheet formed by optically transparent PC injection molding with different color powders added. According to the customer's needs, the light spot of the LED lamp bead 5 passing through what color of the filter lens 10 will display the corresponding color light spot on the receiving screen; the polarizer 11 of the present invention adopts a double-layer superposition mode and utilizes the principle of light wedge angle superposition. The polarizer 11 is designed with a fixed angle of a°. Two polarizers 11 with the light-emitting surface facing up are placed in the connecting cover 8. The polarizer 11 close to the lens 6 is fixed, and the upper polarizer 11 rotates around the Z axis in the X-Y plane. When the polarization tooth directions of the two polarizers 11 are the same, the offset angle of the whole lamp light spot is 2a°; when the polarization tooth directions of the two polarizers 11 form a 90° angle, the offset angle of the whole lamp light spot is a°; when the polarization tooth directions of the two polarizers 11 are opposite, the position of the whole lamp light spot has no offset; moreover, the two polarizers 11 and the connecting cover 8 are not in a tightly fitting manner, so that the upper polarizer 11 can be gently rotated without disassembling the connecting cover 8, achieving the purpose of flexible deflection of the light spot.

[0075] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
