[0002] The illumination range and light spot effect of a lamp are important indicators to measure its performance. With the rapid development of lighting technology today, the design and innovation of lamps are constantly promoting the improvement of lighting effects.

[0003] Traditional lighting fixtures often face challenges with excessively concentrated light spots and a limited illumination range. This limited illumination range makes them incapable of meeting the lighting requirements of large spaces, particularly those requiring wide-angle illumination or uniform illumination of large areas, such as large conference rooms, exhibition halls, and outdoor plazas. This not only limits the lighting's application scenarios but also impacts lighting uniformity and comfort.

[0004] Therefore, it is urgent to design a wide-angle spot structure that can expand the spot area and perform wide-angle diffusion. Utility Model Content

[0005] In view of this, the present invention provides a wide-angle light spot structure and a lamp containing the same, which is used to solve the problem in the prior art that the light spot of the lamp is too concentrated and cannot be diffused at a wide angle.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a wide-angle light spot structure, which includes a shell, a light source module, a convex lens and a biconcave lens. The light source module is arranged inside the shell, the convex lens is arranged inside the shell and in front of the light source module, and the biconcave lens is arranged in the shell and in front of the convex lens, wherein the front is the front of the irradiation direction of the light source module.

[0007] As an embodiment of the present invention, the shell is a cylindrical structure, the light source module and the biconcave lens are arranged at both ends of the shell, the convex lens is located between the light source module and the biconcave lens, and the middle of the convex lens bulges toward the direction of the biconcave lens.

[0008] As an embodiment of the present invention, the wide-angle light spot structure further includes a shell cover, which is disposed on the housing and close to one end of the biconcave lens.

[0009] As an embodiment of the present invention, a first slot is formed on the inner wall of one end of the shell, the edge of the biconcave lens matches and connects to the first slot, and the light source module is provided at the other end of the shell.

[0010] As an embodiment of the present invention, a second slot is formed on the inner wall of the housing at a preset distance from the first slot, and the edge of the convex lens matches and is connected to the second slot.

[0011] As an embodiment of the present invention, the convex lens and the biconcave lens are made of any one of glass, plastic, resin, quartz and crystal.

[0012] As an embodiment of the present invention, the surfaces of the convex lens and the biconcave lens are polished.

[0013] As an embodiment of the present invention, the light source module includes at least one light emitting body, which is arranged at the geometric center of one end of the shell, and the light emitted by the light emitting body is irradiated toward the other end of the shell.

[0016] Compared with the prior art, the wide-angle light spot structure provided by the embodiment of the present invention has the following advantages:

[0017] 1. In the wide-angle light spot structure provided by the present invention, by cleverly combining the light source module, the convex lens and the biconcave lens, the convex lens can converge the original light, thereby enhancing the light intensity at the center; and then by setting the biconcave lens, it can receive the converged light and diffuse it to a wider angle, thereby achieving a wide-angle diffusion effect of the light spot, which not only realizes the effective focusing of the light source, but also ensures that the light spot is evenly diffused within a wide-angle range, effectively solving the problem of excessive concentration of the light spot of the lamp in the prior art and the inability to perform wide-angle diffusion.

[0018] 2. In the wide-angle light spot structure provided by the present invention, a first card slot and a second card slot are formed on the inner wall of the shell for matching and connecting the double concave lens and the convex lens.

[0019] 3. In the wide-angle light spot structure provided by the present invention, the surfaces of the convex lens and the biconcave lens are polished. First, the surfaces can be made smoother, which can reduce light scattering and irregular reflection, thereby improving the light transmittance of the lens and making the lamp brighter; second, the defects on the lens surface can be removed, and the clarity of the image can be improved to meet the occasions requiring high-quality lighting; third, the polished lens surface is harder and can resist scratches and wear, thereby extending the service life of the convex lens, the biconcave lens and the lamp.

[0036] Example 1

[0037] See also Figure 1 As shown, the first embodiment of the present invention discloses a wide-angle light spot structure 1, which can be used in, but is not limited to, lamps.

[0038] Please combine Figure 1 and Figure 2 As shown, the wide-angle spot structure 1 includes a shell 11, a light source module 12, a convex lens 13 and a biconcave lens 14, the light source module 12 is arranged inside the shell 11, the convex lens 13 is arranged inside the shell 11 and is located in front of the light source module 12, the biconcave lens 14 is arranged in the shell 11 and is located in front of the convex lens 13, wherein the front is the front of the irradiation direction of the light source module 12.

[0039] Specifically, the light source module 12 is disposed at one end of the housing 11 for emitting original light, and the emitted light is directed toward the other end of the housing 11 .

[0040] Specifically, the convex lens 13 is disposed in front of the light source module 12 to converge the original light to form a focusing effect, thereby enhancing the light intensity at the center, forming a high-intensity light spot, optimizing the focusing effect of the light, and improving the utilization rate of light energy.

[0041] Specifically, the biconcave lens 14 is arranged in front of the convex lens 13 to receive the converged light and diffuse it to a wider angle. It can effectively receive and redistribute the light after being focused by the convex lens 13, diffuse it to a wider angle, and maintain the uniformity of the light spot, avoiding the problem of uneven light intensity attenuation in traditional diffusion methods.

[0042] It can be understood that by cleverly combining the light source module 12, the convex lens 13 and the biconcave lens 14, the convex lens 13 can converge the original light, thereby enhancing the light intensity in the center; and then by setting the biconcave lens 14, it can receive the converged light and diffuse it to a wider angle, thereby achieving a wide-angle diffusion effect of the light spot, which not only realizes the effective focusing of the light source, but also ensures that the light spot is evenly diffused within a wide-angle range, effectively solving the problem of excessive concentration of the light spot of the lamp in the prior art and inability to perform wide-angle diffusion.

[0043] Specifically, the housing 11 is used to carry and fix the light source module 12 , the convex lens 13 and the biconcave lens 14 , ensuring the stability and durability of the overall structure.

[0044] Optionally, the cross-sectional shapes of the housing 11 , the convex lens 13 and the biconcave lens 14 are all any one of polygonal, rectangular, circular and elliptical.

[0045] Specifically, in the embodiment of the present invention, the cross-sectional shapes of the housing 11 , the convex lens 13 , and the biconcave lens 14 are all circular as an example for detailed description, but this should not constitute a limitation to the present invention.

[0046] Furthermore, please combine Figure 2 and Figure 3 As shown, the light source module 12 includes at least one light emitting body 121 . The light emitting body 121 is located at the geometric center of one end of the housing 11 , and the light emitted by the light emitting body 121 is irradiated toward the other end of the housing 11 .

[0047] Specifically, the light emitting element 121 is located at the geometric center of one end of the housing 11, and emits light toward the other end of the housing 11. Optionally, the light emitting element 121 may be a high-brightness LED or other high-efficiency energy source. The embodiment of the present invention is specifically described using a high-brightness LED, but this should not be construed as limiting the present invention.

[0048] Furthermore, the shell 11 is a cylindrical structure, the light source module 12 and the biconcave lens 14 are arranged at both ends of the shell 11, the convex lens 13 is located between the light source module 12 and the biconcave lens 14, and the middle of the convex lens 13 bulges toward the direction of the biconcave lens 14.

[0049] Specifically, the housing 11 is a circular cylindrical structure, more specifically, a cylindrical structure with two open ends. It can be understood that the light source module 12 and the biconcave lens 14 are respectively disposed at the two ends of the cylindrical structure 11 with two open ends, while the convex lens 13 is disposed within the cylindrical structure 11 and is located at any position between the light source module 12 and the light diffuser.

[0050] Furthermore, the wide-angle light spot structure 1 further includes a shell cover 15 , which is disposed on the housing 11 and close to one end of the biconcave lens 14 .

[0051] Specifically, the light source module 12 and the biconcave lens 14 are respectively disposed at both ends of the housing 11 having a cylindrical structure and open at both ends, and then the housing cover 15 is disposed on the housing 11 and covers the biconcave lens 14 .

[0052] More specifically, the shell cover 15 is an annular structure. Optionally, the shell cover 15 can be connected to the housing 11 in a threaded connection, a snap-on connection, a fixing piece connection, etc., which is not specifically limited in the present invention.

[0053] Furthermore, please combine Figure 3 、 Figure 4 as well as Figure 5As shown, a first slot 111 is formed on the inner wall of one end of the housing 11 , and the edge of the biconcave lens 14 matches and connects to the first slot 111 . The light source module 12 is disposed at the other end of the housing 11 .

[0054] Furthermore, a second slot 112 is formed at a preset distance between the inner wall of the housing 11 and the first slot 111 , and the edge of the convex lens 13 matches and connects to the second slot 112 .

[0055] Specifically, the second card slot 112 is formed on the inner wall of the shell 11 and is at a preset distance from the first card slot 111. The edge of the convex lens 13 matches and is connected to the second card slot 112. More specifically, the preset distance position can be understood as being located at any position between the light source module 12 and the biconcave lens 14. As long as the convex lens 13 is arranged between the light source module 12 and the biconcave lens 14, the convex lens 13 can converge the light emitted by the light source module 12, and then the biconcave lens 14 will diffuse the converged light to a wider angle, thereby achieving a wide-angle diffusion effect of the light spot.

[0056] Specifically, by forming a first card groove 111 and a second card groove 112 on the inner wall of the shell 11 for matching and connecting the double concave lens 14 and the convex lens 13, the mixed light structure can be designed as a modular structure, which is convenient for users to replace or upgrade components such as the light source module 12, the convex lens 13 and the double concave lens 14 according to actual needs, thereby improving the maintainability and scalability of the mixed light structure.

[0057] Furthermore, the convex lens 13 has a focal length, which determines the position of the focal point of the light after it passes through the lens. In different lamps, the convex lens 13 is determined according to its application site and design requirements, and its focal length varies due to factors such as the lamp type, light source type, and the required spot size, and it is impossible to give a uniform range. In addition, the convex lens 13 also has a curvature, and its curvature represents the degree of surface curvature of the convex lens 13. The curvature of the convex lens 13 has a direct impact on the degree of refraction of the light and can determine the focusing effect of the light. Since in different lamp designs, it is necessary to comprehensively consider factors such as the light source type, focusing effect, required spot size, and light angle to select a suitable curvature of the convex lens 13, it is impossible to give a uniform range. Therefore, the present invention does not specifically limit the curvature of the convex lens 13, as long as the convex lens 13 satisfies the function of converging the original light to enhance the light intensity at the center.

[0058] Furthermore, the biconcave lens 14 also has a focal length, which represents the degree of divergence or expansion of the light. In different lamps, the appropriate focal length of the biconcave lens 14 must be selected based on a comprehensive consideration of factors such as light divergence, imaging characteristics, system focal length adjustment, beam expansion, and aberration correction. A uniform range cannot be given. Therefore, the present invention does not impose specific limitations on the focal length of the biconcave lens 14; as long as the biconcave lens 14 receives the converged light and spreads it over a wider angle, it will be sufficient.

[0059] Optionally, the convex lens 13 and the biconcave lens 14 are made of any one of glass, plastic, resin, quartz and crystal.

[0060] Specifically, in different lamps, the materials of the convex lens 13 and the biconcave lens 14 need to comprehensively consider factors such as optical performance, durability, processing difficulty and cost to meet the specific design requirements of the corresponding lamps. Therefore, the present invention does not specifically limit the materials of the convex lens 13 and the biconcave lens 14, as long as the convex lens 13 has the function of converging the original light to enhance the light intensity at the center, and the biconcave lens 14 has the function of receiving the converged light and diffusing it to a wider angle.

[0061] Furthermore, the surfaces of the convex lens 13 and the biconcave lens 14 are polished.

[0062] Specifically, the surfaces of the convex lens 13 and the biconcave lens 14 are polished. First, the surfaces can be made smoother, which can reduce light scattering and irregular reflection, thereby improving the light transmittance of the lens and making the lamp brighter; second, the defects on the lens surface can be removed, and the clarity of the image can be improved to meet the needs of occasions requiring high-quality lighting; third, the polished lens surface is harder and can resist scratches and wear, thereby extending the service life of the convex lens 13, the biconcave lens 14 and the lamp.

[0063] Specifically, the surfaces of the convex lens 13 and the biconcave lens 14 are coated with an anti-reflection coating, which can significantly reduce the reflection of light on the surfaces of the convex lens 13 and the biconcave lens 14, thereby reducing the loss of light. In addition, by reducing reflection, the transmittance of the lens can be increased, allowing more light to pass through the lens, improving the lighting efficiency of the lamp, and improving the transmittance and utilization efficiency of light.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
