[0028] like Figures 1 to 6 As shown, an embodiment of the present utility model provides a novel optical lens, characterized in that it includes:
[0029] Outer lens 1 and middle lens 2;
[0030] The intermediate lens 2 is disposed inside the outer lens 1 .
[0031] In the embodiment of the present invention, the combination of outer lens 1 and middle lens 2 achieves light focusing and diffusion effects, while increasing light refraction and reflection to change the propagation direction and path of the light. Outer lens 1 can cause light to mix with focused and scattered light internally, causing light to reflect off the outer surface of outer lens 1, thereby changing the propagation direction of the light and achieving a light mixing effect, making the originally concentrated light more dispersed and uniform. Middle lens 2 has a focusing function. Light directly passes through middle lens 2, refracting the divergent light source into parallel light. It can also refocus the light diffused by outer lens 1 and re-concentrate it. By adjusting the curvature and position of the lens, the degree and range of focusing can be changed to achieve different lighting effects. The combination of outer lens 1 and middle lens 2 can cause light to mix with focused and scattered light internally, thereby changing the propagation direction and path of the light. After multiple total reflections, the originally concentrated light is diffused and mixed, making the strong light softer and more uniform, reducing glare and improving the lighting comfort and visual effect.
[0032] like Figures 1 to 6 As shown, the outer ring lens 1 is a cylinder with openings at both ends, and the diameters of the openings at both ends are different.
[0033] In the embodiment of the present invention, since the diameters of the openings at both ends of the outer ring lens 1 are different, a mixture of convergence and astigmatism will occur when the light propagates in the lens, thereby changing the intensity and angle of the light.
[0034] like Figures 1 to 6 As shown, a flange 12 is provided around the end of the outer ring lens 1 with a larger opening diameter.
[0035] In an embodiment of the present invention, the flange 12 is a flange flange, which provides the function of supporting and fixing the lens, so that it can be stably installed in the optical system. The lens is connected to other optical elements or devices through the flange flange 12 to ensure the position and stability of the lens; the presence of the flange flange can effectively prevent light from leaking around the lens, form a closed environment, maintain the propagation path of light inside the lens, and reduce light loss; the shape and material selection of the flange flange can reduce the scattering and interference of light, provide a flat contact surface, avoid unnecessary reflection or refraction, and maintain the purity and stability of the light.
[0036] like Figures 1 to 6 As shown, the outer surface of the outer ring lens 1 is provided with cross wave lines 13 which are divided into spiral sections, and the surface of the cross wave lines 13 is smooth.
[0037] In an embodiment of the present invention, the outer surface of the outer ring lens 1 is provided with a cross wavy pattern 13, which can make the light reflect and refract multiple times on the lens surface, and the light can be scattered and focused at different angles, thereby achieving a mixed effect of focusing and astigmatism; because the cross wavy pattern 13 can make the light reflect and refract multiple times inside the lens, the light can interact freely inside the lens, which can improve the uniformity and mixing of the light, and make the light passing through the lens more uniform and softer; the spiral scale distribution of the cross wavy pattern 13 makes the lens surface have no obvious intersection line, which can avoid obvious light deviation or shape change during the observation process, and provide a smoother and continuous observation experience; the smooth surface of the cross wavy pattern 13 allows light to pass through the lens surface more smoothly, and by reducing the scattering and reflection of light, the transmittance of light is improved, and the light passing through the lens is brighter and clearer.
[0038] like Figures 1 to 6 As shown, the positive curvature radius curve of the cross wave pattern 13 is a convergent light mixing curve, and the negative curvature radius curve is a divergent light mixing curve.
[0039] In the embodiment of the present utility model, reference Figure 4, the figure is a side view of light entering the outer ring lens 1, and the cross-wave pattern 13 is shown as a γ-plane wavy line in the figure, showing the subtle fluctuations of light on the lens surface; the convex curve of the γ-plane wavy line is a positive curvature radius curve, which is a convergent light mixing curve, indicating that the light converges inward on the lens surface and gathers into a point or a small area; the positive curvature radius curve makes the light converge inward on the lens surface, forming a focusing effect, thereby enhancing the intensity and brightness of the light; the concave curve of the γ-plane wavy line is a reverse curvature radius curve, which is a divergent light mixing curve, indicating that the light diverges outward on the lens surface and spreads out. The reverse curvature radius curve makes the light diverge outward on the lens surface, forming a divergent effect, which can spread the light and increase the dispersion and coverage of the light;
[0040] refer to Figure 5 , the figure is a plan view of the lens, and the cross-wave pattern 13 is shown in the figure as a C-plane wavy line surrounding the lens, showing the subtle fluctuations of light on the lens surface. The convex curve of the C-plane wavy line is a positive curvature radius curve, which is a convergent light mixing curve, indicating that the light converges inward on the lens surface and gathers into a point or a small area. The positive curvature radius curve makes the light converge inward on the lens surface, forming a focusing effect, thereby enhancing the intensity and brightness of the light; the concave curve of the C-plane wavy line is a reverse curvature radius curve, which is a divergent light mixing curve, indicating that the light diverges outward on the lens surface and spreads out. The reverse curvature radius curve makes the light diverge outward on the lens surface, forming a divergent effect, which can diffuse the light and increase the dispersion and coverage of the light.
[0041] like Figures 1 to 6 As shown, the curvature radius of the reflection surface curve of the cross wavy lines 13 is greater than R2, and the incident angle is greater than the critical angle of total reflection.
[0042] In the embodiment of the present invention, the reflection surface curve refers to the trajectory or path of light on the reflection surface. When light is incident from one medium to another, it will be reflected when it encounters the interface, and the light will be reflected out according to a certain rule. The reflection surface curve describes the bending degree and direction change of the light on the reflection surface. According to the law of reflection, the reflection angle is equal to the incident angle, so the shape and curvature of the reflection surface curve will affect the reflection angle and direction of the light. By designing the reflection surface curve, it is possible to control and adjust the light, such as focusing the light, diffusing the light, or changing the propagation direction of the light; by designing the reflection surface curve so that the incident angle is greater than the critical angle of total reflection, when the light is incident from the medium to the lens, if the incident angle is less than the critical angle of total reflection, the light will be refracted and a part of it will be transmitted into the interior of the medium, and when the incident angle is greater than the critical angle of total reflection, the light will be totally reflected and all will be reflected back into the interior of the lens, so that the light can be completely reflected, thereby improving the reflection efficiency and utilization rate of the light;
[0043] The curvature radius of the reflective surface curve is greater than R2, that is, the curvature radius is larger than the curvature radius of the convex surface, which can make the reflective surface more curved, making the reflected light more concentrated and focused. Through the curvature of the reflective surface, the light can be reflected to a smaller area, thereby achieving more precise light control and focusing and diffusing effects.
[0044] like Figures 1 to 6 As shown, one side of the intermediate lens 2 is a flat surface 21 and the other side is a convex surface 22 .
[0045] In an embodiment of the present invention, the intermediate lens 2 is a plano-convex lens, which is a lens with one convex side and one flat side, and is used to converge parallel light or convert a point light source into parallel light; the outer ring lens 1 and the intermediate lens 2 have the same focal point, which is located at the position of the light-emitting surface of the LED chip; when focusing, the light spot becomes larger or smaller, but the light spot from the intermediate convex lens and the light from the outer total reflection part can be kept overlapping, and the light is uniform.
[0046] like Figures 1 to 6 As shown, light-mixing beads are provided on the convex surface 22 .
[0047] In an embodiment of the present utility model, light-mixing beads are provided on the convex surface 22, that is, many tiny raised structures are arranged on the convex surface; during the focusing process, the size of the light spot can be controlled by adjusting the position of the intermediate lens 2. By setting the light-mixing beads on the convex surface 22, the light spot emitted by the intermediate lens and the light of the total reflection part of the outer lens can be kept overlapping, which can ensure the uniformity and consistency of the light; the arrangement of the light-mixing beads on the convex surface 22 can achieve a light mixing effect, and the tiny raised structures will scatter the light, so that the light is more evenly dispersed and mixed in the lens system, which can improve the uniformity and visual effect of the light.
[0048] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
