Detailed ways

FIG. 1 is a schematic diagram of a lens and its installation environment according to an embodiment of the present invention. Referring to FIG. 1 , the lens 100 is disposed on a plane 10 . The plane 10 has an opening 12, and a light source 20 is emitted from a first side I of the plane 10 through the opening 12 toward a second side II of the plane, wherein the first side I and the second side II are opposite to each other. The lens 100 includes an annular portion 110 . The ring portion 110 is disposed on the second side II of the plane 10 and surrounds the opening 12 . The annular portion 110 has an inner wall 112 .

It is worth mentioning that an inner diameter Di defined by the inner wall 112 gradually increases from the side 102 of the annular portion 110 adjacent to the plane 10 to the other side 104 away from the plane 10 . In other words, the inner wall 112 is an inclined side wall. In addition, the inner wall 112 is located at least inside the opening 12 , and the minimum value of the inner diameter Di is smaller than the diameter of the opening 12 , for example.

When the light source 20 is emitted from the first side I through the opening 12 toward the second side II, at least part of the light source 20 will enter into the annular portion 110 of the lens 100 . In this embodiment, the material of the lens 100 is transparent or translucent material such as polymer transparent material (PMMA, PC, PET, etc.), glass, etc., and its refractive index is different from that of air. If the inclination angle of the inner wall 112 is properly designed, some light sources 20 will irradiate towards the plane 10 due to total internal reflection on the inner wall 112 . At this time, a ring-shaped halo effect will be produced on the plane 10 . It is worth mentioning that in this embodiment, a paint layer (not shown) can be selectively coated on the inner wall 112 or a colored ring portion 110 can be used. In this way, the halo generated on the plane 10 may have a color different from that of the light source 20 .

In detail, in this embodiment, the side 104 of the annular portion 110 away from the plane 10 is, for example, parallel to the plane 10 . Therefore, the light source 20 can irradiate the side 104 of the annular portion 110 away from the plane 10 after internal total reflection on the inner wall 112 , and then irradiate toward the plane 10 through the second total reflection. That is, the light can be irradiated on the plane 10 through two total internal reflections in the annular portion 110 .

Specifically, FIG. 2 is a cross-sectional view of the annular portion of the lens shown in FIG. 1 . Please refer to FIG. 1 and FIG. 2 at the same time. In this embodiment, an included angle A1 between the inner wall 112 and the plane 10 is, for example, from 40 degrees to 65 degrees. In addition, the ring portion 110 of the lens 100 also has an outer wall 114 , and the outer wall 114 and the inner wall 112 are opposite to each other. It is worth mentioning that an outer diameter Do defined by the outer wall 114 can gradually increase from the side 102 of the annular portion 110 adjacent to the plane 10 to the other side 104 away from the plane 10 or remain constant. In other words, an included angle A2 between the outer wall 114 and the plane 10 can range from 45 degrees to 90 degrees. In this way, after the light source 20 is totally internally reflected by the inner wall 112 and one side 104 of the annular portion 110, if it irradiates on the outer wall 114, it can be refracted on the outer wall 114 and emitted toward the plane 10, thereby forming a ring-shaped light on the plane 10. faint. Of course, in this embodiment, the inner wall 112 can also be selectively coated with colored pigments to help produce colored halos.

For example, the present invention can be applied to an embedded lighting device. In one embodiment, the plane 10 may be a ceiling, a wall, a desktop, a ground and other planar structures on which embedded lighting devices can be installed. The opening 12 is used for installing the embedded lighting device, and the light source 20 is, for example, the light provided by the embedded lighting device. In this embodiment, the lens 100 and the embedded lighting device are respectively installed on the opposite first side I and second side II on the plane 10, so as to beautify the light output effect of the embedded lighting device through the optical effect provided by the lens 100 . Specifically, the arrangement of the lens 100 can make the embedded lighting device have the effect of ring halo to increase the visual beauty.

In this embodiment, the embedded lighting device may be various known embedded lamps, and various light sources such as light bulbs, lamp tubes, and light emitting diodes may also be used, which are not particularly limited in the present invention. Therefore, the structure of the embedded lighting device is not specifically shown in FIG. 1 . In addition, in other embodiments, the lens 100 may not be designed in conjunction with the embedded lighting device, that is, the light source does not need to be assembled with a specific lampshade or lamp tube to form an embedded lighting device to be installed in the opening 12 . For example, under specific design requirements, any light source can be directly installed on the first side I of the plane 10 as the light source 20 for indirect lighting. At this time, the light source 20 emitted by the luminous light source can also create a visual effect of ring halo near the opening 12 .

It is worth mentioning that the inner wall 112 concentrates toward the center of the opening 12 , the more prominent the halo is. However, the more prominent the halo means that more light is irradiated toward the plane 10 and cannot be used for illumination, which may affect the intensity of the overall illumination light. Therefore, in actual design, the size of the inner diameter Di can be adjusted according to different design requirements to achieve the required illumination intensity and ideal halo effect. In addition, the angle of inclination between the material of the lens 100 and the outer wall 114 may affect the refraction angle of light and cause different halo distribution areas, so the inclination angle between the material of the lens 100 and the outer wall 114 can also be adjusted according to different design requirements to achieve Ideal for visual effects.

In addition, for the convenience of assembly, FIG. 3 is a schematic view of a lens according to another embodiment of the present invention, and FIG. 4 is a schematic cross-sectional view of the lens shown in FIG. 3 . Please refer to FIG. 3 and FIG. 4 at the same time. In addition to the ring portion 210 , the lens 200 optionally further includes an assembly portion 220 and a central portion 230 . In this embodiment, an implementation form in which the lens 200 has the annular portion 210 , the assembly portion 220 and the central portion 230 is described. In other embodiments, in addition to the annular portion 210 , the lens 200 may selectively have only one of the assembling portion 220 and the central portion 230 .

Specifically, the structural design of the annular portion 210 is similar to the structural design of the annular portion 110 in FIG. 1 . That is to say, the ring portion 210 has an inner wall 212 and an outer wall 214 opposite to each other. When the lens 200 is assembled on the plane 10 shown in FIG. 1 , an inner diameter Di defined by the inner wall 212 gradually increases from the side of the annular portion 210 adjacent to the opening 12 to the other side away from the opening 12 . Similarly, an outer diameter Do defined by the outer wall 214 gradually increases from the side of the annular portion 210 adjacent to the opening 12 to the other side away from the hole 12 or remains constant. Certainly, an included angle A1 between the inner wall 212 and the plane 10 is, for example, from 40 degrees to 65 degrees, and an included angle A2 between the outer wall 214 and the plane 10 may be from 45 degrees to 90 degrees.

In this embodiment, when the lens 200 is assembled on the plane 10 shown in FIG. 1 , the assembly portion 220 may be disposed on a side of the annular portion 210 close to the plane 10 . Specifically, the assembling portion 220 protrudes from the annular portion 210 toward the first side I, for example. A contact surface 222 of the assembly part 220 can contact the edge of the hole 12 on the plane 10 to fix the lens 200 on the plane 10 . In other words, the assembly part 220 can be embedded in the opening 12 . However, in other embodiments, the assembling part 220 may also be configured to be assembled on a light outlet of an embedded lighting device. Therefore, the above description is only for illustration and is not intended to limit the installation manner or implementation form of the assembling part 220 . In an embodiment, the assembly part 220 may also be provided with a buckle structure to facilitate the assembly between the lens 200 and other components.

In addition, in this embodiment, the central portion 230 is connected to the inner wall of the annular portion 210 to cover the opening 12 . When the lens 200 is assembled on the plane 10 shown in FIG. 1 , the central portion 230 can provide light diffusion so that the light source 20 can evenly emit light from different directions. In this embodiment, the central part 230 may have a flat structure, but the present invention is not limited thereto. In other embodiments, the central part 230 may have different structural designs.

For example, FIG. 5 is a schematic cross-sectional view of a lens according to another embodiment of the present invention. Referring to FIG. 5 , the lens 300 is substantially the same as the lens 200 of the aforementioned embodiment, and the same elements will be marked with the same symbols. However, the central portion 330 of the lens 300 is a convex central portion 330 . That is to say, the central part 330 is a convex lens structure to provide the effect of concentrating light to achieve different light output effects. Of course, in other embodiments, the central portion 330 may be a concave lens structure, a convex-concave lens structure, a biconcave lens structure, a biconvex lens structure, a fog lens, etc. to achieve different light output effects. In general, regardless of the design of the central part 330 and the design of the assembling part 220, the design of the annular part 210 can provide the effect of total internal reflection of light so that the visual effect of the annular halo formed around the annular part 210 can increase the overall lighting design beauty.

6 and 7 are schematic diagrams of the annular portion of the lens according to other embodiments of the present invention. Please refer to FIG. 6 , the annular portion 410 has an inner wall 412 and an outer wall 414 opposite to each other, wherein a contour surrounded by the outer wall 414 may be a wavy shape composed of multiple arcs. That is to say, a contour surrounded by the outer wall 414 is composed of multiple arcs. In addition, please refer to FIG. 7 , the annular portion 510 has an inner wall 512 and an outer wall 514 opposite to each other, wherein a contour surrounded by the outer wall 514 is a hexagon. In other words, the present invention does not limit the contour of the outer wall in the annular portion. In other embodiments, the contour surrounded by the outer wall may be a circle, a star, other polygons or irregular shapes.

It is worth mentioning that the contour surrounded by the inner wall in the annular portion does not need to be particularly limited. When the lens of the present invention is disposed on a plane with an opening, the contour surrounded by the inner wall in the annular portion only needs to substantially surround the opening. The hole then contributes to the formation of the annular halo on the plane. Therefore, the contour surrounded by the inner wall is not limited to be a circle, it can be waved as shown in FIG. 6 , or other forms such as polygonal, elliptical and so on.

To sum up, the lens of the present invention has an annular portion, and when the lens is disposed on a plane, an inner wall of the annular portion intersects the plane at an angle. When the light irradiates from one side of the plane through the opening on the plane to the side where the annular part is located, it will partially enter the annular part and undergo internal total reflection on the inner wall. The light rays after total internal reflection will be irradiated on the plane to form an annular halo. In this way, the installation of the lens helps to enhance the aesthetic feeling of the visual effect.

Although the present invention has been disclosed above with the embodiments, it is not intended to limit the present invention. Any person skilled in the art can make appropriate changes or equivalent replacements without departing from the spirit and scope of the present invention, so the protection scope of the present invention The scope defined in the claims shall prevail.
