Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 19, an optical device 100 according to an embodiment of the present invention is disclosed, the disclosed optical device 100 may be installed at a light-emitting portion of a lighting fixture, so that light can be irradiated to a position to be illuminated through the optical device 100, and the disclosed optical device 100 includes a first substrate 110, a second substrate 120, and a first supporting member 130.

The first substrate 110 and the second substrate 120 are disposed opposite to each other, and the first supporting member 130 is supported between the first substrate 110 and the second substrate 120, so that a first optical space 140 is formed between the first substrate 110 and the second substrate 120.

The surface of the first substrate 110 may be provided with the light control structure 150, or the surface of the second substrate 120 may be provided with the light control structure 150, or both the surfaces of the first substrate 110 and the second substrate 120 may be provided with the light control structure 150. The light controlling structure 150 refers to a structure that can pass light and refract the passed light.

In the embodiments disclosed in the present application, the surface of the first substrate 110 and/or the second substrate 120 is provided with the light control structure 150, and the first substrate 110 and/or the second substrate 120 can refract the light passing through, so that the optical device 100 can achieve the light control effect. The optical device 100 is a two-layer substrate structure in which the thicknesses of the first substrate 110 and the second substrate 120 may be set thinner, and the first support 130 is disposed between the first substrate 110 and the second substrate 120, so that the first optical space 140 is formed between the first substrate 110 and the second substrate 120. At this moment, the optical device 100 is a hollow structure, and compared with a prism plate with the same thickness, the optical device 100 with the hollow structure has smaller weight, so that the lighting lamp has smaller weight, and the lighting lamp is more convenient to mount.

In addition, the optical device 100 has a two-layer substrate structure, so the optical device 100 also has good strength, is not easy to break, and has good safety and reliability.

In another alternative embodiment, the light controlling structure 150 may include a plurality of first light controlling protrusions 151 and a plurality of second light controlling protrusions 153. A first groove 152 is formed between any adjacent two of the first light-controlling protrusions 151, and a second groove 154 is formed between any adjacent two of the second light-controlling protrusions 153.

The first substrate 110 or the second substrate 120 may include a first surface and a second surface opposite to each other, the first light-controlling protrusion 151 may be disposed on the first surface, and the second light-controlling protrusion 153 may be disposed on the second surface. At this time, the first surface 111 and/or the second surface 112 of the first substrate 110 or the second substrate 120 are uneven, and the uneven first surface 111 and/or the uneven second surface 112 can achieve the effect of refracting light. At this time, the optical device 100 scatters the light, so as to prevent the light emitted from the lighting fixture from directly irradiating the user, thereby preventing glare. In this scheme, the first light-controlling protrusion 151 and the second light-controlling protrusion 153 have simple structures, so that the optical device 100 has a simple structure, is convenient to manufacture, and has a low cost.

Alternatively, the first light-controlling protrusion 151 and the second light-controlling protrusion 153 may have a stripe structure or a break-point structure, but other structures are also possible, and the disclosure is not limited thereto.

In the above embodiment, the first light-controlling protrusion 151 and the second light-controlling protrusion 153 are disposed on different surfaces of the same substrate, and therefore, the light beams can be transmitted in the same medium, and the light beams with large angles can be transmitted linearly without refraction, thereby resulting in poor optical performance of the optical device 100.

Based on this, in another alternative embodiment, the surface of the first substrate 110 may be provided with the first light-controlling protrusions 151. The surface of the second substrate 120 may be provided with second light-controlling protrusions 153. In this scheme, the first light-controlling protrusion 151 and the second light-controlling protrusion 153 are respectively disposed on the first substrate 110 and the second substrate 120, the first optical space 140 is disposed between the first substrate 110 and the second substrate 120, and the first optical space 140 is filled with air, so that light passes through different media, thereby enhancing the refraction effect on light with a large angle, and further improving the optical performance of the optical device 100.

In addition, the two surfaces of the first substrate 110 and the two surfaces of the second substrate 120 may be provided with the light control structures 150, so that the arrangement area of the light control structures 150 is increased, multiple refractions of the optics can be realized, and the light control effect of the optical device 100 is further improved.

Alternatively, as shown in fig. 6, the height and width of the first and second light-controlling

protrusions

151 and 153 may be the same. At this time, the refraction angle of the first light-controlling protrusion 151 and the refraction angle of the second light-controlling protrusion 153 are the same, so that the light is refracted twice and then gets closer to the center of the light source, thereby enabling the optical device 100 to have a high light-gathering effect. The light distribution curve corresponding to the optical device 100 shown in fig. 6 is shown in fig. 7.

In order to satisfy different light-controlling effects of the optical device 100, in another alternative embodiment, the heights of the first light-controlling protrusion 151 and the second light-controlling protrusion 153 are different. Alternatively, the first and second light-controlling

protrusions

151 and 153 have different widths. Still alternatively, the first light-controlling protrusion 151 and the second light-controlling protrusion 153 have different heights and widths. In this embodiment, the first light-controlling protrusion 151 and the second protrusion have different heights and/or widths, so that different light-controlling effects can be obtained, thereby further improving the optical performance of the optical device 100.

Alternatively, as shown in fig. 8, the first and second light-controlling

protrusions

151 and 153 have the same width. The height of the first light-controlling protrusion 151 is less than the width of the second light-controlling protrusion 153. At this time, the refraction angle of the second light-controlling protrusion 153 is greater than that of the first light-controlling protrusion 151, so that the light is far away from the center of the light source, and thus the optical device 100 has a high diffusion effect, thereby increasing the irradiation range of the optical device 100. The light distribution curve corresponding to the optical device 100 in fig. 8 is the light distribution curve shown in fig. 9.

Alternatively, the first light-controlling protrusions 151 may be disposed on an outer surface of the first substrate 110 and/or an inner surface of the first substrate 110. The second light-controlling protrusions 153 may be disposed on an outer surface of the second substrate 120 and/or an inner surface of the second substrate 120. The inner surface of the first substrate 110 and the inner surface of the second substrate 120 are oppositely disposed.

The first light-controlling protrusions 151 disposed on the outer surface of the first substrate 110 and the light-controlling protrusions disposed on the inner surface of the first substrate 110 may have the same structure, that is, the first light-controlling protrusions 151 disposed on the outer surface of the first substrate 110 and the light-controlling protrusions disposed on the inner surface of the first substrate 110 may have the same height and width. Alternatively, the heights of the first light-controlling protrusions 151 disposed on the outer surface of the first substrate 110 and the first light-controlling protrusions 151 disposed on the inner surface of the first substrate 110 may be different. And/or, widths of the first light-controlling protrusions 151 disposed on the outer surface of the first substrate 110 and the first light-controlling protrusions 151 disposed on the inner surface of the first substrate 110 may be different.

The second light-controlling protrusions 153 disposed on the outer surface of the second substrate 120 and the second light-controlling protrusions 153 disposed on the inner surface of the second substrate 120 may have the same structure, that is, the second light-controlling protrusions 153 disposed on the outer surface of the second substrate 120 and the second light-controlling protrusions 153 disposed on the inner surface of the second substrate 120 have the same height and width. Alternatively, the second light-controlling protrusions 153 disposed on the outer surface of the second substrate 120 and the second light-controlling protrusions 153 disposed on the inner surface of the second substrate 120 have different heights. And/or, the second light-controlling protrusions 153 disposed on the outer surface of the second substrate 120 and the second light-controlling protrusions 153 disposed on the inner surface of the second substrate 120 have different widths.

In another alternative embodiment, the first light-controlling protrusions 151 may have a stripe structure. The first light controlling protrusion 151 may have opposite first and

second sidewalls

1511 and 1512. The first light-controlling protrusions 151 have a first side connected to a surface of the first substrate 110 or the second substrate 120 and a second side distant from the surface of the first substrate 110 or the second substrate 120. The distance between the first sidewall 1511 and the second sidewall 1512 gradually decreases in a first lateral to second lateral direction.

In this scheme, the cross section of the first light-controlling protrusion 151 in the direction perpendicular to the extending direction thereof is a V-shaped cross section, and the included angles between the first sidewall 1511 and the second sidewall 1512 which are oppositely arranged are different, so that different reflected lights can be formed, and different light effects of the lighting fixture can be realized.

Further, an included angle between the first sidewall 1511 and the surface of the first substrate 110 or the second substrate 120 is a first angle, an included angle between the second sidewall 1512 and the surface of the first substrate 110 or the second substrate 120 is a second angle, and the first angle is different from the second angle. In this embodiment, the angles of the first sidewall 1511 and the second sidewall 1512 are different from the angles of the first substrate 110 and the second substrate 120, so that the reflection angles of the first sidewall 1511 and the second sidewall 1512 are different. When the first angle is larger than the second angle, the light is deflected to one side of the first sidewall 1511; when the second angle is larger than the first angle, the light is deflected to one side of the second angle. This structure can improve the polarization performance of the optical device 100.

Optionally, the difference between the first angle and the second angle is in a range of-80 ° to 80 °, and at this time, the first light-controlling protrusion 151 has a larger polarization range.

Or, in another alternative embodiment, the second light-controlling protrusions 153 may have a stripe structure. Second light-controlling protrusion 153 may have third and fourth opposing sidewalls 1531 and 1532. The second light-controlling protrusion 153 may have a third side connected to the surface of the first substrate 110 or the second substrate 120 and a fourth side distant from the surface of the first substrate 110 or the second substrate 120. In the direction of the third to fourth side, the distance between the third and

fourth sidewalls

1531 and 1532 gradually decreases.

In this scheme, the cross section of the second light-controlling protrusion 153 in the direction perpendicular to the extending direction thereof is a V-shaped cross section, and the included angles of the third sidewall 1531 and the fourth sidewall 1532 which are oppositely arranged are different, so that different reflected lights can be formed, and different light effects of the lighting fixture can be realized.

Further, an included angle between the third sidewall 1531 and the surface of the first substrate 110 or the second substrate 120 is a third angle, an included angle between the fourth sidewall 1532 and the surface of the first substrate 110 or the second substrate 120 is a fourth angle, and the third angle is different from the fourth angle. In this embodiment, the third and

fourth sidewalls

1531 and 1532 have different angles with respect to the first substrate 110 or the second substrate 120, so that the third and

fourth sidewalls

1531 and 1532 have different reflection angles. When the third angle is greater than the fourth angle, the light is deflected to one side of the third sidewall 1531; when the fourth angle is greater than the third angle, the light is deflected to one side of the fourth angle. This structure can improve the polarization performance of the optical device 100.

Optionally, the difference between the third angle and the fourth angle is in a range of-80 ° to 80 °, and at this time, the second light-controlling protrusion 153 has a larger polarization range.

Alternatively, as shown in FIG. 10, the first light-controlling protrusions 151 have a height and a width that are smaller than those of the second light-controlling protrusions 153. The first angle of the first light-controlling protrusions 151 is smaller than the second angle. The third angle of the second light-controlling protrusions 153 is smaller than the fourth angle. At this time, the polarization direction of the first light-controlling protrusion 151 is the same as the polarization direction of the second light-controlling protrusion 153, thereby increasing the polarization effect of the optical device 100. The corresponding light distribution curve of the optical device 100 shown in fig. 10 is shown in fig. 11.

Of course, the optical device 100 disclosed in the present application is not limited to the above-mentioned light distribution manners, and different light distribution types can be realized by the cooperation between the first light control protrusion 151 and the second light control protrusion 153.

In another alternative embodiment, the optical device 100 further includes a third substrate 160 and a second support 170. The first substrate 110, the second substrate 120, and the third substrate 160 are sequentially stacked. The second support 170 is supported between the second substrate 120 and the third substrate 160, so that a second optical space 180 is formed between the second substrate 120 and the third substrate 160, and at least one of the first substrate 110, the second substrate 120, and the third substrate 160 is provided with the light control structure 150.

In this embodiment, the number of layers of the substrate of the optical device 100 is large, which further improves the strength of the optical device 100 and further improves the safety and reliability of the optical device 100.

The optical device 100 of the present disclosure is not limited to the three-layer substrate structure, but may also be a substrate structure with other number, which is not limited herein.

Alternatively, the structure of the second support may be the same as that of the first support 130, and thus, the description thereof is omitted.

Alternatively, the third substrate 160 may be a diffusion plate, which can improve the light diffusion effect, so that the light passing through the optical device 100 is more uniform, and the anti-glare performance of the optical device 100 is further improved.

In another alternative embodiment, the light controlling structure 150 may include a plurality of first light controlling protrusions 151, second light controlling protrusions 153, and third light controlling protrusions 155. A first groove 152 is formed between any adjacent two of the first light-controlling protrusions 151. A second groove 154 is formed between any adjacent two of the second light-controlling protrusions 153. A third groove 156 is formed between any adjacent two of the third control light protrusions 155. The first light-controlling protrusion 151 is disposed on the surface of the first substrate 110, the second light-controlling protrusion 153 is disposed on the surface of the second substrate 120, and the third light-controlling protrusion 155 is disposed on the surface of the third substrate 160.

In this scheme, the light control structures 150 are disposed on the first substrate 110, the second substrate 120, and the third substrate 160, so as to further increase the arrangement area of the light control structures 150, thereby further increasing the refraction times of the optical device 100, and further improving the light control effect of the optical device 100.

Further, at least two of the first light-controlling protrusion 151, the second light-controlling protrusion 153, and the third light-controlling protrusion 155 are different in height. And/or widths of at least two of the first light-controlling protrusion 151, the second light-controlling protrusion 153, and the third light-controlling protrusion 155 are different. In this embodiment, the heights and widths of first light-controlling protrusion 151, second light-controlling protrusion and third light-controlling protrusion 155 are flexibly set, so that different light distribution effects can be obtained, thereby further improving the optical performance of optical device 100.

As shown in fig. 12, the first light-controlling protrusion 151 has a width greater than the widths of the second and third light-controlling protrusions 155. The height of the first light-controlling protrusions 151 is less than the height of the first and second light-controlling protrusions 153. The second light controlling protrusion 153 has the same height and width as the third light controlling protrusion 155. The optical device 100 with the structure can realize small-angle batwing light distribution. Fig. 13 shows a light distribution curve corresponding to the optical device 100 shown in fig. 12.

As shown in fig. 14, the width of the first light-controlling protrusion 151 is greater than the width of the second light-controlling protrusion 153. The width of the second light controlling protrusion 153 is greater than the width of the third light controlling protrusion 155. The height of the first light-controlling protrusions 151 is less than the height of the second light-controlling protrusions 153. The height of the second light controlling protrusion 153 is less than the height of the third light controlling protrusion 155. The optical device 100 with such a structure can realize large-angle batwing light distribution. Fig. 15 shows a light distribution curve corresponding to the optical device 100 shown in fig. 14.

Of course, the optical device 100 disclosed in the present application is not limited to the above-mentioned several light distribution manners, and different light distribution types can be realized by the cooperation among the first light control protrusion 151, the second light control protrusion 153, and the third light control protrusion 155.

In another alternative embodiment, the first substrate 110, the second substrate 120, and the first support 130 are a unitary structural member. In this scheme, optical device 100 can be formed by a set of dies, thereby reducing the assembly process between the components in optical device 100, and further making optical device 100 simple in structure, convenient to process, and low in cost. Alternatively, the optical device 100 may be manufactured by an extrusion molding process, in which case, the extrusion molding process may process optical devices 100 with various lengths according to the actual requirements of customers, without limiting the length of the optical device 100.

To further improve the optical performance of the optical device 100, in another alternative embodiment, the first substrate 110 may be provided with the light controlling structure 150, and the second substrate 120 may be a diffusion plate. In this scheme, the first substrate 110 of the optical device 100 is used for controlling light, the second substrate 120 of the optical device 100 is used for diffusing light, and when the light passes through the second substrate 120, the second substrate 120 can diffuse the light, so that the anti-glare performance of the optical device 100 is further improved.

When the second substrate 120 is a diffusion plate, the optical device 100 can be manufactured by a two-color extrusion molding process because the first substrate 110 and the second substrate 120 are made of different materials.

In another alternative embodiment, the light controlling structure 150 may include a first light controlling protrusion 151 and a second light controlling protrusion 153. A first groove 152 is formed between any adjacent two of the first light-controlling protrusions 151. A second groove 154 is formed between any adjacent two of the second light-controlling protrusions 153. The first light-controlling protrusion 151 may be disposed on the first substrate 110. The second light-controlling protrusion 153 may be disposed on a side of the second substrate 120 facing the first substrate 110, and a diffusion layer may be disposed on a surface of the second substrate 120 facing away from the second substrate 120. In this scheme, first substrate 110 and second substrate 120 all are provided with accuse light structure 150 to can further improve optical device 100's accuse light performance, simultaneously, second substrate 120 still is provided with the diffusion layer on deviating from the surface of one side of first substrate 110, and the diffusion layer can spread light, thereby makes the light through optical device 100 more even, makes optical device 100 have better anti-dazzle optical performance.

In this scheme, the first substrate 110 and the second substrate 120 are both provided with the light control structure 150, so that the optical device 100 can be made of the same material, and thus the optical device 100 can be made by a monochromatic extrusion molding process, and the affinity and the tightness between each part of the optical device 100 are better due to the fact that the monochromatic extrusion molding process adopts the same material, so that the strength of the optical device 100 is improved. Meanwhile, compared with the case that the second substrate 120 is directly used as a diffusion plate, the method of disposing a diffusion layer on the surface of the second substrate 120 has a simple structure and is convenient to manufacture, and further, the manufacturing scheme of the optical device 100 is simple.

Further, the diffusion layer may be a transflective functional layer. In this scheme, the diffusion layer can refract light rays with small angles, and the diffusion layer can reflect stray light with large angles, so that the stray light with large angles is prevented from passing through the diffusion layer, and the anti-glare performance of the optical device 100 is further improved.

Alternatively, the diffusion layer may be an ink layer, and of course, the diffusion layer may also be made of other diffusion materials, which is not limited herein.

In another alternative embodiment, the first and second light-controlling protrusions 153 may each have a stripe structure, and the first and second light-controlling

protrusions

151 and 153 extend in the same direction as the first support 130.
