Description

Technical Field

[0001] The present disclosure relates to the technical field of lighting, and in particular to a two-way polarized lens and a lighting fixture. Background Art

[0002] We usually use point light sources for lighting. The light from point light sources often radiates in a circumferential direction in a ray shape, and the lighting effect changes with the change of the installation position of the point light source. When the point light source is set upward or downward, it is difficult for the light to illuminate the upper or lower direction due to the angle of the light. For example, people are usually accustomed to washing and putting on makeup in front of the sink and dressing table. Since the light source is set at the top of the head, the light will be easily blocked by the head, and then the face will be difficult to be illuminated. For this reason, some manufacturers have made further research and development.

[0003] For example, Chinese patent document CN218268910U discloses a fill light structure and a spotlight, including a lens and a lens holder, wherein the lens is arranged on the lens holder, the lens includes a lens outer peripheral surface, the lens holder is provided with a lens holder extension portion, the lens holder extension portion surrounds the lens holder outer peripheral surface, and the lens holder extension portion is used to reflect light emitted from the lens outer peripheral surface back to the lens.

[0004] However, the above-mentioned fill light structure and spotlight design have the following problems:

[0005] Although the above-mentioned fill light structure and spotlight can deflect the light through the lens bracket and the lens to illuminate the face, since it is necessary to observe through a mirror when washing and putting on makeup, the light will not be illuminated enough after deflection, resulting in the face seen through the mirror having the effect of rubbing the wall, which causes heavy shadows on the face and is difficult to meet the lighting needs of makeup. Utility Model Content

[0007] The purpose of this disclosure is achieved through the following technical solutions:

[0009] In one embodiment, the polarization angle of the first polarizing sawtooth is 20° to 40°; and / or

[0010] The polarization angle of the second polarizing sawtooth is 20° to 40°.

[0011] In one embodiment, the polarization angle of the first polarizing sawtooth is greater than the polarization angle of the second polarizing sawtooth.

[0012] In one embodiment, the first polarizing sawtooth includes an intersecting first polarizing horizontal inclined plane and a first polarizing vertical inclined plane, and the second polarizing sawtooth includes an intersecting second polarizing horizontal inclined plane and a second polarizing vertical inclined plane; the first polarizing vertical inclined plane is arranged opposite to the second polarizing vertical inclined plane, the first polarizing horizontal inclined plane is inclined to a side away from the second polarizing vertical inclined plane, and the second polarizing horizontal inclined plane is inclined to a side away from the first polarizing vertical inclined plane.

[0013] In one embodiment, the angle between the first polarized transverse inclined plane and the diameter line of the lens body is 10° to 35°; and / or the angle between the second polarized transverse inclined plane and the diameter line of the lens body is 0° to 25°.

[0014] In one embodiment, the plurality of first polarizing saw teeth include a plurality of first incident polarizing saw teeth and a plurality of first exit polarizing saw teeth, the plurality of first incident polarizing saw teeth are arranged on the light incident surface of the first light-transmitting body, the plurality of first exit polarizing saw teeth are arranged on the light exit surface of the first light-transmitting body, and the first incident polarizing saw teeth and the first exit polarizing saw teeth are arranged symmetrically one by one; and / or

[0015] The plurality of second polarizing saw teeth include a plurality of second incident polarizing saw teeth and a plurality of second exit polarizing saw teeth. The plurality of second incident polarizing saw teeth are arranged on the light incident surface of the second light-transmitting body, and the plurality of second exit polarizing saw teeth are arranged on the light exit surface of the second light-transmitting body, and the second incident polarizing saw teeth and the second exit polarizing saw teeth are symmetrically arranged one by one.

[0016] In one embodiment, the ratio of the light transmittance of the first light-transmitting body to the light transmittance of the second light-transmitting body is in a range of 1.5 to 2.5.

[0017] In one embodiment, the maximum ratio of the number of the first polarizing teeth to the number of the second polarizing teeth located on the same diameter of the lens body is 2.

[0018] In one embodiment, a lighting fixture includes a lamp tube, a light source module and a two-way polarized lens of any of the above embodiments; the light source module is arranged in the lamp tube, the two-way polarized lens is arranged at the light outlet of the lamp tube, and the light incident surface of the first light-transmitting body and the light incident surface of the second light-transmitting body are facing the light source module.

At the same time, since a plurality of second polarized sawtooths are arranged on the light incident surface of the second light-transmitting body and the light exiting surface of the second light-transmitting body, when light penetrates the second light-transmitting body, the light will be deflected by the refraction of the second polarized sawtooth. The polarization direction of the first polarized sawtooth is opposite to that of the second polarized sawtooth, so that the outgoing light of the first polarized sawtooth and the outgoing light of the second polarized sawtooth will be intertwined and projected in two opposite directions, that is, while the outgoing light of the second polarized sawtooth illuminates the human face, the outgoing light of the first polarized sawtooth can be projected onto the mirror and reflected to the human face for fill-in light.

The mirror then reflects the light to the human face for fill light, which can not only enhance the light intensity of the mirror but also reduce the shadow of the human face through fill light, thus avoiding the problem of heavy shadow on the face affecting the makeup when people put on makeup or wash at the dressing table.

DETAILED DESCRIPTION

[0030] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0034] like Figure 1 As shown, a two-way polarized lens 100 of an embodiment includes a lens body 110, a plurality of first polarized saw teeth 120 and a plurality of second polarized saw teeth 130; the lens body 110 includes a first light-transmitting body 1110 and a second light-transmitting body 1120 connected to each other; the plurality of first polarized saw teeth 120 are arranged on the light incident surface of the first light-transmitting body 1110 and the light emitting surface of the first light-transmitting body 1110; the plurality of second polarized saw teeth 130 are arranged on the light incident surface of the second light-transmitting body 1120 and the light emitting surface of the second light-transmitting body 1120; the polarization direction of the first polarized saw teeth 120 is opposite to the polarization direction of the second polarized saw teeth 130, and the outgoing light of the first polarized saw teeth 120 intersects with the outgoing light of the second polarized saw teeth 130.

[0035] It can be understood that the first polarizing sawtooth 120 is arranged on the light incident surface of the first light-transmitting body 1110 and the light emitting surface of the first light-transmitting body 1110. When light enters the light incident surface of the first light-transmitting body 1110, it will be emitted from the light emitting surface of the first light-transmitting body 1110. At the same time, a plurality of second polarizing sawtooths 130 are arranged on the light incident surface of the second light-transmitting body 1120 and the light emitting surface of the second light-transmitting body 1120, and the polarization direction of the first polarizing sawtooth 120 is opposite to the polarization direction of the second polarizing sawtooth 130, so that the outgoing light of the first polarizing sawtooth 120 intersects with the outgoing light of the second polarizing sawtooth 130, so that the outgoing light of the first polarizing sawtooth 120 is irradiated on the mirror, and the outgoing light of the second polarizing sawtooth 130 is irradiated on the face of the person, thereby enhancing the brightness of the mirror and the face of the person and avoiding the situation where heavy shadows are on the face.

[0036] It can be understood that compared with the fill light structure and spotlight in the prior art, the above-mentioned two-way polarized lens 100, by setting the first polarized sawtooth 120 and the second polarized sawtooth 130, simultaneously changes the emission directions of the first polarized sawtooth 120 and the second polarized sawtooth 130, so that the emission directions of the first polarized sawtooth 120 and the second polarized sawtooth 130 intersect, so that light in one direction is irradiated on the mirror, and light in the other direction is irradiated on the face of the person, thereby enhancing the brightness of the mirror and the face of the person, and avoiding the problem of poor lighting effect caused by heavy shadows on the face due to uniform light exposure when people put on makeup or wash at the dressing table.

[0037] like Figure 2As shown, specifically, the polarization angle of the first polarizing sawtooth 120 is 20° to 40°. It can be understood that by setting the polarization angle of the first polarizing sawtooth 120 within the range of 20° to 40°, the outgoing light of the first polarizing sawtooth 120 can be reflected to the face for fill light after being projected onto the mirror, thereby avoiding the polarization angle of the first polarizing sawtooth 120 being too large or too small, resulting in deviation in the fill light direction. Specifically, the polarization angle of the first polarizing sawtooth 120 can be 20°, 30° or 40°, which is not limited here, and those skilled in the art can also make other selections according to the position of the face.

[0038] like Figure 2 As shown, in another embodiment, the polarization angle of the second polarizing sawtooth 130 is 20° to 40°. It can be understood that by setting the polarization angle of the second polarizing sawtooth 130 within the range of 20° to 40°, the outgoing light of the second polarizing sawtooth 130 can be projected to illuminate the face, and avoid the polarization angle of the second polarizing sawtooth 130 being too large or too small, resulting in deviation from the position of the face. Specifically, the polarization angle of the second polarizing sawtooth 130 can be 20°, 30° or 40°, which is not limited here, and those skilled in the art can also make other selections according to the position of the face.

[0039] like Figure 1 As shown, specifically, the polarization angle of the first polarizing sawtooth 120 is greater than the polarization angle of the second polarizing sawtooth 130. It can be understood that, since the polarization angle of the first polarizing sawtooth 120 is greater than the polarization angle of the second polarizing sawtooth 130, the outgoing light of the first polarizing sawtooth 120 can be laterally interwoven with the outgoing light of the second polarizing sawtooth 130. When the outgoing light of the second polarizing sawtooth 130 is projected onto the face of a person and the outgoing light of the first polarizing sawtooth 120 is reflected onto the face of a person through a mirror, the light will be continuously dispersed between the mirror and the face of a person, so that the brightness transition between the face and the mirror is more uniform, thereby better illuminating the face of a person.

[0040] Combination Figure 1 and Figure 2As shown, in one embodiment, the first polarizing sawtooth 120 includes an intersecting first polarizing horizontal inclined plane 1210 and a first polarizing vertical inclined plane 1220, and the second polarizing sawtooth 130 includes an intersecting second polarizing horizontal inclined plane 1310 and a second polarizing vertical inclined plane 1320; the first polarizing vertical inclined plane 1220 is arranged opposite to the second polarizing vertical inclined plane 1320, the first polarizing horizontal inclined plane 1210 is inclined toward a side away from the second polarizing vertical inclined plane 1320, and the second polarizing horizontal inclined plane 1310 is inclined toward a side away from the first polarizing vertical inclined plane 1220. It can be understood that since the first polarizing horizontal inclined plane 1210 is inclined toward the side away from the second polarizing vertical inclined plane 1320, and the second polarizing horizontal inclined plane 1310 is inclined toward the side away from the first polarizing vertical inclined plane 1220, when the light is emitted from the first polarizing horizontal inclined plane 1310, the light will be refracted toward the side of the first polarizing sawtooth 120 close to the first polarizing vertical inclined plane 1220, and at the same time, when the light is emitted from the second polarizing horizontal inclined plane 1210, the light will be refracted toward the side of the second polarizing sawtooth 130 close to the second polarizing vertical inclined plane 1320, and the first polarizing vertical inclined plane 1220 and the second polarizing vertical inclined plane 1320 are arranged opposite to each other, that is, the outgoing light of the first polarizing horizontal inclined plane 1210 can be more evenly interwoven with the outgoing light of the second polarizing vertical inclined plane 1320, so that the light can be continuously dispersed between the mirror and the human face.

[0041] Combination Figure 1 and Figure 2 As shown, in one embodiment, the angle a between the first polarized horizontal inclined plane 1210 and the diameter line r of the lens body 110 is 10° to 35°. It can be understood that since the angle a between the first polarized horizontal inclined plane 1210 and the diameter line r of the lens body 110 is in the range of 10° to 35°, the outgoing light of the first polarized horizontal inclined plane 1210 can be tilted to the second polarized vertical inclined plane 1320 at a predetermined angle, and finally projected to the face through the mirror, which can better fill in the light of the face. Specifically, the angle a between the first polarized horizontal inclined plane 1210 and the diameter line r of the lens body 110 is specifically 10°, 25° or 35°, which is not limited here, and those skilled in the art can also adjust it according to the position of the face.

[0042] Combination Figure 2 and Figure 3As shown, the angle between the second polarized horizontal inclined plane 1310 and the diameter line r of the lens body 110 may be 0° to 25°. It can be understood that since the angle b between the second polarized horizontal inclined plane 1310 and the diameter line r of the lens body 110 is in the range of 0° to 25°, the outgoing light of the second polarized horizontal inclined plane 1310 can be tilted toward the first polarized vertical inclined plane 1220 at a predetermined angle, and finally illuminate the face, which can better fill in the light for the face. Specifically, the angle b between the first polarized horizontal inclined plane 1210 and the diameter line r of the lens body 110 is 0°, 15° or 25°, which is not limited here, and those skilled in the art can also adjust it according to the position of the face.

[0043] Combination Figure 1 and Figure 4 As shown, in one embodiment, the plurality of first polarized saw teeth 120 include a plurality of first incident polarized saw teeth 1230 and a plurality of first exit polarized saw teeth 1240, the plurality of first incident polarized saw teeth 1230 are arranged on the light incident surface of the first light transparent body 1110, the plurality of first exit polarized saw teeth 1240 are arranged on the light exit surface of the first light transparent body 1110, and the first incident polarized saw teeth 1230 and the first exit polarized saw teeth 1240 are arranged symmetrically one by one. It can be understood that by arranging a plurality of first incident polarizing saw teeth 1230 on the light incident surface of the first light-transmitting body 1110, when light enters from the light incident surface of the first light-transmitting body 1110, the light is deflected by the first incident polarizing saw teeth 1230 to the side of the second incident polarizing saw teeth 1330 of the lens body 110 and enters the first light-transmitting body 1110, and by arranging a plurality of first exit polarizing saw teeth 1240 on the light exit surface of the first light-transmitting body 1110, and symmetrically arranging the first incident polarizing saw teeth 1230 and the first exit polarizing saw teeth 1240 one by one, when light is emitted from the light exit surface of the first light-transmitting body 1110, the light will be further deflected by the first exit polarizing saw teeth 1240 to the side of the second exit polarizing saw teeth 1340 of the lens body 110, so that the light can be better projected onto the mirror, thereby ensuring the overall light direction.

[0044] Combination Figure 1 and Figure 4As shown, it may also be that the plurality of second polarizing saw teeth 130 include a plurality of second incident polarizing saw teeth 1330 and a plurality of second exit polarizing saw teeth 1340, the plurality of second incident polarizing saw teeth 1330 are arranged on the light incident surface of the second light transparent body 1120, the plurality of second exit polarizing saw teeth 1340 are arranged on the light exit surface of the second light transparent body 1120, and the second incident polarizing saw teeth 1330 and the second exit polarizing saw teeth 1340 are arranged symmetrically one by one. It can be understood that by arranging a plurality of first incident polarizing saw teeth 1230 on the light incident surface of the first light-transmitting body 1110, when light enters from the light incident surface of the first light-transmitting body 1110, the light is deflected by the first incident polarizing saw teeth 1230 to the side of the second incident polarizing saw teeth 1330 of the lens body 110 and enters the first light-transmitting body 1110, and by arranging a plurality of first exit polarizing saw teeth 1240 on the light exit surface of the first light-transmitting body 1110, and symmetrically arranging the first incident polarizing saw teeth 1230 and the first exit polarizing saw teeth 1240 one by one, when light is emitted from the light exit surface of the first light-transmitting body 1110, the light will be further deflected by the first exit polarizing saw teeth 1240 to the side of the second exit polarizing saw teeth 1340 of the lens body 110, so that the light can be better projected onto the mirror, thereby ensuring the overall light direction.

[0045] like Figure 1 As shown, specifically, the ratio of the light transmittance of the first light-transmitting body 1110 to the light transmittance of the second light-transmitting body 1120 ranges from 1.5 to 2.5. It can be understood that, since the ratio of the light transmittance of the first light-transmitting body 1110 to the light transmittance of the second light-transmitting body 1120 is in the range of 1.5 to 2.5, the light projected through the first light-transmitting body 1110 will be more than the light projected from the second light-transmitting body 1120, that is, the light biased toward the mirror will be more than the light biased toward the face, so that most of the light can be irradiated onto the mirror through the first light-transmitting body 1110 and then reflected onto the face to achieve a fill-in light effect, and a small part of the light can be directly irradiated onto the face through the second light-transmitting body 1120 to illuminate the face. Specifically, the ratio of the light transmittance of the first light-transmitting body 1110 to the light transmittance of the second light-transmitting body 1120 can be 1.5, 2 or 2.5, which is not limited here, and those skilled in the art can also make other choices as needed.

[0046] like Figure 1As shown, in one embodiment, the maximum ratio of the number of the first polarizing saw teeth 120 and the number of the second polarizing saw teeth 130 on the same diameter of the lens body 110 is 2. It can be understood that by setting the number of the first polarizing saw teeth 120 to be twice the maximum number of the second polarizing saw teeth 130 on the same diameter of the lens body 110, when the light enters the first light-transmitting body 1110 from the first polarizing saw teeth 120, the light emission amount is always greater than the light emission amount of the second polarizing saw teeth 130 entering the second light-transmitting body 1120, so that most of the light enters the first light-transmitting body 1110 from the first polarizing saw teeth 120 and irradiates the mirror, thereby reflecting the light to the face through the mirror, increasing the frontal illumination angle and reducing the shadow on the face.

[0047] Combination Figure 1 and Figure 5 As shown, specifically, a lighting fixture 10 includes a lamp tube 200, a light source module 300 and a two-way polarized lens 100; the light source module 300 is arranged in the lamp tube 200, the two-way polarized lens 100 is arranged at the light outlet of the lamp tube 200, and the light incident surface of the first light-transmitting body 1110 and the light incident surface of the second light-transmitting body 1120 face the light source module 300. It can be understood that the light source module 300 is arranged in the lamp tube 200, and the two-way polarized lens 100 is arranged at the light outlet of the lamp tube 200. When the light source module 300 injects light into the light outlet of the lamp tube 200, since the light incident surface of the first light transparent body 1110 and the light incident surface of the second light transparent body 1120 are facing the light source module 300, the light will be injected into the first light transparent body 1110 and the second light transparent body 1120, thereby causing the outgoing light of the first polarized sawtooth 120 to intersect with the outgoing light of the second polarized sawtooth 130.

[0048] like Figure 5 As shown, specifically, a focusing cup 210 is further provided in the lamp tube 200, and a light inlet mask 2110 of the focusing cup 210 is provided on the light-emitting surface of the light source module 300, and a light-emitting surface of the focusing cup 210 faces the two-way polarized lens 100. It can be understood that the focusing cup 210 is provided in the lamp tube 200, and the light inlet mask 2110 of the focusing cup 210 is provided on the light-emitting surface of the light source module 300, so that when the light source module 300 emits light, the light inlet of the focusing cup 210 converges the light into the focusing cup 210, and the light-emitting surface of the focusing cup 210 faces the two-way polarized lens, so that the light is more concentrated on the two-way polarized lens 100, ensuring that the light source module 300 can provide high-quality light lighting effects.

[0049] Compared with the prior art, the present invention has at least the following advantages:

[0050] When light passes through the first light-transmitting body 1110, the light will be deflected by the refraction of the first polarizing sawtooth 120. At the same time, since a plurality of second polarizing sawtooths 130 are arranged on the light incident surface of the second light-transmitting body 1120 and the light exiting surface of the second light-transmitting body 1120, when light passes through the second light-transmitting body 1120, the light will be deflected by the refraction of the second polarizing sawtooth 130. The polarization direction of the first polarizing sawtooth 120 is opposite to the polarization direction of the second polarizing sawtooth 130, so that the outgoing light of the first polarizing sawtooth 120 and the outgoing light of the second polarizing sawtooth 130 will be intertwined and projected in two opposite directions, that is, while the outgoing light of the second polarizing sawtooth 130 illuminates the face, the outgoing light of the first polarizing sawtooth 120 can be projected onto the mirror and reflected to the face for fill-in light.

[0051] Compared with the fill light structure and spotlight in the prior art, the second polarizing sawtooth 130 of the above-mentioned two-way polarized lens 100 can project a part of the light onto the human face, and can project another part of the light onto the mirror through the second polarizing sawtooth 130 to improve the illumination of the mirror. The mirror then reflects the light to the human face for fill light, which can not only enhance the light intensity of the mirror but also reduce the shadow of the human face through fill light, avoiding the problem of heavy shadow on the face affecting makeup when people put on makeup or wash at the dressing table.

[0052] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
