Description

Technical Field

[0001] The utility model relates to a zone-controlled electrochromic lens. Background Art

[0002] At present, road monitoring cameras play an important role in ensuring traffic safety and promoting urban management. When road monitoring cameras encounter local strong light (high beam and sunlight, etc.), exposure distortion or even blindness may occur in some areas of the monitoring screen. Most of the lenses used in road monitoring cameras are ordinary and cannot suppress strong light. Even if electrochromic lenses are used, the existing electrochromic lenses can only suppress strong light by changing the color of the entire surface. Therefore, they can only reduce the exposure of the overall monitoring screen and it is difficult to reduce the exposure locally, resulting in poor monitoring image quality. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an electrochromic lens with zone control, which can independently control the color change of a local area. When used in a road monitoring camera, it can suppress local strong light, thereby suppressing the overexposure of the local area in the monitoring picture, and can locally reduce the exposure of the monitoring picture to improve the monitoring image quality.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a zone-controlled electrochromic lens, which includes a front conductive glass and a rear conductive glass;

[0005] The front conductive glass comprises a front substrate and at least two first conductive film portions which are electrically isolated from each other and are arranged on the rear end surface of the front substrate;

[0006] The rear conductive glass comprises a rear substrate and at least two second conductive film portions which are electrically isolated from each other and are arranged on the front end surface of the rear substrate, wherein the second conductive film portions are aligned with the corresponding first conductive film portions;

[0007] A sealed insulating rubber frame is provided between the front conductive glass and the rear conductive glass. The inner side of the sealed insulating rubber frame is filled with an electrochromic material. The electrochromic material is located between the first conductive film portion and the second conductive film portion.

[0008] Furthermore, the first conductive film portion and the second conductive film portion correspond to each other one by one.

[0009] Furthermore, a plurality of the first conductive film portions and a plurality of the second conductive film portions are sequentially distributed along the circumferential direction.

[0010] The shapes of the first conductive film portion and the second conductive film portion are further provided, and the first conductive film portion and / or the second conductive film portion are fan-shaped structures.

[0011] Furthermore, electrical blocking grooves are provided between any adjacent first conductive film portions and between any adjacent second conductive film portions.

[0012] Furthermore, the sealing insulating rubber frame is arranged between the outer periphery of the front conductive glass and the outer periphery of the rear conductive glass.

[0013] Furthermore, a first lug portion corresponding to the first conductive film portion is provided on the outer periphery of the front substrate, and the first conductive film portion extends to the corresponding first lug portion to form a first power connection portion;

[0014] A second lug portion corresponding to the second conductive film portion is provided on the outer periphery of the rear substrate, and the second conductive film portion extends to the corresponding second lug portion to form a second power connection portion;

[0015] The first power connection portion and the second power connection portion are both used to be connected to a power source.

[0016] Furthermore, the first lug portion corresponds to the first conductive film portion one by one, and the second lug portion corresponds to the second conductive film portion one by one.

[0017] Further, the first lug portion and the second lug portion are staggered in the circumferential direction.

[0018] Furthermore, the front substrate and the rear substrate are both transparent glass plates, and the first conductive film portion and the second conductive film portion are both ITO films.

[0019] After adopting the above technical solution, when the corresponding first conductive film part and the corresponding second conductive film part are energized, the electrochromic material between the energized first conductive film part and the energized second conductive film part changes color under the action of the electric field, while the electrochromic material between the unenergized first conductive film part and the unenergized second conductive film part does not change color. Therefore, the partition-controlled electrochromic lens of the embodiment of the present application can independently control the color change of the local area. When the partition-controlled electrochromic lens of the embodiment of the present application is applied to a road monitoring camera, if local overexposure occurs in the monitoring picture, the first conductive film part and the second conductive film part of the corresponding overexposed area are energized separately, so that the corresponding area changes color separately to suppress the local strong light, thereby suppressing the local overexposure in the monitoring picture, and being able to partially reduce the exposure of the monitoring picture to improve the monitoring picture quality, solving the problem of local overexposure of the monitoring picture.

[0026] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0027] like Figures 1 to 6 As shown, a zone-controlled electrochromic lens comprises a front conductive glass 100 and a rear conductive glass 200;

[0028] The front conductive glass 100 comprises a front substrate 1 and at least two first conductive film portions 2 which are electrically isolated from each other and are arranged on the rear end surface of the front substrate 1;

[0029] The rear conductive glass 200 includes a rear substrate 3 and at least two second conductive film portions 4 which are electrically isolated from each other and are arranged on the front end surface of the rear substrate 3, wherein the second conductive film portions 4 are aligned with the corresponding first conductive film portions 2;

[0030] A sealed insulating rubber frame 5 is provided between the front conductive glass 100 and the rear conductive glass 200, and the inner side of the sealed insulating rubber frame 5 is filled with an electrochromic material 6, and the electrochromic material 6 is located between the first conductive film portion 2 and the second conductive film portion 4. Specifically, when the corresponding first conductive film portion 2 and the corresponding second conductive film portion 4 are energized, the electrochromic material 6 between the energized first conductive film portion 2 and the energized second conductive film portion 4 changes color under the action of the electric field, while the electrochromic material 6 between the non-energized first conductive film portion 2 and the non-energized second conductive film portion 4 does not change color, so the zone-controlled electrochromic lens of the embodiment of the present application can control the color change of a local area separately. To be more specific, when the zone-controlled electrochromic lens of the embodiment of the present application is used in a road monitoring camera, if local overexposure occurs in the monitoring image, the first conductive film portion 2 and the second conductive film portion 4 of the corresponding overexposed area are energized separately, so that the corresponding area is discolored separately to suppress the local strong light, thereby suppressing the local overexposure in the monitoring image. The monitoring image can be partially reduced in exposure to improve the monitoring image quality, thereby solving the problem of local overexposure of the monitoring image.

[0031] like Figures 1 to 6 As shown, the first conductive film portion 2 and the second conductive film portion 4 correspond to each other one by one, and the first conductive film portion 2 and the second conductive film portion 4 are respectively distributed in sequence along the circumferential direction. In this embodiment, the first conductive film portion 2 and the second conductive film portion 4 are respectively distributed in sequence along the circumferential direction. Of course, in some embodiments, the first conductive film portion 2 and the second conductive film portion 4 are respectively distributed in sequence along the circumferential direction.

[0032] like Figures 1 to 6 As shown, the first conductive film portion 2 and the second conductive film portion 4 are both fan-shaped structures, and an electrical blocking groove 7 is provided between any adjacent first conductive film portions 2 and any adjacent second conductive film portions 4 .

[0033] like Figure 1 , 3 As shown in , 6 , the sealing insulating rubber frame 5 is arranged between the outer periphery of the front conductive glass 100 and the outer periphery of the rear conductive glass 200 .

[0034] like Figures 1 to 6 As shown, a first lug portion 8 corresponding to the first conductive film portion 2 is provided on the outer periphery of the front substrate 1, and the first conductive film portion 2 extends to the corresponding first lug portion 8 to form a first power connection portion 9;

[0035] A second lug portion 10 corresponding to the second conductive film portion 4 is provided on the outer periphery of the rear substrate 3, and the second conductive film portion 4 extends to the corresponding second lug portion 10 to form a second power connection portion 11;

[0036] The first power connection portion 9 and the second power connection portion 11 are both used to connect to a power source; specifically, the first power connection portion 9 can be used to energize the corresponding first conductive film portion 2 , and the second power connection portion 11 can be used to energize the corresponding second conductive film portion 4 .

[0037] like Figures 1 to 6 As shown, the first lug portion 8 corresponds to the first conductive film portion 2 one by one, the second lug portion 10 corresponds to the second conductive film portion 4 one by one, and the first lug portion 8 and the second lug portion 10 are staggered in the circumferential direction.

[0038] In this embodiment, the front substrate 1 and the rear substrate 3 may both be transparent glass plates, and the first conductive film portion 2 and the second conductive film portion 4 may both be ITO films.

[0039] Specifically, the front conductive glass 100 and the rear conductive glass 200 are first cut according to the required shapes. The front conductive glass 100 includes a front substrate 1, a first ITO layer is provided on the rear end surface of the front substrate 1, and the first ITO layer is laser-marked to form the electrical blocking groove 7 so that the first ITO layer is separated to form the first conductive film parts 2 that are electrically isolated from each other. Similarly, the rear conductive glass 200 includes a rear substrate 3, a second ITO layer is provided on the front end surface of the rear substrate 3, and the electrical blocking groove 7 is laser-marked on the second ITO layer so that the second ITO layer is separated to form the second conductive film parts 4 that are electrically isolated from each other, and the first conductive film parts 2 correspond to the second conductive film parts 4 one by one. A circle of sealing insulating rubber frame 5 is placed on the rear conductive glass 200 after laser marking and a liquid filling port is left. The front conductive glass 100 and the rear conductive glass 200 are bonded and cured to obtain an empty box. Then, the electrochromic material 6 is poured into the liquid filling port and the liquid filling port is sealed, thereby preparing the zone-controlled electrochromic lens of the embodiment of the present application.

[0040] In summary, when the corresponding first conductive film portion 2 and the corresponding second conductive film portion 4 are energized, the electrochromic material 6 between the energized first conductive film portion 2 and the energized second conductive film portion 4 changes color under the action of the electric field, while the electrochromic material 6 between the unenergized first conductive film portion 2 and the unenergized second conductive film portion 4 does not change color. Therefore, the partition-controlled electrochromic lens of the embodiment of the present application can independently control the color change of the local area. When the partition-controlled electrochromic lens of the embodiment of the present application is applied to a road monitoring camera, if local overexposure occurs in the monitoring image, the first conductive film portion 2 and the second conductive film portion 4 of the corresponding overexposed area are energized separately, so that the corresponding area changes color separately to suppress the local strong light, thereby suppressing the local overexposure in the monitoring image, and being able to locally reduce the exposure of the monitoring image to improve the monitoring image quality, solving the problem of local overexposure of the monitoring image.

It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention.
