Abstract
Description
[Technical field]
[0001] The invention relates to the technical field of optical lenses, in particular to an anti-sunset backlight lens for reducing visual light harm caused by the oblique rays of the setting sun. [Background technology]
[0002] When the sun sets, the oblique rays of the setting sun will not only produce a large amount of low color temperature red light, but also be disturbed by the ambient air and suspended particles, causing the setting sun to produce multi-directional refraction and polarized light. If a person driving or watching a screen in an environment with setting sun backlight is wearing glasses equipped with fully polarized lenses, the 100% polarization of the lenses will easily affect the aforementioned red light, multi-directional refraction and polarized light, resulting in poor image contrast or color discrimination errors, image aberrations and rainbow phenomena, and even blurred images.
[0003] Therefore, how to design an anti-sunset backlight lens that can improve the above-mentioned problems is a topic that needs to be solved urgently. [Utility Model Content]
[0004] The invention provides an anti-sunset backlight lens for reducing visual light harm caused by the oblique rays of the setting sun.
[0005] The anti-sunset backlight lens of the present invention includes a polarized lens and an optical coating. The polarized lens provides a polarization effect of 40% to 60%. The optical coating is formed on the incident surface of the polarized lens, and the optical coating includes a base structure and an adjustment structure. The base structure is stacked on the incident surface, and the adjustment structure is stacked on the base structure. The base structure includes a plurality of silicon dioxide layers stacked one by one, and the adjustment structure includes a plurality of titanium pentoxide layers and a plurality of silicon dioxide layers stacked alternately. Accordingly, the anti-sunset backlight lens of the present invention utilizes a low-polarized lens in combination with a coating design, which can block a large amount of red light when the setting sun is oblique, and does not affect color discrimination and visual clarity, and is not prone to black screen or rainbow phenomena caused by aberrations for drivers and screen viewers.
[0006] In one embodiment of the present invention, the polarized lens is treated with color addition and tinting, and is combined with an optical coating so that the anti-sunset backlight lens maintains an average light transmittance of less than 10% for incident light in the wavelength range between 600 nanometers (nm) and 700 nanometers (nm), and maintains an average light transmittance of more than 10% for incident light in the wavelength range between 400 nanometers (nm) and 600 nanometers (nm).
[0007] In one embodiment of the present invention, after the polarized lens is processed by color addition and tinting, the transmittance of the polarized lens to the incident light in the wavelength range between 600 nanometers (nm) and 700 nanometers (nm) is 27.79% to 68.83%, and the transmittance of the polarized lens to the incident light in the wavelength range between 410 nanometers (nm) and 600 nanometers (nm) is 3.44% to 27.29%.
[0008] In one embodiment of the present invention, the anti-sunset backlight lens has a light transmittance of 15.98% to 5.03% for the wavelength range of incident light between 600 nanometers (nm) and 700 nanometers (nm), and a light transmittance of 1.40% to 15.98% for the wavelength range of incident light between 400 nanometers (nm) and 600 nanometers (nm).
[0009] In one embodiment of the present invention, the total number of stacked layers of the multiple silicon dioxide layers of the base structure is 5 layers.
[0010] In one embodiment of the present invention, the total number of stacked layers of the plurality of titanium pentoxide layers and the plurality of silicon dioxide layers in the structure is adjusted to be 10 layers.
[0011] In one embodiment of the present invention, the polarized lens can provide a 50% polarization effect.
[0012] Accordingly, the anti-sunset backlight lens of this invention utilizes polarized lenses with polarization effect in combination with designed optical coatings to filter the incident light of the sunset into single-direction polarized light, and adjust the light penetration spectrum of the lens to provide the effect of blocking red light without affecting color discrimination and visual clarity, and complies with international specifications and standards.

For example, a component or structure comprising a plurality of elements is not limited to only those elements listed herein, but may include other elements that are not expressly listed but are generally inherent to the component or structure.
[0031] Please refer to Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of the structure of the anti-sunset backlight lens created for this project. Figure 2 This is a partial structural diagram of the anti-sunset backlight lens created for this project. Figure 1As shown, the anti-sunset backlight lens 1 of the present invention includes a polarized lens 10 and an optical coating 20. The polarized lens 10 is a low-polarized lens with a polarization effect, which is used to filter the incident light passing through the incident surface into a single-direction polarized light. In the present invention, the polarized lens 10 is designed to provide a polarization effect (polarization degree) of 40% to 60%, which can effectively reduce the black screen or rainbow phenomenon caused by the aberration generated when watching the screen compared to the full polarized lens. In a preferred embodiment of the present invention, the polarized lens 10 can provide a 50% polarization effect.
[0032] In the present invention, the polarized lens 10 is processed by color addition and color adjustment, thereby adjusting the light transmission spectrum of the polarized lens 10 to cope with the sunset backlight environment. The design of adjusting the light transmission spectrum of the polarized lens 10 will be described in the following embodiments.
[0033] like Figure 1 and Figure 2 As shown, the optical coating 20 is formed on the incident surface 11 of the polarized lens 10, and the optical coating 20 is used to reduce the phenomenon of image contrast degradation caused by a large amount of low color temperature red light in the sunset backlight, and cooperate with the polarized lens 10 to provide a further adjustment effect of the light penetration spectrum. The optical coating 20 includes a base structure 21 and an adjustment structure 22. The base structure 21 is formed on the incident surface 11 of the polarized lens 10. The base structure 21 includes a plurality of silicon dioxide (SiO2) layers 211, and the plurality of silicon dioxide layers 211 are stacked one by one to form the base structure 21, so as to ensure that the base structure 21 is not easily damaged by high temperature when the adjustment structure 22 is subsequently formed. In one embodiment of the present invention, the total number of stacked layers of the plurality of silicon dioxide layers 211 of the base structure 21 is 5 layers, but the present invention is not limited thereto.
[0034] The adjustment structure 22 is formed on the side opposite to the incident surface 11 of the polarized lens 10 connected to the base structure 21; that is, the base structure 21 is located between the incident surface 11 of the polarized lens 10 and the adjustment structure 22. The adjustment structure 22 includes a plurality of titanium pentoxide (Ti3O5) layers 221 and a plurality of silicon dioxide layers 222, and the plurality of titanium pentoxide layers 221 and the plurality of silicon dioxide layers 222 are stacked alternately one by one to form the adjustment structure 22; that is, in the present invention, any titanium pentoxide layer 221 of the adjustment structure 22 will not contact another titanium pentoxide layer 221, and any silicon dioxide layer 222 of the adjustment structure 22 will not contact another silicon dioxide layer 222. In one embodiment of the present invention, the total number of stacked layers of the multiple titanium pentoxide layers 221 and the multiple silicon dioxide layers 222 of the adjustment structure 22 is 10 layers, that is, the adjustment structure 22 includes 5 layers of titanium pentoxide layers 221 and 5 layers of silicon dioxide layers 222, but the present invention is not limited thereto.
[0035] The polarized lens 10 of the anti-sunset backlight lens 1 of the present invention is processed by adding color and adjusting the color tone, and is matched with the setting of the optical coating 20, so that the light transmittance of the final anti-sunset backlight lens 1 for the incident light in the wavelength range between 600 nanometers (nm) and 700 nanometers (nm) (i.e., the red light wavelength range) is maintained at an average of less than 10%, and the light transmittance of the incident light in the wavelength range between 400 nanometers (nm) and 600 nanometers (nm) is maintained at an average of more than 10%. Accordingly, after the anti-sunset backlight lens 1 of the present invention uses the polarized lens 10 in combination with the optical coating 20 to achieve the effect of adjusting the light transmission spectrum, it will provide users with a considerable degree of visual clarity when wearing it, and can meet the international standards of different sunglass lenses such as the US FDA, New Zealand, Australia and the European Union.
[0036] Please refer to Figure 3 This is a schematic diagram of the light penetration spectrum of the polarized lens after adding color and adjusting the color tone of the sunset backlight protection lens created for this project. Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the polarized lens 10 of the anti-sunset backlight lens 1 of the present invention is processed by adding color and adjusting the color tone, so that the light transmittance of the polarized lens 10 itself in the wavelength range between 600 nanometers (nm) and 700 nanometers (nm) in the incident light is adjusted to 27.79% to 68.83%, and the light transmittance of the aforementioned wavelength range is 41.82% on average; furthermore, the light transmittance of the polarized lens 10 in the wavelength range between 410 nanometers (nm) and 600 nanometers (nm) in the incident light is adjusted to 3.44% to 27.29%, and the light transmittance of the aforementioned wavelength range is 19.63% on average. Figure 3 The detailed values of the light transmittance of the light transmittance spectrum shown in the figure can be found in Table 1 below.

[0038]
[0039] Please refer to Figure 4 This is a schematic diagram of the light penetration spectrum corresponding to the anti-sunset backlight lens created for this project using polarized lenses combined with optical coatings. Figure 1 and Figure 4As shown, in one embodiment of the present invention, the polarized lens 10 of the anti-sunset backlight lens 1 of the present invention is subjected to the aforementioned color addition and color adjustment treatment, and is combined with the setting of the optical coating 20, so that the light transmittance of the overall anti-sunset backlight lens 1 in the wavelength range between 600 nanometers (nm) and 700 nanometers (nm) of the incident light is adjusted to 15.98% to 5.03%, and the light transmittance of the aforementioned wavelength range is 8.75% on average; furthermore, the light transmittance of the overall anti-sunset backlight lens 1 in the wavelength range between 400 nanometers (nm) and 600 nanometers (nm) of the incident light is adjusted to 1.40% to 15.98%, and the light transmittance of the aforementioned wavelength range is 13.25% on average. Figure 4 The detailed values of the light transmittance of the light transmittance spectrum shown in FIG. 2 can be referred to in the following Table 2.

[0042]
[0043] Accordingly, the anti-sunset backlight lens 1 of the present invention uses the polarized lens 10 processed with color addition and color adjustment in combination with the optical coating 20 to adjust the light penetration spectrum corresponding to the overall anti-sunset backlight lens 1. This allows the anti-sunset backlight lens 1 of the present invention to block a large amount of red light when the setting sun is obliquely shining in a setting sun backlight environment without affecting color discrimination and maintaining visual clarity.
[0044] In addition, in the present invention, the optical coating 20 is formed on the incident surface 11 of the polarized lens 10 by electroplating using an electroplating target of a corresponding material. In one embodiment of the present invention, the polarized lens 10 and the electroplating target of a corresponding material can be placed in an environment with a temperature of 5×10 -4 In a vacuum electroplating environment of 1.50 Pa, an ion-assisted deposition film-forming method is used to perform an electroplating process on the incident surface 11 of the polarized lens 10, thereby forming an optical coating 20. The optical coating 20 formed by the aforementioned method can increase the adhesion and hardness of multi-layer electroplating. Among them, silicon dioxide (SiO2) is first used as an electroplating target to form a base structure 21 of the optical coating 20, and then titanium pentoxide (Ti3O5) and silicon dioxide (SiO2) are used as electroplating targets for alternate electroplating to form an adjustment structure 22 of the optical coating 20, and finally the overall optical coating 20 is formed.
[0045] In one embodiment of the present invention, a cryogenic freezing pump can be configured in the aforementioned vacuum electroplating environment. Since the total number of stacked layers of the optical coating 20 is as high as 15 layers in the electroplating process, the material will release water molecules or material waste gas due to the high temperature of the environment, resulting in the coating effect and material adhesion being affected. Therefore, a cryogenic freezing pump is used to provide a condensation adsorption effect on water molecules or material waste gas in the vacuum electroplating environment, so that the water molecules or material waste gas are inert, and the coating adhesion is maintained in the vacuum state of the environment, so as to achieve the aforementioned light penetration spectrum adjustment requirements.
[0046] The above embodiments are essentially only auxiliary explanations, and are not intended to limit the application target of the embodiment or the application or use of multiple embodiments.

On the contrary, the aforementioned embodiments will provide a simple guide for those with common knowledge in the art to implement one or more of the embodiments described. Furthermore, various changes can be made to the functions and arrangements of the components without departing from the scope defined by the claims, and the claims include known equivalents and all foreseeable equivalents when the present patent application is filed.
