Description

Electrochromic wearable composite lenses

The present invention relates to an electrochromic wearable composite lens, mainly referring to a lens that can change the shade of light or dark according to the brightness of the environment.

In order to protect the eyes from strong light damage, people usually wear sunglasses or helmets with dark lenses. However, although the dark lenses can reduce the light transmittance, they will cause vision loss in a weak light environment.

To improve the above situation, a color-changing agent can be coated on the surface of the lens, and the color can change according to the brightness of the environment to protect the eyes without affecting vision. However, the color-changing agent will become ineffective after a period of time and has a short service life.

Currently, an electrochromic liquid crystal layer is set in the center of the lens, and a light sensor controller and battery are set at the lens frame or lens foot outside the lens, and wires are connected to the liquid crystal layer. The light sensor can sense the brightness of the external environment and input the information into the controller to control the depth of the liquid crystal color and transmittance.

However, the PC material of the lens body with liquid crystal layer is currently manufactured by extrusion, and its thickness is about 0.2mm~0.5mm, which makes it difficult to process and coat the thinner lens to meet the UV400 standard requirement for UV protection. In addition, the strength of the lens is insufficient and it is easily damaged by collision and bending. In addition, wires must be set to connect the electrical components outside the lens, which is inconvenient to install and the appearance of the glasses does not have a complete appearance.

The object of the present invention is to provide a wearable composite lens capable of electrochromic properties and having better structural strength and integrity.

The electrochromic wearable composite lens of the present invention comprises a first lens and a second lens. The first lens comprises a first sheet and a second sheet arranged in front and back, and an electrochromic unit. The first sheet and the second sheet are arranged opposite to each other, and a space is formed in the middle. The electrochromic unit comprises two transparent conductive layers, an outer conductive gel, a liquid crystal layer, and an inductive controller. The two transparent conductive layers are respectively covered on the rear surface of the first sheet and the front surface of the second sheet. The outer conductive gel is arranged on the periphery of the first sheet and the second sheet, and the space is formed. A closed space; the liquid crystal layer is arranged at the position of the space; the inductive controller is arranged on the first sheet or the second sheet and is electrically connected to the outer conductive glue; the inductive controller has electrical energy and can sense the light brightness of the external environment, and outputs corresponding information to the outer conductive glue, the transparent conductive layer, and the liquid crystal layer, so that the liquid crystal layer can correspond to the dark or light color change action; the first sheet is provided with transparent optical glue; the second lens is arranged in front of the first lens, and has a third sheet, and the first lens is bonded and fixed to the back of the third sheet by the transparent optical glue layer.

In one embodiment of the present invention, the inductive controller has a solar panel and a control circuit, and can sense the intensity of light irradiating the solar panel to generate a corresponding amount of electric energy to be input into the control circuit, and the control circuit outputs the corresponding amount of received electric energy to the outer ring conductive gel.

An embodiment of the present invention further comprises a surface hardening layer, and the front surface of the first sheet body and the rear surface of the second sheet body are covered with the surface hardening layer.

One embodiment of the present invention further includes a multi-layer electroplating layer, and the front surface and the rear surface of the third sheet are covered with the surface hardening layer.

One embodiment of the present invention further includes a surface hardening layer, and the surface hardening layer on the front surface of the third sheet body is covered with the multi-layer film electroplating layer.

One embodiment of the present invention further comprises a water/oil repellent layer, and the water/oil repellent layer is covered in front of the multi-layer electroplated layer.

The electrochromic unit of the present invention is disposed on the first lens, which can have better integrity. The composite lens of the present invention is composited by the first lens and the second lens, which can provide the composite lens with better structural strength. The second lens is located in front of the first lens to prevent external wind, rain and foreign objects from directly impacting the electrochromic unit on the first lens, which can ensure that the electrochromic unit will not be damaged during long-term use.

When the external environment of the present invention is bright, the strong light can be projected to the inductive controller of the electrochromic unit, and the inductive controller can generate relatively large current information corresponding to the strong light and control the output to the liquid crystal layer, so that the liquid crystal layer outputs a darker color and can prevent the strong light from damaging the eyes. Conversely, when the external environment is dark, the inductive controller can receive smaller light energy and generate smaller electric energy information and control the liquid crystal layer to output a lighter color, so that the wearer can have good clarity of the first lens in darker occasions.

Please refer to Figures 1 to 4, which are partial exploded, assembled, exploded, and assembled cross-sectional views of the composite lens of the present invention, respectively. The thickness of the components in Figures 3 and 4 is for the convenience of display and does not limit the thickness of the present invention. The electrochromic wearable composite lens of the present invention includes a first lens 1 and a second lens 2. The first lens 1 includes a first sheet 11, a second sheet 12, and an electrochromic unit 13 arranged in front and back. The first sheet 11 and the second sheet 12 are arranged opposite to each other, and a space 10 is provided in the center; and the first sheet 11 and the second sheet 12 are made of transparent materials, which can be polycarbonate (PC) and can be formed by extrusion, and the front surface 111 of the first sheet 11 and the rear surface 122 of the second sheet 12 are covered with a surface hardening layer 14.

The electrochromic unit 13 includes two transparent conductive layers 131, an outer conductive gel 132, a liquid crystal layer 133, and an inductive controller 134. The two transparent conductive layers 131 are respectively covered on the rear surface 112 of the first sheet 11 and the front surface 121 of the second sheet 12. The outer conductive gel 132 is arranged around the first sheet 11 and the second sheet 12, and the space 10 is formed into a closed space. The liquid crystal layer 133 is arranged at the position of the space 10, and the outer conductive gel 132, the transparent conductive layer 131, and the liquid crystal layer 133 are electrically connected. The inductive controller 134 is arranged on the second sheet 12 and is electrically connected to the outer conductive gel 132. The sensor controller 134 has electrical energy and can sense the brightness of the light in the external environment. It can also have a solar panel and a control circuit (not shown). It can sense the intensity of the light irradiating the solar panel to generate a corresponding current size input into the control circuit. The control circuit receives the current size information and controls the output to the outer ring conductive glue 132, the transparent conductive layer 131, and the liquid crystal layer 133, and enables the liquid crystal layer 133 to change color in a dark or light manner. A transparent optical glue 15 is arranged in front of the surface hardening layer 14 of the front surface 111 of the first sheet 11.

The second lens 2 is arranged in front of the first lens 1, and has a third sheet 21. The third sheet 21 is made of a transparent material, which can be polycarbonate (PC) and can be made by injection molding. Its thickness is greater than the first and second sheets 11 and 12, and it can have better strength. The front surface 211 and the rear surface 212 of the third sheet 21 are covered with a surface hardening layer 22, and the first lens 1 is bonded and fixed to the surface hardening layer 22 of the rear surface 212 of the third sheet 21 by transparent optical adhesive 15.
