Description

Instant solar light-sensitive automatic dimming safety lens device

An instant solar light-sensing automatic dimming safety lens device, in particular to a system device for instantly generating a floating power signal by using the same lens to sense solar illuminance, and simultaneously allowing the same lens to receive a dimming signal to control the transmittance or color of the lens .

In the prior art, the known automatic dimming safety lens device system mostly produces color changes after the lens is illuminated by the light source in the environment, but because the color change speed is rather slow, the user is in a rapidly changing environment (for example, driving Or when exercising, the lens transparency or color cannot be accurately changed in real time, and the user's eyes cannot instantly reach the farthest visible distance and the most comfortable state, and the user is often in a rather dangerous state.

However, in general, the fixed color and transparency of the sunglasses often cause the user to be in a rapidly changing environment (for example, when driving or exercising), and the user cannot obtain the clearest environmental scene at any time as a great disadvantage.

In addition, the color-changing ski goggles on the market can be changed to a fixed color and illumination mode, and the color and illumination cannot be automatically changed. The skiing user cannot get the clearest picture at any time as a disadvantage.

In addition, the marketed welding mask lens assembly currently focuses on protecting the user's eyes rather than the best view.

The known translucent lenses are mainly for protecting the eyes, but often In special circumstances, users cannot be considered for safety reasons; for example, when driving in the sky, heavy rain, the driving user's line of sight is only a few meters. At present, there is no safety-oriented glasses to meet the user's requirements; In the fog zone, the driving sight is only a few meters. There is no safety-oriented eyeglass to meet the user's requirements. For example, when a driver suddenly enters the basement or tunnel, the driver can't get the clearest picture instantly. The users are often in a very dangerous state. At present, there is no glasses with the safety of this state as the main consideration to meet the user's requirements; for example, when skiing in the snow, because the current ski goggles are mainly for protecting the eyes, instead of The most clear scene is the main one, and the skiing is still in a fast-changing environment. At present, the ski goggles are designed to reduce the snow reflection and protect the eyes. The user's eyes cannot see the farthest visible distance and the clearest scene.

In view of the above, the present invention is an instant solar light-sensing automatic dimming safety lens device; wherein the lens 300 senses the solar illuminance to generate a floating power signal 201, and the dimming signal generator 200 receives the floating power signal 201 generated by the lens 300, the floating power supply The signal 201 provides the power required by the dimming signal generator 200. The dimming signal generator 200 generates a corresponding dimming signal 202 according to the floating power signal 201. The dimming signal 202 is transmitted to the lens 300 to instantly adjust the visible light source in the environment. Through the transparency or color of the lens, the farthest visible distance of the human eye is also at the same time, and the user can get the clearest environment at any time. When the user is not In the same environment (for example, rainy weather, fog, snow), the user's eyes can use this instant solar-sensing auto-dimming safety lens device to instantly reach the farthest visible distance and the most comfortable state, whether the user is driving or exercising. The clearest view and the farthest visible distance can be obtained. The user's eyes are always in a comfortable and uncomfortable state. The user is in the environment with rapid changes in the light source. The instant solar-powered automatic dimming safety lens device is used for instant, fast and accurate automatic. Adjust the illumination and color of the visible light source into the user's eyes to achieve the farthest visible distance of the human eye and at the same time, the user can get the clearest environment at any time; the user is in a strong light environment (for example: driving Or when exercising, use this instant solar-sensing auto-dimming safety lens device to instantly and accurately filter the visible light source in the excess environment, avoiding the user to be in a strong light environment to cause visual images, and instantly achieve the clearest image and the most comfortable state of the human eye. .
