This relates to an energization switch that automatically turns on the power.

望まれていた。 If the crystalline lens of the eyeball is removed due to an eye disease such as cataracts, conventional glasses with fixed focal length lenses can be replaced with several types of glasses with different focal lengths depending on the distance at which they will be used. It is necessary to use them properly according to each situation, which is a great inconvenience in real life. Therefore, there has been a desire for a spectacle lens whose focal length can be freely changed. Further, the focal length of a variable focal length lens called a zoom lens used in an optical lens is controlled by changing the distance between lens groups each comprised of a plurality of single lenses. Therefore, a lens movable mechanism is essential to move the lens group, and it is difficult to fully satisfy the demands of miniaturization and low cost. It was hoped that it would appear.

よりも大きいものを正の液晶といい、逆のものは
負の液晶といわれている。 Liquid crystals generally have an elongated rod-like molecular structure with a length of several tens of angstroms and a width of about several angstroms, and they also have dielectric anisotropy, with a dielectric constant parallel to the axis of the liquid crystal molecules and a dielectric constant perpendicular to the axial direction of the liquid crystal molecules. generally do not match. A liquid crystal in which the former is larger than the latter is called a positive liquid crystal, and the opposite is called a negative liquid crystal.

連続的に変化する。 A field-effect liquid crystal with positive dielectric anisotropy is placed between two transparent electrode substrates, and when an AC voltage higher than a threshold is applied to the liquid crystal cell, which is oriented so that the liquid crystal molecules are parallel to the substrates, the liquid crystal The force acting on the dipole moment of the molecules causes the liquid crystal molecules to change the orientation of the liquid crystal molecular axes in the direction of voltage application. Therefore, depending on the magnitude of the applied voltage, the orientation of the liquid crystal molecules, which were oriented parallel to the substrate, can be continuously changed to a direction perpendicular to the substrate. Therefore, the apparent refractive index of the liquid crystal cell for incident light polarized in the orientation direction of the liquid crystal molecules changes continuously from the value for extraordinary light to the value for ordinary light.

できる。 This so-called electric field-controlled birefringence effect is determined by the relative relationship between electric energy and elastic energy, so it does not depend on the thickness of the liquid crystal cell, and it changes depending on the applied voltage rather than the applied electric field. Are known. In other words, the liquid crystal cell has a lens-like shape, and even if the thickness of the liquid crystal cell differs from place to place, optically uniform changes in the refractive index can be obtained. That is, a liquid crystal with positive dielectric anisotropy is sealed between lens-shaped substrates in which liquid crystal molecules are oriented in an appropriate direction.
By controlling the alignment direction of liquid crystal molecules using applied voltage and changing the apparent refractive index of the liquid crystal cell, the focal length of the liquid crystal lens can be adjusted to the value fe for extraordinary light.
It can be changed continuously from to the value Fo for ordinary light. When a vertically aligned liquid crystal with negative dielectric anisotropy is used, the change in focal length with respect to the applied voltage is reversed. Since the alignment state of liquid crystal molecules can be changed by applying a magnetic field instead of applying a voltage, it is also possible to create a variable focal length lens using a magnetic field.

る。 There are also sunglasses that use liquid crystals or EC elements, but these use elements in the lens portion that change color or light transmittance when external voltage is applied. Here, electrochromism (EC)
The phenomenon is a phenomenon in which color or light transmittance changes reversibly due to an oxidation/reduction reaction that occurs at or near an electrode surface when a voltage is applied to a substance. Examples of materials that significantly exhibit this phenomenon include viologen salts and tungsten oxide. In particular, by using a material in which tungsten trioxide (WO 3 ) is mixed with molybdenum trioxide (MOO 3 ) or vanadium pentoxide (V 2 O 5 ), elements exhibiting various colors can be provided. Furthermore, if an element is used in which a material that colors and a material that decolors when a voltage is applied is used, the color can be changed continuously. Furthermore, if colored glass or the like is used, the color of the entire lens portion can be changed.

Therefore, it is desirable to use a booster circuit in view of battery space, weight, etc.
Since this booster circuit has relatively large power consumption, it is necessary to prevent unnecessary power consumption by preventing forgetting to turn off the power switch. In addition, in the EC element,
Since a certain amount of current also flows through the element during operation,
It is extremely important to prevent wasteful power consumption. It is conceivable to install this power switch on the temple of the glasses, but it is unavoidable to forget to turn it off when not in use, and it is also possible to provide a power switch in conjunction with the folding operation of the temple, but when the temple is unfolded. There was a problem with the power not turning off when it was placed on a desk.
