There was a problem of giving a stimulus: In view of this problem, it has been proposed to use feedback control to keep the amount of light passing through the lens constant. It is necessary to measure the light intensity using a sensor, and the control circuit becomes complicated. In particular, this control method causes an increase in the number of parts and an increase in weight, and It has when it comes to up and there is a serious problem, but the appearance of prescription sunglasses which have a function of a concave lens or a convex lens has been desired, the liquid crystal sunglasses for chromatic this檨feature were not present ÷

Are arranged so that the phases are opposite to each other, because when a DC voltage is applied, electrolysis occurs near the electrodes. Next, the liquid crystal cell-810 of this embodiment is constructed. The selection of the physical properties of the liquid crystal material to be used is explained .. The liquid crystal sunglasses 600 of this embodiment can be used even if the light intensity A of the light beam incident on the lens portions 62, 62 changes. It is desirable that the transmitted light positions of the sections 620 and 620 be constant at the optimum light intensity. That is, in order to reduce the stimulus to the human eye, the light intensity A of the incident light beam changes. However, it is desirable that the transmitted light i of the lens sections 620 and 620 has the optimum light intensity B. In this embodiment, the optimum light intensity B is 2 , 00 / Lex .: That is, the light intensity of the incident light A and the light intensity that enters the user's eye after passing through the lens portions 6200 and 6200 according to the light intensity A The liquid crystal sunglasses 600 in which B is 2 000 lux will be described: First, the light intensity A of the light beam incident on the lens sections 6200 and 6200, and the driving circuit 8 for this light intensity A The relationship between 0 and the voltage V applied to the liquid crystal cell-810 is determined by experiment, and a graph as shown in Fig. 8 is created. That is, the horizontal axis in Fig. 8 is the light intensity A The vertical axis represents the voltage applied to the liquid crystal cell 8100 at the light intensity A. Here, the light intensity A of the light に incident on the lens portions 6200 and 6200 is 10 , 000 lux, we can read the corresponding applied voltage V: ie, 10, 000 / lex, then V = VA. Incident light 1 1 0, 1 1 0 In order to reach the optimal light intensity B (2,000 lex in this explanation), set the transmittance to Β, 'A = 2.000,-1 0. 000 = 0.2 It is necessary (transmittance 0.2 = 20%). Therefore, as shown in Fig. 9, the vertical axis shows the transmittance, and the horizontal axis shows the applied voltage V to the liquid crystal cell -810. , V = V で, it is possible to adjust the transmittance to 20%. Similarly, from Fig. 8, multiple light intensities A of other incident light are read, and the transmittance of each is calculated. By plotting in Fig. 9, a graph showing the relationship between transmittance and applied voltage V can be obtained.
次に， 液晶セル 8 1 0には、 一対の懾光子が形成されており、 こ れらの懾光子の透過率には、 最大透過率と最小透過率が存在する： 言い替えれば、 液晶が透過率を変化させても、 その変化範囲を規制 するものである 本実施例の液晶セル-の懾光子の最大透過率は 2 5 % ( 0.2 5 ) であり， 最小透過率は 7 % ( 0.07 ) であるので、 それぞれの透過率に対応する場合に， 液晶セ - 8 1 0に印加される 電圧 Vを第 9図から読み取ることができる： 即ち， 最大透過率 （ 2 % ) に対応する電圧を V 1とし、 最小透過率 （ 7 % ) に対応する 電圧を V 2とする：. そして、 液晶セル' 8 1 0を構成する液晶素材 特性値を， しきい値電圧については V 1と同電圧に設定し、 飽和電 圧については V 2と同電圧に設定すれば、 入射光緣の光強度 ΑίΠ変 化に鬨係することなく、 レンズ部 620、 6 20を通過する光強度 を最適光強度 Β 【本説明では， 2、 000 /レクス） に一定にするこ とができる . なお、 最適光強 ¾Βであるが、 本説明では 2、 004- クスを採用しているが， このデータは、 日本色彩字会耩 色彩化字 ハンドブックによるものである .:. このため最適光強度 2 、 0 0 0ル- クスが， 本実施例の液晶サングラスに最適であるという理論は確立 しておらず、 使用者によって変化する可能性がある .， 従って， 本明 細書における最適光強度 Bとは， 任意に定められた光強度であれば 足りる .:. ここで、 ί霄光子の最大透過率と最小透過率とは、 iff光子の 特性によって変化するものである， したがって， 最小透過率が低く、 最大透過率の大きい罱光子を採用すれば、 入射光線の光強度 Aの対 応範囲が広いサングラスを提供することができる Next, a pair of photons is formed in the liquid crystal cell 8100, and the transmittance of these photons has a maximum transmittance and a minimum transmittance: in other words, the liquid crystal transmits Even if the transmittance is changed, the range of change is regulated. The maximum transmittance of the liquid crystal cell of this embodiment is 25% (0.25), and the minimum transmittance is 7% (0.07). Therefore, for each transmittance, the voltage V applied to the liquid crystal cell -810 can be read from Fig. 9. That is, the voltage corresponding to the maximum transmittance (2%) can be calculated as follows. Let V1 be the voltage corresponding to the minimum transmittance (7%): V2: Then, the characteristic value of the liquid crystal material constituting the liquid crystal cell '810 is the same as the threshold voltage of V1 If the saturation voltage is set to the same voltage as V2, the light intensity of the incident light 緣 will not be affected by the change The light intensity passing through the lens units 620 and 620 can be kept constant at the optimum light intensity Β [in the present description, 2,000 / lex). The optimum light intensity ¾Β is 2 in this description. , 004- This data is based on the Handbook of Colorized Characters by the Japan Colored Characters Association .: For this reason, the optimal light intensity of 2000lux was applied to the liquid crystal sunglasses of this example. The theory of optimality has not been established, and may vary depending on the user. Therefore, the optimal light intensity B in this specification is sufficient if it is arbitrarily determined. Here, the maximum transmittance and the minimum transmittance of the Xiao photon change depending on the characteristics of the iff photon. Therefore, if the minimum transmittance is low and the maximum transmittance is large, the incident light is Can provide sunglasses with a wide range of light intensity A
なお、 上記の方式で設定された液晶素材のしきい値電圧及び飽和 電圧が、 駆動回路 8 0 0に対して低くすぎる場合がある， この場合 には、 本実施例の様に駆動回路 8 0 0と液晶セル 8 1 0との間に分 圧コンデンサ 8 2 0を挿入し、 液晶セル 8 1 0の両端部に、 分割電 圧が印加される様に構成する必要がある . この様に構成された実施 例では、 液晶セル · 8 1 0の動作点をシフ 卜させることができるとい う効果がある なお、 分圧コンデンサ 8 2 0の代わりに分圧抵抗 8 4 0を接続することもできる この場合には， 分圧コンデンサ 8 2 0の方が、 消費電力の低い点で ftれていると思われる .  In some cases, the threshold voltage and the saturation voltage of the liquid crystal material set by the above method are too low with respect to the driving circuit 800. In this case, the driving circuit 800 is used as in this embodiment. It is necessary to insert a voltage dividing capacitor 820 between the liquid crystal cell 810 and the liquid crystal cell 810 so that the divided voltage is applied to both ends of the liquid crystal cell 810. In this embodiment, there is an effect that the operating point of the liquid crystal cell 8100 can be shifted.A voltage dividing resistor 8400 may be connected instead of the voltage dividing capacitor 820. In this case, it seems that the voltage dividing capacitor 820 is shifted ft in terms of lower power consumption.

Also, the focal length of the liquid crystal lens 1200 is the combined focal length of the transparent substrate 1 210 and the focal length of the liquid crystal material 1 220. Distance: Here, if the combined focal length is positive, it becomes a convex lens, and if it is negative, it becomes a concave lens: Therefore, the refractive index of the transparent substrate 1 210 is If it is made of a material having a value larger than the refractive index for ordinary light 小 さ い and smaller than the refractive index for extraordinary light, the TN liquid crystal cell It is possible to switch between a concave lens and a convex lens by applying a certain voltage: Therefore, it is possible to easily manufacture bifocal sunglasses. Since there is no need to increase the light transmittance of the lens section 100, the lens should be a near lens. In addition, when the mourner sees far away, it is often outdoors.
