Title: Antidazzle mirror
Inventor: ONO HIROTAKA
IPC: G02F1/167
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To evade a dimming element from being fixed in an antidazzle state even when electric fault is caused. SOLUTION: In this antidazzle mirror provided with the dimming element 2 which enters a light-transmissive state when applied with a voltage from the main power source 41 and decreases in light transmissivity when applied with no voltage to enter a translucent state, the dimming element 2 is provided with a preliminary power source 46 which applies a voltage preliminarily in addition to the main power source 41. The dimming element 2 is normally in the light-transmissive state when the voltage from the main power source 41 is applied, so this mirror functions as a normal mirror which has a large reflection factor and when the voltage is not applied, the dimming element 2 enters the translucent state, so the reflection factor becomes small to provided antidazzle effect.  If the main power source 41 gets out of order, the dimming element 2 can be applied with the voltage from the preliminary power source 46. The dimming element 2 which is applied with the voltage from the preliminary power source 6 enters the light-transmissive state, so the antidazzle mirror enters a non-antidazzle state wherein the reflection factor is large.
