Title: Method for preventing influence of sunlight and the like in signal light
Inventor: FUJIKI AKIYOSHI
IPC: G02F1/13
Filed: 1994-10-13
Abstract: PURPOSE: To enable a signal light to provide correct and distinct information by arranging a liquid crystal film at the signal light and synchronizing the turning-on/off of the signal light with the transparentness/opaqueness of the liquid crystal film. CONSTITUTION: The liquid crystal film 5 is arranged on the front surface of the signal light. The film 5 is connected to the power source 6 of the signal light by a relay 7 in order to synchronize the film 5 with the electric bulb 2 of the signal light. There is an arranging method such as combination to laminated glass, etc., concerning the liquid crystal film 5. Then, the film 5 becomes opaque in an frosted glass state at the time of turning-off the signal light so that sunlight is scattered by the film 5. Therefore, the indistinct state owing to the reflection light of the sunlight from the signal light inside does not occur and a surface becomes the frosted glass state so that turning-off comes to be distictly clear. Moreover, the film 5 becomes the transparent state at the time of turning-on the signal light so that the sunlight passes through the liquid crystal film 5.  Therefore, the sunlight is reflected inside the signal light and comes outside. Light generated from the light source of the signal light is simultaneously comes outside in the normal state.
