Reading lamp system for passengers especially in an aircraft |
摘要 |
A reading lamp system for passengers especially in an aircraft is equipped with at least one central light source preferably including a cool light lamp, the light of which is supplied through light guides such as fiber optical conductors, to individual reading lamps having a housing to which the respective light guide is connected. A liquid crystal film is positioned in the lamp housing between the light exit of the respective light guide and a lens that provides a light output from the reading lamp housing. The liquid crystal film is controllable in its light transparency by a passenger through a switch, whereby the passenger can make the liquid crystal film opaque to switch off the reading lamp or transparent to switch on the lamp. A dimmer may also be arranged to provide intermediate light level illuminations.
