Automatic sun visor for vehicle - has light sensor which determines angle of light and intensity to position sun visor

摘要

The light sensor has the sensor at the far end of a tunnel type housing. This enables it to monitor the angle of incident sunlight as well as its intensity. The light sensor is coupled to a processor which computes the optimum setting of the sun visor for the vehicle, or in the case of a sun blind over a window, in a building, to set the amount of shade required. For a vehicle the sensor is mounted at the top centre of the windscreen. The servo drive for the sun visors is mounted between the visors (7.8), which are moved along mounting tracks (10) under the roof and down part of the windscreen. ADVANTAGE - Automatic sun shade control, processor controlled.
