Patent number: 9201504Abstract: The present invention provides a vehicular glance lighting apparatus which provides a driver with vehicle-running information as light of a background screen and includes a driver attention function through prompt information delivery such that the driver visually recognizes as a background screen the vehicle-running information needed essentially or minimally for running the vehicle without requiring the driver's attention to avoid dissipation of the driver's sight, thereby preventing the driver's driving attention from being diverted, and a method for controlling the same. The vehicle-running information related with the running of a vehicle to be outputted in the form of light as a background screen, so that a driver can perceive the vehicle-running information without diverting or obstructing the driver's driving attention, thereby enhancing the driver's ability to cope with a vehicle travel risk during the traveling of the vehicle.Type: GrantFiled: April 27, 2012Date of Patent: December 1, 2015Assignee: DAESUNG ELECTRIC CO., LTD.Inventors: Jun-Ho Gohng, Dae Woo Kwon, Moon Soo Park, Chang Kyu Han
