  • Dual light path forming type projection optical system and head lamp and vehicle to which the same optical system is applied
    Patent number: 10259380
    Abstract: A dual light path forming type projection optical system may include a reflector allowing light generated from a light source to be formed into a lower reflecting light reflected to an upward path directing upward and an upper reflecting light reflected to a downward path directing downward, a prism lens allowing the upper reflecting light to be emitted as a prism low beam in which the downward path is changed into the upward path and allowing the prism low beam to be changed into a prism high beam by changing an incident angle of the upper reflecting light, and an aspheric lens for generating a low beam by allowing the prism low beam to be added to the lower reflecting light and generating a high beam by allowing the prism high beam to be added to the lower reflecting light.
