LIGHTING SYSTEM


  1. CONSTRUCTION


    1. LED Headlights


      1. Through optimization of the shape of the lenses and reflectors inside the lights, a large illumination range has been achieved.

    2. Bi-function


      1. When low beam is selected, the light source of the high beam headlight is blocked by the shade in the headlight assembly.

      2. When high beam is selected, the shade turns so the light source of the high beam is not blocked.

      3. The bi-function is activated by the headlight ECU sub-assembly. The headlight ECU sub-assembly receives as signal to turn on the high beams from the headlight dimmer switch assembly, then activates the built-in headlight actuator to slide the shade down.

    3. LED Unit Structure for Adaptive High Beam System (Models with Adaptive High Beam System)


      1. An LED unit is provided for the adaptive high beam system.

      2. 24 LED chips for the adaptive high beam system are used to form light distribution patterns

      3. 8 LED units for the adaptive high beam system are used for the upper row and 16 LED chips are used for the lower row.

  2. OPERATION


    1. LED Unit Structure for Adaptive High Beam System (Models with Adaptive High Beam System)


      1. 24 LED chips are positioned in the LED unit for the adaptive high beam system and they are operated by the LED light control ECU.

      2. By adjusting the brightness of each LED using pulse width modulation, it is possible to optimally control the illumination area of the high beams.
