ABSTRACT:
An adaptive front lighting system (AFLS) having a high heat-dissipation efficiency increases heat-dissipation efficiency of a light emitting diode (LED) to improve durability in headlamps which use LEDs as a light source and have a variable illumination angle according to conditions. The AFLS includes a lamp housing, a reflector installed in the lamp housing and rotatable around a rotational axle formed at the lamp housing, a light source installed in the reflector to emit light, an external heat sink installed at an external surface of the lamp housing so as to dissipate heat towards outside of the lamp housing, and/or a heat conduction member connecting the light source and the external heat sink so as to transfer the heat of the light source to the external heat sink. The heat conduction member is flexibly transformed in response to a movement of the reflector and the light source.
