Abstract (en)
[origin: EP3848626A1] The present invention relates to the field of automotive front-lighting, and particularly to a front-lighting system for a vehicle. The front-lighting system comprises a light source (10) and an integrated lens (20). The integrated lens (20) comprises a light entrance surface (21, 21'), a light exit surface (23, 23'), and a light guiding portion (22) sandwiched between the light entrance surface (21, 21') and the light exit surface (23, 23'). The light source (10) is configured to emit a first light beam and a second light beam onto the light entrance surface (21, 21'). The light guiding portion (22) is configured to receive the first light beam and the second light beam from the light entrance surface (21, 21'), and guide them towards the light exit surface (23, 23'), where the first light beam and the second light beam are both redirected out from the integrated lens (20). The light guiding portion (22) comprises at least a first notch (221) and a second notch (222) opposite to the first notch (221), wherein, while being guided, the first light beam undergoes an at least partial reflection successively by the first notch (221) and the second notch (222), and the second light beam undergoes a refraction by the second notch (222).
