Document Type and Number:
WIPO Patent Application WO/2019/210668
Kind Code:
A1
Abstract:
Provided is a headlight (101). The headlight comprises a light-emitting device (102), wherein the light-emitting device (102) comprises: a first light-emitting module (104) comprising multiple first light-emitting units (106), wherein the arrangement of the multiple first light-emitting units (106) is consistent with a low beam cut-off line (107) of the headlight (101); a second light-emitting module (105) comprising multiple second light-emitting units (108). The headlight further comprises a lens (103) for projecting the light of the first light-emitting unit (106) and/or the second light-emitting unit (108). The distance between the first light-emitting unit (106) and the front focal plane (SF) of the lens (103) being less than the distance between the second light-emitting unit (108) and the front focal plane (SF) can ensure the definition of the low beam cut-off line (107) of the headlight (101) and the uniformity of light in other illumination areas of the headlight (101), and also improve the light utilization rate.
