1d, the mould group integrated functionality light-emitting surface 1d are set as several irregular small curved surfaces.
Further, the light-emitting surface of mould group integrated functionality and the light-emitting surface of the mould group function of tonic chord share, the front end of the lens 1
Face is smooth convex lens curved surface.
Further, the light-emitting surface of the lens 1 in the longitudinal direction with the mould group integrated functionality light-entry structure 1b
Corresponding region is provided with local microstructural, which is the cambered surface of convex or concave or the graininess knot arbitrarily arranged
Structure.
The beneficial effects of the present invention are:
1) integration degree is high for car light mould group, and relative cost is low, because setting condenser to the main function of car light mould group
Can first order optics element, secondary optical elements of the lens as car light mould group, and by the optical texture and lens of integrated functionality
Setting is structure as a whole, so that the optical property of car light mould group improves, the mainly raising of optical efficiency and functional diversities, this
It is due to the first order optics element as the function of tonic chord, condenser is high compared to the optical efficiency of reflecting mirror；
2) car light mould group more minimizes because by the optical texture of other function (such as DRL, corner lamp, position lamp) and
Lens setting is integrated, and makes full use of the optical space of car light mould group；
3) set the shape bent up and down for function of tonic chord condenser, can substantially shorten car light mould group length direction away from
From so that the volume of car light mould group is more compact.
