The purpose of the utility model is to provide one kind to realize multi-functional heavy wall Light-guiding optics system by broadening, includes Heavy wall light guide, heavy wall light guide rear portion are provided with a collimating structure at the top of each step in step-like；The heavy wall of each step Light guide rear end is heavy wall Light-guiding optics decorative pattern two, is heavy wall Light-guiding optics decorative pattern one, heavy wall on the right side of heavy wall Light-guiding optics decorative pattern two Heavy wall Light-guiding optics decorative pattern four is provided on the collimating structure at two top of Light-guiding optics decorative pattern；Heavy wall light guide front end is heavy wall Light-guiding optics decorative pattern three；It is one group per two adjacent steps, is respectively arranged with one He of LED light source above one group of two step LED light source two；LED light source two does not light LED light source when LED light source two is lighted when LED light source one is lighted One does not light.
Further improvement lies in that: the light that the LED light source one or LED light source two issue is entered thick by optical patterns four Wall light guide is collimated in vertical direction, and light comes optical patterns face two, and the change direction of propagation is horizontal direction, optics flower Optical patterns on line two, light is broken up, and increases light propagation width in the horizontal direction.
Further improvement lies in that: a part propagates to the light of side wall by optical patterns one, and light is broken up to progress to the right Diffusion increases the light in the collimating structure region being folded at the LED light source that right side is not lit, further increase horizontal direction Broadening.
Further improvement lies in that: the LED light source one is white light source or yellow light sources or red light source；It is described LED light source two is white light source or yellow light sources or red light source；The LED light source one and LED light source two be not using With the LED light source of color；The optical system is set to can be realized simultaneously multiple and different functions.The LED light source one uses yellow LED light source individually lights the LED light source one and realizes that turning function, the LED light source two use White LED light source, individually It lights the LED light source two and realizes daytime running lamps function, controlled by PWM, the white LED light source two is able to achieve position Lamp function is set, is realized with this and is lighted the same area is multi-functional.
Further improvement lies in that: the LED light source one and LED light source two share pcb board, keep pcb board and heavy wall light guide whole Body takes up space smaller.
Further improvement lies in that: heavy wall Light-guiding optics decorative pattern three is the decorative pattern of small cube shape, makes multi-functional to light Shi Yougeng Good lights effect.
Further improvement lies in that: the heavy wall light-guide material is polymethyl methacrylate or polycarbonate.
The utility model has the beneficial effects that the utility model realizes different function by adjacent LED light source, a kind of function is lighted When the LED light source of energy, the LED light source of adjacent another function is not lighted, and lights two collimations by single LED light source Structural region realizes multi-functional heavy wall Light-guiding optics system；Pass through heavy wall Light-guiding optics decorative pattern one and heavy wall Light-guiding optics flower The diffusion of line two and broadening function realize uniformly lighting for entire multi-functional heavy wall Light-guiding optics system.
