Description

A kind of heavy section casting optical system of side wall addition decorative pattern
Technical field
The present invention relates to the heavy section casting optical systems of automobile lamp lighting area more particularly to a kind of side wall addition decorative pattern.
Background technique
Heavy section casting be it is a kind of light source be placed in focal point shine, light is collimated by rear wall region, then passes through front surface flower Line carries out light diffusion, reaches the new technique of uniform display effect, is widely used in civilian high-end sedan-chair, headlight, back light are all Have, be chiefly used in turn signal, daytime running lamps, position lamp, brake lamp etc., mainly uses LED light source, be increasingly becoming Automobile The main configuration of lamp.
With car light trend trend, the diversity of moulding is further important in car light field, application of the heavy section casting on car light Will more extensively, the heavy section casting of multi-functional unification also gradually captures market.The heavy section casting design of current multi-functional unification can only The light source of different function is respectively placed in defocus position, causes light entirely collimated can not enter preceding light-emitting surface, in preceding light-emitting surface The phenomenon that apparent dark space in part occur, the heavy section casting uniformity is caused to reduce.
In view of the above problems, it is solution that the heavy section casting optical system for designing new side wall texture mapping, which meets preceding luminous surface uniformity, The certainly key of problems described above.
Summary of the invention
To solve the above problems, it is an object of the invention to provide a kind of heavy section casting optical system of side wall addition decorative pattern, it will be from Burnt light source carries out reflection adjustment by side wall pattern angle by the light of side wall, realizes that again collimation is emitted in preceding light-emitting surface, It solves the problems, such as dark space, improves uniformity, solve the problems, such as to cause the reduction of the heavy section casting uniformity.
The present invention provides a kind of heavy section casting optical system of side wall addition decorative pattern, including left side light source, right side source and thickness Wall pieces are provided with side wall, preceding light-emitting surface, collimating aperture, collimating aperture side wall one, collimating aperture side wall two, the left side on the heavy section casting Side light source and the right side source are respectively positioned on the defocus position for leaving focus, wherein have side wall flower on the left side of the side wall Line one has side wall decorative pattern two on the right side of the side wall.The light that left side light source issues comes the side wall of the right side of side wall Decorative pattern two, light is by the side wall decorative pattern two adjustment light direction and preceding light-emitting surface outgoing was arrived in diffusion later;Right side source hair Light out comes the side wall decorative pattern one of the left side of side wall, and light is by the side wall decorative pattern one adjustment light direction and spreads Preceding light-emitting surface outgoing was arrived later.Light at left and right sides of collimating aperture adjusts beam projecting by side wall decorative pattern one and side wall decorative pattern two It can uniformly be incident on preceding light-emitting surface behind direction and its diffusion, solve light-emitting surface two sides dark space defect before heavy wall, improve Using the optical homogeneity of the multifunctional thick wall pieces optical system of defocus.
Further improvement lies in that the starting point of the range of the addition of the side wall decorative pattern one is one Vertical Square of collimating aperture side wall To the intersection point of extended line and side wall, side wall decorative pattern one is done forwards along side wall, final position need to be according to actual light distribution result It is determined and is adjusted;The starting point of the range of the addition of the side wall decorative pattern two is two vertical direction extended line of collimating aperture side wall With the intersection point of side wall, side wall decorative pattern two is done forwards along side wall, final position need to be determined according to actual light distribution result And adjustment.
Further improvement lies in that the design of side wall decorative pattern one is according to the light of the sending of right side source to side wall left side Angle of incident light is calculated;The design of side wall decorative pattern two is according to light the entering to side wall right side of the sending of left side light source Light angle is penetrated to be calculated.
Further improvement lies in that the width of the side wall decorative pattern one and the side wall decorative pattern two is 0.5mm-4mm.
Further improvement lies in that the left side light source can be red light source to realize taillight position lamp or taillight braking Lamp function can be white light source to realize daytime running lamps, headlight position lamp or back-up lamp function, can be the light of yellow Source is to realize turn signal function;The left side light source can be red light source to realize taillight position lamp or taillight Brake lamp function Can, can for white light source to realize daytime running lamps, headlight position lamp or back-up lamp function, can be the light source of yellow with Realize turn signal function, and the left side light source and the right side source are the light source of different colours, it is multi-functional to realize Heavy section casting optical system.
Further improvement lies in that can be controlled and be realized in the daytime by the PWM of electric current when the left side light source is white light source Switching between driving lamp and front position lamp makes optical system at this time in conjunction with the right side source that another color realizes another function Three functions may be implemented in system, and have better uniformity;When the right side source is white light source, electric current can be passed through PWM control realize the switching between daytime running lamps and front position lamp, the left side of another function is realized with another color at this time Light source combines, and makes optical system that three functions may be implemented, and have better uniformity.
Further improvement lies in that the left side light source leaves the distance of focus and the right side source leaves the distance of focus Can be identical, the side wall decorative pattern one and the side wall decorative pattern two are symmetrical relative to the central axis of the side wall at this time, design On only need mirror image;The distance that the left side light source leaves the distance of focus and the right side source leaves focus can not phase Together, the side wall decorative pattern one and the side wall decorative pattern two are asymmetric relative to the central axis of the side wall at this time, design at this time Upper needs are designed according to actual design principle.
Further improvement lies in that the material of the heavy section casting can be polymethyl methacrylate (i.e. PMMA) or poly- carbonic acid Ester (i.e. PC).
Beneficial effects of the present invention: by doing decorative pattern in heavy section casting side wall, the heavy section casting light of multi-functional unification can be improved The dark space problem that light-emitting surface occurs before the causing because of light source defocus of system improves heavy section casting show uniformity.
