Description
Technical field
The present invention relates to the field of optical systems designed applied to automobile tail light, more particularly to one kind to imitate with light curtain atom
The automobile tail light of fruit.
Background technology
, can be in strict conformity with the premise of regulation in the car light for meeting to design with making rapid progress for automobile lamp technology development
Under, vehicle client to the appearance of car light, also increasingly pay attention to by the size of overall compact and light-emitting area.Current car tail
In addition to using common bulb as light source, more and more lamps select to be used as light source by the use of LED lamp.LED is selected to come pair as light source
Lens are designed, it is possible to achieve a variety of moulding, and the utilization to space also has the choice of bigger.Heavy wall is molded by 2K
The reference of part, then the selection of cooperated with LED light source, can form the effect of light curtain and the brightness of ladder, realize unexpected effect
Fruit.In addition, the position for the design cooperated with LED light source for passing through light guide is put, interior in a limited space vehicle can be better met
The requirement of client.
The content of the invention
To solve the above-mentioned problems, the object of the present invention is to provide a kind of automobile tail light with light curtain atom effect, lead to
Cross and usually require to select common LED light source using with the automobile tail light of light curtain atom effect, with the use of light guide and
It is a kind of to collect diffusing reflection, total reflection and diffusion and the heavy section casting of one, so as to fulfill light curtain effect and the effect of ladder brightness.
The present invention provides a kind of automobile tail light with light curtain atom effect, including the LED light source on pcb board,
Light guide, 2K injection heavy section castings, the LED light source are installed on light guide side, and wherein 2K injection heavy section castings are divided into transparent part and in vain
Color part, transparent part include 2K heavy section castings transparent part and 2K heavy section casting light curtain transparent parts, wherein 2K heavy section castings hyalomere
A point part is 2K heavy section casting transparent part optical patterns face；White portion is divided into 2K heavy section castings white portion and 2K heavy section casting light
Curtain white portion, LED light source are coupled into after light guide and are uniformly incident to the rear surface of 2K injection heavy section castings in light guide front surface, enter
The light of 2K heavy section casting transparent parts is propagated in 2K injection heavy section castings, and diffusing reflection occurs in 2K heavy section castings white portion so that
Most of light is projected by 2K heavy section casting transparent part optical patterns face, and another part enters the 2K heavy section castings of heavy section casting lower part
Light curtain transparent part, to be formed by being emitted after 2K heavy section casting light curtain white portion diffusing reflections from 2K heavy section casting light curtain transparent parts
The light curtain of uniform luminance.
Further improvement lies in that：The LED light source enter light guide after when, it may occur that total reflection, obtain approximately parallel light
Line enters heavy section casting.
Further improvement lies in that：The rear surface of the 2K heavy section castings transparent part is parallel with the dentalation face of light guide, makes
The light just related to by light guide can improve positive uniformity evenly into 2K heavy section casting transparent parts.
Further improvement lies in that：There is the white structure of double-shot moulding in the bottom surface of the 2K heavy section castings transparent part, makes heavy wall
Light in part propagates to the light curtain region of heavy section casting by the way that diffusing reflection occurs after white structure.
Light guide entrance face is positioned over using LED light source, after being coupled into light guide, after the outgoing of light guide front enters heavy section casting
Surface.Diffusing reflection can occur after white portion is touched in heavy section casting by the light of rear surface into heavy section casting, pass through control
The ratio of heavy section casting length and height processed makes light to pass through table before heavy section casting into the light curtain part of heavy section casting, most of light
The optical patterns in face are emitted to form the light curtain that a brighter light belt another part enters heavy section casting lower part, by white in heavy section casting
From front, outgoing forms the light curtain of uniform luminance after color part diffusing reflection.Three primary focus of the present invention：First, LED is sent
Light be coupled into light guide after, enable more light from light guide front uniform.Second, the front surface of heavy section casting is use up
It is possible to optimize, more light is emitted by front and form a brighter uniform light belt.Third, to heavy section casting
Optical patterns be adjusted on demand, optical patterns can be such that light is preferably diffused, and meet outside in position lamp function
The demand of angle of visibility.
Beneficial effects of the present invention：By using common LED light source, pcb board, the heavy section casting of double-shot moulding, light guide, pass through
Reasonable placement and heavy section casting bottom surface, front, integrally-built design to LED and light guide, enable one piece of special-shaped heavy section casting
Completely sufficiently it is lit, so as to reach the position lamp function of light curtain atom, ladder brightness；The optical surface of light guide and heavy section casting
Rear surface is parallel, enable light that LED light source launches efficiently, be equably coupled into heavy section casting and propagated；Heavy section casting bottom
There is the white structure of double-shot moulding in face, the light in heavy section casting is propagated to thickness by the way that diffusing reflection occurs after white structure
The light curtain region of wall pieces；The positive optical patterns of heavy section casting, spread the positive light of arrival heavy section casting, effectively control light
The range of scatter and angle of line.
