Abstract
It is an object of the invention to provide a kind of projection-type headlamp optical system, by adding a triangular prismatic type lens on the outside of dead line light barrier, triangular prismatic type lens sizes are millimeter rank, triangular prismatic type lens moulding follows dead line light barrier, and therewith into certain inclination angle, when not adding triangular prismatic type lens, from the top through the white light of dead line baffle plate, can occur dispersion at dead line, based on blue light；Now, install additional with the triangular prismatic type lens at certain inclination angle, make by the optical dispersion of triangular prismatic type lens into based on feux rouges and appearing near dead line on the outside of dead line baffle plate；Finally the cut-off Line beam based on blue light and the beam combination based on feux rouges, show the dead line of white；Compared with conventional method, the present invention can weaken dispersion phenomenon, at the same again will not sacrificial system efficiency, improve light efficiency.
Description
Technical field
The present invention relates to automobile lamp headlamp field, more particularly to a kind of projection-type headlamp optical system.
Background technology
No matter in which country car headlamp regulation, for dipped beam there is clear and definite "cut-off"line to provide.Cut
Only the setting of line can allow driver preferably to observe road conditions in the outside of direction of traffic, while in the inner side of direction of traffic（I.e.
Opposite meeting side）The irradiation to opposite drivers and pedestrians is reduced, so as to protect pedestrian on the driving safety and road of opposite car
Safety."cut-off"line be car light irradiation to clear zone with not being irradiated to（Or seldom it is irradiated to）Dark space between boundary
Line.Smooth "cut-off"line can provide driver's more preferably driving comfort.But if cut-off linear dispersion is serious, can attract to take charge of
The excessive notice of machine, while the identification to illuminated object is reduced, driver may be caused can not normally to distinguish front when serious
Object and trigger accident.The color of headlamp is distinctly claimed in ECE regulations, is regulation white.In the market portioned product is adopted
Weaken dispersion phenomenon with the method for double light barriers, but sacrifice the efficiency of system simultaneously, the present invention can weaken dispersion phenomenon, together
When again will not sacrificial system efficiency.
The content of the invention
To solve the above problems, the present invention provides a kind of projection-type headlamp optical system, by dead line light barrier
A triangular prismatic type lens are added in outside, and triangular prismatic type lens sizes are millimeter rank, and triangular prismatic type lens moulding follows cut-off
Line light barrier, and therewith into certain inclination angle, not plus during triangular prismatic type lens, from the top through the white light of dead line baffle plate,
Can occur dispersion at dead line, based on blue light；Now, installed additional on the outside of dead line baffle plate with the triangular prismatic type at certain inclination angle
Lens, make by the optical dispersion of triangular prismatic type lens into based on feux rouges and appearing near dead line；Finally based on blue light
The cut-off Line beam and beam combination based on feux rouges, show the dead line of white, solve what is occurred in background technology
Problem.
It is an object of the invention to provide a kind of projection-type headlamp optical system, includes light source, has on the right side of the light source
Reverberation bowl, light source are located at the focal position of reverberation bowl first；Right-hand member bottom is provided with dead line baffle plate in the reverberation bowl, described section
It is the other triangular prismatic type lens of grade that only line baffle plate right hand top, which is provided with size, triangular prismatic type lens and dead line baffle plate it
Between oriented right-oblique angle and angle adjustable；The reverberation bowl right is provided with convex lens.
Further improvement is that：The light source is Xe lamp bulb either halogen bulb or LED light source.
Further improvement is that：The triangular prismatic type lens are glass material or plastic material.
Further improvement is that：The realization of dipped beam light type can be reflected by free form surface, can also use dead line baffle plate shape
Into "cut-off"line.
Further improvement is that：The convex lens are glass material or plastic material.
Further improvement is that：The reverberation bowl is ellipsoid reverberation bowl.
Beneficial effects of the present invention：The present invention by the outside of dead line light barrier add a triangular prismatic type lens, three
Angle prismatic lenses size is millimeter rank, and triangular prismatic type lens moulding follows dead line light barrier, and therewith into certain inclination angle,
Not plus during triangular prismatic type lens, from the top through the white light of dead line baffle plate, can occur dispersion at dead line, using blue light as
It is main；Now, install additional with the triangular prismatic type lens at certain inclination angle, make by the photochromic of triangular prismatic type lens on the outside of dead line baffle plate
Dissipate into based on feux rouges and appear near dead line；Finally the cut-off Line beam based on blue light and the light beam based on feux rouges
Superposition, show the dead line of white；Compared with conventional method, the present invention can weaken dispersion phenomenon, while will not sacrifice again
System effectiveness, improve light efficiency.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Wherein：1- light sources, 2- reverberation bowls, 3- dead line baffle plates, 4- triangular prismatic type lens, 5- convex lens.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, the embodiment
It is only used for explaining the present invention, is not intended to limit the scope of the present invention..
As shown in figure 1, the present embodiment provides a kind of projection-type headlamp optical system, include light source 1, the light source 1
There is reverberation bowl 2 on right side, and light source 1 is located at the focal position of reverberation bowl 2 first；Right-hand member bottom is provided with dead line in the reverberation bowl 2
Baffle plate 3, it is the other triangular prismatic type lens 4 of grade that the right hand top of dead line baffle plate 3, which is provided with size, triangular prismatic type lens
Oriented right-oblique angle and angle adjustable between 4 and dead line baffle plate 3；The right of reverberation bowl 2 is provided with convex lens 5.
The light source 1 is Xe lamp bulb either halogen bulb or LED light source.The triangular prismatic type lens 4 are glass material or modeling
Expect material.The realization of dipped beam light type can be reflected by free form surface, can also use dead line baffle plate 3 to form "cut-off"line.Institute
It is glass material or plastic material to state convex lens 5.The reverberation bowl 2 is ellipsoid reverberation bowl.
By adding a triangular prismatic type lens 4 in the outside of dead line light barrier 3, the size of triangular prismatic type lens 4 is millimeter
Rank, the moulding of triangular prismatic type lens 4 follows dead line light barrier 3, and is not adding triangular prismatic type lens into certain inclination angle therewith
When 4, from the top through the white light of dead line baffle plate 3, can occur dispersion at dead line, based on blue light；Now, in dead line
The outside of baffle plate 3 install additional with the triangular prismatic type lens 4 at certain inclination angle, make by the optical dispersion of triangular prismatic type lens 4 into using feux rouges as
Lead and appear near dead line；Finally the cut-off Line beam based on blue light and the beam combination based on feux rouges, show
The dead line of white.
