Specific embodiment
The present invention is specifically described with reference to the accompanying drawing.
A kind of new type lens for automobile lamp, including light source 1, matrix, the light source 1 goes out light through matrix, described
Matrix includes the vertical correction plane of incidence 2, the arc correction plane of incidence 3, the sidelight correction plane of incidence 4, corrects plane of refraction 5, exit facet 6,
The light source 1 is point light source, and the light source 1 completes vertical direction light after 2 incidence of the vertical correction plane of incidence, through exit facet 6
Line is corrected and is projected, and after the front side light source of the light source 1 corrects the correction of the plane of incidence 3 by arc, is projected by exit facet 6, institute
After the light at left and right sides of light source 1 is stated by the sidelight correction correction of the plane of incidence 4, projected by exit facet 6,
The matrix includes rear basal plane 7, side group face 8, lid basal plane 9, and the side group face 8 is two crescent moons in left and right parallelly distribute on
The rear side of shape laminated structure, two side group faces 8 is connected by rear basal plane 7, and the front end in two side group faces 8 passes through outgoing
Face 6 connects, and top, the bottom end in two side group faces 8 pass through the connection of lid basal plane 9.
The arc-shaped structure of vertical cross-section of the vertical correction plane of incidence 2, exit facet 6, the arc correction plane of incidence 3, it is described to hang down
The straight correction plane of incidence 2, exit facet 6, the arc correction plane of incidence 3 are arc core with the light source 1.
The arc-shaped structure in horizontal cross-section of the arc correction plane of incidence 3, the left and right ends of the arc correction plane of incidence 3
It is connect with the front end of the sidelight correction plane of incidence 4, integral level section is in " m " shape structure, the water of the sidelight correction plane of incidence 4
Plane section is one of arc or linear type.
The fan-shaped structure of vertical cross-section of the correction plane of refraction 5, the rear side and the sidelight of the correction plane of refraction 5 are rectified
The rear side in normal incidence face 4 connects, and the front end of the correction plane of refraction 5 is connect with the side group face 8, the vertical correction plane of incidence
2 are located at the junction of the correction plane of refraction 5 and the side group face 8, and the correction plane of refraction 5 is in the horizontal direction to light source 1
It is close.
The quantity of basal plane 7 is two after described, and for two rear basal planes 7 in distribution up and down, the arc corrects the plane of incidence 3
Between two rear basal planes 7 and the arc correction plane of incidence 3 is embedded in from back to front between two side group faces 8,
The correction plane of refraction 5 is located at the rear portion in the side group face 8, the vertical correction plane of incidence 2 positioned at two side group faces 8 it
Between.
The light of 1 vertical direction of embodiment adjusts
Since light source 1 belongs to point light source, if directly incident from the rear basal plane 8, unirefringence can be first generated, and generates refraction
Have, can not be adjusted by the exit facet 6, so needing the light vertical incidence of the light source 1, i.e., be put light source 1 again
Setting the light in the inner arc arc core position of the vertical correction plane of incidence 2, along front side incidence then can vertically take in the matrix
In,
In vertical direction, the light after incidence can be radiated on lid basal plane 9 and exit facet 6, and wherein light will not be by described
Lid basal plane 9 projects lamps and lanterns, and projects from exit facet 6, when light is projected by the exit facet 6, due to hanging down for the exit facet 6
The straightforward arc-shaped structure in face, the refraction generated when into air dielectric, forms collimated light beam.
The adjustment of 2 horizontal direction glazed thread of embodiment
Fig. 2 is the structural schematic diagram that the new type lens of the present invention for automobile lamp are adjusted perpendicular light source, such as Fig. 2
Shown, identical as the principle in embodiment 1, light cannot be incident by rear basal plane 7, but needs to correct by the arc incident
Face 3, the sidelight correction plane of incidence 4 are incident, and unlike the first embodiment, during the adjustment of horizontal light, incident ray is not
It is vertical incidence, but reflects to specific angle,
When light is incident by the arc correction plane of incidence 3, by the media variations by air to matrix, realizes light refraction, make
Its become collimated light beam pass through the matrix, the linear structure in horizontal cross-section of the exit facet 6, thus by arc correct into
It is vertically to project that 3 light beam of face, which is penetrated, when projecting the exit facet 6, does not reflect, is still collimated light beam,
During light is by the sidelight correction intake to matrix of the plane of incidence 4, the refraction of two sides to the left and right can be generated, and most
It is irradiated on correction plane of refraction 5 eventually, light can reflect, inclination angle of the angle of emergence of each light with the correction plane of refraction 5
Complementation finally guarantees that each light forms the collimated light beam projected forward.
Embodiment 3
Fig. 3 is the structural schematic diagram that the new type lens of the present invention for automobile lamp are adjusted horizontal light, such as Fig. 3
It is shown, the light source 1 be point light source, before incidence be diverging light source, after incidence, due to the vertical correction plane of incidence 2,
Arc corrects the plane of incidence 3, the sidelight correction plane of incidence 4 and the adjustment for correcting plane of refraction 5, is formed when across matrix and is vertically sent out
It dissipates, in the horizontal direction parallel light beam, and is finally adjusted by the exit facet 6, form the whole directional light projected from the front to the back
Beam.
In above process, the outside of the rear basal plane 7, side group face 8, lid basal plane 9 and the correction plane of refraction 5 is in light
Line does not play dimming effect during correcting, it is possible to carved pattern above it.
In the case where there are multiple point light source light-emittings, pH effect can be carried out to each light source, be applied in combination.
Matrix can be rotated 90 ° with front-rear direction, the adjustment of horizontal direction and the adjustment of vertical direction are exchanged, allowed so
The adjustment and use of light are not influenced.
Embodiment 4
Fig. 4 is the irradiation illumination figure of the new type lens of the present invention for automobile lamp, as shown in figure 4, permitting model in size
In enclosing, it in above-below direction narrows the light of outgoing as far as possible, is very perfect for the angle for meeting laws and regulations requirement
Light shape.Meet the optic test value requirement of rules and regulations.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it
It is interior.
