The fixed shell 2 of radiant and the fixed shell 3 of eyeglass collectively form a cavity, and laser light source is located in the cavity, free form surface
The inner surface of reflector 1 is coated with laser reflective film, the laser emitted with to improve free form surface reflector 1 to laser light source it is anti-
Rate is penetrated, guarantees the illumination intensity of laser car light；The main function of the fixed shell 2 of laser light source be install laser light source fixation and
Laser light source is protected, and connects other shells and constitutes total；The fixed shell 3 of eyeglass is that can connect shell, and eyeglass is fixed
The main function of shell 3 is to guarantee the position of Fresnel lenses and light source and connect laser light source shell and guarantee laser beam
Can be by Fresnel light-distribution lens 5, while guaranteeing that the light beam of laser light source can converge to 4 surface of yellow phosphorus filter, yellow phosphorus filter
The white light that mirror 4 is emitted is reflected away by reflector.Those skilled in the art can be anti-to free form surface according to different vehicles
The shape and structure of the fixed shell 2 of light shield 1, laser light source and the fixed shell 3 of eyeglass carry out autonomous Design.
As shown in Figure 1, laser light source includes being made of laser chip 6, wherein each laser chip 6 is fixed on laser light
On the approximately the same plane horizontal linear of the fixed shell 2 in source, the fixed shell 2 of laser light source and Fresnel light-distribution lens 5 and eyeglass are solid
Fixed shell connection, radiator 8 are fixed on the outer housing 4 of laser chip, and Fresnel light-distribution lens 5 are arranged in 6 front end of laser chip,
And convergence of the light beam of the blue of the laser emitting of laser chip 6 Jing Guo Fresnel lenses, exposes to the table of yellow phosphorus filter 4
Face, the blue laser that laser chip 6 emits pass through the white light beam of 4 back reflection of yellow phosphorus filter, expose to free form surface reflector 1
It is projected after reflection.The fluorescent powder of yellow, the two mixing is directly arranged in the front end of the laser emitting of laser chip 6 in other modes
Capable of emitting corresponding illumination white light；Laser chip 6 fixation back side of shell be equipped with radiator 8, the radiator 8 for pair
Laser chip 6 radiates, to guarantee that laser chip 6 works normally within the specified temperature range；Radiator 8 and laser core
The setting of piece 6 is in 1 rear end of free form surface reflector, for example, level of the setting position of laser chip 6 in free form surface reflector 1
Rear side, and the laser that laser chip 6 emits can be all reflected on free form surface reflector 1 by yellow phosphorus filter 4, laser
Chip 6 and Fresnel light-distribution lens 5, free form surface reflector 1 and yellow phosphorus filter 4 are relative positional relationships, laser chip 6
The change set will lead to the region of laser car light irradiation and angle changes, 5 He of laser chip 6 and Fresnel light-distribution lens
After relative positional relationship between yellow phosphorus filter 4 determines, the irradiating angle of laser car light and region are all anti-by free form surface
What the surface structure of light shield 1 determined, and the whole face type curvature of free form surface reflector 1 can according to the angle of incident light come
It calculates, free form surface reflector 1 is then that the angle by incident light and the GB 25991-2010 advised referring to Automobile require to determine
It is fixed, the laser irradiation that laser chip 6 emits to free form surface reflector 1, by 1 different zones of free form surface reflector,
It is projected after the different panel reflection of curvature from the fixed shell 3 of eyeglass, the photoirradiated surface and irradiating angle of injection are all by freedom
What the face type of curved surface reflector 1 determined, but the photoirradiated surface and irradiating angle of laser car light injection, which all meet vehicle rule, to be required.
As shown in Fig. 2, adjustable distance-light switch boards 7 in the part for blocking and not blocking the reflection of yellow phosphorus filter 4 by swashing
Movement between light, the switching between Lai Shixian laser car light lower beam illumination and far lighting.Adjustable distance-light switch boards 7 are set
It sets in the direction for going out light of yellow phosphorus filter 4, when adjustable distance-light switch boards 7 block the fraction of laser light of the transmitting of yellow phosphorus filter 4
When, the laser irradiation that the part that distance-light switch boards 7 are blocked is not adjusted is gone out, and then is reflected by free form surface reflector 1
Light, finally from lamp shade project, laser car light novel at this time be lower beam illumination；When adjustable distance-light switch boards 7 do not hide
When keeping off the laser that yellow phosphorus filter 4 emits, whole laser reflections to free form surface reflector 1 are reflected by free form surface reflector 1
After project, laser car light novel at this time be far lighting.
Novel laser car light in the present embodiment is by being arranged 5 He of Fresnel light-distribution lens in the front end of laser chip
The light beam of yellow phosphorus filter 4, laser chip transmitting passes through the convergence of Fresnel light-distribution lens 5, and exposing on yellow phosphorus filter 4 makes its photograph
The light beam of white is projected, white laser beam exposes to free form surface reflector, leads to after the reflection of free form surface reflector
The injection of Automobile lampshade is crossed, the positional relationship between other component can by the face type design to free form surface reflector after determining
To change the angle and range of emergent light, so that the laser car light be made to reach the required irradiating angle and range of vehicle rule.Meanwhile
The laser car light realizes being quickly converted between lower beam illumination and far lighting, this hair by adjustable distance-light switch boards 7
Bright structural integrity, and brightness of illumination ratio LED diode lights may be implemented and at least promote 30%, and consume energy than LED save to
Few 20%, and the service life is long.
As a kind of specific embodiment, novel laser car light further includes for controlling adjustable distance-light switch boards
The electromagnetic switch of 7 movements, adjustable distance-light switch boards 7 realized under the control of electromagnetic switch to the white laser reflected into
Row partial occlusion does not block, and has many advantages, such as that switching motion is rapid, safe and reliable.For example, being illustrated in figure 3 electromagnetic switch
The theory structure schematic diagram that adjustable distance-light switch boards 7 move is controlled, one end of spring 9 and adjustable distance-light switch in figure
Plate 7 connects, and the other end is connect with movable core (11), and iron core is wound with coil on (10), and after coil is powered, iron core (10) is produced
Raw electromagnetic attraction keeps movable core (11) mobile, so that adjustable distance-light switch boards 7 be driven to move, realizes adjustable distance
Light switch boards 7 are adjusted between laser in shield portions laser and not blocking, and then realize the lower beam illumination of laser car light and remote
Being quickly converted between optical illumination.
As a kind of specific embodiment, including radiator 8, laser chip 6 is connect with the fixed shell of laser, is radiated
Device 8 is connect with the fixed shell 2 of laser.It ensure that laser chip 6 can work normally.
As a kind of specific embodiment, the optical maser wavelength that laser chip 6 emits is 450nm, excitation yellow phosphorus filter 4
Yellow fluorescence bisque is emitted yellow light, so that the yellow light for making laser chip 6 launch blue laser and excitation is mixed into swashing for white
Light so that laser car light be capable of providing it is good illumination white light, it can be achieved that car light lighting demand.
As a kind of specific embodiment, the material of free form surface reflector 1 is plastic material, is conducive to mitigate novel
Laser car light entirety weight.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
