Embodiment
The embodiment of the disclosure is described in detail below in conjunction with attached drawing.It should be appreciated that this place is retouched
The embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
According to a kind of embodiment of the disclosure, there is provided a kind of laser car light, including laser light source 1, fluorophor 3, ellipsoid
Face reflector 4 and projection lens 5, laser light source 1 shine for excited fluophor 3, and ellipsoid reflector 4 has close to ellipsoid
The first focus f1 of reflector center O and the second focus f2 away from ellipsoid reflector center O, fluorophor 3 are burnt positioned at first
On point f1, projection lens 5 and the reflecting surface of ellipsoid reflector 4 are oppositely arranged, and the second focus f2 is located at the first focus f1 and throwing
Penetrate between lens 5.Here, laser light source 1 for example can be laser diode.In the present embodiment, laser light source 1 can be
Blue light laser diode.
Fluorescent powder and diffusion particle are included in fluorophor 3, when the laser that laser light source 1 is sent is irradiated on fluorophor 3,
Excitated fluorescent powder forms macroscopic white light, and diffusion particle is used for the white light to external diffusion.Due to the white light
Direction is indefinite, if the light directly using untreated white light as car light, its penetration power is not strong, and range can not reach
It is ineffective to ideal distance.Therefore, in the laser car light of the disclosure, by setting ellipsoid reflector 4 and by fluorophor
3 are arranged on the first focus f1 of ellipsoid reflector 4 so that the white light that fluorophor 3 is sent can be by ellipsoid reflector 4
Collect, the light reflected through ellipsoid reflector 4 converges in the second focus f2 of ellipsoid reflector 4, in the second focus
Projection lens 5 is provided with behind f2, which is a convex lens, it is used for the white for reflecting ellipsoid reflector 4
Light changes into the light type for meeting lighting regulations requirement, and projects to outside car body, realizes illumination.
In the present embodiment, fluorescent powder is yellow fluorescent powder.It is understood that it can also be included in fluorophor 3
His one or more fluorescent powders, for example, at the same time comprising red fluorescence powder and green emitting phosphor to strengthen drilling for the white light of formation
Color.
In the present embodiment, the optical axis coincidence of the central axis of ellipsoid reflector 4 and projection lens 5.It is appreciated that
, the central axis of ellipsoid reflector 4 can also have a certain degree with the optical axis of projection lens 5, as long as ensureing ellipsoid
The light that face reflector 4 reflects can be to being irradiated on projection lens 5.Here, the central axis of ellipsoid reflector 4
It is exactly the line of the first focus f1 and the second focus f2.
In the present embodiment, unthreaded hole 41 is provided with ellipsoid reflector 4, laser light source 1 is located at ellipsoid reflector 4
Outside, the light that laser light source 1 is sent is irradiated on fluorophor 3 through unthreaded hole 41.In this way so that laser light source
1 has the arrangement space of bigger, so as to arrange multiple laser light sources 1 according to different brightness demands, improves the spirit of car light
Activity, also, since laser light source 1 is arranged in the outside of ellipsoid reflector 4, the light that fluorophor 3 will not be sent
Cause to block, improve light utilization.
Alternatively, in the present embodiment, laser car light further includes the speculum 2 positioned at the outside of ellipsoid reflector 4, swashs
The light that radiant 1 is sent is irradiated on fluorophor 3 after the reflection of speculum 2 through unthreaded hole 41.It is understood that at other
In embodiment, speculum 2 can not also be set, the light sent of laser light source 1 is shone directly on fluorophor 3.
In the present embodiment, laser light source 1 can be multiple that the plurality of laser light source 1 is around ellipsoid reflector 4
Central axis arranged for interval, the light that each laser light source 1 is sent are irradiated on fluorophor 3 through respective unthreaded hole 41.
Laser is directly projected outside car body after being burnt in order to avoid fluorophor 3, so as to cause car light not meet automotive lighting
Laws and regulations requirement and human eye may be damaged, in the present embodiment, unthreaded hole 41 is arranged in pairs in ellipsoid reflector 4
On, and first focus f1 center symmetric setting of two unthreaded holes 41 in each pair unthreaded hole 41 on ellipsoid reflector 4, also
It is to say, the line of two in each pair unthreaded hole 41 unthreaded hole 41 is by the first focus f1 of ellipsoid reflector 4 and anti-with ellipsoid
Penetrate the central axis upright of cover 4.In this way, once fluorophor is burnt, the laser entered from any unthreaded hole will not be
There is any light path behavior in ellipsoid reflector 4, but be directly emitted to ellipsoid from 180 ° of symmetrical another unthreaded holes of the unthreaded hole
Outside face reflector 4, in this way, need to only set extinction or diffusing structure (not shown) outside ellipsoid reflector 4, you can realize fluorescence
Body burns defencive function.
In such a case, it is possible to be unthreaded hole 41 quantity is equal with the quantity of laser light source 1 or unthreaded hole 41
Quantity is more than the quantity of laser light source 1.In the embodiment shown in Fig. 1, unthreaded hole 41 is four, and laser light source 1 is three, position
In the no corresponding laser light source 1 of the unthreaded hole 41 of bottom.
In the present embodiment, laser car light can also include being used for the catch 7 for adjusting light type, which is located at ellipsoid
The front of second focus f2 of face reflector 4 and neighbouring second focus f2 settings.
In order to improve the launching efficiency to fluorescent powder, extend the service life of fluorescent powder, in the present embodiment, laser car
Lamp can also include being used for the radiator 6 for radiating to fluorophor 3.
Preferably, opening is provided with ellipsoid reflector 4, which is located at ellipsoid reflector center O, radiator
6 one end is connected with fluorophor 3, and the other end is pierced by from opening.In this way, radiator 6 can farthest be reduced
Influence to the light absorption efficiency of ellipsoid reflector 4.
In conclusion the disclosure provide laser car light it is simple in structure, and due to used optical element (for example,
Ellipsoid reflector and projection lens) it is the very ripe element of processing technology, therefore production cost can be greatly reduced, have
Beneficial to popularizing for laser car light.Further, since there is the laser car light that the disclosure provides fluorophor to burn protection mechanism, because
This is also avoided that laser is directly projected outside car body in the case that fluorophor is burnt, and improves the safety of laser car light
Property.
The preferred embodiment of the disclosure is described in detail above in association with attached drawing, still, the disclosure is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the disclosure, a variety of letters can be carried out to the technical solution of the disclosure
Monotropic type, these simple variants belong to the protection domain of the disclosure.
It is further to note that each particular technique feature described in above-mentioned embodiment, in not lance
In the case of shield, it can be combined by any suitable means.In order to avoid unnecessary repetition, the disclosure to it is various can
The combination of energy no longer separately illustrates.
In addition, it can also be combined between a variety of embodiments of the disclosure, as long as it is without prejudice to originally
Disclosed thought, it should equally be considered as disclosure disclosure of that.
