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.
The disclosure provides a kind of laser car light, including laser light source 1 and fluorophor 3, and laser light source 1 is used to excite described glimmering
Body of light 3 shines, wherein, fluorophor 3 has the different fluorescence area of multiple colour temperatures, and fluorophor 3 can swash relative to described
Radiant 1 moves, so that the light that the laser light source 1 is sent is irradiated on different fluorescence areas.
Through the above technical solutions, so that the laser car light of the disclosure has colour temperature regulatory function, so as to preferably
Different road conditions and weather conditions are adapted to, obtain optimal illuminating effect.For example, under rainy day or haze weather, can be by car light
Colour temperature turn down, make light have bigger penetration range.
Here it is possible to make the colour temperature of each fluorescence area different in several ways.For example, can be in different phosphor regions
The fluorescent powder of different colours is applied on domain.For another example as shown in Figure 1, fluorophor 3 can be designed as to fluorescent wheel form, by respectively
A fluorescence area is designed as the annular section arranged around the pivot R of fluorescent wheel, and color is applied on each fluorescence area
Identical fluorescent powder (for example, yellow fluorescent powder), and make the glazed area accounting of each fluorescence area different.In such case
Under, glazed area accounting determines the colour temperature of fluorescence area, and glazed area accounting is bigger, and the colour temperature of fluorescence area is higher.Here,
Glazed area accounting refers on fluorescence area not by the ratio between gross area of the area of fluorescent powder covering and fluorescence area.
In Fig. 1 shows embodiment, formed with three fluorescence areas on fluorescent wheel：Fluorescence area A, fluorescence area B and
Fluorescence area C.For fluorescence area A, it is covered by fluorescent powder completely, glazed area zero, and glazed area accounting is minimum, colour temperature
It is minimum；For fluorescence area B, it includes fluorescent powder covering subregion B1 and printing opacity subregion B2, and glazed area accounting is printing opacity
The ratio of the area of subregion B2 and the gross area of fluorescence area B, its colour temperature is between fluorescence area A and fluorescence area C；It is right
In fluorescence area C, it includes fluorescent powder covering subregion C1 and printing opacity subregion C2, and glazed area accounting is printing opacity subregion C2
Area and fluorescence area C the gross area ratio, its colour temperature is highest in three fluorescence areas.When the color for needing adjusting car light
Wen Shi, can drive fluorescent wheel to be translated relative to laser light source 1 so that the light that laser light source 1 is sent be irradiated to it is different glimmering
On light region.In other embodiments, the quantity of fluorescence area can also be two, four, five etc..
The laser car light of the disclosure can have any suitable light path framework.As a kind of embodiment, such as Fig. 2 institutes
Show, in addition to laser light source 1 and fluorophor 3, laser car light can also include speculum 2, ellipsoid reflector 4 and projection lens 5,
Ellipsoid reflector 4 has the close to the first focus f1 of ellipsoid reflector center O and away from ellipsoid reflector center O
Two focus f2, fluorophor 3 are located on the first focus f1, and projection lens 5 and the reflecting surface of ellipsoid reflector 4 are oppositely arranged, the
Two focus f2 are between the first focus f1 and projection lens 5.Here, laser light source 1 for example can be laser diode.At this
In embodiment, laser light source 1 can be blue light laser diode.
The laser that laser light source 1 is sent is irradiated on fluorophor 3 after the reflection of speculum 2, and excitated fluorescent powder forms naked eyes
Visible white light.Since the direction of the white light is indefinite, if the light directly using untreated white light as car light,
Its penetration power is not strong, and range can not reach ideal distance, ineffective.Therefore, in the laser car light of the disclosure, pass through
Ellipsoid reflector 4 is set and fluorophor 3 is arranged on the first focus f1 of ellipsoid reflector 4 so that fluorophor 3 is sent
White light can be collected by ellipsoid reflector 4, through ellipsoid reflector 4 reflect light converge in ellipsoid reflection
Second focus f2 of cover 4, projection lens 5 is provided with behind the second focus f2, which is a convex lens, it is used
The light type for meeting lighting regulations requirement is changed into the white light for reflecting ellipsoid reflector 4, and is projected to outside car body,
Realize illumination.
In this embodiment, as shown in Fig. 2, being provided with unthreaded hole 41 on ellipsoid reflector 4, laser light source 1 is located at
The outside of ellipsoid reflector 4, the light that laser light source 1 is sent are irradiated to fluorophor 3 after the reflection of speculum 2 through unthreaded hole 41
On.In this way so that laser light source 1 has the arrangement space of bigger, so as to according to different brightness demand cloth
Multiple laser light sources 1 are put, improve the flexibility of car light, also, since laser light source 1 and speculum 2 are arranged in ellipsoid reflection
The outside of cover 4, therefore the light that will not be sent to fluorophor 3 causes to block, and improves light utilization.
In this embodiment, as shown in Fig. 2, the laser car light can also include being used for the catch 7 for adjusting light type,
The catch 7 is located at the front of the second focus f2 of ellipsoid reflecting cover 4 and neighbouring second focus f2 is set.
