As shown in figure 3, described control unit 50 includes controlling switch 51, information detecting unit 52 and the center being sequentially connected Processing unit 53, the CPU 53 is connected with first adjustment unit 40.Specifically, controlling switch 51 is used Family inputs control command, is started working before such as turning, turning is stopped after terminating.Described information detection unit 52 includes difference Illumination detection sensor, bend image acquisition device, the illuminating bundle angle detection sensing being connected with the CPU 53 Device, wherein illumination detection sensor are used for the intensity for detecting current outside illumination, and detection information is sent into single to center processing Member 53 is judged, if current outside illumination is sufficient, such as in non-travelling in fog day in the daytime, then need not adjust the irradiation of illuminating bundle Direction, now controls the first adjustment unit 40 without adjustment work, if current outside illumination is inadequate, as in the night or greatly Greasy weather gas is driven a vehicle, then needs to adjust the direction of illumination of illuminating bundle, the image for now gathering bend by bend image acquisition device is sent out CPU 53 is delivered to, image procossing is carried out by CPU 53, flexibility and the angle of inclination of bend is obtained, And laser beam is converted into the moving parameter of the upper surface of wavelength conversion unit 20 and the position tune of corresponding laser source unit 10 Whole parameter, the wherein adjusting parameter are specially the position adjustment of lasing light emitter 110 or light path turnover unit 120 or focusing unit 130 Parameter, it is consistent with the part for being currently needed for regulation.Above-mentioned parameter is sent to the first adjustment unit 40, the first adjustment unit 40 The position of laser source unit 10 is adjusted according to above-mentioned adjusting parameter information, that is, adjusts lasing light emitter 110 therein or light path turnover unit 120 or the position of focusing unit 130, so as to change laser beam projects to the position of the upper surface of wavelength conversion unit 20, make illumination Light beam deflects corresponding angle, at the same time, the position of illuminating bundle angle detecting sensor and illuminating bundle along assigned direction Correspondence, is detected, and the data detected are sent to CPU 53 in real time to the irradiating angle of illuminating bundle Row feedback regulation, improves degree of regulation and stability.
In summary, the adaptive laser lighting lamp that the present invention is provided, compared with prior art, has the advantage that:
(1) control the first adjustment unit 40 to adjust the position of the laser source unit 10 by control unit 50, make laser Upper surface of the laser beam that source unit 10 is projected on wavelength conversion unit 20 along wavelength conversion unit 20 is moved, so as to change lamp The direction of illumination of light, realizes that front lamp of vehicle effectively adjusts the purpose of light angle according to the specific situation in turning road surface, makes driver Pavement behavior can be preferably observed, the security of vehicle traveling is improved;
(2) some compact arranged fluorescence coatings 210 are set in wavelength conversion unit 20, and now laser beam is along wavelength convert The upper surface movement of unit 20 is that laser beam is moved between some fluorescence coatings 210, is set in the side periphery of each fluorescence coating 210 Diffusing reflection layer 60 is put, laser beam can be prevented to go out and formed the veiling glare in non-designated direction from fluorescence coating side diffusion, improved Illuminating effect, and when laser beam irradiates multiple fluorescence coatings 210 simultaneously, the size of hot spot can be expanded, change the shape of hot spot, So as to realize illumination zone, illumination distances and illumination direction that adjustment illuminating lamp in real time is needed according to road, driving peace is improved Full property and comfort level;
(3) present invention need not adjust whole car light, reduce energy expenditure, and control accuracy is high, and stability is good, applicable multiple In miscellaneous road and environment, applicability is wide, the need for meeting practical application conscientiously.
Although embodiments of the present invention are illustrated in specification, these embodiments are intended only as prompting, It should not limit protection scope of the present invention.It is equal that various omission, substitution, and alteration are carried out without departing from the spirit and scope of the present invention Should be comprising within the scope of the present invention.
