Description
Technical field
The present invention relates to car light, in particular it relates to a kind of intelligent automotive light module and its application process.Described one kind
Intelligent automotive light module pacifies the size that the dark space to be formed only has head of the other side driver in diverse location, and other spaces are still protected
Hold completely without highlight illumination during target, such other side will not be dazzling.
Background technology
With vehicle travel at night, security issues become increasingly urgent, increasingly to automobile relevant manufacturer researching and developing new intelligence
Can car light technology.The light type that so-called novel intelligent car light technology is mainly developed for the purpose of realizing AFS and ADB functions simultaneously can

According to the present invention, the hot spot dimensional energy distribution of output is Lambertian.Simultaneously because laser irradiation power is than larger,
Using the scheme of the fluorescent wheel of dynamic rotary, it is to avoid laser long-time irradiation same point causes fluorescence ceramics to damage, such as Fig. 4 A-F,
Shown in Figure 10.
The size shape of the white hot spot at the fluorescent wheel back side, it is corresponding with its positive laser facula is radiated at but all remote little
In the size of DMD work surfaces.Relay lens group is imaged in through design after can be amplified the white hot spot at the fluorescent wheel back side
On the work surface of dmd chip, size meets the requirement of DMD work surfaces, avoids light to be irradiated to the region beyond work surface as far as possible,
Improve efficiency, such as Fig. 5 D, shown in Fig. 7.
Dmd chip is a kind of by Texas Instruments' exploitation, production, to the microcomputer for realizing being electronically entered, optics is exported
Electric system (MEMS), developer can perform high speed, efficient and reliable space light modulation by the system.Each DMD
Micro mirror (being implemented on corresponding cmos memory cell) containing most 2,000,000 independent controls.
Specifically, when a certain pixel in DMD work surfaces be in "On" state when, by relay lens group come light
Line, can be by the entrance pupil scope for being reflected into projection lens set of this specific pixel on DMD, so as to be projected lens group projection
Go out (on screen) formed a pixel lighted, as shown in Figure 6 C.If a certain pixel is in "Off" state, then will be
Irradiation light thereon is reflected into the light absorber being arranged in dmd chip system, because the light in the pixel is not thrown
Shadow lens group is received, so (on screen) can form accordingly dark pixel.In run duration, DMD controllers are each base
This memory element loads one " 1 " or one " 0 ".Next mirror image reset pulse can be applied, this can cause each micro mirror electrostatic
Deviate about hinge, so as to reach corresponding +/- 12 ° of states.The physics due to the resistance that can be subject to two spring thimbles
Stop, the deviation angle of the two effective statuses is repeatable.In projection systems ,+12 ° of state correspondence "ON" pixels ,-
12 ° of state correspondence "Off" pixels.It is programmed to create gray scale figure by the ON/OFF dutycycle to each eyeglass, and can
To multiplex multiple light sources to create RGB full color images.In other application, +/- 12 ° of states are two general purpose outputs mouths
One figure and its reverse figure are provided.
According to the present invention, using DMD DMDs, with laser source array light source, dynamic transmission-type fluorescence ceramics
Combination, creates a kind of new vehicle light illumination optics module design, there is provided a kind of high-resolution intelligent headlight of realizing
Optical solutions.And the program adopts LASER Light Source, the hot spot formed by laser, collimating array can be much smaller than LED light source,
Therefore the volume of whole system can significantly reduce, and it is essential that the optical efficiency of system can be higher than using the class of LED light source
Like device.
According to the present invention, both can guarantee that we (carried the car steering of the LED self adaptation headlights of technical solution of the present invention
Member) the illumination of front high-quality, will not form danger to other participants's (such as opposite, traveling in the same direction vehicle etc.) on road again
Dangerous is dazzling, it is ensured that the nighttime driving safety of each side on road.
