Description
Technical field
The present invention relates to the lighting system field of intelligent control technology of automobile more particularly to a kind of vapour based on SFV and DLP
Vehicle intelligence headlamp lighting device.
Background technology
With the fast development of society, automobile quantity is increasing, and the traffic safety brought therewith also more induces one to close
Note, especially in night traffic Frequent Accidents.According to statistics, the traffic accident of 70% or more the country was occurred at night, and night
Volume of traffic but less than the 1/3 of total volume of traffic, it is seen that night occur traffic accident probability be far longer than daytime.To find out its cause,
The improper use of distance light causes glare of driver when mainly having the poor light at night, underlit and meeting, and wherein distance light uses
It is improper to have accounted for 40% or so.Therefore, it solves the problems, such as to be dazzle the eyes caused by distance light in driving conditions to improving travel safety and relaxing
Adaptive has very important significance.
DLP (Digital Light Processing) display technology was published by American TI Company in 1994, core
Heart device is DMD (Digital Micro-Mirror Device) chip.DMD is a kind of spatial light modulation device, will be micro- anti-
It penetrates lens array and electricity, machine controller part is integrated on CMOS chip, control turning for each micro-reflector respectively by digital signal
Dynamic state, to control the reflection direction of light, the light to entering optical projection system carries out spatial modulation, realizes realtime graphic life
At function.The deflection angle of common DMD micro mirrors is mostly 10 ° or 12 °.
The operation principle of DMD elements, by taking micro mirror deflects ± 12 ° as an example, there are three each micro mirrors in micro reflector array
State：The flat ＂ states of the ＂ parallel with DMD element planes deflect that+12 ° of ＂ opens ＂ states and the ＂ of -12 ° of deflection closes ＂ states, and at work
Only there is ＂ and opens ＂ states and the passes ＂ ＂ state two states.When being used cooperatively with optical projection system, the normal parallel of DMD planes is in projection
The primary optical axis of system when the illumination light from light source is incident on after relay system on DMD, is incident on each DMD micro mirrors
Light is similar to a light cone, and primary optical axis and DMD plane normal angles are 24 °.When micro mirror, which is in ＂, opens ＂ states, illumination light master
Optical axis is 12 ° with micro mirror normal angle, and the primary optical axis after micro mirror reflects is parallel to the normal of DMD planes, can enter projection
The entrance pupil of camera lens, corresponding pixel is illuminated state on projection focal plane；When micro mirror, which is in ＂, closes ＂ states, illumination light and micro mirror method wire clamp
Angle is 36 °, and the primary optical axis and DMD plane normal angles after reflection are 48 °, cannot enter the entrance pupil of optical projection system, project focal plane
Upper corresponding pixel is dark-state.By the open and close state progress temporal modulation to each micro mirror, it can be achieved that the ash of each pixel
Degree variation, to carry out real time image generation.

Bright system and its car lighting signal device, including LiFi sending assemblies, LiFi receiving units and DLP projection system, with LED master
Transmission light source of the light source as LiFi sending assemblies, the running data of this vehicle is sent out, is then connect by built-in LiFi
The optical signal that component receives opponent vehicle is received, decoding obtains the running data of opponent vehicle, then adjusts DMD cores by automobile bus
Piece controls illumination region.The information exchange between vehicle is realized by LiFi technologies, and the accident that vehicle may occur is carried out
Early warning.The technical solution realizes the information exchange between vehicle using LiFi technologies, although the wireless communication rate of Lifi technologies
Quickly, 50Gbps or higher can be arrived, but Lifi technologies are a kind of middle the short distance wireless communication technologies, communication distance is very short, and
Decaying is serious；It since Lifi technologies are a kind of optical communication techniques, can be interfered by environment light source, if environment light source is operated in equally
Spectrum frequency range, and when brightness is higher, it is more likely that can not normal communication.Therefore, the technical solution of the application for a patent for invention is simultaneously
Remote vehicle identification or vehicle interaction are can not achieve, is affected by environmental disturbances, the accuracy for identifying or communicating
Relatively low, secondly, which also just cannot achieve track and keeps function, and finally, which needs
It wants one's own side and other side all to assemble LiFi sending assemblies and LiFi receiving units, otherwise can not carry out information exchange.
