The present invention by arrange multiple LED assemble conjunction radar be operated, radar detects the presence of the car of approaching at a distance
, when have approaching vehicle near time, the range sensor in LED group closely detects the close situation of approaching vehicle, when sailing
When nearly vehicle enters the detection range of range sensor, corresponding LED group is extinguished, and other LED groups normally work, and i.e. avoid
The high beam impact on approaching vehicle in driving, also ensure that the illuminating effect of high beam, improves vehicle safety, and
Easy to operate, it is suitable for popularization and application in various road vehicle.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention；
Fig. 2 is single led lamp group structural representation.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of self-adjustable automobile-used LED high beam, it includes controlling processor 6, radar 4, circuit
Plate and setting multiple LED groups on circuit boards, each described LED group includes LED lamp bead 1 and leads to LED lamp bead 1
The LED driver 2 that oversampling circuit connects, each described LED lamp bead 1 is also equipped with a range sensor 3, described Distance-sensing
Device 3 is connected by circuit has sensor driver 5, the control signal outfan of described control processor 6 to be driven with LED by circuit
The dynamic control signal receiving terminal of device 2 and the control signal receiving terminal of sensor driver 5 are connected, described control processor 6
Detection signal receiving end is by circuit and the detection signal output part of range sensor 3 and the detection signal output part of radar 4
It is connected.
During use, driver starts LED high beam, and the LED lamp bead 1 in each LED group is bright, and in driving process, radar 4 is remote
Distance detection front with or without the vehicle of approaching, when have approaching vehicle near time, radar 4 sends detection signal to controlling processor 6,
Control processor 6 starts range sensor 3 by control sensor driver 5 and closely detects the close situation of approaching vehicle,
When approaching vehicle enters the detection range of range sensor 3, range sensor 3 sends detection signal to controlling processor 6, control
Processor 6 processed extinguishes corresponding LED lamp bead 1 by controlling LED driver 2, and after vehicle crosses, this LED lamp bead 1 lights again,
Now approaching vehicle is not in the detection range of range sensor 3 in LED group, and in neighbouring LED group, LED lamp bead 1 is not
Extinguish.In this way, the LED group in approaching vehicle respective regions is extinguished, and other LED groups normally work, and i.e. avoid and drive
Sail the impact on approaching vehicle of the middle high beam, also ensure that the illuminating effect of high beam, improve vehicle safety.
On the basis of technique scheme, in each LED group the direction of illumination of LED lamp bead 1 and range sensor 3 away from
From detection direction, there is certain angle.Being arranged such, in vehicle drive, two ends, left and right, headstock front portion are symmetrically installed LED distance light
Lamp, LED lamp bead 1 direction of illumination is the direction of advance of vehicle, and the distance detection direction of range sensor 3 is vehicle on neighbouring track
Close direction so that the traveling that distance detection more can react vehicle is live, and then ensures the accuracy controlling LED lamp bead.
On the basis of technique scheme, in each LED group the direction of illumination of LED lamp bead 1 and range sensor 3 away from
Angle from detection direction is 30 ° to 45 °.It is arranged such, during particular for the vehicle meeting travelled in opposite directions so that distance detection
The traveling that more can react vehicle is live, and then ensures the accuracy controlling LED lamp bead, meets actually used needs.
On the basis of technique scheme, in each LED group the direction of illumination of LED lamp bead 1 and range sensor 3 away from
Angle from detection direction is 25 ° to 30 °.It is arranged such, during particular for the vehicle cut-ins travelled in the same direction so that distance detection
The traveling that more can react vehicle is live, and then ensures the accuracy controlling LED lamp bead, meets actually used needs.
On the basis of technique scheme, the stepped distribution of multiple LED groups on circuit board is arranged.It is arranged such,
Multiple LED group is made mutually to have certain spacing distance, it is to avoid several LED group Vehicle during Crossing Event are turned off the light simultaneously, impact
The illuminating effect of high beam.
Limiting the scope of the invention, one of ordinary skill in the art should be understood that in technical scheme
On the basis of, those skilled in the art need not to pay various amendments or deformation that creative work can make still the present invention's
Within protection domain.
