Description
Technical field
The present invention relates to a kind of automobile-used head light, relate in particular to the Intelligentized front lamp for vehicle that a kind of irradiating angle, irradiation area of not realizing turning to the dipped beam light source by mechanical rotation changes along with the variation of front wheel angle.
Background technology
Present automobile-used head light generally adopts halide torch, also useful xenon lamp, and these two kinds of lamps all carry out light by lamp reflector and converge.Under this prerequisite, the intelligentized design of relevant head light that has occurred all is to take whole head light to follow turning to of wheel and move mechanical type certainly to rotate.Disclose " a kind of head light of controollable self-propelled vehicle " as Chinese patent literature 200410078300.8, it comprises lamp socket, lamp housing, connection lead and installation accessories; Its head light also has lifting bar, articulated joint, driving and driving device and bearing; Lamp socket and lifting bar flexibly connect by articulated joint, and actuating device is connected with lifting bar with lamp socket by driving device, can drive lamp socket and make spatial rotational and the reciprocal up-and-down movement of lifting bar.Lifting bar is installed on the car body by bearing.The driving staff controls each actuating device as required makes head light do moving or rotating of certain amplitude relative to vehicle body.The head light that this mechanical type rotates, though realized the multi-angle irradiation, speed of response is slower, i.e. there is certain hysteresis in rotation with respect to front-wheel, so the effect of bringing is not ideal enough, and has certain potential safety hazard.
Summary of the invention
The change that the present invention mainly solves the irradiating angle of present Intelligentized front lamp and irradiation area is rotated by mechanical type and is realized, has certain hysteresis with respect to the rotation of front-wheel, and result of use is undesirable, and has the technical matters of certain potential safety hazard; Provide a kind of and do not realize the Intelligentized front lamp for vehicle that the irradiating angle of head light and irradiation area change with the rotation of front-wheel by mechanical rotation, its speed of response is fast, does not have hysteresis phenomenon, and the result of use ideal is guaranteed traffic safety.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: the present invention includes distance light light source, dipped beam light source, turn to the dipped beam light source, the turning flash light source, the described dipped beam light source that turns to comprises the A that is arranged in order from the inside to surface
1District～An district turns to the dipped beam light source, and the dipped beam light source that turns in each district is made up of several LED, and the LED in each district connects the led drive circuit of local area, and led drive circuit connects the mouth of decoding scheme again, the mouth of the input termination central authorities central controller of decoding scheme; An input termination front wheel steering angle degree sensor of central authorities' central controller, the mouth of another input termination or door, or two input ends of door connect distance light switch and dimmer control respectively.It at first is the control that is controlled by distance light light source, dipped beam light source that A1～An turns to the dipped beam light source as intelligence, that is to say the switch of only opening distance light light source or dipped beam light source, and the LED in A1～An zone just can be activated.When the distance light switch is opened (perhaps dimmer control is opened), central authorities' central controller by or door receive a useful signal, this moment is if front-wheel steering angle sensor is sent the deflection angle useful signal of a N1 degree, then the LED in A1 district is lighted, along with the increase of front-wheel steering angle, A2, A3 ... the LED in An district is lighted successively.Thereby realize not making the function of head light light-illuminating zone automatic variation along with the variation of front wheel angle by mechanical rotation.The luminous speed of LED is fast, does not have hysteresis phenomenon than the rotation of front-wheel, and the result of use ideal is guaranteed traffic safety.A1, A2 ... what of An zone decide according to the accuracy rate of front-wheel steering angle sensor, and promptly the front-wheel steering angle that arrives of front-wheel steering angle sensor is accurate more, and then the zone that A1～An marked off is just many more.Difference by LED is arranged installation, also can improve car light design-calculated degree of freedom.
As preferably, described A
1The axis of the LED in district～An district is from A
1It is outward-dipping gradually successively to distinguish the An district.Because LED has very strong directivity as light source, above-mentioned design guarantees that further front-wheel turns to the conformability of angle, zone and the front wheel angle of dipped beam light source irradiation when rotating, also guarantee exposure intensity simultaneously.
As preferably, described turning flash light source comprises the B that is arranged in order from top to bottom
1District～Bn district turning flash light source, the turning flash light source in each district is made up of several LED, and the LED in each district connects the led drive circuit of local area, and led drive circuit connects the mouth of described decoding scheme again.B1～Bn also is the control that is controlled by distance light light source, dipped beam light source as intelligent turning flash light source, that is to say the switch of only opening distance light light source or dipped beam light source, and the LED in B1～Bn zone just might be activated.When the distance light switch is opened (perhaps dimmer control is opened), central central controller by or door receive a useful signal, this moment is as long as front-wheel steering angle sensor is sent a useful signal, then B1, B2 ... the LED in Bn district is lighted successively in turn.Stir just as eyes, reach the effect as the magic.
As preferably, described distance light light source is made up of several distance light LED, and distance light LED connects the distance light led drive circuit, and the distance light led drive circuit is again with the distance light switch and receive or the input end of door.Make the head light unification make light source, guarantee that control is consistent, good looking appearance with LED.And LED has energy-conservation, advantage such as the life-span long, non-maintaining, explosion-proof, easy to control and environmental protection.
As preferably, described dipped beam light source is made up of several dipped beams LED, and dipped beam LED is near the light led drive circuit, and the dipped beam led drive circuit is again with dimmer control and receive or the input end of door.Make the head light unification make light source, guarantee that control is consistent, good looking appearance with LED.And LED has energy-conservation, advantage such as the life-span long, non-maintaining, explosion-proof, easy to control and environmental protection.
The invention has the beneficial effects as follows: be divided into the A that is arranged in order from the inside to surface by turning to the dipped beam light source
1District～An district, and adopt LED as turning to the dipped beam light source, again by the increase of circuit realization along with the front-wheel steering angle, A
