Description
Technical field
The present invention relates to a kind of multifunctional headlamp device, especially ellipse lamp device.In this lamp, produce focal point by the light source that is arranged in the reflector.Usually, light source is arranged on the first focus place with the reflector of ellipsoid form, and described focal point is formed on the second focus place of reflector.Then by convertible lens for example plane-convex lens focal point is projected on the road surface.
Purpose of the present invention is to provide a kind of scheme that is used for especially satisfying from simple relatively ellipse lamp device acquisition the light beam corresponding with various "cut-off"lines of various standards and/or rule under the situation that does not rely on many block pieces basically.
Background technology
The field of the invention is substantially the lighting device of automotive lamp.In this field, known have various lamp devices, wherein mainly contains:
Side lamp, its intensity and scope are less;
Dipped headlights, the bigger and scope on road of its intensity is approximately 70 meters, and they are mainly used in evening, and wherein light intensity can not allow the travel driver of vehicle dizzy;
The auxiliary lamp of remote headlamp and remote type, wherein the visual range on road is approximately 200 meters, and must turn off so that can not make its driver dazzling when surpassing other vehicle at these lamps;
Fog lamp.
In addition, known a kind of improved lamp, it is called as difunctional lamp, it has made up the function of dipped headlights and high beam: for this reason, for example the removable block piece that is made of for example metallic plate can be set in this difunctional lamp, it can be on request the scope of the light beam that produces from the light source that wherein can not stop by lamp and this light corresponding to the primary importance of the scope of main beam lamp and the scope that has wherein stopped segment beam that the light source by lamp produces and this light be confined to move between the second place of scope of dipped headlights.This lamp must produce in the second place has the adjusting "cut-off"line corresponding with dipped beam, and the form of this "cut-off"line is provided by the block piece form of stopping segment beam.This design mainly is used in the ellipse lamp device.
But, the conventional lights device of being mentioned just now, especially those produce the light beam that needs improvement as the lamp device of dipped headlights when these lamp devices are used in some condition.
Therefore, at vehicle during at running on expressway, the optical axis that wise is accumulates in the lamp device with the light beam of dipped headlights is sentenced and is just made the beam propagation that is produced get more farther.On the contrary, when vehicle travels in the city, needn't make the beam propagation must be with the same far away on unimpeded road.
Therefore, except traditional main lamp function especially dipped beam and distance light, various improvement have appearred.Noted developing perfect functions or Premium Features, these functions have changed the location of the "cut-off"line of the light beam that is produced a little, and function wherein especially has:
The function that is called as the urban type lamp in English is used for the city light beam.This function can reduce the scope of this lamp device by widening dipped headlights light a little;
The function that is called as highway type lamp in English is used for high-speed functions light.This function increases the scope of dipped headlights.
In addition, must be noted that for the country that keeps to the right that the "cut-off"line of dipped headlights light beam is aimed at respect to the vertical centre axis, therefore in the country that keeps to the left, observe kindred circumstances.Fig. 1 schematically demonstrates four projections on the plane of the various light beams of mentioning just now in the mode of example.This plane projection surface is arranged to face toward described lamp device with its optical axis vertical ground.The deepening part of these projections is corresponding to the shortage of light in this part, and white portion is corresponding to normally being shone by described lamp device.Therefore, demonstrated first "cut-off"line 101 corresponding with dipped beam in the traffic of keeping to the right, with corresponding second "cut-off"line 102 of highway light beam in the traffic of keeping to the right, with corresponding the 3rd light and shade dead line 103 of city light beam or fog lamp, with corresponding the 4th "cut-off"line 104 of dipped beam in left-hand traffic, with corresponding the 5th "cut-off"line 105 of highway light beam in left-hand traffic and six "cut-off"line 106 corresponding with main beam.
Therefore expect proposing to change the lamp device of the "cut-off"line of the light beam that they produce, so that can alternately propose especially at six kinds of light beams shown in Fig. 1.
For this reason, various solutions have been proposed in the prior art.
First kind of solution described in document US 5673990 relates to a kind of like this lamp device, and it is provided with and is particularly useful for the vertical movable screen board that slides so that form the light beam with specific "cut-off"line on request.
Described in second kind of solution described in the European patent application EP 1197387 and to have adopted shape to be roughly square plate in each lamp device in the dipped beam type, it self rotates, and rotation tilts with respect to the key lighting axis.Each side of this plate is enabling to obtain the light beam corresponding with specific "cut-off"line by rotating when this plate makes described side facing to the light source of described lamp device.
But, in these two kinds of solutions, carry out the change in location of screen board or movable platen so that lead to second light beam by inappropriate transition stage, and change the luminous intensity of having disturbed below "cut-off"line with second "cut-off"line from first light beam with first "cut-off"line.And first kind solution needs special complexity, high-precision mechanism.

Surpass about 30 ° or around axis 18 rotation: main beam less than about 30 °; It is to be noted that in according to this embodiment of the invention, so block piece 16 exists two different being used to obtain the position of main beam; Therefore the latter can directly obtain, and need not be by the intermediate steps corresponding with other light beam, no matter this block piece is arranged in the left-hand traffic structure or in the right-hand traffic structure.
Have been found that by continuous layout area 38,40,44 and 46 dexterously utilize block piece 16 to obtain up to 6 different light beams, this block piece size is also less, and its motion is carried out around single rotation 18 simply.In the enumerating of each possible position of block piece, be understandable that, some zone, even some subparticipation in the zone of component part 36 and 37 realizes several dead lines, therefore participates in producing several light beams.
In one embodiment, for example drive block piece 16 rotations at stepper motor type motor 50 seen in fig. 6 by actuator, this comprises for example 96 steps.This motor is arranged on lamp device inside, perhaps is arranged on below the lens carrier 10.It is kept by the fastening system that for example comprises nut 52.Its running is by microprocessor management, and wherein the ad-hoc location of block piece 16 is stored in advance, described especially just now six positions.Can from fascia, be controlled at one of them position of the block piece 16 in the memory storing in advance by the driver.
Fig. 9 a-9b demonstrates second embodiment according to block piece of the present invention in the mode of front view and side view.
Shown in Fig. 9 a, this block piece has active edge contour by two plane domains 60,60 ' constitute at last 2 places of highly holding, described plane domain be arranged on two plane domains 61,61 of being located at intermediate altitude n1 place ' between, these zones self are arranged on be located at below on each side of plane domain 62 at height n0 place.In addition, as among first embodiment, two continuous level zones interconnect by tilting zone: each zone 60,60 ' and 61,61 ' between zone 63,63 ' and zone 61,61 ' and zone 62 between zone 64,64 '.
By adopting wherein edge 62 to be arranged to the middle position of the position relative, thereby can obtain following various light beams with this block piece as this block piece with the middle position of groove 17:
Around axis 18 about 10 ° to right rotation: the highway light beam in right-hand traffic 102, the sub-fraction in zone 62 and these parts 61 and 60 major part are filled on length in the whole groove 17;
Around axis 18 about 21 ° to anticlockwise: right-hand traffic 101, these parts 62,61 ' and 60 ' on length, be filled in the whole groove 17;
Around axis 18 about 20 ° to anticlockwise: the highway light beam in the traffic 105 leftward, sub-fraction zone 62 and part 61 ' and 60 ' major part on length, be filled in the whole groove 17;
Around axis 18 about 21 °: be used for the light beam of left-hand traffic 104, and part 62,61 and 60 is filled on length in the whole groove 17 to right rotation;
Around axis 18 towards anticlockwise surpass about 72 ° or towards right rotation less than about 72 °: main beam.
This block piece is particularly favourable in " highway " position, thereby enabling to reduce makes the dazzling danger of driver of coming in the opposite direction.
Fig. 9 b enables to distinguish another particularity according to the block piece of second embodiment, these block piece 16 parts be not have an active edge 34 but two 34 and 34 ', these two with respect to optical axis 18 biasings and have identical profile.More particularly these have the zone 60,61,63,60 of repetition ', 61 ', 63 ', and zone 64,64 ' and 62 do not repeat.Specifically, the edge 34 in non-repeat region ' have the edge at enough low height place, thereby become optics unavailable guarantee simultaneously edge 34 ' mechanical continuity.As can be seen, active edge 34 is arranged on 34 ' back, repetition edge with respect to the direction of light from the light source that links to each other with reflector.The selection that block piece is repeated has reduced the problem that occurs iridescence at the "cut-off"line place.Just make selection that some part of block piece repeats based on such observation, especially the aberration phenomenon is more horrible for passing beam, because "cut-off"line is incident upon from the relatively short distance of automobile.But this situation is different with the light velocity of highway type, and wherein "cut-off"line throws fartherly, and the more difficult iridescence of perceiving.Therefore, have only the zone of close optical axis to repeat (luminous flux maximum there), and be arranged in the active region of the block piece that is used for passing beam.Can also select whole block piece is repeated.
Therefore the present invention enables to take block piece according to the quantity and the form of required "cut-off"line, keep effect, compact and convenience simultaneously, and do not have the vision trouble for the driver or for the driver of the automobile of on road, advancing in the opposite direction from a "cut-off"line to another.
