Abstract
The utility model relates to a middle light source device of an automobile headlamp. The device is arranged in the automobile headlamp and includes a lens body, a lens body support, a fixed shading piece, a low beam lamp reflect cup, a high beam lamp reflect cup, and an adjusting plate, the low beam lamp reflect cup and the high beam lamp reflect cup are arranged on the adjusting plate, the fixed shading piece is arranged between the lens body and the low beam lamp reflect cup, a middle light source assembly is arranged on the low beam lamp reflect cup and is composed of an LED lamp, an LED reflect cup and an LED heat radiation group, and a movable shading piece capable of shading the light path of the middle light source assembly is hinged on the fixed shading piece. By arranging such a structure, the LED lamp arranged behind the low beam lamp lens body has a main light height of 1.5m, the circuit of the LED lamp is on to enable the light beam of the LED lamp to realize the irradiation in the area from 30m to75m, therefore, the device provided has the advantages of simple structure, convenient operation and good stability, and can be widely applied on the self-adaptive head lamp lighting system of various automobiles.
Description
Technical field
The utility model relates to the technical field of vehicle head lamp system, particularly changes the device of headlamp irradiation distance.
Background technology
The society that modern times develop rapidly made the running of urban road high speed, and all backroads has stepped into the transition of urbanization.The illumination of traditional car headlamp has only dipped headlights and two lighting sources of high beam, and this is the development of incompatibility social city, throws light on when not enough at the urban road dipped headlights, can cause pedestrian and intersection car personnel dazzling when using the high beam illumination.When big rainy day or greasy weather, the dipped headlights illumination is not enough, and the far lighting light source is mostly by the globule and water smoke refraction, and reflection loss the illuminance of light, cause the visibility variation in the place ahead.In the vehicle head lamp system, effective irradiation distance of dipped headlights is generally about 25 meters, effective irradiation distance of high beam is generally about 120 meters, light scattering is higher, when vehicle when avenue weather travels, high beam need be closed, and the irradiation distance of dipped headlights is limited, so just has certain blind area.At misty rain weather, headlamp light fills the air unclear, thereby causes Forward Visbility relatively poor.These defectives all exist in present most of car headlamps.
The utility model content
The purpose of this utility model is the weak point that overcomes above-mentioned prior art, proposes a kind of simple in structure, middle light supply apparatus that can improve the vehicle head lamp of the security that car travels.Middle light supply apparatus can increase dipped beam to the stage casing illuminance between the distance light, and this device cooperates self-adaptive headlamp system simultaneously, can not produce dazzling influence to pedestrian and vehicular traffic in the turning road segment segment.
The purpose of this utility model is achieved by the following technical solution: a kind of middle light supply apparatus of vehicle head lamp, be installed in the vehicle head lamp, include lenticular body, the lenticular body support, fixing anti-dazzling screen, the dipped headlights reflector, the high beam reflector, adjustable plate, dipped headlights reflector and high beam reflector are installed on the adjustable plate, and fixedly anti-dazzling screen is between lenticular body and the dipped headlights reflector, it is characterized in that: middle light source assembly is installed on the dipped headlights reflector, middle light source assembly is by the LED lamp, the LED reflector, LED heat radiation group constitutes, on fixing anti-dazzling screen, also be hinged with one can block in the movable anti-dazzling screen of light source assembly light path.Further, dipped headlights reflector rear end has a hole, and middle light source assembly is installed on the dipped headlights reflector by this hole.Movable anti-dazzling screen is installed in fixedly on the anti-dazzling screen by rotating shaft.Also be provided with electromagnetic driver, the output of electromagnetic driver drives power transmission shaft.
Such design, head lamp structure can be satisfied 1.5 meters the middle light source that the illumination height is risen by ground in the 30-75 rice left and right sides irradiation distance of our needs and 60 meters, and be simple in structure, easy to operate, good stability.

The specific embodiment
Referring to Fig. 1-Fig. 5, the middle light supply apparatus of present embodiment is made up of following several parts: lenticular body 1, and lenticular body support 2, fixedly anti-dazzling screen 3, movable anti-dazzling screen 4, electromagnetic driver 5, dipped headlights reflector 6, adjustable plate 7, high beam reflector 8, power transmission shaft 9 and middle light source assembly.Wherein, middle light source assembly is by LED lamp 11, LED reflector 12, and LED heat radiation group 13 constitutes.
Lenticular body 1 is installed on the lenticular body support 2, movable anti-dazzling screen 4 can the mistake power transmission shaft be installed in fixedly on the anti-dazzling screen 3, electromagnetic driver 5 is by power transmission shaft 9 up-down adjustment activity anti-dazzling screens 4, there is a hole 10 dipped headlights reflector 6 rear ends, and middle light source assembly is installed on the dipped headlights reflector 6 by this hole 10.The LED lamp 11 of middle light source assembly is arranged in the LED reflector 12, and LED heat radiation group 13 then is arranged at LED reflector 12 outer rear portions (as shown in Figure 5).Lenticular body support 2, fixedly anti-dazzling screen 3, and dipped headlights reflector 6 and high beam reflector 8 are installed on the adjustable plate 7.By of the control of external circuit switch, and connect LED lamp 11 power supplys, realize control the movable anti-dazzling screen 4 of light source in producing to electromagnetic driver 5.
Fig. 2 is the state diagram under the situation that electromagnetic driver 5 does not have to switch on, and electromagnetic driver 5 produces active forces to power transmission shaft 9, thereby makes movable anti-dazzling screen 4 be in the closed condition of not opening, and middle light source also is in closed condition.
Fig. 3 is the state diagram of electromagnetic driver 5 energising under there is something special, after electromagnetic driver 5 energisings, promote power transmission shaft 9 and rotate, thereby drive activity anti-dazzling screen 4 is upwards opened, in LED lamp 11 circuit of light source assembly connect, the irradiation distance that makes dipped headlights becomes about 75 meters by original 25 meters.
Certainly, only enumerated some preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
