Description
The utility model belongs to lighting equipment for vehicle.
It is a kind of motor vehicle headlamp of dazzling the eyes of preventing, is adapted to the usefulness of various motor vehicles illuminations, illuminates the place ahead route or illuminates other zones of route or surrounding environment when being mainly used in driving.Dark and when not seeing the route steering vehicle, open this headlamp illuminated rows to sail as the driver of motor vehicles at light, can see route clearly, not overslaugh opposite vehicle driver travels and people's walkings (promptly preventing to dazzle the eyes) again.
At present, both at home and abroad the anti-glare motor vehicle headlamp is generally using, and particularly when the dark route motor vehicles meeting of night or light, needs beat this anti-glare car headlamp lighting, can anti-glare., the anti-glare motor vehicle headlamp that uses both at home and abroad is a dipped beam abblendbar headlamp at present, and the close together of illumination generally be no more than first three ten meters in car, and the brightest position is no more than ten meters.Therefore, though the anti-glare vehicle headlamp has been arranged at present, illumination distances is nearer, particularly during meeting, and the slow-down of still needing, safety inadequately again is so still can not satisfy the instructions for use of vehicle when meeting.The existing both at home and abroad anti-glare vehicle headlamp that is using by the headlight filament that instant and near light is formed, is located at the shadow shield of dip filament bottom, the anti-glare motor vehicle headlamp that parabolic mirror and parabolic lamp lens are formed.Before the dip filament of car light was arranged on the focus of parabolic reflector, the headlight high beam filament of car light was arranged on the focus of parabolic reflector.When opening the dip filament switch, dip filament is luminous, because the dip filament bottom is provided with a shadow shield, this shadow shield blocks its dip filament bottom, and make the Lower Half dull thread of car light, like this, the Lower Half of parabolic reflector does not have reverberation, therefore, first position areflexia light of car light.Like this, beyond car light shines one meter and the top of parabolic reflector central symmetry axis does not have the illumination light line, and the light on shadow shield top shines on the first half of parabolic reflector, through the parabolic reflector light reflected, see through parabolic lamp lens and shine (according to the reflection of light principle) downwards, light and road surface are intersected and are illuminated the road surface, so anti-glare.
The utility model provides a kind of middle dipped beam anti-glare motor vehicle headlamp, anti-glare light-illuminating distance is far away than the dipped beam anti-glare motor vehicle headlamp irradiation distance of present use, general irradiation distance is in the first six ten meters in car, the brightest position is within the first two ten meters to 50 meters scopes of car, therefore, use it can improve road speed and traffic safety when meeting, dipped beam anti-glare motor vehicle headlamp is formed the same substantially with the parts of the dipped beam anti-glare motor vehicle headlamp that generally uses at present in this, but, the position that the middle dip filament of middle dipped beam anti-glare motor vehicle headlamp is placed is different with the structure of lamp lens, as shown in Figure 1.
Dipped beam anti-glare motor vehicle headlamp in of the present utility model, its filament is made up of middle dip filament and two filaments of middle headlight high beam filament, middle headlight high beam filament places after the focus of parabolic reflector, usefulness as far lighting, middle dip filament places on the focus of parabolic reflector, and the low beam silk of existing anti-glare motor vehicle headlamp is placed on before the focus of parabolic reflector, and this is a fruitful improvement.Because middle dip filament places on the focus of parabolic reflector, the light of its filament light-emitting is through the reflection of parabolic reflector, parallel with the central symmetry axis of parabolic reflector, again through after the refraction of convex lens optically focused vehicle lamp glass, the distance of anti-dazzle lighting light is far away, and the brightest position is also far away.When the irradiation distance adjustment (screw position of this car light is fixed in adjustment) of dipped beam anti-glare motor vehicle headlamp in the handle was crossing to the first six ten meters of car and road surface, the anti-glare irradiation light was brighter 20 meters to 50 meters scopes.The improvement that another is bigger, it is exactly the improvement of the convex lens spotlight glass of dipped beam anti-glare motor vehicle headlamp in this, this lamp lens is a kind of convex lens spotlight glass, one side in the car light outside is the convex surface of lamp lens, one side in the car light inboard is the plane of lamp lens, in order to alleviate lamp lens weight and to save glass, makes the round cascaded surface (general 2~3) that concaves at the place, plane of lamp lens, but guarantee lamp lens intensity, its focal length does not change.For making laterally evenly degree of divergence increase of light, therefore, make some longitudinal grins (this lamp lens can form with mold) in the inboard one side of lamp lens, as Fig. 2, Fig. 3, shown in Figure 4.The focal length of this convex lens spotlight glass is 0.5~4 meter, and this focal range depends on that different motor vehicles are to the antiglare headlamp needs.
The utility model is concrete to be implemented and the course of work, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.Fig. 3 is the positive diagrammatic sketch of convex lens spotlight glass; Fig. 2 is lamp lens A-A cross sectional plan view and Fig. 4 B-B section left side view; Fig. 1 is the car light generalized section.Two filaments that the filament of car light is fitted together by middle dip filament (2) and middle headlight high beam filament (1), select that filament for use with switch (not marking on the figure) control, middle dip filament (2) places the place, focal position of parabolic reflector (4), and establish a shadow shield (3) in middle dip filament (2) bottom, the light of directive car light Lower Half when blocking its filament light-emitting, after middle headlight high beam filament (1) places the focus of parabolic reflector (4), this two filament (1) and (2) and shadow shield (3), can directly be contained in the car light of sealing, but two filaments will be drawn on the switch of three leads (wherein is the common point of two filaments) to the driver's cabin, perhaps with these two filaments and shield closes in a glass bulb, refill in a removable car light, then, again the front opening position of convex lens spotlight glass (5) and parabolic reflector (4) is linked up and this antiglare headlamp of constituting.This convex lens spotlight glass, one side in the car light outside is a convex surface, and the one side in the car light inboard is the plane, and two recessed circles of ladder (6) are inwardly made at this place, plane, and have some longitudinal stripes (7) on it, when headlight high beam filament in the needs (1) luminous lighting, distance light switch in opening makes it luminous, reflect through parabolic reflector (4), the degree of dispersing is less, after planoconvex lens spotlight glass (5) refraction is assembled again, and the position that need throw light in mobilite the place ahead; When dip filament (2) in the needs abblendbar throws light on, transform to the switch connection of middle dip filament (2), make it luminous.Because middle dip filament (2) bottom is provided with a shadow shield, having blocked this light shines to the car light Lower Half, place on the focus of parabolic reflector (4) owing to middle dip filament (2) again, so through reflective mirror (4) light reflected, being bordering on parallel rays penetrates, light after planoconvex lens spotlight glass (5) refraction is assembled again is on the road surface, directive car the place ahead.Because the central symmetry axis adjusted of parabolic reflector (4) is at the first six ten meters of car, and it is crossing with the road surface, light also can shine 60 meters with far, if adopting the focal length of convex lens spotlight glass (5) is one meter, so so the top dull thread of the central symmetry axis of the parabolic reflector (4) beyond the last rice of car light is but anti-glare.
