Abstract

The utility model discloses a front light and automobile meeting combined lamp of the automobiles. The automobiles run at night, lamp light is glaring when two automobiles meet. The combined lamp is composed of a general long shot lamp part composed of a light source and a reflecting cover and an automobile meeting lamp part composed of a tile-shaped reflecting board with asymmetric light sources, an arced prism and an optical grating. The light ray of the automobile meeting lamp is in the shape of the fan, the automobile meeting lamp has a clear upper interface, the light ray below the interface is bright, and the upper part of the interface has no the light ray. When the two automobiles meet, the meeting lamp automatically turns on and clearly irradiates road surfaces and the scenery of the front part without any glaring light ray so as to thoroughly solve the safety problem of the automobile meeting, and the front light and automobile meeting combined lamp has energy saving and low oil consumption without damaging tyres and the road surfaces when automobiles meeting.

Description

Front light and automobile meeting combined lamp of automobile

The utility model relates to automobile lamp.

Automobile is when night running and two cars are met, and light is dazzle the eyes, and must close to change lamp and slow down, with plan safety.Dazzle the eyes in order to solve nighttime meeting light, each state has all made improvement in various degree to the problems referred to above in recent years.For example: Japan " Mitsubishi " adds an anti-dazzle device in the recent photograph filament front of car light, and the light to the front upper place direct projection is blocked in attempt, and allows the light of directive front lower place pass through.And for example: Soviet Union's " volga " adds Yi Yuangai on car light bubble top, allows filament all block without reflection shield direct projection part (accounting for 1/3rd) forwards.For another example: domestic " Shanghai " adds anti-dazzle device outside on the car light silk, blocks upwards and the light of front upper place, and attempt reaches the abblendbar purpose.

But,, be not theoretic point source of light because filament has certain-length and shape, can not meet theoretical focal position fully, make the error of fit in addition, and the restriction of the design shape of reflection shield, cause many light scatterings, thereby failed to realize preferably the abblendbar purpose.Above each example of lifting though the certain effect of abblendbar is arranged, does not have in the countryside on the highway of street lamp, and scattered beam is still dazzle the eyes dazzling, influences safety traffic.

Task of the present utility model is the problem that solves vehicle at night meeting dazzling light, to reach the safe meeting of the normal speed of a motor vehicle, and the purpose of seldom take energy and physical, few oil consumption material, seldom hindering vehicle tyre and road surface, avoiding traffic accident and take place.

This combined light principle design is as follows:

Combined light is partly combined by vacuum (-tight) housing (2) by head lamp and passing lamp two.The filament (1) of described head lamp by reflection shield and after being positioned at focus constitutes, and light boundling after reflection becomes taper directive the place ahead, garden, sees accompanying drawing 1.Described passing lamp is by horizontally disposed filament (3), asymmetric watt of shape reflector (4), globoidal prism (6) and be positioned at horizontally disposed filament (3) grating (5) formation before.The minute surface central authorities of described vacuum (-tight) housing (2) are concavity.The filament (3) of filament of described head lamp (1) and passing lamp is seen accompanying

drawing

2,3 and 4 respectively on the rotational symmetry line of vacuum (-tight) housing (2).

Filament (3) is horizontal linear light source, because the imparity of asymmetric watt of shape reflector (4), first half light becomes divergent shape directive the place ahead after reflection.Described first half light is made up of two parts, and some 11 is directly penetrated radial by filament (3); Another part 12 becomes horizontal after reflection.The vertical surface of these 11,12 equal directive globoidal prisms (6), the far ultraviolet road surface is illuminated in the below of directive optical axis after reflecting (this globoidal prism (6) is actually half of convex lens), sees accompanying drawing 2.Lower part light L, accompanying drawing 3 is seen in direct projection and the partly equal nearby square road surface of directive of reflection.Because light 11 and 12 process lens curve (6) backs are directive optical axises below all, paraphase 180 degree, irradiant upward interface promptly coincides with optical axis.Therefore, the light of light source directive globoidal prism (6) must have one to descend boundary clearly, the setting of grating (5), i.e. purpose for this reason.Because the fluctuation of light, behind (5) first resistances of grating tabula rasa A, and its edge produces diffraction of light, after this diffraction light arrives globoidal prism (6), will cause the emergent light upper bound fuzzy, and slightly sense is dazzle the eyes.Install the second resistance tabula rasa B of grating (5), diffraction light stops that through B then the secondary diffraction is just very little, sees attached Figure 4 and 5 for this reason.

Advantage of the present utility model is that this combined light has kept traditional preceding effect according to the strong long drive of country beam; When meeting, the light of the passing lamp of this combined light becomes sectored light irradiation road surface and scenery, can not produce the sensation of dazzling the eyes to sending a car.This effect helps the meeting of the normal speed of a motor vehicle, saves the energy and the muscle power of chaufeur, saves fuel oil, has reduced the wearing and tearing of tire and ground-surface, has prolonged the vehicle operation life-span.

Accompanying drawing 1 is the preceding according to member principle figure of this combined light;

Accompanying drawing 2 is the passing lamp upper half part schematic diagram of this combined light;

Accompanying drawing 3 is the passing lamp lower portion schematic diagram of this combined light;

Accompanying drawing 4 is the grating action principle figure of this combined light;

Accompanying drawing 5 is this combined light complete schematic;

Accompanying drawing 6 is this combined light structural representation.

Accompanying drawing 6 has provided a specific embodiment of the present utility model.By this figure as seen, vacuum (-tight) housing (2) is an integral structure.The front end sleeve of asymmetric watt of shape reflector (4) is contained on vacuum (-tight) housing (2) the recess step, and the rear end of described asymmetric watt of shape reflector (4) is supported by pole (8).The filament of described head lamp (3) is along vacuum (-tight) housing (2) axis direction setting, the axis normal setting of the filament of passing lamp (1) and vacuum (-tight) housing (2).
