Description

Inclined headlight of automobile with antidazzle function

The utility model belongs to a kind of head lamp in the car headlight device, is applicable to various power actuated vehicles, is particularly useful for the stream line pattern super car.

The normally used head lamp of current China automobile is made up of bulb (two filament), catadioptre and Lens, and its two filaments produce distance light and dipped beam separately, to satisfy night travel and meeting lighting requirement.But these traditional head lamp fwd light-distribution lens are substantially perpendicular to the vehicle body longitudinal axis, can not reduce air resistance well, and use is restricted.

The no-glare scheme that China's utility application number 86210753 " polarized light train crossing jacklights " and application number 88211610 " anti-dazzle apparatus " are proposed is feasible technically, and it is used the polarized light principle and has solved the problem that dipped beam is dazzle the eyes.Its shortcoming is because light quantity loss is bigger, has two kinds of functions of distance light and dipped beam simultaneously and be difficult to realize on a light fixture, and main is that it is inconsistent with the traffic law of domestic and foreign current, is difficult to popularization.

Modern automobile design requires the speed of a motor vehicle more and more higher, has air dynamic behaviour usually, guarantees the stream line pattern of vehicle body simultaneously, so the moulding of the designing requirement of head lamp and vehicle itself will adapt, and requirement is designed to various tiltings with head lamp.

By optics as can be known, the light-distribution lens of head lamp is once tilting will make light to produce deflection, and the light that influences head lamp distributes.Can ignore when its leaning angle is less than 10 ° usually, but modern automobile is designed, and some special formed leaning angle of head lamp that requires reaches 45 °, therefore causes the deflection of light to seem more outstanding, distance light is not concentrated, shortcoming such as the dead line of dipped beam is unintelligible.This photometric standards to head lamp is unallowed.The purpose of this utility model is exactly to solve the inclination of light-distribution lens from the 10-45 ° of light offset problem that scope produced, and satisfies the luminous intensity distribution performance requirement of head lamp.

The utility model has three kinds of inclination modes promptly: hypsokinesis inclined (Fig. 1), lean forward inclined (Fig. 2) and inclination inclined (Fig. 3), the optical system of the head lamp of these three kinds of inclination modes constitutes by bifilar bulb 1, the secondary rotational paraboloid mirror 2 of standard specification, the light-distribution lens 3 that degree of dip is arranged, specific shade 4, dip filament 5, headlight high beam filament 8, the screened housing 6 that special angle is arranged, reflector focal point F7.

Action principle of the present utility model is realized by bulb 1 catadioptre 2 and 3 combineds action of bevelled light-distribution lens.As shown in Figure 1, the dip filament 5 of bulb 1 is placed preceding certain of reflector focal point F7, make it to produce convergent beam.For removing upwards reflected light is equipped with special angle below filament 5 screened housing 6,, a "cut-off"line is clearly arranged through this cover shielding back generation cut-off region.But sometimes owing to limit by the accuracy of manufacture of catadioptre, opening at catadioptre produces stretching Zhe crape, and reflected light is exerted an influence, and causes III district light leak etc., therefore in design, increase a shade 4, be used to eliminate spuious reflected light and part direct light.When the position of dip filament 5 once determining that the position of headlight high beam filament can be determined.In the time of can thinking that the centre of luminescence is on the focal point F 7 of catadioptre, can produce collimated light, therefore require some zone on the light-distribution lens corresponding with some zone on the catadioptre, the design of some refractive power unit also will be satisfied the requirement of distance light and dipped beam for this reason.

Be to realize above-mentioned requirements, require that in force light-distribution lens is pressed into smooth outer surface with mould and, and inside face is made and had as Fig. 4, Fig. 5, each regional cylindrical mirror of light-distribution lens shown in Figure 6 and the fabricate block of prism with vehicle.

Fig. 4, Fig. 5, Fig. 6, be the division of light-distribution lens main region.Among the above-mentioned figure 9,9a, 10,10a, 11,11a zone be to satisfy prism district and the cylindrical lens area that distance light satisfies dipped beam again, 12,12a, 12b aim at the cylindrical lens area that satisfies distance light.

Fig. 4 a, Fig. 5 a, Fig. 5 b, Fig. 6 b are the constructionals drawing of refractive power unit in the above-mentioned zone, and it can make light by predetermined direction deflection, is used to revise the defective that causes light deflection owing to the inclination of light-distribution lens.

The version of the refractive power unit of the division of these prism region is several optimizing structure of the present utility model, be applicable to garden shape, rectangle, the special-shaped tilting head lamp of all size, be characterized in the distance light far firing range, dipped beam has "cut-off"line clearly, and desirable anti-dazzle effect is arranged when the intersection car.With traditional its advantage of head lamp comparison be: can reduce air resistance, energy savings, employed " E " type bulb and " H ₄" the type bulb is interchangeable; Do not increase productive costs; If simplify the head lamp that can change into traditional form a little.
