Description
The present invention relates to a kind of car headlamp, this lamp comprises that a shell with a light-emitting hole, one hide the dust cap of printing opacity of this light-emitting hole and at least one and be arranged in lighting apparatus in this shell.
Car headlamp under the situation of dark or poor visibility, illuminates the road surface of automobile front with it for the traffic safety service.In addition, the automobile that head-on comes just can be found in very big distance by the headlamp of opening it.
Because Automobile Design has a strong impact on the image of automobile, than past more paid attention to equally the design of car headlamp today.So rim condition has been considered in structure of car headlamp and moulding during this, these rim conditions concerning the development and structure of car headlamp, do not have or have only less important meaning several years ago.Because the free profile technology of Hyundai Motor headlamp, the dust cap of conventional structure or diffusing glass can replace with the dust cap of clear glass.But the inside that certainly will cause headlamp so also must be by the design standard moulding, from and produced optical problem.The crust of Hyundai Motor becomes more and more smooth at the headlamp position, has increased the reflecting part of the emitting light flux on transparent dust cap.The deflector of light turns on the decorative panel of the high glaze of often packing in the headlamp, and is mapped to the automobile top from this rising.Under the weather conditions condition of severe, this light causes that driver's what is called dazzles the eyes.
For example known a kind of car headlamp from publication document DE 19,511 164 A1 of Germany, the slit that this headlamp is caused by installation on reflection shield overlaps with an additional reflection shield.Thereby make the observer produce the impression of a continuous reflection shield, so just improved the outward appearance impression of car headlamp.
Also known transition region of going from the head lamp shell to the dust cap is provided with one and hides framework, also improves the outward appearance impression thus with the slit that hides this place's formation.In addition, also can be provided with one and resemble the disclosed insert of German utility model DE 298 22 704 U1.
The objective of the invention is to, propose a kind of car headlamp that causes string purpose light portion that reduced.
This purpose realizes by claim 1,2,9 and 10 described features.Multiple favourable structure and improvement have been proposed in every dependent claims.
According to first solution of the present invention, at least one lighting apparatus on the dust cap of making towards the most handy clear glass or the surface of rear reflector is provided with one deck and goes to the reflecting layer, promptly reduce the reflecting layer of going of reflection, thereby the very big percentage of the light that is sent by one or more lighting apparatus sees through dust cap.
In addition, according to a kind of preferred structure of the present invention, the outer surface of dust cap also can be provided with one deck and go to the reflecting layer.Thereby can further reduce the percentage that reflexes to the light of car headlamp enclosure by dust cap.
According to another kind of solution of the present invention, the surface that the light that is reflected by dust cap in the shell is mapped to is provided with one deck and goes to the reflecting layer, so can make the high percentage of this light pass this surface at least and do not reflect.
This measure both can be used separately, can use with the reflecting layer of going of dust cap again.
Wherein be provided with the reflecting layer and promptly reduce the reflective reflecting layer of going, this goes to the reflecting layer to have λ=425 to 650 nanometers, particularly λ=500 to the spectral region between 625 nanometers and the maximum reflecting rate R=5% of spectrum, preferably R＜1%.
According to a preferred embodiment of the present invention, this goes to the reflecting layer to go to the reflecting layer to form by reducing reflective multilayer.This multilayer goes to the reflecting layer enough to know in other use occasion.
In addition, if the surface that the light of dust cap reflection is mapped to has a kind of reflecting layer of going, then can in this surperficial back absorbing medium be set with respect to the light that is mapped to, it can absorb the most of light that passes this surface at least.
Another kind of solution of the present invention is, dust cap has such absorbing medium, it can absorb the light by the reflection of the reflecting surface of reflecting surface or shell inner cavity, promptly absorbs with certain angle to be mapped to light and/or the reflection on the dust cap part or to deflect into the light of enclosure.
According to an alternative solution, the surface that the light of dust cap reflection is mapped to is provided with absorbing medium, and its absorbs the light of incident and/or makes the light of incident aim at dust cap and/or reflection or deflect into the inside of shell.This solution both can be used separately, can be used in combination with the measure of dust cap again.
This absorbing medium preferably goes to the reflecting layer to form by one deck.This a kind of possibility in reflecting layer of going is that this goes the particle in reflecting layer can locate or locate arrangement or be coated with one deck polarisation and goes to the reflecting layer.Another kind of possibility is that this absorbing medium is made up of some structural details especially prism.
Describe the present invention in detail below in conjunction with some embodiment.
Accompanying drawing is represented:
The car headlamp of Fig. 1 prior art;
The headlamp of Fig. 2 the present invention first solution;
The headlamp of Fig. 3 the present invention second solution;
The headlamp of Fig. 4 the present invention the 3rd solution.
Car headlamp shown in Fig. 1 is made up of a shell 1, dust cap 3 sealings printing opacity, crooked of being made by clear glass of light-emitting hole 2 usefulness of this shell.Be provided with a reflective mirror 4 in shell 1, this reflective mirror reflexes to dust cap 3 to the light 6 that lighting apparatus 5 sends.Most of 6a of this light outwards penetrates.But the fraction 6b of this light reflexes to dust cap 3 and because the curvature of dust cap 3 is mapped to the interior reflecting surface 7 of shell 1.These reflectings surface 7 for example can produce on the reflection shadow shield 8 of regulation aspect the designing technique, and these shadow shields are and for example shown in Figure 1 to be arranged as single parts or as the prolongation of reflective mirror 4.Owing to be provided with this surface 7, upwards and penetrate dust cap 3 by the light 6c perpendicular of these surface 7 reflections.Under adverse weather condition, this light causes that the driver dazzles the eyes.
To cause the light portion of dazzling the eyes in order reducing, but to keep the image of crust and headlamp not change or only carry out nonessential change, proposed various solution.
For example in car headlamp shown in Figure 2, be provided with one deck towards the surperficial 3a of the printing opacity dust cap 3 of at least one lighting apparatus 5 and go to the reflecting layer.Can buy this class at other use occasion and different light transmissive materials and reduce the reflective reflecting layer of going that the reflecting layer makes of going by one.For example trade mark be called IRALIN know, tack is good and wear-resisting multilayer on glass goes to the reflecting layer can both well reduce reflective effect in λ=440 in a kind of generation on glass of low refraction to the whole wide spectral range of 650 nanometers.Go to the reflecting layer can reach similar minimizing reflecting effect with the multilayer that Merlon or the propylene organic matter of a kind of GEDOLIN of being named as 85 are made.Because the outer surface 3b of dust cap 3 is reflection ray also, these light can reflex on the reflecting surface 7 of shadow shield 8, so press Fig. 2, the also additional reflecting layer that is provided with of the outer surface of dust cap 3.
But another kind of scheme is, also can be jointly with as illustrated in fig. 1 and 2 measure, on the reflecting surface 7 of the decorative panel 8 of Fig. 3, but the part on the surface 7 that is mapped to of the light 6b of dust cover 3 reflections is provided with the reflecting layer of going of reducing reflection at least.Be preferably in shadow shield 8 back and the light that passes shadow shield 8 be provided with the medium 9 that absorbs these light.
Another kind of unshowned possibility is, the surfaces 7 of shadow shield 8 itself are provided with medium 9, and its absorbs incident ray or for example goes to the reflecting layer to reflect light in the ideal orientation by a polarisation.
