Abstract

The utility model relates to a novel anti-dazzle safety illuminating device for motor vehicles, which belongs to an illuminating fitting device for electricians. The utility model mainly solves the problems that the energy of the existing automobile lamps is dispersed and not centralized, and a low-beam lamp is still dazzling during meeting to influence traffic safety. The utility model is characterized in that the utility model changes the structure of the automobile lamp, and a curved surface is utilized to reflect, converge and diverge light of different positions; the utility model is composed of a shell type inner surface reflective body which is formed by combining a paraboloid half-inner surface mirror, a spherical half inner surface mirror and a baffle plate; a low-beam light source is arranged on a communal focusing point so as to limit the irradiating height during low beams, and the conversion between a low-beam lamp and a high-beam lamp can be conducted. The utility model can be extensively used in illuminating light fittings for motor vehicles.

Description

Novel automobile no-glare safety lighting fitting

This utility model is the reflective optical principle of a kind of application, and the lamps and lanterns device that the self-propelled vehicle night safe that effectively utilizes luminous energy and can avoid light to make the other side personnel feel to dazzle the eyes travels belongs to automotive field.

At present, though the illuminating lamp that uses on the existing self-propelled vehicle utilizes reflecting condensation, but still the tool distinct disadvantage at first is that car light light has stronger halation, even be converted to passing light, still make personnel on the other side's vehicle or opposite pedestrian feel dazzling and dazzles the eyes; Be that utilizing of luminous energy is insufficient, undesirable again, i.e. scattering light and diffusing causes luminous energy not concentrate, and energy disperses, and is meaningless even is deletrious for safety traffic.This makes chaufeur dazzle the eyes dazzlingly mutually because of the other side's car light when night travel especially meeting, does not see the place ahead road conditions, and easily produces tiredly, has a strong impact on safety traffic.Have, though attempt to address these problems with various passive methods, as wear driver's protective glasses, use the far infrared night vision device even make means such as car light energy increase, all undesirable.

The purpose of this utility model is further concentrated being limited to below the certain altitude of light of light time nearly, make the opposite be in this height with the eyes of the vehicles or pedestrians on top exposure not, avoid the other side to dazzle the eyes, luminous energy disperses not concentrate to solve, degree of utilization hangs down and even more important practical safety issue.

The technical scheme of this utility model (as accompanying drawing) is to utilize in the rotation of reflective optical principle and geometrical curve in the face of from the poly-effect of loosing of the reflection of light of diverse location light source, by 1, the paraboloid of revolution half inner face mirror: 2, bulb; 3, sphere half inner face mirror; 4, the integrated device of baffle part composition, requirement coincides the centre of sphere (is the focus of sphere because of the centre of sphere) of paraboloidal focus and sphere, parabola occupies the bottom, and the passing light light source O that bulb is provided is positioned on this focus, and country beam light source O ' is positioned at coaxial a certain position, its place ahead.Like this, when using passing light, it penetrates the concentration of energy of light, the brightness height, adjust it during installation and face upward and bow, can limit the height of irradiation protection face: also can enlarge illumination zone when switching when using country beam, make chaufeur also can see front upper place and objects such as road sign at a distance clearly.

A in the accompanying drawing, B, C are three typical light paths of passing light light source O; A ', B ', C ' are three typical light paths of country beam light source O '.In addition, can offer bulb mounting hole at its rear portion according to reality.Range of exposures when the baffle plate 4 of black flour is used for enlarging distance light and the light that prevents to reflect the other side's car light.

Compare with the prior art device, outstanding effect of the present utility model is the height that can limit the irradiation protection face when using passing light, eliminates halation, good directionality, concentration of energy avoids car light that the other side is dazzle the eyes during meeting, benefit safety traffic, but switch between while dipped beam and distance light.

The preferred plan that realizes this utility model is by this Figure of description, the manufacturing of similar existing similar device, will except that the sectoral integration injection moulding the bulb 2 or punch forming for refuting shell (also they separately can be made the back links), again its inside face is carried out common smooth mirror surface and handle (baffle plate 4 blackings are to avoid reflective), then along the bulb with front and back two cover filaments of centerline axis to the existing generally use of stable installation, make thereafter that filament is positioned on the focus of this device, will use on its existing self-propelled vehicle of packing into.

Claims

Novel automobile no-glare safety lighting fitting is a kind of self-propelled vehicle night light safety traffic electrician's light fixture device, handoff functionality with distance light and dipped beam, further improve illuminating effect, and can limit the height of irradiation protection face during dipped beam, thereby play and prevent the dazzling purpose of dazzling the eyes of the other side personnel significantly, it is characterized in that: by rotation parabolic half an inner face mirror, sphere half an inner face mirror, a black baffle plate is formed with the existing bulbs with front and back two cover filaments, the centre of sphere overlaps with parabolic focus, sphere is last, parabolic following, all negative cambers are carried out common smooth mirror surface to be handled, the back filament of bulb is positioned on this public focus as the passing light light source, coaxial preceding filament like this, can carry out the switching of distance light and dipped beam as the country beam light source, and when using dipped beam, can fully concentrate and utilize luminous energy, and in conjunction with the height limit the irradiation protection face is installed, avoid making dazzling the dazzling the eyes of the other side personnel and the problem that influences safety traffic; Can enlarge illumination zone when using distance light, function does not subtract yet.
