Abstract
The utility model discloses a double-reflection optical assembly capable of freely realizing upper and lower beam conversion. The double-reflection optical assembly comprises a luminous source and a convex lens assembly, the convex lens assembly is arranged right ahead the luminous source, an auxiliary reflector surface is arranged between the luminous source and the convex lens assembly, the luminous source is fixedly connected with the auxiliary reflector surface, and an upper and lower beam conversion device which is capable of moving along the axial direction of the auxiliary reflector surface and is used for adjusting the distance from the convex lens assembly to the luminous source is arranged between the luminous source and the convex lens assembly. Preferably, the convex lens assembly is fixedly connected with a main reflector surface arranged obliquely. The double-reflection optical assembly has the advantages that the auxiliary reflector surface and the upper and lower beam conversion device capable of moving along the axial direction of the auxiliary reflector surface are arranged between the luminous source and the convex lens assembly, so that upper and lower beam conversion and irradiation distance adjustment can be realized freely, light waste during irradiation at long distance can be effectively avoided, and the brightness of irradiation at short distance can be effectively improved.
Description
Technical field
The utility model relates to a kind of light fixture, particularly a kind of bireflectance optical module that can freely carry out the distance-light conversion.
Background technology
In the prior art, usually be provided with two illuminating lamps according to function in the automobile headlamp illuminator: at a distance lamp and closely lamp.This remote lamp and closely lamp usually all design in advance, so under the situation that the distance between car light and the lens and mirror surface radian do not change, illumination distances and the brightness of two kinds of lamps are all determined, can not change.Therefore, usually need to arrange two light sources, cause waste.After this, progress along with technology, adopt convex lens and arrangement of mirrors to realize that the distance-light conversion under the same light source has not been difficult matter, but, thereupon produced again and only had distance light or two patterns of dipped beam, can not freely carry out distance-light conversion and irradiation distance adjustment according to actual irradiation distance ground needs.Simultaneously, because perfect not to the utmost on the structural design often causing the waste of scattering and disappearing when telecurie irradiation, the inadequate problem of brightness can occur again when irradiation at short distance.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of bireflectance optical module that can freely carry out the distance-light conversion, both can freely realize distance-light conversion and irradiation distance adjustment by the utility model, the light waste in the time of can effectively avoiding telecurie irradiation again and raising irradiation at short distance brightness.
For realizing above-mentioned utility model purpose, technical solution adopted in the utility model is: a kind of bireflectance optical module that freely carries out the distance-light conversion, comprise light emitting source, be located at the convex lens assembly of position, light emitting source dead ahead, be provided with auxiliary mirror surface therebetween, described light emitting source is fixedly connected with described auxiliary mirror surface, is provided with between described light emitting source and the described convex lens assembly to move for the distance-light converting means of regulating spacing between convex lens assembly and the light emitting source along auxiliary mirror surface axis direction.
As preferably, described convex lens assembly is fixedly connected with the principal reflection minute surface that is obliquely installed.
As preferably, described auxiliary mirror surface is the plane that parallels with the central axis of light emitting source, its near an end of convex lens assembly with clinoplain or curved surface towards the convex lens assembly.
As preferably, described principal reflection minute surface is the spherical shell face.
As preferably, described principal reflection minute surface and auxiliary mirror surface are made by plastics or metal material, and its inner surface is coated with one deck electroplating film.
As preferably, described light emitting source is LED lamp or ordinary incandescent lamp.
Compared with prior art, the utlity model has following two aspect advantages: 1. can freely realize distance-light conversion and irradiation distance adjustment.The utility model is provided with the distance-light converting means, and by moving light emitting source along auxiliary mirror surface axis direction, the relative distance size changes the irradiation distance distance between easy adjustment convex lens assembly and the light emitting source thereby get final product.So that the irradiation scope more follow one's bent, to satisfy the lighting demand under the different condition.
2. the light waste in the time of can effectively avoiding telecurie irradiation and raising irradiation at short distance brightness.By setting up auxiliary mirror surface between described light emitting source and convex lens assembly, and the convex lens assembly is fixedly connected with the primary reflection surface that is obliquely installed, so that reduce the light waste when long distance illumination; Light concentrates in the certain limit when closely throwing light on, and has increased light luminance.
3. comprehensive benefit is obvious.The utility model only need be set up a mirror surface in addition with respect to prior art, does not too much increase cost, but greatly improves illuminating effect, more conveniently uses and promotes.
