Description
Technical field
The utility model relates to a kind of combination instrument auxiliary lighting apparatus, belongs to auto meter technical field.
Background technology
Along with the development of injection moulding and forming technique, the indexing pate of high-grade combination instrument is just experiencing from plane indexing pate to the transition of 3D indexing pate.And along with the appearance requirement of client to automobile more and more higher, now low and middle-grade automobiles also part have employed 3D indexing pate; 3D indexing pate makes people seem more attractive in appearance than 2D indexing pate, more improves grade.But cost is higher than 2D indexing pate, adopt many on medium-to-high grade automobile so general.But along with the maturation of forming process, cost is than there being certain reduction in the past, so employing 3D indexing pate has increasing trend.
Traditional lighting 3D indexing pate is the same with the technology of 2D indexing pate, is equally also to adopt light-emitting diode direct illumination.By day, do not have floor light, stereoeffect still can be apparent in face of user, but to evening, the just back lighting of instrument, the stereoeffect of 3D indexing pate is just had a greatly reduced quality, just have illumination at scale part, the shaping flanging stereoeffect of 3D is just not reflected.
In view of this, the present inventor, through studying intensively, develops a kind of combination instrument auxiliary lighting apparatus of automobile.
Utility model content
The purpose of this utility model is to provide a kind of combination instrument auxiliary lighting apparatus, adopts 2 light-emitting diodes, makes three-dimensional indexing pate 3D effect more outstanding at night, builds special quality lighting atmosphere.
To achieve these goals, the technical scheme of employing of the present utility model is:
Combination instrument auxiliary lighting apparatus, comprise two light pipes being arranged on combination instrument screen board back, and be arranged on the light-emitting diode of light pipe incidence surface, the position that described combination instrument screen board is corresponding with light pipe exiting surface is provided with sector open, perforate on the light transmission combination instrument support of light-emitting diode, be incorporated in light pipe, light arrives exiting surface carry out total internal reflection in light pipe after, emergent ray is after sector open, scatter on the three-dimensional indexing pate of combination instrument, realize the illumination of three-dimensional indexing pate.
As preferably, described light pipe comprises incidence surface, be connected to the arc reflection section between incidence surface and exiting surface, and for light pipe being fixed on the fixed support on combination instrument, the light that light-emitting diode sends enters into arc reflection section by incidence surface, and all light arrives exiting surface after the total internal reflection of arc reflection section.
As preferably, described incidence surface is circular arc, and its principle is just equivalent to convex lens, and the light dispersed that light-emitting diode can be sent condenses together, and then increases the luminosity of exiting surface.
As preferably, described light pipe is provided with further the first reflecting surface and the second reflecting surface, the light that light-emitting diode sends enters into arc reflection section by incidence surface, all light arrives the first reflecting surface after the total internal reflection of arc reflection section, some directly reflexes to exiting surface, and a remaining part arrives exiting surface after the second reflecting surface refraction.Can by light wire exiting surface as much as possible by two reflecting surfaces.
The light of light-emitting diode arrives light pipe exiting surface after light pipe, emergent ray is after sector open, scatter on the three-dimensional indexing pate of combination instrument, to the glass outer of combination instrument, dazzle is produced in order to avoid light scattering, sector open is set by the bright dipping region at instrument combine screen board, so both avoids light scattering to glass outer, light can be spread out on indexing pate equably again simultaneously, just instrument outline line can be highlighted at night, 3-D effect is given prominence to.Combination instrument auxiliary lighting apparatus described in the utility model by being reflexed to uniformly on three-dimensional indexing pate by the light of light-emitting diode, builds more three-dimensional 3D scale illumination, to the effect of people's more intense impact.

Detailed description of the invention
As Figure 1-4, combination instrument auxiliary lighting apparatus, comprise two light pipes 2 that symmetry is arranged on combination instrument screen board 1 back 13, and be arranged on the light-emitting diode of light pipe 2 incidence surface, the position that described combination instrument screen board 1 is corresponding with light pipe exiting surface 21 is provided with sector open 11.In the present embodiment, described light pipe 2 comprises exiting surface 21, incidence surface 22, first reflecting surface 24, second reflecting surface 25, be connected to the arc reflection section 23 between incidence surface 22 and exiting surface 21, and for light pipe 2 being fixed on the fixed support 26 on combination instrument, described first reflecting surface 24, second reflecting surface 25 is positioned on the opposite face of exiting surface 21, the light that light-emitting diode sends enters into arc reflection section 23 by incidence surface 22, all light arrives the first reflecting surface 24 after arc reflection section 23 total internal reflection, a part directly reflexes to exiting surface 21, a remaining part arrives exiting surface 21 after the second reflecting surface 25 reflects, can by light wire exiting surface 21 as much as possible by two reflecting surfaces.Light carries out total internal reflection in light pipe 2, and arrive exiting surface 21, emergent ray, after sector open 11, scatters on the three-dimensional indexing pate 12 of combination instrument, realizes the illumination of three-dimensional indexing pate.
In the present embodiment, described incidence surface 22 is circular arc, and its principle is just equivalent to convex lens, and the light dispersed that light-emitting diode can be sent condenses together, and then increases the luminosity of exiting surface 21.
The light of light-emitting diode arrives light pipe exiting surface 21 after light pipe 2, emergent ray is after sector open 11, scatter on the three-dimensional indexing pate 12 of combination instrument, to the glass outer of combination instrument, dazzle is produced in order to avoid light scattering, by the bright dipping region at instrument combine screen board, sector open is set, so both avoid light scattering to glass outer, light can be spread out on indexing pate equably again simultaneously, just instrument outline line (G line, H line) can be highlighted at night, 3-D effect is given prominence to.
Exiting surface 21 described in the present embodiment, incidence surface 22, arc reflection section 23, first reflecting surface 24, second reflecting surface 25, and the angle of sector open 11 is all obtained by the adjustment of optical simulation post analysis, strictly follow optic path requirement, ensure that light scattering as much as possible is on three-dimensional indexing pate 12, realizes best 3D illuminating effect.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
