Detailed description of the invention
Fig. 1 and Fig. 2 shows the schematic diagram imitating electroplated structural according to the local of the transparent material of first embodiment of the invention, wherein, the imitative electroplated structural in this local have towards the first surface 1 of observer side, deviate from observer side the second face 2 and between first surface 1 and the second face 2, enter light face.Enter light face to imitate in electroplated structural for allowing extraneous light to inject described local, and reflect on the second surface.In the first embodiment, enter described in light face preferably include deviate from observer side and three face 3 angled with the second face 2.More preferably, enter light face also comprise towards observer side, preferably with arc transition to the fourth face 4 of first surface 1.Alternatively, described fourth face 4 can be seamlessly transit the curved surface to first surface 1.
As shown in Figure 2, incide the incident ray a on fourth face 4, be partly refracted on the 3rd face 3, and reflex on the second face 2, then reflex on first surface 1, reflect the visual field entering people from first surface 1.On the other hand, incide the incident ray b on the 3rd face 3, be partly refracted on the second face 2, then reflex on first surface 1, reflect the visual field entering people from first surface 1.
Keynote idea of the present invention is, when the light seen when observer watches first surface 1 attentively is the light occurring to be totally reflected on the second face 2, just can see stronger light, thus see the effect of similar plating, now, namely first surface 1 presents imitative electroplating effect.When the light seen is the light also occurring to be totally reflected on the 3rd face 3 simultaneously, the light seen when observer watches first surface 1 attentively can be stronger, and thus the imitative electroplating effect that presents of first surface 1 is more obvious.
See Fig. 3, it illustrates the end view of imitating electroplated structural according to the local of the transparent material of second embodiment of the invention.Be with the first embodiment difference, fourth face 4 is relative to the angled setting of first surface 1.
Equally, incide the incident ray a on fourth face 4, and/or incide the incident ray b on the 3rd face 3, after superrefraction and reflection, reflect the visual field entering people from first surface 1.Thus, when there is total reflection on the second face 2 and/or on the 3rd face 3, namely first surface 1 presents imitative electroplating effect, thus observer can be made to think by mistake, and first surface 1 is electroplating surface.
The specific implementation of purport of the present invention is described below in detail for the second embodiment, composition graphs 4.
The total reflection of light has certain condition, for transparent material, wants to reach total reflection on the second face 2, as shown in Figure 4, need meet incidence angle (angle of reflection) θ
3the critical angle C of>=transparent material.For transparent material PMMA (polymethyl methacrylate), its refractive index n is 1.48 ~ 1.50, and the critical angle C of total reflection is 41.8 ~ 42.5 degree.
With θ
1represent the angle between first surface and second, with θ
4represent that observer watches attentively on first surface some time sight line and horizontal plane between angle.The light seen due to observer reflects from first surface, thus the incidence angle θ of this light
2meet sin θ
4/ sin θ
2=n (i.e. the law of refraction of light), so, can determine according to leg-of-mutton interior angular dependence:
(90 ° of-θ
3)+θ
1+ (90 ° of+θ
2)=180 °, so obtain θ
3=θ
1+ θ
2.
As previously mentioned, in order to see imitative electroplating effect, the second face 2 should be totally reflected, that is, θ
3>=C,
So obtain θ
1+ θ
2>=C.
Wherein, C is determined by sinC=1/n, and n is the refractive index of described transparent material, and for the material determined, the value of C is determined.For θ
2, then by sin θ
4/ sin θ
2=n determines, and θ
4then can according to this height h locally residing for imitative electroplated structural
1the height h of (for as the decoration on air-conditioning, i.e. the suspension height of air-conditioning), observer's eyes
2, observer horizontal viewing distance h
4(for air-conditioning, being man-machine horizontal range) is determined, i.e. cos θ
4=h
4/ (h
1-h
2).
Therefore, when determining the angle θ between first surface and second according to above-mentioned condition and parameter
1time, just can determine the light angle scope that total reflection occurs, namely the second face 2 can be totally reflected, thus imitative electroplating effect can be seen when making observer watch first surface 1 attentively.When light intensity is larger, imitative electroplating effect is more obvious, so improve incident light beam strikes scope effectively can strengthen reflecting effect.
Preferably, if the 3rd is also totally reflected, then the light intensity seen of observer is larger, thus is more obviously imitated electroplating effect.For this reason, the angle θ between the 3rd face 3 and the second face 2 should meet θ>=2 θ
3, also, θ>=2 (θ
1+ θ
2).As shown in Figure 4, as θ=2 θ
3time, the 3rd face 3 is totally reflected just, and becomes large along with θ, the angle of reflection on the 3rd face 3 also becomes large, all can be totally reflected within the scope of this.And adjust fourth face 4 and the angle of vertical direction, glancing incidence can be made to be totally reflected after the 3rd to the light refraction of fourth face.
As another preferred version, if all see imitative electroplating effect on whole first surface 1, then excellent decoration effect.For reaching this effect, the cross-sectional length L in the second face 2 can be set
1with the relation of the cross-sectional length L of first surface 1, on the first surface that observer is seen, the light at any some place is from the total reflection light on the second face 2.
For achieving the above object, as shown in Figure 4, when the cross-sectional length of first surface 1 is L, draw two dotted lines from the two ends up and down of first surface, make these two dotted lines all be parallel to the light reflexing to first surface 1 from the second face 2, so cross-sectional length L in the second face 2
1at least should guarantee that the two ends of second all reach or exceed this two dotted lines.
Under critical condition, according to sine, L
1/ sin (90 ° of+θ
2)=L/sin (90 ° of-θ
3), also, L
1/ sin θ
2=L/cos (θ
1+ θ
2), so obtain L
1=Lsin θ
2/ cos (θ
1+ θ
2).
Therefore, for guaranteeing this effect, L can be arranged to
1>=Lsin θ
2/ cos (θ
1+ θ
2).
Like this, in the whole cross-sectional length of first surface, also namely on the whole width dimensions (such as short transverse) that the imitative plating limit of electroplated structural is imitated in described local, all can present imitative electroplating effect.
Imitate electroplated structural when described local and meet above-mentioned condition for the moment, can be totally reflected on the 3rd face 3 and/or in the second face 2 from the light a of fourth face 4 glancing incidence, thus give observer with electroplating effect illusion.
In order to strengthen the imitative electroplating effect that observer sees, preferably, fourth face 4 is arranged as follows relative to first surface 1: can't see described fourth face when observer watches first surface attentively, also, is sheltered from by first surface relative to the sight line of observer.Like this, observer watches described local attentively when imitating electroplated structural, only can see first surface 1, and the first surface 1 seen presents imitative electroplating effect everywhere.
As preferred implementation, first surface 1 can be arranged to parallel with vertical plane, thus is convenient to the determination of all angles.
Preferably, described local of the present invention is imitated electroplated structural and be can be used as decoration on indoor apparatus of air conditioner, thus plays the decoration function to indoor apparatus of air conditioner.In addition preferably, described local is imitated electroplated structural and is arranged on position higher than observer's eyes on indoor apparatus of air conditioner, and also, the direction of visual lines that observer watches attentively when electroplated structural is imitated in described local is oblique top.
Owing to can present imitative electroplating effect under specific viewing angle, therefore described local of the present invention is imitated electroplated structural and partly can be replaced some electroplated decoration part of the prior art, thus reach Simplified flowsheet, reduce costs, the effect such as protection of the environment.
Those skilled in the art will readily understand, under the prerequisite of not conflicting, above-mentioned each preferred version freely can combine, superpose.
Be to be understood that, above-mentioned embodiment is only exemplary, and it is nonrestrictive, when not departing from general principle of the present invention, the various obvious or equivalent amendment that those skilled in the art can make for above-mentioned details or replacement, all will be contained in right of the present invention.
