Below in conjunction with specific embodiment, specific implementation of the present invention is described in detail:
Fig. 1 shows the structural representation of the variable color bright dipping light fixture that the embodiment of the present invention provides, and Fig. 2 shows the structural representation of the light modulation prism of variable color bright dipping light fixture, for convenience of explanation, only shows the part relevant to the present embodiment.
As Fig. 1,2, this variable color bright dipping light fixture is a kind of light fixture that can realize any switching of two kinds of colors, and in the housing of this light fixture, 1 is provided with a reflector 2, and reflector 2 has a light inlet 21 and a light-emitting window 22.At light inlet 21 places, be provided with a light modulation prism 3, in the light inlet side of light modulation prism 3, be provided with two light sources that can send different color light, i.e. the first light source 4 and secondary light source 5.Light modulation prism 3 comprises reflecting surface 31 and the exit facet 32 near reflector 2 and angled docking, and away from first plane of incidence 33 and second plane of incidence 34 of reflector 2 and angled docking.The first 4 of light sources are arranged at the light inlet side of first plane of incidence 33, and secondary light source 5 is arranged at second plane of incidence 34 away from the light inlet side of reflector 2 one sides.Wherein, reflecting surface 31 and the angled docking of exit facet 32, and then form a folding face, equally, first plane of incidence 33 and the angled docking of second plane of incidence 34 have formed another folding face, and these two folding faces are relative, relatively outwards outstanding in the middle of it, relatively inwardly shrink on both sides, makes the shape that light modulation prism 3 is outstanding in the middle of being, shrink on both sides, along the similar rhombus in longitudinal section of the central axis direction of reflector 2.The first light that above-mentioned reflecting surface 31 can send the first light source 4, to the second plane of incidence 34 reflections, can be specifically a kind of mirror reflection surface; Second plane of incidence 34 in the future the first light of self-reflection face 31 reflects to exit facet 32, and the second light simultaneously secondary light source 5 being sent is to exit facet 32 transmissions.Specifically can one deck be set on second plane of incidence 34 can reflect the first light, the second light is carried out to the filter membranous layer 341 of transmission, realizes the function that different color light is carried out to selective reflecting and transmission by this rete.Certainly, can also adopt other modes to realize to the first reflection of light with to the second optical transmission.
As Fig. 3, the operation principle of this light fixture is as follows: the first light source 4 sends the first light, this the first light is injected light modulation prism 3 and is arrived reflecting surface 31 through first plane of incidence 33, reflecting surface 31 reflects the first light to second plane of incidence 34, second plane of incidence 34 in the future the first light of self-reflection face 31 reflects to exit facet 32, this the first light is finally injected reflector 2 through exit facet 32, and a part of light wherein reflects away through reflector 2, and another part light directly penetrates.Secondary light source 5 sends the second light, and the second light is injected light modulation prism 3 through second plane of incidence 34, directly through exit facet 32, injects reflector 2, and wherein a part of light reflects away through reflector 2, and another part light directly penetrates.
The embodiment of the present invention arranges above-mentioned light modulation prism 3 at light inlet 21 places of reflector 2, the light of two kinds of different colours can be penetrated through same exit facet 32 and light-emitting window 22, when carrying out color switching, two kinds of coloured light go out optical position and bore is consistent, avoid conventional lamp not good and the disconnected problem of erroneous judgement occurs owing to going out visual experience that the sudden change of optical position causes when color is switched, effectively improved illumination and the signal designation effect of light fixture.
Be appreciated that this light modulation prism 3 also comprises Liang Ge side 35, respectively between the folding face of reflecting surface 31 and exit facet 32 formations and the folding face of first, second plane of incidence formation, as Fig. 2.Zhe Liangge side 35 can be parallel, also can be not parallel, can not affect dimming effect.Further, the two ends of this light modulation prism 3 can be punctured into a line, also can be punctured into a narrower end face 36, be that reflecting surface 31 and first plane of incidence 33 can extend to the two and intersect, form straight line (not shown), also can be non-intersect, form above-mentioned end face 36, two end faces 36 of prism equally can be parallel or not parallel, can not affect dimming effect.Certainly, two sides 35 and two end faces 36 are all preferably and are parallel to each other, and are convenient to manufacture and assembling.
In embodiments of the present invention, light modulation prism 3 can be one-body molded, is convenient to manufacture.Can also be formed by two prisms (the first prism 301 and the second prism 302) docking.As Fig. 4,5, wherein, above-mentioned reflecting surface 31 and first plane of incidence 33 are one group of relative face of the first prism 301, and exit facet 32 and second plane of incidence 34 are one group of relative face of the second prism 302.Meanwhile, the first prism 301 also has shape and the rear complete light modulation prism 3 that forms of big or small identical ，Liang bottom surface docking that the first bottom surface 3011, the second prisms 302 have 3021, the first bottom surfaces 3011, the second bottom surface and the second bottom surface 3021.And can form a narrow space 303 between ，Liang bottom surface.
The more integrated prism of light modulation prism of this combining structure has the higher efficiency of light energy utilization, details are as follows: the light that secondary light source 5 sends is injected after light modulation prism 3, have the light that the small part angle of divergence is larger and arrive the second bottom surface 3021, if this prism is structure as a whole, light can directly make progress propagation and inject reflecting surface 31, this part light cannot penetrate light fixture, existence due to the second bottom surface 3021 and space 303, have part light, at 3021 places, the second bottom surface, total reflection occurs, and then be reflected to exit facet 32, this part light is effectively used, and then improved the utilization rate of luminous energy.
As further improvement of this embodiment, can limit the angle of inclination of the first bottom surface 3011 and the second bottom surface 3021, making to be mapped in the light on the second bottom surface 3021 has more light that total reflection can occur.Concrete, the first bottom surface 3011 and the second bottom surface 3021 can relative reflector 2 central shaft at an angle, and the distance of the first bottom surface 3011 and the second bottom surface 3021 and central shaft increases gradually along the light direction of reflector 2, the central shaft that deviates from reflector 2 along light direction is outward-dipping, the situation that is parallel to central shaft than two bottom surfaces, the incidence angle that light incides the second bottom surface 3021 is larger, and the light that total reflection occurs is more.
Preferred ，Gai angle of inclination can be 15 ± 3 °, and more preferably 15 °.If this angle too small, is difficult for total reflection occurs, although increasing, angle more easily there is total reflection, can reduce the area of second plane of incidence 34, also can reduce the light that the second light directly arrives exit facet 32, be unfavorable for equally the output of light.
In addition, can also one deck be set on the second bottom surface 3021 to the transmission of the first light, the optical film 3022 to the reflection of the second light, as Fig. 6.Like this, when the part that in the second light, the angle of divergence is larger is mapped on the second bottom surface 3021, can be reflexed to exit facet 32 by optical film 3022.Certainly, the first bottom surface 3011 and the second bottom surface 3021 be the preferred inclined with respect to reflector 2 still, to guarantee that the second bottom surface 3021 can better reflex to exit facet 32 by the second light.
Further, the first light source 4 in the embodiment of the present invention and the distance between first plane of incidence 33 can be less than the distance between secondary light source 5 and second plane of incidence 34.Because the propagation path of the first light in light modulation prism 3 compared with the second light the propagation path in light modulation prism 3 long, propagation path is longer, the degree of divergence of light beam is larger, therefore, may therefore there is difference in spot size and the angle of emergence that the first light and the second light arrive exit facet 32, the position of the first light source 4 and secondary light source 5 is carried out, after above-mentioned design, can addressing the above problem to a certain extent.
In embodiments of the present invention, the structure of reflector 2 can be determined according to the required beam shape of reality, can be specifically circular, and emergent light is circular light beam, is applicable to signal lamp.Certainly can also be square or bar shaped etc., needn't strictly limit herein.
In embodiments of the present invention, the first light source 4 and secondary light source 5 can be any two kinds of light sources without color, because the light of the different colours refractive index in same medium is different, therefore, color according to actual needs further limits the structure of each optical surface of light modulation prism, two kinds of coloured light be can reach with the object of same angle outgoing, and then visual effect that traditional variable color lamp causes due to the angle of emergence difference of different color light and the defect of illumination and signal designation weak effect improved.
The embodiment of the present invention is red light sources for the first light source 4, and secondary light source 5 is that the situation of green light source further limits the structure of light modulation prism.As Fig. 7, exit facet 32 is parallel with first plane of incidence 33, and sharp angle α 1 and α 2 that the two becomes with the central shaft of reflector 2 are 75 °, and the sharp angle α 3 that reflecting surface 31 becomes with central shaft is 68 °, and the sharp angle α 4 that second plane of incidence 34 becomes with central shaft is 77 °.That is, the angle of reflecting surface 31 and exit facet 32 is 143 °, and the angle of first plane of incidence 33 and second plane of incidence 34 is 152 °.It is more than the design that the refractive index in light modulation prism 3 is carried out according to ruddiness and green glow, by the angle of inclination of each optical surface is carried out after above-mentioned design, the angle of emergence of ruddiness after propagation path (first plane of incidence 33-reflecting surface 31-the second plane of incidence 34-exit facet 32), consistent with the angle of emergence after green glow process propagation path (the second plane of incidence 34-exit facet 32, or second plane of incidence 34-the second bottom surface 3021-exit facet 32).Certainly, the present embodiment needn't strictly be confined to above-mentioned angle, and each angle is adjustable in the scope of ± 2 °.After above-mentioned design, visual effect that the angle of emergence difference due to different color light causes and the problem of illumination and signal designation weak effect have been solved.
Certainly, first, second plane of incidence in the embodiment of the present invention and reflecting surface 31 and exit facet 32 angle of inclination are not limited to above-mentioned angle, when Practical manufacturing, can to above-mentioned angle, carry out appropriate design according to the default light color that goes out, to reach the consistent object of rising angle.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
