Embodiment
Below, with reference to accompanying drawing, the invention process form is described.In following example, although to inscape, kind, combination, shape, to be oppositely arranged etc. and to have done various restriction, these only exemplify, and the present invention is not limited thereto.
[example 1]
Fig. 1 is the approximate three-dimensional map of the example 1 RR of the present invention being applicable to the rear combination lamp of automobile.The lamp housing 1 of rear combination lamp RCL is configured to before the lamp body 11 of the shallow discoid in required front shape (rear side of automobile), the front shroud 12 played as optical lens function is installed, in this lamp housing 1, zoning arranges stand-by lamp BUL, side marker light TSL, taillight is held concurrently stopping light T & SL.That is, at the inner face of above-mentioned lamp body 11, corresponding with above-mentioned each lamp BUL, TSL, T & SL, be provided with zoning wall 13, by each region of the above-mentioned each lamp of above-mentioned zoning wall 13 zoning.In addition, each lamp region in lamp body 11 arranges light source 2 respectively.At this, each light source 2 is configured on wiring substrate 21, carry LED (light emitting diode) 22.
Above-mentioned front shroud 12 is corresponding with above-mentioned lamp, and zoning forms red lens 12R, amber lens 12U (not diagram), white lens 12W, these being integrally formed of lens.In addition, at above-mentioned front shroud 12, form the local in the region of above-mentioned red lens 12R in zoning, form the RR3 as object of the present invention.This RR3 is integrally formed in the inner face of front shroud 12 with the state of the multiple RR element 31 of rectangular assortment.Certainly, this RR3 is configured to the illumination light of subsequent vehicle be reflected towards subsequent vehicle at these RR elements 31.
Above-mentioned RR3 makes the ester moulding with transmitance taken on a red color be formed, and Fig. 2 (a) represents stereoscopic figure, and in the drawings, the outside 3a towards downside is formed as even surface, is forming above-mentioned RR element 31 towards the inner face 3b of upside.An angle of regular hexahedron (cube) is set to mountain portion 31m by RR element 31, and the projection of the right angle trigonometry hammer body shape be made up of three faces being summit with this mountain portion 31m is formed, and by it, along inner face 3b, assortment is multiple in length and breadth, forms RR3.Along a direction, the cross sectional shape of this RR3 is blocked as shown in Fig. 2 (b) in direction such as along the mountain portion 31m connecting RR element 31, become the shape that assortment has multiple RR elements 31 of rectangular leg-of-mutton mountain portion 31m, between adjacent RR element 31, the valley 31v that height of formation is minimum.
As the shape of this RR element 31, in example 1, above-mentioned RR element 31 is set to 2mm from valley 31v to the height dimension of mountain portion 31m, by basic courses department's size of RR element 31, in other words, the gap-forming of adjacent valley 31v is 2.5mm.Again, when forming RR element 31 like this, the radius-of-curvature rv of valley 31v becomes 0mm.That is, the mountain portion 31m of connection RR element 31 of the valley 31v of RR element 31 and the crest line of valley 31v are formed as the angular shape being roughly crossed as right angle.In contrast, the mountain portion 31m of RR element 31 makes radius-of-curvature rm larger than the radius-of-curvature rv of valley 31v, at this, is set to certain size in 0.1 ~ 0.3mm scope, thus, makes the shape that the mountain portion 31m of RR element 31 is configured to close to sphere.At this, the ridge line section (can refer to Pm shown in Fig. 4 (a)) extended respectively towards three valley 31v from mountain portion 31m also forms the radius-of-curvature rm identical with mountain portion 31m, therefore, in hereafter illustrating, these ridge line section are included in mountain portion 31m.
The RR3 of this formation is formed by using the red resin of die forming transmitance.As shown in Fig. 3 (a), mould 4 is formed by counterdie 41 and patrix 42, described counterdie 41 comprises the RR element recesses 43 of the rectangular triangular shape for the RR element that is shaped, described patrix 42 inner face is formed as tabular surface, use above-mentioned mould 4, by injecting the injection molding shaping RR3 of red resin in the chamber 44 be made up of counterdie 41, patrix 42.This mould 4, the counterdie 41 especially comprising RR element recesses 43 is not by electrocasting shown in patent documentation 2, but forms the method for the forming face that assortment multiple RR element recesses 43 is formed, the manufacture of so-called direct engraving method by cutting dies material surface.This direct engraving rule such as cutting tool forms RR element recesses 43 in smooth die face, the while of with this cutting, forming face is finish-machined to minute surface.By like this forming face being finish-machined to minute surface, when using this resin mould shaping RR3, the surface of the RR3 of shaping forms even surface, the RR that the transmitance that can be shaped is high.Thus, compare with electrocasting, with low cost and short time mfg. moulding die, and then can manufacture RR.
Such as, as shown in Fig. 3 (b) pattern sectional view, in direct engraving method, when forming the forming face of above-mentioned RR element recesses 43, use leading section 5a to be radius-of-curvature to be the cutting tool 5 of the spherical shape of 0.1 ~ 0.3mm.When cutting the forming face of RR element recesses 43, by making the leading section 5a of cutting tool 5 and the position of mountain portion 31m being equivalent to RR element 31, namely the bottom 43a of forming face connects, and bottom this, 43a is formed as the shape of the radius-of-curvature of the leading section 5a copying cutting tool 5.In addition, by making this cutting tool 5 cut along the dip plane rectilinear movement of RR element recesses 43, the angular shape that the crest line that the top 43b of the forming face corresponding with the valley 31v of RR element 31 is formed as linearity intersects.Certainly, with the outside of the RR3 corresponding patrix 42 paired with this counterdie 41 is formed smooth minute surface.
Use the mould 4 manufactured like this to form chamber 44, by the red resin of transmitance is injected this chamber 44, the shaping of RR3 can be realized.This shaping utilizes injection molding, as as shown in Fig. 3 (a), the bottom 43a of RR element recesses 43 is with above-mentioned radius-of-curvature spherically shape, therefore, when by resin injection chamber 44, compared with the mould being angular shape with bottom 43a, the air in chamber 44 easily flows along forming face, air removing efficiency in chamber 44 is high, very effective to there is space (bubble) in the RR3 preventing from being shaped.In addition, the bottom 43a of forming face is sphere, therefore, compared with angular shape occasion, makes the ejection resistance during RR3 demoulding little, also improve the release property of RR3 after shaping.Fig. 3 (a) is in order to illustrate simplification, and diagram is only shaped the occasion of RR3, but in fact, RR3 is integrally formed with front shroud 12, therefore, and mould structure complexity.
In the RR3 formed, as shown in Fig. 2 (c), from the light of the outside incidence of RR3 after the inner face of RR element 31 is totally reflected, facing 180 contrary directions from the outer of RR3, namely light incident direction penetrates.At this moment, if observe RR3 from the outside, whole that RR3 can be seen brightly, but, the angular shape of valley 31v because in radius-of-curvature being " 0 " of RR element 31, at valley 31v, along the crest line of RR element 31, the wire that dimmed one-tenth is thin.See this wire secretly, identical with RR up to now.But, the radius-of-curvature of the mountain portion 31m of RR element 31 is larger than valley 31v, therefore, as shown in Fig. 2 (c), the part inciding the light of mountain portion 31m through, a part is reflected towards broad range, therefore, the reflected light towards incident direction tails off, the width regions of about two times of the radius-of-curvature of mountain portion 31m, in this example, the region of about 0.2 ~ 0.6mm seems dark.
Its result, as shown in Fig. 4 (a) pattern, at the valley 31v of RR element 31, observes thin-line-shaped dark pattern P v, and at mountain portion 31m, is crossing over the region towards the ridge line section of valley 31v, observes the dark pattern P m of the thick width of Y shape.That is, in the entirety of RR3, the state of the rectangular assortment of dark pattern P m of multiple Y shape is seen.The dark pattern P m of this Y shape is thick width, therefore, even if also can fully depending on recognizing from a distant place, thus, at this RR3, only see the dark pattern P v of the thin width of simple shape from whole face as in the past, become the dark pattern P m of the thick width inlaying Y shape on this dark pattern P v, the aesthetic property of the outward appearance of RR3 can be improved.
At this, if the radius-of-curvature of the mountain portion 31m of above-mentioned RR element 31 is than above-mentioned little radius-of-curvature, then can not expect the effect of the live width of the dark pattern P m increasing Y shape, the visibility of this dark pattern P m is low, and the improvement effect attractive in appearance of RR3 is little.In addition, if the radius-of-curvature of mountain portion 31m is set to than above-mentioned large radius-of-curvature, then effective in the live width increasing dark pattern P m, but, light thus for RR element 31 reflects, and the area of effective reflecting surface reduces, and the reflection efficiency of the light of RR3 reduces.In addition, certainly, the radius-of-curvature of above-mentioned mountain portion 31m changes suitably according to the height dimension of RR element 31 or basic courses department's size difference.
[example 2]
In above-mentioned example 1, for the example making RR be configured to smooth tabular, but, in the RR in car body bight being disposed in automobile, sometimes require that light is reflected in the optical range from the rear of vehicle towards side by RR, the light reflection of RR can be confirmed from this wide scope.Such as, Fig. 5 is the example of the RR3A in the bight, rear portion being disposed in automobile, forms curved from the rear portion of automobile towards side surface direction.Further, at the inner face of this RR3A, multiple RR element 311 ~ 316 is arranged, the direction change of each optical axis x1 ~ x6 of the RR element adjoined in the horizontal direction of each RR element 311 ~ 316.At this, if the optical axis of RR element is defined through the summit in the mountain portion of RR element, is positioned at the straight line of equidistance with orthogonal three faces, then the optical axis x1 ~ x6 of RR element 311 ~ 316 becomes the curve form of following outside RR3A, from the formation that the rear of vehicle little by little changes towards side surface direction ladder.In addition, each RR element 311 ~ 316 is identical with above-mentioned example, and the radius-of-curvature in mountain portion is formed as the sphere larger than the radius-of-curvature of valley.
In the RR3A of this example 2, light incides RR3A from automobile rear from the direction crossing over side surface direction wide region, optical axis x1 ~ the x6 of RR element 311 ~ 316 is towards the direction close to this light incident direction, the above-mentioned light inciding RR3A is reflected towards with light incident direction reverse direction by RR element 311 ~ 316, therefore, the light reflection caused by RR3A can be confirmed.At this moment, in each RR element 311 ~ 316, mountain portion is formed as sphere, therefore, seem the wire of the thick width of dimmed one-tenth towards the part of the range of size required for valley from the mountain portion of this RR element 311 ~ 316, identical with Fig. 4 (a) Suo Shi, the dark pattern of Y shape can be seen.This dark pattern is identical with the dark pattern P m of example 1, and is thick width, therefore, even if also fully depending on recognizing, can improve the aesthetic property of the outward appearance of RR3A with the form different from example 1 from a distant place.
[example 3]
About as example 2, form curved RR, also can be configured to RR3B as shown in Figure 6.In this RR3B, by multiple RR element by along each width regions zoning required for curved surface be several groups, each RR element of same group, the optical axis x1 of such as three adjacent RR elements 311 is towards same direction, make the optical axis x2 of RR element 312 of other several group along curved surface assortment, the optical axis x3 of RR element 313 little by little changes along curved surface ladder.Certainly, each RR element 311,312,313 is identical with above-mentioned example, and the radius-of-curvature in mountain portion is formed as the sphere larger than the radius-of-curvature of valley.
In the RR3B of this formation, incide the light of RR3B from determined direction, reflected towards with light incident direction reverse direction by each RR element of optical axis towards the group in the direction close to this light incident direction.In RR element 311 ~ 313, mountain portion is formed as sphere, therefore, identical with Fig. 4 (a) Suo Shi towards the part of the range of size required for valley from the mountain portion of the RR element carrying out light reflection, can see the dark pattern of Y shape.Especially, in this RR, in the group of carrying out light reflection in whole RR element, observe this dark pattern, therefore, can with example 1, the different form of example 2 improves the aesthetic property of the outward appearance of RR.
At example 2, in example 3, represent that RR forms the example of the curved surface bent along horizontal direction, but RR forms vertically bending curved surface occasion also can be applicable equally.In this occasion, can be constructed so that the optical axis of assortment RR element in the vertical direction vertically changes with a unit or group unit.In this RR, broad range in the vertical direction, can reflect at the light of RR depending on recognizing.Even if the optical axis that for RR bending with vertical direction two direction in the horizontal direction too, can be constructed so that each RR element in the horizontal direction and vertical direction change.
In example 1-3, illustrate that the radius-of-curvature of the valley of RR element is the occasion of " 0 ", but, if the radius-of-curvature less than mountain portion, can differ and be decided to be " 0 ".But if make radius-of-curvature large, identical with mountain portion occasion, in RR, the area of effective reflecting surface during reflected light reduces, and the light reflection efficiency of RR reduces.Again, in the valley of RR, the width dimensions of the dark pattern of observation becomes large, and mix with the dark pattern observed in mountain portion and become miscellaneous, the aesthetic property of RR also can reduce on the contrary.Therefore, need to consider, with the relation of the radius-of-curvature in mountain portion, to set suitable radius-of-curvature.
The present invention is not limited to the RR using the die forming formed by direct engraving, also can be suitable for the RR using the mould formed by electrocasting to be formed.But when by electrocasting mfg. moulding die occasion, the pattern of wants is can the radius-of-curvature in mountain portion of control RR element.
What RR of the present invention was not limited to that example represents is disposed in rear combination lamp RR below, also can be configured to the rear side RR of the side being disposed in rear combination lamp.Again, also can be configured to RR on front side of the headlamp shape all-in-one-piece with vehicle, or with rear side identification light or front side identification light shape all-in-one-piece RR.Further, also as independent RR, the rear RR being with impact damper can be configured to.
The following describes the utilizability in industry.
The present invention can be adopted as the RR that the multiple RR element of assortment is formed.
The present invention is not limited to above-mentioned example, can be out of shape suitably, improvement etc. to it.In addition, the material of each inscape in above-mentioned example, shape, size, numerical value, form, quantity, configuration place etc., as long as can realize the present invention, can adopt arbitrary form, and be not construed as limiting.
