With reference to figure 4-6, the even distribution colorama irradiation that mark 1 is sent by a polychrome irradiation unit, this device comprises a light source 4 that has catoptron, manage 2 in one, an outer tube 3,12, one high reflectance light of 6,11, one diffusion media of catoptron distribution membrane 13 and an electronic device 7.

The pipe 2, reverberator 6 preferably was made of 3M SILVERLUX material in the light that catoptron 6 angle of putting makes it to send from light source 4 was transmitted into.Then, light reflects to propagate in interior pipe by high reflectivity film or sheet 13, and this film is 3M Scotchlamp film preferably, and its feature will be described below.Catoptron 11 is placed on from light source 4 that end farthest and manages 2 in the light reflected back with transmission.

Can be lily band or coating so that meet light generation diffusion on it or the diffusion medium 12 of scattering prolongs along the interior length of tube at the end and penetrates, as shown in Figure 3.Diffusion medium 12 is radially relative with transmittance part or the opening 14 that lengthwise on the wall of interior pipe 2 extends basically, diffusion or scattering can take place when light is run into diffusion medium 12, some light then passes transmittance part 14, remaining by more than 13 reflection of film, run into diffusion medium 12 at last with by transmittance part 14.The diffusion medium can be the pure white band that is layered on or is coated in film 13 inside surfaces.On the other hand, film 13 also can have the cannelure of a placement diffusion medium.

High reflectivity film 13 is a kind of thin and soft and Clear ﹠ Transparent materials, as polypropylene or polycarbonate polymkeric substance, the one side surface is level and smooth, and opposite side is the prismatic groove, and it forms a micro-optics prism along pipe 2 longitudinal extensions at the inside surface of interior pipe 2.The characteristic of this film as shown in Figure 1, it schematically shows photoconductive tube 35 and outer light source 33 that has catoptron.Photoconductive tube 35 is made by the Scotchlamp material, and it has the transparent wall that the outside surface that has groove forms the prismatic face, and this transparent wall is effective total internal reflection surface, and can prevent to be transmitted to the light of conduit downwards from film 13 leakages.Each little prismatic mask has two outward-dipping relative prism facets and is in contact with one another to form V-arrangement.Fig. 2 and Fig. 3 will have clearer demonstration.

With reference to figure 1, light 31 sends from outer light source 33 again, runs into the transparent wall inboard of conduit 35, and (Snell ' Law) law reflects and passes through transparent wall according to Si Naier by this transparent wall light.

If light is to run into a prism facets less than the unspecified angle of inner total reflection critical angle, another prism facets that it will carry out inner total reflection and enter same prismatic face will be if it will get back to the inside of pipe with further transmission by internal reflection again.Light will be reflected when the angle that becomes with tubular axis is spent less than 27.The exact value of angle depends on the refractive index of transparent material.

The effect of film 13 is reflected light and absorption reduced to minimum and transmits.Have been found that for each reflection of each typical light be absorbed as 0.12% and be approximately 1.2% for the clean transmission loss of typical incident angle, therefore, reflectivity is 98.7%.

When light arrive pipe 35 from farthest end of light source 33 time, light is reflected back in the conduit by catoptron 37.

For fear of bigger clean transmission loss, can between interior pipe 2 and high reflectivity film 13, add the surface of a white, as shown in Figure 7.Therefore, may become the light of clean transmission loss by film 13 will be by in surface 15 diffusions of white or the reflection return pipe, and is kept here because of light and to have increased efficient.

With reference to figure 4-7, outer tube 3 is used for making outer tube 3 internally manage 2 rotational positioning mutually in the mode of arbitrary routine around 2, one motor sub-assemblies 7 of interior pipe coaxially again.Outer tube 3 is to constitute (as shown in Figure 6) by a plurality of vertical transmittance (transparent or semitransparent) colour filter section, and any one section all can navigate to that side relative with transmittance part 14.The colour filter section of outer tube 3 can be suitably to be fixed in outer tube, as utilizes transparent coloured insert of flange, or the form of the transparent coloured silkscreen on the different sections of pipe 3.Outer tube 3 preferably is divided into 4 color segment that respectively account for quadrant.Each color segment has different colors, for example green G, and red R, yellow Y, and blue or black B, every kind of color is extended along the total length that is outer tube 3 basically.By this way, light outwards throws from the whole length of mark 1 and makes mark 1 illuminated with a kind of monochromatic light.

When being used for automobile marking, for example, visibility may be not high under daylight by the colorama of filter section R, a Y, G, B transmission, and the common reflection potential of this colorama transmission filter section is very poor, causes under daylight observability very poor.This can all partly effectively overcome transmittance and light reflection by making colored transmissive segments.For example, shown in Figure 12, every section R, Y, G or B be by filter material alternately with 41 and the insertion of look reflecting material be with 43 to constitute.In each 1/4th sections, the selection of colour filter and reflected colour material preferably has approaching color at daylight or when observing night.

If desired, thus an available controller or computing machine control the location of outer tube 3 a kind of desired color section R, Y, G or B exposed, to filter light or reflection light on every side by interior pipe 2 transmittance part.

The placement of light source 4 might not be perpendicular to the axle of interior pipe 2.If there is a catoptron 6 to be in the appropriate location simultaneously light is almost axially reflexed in the interior pipe 2, then any angle orientation all can adopt.Arrange if light source 4 and interior pipe 2 are conllinear basically, then do not need catoptron 6.Catoptron can be used on around light source or the bulb light is focused on basically the direction coaxial or that assemble slightly along pipe with pipe, as schematically shown in Figure 6.Yet the axle perpendicular positioning of light source is better, because easier of light source bulb when changing, and can reduce the axial dimension of system.When luminescent marking is to have more advantage on automobile the time,, and when needs, effectively dismantle or more change the bulb because there do not have enough big space to be used in label side to be approaching.

Fig. 7 is the schematic cross-section of an independent interior pipe, has expressed the path of some light.Only to only the producing and send by transmittance part 14 from diffusion medium 12 of external emission, the film 13 on pipe 2 inside surfaces between diffusion medium 12 and the transmittance part 14 is mainly used to light is evenly distributed rather than allows it directly pass transmittance part 14 along pipe 2 length.After repeatedly reflecting, light is finally run into diffusion medium 12.Those repeatedly do not run into diffusion medium 12 from the light from the diffusion medium that transmittance part 14 is gone out in internal reflection and with being with loss hardly once more, and therefore, last nearly all luminous energy is with loss ground from 14 emissions of transmittance part hardly.

Fig. 9 shown one with similar second embodiment of Fig. 7, in Fig. 9, an opaque pipe 2A, it can be the aluminium extrusion moulding, is used for the mode identical with interior pipe 2.Also some is lined with one deck high reflectivity film 13 to this opaque pipe 2A, and just it also has the not lined part of a cannelure form or can place the lens 8 along pipe 2A length longitudinal extension therein.For fear of the clean transmission loss by film 13, the inside surface of pipe 2A is made white or reflective, thereby so that is kept here in light diffusion by the film transmission or the reflection return pipe 2A.

Lens 8 can design in a known manner, to provide mark 1(are seen Fig. 6) more uniform irradiation from bottom to top and to the light on the lower part of running into mark 1 than the short path length adjustment.Lens 8 can be linear, prismatic, transparent and for example be made up of polycarbonate material.

A kind of diffusion medium 5 also radially relatively is provided with lens 8, and in order to improve the uniformity of light that distributes along length of tube, the width of this diffusion medium can change.This diffusion medium 5 broadens when light source 4 extends when vertically leaving among the embodiment in Fig. 5.As an example, the diffusion medium can be for from 0.43 inch nearest width 5A of light source, greatly about 0.58 inch 5B of width of interior pipe 2 mid-length, and from light source 4 farthest or from the nearest 0.88 inch 5C of width of catoptron 6.The width of this variation can form the curved surface width of a variation by the protuberance diffuse material along pipe 2A length, this can be by the groove or the seam that for example pass through to form an even width on pipe 2A, its edge can be fixed the diffusion dielectric material band that broadens gradually, thereby a band along the protuberance that gradually changes of its length is provided.The purpose of this varying width is to pass the amount of transmittance light partly at the uniform irradiation that edge pipe 2 length are being provided in the big trend of pipe 2A far-end from light source nearer end ratio by correction.

And the lens 8 that are preferably the single entry chip architecture can have two or more lateral part 8A and 8B, these two parts on the both sides that diffused ray projected Fig. 9 center line 16 with at whole mark, for example carrying out more on the mark 1, uniform irradiation is useful.Thereby each lens component 8A, 8B have an inclined-plane for center line 16 makes the anaclasis of sending from the curved surface of diffusion medium 5 with distribute light more equably on mark 1.

In addition,, arrive the bottom then, so the refraction angle of leaving the light of each lens component also can be different because light also must further transmit the top that arrives irradiated target or mark.The method that obtains different refraction angles with the identical lens material is a part of thicker than another part by making, as shown in Figure 9.The another kind of method that obtains different refraction angles is to adopt the lens component of different materials, and therefore, each lens component is actually the lens that separate different with other lens component refractive index.

The incandescent halogen lamp that light source 4 is preferably more superior than fluorescent light.For example when needing lower power, the halogen incandescent lamp of a 20W (incandescent halogen lamp) can replace the fluorescent light of two 20W, and illumination effect is improved simultaneously.This Halogen lamp LED has high strength, thinner light beam, more uniform brightness (top of mark is to the bottom), easily change lamp from behind and need not open bonnet, low expense and few assembly (lamp socket and a lamp, with respect to two lamp sockets of two lamps, ballast resistor and line channel), and need few power input (being that 20W is with respect to 43W).In addition, this lamp produces ultraviolet light, can interact to highlight or to produce special-effect with irradiating surface and fluorescent material.

In addition, can adopt the present invention who has Halogen lamp LED to be prevented at the existing dark letter of whenever bringing out of mark or along the ring of light of the bottom of mark.Here electronic marker adopts yellow point or disk to represent letter, and this point or dish are looking it is to keep yellow under the light that comes from Halogen lamp LED, rather than resembles under the common light that comes from fluorescent light to look it is yellowish green.These advantages of Halogen lamp LED have overwhelmed its shortcoming, and promptly the life-span of Halogen lamp LED is less than the life-span of fluorescent light.

For the ease of approaching, pipe 2 or 2A can be for vertically and cut at diffusion medium 5 places, therefore form two semicircular cylindrical portions, these two semicircular cylinders can be connected by an end ring or cylinder with the diffusion medium together with lens 8, for example can have a gear that can be driven by motor drive on it.

Remove basic vertical surface of irradiation, as shown in Figure 4 outside, irradiation unit of the present invention can be the lighting rod towards the preceding color selected.The also end-to-end layout of a plurality of multicolour irradiation unit of the present invention, as shown in figure 10.Having the figure shows the present invention is applied in the demonstration of automobile terminal point, wherein have a part 51 display automobile line numbers, part 53 display automobile terminal points, also have three parts 54,55,56, its each part all has top described structure, and it shows to have can select one of color R, Y, G, B to add long column.Therefore, number reaches three kinds of color sign indicating numbers of 64 and can be shown, and these yards can be still clearly on the farther distance that can be recognized than letter or number.Obviously, can use arbitrarily a plurality of variation ranges that resemble 54,55,56 part with intensity code.Use this layout, the Guan Zaiqi abutting end links in wishing, these were guaranteed to hold and opened this moment, has a light source or every end that a light source is arranged at an end of pipe.Then, the motor drive that is provided for this layout is acting on outer tube separately, and the transmission of light between pipe in not disturbing.On the other hand, each section can be independently, has light source and motor drive separately.

As shown in this figure, the light that sends from photoconduction obtains increasing by adopting the image enhancement plate, and light distributes and improve, and this image enhancement plate certainly uses together with any type of photoconduction of the present invention.In Figure 11, image enhancement plate 9 is positioned at the both sides of seam 14A, slopes inwardly from canning 1, towards outer tube 3.These plates 9 are catoptrical, and increase the apparent size of the look section of colour tube 3.Thereby these image enhancement plates 9 preferably along the whole length of outer tube 3 vertically stretch and further tube end horizontal expansion outside be exposed on the whole circumference from the color segment of the light of interior pipe 2 or 2A outward-dipping along outer tube.

In another embodiment, image enhancement plate 9 can be outward-dipping from the edge of the transmittance part of the interior pipe 2 that closes on or 2A.Such device also is used in and does not use when producing colored outer tube, strengthens the light by the transmittance part.

Image enhancement plate 9 will help evenly to distribute by reflected light and strengthen the radiation response of the light that passes the transmittance part, and the above-mentioned trimmed book that is reflected is not facing to sign that will be illuminated or demonstration, thereby is easily lost.Therefore this reinforcement plate can capture this light that will be lost.

The chrominance section of head-on watching outer tube and reinforcement plate 9(in Fig. 6 from a left side) the people will see a complete colored rectangles, it is of a size of the outer perimeter of reinforcement plate.When the image enhancement plate is essentially parabolic surface, the above-mentioned image of seeing will be the most remarkable, although flat board has tangible advantage.Be readily appreciated that this reinforcement plate can be made required curved surface, thereby evenly intactly shine sign or object.Therefore, in the utilization of Fig. 4 or 6, the making on its surface can make more light reflex on the zone away from the sign 1 of pipe 2,3, thereby whole sign looks as if the same by the rayed of same intensity.

Figure 14-15 represents an improved device, does not wherein need to change color 15.Here shell 61 comprises a static light guide 63, and its structure can be as the structure among Fig. 7 or Fig. 9, but does not have outer tube or its drive unit, and each end has a light supply apparatus 65, and it comprises a bulb 67 and is used for along the catoptron 69 of photoconduction 63 direct light.Device 65 pivotally is fixed on 71, thus it can, as shown in phantom in Figure 15, outside shell 61, extend, so that more change the bulb 67 when needed easily by opening 73.Conventional locking device (not shown) can be fixed on each light source 65 under its duty, as shown in figure 14.Shell 61 is opened along a side 75.Therefore, by the length decision of light guide 63, can provide the irradiation uniformly basically of the extension of any Len req.

Figure 16 and 17 has represented the modifier of a Figure 14 and 15 shown devices.Shell 161 has the Clear ﹠ Transparent plastics of light-transmissive surface 162 and by opaque coating by a kind of, and as pitch-dark 164, make at the rear portion 163 that covers on the Clear ﹠ Transparent plastics.What place side by side in the inboard of Clear ﹠ Transparent case surface 162 is a flat board or thin slice 164, and they are to make with the used same Transflective material of the described light guide of Fig. 3.Equally, the lining of opaque section 163 inboards of shell 161 is a flex foils 166 of being made by same Transflective light-guide material basically.Flat board 164 and the flex foils 166 common tubular light guides that constitute as above, but its cross section is non-circular.

Each end at shell 163 has a light-emitting device 165.Each light-emitting device 165 all is fixed on the shell 163 by axle 168, thereby shown in Figure 16 left-half, light-emitting device 165 can sway 90 ° so that more change the bulb 167.Light-emitting device 165 can constitute for the support 170 of the curved reflector 172 of paraboloidal by supporting one.Central authorities at catoptron 172 are light bulb holders (generally representing with 174), and bulb 167 can insert this socket.Light bulb holder 174 has the end points that is used to connect bulb 167 and is electrically connected to the contact (not shown) of suitable power supply with end points 165.By this device, when device was in duty shown in Figure 16 the right, bulb 167 generally extended axially along shell 163 together with catoptron 172 thereafter.Therefore, bulb 167 can longitudinally be projected light by 164, the 166 tubular light guides that constitute the inside of shell.

The characteristic of photoconduction as mentioned above, so light when being radiated at the inside of photoconduction with low-angle by to internal reflection.Then, these light that pass shell 163 will be by catoptron 172 reflections at the other end.Therefore, light is propagated in photoconduction back and forth.Some light that is radiated on the thin slice 164,166 may be reflected and spread out of photoconduction by light-guide material.For guaranteeing effect, the inside that centers on the shell 163 of curved surface photoconduction thin slice 166 all is coated with or paints white, thereby any light that may spread out of photoconduction is reflected again conversely or the diffraction light echo is led.On the other hand, transparent outer cover also can be in its outside, painted white under any black or opaque external coating.

Among the embodiment among the former figure, Clear ﹠ Transparent 162 of can have (but might not need) zone of diffuse scattering 176 to extend with shell 161 along its length direction of the middle body of curved surface photoconduction thin slice 166 is radially opposite.

Equally, as shown in Figure 16, it is long that the length of plain film 164 cans be compared to most curved surface thin slice 166, thus curved surface photoconduction thin slice 166 center section of cover housing 161 length only.Therefore, curved surface thin slice 166 only supports the part of plain film 164, and does not support its end 162A, and this end is supported by the white surface 178 of shell 161 inside.The result is, as diffusion area, light almost vertically or with other angle is guided into plain film 164 from this zone at the white portion 178 of each end points of shell.These light can pass plain film 164 and irradiation is provided.
