Description

Reflective sigh

The application is the part continuation application of No. the 08/119th, 291, the U.S. Patent application of the not authorization submitted on September 8th, 1993.

The present invention relates generally to reverberator, more particularly, relate to a kind of modified reflective sigh as the roadside traffic mark.

The appearance of automobile has produced the needs to traffic control device.Originally, every kind of traffic mark was cut into unique shape so that identification.Because electricity is not popularized, the paint sign is used for traffic control.Along with the increase day by day that automobile is used, traffic mark begins to be coated with reflectorised paint so that see night.Originally, reflectorised paint is used on the timber, is used in more durable metal identification then and comprises on the lamination sign.Recently in lacquer, increased glass microballoon, or in plate-like product, added glass microballoon and come the body plan way mark, to increase the mass reflex performance.

No. the 2nd, 379,741, the United States Patent (USP) that adopts the example of beaded glass to comprise to authorize Mckenzie; Authorize No. the 3rd, 065,659, the United States Patent (USP) of Palmquist; Authorize people's such as Mitso Toyama No. the 3rd, 494,912, United States Patent (USP); Authorize people's such as Booras No. the 3rd, 877,786, United States Patent (USP); Authorize people's such as Patterson No. the 3rd, 922,433, United States Patent (USP); Authorize No. the 3rd, 934,065, the United States Patent (USP) of Tung; Authorize No. the 4th, 025,674, the United States Patent (USP) of Mizuochi; Authorize No. the 4th, 082,426, the United States Patent (USP) of Brown; Authorize people's such as Cook No. the 4th, 099,838, United States Patent (USP); Authorize Molari, No. the 4th, 519,154, the United States Patent (USP) of Jr.; Authorize Molari, No. the 4th, 544,586, the United States Patent (USP) of Jr.; Authorize No. the 4th, 555,161, the United States Patent (USP) of Row-land; And No. the 4th, 995,185, United States Patent (USP) authorizing Cheng.

The standing state in present technique field is that pearl is placed on paper or the plate lining and coated with thin stack.The opposite side of paper or plate is coated with special bonding agent, and it is bonded on the aluminium.Further improving is to utilize heat adhesive to improve bonding effect.In this method, aluminium is heated, and paper or plate are bonded in aluminium.Open-air sign utilization is placed on the binding on the metal substrate, and draws information, pattern, symbol etc. or its combination, and (STOP), wrong road (WRONGWAY) for example stop.In case when paste was put, sign had promptly been carried out the preparation of mould printing and drawing.But, when the drawing sign, utilize the lacquer of minimum so that avoid covering reflecting medium.At present, toner or lacquer are to be included in the lamination inner face.But, in heating process, can damage the lacquer on the paste inner face.When installing at the scene also other damage can take place.In the time of on sign being fixed on the sign column, bolt can cut out the slit on lamination.Therefore, steam can enter sign, because the daily fluctuation of temperature, lamination can appear in sign to be peeled off, and sign will be damaged in several time-of-weeks.

Other example of reflection way mark and sign comprises:

(1) United States Patent (USP) of authorizing Woltman discloses a kind of sign the 5th, 050, No. 327, and it has a front, is loaded with the hum pattern literary composition in front.The front is made of one or more picture and text parts and one or more background parts.Picture and text and background parts define the xsect part of sign.At least a portion of at least one in picture and text parts and the background parts be retroreflection with transparent.In general, the picture and text of front and background parts are the readability with the information on the raising sign of contrast colors.The backing member of sign must be transparent, is transparent in the arbitrary at least part of backing member as the part of the transparent part of sign perhaps.As long as this sign is when behind during exposure, than common be identified at night can be in sight better.

(2) United States Patent (USP) of authorizing people such as Balint discloses a kind of highway reverberator for the 3rd, 409, No. 344, and it comprises a hollow housing, and this housing has the roof of prism and end wall peace.This housing is molded around molded in advance inserts, and inserts is in the end wall.Inserts has flat substantially outside surface and a plurality of lip-deep retroreflection prism within it, the axis of prism and the planar shaped of inserts are at an angle, when sign/reverberator is placed on its position again with road surface shape at an angle, thereby be reflected back toward from the light beam of automobile in driver's the eye.

Another example of reflection graphic patterns is No. the 3rd, 772,810, a United States Patent (USP) investing people such as Kupperman.The patent disclosure of Kupperman a kind ofly have the pattern that can discern figure, this figure is molded with reflecting material, forms a substantially rigid body with leading flank and dorsal surface.Dorsal surface forms prismatic surface.Dorsal surface also has bonder, pattern is fixed and is bearing on the area supported.Therefore, the light beam of directive leading flank passes rigid body and is mapped on the prismatic surface, produces the mottled reflection graphic patterns of a tool.Reach reflection graphic patterns leading flank can be printed on information thereon.The patent of Kupperman does not show that information is the part of front part.Therefore,, separate, thereby it may be damaged and the influence of weather conditions with the front part because information has one deck of one's own.Kupperman only utilizes a kind of color, and does not emphasize promptly to produce in the pattern body performance of distinct information.

Another problem of the prior art is on common metal upright post, sign as common parking (STOP) sign to be installed on the U-lag formula column or on the pin.The parking of standard (STOP) sign has two or four holes, and bolt passes the hole, so that sign is contained on the column.The effect of using spanner to tight a bolt can damage bolt, long afterwards can corrosion.Thereafter corrosion soon can influence the sign front again, makes sign seem to seem outmoded.

Though, in this specialty, still lack particularly at obvious suitable traffic mark at night since automobile is used as a nearly century of the vehicles.Therefore, in this specialty needed be a kind of have compare the sign that is easier to the reflection unit seen at night with existing common sign.In addition, this sign should be more durable, can be more more lasting than the sign of present use.Therefore, the present invention is intended to address the above problem effectively and defective.

In general, the present invention relates to plastic construction, have the reflective sigh of a front part and a back side part.More particularly, the present invention has adopted the retroreflection technology.No matter the position of light source makes light return near the reverberator of light source and is called retroeflector (retro-re-flector).From literal, the meaning of retroreflection is, strictly makes every light reverse, sends back to backward along its original path or parallel path.Therefore, desirable retroeflector can make the most of light that receives from a concrete light source turn back to light source itself.But desirable retroeflector can constitute a kind of theoretical limit situation of not having practical value.The difference of practical retroeflector and desirable retroeflector is, makes the light beam that returns be conical, so that reach in observer's the eye.

A kind of retroeflector is the triple reflection device.The triple reflection utensil has the reflecting surface on three planes, arranges to such an extent that make each reflecting surface all perpendicular to other two reflectings surface, for example is similar in the room one jiao of ground of converging and two adjacent walls.Therefore, any will be strictly reverse all from the light of all three face continuous reflection.

Be designated example with parking, the front part is molded with the red pigment of an amount of sign, and literal or symbol area and border keep pure or water-white.Reflection unit such as solid angle are contained in the whole back side of front part.Plastics can add ultra-violet stabilizer, in case pigment fades because of solar radiation.It is opaque that back side part can be actually.The interior lights system of back side part is very bright and clean, can approach specular.The light that passes the front part reflects back by sign, form a kind of effect near the reflection of light, thereby has increased the ability that people see sign in the dark.Recently, sign can be coated with the siloxy group product.This coating can increase scape outside line stability, also makes the sign surface harder, to reduce efflorescence, dust stratification and scuffing.The ability that silicon coating also makes sign more have tolerance to destroy is not because lacquer can be for good and all attached on the processed surface.

Another alternate embodiment of the present invention's sign comprises a front part, and it can be molded as a special information and be combined with reflection unit; An opaque back side part, it provides second reflection unit, and sign is read from the front only; And gap that forms by separation front part and back side part.The size in gap can be by supporting member and the control of sidewall system, supporting member and sidewall are also made by plastics such as polycarbonate or acrylic plastics, they are molded into an optical lens system, and this has strengthened the light that enters sign and has lighted the optical prescription of combination in whole sign (prism of various retroreflections with other surface).In addition, also provide and be used for sign is installed in various embodiment on the common column.

Therefore, an object of the present invention is to provide a kind of at the reflective sigh brighter at night than common reflective sigh.

Another object of the present invention provide a kind of night than the easier reflective sigh of seeing of common reflective sigh.

Another object of the present invention provides a kind of reflective sigh more lasting, more durable than common reflective sigh.

Another object of the present invention provides a kind of reflective sigh with plastic construction.

Another object of the present invention provides a kind of reflective sigh, and it can reclaim fully to make alternative reflective sigh.

Another object of the present invention provides the reflective sigh that a kind of cost is lower, be easy to make.

As shown in drawings, the present invention represents a kind of improved reflective sigh according to following method of moulding body plan.General label be 10 symbol by the two plastic parts body plan, comprise a previous section 12 and an aft section 14.When body plan, preferably use solid but flexible plastics are arranged, as the polycarbonate of MAKROLON or LEXAN board.But the body plan reflective sigh also can use other plastics similar to the polycarbonate characteristic or the combination of plastics and material.The design thickness of front part 12 not only provides rigidity for identifying 10, and the zone that forms solid angle 16 is provided, and solid angle can increase the reflectivity of sign.

Describe the fabrication method (Fig. 1 and Fig. 2) of the sign that needs two kinds of colors now, according to the design of sign, first kind of polycarbonate 20 injects the front region of mould 40 to sign by hole 30 and 32.Specifically, one of plastics of two kinds of colors are injection molding.This will be called first injecting body.Obviously, more than two holes first kind of polycarbonate flow through, the number that uses those holes and hole is the structures shape by sign.Other color distribution zone of sign and the hole end relevant with this zone in the injection moulding process of the polycarbonate of first kind of color by obstruction or separating device 42 shutoff in case first kind of color enter in this zone of structure.After first plastics (polycarbonate) 20 solidify or harden.Handle mould to hold other color or pure plastics.As shown in Figure 2, blocking device 42 is pulled to open hole 34, second kind of plastics can be passed through, and finish the body plan of front part 12.After 20 sclerosis of first kind of plastics, it promptly brings into play the effect of the type of tamper evidence of

hole

30 and 32, thereby does not make second kind of plastics enter the zone of first plastics 20 of structure by

hole

30 and 32 when injection moulding.

Now because first kind of plastic hardening and retracting of blocking device 42 and altered mould 40 admits second kind of plastics 22 to task the front region of the sign of second kind of plastics to fill with branch.This will be called as second injecting body.Only need the plastics of two kinds of different colours in this example, still, obvious this method also can be used for the plastics of multiple different colours, and this will adopt the type of tamper evidence 42 of proper number and the colour or the clear plastic of sclerosis in the past.The colour or the clear plastic that only allow to increase flow into mould according to the sign design at the sign front region of appointment.In such circumstances, the plastics of increase will be called as the 3rd injecting body, the 4th injecting body or the like.When all plastic cool, the front part 12 that identifies 10 is taken out from mould 40.

A kind of alternative method of said method is to take out first injecting body.(plastics 20 of first kind of color after the sclerosis), and it is moved independently second mould, it is used to inject second injecting body (plastics 22 of second kind of color).By two injecting bodies identical basic substance (just pigment difference) is arranged, thereby two injecting bodies fuse mutually, make front part 12 become single finished product.It is molded that front part 12 has an amount of pigment, and literal and symbol region can keep pure, or made by other plastics with contrast color.According to the mould design, there are a plurality of solid angles 16 at the whole back side of front part 12.

But in above-mentioned arbitrary method, mould is designed to be in front that the total inner surface of part 12 forms a plurality of solid angles 16.Though solid angle 16 is preferably disposed on the whole back side of front part 12, the present invention is not limited thereto.Therefore, the big portion at the back side of part 12 but be not all to go up to form a plurality of solid angles 16 in front, this is also within the scope of the invention.Each solid angle 16 is forms of a kind of above-mentioned triangle catoptron.Solid angle 16 is amalgamations of 90 ° of triangular pyramids, and they are that mould structure forms, so that provide good Night visibility for sign.

In case front part 12 is taken out from mould 40, just it is installed on the back side part 14.Preferably punching press in advance or be molded as the correct sign shape of receivability front part 12 of back side part 14.Front part 12 can be installed on the back side part 14 by distinct methods such as clamping, gummed, bonding, interlock, ultrasonic techniques.But the present invention obviously is not limited to these methods of attachment of pointing out, other method of attachment of not pointing out also within the scope of the invention.

At last, the front part 12 of sign 10 is coated with siloxane surface rigidizer 80 and sclerosis.Except front part 12, in order to increase protection to identifying 10, whole sign can be coated with silicone surface hardener 80.The salable sign 10 of silicon coating, and make it avoid the solar ultraviolet influence.Silicon coating also can make the surface harder, makes sign 10 increase the ability that opposing destroys, and keeps its outward appearance bright and clean simultaneously.Therefore, the present invention and tradition sign compare cremasteric reflex better, more durable sign.

As substituting of siloxane, in molding process, can introduce the compound of compliance with environmental protection requirements such as solid plastic metal such as the detackifier of TEFLON or TEFLON, and polycarbonate or acrylic plastics, resist ultraviolet surface quality to increase, or be used as the restraining barrier of surface lacquer and bonding agent.Owing to added one or more in the above-claimed cpd, identified 10 useable solvents and clean, and do not damage the inside pigment that forms identification information, thereby open-air sign is repaired to increase the service life again.In another embodiment, in resin, provide compound, thereby make sign have the crust of siloxane.

Therefore, identify preferably all made of plasticly, do not have paint, bottom layer of aluminum, reflector plate or sticker.Sign 10 whole front part 12 is exactly a sign, and do not resemble the sign of prior art be adhere to metal, timber or even the base plate of plastics on adhesion, identify as STOP etc.The letter of marking structure, symbol and color are come out with plastics (polycarbonate) are molded together, are that the back side is molded into solid angle 16 in the front part 12.Compare with the prior art sign, sign 10 has fabulous reflectivity.In addition, scratch sign 10 and also can not lose reflectivity, because solid angle 16 is in the inboard, employed coating material is difficult for accepting extraneous paint vehicle.

Only be for convenience of explanation, when description is of the present invention, used the example of parking (STOP) sign as the sign design.But from following description as can be seen, the present invention also requires reflexive sign applicable to the body plan any kind of, no matter its shape and color are how.

Be designated example with parking, now describe molding process.(having red) polycarbonate injects mould by the hole.Therefore, molded front part 12 has an amount of red, and the zone that the place gone up in front in literal (STOP) keeps pure.After the sclerosis, pure plastics (polycarbonate) are by the zone at hole injection STOP printed words place, and the borderline region of sign.The red polycarbonate of sclerosis is as blocking up the device of trembling with fear in case positive clear plastic enters these zones of front part 12.The whole interior or back side of front part is molded as solid angle 16.

What in use, pay close attention to most for the sign of stopping is that red pigment will be faded owing to the ultraviolet ray from the sun.But plastics (polycarbonate) have added ultra-violet stabilizer to prevent above-mentioned fading.

In addition, the thickness of front part 12 makes than only having the red pigment of significantly Duoing in common parking (STOP) sign that reflects the red coating of tinting on the adhesion.The pigment that increases also can increase the life-span of open-air sign 10.

The back side part 14 of STOP sign 12 is also used plastics, and preferably polycarbonate is made, and actual showing is opaque.The interior finish of the inside surface 18 of back side part 14 is very bright and clean, almost resembles minute surface, thereby forms reflecting surface.Perhaps, film, machine-glazed paper or the metal level of MYLAR board can be set on the inside surface of part 14 overleaf, so that form reflecting surface.By this way, any light that passes front part 12 all will pass sign and reflect back, thereby form the effect of a kind of approximate " reflective (back lit) ".Therefore, improved the ability that people see sign 10 in the dark greatly.In addition, on sign, also electric light source can be set, to increase the light quantity that reflects back from mirror sample smooth finish surface.At last, whole sign 10 can be coated the siloxy group product.Silicon coating has increased the UV stable of red pigment and polycarbonate itself.Another benefit is that silicon coating makes sign 10 surface harder, thereby reduced efflorescence (chalk-ing) amount, dust and to identifying 10 scuffing.Silicon coating also makes and identifies the tolerance that has destroying, and some paint then can not be for good and all attached on the processed surface.

In first alternate embodiment, reflecting surface (being MYLAR board film, machine-glazed paper or metal level etc.) can be arranged on the solid angle 16 so that special reflection to be provided.After solid angle 16 applies reflecting surface, solid angle can be sealed, thereby need not back side part.

In second alternate embodiment (Fig. 7), solid angle can be arranged on the back side part 14 of sign rather than on the part of front.Therefore, the inside surface of front part and outside surface are flat substantially.Make the method for front part, remove and in mould, be not provided with beyond the cube corner structures, still identical with the description of front.This alternate embodiment has whole advantages of first embodiment of the invention.

In the 3rd embodiment, the front part is pure or water-white, and the inner face of the inner face of back side part or front part contains solid angle.In this embodiment, insert a film with comparatively rigidity of printing or drawing information.As required, japanning can be transparent or opaque.The example of the 3rd embodiment is " speed limit (speed Limited) " sign, and (that is) variation, construction area, " speed limit " can time to time change owing to riving condition.An operator can handle sign, removes information, and with different information substitutions.After finishing the riving condition of change, information originally can be inserted once more, thereby has utilized identification facilities better.To aforementioned similar, can not establish back side part, and reflecting surface is set on solid angle.

Second alternative method of sign design relates to the different colours that uses prefabricated mold shape 50 to separate marking structure.Be designated example (Fig. 7 to 10) with stop (STOP) again, the body plan of prefabricated shape 50 by plastics being injected into a mould, thus profile (for example alphabetical S, the T of letter, pattern or other symbol made according to identifying design, O and P, and the outer border area in the STOP mark).Prefabricated shape provides abutment wall, and the device that separates or separate the used color of marking structure.In this method, above-mentioned separating device 42 because prefabricated shape provides such function inherently, thereby no longer is necessary.

In order to make prefabricated shape 50, plastics are injected first mould, it is used for forming according to the needs of sign design the profile of letter or symbol.The used plastics of prefabricated shape 50 are identical with sign front part 12 used plastics with color.Therefore, plastics form seamless combination with fusion well mutually.Once cooling, and remove residual plastic, shape is promptly inserted second mould to make the front part of sign.

Using stops is designated example, owing to used prefabricated shape 50, red plastic and clear plastic can be injected mould simultaneously.Clear plastic is cast in letter " S ", and " T ", in the partition wall and the zone between the outer boundary 52 of " O " and " P ", red plastic then is cast in the zone 54.In this second mould, main body angle 16 according to aforementioned other method in similarly mode body plan.Solid angle 16 can be arranged on the front part 12 (Fig. 8) of sign, also can be arranged on the back side part (Fig. 7).In the time of on being arranged on front part 12, except that prefabricated shape 50 regions, solid angle is arranged on the total inner surface of front part 12.But should the zone very little, do not influence the reflectivity of sign 10.

Therefore, this second alternative method is a kind of more practical method of body plan reflective sigh of the present invention.In addition, prefabricated shape 50 provides front part 12 has been bonded on additional areas on sign 10 the back side part, has therefore increased to identify 10 rigidity.

In the work of (STOP) sign of stopping, light, the light of headlight for vehicles will impinge upon on the sign as night.Some light can be immediately returned from the redness of (STOP) sign of stopping and water-white or pure regional reflex.But some light do not reflect, but pass the front part 12 of parking (STOP) sign, pass the minute fissure between the solid angle, and are captured between part and the front part overleaf.This light impinges upon on the bright and clean mirror sample inside surface of back side part and reflects and impinges upon on the solid angle.Solid angle makes light scattering on all directions of capturing between back side part and the front part, thereby makes the driver can be easy to see parking (STOP) sign.Therefore, the present invention can make the driver see parking (STOP) sign before approaching stops (STOP) sign, so that stop safely before entering relevant intersection or highway section.In addition, (STOP) sign of stopping has relatively large red pigment owing to it, thereby can keep more permanent redness than traditional parking sign.Because sign can be fully by plastics or thermoplastics body plan, thereby it is callable, thereby can be used for the other sign of body plan once more according to the present invention.The silicon coating that is coated on the sign helps to prevent that sign is owing to factors such as destruction, scuffing, sunlight are damaged.

The present invention can be used for the reflexive any sign of requirement, no matter its size.The present invention can hold any symbol in the front face of sign, comprise letter, can be Any shape and color, or Any shape or color combinations.Therefore, the present invention can be used for any traffic mark or anyly requires reflexive sign.But the present invention is not limited to sign, but can be used for reflexive other object of needs and target.In addition,, description of the invention describes as reflection unit though being used in combination solid angle,, obviously also can adopt other triple reverberators and reflection unit to substitute solid angle.Obviously use feature of the present invention also can carry out other composite design, this also can be within the scope of the present invention.In addition, though the most handy plastic construction of whole sign, this is not determinate, can use other material such as glass, glass fibre or metal yet.

Figure 11 to 15 represents an alternative embodiment of the invention.Figure 11 is that example is represented this embodiment of the present invention with the sign 300 of stopping.But this embodiment of the present invention obviously also can be used for the sign of any kind, and is not limited to the sign of stopping.Similar to other each embodiment of the present invention, sign 300 is as the polycarbonate body plan with plastics.Sign 300 can form by molded or alternate manner, and this is also similar to other embodiments of the invention.Sign 300 also can be used siloxane surface rigidizer or compound, and this is also similar to other embodiments of the invention.

Sign 300 comprises a front part 302 and a back side part 304.Sign can have an information or other indication in 300, as the part of the front part 302 of sign 300.Front part 302 and back side part 304 are separated mutually by a transparent or pure sidewall 308, limit a part 302 in front, the gap area 314 between back part 304 and the transparent sidewall 308.In addition, a transparent supporting member 309 also can be set to help to limit gap area 314.

Sidewall 308 and/or supporting member 309 best and front part 302 whole body plans.But this is not determinate, and sidewall 308 and/or supporting member 309 also can be with the 304 whole body plans of back side part.In addition, sidewall 308 and/or a supporting member 309 can be independent of

front part

302 and 304 body plans of back side part, and the latter is coupled.

Because sidewall 308 and supporting member 309 are transparent, they can make light penetrate the gap area 314 of sign 300.Therefore, pass the means that light that sidewall enters sign 300 gap area 314 forms illumination, make sign 300 more noticeable.This attractive properties significantly improved with the illumination sign at the headlight access failure of automobile or other vehicle in 300 o'clock.

For example, sign 300 is installed on the column that is positioned under the tree.In the morning or at dusk the time, gap area 314 makes available light enter sign 300, makes sign 300 even also very showy in the shadow of the trees.Therefore, low as in the morning or at dusk the time when sun lift-off, in the busiest time of vehicle activity of student's boarding, sign 300 is located in the school zone or its near zone is very favourable.

As mentioned above,, be provided with sidewall 308, also supporting member 309 can be set in order to support and be formed on the gap area 314 between front part 302 and the back part 304.In addition, it is relevant and depend on thereon supporting member 312 one or more other and information 301 also can be set.Gap area 314 makes the people can suitably design the thickness size of front part 302, back side part 304, sidewall 308 and supporting member 309, with form one with similar tradition sign to compare general assembly (TW) less, firmly, the sign 300 of good rigidly, thereby make sign 300 lighter, be easier to carrying.

In addition, but the shape and size Be Controlled of sidewall 308 and/or supporting member 309 and molded, thus form optical lens 313 and 315 (Figure 14) respectively.As shown in figure 14,

lens

313 and 315 can restrain and disperse and pass the light that sidewall 308 enters gap

area 314.Lens

313 and 315 also can form combination or compound lens, so that form the effect that needs in sign 300, as shown in figure 14.In addition,

lens

313 and 315 can have the prescription of disperse light in sign 300.

Sidewall 308, and supporting member 309, front part 302 and back side part 304 can be provided with exterior finish, makes it can be used as light pipe 311, with the optical prescription of igniting.In supporting member 309, sidewall 308, front part 302 and/or back side part 304, use fluorescent pigment can make sign 300 more showy when sign uses the light of penetrating thereon to light optical prescription.Sign 300 is used the inside light pipe performance of optical lens effects and plastics, so that light is caused privileged site in the sign 300.Therefore, light can be introduced into sign 300, and can be used for the position that activating fluorescent pigment carries out particular job in 300 in sign and propagate, and above-mentioned work includes but not limited to: (1) illuminates the profile of whole sign; (2) only light in the information 301 the letter or other indication; (3) only light in the information 301 profile of letter or other indication; (4) place to the letter in information 301 or other indication strengthens fluorescent effect.Therefore, the present invention is relevant with above-mentioned phenomenon can to use large-scale plastic body, comprises front part 302 and back side part 304.

The use of above-mentioned pigment, from being located at the internal reflection of second reflection unit on the back side part 304, and gap area 314 makes light enter ability that sign reaches the specific region of sign 300 further to have increased and identify 300 noticeable property.Because sign can utilize operational light as the light from the sun, the moon, indoor lamp, street lamp etc., thereby need not the light from headlight for vehicles.In addition, owing to set up low power sources, can make sign 300 or identify 300 several portions luminous.
