Description
Technical field
The utility model relates to road safety technical field, relates to more specifically a kind of LED luminescent road traffic mark board.
Background technology
Road signs are applicable to highways and streets, square, Public Parking etc. for the current place of the public, are to road user transmission of information, for the facility regulating the traffic with color, shape, character, figure etc.What generally use at the road and traffic sign plates of conventional traffic management applications is reflect type sign board, is characterized in the time of the irradiation of extraneous light light along direction of illumination back reflected, thereby reaches reflective effect.Tradition reflect type road and traffic sign plates is in the time irradiating with the larger extraneous light of axis relative angle perpendicular to sign board plane, and reflection ray is decay extremely; In the time not having the irradiation of extraneous light or light weak, traffic sign itself can present as dark as a stack of black cats, thereby causes the effectively content on identification traffic sign of human eye; In highway and urban transportation field, only open high beam at vehicle, when automobile front lamp light is radiated on Reflecting traffic marking board, driver relies on the effectively content on identification at night road and traffic sign plates of light reflecting, and in the intensive urban district of urban population steering vehicle, relevant laws and regulations do not allow to open high beam and travel under normal circumstances, can cause serious light pollution owing to opening high beam, human eye is produced serious dazzle and likely causes great traffic accidents; And light source life is shorter, in the time of light source fails, cannot play the effect of good identification; In the time of large-area displays, cannot effectively take into account whole flat luminous uniformity coefficient and have obvious shade; Cannot quick-replaceable LED luminous lamp strip, complex operation while changing the light-emitting component damaging, need open more structure member and could change, thereby cause the field maintemance used time longer, easily causes unnecessary traffic jam; Adopt the LED lamp bar of the luminous road and traffic sign plates of LED lamp bar irradiation light guide plate not take into full account the heat radiation requirement of lamp bar, cause LED lamp bar because of the bad normal service life that shortens that dispels the heat;
The light-passing board of the road and traffic sign plates of tradition internal illumination adopts screw to be fastened on general frame, owing to there is no reserved gap of expanding with heat and contract with cold, causes the distortion of product integrally bending.
Tradition adopts luminous its light guide plate of road and traffic sign plates and the light penetrating panel of light guide plate to fit together, and is applicable to small-sized luminous sign, and sign board as larger in area cannot keep light-emitting surface brightness even; And to adopt between the metal base plate of the luminous road and traffic sign plates of light guide plate and light guide plate be together fastened to each other, easily produce and be out of shape because of the different product integrally bendings that occur of thermal expansivity; Light guide board fixing structure is not reserved space of expanding with heat and contract with cold also; Light guide plate does not have rubber mount sealed damp-proof when fixing; In the time making large-scale sign board, there is the difficult problem of processing assembling.
Utility model content
The purpose of this utility model is exactly the deficiency in order to solve prior art and the one that provides is simple in structure, is convenient to the LED luminescent road traffic mark board that assembling is safeguarded.
The utility model is to adopt following technical solution to realize above-mentioned purpose:

Light-passing board of the present utility model adopts hollow transparent sheet material, has increased light guide plate to the distance between printing opacity and reflective film, has effectively improved the shadow problem that between light emitting module, modular construction forms; Hollow board material provides maximum structural strength in the case of using the material of same units weight, has good energy conservation and consumption reduction effects.
The utility model is installed aluminium groove end plane and is had many light reflection grooves, is conducive to improve the shadow problem between light emitting module.
Between light guide plate of the present utility model and fixed groove, there is certain reserving gaps, solved between light guide plate and base plate because thermal expansivity is inconsistent, and the sign board integrally bending causing is out of shape serious problem.
Light-passing board of the present utility model adopts hollow board material, because the structural thickness of hollow light-passing board itself is lower, has and absorbs the performance of local bending distortion and reduce the negative effect that light-passing board entirety is expanded with heat and contract with cold, and improves the phenomenon that sign board integrally bending is out of shape; Between light-passing board and section bar, adopt the sticking double faced adhesive tape of high-strength weather-proof to fix, have that lightweight construction, intensity are high, the simple feature of production technology.
Between base plate of the present utility model and aluminium groove, add soft sealing strip, played the effect of sealing, waterproof, for light guide plate, the LED lamp bar of base plate front end provide necessary protection.
Between light guide plate of the present utility model and fixed groove, add soft sealing strip, effectively reduced the destruction of extraneous vibration to light guide plate, extended the serviceable life of light guide plate; Between light guide plate and fixed groove, add soft sealing strip, played the effect of sealing, waterproof.
The utility model is installed many parallel grooves that aluminium groove has, play the effect that core texture connects, aluminium groove is installed and has been connected main structure member, comprise base plate, light guide plate, hollow light penetrating panel, while is as the good radiator of LED lamp bar, and the heat of LED lamp bar is transmitted on aluminum alloy bottom plate, make the back of monoblock road and traffic sign plates all as the radiator of LED lamp bar, extend greatly the serviceable life of LED lamp bar.
The utility model installation aluminium groove rear end has the structure of the groove shape structural similarity of installing with traditional road and traffic sign plates, as and stilt between the fixing bridge of installation, make installation of the present utility model and traditional road and traffic sign plates that indistinction is installed, greatly facilitate installation.
