Abstract
The invention discloses a light-emitting diode (LED) luminous road sign, which comprises a light guide plate, wherein one side of the light guide plate is provided with a transparent plate; a reflective film with a road sign is attached to the transparent plate; an LED light source is embedded into the light guide plate; the other side of the light guide plate is provided with an aluminum plate; the reflective film is arranged between the aluminum plate and the light guide plate; and a diffusion film is arranged between the transparent plate and the light guide plate. According to the LED luminous road sign, a driver can see the traffic sign clearly under the condition of vehicle clamp irradiation, and the driver can clearly see the traffic sign under the condition that an external lamp source is absent.
Description
Technical field
the present invention relates to a kind of road Warning Mark board.
Background technology
The luminous road sign of
existing LED face; Front position in the bottom is provided with organic LGP; The front end of organic LGP is provided with panel; Panel is provided with road signs indication film, indicates the outer periphery of film to be equipped with peripheral protective layer at described base plate, organic LGP, panel and road, and the inwall that faces the peripheral protective layer of organic LGP is provided with several led light sources.Work as opening power, LED lights and through LGP light is spread out of.But the luminous road sign of this LED face has two serious defectives.
at first owing to only a spot of led light source is installed, the refraction of the light that LED produces through LGP passes and has a large amount of losses, make transmit distance can not be too far away.Make that at country and highway, the driver can not just observe a long way off.
secondly owing to just LED is installed in the periphery of LGP, for traffic indication board be have circumscribed.Because at different roads, the speed of a motor vehicle of requirement is different, the size that sign board adopted of so same content is different.Be the speed of a motor vehicle fast road, the size of sign board just requires corresponding increasing.Still can not increase light guide effect and install led light source additional around the LGP behind the large-area sign board.
Summary of the invention
the present invention seeks to: a kind of LED is provided luminous road sign, both can the driver was seen clearly traffic indication board having under the situation of car light irradiation; Also can under the situation that does not have external lamp source, the driver be seen clearly direction board.
technical scheme of the present invention is: the luminous road sign of a kind of LED; Comprise LGP; One side of said LGP is provided with transparent panel, posts the reflective membrane that has road sign on the said transparent panel, and said LGP has been embedded in led light source.
are preferred, and the opposite side of said LGP is provided with aluminium sheet.
are preferred, are provided with reflectance coating between said aluminium sheet and the said LGP.
are preferred, are provided with diffusion barrier between said transparent panel and the said LGP.
Advantage of the present invention is:
1. the present invention are embedded in led light source in the LGP, rather than in the periphery of LGP LED are installed, and have solved the limitation that traffic board size difference is brought.
2. the present invention are pasted one deck reflective membrane and are made the light that passes the LGP rear portion change direction at the LGP rear portion, reflect, and light is all gone out through the LGP front portion.
3. the present invention are provided with one deck diffusion barrier in the LGP front portion, make through the anterior light of LGP, reflect away uniformly, and making light is not single direct light, has both increased luminous flux, makes light not too dazzling again.
4. the present invention both can make the driver that traffic indication board is seen clearly having under the situation of car light irradiation; Also can under the situation that does not have external lamp source, the driver be seen clearly direction board.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is a structural representation of the present invention.
wherein: 1, reflective membrane; 2, transparent panel; 3, diffusion barrier; 4, led light source; 5, reflectance coating; 6, aluminium sheet; 7, LGP.
Embodiment
embodiment: as shown in Figure 1; The luminous road sign of LED comprises LGP 7; One side of said LGP 7 is provided with transparent panel 2, posts the reflective membrane 1 that has road sign on the said transparent panel 2, and said LGP 7 has been embedded in led light source 4.
The opposite side of
said LGP 7 is provided with aluminium sheet 6, is provided with reflectance coating 5 between said aluminium sheet 6 and the said LGP 7, is provided with diffusion barrier 3 between said transparent panel 2 and the said LGP 7.
Principle of work of the present invention is following:
are embedded in the led light source 4 in the said LGP 7, send light and reflect away through LGP 7.The light of to the reflectance coating 5 of bedding on aluminium sheet 6 refraction being come when light reflects back.A part spreads out light at LGP 7 anterior diffusion barriers 3 through bedding through the light of LGP 7 refractions with through the light that reflectance coating 5 reflects together uniformly through transparent panel 2 and the reflective membrane 1 that has road sign.Front vehicles ejaculation light also can reflect back through the light that reflective membrane 1 will penetrate in addition.
the foregoing description certainly only are explanation technical conceive of the present invention and characteristics, and its purpose is to let the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All modifications that the spirit of main technical schemes is done according to the present invention all should be encompassed within protection scope of the present invention.
Claims (4)
1. luminous road sign of LED; Comprise LGP (7); One side of said LGP (7) is provided with transparent panel (2), posts the reflective membrane (1) that has road sign on the said transparent panel (2), and it is characterized in that: said LGP (7) has been embedded in led light source (4).
2. the luminous road sign of LED according to claim 1 is characterized in that: the opposite side of said LGP (7) is provided with aluminium sheet (6).
