Abstract
The utility model discloses an LED luminous road sign which comprises a light guide panel. A transparent board is disposed on one side of the light guide panel. A reflecting film with an attached road sign is attached to the transparent board. An aluminum plate is disposed on the other side of the light guide panel. An LED light source is inlaid in the light guide panel. The LED luminous road sign allows a driver to clearly see under lighting of a presenting car light, and also allows the driver to clearly see even in the absence of external light sources, and the driver can make more reasonably judgments.
Description
Technical field
The utility model designs 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 light guide plate, the front end of organic light guide plate is provided with panel, panel is provided with road signs indication film, outer periphery at described base plate, organic light guide plate, panel and road indication film is equipped with peripheral protective layer, and the inwall that faces the peripheral protective layer of organic light guide plate is provided with several led light sources.Work as opening power, LED lights and by light guide plate 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 by light guide plate 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 in the periphery of light guide plate LED is installed, for traffic indication board be have circumscribed.Because at different roads, the speed of a motor vehicle of requirement is different, the size that the sign board of so same content adopts 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 light guide plate behind the large-area sign board.
The utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of LED is provided luminous road sign.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
The luminous road sign of a kind of LED comprises a light guide plate, and a side of described light guide plate is provided with transparent panel, posts the reflective membrane that has road sign on the described transparent panel, and the opposite side of described light guide plate is provided with aluminium sheet, and described light guide plate has been embedded in led light source.
Further, be provided with diffusion barrier between described aluminium sheet and the described light guide plate.
Further, be provided with reflectance coating between described transparent panel and the described light guide plate.
Principle of work of the present utility model is as follows:
Be embedded in the led light source in the described light guide plate, send light and reflect away by light guide plate.The light of to the reflectance coating of bedding on aluminium sheet refraction being come when light reflects back.A part spreads out light by the diffusion barrier of bedding in the light guide plate front portion together uniformly by the light of light guide plate refraction with by the light that reflectance coating reflects by transparent panel and the reflective membrane that has road sign.Front vehicles ejaculation light also can reflect back by the light that reflective membrane will penetrate in addition.
The beneficial effects of the utility model are as follows:
Inlay led light source and rationally arrange led light source quantity as required at the light guide plate periphery.Because led light source is single direct light, after light guide plate, light refraction goes out light guide plate, all goes out by the light guide plate front portion in order to make light, makes the light that passes the light guide plate rear portion change direction so paste one deck reflective membrane at the light guide plate rear portion, reflects.Not single direct light in order to make light in addition, so in the light guide plate front portion one deck diffusion barrier is set, make the light by the light guide plate front portion, reflect away uniformly.Namely increased luminous flux, made light not too dazzling again.What the luminous road sign of LED of the present utility model made both can have under the car light situation and will the driver seen clearly traffic indication board; Also can under the situation that does not have external lamp source, the driver be seen clearly direction board.Be convenient to the driver and make more rational judgement.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 structural representation of the present utility model.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Figure 1, the luminous road sign of a kind of LED comprises a light guide plate 7, one side of described light guide plate 7 is provided with transparent panel 2, post the reflective membrane 1 that has road sign on the described transparent panel 2, the opposite side of described light guide plate 7 is provided with aluminium sheet 6, and described light guide plate 7 has been embedded in led light source 4.
Further, be provided with diffusion barrier 3 between described aluminium sheet 6 and the described light guide plate 7.
Further, be provided with reflectance coating 5 between described transparent panel 2 and the described light guide plate 7.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
