Abstract

The utility model discloses a light-emitting diode (LED) luminescent road sign board which comprises a light guide plate. A transparent plate is arranged on one side of the light guide plate, a light reflection film with a road sign is adhered to the transparent plate, an LED light source is embedded into the light guide plate, an aluminum plate is positioned on the other side of the light guide plate, a reflection film is positioned between the aluminum plate and the light guide plate, and a diffusion film is arranged between the transparent pate and the light guide plate. The LED luminescent road sign board can be seen clearly by drivers under the situations of car lamp illumination and without external light sources.

Description

LED luminescent road sign board
Technical field
The utility model relates to a kind of road indicating signboard.
Background technology
Existing LED face luminescent road sign board, front position in the bottom is provided with organic light guide plate, the front end of organic light guide plate is provided with panel, be provided with the road signs indicating film on the panel, periphery at described base plate, organic light guide plate, panel and road indicating film is provided with peripheral protective layer, is provided with several led light sources at the inwall of the peripheral protective layer that faces organic light guide plate.Work as opening power, LED lights and by light guide plate light is spread out of.But this LED face luminescent road sign board has two serious defectives.
At first, owing to only a small amount 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, can not be too far away so that transmit distance.So 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.
Summary of the invention
The utility model purpose is: a kind of LED luminescent road sign board is provided, both can the driver was seen clearly traffic indication board having in the situation of car light irradiation; Also can in the situation that does not have external lamp source, the driver be seen clearly direction board.
The technical solution of the utility model is: a kind of LED luminescent road sign board, comprise light guide plate, and a side of described light guide plate is provided with transparent panel, posts the reflective membrane with road sign on the described transparent panel, and described light guide plate has been embedded in led light source.
Preferably, the opposite side of described light guide plate is provided with aluminium sheet.
Preferably, be provided with reflectance coating between described aluminium sheet and the described light guide plate.
Preferably, be provided with diffusion barrier between described transparent panel and the described light guide plate.
The utility model has the advantages that:
1. the utility model is embedded in led light source in the light guide plate, rather than in the periphery of light guide plate LED is installed, and has solved the limitation that traffic sign size difference is brought.
2. the utility model pastes one deck reflective membrane and makes the light change direction of passing the light guide plate rear portion at the light guide plate rear portion, reflects, and light is all gone out by the light guide plate front portion.
3. the utility model arranges one deck diffusion barrier in the light guide plate front portion, makes the light by the light guide plate front portion, reflects away uniformly, and making light is not single direct light, has both increased luminous flux, makes again light not too dazzling.
4. the utility model both can make the driver that traffic indication board is seen clearly having in the situation of car light irradiation; Also can in the situation that does not have external lamp source, the driver be seen clearly direction board.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Wherein: 1, reflective membrane; 2, transparent panel; 3, diffusion barrier; 4, led light source; 5, reflectance coating; 6, aluminium sheet; 7, light guide plate.
Embodiment
Embodiment: as shown in Figure 1, LED luminescent road sign board comprises light guide plate 7, and a side of described light guide plate 7 is provided with transparent panel 2, posts the reflective membrane 1 with road sign on the described transparent panel 2, and described light guide plate 7 has been embedded in led light source 4.
The opposite side of described light guide plate 7 is provided with aluminium sheet 6, is provided with reflectance coating 5 between described aluminium sheet 6 and the described light guide plate 7, is provided with diffusion barrier 3 between described transparent panel 2 and the described light guide plate 7.
Principle of work of the present utility model is as follows:
Be embedded in the led light source 4 in the described light guide plate 7, send light and reflect away by light guide plate 7.The light of to the reflectance coating 5 of bedding on aluminium sheet 6 refraction being come when light reflects back.Light and the light that by reflectance coating 5 reflects of a part by light guide plate 7 refraction spreads out light at the diffusion barrier 3 of light guide plate 7 front portions uniformly by bedding together by transparent panel 2 with the reflective membrane 1 of road sign.Front vehicles ejaculation light also can reflect back by the light that reflective membrane 1 will penetrate in addition.
Certainly above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All modifications of doing according to the Spirit Essence of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
