Abstract

The utility model relates to a traffic sign which applies an optical membrane, which comprises a light conducting body, an optical membrane and at least one light source, wherein diffused mesh points are printed on the light conducting body, thereby after light rays of the light source are emitted, a face light source with high evenness can be produced, the optical membrane which is clung to the surface and is provided with traffic indication symbols forms a thin type traffic sign with even illumination, and the light source can adopt a luminescent diode to provide the traffic sign with the power-saving advantage.

Description

The traffic sign of applied optics diaphragm

Technical field

The utility model relates to a kind of traffic sign, relates in particular to a kind of slimming, uniformly light-emitting and energy-conservation traffic sign.

Background technology

Traffic sign is a direction board important on the road, it learns road conditions for the vehicle driver who travels on the road, for making traffic sign be found by the vehicle driver easily and watch at night, at present traffic sign change to gradually can be luminous traffic sign, to be added to the identification at night.

See also shown in Figure 1, present luminous traffic sign, its structural group becomes to utilize makes the casing 1 that the surface has traffic designated symbol 3 as the plastics of acryl, and in casing 1, put as the light-emitting component of daylight lamp 2, with traffic designated symbol 3 formations on light by daylight lamp 2 and casing 1 surface can be luminous traffic sign.

This known traffic sign that can be luminous, for ccontaining daylight lamp 2, its casing 1 necessary suitable thickness of tool, thereby it can take suitable space and have suitable weight, so when it is arranged on the road, can influence driver's sight line and get loose easily and drop and damage, and storing daylight lamp 2 in the casing 1, its luminous uniformity coefficient is not good, have zonal jump in brightness, cause the visual puzzlement of driver, then need many daylight lamp 2 is set as increasing casing 1 luminous homogeneity, and consume a large amount of electric power.

Summary of the invention

Therefore, it is a kind of slim, energy-conservation and the traffic sign of uniform luminance can be provided that fundamental purpose of the present utility model is to provide, and for being arranged on the road, saving use cost and increase vehicle driver's the visual field.

Via as can be known above, for achieving the above object, the utility model is a kind of traffic sign of applied optics diaphragm, it comprises a light guide body, a blooming piece and at least one light source, the a plurality of diffusions of printing site on this light guide body, this light source is close to this light guide body setting and emits beam and enters this light guide body, and this blooming piece is close on the surface of this light guide body, and this blooming piece is provided with a traffic designated symbol in lateral surface.

In view of the above, the utility model provides uniform surface light source by this light guide body and in conjunction with the traffic designated symbol on this blooming piece, promptly constitute one can be luminous traffic sign, it compares known, has luminous advantage such as even, frivolous, energy-conservation, it can provide preferable identification for being arranged on the road, and saves use cost and increase vehicle driver's the visual field.

Embodiment

For to feature of the present utility model, purpose and effect, more deep understanding and approval are arranged, enumerate a preferred embodiment and cooperate schematic view illustrating as back:

See also Fig. 2-1 with shown in Fig. 2-2, the utility model is the traffic sign of applied optics diaphragm, it comprises a light guide body 10, a blooming piece 20 and at least one light source 30, wherein print a plurality of diffusions site 11 on this light guide body 10, this light source 30 can be light emitting diode (LED) or cold-cathode tube (CCFL), and this light guide body 10 can be tabular or swash plate shape (as shown in Figure 4), and allow this light source 30 be arranged at the side edge of this

light guide body

10,31 enter this light guide body 10 and this light guide body 10 of this light source 30 next-door neighbours is provided with and emits beam.

Can make this light guide body 10 become the area source of high evenness after the repeatedly scattering of light 31 through this diffusion site 11 of this light source 30, this blooming piece 20 is close on the surface of this light guide body 10, and this blooming piece 20 is provided with a traffic designated symbol 21 in the surface of lateral surface, this traffic designated symbol 21 can be any symbol with special connotation,, attention curved, road name etc., and its printing or stick on this blooming piece 20 as the right side.In addition, a reflector plate 40 can be set up in the below of this light guide body 10, and this reflector plate 40 can reflect the light 31 of this light source 30, light 31 is directed to by this blooming piece 20 places penetrates.

Please consult shown in Figure 3ly again, be another embodiment of the present utility model, wherein this light guide body 10 is a tabular, and this light source 30 can be arranged at this light guide body 10 belows, and it can allow the light 31 of this light source 30 enter this light guide body 10 equally.And this blooming piece 20 can repeatedly be attached to the surface of this light guide body 10, thereby can change suitable traffic designated symbol 21, with the demand of realistic road conditions according to the actual needs of road.

As mentioned above, the utility model enters this light guide body 10 by light 31, scattering effect by diffusion site 11, allow this light guide body 10 form the area source of suitable high evenness, it can increase identification and slimming easily, and the light source 30 of collocation light emitting diode uses, and can reach energy-conservation effect, thereby its use cost is cheap and can not influence driver's sight line.
