Abstract

The utility model relates to a light-reflecting sign which is composed of a basal plate and a light-reflecting device, wherein, the facade of the light-reflecting device is smooth, and a plurality of cube corner type retrodirective reflector elements which form a retroreflection system are arranged on the back face of the light-reflecting sign; the surface of each of the reflector elements is also provided with a reflecting material layer. Owing to the specific geometric structure of the light-reflecting device, the sign has the advantages of good light-reflecting effect, simple installation and long service life. The light-reflecting sign can be used as a road sign which is higher than the road surface; besides, the light-reflecting sign can be installed on the rear face of a vehicle and can also be installed in areas or objects which need specially alarming.

Description

Reflecting sign

The utility model relates to a kind of reflecting sign.

Reflecting sign adopts on substrate the method that applies reflectorized material to reach reflecting effect more, because reflectorized material has fading or with the passing of time coming off in various degree, thereby serviceable life is not long, and reflecting effect is also not ideal enough.

The purpose of this utility model provides a kind of reflecting sign that utilizes particular geometries to reach good reflecting effect.

Reflecting sign of the present utility model is made of substrate and reflex reflector, reflex reflector is a sheet light-permeable resinite, it is positive level and smooth, the back side has a plurality of cubes of angie type retroeflector elements to constitute the retro-reflection system, the reflector element surface can also apply one deck reflecting material, reflecting material can adopt metallic reflective material such as aluminium, nickel, chromium etc., to strengthen its reflective function.

Each reflector element in the retro-reflection system have three orthogonal and intersect the surface that forms cube corner on away from a common point in reflex reflector front, one of them surface is a square, two surfaces are onesize rectangle in addition, the length of side parallel with square of rectangle equates that with the foursquare length of side axis of cube corner is parallel with the refracted ray that enters resinite.

Because the cube corner axis is parallel with refracted ray, make irradiate light behind reflecting sign, the reflection through refraction and retro-reflection system, again through reflecting, light is with the direction parallel with the incident light light source that turns back, so the reflecting effect of reflecting sign is excellent.The direction of cube corner axis is decided by the ratio of two length of sides of rectangle in the trihedral, and because axis must be parallel with refracted ray, and the direction of refracted ray is relevant with the size and the refractive index of incident angle, after reflecting sign installs, its incident angle can be regarded as necessarily, therefore, the ratio of rectangle two length of sides is decided by refractive index.

Reflective marker can be made different shape as circular, square, triangle etc., and central authorities can establish a mounting hole, are convenient to be screwed, and also available viscose glue directly is bonded at substrate bottom surface on the object; This reflecting sign has extensive applicability, as is contained in the roadside as exceeding the operation sign on road surface, or is installed in vehicle back such as bicycle, motorcycle, automobile or is installed on the zone or object that needs special caution; The front of reflecting sign is perpendicular to the ground substantially; Be mapped on the reflecting sign as illumination, the retro-reflection system of reflex reflector makes light reflect as much as possible, and reflection ray is basic parallel with incident ray, adds the effect of reflecting material, and sign seems very clear, so its reflecting effect is good; In addition, the light-transmissive resin body of reflex reflector can be made shades of colour on demand, as redness, yellow etc., makes sign more pleasing.

Below in conjunction with specific embodiment and accompanying drawing the utility model is further described:

Fig. 1 is the structural representation of reflecting sign;

Fig. 2 is the structural representation of retro-reflection system,

Fig. 3 is the A-A cut-open view of Fig. 2.

The reflecting sign of present embodiment is circular, there is a mounting hole in central authorities, the edge of reflex reflector (2) and substrate (1) are bonding, concrete structure is referring to Fig. 1, reflex reflector is the red synthetic resin body of sheet light-permeable, positive (2a) is level and smooth, the back side has a plurality of cubes of angie type retroeflector elements to constitute retro-reflection system (2b), the reflector element surface-coated has layer of metal reflecting material aluminium (2c), the structure of retro-reflection system as shown in Figures 2 and 3, each reflector element has three surfaces, and is orthogonal and intersect on away from a common point of positive (2a) and form cube corner, be BEFG BCDE BCHG, BEFG is a square, and BCDE and BCHG are rectangle, length of side BE=EF=FG=GB=DC=CH, DE=BC=GH, the installation of reflecting sign can utilize the mounting hole of central authorities to be fixed on the object, or will indicate that with viscose glue substrate bottom surface directly is bonded on the object, the reflecting sign of present embodiment is applicable to the roadside as the sign that exceeds the road surface, and sign is positive vertical with the road surface.
