Abstract
The utility model relates to a bulged light reflecting mark on a road surface, which is composed of a base and a light reflecting device, wherein the base has a thick middle and a thin edge, the light reflecting device is inlaid on an inclined surface, the front surface of the light reflecting device and the bottom surface of the base form a sharp angle of 15 DEG to 60 DEG, the back surface of the light reflecting device is provided with a retroreflecting system composed of a plurality of cubic angle type backward reflector elements, and the surfaces of the reflector elements are provided with reflecting materials and filling materials. Because of the special structure, the utility model has the advantages of good light reflecting effect, high impact resistance, long service life and easy installation on a road surface.
Description
The utility model relates to a kind of reflecting sign, particularly road surface projection reflecting sign.
Road surface projection reflecting sign, many employings apply the method for reflectorized material or sintering stained glass ball and reach reflecting effect, and its reflecting effect is not ideal enough on the road surface, and application life is shorter.
The purpose of this utility model provides the road surface projection reflecting sign that a kind of geometry that utilizes reflex reflector reaches good reflecting effect.
Pavement reflecting sign of the present utility model is made of pedestal and reflex reflector, webbing is thin in the pedestal, reflex reflector is embedded on the inclined plane, the acute angle that the front of reflex reflector is become with base bottom surface is not more than 90 °, the back side has a plurality of cubes of angie type retroeflector elements to constitute the retro-reflection system, and the reflector element surface also has one deck reflecting material.Between reflecting material and the pedestal packing material can also be arranged, it has viscosity and elasticity, to increase the impact resistant capability of reflecting sign.
Each reflector element in the retro-reflection system has three surfaces, orthogonal and intersect on away from a common point in reflex reflector front and form cube corner, one of them surface is a square, two surfaces are onesize rectangle in addition, the length of side parallel with facing of rectangle equates with the square length of side, the normal in the axis of cube corner and reflex reflector front acutangulates, and parallel with the refracted ray that enters reflex reflector.
The size at the angle that axis is become with front face normal will is decided by the ratio of two length of sides of rectangular surfaces in the trihedral, the refractive index that axis must be parallel with refracted ray, ratios then two length of sides are decided by reflex reflector.
The acute angle that the front of reflex reflector is become with base bottom surface is better with 15～60 °, makes the outstanding road surface of sign, to remain on the luminous effect of duration of work pavement marker abundance.Can clean the front of road sign when simultaneously, oncoming vehicle runs over road sign.
Reflecting material on the reflex reflector can adopt metallic reflective material such as aluminium, nickel, chromium etc.
The installation of reflecting sign on the road surface, available viscose glue such as modified epoxy will indicate that base bottom surface is fixed on the road surface and get final product.The light that the vehicle that comes head-on is launched incides the front of reflex reflector with the direction of general level, and after the refraction and reflection of incident light by reflex reflector, again probably being parallel to the incident direction of light light that turns back, so the driver can clearly see pavement marker.
Pavement reflecting sign of the present utility model, owing to have the retro-reflection system that cube angie type retroeflector element constitutes, and sign projection road surface, make incident light to reflect as much as possible, and reverberation is substantially parallel with incident light, thereby makes that the reflecting effect of sign is excellent, when the driving at night of road surface, it is very clear to indicate, traffic safety is played a part good; The front and the road surface of reflex reflector acutangulate, and can keep good daylighting effect on the one hand, also can strengthen the impact resistant capability of sign on the other hand, and the installation of sign on the road surface is simple, only need base bottom surface be bonded on the road surface with viscose glue to get final product.
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of pavement reflecting sign;
Fig. 2 is the border structural representation for retro-reflection;
Fig. 3 is the A-A sectional view of Fig. 2.
Pavement reflecting sign concrete structure such as Fig. 1 of present embodiment, the cross section of pedestal (1) is an approximate trapezoid, the top is the garden arc, it is 30 ° that inclined-plane and bottom surface acutangulate, chimb is arranged around the inclined-plane, the light-permeable sheet reflex reflector of being made by the synthetic resin body (2) is embedded on two inclined-planes of pedestal, and the front of reflex reflector is parallel to the pedestal inclined-plane and is lower than the chimb on inclined-plane slightly.The back side of reflex reflector has a plurality of cubes of angie type retroeflector elements to constitute retro-reflection system (2a), the structure of reflector element as shown in Figures 2 and 3, be a cube angie type trihedral, three mutually perpendicular faces intersect at away from the reflex reflector front a bit form cube corner, wherein
Be square
With
Be rectangle, length of side BE=EF=FG=GB=DC=CH, DE=BC=GH.The axis BN of cube corner and the front face normal will MN of reflex reflector acutangulate.There is layer of metal reflecting material aluminium (2b) on the surface of reflector element, and tool viscosity and flexible packing material (2c) are arranged between reflecting material and pedestal inclined-plane.When light incides the reflex reflector front with the direction that is parallel to ground, if refractive index 1.5, the angle of refraction is less than angle of incidence, refract light shines the retro-reflection system with the direction that is parallel to trihedral cube corner axis, through reflection and positive refraction again, light turns back to light source with the direction parallel with incident ray.
