Abstract
The utility model discloses a luminous road nail composed of a base, a photoluminescence screen and a biconvex spherical mirror, wherein the biconvex spherical mirror is a transparent geometrical body which has a surface shape that the two ends are in a sphere shape and the intermediate section is in a flat surface shape. The biconvex spherical mirror is embedded in the base, one end of the sphere is exposed outside the base, and the other end clings to the photoluminescence screen at the back of the sphere in the base. The utility model has advantages of small size and good luminous effects and solves the deficiencies that the prior art is greatly influenced by external environment and the lifetime is short.
Description
The utility model relates to a kind of Luminous road nail as the road safety sign.
At present, improve the speed of a motor vehicle along with the high-quality road of China's high standard constantly appears as, reduce cost of transportation, increase the benefit and created condition.Be that the safety of night running has proposed more and more higher requirement especially to the safety how support vehicles travel simultaneously.Therefore the quality of the Luminous road nail quality that identifies as driving a vehicle will directly have influence on the safety of driving at night.Yet existing traffic stud itself is not a luminous product, and it utilizes the solid of the suitable light reflection that plastics make or directly apply fluorescent coating and makes.Its shortcoming is not withstand voltage, and is easily aging, cracky, and easy laying dust, the life-span is short; And it depends on extraneous light and luminous, causes a traffic accident in case very easily make the not luminous or bright deepening of traffic stud when meeting at night the deepening of car light light, and this traffic stud also exists the defective of luminous blind spot simultaneously.
The purpose of this utility model just is to provide a kind of Luminous road nail little, that the life-span is long, illumination effect is good that is affected by the external environment.
The purpose of this utility model is achieved in that it is made up of pedestal, luminescence generated by light screen, biconvex spherical mirror, wherein the biconvex spherical mirror is that surface configuration is to be the transparent solid on plane in the middle part of two ends are sphere, the biconvex spherical mirror is embedded in the pedestal, have an end sphere to be exposed to outside the pedestal, the luminescence generated by light screen is close in the back of the sphere of the biconvex spherical mirror other end in pedestal.Principle of the present utility model is such: extraneous light almost is that the form with directional light incides the biconvex spherical mirror, the spherical outside surface planoconvex lens effect of biconvex spherical mirror is ambient light line focus and exciting light photoluminescence screen, and the light that the luminescence generated by light screen sends just can form the soft big firing angle light source that becomes clear after the flat diffuse reflective at the Internal Spherical Surface of biconvex spherical mirror, middle part.Adopt the biconvex spherical mirror can shorten light path, reduce the volume of pedestal.
For obvious, the luminous visual field of light source is broadened, can make that facial planes forms a line in contact in the plural biconvex spherical mirror in pedestal.Light path between the biconvex spherical mirror is linked up, and the light that each luminescence generated by light screen sends can fully scatter in another biconvex spherical mirror that links to each other, and almost just there is not luminous blind spot in whole traffic stud.In addition for the light that luminescence generated by light screen is sent reaches better dispersion effect, the focal distance f of the spherical outside surface of biconvex spherical mirror '=-6---10mm, the rear cut-off distance of Internal Spherical Surface is 1 '
f=-2.5---3.5mm.
The utility model with prior art relatively, because it is not to utilize principle of reflection luminous, can adopt metal to make pedestal, glass is made the biconvex spherical mirror, therefore its weatherability, withstand voltage anti-collision performance improve greatly, prolonged application life, adopt luminescence generated by light screen active illuminating in addition, it is little to be affected by the external environment, not fragile, light source is soft conspicuous, add designed light channel structure and make compact overall structure, the light source visual field is big, does not have luminous blind spot, so the utility model can provide reliable safety sign for driving at night, guarantees traffic safety.
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the utility model structural representation.
Wherein: 1, pedestal; 2, luminescence generated by light screen; 3, biconvex spherical mirror; 4, screwed hole.
Pedestal 1 is the aluminum trapezium structure, and screwed hole 4 runs through bottom surface, by screwed hole 4 usefulness bolts pedestal 1 is fixed on the road foundation.Fixing five groups of luminescence units forming by luminescence generated by light screen 2 and biconvex spherical mirror 3 on the inclined-plane of pedestal 1.Every group of luminescence unit sealing is installed in the pedestal 1, and the two ends that biconvex spherical mirror 3 is made for glass are sphere 5,6, and the middle part is the transparent body of cuboid 7.Spherical outside surface 5 exposes pedestal 1 surface, its focal distance f '=-8.38mm, imbed Internal Spherical Surface 6 in the pedestal 1 rear cut-off distance be l '
f=-3.0mm.To shine on the biconvex spherical mirror behind the optically focused exciting light photoluminescence screen luminous when external light source, and this light returns the Internal Spherical Surface 6 of footpath biconvex spherical mirror 3 again and links up into irreflexive soft bright road through light path and know sign.
