Abstract

The utility model relates to a reflection warning device, and particularly to a reflex reflector. The reflex reflector comprises an euphotic layer and a reflecting layer. The reflecting layer is obtained through arranging the corner cube prisms with 0.2 DEG of viewing angle. The corner cube prisms causes the included angle between the reflection ray reflected from the euphotic layer and the incident ray before entering the euphotic layer to be 0.2 DEG. The corner cube prisms with 1.5 DEG of viewing angle are distributed in the corner cube prism array. The corner cube prisms with 1.5 DEG of viewing angle causes the included angle between the reflection ray reflected from the euphotic layer and the incident ray before entering the euphotic layer to be 1.5 DEG. The included angle between twoadjacent reflection surfaces of the corner cube prism with 1.5 DEG of viewing angle is in the range of 88.15-88.75 DEG. The reflex reflector provided by the utility model has the advantages of rationally designed structure and simple machining of the mould for the reflex reflector. The pressing dent edge is not required on the surface of mould chamber. The mould is not damaged. The light intensitywhich satisfies the compulsory standard exists at each viewing angle, and the possibility that the user is impacted is reduced.

Description

Reflex Reflector
Technical field
The utility model relates to a kind of reflection alarming equipment, specifically relates to a kind of Reflex Reflector.
Background technology
The plastics Reflex Reflector mainly applies to bicycle, motorcycle, traffic safety warning marks such as the back light side lamp of automobile and highway, existing Reflex Reflector all is shaped by high-accuracy mold injection, it is that 0.2 degree and 1.5 degree (or 0.333 degree and 1.5 degree) Shi Yaoyou meet the light intensity of pressure standard by the refracted ray that Reflex Reflector reflects in viewing angle (angle of incident ray and refracted ray) that a qualified Reflex Reflector requires light. the light that existing Reflex Reflector incident ray reflects by Reflex Reflector satisfies the intensity of light reflection that viewing angle is 0.2 degree (or 0.333 a degree) scope, the technical scheme that is adopted is by the array amalgamation of pyramid rib border together, and incident ray reflects realization by triple reflection and twice refraction with small reflection angle.
Realize that as for the refracted ray that incident ray reflects by Reflex Reflector viewing angle is the intensity of light reflection requirement of 1.5 degree, the structure of existing Reflex Reflector is the fin that forms many certain angles at the photic zone of Reflex Reflector. light makes Reflex Reflector reach the reflective requirement that viewing angle is 1.5 degree by the refraction of the fin of band certain angle, traditional way is at the surface of die cavity indentation rib both at home and abroad, the photic zone of the Reflex Reflector after the injection moulding just forms fin like this, by fin to ray refraction realize viewing angle be 1.5 the degree reflective reading requirements.But it is the intensity of light reflection that 0.2 degree or 0.333 degree are gone up standard-required that the fin of product surface can reduce viewing angle, influence the outward appearance of product and harder owing to mould in the process of indentation rib simultaneously, and the drift of indentation rib is harder, hard material is more crisp, and recessed rib is smaller, thereby the easy broken mold damage of process drift of indentation rib. also have one more major defect be exactly behind Reflex Reflector photic zone formation fin, the cross section of fin is an isosceles triangle, how to put all is to be with certain orientation, Reflex Reflector when mounted, the fin installation position has strict demand, light after the refraction just can be observed in 1.5 degree angles like this, and for the user this is known nothing, even therefore on the product Reflex Reflector is installed, but because setup error causes the no-reflection effect, be very unsafe to the user like this, this is more outstanding to profile Reflex Reflector in the form of annular discs, thereby the arbitrarily angled reflective requirement that all will satisfy standard 1.5 degree viewing angles of the Reflex Reflector of present European ECE standard-required circle requirement 360 degree rotations, viewing angle is that the reflective requirements of 1.5 degree will be the requirements that is difficult to satisfy rotary test by the fin that has directivity like this.
Summary of the invention
First purpose of the present utility model is to provide a kind of Reflex Reflector, and the light that light reflects by this Reflex Reflector is that 0.2 degree and 1.5 degree have the light intensity of conformance with standard requirement and directionless restriction and safer Reflex Reflector that can arbitrarily angled installation in viewing angle.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of Reflex Reflector, comprise photic zone and reflection horizon, arrayed is pressed by the prism of corner cube of 0.2 degree viewing angle in the reflection horizon, it is 0.2 degree that this prism of corner cube makes the refracted ray that reflects from photic zone and the incident ray angle that enters before the photic zone, in above-mentioned micro-prism array, also be distributed with the prism of corner cube of 1.5 degree viewing angles, it is 1.5 degree that prism of corner cube of this 1.5 degree viewing angle makes the refracted ray that reflects from photic zone and the incident ray angle that enters before the photic zone, and the adjacent two reflecting surface angles of prism of corner cube of 1.5 degree viewing angles are the 88.15-88.75 degree.
Second purpose of the present utility model is to provide a kind of Reflex Reflector, and the light that light reflects by this Reflex Reflector is that 0.333 degree and 1.5 degree have the light intensity of conformance with standard requirement and directionless restriction and safer Reflex Reflector that can arbitrarily angled installation in viewing angle.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of Reflex Reflector, comprise photic zone and reflection horizon, arrayed is pressed by the prism of corner cube of 0.333 degree viewing angle in the reflection horizon, it is 0.333 degree that this prism of corner cube makes the refracted ray that reflects from photic zone and the incident ray angle that enters before the photic zone, in above-mentioned micro-prism array, also be distributed with the prism of corner cube of 1.5 degree viewing angles, it is 1.5 degree that prism of corner cube of this 1.5 degree viewing angle makes the refracted ray that reflects from photic zone and the incident ray angle that enters before the photic zone, and the adjacent two reflecting surface angles of prism of corner cube of 1.5 degree viewing angles are the 88.15-88.75 degree.
Reflex Reflector in above-mentioned two technical schemes generally has the prism of corner cube of 4-20 1.5 degree viewing angles, if the increase that Reflex Reflector more greatly can be suitable does not have too big restricted number as long as can satisfy standard-required.Calculate every square centimeter 1-2 if press area.
Incident ray is introduced into photic zone and reflects in above-mentioned two technical schemes, and the reflecting surface through the pyramid rib border of corresponding same viewing angle carries out triple reflection respectively again, reflects through photic zone again.
Above-mentioned two technical schemes have solved can not there be 2 different viewing angles in people all the time simultaneously in same Reflex Reflector prism of corner cube problem.
The utility model reasonable in design, the Mould Machining of Reflex Reflector is simple, not be used in cavity surface indentation rib, mould can be not impaired, the Reflex Reflector outward appearance is more beautiful, and no requirement (NR) particularly is installed, and the user can not install because of mistake and produce danger, each viewing angle all has the light intensity that meets the pressure standard, has reduced the possibility that the user is clashed into.
