Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It should be noted that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 2 and 3, a reflector 10 is provided in a first embodiment of the present disclosure, for reflecting a light beam incident on the reflector 10 and then emitting the light beam at a specific angle, so that an included angle between the incident light on the reflector 10 and the emitted light reflected by the reflector 10 is n (not shown). The reflector 10 includes a first reflection surface OAB, a second reflection surface OBC, and a third reflection surface OAC.

The included angle between any two of the first reflecting surface OAB, the second reflecting surface OBC and the third reflecting surface OAC is a preset angle m, and the first reflecting surface OAB, the second reflecting surface OBC and the third reflecting surface OAC jointly form a cone-angle prism.

In the present embodiment, the first reflecting surface OAB, the second reflecting surface OBC, and the third reflecting surface OAC collectively form a triangular pyramid, three surfaces of which are formed by the above reflecting surfaces, and the other surface of which is vacant and faces the incident light direction.

The predetermined angle m between the first reflection surface OAB, the second reflection surface OBC, and the third reflection surface OAC is determined by an included angle n between the incident light and the emergent light, specifically (90+ n/2) degree or (90-n/2) degree, and 0< n <90 degrees, for example: n may be 20 degrees.

It can be understood that, after incident light enters the reflector 10, the incident light can be emitted after being reflected by at least two reflecting surfaces, and since the included angle between any two reflecting surfaces is (90+ n/2) degrees or (90-n/2) degrees, the included angle between the incident light and the emergent light is n degrees.

In the first embodiment, the angle between the incident light and the normal of the third reflection surface OAC is x, and the angle between the emergent light and the normal of the second reflection surface OBC is y. Therefore, the angle between the light reflected by the third reflection surface OAC and the normal of the third reflection surface OAC is also x, the angle between the light reflected by the second reflection surface OBC and the normal of the second reflection surface OBC is also x ', the angle between the light reflected by the second reflection surface OBC and the normal of the second reflection surface OBC is also y, and the angle between the light reflected by the second reflection surface OBC is y'.

The sum of the inner angles according to the triangle is 180 degrees, and the predetermined angle m between the second reflecting surface OBC and the third reflecting surface OAC is (90-n/2) degrees, so x '+ y' ═ 180- (90-n/2) ═ 90+ n/2 degrees. Further, since x and x 'are complementary and y' are complementary, if x + y is 180- (90+ n/2) — (90-n/2) degrees, 2x +2y is estimated as (180-n) degrees. It can be understood that a triangle can be formed by incident light, reflected light between two reflecting surfaces and three emergent light, and the sum of the internal angles of the triangle is 180 degrees, so that 2x +2y + n is 180 degrees, and the degree of the included angle between the incident light and the emergent light is n.

The reflector 10 provided by the application realizes that the emergent light is formed at a required angle after the incident light is controlled to be reflected by arranging the three reflecting surfaces and setting the included angle between the reflecting surfaces by the required included angle between the incident light and the emergent light. Compare in traditional retro-reflector, when this application was applied to the traffic safety field, can return the light of penetrating along certain direction for traffic field equipment such as traffic indicator can exert the warning effect better.

Further, in this embodiment, as shown in fig. 3, the ≧ AOB shown in the figure is the included angle between the second reflection surface OBC and the third reflection surface OAC, the included angle degree is (90-n/2) degrees, that is, < AOB is an acute angle.

Specifically, an acute angle is used as an included angle between different reflecting surfaces, so that emergent light formed after incident light is reflected by the reflecting surfaces on the two surfaces can incline to a position close to the incident light by n degrees, and the included angle between the incident light and the emergent light is n degrees.

It can be understood that, when the angle n between the required incident light and the emergent light is 0 degree, that is, the incident light is parallel to the emergent light, the included angle between any two of the first reflecting surface OAB, the second reflecting surface OBC, and the third reflecting surface OAC is 90 degrees, that is, the first reflecting surface OAB, the second reflecting surface OBC, and the third reflecting surface OAC are perpendicular to each other.

Further, in this embodiment, the first reflecting surface OAB, the second reflecting surface OBC, and the third reflecting surface OAC are all triangular and isosceles triangles, and further form a triangular pyramid.

Referring to fig. 4, a second embodiment of the present application provides a reflector 10, which is similar to the reflector 10 of the first embodiment, and the difference between the second embodiment and the first embodiment is that ≧ AOB shown in the figure is an included angle between the second reflection surface OBC and the third reflection surface OAC, and the degree of the included angle is (90+ n/2), that is, < AOB is an obtuse angle.

It can be understood that the obtuse angle is used as an included angle between different reflecting surfaces, so that emergent light formed after incident light is reflected by the reflecting surfaces on the two surfaces can incline towards a position far away from the incident light by n degrees, and the included angle between the incident light and the emergent light is also realized to be n degrees. The n degree deviation angle of the second embodiment is opposite to that of the first embodiment.

It will be appreciated that, in the actual application of the reflector 10, the angle between the reflecting surfaces may be selected to be a suitable angle, i.e. the angle may be (90+ n/2) or (90-n/2) according to the required reflection angle.

Referring to fig. 2 and fig. 5, a reflection apparatus 100 including a plurality of reflectors 10 according to a third embodiment of the present invention is provided.

It can be understood that the plurality of reflectors 10 are arranged in an array and closely arranged, so that when a large light beam is incident, all light rays can be reflected back according to a preset angle.

In the present embodiment, the reflector 10 has a substantially triangular pyramid shape, and the plurality of reflectors 10 are arranged in series.

It will be appreciated that a plurality of reflectors 10 may be arranged in a plane or a curved surface to achieve applications in different environments. For example: the reflection apparatus 100 is disposed on a flat road sign at the side of a road or on a soft cloth of a traffic police uniform.

It will be appreciated that fig. 5 shows only one arrangement of reflectors 10 in the reflector device 100, and that in practice, depending on the environment in which the reflector device 100 is used, suitable arrangements may be used.

Further, referring to fig. 6, a reflection apparatus 100 is provided in a fourth embodiment of the present application, which is similar to the reflection apparatus 100 of the third embodiment, and the difference between the fourth embodiment and the third embodiment is that the structure of the reflector 10 of the fourth embodiment is different from that of the reflector 10 of the third embodiment.

Specifically, in the present embodiment, the first reflective surface, the second reflective surface, and the third reflective surface of the reflector 10 are all quadrilateral, and the first reflective surface, the second reflective surface, and the third reflective surface together form three adjacent surfaces in a hexahedron, and the vertex of the three surfaces is a cone angle.

It is understood that, compared to the first to third embodiments, the shapes of the first, second, and third reflective surfaces in this embodiment are changed from triangular to quadrangular, but the pyramidal prisms are still composed of three surfaces. The quadrilateral has a larger reflecting surface when reflecting, and the corresponding occupied space is larger.

Further, referring to fig. 7, a fifth embodiment of the present application provides a reflection apparatus 100, which is similar to the reflection apparatus 100 of the third embodiment and the fourth embodiment, and the difference of the fifth embodiment is that the structure of the reflector 10 is different from the reflector 10 of the third embodiment and the fourth embodiment.

Specifically, in the present embodiment, the first reflecting surface, the second reflecting surface, and the third reflecting surface of the reflector 10 are all pentagons. That is, the first reflection surface, the second reflection surface and the third reflection surface are approximately three adjacent surfaces in a dodecahedron, and the vertexes of the three surfaces are cone angles.

It is understood that, compared to the fourth embodiment, the shapes of the first, second and third reflective surfaces in this embodiment are changed from quadrilateral to pentagonal, but the three surfaces still form a cone prism. When the reflectors 10 in the pentagon shape are arranged in a concentrated manner, the arrangement is denser, the occupied space is smaller, and meanwhile, a better reflection effect is also considered.

It can be understood that, in some embodiments, the shapes of the first reflective surface, the second reflective surface and the third reflective surface may be regular pentagons, so as to achieve uniform and regular arrangement of the plurality of reflective surfaces.

It is understood that in other embodiments of the present application, the shapes of the first, second and third reflective surfaces are not limited to the triangular, quadrilateral and pentagonal shapes in the above embodiments, and other shapes may be used as long as the three reflective surfaces are combined to form a cone-angle prism.

Referring to fig. 8, the present application also provides a traffic indicator 200 having the reflection device 100 and an automobile 300 having the reflection device 100.

The traffic indicator 200 includes a body 210 and a reflection device 100, and the reflection device 100 is mounted on the body 210 for reflecting light.

Specifically, the traffic indicator 200 is a traffic light, and when a driver drives the automobile 300 forward, light emitted from a lamp of the automobile 300 can be emitted at a specific angle after being reflected by the reflection device 100, so as to be emitted to a sight area of the driver, so that the driver can find and judge the indication information of the traffic light more easily.

In the present embodiment, the reflection angle n of the reflector 10 in the traffic indicator 200 is 20 degrees, which corresponds to the angle between the lights of the automobile 300 and the position of the driver relative to the traffic indicator 200.

It is understood that the traffic indicator 200 may also be a road sign, roadside reflector, or fence, among other traffic components with indicating functions.

The car 300 includes a car body 310 and the reflecting device 100, and the reflecting device 100 is installed on the outer surface of the car body 310 to reflect light.

In the present embodiment, the reflection device 100 is installed at a tail lamp of the vehicle body 310 for reminding a following vehicle of paying attention to the distance. Specifically, light emitted by a lamp of a vehicle driving from the rear can be emitted at a specific angle after being reflected by the reflection device 100, so that the light is emitted to a sight area of a driver driving from the rear, the driver can easily find a vehicle ahead, and the safety protection effect is achieved.

It is understood that the reflective device 100 can be mounted in other positions on the vehicle body 310. Including but not limited to exterior surfaces such as the front of the body 310, mirrors, and roof.

The reflector 10 and the reflection device 100 with the reflector 10 provided by the application realize that the emergent light is formed at a required angle after the incident light is reflected by arranging the three reflection surfaces and setting the included angle between the reflection surfaces by the required included angle between the incident light and the emergent light. Compared with the traditional retro-reflector, when the reflector is applied to the traffic safety field, the incident light can be returned along a certain direction, so that traffic field equipment such as the traffic indicator 200 and the automobile 300 can play a better warning role, and the probability of traffic accidents is reduced.
