Mirror has three reflectings surface.Prism of corner cube（Reflex Reflector）It is a kind of inner full-reflection rib according to the manufacture of critical angle principle
Mirror, it is not influenceed by incident angle size, and incident light is efficiently reflected back by former direction.Retro-reflection delineator is used
When, three reflectings surface that the hexagonal cone prism of the reflected layer of incident ray has are all-trans and are incident upon photic zone, and photic zone is by reflecting layer
The light for shooting out that is all-trans reflects the profile of display road, unglazed luminance loss；The retro-reflection delineator reflecting brightness
Higher and reflected light is uniform, and the display clear security of road profile is preferable.
Preferably, three reflectings surface of described hexagonal cone prism are 35.296 degree with the angle a of reflection axis.Make
It is more preferable that light forms total reflection effect in prism of corner cube.
Preferably, described reflecting layer includes：Upper hexagonal cone prism group and lower hexagonal cone prism group；Upper hexagonal cone prism
Group hexagonal cone prism reflecting surface reflection direction to the left, the reflection of the reflecting surface of the hexagonal cone prism of lower hexagonal cone prism group
Direction is to the right.So that the reflectance lightness even intensity of two sides of left and right is consistent.
Preferably, described photic zone is provided with several directing optical lens groups.Directing optical lens group presses light
Set angle refracts to assigned direction, beneficial to seeing road profile clearly.
Preferably, described directing optical lens group has two that the directing optical lens being arranged above and below by five are constituted
It is individual；First directing optical lens group is located at photic zone top；Second directing optical lens group is located at photic zone bottom；Orientation
Optical lens includes two blocks of oblique reflection plates of high-end connection；Oblique reflection plate is 0.6 degree with euphotic angle.Beneficial to reflection light
Converge, see road profile clearly apparent.
Compared with prior art, the beneficial effects of the invention are as follows：The retro-reflection delineator reflecting brightness is higher and reflects
Light is uniform, and preferably, three reflectings surface and the angle a of reflection axis of hexagonal cone prism are the clear security of display road profile
35.296 degree.Make light that total reflection effect is formed in prism of corner cube more preferable.The hexagonal cone prism of upper hexagonal cone prism group it is anti-
Penetrate the reflection direction in face to the left, the reflection direction of the reflecting surface of the hexagonal cone prism of lower hexagonal cone prism group is to the right so that left and right
The reflectance lightness even intensity of two sides is consistent.Light is refracted to assigned direction by directing optical lens group by set angle, profit
In seeing road profile clearly.Oblique reflection plate is 0.6 degree with euphotic angle, is converged beneficial to reflection light, sees road profile clearly more
Clearly.
