Gradually replaced by LED wall wash lamp with the wall lamp of current other light sources.
Traditional wall lamp, bridge railing lamp, billboard irradiation distance are too short, and light utilization is low, for example luminous flux of light source
100lm, by lens outgoing 90lm, is actually irradiated to and there was only 40~50lm on shadow surface, therefore efficiency only has 40%~50%.
The content of the invention
In order to solve the above problems, it is an object of the invention to provide a kind of LED wall wash lamp lens, it is possible to increase luminous energy profit
With rate.
The technical solution adopted in the present invention is：A kind of LED wall wash lamp lens, including bottom surface and top surface, on the bottom surface
Groove is provided with, the wall of the groove is incidence surface, and the top surface includes being remote wall reflecting surface, nearly wall exiting surface, the mistake on convex surface
Face is crossed, the remote wall reflecting surface, transition face, nearly wall exiting surface are in smoothing junction successively, the remote wall reflecting surface and nearly wall exiting surface
The both sides of bottom surface are connected to, the remote wall reflecting surface is the total reflection that light can be reflexed to transition face or nearly wall exiting surface
Face, the optical axis of lens passes through incidence surface and transition face.
Used as the further improvement of such scheme, the lens are longitudinally asymmetric structure, and the optical axis of lens is located at lens pair
On title face.
Used as the further improvement of such scheme, the remote wall reflecting surface is parabolic with the intersection of any longitudinal section of lens
Line, parabolical slope edge is gradually reduced near the direction of transition face.
Used as the further improvement of such scheme, the transition face is free curve with the intersection of any longitudinal section of lens,
The slope of free curve becomes larger along the direction near remote wall reflective surface.
Used as the further improvement of such scheme, the nearly wall exiting surface is class sphere, any point and lens on class sphere
Direction of the line of photocentre parallel to the light that this point is passed through in lens.
As the further improvement of such scheme, it is characterised in that：The incidence surface include respectively with nearly wall exiting surface, mistake
Face, the corresponding nearly incidence surface of remote wall reflecting surface, transition incidence surface, remote incidence surface are crossed, the nearly incidence surface is plane or sphere, institute
It is taper surface that transition incidence surface is stated with remote incidence surface.
Used as the further improvement of such scheme, the circular cone outline straight line of the transition incidence surface is to the light away from lens
Direction of principal axis is inclined, and the circular cone outline straight line of the remote incidence surface is inclined to the optical axis direction near lens.
Beneficial effects of the present invention：The present invention can will be far from metope side by the remote wall reflecting surface being provided with top surface
To light reflex to transition face and nearly wall exiting surface, and then cause that more light are radiated on required wall, substantially increase light
Can utilization rate.

Specific embodiment
LED wall wash lamp lens as shown in Figure 1-2, including bottom surface and top surface 1, the bottom surface is provided with groove, described recessed
The wall of groove is incidence surface, and the top surface 1 includes being remote wall reflecting surface 11, nearly wall exiting surface 12, the transition face 13 on convex surface, described
Remote wall reflecting surface 11, transition face 13, nearly wall exiting surface 12 are in smoothing junction successively, the remote wall reflecting surface 11 and nearly wall exiting surface 12
The both sides of bottom surface are connected to, the remote wall reflecting surface 11 is that light can be reflexed into transition face 13 or nearly wall exiting surface 12
Fully reflecting surface, the optical axis of lens passes through incidence surface and transition face 13.By the remote wall reflecting surface 11 being provided with top surface 1, can
The light that will be far from metope direction reflexes to transition face 13 and nearly wall exiting surface 12, and then causes that more light are radiated at required wall
On, substantially increase the efficiency of light energy utilization.
Preferably, the lens are longitudinally asymmetric structure, light is uniformly irradiated to the metope of lens both sides, thoroughly
The optical axis of mirror is located on the lens plane of symmetry.
Preferably, the remote wall reflecting surface 11 and the intersection of any longitudinal section of lens are parabola, parabolical slope edge
Direction near transition face 13 is gradually reduced, and parabolical slope changes with the angle of incident light so that light is more thrown
To wall top.
Preferably, the transition face 13 and the intersection of any longitudinal section of lens are free curve, the slope edge of free curve
Direction near remote wall reflective surface becomes larger so that invest metope from the light of the outgoing of transition face 13.
