Smooth surface is connected to the both sides of bottom surface, and the remote wall reflecting surface is light can be reflexed to transition face or nearly wall exiting surface complete
Reflecting surface, the optical axis of lens passes through incidence surface and transition face.
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.
As the further improvement of such scheme, the intersection of the remote wall reflecting surface and any longitudinal section of lens is parabolic
Line, parabolical slope is gradually reduced along the direction close to transition face.
As the further improvement of such scheme, the intersection of the transition face and any longitudinal section of lens is free curve,
The slope of free curve becomes larger along the direction close to remote wall reflective surface.
As the further improvement of such scheme, the nearly wall exiting surface is any point and lens on class sphere, class sphere
Direction of the line of photocentre parallel to the light that this point is passed through in lens.
It is used 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, which is stated, with remote incidence surface.
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 tilted, and the circular cone outline straight line of the remote incidence surface is tilted to the optical axis direction close to lens.
The beneficial effects of the utility model：The utility model, can will be remote by the remote wall reflecting surface that is provided with top surface
Light from metope direction reflexes to transition face and nearly wall exiting surface, and then more light are radiated on required wall, significantly
Improve the efficiency of light energy utilization.
