In addition, unless otherwise defined, the technology of all technical and scientific terms used herein and the art The normally understood meaning of personnel is identical.Term used in the description is intended merely to description specific embodiment herein, without It is to limit the utility model.Term " and or " used herein includes appointing for one or more relevant listed items The combination of meaning.

Referring to figs. 1 to Fig. 4, a kind of stereoscopic schematic diagram of light-distribution lens, the section view of bottom view and the direction A-A, B-B are shown Figure.

Light-distribution lens include bottom 1 and lug boss 2.Bottom 1 is cylinder, and bottom profile includes two sections of raised circular arcs and is located at Two interior concave arcs between the protrusion circular arc, above-mentioned four circular arcs are smoothly connected, and form a closed figure, the bottom Face is axially symmetric structure.Using the center of bottom surface as origin O；The shortest point of distance and original between bottom surface outer profile sideline and origin O Direction determined by point O is X-axis；The longest point of distance and direction determined by origin O between bottom surface outer profile sideline and origin O For Y-axis；The direction of vertical bottom face is Z axis；Establish O-XYZ coordinate system.Bottom 1 is symmetrical about XOZ plane, and bottom 1 is also about YOZ Plane is symmetrical.

The top of bottom 1 is equipped with lug boss 2, and lug boss 2 is including the first lug boss 21, the second lug boss 22 and is located at the two Between transition part 23；Wherein the first lug boss 21 is identical with 22 shape of the second lug boss and about XOZ plane and YOZ plane is in Axial symmetry.The outer wall of first lug boss 21 (or second lug boss 22) is smooth free form surface, the side of its underpart and bottom 1 Smooth transition.In addition, the first lug boss 21 and/or the second lug boss 22 are also possible to spherical surface.

Transition part 23 is set to the top of bottom 1, and between the first lug boss 21 and the second lug boss 22.Transition part 23 Outer surface and the outer wall of the first lug boss 21, the outer wall of the second lug boss 22 and bottom 1 smooth-sided it is excessive.Preferably, Transition part 23 also about XOZ plane and YOZ plane axisymmetricly.

As shown in Figures 2 to 5, one is additionally provided on the bottom surface of bottom 1 for accommodating the groove 3 of LED light source 4.It is described Groove 3 includes the front side wall 31 perpendicular to bottom surface, rear wall 32 and the bottom wall 33 for connecting front side wall and rear wall.

Bottom wall 33 is free form surface, and symmetrical about XOZ plane.The plane of bottom wall 33 and YOZ plane, parallel YOZ plane The curve of intersection is elliptic arc.Bottom wall is symmetrical about YOZ plane, is ellipse with XOZ plane or the intersection for being parallel to XOZ plane Arc.In addition, the curve that bottom wall intersects with the plane of parallel YOZ plane (or XOZ plane) can also be semi arch, minor arc or excellent Arc；It does not limit one by one herein.

Referring to Fig. 5, the path that light passes through the light-distribution lens is shown.LED light source 4 is located in groove 3, it is preferred that lamp The center of pearl is located at origin O.Light-distribution lens select transparent material, and when LED light source 4 shines, light passes through bottom wall 33, are refracted into In light-distribution lens；It is refracted into air using the outer wall of the first lug boss 21 (or second lug boss 22), is irradiated to ground On.

For LED light source in the direction of direct projection, light intensity is stronger, and the direction of oblique fire, light intensity is weaker, whole that intermediate bright, surrounding is presented Dark situation.First lug boss and the second lug boss can be such that the light close to centre reflects toward the two sides far from XOZ plane, make original This is mobile toward periphery relative to intermediate light, to improve the light intensity at edge.In this way, the light intensity of lens two side areas can also expire Sufficient use demand.

Referring to Fig. 6, a kind of light distribution panel is shown.The light distribution panel includes that substrate 51 and the multiple light distributions being set on substrate are saturating Mirror 52.

Substrate 51 is rectangle, and multiple light-distribution lens 52 are arranged in arrays along the sideline of substrate 51.It is carried on the back in substrate 51 Side from lug boss and the white space for being not provided with groove, are handled by frosted.The light distribution panel is used to have multiple LED lights On the lamp lamps and lanterns in source, LED light source is located on the light distribution panel in the groove at light-distribution lens back.

The utility model also provides a kind of lamps and lanterns, the LED light source including above-mentioned light distribution panel and in light distribution panel.

The lamps and lanterns can be used as the street lamp being located on greenbelt, thereon the YOZ plane of each light-distribution lens and road driving side To vertical.Relatively traditional street lamp, the light which launches, the light intensity immediately below the lamps and lanterns on road is accordingly lower, and two Light intensity on the road of side is stronger, to meet the use demand of road at night time.And it because being without the use of two lamp bodies, is promoted The service efficiency of luminous energy.

In addition, the shape of light distribution panel can also be round, polygon or other shapes, shape on lamp body with its phase The structure of cooperation is identical；Transition part on light-distribution lens can also not have；Light source in groove arranged at the bottom can also To be other illuminating sources in addition to LED light source；Here, not limiting one by one.

It is illustrating for progress to be implemented to the preferable of the utility model, but the invention is not limited to the reality above Example is applied, those skilled in the art can also make various equivalent variations without departing from the spirit of the present invention Or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
