Understandable, described first cross section can also be any one plane paralleled with two dimensional surface X-Y of transversal described optical lens 30; Described second cross section also can be any one plane paralleled with two dimensional surface Z-Y of transversal described optical lens 30.
Luminescence unit 10 of the present invention can be used for street lighting, and during work, highway is irradiated via after exiting surface 311 refraction again in the inside that the light that LED source 20 sends is incident to optical lens 30 after the incidence surface 321 of optical lens 30 reflects.
Refer to Fig. 2, in the first cross section or be parallel in other plane in the first cross section, because described end face 31 and bottom surface 32 are all symmetrical about axes O Y, therefore LED source 20 send the exit path of light also symmetrical about axes O Y.Because the radius of curvature of described incidence surface 321 is successively decreased gradually along the forward of axes O 2Y2, on described exiting surface 311, the radius of curvature of each free form surface increases progressively gradually along the forward of axes O 1Y1, LED source 20 send light can be divided into two kinds of situations (light for axes O X forward):
LED source 20 send become with axes O Y shape less rising angle (as, 0 ° to X °, 0<X<90 °) light, namely, the forward light of deflection axes O Y, as light A, after described incidence surface 321 reflects above axes O X and to enter optical lens 30 inner in the direction of being partial to axes O X a little, then be incident to described exiting surface 311, after described exiting surface 311 reflects further towards axes O X forward bias from.Free form surface so through described incidence surface 321 and exiting surface 311 coordinates, the angle that the light with less rising angle that LED source 20 is sent is partial to the side of described luminescence unit 10 increases, thus make this luminescence unit 10 have the forward light strong compared with high light to offset towards axes O X, weaken forward and go out luminous intensity, be overall light homogenising, increase the lighting angle of luminescence unit 10 simultaneously.
What LED source 20 sent become with axes O Y shape larger rising angle (as, X ° to 90 °, 0<X<90 °) light, namely, the side direction light of deflection axes O X, as light B, is partial to the forward of axes O Y a little after described incidence surface 321 reflects, then be incident to described exiting surface 311 after entering optical lens 30 inside, after described exiting surface 311 reflects, above axes O X, be partial to axes O X outgoing a little again.Free form surface so through described incidence surface 321 and exiting surface 311 coordinates, and the angle with the light deflection axes O X of larger rising angle that LED source 20 is sent reduces.Thus increase luminescence unit 10 and there is the side direction light strong compared with the low light level towards axes O Y skew, reduce the shooting angle of side direction light, make the illumination of whole luminescence unit 10 evenly.
Refer to Fig. 3, in the second cross section or be parallel in other plane in the second cross section, because the central axis O1Y1 of described exiting surface 311 is partial to axes O Y side, i.e. OZ axle forward, the central axis O2Y2 of described incidence surface 321 is partial to the opposite side of axes O Y, i.e. OZ axle negative sense, thus the exit path of light that LED source 20 sends to be not in relation to axes O Y symmetrical.Most light that LED source 20 like this sends are above axes O Z and the direction outgoing of deflection axes O Z forward; The light of few part is from the direction outgoing of being partial to axes O Z negative sense.
In addition, because the radius of curvature of each free form surface on the exiting surface 311 of described end face 31 is successively decreased gradually along the forward of axes O 1Y1; On the incidence surface 321 of described bottom surface 32, the radius of curvature of each free form surface is successively decreased gradually along the negative sense of axes O Z.
Therefore the light of deflection OZ axle forward that LED source 20 sends can be divided into two kinds of situations: LED source 20 send become with axes O Y shape less rising angle (as, 0 ° to X °, 0<X<90 °) light, namely, the forward light of deflection axes O Y, as light C; The light of what LED source 20 sent become with axes O Y shape larger rising angle (e.g., X ° to 90 °, 0<X<90 °), that is, be partial to the side direction light of axes O Z forward, as light D.Light C roughly moves towards identical with light B with the light A on the first cross section respectively with light D's.
Light C above axes O Z and to enter optical lens 30 inner in the direction of being partial to axes O Z forward a little, is then incident to described exiting surface 311 after described incidence surface 321 reflects, after described exiting surface 311 reflects further towards axes O Z forward bias from.Free form surface so through described incidence surface 321 and exiting surface 311 coordinates, the angle that the light with less rising angle that LED source 20 is sent is partial to the side of described luminescence unit 10 increases, thus make this luminescence unit 10 have the forward light strong compared with high light towards axes O Z forward migration, weaken forward and go out luminous intensity, be overall light homogenising, increase the lighting angle of the forward of the axes O Z of luminescence unit 10 simultaneously.
Light D is partial to the forward of axes O Y a little after described incidence surface 321 reflects, and is incident to described exiting surface 311 after then entering optical lens 30 inside, after described exiting surface 311 reflects, be partial to axes O Z forward a little to outgoing again above axes O Z.Free form surface so through described incidence surface 321 and exiting surface 311 coordinates, and the angle with the light deflection axes O Z of larger rising angle that LED source 20 is sent reduces.Thus increase luminescence unit 10 and there is the side direction light strong compared with the low light level towards axes O Y skew, reduce the shooting angle of side direction light, make the illumination of whole luminescence unit 10 evenly.
Same, the light of the deflection OZ axle negative sense that LED source 20 sends also can be divided into two kinds of situations: LED source 20 send become with axes O Y shape less rising angle (as, 0 ° to X °, 0<X<90 °) light, namely, the forward light of deflection axes O Y, as light E; The light of what LED source 20 sent become with axes O Y shape larger rising angle (e.g., X ° to 90 °, 0<X<90 °), that is, be partial to the side direction light of axes O Z negative sense, as light F.
Light E above axes O Z and to enter optical lens 30 inner in the direction of being partial to axes O Y forward a little, is then incident to described exiting surface 311 after described incidence surface 321 reflects, after described exiting surface 311 reflects further towards axes O Y forward bias from.Light F is partial to the forward of axes O Y a little after described incidence surface 321 reflects, and is incident to described exiting surface 311 after then entering optical lens 30 inside, after described exiting surface 311 reflects, be partial to the outgoing of axes O Z forward a little again above axes O Z.
So make on the second cross section, LED source 20 send the side of being partial to luminescence unit 10 of light high degree, namely the forward side of axes O Z, increases the lighting angle of this sidelight line simultaneously.
When luminescence unit 10 of the present invention is applied to street lamp, by the lens component of the axes O Z negative sense in the second cross section towards lamppost, by the lens component of the axes O Z forward in this plane towards highway, now, on first cross section, the lens component of axes O Y both sides is respectively towards the longitudinal two ends of highway, so make the light of luminescence unit 10 on highway, have an approximate rectangular illumination range, and the length a of this rectangle is about 3:1 with the ratio of width b, as shown in Figure 4.
Compared to prior art, luminescence unit 10 of the present invention by arranging described optical lens 30 above LED source 20, utilize the incidence surface 321 of described optical lens 30 and the structure of exiting surface 311 and the cooperation of free form surface, on the second cross section, by the light of luminescence unit 10 side guiding towards its opposite side, on the first cross section, expand the light irradiating angle of luminescence unit 10 simultaneously.So, the light sent LED source 20 carries out rationally effective distribution, thus obtains the distribution curve flux of wide-angle, makes light type more wide, and optical field distribution is more even, thus the range of exposures of luminescence unit 10 is increased, illumination evenly.
