As shown in Figure 1, a kind of LED optical system 100, comprises the light-emitting component 110 for generation of light that sets gradually, controls the concentrated optically focused matrix 120 of light and control the polarization matrix 130 that light deflects in preset range.Light-emitting component 110 can be that bright dipping mode is the LED light source of lambert's body bright dipping, and light-emitting component 110 also can be other light source certainly, as long as can realize the object of luminous lighting.Optically focused matrix 120 can the adjustable setting according to different lighting demands from the spacing of polarization matrix 130.
Optically focused matrix 120 comprises the optically focused plane of incidence 122 of the light that receives self-emission device 110, be incident to the spotlight camber 124 of the light of the optically focused plane of incidence 122 for reflecting part, and for outgoing the optically focused exit facet 126 through the light of optically focused matrix 120, spotlight camber 124 is between the optically focused plane of incidence 122 and optically focused exit facet 126, the optically focused plane of incidence 122 and spotlight camber 124 are all falling into optically focused exit facet 126 towards the orthographic projection of optically focused exit facet 126 directions, take optically focused plane of incidence 122 center and optically focused exit facet 126 center connecting line as the first axis 121.
Specifically as shown in Figure 1, this spotlight camber 124 can be by a line segment around forming with spaced the first axis 121 rotation of this line segment, being centered close on the first axis 121 of light-emitting component 110.In light by 122 incidents of the optically focused plane of incidence, have the light of intersection point can be by 126 outgoing of optically focused exit facet after spotlight camber 124 reflection with spotlight camber 124, with spotlight camber 124 can be directly through 126 outgoing of optically focused exit facet without the light of intersection point.Wherein, the optically focused plane of incidence 122 and spotlight camber 124 are all falling into optically focused exit facet 126 towards the orthographic projection of optically focused exit facet 126 directions, cannot penetrate to prevent light-emitting component 110 from entering the light generation total reflection of optically focused matrix 120.According to total reflection principle, the ratio that is incident to the refractive index of angle that the incident ray of spotlight camber 124 and its normal at spotlight camber 124 form and optically focused matrix 120 is greater than 1.
Above-mentioned LED optical system 100, is disposed with light-emitting component 110, optically focused matrix 120 and polarization matrix 130.In use, the light that light-emitting component 110 sends is incident to optically focused matrix 120 by the optically focused plane of incidence 122, part light after spotlight camber 124 reflection by 126 outgoing of optically focused exit facet, another part light can be directly by 126 outgoing of optically focused exit facet, the light that light-emitting component 110 sends converges outgoing by optically focused exit facet 126, concentrate outgoing to control light, realize light and can project remote object, and irradiation brightness is high.Light after optically focused matrix 120 enters polarization matrix 130 by incidence surface 132, then through exiting surface 134 outgoing.Because incidence surface 132 comprises the first curved incidence surface 1320, the curvature of this first incidence surface 1320 increases setting gradually, can make the light outgoing that deflects in preset range, present asymmetric lighting effect, thereby meet the demand of distance-light illumination, without two sub-optical systems of distance light and dipped beam are set separately, simple in structure, be convenient to adjusting is installed, reliability is high.
Refer to Fig. 2, in an embodiment, the optically focused plane of incidence 122 is multiple therein, and the optically focused plane of incidence 122 is formed for accommodating the accommodation hole 128 of light-emitting component 110.So, light-emitting component 110 is contained in accommodation hole 128, this accommodation hole 128 is formed by multiple optically focused planes of incidence 122, thereby has avoided the characteristics of luminescence of light-emitting component 110 own, and the light that light-emitting component 110 sends may lose because of scattering.The incident mode that these optically focused planes of incidence 122 can make light-emitting component 110 form straight-down negative and side entering type and deposit, is conducive to improve utilization rate and the intensity of light, and without the space of placing light-emitting component 110 is set separately, has dwindled volume, simplified structure.
Therein in an embodiment, take the first axis 121 of optically focused matrix 120 with the intersection point of light-emitting component 110 light-emitting areas as benchmark initial point, benchmark initial point and the optically focused plane of incidence 122 optional positions are connected to form incident ray, the first axis 121 of incident ray and optically focused matrix 120 forms incident angle, when incident angle is greater than preset value, the light that light-emitting component 110 sends is incident to spotlight camber 124, when incident angle is less than preset value, the light that light-emitting component 110 sends is directly into being incident upon optically focused exit facet 126.If preset value is too little, cause unavoidably the light of optically focused exit facet 126 outgoing too concentrated.If preset value is too large, cause unavoidably the middle bright both sides of light generation of optically focused exit facet 126 outgoing dark, the problem that namely bright dipping is inhomogeneous.Be 25 degree to 35 degree therefore preset value is rationally set.
In embodiment as shown in Figure 2, preset value is 30 degree, and incident angle is between 0 degree to 30 degree, and the light that light-emitting component 110 sends is directly into being incident upon optically focused exit facet 126.Incident angle is between 30 degree to 90 degree, and the light that light-emitting component 110 sends is incident to spotlight camber 124.Certainly, preset value also can be other numerical value, is uniformly distributed through the light of optically focused matrix 120 outgoing as long as can guarantee.
Refer to Fig. 2, therein in an embodiment, the optically focused plane of incidence 122 comprises the first optically focused plane of incidence 1220 and the second optically focused plane of incidence 1222, the first optically focused plane of incidence 1220 and the second optically focused plane of incidence 1222 form accommodation hole 128, take the first axis 121 of optically focused matrix 120 as benchmark, the first optically focused plane of incidence 1220 arranges around the first axis 121 annulars, the center of the first optically focused plane of incidence 1220 and the second optically focused plane of incidence 1222 is all positioned at the first axis 121, the first optically focused plane of incidence 1220 is towards spotlight camber 124, the second optically focused plane of incidence 1222 is just to optically focused exit facet 126.
So, the first optically focused plane of incidence 1220 is towards spotlight camber 124, and a part of light that light-emitting component 110 sends can be inducted into and be incident upon spotlight camber 124 by the first optically focused plane of incidence 1220, then reflexes to 126 outgoing of optically focused exit facet by spotlight camber 124.The second optically focused plane of incidence 1222 is just to optically focused exit facet 126, and another part light that light-emitting component 110 sends can be by the second optically focused plane of incidence 1222 directly into being incident upon optically focused exit facet 126.The first optically focused plane of incidence 1220 and the second optically focused plane of incidence 1222 work to control angle of incidence of light degree.The first optically focused plane of incidence 1220 arranges around the first axis 121 annulars, the center of the first optically focused plane of incidence 1220 and the second optically focused plane of incidence 1222 is all positioned on the first axis 121, can make the light that light-emitting component 110 sends be uniformly distributed, in meeting distance-light lighting demand, be conducive to improve the uniformity of emergent ray, further improved the reliability using.
Refer to Fig. 2, therein in an embodiment, optically focused exit facet 126 comprises the first optically focused exit facet 1260 of the light can outgoing reflecting through spotlight camber 124, and directly outgoing through the second optically focused exit facet 1262 of the light of the second optically focused plane of incidence 1222 incidents, the second optically focused exit facet 1262 is just to the second optically focused plane of incidence 1222, and along arranging away from the second optically focused plane of incidence 1222 direction projections, first optically focused exit facet 1260 one end are connected with spotlight camber 124 ends, the other end is connected with the second optically focused exit facet 1262 ends, optically focused exit facet 126 falls into spotlight camber 124 in the orthographic projection of the first axis 121 of optically focused matrix 120.
So, by the first optically focused exit facet 1260 and the second optically focused exit facet 1262 are set, the second optically focused exit facet 1262 is along arranging away from the second optically focused plane of incidence 1222 direction projections, thereby can will in scope, disperse outgoing directly into the light that is incident upon the second optically focused exit facet 1262 being convexly equipped with by the second optically focused plane of incidence 1222, the dark problem in bright both sides in the middle of avoiding being occurred by the light of optically focused exit facet 126 outgoing, has further improved the uniformity by optically focused exit facet 126 emergent raies.In the present embodiment, this second optically focused exit facet 1262 is arc surface, guarantees uniform-illumination.
Refer to Fig. 2 and Fig. 3, therein in an embodiment, the incidence surface 132 of polarization matrix 130 also comprises the second incidence surface 1322, the second incidence surface 1322 is serrated face setting, the second incidence surface 1322 is positioned at the side of the first incidence surface 1320 near optically focused matrix 120, and the depth of section of the first incidence surface 1320 is not less than the depth of section of the second incidence surface 1322.So, along with the curvature of the first incidence surface 1320 increases along close optically focused matrix 120 directions gradually from the end of the first incidence surface 1320, the first incidence surface 1320 degree of crook are increasing, spacing with exiting surface 134, be that thickness also will be increasing, thereby the required thickness through polarization matrix 130 of the light of outgoing also can be more and more thicker, therefore the first incidence surface 1320 arranges the second incidence surface 1322 near a side of optically focused matrix 120, this second incidence surface 1322 is serrated face, can dwindle incidence surface 132 everywhere with the spacing difference of exiting surface 134, in guaranteeing that light deflects, be conducive to improve the uniformity of light outgoing after polarization matrix 130.
Because need meet the demand of distance-light through the light of polarization matrix 130 outgoing, the second incidence surface 1322 is positioned at the side of the first incidence surface 1320 near optically focused matrix 120, is mainly used in controlling light and deflects.For avoiding the second incidence surface 1322 to take the too large uniformity that affects distance-light illumination of ratio of incidence surface 132, therefore the depth of section that the depth of section of the first incidence surface 1320 is not less than the second incidence surface 1322 is rationally set.As shown in Figure 2, depth of section is the first incidence surface 1320 or the second incidence surface 1322 vertical height from top to bottom.It is pointed out that the second incidence surface 1322 also can be set, by changing the spacing of the first incidence surface 1320 and exiting surface 134, also can realize the uniformity of light after polarization matrix 130 outgoing.
In embodiment as shown in Figure 2, for the light that guarantees to enter the second incidence surface 1322 can deflection and uniform, each sawtooth that the second incidence surface 1322 forms and the spacing of exiting surface 134 are inconsistent, and each sawtooth includes the first serrated face and the second serrated face, the first serrated face is positioned at the side near the first incidence surface 1320, the first serrated face and the crossing formation of the second serrated face sawtooth, the first serrated face is horizontally disposed with, and the second serrated face is from its close optically focused matrix 110 direction settings in edge, one end crossing with the first serrated face.
Refer to Fig. 2 and Fig. 3, in an embodiment, if the second incidence surface 1322 depth of sections are oversize, cause unavoidably the light deflecting too much to affect the uniformity of distance-light illumination therein.If the second incidence surface 1322 depth of sections are too short, polarization matrix 130 thickness that pass because of part light are unavoidably thicker causes bright dipping inhomogeneous.Therefore rationally arrange the second incidence surface 1322 and the distance of the second axis 131 of polarization matrix 130 be not more than incidence surface 132 overall depth of section 1/4th.As shown in Figure 2, incidence surface 132 vertical distance is from top to bottom the overall depth of section of incidence surface 132.
