Therein in an embodiment, with the first axis 121 and light-emitting component 110 of optically focused matrix 120The intersection point of light-emitting area is benchmark initial point, and benchmark initial point and the optically focused plane of incidence 122 optional positions are connected to form incidentLight, the first axis 121 of incident ray and optically focused matrix 120 forms incident angle, and incident angle is largeIn the time of preset value, the light that light-emitting component 110 sends is incident to spotlight camber 124, and incident angle is less than in advanceIf when 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 gatheringIn the middle of the light of light-emitting face 126 outgoing occurs, bright both sides are dark, the problem that namely bright dipping is inhomogeneous. Therefore closeIt is 25 degree to 35 degree that reason arranges preset value.
In embodiment as shown in Figure 2, preset value is 30 degree, and incident angle is at 0 degree to 30 degreeBetween, the light that light-emitting component 110 sends is directly into being incident upon optically focused exit facet 126. Incident angle is at 30 degreeBetween 90 degree, the light that light-emitting component 110 sends is incident to spotlight camber 124. Certainly preset value,Also can be other numerical value, be uniformly distributed through the light of optically focused matrix 120 outgoing as long as can ensure.
Refer to Fig. 2, in an embodiment, the optically focused plane of incidence 122 comprises the first optically focused plane of incidence therein1220 and second the optically focused plane of incidence 1222, the first optically focused planes of incidence 1220 and the second optically focused plane of incidence 1222 shapesBecome accommodation hole 128, taking the first axis 121 of optically focused matrix 120 as benchmark, the first optically focused plane of incidence 1220Arrange around the first axis 121 annulars, the first optically focused plane of incidence 1220 and the second optically focused plane of incidence 1222Center is all positioned at first axis 121, the first optically focused planes of incidence 1220 towards spotlight camber 124, the secondThe 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, light-emitting component 110 send onePart light can be inducted into and be incident upon spotlight camber 124 by the first optically focused plane of incidence 1220, more anti-by optically focusedPenetrate face 124 and reflex to 126 outgoing of optically focused exit facet. The second optically focused plane of incidence 1222 is just to optically focused exit facet 126,Another part light that light-emitting component 110 sends can be poly-directly into being incident upon by the second optically focused plane of incidence 1222Light-emitting face 126. 1222 of the first optically focused plane of incidence 1220 and the second optically focused planes of incidence are controlled angle of incidence of lightThe effect of degree. The first optically focused plane of incidence 1220 arranges around the first axis 121 annulars, the first optically focused plane of incidence1220 and the center of the second optically focused plane of incidence 1222 be all positioned on the first axis 121, can make light-emitting component110 light that send can be uniformly distributed, and in meeting distance-light lighting demand, are conducive to improve outgoingThe uniformity of light, has further improved the reliability using.
Refer to Fig. 2, in an embodiment, optically focused exit facet 126 comprises and can outgoing reflect through optically focused thereinThe first optically focused exit facet 1260 of the light that face 124 reflects, and directly outgoing through the second optically focused plane of incidenceThe second optically focused exit facet 1262, the second optically focused exit facets 1262 of the light of 1222 incidents are just to the second optically focusedThe plane of incidence 1222, and along arranging away from the second optically focused plane of incidence 1222 direction projections, the first optically focused exit facet1260 one end are connected with spotlight camber 124 ends, and 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 being set and the second optically focused exit facet 1262, the second optically focused go outPenetrate face 1262 along arranging away from the second optically focused plane of incidence 1222 direction projections, thereby can will be entered by the second optically focusedPenetrate face 1222 and disperse outgoing directly into the light that is incident upon the second optically focused exit facet 1262 being convexly equipped with in scope, keep awayThe dark problem in bright both sides in the middle of exempting to be occurred by the light of optically focused exit facet 126 outgoing, has further improved by gatheringThe uniformity of light-emitting face 126 emergent raies. In the present embodiment, this second optically focused exit facet 1262Be arc surface, ensure uniform-illumination.
Refer to Fig. 2 and Fig. 3, in an embodiment, the incidence surface 132 of polarization matrix 130 also wraps thereinDrawing together the second incidence surface 1322, the second incidence surfaces 1322 is serrated face setting, and the second incidence surface 1322 is positioned atOne incidence surface 1320 is near a side of optically focused matrix 120, and the depth of section of the first incidence surface 1320 is not less thanThe depth of section of the second incidence surface 1322. So, along with the curvature of the first incidence surface 1320 is from the first light inletThe end of face 1320 increases gradually along close optically focused matrix 120 directions, the first incidence surface 1320 degree of crookIncreasing, with the spacing of exiting surface 134, thickness also will be increasing, thus the light of outgoing instituteNeeding also can be more and more thicker through the thickness of polarization matrix 130, therefore the first incidence surface 1320 is near optically focused matrix 120A side the second incidence surface 1322 is set, this second incidence surface 1322 is serrated face, can dwindle incidence surface 132With the spacing difference of exiting surface 134, in ensureing that light deflects, be conducive to improve light everywhereThe uniformity of 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 atThe first incidence surface 1320, near a side of optically focused matrix 120, is mainly used in controlling light and deflects. For keeping awayExempt from the too large uniformity that affects distance-light illumination of ratio that the second incidence surface 1322 takies incidence surface 132, therefore closeThe depth of section that reason arranges the first incidence surface 1320 is not less than the depth of section of the second incidence surface 1322. As Fig. 2Shown in, 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 first incidence surface 1320 and bright dippingThe spacing of face 134, also can realize the uniformity of light after polarization matrix 130 outgoing.
In embodiment as shown in Figure 2, the light that enters the second incidence surface 1322 for guarantee can be inclined to one sideTurn 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 near the first incidence surfaceA side of 1320, the first serrated face and the crossing formation of the second serrated face sawtooth, the first serrated face is horizontally disposed with,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, therein in an embodiment, if the second incidence surface 1322 depth of sectionsOversize, cause unavoidably the light deflecting too much to affect the uniformity of distance-light illumination. If second entersLight face 1322 depth of sections are too short, thicker the causing of polarization matrix 130 thickness of passing because of part light unavoidablyBright dipping is inhomogeneous. Therefore the second axis 131 of the second incidence surface 1322 and polarization matrix 130 is rationally setDistance be not more than incidence surface 132 overall depth of section 1/4th. As shown in Figure 2, incidence surface 132 fromVertical distance is top to bottm the overall depth of section of incidence surface 132.
