The specific embodiment
Fig. 1 is that schematic perspective view, Fig. 2 of the lens of one embodiment of the invention is the generalized section along the lens of the A-A hatching of Fig. 1.Please be simultaneously with reference to figure 1 and Fig. 2; Lens 130 have a holding part 132, one first exiting surface 134 and one second exiting surface 136; Wherein first exiting surface 134 is positioned at holding part 132 tops; And second exiting surface 136 is around first exiting surface 134 and be positioned at the outside of holding part 132, and first exiting surface 134 and second exiting surface 136 are concave surface.In detail, holding part 132 is in order to let light source be placed in wherein, and wherein the lens 130 of present embodiment mainly are the ranges of application in order to improvement directive property light source, so lens 130 overlay on the light-emittingdiode in order to cover.
The holding part 132 of aforesaid lens 130 has a top incidence surface 132a and a side incidence surface 132b; Wherein incidence surface 132a in top is a plane; And side incidence surface 132b is around top incidence surface 132a, and top incidence surface 132a and the common space that forms of side incidence surface 132b are in order to a ccontaining luminous dipolar object light source.
In addition; First exiting surface 134 has one first sub-exiting surface 134a and one second sub-exiting surface 134b; Wherein the first sub-exiting surface 134a is a plane; And be parallel to top incidence surface 132a, and the second sub-exiting surface 134b is connected around the first sub-exiting surface 134a and with second exiting surface 136, and the second sub-exiting surface 134b of present embodiment is the inclined-plane.In other words, the section of first exiting surface 134 roughly is a funnel-form.
Moreover; Second exiting surface 136 can have one the 3rd sub-exiting surface 136a and one the 4th sub-exiting surface 136b; Wherein the 3rd sub-exiting surface 136a is connected between first exiting surface 134 and the 4th sub-exiting surface 136b, and the side incidence surface 132b of the 4th sub-exiting surface 136b and holding part 132 is coaxial.
Fig. 3 is the sketch map of light fixture of the lens of application drawing 1, and Fig. 4 is the light path sketch map of light in lens that luminous dipolar object light source sent.Please above-mentioned lens 130 be applied in the light fixture 100 simultaneously with reference to figure 3 and Fig. 4, wherein this light fixture 100 comprises a lampshade 110, a pedestal 120, above-mentioned lens 130 and a luminous dipolar object light source 140.Pedestal 120 fits together with lampshade 110; And lens 130 are disposed on the pedestal 120; And be positioned at lampshade 110, luminous dipolar object light source 140 is disposed in the holding part 132 of lens 130, and the light-emitting area of luminous dipolar object light source 140 towards the top of holding part 132 incidence surface 132a.
When luminous dipolar object light source 140 is luminous; Light can get into lens 130 from the top incidence surface 132a and the side incidence surface 132b of the holding part 132 of lens 130; Wherein because luminous dipolar object light source 140 is the light source of directive property, so most light is to get into the lens 130 from top incidence surface 132a.
The light that gets into lens 130 partly is projected to bright dipping behind the 3rd sub-exiting surface 136a and the 4th sub-exiting surface 136b of second exiting surface 136; And ray cast to the first exiting surface 134 of part; Wherein be projected to the light of the first sub-exiting surface 134a; Because go into the relation of angular, can directly penetrate outside lens 130; And the light that is projected to the second sub-exiting surface 134b is too because go into the relation of angular, after the second sub-exiting surface 134b reflection, and bright dipping behind the 3rd sub-exiting surface 136a.
Can find out by Fig. 4; If first exiting surface 134 is a plane; Originally the light that sends of luminous dipolar object light source 140 is projected to just directly outgoing behind first exiting surface 134; Make the angle of visibility scope of light fixture 100 can concentrate on the light emission direction of luminous dipolar object light source 140, and have the bright dark uneven problem that brightness concentrates on light fixture 100 the place aheads.The lens 130 of present embodiment are through improvement; Let first exiting surface 134 have and press from both sides the second sub-exiting surface 134b that an angle is the inclined-plane for the first sub-exiting surface 134a on plane and with the first sub-exiting surface 134a; Wherein the diameter of the first sub-exiting surface 134a is for being equal to or greater than 0.5 millimeter, so that the light that luminous dipolar object light source 140 sends still can be via first sub-exiting surface 134a (being on the light emission direction) bright dipping.In addition, the second sub-exiting surface 134b more can penetrate after being projected to the 3rd sub-exiting surface 136a again after the light reflection that is projected to the second sub-exiting surface 134b, to promote the light fixture 100 angle of visibility scope when luminous.Fig. 5 and Fig. 6 are the sketch map of angle of visibility scope of the light fixture of Fig. 3, and wherein Fig. 5 is the figure that obtains with software simulation, and Fig. 6 is the resulting figure of actual measurement.Can know that by Fig. 5 and Fig. 6 the angle of visibility scope of the light fixture 100 of present embodiment can reach about positive and negative 110 degree.With 0 degree during as the place ahead of light fixture 100; The user can also see that from the rear of light fixture 100 light fixture 100 is shinny; Having improved existing directive property light source can only be applied in the fixing light fixture of direction of illumination; Now lets candle light formula light fixture also can use light-emittingdiode as light source through the application of the lens 130 of present embodiment.In addition, on the whole, light fixture 100 also has uniform brightness.
Though the foregoing description is to be that the inclined-plane is the example explanation with the second sub-exiting surface 134b; But in other unshowned embodiment; The second sub-exiting surface 134b also can be curved surfaces such as convex surface or concave surface; Light portion is penetrated and partial reflection as long as can reach, get final product with the purpose that increases the lighting angle scope.
In above-mentioned explanation; Recessed be meant recessed in lens 130; And protruding being meant protrudes from outside the lens 130; But it is relative notion that those of ordinary skill in the art should know the described concave, convex of the above embodiments, and the present invention is subject to explanatory note of the foregoing description or illustrated expression.
In sum, the simple advantage of the moulding of lens of the present invention.Moreover; These lens and the luminous dipolar object light source collocation with directive property are used; Can improve the angle of visibility scope of luminous dipolar object light source; Luminous dipolar object light source also can be applied to more promote the application of luminous dipolar object light source in the light fixture of decoration type, and let the use light-emittingdiode also can have uniform brightness as the light fixture of light source.
Though the present invention discloses as above with embodiment, so it is not in order to limiting the present invention, any under the those of ordinary skill of technical field, when can doing a little change and retouching, and do not break away from the spirit and scope of the present invention.
