The specific embodiment
As shown in Figure 1, Fig. 1 shows according to the sectional view of lens 100 of the present invention.According to such design, lens 100 are designed to rotational symmetric on the whole, can be in the final photodistributed requirement that forms rotational symmetric emergent light after lens 100 to meet the light making from light source 1.And these lens 100 are designed to make by for example optical plastic or glass, not only with low cost, but also guarantee that such lens 100 have tree-like profile, the light beam of light source 1 is spent and distributed along the surrounding 360 with the lighting device of lens 100, thereby there is efficient and reliable optical characteristics.
As shown in Figure 1, lens 100 comprise bottom surface 2 and have the protrusion surface 3 in three different regions, are respectively the first subregion 31, the second subregion 32 and the 3rd subregion 33.In addition, the central authorities in the bottom surface 2 of these lens 100 are provided with light source 1, and such light source 1 can be designed as for example LED light source, to realize the advantages such as energy-efficient and long-time service life.Towards deviating from the direction of light source 1, bottom surface 2 also comprises recessed region 4, such recessed region 4 can be designed to for example hemispherical, from the light that is contained in the light source 1 in recessed region 4, can vertical incidence angle be incident upon on the surface of recessed region 4 like this, and using the surface of recessed region 4 and enter lens 100 as the plane of incidence 5.
In addition, Fig. 1 also shows, and the first subregion 31 of lens 100 can be designed to for example only have one as the surface of exit facet, and like this, the first light L1 of light source 1 can directly be refracted outgoing after the first subregion 31.Wherein, in cross section, this first subregion 31 can be designed to have the profile of SPL, to guarantee efficient optical property, meets the light distribution requirement of the emergent light of expection, and realizes and process cheaply and manufacture.The second subregion 32 and the 3rd subregion 33 all have respectively for example two surfaces, wherein, the form setting that the second subregion 32 can be organized, the second subregion 32 has many groups, every group all has respectively first surface 321 and second surface 322, and forms predetermined angle between first surface 321 and second surface 322, as shown in Figure 1, from cross section, can upwards form the profile of the wedge angle with a plurality of for example dentations in the week of lens like this.A plurality of groups in the second subregion 32 all can for example be designed along optical axis directions X stacking, in cross section, first surface 321 and second surface 322 can be designed to have the profile of SPL, and upwards forming for example structure of the profile of dentation that has of multilayer the week of lens 100, can utilize the light distribution property of light source 1 like this, collect fully the light of light source 1, and the second light L2 of light source 1 is guided to different directions, with finally realize mainly after for example to direction on the illuminating effect of wide scope.
Top area at lens 100 is also designed with the 3rd subregion 33, the 3rd subregion 33 is like this designed to have two different surfaces, the 3rd the 331 and the 4th surface 332, surface, the 3rd light L3 of light source 1 can be guided to different directions by the 331 and the 4th surface 332, the 3rd surface, thereby for example on main forward direction, is realizing the effect of throwing light on.Wherein, the 3rd the 331 and the 4th surface 332, surface also can be designed to have the profile of SPL, and in cross section, the direction from bottom surface 2 to protrusion surface 3, the 3rd surface 331 is gradually near the optical axis X of lens 100, and the 4th surface 332 is gradually away from optical axis X's.
Fig. 2 shows the light path schematic diagram according to lens 100 of the present invention.As shown in Figure 2, the first light L1 outgoing after the first subregion 31 through lens 100 from light source 1, this the first subregion 31 can be designed to have the profile of SPL, such the first light L1 can directly be refracted and form the first emergent ray L1 ', this first emergent ray L1 ' provides the main illumination on lateral of lens, illumination to backward direction is provided simultaneously, has guaranteed that lens 100 omnidirectional's directions illuminating effect of last minute is met.
From the second light L2 outgoing after the second subregion 32 through lens 100 of light source 1, the second subregion 32 also can be designed to have the profile of SPL.Wherein, the second subregion 32 comprises two surfaces towards different directions, first surface 321 and second surface 322, and first surface 321 and second surface 322 all can be realized respectively the effect of reflection and refraction, for example a part of the second light L2 is diverted towards second surface 322 transmittings after the reflection through first surface 321, and running into second surface 322 by superrefraction outgoing, similarly, another part of the second light L2 is diverted towards first surface 321 transmittings after the reflection through second surface 322, and running into first surface 321 by superrefraction outgoing, like this, finally through the second subregion 32, form the second emergent light L2 ' of the wide range lighting effect with different directions, the second emergent ray L2 ' like this can be particularly towards rear to outgoing in direction, formed so the backward directional lighting effect in omnidirectional's direction, certainly small part the second emergent ray L2 ' has formed the illumination in side direction simultaneously.
The 3rd light L3 of light source 1 forms the 3rd emergent ray L3 ' after the 3rd subregion 33 outgoing through lens 100.The 3rd subregion 33 comprises that two towards two surfaces of different directions, the 331 and the 4th surface 332, the 3rd surface, and similar with the second subregion, the 3rd light L3 is guided to different direction outgoing by these two surfaces.In other words, for example a part of the 3rd light L3 is diverted towards the 4th surface 332 transmittings after the reflection through the 3rd surface 331, and running into the 4th surface 332 by superrefraction outgoing, similarly, another part of the 3rd light L3 is diverted towards the 3rd surface 331 transmittings after the reflection through the 4th surface 332, and running into the 3rd surface 331 by superrefraction outgoing, like this, finally through the 3rd subregion 33, form the 3rd emergent light L3 ' of the wide range lighting effect with different directions, the 3rd emergent ray L3 ' like this can be particularly in outgoing on forward direction, formed like this forward direction illuminating effect in omnidirectional's direction, certainly small part the second emergent ray L2 ' has formed the illumination in side direction simultaneously.In addition, based on the second light L2, be through another, to reflect outgoing again through any one reflection in first surface 321 or second surface 322, first surface 321 and second surface 322 have been realized similar or identical effect, are interchangeable so.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
