Detailed description of the invention
Fig. 1 is the schematic cross-section of lens 100 according to an embodiment of the invention, as shown in Figure 1, it is rotational symmetric that lens 100 can be designed to about optical axis X, and can be formed by optical plastic or glass manufacture, not only reduce manufacturing cost like this, also can ensure that these lens 100 have good optical property.The bottom surface 1 that lens 100 have end face 2 and are oppositely arranged with end face 2, the plane of incidence 41 of these lens and reflecting surface 42 and the recessed region 3 for holding light source 5 is defined between bottom surface 1 and end face 2, such recessed region 3 is designed to be hollow, as seen from the figure, this plane of incidence comprises two parts, i.e. the plane of incidence 41 and reflecting surface 42.
Composition graphs 2, Fig. 2 is the index path of lens 100 according to an embodiment of the invention.Central authorities in bottom surface 1 can be provided with LED light source 5, and it is efficient and have the advantages such as long life cycle that LED light source has low energy, and the light like this from LED light source 5 can be injected lens 100 and arrive the plane of incidence after entering bottom surface 1.Wherein, the first light L1 from light source 5 can directly be injected on the plane of incidence 41, now the first light L1 can on the plane of incidence 41 by refraction injection to end face 2, and again after the refraction of end face 2 outgoing to the outside of lens 100.According to the difference of the design of the profile of the plane of incidence 41, such as in cross section, can be designed to semicircle, rectangle and trapezoidal in any one, the profile of certain plane of incidence 41 is not limited to above-mentioned shape, the similar shape reaching same or similar function all can be used for the profile being designed to the plane of incidence 41, different Light distribation can be had from the first light L1 of the plane of incidence 41 incidence, thus after eventually passing through end face 2 outgoing, form the Light distribation of the emergent light L1 ' of different-effect.It should be noted that, end face 2 comprises two parts, be respectively exit facet 21 and stripping surface 22, (hereafter will elaborate) of outgoing after the refraction only passing through exit facet 21 after the refraction through the plane of incidence 41 from the first light L1 of light source 5, so the light that there is no from light source 5 is through stripping surface 22 outgoing, such stripping surface 22 is connected to exit facet 21 and the bottom surface 1 of end face 2, whole lens 100 are made to have coherent circumference, such design is to the design providing a kind of comparatively easily profile of processing or manufacture in the process manufacturing lens 100, such as be convenient to the process of the demoulding.
As shown in Figure 1, the reflecting surface 42 as another plane of incidence is arranged on the plane of incidence 41 around, and is rotational symmetric around the optical axis X that this plane of incidence 41 is relevant to lens 100.From the cross section of these lens 100, this reflecting surface 42 can be set to have two parts, Part I 421 and Part II 422, wherein, Part I 421 can be set to linearity in cross section, and Part II 422 is also set to linearity, and such first and second parts 421,422 define the cross section profile of broken line on the whole simultaneously.Now, Part I 421 can realize the effect limited from the first light L1 of same light source 5 and the boundary of the second light L2, can not be incident on reflecting surface 42 through the first light L1 of the plane of incidence 41 incidence, such first light L1 only can form final forward direction emergent light L1 ' by the plane of incidence 41.Based on this, from the second light L2 of light source 5 when being mapped to reflecting surface 42, because now reflecting surface 42 employs such as mirror face reflection coating and processes, such second light L2 can directly be penetrated towards the direction of bottom surface 1 by after reflecting surface 42 all reflection, and eventually passes through bottom surface 1 outgoing formation emergent light L2 '.According to such design, the light part L1 of light source 5 can be formed on first direction by the plane of incidence 41, namely be the Light distribation of forward direction, another part L2 can be backward through reflecting to form of reflecting surface 42, namely be the Light distribation forming other after the second direction outgoing relative with first direction, and finally define the illuminating effect of omnidirectional lighting according to the Light distribation of these zoness of different.
Can find out according to Fig. 1, in the cross section of lens 100, volume included by the plane of incidence 41 and reflecting surface 42 difference or the size of surface profile, by the ratio between the described volume of both changes or size, thus realize the ratio of the luminous flux changed between the first emergent light L1 ' in first direction outgoing and the second emergent light L2 ' in second direction outgoing.
In addition, it should be noted that, in unshowned embodiment, two parts 421,422 of the reflecting surface 42 of lens 100 also can be designed to linearity and SPL respectively, like this can finally to second light L2 formed different-effect or the reflecting effect of different shooting angle, Light distribation and the shooting angle of the emergent light of the emergent ray L2 ' such as regulating light source 5 can be realized whereby, the illumination zone of so final adjustable omnidirectional lighting after lens 100 process.
In another unshowned embodiment, two parts 421,422 of the reflecting surface 42 of lens 100 also can be designed to integration, namely from the cross section of lens 100, two parts 421,422 are designed to a such as SPL, the manufacture process of lens 100 can be simplified so to a certain extent, and the effect of good omnidirectional lighting can be reached.
In addition, based on above-mentioned lens 100, also provide a kind of lighting device 200, show the schematic cross-section of lighting device 200 according to an embodiment of the invention see Fig. 3, Fig. 3.According to such design, lens 100 can be arranged at the top of lighting device 200, receive the light from LED light source, namely what form forward direction is from the bottom surface of lens 100 to the illumination the direction of end face, namely also form backward is from the end face of lens 100 to the illumination the direction of bottom surface simultaneously, thus defines the Light distribation of the omnidirectional lighting of this lighting device 200.In this lighting device 200, in order to make traditional heat abstractor 6 designed on the outside of lighting device 200 can not stop or cover from lens 100 rear to light, this heat abstractor 6 is designed with heat radiating fin 61, and it is gradually near the first edge 611 that optical axis X tilts that the design of this heat radiating fin 61 has one bottom lighting device 200 on the direction at top, like this, if avoid this first edge 611 when being designed to level, from the result that the downward light of lens 100 is stopped by this heat radiating fin 61 or covers, overall omnidirectional lighting effect is reduced or is deteriorated.
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 amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
