Shown in Fig. 7 a, 7b, it is the arrangement schematic diagram of the first light source on light source module in the embodiment of the present invention.Wherein, can find out that the quantity of the first light source 42 of annular arrangement can adjust as required.The distribution angle defining the first light source 42 is: the line angulation between two adjacent the first light sources 42 and the ring heart.Then, in Fig. 7 a, the quantity of the first light source 42 is 20, and its distribution angle is 18 °, and in Fig. 7 b, the quantity of the first light source 42 is 40, and its distribution angle is 9 °.In the embodiment of the present invention, the hot spot phenomenon that draw direction in order to the first lens 32 eliminating ring-type can not be controlled light and produce, first incidence surface 322 of described first lens 32 or the first exiting surface 324 can be formed with concaveconvex structure, and this concaveconvex structure can comprise by the erosion line structure of erosion line technique formation, by one or more in frosting technology formation frosted structure.In the present embodiment, by above-mentioned erosion line structure or frosted structure, the dispersion angle of the emergent ray that the incident ray that above-mentioned first light source 42 can be made to produce obtains after through these first lens reaches certain requirement.
With reference to shown in Fig. 8, it is distribution curve flux schematic diagram in the embodiment of the present invention.About the definition of above-mentioned dispersion angle, refer to: after a parallel ray beam incides described first lens 32, determine the emergent ray of 1/2 intensity corresponding to half of exiting light beam intensity maximum, then described dispersion angle refer to two 1/2 intensity emergent ray formed by angle.For example, in the distribution curve flux of Fig. 8, if the maximum intensity of emergent ray is 1 (light of largest light intensity concentrates on the normal position of the first lens), so the emergent ray of 1/2 intensity be distributed in above-mentioned normal position ± position of 2.5 °, therefore now described dispersion angle is 5 °.
In order to obtain uniform hot spot, in the present embodiment, described erosion line structure or frosted structure make the distribution angle positive correlation of the dispersion angle of the first lens 32 and described first light source 42.That is, when distribution angle diminishes, correspondingly need the size reducing above-mentioned dispersion angle, and when distribution angle becomes large, correspondingly need the size increasing above-mentioned dispersion angle.Such as: when distribution angle is 18 °, above-mentioned dispersion angle can be 12 °, and when distribution angle is 9 °, above-mentioned dispersion angle can be 6 °.
With reference to shown in Fig. 9, it is the index path of the incident ray scioptics of light source in the present invention.The incidence surface of these lens and exiting surface all have convergence effect to light.Wherein, the definition incident ray of light source and the angle of normal are a, the incident ray angle that reflects light and the normal obtained by incidence surface of definition light source is b, and defining and reflecting above by incidence surface the angle that the light that obtains reflects by exiting surface light and the normal obtained again is c.Usually, above-mentioned angle a is 0 ° ~ 90 °, and after incidence surface refraction, it is 0 ° ~ 65 ° that above-mentioned angle b converges, and after exiting surface refraction, it is 0 ° ~ 50 ° that above-mentioned angle c converges.With reference to shown in Figure 10, it is the index path of the light transmission lens combination that first, second light source is launched.If the light that definition bright dipping light type is light source to be generated is at the maximum angle through the emergent ray after said lens (first lens 32 or the second lens 31) refraction and normal.For example, the emergent ray that the light launched of the first light source 42 in first lens 32 obtains after by the first incidence surface 322 of the first lens 32 and the refraction of the first exiting surface 324 is β 1 with the maximum angle of normal, and the maximum angle of the emergent ray that the light launched of the secondary light source 43 in the second lens 31 is obtained after being reflected by the second incidence surface of the second lens 31 and the second exiting surface and normal is β 2.Therefore the bright dipping light type after light transmission first lens 32 that the first light source 42 is launched is consistent with the bright dipping light type after light transmission second lens 31 that secondary light source 43 is launched, and can be understood as above-mentioned angle β 1 equal with above-mentioned angle β 2.Visible, due in embodiments of the present invention, first lens 32 are arranged to circular, point-like is arranged to by second lens 31, if by identical for face, the cross section type that second cross section corresponding with the second lens 31 of point-like be arranged to by face, the cross section type in the first cross section of the first circular lens 32 correspondence, be then difficult to reach the first light source 42 through the bright dipping light type after the first lens 32 and secondary light source 43 through the on all four effect of bright dipping light type after the second lens 31.For this reason, in the present embodiment, by inconsistent for face, the cross section type that second cross section corresponding with above-mentioned second lens 31 be arranged to by face, the cross section type in the first cross section of above-mentioned first lens 32 correspondence, thus the luminous intensity distribution light type of both realizations is identical.Based on above content, the present invention by being arranged to inconsistent by face, the cross section type of the first lens 32 and the second lens 31, thus reaches the first lens 32 and the second lens 31 possess identical light distribution effect (namely above-mentioned angle β 1 is equal with above-mentioned angle β 2).Usually, due to the difference of manufacturing process, second lens 31 of point-like are rotational symmetric types, and the first lens 32 of ring-type are not rotational symmetric types, suppose that the maximum angle β 2 of the emergent ray that incident ray obtains after through the second lens 31 of point-like and normal is 60 °, if face, the cross section type of the first lens 32 of ring-type is arranged to identical with face, the cross section type of these the second lens 31, then may the maximum angle β 2 of the emergent ray that obtains after through the first such lens 32 of incident ray and normal usually be greater than 60 ° (such as 70 ° ~ 80 °).For these reasons, the present invention in order to make the first lens 32 of ring-type and point-like the second lens 31 possess identical light distribution effect, then can by changing face, the cross section type of above-mentioned first lens 32 in technique, the emergent ray that incident ray is obtained after through the first lens 32 and the maximum angle β 2 of normal maintain 60 °.In various embodiments of the present invention, the mode changing face, the cross section type of the first lens 32 can comprise the first incidence surface 322 of change first lens 32 and the curvature of the first exiting surface 324, or change the height of the first lens 32, or change the width etc. of the first lens 32, the present invention is not construed as limiting.
