Embodiment
As depicted in figs. 1 and 2, the present invention provides a kind of collector lens 1, and it can be a solid transparent body 10.Solid transparent body 10 has an incidence surface 11 and an exiting surface 12 corresponding to incidence surface 11, and exiting surface 12 can be the spherical of evagination, and incidence surface 11 can be the arcwall face of indent.
The present invention can be installed in the light-path of optical device.In the course of work, can be from the light of light source (figure do not show) emission from incidence surface 11 incidents, reflect via the spherical exiting surface 12 of evagination again and assemble.Because incidence surface 11 is the arcwall face of indent, is gathered in the view field of incidence surface 11 through the light of incidence surface 11 surface reflections, thereby reduced light loss and light loss of causing outside incidence surface 11 view fields, and then improved spotlight effect.
As shown in Figure 2, the camber H1 of incidence surface 11 is less than the camber H2 of exiting surface 12.Collector lens 1 mainly can produce the light-ray condensing effect is the male part at spherical exiting surface 12 places, and the incidence surface 11 that is the indent arcwall face mainly is to be used to assemble reflection ray.Influence the light-ray condensing effect because the indent degree of incidence surface 11 is crossed senior general, thereby preferably can make the camber H2 of the camber H1 of incidence surface 11, so that realize the purpose of light-ray condensing less than exiting surface 12.
Preferably, the camber H1 of incidence surface 11 be less than or equal to incidence surface 11 arc radius R1 1/10, and the camber H1 of incidence surface 11 be less than or equal to incidence surface 11 bore d1 1/10.In other words, the indent degree of incidence surface 11 is less, to assemble the light that is reflected through incidence surface 11, also reduces the influence to spotlight effect simultaneously, to improve the optically focused reliability.In addition, the camber H2 of exiting surface 12 is more than or equal to 1/3 of the arc radius R2 of exiting surface 12, and the camber H2 of exiting surface 12 is more than or equal to 1/3 of the bore d2 of exiting surface 12.In other words, the evagination degree of exiting surface 12 is bigger, to shorten the light focusing distance, improves spotlight effect.
As depicted in figs. 1 and 2, solid transparent body 10 has side 13 between incidence surface 11 and exiting surface 12, and it can be used for increasing the thickness of solid transparent body 10, to increase the convenience on making.Collector lens 1 can be provided with along an optical axis X, and side 13 can be parallel to optical axis X, can reduce light like this and reflect the optical loss that solid transparent body 10 is caused via side 13.
The present invention also can provide a kind of lens combination of being made up of above-mentioned collector lens 1, and it comprises at least two collector lenses 1 that are arranged in order along the light ray propagation direction of optical axis X.In the actual use, the parameters such as radian of bore, exiting surface 12 and incidence surface 11 that can be through each collector lens 1 is set realize the secondary of light even the purpose of optically focused repeatedly, further to improve spotlight effect or to realize changing the purpose of light beam form.
As shown in Figure 3, it can be used as one of them embodiment that realizes changing the light beam form.For instance; The lens combination of present embodiment is mainly used in by a plurality of pointolite arrays forms the light source optical device of (figure does not show); With the collector lens over against light source is the first collector lens 1a; It has incidence surface 11a and exiting surface 12a, is the second collector lens 1b with the collector lens that is close to the first collector lens 1a, and it has incidence surface 11b and exiting surface 12b.Each pointolite radiation emitted shape light of forming light source all forms a light beam behind first collector lens 1a arrangement optically focused; Because the maximum caliber D2 of the second collector lens 1b greater than the maximum caliber D1 of the first collector lens 1a (promptly; The maximum caliber D2 of collector lens in light ray propagation direction the place ahead that is positioned at optical axis X is greater than the maximum caliber D1 of the collector lens at the light ray propagation direction rear that is positioned at optical axis X); Then become big via the light beam illuminating area after the second collector lens 1b arrangement; Form bigger light beam, thereby change the light beam form, so that carry out follow-up light arrangement.
In sum, beneficial effect of the present invention is: because the indent degree of incidence surface is less, to assemble the light that is reflected through incidence surface, also reduce the influence to spotlight effect simultaneously, to improve the optically focused reliability.Because the evagination degree of exiting surface is bigger,, improve spotlight effect to shorten the light focusing distance.In addition, because the side can be parallel to optical axis, can reduce light like this and reflect the optical loss that the solid transparent body is caused via the side.
The above only is a preferred embodiments of the present invention, so all equivalences of doing according to the described structure of claim of the present invention, characteristic and principle change or modify, includes in patented claim protection domain of the present invention.
