Described first lens 31 comprise a level bottom surface 311, a bending end face 315 and connect the annular side 313 of described bottom surface 311 and end face 315.Wherein, described bottom surface 311 is the plane of a circle; Described side 313 extends to form straight up from the outer perimeters of described bottom surface 311; Described end face 315 is outwards convexly equipped with formation from the top of described side 313 outer rim.
311 centers, described bottom surface are recessed to form a depression 317 along central shaft I-I line towards the direction of described end face 315.Described depression 317 is for accommodating described light-emitting component 20 in the inner, and the inner surface of described depression 317 forms the first incidence surface 3170.Described depression 317 is injected first lens 31 inside after light-emitting component 20 being incident to the divergence of beam on it.In the present embodiment, the inner surface of described depression 317 is a dome concave surface.
Described side 313 and common first exiting surface 3180 that forms of described end face 315.The curvature of described the first exiting surface 3180 is less than the curvature of described the first incidence surface 3170, so that the light that light-emitting component 20 sends carries out dispersing in various degree on the first exiting surface 3180 and the first incidence surface 3170.
Described end face 315 is a free form surface, and it extends inwardly to after identical height obliquely from the top of described side 313 outer peripheral edges, then extends and converge on central shaft I-I line towards the central shaft I-I ' of first lens 31 line under oblique.So, described end face 315 center is recessed to form a groove 319 along the central shaft I-I ' line of first lens 31 towards described bottom surface 311 directions.
Described groove 319 is roughly funnel-form, and it can be by backward its periphery directional divergence of light refraction being incident on it.
Described the second lens 33 are roughly round table-like, and it is about central shaft II-II ' line Central Symmetry.In the present embodiment, described the second lens 33 can be made up of the transparent material such as Merlon, polymethyl methacrylate.
Described the second lens 33 comprise bottom surface 331, the side 333 extending internally obliquely from described bottom surface 331 outer perimeters of a level and the bending end face 335 that connects described side 333.Described the second lens 33 are along reducing gradually towards the direction of end face 335 from bottom surface 331 perpendicular to the diameter of central shaft II-II ' line direction.
331 middle parts, bottom surface of described the second lens 33 are recessed to form a depression 337 towards the direction of described end face 335.The section of described depression 337 is M shape, and described depression 337 is about central shaft II-II ' line symmetry.The volume of described depression 337 is greater than the volume of described first lens 31, and it can be accommodated described first lens 31 in the inner.Meanwhile, the inner surface of described depression 337 forms the second incidence surface 3370.The curvature of described the second incidence surface 3370 is greater than the curvature of described the first exiting surface 3180.
Described depression 337 extends to after identical height towards described end face 335 directions along described bottom surface 331 middle part peripheries, then extends and converge on described central shaft II-II ' line towards described central shaft II-II ' line.
Described peripheral side 333 and common second exiting surface 3380 that forms of described end face 335.The curvature of described the second exiting surface 3380 is less than the curvature 3370 of described the second incidence surface, so that light carries out dispersing in various degree on the second exiting surface 3380 and the second incidence surface 3370.
Width between described side 333 and described depression 337 inner surface correspondingly reduces towards the direction of end face 335 gradually from described bottom surface 331.
Described end face 335 is a free form surface, its from the top of described side 333 outer peripheral edges towards the oblique downward-extension of direction of described central shaft II-II ' and converge on described central shaft II-II ' line.So, described end face 335 center is recessed to form a groove 339 along central shaft II-II ' line towards described bottom surface 331 directions.Width between described end face 335 and the top inner surface of described depression 337 increases gradually towards the direction of described central shaft II-II ' line.
Described groove 319 is roughly funnel-form, and it can be incident to light-emitting component 20 backward its periphery directional divergence of light refraction on it.
Referring again to Fig. 1, when assembling, described light-emitting component 20 is contained in the depression 317 of described first lens 31, and with described depression 317 intervals just to arrange.Described first lens 31 is contained in the depression 337 of described the second lens 33, and arranges with described the second lens 33 intervals.Now, the central shaft II-II ' line of the central shaft I-I ' line of described first lens 31 and described the second lens 33 coincides.So, the central shaft of light-emitting component 20, first lens 31 and the second lens 33 is on same straight line.
Refer to Fig. 4, when described illuminating module 1 is worked, first the light that light-emitting component 20 sends enter the inside of first lens 31, the divergently outgoing after refraction on the first exiting surface 3180 of described first lens 31 again of this part light in the first incidence surface 3170 refractions of described first lens 31.And then, this part light is refracted into the inside of the second lens 33 again via the second incidence surface 3370 of described the second lens 33, and after reflecting via the second exiting surface 3380 of described the second lens 33, more disperses and outgoing equably.
The light sending due to described light-emitting component 20, successively via outgoing after the disperse function of first lens 31 and the second lens 33, makes the lighting angle of whole illuminating module 1 become large.And because the stronger light of described light-emitting component 20 middle part light intensity is also after dual the dispersing of groove 319 and groove 339, it is more even that its intensity also becomes, thereby improved the light effect that of whole illuminating module 1.
