In some embodiments, the distance of the first optically focused group and the second optically focused group is 60 ~ 160mm.Thus, dispersing and converging of light is between the two convenient to.Thus, that disperses after the light that the first optically focused group can be facilitated to converge converges impinges upon in the second optically focused group again, the object that the light collection degree that satisfied second optically focused group sends is high.
In some embodiments, first optically focused group comprises the first convex lens and the second convex lens, the side of the first convex lens and the second convex lens is plane, and opposite side is convex surface, and the distance between the convex surface of the first convex lens and the convex surface of the second convex lens is 0.4 ~ 0.6mm.Thus, the light that light source sends acts directly on the second convex lens after the first convex lens converge, thus obtains the light of convergence degree, the light that light source sends effectively can be converged, and improves intensity and the brightness of the light emitted.
In some embodiments, the distance of light source and the first optically focused group and light source is 0 ~ 20mm, and the first convex lens are identical with the structure of the second convex lens, and the diameter of the convex surface of the first convex lens is 9 ~ 25mm.Thus, ensure that the first optically focused group can the light that sends of in-plant collection light source, and can disperse again within the scope of shell after the convergence effect of the second convex lens, be convenient to the second optically focused group and light is converged.
In some embodiments, the second optically focused group comprises plane concavees lens and the 3rd convex lens, and plane concavees lens and the 3rd convex lens are that object lens glue together part, and the diameter of the 3rd convex lens is 28 ~ 100mm.Thus, the light after the first optically focused group converges by the second optically focused group, and can better obtain positive circular light spot, light range is far away.
In some embodiments, the focal length F of object lens gummed part is 75.21 ~ 79.21mm.Thus, the light that the second optically focused group effectively can receive the first optically focused group place and obtains can be ensured.
In some embodiments, the distance between light source and the first optically focused group is 14 ~ 14.3mm.Thus the light making light source send can realize effectively converging in the first optically focused group.
Accompanying drawing explanation
