Abstract
The invention relates to the field of a lighting lamp, in particular to a combined lens and a lamp using the lens. The combined lens is composed of a plurality of convex lenses, wherein the convex lenses are positioned on the same plane and are respectively provided with focal points which are independent mutually; and the focal points are distributed on at least one plane parallel to the combined lens. The lamp using the combined lens is composed of a combined lens, a plurality of point mode luminophors, a power input device and a housing. The combined lens and the lamp using the lens can increase the light intensity of a single point mode light source to 2-4 times, and the light spots of optical lines generated by the point mode luminophors are overlapped together so as to further increase the brightness of the whole light spots. When three or more than three point mode luminophors and the combined lens are used, the brightness of the whole light spots is increased to 4-6 times than the brightness without lenses. The convex lenses can be normal lenses and also can be screw lenses capable of achieving the photospot principle, namely a Fresnel lens.
