The distance between each focus is 1mm-50mm.Because of light-emitting surface 11 and the incidence of the combined type optical lens 10
Face 12 integrally seamlessly transits, even if the thickness between that is, each light-emitting surface domain is variant, but will not be particularly evident, therefore
The focal position of the combined type optical lens 10 can more concentrate, distance between the corresponding focus of the light of different illumination regions
It can be closer；It is provided in the present embodiment and can guarantee that illuminator structure is more compact, and do not influence the combined type optical lens
The optimum value range of distance between the different focal point of 10 practical application effect of mirror.
The present invention proposes a kind of combined type optical lens 10 with a variety of focal lengths, by going out with a variety of different focal lengths
Smooth surface domain is fused into an entirety, and the light-emitting surface 11 of the combined type optical lens 10 is complete class spherical structure, the plane of incidence
12 are also fused into complete plane face domain；After different light is projected in the focus of corresponding position, the combination can passed through
It is overlapped or separates after formula optical lens 10 and be irradiated to setting regions, so that applying the photograph of the combined type optical lens 10
While bright device has different illumination region handoff functionalities, it is also ensured that the structure of lighting device is simpler compact, this
Outside, since the light-emitting surface 11 and the plane of incidence 12 of the combined type optical lens 10 are overall structure, do not splice gap, light exists
Will not occur illumination edge blurry when superposition because of multiple reflections, be not between the light in different light-emitting surface domains interference and
Serious phenomenon is lost, the utilization rate and illuminating effect of light are substantially increased.
The technical principle of the invention is described above in combination with a specific embodiment.These descriptions are intended merely to explain of the invention
Principle, and shall not be construed in any way as a limitation of the scope of protection of the invention.Based on the explanation herein, the technology of this field
Personnel can associate with other specific embodiments of the invention without creative labor, these modes are fallen within
Within protection scope of the present invention.
