Abstract
A Fresnel Lenses system for focus stack, comprises the first Fresnel Lenses (1), and the first focus (3), is characterized in that: the Fresnel Lenses system of this focus stack also comprises the first level crossing (2), the second focus (4); After directional light is by the first Fresnel Lenses (1) top vertical incidence, due to the reflection of the first level crossing (2), making the focus after the first Fresnel Lenses (1) optically focused is the second focus (4); The Fresnel Lenses system of described focus stack also comprises the second Fresnel Lenses (8), the 4th focus (6), the second level crossing (7), the 3rd focus (5); After directional light is by the second Fresnel Lenses (8) top vertical incidence, due to the reflection of the second level crossing (7), making the focus after the second Fresnel Lenses (8) optically focused is the 3rd focus (5).Focal position after adjustable change Fresnel Lenses optically focused, overlaps two or more focus spot or stack, thereby the light intensity of overlap-add region is doubled, and to meet, uses Fresnel Lenses optically focused and the requirement to high light intensity in engineering practice.
Description
The application's request: application number 201310228636.7, on June 9 2013 applying date, denomination of invention is the right of priority of application for a patent for invention of the Fresnel Lenses system of focus stack.
Technical field
The utility model relates to a kind of Fresnel Lenses system of focus stack, by two or more Fresnel Lenses, formed, can change the focal position after each Fresnel Lenses optically focused, two or more focus spot are overlapped or stack, thereby the light intensity of overlap-add region is doubled, to meet, in engineering practice, use Fresnel Lenses optically focused and the requirement to high light intensity.
Background technology
Fresnel Lenses is widely used in photovoltaic, photo-thermal system, yet the focus of existing Fresnel Lenses is changeless, or focus light intensity is limited, this makes troubles and even causes inefficiency or waste to some application scenario, can not meet the requirement of some engineering practice, affected the effective exploitation of sun power and made full use of.Develop a kind of Fresnel Lenses system of focus stack of variable-focus to solve problems for this reason.
Utility model content
The purpose of this utility model is to immobilize for solving the focus of existing Fresnel Lenses, focus light intensity is limited, make troubles to some application scenario and even cause inefficiency or waste, can not meet the requirement of some engineering practice, impact is to the effective exploitation of sun power and the problem making full use of.
The utility model relates to a kind of Fresnel Lenses system of focus stack of variable-focus, comprises the first Fresnel Lenses, the first focus, and the Fresnel Lenses system of this focus stack also comprises the first level crossing, the second focus; After directional light is by the first Fresnel Lenses top vertical incidence, due to the reflection of the first level crossing, making the focus after the first Fresnel Lenses optically focused is the second focus.
Described Fresnel Lenses system also comprises the second Fresnel Lenses, the 4th focus, the second level crossing, the 3rd focus; After directional light is by the second Fresnel Lenses top vertical incidence, due to the reflection of the second level crossing, making the focus after the second Fresnel Lenses optically focused is the 3rd focus.
By regulating the first level crossing and the second level crossing, can make the second focus approach or overlap with the 3rd focus, thereby this region light intensity is increased.
The utility model can change the focal position after Fresnel Lenses optically focused, two or more focus spot is overlapped or stack, thereby the light intensity of overlap-add region is doubled, and to meet, uses Fresnel Lenses optically focused and the requirement to high light intensity in engineering practice.
Between Fresnel Lenses and its focus, level crossing is set, reflection due to level crossing, changed the radiation direction after Fresnel Lenses optically focused, focal position after Fresnel Lenses optically focused is changed, the position and the angle that change level crossing, focal position is corresponding change also, two or more focus spot is overlapped or stack, thereby the light intensity of overlap-add region is doubled, to meet the requirement of engineering of different occasions.
The utility model can change or regulate the focal position after Fresnel Lenses optically focused, two or more focus spot are overlapped or stack, thereby the light intensity of overlap-add region is doubled, to meet the various needs of different occasion focusing light intensity, effectively improve the development and utilization effect to sun power.
