Abstract
The invention provides a Fresnel lens system with position adjustable focuses, which is capable of changing the focus positions of Fresnel lens after condensation effectively, so as to satisfy the requirement of Fresnel lens condensation and high light intensity in engineering practice. A concave mirror is arranged behind each Fresnel lens and the focus thereof, the reflection and condensation of the concave mirror change the light ray direction of the Fresnel lens after condensation, so as to enable the focus position of the Fresnel lens after condensation to be changed. The change of the position and angle of the concave mirror causes corresponding change of the position of the focus, so as to satisfy the requirements of different occasion engineering. The Fresnel lens system provided by the invention effectively solves the problem that the conventional Fresnel lens focus is constant, which causes inconvenience to certain application occasions and even cause low efficiency or waste, so as to effectively improve the exploitation and utilization effects of solar energy.
Description
Technical field
The present invention relates to a kind of focal position adjustable Fresnel Lenses system, can change the focal position behind the Fresnel Lenses optically focused, to satisfy the requirement of using Fresnel Lenses optically focused and focusing position in the engineering.
Background technology
Fresnel Lenses is widely used in photovoltaic, the photo-thermal system, yet the focus of existing Fresnel Lenses is changeless, this makes troubles for some application scenario even causes inefficiency or waste, has influenced effective exploitation of sun power and takes full advantage of.Develop a kind of focal position adjustable Fresnel Lenses system to solve this type of problem, to satisfy various engineering practice needs for this reason.
Summary of the invention
The objective of the invention is to immobilize for the focus that solves existing existing Fresnel Lenses, make troubles for some application scenario even cause inefficiency or waste, influence is to effective exploitation of sun power and the problem that takes full advantage of.
The present invention relates to a kind of focal position adjustable Fresnel Lenses system, can change the focal position behind the Fresnel Lenses optically focused, to satisfy the various requirement that uses Fresnel Lenses optically focused and focusing position in the engineering.
Between Fresnel Lenses and its focus, concave mirror is set, because the reflecting condensation of concave mirror, changed the radiation direction behind the Fresnel Lenses optically focused, focal position behind the Fresnel Lenses optically focused is changed, change position and the angle of concave mirror, the focal position is corresponding change also, to satisfy the requirement of engineering of different occasions.
The invention has the beneficial effects as follows:
Can change or regulate the focal position behind the Fresnel Lenses optically focused, to satisfy the various requirement that uses Fresnel Lenses optically focused and focusing position in the engineering, effectively improve the development and utilization effect to sun power.
Description of drawings
Fig. 1 represents first kind of embodiment of the present invention, the synoptic diagram that the concave mirror main shaft overlaps with normal.
Fig. 2 represents second kind of embodiment concave mirror main shaft off-normal of the present invention, the synoptic diagram that concave mirror main shaft and normal do not overlap.
Embodiment
Embodiment one:
As shown in Figure 1, the adjustable Fresnel Lenses in focal position of the present invention system comprises Fresnel Lenses 1, normal 2, and former focus 3 also comprises concave mirror 4, the focus 5 of the secondary focusing on the normal, concave mirror main shaft 6; Concave mirror 4 places former focus 3 belows, light shines concave mirror 4 through after the former focus 3, concave mirror main shaft 6 overlaps with normal 2, directional light is along the direction that is parallel to normal 2, after Fresnel Lenses 1 top vertical incidence, because the reflecting condensation of concave mirror 4 makes process Fresnel Lenses 1 former focus 3 light afterwards be focused into the focus 5 of the secondary focusing on the normal on the normal 2 again.
Embodiment two:
As shown in Figure 1, the adjustable Fresnel Lenses in focal position of the present invention system, when concave mirror 4 and concave mirror main shaft 6 moved along normal 2, the focus 5 after the secondary focusing on the normal was also mobile at normal 2.
Embodiment three:
As shown in Figure 2, the adjustable Fresnel Lenses in focal position of the present invention system also comprises the focus 7 of the secondary focusing of off-normal; When concave mirror main shaft 6 off-normal 2, because the reflecting condensation of concave mirror 4, light after the feasible process Fresnel Lenses 1 former focus 3 is focused to the focus 7 into the secondary focusing of off-normal again, and the concrete side-play amount of focus 7 off-normal 2 of the secondary focusing of off-normal is relevant with the angle of concave mirror main shaft 6 off-normal 2.
Focal position of the present invention adjustable Fresnel Lenses system adopts the focal position after the simple and cheap concave mirror of cost has changed Fresnel Lenses optically focused, can satisfy the requirement of engineering of different occasions, effectively improve the development and utilization effect to sun power, expand the application space of sun power.
