Abstract
The invention relates to a hollow lens being able to focus the parallel light. The ladder type column removed from the convex lens with its one surface being a plane forms the hollow lens capable of focusing the parallel light.
Description
The invention belongs to the new method that the optical element convex lens focus on directional light.
Be focus though existing convex lens can gather directional light, its materials are many, weight greatly, is particularly made large-scale convex lens, and as collecting the convex lens of sunshine diameter more than 1 meter, the shortcoming that its materials are many, weight is big is more outstanding.Though existing Fresnel lens is thin and light, the weak effect of collecting directional light can not gather and is good focus.
In order to overcome the above-mentioned shortcoming of existing convex lens, Fresnel lens, invent the hollow lens of few, the in light weight and focusing effect of a kind of materials with convex lens, can promote the well-being of mankind for focus collection luminous energy directional light such as sunshine are poly-.
The present invention is achieved in that
Its design, making principle are the convex lens on plane with one side, and material also together.
Figure of description is the optical principle synoptic diagram.
Make hollow lens (1) with transparent material, it is different from one side is that the key of the convex lens on plane is to have removed the ladder post therein to form hollow.The vertical directive hollow lens (1) of directional light (2) focuses on directional light (2) with the refraction law of convex lens.
This hollow lens not only materials is few, and is in light weight, and focusing effect is better than Fresnel lens and still can be focus with directional light is poly-with convex lens.
Claims (1)
- A kind of hollow lens is characterized in that: with one side be remove the ladder post in the convex lens on plane after, the hollow lens that directional light can be focused on still.
