titleOfInvention | Method for designing free-form surface optical element for point light source distribution |
abstract | The invention discloses a method for designing a free-form surface optical element for point light source distribution and belongs to the technical field of non-imaging optics. The method comprises the following steps of: setting a specific structure of the free-form surface optical element according to the design requirements, and designing a free-form surface which meets the preset illumination requirements according to the refraction law and the energy conservation in a computer-assisted mode, so that emergent light of a light source is deflected through the free-form surface and generates preset illumination light spots in a target illumination area, such as circular illumination light spots with ZJU words and uniform rectangular illumination light spots. A certain surface of the free-form surface optical element is a free-form surface, and the free-form surface is obtained through a surface fitting discrete point. The method has the high design efficiency, can realize the complicated illumination and can obtain a continuous free-form surface, and the surface can be machined; and moreover, refractive and reflective free-form surface optical elements can be realized by means of an injection molding technology by using materials such as optical resins. |
