Problems solved by technology

However, this kind of light distribution design scheme needs to use multiple softwares to operate together, which will increase the complexity of the design to a certain extent
[0003] In particular, when performing feedback optimization of the extended light source lighting system, the surface data needs to be continuously transferred in the three softwares, and the manual transfer of the traditional method greatly limits the freedom of design
Moreover, we can also find that it will be more cumbersome to construct a non-rotationally symmetrical mechanical model in modeling software, and the designer's work efficiency will drop sharply when iterative optimization

Abstract

The invention discloses a method for quickly establishing a non-rotational symmetry lighting system model. The method comprises the steps of first utilizing a grid energy division principle to calculate point cloud data on the surface of a lighting system; establishing a channel between numerical analysis software Matlab and lighting simulation software TracePro through dynamic data exchange (DDE) communication, and transmitting the point cloud data to the TracePro; finally performing fitting on data points through TracePro macro languages, and utilizing sectioning to quickly form a solid model. The method has very high convenience and program ductility, the lighting system model designed according to the method can be generated automatically and quickly, and automatic optimization can be performed when a program module with respect to extension of iteration feedback of a light source lighting system is added.

Description

technical field [0001] The invention belongs to the field of non-imaging illumination, and in particular relates to a method for rapidly establishing an illumination system model based on an LED light source. Background technique [0002] At present, three steps are generally required for secondary optical light distribution design: Step 1, after constructing the mapping relationship between the light source and the target surface, calculate the numerical solution of the surface of the lighting system through numerical analysis software (such as Matlab). Step 2, import the numerical solution obtained in step 1 into a 3D modeling software (such as SolidWorks) to establish a solid model. Step 3, import the solid model into lighting simulation software (such as TracePro) for simulation analysis. However, this type of light distribution design scheme requires the use of multiple softwares for collaborative operation, which will increase the complexity of the design to a certain...
