Problems solved by technology

[0007] In the above-mentioned technical solution, first of all, it is necessary to clarify the customer's needs, and to know what kind of lighting equipment the customer wants, and then import the design parameters obtained from the user into the pre-trained deep learning network model, and the deep learning The network model outputs the corresponding surface point set. The surface point set describes the shape of the lens to be processed, and then fits the surface point set that cannot be recognized by the processing equipment into the data structure of the surface equation that the processing equipment can recognize, and then uses The surface equation is used to process the lens, thus completing the entire automated process from lens design to processing, reducing the uncertainty of manual design, and further improving the lower limit of the design level, increasing the accuracy of customer expectations, It overcomes the technical problems of too many uncontrollable factors involving people, too much design difficulty and too much calculation in the traditional field of lens design

Description

technical field [0001] The present invention relates to the field of lighting system design, in particular to a lighting system design method based on deep learning. Background technique [0002] Lighting system design is an important branch of optical design, which can solve various needs in life and industry through lighting design. The existing lighting optical system is mainly completed with the assistance of lighting design software such as LightTools. In LightTools and other lighting design software, through system construction and evaluation function writing, a lighting system close to the initial requirements is finally optimized. However, this design method is limited by the selection of the initial structure. If the initial structure is selected reasonably, the design difficulty will be greatly reduced and the optimization time will be reduced. Otherwise, the difficulty of optimization and design will be increased. At the same time, the design of the optical syste...
