Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human-centric lighting systems fail to fully consider individual biological rhythms and user-specific characteristics, leading to suboptimal lighting designs that do not meet stringent standards.
Innovation Solution
A method and system for designing human-centric lighting that incorporates use-related information, such as user conditions and physiological characteristics, into the design process. This involves searching historical lighting solutions, selecting appropriate lighting devices, simulating installations, calculating lighting data, and ensuring compliance with applicable standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If formal methods are used to design lighting based on system characteristics, then the design process becomes more structured, but the individual biological rhythm and user-specific characteristics are not fully considered
Solution Approach 1:
The patent applies local quality by transitioning from generic system characteristics to specific user-based parameters. The lighting design incorporates individual biological rhythm parameters (such as melatonin secretion patterns) and user-specific characteristics (age, lifestyle, circadian type) to create customized lighting schedules for each user, thereby maintaining structured design while significantly improving adaptability to individual needs.
2Adaptability or versatility
If multiple HCL standards are incorporated into designs, then the lighting design becomes more comprehensive, but the design time and energy consumption increase significantly
Solution Approach 1:
The patent implements preliminary action by pre-establishing a comprehensive database containing multiple HCL standards (CIE, UL, WELL, CEN, DIN) and their required parameters before the actual design process. The system automatically retrieves and applies relevant standards based on the project requirements, eliminating the need for designers to manually search, interpret, and cross-reference multiple standards, thus significantly reducing design time while maintaining comprehensive compliance.
Solution Approach 2:
The patent introduces an intermediary system (automated lighting design software) that mediates between the designer and the complex HCL standards. This intermediary automatically handles the tedious tasks of standard retrieval, parameter calculation, and compliance verification, allowing designers to focus on creative aspects while ensuring all standards are met without significant time investment.
3Manufacturing precision
If professional designers manually complete HCL designs, then the design quality is higher, but semi-professional lighting professionals cannot complete the designs
Solution Approach 1:
The patent applies self-service by enabling the lighting design system to automatically perform complex calculations, standard compliance checks, and lighting schedule generation without requiring manual intervention from highly skilled professionals. The system self-adjusts parameters based on input data (user characteristics, space geometry, selected standards) and produces compliant designs autonomously, making high-quality HCL design accessible to semi-professionals and even end-users with minimal expertise.

AI summary
A method for designing human-centric lighting (HCL) for illuminating a space is provided. The method includes: providing use-related information to a floor plan of the space; performing a search in a database of historical lighting solutions based on the floor plan to find a lighting solution matching the space; extracting a layout method from the lighting solution matching the space; performing a search in a lighting device database; selecting a lighting device available for the space and layout from the lighting devices; simulating an installation of the lighting device into the space based on the layout; calculating lighting data; performing a search in a lighting standard database; checking whether the calculated lighting data meets an applicable lighting standard; and generating an HCL lighting plan if a result of the checking shows a conformity of the calculated lighting data to the applicable lighting standard.
