This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,731.

Summary of the Inventive Concept

An innovative system that dynamically adjusts light parameters to optimize melatonin secretion and improve sleep quality, enhancing overall well-being.

Background and Problem Solved

The original patent disclosed a light adjustment method and terminal, but it had limitations in terms of user profiling, real-time light parameter adjustment, and ipRGC stimulation control. The new inventive concept addresses these limitations by introducing advanced user profiling, real-time light parameter adjustment, and ipRGC stimulation control to optimize melatonin secretion and improve sleep quality.

Detailed Description of the Inventive Concept

The new inventive concept comprises a user profile analyzer, a time period detector, and a light adjustment module. The user profile analyzer determines the user's sleep and awake time periods, while the time period detector detects the user's current time period. The light adjustment module adjusts light parameters, including intensity and wavelength, based on the user's profile and time periods to optimize melatonin secretion. The system can also analyze user behavior and preferences to further refine light parameter adjustments.

Novelty and Inventive Step

The new claims introduce the concept of advanced user profiling, real-time light parameter adjustment, and ipRGC stimulation control, which are not present in the original patent. These features enable the system to dynamically adjust light parameters to optimize melatonin secretion and improve sleep quality, providing a significant improvement over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of machine learning algorithms to refine user profiling, integration with wearable devices or health apps to gather user data, or the development of a cloud-based light adjustment system for widespread implementation.

Potential Commercial Applications and Market

The intelligent light adjustment system has significant commercial potential in the healthcare, wellness, and technology industries. It could be integrated into smart home systems, wearable devices, or health apps, providing a unique value proposition for consumers seeking to improve their sleep quality and overall well-being.
