Solution Overview
Problem
Existing circadian lighting systems struggle to effectively implement dynamic and responsive lighting solutions in diverse home automation systems, as they often fail to account for varying lighting device capabilities and outdoor environmental conditions, leading to unnatural lighting effects and reduced user experience.
Innovation Solution
An architecture that utilizes outdoor sensors to capture current intensity and color temperature data, dynamically adjusting circadian lighting curves based on outdoor conditions, and translates these adjustments into compatible commands for diverse lighting devices through a dynamic color manager process, ensuring responsive and natural lighting simulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If circadian lighting is implemented on only a portion of lighting devices, then implementation cost is reduced, but the benefit of circadian lighting is greatly reduced
Solution Approach 1:
The system introduces a bridge device that acts as an intermediary between the controller and existing lighting devices. This bridge device includes a controllable light source that can be precisely controlled for circadian lighting, while also having the capability to control legacy lighting devices through various protocols (0-10V, DALI, PWM, phase-cut). This intermediary approach allows the system to achieve full circadian lighting benefits without requiring replacement of all existing lighting devices, thus resolving the contradiction between implementation cost and lighting benefit.
2Adaptability or versatility
If outdoor sensors are added to dynamically adjust lighting, then responsiveness to environmental conditions is improved, but device complexity increases
Solution Approach 1:
The bridge device is designed with multi-functionality, serving as both a controllable light source for circadian lighting and a controller for legacy lighting devices. It can receive and process various control protocols (0-10V, DALI, PWM, phase-cut) and convert them to appropriate control signals. This universal design allows the system to add environmental sensing and dynamic adjustment capabilities without proportionally increasing overall system complexity, as the bridge device consolidates multiple functions in a single component.
