Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current human centric lighting devices are inflexible and bulky, as they either meet only one lighting demand or integrate two devices into a single lamp, resulting in a large volume, failing to effectively adjust color temperatures for different needs throughout the day.
Innovation Solution
An LED human centric lighting device with a substrate, multiple blue light chipsets of different color temperatures, an LED light emitting chipset, and a control circuit, where each blue light chipset forms a color temperature light emitting area separated by an enclosure, allowing for independent control and adjustment of color temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple individual lighting devices with different color temperatures are used to meet various lighting demands, then lighting flexibility and adaptability are improved, but device volume and complexity increase
Solution Approach 1:
The patent combines multiple LED light emitting chipsets with different color temperatures (first color temperature and second color temperature) into a single integrated lighting device. The first light emitting area and second light emitting area are arranged on the same substrate, allowing the device to provide multiple color temperature options while maintaining a compact form factor, thus resolving the contradiction between lighting flexibility and device volume.
Solution Approach 2:
The lighting device is designed with multi-functionality by incorporating both first and second LED light emitting chipsets that can emit different color temperatures. The control circuit enables the device to selectively activate different light emitting areas or combine them, providing universal applicability for various lighting scenarios (work/study and relaxation) within a single device, thereby improving adaptability without increasing volume.
2Adaptability or versatility
If a single lighting device integrates multiple color temperature functions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the lighting device into distinct functional modules: first LED light emitting chipset, second LED light emitting chipset, and control circuit, all arranged on a common substrate. Each light emitting area is independently controllable, allowing simplified management of different color temperature functions. This modular segmentation reduces overall device complexity while maintaining adaptability.
Solution Approach 2:
The control circuit serves as an intermediary that manages the complexity of coordinating multiple LED chipsets with different color temperatures. By centralizing the control logic in a dedicated circuit, the system simplifies the interaction between multiple light emitting areas, enabling flexible color temperature adjustment without proportionally increasing overall device complexity.
