Lighting Device Segmentation for Stable and Flickering Light Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices struggle to simultaneously provide flickering lights at specific frequencies while maintaining the stability and non-flickering advantages of conventional lighting.
Innovation Solution
A lighting device incorporating a light board with both first and second light emitting elements, where a light dimmer circuit drives the first elements to produce non-flickering lights using pure DC current and drives the second elements to produce flickering lights using pulse DC current, with the flicker frequency adjustable within a range perceptible by the human visual system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light emitting elements are controlled to provide flickering lights at a certain frequency, then treatment effects for specific diseases are enhanced, but the stability of emitted light intensity is reduced and visual discomfort increases
Solution Approach 1:
The patent divides the light emitting elements into two distinct groups: first light emitting elements that provide stable non-flickering light, and second light emitting elements that provide flickering light at specific frequencies. This segmentation allows the system to simultaneously achieve both stable illumination and therapeutic flickering effects without compromising overall light intensity stability.
Solution Approach 2:
Different regions of the light board are assigned different functional qualities: the first area contains elements optimized for stable continuous light output, while the second area contains elements configured for controlled flickering output. This local differentiation enables each region to perform its specialized function effectively while contributing to the overall system performance.
2Adaptability or versatility
If light emitting elements are controlled to provide flickering lights at a certain frequency, then therapeutic benefits are achieved, but visual comfort is reduced due to perceptible flicker
Solution Approach 1:
The patent separates the lighting function into two distinct segments: one providing comfortable stable light and another providing therapeutic flickering light. This segmentation ensures that the harmful flicker effect is localized to specific elements while the majority of the lighting output remains stable and comfortable for visual perception.
Solution Approach 2:
The light board incorporates spatially differentiated zones with distinct optical characteristics. The first area provides uniform stable illumination for visual comfort, while the second area provides controlled flickering for therapeutic purposes, allowing each zone to optimize its local function without negatively impacting the other.
3Adaptability or versatility
If a single light board provides both flickering and non-flickering lights, then device versatility is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple lighting functions within a single integrated light board structure. By incorporating both first and second light emitting elements in one device, the system achieves versatile functionality (stable lighting plus therapeutic flickering) while avoiding the need for separate independent lighting devices, thereby managing complexity through integration rather than multiplication of separate systems.
Solution Approach 2:
The light board is designed as a universal device capable of performing multiple functions simultaneously: providing stable ambient illumination through the first light emitting elements and delivering therapeutic flickering light through the second light emitting elements. This multi-functionality is achieved within a single device architecture, enhancing versatility without requiring multiple separate devices.

AI summary
A lighting device includes a light board and a light dimmer circuit. The light board includes multiple first light emitting elements and second light emitting elements. The first light emitting elements are disposed in a first area of the light board. The second light emitting elements are disposed in a second area of the light board. The light dimmer circuit is configured to drive the second light emitting elements to generate flickering lights from the second area of the light board, and is configured to drive the first light emitting elements to generate non-flickering lights from the first area of the light board.
