Alternating LED Row Circuit Board for Dynamic Color Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lighting devices that utilize LEDs are expensive to stock and produce due to the need for multiple devices designed for different light colors, and they lack the ability to easily switch or mix light colors as desired, especially for applications requiring dynamic color changes throughout the day.
Innovation Solution
A lighting device equipped with at least two LED groups, each emitting a different light color, where the LED groups can be controlled independently to mix light colors continuously, allowing for the adjustment of white light colors between 3,000K and 6,500K and the inclusion of colored lights, using a circuit board with separate line arrangements and connections for each group, enabling separate control and pulse-width modulation for efficient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lighting devices are stocked for different light colors, then different light color requirements can be met, but production and stocking costs increase
Solution Approach 1:
The patent implements multi-functionality by integrating multiple LED groups with different light colors (warm white, neutral white, daylight white, and colored LEDs) into a single lighting device. The control unit enables this universal device to adapt to different lighting requirements by selectively activating specific LED groups, eliminating the need to stock multiple separate devices for different applications.
Solution Approach 2:
The lighting device is segmented into multiple independent LED groups, each responsible for a specific light color. The control unit divides the control signals to selectively activate individual LED groups based on the desired lighting effect, allowing flexible combination of different light colors within a single device structure.
2Adaptability or versatility
If lighting devices are produced based on specific customer needs, then customization is achieved, but production time increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple LED groups with different light colors and their corresponding control circuits into the lighting device during mass production. This preliminary setup enables rapid customization at the user level through simple control signal adjustments, without requiring time-consuming reconfiguration or reassembly during actual product customization.
3Adaptability or versatility
If a single lighting device emits multiple light colors, then versatility improves, but control complexity increases
Solution Approach 1:
The patent merges multiple LED groups with different light colors into a single integrated lighting device with a unified control unit. The control unit consolidates the control signals for all LED groups, managing them through a single interface rather than requiring separate control circuits for each LED group, thereby reducing overall control complexity while maintaining versatility.
