Multicolor Lamp Mode Indicator for Clear Timing Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power converters for LED lamp strings cannot effectively differentiate between multiple timing modes using a single-function timing indicator lamp, leading to user confusion regarding the active mode.
Innovation Solution
A multicolor light-emitting indicator lamp is integrated into the power converter, which emits distinct colors to indicate different work modes, including standby, lighting, and various timing modes, allowing users to determine the current mode through color differentiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-function timing indicator lamp is used, then the device complexity is reduced, but the ability to differentiate between multiple timing modes deteriorates
Solution Approach 1:
The patent applies color changes by using a multicolor light-emitting indicator lamp that can emit different colors (e.g., red, green, blue) to represent different timing modes. This allows the single indicator lamp to convey multiple pieces of information simultaneously, resolving the contradiction between device simplicity and information differentiation.
Solution Approach 2:
The indicator lamp is designed to perform multiple functions: indicating timing mode, showing operational status, and providing user feedback. By making the indicator lamp universal rather than single-function, the patent maintains device simplicity while enabling comprehensive mode differentiation through color coding.
2Loss of information
If a multicolor light-emitting indicator lamp is used, then the ability to differentiate between work modes is improved, but the device complexity increases
Solution Approach 1:
The patent utilizes color changes as the primary mechanism for mode differentiation. The multicolor indicator lamp emits distinct colors corresponding to different work modes (standby, timing mode 1, timing mode 2, etc.), providing clear visual feedback without requiring additional indicator components.
Solution Approach 2:
The patent changes the operational parameters of the indicator lamp by controlling its emission color through PWM (Pulse Width Modulation) signals. The controller adjusts the duty cycle of different color channels to produce the desired color output, enabling flexible mode indication without hardware complexity.
3Ease of operation
If multiple indicator lamps are used to indicate different modes, then the clarity of mode indication is improved, but the device complexity and cost increase
Solution Approach 1:
The patent merges multiple indicator functions into a single multicolor light-emitting component. Instead of using separate indicator lamps for different modes, the system combines red, green, and blue LED elements within one indicator housing, controlled by a single controller, achieving clear mode indication with reduced complexity.
Solution Approach 2:
The single multicolor indicator lamp serves as a universal indicator for all operational modes. By designing the indicator to be multi-functional rather than having dedicated indicators for each mode, the patent reduces the total number of components while maintaining clear mode differentiation.
