Innovation Solution
A system utilizing a buck-boost-device connected to a primary group of light-emitting devices to provide a constant current and voltage to both primary and secondary groups, eliminating the need for additional constant voltage regulators by leveraging the voltage drop across the primary group, and using buck-devices to supply constant currents to each group efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a constant voltage regulator and separate constant current drivers are used for different LED groups, then stable operation and constant voltage are achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the constant voltage regulation function and constant current driving function into a single integrated circuit. This integrated circuit simultaneously provides both voltage regulation and current control for LED groups, eliminating the need for separate constant voltage regulators and multiple constant current drivers, thereby reducing device complexity while maintaining stable operation
Solution Approach 2:
The integrated circuit performs multiple functions: it acts as both a constant voltage regulator and a constant current driver for different LED groups. This multi-functional design allows a single device to replace what would traditionally require multiple separate components, reducing overall system complexity while ensuring reliable and stable LED operation
2Adaptability or versatility
If separate constant current drivers are provided for different LED groups with different current requirements, then proper current supply to each group is achieved, but device complexity increases
Solution Approach 1:
The integrated circuit incorporates dynamic control capabilities that allow it to automatically adjust current supply parameters based on the specific requirements of different LED groups. Through dynamic regulation mechanisms, the single integrated circuit can provide different constant currents to different LED groups as needed, eliminating the requirement for multiple separate constant current drivers while maintaining proper current supply to each group
3Reliability
If additional constant voltage regulators are added to supply buck devices, then constant voltage operation is ensured, but cost and component quantity increase
Solution Approach 1:
The patent merges the constant voltage regulation function into the single integrated circuit that also serves as the constant current driver. This integration eliminates the need for separate constant voltage regulators that would traditionally be added to supply buck devices, reducing the total number of components while ensuring constant voltage operation through the integrated regulation mechanism
