LED Driver Toggle Sequence Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting fixtures and devices, particularly dimmable LED sources, are underutilized due to the lack of effective control mechanisms, as they often require separate and costly dimmer or control devices for adjusting characteristics like dim level and color temperature, which are not efficiently integrated with the existing wired lighting infrastructure.
Innovation Solution
Incorporating a controller in an LED driver that detects toggle sequences of a light switch to match specific operation modes, allowing for adjustments in dim level, correlated color temperature, and other settings without the need for additional control devices or complex wiring, thereby utilizing existing infrastructure for control and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate dimmer or control devices are used to adjust lighting characteristics, then lighting control functionality is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent combines the control functionality into the existing light switch device itself, merging the control function with the power switching function. The LED driver integrates a controller that detects switch toggle patterns to determine lighting modes, eliminating the need for separate dimmer or control devices while maintaining full lighting control capabilities.
Solution Approach 2:
The light switch is designed to perform multiple functions: basic on/off control and lighting mode selection. By detecting different toggle sequences (single toggle vs. multiple toggles within a time window), the same switch controls both power delivery and lighting characteristics, making the control system universal and eliminating the need for additional specialized control devices.
2Adaptability or versatility
If separate dimmer or control devices are used to adjust lighting characteristics, then lighting control functionality is improved, but installation cost increases
Solution Approach 1:
The control functionality is merged into the existing light switch and LED driver, eliminating the need to install separate dimmer devices or control systems. This reuse of existing infrastructure significantly reduces installation costs while maintaining full lighting control functionality for dim level and color temperature adjustment.
Solution Approach 2:
The LED driver includes an integrated controller that autonomously detects switch toggle patterns and automatically adjusts lighting characteristics based on the detected pattern. The system serves itself by interpreting switch signals internally, eliminating the need for external control devices and reducing installation complexity and cost.
3Ease of manufacture
If existing wired lighting infrastructure is utilized for control, then installation cost is reduced, but control functionality may be limited
Solution Approach 1:
The system dynamically interprets switch toggle patterns to provide different lighting modes. By detecting the number of toggles and time intervals between them, the controller adapts the lighting output (dim level, color temperature) accordingly, enabling versatile control functionality using only the existing simple on/off switch infrastructure without requiring additional control wiring.
Solution Approach 2:
The system changes lighting parameters (brightness, color temperature) based on detected switch toggle sequences. Different toggle patterns correspond to different parameter settings, allowing the existing wiring infrastructure to support multiple lighting modes and characteristics through intelligent interpretation of switch signals rather than requiring separate control lines for each parameter.

AI summary
An LED driver includes a controller configured to detect toggles of a switch that controls whether electrical power is provided to the LED driver. The controller is further configured to determine whether a toggle sequence of the switch matches an operation mode sequence. The toggle sequence of the switch includes a sequence of one or more toggles of the toggles of the switch that the controller detects. The controller is also configured to change a setting of the LED driver based on whether the toggle sequence of the switch matches the operation mode sequence.
