1Adaptability or versatility

If a remote control is used to control and adjust color temperature, then color temperature adjustment is achieved, but production costs increase and adjustment stability decreases

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The light-emitting module is divided into multiple LED chips with different color temperatures (first, second, and third LED chips with different color temperatures). Each LED chip is independently controllable through separate control signals, allowing the system to achieve multiple color temperature outputs without requiring external remote controls. This segmentation enables direct integration of color temperature adjustment functionality within the light fixture itself.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control module integrates multiple functions into a single unit: it receives control signals, determines target color temperature values, and drives multiple LED chips with different color temperatures. This multi-functional integration eliminates the need for separate remote control devices and achieves both color temperature adjustment and cost reduction through a unified control system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple light-emitting modules with different color temperatures are used, then color temperature adjustability is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple LED chips with different color temperatures are integrated into a single light-emitting module, and the control module combines signal reception, processing, and driving functions. This merging approach allows the system to achieve multiple color temperatures while maintaining a compact structure and avoiding the need for separate control devices for each LED chip.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control module dynamically adjusts the output of different LED chips based on received control signals and target color temperature values. By dynamically controlling the brightness and combination of different color temperature LEDs, the system achieves flexible color temperature adjustment without requiring physical reconfiguration or additional complex hardware.

Inventive Principle:
