Innovation Solution

An LED lamp system with different color temperatures and operation modes is achieved by using an AC power source, wave generator, driving circuit, microprocessor, and switching circuits to control the illumination of multiple LED lamp sets, allowing for automatic adjustment of light intensity and color based on environmental conditions, enabling intellectual light control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a moving object detection circuit is separated from LED lamps, then the LED lamps can maintain simple structure, but the installation becomes difficult and installation time increases

Engineering Contradiction:
Improvestructure complexityVSAvoidinstallation time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent integrates the moving object detection circuit directly into the LED lamp assembly, combining previously separate components (detection circuit, amplifier, light-sensitive detector, lens set) with the LED lamp structure. This merging eliminates the need for separate installation of detection circuits and reduces installation time while maintaining functional simplicity through integrated design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The LED lamp system is designed to perform multiple functions: illumination, moving object detection, and automatic lighting control. By making the LED lamp universal (capable of both lighting and detection functions), the system eliminates the need for separate detection devices, thereby reducing installation complexity and time while maintaining simple overall structure.

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

2Device complexity

If LED lamps are designed with only moving object detection control, then the detection function is simple, but the functionality is confined and not suitable for various applications

Engineering Contradiction:
Improvecontrol circuit complexityVSAvoidapplication suitability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic control capabilities allowing the LED lamp to switch between different operation modes (manual control, automatic detection control, combination mode) and adjust lighting parameters (brightness, color temperature). This dynamic adaptability enables the simple control circuit to serve various applications by changing operational characteristics rather than requiring complex dedicated circuits for each application.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system utilizes parameter changes in lighting (brightness levels, color temperature adjustment between warm light 2700K-3000K, warm white light 4000K-5500K, and cool white light 5500K-6500K) to adapt to different applications. By varying lighting parameters rather than requiring different hardware configurations, the system achieves versatility across multiple applications while maintaining simple control circuitry.

Inventive Principle:
Principle #35Parameter changes

3Illumination intensity

If three LED lamps with different color temperatures are used to emit lights of three color temperatures, then the color temperature requirements are met, but vast materials and elements are wasted

Engineering Contradiction:
Improvecolor temperature varietyVSAvoidmaterial waste
Core Design Contradiction:
Illumination intensityVSLoss of substance

Solution Approach 1:

The patent combines multiple LED lamp sets with different color temperatures into a single integrated system. Instead of using three separate LED lamps (each requiring complete sets of heat dissipating base, insulated sleeve, LED dies, heat dissipation casing, transparent lampshade, driving power source, detection circuits, etc.), the invention merges them into one unified LED lamp assembly that houses all three color temperature LED modules, thereby dramatically reducing material waste and component redundancy.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single LED lamp system is designed to provide multiple color temperature outputs (warm light, warm white light, cool white light) through integrated LED modules. This multi-functional design eliminates the need for multiple dedicated single-function lamps, reducing material consumption while maintaining the capability to emit various color temperatures as required by different applications.

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

4Illumination intensity

If three LED lamps with different color temperatures are used, then the color temperature requirements are met, but manufacturing time and labors are increased

Engineering Contradiction:

Solution Approach 1:

The patent merges three separate manufacturing processes (each requiring assembly of heat dissipating base, insulated sleeve, LED dies, heat dissipation casing, transparent lampshade, driving power source, detection circuits, etc.) into a single integrated manufacturing process. By producing one unified LED lamp system containing all three color temperature modules, the invention reduces total manufacturing time and labor requirements while maintaining the capability to provide varied color temperatures.

Inventive Principle:
Principle #5Merging (Combining)

5Device complexity

If LED lamps without automatic control are used, then the control is simple, but power saving and environmental protection requirements are not met

Engineering Contradiction:
Improvecontrol system complexityVSAvoidpower consumption
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The patent implements feedback control through light-sensitive detectors that automatically detect ambient light conditions and adjust LED lamp operation accordingly. The detection circuits provide feedback signals to the control system, enabling automatic adjustment of lighting based on environmental conditions. This feedback mechanism achieves power saving and environmental protection goals by eliminating unnecessary lighting when natural light is sufficient, while maintaining relatively simple control system architecture through automated decision-making.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The LED lamp system performs self-service through automatic detection and control functions. The integrated detection circuits and control systems automatically monitor environmental conditions (light levels, moving objects) and adjust lighting operation without requiring manual intervention. This self-service capability achieves power saving objectives by automatically turning off or dimming lights when not needed, reducing energy loss while maintaining simple overall control through automated operations.

Inventive Principle:
Principle #25Self-service
