Solution Overview

Problem

Existing LED lamps are limited to fixed brightness, color temperature, and color settings, making it difficult to meet changing demands and can lead to reduced service life due to prolonged high brightness and high color temperature operation.

Innovation Solution

A regulatable LED driver system incorporating a Bluetooth module, dimming circuit, and control module that allows remote adjustment of LED parameters through a control terminal or manual input via a dimming knob, enabling flexible control of brightness, color temperature, and color.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If LED lamps operate at fixed high brightness and high color temperature, then illumination performance is maintained, but service life is reduced

Engineering Contradiction:
ImprovebrightnessVSAvoidservice life
Core Design Contradiction:
Illumination intensityVSDuration of action of stationary object

Solution Approach 1:

The patent implements dynamic adjustment of LED operating parameters including brightness, color temperature, and drive current. The system allows real-time modification of these parameters through control circuits that regulate the LED driver, enabling the LED to operate at optimal conditions rather than fixed high intensity, thereby extending service life while maintaining illumination performance when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes multiple operating parameters of the LED simultaneously including drive current, brightness level, and color temperature. By adjusting these parameters dynamically based on application requirements, the system prevents continuous operation at damaging high levels while ensuring adequate illumination when required, thus resolving the contradiction between maintaining brightness and extending service life.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If LED lamps are switched wholly on or off, then simple control is achieved, but inability to meet changing brightness demands occurs

Engineering Contradiction:
Improvecontrol simplicityVSAvoidbrightness adjustment capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent transitions from static on/off control to dynamic continuous dimming control. The system incorporates dimming circuits and control modules that enable smooth adjustment of brightness levels across a wide range, allowing the LED to adapt to varying illumination requirements while maintaining user-friendly control interfaces.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements multiple control modes including dimming, color temperature adjustment, and various operating modes within a single LED system. This multi-functional approach allows the same LED lamp to serve different application scenarios (reading, ambient lighting, task lighting) without requiring multiple fixed-function lamps, thereby enhancing adaptability while keeping control simple through integrated controls.

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

3Illumination intensity

If LED lamps operate at high color temperature for long periods, then bright white light is provided, but component strain increases

Engineering Contradiction:
Improvewhite light outputVSAvoidcomponent durability
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The patent dynamically adjusts the color temperature parameter of the LED by modifying the drive current and operating conditions. The system can shift between warm white and cool white color temperatures depending on requirements, preventing continuous operation at high color temperature conditions that stress components, while still providing bright white light when needed for tasks requiring high illumination.

Inventive Principle:
Principle #35Parameter changes
