Solution Overview

Problem

Existing LED lighting systems require separate dimming circuits for brightness and color temperature adjustment, leading to high installation costs and space requirements, as well as the need for external dimming signals and additional wiring.

Innovation Solution

An integrated dimming and color panel power supply with a control panel featuring built-in brightness and color temperature control mechanisms, allowing direct installation on walls or cabinets without external dimming signals, and integrating the dimming and color power supply module within the housing, eliminating the need for separate installation space and wiring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If external dimming signals and separate dimming circuits are used for brightness and color temperature adjustment, then the lighting control function is achieved, but the installation cost and device complexity increase

Engineering Contradiction:

Improvelighting control functionVSAvoidinstallation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines brightness control and color temperature control into a single integrated power supply unit. The control panel integrates both dimming functions, and the power supply module contains both brightness dimming circuit and color temperature dimming circuit, eliminating the need for separate external dimming devices and reducing installation complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The power supply module is designed to perform multiple functions simultaneously - it provides power supply, brightness dimming, and color temperature dimming all in one unit. This multi-functional design replaces the need for separate power supply and dimming devices, reducing the overall system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If external dimming signals and separate dimming circuits are used, then the lighting control function is achieved, but the installation cost increases

Engineering Contradiction:

Improvelighting control functionVSAvoidinstallation cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent merges multiple functions (power supply, brightness control, color temperature control) into a single integrated unit, eliminating the need to purchase and install separate external dimming devices, thereby reducing material costs and installation expenses

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the dimming control functions from external separate devices and integrates them directly into the power supply unit, eliminating the need for additional external components and reducing overall system cost

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If separate dimming circuits for brightness and color temperature are used, then the lighting control function is achieved, but additional installation space is required

Engineering Contradiction:

Improvelighting control functionVSAvoidinstallation space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines brightness dimming circuit and color temperature dimming circuit within the same power supply housing. The control panel is also integrated, allowing both control functions to be accessed from a single location, thereby eliminating the need for additional installation space for separate dimming devices

Inventive Principle:

Principle #5Merging (Combining)

4Ease of manufacture

If the dimming and color power supply module is installed separately from the control panel, then the electrical connection is simplified, but the installation space requirement increases

Engineering Contradiction:

Improveelectrical connection easeVSAvoidinstallation space

Core Design Contradiction:

Ease of manufactureVSArea of stationary object

Solution Approach 1:

The patent integrates the dimming and color power supply module with the control panel into a single compact unit. The control panel is mounted on the housing of the power supply module, allowing electrical connections to be made at a single location while minimizing the overall installation footprint

Inventive Principle:

Principle #5Merging (Combining)
