Solution Overview

Problem

LED-based blinders struggle to mimic the fade-in and fade-out behavior and color curve of conventional halogen illuminants while achieving high illumination power, as they often require unnecessary green and blue LEDs that occupy space and reduce overall power.

Innovation Solution

An LED module using a combination of warm white, amber, and red LEDs, with a high proportion of warm white LEDs, optimally distributed on the circuit board to achieve high illumination power and mimic the color decay behavior of halogen illuminants, eliminating the need for green and blue LEDs for color decay modeling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If green and blue LEDs are included to model color decay behavior, then color decay modeling capability is improved, but total illumination power decreases due to space occupation on circuit board

Engineering Contradiction:
Improvecolor decay modeling capabilityVSAvoidtotal illumination power
Core Design Contradiction:
Adaptability or versatilityVSPower

Solution Approach 1:

The patent extracts and removes green and blue LEDs from the circuit board, recognizing that these colors are rarely used in actual blinder applications. This extraction frees up valuable circuit board space that can then be utilized for additional warm white, amber, or red LEDs, thereby increasing total illumination power while retaining color decay modeling capability through the remaining red and amber LEDs.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality by optimizing the color distribution across the circuit board based on actual usage requirements. Instead of uniformly distributing all LED colors, the design concentrates warm white, amber, and red LEDs in proportions that match typical blinder applications, where warm white provides main illumination, amber contributes to color decay modeling, and red provides accent color. This localized optimization ensures both high illumination power and adequate color decay modeling.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If PWM modulation is used to mimic fade-in and fade-out behavior, then temporal behavior emulation is improved, but rapid response behavior of LEDs remains which is not typical for professional blinders

Engineering Contradiction:
Improvetemporal behavior emulationVSAvoidresponse speed
Core Design Contradiction:
Adaptability or versatilityVSSpeed

Solution Approach 1:

The patent applies periodic action through PWM (Pulse Width Modulation) to control the LED illuminants. By switching LEDs on and off at high frequencies with varying duty cycles, the system creates artificial fade-in and fade-out curves that mimic the temporal behavior of conventional halogen blinders. This periodic switching allows the LEDs to emulate the characteristic temporal response of traditional lighting while maintaining LED efficiency and longevity.

Inventive Principle:
Principle #19Periodic action

3Power

If more LEDs are placed on circuit board to increase illumination power, then total illumination power is improved, but circuit board space is limited

Engineering Contradiction:
Improvetotal illumination powerVSAvoidcircuit board area
Core Design Contradiction:
PowerVSArea of stationary object

Solution Approach 1:

The patent extracts unnecessary green and blue LEDs from the circuit board design, as these colors are rarely used in professional blinder applications. This removal of redundant components frees up significant circuit board real estate, allowing for the installation of additional warm white, amber, or red LEDs that directly contribute to illumination power and color decay modeling, thereby increasing total output without expanding the physical footprint.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies multi-functionality by selecting LED colors that serve multiple purposes simultaneously. Warm white LEDs provide both main illumination and contribute to color decay modeling, amber LEDs serve dual roles in color rendering and decay simulation, and red LEDs provide both accent color and temporal behavior modeling. This multi-functional approach maximizes the utility of each LED placed on the circuit board, achieving high illumination power with efficient space utilization.

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