Discharge Lamp Drive Device Using Machine Learning for Life Extension
Solution Overview
Problem
Existing discharge lamp drive methods fail to adequately account for individual differences between discharge lamps, leading to insufficient extension of lamp life.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed drive method is used for discharge lamps, then the control system is simple, but the lamp life cannot be sufficiently extended due to individual differences between lamps
Solution Approach 1:
The patent implements dynamic drive patterns that adjust voltage and current parameters in real-time based on lamp individual characteristics. The control system transitions from fixed to dynamic control by monitoring lamp voltage and automatically selecting optimal drive patterns from multiple predefined patterns, thereby extending lamp life while managing complexity through automated adaptation.
Solution Approach 2:
The patent applies parameter changes by modifying drive voltage, current, and frequency parameters according to detected lamp characteristics. The control system stores multiple drive patterns with different parameter sets and selects/apples appropriate patterns based on individual lamp voltage measurements, allowing customization of drive parameters to extend lamp life without requiring complete system redesign.
2Duration of action of stationary object
If drive parameters are adjusted to extend lamp life, then lamp life is extended, but the drive power supplied to the lamp must be precisely controlled
Solution Approach 1:
The patent implements feedback control by continuously monitoring lamp voltage and comparing it against target values. The control system uses voltage detection results to automatically select and adjust drive patterns, creating a closed-loop control mechanism that maintains precise power control while extending lamp life through adaptive parameter adjustment.
Solution Approach 2:
The patent applies partial action by selectively applying different drive patterns for different operational phases and conditions. Rather than using a single continuous drive method, the system applies specific drive patterns partially based on detected lamp characteristics and operational requirements, allowing precise power control while extending overall lamp life through targeted parameter adjustment.
