Solid-State Lighting System for Uninterrupted Event Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems for sports venues lack the ability to provide uninterrupted high-level event lighting during power outages, leading to safety concerns and spectator discomfort, as they either deplete backup power quickly or require complex and costly systems with limited duration and adjustability.
Innovation Solution
A solid-state lighting system that uses existing fixtures to provide uninterrupted event lighting during power interruptions, gradually transitioning to utility and emergency lighting levels, extending duration and quality beyond standard emergency lighting standards, and integrating with existing control systems for remote management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If existing lighting systems use backup power during outages, then emergency lighting is provided, but the duration is limited and lighting intensity must be reduced
Solution Approach 1:
The system dynamically adjusts lighting intensity based on available backup power duration. It transitions from full event lighting intensity to reduced utility lighting intensity, and finally to minimal emergency lighting intensity as backup power depletes, optimizing both duration and intensity at different time stages
Solution Approach 2:
The system applies partial lighting action by providing different levels of illumination to different areas. Event lighting maintains full intensity for critical areas, while utility and emergency areas receive reduced intensity lighting, allowing extended duration through selective power allocation
2Illumination intensity
If complex backup systems are used to maintain high-level lighting, then lighting quality is improved, but system complexity and cost increase
Solution Approach 1:
The same lighting fixtures serve multiple functions: event lighting, utility lighting, and emergency lighting. The system transitions these fixtures between different operational modes based on power availability, eliminating the need for separate dedicated emergency lighting systems and reducing overall system complexity
Solution Approach 2:
The existing lighting infrastructure serves itself by transitioning to backup mode. The system automatically detects power failure and reconfigures existing fixtures for emergency operation without requiring separate backup lighting equipment, reducing system complexity while maintaining lighting quality
3Loss of energy
If lighting levels are suddenly reduced during power outage, then energy consumption is reduced, but spectator comfort and safety deteriorate
Solution Approach 1:
The system performs preliminary action by maintaining full event lighting intensity for a critical initial period during power outage. This ensures spectator comfort and safety are preserved during the most vulnerable transition phase before gradual reduction to energy-saving modes
Solution Approach 2:
The system dynamically manages the transition from high-intensity event lighting to lower-intensity emergency lighting. It maintains high lighting quality initially to prevent spectator discomfort, then gradually reduces intensity to conserve energy, balancing both requirements through time-based dynamic adjustment
