Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high-intensity incandescent lights for crowd control are ineffective in distinguishing criminal elements, can be easily avoided with sunglasses or movement, require impractical logistics, and are hazardous due to continuous illumination and non-directional beams, losing effectiveness in ambient light and being unsuitable for vehicular traffic restrictions.
Innovation Solution
A crowd control lighting system employing a plurality of portable, directional LED lights with flashing waveforms that converge to create a constant and intense illumination zone, minimizing illumination of law enforcement officers and using wireless controllers to adjust beam patterns and colors, ensuring continuous and focused illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high intensity incandescent spot lights are used to illuminate the crowd, then the illumination intensity is improved, but the visibility degradation of criminal elements is insufficient and can be overcome with sunglasses or shielding
Solution Approach 1:
The patent employs periodic flashing action by controlling LED lights to flash in synchronized sequences, creating alternating illumination and darkness periods that prevent criminals from adapting or shielding their eyes effectively, thereby maintaining reliable visibility degradation
Solution Approach 2:
The patent utilizes color changes by employing multi-color LED lights that can emit different wavelengths (e.g., red, green, blue) and change colors in sequences, which interferes with the visual system and creates disorientation, enhancing the reliability of visibility degradation against criminal elements
2Illumination intensity
If spot beams are used to assure maximum intensity, then the illumination intensity is improved, but the crowd can easily move such that it is not illuminated
Solution Approach 1:
The patent divides the illumination system into multiple separate LED light sources positioned at different locations, each capable of independently illuminating different zones. This segmentation allows the system to cover a broader area and track crowd movement more effectively than a single spot beam
Solution Approach 2:
The patent implements dynamic control by using controllers that can adjust the illumination patterns, timing, and intensity of each LED light based on detected crowd movement, enabling the system to adapt and track moving crowds while maintaining maximum illumination intensity in targeted zones
3Power
If high intensity incandescent lights are placed on special vehicles, then the power requirement is met, but the logistics problem arises because the special vehicle is not always at the required location
Solution Approach 1:
The patent replaces the mechanical system of vehicle-mounted lights with portable LED lighting systems that can be easily transported and deployed by hand or simple equipment. The LED technology provides sufficient power and intensity without requiring vehicle platforms, thereby eliminating logistics constraints while meeting power requirements
4Adaptability or versatility
If crowds can easily move or shift, then the illumination coverage is reduced, but repositioning vehicles to follow crowd movement is not practical
Solution Approach 1:
The patent segments the illumination system into multiple portable LED units that can be independently positioned and adjusted. This allows the system to cover moving crowds more effectively without requiring complex vehicle repositioning operations, as individual units can be quickly relocated to maintain illumination coverage
Solution Approach 2:
The patent implements dynamic control capabilities that allow the illumination system to adapt to moving crowds through electronic control of multiple LED units, adjusting their operation and positioning without requiring physical repositioning of heavy vehicle-mounted equipment
5Duration of action of moving object
If high intensity lights continuously illuminate or glow after being turned off, then the illumination duration is improved, but it becomes hazardous for law-enforcement because criminal elements can shoot at the lights potentially hitting officers
Solution Approach 1:
The patent employs periodic flashing action where LED lights turn on and off in synchronized sequences, creating periods of illumination followed by darkness. This eliminates the hazard of continuous illumination that attracts gunfire while maintaining effective crowd control through the periodic illumination cycles
Solution Approach 2:
The patent converts the potential harm of illumination duration (attracting gunfire) into a benefit by using controlled periodic illumination that provides sufficient duration for crowd control while creating darkness periods that reduce visibility and deter targeted attacks on the lighting system and officers
6Area of stationary object
If high-intensity lights are not directional, then the illumination coverage is improved, but law-enforcement officers are illuminated equally with the crowd
Solution Approach 1:
The patent applies local quality by using directional LED lights that can be aimed at specific zones or areas within the crowd, providing selective illumination intensity in different locations. This allows differential illumination where officers remain in darker zones while specific crowd areas are intensely illuminated

Data Source
AI summary
A crowd control lighting system includes a plurality of light emitting diode (LED) lights. Each light is configured to emit a flashing directional light beam to at least partially overlap and illuminate a common illumination zone. The common illumination zone is selectable from a plurality of illumination zones and is exterior to a dark zone not illuminated by the plurality of lights.
