Solution Overview
Problem
Existing lighting solutions lack flexibility and cost-effectiveness in providing multiple light settings to satisfy diverse needs, making it difficult to achieve efficient and dynamic lighting solutions.
Innovation Solution
A lighting apparatus comprising multiple sets of LED modules, lenses, and a driver that allows for adjustable light spans by selectively turning on and off different sets of LED modules, controlling their intensities, and directing light through various lenses to achieve different light patterns and colors, with the option to include a third set of LED modules for a main light and motion detection for adaptive lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lighting settings are provided to satisfy diverse needs, then adaptability is improved, but device complexity increases
Solution Approach 1:
The lighting system is divided into multiple independent LED modules (first set, second set, third set) that can be independently controlled. Each module can be selectively activated to provide different lighting modes (wide span, narrow span, main light), enabling multiple lighting settings without requiring a completely different system for each mode.
Solution Approach 2:
The driver dynamically controls the activation and intensity of different LED module sets based on operational modes. The system can switch between different lighting configurations (wide/narrow span, different intensities) in real-time, providing adaptability while maintaining a single unified device structure.
2Adaptability or versatility
If multiple LED modules and lenses are used to achieve adjustable light spans, then lighting flexibility is improved, but manufacturing cost increases
Solution Approach 1:
Multiple LED modules and lenses are integrated into a single unified lighting apparatus structure. The first set, second set, and third set of LED modules share common mounting structures, electrical connections, and housing, allowing the system to achieve adjustable light spans while reducing overall manufacturing complexity and cost compared to separate devices.
Solution Approach 2:
The LED modules and lenses are designed to serve multiple functions within a single system. The same structural components support different LED module sets that can be selectively activated to provide various lighting modes (wide span, narrow span, main light), reducing the need for separate specialized components for each function.

AI summary
A lighting apparatus includes a first set of LED modules, a second set of LED modules, a first lens, a second lens and a driver. The first lens covers the first set of LED modules. The second lens covers the second set of LED modules. The driver supplies a first driving current and a second driving current respectively to the first set of LED module and the second set of LED modules. The driver electively turns on and turns off the first set of LED modules and the second set of LED modules in a first mode and in a second mode. The first light span in the first mode is partially overlapping the second light span in the second mode. The first light span has a smaller span angle than the second light span.
