A light assembly with a base supporting an area light emitting diode for 360-degree illumination and a flood light emitting diode, a diffuser for light distribution, a movable hanging hook for mounting options, and a removable battery pack with integrated power management for multiple power sources, including AC and DC inputs, allowing for adjustable lighting modes and efficient heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable lighting device provides both area lighting and flood lighting functions, then the versatility and lighting coverage are improved, but the device complexity and structural size increase
Solution Approach 1:
The patent combines both area lighting and flood lighting functions into a single integrated light assembly. The housing contains both an area light source with diffuser and a flood light source, allowing the device to provide multiple lighting functions simultaneously while maintaining a compact portable form factor.
Solution Approach 2:
The light assembly is designed as a multi-functional device that can perform both area illumination and flood illumination tasks. The housing integrates multiple light sources, power management components, and mounting mechanisms to enable the single device to serve multiple lighting needs in various work environments.
2Adaptability or versatility
If a portable lighting device includes integrated power management for multiple power sources, then the adaptability and operational flexibility are improved, but the device complexity increases
Solution Approach 1:
The power management system is designed to accept multiple power source types including rechargeable battery packs and AC power inputs. The housing integrates circuitry that can automatically or manually switch between different power sources, allowing the device to operate flexibly in various power availability scenarios without requiring separate devices for each power type.
3Ease of operation
If a portable lighting device includes a movable hanging hook for flexible mounting, then the ease of operation and mounting flexibility are improved, but the device complexity increases
Solution Approach 1:
The hanging hook is designed as a movable mechanism that can be extended from and retracted into the housing. This dynamic component allows the user to configure the mounting options based on the application needs - extending the hook for hanging mounting or retracting it for portable handheld use - without adding significant structural complexity to the overall device.
4Illumination intensity
If a portable lighting device provides 360-degree illumination and side lighting, then the illumination coverage and workspace coverage are improved, but the device complexity and size increase
Solution Approach 1:
The patent employs different light sources and optical characteristics for different lighting needs. The area light source with diffuser provides 360-degree omnidirectional illumination for general workspace coverage, while the flood light source provides directed side lighting for task-specific illumination. Each light source is optimized for its specific function, achieving comprehensive lighting coverage without requiring a single complex optical system.
