Innovation Solution
A modular LED lamp system comprising a light-emitting diode (LED) unit, heat dissipation assembly, LED driver assembly, and casing assembly, which can be configured to fit various lamp bases and fixtures, including screw, bayonet, and prong bases, with passive and active cooling options, and dimmable drivers, allowing for retrofitting of incandescent fixtures into energy-efficient LED systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LED lamps are designed for specific fixtures with dedicated sockets, then the LED lamp can function properly in its intended fixture, but the LED lamp cannot be adapted to fit into existing lamp fixtures of different types
Solution Approach 1:
The patent applies universality by designing a single LED lamp module that can function across multiple fixture types. The module incorporates a universal socket assembly with multiple contact configurations that can adapt to different base types (screw, bayonet, prong), allowing one LED lamp design to replace various incandescent bulb types without requiring fixture redesign.
Solution Approach 2:
The patent segments the LED lamp into modular components: an LED engine assembly, a heat dissipation assembly, and a universal socket assembly. This segmentation allows the socket portion to be adapted for different fixtures while keeping the core LED lighting module unchanged, enabling versatility without compromising functional integrity.
2Reliability
If a complete redesign of the lamp is required to fit into existing fixtures, then the LED lamp can be optimized for specific fixture requirements, but the development time and cost increase significantly
Solution Approach 1:
The universal socket assembly serves multiple fixture types with a single design, eliminating the need for multiple LED lamp variants. This universality reduces development complexity and manufacturing costs while maintaining proper integration with existing fixtures across different base types.
Solution Approach 2:
The universal socket assembly acts as an intermediary component between the LED engine and various fixture types. It provides a standardized interface that adapts to different fixture requirements, simplifying the integration process and reducing development effort compared to designing custom connectors for each fixture type.
3Ease of manufacture
If LED lamps use fixed socket designs, then the manufacturing process is simplified, but the lamps cannot be retrofitted into existing incandescent fixtures
Solution Approach 1:
The patent segments the lighting system into a standardized LED engine module and an adaptable universal socket assembly. This segmentation allows the core LED module to be manufactured efficiently with fixed processes, while the socket portion provides retrofit capability through its multi-configurable contact design.
Solution Approach 2:
The universal socket assembly provides retrofit capability across multiple fixture types while maintaining standardized manufacturing processes for the LED engine. The socket's ability to accommodate different base types enables widespread retrofitting without requiring complex custom manufacturing for each application.
