Solution Overview
Problem
LED lamps are designed for specific sockets and require a complete redesign to fit into existing tungsten lamp fixtures, limiting their versatility and compatibility with different lighting fixtures.
Innovation Solution
A modular LED retrofit lamp system featuring a high-power LED light engine with an integrated optics mount, serviceable dimmable driver, and adaptable mounting options for various fixtures, allowing it to replace a range of tungsten lamps up to 500 watt equivalents and maintain dimming capabilities, including PAR56, PAR38, and other fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LED lamps are designed for specific sockets, then they achieve optimized performance for that socket, but they lose compatibility with existing tungsten lamp fixtures
Solution Approach 1:
The LED lamp is designed with a universal mounting structure that can accommodate multiple socket types (PAR56, PAR38, A19, etc.) through interchangeable adapters. The basic LED engine remains the same while different mounting adapters enable compatibility with various existing fixtures, allowing one LED lamp design to serve multiple functions across different socket types.
2Reliability
If a complete redesign of the lamp is required to fit existing fixtures, then the LED can be optimized for the new fixture, but the complexity and cost of implementation increases
Solution Approach 1:
The LED lamp system is divided into two independent segments: a basic LED engine that contains the light-emitting components and driver circuitry, and separate mounting adapters that interface with different socket types. This segmentation allows the LED engine to remain unchanged while only the simple mounting adapter needs to be selected or modified for each fixture type, dramatically reducing overall system complexity.
Solution Approach 2:
Mounting adapters serve as intermediary components between the standardized LED engine and various existing fixture sockets. These adapters translate between the universal LED mounting interface and different socket types (E26, E27, BAY15, etc.), eliminating the need to redesign the entire LED lamp for each fixture while maintaining full compatibility.
3Loss of energy
If LED lamps replace high-wattage tungsten lamps, then energy consumption is reduced, but ensuring equivalent light output and dimming performance becomes more challenging
Solution Approach 1:
The patent replaces traditional tungsten filament heating elements with LED light-emitting diodes that convert electrical energy directly to light through electroluminescence. This substitution is enabled by integrating a constant-current LED driver circuit that replaces the simple resistive heating mechanism, providing efficient energy conversion while maintaining controllable light output and dimming capabilities through electronic control.
