Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track lighting systems lack versatility in accommodating different types of lamps, particularly AC mains powered lamps, limiting their flexibility and aesthetic appeal.
Innovation Solution
Incorporating an upconverter in the lighting fixture to convert a safety voltage from the lighting track into a higher voltage suitable for AC mains powered lamps, while maintaining safety through the use of Separated Extra Low Voltage (SELV) systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a track lighting system uses a safety voltage (low voltage) distribution, then safety is improved, but versatility in accommodating different lamp types deteriorates
Solution Approach 1:
The patent introduces an upconverter as an intermediary device between the safety voltage track lighting system and AC mains powered lamps. The upconverter receives the safe low voltage from the lighting track and converts it to a higher voltage suitable for AC lamps, thereby enabling the system to accommodate different lamp types while maintaining safety. This mediator resolves the contradiction by allowing the track system to remain safe while supporting versatile lamp connections.
Solution Approach 2:
The lighting fixture is designed with multi-functionality to accommodate both low voltage lamps and AC mains powered lamps. By incorporating an upconverter, the fixture can operate with different voltage requirements, making it universal. This allows a single track lighting system to serve multiple purposes and support various lamp types without compromising safety.
2Reliability
If the lighting track distributes safety voltage, then safety is improved, but the ability to power AC mains powered lamps deteriorates
Solution Approach 1:
The upconverter acts as a mediator that bridges the gap between the safety voltage distribution system and AC mains powered lamps. It receives the safe voltage from the track and converts it to the appropriate higher voltage for AC lamps, enabling the track system to power diverse lamp types while maintaining safety standards.
Solution Approach 2:
The upconverter changes the voltage parameter from a low safety voltage to a higher voltage suitable for AC lamps. This parameter transformation allows the same track lighting infrastructure to support different lamp types by adjusting the voltage level at the point of connection without altering the track's original safe voltage distribution.
3Adaptability or versatility
If an upconverter is added to the lighting fixture, then versatility is improved, but device complexity increases
Solution Approach 1:
The upconverter is integrated into the lighting fixture as a compact intermediary component. By placing it within the fixture rather than requiring a separate external device, the patent minimizes the increase in overall system complexity while still providing the necessary voltage conversion capability for versatility.
