LED Retrofit Adapter for Fluorescent Fixture Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluorescent light fixtures are not compatible with LED lights, requiring retrofitting to accommodate their different power requirements and achieve desirable light distribution.
Innovation Solution
A method and adapter for retrofitting LED bulbs into fluorescent tube fixtures by removing the ballast and fluorescent tube receptacle, wiring the power supply to LED bulb sockets, and mounting the electrical junction box to the reflector housing, allowing LED bulbs to be securely held and distributed across the fixture's reflective housing and lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If fluorescent tube fixtures are used with LED bulbs, then energy efficiency and service life are improved, but compatibility and light distribution are worsened
Solution Approach 1:
The invention divides the LED lighting system into separate functional modules: a power supply unit that accepts mains power input and provides appropriate power output for LED bulbs, and a fixture housing that accommodates standard LED bulbs. This segmentation allows the power supply to be optimized for LED compatibility while the fixture maintains universal adaptability.
Solution Approach 2:
The patent introduces an intermediary power supply device that bridges between mains power and LED bulb requirements. This power supply acts as a mediator, converting and regulating power to be compatible with LED bulbs while allowing them to be used in traditional fluorescent fixtures, thus resolving the compatibility issue.
2Use of energy by moving object
If fluorescent tube fixtures are used with LED bulbs, then energy efficiency is improved, but light distribution is worsened
Solution Approach 1:
The invention incorporates reflective surfaces and diffusive elements at specific locations within the fixture housing to optimize light distribution. The interior surfaces are designed with particular reflectivity properties, and light diffusers are positioned strategically to ensure uniform illumination patterns that compensate for the directional nature of LED bulbs.

AI summary
A method of retrofitting a plurality of LED bulbs to a fluorescent tube fixture with a ballast, a fluorescent tube receptacle, a reflector housing and a lens comprises: removing the lens from the reflector housing; disconnecting the ballast from a mains power supply line and removing the ballast and the fluorescent tube receptacle from the housing. The mains mains power supply is wired to a plurality of Edison socket light-emitting diode (LED) bulb sockets extending from a body defining an electrical junction box and threading a plurality of LED bulbs into the bulb sockets. The electrical junction box is mounted to the reflector housing. The fixture lens is reinstalled to the housing such that the bulb adapter is received in an enclosure defined by the housing and the lens.
