Solution Overview
Problem
Traditional lighting systems, such as incandescent and fluorescent bulbs, lack the energy efficiency and design flexibility of LED lighting systems, and there is a need for LED solutions that mimic the visual appearance of traditional bulbs to facilitate seamless replacements.
Innovation Solution
An LED lighting system that includes an optic element configured to resemble a filament, with a base that provides an electrical path and surface treatments on the optic element to simulate the appearance and light distribution of traditional incandescent bulbs, allowing for color changes by adjusting the current delivered to the LED assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED assemblies are used to replace traditional lighting systems, then energy efficiency and durability are improved, but visual appearance and design flexibility may deteriorate
Solution Approach 1:
The patent applies the copying principle by using an optic element that replicates the visual appearance of a traditional incandescent filament. The optic element is configured with a light guide that transmits LED light through a path that mimics the shape and structure of a filament, allowing the LED bulb to visually resemble traditional bulbs while maintaining LED energy efficiency and durability advantages
2Shape
If optic elements with light guides are used to transmit light, then visual appearance mimicking traditional bulbs is improved, but device complexity increases
Solution Approach 1:
The patent applies the merging principle by integrating the optic element and light guide into a single unified component. The optic element is formed as an elongated solid member with an internal passage that serves as the light guide, combining the structural and optical functions into one piece rather than separate components, thereby reducing assembly complexity while maintaining the filament-mimicking visual appearance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
An LED lighting system includes an LED assembly for emitting light when energized through an electrical path. An optic element in the enclosure receives the light emitted by the LED assembly and disperses the light from the enclosure. The optic element comprises a light guide for transmitting light from the LED assembly to a light emitting portion where the light emitting portion is configured to visually appear like a filament in a traditional bulb.
