Solution Overview
Problem
Current light devices, despite advancements in LED technology, lack decorative features while maintaining a low cost, and there is a need for solutions that can provide both luminous efficacy and aesthetic appeal, particularly in replacing traditional Tungsten bulbs.
Innovation Solution
A light apparatus comprising a driver circuit, an LED plate, an optical light guide, a connector, and a bulb shell, where the optical light guide forms an enlightened pattern using transparent materials like PMMA or PC, with adjustable light paths and color spectrum modification, allowing for various designs that mimic traditional bulbs while utilizing LED technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional Tungsten filament bulbs are used to achieve decorative light effects, then aesthetic appeal and decorative features are improved, but luminous efficacy deteriorates and energy consumption increases
Solution Approach 1:
The patent uses an optical light guide with specific structural features (curved edges, protruding structures, fork patterns) to copy and simulate the visual appearance of traditional Tungsten filaments and bulb structures. The light guide transforms LED light to create enlightened patterns that replicate the aesthetic characteristics of incandescent bulbs, allowing LED technology to provide both energy efficiency and decorative appeal.
2Use of energy by moving object
If advanced LED technology is used to improve luminous efficacy, then energy efficiency is improved, but decorative features and aesthetic appeal deteriorate
Solution Approach 1:
The optical light guide acts as an intermediary component between the LED light source and the external environment. It receives light from the LED module and transforms its distribution pattern to create decorative effects. The light guide's structural features (curved edges, protruding structures, fork patterns) mediate the light to produce enlightened patterns that simulate traditional bulb aesthetics while maintaining LED energy efficiency.
Solution Approach 2:
The patent applies local quality by creating specific structural features at different locations of the optical light guide. The curved edges, protruding structures, and fork patterns are positioned to create localized light distribution characteristics that simulate specific visual features of traditional bulbs. This allows different parts of the light guide to produce different decorative effects while maintaining overall energy efficiency.
3Ease of manufacture
If simple LED modules are used to reduce cost, then manufacturing cost is reduced, but decorative light effects and aesthetic appeal deteriorate
Solution Approach 1:
The optical light guide serves as a cost-effective intermediary that transforms simple LED light output into complex decorative patterns. Instead of using expensive LED modules with built-in decorative features, the patent uses a relatively simple and inexpensive light guide with molded structural features to create the aesthetic effects, maintaining low manufacturing costs while achieving decorative appeal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables the creation of decorative light effects with enhanced luminous efficacy, offering cost-effective alternatives to traditional bulbs by simulating Tungsten filament bulbs and providing customizable patterns and light distribution, thus addressing both aesthetic and cost considerations.
Implementation Method 1
The optical light guide has a bottom end facing to the first LED module for receiving the first light and has a top end forming an enlightened pattern where the first light escaped from the top end of the optical light guide
Implementation Method 2
For example, the optical light guide is transparent like using transparent PMMA material or PC material and the top end forms a curved edge for light to escape and to form the enlightened pattern
Implementation Method 3
The connector is used for fixing the LED plate to the optical light guide for aligning the first LED module to emit the first light into the bottom end and for transmitting heat of the LED plate to the optical light guide
