Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light emitting apparatuses are cumbersome and costly due to the need for multiple units to achieve varying light emitting intensities and color temperatures, occupying large spaces and requiring individual manufacturing for different applications.
Innovation Solution
A light emitting apparatus comprising a first light emitting portion with a color temperature of 5700K or more and a second light emitting portion capable of adjusting color temperature, both independently driven, with a controller to manage voltage and output light characteristics, allowing for a single package to produce a range of light emitting intensities and color temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light emitting apparatuses are used to achieve different color temperatures and intensities, then the desired lighting effects are obtained, but the manufacturing cost and mounting space increase
Solution Approach 1:
The patent combines multiple light emitting diodes with different color temperatures (first, second, and third light emitting diodes emitting blue, green, and red light respectively) into a single integrated package. This merging of multiple light sources into one apparatus eliminates the need for separate mounting of multiple devices while maintaining the ability to produce varied color temperatures and intensities through independent control of each LED type.
2Adaptability or versatility
If multiple light emitting apparatuses are manufactured for different uses, then specific lighting requirements are met, but the manufacturing cost increases
Solution Approach 1:
The patent creates a universal light emitting apparatus that can perform multiple lighting functions by integrating different types of light emitting diodes (blue, green, red) with different color temperatures within a single device. The controller enables selective activation and intensity adjustment of each LED type, allowing the single apparatus to adapt to various lighting applications and requirements, thereby eliminating the need to manufacture and stock multiple specialized devices.
3Area of stationary object
If a single package contains multiple light emitting portions, then space efficiency and cost are improved, but the device complexity increases
Solution Approach 1:
The patent divides the light emitting apparatus into distinct functional segments: first, second, and third light emitting diodes for different color temperatures, a controller for independent management of each segment, and a housing that organizes these components. This segmentation allows each component to perform its specific function while being coordinated through the controller, managing the internal complexity through structured organization rather than a monolithic design.
