Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light bulbs, such as LED bulbs, lack flexibility in designing adjustable luminance and color temperature, resulting in non-uniform illumination and biased arrangements that lead to dim shapes and color gradients.
Innovation Solution
A light bulb design featuring a housing, illuminating component, driving circuit board, and light transmitting component with microstructures that uniformly distribute light along the axial direction, including a lens to focus light and a bulb base for support, allowing for adjustable color temperature and luminance through detachable engaging elements and opal glass diffusing plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional light bulbs are used to provide sufficient luminance, then illumination intensity is improved, but uniformity of illumination deteriorates due to biased arrangements and non-adjustable design
Solution Approach 1:
The light bulb divides the illuminating component into multiple independent light-emitting units (first and second light-emitting components with different color temperatures) that can be independently controlled. This segmentation allows each unit to contribute uniformly to the overall illumination, eliminating the non-uniformity caused by single-source biased arrangements.
Solution Approach 2:
The patent introduces a temporal dimension by enabling dynamic switching and mixing of different color temperature lights over time. This allows the system to achieve uniform illumination across different color temperatures by controlling the timing and intensity of each light-emitting component, rather than relying on static spatial arrangement.
2Adaptability or versatility
If different types of light bulbs are arranged to achieve different color temperatures, then adaptability is improved, but device complexity and uniformity deteriorate due to biased arrangements and dim shapes
Solution Approach 1:
The patent merges multiple light-emitting components with different color temperatures into a single integrated light bulb housing. This consolidation eliminates the need for multiple separate light bulbs and complex spatial arrangements, while maintaining the ability to independently control each color temperature through the driving circuit board.
Solution Approach 2:
The single light bulb housing serves multiple functions by incorporating both first and second light-emitting components that emit different color temperatures. This multi-functional design allows one device to replace multiple specialized light bulbs, achieving adjustable color temperature without increased arrangement complexity.
3Ease of manufacture
If conventional light bulbs use fixed design, then manufacturing simplicity is improved, but adaptability deteriorates due to inability to adjust luminance and color temperature
Solution Approach 1:
The patent transforms the fixed design into a dynamic system by incorporating a driving circuit board that can independently control the luminance and color temperature of each light-emitting component. This allows the light bulb to adapt to different illumination requirements while maintaining a relatively simple physical structure that is easy to manufacture.
