Dual-Direction Lampshade With Reflective Inner Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamps lack the ability to efficiently direct light emission from both ends, limiting their decorative and ambient illumination capabilities.
Innovation Solution
A lamp structure featuring a tubular opaque lampshade with reflective inner walls, a tubular transparent transmission cap, and an illumination element, allowing light to emit from both ends through strategically positioned orifices and a rotatable connector for directional adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional single-direction lamp structure is used, then the structure is simple, but the illumination coverage and decorative capability are limited
Solution Approach 1:
The lampshade is divided into two separate orifices positioned at opposite ends, allowing light to be emitted in two opposite directions simultaneously. This segmentation enables the single lamp to illuminate multiple areas without requiring multiple separate lamp units, thereby increasing illumination coverage while maintaining relatively simple structure.
Solution Approach 2:
The lamp structure transitions from single-direction (one-dimensional light emission) to dual-direction (two-dimensional light emission in opposite directions) by positioning orifices at both ends of the lampshade. This dimensional change in light emission direction significantly expands the illumination coverage area.
2Illumination intensity
If an opaque lampshade with reflective inner wall is used, then light directionality is improved, but light transmission is reduced
Solution Approach 1:
The lampshade employs different surface properties at different locations: the inner wall features a reflective coating to redirect light toward the orifices, while the areas around the orifices remain transparent or translucent to allow light transmission. This local differentiation of optical properties enables both light directionality control and efficient light transmission to occur simultaneously in different regions of the same lampshade.
Solution Approach 2:
The reflective inner wall acts as an intermediary that redirects light from the illumination source toward the orifices, while the transparent/oralce regions serve as intermediaries for light transmission. This intermediary reflective surface ensures that light is efficiently directed to the emission points without being lost, maintaining both directionality and transmission efficiency.
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
Enables enhanced decorative and ambient lighting by allowing light to emit from both sides of the lamp and facilitating directional adjustment, thereby improving illumination coverage and aesthetic appeal.
Implementation Method 1
The lampshade is opaque and includes a reflective face formed on an inner wall thereof. One part of lights penetrates through the transmission cap from the illumination element, another lights emit out of a front side of the lamp structure via the reflective face, the transmission cap and the first orifice

AI summary
A lamp structure contains: a lampshade, a transmission cap, and an illumination element. The lampshade is tubular and includes a first orifice and a second orifice which are defined on two ends of the lampshade respectively. The lampshade is opaque and includes a reflective face formed on an inner wall thereof. The transmission cap is tubular and is accommodated in the lampshade, and a gap is defined between the transmission cap and the reflective face. The illumination element is defined between the transmission cap and the reflective face of the lampshade. One part of lights penetrates through the transmission cap from the illumination element, another lights emit out of a front side of the lamp structure via the reflective face, the transmission cap and the first orifice, and the other lights illuminate out of a rear side of the lamp structure via the second orifice.
