Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamp devices with non-light-transmissible lampshades suffer from reduced visual effect and openness due to light shielding, requiring higher power light-emitting elements that increase costs, heat generation, and light spots, while also consuming more power.
Innovation Solution
A light-transmissible element with microstructures, featuring refractive surfaces and adjustable spacing and depth, is integrated into the lamp device to enhance light extraction efficiency and output range, allowing for both visual penetration and illumination states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a non-light-transmissible lampshade is used to shield light, then light shielding capability is improved, but visual effect and openness are worsened
Solution Approach 1:
The lampshade is designed with a light-transmissible structure containing plural microstructures (such as through-holes or recesses) that allow light to pass through. This porous-like structure enables both light shielding in certain directions and light transmission in others, resolving the contradiction between shielding capability and visual effect.
Solution Approach 2:
The invention transitions from a solid opaque lampshade to a structured light-transmissible lampshade with microstructures. By adding dimensional complexity at the micro-scale, the lampshade achieves dual functionality: shielding light from direct view while allowing light transmission and maintaining visual openness.
2Illumination intensity
If high-power light-emitting elements are used to increase luminous flux, then light output is improved, but heat generation and power consumption are worsened
Solution Approach 1:
The invention changes the optical parameters of the lampshade by introducing microstructures with specific geometries (spacing, depth, shapes). These parameter changes enhance light extraction efficiency and distribution, allowing standard power light-emitting elements to achieve better lighting effects without increasing heat generation.
Solution Approach 2:
Instead of increasing mechanical/electrical power to improve light output, the invention uses optical structure design (microstructures) to enhance light extraction and distribution. This substitutes structural optimization for power increase, reducing heat generation while maintaining or improving luminous flux.
3Area of stationary object
If multiple light-emitting elements are used to increase light output range, then coverage area is improved, but device complexity and installation cost are worsened
Solution Approach 1:
The lampshade is segmented into multiple microstructures (through-holes or recesses) that independently transmit and distribute light. This segmentation allows a single light-emitting element to illuminate multiple directions and areas, replacing the need for multiple light-emitting elements and reducing system complexity.
Solution Approach 2:
The light-transmissible lampshade structure serves multiple functions: it transmits light, distributes light to different areas, and maintains structural integrity. This multi-functional design allows a single light-emitting element to achieve the lighting coverage that would otherwise require multiple elements.
4Object-affected harmful factors
If conventional lampshade structure is used for light shielding, then shielding function is improved, but light extraction efficiency is worsened
Solution Approach 1:
The lampshade adopts a light-transmissible structure with plural microstructures that allow light to pass through. This porous-like structure fundamentally changes the light interaction from shielding to transmission, dramatically improving light extraction efficiency while maintaining appropriate shielding in certain directions.
Solution Approach 2:
Instead of using a solid opaque structure to shield light, the invention inverts the approach by using a light-transmissible structure with microstructures. This inversion allows light to pass through the lampshade, transforming it from a light-blocking element to a light-transmitting and distributing element, thereby improving light extraction efficiency.

AI summary
A light-transmissible element and a lamp device using the light-transmissible element are provided. The light-transmissible element includes a light-inputting surface, a first light-outputting surface, a second light-outputting surface and plural microstructures. The first light-outputting surface and the second light-outputting surface are located beside two opposite sides of the light-inputting surface. The plural microstructures are formed on the second light-outputting surface. The plural light beams from the light-inputting surface are received and refracted by the plural microstructures. Consequently, a luminous flux of the light beams received and refracted by each first refractive surface is higher than a luminous flux of the light beams received and refracted by each second refractive surface. Due to this design, the light extraction efficiency of the overall lamp device is increased, the light output range is adjustable and the generation of the light spots is reduced.
