Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamps have fixed reflective surfaces, limiting their ability to change illumination effects and requiring multiple light sources to adjust brightness, which increases production costs and restricts adaptability to environmental or user requirements.
Innovation Solution
A lamp design incorporating a light modulation module with movable light absorbing materials that adjust their positions using electrical fields to create varying light absorbing and penetration regions between the light source and reflective unit, allowing for dynamic control of illumination patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources are added to adjust brightness, then the illumination effect is improved, but the production cost increases
Solution Approach 1:
The reflective surface is made dynamically adjustable through a light modulation module that can change the reflection characteristics in real-time. This allows a single light source to produce variable illumination effects that would traditionally require multiple fixed light sources, thereby reducing production costs while maintaining flexibility in brightness control
Solution Approach 2:
The invention changes the optical parameters of the reflective surface by using a light modulation module with movable light absorbing materials. By adjusting the position and configuration of these materials, the reflection characteristics are dynamically modified, enabling brightness control without adding more light sources
2Ease of manufacture
If the reflective surface is fixed, then the manufacturing complexity is reduced, but the adaptability to environmental or user requirements deteriorates
Solution Approach 1:
The reflective surface incorporates a light modulation module that enables dynamic adjustment of illumination patterns. This allows the lamp to adapt to different environmental conditions and user requirements while maintaining a relatively simple fixed structure for the overall lamp body, thus balancing manufacturing simplicity with operational versatility
Solution Approach 2:
The light modulation module provides multi-functionality to the reflective surface, enabling it to perform multiple illumination functions (different patterns, brightness levels, and effects) within a single fixed structure. This universal design allows the lamp to adapt to various requirements without requiring multiple different lamp designs
3Illumination intensity
If the lamp shape is changed to achieve better illumination effect, then the illumination effect is improved, but the device complexity increases
Solution Approach 1:
Instead of changing the overall lamp shape, the invention modifies the local properties of the reflective surface through the light modulation module. This allows different illumination effects to be achieved by locally adjusting the reflection characteristics at specific areas of the reflective surface, maintaining a simple overall lamp structure while providing diverse illumination patterns
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 the lamp to change its illumination effect by altering the sizes and locations of light absorbing and penetration regions, enhancing adaptability and reducing production costs by eliminating the need for multiple light sources.
Implementation Method 1
The movable light absorbing material is moved to different positions respectively by applying different electrical fields
Implementation Method 2
a region where the movable light absorbing material is absent forms a light penetration region. A portion of the illumination light irradiating the light penetration region penetrates the light penetration region, is transmitted to the reflective unit, is reflected by the reflective unit
Data Source
AI summary
A lamp including a light source, a reflective unit and a light modulation module is provided. The light source provides an illuminating light, and the reflective unit reflects the illuminating light. The light modulation module is disposed between the light source and the reflective unit. In the light modulation module, a region where movable light absorbing materials exist is a light absorbing region, and a region where the movable light absorbing materials are absent is a light penetration region. By applying different electrical fields to the movable light absorbing materials, sizes and locations of the light absorbing region and the light penetration region can be changed. A portion of the illuminating light irradiating the light penetration region penetrates through the light penetration region, is transmitted to the reflective unit, being reflected by the reflective unit, and penetrates through the light penetration region again sequentially.
