Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current decorative lighting solutions using LEDs do not effectively utilize the full light-emitting angle of light sources, leading to inefficient energy use and limited number of small light spots, which affects the decorative effect.
Innovation Solution
A lamp design incorporating a light source with a collimating optical element and a light-collecting device with multiple light guiding members that divide the light-emitting angle into smaller parts, creating virtual light-emitting points, allowing for increased parallel light beams and reflection to form a larger number of small light spots without increasing the number of sub-reflectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a collimating optical element with a fixed light-collecting angle is used, then the optical system is simple, but the number of virtual light-emitting points is limited, reducing the decorative effect
Solution Approach 1:
The patent divides the light-collecting function into multiple light guiding members (first, second, and third light guiding members), each collecting light from different angular ranges. This segmentation allows the system to create multiple virtual light-emitting points from a single physical light source, increasing the number of light spots without significantly complicating the overall structure.
Solution Approach 2:
The patent utilizes angular dimension segmentation by directing light from different emission angles through separate light guiding members to the collimating optical element. This angular dimension approach creates multiple virtual light-emitting points in different spatial positions, effectively increasing the number of light spots without adding more physical light sources.
2Illumination intensity
If multiple light guiding members are used to create virtual light-emitting points, then the number of light spots increases, but the device complexity increases
Solution Approach 1:
The patent combines multiple light guiding members into a single integrated light-collecting device that works together with one collimating optical element. This merging approach allows the system to achieve multiple virtual light-emitting points while maintaining a compact and manageable structure, avoiding the need for completely separate optical systems for each light guiding member.
Solution Approach 2:
The collimating optical element serves multiple functions: it receives collimated light from multiple different light guiding members simultaneously and produces parallel light beams for each virtual light-emitting point. This multi-functionality reduces the need for separate collimating elements for each light guiding member, thereby reducing overall device complexity.
3Use of energy by moving object
If the light-collecting angle of the collimating optical element is increased, then more light is collected, but the light-emitting full angle requirement cannot be satisfied
Solution Approach 1:
The patent segments the light collection process by using multiple light guiding members, each responsible for collecting light within a specific angular range. This segmentation allows each light guiding member to have an optimized light-collecting angle that matches its assigned angular range, ensuring complete coverage of the light-emitting full angle while maintaining efficient light collection within each segment.
