Innovation Solution
A light source apparatus comprising multiple laser light sources, a heat-conductive holding section, and strategically arranged lenses to control the spread angle of light, allowing for enhanced luminance and compactness, with the holding section acting as a heatsink to manage heat and the lenses optimizing light distribution in both the fast and slow axis directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple laser light sources are arranged to increase luminance, then the luminance is improved, but the apparatus size increases
Solution Approach 1:
The patent combines multiple laser light sources and their corresponding lenses into a single integrated holding section. The holding section is designed to hold multiple laser light sources arranged in a matrix pattern, with each light source having its own lens positioned directly above it. This merging of multiple components into one unified structure increases luminance through multiple light sources while preventing apparatus size increase by eliminating the need for separate housings or mounting structures for each component.
Solution Approach 2:
The holding section serves multiple functions simultaneously: it provides mechanical support for the laser light sources, positions the lenses, manages heat dissipation, and maintains precise alignment between light sources and lenses. This multi-functionality allows the apparatus to achieve high luminance with multiple light sources while keeping the overall structure compact, as a single component performs what would traditionally require multiple separate elements.
2Ease of operation
If lenses are added to control light spread angle, then the light distribution is improved, but the device complexity increases
Solution Approach 1:
The lenses are integrated directly into the holding section structure, with each lens positioned immediately above its corresponding laser light source. This combination eliminates the need for separate lens mounting mechanisms, adjustment devices, or additional structural components. The light distribution control function is achieved through this simple integrated arrangement, improving ease of operation while minimizing device complexity.
Solution Approach 2:
Each lens in the array is designed to control the light spread angle for its specific corresponding laser light source, providing localized optimization of light distribution. This local quality approach allows each lens to be precisely positioned and configured for its specific function, improving overall light distribution control while maintaining a simple, repetitive structural pattern that does not significantly increase device complexity.
3Temperature
If a heat-conductive holding section is used to manage heat, then the thermal management is improved, but the manufacturing complexity increases
Solution Approach 1:
The holding section is designed as a multi-functional component that simultaneously provides mechanical support, precise positioning, and heat dissipation. By integrating the thermal management function into the existing structural holding section rather than adding a separate heatsink system, the patent improves heat management while avoiding the increased manufacturing complexity that would result from multiple separate thermal management components.
Solution Approach 2:
The heat-conductive properties are incorporated directly into the holding section material and structure, merging the thermal management function with the mechanical support structure. This integration eliminates the need for separate heatsinks, thermal interfaces, or additional thermal management components, thereby improving heat management capability while maintaining manufacturing simplicity through a unified, single-piece or minimally-assembled structure.
