Solution Overview
Problem
Existing light source modules face challenges in effectively dissipating heat generated by light-emitting portions, leading to potential temperature rises that can reduce the lifespan and stability of the light-emitting components.
Innovation Solution
A light source module design featuring a laterally long light source unit with individually attachable heat dissipation units, each comprising sidewall portions facing each other and coupled via a perpendicular coupling portion, enhancing heat dissipation by spreading heat in directions orthogonal to the light source unit's extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional heat dissipation structures are used with light source units, then the structure is simple, but heat dissipation efficiency is insufficient leading to temperature rise
Solution Approach 1:
The heat dissipation structure is divided into multiple independent heat dissipation units, each with its own coupling portion and sidewall portions. This segmentation allows heat to be dissipated from multiple locations simultaneously, improving overall heat dissipation efficiency while keeping each individual unit relatively simple in structure.
Solution Approach 2:
The coupling portions of the heat dissipation units are arranged to extend in a direction perpendicular to the extension direction of the light source unit. This perpendicular arrangement adds a new spatial dimension to heat dissipation, creating a three-dimensional heat dissipation network that significantly enhances heat dissipation efficiency without simply increasing the size of individual components.
2Temperature
If heat dissipation units are arranged parallel to light source unit extension, then alignment is simple, but heat dissipation coverage is limited
Solution Approach 1:
The coupling portions extend in a direction perpendicular to the light source unit's extension direction, creating a two-dimensional grid-like arrangement of heat dissipation units. This perpendicular orientation maximizes heat dissipation coverage by distributing heat dissipation structures across both the length and width of the light source unit, rather than only along its length.
Solution Approach 2:
The heat dissipation units are designed with a universal structure that can be applied to various light source unit configurations. Each unit consists of coupling portions and sidewall portions that can be arranged in different patterns, making the design adaptable to different application requirements while maintaining effective heat dissipation performance.
