Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle headlamps face challenges in efficiently dissipating heat from light-emitting elements while maintaining aesthetic appeal and ensuring easy mounting and alignment of light source modules.
Innovation Solution
A light source module design featuring a heat dissipation plate with an extension part that covers only a portion of the housing, allowing for efficient heat dissipation without affecting the appearance, combined with a mounting system that allows for easy alignment and interchangeable light distribution characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat dissipation plate covers the entire housing, then heat dissipation efficiency is improved, but aesthetic appeal deteriorates
Solution Approach 1:
The heat dissipation plate is designed to cover only a portion of the housing surface rather than the entire surface. This partial coverage approach provides sufficient heat dissipation functionality while preserving aesthetic appeal on the visible portions of the housing, resolving the contradiction between thermal management and appearance.
2Manufacturing precision
If light source modules are fixed in specific positions, then light distribution precision is improved, but mounting flexibility deteriorates
Solution Approach 1:
The mounting structure is designed with universal compatibility, allowing the same mounting interface to accommodate different light source modules with varying light distribution characteristics. The first and second light source modules can be interchangeably mounted in the first and second slots through the standardized mounting structure, providing both positioning precision and mounting flexibility.
3Adaptability or versatility
If multiple light source modules with different light distribution characteristics are used, then lighting functionality is improved, but mounting complexity increases
Solution Approach 1:
A unified mounting structure is provided that can accommodate multiple types of light source modules with different light distribution characteristics. The mounting interface is designed to be compatible with both first and second light source modules, allowing diverse lighting functions to be achieved without increasing mounting complexity through standardized integration.

AI summary
A light source module includes a housing, a light source substrate, a light-emitting element, an optical component, and a heat dissipation plate. The light source substrate is mounted to the housing. The light-emitting element is disposed on the light source substrate. The optical component is provided inside the housing, and light irradiated from the light-emitting element travels through the optical component and exits out of the front surface of the housing. The heat dissipation plate is mounted to the light source substrate. The heat dissipation plate includes a mounting part mounted to the light source substrate, and an extension part extending from the mounting part along the outer surface of the housing. The outer surface of the housing includes a covered part covered with the extension part, and an exposed part that is not covered with the extension part.
