Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing process for vehicle lamps requires separate production of multiple micro incident lenses, micro exit lenses, and collimators to achieve specific light distribution characteristics, leading to increased costs and decreased productivity.
Innovation Solution
A vehicle lamp design that uses a plurality of lamp modules, each comprising a light source unit, an optical path adjustment unit, and an optical unit, where the light source chips are arranged in a left-right direction, and the optical path adjustment unit includes collimators with vertically spaced central axes to adjust light irradiation patterns without the need for custom lenses and collimators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate micro incident lenses, micro exit lenses, and collimators are manufactured to achieve specific light distribution characteristics, then the light distribution characteristics of the beam pattern are satisfied, but manufacturing costs increase and productivity decreases
Solution Approach 1:
The patent combines multiple separate optical components (incident lenses, exit lenses, and collimators) into a single integrated optical unit. This integration maintains the light distribution characteristics while simplifying the manufacturing process, as the optical unit can be produced as one piece rather than assembling multiple separate components, thereby improving productivity without sacrificing optical performance
Solution Approach 2:
The optical unit is designed to perform multiple functions simultaneously: it acts as both an incident lens and an exit lens, and incorporates collimator functionality. This multi-functional design eliminates the need for separate manufacturing of multiple specialized components, reducing both cost and manufacturing complexity while achieving the required beam pattern and light distribution characteristics

Implementation Method 1
a light source unit that generates light and includes a plurality of light source chips
Implementation Method 2
a collimator is used to adjust the path of the light so that the light from the light source is incident on the micro incident lenses with a minimal loss
Implementation Method 3
light incident from a light source to a plurality of micro incident lenses is emitted through a plurality of micro exit lenses to form a beam pattern suitable for the use of a vehicle lamp
