Integrated Vehicle Lamp Assembly for Multi-Function Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lamps, such as low beam lamps, blinkers, and daytime running lights, occupy a large space due to being disposed in individual lamp spaces, necessitating smaller sizes that compromise functionality and convenience.
Innovation Solution
A lamp assembly integrating low beam, blinker, and daytime running light functions into a single module using a refractor and collimators to direct and refract light in multiple directions, allowing for efficient space utilization and convenient installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If low beam lamps, blinkers, and daytime lamps are disposed in individual lamp spaces, then each lamp can be optimized for its specific function, but the total space occupied increases and the overall size becomes large
Solution Approach 1:
The patent combines low beam, blinker, and daytime running light functions into a single integrated lamp assembly. Multiple light sources (halogen bulbs for low beam, LEDs for blinker and DRL) are housed together with shared optical components including a common reflector, lens, and housing structure, thereby reducing the total volume while maintaining functional optimization through dedicated optical paths for each function
Solution Approach 2:
The lamp assembly is designed as a multi-functional unit where a single housing and optical system serve multiple purposes. The reflector and lens structure is universally designed to handle different light types (halogen and LED) and direct them appropriately for low beam illumination, blinker signaling, and daytime running light functions, eliminating the need for separate lamp spaces
2Volume of moving object
If multiple lamp functions are integrated into one module, then space utilization is improved and installation is simplified, but the device complexity increases
Solution Approach 1:
The integrated lamp assembly is segmented into distinct functional modules within a single housing: halogen bulb assembly for low beam, LED assemblies for blinker and DRL, separate collimators for each light type, and a shared lens system. This segmentation allows each function to be independently optimized and replaced while maintaining the compact integrated structure
Solution Approach 2:
The patent uses intermediate optical components such as collimators and reflectors that mediate between different light sources and the final output. These intermediary elements standardize the light paths and make the integration of multiple light types more manageable, reducing the overall complexity by providing uniform interfaces between different functional components

Implementation Method 1
a refractor that refracts the first light emitted from the first light source
Implementation Method 2
a first collimator to collimate the first light, a second collimator disposed in the second direction of the second light source, and that collimates the second light, and a third collimator disposed in the second direction of the third light source, and that collimates the third light

AI summary
Disclosed are a lamp for a vehicle, and a lamp assembly for a vehicle.. The lamp for a vehicle includes a first light source (20) that emits a first light along a first direction (D1) that is perpendicular to an upward/downward direction, a refractor (10) that refracts the first light emitted from the first light source (20), a second light source (30) that emits a second light toward the refractor (10) along a second direction (D2) that crosses the first direction (D1), and a third light source (40) disposed adjacent to the second light source (30), and that emits a third light toward the refractor (10) along the second direction (D2).
