Rotating Vehicle Lamp Reflector With Segmented Light Source
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps have limited design flexibility and increased costs due to the fixed coupling of light sources and reflectors, requiring replacement of the entire module when either component is damaged.
Innovation Solution
A vehicle lamp design where the reflector and light source are separately installable, with the reflector being rotatably coupled to a support, allowing independent adjustment and separation from the light source, enabling independent replacement and adjustment of both components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the light source and reflector are fixedly coupled as one module, then installation easiness and production efficiency are improved, but design layout flexibility deteriorates
Solution Approach 1:
The lamp assembly is segmented into separate functional modules: the light source module with heat radiating fin and the reflector module, which can be independently installed and adjusted. This segmentation allows each component to be optimized separately while maintaining ease of assembly through standardized mounting interfaces.
Solution Approach 2:
The reflector is designed with rotational capability around a vertical axis, transforming it from a static fixed component to a dynamic adjustable element. This dynamic feature enables flexible beam direction control and adaptive lighting patterns while maintaining simple fixed mounting of the light source.
2Stability of the object's composition
If the light source and reflector are fixedly and integrally coupled, then structural stability is improved, but replacement cost increases
Solution Approach 1:
The integral coupling is replaced with separate mounting structures that maintain stable optical alignment while allowing independent replacement. The light source and reflector are secured with stable mounting interfaces but can be individually accessed and replaced without replacing the entire assembly.
Solution Approach 2:
The design enables selective replacement of only the damaged component (light source or reflector) while retaining the functional other component. This partial replacement approach recovers the value of the undamaged component and reduces waste compared to replacing the entire integrated module.
3Temperature
If the light source has a large heat radiating fin to spread heat, then heat dissipation is improved, but installation space requirement increases
Solution Approach 1:
The heat dissipation function is segmented into a separate heat radiating fin module that can be independently sized and optimized. This allows the fin to extend in specific directions to maximize heat dissipation surface area without increasing the overall footprint of the lamp assembly, as the fin is positioned adjacent to rather than integrated with the light source body.

Function Achieved in This Case
This design enhances installation flexibility, reduces replacement costs, and allows for precise light aiming and various irradiation angles, while maintaining efficient light distribution.
Implementation Method 1
A reflector is rotatably coupled with a support. A reflecting body is connected to the reflector to rotate along with a rotation of the reflector, receives the light from the light source, and reflects the light to the reflector.
Implementation Method 2
The reflector may further have a phosphor which is provided on a moving path of light reflected from a reflection surface and may change a wavelength of the light incident from the reflecting body and irradiate the light to the reflection surface.
