Vehicle Lamp Module Light Blocker for Colored Spot Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamp modules project colored over-bright spots in low-beam and high-beam areas due to direct light emission from the light source, which is not effectively managed by known lighting modules.
Innovation Solution
A vehicle lamp module design incorporating a light blocker arranged between the light source and lens, integrated with a radiator to dissipate heat, which blocks or reflects direct light rays parallel to the optical axis, thereby preventing undesired projection and achieving a more compact structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a light source is positioned close to the lens for compact design, then the device size is reduced, but colored over-bright spots appear in the projected light beam
Solution Approach 1:
A light blocker is introduced as an intermediary element between the light source and lens. This blocker selectively intercepts direct light rays that would otherwise cause colored over-bright spots, while allowing reflected light to pass through. The light blocker is integrated with the radiator structure, forming a unified component that addresses both optical quality and thermal management.
Solution Approach 2:
The harmful direct light rays are extracted or separated from the useful reflected light path. By positioning the light blocker to specifically block direct rays parallel to the optical axis while permitting reflected rays to reach the lens, the solution extracts the harmful portion without compromising the beneficial light transmission.
2Object-generated harmful factors
If a light blocker is added to block direct light rays, then optical quality is improved, but device complexity increases
Solution Approach 1:
The light blocker is merged with the radiator to form an integral structure. This combination eliminates the need for separate components, reducing assembly steps and structural complexity. The unified design allows the same structure to perform both thermal dissipation and optical blocking functions simultaneously.
Solution Approach 2:
The integrated radiator-light blocker structure serves multiple functions: it dissipates heat from the light source, blocks direct light rays to prevent colored spots, and maintains the compact overall design. This multi-functional approach reduces the total number of components needed in the system.
3Volume of moving object
If the light source is positioned close to the lens, then heat dissipation becomes more difficult, but the device remains compact
Solution Approach 1:
The radiator is merged with the light blocker structure, creating a unified thermal management and optical control system. This integration allows efficient heat dissipation close to the light source without requiring additional space for separate cooling components.
Solution Approach 2:
The radiator structure serves itself by being integrated into the light blocker assembly. The same structure that blocks light also provides thermal dissipation pathways, eliminating the need for dedicated cooling systems and maintaining compact dimensions while managing heat effectively.
