Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED retrofits for vehicle headlights lack advanced beam shape control capabilities, limiting functionality to that of conventional lamps, such as high and low beams, and do not offer features like cornering light or matrix lighting.
Innovation Solution
The LED retrofit lamp is designed with LEDs arranged into independent groups, controlled by a controller and interface, allowing for various beam patterns and functionalities beyond basic high and low beams, including city and motorway beams, through smartphone apps or vehicle switches, and enabling customizable beam shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LEDs are arranged into independent groups with controller and interface, then beam shape control capability is improved, but device complexity increases
Solution Approach 1:
The LED array is divided into multiple independently controllable groups or modules, where each group can be controlled separately to form different beam patterns. This segmentation allows the system to achieve complex beam shaping capabilities while maintaining manageable control through a controller that receives signals and activates specific LED groups accordingly.
Solution Approach 2:
The system implements dynamic control of LED groups through a controller and interface that can selectively activate different combinations of LED groups based on received control signals. This enables the beam pattern to be dynamically adjusted between various modes (e.g., high beam, low beam, cornering light, matrix lighting) without physical reconfiguration, resolving the contradiction between versatility and complexity.
2Adaptability or versatility
If multiple independent LED groups are controlled separately, then functionality beyond basic high and low beams is achieved, but control system complexity increases
Solution Approach 1:
The controller and interface system is designed to provide multiple lighting functions through a unified control architecture. By selectively activating different combinations of LED groups, the same hardware infrastructure supports diverse functions including high beam, low beam, cornering light, and matrix lighting, thereby achieving multi-functionality without proportionally increasing control system complexity.
Solution Approach 2:
The system controls different LED groups by changing operational parameters such as activation state and intensity levels. The controller receives control signals that modify these parameters to achieve various beam patterns and lighting functions, allowing functionality expansion through parameter variation rather than requiring separate control mechanisms for each function.
3Adaptability or versatility
If LEDs are arranged into independent controllable groups, then beam pattern customization is enabled, but manufacturing complexity increases
Solution Approach 1:
The LED array is manufactured as modular groups that can be independently controlled. This segmentation approach allows for standardized manufacturing of LED groups that can be assembled into different configurations, reducing overall manufacturing complexity while enabling beam pattern customization through selective activation of these pre-manufactured modules.
Solution Approach 2:
Rather than manufacturing different physical configurations for different beam patterns, the system achieves customization by changing operational parameters of the LED groups through electronic control. This approach simplifies manufacturing by producing a single standardized LED array configuration that can be programmed to generate various beam patterns, thereby reducing manufacturing complexity while maintaining customization capability.

AI summary
An LED retrofit lamp is described. The LED retrofit lamp includes LEDs arranged into at least a first group of LEDs and a second group of LEDs, power contacts, an interface and a controller. The power contacts receive electrical power to operate the LEDs. The interface supplies control signals to operate one or more of the first group and the second group of LEDs. The controller receives the control signals and operates the first group of LEDs and the second group of LEDs independent from each other based on the received control signals.
