Combination LED Lamp Integrating Backup and Tail Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting systems require multiple lamps to achieve adequate illumination, which occupy more space and can be cumbersome, especially in vehicles where multiple back-up and stop/turn/tail lamps are needed.
Innovation Solution
A combination lamp that integrates multiple light sources, such as LEDs, into a single unitary configuration, allowing for independent activation of each lamp type, reducing overall space usage while maintaining or enhancing illumination levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple separate lamps are used to provide adequate illumination, then the illumination requirement is met, but the space occupied and device complexity increase
Solution Approach 1:
The patent combines multiple separate lamps (back-up lamp and stop/turn/tail lamp) into a single unitary combination lamp assembly. The flange-mounted back-up lamp surrounds the stop/turn/tail lamp, integrating two previously separate lighting functions into one compact unit that occupies less space while providing equivalent or improved illumination.
Solution Approach 2:
The combination lamp assembly performs multiple lighting functions simultaneously - it serves as both a back-up lamp (when the vehicle reverses) and a stop/turn/tail lamp (when braking or signaling). This multi-functional design eliminates the need for separate dedicated lamps for each function, reducing overall space requirements.
2Illumination intensity
If multiple separate lamps are used to provide adequate illumination, then the illumination requirement is met, but the device complexity and number of components increase
Solution Approach 1:
The patent integrates multiple lamp assemblies into a single combination lamp unit with unified mounting structure. The back-up lamp flange and stop/turn/tail lamp are combined into one assembly that mounts as a single unit to the vehicle, reducing the number of separate components and simplifying installation and maintenance.
Solution Approach 2:
While combining multiple functions, the patent maintains separate electrical circuits and control systems for each lamp type within the unified assembly. This segmentation allows independent operation of back-up and stop/turn/tail functions while keeping the physical mounting structure integrated and simple.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The combination lamp provides equivalent or improved illumination with reduced space requirements, allowing for increased light output without adding bulk, and facilitates easier maintenance and design flexibility.
Implementation Method 1
The LEDs of the flange are preferably activated when the vehicle backs up, thus performing as a back-up lamp

AI summary
The present invention relates to a combination lamp which combines at least two different lamp components in a unitary configuration, preferably reducing the total amount of space taken up for the same amount of illumination produced. The combination lamps are preferably suitable for use on vehicles, light fixtures, lamps, decorative articles, etc., and each lamp component preferably has a power connection element independent from the other lamp components.
