Exterior Accent Lamp Mounting on Headlamp Lens Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aftermarket LED lamps for motor vehicles require complex installation processes, involving tool usage and mechanical skill, and pose risks of damaging factory headlamps and allowing water entry, making them inconvenient for average consumers.
Innovation Solution
A motor vehicle accent lighting system comprising a housing with a light-emitting device mounted on the exterior surface of the lens cover, directing light towards the reflector to provide chromatic illumination without interfering with primary lighting, using a thermoplastic adhesive for secure attachment and a wireless controller for color and intensity adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If aftermarket LED lamps are installed by removing and disassembling factory headlamps, then chromatic lighting customization is achieved, but the risk of damaging factory headlamps and allowing water entry increases
Solution Approach 1:
The invention extracts the lighting customization function from the factory headlamp assembly by using a separate accent lamp that attaches to the exterior of the lens cover. This allows chromatic lighting to be added without modifying or disassembling the factory headlamp, thereby maintaining headlamp integrity while achieving lighting versatility.
Solution Approach 2:
The lighting system is segmented into two independent components: the factory headlamp assembly and the separate accent lamp. The accent lamp includes its own housing, light-emitting device, and mounting structure, allowing it to function independently without interfering with the primary headlamp system.
2Adaptability or versatility
If complex installation procedures with tools and mechanical skill are required, then LED halo rings can be installed in conventional headlamps, but the convenience for average consumers decreases
Solution Approach 1:
The accent lamp is designed with a self-contained mounting system that attaches directly to the exterior surface of the lens cover using adhesive or mechanical fasteners. This eliminates the need for consumers to perform complex disassembly, heating, or sealing procedures, making installation simple and accessible to average consumers.
Solution Approach 2:
The mounting surface and attachment mechanisms are pre-configured on the accent lamp housing during manufacturing. This preliminary preparation allows for straightforward installation without requiring consumers to perform complex preparation steps such as heating the headlamp or creating mounting slots.
3Adaptability or versatility
If the lens cover is removed to access the reflector, then LED lamps can be mounted inside the headlamp, but the sealing between lens cover and reflector is compromised
Solution Approach 1:
The invention extracts the mounting location from the interior of the headlamp to the exterior surface of the lens cover. This eliminates the need to break the seal between the lens cover and reflector, as the accent lamp attaches to the outside surface without requiring disassembly or creation of openings in the sealed assembly.
4Adaptability or versatility
If drilling holes or puncturing vent patches is done to route wires, then electric power can be supplied to LED lamps, but the risk of water entry increases
Solution Approach 1:
The accent lamp is designed as a self-contained unit with pre-routed wiring that exits through the housing. This eliminates the need to drill holes or puncture vent patches in the factory headlamp assembly, as all electrical connections are made externally without compromising the sealed structure.

AI summary
A method of providing accent ornamental illumination to a lamp of a motor vehicle comprising providing an accent lamp comprising a housing and a light-emitting device disposed within the housing; mounting the housing to an exterior surface of the lens cover of the vehicle lamp; and arranging the light-emitting device such that, when the housing is mounted to the exterior surface of the lens cover of the lamp, light emitted from the light-emitting device passes through the lens cover from outside the lens cover towards a lamp reflector of the vehicle lamp and illuminates the reflector. A motor vehicle lamp combination comprising, in combination, a motor vehicle lamp and an accent lamp also provided wherein, when the accent lamp is mounted on a lens cover of the motor vehicle lamp, light emitted from the light-emitting device is directed towards the reflector.
