Modular LED Lamp Assembly With Waterproof Concentric Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lamps with module group structures lack effective waterproofing, leading to potential damage and increased costs when installed outdoors, necessitating the replacement of the entire lamp housing upon failure.
Innovation Solution
A lamp module group design incorporating a concentric male and female terminal system with sealing layers and a housing structure that allows for modular replacement, ensuring waterproofing and heat dissipation while enabling rotational coaxial connection and power extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a module group without waterproof function is installed in the lamp housing, then the module group can be easily replaced when failed, but the lamp housing must provide waterproofing which increases its complexity and cost
Solution Approach 1:
The patent divides the lamp system into separate functional modules: a non-waterproof lamp housing and a waterproof module group. The module group includes the LED lamp board, power supply driving module, and concentric male terminal assembly, all integrated within a waterproof housing. This segmentation allows the lamp housing to remain simple while the module group handles waterproofing, enabling easy replacement of failed modules without replacing the entire lamp housing.
2Reliability
If the entire lamp housing is replaced when the lamp fails, then reliability is improved, but cost and waste increase significantly
Solution Approach 1:
The patent enables selective replacement of only the failed module group while retaining the functional lamp housing. The modular design with standardized interfaces (concentric male and female terminals) allows quick identification and replacement of the module group containing the LED lamp board or power supply driving module. This recovers the value of the lamp housing and reduces material waste compared to replacing the entire lamp assembly.
3Ease of repair
If modular design is implemented for easy replacement, then ease of repair improves, but the waterproof connection between modules becomes more complex
Solution Approach 1:
The patent employs a nested structure where the concentric male terminal is inserted into the concentric female terminal, with the male terminal's outer conductive pipe fitting inside the female terminal's inner conductive pipe. This nested design provides both electrical connection and waterproof sealing in a single integrated action. The concentric structure with O-ring seals ensures waterproofing while maintaining ease of module replacement through simple insertion and extraction movements.

AI summary
A lamp module group can include a housing defining a cavity, the housing defining an opening to the cavity at a first end of the housing, the housing defining a threaded portion at the first end, the cavity at least partially filled with a sealing material, the housing including a column positioned opposite from the first end; an LED lamp board positioned within the cavity; a power supply driving module positioned within the cavity between the LED lamp board and the column; a first concentric terminal positioned at least partially within the column; a reflecting cup configured to reflect light emitted from the LED lamp board; and a lens positioned over the LED, the lens received within the reflecting cup.
