Modular LED Lamp With Replaceable Light Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LED lamp structures are not designed for replaceable light units, leading to environmental waste and resource consumption when individual LED chips become damaged, as the entire lamp is typically discarded and replaced.
Innovation Solution
A modular LED lamp design featuring a heat dissipation housing with annular fins, a metal connector, a driver circuit board, a light unit slice with a substrate and power source wires, and a shade with a screw thread connection, allowing users to replace only the damaged light unit slice without discarding the entire lamp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire LED lamp is discarded when LED chips are damaged, then the lamp can be replaced quickly, but environmental waste increases and resources are consumed
Solution Approach 1:
The LED lamp is divided into separable modules: a reusable housing containing the driver circuit board and heat dissipation structure, and a replaceable light unit containing the LED chips. This segmentation allows only the damaged light unit to be replaced while retaining the functional housing, thereby reducing waste and resource consumption while maintaining quick replacement capability.
2Device complexity
If the entire LED lamp is discarded when LED chips are damaged, then the lamp structure remains simple, but cost increases due to replacing functional components
Solution Approach 1:
The lamp structure is segmented into a permanent housing and a detachable light unit with standardized connection interfaces. This modular design maintains structural simplicity while enabling cost-effective maintenance by allowing users to replace only the inexpensive light unit rather than the entire lamp, thus reducing overall cost.
3Loss of substance
If the light unit is made replaceable, then environmental protection and cost savings are achieved, but the lamp structure becomes more complex
Solution Approach 1:
The lamp is segmented into modular components with standardized interfaces: a housing with mounting structures and a light unit with corresponding connection features. This segmentation enables replaceability for environmental and economic benefits while controlling complexity through standardization and modular design principles.
Solution Approach 2:
The housing is designed as a universal platform that can accommodate different light units through standardized mounting interfaces. This universality allows the same housing to support various LED configurations, reducing overall system complexity while enabling flexible replacement and upgrade options.
