Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high-wattage light-emitting modules are used to provide bright light, then illumination intensity is improved, but heat generation increases causing reduced service life and performance of the control module
Solution Approach 1:
The lighting device is divided into distinct functional modules: light-emitting modules mounted on main bodies, a control module housed in a separate casing, and supporting structures. This segmentation isolates the heat-generating light-emitting modules from the control module, allowing high-wattage LEDs to operate at full brightness without compromising control module reliability.
Solution Approach 2:
Supporting structures and heat dissipation components act as intermediaries between the high-wattage light-emitting modules and the control module. These intermediaries manage thermal energy transfer, preventing excessive heat from reaching the control module while maintaining the high illumination output required for the application.
2Illumination intensity
If light-emitting modules are exposed to high temperature and high humidity environments, then bright light output is maintained, but service life and performance deteriorate
Solution Approach 1:
The device separates environmental exposure zones: the light-emitting modules face the harsh external environment (high temperature and humidity) to maintain bright light output, while the control module is housed in a protected casing that isolates it from these adverse conditions, preserving its service life and performance.
Solution Approach 2:
Different parts of the device have different protective qualities suited to their functions. The light-emitting modules have robust, weather-resistant construction for external exposure, while the control module receives enhanced protection through its dedicated casing, creating local quality differences that optimize both illumination and reliability in harsh environments.
3Device complexity
If control module is placed close to light-emitting modules for compact design, then device complexity is reduced, but heat transfer affects control module performance
Solution Approach 1:
The device uses modular segmentation with standardized mounting structures and connection interfaces. The control module housing and light-emitting module assemblies are separate but easily connectable units, maintaining structural simplicity while ensuring adequate thermal separation to protect control module performance.

AI summary
A lighting device includes a plurality of main bodies, a first casing, a plurality of second casings, a control module, and a plurality of light-emitting modules. One side of each of the plurality of main bodies has the light-emitting modules arranged thereon, and the light-emitting module is electrically connected to the control module. One second casing is fixedly disposed on another side of each of the plurality of main bodies that is opposite to the one side where the light-emitting module is disposed, and a passage is formed between the second casing and the main body. The control module with a plug-in design is disposed in the first casing, so that the control module is arranged away from the plurality of light-emitting modules.
