Luminaire Cover Opening for Modular Sensor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamps are limited to a single purpose and require separate production for different applications, lacking flexibility to easily adapt to various functions such as light sensors or emergency lighting systems.
Innovation Solution
A lamp design featuring a transparent cover with a rectangular opening that allows for interchangeable electrical inserts, including sensors and emergency lights, which can be easily installed and maintained, ensuring the sensor monitors the intended space and the electrical supply is protected and easily routed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lamp is designed for a single specific purpose, then the manufacturing process is simple and cost-effective, but the lamp lacks flexibility to adapt to different applications
Solution Approach 1:
The lamp housing is designed with a universal structure that can accommodate multiple different electrical inserts (sensors, emergency lights, etc.) through a standardized opening and fastening mechanism, allowing a single lamp model to serve multiple functions without requiring different production series
Solution Approach 2:
The lamp is divided into modular components: a fixed housing and interchangeable electrical inserts. This segmentation allows the functional elements to be independently replaced or modified while keeping the main structure intact, enabling easy adaptation to different applications
2Measurement precision
If sensors are mounted on the lamp housing, then the lamp can detect environmental conditions, but the sensor may not be properly positioned to monitor the intended space
Solution Approach 1:
The electrical insert containing the sensor can be dynamically positioned and oriented within the lamp housing to achieve optimal monitoring angles and positions for different application scenarios, rather than being fixed in a predetermined location
3Ease of manufacture
If electrical inserts are made interchangeable, then the lamp can be easily modified for different purposes, but the electrical connections become more complex
Solution Approach 1:
The electrical connections for different inserts are merged into a common terminal block or connection system within the housing, allowing multiple interchangeable inserts to share the same electrical interface and reducing the overall complexity of wiring
4Ease of repair
If the transparent cover is removed for maintenance, then the electrical insert can be accessed, but the electrical supply line may be damaged
Solution Approach 1:
A strain relief element is installed beforehand at the electrical connection point to cushion and absorb mechanical stresses, protecting the electrical supply line from damage when the cover is removed or the insert is exchanged during maintenance

AI summary
The lamp has lamp housing (2) that is provided to receive a lighting unit. A partially transparent cover (4) is provided to close the lamp housing. The cover is provided with opening (8) that is used for receiving the replaceable electrical structures (6) such as sensor e.g. light sensor or motion sensor or LED. An electrical wire integration unit (14,16) is integrated in the cover. The length of the opening is 40-70 mm and width of the opening is 10-30 mm. The cover is made of plastic.
