Existing linear lighting systems face challenges with high installation effort, limited heat dissipation, and inflexible installation options due to the need for individual power connections and heat-resistant materials, which restrict their light output and service life.
Innovation Solution
A linear lighting system featuring a mounting profile with a supply cable and a luminaire profile that allows tool-free electrical connection via contact pins, enabling flexible installation and reduced assembly effort, with a flat cable for efficient power distribution and improved heat dissipation through a metallic base plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fluorescent tubes are used to create linear lighting systems, then sufficient basic brightness can be achieved, but installation work becomes extensive due to individual sockets and power connections for each tube
Solution Approach 1:
Multiple fluorescent tubes are combined into a single integrated lighting unit with a common socket and power connection. The lighting unit comprises a socket holder with multiple sockets arranged to receive multiple tubes, all powered through a single connection point, eliminating the need for individual power connections for each tube.
2Adaptability or versatility
If light-emitting diodes are integrated in plastic hoses, then flexible installation is possible, but heat dissipation becomes insufficient leading to reduced service life
Solution Approach 1:
The lighting unit combines plastic components (socket holder, housing) with metal heat-dissipating elements. The socket holder and associated components are made of metal materials that provide effective heat dissipation pathways, while maintaining the flexibility and ease of installation characteristic of plastic construction.
3Illumination intensity
If light-emitting diodes are arranged on printed circuit boards, then high light output is achieved, but assembly work increases due to individual power connections required
Solution Approach 1:
Multiple LED modules or circuit boards are electrically combined into a single lighting unit that receives power through one common socket and power connection. The internal wiring within the lighting unit distributes power to all LED modules, reducing assembly work by eliminating the need for individual external power connections for each module.
4Area of stationary object
If multiple lighting elements are connected over long distances, then coverage area increases, but cable routing becomes complex and installation effort increases
Solution Approach 1:
The lighting system is segmented into modular lighting units that can be independently installed and later connected. Each lighting unit is a self-contained module with integrated power distribution, allowing flexible placement throughout the coverage area without requiring complex cable routing between individual lighting elements.
