Solution Overview
Problem
Existing lighting apparatuses using light-emitting diodes as a light source face difficulties in installation due to weight, complexity of lead wires, and potential for electrical interference, leading to insecure and cumbersome installation processes.
Innovation Solution
A luminaire design featuring a light-emitting unit with a base substrate, reflector, and terminal unit, supported by a main body frame and a support frame with a groove-shaped receiving place, allowing for easy assembly and secure attachment to a ceiling, with a simplified lead wire connection system that minimizes interference and exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a large number of light-emitting diodes are used in a large-size lighting apparatus, then the lighting coverage and illumination intensity are improved, but the lead wires become complex and are liable to interfere with each other, increasing device complexity and installation difficulty
Solution Approach 1:
The lighting apparatus is divided into multiple independently controllable light-emitting units, each with its own lead wire connections. This segmentation allows each unit to be wired separately, reducing overall wire complexity while maintaining large-scale illumination coverage through modular arrangement.
Solution Approach 2:
The patent transitions from planar LED arrangements to three-dimensional spatial configurations of light-emitting units. By arranging units in multiple dimensions and levels, the system achieves extensive lighting coverage without proportionally increasing lead wire complexity, as units can be positioned to share connection pathways.
2Area of stationary object
If the lighting apparatus is installed on a ceiling in high places, then the lighting coverage area is improved, but the installation operation becomes difficult and requires complex fixing means
Solution Approach 1:
The lighting apparatus is divided into multiple detachable light-emitting units that can be installed separately on the ceiling. This segmentation allows workers to install smaller, lighter units individually at high locations without needing to handle the entire large apparatus, significantly improving installation safety and ease of operation while achieving extensive coverage through coordinated arrangement of multiple units.
3Ease of operation
If a common fixing method using spring elasticity is used to attach the main unit to the ceiling edge, then the installation process is simplified, but the apparatus cannot be securely installed when the equipment is very heavy
Solution Approach 1:
The apparatus is divided into multiple separate light-emitting units, each weighing less than the total apparatus. These smaller units can be securely attached to the ceiling using simple spring-based fixing methods, as the reduced weight of individual units allows the spring elasticity to provide sufficient holding force, thereby maintaining both installation simplicity and security.
4Productivity
If a large number of lead wires are connected in vertical and horizontal directions, then the light-emitting diodes can be powered, but the electrical wires and lead wires are exposed to the rear side and disturb the installation
Solution Approach 1:
The lead wires are routed through the internal structures of the light-emitting units and along the support frames, nesting the wiring within the apparatus framework rather than leaving it exposed. This nesting approach maintains all necessary electrical connections while keeping the wiring concealed and non-interfering with installation and maintenance operations.
