Pendant Luminaire Segmented Light Source for Modular Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pendant lamps face challenges in easy assembly and disassembly, particularly when replacing light sources or control gear, which can affect indirect lighting properties, and safety concerns arise from accidental electrical contact.
Innovation Solution
A pendant lamp design featuring a light source with multiple longitudinal sections arranged in a structural unit, allowing for easy separation and reassembly without detaching the lamp, with a screw connection for mechanical and electrical grounding, and a plug connection for electrical ease, along with profile elements and connecting elements for modular construction and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the light source is designed as a single integrated unit, then the structural complexity is reduced, but the ease of repair and replacement deteriorates
Solution Approach 1:
The light source is divided into multiple sections (first section, second section, third section) arranged along the longitudinal axis, where each section can be independently replaced. The second section is positioned at a higher level and can be accessed separately from the first and third sections, enabling modular replacement without replacing the entire light source assembly.
2Object-affected harmful factors
If the pendant lamp requires complete disassembly for light source replacement, then safety from electrical contact is improved, but the ease of operation deteriorates
Solution Approach 1:
The light source is segmented into accessible sections that can be removed independently. The second section, positioned at higher level, can be accessed and replaced by tilting the pendant lamp without requiring complete disassembly, thus maintaining safety while improving operational ease.
Solution Approach 2:
The pendant lamp incorporates a tiltable design that allows dynamic adjustment of the light source sections. By tilting the lamp, the second section becomes accessible for replacement without requiring the lamp to be fully disassembled or removed from its installation position.
3Manufacturing precision
If the second section is positioned at the same level as the first section, then the manufacturing precision is simplified, but the adaptability deteriorates
Solution Approach 1:
The light source employs an asymmetric vertical arrangement where the second section is positioned at a higher level than the first and third sections. This asymmetric positioning creates accessible space underneath the second section for installing operating devices such as control gear or dimming controls, enhancing the pendant lamp's versatility without compromising manufacturing feasibility.
