Removable Optical Structure Luminaire Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaires lack the ability for users to easily change decorative elements and optical structures to adapt to different lighting requirements, leading to unsuitable lighting for changing room functions.
Innovation Solution
A luminaire design featuring a light engine with a removable optical structure and decorative element, where the optical structure has a protruding annular portion for supporting the decorative element, allowing users to change the light output characteristics by selecting different optical structures and decorative elements to suit specific lighting needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the luminaire uses fixed optical structures and decorative elements, then the manufacturing cost and structural complexity are reduced, but the adaptability to different lighting requirements deteriorates
Solution Approach 1:
The luminaire is divided into separable modules: a base unit containing the light engine and removable optical structures. The optical structure includes a decorative element, diffuser, and lens that can be detached and replaced independently, allowing users to reconfigure lighting patterns without replacing the entire luminaire.
Solution Approach 2:
The base unit is designed as a universal platform that can accommodate multiple different optical structures through standardized mounting interfaces. This allows a single base unit to serve multiple lighting functions (spot, flood, ambient) by simply changing the optical structure attachment.
2Adaptability or versatility
If the luminaire allows easy replacement of decorative elements and optical structures, then the adaptability to changing room functions is improved, but the device complexity and number of components increases
Solution Approach 1:
The decorative element, diffuser, and lens are merged into a single integrated optical structure assembly. This reduces the number of separate components users must handle and replace, while still providing the flexibility to change lighting characteristics by swapping the entire assembly as one unit.
Solution Approach 2:
The optical structure is designed with nested components where the decorative element surrounds the diffuser, which in turn surrounds the lens. This nested arrangement allows compact packaging and simplifies the replacement process, as the entire nested assembly can be removed and replaced as a single unit.
3Ease of operation
If the optical structure is permanently integrated with the housing, then the manufacturing process is simplified, but the ease of operation for changing lighting patterns deteriorates
Solution Approach 1:
Multiple optical structures are pre-manufactured with standardized mounting features that match corresponding receptacles on the base unit. This preliminary preparation of standardized interfaces enables quick tool-free installation and removal, making the luminaire easy to reconfigure without requiring complex assembly procedures during manufacturing.
4Ease of repair
If the luminaire is designed as a single integrated unit, then the structural stability is improved, but the ease of repair and component replacement deteriorates
Solution Approach 1:
The optical structure is extracted as a separate removable component from the base unit, allowing it to be independently replaced without affecting the structural integrity or other components of the luminaire. The standardized mounting interface ensures stable connection during use while enabling easy removal for replacement or repair.
