Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing low-profile stage luminaires are often bulky, hot, and obstructive, and they pose challenges in managing cables around the stage, which can be unsightly, prone to damage, and hazardous.
Innovation Solution
The luminaire design features an elongated housing with LEDs that produce less heat and consume power efficiently, a low-profile design that minimizes obstruction, and a cable cavity to house electrical cabling securely, along with adjustable light shields and maintenance access panels for easy installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional stage luminaires are used, then lighting function is provided, but the luminaire becomes bulky and obstructive
Solution Approach 1:
The luminaire is divided into multiple functional modules including a housing module, light emitter module, cable management module, and control module. This segmentation allows each component to be optimized independently, resulting in a compact overall structure that provides full lighting functionality without bulk
Solution Approach 2:
The cable management system is nested within the housing structure, with cables routed through internal channels and stored in dedicated compartments. The control module is integrated into the housing rather than being external. This nesting eliminates the need for separate cable trays and external control boxes, significantly reducing the luminaire's overall volume
2Illumination intensity
If traditional luminaires are used, then lighting is provided, but heat generation becomes excessive
Solution Approach 1:
Traditional incandescent or halogen lighting systems are replaced with LED light emitters. This substitution eliminates the need for large reflectors, lenses, and heat dissipation structures associated with thermal lighting systems. LEDs provide equivalent or superior illumination intensity while generating minimal heat, allowing for a compact luminaire design without excessive temperature rise
Solution Approach 2:
The light generation mechanism changes from thermal radiation to electroluminescence. This parameter change in the physical process of light generation fundamentally reduces heat output while maintaining or improving illumination intensity, directly resolving the contradiction between light output and heat generation
3Use of energy by stationary object
If cables are managed externally, then power and control are provided, but cables become unsightly and hazardous
Solution Approach 1:
Cables are extracted from the external environment and routed through internal channels within the housing. Power and control signals are delivered through these internal pathways, eliminating the need for exposed cables on stage. This extraction removes the harmful factors associated with external cables (trip hazards, damage from equipment, unsightly appearance) while maintaining full power and control functionality
Solution Approach 2:
The housing structure serves as an intermediary that contains and protects the cable routing system. Internal cable channels and protective conduits act as intermediaries between the power source and light emitters, shielding cables from external hazards while maintaining electrical connectivity. This intermediary structure eliminates cable hazards while preserving energy delivery function

AI summary
A luminaire includes an elongated housing having a long axis, a plurality of light emitters extending in a direction of the long axis, a first light shield rotatably coupled to a base of the luminaire and configured to rotate about a first axis parallel to the long axis, and a second light shield rotatably coupled to the base of the luminaire and configured to rotate about a second axis parallel to the long axis. The first light shield and the second light shield are configured to physically couple to form a combined light shield that is configured to block light emitted by the plurality of light emitters.
