Luminaire Adjustable Reflector for Dynamic Lighting Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current luminaires lack the ability to adjust lighting profiles effectively, particularly in terms of angle and intensity, which limits their adaptability to different lighting needs.
Innovation Solution
A luminaire design featuring a housing with interior reflective surfaces and an adjustable rotatable reflector that can alter the angular position relative to the front opening, allowing for customizable light emission by blocking or redirecting light through the use of a hinge mechanism and reflective surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a luminaire uses a fixed housing structure with static light emission, then the manufacturing process is simple and device complexity is low, but the adaptability to different lighting needs is poor
Solution Approach 1:
The patent applies the dynamics principle by introducing a rotatable reflector that can change its angular position relative to the light source. This dynamic component allows the luminaire to adjust its lighting profile by redirecting light at different angles, transforming a static lighting system into an adaptable one without requiring multiple separate fixtures.
Solution Approach 2:
The patent implements universality by designing a single luminaire housing that can perform multiple lighting functions through the adjustable reflector. The same basic structure serves different lighting needs by simply rotating the reflector to different positions, making one device universally applicable to various lighting scenarios rather than requiring specialized fixtures for each application.
2Ease of operation
If a luminaire includes an adjustable reflector mechanism, then the lighting profile can be customized, but the device complexity increases
Solution Approach 1:
The adjustable reflector is designed as a rotatable component that can be easily repositioned to change lighting direction. This dynamic adjustment mechanism provides operational flexibility while maintaining a relatively simple overall structure, as it relies on basic rotational movement rather than complex actuation systems.
Solution Approach 2:
The luminaire is segmented into distinct functional components: a fixed housing with interior reflective surfaces and a separate adjustable reflector. This segmentation allows the adjustable component to be independently manipulated for lighting customization while keeping the main housing structure simple and easy to manufacture.
3Illumination intensity
If the housing includes multiple interior reflective surfaces and an adjustable reflector, then light intensity and angle can be controlled, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the functions of multiple reflective surfaces into a unified housing structure with integrated interior reflectivity. Rather than requiring separate adjustable reflector components for each lighting adjustment, the housing itself incorporates reflective surfaces that work in conjunction with a single adjustable reflector, simplifying the manufacturing process while maintaining light control capabilities.
Solution Approach 2:
The housing structure serves multiple functions simultaneously: it provides structural support, incorporates interior reflective surfaces for light redirection, and houses the adjustable reflector mechanism. This multi-functionality reduces the need for separate components, thereby easing manufacturing while achieving precise light intensity and angle control.

AI summary
Disclosed is a luminaire configured to provide for an adjustable lighting profile. The characteristics that define the lighting profile include the angle and intensity of light emitted from the housing of the luminaire. An example luminaire comprises: a housing and a light source positioned within the housing. The housing defines two lateral side openings and a front opening through which light emitted by the light source can escape; the housing includes a plurality of interior reflective surfaces that redirect light emitted by the light source; and the housing includes an adjustable reflector that is rotatably coupled to the housing and used to selectively block at least a portion of the front opening.
