Adjustable Reflector Panels for Directional Light Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems, such as fluorescent and incandescent systems, emit light omnidirectionally, resulting in inefficient light concentration and significant light energy loss away from the subject area, particularly in applications like indoor growing systems where focused light is needed for plant growth.
Innovation Solution
A light enhancing system comprising a light housing with extendable and adjustable reflector panels and flexible arms, including a swivel joint mount that rotates in response to airflow, allowing for improved light reflection and concentration onto a target area by adjusting the angle of reflection and leveraging air circulation for wider coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting systems emit light omnidirectionally, then light coverage area is maximized, but light concentration onto subject area becomes inefficient
Solution Approach 1:
The lighting system is segmented into multiple adjustable reflector panels that can be independently positioned. Each panel captures light from specific directions and redirects it toward the subject area, thereby concentrating light where needed while minimizing omnidirectional energy loss.
Solution Approach 2:
The reflector panels are made dynamically adjustable through mechanical linkages and positioning mechanisms. This allows the system to adapt the reflection angles in real-time to optimize light concentration onto the subject area, transforming static omnidirectional emission into dynamic directional control.
2Illumination intensity
If reflective internal surfaces are added to bounce light back toward subject area, then light concentration improves, but device complexity increases
Solution Approach 1:
Instead of using a single complex housing with integrated reflective surfaces, the invention segments the reflection function into separate, modular reflector panels. These panels can be independently adjusted and positioned, simplifying the overall housing structure while maintaining effective light reflection.
Solution Approach 2:
The reflector panels act as intermediary elements between the light source and the subject area. Rather than incorporating reflection directly into the housing structure, these separate panels mediate the light path, allowing for simpler housing design while achieving the same light concentration effect.
3Ease of manufacture
If static reflective surfaces are used, then manufacturing is simplified, but adaptability to different subject areas is reduced
Solution Approach 1:
The system transitions from static to dynamic reflector positioning. Each reflector panel can be independently adjusted to different angles and positions, allowing the same manufactured components to adapt to various subject areas and lighting requirements without requiring custom manufacturing for each application.

The system effectively increases light reflection onto a subject area, reduces energy waste, and enhances plant growth by capturing stray light without additional heat, thereby increasing yield in gardens and greenhouses.
Implementation Method 1
a swivel joint mount coupling the first flexible arm and the second flexible arm to the light housing, wherein the swivel joint mount is configured to rotate freely about an axis transverse to the first or second flexible arm in response to airflow impacting the second reflector panel or the third reflector panel
Implementation Method 2
a first reflector panel extending from the light housing... a second reflector panel... a third reflector panel... configured to reflect light from the light source
Data Source
AI summary
A light enhancing system is disclosed which extends the available area for capturing light from a source and adjustably increases the light concentration on a subject being lit. Embodiments may be beneficial to applications including grow lighting. One or more reflector panels may be detachably coupled to a lighting unit by a quick-connect fastener on the end of a flexible arm. Examples of quick-connect fasteners include threaded ends, press-fit ends, and magnetic ends. In some embodiments, the reflector panel may be retrofit onto a conventional lighting unit.
