Adjustable Cover Mechanism for LED Lighting Glare Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices with semiconductor light sources, such as LEDs, are limited in preventing glare and maximizing their lighting potential due to fixed positions and inability to control light effects effectively.
Innovation Solution
A lighting device featuring a surface-mountable elongated carrier with adjustable covers that can be positioned relative to a surface, allowing the light source to be controlled to prevent glare and adjust light effects, including cut-off angles, regardless of the device's position, using a mechanism that enables translational and rotational movement of the adjustable cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fixed-position lighting device is used, then the structure is simple, but the ability to prevent glare and control light effects is limited
Solution Approach 1:
The patent applies the dynamics principle by making the cover movable relative to the carrier through a mechanism that enables translational and rotational movement. This allows the cover to dynamically adjust its position and orientation to control light effects and prevent glare from semiconductor light sources, transforming a static structure into an adaptive system that responds to different mounting positions and lighting requirements
2Adaptability or versatility
If the lighting device is mounted in different positions, then application versatility is improved, but glare control becomes difficult
Solution Approach 1:
The movable cover mechanism enables the lighting device to maintain effective glare control regardless of its mounting position. The cover can translate and rotate to adjust the cut-off angle and light distribution, allowing the device to adapt to various mounting orientations while consistently preventing glare and controlling light effects in retail, entertainment, and hospitality applications
3Adaptability or versatility
If a movable cover is added to control light effects, then lighting versatility is improved, but device complexity increases
Solution Approach 1:
The patent merges the cover and carrier into an integrated assembly where the cover is connected to the carrier through a combined translational and rotational mechanism. This integration allows the cover to perform multiple functions - controlling light effects, adjusting cut-off angles, and preventing glare - while sharing structural elements with the carrier, thereby achieving versatile light control with relatively controlled complexity
