Adjustable LED Reflector Fixture for Dynamic Light Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures lack flexibility in adjusting light emission angles and are cumbersome for replacing multiple light sources, as they often require individual replacement of light sources and do not allow for easy access or adjustment.
Innovation Solution
A light fixture design that includes movable reflector members to adjust light emission angles and allows quick access to light emitting devices for replacement, featuring a modular structure with adjustable reflectors and a detachable lens for easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fixed reflectors are used to focus light, then light can be focused onto the desired area, but the light emission angle cannot be adjusted
Solution Approach 1:
The reflector members are made movable relative to the light emitting device, allowing the light emission angle to be dynamically adjusted. The reflectors can be positioned at different angles to change the direction and spread of reflected light, transforming a static lighting system into an adjustable one that adapts to different illumination requirements.
2Illumination intensity
If multiple light sources are installed in the fixture, then the lighting coverage is improved, but the replacement process becomes time-consuming
Solution Approach 1:
Multiple light emitting devices are combined into a single modular light module assembly. This module can be removed and replaced as one unit, allowing all light sources within the module to be replaced simultaneously rather than individually. The modular design integrates the light sources, reflectors, and housing into a single replaceable component, dramatically reducing maintenance time.
Solution Approach 2:
The lighting fixture is segmented into modular components, with the light module being a distinct replaceable unit. This segmentation allows the light module to be independently removed from the fixture housing, enabling quick replacement of multiple light sources without disassembling the entire fixture or handling each light source separately.
3Stability of the object's composition
If the light module is securely mounted, then the structural stability is improved, but the access for replacement becomes difficult
Solution Approach 1:
The mounting mechanism uses removable fasteners that provide secure attachment during normal operation but can be quickly released when maintenance is needed. The fasteners transition from a locked state that ensures structural stability to an unlocked state that enables easy removal, allowing the light module to be firmly mounted yet accessible for replacement.

AI summary
Provided is a light fixture having a first elongate body defining a mounting surface. A light module is disposed adjacent the mounting surface and includes a module body and a plurality of light emitting devices disposed on the mounting body. The light emitting device defines an emitting axis about which light is emitted. The fixture further includes a first reflector member and a second reflector member disposed on opposed sides of the emitting axis for reflecting light emanated by the light emitting devices. The first reflector member and the second reflector member are pivotable to vary the angle at which light is emitted from the light fixture.
