Multi-directional Light Assembly with Segmented Reflectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light assemblies primarily emit light in a forward direction, failing to provide an expanded field of illumination that could be beneficial for certain end-use applications.
Innovation Solution
The light assembly comprises a housing with a chamber, a light emitting element, a transparent cover, and a reflector, which work together to provide a multi-directional field of illumination of at least 90 degrees, up to 360 degrees, by positioning light emitting elements and reflectors to direct light in various directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional flashlight reflector with rotational symmetry is used, then light is projected efficiently in the forward direction, but the field of illumination is limited and does not provide expanded coverage
Solution Approach 1:
The single conventional reflector is divided into multiple separate reflectors (first reflector, second reflector, third reflector), each oriented at different angles (e.g., 0°, 45°, 90°) to direct light in different directions. This segmentation allows the light assembly to provide both concentrated forward illumination and expanded multi-directional coverage simultaneously.
Solution Approach 2:
The patent transitions from a rotationally symmetric reflector design to an asymmetric configuration with multiple reflectors positioned at specific non-symmetric angles relative to the light source. This asymmetric arrangement enables light to be distributed across a broader field of illumination while maintaining efficient forward projection capability.
2Adaptability or versatility
If multiple light emitting elements and reflectors are added to expand the field of illumination, then coverage is improved, but device complexity increases
Solution Approach 1:
Multiple light emitting elements (first, second, third light emitting elements) and multiple reflectors are combined into a single integrated housing structure. The housing unifies these components into one cohesive assembly that functions as a single unit, reducing the complexity of integration while maintaining the multi-directional illumination capability.
Solution Approach 2:
The light assembly is designed to perform multiple functions simultaneously: it provides concentrated forward illumination through one reflector, expanded side illumination through other reflectors, and overall multi-directional coverage. This multi-functionality is achieved within a single device structure, improving versatility without proportionally increasing complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for a significantly expanded field of illumination, enhancing user visibility in multiple directions, which is particularly useful in applications where a broader range of light is required.
Implementation Method 1
a reflector positioned adjacent the light emitting element... the light emitting element and reflector operate to provide a multi-directional field of illumination
Implementation Method 2
The transparent cover has a convex outer surface to facilitate light transmission in side oriented directions

AI summary
Light assemblies comprise a housing having a chamber, one or more light emitting elements connected with the housing, a transparent cover, and one or more reflectors positioned adjacent the light emitting element. The one or more light emitting elements are interposed between the transparent cover and the one or more reflectors, and the one or more light emitting elements and one or more reflectors operate to provide a multi-directional field of illumination that is 180 degrees or more, e.g., between about 180 to 270 degrees. The transparent cover may have a convex outer surface to facilitate light transmission in side oriented directions. The light assembly may include switches or controls for on/off and/or dimming functions. An example light assembly comprises three light emitting elements in the form of LEDs, and includes three reflectors, wherein the LEDs and reflectors are configured to produce the desired field of illumination.
