Folded Light Source Carrier for Omnidirectional Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination devices struggle to provide omnidirectional light distribution while being easy to assemble and manufacture, as they often require complex configurations and multiple components.
Innovation Solution
An illumination device comprising at least two light sources coupled to different portions of a carrier, which is partially enclosed by an envelope, allowing the carrier to be bent or folded to direct light in multiple directions, thereby simplifying assembly and reducing the number of components needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple carriers are used to support light sources on different sides, then uniform light distribution is achieved, but device complexity and assembly difficulty increase
Solution Approach 1:
The single carrier is divided into multiple portions (first portion, second portion, third portion) that are spatially separated and oriented to face different directions. Each portion supports light sources that emit light in specific directions, collectively achieving omnidirectional illumination while maintaining a single integrated carrier structure.
Solution Approach 2:
The carrier transitions from a planar two-dimensional structure to a three-dimensional folded structure with multiple portions extending in different spatial directions. This dimensional transformation allows light sources on a single carrier to emit light in multiple directions (upward, downward, sideways) simultaneously, achieving omnidirectional illumination without requiring multiple separate carriers.
2Illumination intensity
If multiple separate components are used to achieve omnidirectional illumination, then light distribution is improved, but ease of manufacture deteriorates
Solution Approach 1:
Multiple carrier portions that would traditionally be separate components are merged into a single integrated carrier structure. The first, second, and third portions are electrically connected and mechanically integrated, allowing all light sources to be mounted and connected in a single manufacturing process rather than requiring assembly of multiple separate carrier assemblies.
Solution Approach 2:
The single carrier performs multiple functions simultaneously: it provides mechanical support for light sources, electrical connections between light sources, structural framework for the illumination device, and thermal management pathways. This multi-functionality reduces the total component count and simplifies manufacturing while achieving omnidirectional illumination.
3Ease of operation
If a single carrier is used with light sources on one side only, then ease of assembly is improved, but illumination directionality is limited
Solution Approach 1:
The carrier is folded into a three-dimensional structure with portions extending in multiple spatial directions (upward, downward, sideways). This allows light sources mounted on the single-sided carrier to emit light in multiple directions simultaneously, achieving omnidirectional illumination while maintaining the assembly simplicity of single-sided mounting.
Solution Approach 2:
The carrier structure is designed with flexible or foldable portions that can be arranged in different spatial configurations. This dynamic arrangement allows the same single carrier to adapt its orientation and shape to direct light in multiple directions, providing versatility in light emission patterns while maintaining ease of assembly through single-sided mounting.

AI summary
An illumination device includes a carrier, at least two light sources mounted on a first side of a carrier, and an envelope at least partially enclosing light sources and the carrier. At least one of the light sources is mounted on a portion of the carrier and at least another one of the light sources is mounted on a different portion of the carrier, and the carrier is folded such that the second side of the first portion of the carrier at least partially faces the second side of the second portion of the carrier.
