Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED projectors lack the ability to easily and simply orient the direction of individual LEDs' light beams, limiting user control over the shape and form of the projected light beam.
Innovation Solution
The development of an asymmetrical reflector that can be rotated about a vertical axis to direct and scatter light beams from LEDs, allowing for customizable light beam orientation and formation by constructing the reflector using geometrically defined surfaces such as paraboloids and ellipsoids, enabling precise control over the diffraction and interference patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a reflector is constructed through rotational solids, then the reflector can efficiently direct light, but the direction of the luminous flux of individual LEDs cannot be oriented
Solution Approach 1:
The invention divides the reflector system into individual directional reflectors for each LED, allowing independent orientation of each light source. This segmentation enables control over the direction of luminous flux from each LED while maintaining efficient light direction through the reflector geometry.
Solution Approach 2:
The invention employs asymmetrical reflector designs that are not constructed through simple rotational solids, allowing the reflectors to direct light in specific non-uniform patterns. This asymmetry enables precise control over the orientation of light beams while maintaining efficient light direction.
2Adaptability or versatility
If individual LED light beam orientation is enabled, then user control over light beam form is improved, but the device complexity increases
Solution Approach 1:
The invention incorporates rotatable mounting mechanisms that allow the directional reflectors to be dynamically adjusted to different orientations. This dynamic capability enables users to control the form and direction of light beams by rotating individual reflectors, providing adaptability without requiring complex fixed structures for each possible orientation.
