Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art automated luminaires with beam shaping mechanisms are not suitable for optical systems using arrays of discrete emitters like LEDs, as they require internal installation and cannot smoothly adjust the angle of eccentricity of the constrained light beam.
Innovation Solution
A modular beam shaper module with a housing, array of ribbed lenses, and control circuit that can be easily installed or removed from the luminaire, allowing rotation of the beam shaper about the optical axis to adjust the beam's eccentricity, using motors and control signals to achieve continuous adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a prior art beam shaper is installed internally within the luminaire, then the beam shaping function is integrated, but the device cannot be easily installed or removed and is not suitable for arrays of discrete emitters
Solution Approach 1:
The beam shaper is separated from the luminaire body and placed in a detachable holder positioned in the light path. This segmentation allows the beam shaper to be easily installed or removed without modifying the luminaire's internal structure, while still being suitable for arrays of discrete emitters like LEDs.
Solution Approach 2:
A detachable holder serves as an intermediary component between the luminaire and the beam shaper. This intermediary allows the beam shaper to be coupled to the luminaire in a removable manner, enabling easy installation and removal while maintaining adaptability to different emitter arrays.
2Ease of operation
If the beam shaper is fixed in position, then the structure is simple, but the angle of eccentricity of the constrained light beam cannot be adjusted
Solution Approach 1:
The beam shaper holder is made rotatable about the optical axis of the luminaire, transforming the fixed position into a dynamic, adjustable position. This allows the angle of eccentricity of the constrained light beam to be continuously adjusted by rotating the holder to different angular positions, while keeping the mechanical structure relatively simple.

Function Achieved in This Case
Enables flexible and continuous adjustment of the light beam's eccentricity, accommodating various beam shaper designs and allowing easy replacement, enhancing the luminaire's functionality and user convenience.
Implementation Method 1
The beam shaper includes an array of ribbed lenses, each ribbed lens extending across the beam shaper and receiving light from fewer than all of the beams of light
Implementation Method 2
The motor(s) are configured to rotate the beam shaper about an axis of rotation that is coincident with an optical axis of the automated luminaire
