Coordinated Prism Control for Automated Luminaire Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated luminaires are limited to using a single prism in the optical effect chain, which restricts the ability to create complex and dynamic lighting effects, as they cannot simultaneously introduce and coordinate multiple prisms for concatenated effects.
Innovation Solution
A system that allows for the simultaneous insertion and coordinated positioning and rotation of multiple prisms within the optical path of an automated luminaire, using motorized prism arms and sensors to control the prisms' orientation and rotation, enabling the creation of complex and dynamic lighting effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single prism is used in the optical effect chain, then the system structure remains simple, but the ability to create complex and dynamic lighting effects is restricted
Solution Approach 1:
The patent divides the single prism function into multiple separate prism units (first prism, second prism, etc.) that can be independently controlled. Each prism is mounted on its own motorized arm with independent positioning and rotation capabilities, allowing complex lighting effects to be achieved through coordinated operation of multiple segmented prism elements rather than a single complex prism.
Solution Approach 2:
The patent implements a hierarchical control structure where multiple prism systems are nested within the luminaire's optical path. The first prism system, second prism system, and additional prism systems are arranged in sequence along the light beam path, with each system nested within the overall luminaire structure. This nested arrangement allows compact integration of multiple prism functions while maintaining independent control of each prism unit.
2Adaptability or versatility
If multiple prisms are introduced simultaneously, then complex and dynamic lighting effects can be produced, but the coordination and control of prism positions and rotations becomes more difficult
Solution Approach 1:
The patent incorporates sensors (such as Hall effect sensors or encoders) on each motorized prism arm to provide feedback on the position and rotation angle of each prism. This feedback is fed to the control system, which processes the information and adjusts the motor commands to achieve precise coordinated positioning and rotation of multiple prisms. The feedback mechanism enables accurate coordination control despite the complexity of managing multiple independent prism units.
Solution Approach 2:
The patent employs universal motorized prism arms that can be replicated and standardized across multiple prism positions. Each prism arm uses the same motorized mechanism, sensor type, and control interface, creating a universal module that can be installed in multiple locations. This universality simplifies operation because the control system uses consistent commands and parameters for all prism units, making coordination easier despite the increased number of elements.
3Manufacturing precision
If motorized prism arms with sensors are used to control prism orientation and rotation, then precise coordinated effects are achieved, but the device complexity increases
Solution Approach 1:
The patent segments the motorized control system into independent, modular prism arms, where each arm is a self-contained unit with its own motor, sensor, and control electronics. This segmentation allows each motorized arm to be manufactured and tested as a separate module, simplifying the overall manufacturing process despite the increased precision requirements. The modular approach also allows for easier maintenance and replacement of individual precision components without affecting other prism units.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the production of new dynamic lighting effects by allowing multiple prisms to be inserted and rotated within the light beam, producing complex and coordinated effects that would not be possible with single-prism systems, enhancing the versatility and creativity in lighting applications.
Implementation Method 1
An optical effect that is commonly used in prior art automated luminaires is often referred to as a prism. This is typically a glass or plastic device placed at a point in the optical train such that it converts a single image produced by the beam color, size, shape, and pattern optical systems into multiple beams for display.
