Solution Overview

Problem

Existing luminaire systems with light emitting diodes (LEDs) lack the ability to adjust individual LEDs independently within a light curtain, limiting the precision and versatility in directing light beams.

Innovation Solution

The method allows for both synchronized and independent movement of LEDs in a luminaire system, enabling each light-emitting module to be individually adjusted for color, beam angle, and position through motorized mechanisms controlled by a data link, allowing for global tilting and panning motions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If all light emitters in the curtain are moved together in synchronized motion, then the curtain can be directed as desired, but individual light emitters cannot be adjusted independently to create converging or diverging curtains

Engineering Contradiction:
Improvelight beam shaping capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The light curtain is divided into individually controllable segments (light emitters), each capable of independent movement. This segmentation allows different parts of the curtain to be adjusted independently, enabling converging or diverging beam patterns while maintaining overall curtain direction control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from static or globally synchronized emitter positions to dynamically adjustable individual emitter positions. Each emitter can be independently positioned along its optical axis, allowing the curtain to adapt its shape and direction in real-time based on lighting requirements.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If individual light emitters are adjusted independently, then precision in directing light beams is improved, but the device complexity increases

Engineering Contradiction:
Improvelight direction precisionVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Each light emitter is equipped with its own adjustment mechanism, allowing local control of beam direction and position. This local quality approach enables precise individual emitter adjustment without requiring complex centralized control, as each emitter operates independently within its own control zone.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent replaces complex mechanical adjustment systems with motorized mechanisms controlled by data links. This substitution reduces mechanical complexity while maintaining or improving precision, as electronic control provides finer adjustment resolution and easier programmability compared to pure mechanical systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple colors of LEDs are used with separate intensity controls, then color mixing capability is improved, but the device complexity increases

Engineering Contradiction:
Improvecolor mixing capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each light emitter is designed as a multi-functional unit capable of producing multiple colors through combinations of different LED types (red, green, blue, white). This universal emitter design consolidates what would otherwise require separate single-color emitters, reducing overall system complexity while maintaining full color mixing capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple LED types are combined within each light emitter housing, allowing color mixing to occur at the emitter level rather than requiring separate control systems for each color. This merging approach simplifies the control architecture by integrating color control functions directly into the emitter units.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Described is a method for controlling the movement of LED devices in luminaires, specifically to a method relating to allowing both synchronized and independent pan and tilt movement of LED light modules in a light curtain. The LEDs may be mounted in a plurality of modules. The modules may be in a linear arrangement. The LEDs may be mounted in a plurality of modules that are arrayed in a two dimensional array. The modules in the linear arrangement or in the two dimensional array may be mounted in groups forming modular group assemblies where modular group assembly are independently articulated to pan and/or tilt the modules mounted thereon independent of other modular group assemblies.
