Solution Overview

Problem

Current light sources with adjustable output directionality and shape often compromise on visual aesthetics and create visual clutter, as they require significant structural changes to alter the light beam direction, which is not addressed by existing solutions.

Innovation Solution

A luminaire with pivotally coupled light modules that adjust directionality without altering the spatial profile, using a housing with a coupling structure that allows light modules to pivot about a transversal axis perpendicular to the longitudinal axis, maintaining the luminaire's overall appearance and reducing visual clutter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If light sources are made adjustable in directionality and shape, then lighting versatility is improved, but visual aesthetics and spatial profile consistency deteriorate

Engineering Contradiction:
Improveadjustability of light outputVSAvoidspatial profile consistency
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The luminaire is divided into multiple independent light modules that can be adjusted separately. Each light module contains a light source and optics assembly that can pivot independently relative to the housing, allowing directional adjustment without altering the overall spatial profile of the luminaire. This segmentation enables versatility in light output while maintaining consistent external appearance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A coupling structure serves as an intermediary mechanism between the light modules and the housing. This coupling structure allows the light modules to pivot and adjust their orientation while remaining constrained within the housing boundaries. The intermediary mechanism transmits adjustment motions while preserving the overall spatial profile, resolving the contradiction between adjustability and shape consistency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If light modules are made movable to adjust directionality, then lighting control is improved, but visual clutter increases

Engineering Contradiction:
Improvelighting control capabilityVSAvoidvisual clutter
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The light modules are nested within the housing structure, with adjustment mechanisms integrated into the housing itself. The light modules can pivot within the housing boundaries, and the housing may include transparent or translucent portions that allow the nested structure to be visually appreciated rather than concealed. This nesting approach provides lighting control while minimizing visual clutter by integrating movement within the overall form.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The adjustment mechanism operates in a dimensional space that does not compromise the external appearance. Light modules pivot about axes that allow directional change while maintaining the luminaire's overall spatial profile. The coupling structure enables movement in multiple dimensions while constraining the external dimensions to preserve aesthetic appearance, effectively separating functional adjustment from visual impact.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the luminaire structure is made complex to enable adjustment, then lighting versatility is improved, but device complexity increases

Engineering Contradiction:
Improvelight output adjustmentVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The coupling structure serves multiple functions simultaneously: it provides the pivot mechanism for light module adjustment, maintains the spatial profile of the luminaire, and integrates the adjustment capability into the housing itself. This multi-functionality reduces the need for separate adjustment mechanisms, thereby reducing overall device complexity while maintaining lighting versatility.

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

Solution Approach 2:

The luminaire incorporates dynamic elements in the form of pivotable light modules that can be adjusted during operation. The coupling structure enables these dynamic adjustments while maintaining a relatively simple overall structure. The dynamic capability is achieved through straightforward pivot mechanisms rather than complex actuation systems, balancing versatility with structural simplicity.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention provides a general illumination luminaire comprising one or more adjustable light modules. In particular, the luminaire generally comprises one or more light modules, each one of which comprising one or more light-emitting elements, and optionally comprising a heat sink in thermal contact therewith and output optics for managing light output from the one or more light emitting elements. In general, the light modules are adjustably coupled to the luminaire via a coupling structure that provides one or more adjustment mechanisms for adjusting the orientation of the light modules for adjusting an output directionality of the luminaire, while substantially maintaining the spatial profile of the luminaire.
