Solution Overview

Problem

Conventional lighting systems require numerous spotlights to effectively illuminate elongated spaces, leading to inefficient light distribution with unwanted illumination of certain areas and failure to meet aesthetic requirements.

Innovation Solution

A modular luminaire system with light segments that can be inserted into a base body, each emitting light in a directed manner with predefined radiation characteristics, allowing for flexible and targeted illumination by combining segments with different radiation characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If individual ceiling spotlights are used to illuminate elongated spaces, then the illumination coverage can be extended, but the number of spotlights required increases and light distribution becomes inefficient

Engineering Contradiction:
Improveillumination coverage areaVSAvoidnumber of spotlights
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The luminaire is divided into multiple independently controllable light segments, each with its own optical component (reflector or lens). This segmentation allows each segment to illuminate a specific zone within the elongated space, achieving comprehensive coverage while reducing the total number of luminaires needed compared to conventional spotlights.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The luminaire base body is designed to accommodate multiple types of light segments with different radiation patterns (spot, flood, accent). This multi-functionality allows a single luminaire to perform various lighting tasks that would traditionally require multiple different lighting fixtures, thereby reducing the overall quantity of lighting devices needed.

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

2Area of stationary object

If conventional spotlights are used, then illumination coverage can be achieved, but light falls on areas not intended to be illuminated and other areas are less well lit than desired

Engineering Contradiction:
Improveillumination coverage areaVSAvoidlight distribution precision
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

Each light segment is equipped with a specific optical component (reflector or lens) tailored to its intended function. For example, spot segments have reflectors for focused beams, while flood segments have lenses for wide distribution. This local optimization of optical properties ensures that each segment illuminates only its intended target area with the desired precision, avoiding light spill onto unintended areas.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The luminaire allows for dynamic configuration by enabling the insertion and removal of different light segments with varying radiation patterns. This dynamic adaptability allows the lighting system to be optimized for different lighting scenarios and spatial requirements, achieving precise light distribution that adapts to specific illumination needs rather than using a fixed, generic pattern.

Inventive Principle:
Principle #15Dynamics

3Illumination intensity

If conventional lighting solutions are used, then basic illumination can be provided, but aesthetic requirements are not fully met in all situations

Engineering Contradiction:
Improvebasic illumination levelVSAvoidaesthetic lighting flexibility
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The luminaire enables dynamic reconfiguration of lighting effects by allowing users to insert and remove different light segments with varying radiation patterns. This dynamic capability allows the same luminaire base body to produce diverse aesthetic lighting effects (spotlighting, flooding, accent lighting) depending on which segments are installed, providing adaptability to different aesthetic requirements without compromising basic illumination.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different light segments provide locally optimized lighting qualities for specific aesthetic purposes. For example, certain segments are designed to create dramatic accent lighting on architectural features, while others provide soft ambient illumination. This local differentiation of lighting quality within a single luminaire enables fulfillment of diverse aesthetic requirements that would traditionally require multiple specialized fixtures.

Inventive Principle:
Principle #3Local quality
