Strip-light luminaire with upward light-emitting modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Continuous-row luminaires primarily designed for downward light emission lack the capability for upward light emission, limiting their applications, and retrofitting with conventional lighting modules is hindered by suspension means acting as obstacles.
Innovation Solution
A continuous-row luminaire with a mounting rail featuring a light source for downward emission and a separately configurable lighting module for upward emission, utilizing holding means and electrical conductor elements for independent power supply, allowing flexible placement and easy installation, even when suspended.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional continuous-row luminaire is retrofitted with a separate continuous-row light on the upper side of the mounting rail to implement indirect lighting, then upward light emission for indirect lighting is achieved, but the suspension means or their attachment elements on the mounting rail form obstacles that prevent satisfactory installation
Solution Approach 1:
The patent combines the downward and upward light-emitting modules into a single integrated continuous-row luminaire unit. The mounting rail accommodates both light sources simultaneously, with the upward-emitting module installed on the upper side and the downward-emitting module on the lower side, eliminating the need for separate retrofitting operations and avoiding conflicts with suspension means.
Solution Approach 2:
The luminaire is divided into separate upward and downward light-emitting modules that can be independently configured and installed. Each module has its own optical system and can be positioned at different locations along the mounting rail, allowing flexible installation that accommodates suspension means while achieving both direct and indirect lighting functions.
2Adaptability or versatility
If the continuous-row luminaire is designed to provide both downward and upward light emission, then lighting application versatility is improved, but the device complexity increases
Solution Approach 1:
The mounting rail is designed as a universal support structure that accommodates both upward and downward light-emitting modules along with suspension means. The rail system provides integrated mechanical support and electrical power distribution to all components, enabling multi-functionality without proportionally increasing complexity.
Solution Approach 2:
Instead of adding upward lighting to an existing downward-lighting luminaire (which would increase complexity), the patent inverts the approach by designing the luminaire from the ground up with both upward and downward capabilities integrated into the core structure. The mounting rail is specifically designed to receive modules oriented in opposite directions, making dual-directional lighting a fundamental feature rather than an add-on.
3Adaptability or versatility
If the lighting module is made separately configurable and independently powered, then adaptability is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
Each light-emitting module is equipped with its own power supply unit, allowing it to operate independently. The modules can be freely positioned along the mounting rail and will automatically receive power through contacts integrated into the rail system, eliminating the need for complex centralized power distribution and simplifying installation and reconfiguration.

Function Achieved in This Case
Enables variably configurable upward light emission for indirect lighting and simplifies handling and installation by allowing the lighting module to be securely and easily attached at any point on the mounting rail, independent of the downward light source's power supply.
Implementation Method 1
a light source which is arranged on the mounting rail and which emits light downwards
Implementation Method 2
at least one lighting module for emitting light upwards
