Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and maintenance of linear luminaires, particularly those with LED light sources, are complex and costly due to their difficult access points and multi-step installation processes, which complicates equipping large spaces and performing maintenance tasks.
Innovation Solution
A luminaire design featuring a translucent light bar with a front section and mirror-symmetrical side wings, which serves as both primary optics and a carrier for light sources, allowing for simplified assembly and maintenance by reducing the number of installation steps and enabling efficient attachment and detachment of light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If linear luminaires are positioned in difficult-to-access locations such as ceiling centers to illuminate rooms effectively, then illumination performance is improved, but assembly complexity and maintenance cost increase significantly
Solution Approach 1:
The luminaire is divided into modular components: a light bar containing light sources and primary optics, a base profile for mounting, and a separate cover. This segmentation allows the light bar to be pre-assembled and tested independently, then easily installed in difficult-to-access locations without requiring complex on-site assembly of multiple components.
Solution Approach 2:
The light bar is designed to be detachably mounted on the base profile, with the cover subsequently mounted on the base profile to enclose the light bar. This nested arrangement allows compact storage and transportation of components, and enables easy replacement of the light bar module without removing the entire luminaire from its ceiling mounting position.
2Reliability
If traditional multi-step assembly processes are used for linear luminaires with separate base profiles, light bars, and covers, then functional requirements are met, but assembly time and labor cost increase
Solution Approach 1:
The light bar integrates multiple functions into a single component: it serves as the structural carrier, houses the light sources, contains the primary optics for light distribution, and provides mounting interfaces for both the base profile and cover. This merging eliminates the need for separate assembly steps for these components, reducing assembly time while maintaining all necessary functional requirements.
Solution Approach 2:
The light bar is designed as a universal module that can be applied in various luminaire configurations and mounting positions. Its standardized interfaces with the base profile and cover allow it to function reliably across different installation scenarios, reducing the need for custom assembly procedures and enabling faster deployment in large-scale installations.
3Illumination intensity
If separate primary optics and covers are used in traditional linear luminaires, then light distribution control is achieved, but the number of installation steps and maintenance operations increases
Solution Approach 1:
The primary optics are integrated directly into the light bar structure, forming a unified light-generating module. This eliminates the need for separate installation and adjustment of primary optics, as they are pre-positioned and fixed within the light bar during manufacturing. The optics maintain their light distribution control function while becoming part of a single handleable module.
Solution Approach 2:
The light bar is designed as a self-contained module that requires no additional assembly or adjustment of its internal components (light sources, optics, reflectors) during installation. The entire light bar is installed as one unit, and its internal optical system automatically configures itself to provide the required light distribution, eliminating the need for on-site optical alignment or adjustment by installers.

AI summary
A luminaire (7) comprises a base profile (1) and a light bar (2) on which at least one control gear (5) and at least one light source (4) operable by means of the control gear (5) are arranged, the light bar (2) being detachably mounted on the base profile (1). The light bar (2) is made of a translucent material and encloses the at least one light source (4) in its intended direction of emission. The light bar can be used directly as the primary optics of the luminaire. In addition, it can perform its usual function as a carrier for the light-generating components of the luminaire. In this way, the number of components of the luminaire can be kept to a minimum, the overall construction can be relatively simple, and handling, especially during installation and maintenance of the luminaire, is relatively convenient and efficient.
