Solution Overview
Problem
Existing light band luminaires face issues with direct heat transfer between the control unit and light source plate, leading to disrupted functionality due to inadequate heat dissipation.
Innovation Solution
A rectilinear and longitudinally extending luminaire design featuring an elongated U-shaped support profile with a thermal insulation space between the light interior and profile interior, utilizing a device carrier with a light-emitting base and optics cover to minimize direct heat transfer, and incorporating retaining clips and seals for enhanced heat dissipation and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the control unit and light source plate are placed in direct contact within the support profile, then the structural complexity is reduced and assembly is simplified, but heat transfer between components increases and functionality is impaired
Solution Approach 1:
The device carrier is divided into distinct functional zones: a light-emitting base for mounting light sources and an electronics compartment for the control unit, separated by a partition wall. This segmentation prevents direct thermal contact between heat-generating light sources and temperature-sensitive electronics while maintaining structural integrity and simplifying assembly.
2Temperature
If heat dissipation structures are added to the luminaire, then heat dissipation performance is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The partition wall serving as a thermal barrier is simultaneously designed to provide structural support for mounting the light source plate. The electronics compartment base integrates heat dissipation fins directly into the housing structure. This merging of multiple functions into single components improves heat dissipation without significantly increasing manufacturing complexity.
3Volume of moving object
If the light source plate is positioned close to the support profile for compact design, then the luminaire size is reduced, but direct heat transfer to the profile increases and disrupts functionality
Solution Approach 1:
The light-emitting base and electronics compartment are nested within the U-shaped support profile, with the partition wall creating a thermal barrier layer between the light sources and the profile. This nested arrangement maintains a compact overall size while preventing harmful thermal transfer to the support structure through the intermediate partition wall.

AI summary
The invention relates to a linear luminaire (1) extending in the longitudinal direction (4) for a continuous light strip. The luminaire (1) has a support profile (2) and a gear tray (3) which is positively locked to the support profile (2). The gear tray (3) closes the support profile (2) with a profile closing base (5), thereby forming a profile interior (6) within the support profile (2). The luminaire (1) further comprises at least one elongated optical cover (7) which is fixed to the gear tray (3). The at least one optical cover (7) closes the gear tray (3), thereby forming a carrier interior (9) within the gear tray (3). The luminaire (1) also comprises at least one elongated light-emitting mounting plate (11) with several light sources (12), which is fixed within the carrier interior (9) of the gear tray (3).According to the invention, the device carrier (3) has a light support base (10) which is arranged parallel to and spaced apart from the profile closing base (5) and extends in the longitudinal direction (4). The light support base (10) divides the carrier interior (9) into a light interior (9a) with the at least one light support plate (11) and a thermal insulation space (9b) which is arranged in the longitudinal direction (4) between the profile interior (6) and the light interior (9a).
