Floating Emergency Light Mounting in Recessed Luminaire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recessed ceiling lamps with emergency lighting elements suffer from an unsightly gap between the emergency light eye and the cover elements due to thermal expansion differences, affecting the external appearance and stability during transport.
Innovation Solution
A floating mounting system for the emergency light element, where the holder is designed to keep the element parallel to the frame, allowing for a smaller gap and central alignment, preventing the element from falling out when tilted, and using a lamination to cover any remaining space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the recess is dimensioned generously to accommodate thermal expansion of the cover element, then the cover element does not collide with the emergency light element when heated, but a large gap is formed between the emergency light element and the recess, adversely affecting the external appearance
Solution Approach 1:
The patent applies the dynamics principle by making the emergency light element movable within the recess through a floating mounting system. The element can move dynamically to accommodate thermal expansion of the cover element while maintaining a consistent appearance. The holder allows the emergency light element to adjust its position within the recess, eliminating the need for excessive clearance while preventing collision during thermal expansion.
Solution Approach 2:
The patent changes the mounting parameters from fixed to floating, allowing the emergency light element to adjust its position within the recess. This parameter change enables the system to accommodate thermal expansion while maintaining minimal gap dimensions for aesthetic purposes. The floating mounting system transforms the rigid fixed-position parameter into a flexible adjustable parameter.
2Ease of manufacture
If the emergency light element is simply inserted into the recess, then the installation is simple, but the emergency light element may fall out when the lamp is tilted during transport
Solution Approach 1:
The patent introduces a holder as an intermediary component between the emergency light element and the recess. This holder serves as a mediator that provides both the simple insertion capability and the retention function during transport. The holder acts as an intermediate structure that simplifies installation while ensuring the element remains securely positioned and cannot fall out when the lamp is tilted.
3Shape
If the emergency light element is centrally aligned within the recess, then the external appearance is improved, but the element may collide with the recess boundaries when the cover element expands thermally
Solution Approach 1:
The floating mounting system enables the emergency light element to move dynamically within the recess in response to thermal expansion forces. This dynamic capability allows the element to maintain central alignment for aesthetic purposes while having the freedom to shift position if thermal expansion pushes it toward the boundaries, thus resolving the contradiction between appearance and thermal tolerance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution minimizes the gap between the emergency light element and the recess, enhancing the lamp's external appearance and ensuring the element remains securely attached, even when tilted.
Implementation Method 1
The light source of the emergency light eye is an LED light source
Implementation Method 2
The plate-like elements that form the cover element 200 are made of plastic. Therefore, they expand accordingly when heated.
