Ceiling Lamp Fireproof Unit for Gap Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable ceiling lamps made of materials like plastic and aluminum alloys are not fireproof and can exacerbate the spread of fire when temperatures exceed 600°C, as they melt and create gaps for flames to spread, compromising both ceiling and room safety.
Innovation Solution
A ceiling lamp with a fireproof unit that includes a heat-resistant material connecting element and a swelling fireproof element between the retention and adjustment units, along with a heat-resistant unit to prevent heat dissipation failure, forming a secure chamber to slow fire spread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional materials (plastic, aluminum alloy) are used for lamp components, then the lamp has good aesthetic appearance and is rust-free, but the lamp cannot withstand high temperatures and melts during fire disasters, compromising fireproof performance
Solution Approach 1:
The patent applies composite materials by combining conventional aesthetic materials (plastic, aluminum alloy) with fire-resistant materials (intumescent coating, high-temperature resistant ceramics). The fire-resistant coating is applied on the surface of conventional lamp components, creating a composite structure that maintains both aesthetic appearance and fire resistance. The intumescent coating expands when exposed to fire, forming a protective char layer that insulates the underlying conventional materials from excessive heat.
2Adaptability or versatility
If space is provided between adjustment element and retention element for lighting angle adjustment, then the lamp achieves multi-angle illumination capability, but the gap allows fire to spread quickly from bottom to top of ceiling
Solution Approach 1:
The patent introduces a fireproof element as an intermediary substance filled in the gap between the adjustment element and retention element. This fireproof material serves as a mediator that maintains the functional space needed for lighting angle adjustment while simultaneously providing fire barrier properties. The fireproof element prevents direct flame propagation through the gap while allowing the mechanical adjustment function to operate.
Solution Approach 2:
The patent utilizes parameter changes of fireproof materials that undergo physical or chemical transformation when exposed to fire. The fireproof element changes its properties (such as expanding volume, forming char layer, or increasing density) in response to heat, thereby dynamically sealing the gap and preventing fire spread while maintaining the structural space for adjustment movement.
3Shape
If lamp components are embedded in ceiling for aesthetic appearance, then the lamp provides good visual integration, but the lamp components can melt and fall off during fire, creating safety hazards and accelerating fire spread
Solution Approach 1:
The patent applies beforehand cushioning by pre-installing fire-resistant support structures and protective coatings on lamp components before they are embedded in the ceiling. These protective measures are in place beforehand to cushion against the thermal shock and mechanical stress of fire. The fire-resistant support structures are designed to maintain structural integrity at high temperatures, preventing component failure and fallout.
Solution Approach 2:
The patent employs composite materials by combining conventional lamp components with fire-resistant materials. The components are constructed as composites where the outer layer or structural core consists of fire-resistant materials (such as high-temperature ceramics, fire-resistant metals, or composite alloys) while maintaining the aesthetic appearance of conventional materials. This composite construction ensures structural stability during fire while preserving visual integration.
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 effectively prevents fire from spreading from the ceiling's bottom to top by sealing gaps and maintaining structural integrity at high temperatures, reducing the risk of fire spreading and ensuring safety during a fire disaster.
Implementation Method 1
The first fireproof element (71) is heated to swell in a high-temperature environment, so that the first fireproof element (71) seals a gap between the retention unit (10) and the adjustment element (20)
Implementation Method 2
a fireproof unit (70) which comprises a first fireproof element (71) provided between a second retention element (12) of a retention unit (10) of the lamp and an adjustment element (20), wherein the first fireproof element (71) is made of heat-swellable material

AI summary
A lamp, suitable to be mounted on a lamp attachment such as a ceiling, comprises a retention unit suitable for fixing the lamp to the lamp attachment, an adjustment element used for adjusting the projecting direction of light beams emitted by a light emitting element disposed at the lamp, a heat dissipation element for dissipating heat, and a heat resistant unit resisting high temperature and difficult to melt. The lamp further comprises a fireproof unit used for reducing the spreading speed of a fire caused by a fire disaster spreading to the outside of the lamp.
