Integrated Lighting Fixture for Concealed Fire Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire detection and notification systems in buildings often require separate devices for illumination and fire safety, leading to increased installation and maintenance costs, and lack integrated testing capabilities for their functionality.
Innovation Solution
A combined illumination and fire safety device that includes light emitting devices for ambient lighting, smoke detection, smoke emission, and sound emitting devices, with a controller to transition between normal, alarm, and test modes, and conceal these components within a housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for illumination and fire safety, then each device can be optimized for its specific function, but installation and maintenance costs increase
Solution Approach 1:
The patent combines illumination and fire safety functions into a single integrated device. The housing contains both light emitting devices for illumination and fire safety components (smoke detection, sound emission, alert lighting) that work together in one unit, reducing the number of separate devices needed while maintaining functional reliability
Solution Approach 2:
The integrated device performs multiple functions simultaneously: it provides ambient lighting during normal operation, smoke detection for fire safety, and alarm notification capabilities. This multi-functional approach eliminates the need for separate illumination and fire safety devices, reducing installation and maintenance costs
2Ease of operation
If fire safety components are visible, then occupants can identify them easily, but aesthetic appeal of the room is reduced
Solution Approach 1:
The fire safety components are merged within the same housing as the illumination device. The housing itself serves as the aesthetic element that conceals the functional components, allowing the device to blend into the room's decor while maintaining fire safety functionality
Solution Approach 2:
The housing can be designed in various colors and styles to match different interior decors. The alert light can also change color or intensity to indicate different states, providing visual feedback without compromising the aesthetic appearance of the housing
3Reliability
If integrated testing capabilities are added, then functionality can be verified, but device complexity increases
Solution Approach 1:
The device includes built-in testing capabilities that allow it to self-diagnose and verify its own functionality. The controller can automatically test the smoke detection, alert light, and sound emission components without requiring external testing equipment, ensuring reliability while managing complexity through automation
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
Reduces installation and maintenance costs by integrating fire detection and notification functions into a single device, while ensuring proper functionality through built-in testing, and improving aesthetic appeal by disguising the fire safety components as lighting fixtures.
Implementation Method 1
one or more light emitting devices are coupled to the housing and configured to provide ambient lighting for the room
Implementation Method 2
The one or more fire safety components include a smoke detection system configured to detect a presence of smoke or other airborne medium in the room

AI summary
A device for illumination and fire safety in a room includes a housing, one or more light emitting devices, one or more fire safety components, and a controller. The one or more light emitting devices are coupled to the housing and configured to provide ambient lighting for the room during a normal mode of operation. The one or more fire safety components are coupled to the housing and configured to notify occupants of the room of a fire during an alarm mode of operation. The controller is configured to transition from the normal mode of operation into the alarm mode of operation in response to detecting the fire. The device may include facilities for remote self-testing which may include one or more of a light detector, a sound detector, and a smoke emission system. The device may perform the self-test in a test mode.
