Networked LED Light Bulb Alarm with Voice Silencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smoke and carbon monoxide detectors lack integration with lighting systems, leading to separate devices that do not provide simultaneous illumination and alarm signaling, and often require battery replacement, causing annoyance and safety concerns, especially for the elderly or disabled.
Innovation Solution
A networked LED light bulb system that incorporates smoke, carbon monoxide, and gas detectors, using a rechargeable battery to power both lighting and detection circuits, providing audible and visual alarms through colored LED strobes, and featuring a silencing circuit that responds to voice commands and RF communication for networked alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional smoke and carbon monoxide detectors are used separately from lighting systems, then detection functionality is provided, but device complexity increases and ease of operation deteriorates due to multiple separate devices
Solution Approach 1:
The patent combines smoke detection, carbon monoxide detection, and lighting functions into a single integrated LED light bulb apparatus. The detector means, light emitting means, and alarm means are all incorporated within one device that can be installed in standard light fixtures, eliminating the need for separate smoke detectors and lighting systems.
Solution Approach 2:
The LED light bulb serves multiple functions simultaneously: it provides illumination through the light emitting means, detects smoke through the smoke detector means, detects carbon monoxide through the carbon monoxide detector means, and provides alarm signaling through both audible and visual alarm means. This multi-functional design resolves the contradiction by making one device perform the work of multiple separate devices.
2Ease of operation
If battery-powered detectors are used, then portability and ease of installation are improved, but reliability deteriorates due to battery replacement requirements
Solution Approach 1:
The system incorporates a rechargeable battery that is automatically recharged when AC power is available. The control means monitors the battery charge level and manages power distribution, allowing the system to maintain continuous operation without user intervention for battery replacement. The visual alarm means also provides status information about battery and AC power states.
3Reliability
If visual alarm signals are added to audible alarms, then alarm effectiveness is improved, but energy consumption increases
Solution Approach 1:
The visual alarm means uses colored LED indicators to convey different alarm conditions and system states. Different colors indicate different types of hazards (smoke vs. carbon monoxide), battery status, and AC power status. This provides rich information communication with minimal energy consumption compared to traditional visual alarm systems.
Solution Approach 2:
The visual alarm LEDs operate in periodic or intermittent patterns rather than continuously, providing alarm signaling only when needed. The system alternates between standby mode with minimal energy consumption and active alarm mode with full visual and audible signaling, resolving the energy effectiveness contradiction.
4Loss of information
If networked communication is implemented, then system coordination and information sharing are improved, but device complexity increases
Solution Approach 1:
The base station serves as a central intermediary that receives signals from multiple LED light bulb detectors, processes the information, and provides coordinated responses. The base station manages the network communication, stores detector information, and controls the visual and audible alarm outputs, simplifying the complexity by centralizing the communication management rather than requiring direct peer-to-peer communication between all devices.

AI summary
A networked visual and audible alarm apparatus with base station provides audible and visual alerts upon detection of smoke, carbon monoxide, and gas. The apparatus adapts to a light bulb socket to provide normal lighting when no event is detected. Multiple apparatuses are systematically disposed through different sections of a structure. Each apparatus independently emits an audible signal, dependent on the type of event detected in the respective section for the apparatus. Each alarm apparatus provides a colored high strobe light that illuminates at a color and intensity that varies, dependent on type of event detected. A microphone initiates the audible signal and the high strobe light upon detecting an audible signal from an adjacent alarm apparatus. Voice commands power off the alarming apparatus. A base station controls and monitors a network of apparatuses, and is programmable based on a code that is assigned to each alarm apparatus.
