Security Floodlight LED Scan to Simulate Camera Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security floodlights lack an integrated decoy feature to simulate the operation of a low-light security camera, making it difficult to deter intruders effectively without the actual presence of a camera.
Innovation Solution
A security floodlight with a series of LEDs arranged in a horizontal line that activate in a rotating manner when off, simulating the operation of a low-light security camera, controlled by a simple circuit to ensure decoy and illumination functions do not interfere.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If actual security cameras are installed to provide monitoring capability, then security monitoring function is improved, but installation cost and system complexity increase
Solution Approach 1:
The patent uses LED indicators arranged in a horizontal line that scan across the housing to visually replicate the appearance and behavior of a security camera's recording indicator, creating a decoy that mimics camera operation without requiring actual camera hardware
Solution Approach 2:
The patent replaces expensive, complex security camera systems with an inexpensive LED-based decoy system that uses simple components (LEDs, resistors, control circuit) to achieve the visual effect of camera monitoring, significantly reducing installation cost and complexity
2Reliability
If decoy LED indicators are added to simulate camera operation, then deterrence effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent divides the housing into multiple segments along the horizontal axis and places individual LED indicators in each segment, allowing them to illuminate sequentially to create the scanning effect that mimics camera operation
Solution Approach 2:
The patent implements periodic illumination of the LED indicators in a scanning sequence across the horizontal line, creating a rhythmic visual pattern that simulates the periodic operation of a security camera's recording indicator
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 rotating LED sequence creates a visual effect mimicking a functioning security camera, enhancing deterrence without the need for a real camera, providing an affordable and effective decoy solution.
Implementation Method 1
a series of light-emitting diodes (LEDs), preferably red, arranged in a horizontal line. These LEDs activate in a rotating manner
Data Source
AI summary
A security floodlight has a light panel mounted in a housing for illuminating an area in proximity to the housing, an array of light emitting diodes (LEDs) mounted in the housing and arranged in a horizontal single row, and a controller configured activate the light panel based on an input signal and to sequentially activate each of the LEDs in the array of LEDs in a rotating sequence only when the light panel is not activated. The input signal may be received from a proximity sensor mounted in the housing that indicates the detection of movement in an area in close proximity to the security floodlight. The rotating sequence simulates operation of a low-light security camera by sequentially illuminating each LED in the array of LEDS in a rotating manner from a first end of the horizontal single row to a second end of the horizontal single row.
