TH18844U - Emergency lights with motion sensors. - Google Patents

Abstract

Page 1 of 1. Summary of the Invention: The emergency light with motion sensor described in this invention is equipped with a motion sensor to allow the emergency light to illuminate for a certain period of time at night or in dark areas where the power supply is uninterrupted. A light intensity sensor detects light intensity; if a certain level of visible light is reached, even if motion is detected, the emergency light will not illuminate. This minimizes battery power consumption, thus conserving battery power for as long as possible during power outages.

Claims (4)

------24/01/2020------(OCR) Page 1 of 1 page Claims 1. Emergency light with motion detection, consisting of an emergency light (1) with a light bulb (2) that will turn on when the normal power supply is interrupted, with a control unit (3) that processes and commands the light bulb (2) to turn on, which has the following characteristics: a motion detection unit (4) that detects movement and sends a signal to the control unit (3), and a light detection unit (5) to detect whether the light intensity is as specified and sends a signal to the control unit (3) to process and command the light bulb (2) to turn on. 2. Emergency light with motion detection, as per item 1, where the control unit (3) processes and commands the light bulb (2) to turn on when it receives a light intensity value from the light detection unit (5) as specified above, i.e., a light intensity value less than 5 lux. 3. Emergency light with motion detection, as per item 1 or item 2, where the light bulb (2) will be illuminated for a period of 3 minutes in the event that the motion detector (4) detects movement and the light detector (5) detects a light intensity less than the specified value. 4. Emergency lights with motion detectors according to clauses 1 to 3, where the motion detector (4) is powered by a normal power supply that has been converted from AC to DC and does not use battery power. ------------ Page 1 of 1 page Claims 1. Emergency light with motion sensor, which consists of an emergency light (1) with a light bulb (2) that will turn on when the normal power supply is interrupted, and a control unit (3) that processes the information and commands the light bulb (2) to turn on. It has a specific characteristic: a motion sensor (4) that detects movement and sends a signal to the control unit (3), and a light sensor (5) that detects whether the light intensity is as specified and sends a signal to the control unit (3) to process the information and command the light bulb (2) to turn on. 2. An emergency light with a motion sensor as per item 1, in which the control unit (3) processes and commands the light bulb (2) to turn on when the specified light intensity is less than 5 lux. 3. Emergency lights with motion detection as per clause 1 or clause 2, in which the light bulb (2) will be illuminated for a period of 3 minutes in the event that motion is detected and the light intensity is less than the specified value. 4. Emergency lights with motion sensors according to any of the items 1 to 3, where the motion sensor (4) is powered by a normal power supply that has been converted from AC to DC and does not use battery power.
