Description

The present invention relates to an emergency lighting at night in a general home, and particularly provides an emergency illuminator that is turned on simultaneously with the occurrence of a fire and an earthquake to enable quick evacuation behavior. It is.

In ordinary households, fire alarms for houses are installed in bedrooms and the like. Residential fire alarms have a function of notifying a fire by sounding and turning on a red lamp when a fire is detected.
Fire Service Law Enforcement Order Article 5-6

However, the red lamp provided in the conventional residential fire alarm does not have sufficient illuminance to illuminate the room. On the other hand, in ordinary households, there are many cases where the night light is not turned on at the time of going to bed at midnight. In this case, when a fire or earthquake occurs at bedtime in the middle of the night, you will be in a darkness and you will not be able to turn on the light switch of the interior light well, or the power will be turned off and the room will be brightened It is assumed that evacuation action cannot be taken smoothly.

Therefore, the present invention is provided with a light detector that detects lighting of a red lamp of a residential fire alarm device and a vibration detector that detects vibration due to an earthquake, and the illumination lamp is turned on by a detection signal of the light detector or the vibration detector. We propose an emergency illuminator that lights for a certain period of time.

By providing the emergency lighting device of the present invention in the vicinity of a fire alarm for a residential house in a bedroom, when a fire or an earthquake occurs during sleep in a home that does not turn on a night light at bedtime, the room is automatically By becoming brighter, you can keep calm and take calm actions such as performing initial fire fighting activities and searching for flashlights for evacuation, as well as things that fall during an earthquake It can be avoided. In addition, in homes that sleep with nightlights worried about fires and earthquakes during sleep, the nightlights can be turned off by providing the emergency lighting device of the present invention in the vicinity of a residential fire alarm in the bedroom. This will not only save electricity consumption at midnight, but it can also be expected to eliminate the light and inability to sleep well.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an emergency illuminator according to the first embodiment of the present invention. Reference numeral 1 denotes a light receiving detection unit that receives light from an alarm lamp 11a (FIGS. 2 and 5) provided in a residential fire alarm, and 2 denotes a lighting circuit unit of the illumination lamp 3. The illumination lamp 3 is turned on by an ON signal that is detected and output, and a timer function is provided to turn off the illumination lamp 3 after a certain period of time has elapsed from the start of lighting of the illumination lamp 3. 3 is an illumination lamp mainly composed of a lamp made of white light LED and a reflecting plate, and 4 is a power supply unit which is a supply source of operating power of each unit, which is mainly a battery and a remaining battery level detection / warning circuit.

FIG. 2 shows an example of the internal structure of the light receiving detector 1. Reference numeral 11a denotes an alarm lamp provided in a residential fire alarm. The light receiving detector 1 includes a sensor 1a for receiving the lighting light of the alarm lamp 11a and ambient light, Two sensors 1b that receive room light are provided, and the outputs of the two sensors 1a and 1b are compared and discriminated by a comparator 1c. When the alarm lamp 11a provided in the fire alarm for houses is turned on in a dark room, the light of the alarm lamp 11a enters the sensor 1a, and almost no light enters one sensor 1b. The lighting of the alarm lamp 11a can be detected by a significant difference in the amount of light received by the sensor 1b. Here, when the surroundings are bright in the daytime or the like, even if the light of the alarm lamp 11a enters the sensor 1a, there is no significant difference in the amount of light received from the sensor 1b, and therefore the lighting of the alarm lamp 11a can be detected. Although there are cases where the surroundings are sufficiently bright and the lighting lamp 3 does not need to be turned on, it is not necessary to turn on the lighting lamp 3, and the function can be sufficiently achieved with a simple configuration as in the embodiment.

With the above-described configuration, it is possible to turn on the emergency illumination lamp in conjunction with the lighting of the alarm lamp of the residential fire alarm when a fire occurs in the darkness at midnight.

FIG. 3 is a block diagram showing the configuration of the emergency illuminator according to the second embodiment of the present invention. A vibration detection unit 5 for detecting vibration caused by an earthquake is provided in parallel with the light reception detection unit 1, and the detection signal of the light reception detection unit 1 and the detection signal of the vibration detection unit 5 are respectively parallel to the OR circuit unit 6. Entered. When either the detection signal of the light reception detection unit 1 or the detection signal of the vibration detection unit 5 is input to the OR circuit unit 6, the lighting circuit unit 2 starts to turn on the illumination lamp 3, and from the start of lighting of the illumination lamp 3. The illumination lamp 3 is turned off after a certain period of time, 3 is an illumination lamp mainly composed of a white light LED lamp and a reflector, and 4 is a power supply unit that is a source of operating power for each unit, mainly a battery. And a battery level detection / warning circuit. With the configuration as described above, it is possible to provide a device that automatically turns on the illumination lamp 3 not only when a fire alarm for a house detects a fire but also when an earthquake occurs. . Here, the ambient brightness is simultaneously monitored from the amount of incident light of the sensor 1b (FIG. 2) of the light receiving detector 1, and the illumination lamp 3 is not turned on when it is determined that the surrounding is sufficiently bright. As a result, it is possible to prevent the illumination lamp 3 from turning on in the event of an earthquake when it is bright, so that unnecessary battery consumption can be prevented.

FIG. 4 shows an example of the internal configuration of the vibration detector 5 of the second embodiment, which has a simple structure in which vibration is detected when the weight 5b attached to the spring 5a strikes the electrical contact 5c by vibration. The strength of the spring 5a and the mass of the weight 5b are appropriately set so that, for example, the vibration of an earthquake having a seismic intensity of 3 or more can be detected. In this case, when an earthquake having a seismic intensity of 3 or more occurs, the detection signal of the vibration detection unit 5 in FIG. 3 is input to the lighting circuit unit 2 through the OR circuit unit 6 and the lamp of the illumination lamp 3 is lit. Even after the earthquake has stopped, the illumination lamp 3 continues to be lit until a predetermined time set in advance in the lighting circuit unit 2 elapses, and the certification lamp 3 is turned off with the lapse of a certain time, that is, automatically recovered. Wait until the next earthquake occurs.
