Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disaster prevention device that automatically lights up in the event of an earthquake and dark surroundings.

[0002]

[Prior art]

 Conventionally, a lighting device that has a combination of detecting such an earthquake and detecting the surrounding illuminance to automatically turn on the light when the illuminance is below a certain level has not yet been developed.

[0003]

[Problems to be solved by the device]

 The present invention is very dangerous because it becomes dark when there is a power outage due to an earthquake such as night, and it is a device that senses the earthquake and the surrounding brightness, and automatically illuminates by configuring the circuit under the following conditions. Is intended to be developed.・ To obtain highly efficient lighting with low power consumption. -Can be manufactured at low cost using ordinary commercial batteries and lighting. -It is compact and can be installed in any place. It can also be used as a flashlight by removing it.

[0004]

[Means for solving the problem]

 In order to obtain highly efficient lighting, the present invention uses a fluorescent lamp for lighting and an inverter circuit for driving the fluorescent lamp, and uses a commercially available battery as a power source. An earthquake in which a spherical weight is connected as a seismic sensing unit with a piano wire or string and a circular contact plate is attached around it to shake the spherical weight due to vibration, and the vibration is sensed by touching the surrounding contact plate. The latch unit that supplies power to the inverter unit and the illumination unit is operated by the CdS cell whose electric resistance changes depending on the degree of brightness of the sensing unit and the surroundings, or both sensing signals obtained by the illuminance sensing unit by another optical sensor. This means that continuous lighting is used.

[0005]

[Action]

 When the earthquake detector of (1), the illuminance detector of the surroundings of (2), the latch part of (3), and the power source of (4) are electrically connected as one loop, when an earthquake occurs and the surroundings are dark Then, make the latch part of (3) operate. In the operation of the latch part (3), the relay contact is closed and power is supplied from the power supply part of (6) to the inverter part of (4). The inverter part (4) converts it into electric power required for discharge, and the lighting part (5) lights it.

[0006]

【Example】

 As a seismic detector, a spherical weight was attached to the tip of the piano wire, and by vibrating it, it was brought into contact with the surrounding contact plate and made an electrical contact. A CdS cell whose electric resistance changes depending on the ambient brightness is used as the illuminance sensing unit, and the circuit is a closed circuit when the illuminance is below a certain level. A small relay is used for the latch part, and the contacts are normally open, so there is no battery drain. By electrically connecting the power supply unit, both sensing units, and the latch unit in series, it becomes conductive due to a momentary vibration under a certain illuminance, and the relay of the latch unit is held and the relay unit contacts through the relay to the inverter unit from the power supply. Power was supplied to turn on the 4 W fluorescent lamp. It was proved that four AAA batteries were used as a power source to maintain sufficient brightness for 20 minutes or more continuously.

If the electrical contacts of the earthquake detector are used in a short-circuited state, it can be used as a night-time automatic lighting device that automatically lights up when the surroundings become dark. In this case, unless a rechargeable battery is used or a power source is supplied from a commercial power source, the amount of battery consumption is large and it is not practical.

[0008]

[Effect of device]

 The present invention eliminates fear and anxiety by lighting when an earthquake and darkness overlap, and enables deposition and calm behavior.
