Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, when a flashlight hung vertically on a pillar in a room with the switch (10) turned on feels vibrations due to an earthquake, etc., the flashlight will automatically turn on and during the vibration. Of course, even after the vibrations have stopped, the light remains on for a certain period of time and then turns off automatically. However, in the above phenomenon, the light turns on only when the surroundings are dark, and when the surroundings are bright, the light does not turn on even if a vibration is felt.However, if the light receiver (4) is removed from this circuit, the light will turn on only when the surroundings are dark. This invention relates to an energy-saving flashlight that is configured to light up regardless of the situation.

A flashlight constructed in this manner allows a person to easily locate the person's location even in the dark, making it convenient for a person to take action. In addition, when you pick up this flashlight and carry it with you, the vibration will keep the light on while you are carrying it, and if you walk into a brightly lit area, you will not have to operate the switch.
It automatically turns off the light immediately, eliminating unnecessary battery consumption and helping to save energy. Note that even if the switch (10) is left on, the battery will not be consumed in the standby state.

Also, if you want to turn on the light in a bright place, use the receiver (
If you hide 4) with your thumb or other object and avoid exposing it to light, you can achieve your goal.

Previously, for emergency use, there were ordinary flashlights or rechargeable flashlights that would turn on when you picked them up by flipping a switch. With this method, if there is a power outage due to an earthquake at night, it is inconvenient to find a flashlight in the dark.

This invention eliminates this inconvenience and ensures human safety.

From the above, the present invention is effective for emergency use when installed in guest rooms, hallways, etc. of ordinary homes, inns, hotels, etc.

Next, to explain its structure, a circuit board (3) made up of electronic components is sandwiched between the positive electrode of the battery (1) and the light bulb (2), and the contact terminal (14) is connected to the terminal of the flashlight body. to electrically configure this circuit. This method is convenient for replacing batteries.

The light receiver (4) is attached to the surface of the tip of the flashlight barrel. This is a good position for light to enter the light receiver (4), and depending on the usage, it is also a good position for blocking the incident light with your thumb or the like.

The electronic circuit is configured as shown in Figure 2, and the experimental results show that the duration of the vibration stopper and lighting is as follows:
Approximately 15 to 20 seconds is appropriate. The length of time that the light remains on can be changed by adjusting the capacitance of the capacitor (8).

The vibration element that senses vibration and operates the electronic circuit is
It has a pendulum shape (5) or a dish shape (6) and is assembled into a circuit board (3). The sensitivity of this vibrating element is pendulum-shaped (
Regarding the item 5), the elasticity of the hanging wire (11), the pendulum (
12), the dish shape (6) can be changed depending on the diameter and depth of the dish, or the weight and diameter of the metal ball (13), but in practice, seismic intensity 3
It is preferable to operate at a certain level. In addition, if the sensitivity of the vibration element is further improved so that it operates at a seismic intensity of about 1, there is also a mode of use for determining whether an earthquake has occurred.
