Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stationary light with a radio which is always inserted into a power outlet of a commercial power source and operates according to power failure and illuminance.

[0002]

2. Description of the Related Art In the event of a disaster such as an earthquake, especially at night, when there is a power outage, it will be dark and the information will be cut off, making it difficult to grasp the surrounding situation, depending on the extent and scale of the disaster. It also hinders accurate judgment and quick evacuation behavior. Permanent lights (emergency lights, security lights) are provided as appropriate for disaster countermeasures such as earthquakes, etc., and even if there is a power outage, the interior of the room will be bright, so it has been necessary to prevent secondary disasters. Is also helpful.

As a conventional permanent light (emergency light, security light), for example, a plug is always inserted into an outlet,
Each manufacturer sells a plug-in that lights up automatically when there is a power outage and can be removed and carried as a light. In such a permanent light, in order to be light and easy to carry, and to realize long-time lighting, a nickel-cadmium battery or lead battery is built in,
Various measures have been taken, such as switching from two fluorescent lamps to one lamp so that they can be lit for a long time.

[0004]

However, as described above, the conventional stationary light that is always plugged into an outlet with a plug is used in a dark room at night or in a room without lighting. Useful when equipped, but not very useful during the bright daytime. In addition, the above-mentioned conventional fixed lights do not operate unless there is a power outage or if they are not removed, so if left in the normal state for a long period of time, it will not be known that the lamp has deteriorated or the circuit has failed. There is also a problem. Therefore, it is necessary to check the operation by removing the standing light from time to time in order to confirm that it operates reliably in an emergency, and special consideration must be given to the maintenance.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a stationary light with a radio capable of providing useful information together with the lighting of an illumination lamp in accordance with a power failure or ambient brightness. It is what

[0006]

To this end, the present invention is a stationary light with a radio that always operates by responding to a power failure and illuminance by always inserting a plug into an outlet of a commercial power source. The secondary battery is charged by the commercial power source. Then, when a power failure and low illuminance are detected, the radio is turned on and the inverter is activated to turn on the electroluminescence lamp.

When a power failure is detected, the radio is turned on, when a low illuminance is detected, the commercial power source turns on the electroluminescence lamp at a low brightness, and when a power failure is detected, the secondary battery starts the inverter to start the electroluminescence lamp. Is turned on with high brightness.

[0008]

In the radio fixed light of the present invention, the secondary battery is charged by the commercial power source, and when the power failure and the low illuminance are detected, the radio is turned on and the inverter is started to turn on the electroluminescence lamp. In addition to brightening the surrounding area during a power failure, it is possible to provide information on disasters, etc. by radio broadcasting. Usually, when the surroundings have low illuminance (for example, 5 lux) or less, the night light is turned on by the optical sensor and lights up at, for example, 9 lux, and thus has a function as a footlight.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a radio-equipped permanent light according to the present invention. 1 is a commercial power supply, 2 is a secondary battery, 3 is an AC switch, 4 is a charging circuit, 5 is a power failure detection circuit, and 6 Is an illuminance detection circuit, 7 is a logic circuit, 8 is an inverter, 9 is an electroluminescence lamp (EL), 1
0 indicates a radio receiver.

In FIG. 1, a commercial power source 1 is connected by inserting a plug into an outlet, and a secondary battery 2 is charged from the commercial power source 1 through a charging circuit 4, an inverter 8 and a radio receiver 10. It is used as a power source of. When the AC switch 3 is turned on, the commercial power supply 1 is connected to the electroluminescence lamp (EL) 9 to perform low-luminance lighting, and when turned off, it becomes a half-wave rectifier circuit to stop the low-luminance lighting of the electroluminescence lamp 9. At the same time, the secondary battery 2 is charged through the charging circuit 4. The power failure detection circuit 5 detects the power failure of the commercial power supply 1, and the power failure detection signal is the radio receiver 1
It is used as a signal for turning on 0 and starting the inverter 8. The illuminance detection circuit 6 detects brightness using an optical sensor, and a low illuminance detection signal when it becomes darker than a predetermined brightness is used as a signal for turning on the AC switch 3 and activating the inverter 8. Used. When the power failure detection circuit 5 outputs a power failure detection signal and the illuminance detection circuit 6 outputs a low illuminance detection signal, the logic circuit 7 generates a start signal for the inverter 8 by the logic process. When the output of the logic circuit 7 is activated, the inverter 8 uses the secondary battery 2 as a power source, for example, 130V, 80V.
The output is converted to 0 Hz, and the electroluminescence lamp 9 is turned on with high brightness. When the electroluminescence lamp 9 is driven by the commercial power supply 1 of 100 V and 50 Hz, for example, it emits light with a low brightness of about 9 candela, whereas when it is driven by the output of the inverter 8 of 130 V and 800 Hz, it is 140 It uses a candela and a glass-sealed EL that emits approximately 15 times higher brightness. The radio receiver 10 has previously tuned to a predetermined reception frequency, and when the power failure detection circuit 5 outputs a power failure detection signal, the secondary battery 2 is used as a power source to receive the radio wave of the selected broadcasting station and broadcast it. Yes, for example AM radio.

Next, the operation will be described. As will be described later, the radio-equipped permanent light of the present invention has the electroluminescence lamp 9 and the speaker of the radio receiver 10 arranged on the front of the case, the circuits shown in FIG. 1 are housed inside, and a plug (not shown) on the back. ) And attach this plug to a commercial power source 1
It can be used as a standing light by plugging it into an outlet (not shown). When the commercial power supply 1 is supplied and the ambient illuminance is equal to or higher than a predetermined level, the AC switch 3 is turned off and the inverter 8 is also turned off by the output signals of the power failure detection circuit 5 and the illuminance detection circuit 6. ing. Therefore, in this state, the secondary battery 2 is only charged through the charging circuit 4.

Next, when the surroundings become dark and the illuminance detection circuit 6 outputs a low illuminance detection signal, the logic circuit 7 outputs the start signal of the inverter 8 unless the power failure detection circuit 5 outputs the power failure detection signal. No output is made and the AC switch 3 is turned on. Therefore, the electroluminescence lamp 9 is lit by the commercial power source 1 at low brightness.

When the commercial power supply 1 fails and the power failure detection circuit 5 outputs a power failure detection signal, unless the illuminance detection circuit 6 outputs a low illuminance detection signal, the start signal of the inverter 8 is not output, Only the radio receiver 10 is turned on. Therefore, the broadcasting of the selected broadcasting station flows.

Further, when the commercial power source 1 loses power and the power failure detection circuit 5 outputs a power failure detection signal, and the surroundings become dark and the illuminance detection circuit 6 outputs a low illuminance detection signal, the logic circuit 7
Outputs an activation signal of the inverter 8, so that the electroluminescence lamp 9 is turned on with high brightness by the output of the inverter 8. At this time, the radio receiver 10 is also turned on and the broadcast of the selected broadcasting station flows.

And C2 are the secondary battery 2 when the electroluminescence lamp 9 is turned on with high brightness by the output of the inverter 8,
It constitutes a bypass circuit for the diodes D1 and D2. The optical sensor 14 has a low impedance when the illuminance is high and a high impedance when the illuminance is low. The transistor TR1 and the diode D3 form an AC switch 3, and the logic gate 17 has a low illuminance, for example, about 5 lux, and the optical sensor 14 has a high impedance.
The output goes high. Therefore, when the illuminance becomes low, the transistor TR1 of the AC switch is turned on. These optical sensor 14, resistor R5, and logic gate 17
The illuminance detection circuit 6 is configured by. On the other hand, the logic gate 16 constitutes the power failure detection circuit 5, and when the commercial power source fails, the input at the series connection point of the diodes D1 and D2 becomes low level, and therefore the output becomes high level.
