Hereinafter, an emergency light combined television receiver (hereinafter abbreviated as a television receiver) according to an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a diagram showing a configuration of a television receiver according to an embodiment of the present invention.
FIG. 2 is a diagram showing a configuration of a television receiver according to another embodiment of the present invention.

As shown in FIG. 1, a television receiver 1 according to an embodiment of the present invention includes a lightness detection unit 2, a power failure detection unit (detection unit) 3, a power storage unit 4, a control unit 5, and a switching unit 6. The power supply unit 7, the blocking unit 8, the receiving unit 9, and the light emitting unit 10 are supplied with power from an external power supply unit 11.
As shown in FIG. 2, a television receiver 20 according to another embodiment of the present invention is obtained by adding an intermittent portion 21 to the television receiver 1 of FIG.

The brightness detection unit 2 detects the brightness around the television receiver, and generates a brightness signal that turns on brightness that does not interfere with vision and turns off brightness below a predetermined value that affects vision.
The power failure detection unit 3 detects a power supply state of 1 from the power supply unit 11 and is turned on when a power failure occurs when 1 power is supplied, and is turned off when a power failure occurs without power supply. Is generated.

The power storage unit 4 is made of a rechargeable battery such as a lithium ion secondary battery, and stores a part of the 1 power supplied from the power supply unit 11 as the 2 power.
The control unit 5 extracts a power failure signal that is OFF when the brightness signal is OFF and the power failure detection signal is OFF, and is otherwise ON.
The switching unit 6 selects 1 power from the power supply unit 11 when the power failure signal is ON by the control unit 5 and selects 2 power from the power storage unit 4 when the power failure signal is OFF. Further, a selection signal is generated that is ON when the power failure signal is ON and OFF when the power failure signal is OFF.
The power supply unit 7 distributes the power selected by the switching unit 6 to the receiving unit 9 and the light emitting unit 10 via the blocking unit 8.

The blocking unit 8 supplies power to the receiving unit 9 when the selection signal from the switching unit 6 is ON, and blocks power supplied to the receiving unit 9 when OFF.
The receiving unit 9 receives a television broadcast and converts it into a television image signal.
The light emitting unit 10 receives the television image signal converted by the receiving unit 105 and causes the display unit that displays the image to emit light, and displays a television image by light emission of a display such as liquid crystal (light emission is backlight) or plasma. To do.

The power supply unit 11 is mainly a power plant of a power company, and power is supplied from the power company to a household outlet via an electric wire.
The intermittent unit 21 supplies power to the light emitting unit 10 intermittently by repeatedly cutting off and supplying the power supplied from the power supply unit 7 at regular intervals during a power failure.

Next, the operation will be described.
(Non power failure)
When power is supplied from the power supply unit 11 to the television receiver 1, in the television receiver 1, the power failure detection unit 3 detects the power from the power supply unit 11 and outputs an ON power failure detection signal. Therefore, the control unit 5 turns on the power failure signal based on the ON power failure detection signal, and the power storage unit 4 stores a part of the power supplied from the power supply unit 11.
The switching unit 6 selects the power from the power supply unit 11 because the power failure signal generated by the control unit 5 is ON, and the power unit 7 receives the power selected by the switching unit 6 via the cutoff unit 8. 9 and the light emitting unit 10.
The receiving unit 9 operates with power supplied from the power supply unit 7 to receive a television broadcast and convert it into a television image signal.
And the light emission part 10 is supplied with electric power from the power supply part 7 similarly to the reception part 9 and operates. The television image signal converted by the reception part 9 is input, and the display part that displays the image emits light. A television image is displayed by light emission of a display such as a liquid crystal (light emission is a backlight) or plasma.

(When it is bright during a power failure)
Next, when power is not supplied from the power supply unit 11 to the television receiver 1 due to a disaster or the like, the power failure detection unit 3 generates an OFF power failure detection signal.
When the brightness detection unit 2 detects brightness that does not interfere with vision, the control unit generates an ON power failure signal, and the power supply unit 11 remains in the power supply state in the switching unit 6 due to the power failure signal. Since no electric power is supplied from the switching unit 6, the operation of the television receiver 1 is stopped.

(During power failure and dark)
Next, when the brightness detection unit 2 detects a brightness of a predetermined value or less that can be visually perceived, the control unit generates an OFF power failure signal. Therefore, the switching unit 6 uses the power from the power storage unit 4 by the power failure signal. The cutoff unit 8 cuts off the electric power supplied from the power source unit 7 to the reception unit 9 via the cutoff unit 8.
In the power supply unit 7, the power from the power storage unit 4 is input from the switching unit 6 and the power input to the light emitting unit 10 is supplied.
The light emitting unit 10 emits light by the electric power supplied from the power supply unit 7 and illuminates the periphery of the television receiver 1.

  As shown in FIG. 2, in a television receiver 20 according to another embodiment of the present invention, an intermittent unit 21 is added to the television receiver 1 of FIG. The electric power consumed by the light emitting unit 10 is further reduced by repeatedly cutting off and supplying the electric power to the light emitting unit 10 at regular intervals and supplying the light to the light emitting unit 10 intermittently.

  The television receiver 1 and the television receiver 20 are installed in a well-viewed place such as a living room or a family private room, thereby illuminating the entire room where the television receiver is installed in an emergency for a long time. Therefore, you can spend enough time searching for portable radios, flashlights, or emergency foods that are necessary for emergencies.

In this way, if you add the function to detect when the surroundings are dark like nighttime and the function to reduce the power consumption of the television receiver, it will not turn on when the lighting is unnecessary even in the event of a power failure, It is lit only in the dark when illumination is required, and can be lit for a long time.
In particular, since the role as illumination is emphasized, the reception operation of television broadcasting or the like that consumes power is stopped.

  As described above, it is possible to provide an emergency light combined television receiver that serves as lighting in an emergency situation and does not operate except in an emergency situation.

It is a figure which shows the structure of the television receiver which concerns on embodiment of this invention. It is a figure which shows the structure of the television receiver which concerns on other embodiment of this invention.
