Description

[Detailed description of the invention] [Field of industrial application] The present invention is a remote control device that turns on a desk lamp for a set time using a human voice, and stops the lamp when it is turned on using the same voice. It is used as a. Furthermore, a device has been added that allows free manual control of the illuminance.

[Conventional technology]

Conventional techniques include, for example, Japanese Utility Model Application No. 58-50637 and US Pat. No. 4,433,362 by the same inventor.

[Problems that this invention attempts to solve]

First, when controlling the lighting of a lighting fixture such as a desk lamp powered by an AC power source using the above-described technology, it is convenient to extend the lighting time to about 1 minute and to turn off the light midway through the lighting time. However, there are problems that remain unresolved.

Second, when the light is turned on by the sound of a hissing sound, which is a resonant friction sound of air passing between the roof of the mouth and the tongue,
If you suddenly turn on a 100 watt light bulb, you will be dazzled, so it is necessary to adjust the brightness to suit each individual, but this has become a problem.

Thirdly, it is desirable to be able to freely adjust the brightness manually when the lamp is turned on. There are products of this type on the market today, but they have some problems that remote control lighting equipment doesn't have.

[Means for solving problems]

Using an electrical circuit that includes a flip-flop circuit, the output of the flip-flop circuit is held at a low level when the power is turned on (when the desk lamp is plugged into an outlet), and the output of the flip-flop circuit is held at a low level, producing a C-tone (the meaning of the sound "sh" mentioned above). ) The flip-flop circuit is inverted and set to high level by the detection signal of The flip-flop circuit is reversed to de-energize the light bulb.

Further, when the C- tone is inputted again during the above-mentioned lighting, the output of the flip-flop circuit is changed to a low level by the detection signal, and a means is added for turning the switching element into non-conducting state and turning off the light. This solves the first problem.

Rectifying alternating current using a diode bridge circuit,
By comparing the rectified output and the DC output of a variable resistor that can be adjusted manually, the light is dimmed by adjusting the input of the light, and when the light is turned off using the manual electric switch at the desired brightness, the brightness when the light is turned off is as follows. As a configuration that allows lighting control by C-sound,
This solves the second problem.

When the light is turned on by the manual switch, the brightness of the light can be freely adjusted by the above-mentioned means, which solves the third problem.

[Effect]

By the means described in the previous section, the light is turned on by the sound C and is automatically turned off after about one minute. When the errand is finished within that time, the C- sound is generated again and the light is turned off.

When the electric switch is turned on, the switching element is short-circuited, so the lamp lights up in the same way as a normal desk lamp. You can turn off the light by turning off the electric switch. Turning off the desk lamp when you go to bed has an effective effect because when you wake up in the middle of the night to do something, you can turn it on with a C-tone. It is especially effective for elderly people. In addition, since the brightness at the time of lighting can be adjusted in advance, dazzling can be prevented.

When the light is turned on by the manual electric switch, by changing the variable resistor using the comparison circuit described above, the average time of energization can be changed, and the light can be dimmed using the transistor.

[Embodiments] The apparatus of the present invention will be described with reference to the embodiments shown in FIG. 1 and subsequent figures. Since members with the same symbols in each drawing are the same, their repeated explanations will be omitted.

FIG. 1 is an external view of a desk lamp which is an embodiment of the device of the present invention.

In FIG. 1, a support stand 1 has a support stand 3 erected thereon, and a light bulb and its socket are installed at the upper end of the support stand 1 by well-known means, but these are not shown.

Symbol 2 is shaded and has various designs.

Lighting control is performed by manually operating the knob of the electric switch 20. Symbol 1a is a bulge on the upper surface of the support base 1, which is a part of the spherical surface, and a microphone is attached to an opening 4 at the apex of the spherical surface so that sound waves can be received.

This invention does not use a special sound source,
The purpose of the present invention is to obtain a device that remotely controls the lighting of a desk lamp by using a special human vocalization means.

There are many prior art remote control means of this type, as seen in television remote controls. However, all of these utilize specially constructed sources of oscillation, such as acoustic waves, light waves, or radio waves. However, these oscillation sources have the disadvantage that they include consumable parts such as batteries and are large and expensive. Furthermore, if you are careless and forget to carry it with you, a convenient remote control device turns into an inconvenient device. Also, turning on a desk lamp in the dark in search of an oscillation source is considered an inconvenient and contradictory idea.

There is also a means to control the lighting using human words, but a device that understands and makes decisions based on words has the drawback of being expensive and impractical.

Some devices are activated by the sound of clapping hands, but they are not practical because sounds from the environment, such as the sound of objects hitting each other, can act as a false signal. There are also cases where it is desired to control lighting without generating sound. For example, there is a case where there is a sleeping infant. Even in such cases, effective means are required, but there are none that are practical. It is possible to use a commercially available touch switch, but this is expensive and has the added disadvantage of not being able to detect it in the dark, making it impractical.

The device of the present invention is characterized by eliminating the above-mentioned drawbacks and contradictions, and details thereof will be explained with reference to FIG. 1 and the subsequent drawings.

FIG. 2 is an explanatory diagram of a control circuit that controls lighting.

In FIG. 2, the microphone 6 receives a C-sound coming from the direction of arrow B, and its output is amplified by an amplifier 7, and a signal of 5KC or more is amplified by a high-pass filter consisting of a capacitor 8a and a resistor 8b. ,
Rectification and smoothing are performed by a diode 9a and a capacitor 9b. By transforming the microphone diaphragm,
When configured to resonate only with sound waves of 5KC or higher, the high-pass filter circuit (capacitor 8a, resistor 8b) becomes unnecessary.

Symbol 16 is a commercial AC power supply, which is rectified by a diode bridge circuit 12, and its output is shown by curves 29a and 29 in the time chart of FIG.
b,...

The voltage divided by the resistors 13a and 13b is
The voltage is smoothed into direct current by a capacitor 13c, and becomes the voltage applied to transistors 10a and 10b. It also serves as a power source for the microphone 6, amplification circuit 7, and the like.

The above-mentioned C-tone detection signal is transmitted through transistor 1.
It becomes the base input of 0a and conducts it, so
Transistor 10b turns non-conductive.

Since the resistor 19 has a relatively high resistance, the capacitor 11 is charged with a substantially constant current.

The time constant of capacitor 11 is made relatively large. That is, when the C-tone continues for about 0.5 seconds, the Zener diode 21a breaks down and temporarily holds one input of the AND circuits 22a, 22b at a high level.

When the power is turned on, the flip-flop circuit 2
3 (hereinafter referred to as F circuit) is reset,
Since the output of the Q terminal is at a high level, the upper input of the AND circuit 22a is also at a high level.

In order to make the output of the terminal of the F circuit 23 high level when the power is turned on, it is preferable to adopt the following means.

The R terminal of the F circuit 23 is energized from the output side of the Zener diode 21b in FIG. 2 via an inverting circuit and a differentiating circuit for its output.

When the power is turned on, the Zener diode 21b
Since the output of is low level, the output of the inverting circuit is high level. Therefore, by the output of the differentiator circuit,
Since the R terminal of the F circuit 23 is energized and the output of the terminal becomes high level, the purpose is achieved.

Therefore, the output of the AND circuit 22a temporarily becomes high level due to the electric signal passed through the Zener diode 21a, and the F circuit 23 is inverted and the Q
The output of the terminal becomes high level.

Therefore, the voltage drop across the resistor 25a via the capacitor 25 becomes maximum, and the voltage drop across the Zener diode 21b
is conductive, so the lower input of the AND circuit 17 becomes high level. At this time, only when the upper input is at a high level, the output of the AND circuit 17 is also at a high level, so the output amplified by an amplification circuit (not shown) conducts the transistor 10c and is connected to a lamp (desk lamp). ) Turn on 18.

As the charging of the capacitor 25 progresses after about one minute, the voltage drop across the resistor 25a also decreases.
The Zener diode 21b becomes non-conductive.

Therefore, the output of the AND circuit 17 becomes low level, the transistor 10c becomes non-conductive, and the light is automatically turned off. During this time, the lamp 18 is kept on by completing the required operation or by closing the manual electric switch 20 and shorting the AND circuit 17.

Also, if you open the electric switch 20 to turn off the light, the light will go out, and if you make a C- sound at this time, you can turn on the light again for one minute.

The + terminal (non-inverting terminal) of the operational amplifier 15 has
The output of a diode bridge circuit 12 divided by a resistor is input. - terminal (inverted terminal),
A reference DC voltage divided by resistors 14a and 14 is input.

The former are shown as curves 29a, 29b, . . . in FIG. 4, and the latter as a dotted line 30. The outputs of the AND circuit 17 are shown as curves 31a, 31b, .

When the variable resistor 14 is manually increased or decreased, the fourth
Since the dotted line 30 in the figure moves up and down, the curve 31
Since the widths of a, 31b, . . . are changed, the average time during which the transistor 10c is conductive is changed. Therefore, the light 18 can be dimmed.

When the electric switch 20 is closed, the above-mentioned dimming is performed, and when it is opened, the light is turned on at the current brightness for one minute with the C-tone.

In practice, even if the variable resistor 14 is made large, the fourth
It is necessary that the dotted line 30 in the figure is below the upper end of the curves 29a, 29b, .

Without such conditions, the lights would be completely off,
This is because when the electric switch 20 is opened, the C-sound makes it impossible to turn on the light.

The circuit shown in FIG. 5 is for performing the above-mentioned dimming more smoothly. The input side of the operational amplifier 15 in FIG. 2 has been improved.

Terminals 35a and 35b indicate points with the same symbols in FIG. Terminal 36 is connected to the point with the same symbol in FIG.

The transistor 37a is configured to be conductive only in a section slightly smaller than the half wave of the curve 29a in FIG. 4. For this time span, transistor 3
7b is held non-conductive. During this time, the capacitor 38 is charged via the high resistance 39, and the voltage increases almost linearly.

At the end of curve 29a, transistor 37a is non-conducting and transistor 37b is conducting, so that
Capacitor 38 is discharged.

Therefore, the input signal at the + terminal of the operational amplifier 15 becomes curves 32a, 32b, . . . in FIG. 4. The input to the terminal 15b is an electrical signal indicated by the same symbol in FIG. 2, and is therefore shown as a dotted line 33.

The outputs of the output terminal 15a of the operational amplifier 15 become curves 34a, 34b, . . . in FIG. 4. terminal 15
Since the output of a is the upper input of the AND circuit 17 in FIG. 3
It corresponds to the width of 4a, 34b, . . . and can perform dimming.

When the dotted line 33 in FIG. 4 is moved up and down, the curve 34
Since the widths of a, 34b, . . . also change proportionately, the dimming can be effected more smoothly and completely. Returning to FIG. 2, due to the C-tone, the F circuit 23
If you finish your work and want to turn off the light while the Q terminal is at high level, that is, the light is on, make the C- sound again.
Since the Zener diode 21a becomes conductive and the two inputs of the AND circuit 22b both become high level, the output of the terminal becomes high level, and the output of the Q terminal becomes low level, so the Zener diode 21
b becomes non-conductive, the output of the AND circuit 17 also becomes low level, and the light can be turned off.

The Zener diodes 21a and 21b may be used as trigger diodes.

The capacitors 24a and 24b are connected to the AND circuit 22.
This is to ensure stable operation by delaying the input signals of a and 22b for a predetermined period of time.

It is impossible to completely control the lighting described above using the C-tone. For example, when a polyethylene bag is squeezed by hand, a sound wave similar to the C-tone is generated, resulting in an erroneous signal. A creaking sound when a door opens or closes is also a false signal.

Even in such a case, it is effective because it automatically turns off after about 30 seconds to 1 minute.

When the upper surface of the bulging part 1a in Fig. 1 is stroked with the palm of the hand in the direction of arrow A, mechanical resonance occurs, and the size and weight of each part are adjusted so that this vibration frequency includes a frequency of about 5KC or more. is set. Therefore, the internal microphone also resonates, producing an output similar to a C-tone.

Therefore, the same lighting control can be performed, which is effective when it is necessary to avoid making noise.

It is also necessary to avoid reacting to short-lived sound waves, such as the sound of clapping hands, glass tapping, and metal touching.

Transistor 10b is provided to solve the above-mentioned problem. That is, when the C-tone is not input, the transistor 10b is conductive, so the capacitor 11 is short-circuited, and charging due to noise and leakage current is prevented. When the C- tone is input, the transistor 10a becomes conductive and the transistor 10b becomes non-conductive, so that the capacitor 11
Charging is started, and the lighting control described above is performed.

When a small impact sound is input, capacitor 1
1 is charged by a large input energy, the voltage rises rapidly, and the F circuit 23 is activated, resulting in an erroneous signal.

However, since the charging resistor 19 of the capacitor 11 is made large, the capacitor 11 is charged with a substantially constant current by the power source. Therefore, since only the width of the impact sound is detected, the occurrence of false signals is eliminated. Moreover, even if such an impact sound is repeatedly input, each time it disappears, the transistor 10b becomes conductive and short-circuits the capacitor 11, so that it is possible to avoid the integration of the sound into an erroneous signal.

The electric switch 20 and variable resistor 14 in FIG.
The configuration shown in Figure 3 provides convenient means for use.

In FIG. 3, reference numeral 26 indicates a well-known volume control, and the variable resistance 14 can be increased or decreased by rotating a knob 26a from side to side.

When the knob 26a is pressed in the direction of arrow C, the knob 2
The rotating shaft 27 fixed to the switch 6a slides downward, and the actuator 28a of the push-off switch 28
Press. When the pressing force is removed, the knob 26a springs back. Since the electric switch 20 is housed in the switch 28, the electric light 18 repeatedly turns on and off each time the knob 26a is pressed, and when turned left and right, the brightness can be increased or decreased for dimming, which is effective. It can provide a means to do so.

When the light is turned off by the knob 26a, the lighting can be controlled automatically by a C-tone, and it is effective because it can be turned on by the knob 26a like a general lighting equipment.

〔effect〕

To obtain a desk lamp which does not malfunction due to small impact sounds such as the sound of metals touching or the sound of clapping hands, and whose lighting can be controlled by a C-sound.

When the desk lamp is turned off by the electric switch at bedtime, the desk lamp can be automatically converted into a remote control device using C-sound, and is easy to use.

If necessary, the light can be dimmed, and by opening and closing an electric switch, it can perform the same functions as ordinary lighting equipment.
