Description

[Detailed description of the invention] [Industrial application field] This invention is a remote control that lights up a hand-held desk lamp for a set time using human voice, and also stops the lamp while it is on by using the same voice. It is used as a control device. Furthermore, a device has been added that allows free manual control of the illuminance. [Prior Art] Examples of the conventional art include Utility Model Application Publication No. 58-50637 and US Pat. No. 4,433,362 by the same inventor. [Problems to be solved by the present invention] First, in the conventional technology, a remote control device is built into the main body of a desk lamp or similar lighting equipment, It is necessary to purchase new lighting equipment. Therefore, there is an inconvenience that the desk lamp that is on hand becomes useless. Secondly, when controlling the lighting using the above-mentioned conventional technology, it is convenient to use that the lighting time can be extended to about 1 minute and the lighting can be turned off in the middle.
However, there are problems that remain unresolved. Thirdly, when the light is turned on by the sound of a hissing sound, which is a resonant fricative sound of air passing between the roof of the mouth and the tongue,
Suddenly turning on a 100 watt light bulb will dazzle your eyes, so it is necessary to adjust the brightness to suit each individual, but this has become a problem. Fourthly, it is desirable to be able to freely adjust the brightness manually when the lamp is turned on. Although there are products of this type on the market today, there is a problem with remote-controllable lighting fixtures that are not included. [Means for solving the problem] A remote control device is housed in a tabletop-like case, and by inserting the plug of a desk lamp into it, a resonant fricative sound (hereinafter referred to as C-sound) is produced. ), the first problem is solved by controlling the lighting of the desk lamp. Using an electric 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 plug of the desk lamp is inserted into an outlet), and the flip-flop circuit is inverted by the detection signal of the C sound. This signal activates the switching element to energize the desk lamp light bulb, and the electric signal obtained after energizing for the set time reverses the flip-flop circuit again to stop energizing the light bulb. . Furthermore, 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 second 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 third problem. When the light is turned on by the manual switch, the brightness of the light can be freely adjusted using the above-mentioned means, which solves the fourth problem. [Operation] By using the means described in the previous section, it is possible to control the lighting of a handheld desk lamp by remote control. Similarly, by using 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. Also, when the errand is finished within that time, the C- sound is generated again and the light is turned off. Also, 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 sound. 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 a manual electric switch, by changing the variable resistor, the average time of energization can be changed, and the light can be controlled using a 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. 1a is an explanatory diagram of an apparatus for controlling the lighting of a hand-held desk lamp by remote control (in the case of this embodiment, it is configured as a table tap), which is an embodiment of the device of the present invention. In FIG. 1a, the housing 1 is a well-known table tap made by plastic molding.
Cord pulled out (conductor wire for AC current) 1
A plug 1a is provided at the end of b, and is inserted into an indoor outlet to supply alternating current. A manual knob 26a is attached to the top surface of the housing. As will be described later, the manual knob is used to change the brightness of the desk lamp and to turn it on and off. Similarly, a microphone (indicated by symbol 6 in FIG. 2) is provided on the back side of the hole indicated by symbol 6a on the upper surface to receive sound waves. The plug of a handheld desk lamp is inserted into the outlet 2 in the direction of arrow A. The outlets 2a, 2b, and 2c on the top surface of the housing 1 are plugged with outlets for other electrical appliances as needed, and AC power is supplied through the plug 1a. The lighting of the desk lamp plugged into the outlet 2 is controlled by the sound waves from the microphone 6.
Moreover, the light adjustment and extinguishing of the light are controlled by a manual knob 26a. What is shown in Figure 1b is the code /
b, plug 1a and outlets 2a, 2b, 2c
This is an example in which the is removed. Alternating current is supplied by inserting the two conductor pieces 3a protruding from the housing 3 into an indoor outlet. A microphone 6 is provided on the back side of the hole 6a, and the lighting of a desk lamp plugged into the outlet 4 can be controlled using the received sound waves. Further, by operating the manual knob 26a, the light of the desk lamp can be adjusted and turned off. The present invention can also be implemented by means of controlling only the light using the manual knob 26a and turning on and off the desk lamp using a separate electric switch. FIG. 2 shows an electric circuit for controlling the energization of a light bulb in a desk lamp using the above-mentioned members. This invention does not use a special sound source,
The purpose is to obtain a device for remotely controlling the lighting of a desk lamp by utilizing a special human generating 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 the user forgets to carry the item with him/her due to carelessness, the 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. 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 changing the diaphragm of the microphone,
If configured to resonate only with sound waves of KC or higher,
High-pass filter circuit (capacitor 8a, resistor 8
b) 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, amplifier circuit 7, etc. The above-mentioned C sound detection signal is transmitted by 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 and 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 Q is at high level, the upper input of AND circuit 22a is also at high level. Therefore, the output of the AND circuit 22a temporarily becomes a 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 amplifying circuit (not shown) conducts the transistor 10c and is connected to a light bulb (a 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 light bulb 18 is kept lit 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, it will turn off, and if you make a C sound at this time, it will turn on 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. A reference DC voltage divided by resistors 14a and 14 is input to one terminal (inverting terminal). The former is shown in FIG. 4 by curves 29a, 29b, . . .
, the latter is shown 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
The widths of a, 31b, . . . are changed. Therefore, the average time that transistor 10c is conductive is changed. Therefore, the light bulb 18 can be dimmed. When the electric switch 20 is closed, the above-mentioned dimming is performed, and when the electric switch 20 is opened, the light is turned on at the current brightness for one minute with a C sound. In practice, even if the variable resistor 14 is made large, the fourth
It is necessary that the dotted line 30 in the figure be below the upper ends 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 intended to more smoothly perform the above-mentioned dimming. 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 slightly short half-wave section of the curve 29a in FIG. 4. For this period of time, transistor 3
7b is kept non-conductive. During this time, the capacitor 38 is charged via the resistor 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 to 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 output of the output terminal 15a of the operational amplifier 15 becomes the curves 34a, 34b, . . . in FIG.
Since the output of transistor 5a is the upper input of the AND circuit 17 in FIG. It corresponds to the width of 34a, 34b, . . . and can be dimmed. When the dotted line 33 in FIG. 4 is moved up and down, the curve 34
Since the widths of a, 34b, . Returning to Figure 2, due to the C sound, F circuit 2
When the errand is finished and you want to turn off the light while the Q terminal of 3 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 C-tone. For example, when a polyethylene bag is squeezed with one's hands, a sound wave similar to a C sound is emitted, 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 light turns off automatically, the Zener diode 21
Since the output of b has been converted to a low level, the output of the inverting circuit 21c becomes a high level, and this output is inverted by energizing the R terminal of the F circuit 23 via the differentiating circuit 21d. Therefore, the output of the terminal of the F circuit 23 becomes high level, and the lighting of the light bulb 18 can be controlled in response to the input of the next C sound. Furthermore, when the power is turned on, that is, when the plug 1a in Fig. 1 is inserted into an outlet and AC power is supplied to the circuit in Fig. 2, the inverting circuit 21c is also supplied with power, and its output becomes high level. The R terminal of the F circuit 23 is energized so that lighting control for C-tone can be performed. 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 sound 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 sound is input, the transistor 10a becomes conductive and the transistor 10b becomes non-conductive, so that the capacitor 1
1 charging is started, and the lighting control described above is performed. According to the technique described in Japanese Utility Model Application No. 58-50637 cited in the section of the prior art, the charging current of a capacitor corresponding to the capacitor 11 corresponds to the magnitude of the C sound. Therefore, when there is a small impact sound input, the capacitor is charged by the large input energy,
The voltage rises rapidly, activating the F circuit 23 and generating an erroneous signal. However, in this embodiment, 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 supply. Therefore, since only the width of the impact sound is detected, the occurrence of false signals is eliminated. Even if such an impact sound is repeatedly input, each time it disappears, the transistor 10b
conducts and short-circuits the capacitor 11, which has the effect of avoiding erroneous signals from being integrated. 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 denotes a well-known volume control which can increase or decrease the variable resistance 14 by rotating a manual knob 26a left and right. 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 is possible to 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 sound, and it is effective because it can be turned on by the knob 26a like a general lighting equipment. The manual knob 26a is shown with the same symbol in FIGS. 1a and 1b. The circuit shown in Fig. 2 is housed inside the casings 1 and 3 shown in Figs. By inserting the conductor piece shown in the figure into an indoor AC power outlet, power is supplied from the AC power supply 16 to the circuit shown in FIG. 2 inside the housing. Furthermore, the plugs of the desk lamps in hand can be inserted into the outlets 2 and 4 shown in FIGS. 1a and 1b to control the lighting of the light bulbs. Therefore, the light bulb 18 of the desk lamp in FIG.
is supplied with power from the above-mentioned outlet, and lighting control is performed using the C sound. The outlets 2a, 2b, and 2c shown in FIG. 1a are directly supplied with power from the AC power source 16 shown in FIG. As mentioned above, the device of the present invention may be activated by an erroneous signal and turn on for about one minute. At this time, if a child or the like carelessly inserts the plug of the electric heater into the outlet 2 or 4 shown in FIGS. 1a and 1b, it is dangerous if there is flammable material on it. It is also dangerous for children to touch. In order to prevent the above-mentioned problem, it is preferable to add means such as tightening a part of the plug with a screw so that the plug does not easily come off after the plug of the desk lamp is inserted. [Effects] As described in the embodiment, lighting of a handheld lighting fixture such as a desk lamp can be controlled by the C sound. To obtain a desk lamp which does not malfunction due to a small impact sound such as the sound of metal touching or the sound of clapping hands, and whose lighting can be controlled by a C sound. When the desk lamp is turned off with the electric switch at bedtime, the desk lamp can be automatically converted into a remote control device using a 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.
