Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device that controls the lighting state of a discharge lamp by switching the lighting, dimming, and extinguishing states of the discharge lamp. [Prior Art] There is a touch-type switch that uses an induction method of a commercial power supply voltage to control blinking of a stand lighting or the like and control of lighting-dimming-lighting. Specifically, it is a fluorescent lamp stand lighting that uses a touch switch.
Each time the touch sensor is touched by the human body, the lighting state may change in the order of all lighting → dimming → light off → all lighting. For details, see Japanese Patent Application Nos. 63-176573 and 63-17.
It is shown in No. 6574. [Problems to be Solved by the Invention]

[1] In order to switch from dimming to the full lighting state, it is necessary to turn off the light without fail and then switch from full lighting to dimming. In this case, switching from full lighting to dimming requires a half-wave discharge duration or longer to prevent the lamp from going out, and a timer of 2 to 3 seconds is provided.
A timer of about 0.8 seconds is provided to prevent chattering of the touch switch when the mode is switched. During these timer periods, acceptance of touch switch signals is prohibited, and even if the touch sensor unit is touched, the lighting mode is not switched. Therefore, the switching time from full lighting to dimming is about 0.8 seconds, but it takes about 3.6 to 4.6 seconds to switch from dimming to dimming, and there is a problem that the operation feeling is poor.

[2] Switching from full lighting to dimming can be switched by touching the touch sensor unit only once, but switching from dimming to full lighting requires touching the touch sensor unit three times. It is inconvenient to use.

[3] Turning off the light → starting all the lights can be switched by touching the touch sensor unit only once, but starting the light off → dimming lighting requires touching the touch sensor unit twice. ,the above

As described in [1], it takes 2 to 3 seconds to switch from full lighting to dimming, which makes the operation feeling uncomfortable and inconvenient in actual use. Also, as another conventional example, two push-button type switches are used, and one switch blinks the discharge lamp,
There is one that switches between full lighting and dimming with the other switch. In this case, since the state of the switch itself is maintained, the stroke of the switch is large, and there are problems such as poor operation feeling and lack of luxury as a product. In addition, since the commercial AC100V power supply was turned on and off directly to perform the blinking operation, a switch with a large contact capacity or a switch with a high withstand voltage was required, which resulted in high switch cost and switch selection. This has been an obstacle to the miniaturization of switches and the design of products. The present invention has been made in view of the above points, and an object thereof is to provide a lighting device that has a good operation feeling of a changeover switch and is convenient in use. [Means for Solving the Problems] The present invention provides a lighting device that lights a lamp, a first switch that outputs a signal only when operating and switches the lighting and extinguishing of the lamp, and outputs a signal only when operating. The second switch for switching between the full lighting state and the dimming state of the lamp and the second switch when the first switch is in the extinguishing mode or in operation are prohibited from receiving the signal from the first switch. A control circuit is provided which holds a lighting state immediately before extinguishing or a full lighting state or a dimming state by a mode signal and controls lighting of the lamp in a predetermined lighting mode. [Operation] Therefore, when the first switch is in the extinguishing mode or in operation, reception of the signal from the second switch is prohibited, and the lighting mode signal from the first switch causes the full lighting state or the dimming state or The lighting mode immediately before extinguishing is maintained, and the lighting of the lamp is controlled in a predetermined lighting mode. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First
The figure shows a block diagram, and FIGS. 2 to 4 show time charts of the operation. A lighting device A that uses a commercial power supply AC as a power source is configured to light a discharge lamp l, a switch SW ₁ is a switch for switching on / off of the discharge lamp l, and a switch SW ₂ is a discharge lamp l. Is a switch for switching the lighting state of (1) between the full lighting state (F) and the dimming state (D). The switches SW ₁ and SW ₂ are switches that switch signals only during operation. For example, a commercial power induction touch switch or
There is a push switch for small signal circuits that closes contacts only when pushed. Upon receiving the signals from the switches SW ₁ and SW ₂ , the control circuit B switches the states of the switches SW ′ and SW ₂ ′, respectively, and holds the states. That is, each time the switch SW ₁ is operated, the on / off state of the switch SW ₁ ′ is switched, and the discharge lamp 1 is turned on and off. Also,
Each time the switch SW ₂ is operated, the switch SW ₂ ′ is turned on,
The off state is switched, and the discharge lamp 1 is in the dimming state of full lighting. Here, as the operation method of each switch, when the light is off, it is always set to the full lighting (F) state. When it is off, it is always set to the dimming (D) state. ) Is used, one of the three methods is used. In addition, the above ,,
In any of the above methods, the switch SW ₂ ′ is not switched even if the switch SW ₂ is operated when the light is off. While the switch SW ₁ is being operated, even if the switch SW ₂ is operated, it will not operate, and priority will be given to the turning on / off operation of the switch SW ₁ over the simultaneous operation of the switches SW ₁ and SW _2. There is. Next, each case will be described. In the above case, a time chart in this case is shown in FIG. In this case, even if the switch SW ₂ ′ is in the full lighting F or the dimming D state, the switch SW ₂ ′ is always set to the full lighting F when the switch SW ₁ is switched to the unlit state. Further, in the off state, the switch SW ₂ does not operate and holds the full lighting F. Therefore, when the switch SW ₁ is turned on next time, the state of full lighting F is surely brought about. Now, as shown in FIG. 2 (a), when the switch SW ₁ is pressed, the switch SW ₁ ′ is turned on, and the discharge lamp 1 is fully lit F
It becomes a state. When the switch SW ₂ is pressed during the full lighting F, the switch SW ₂ ′ is turned on and the dimming D is set, and when the switch SW ₂ is pressed again, the switch SW ₂ ′ is turned off and the full lighting F is set. As shown in FIG. 2 (a), full lighting F
In the state of, each time the switch SW ₂ is operated, the dimming D and the total lighting F are repeated, and the switch SW ₁ is pressed again,
The switch SW ₁ ′ is turned off and the discharge lamp 1 is turned off. FIG. 2A shows the case where the light is turned off during the dimming D, and FIG. 2B shows the case where the light is turned off during the full lighting F. However, whether the switch SW ₂ ′ is in the full lighting F or the dimming D, the switch SW ₂ ′ is always set to the full lighting F when the switch SW ₁ is switched to the unlit state.
Further, as shown in FIG. 2 (c), after the lighting switch SW _1, immediately to switch the dimming D state from the full lighting F, when operating the switch SW _2, the mode switches SW ₂ ' However, similarly to the conventional example, when the lighting device A is provided with the timer time t ₁ in order to avoid the full lighting F → dimming D switching during the half-wave discharge duration, the timer time t After _one , the lighting state will switch from full lighting F to dimming D. Next, the case of will be described. In contrast to the method of, when the switch SW ₁ is turned off,
W ₂ ′ is always set to the dimming D state. Further, in the off state, the switch SW ₂ does not operate and holds the dimming D state. When lighting with switch SW ₁ , be sure to use switch S
Although W ₂ ′ starts in the dimming D mode, if the tie time t ₁ is set in the lighting device A as described above, the lighting state is changed after t ₁ as shown in FIG. All lights F
→ Switches to dimming D. FIG. 3 (a) shows a case in which the light is switched to light control D → all lighting F → light control D ... After turning on, and the light is turned off in the state of light control D, and FIG. 3 (b) shows the light control D. It shows a case where the state is switched to the full lighting F and the lights are turned off in the state of the full lighting F. However, as described above, in this method, when the switch SW ₁ is turned off, the switch SW ₂ ′ is always set to the dimming D state. Therefore, as shown in FIG. 3, when the switch SW ₁ is turned on next time, the switch SW ₂ ′ always starts in the dimming D mode, and after t _{1 of} the timer period, all lights F → dimming D. It switches to. Next, the case of the method will be described. This method is a method of holding the lighting mode immediately before turning off when the light is turned off. First, as shown in FIG. 4 (a), the switch SW ₁ is operated to turn on the switch SW ₁ ′ to turn on all lights F, and then the switch SW ₂ is operated to adjust dimming D → all lights F → Switch to ... and switch SW ₁
Operate to turn off the light. At this time, the switch SW ₂ ′ is kept in the state of full lighting F, and when the switch SW ₁ is turned on again, the lighting state becomes the state of full lighting F as shown in FIG. 4B. Then, when the switch SW ₁ turns off the light in the state of switching to the dimming D state, the switch SW ₂ ′ is held in the state of the dimming D. When the switch SW ₁ is turned on again, the lighting state becomes the dimming D state as shown in FIG. 4 (c). However, when the lighting device A is set to t ₁ of the tie period, the dimming state is set after t _{1 in the same} manner as described above. Even if the switch SW ₂ is operated immediately after lighting with the switch SW ₁ , if the lighting device A has the timer period t ₁ , the mode of the switch SW ₂ ′ is switched,
The lighting state does not change until after t ₁ . The control circuit C shown in FIG. ₁ operates the buzzer BZ or the like that generates sound when the switches SW ₁ and SW ₂ are operated, and visually confirms the state of full lighting F or dimming D of the switch SW ₂ ′. This is a circuit for turning on or off the light emitting diode LED in accordance with the mode of the switch SW ₂ ′ in order to display the light. Further, the lighting or extinguishing mode of the switch SW ₁ ′ may be displayed by another light emitting diode. Also,
Other light emitting devices may be used instead of the light emitting diode. In this way, switch SW ₁ for switching on and off,
All lighting F Dimming D switch SW ₂ is used separately, so all lighting F → dimming D, dimming D → all lighting F
The switch to can be performed only by operating the switch SW ₂ once, the switching time is short, it is convenient to use, and the operation feeling is good. Also, the method of starting by turning off the light → dimming is the switch SW
It is possible in _one single operation. When the mode immediately before the light is turned off is the full light F with the method of and the method of switch SW ₁ →
It is necessary to operate the switch twice in the order of the switch SW _2. However, as in the conventional example, there is no period for which the changeover switch of light OFF → lighting F → dimming D is prohibited, and the switch SW ₂
Operates, and even if the lighting device is provided with a timer period t _{1 and} the lighting state of the discharge lamp does not change during the period t ₁ , a buzzer sound or a switch using a light emitting diode is activated according to the operation of the switch SW _2. the ability to display the operating status of the SW _2, even if the operation of the full lighting F → dimming D change-over switch, nothing bad and the operation feeling that there is no change, the frustrating feeling during operation is eliminated. In the case of the above method, since the mode immediately before being turned off is retained, when it is customarily used in the state of full lighting F or dimming D, it is necessary to set to the full lighting F or dimming D mode every lighting. No, it is convenient to use. Furthermore, using a switch that outputs a signal to the switches SW ₁ and SW ₂ only during operation, the control circuit blinks or lights up all the signals,
An electronic switch such as a touch switch or a photoelectric switch can be used as a switch to switch the dimming state, and a lighting device with a good operational feeling and a high-class feeling can be provided. In addition, even if a mechanical switch is used as the switch, a switch with a low withstand voltage and a low capacity can be used, and a switch that is small in size, low in cost, and has a good operation feeling can be selected. The degree of freedom in design is also increased. Also, when the switches SW ₁ and SW ₂ operate simultaneously,
Since priority is given to turning on and off of SW ₁ , even if the switches are operated by groping in the dark, even if they are accidentally operated at the same time, it is possible to give the highest priority to switching from off to on, which is the first purpose. Next, a specific example of the control circuit will be described. FIG. 5 shows the method of, which is a case of the method of holding the mode immediately before turning off the light. The example shown in FIG. 5 is an example using two commercial power supply type touch switches. The operation of the touch switches and the lighting device A for the discharge lamp 1 are described in Japanese Patent Application No.
It is the same as the contents described in -176573 and Japanese Patent Application No. 63-176574. The input terminal T ₁ is a terminal for receiving the input signal of the touch switch of lighting / lighting (lighting off)
T ₂ is a terminal that receives an input signal of the touch switch for full lighting / dimming. Further, the lighting device A receives a lighting / dimming signal from the output terminal CUT ₁ and a full lighting / dimming signal from the output terminal OUT ₂ , and turns off when the terminal OUT ₁ is at the H level, and the terminal OUT ₁
Lights up when is at L level, dimming when terminal OUT ₂ is at H level,
It operates so as to be fully lit when the terminal OUT ₂ is used. For example, a fluorescent lamp lighting device using an inverter or the like is used. Further, the lighting device A may have a tie that prohibits switching to dimming during continuous half-wave discharge in order to prevent the discharge lamp 1 from extinguishing at the time of starting. The touch detection circuits 1 and 2 for detecting that the human body touches the terminal T ₁ or T ₂ by the touch switch are configured by using the inverters IC ₁ and IC _4, and when the human body touches the terminal T ₁ or T _2. ,
The output of the inverter IC ₁ or IC ₄ changes from H level to L level. The output of the inverter IC ₁ or IC ₄ is
Inverted by IC ₂ or IC ₅ , D flip-flop IC ₃
Alternatively, it is input to the clock input CK of IC ₆ . Therefore, terminal T
Every time the human body touches ₁ or T ₂ , the D flip-flop IC ₃ or
The output Q of the IC ₆ will be inverted, and a switching signal for turning on / off and dimming all lights will be output from each output. Here, the diode D ₁ is a priority circuit of the blinking touch switch, and works so as to inhibit the reception of the input signal of the terminal T ₂ when the human body is touching the terminal T ₁ . Diode D
₂ inhibits the reception of the input signal of the terminal T ₂ when the extinguishing signal is output, and works so as not to switch the all lighting / dimming signal output. The timer circuit 3 determines the ringing time of the buzzer BZ, and is composed of gates IC ₈ and IC ₉ , a resistor R ₁ , a capacitor C _{1 and the} like. Buzzer ringing circuit 4 is inverter IC ₁₀ , IC
₁₁ , Buzzer BZ, etc., when there is an input to the terminal T ₁ or T ₂ , the timer circuit 3 keeps the buzzer BZ for about 40 msec.
Is set to ring. A lighting circuit 5 including a gate IC ₇ , a light emitting diode LED, a transistor Tr _{1 and the} like displays the lighting state of the discharge lamp l, and the terminal OUT ₁ is at L level.
Only when the terminal OUT ₂ is H level (dimming state) in the level (lighting state), the output of the gate IC ₇ becomes the H level, the transistor Tr ₁ is turned on and the light emitting diode LED is lit, and dimming is performed. You can confirm that it is in a state. Further, the D flip-flop IC, regardless of the status of the terminal OUT _1, unless the input to the terminal T ₂ are, terminal OUT ₂
Holds the state of H level or L level. Therefore, when the terminal OUT ₁ changes from the L level to the H level by the input from the terminal T ₁ and the discharge lamp 1 is extinguished, the terminal OUT ₂ holds the mode immediately before extinguished. The reset circuit 6
Is for resetting the D flip-flops IC ₃ and IC ₆ when the power is turned on. A terminal T ₁ of the touch input for a point / flashing as described above, since the terminal T ₂ of the touch input for full lighting / dimming provided separately,
All lighting → dimming switching, and dimming → all lighting switching operation,
Since it can be done by one touch operation on the terminal T ₂ , it has a good operation feeling and is convenient in use. In addition, when touch input of terminals T ₁ and T ₂ , buzzer BZ 40ms
Ringing for ec, and only in the dimming state when lighting,
Since the light-emitting diode LED is turned on to indicate the total lighting state and the dimming state, the lighting mode at the start of lighting can be immediately identified. It can also be confirmed that the touch switch has operated. In addition, even if the lighting device A has a timer that prohibits switching of all lighting → dimming during half-wave discharge at startup, the timer time
If you touch the touch input of the terminal T ₂ during t ₁ , the buzzer sound and light / emission switching of the light emitting diode will be performed, and you can check the mode switching operation by the touch switch, even if you touch the touch input as before. The uncomfortable feeling of not operating will be improved. In addition, since the previous mode is held when the lamp is turned off, it is convenient to use, since it is not necessary to set the mode each time the lamp is turned on when it is always used for full lighting or dimming. Next, FIG. 6 shows a concrete example of the method (2), that is, the method of simply setting the light control state when the light is turned off. This embodiment is an example in which two commercial power source induction type touch switches are used, and the operation of each circuit is the same as in the case of FIG. However, when the output terminal OUT ₁ goes high due to the signal from the touch input terminal T ₁ , the D flip-flop is turned off.
An H level signal is input from the output of IC ₃ through the diode D ₃ to the reset circuit 6 of the D flip-flop IC ₆ . When the MN4013 or the like is used as the D flip-flop of IC ₃ and IC ₆ , the output of the IC becomes H level when the set input S is at L level and the reset input R is at H level. The output of the IC ₆ becomes H level, therefore the terminal OUT ₂ becomes H level, and the dimming mode is always set when the light is turned off. Next, a specific example of the method (2), that is, the method of always setting the all-lighted state when the light is turned off will be described. FIG. 7 shows an example using two commercial power source induction type touch switches, and the operation of each circuit is the same as that of the embodiment of FIG.
However, when the output terminal OUT ₁ becomes H level due to the signal of the input terminal T _{1 and} the light is turned off, a signal for setting the set input S to H level is input from the output of the D flip-flop IC ₃ to the D flip-flop IC ₆ . I am trying to do it. As in the previous embodiment, the MN40 is used as a D flip-flop for IC ₃ and IC _6.
When using 13 etc., the logic mode of the IC is
When the level and reset input R are L level, the output is L
Since it becomes the level, the output of the D flip-flop IC ₆ becomes the L level, therefore the terminal OUT ₂ becomes the L level, and the all-on mode is always set when the light is turned off. FIG. 8 shows an embodiment in which push switches SW ₁ and SW ₂ are used instead of the touch switch. The circuit operation is the same as in FIG. As a specific example of the switches SW ₁ and SW ₂ ,
A surface switch using conductive rubber used for card-type calculators and the like can be used. FIG. 9 shows an example when there are n switching outputs in the lighting state. The input switches SW _{1 to} SW _{(n + 1)} are push switches as in the previous embodiment. The other circuit operations are the same as those of the embodiment shown in FIG. 5, and n circuits for all lighting / dimming switching in the embodiment of FIG. 5 are arranged. The D flip-flops IC _{62 to} IC _6n are the same ICs as the D flip-flop IC ₆ . Also, the gate IC ₈ is n + 1
The input NOR gate is used. [Effects of the Invention] As described above, the present invention provides a lighting device for lighting a lamp, a first switch that outputs a signal only when operating, and switches the lighting and extinguishing of the lamp, and outputs a signal only when operating. The second switch that switches between the full lighting state and the dimming state of the lamp and the second switch is prohibited from receiving the signal of the second switch when the first switch is in the off mode or in operation, and the lighting from the first switch is performed. Since the control circuit controls the lighting of the lamp in a predetermined lighting mode by holding the all lighting state, the dimming state, or the lighting mode immediately before being turned off by the mode signal, the first switch is turned on or off. When it's in the middle, the reception of the signal of the second switch is prohibited,
By controlling the lighting of the lamp in a predetermined lighting mode by holding the lighting mode of all lighting, dimming status, or lighting status immediately before turning off by the lighting mode signal from the first switch,
For example, conventionally, when switching from dimming to full lighting,
Compared to performing several operations, one operation from dimming to full lighting mode is required by operating the second switch, and when lighting the lamp, the full lighting state or dimming It can be performed in the lighting state or in the lighting mode immediately before turning off. In this way, the lamp can be turned on in any lighting mode with a few switch operations, and the operation feeling of the changeover switch is good, convenient for use. It has the effect of being In addition, since the first switch for switching between lighting and extinguishing is predominantly operated, when the switches are groped in the dark, even if they are simultaneously operated by mistake, the first purpose is to switch from extinguishing to lighting. The lamp can be reliably turned on. In addition, by providing a display element that indicates that according to the operation of the second switch and a sound generation device that generates a sound at the same time as the operation of both switches, it is possible to match the operation of the second switch. The operation state of the second switch can be confirmed by visual or visual display.
