Abstract

PURPOSE:To improve operating performance with one operating switch by setting a specific lighting mode in a control circuit which controls a switch so that lag switching operation can be conducted after this lighting mode. CONSTITUTION:When a switching signal is input in a specific lighting mode state, lag switching operation of switching an open/close mode of the contact of a switch 20 is performed after the lapse of a certain time. The switching signal of a switch 12 is input to a contact control circuit 13 which controls the opening/closing of the contacts 110-112 of the switch 20 and inputs a lighting mode switching signal 200 to a lag time control circuit 14 which outputs a lag switching mode signal 300 to a contact control circuit 13 and outputs a lag condition signal 310 to a lag condition display section 15. It is thus possible to switch a lighting mode after some time interval by the switching operation of one switch 12.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lighting switching device that controls lighting modes of lighting to be switched with a delay by switch operation.

[Conventional technology]

As shown in FIG. 2, in the conventional device, a switch 21 is provided in front of a normal lighting changeover switch 22, and the contacts of the switch 21 are opened and closed separately from the lighting changeover switch 22 to switch the lighting mode. There is. Switch 21 is auxiliary power supply 1
When the contact of the switch 17 of the control circuit section 16 that is supplied with power and operated by the control circuit 16 is closed, the control circuit 16 closes the switch 2
The first contact closes and power is supplied to the circuits after the lighting changeover switch 22. When the contacts of the switch 21 are closed,
By rotating the contacts of the lighting changeover switch 22, the lighting mode is switched in the following order: two fluorescent lamps 5, 6 are turned on, one fluorescent lamp 6 is turned on, the small incandescent lamp 8 is turned on, and all the lights are turned off.

Here, when the contact of the switch 17 of the control circuit section 16 is opened in the lamp lighting mode, a contact open signal is sent from the contact control circuit section 16 to the switch 21 for a certain period of time, and the contact is opened. As a result of this operation, the lamp that had been on until now loses power and goes out, and after a certain period of time has passed after the switch is operated, the lighting mode is switched.

[Problem to be solved by the invention]

The above-mentioned conventional technology requires two switches, one for switching the lighting mode and the other for switching the lighting mode with a delay, and does not give consideration to operability.

An object of the present invention is to improve operability by using only one operation switch, and also to enable delayed switching of lighting modes in addition to normal switching of lighting modes. Furthermore, it is intended to enable adjustment of the switching delay time and to display the state at the time of delayed switching. Another objective is to enable delayed switching operations in any lighting mode.

[Means to solve the problem]

In order to achieve the above object, a specific lighting mode is set in the control circuit that controls the switch, and the switching operation is delayed after this lighting mode.

Further, in order to adjust the delay time, a timer for setting the time is provided, and a display section having a light emitting diode or a light bulb is provided to display the delay switching state.

Furthermore, the control circuit is provided with a mode designation function in order to perform a delayed switching operation in any lighting mode.

[Effect]

When the control circuit receives a switching signal while in a specific lighting mode, the control circuit performs a delayed switching operation of switching the opening/closing mode of the contacts of the switch after a certain period of time has elapsed.

In addition, the delay time can be adjusted by partially adjusting the timer for setting the delay time, and when the delay is switched, the light emitting diode or light bulb in the display section is turned on, so that it can be seen that the delay is being switched.

Furthermore, since the specific mode of the control circuit can be specified and the specific mode can be reset, it is possible to perform the delayed switching state in any mode.

〔Example〕

Embodiments of the present invention will be described below with reference to FIG.

In FIG. 1, one end of the power supply 1 is the contact 11 of the switch 20.
0,111,112, contact 110.1
11 and 112 are connected to a small incandescent light bulb 8 and a ballast 32, respectively. One end of ballast 2.3 is fluorescent light 4
．． 5, and the other end of the filament is connected to the other filament via glow star taro, 7. The remaining filament end of the fluorescent lamp 4.5 and the small incandescent lamp 8 are connected to the other end of the power supply 1. The open/close signal of the switch 12 is converted into a voltage signal 210 by the switch signal section 11 and input to the contact control circuit 13. The contact control circuit 13 is connected to contacts 110 and 111 of the switch 2o.
．． 112 and delay time control circuit 1
A lighting mode switching signal 200 is input to 4. The delay time control circuit 14 outputs a delay switching mode signal 300 to the contact control circuit 13 and also outputs a delay state signal 310 to the delay state display section 15. Further, the auxiliary power supply circuit 1o connected to the terminal of the power supply l includes a switch signal section 11, a contact control section 13
, the delay time control circuit 14, and the delay state display section 15.

The operation shown in Figure 1 is that when the power supply 1 is turned on, the contact control circuit 1
The mode signal initialized in step 3 is input to the switch 20, and the contacts 110, 111, and 112 are opened and closed according to the initial mode. Here, when the contact of the switch 12 is closed, a pulse voltage signal 210 is input from the switch signal section 11 to the contact control circuit 131, and in the contact control circuit 13, when the pulse voltage signal 210 is input, the switch is switched to switch the lighting mode. 20 changes and the control signal to contact 110.
The opening/closing mode of 111 and 112 changes and the lighting mode changes. By opening and closing the switch 12, four lighting modes are sequentially repeated: two fluorescent lamps 4.5, one fluorescent lamp 4, one small incandescent lamp 8, and all lights lit. Further, the contact control circuit 13 switches the lighting mode and inputs the lighting mode switching signal 200 to the delay time control circuit 14. In the delay time control circuit 14, when the lighting mode switching signal 200 is input, it is determined whether the mode is set or not. Then, when the next lighting mode switching signal 200 is inputted, the device enters a delayed switching mode state and outputs a delayed switching mode signal 300 to the contact control circuit 13. The contact control circuit 13 maintains the lighting mode before the lighting mode switching signal 200 is output while the delayed switching mode signal 300 is input. This delay switching mode signal 30
O is output for a time set in a part of a timer inside the delay time control circuit 14. In this delay switching mode state, the delay time control circuit 14 further controls the delay state display section 1.
The delay state signal 310 is output to the delay state display section 15.
Then, while the delay state signal 310 is being input, a light emitting diode or a light bulb is turned on to indicate to the outside that the delay switching mode is present. When the delay switching mode state ends, the delay switching mode signal 300 is output from the delay time control circuit 14.
The delay state signal 310 stops, and the contact control circuit 13 sends the next lighting mode signal to the switch 20, and the lighting mode of the lamp changes. .

Here, the time of a part of the timer inside the delay time control circuit 14 is determined by the frequency of the oscillator, and the time can be adjusted by changing this frequency. Further, a specific lighting mode for determining the delay switching mode can be determined by switching the mode setting of the delay time control circuit 14.

Next, a more detailed explanation will be given using FIGS. 3 and 4. The circuit configuration in FIG. 3 is the same as in FIG. 1, which includes a power source 1, a switch 20 with contacts 110, 111, and 112 that control the flow of current to the lamp, and a glow starter, a filament at both ends,
A lamp lighting circuit is constituted by a fluorescent lamp 4.5 connected through a ballast 4.5, a ballast 2.3 paired with it, and a small incandescent lamp 8, and an auxiliary power supply circuit 10, a switch 12, a switch signal section 11, Contact control circuit 13 and delay time control circuit 14 that control opening and closing of contacts 110, 111, and 112 of switch 20
and the delay status display section 15 constitute a switching device.

The operation in FIG. 3 is that when the power supply 1 is turned on, in the auxiliary power supply circuit 10, the power supply limited by the impedance of the capacitor charges the capacitor 41 via the diode 50, and the voltage across the capacitor 41 is transferred to the Zener diode 55. This makes the voltage constant and the power supply to the switching device roars.

The diode 51 functions to allow a reverse current to flow in order to prevent DC charges from being accumulated in the capacitor 40. When the voltage of the capacitor 41 rises, current flows to the resistor 31 via the capacitor 42, and a D flip-flop (hereinafter referred to as F) is activated.
F.) 80 R1 and F.

A differential voltage waveform is applied to S of F and 81, and F.

F, 80 is reset, D, F, F, 81 is set. Therefore, N0R85,86 and 0R87,88,
All outputs of 89 become L, transistor 60.61.6
2 is OFF and no current flows through the excitation windings 70, 71, 72 of the relay, so the contacts 110, 111 of the switch 20
．． 112 is opened and enters all-lights-off mode. here,
When the switch 12 is closed and opened once, the voltage across the capacitor 43 changes from H to L-H, and a pulse voltage is generated at the output of the inverter 82. Due to this pulse voltage, F.

F, 80 is set, and D, F, F, 81 remains set. Thereafter, each time a pulse voltage is applied to C□ of D, F, F, and 80, the mode changes as shown in FIG. 4, and changes to the original mode at the fourth time. In addition, transistors 60, 61, and 62 are turned ON and OFF in each mode using the logic circuit consisting of N0R85, 86 and 0R87, 88, 86 to sequentially repeat the lighting mode shown in Figure 4. .

Here, the output of N0R85 is a signal that controls lighting of the small incandescent light bulb 8, and when switching from the small incandescent light bulb lighting mode to the all lights off mode, the output of this N0R85 changes from H to L. This change is input to the inverter 83 via the switch 100, and this output is sent to the capacitor 4.
4. Since it is input to the inverter 84 via the resistor 35, a negative logic pulse voltage that changes from H to L is input to the timer IC 91 at the output of the inverter 84. The timer IC 91 is an IC (for example, Matsushita AN6780) that divides a frequency determined by an external resistor 38 and a capacitor 45 and outputs an output for a certain period of time. The capacitor 45 is CT (μ
F) T=11.3XRT XCT. The output of this timer IC91 is inputted to 0R87 via AND90 and switch 101. Therefore, while the output of timer IC91 is H, the output of N0R85 is L.
However, the output of 0R87 becomes H, and the small incandescent light bulb 8 enters the lighting state, and as a result, while the output of the timer IC 91 is H, the small incandescent light bulb 8 lighting mode is maintained, and then the small incandescent light bulb 8 remains in the delayed switching mode. Furthermore, the output of AND90 is connected to the base of transistor 630 of delay status display section 15,
While the output of the timer IC 91 is H, a delay state signal is input to the transistor 63, and the light emitting diode 56 continues to emit light in the delay switching mode.

Switches 100 and 101 are used to change the setting of the lighting mode, which is a delayed switching mode, and the right side of each switch performs the delayed switching operation of the small incandescent bulb 8, the middle one performs the delayed switching operation of the fluorescent lamp 5, and the left side performs the delayed switching operation of the fluorescent lamp 4. At the terminal, the lighting modes are set to a small incandescent light bulb lighting mode, a secondary lighting mode, and a single lamp lighting mode, respectively, as delayed switching modes.

Note that when the switch 75 is open, H is input to the input terminal of the AND90, so the output of the timer IC91 can be directly used as the output of the AND90.
When is closed, L is input to one end of the input of AND90, so the output of AND90 is fixed at L, and the delay switching mode is in a stopped state.

According to this embodiment, it is possible to completely stop the operation in which the 1 lighting mode is switched after a fixed time delay from the operation of the switch 12.

〔Effect of the invention〕

According to the present invention, since it is possible to switch the lighting mode with a delay by a switch operation using one switch, there is an effect that the lighting mode can be delayed by a simple switch operation.

In addition, since the delay time is changed by changing the constant of the resistance of the oscillation circuit, it is possible to set the delay time arbitrarily, and the light emitting diode is turned on during delay switching mode, so it is possible to set the delay time as desired. There is an effect that can be determined.

Furthermore, since the lighting mode that becomes the delay switching mode can be easily switched using a switch, there is an effect that a delay operation can be performed in any lighting mode.
