Abstract

PURPOSE:To sufficiently make a switchover from lighting a miniature electric bulb to entire lighting-up only at one time opening and closing operation by having a first switching means for switching a lighting condition over to N-step conditions through the operation of operating members, and a second switching means for switching a lighting condition from the N-step conditions to N-1 step ones excluding a light-extinguished one in operative association with opening and closing a power source circuit for a floodlight. CONSTITUTION:When a pull string 26 or the like provided to a lighting system is operated, a first switching means is actuated to switch a lighting condition over to such N-step conditions including a light-extinguished condition as, for example, making sequential switchovers from entire lighting-up to light-adjusted lighting, thence to lighting a miniature electric bulb and extinguishing the lighting system, and back to the entire lighting-up. The lighting system may be extinguished accordingly even through the operation of the pull string or the like. When a power source circuit 2 on the other hand is opened and closed through the operation of a wall switch 9 or the like, a second switching means is actuated to switch a lighting condition over to such N-1 step conditions excluding the light-extinguished condition as making sequential switchovers from entire lighting-up to light-adjusted lighting, thence to lighting the miniature electric bulb and back to the entire lighting-up. It may consequently require such simple operations as lighting the miniature electric bulb extinguishing the lighting system (opening the wall switch) and entirely lighting the lighting system to make a switchover from lighting the miniature electric bulb to the entire lighting-up by use of the ordinary wall switch 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a lighting device in which the lighting state can be changed by operating a pull string or the like and at the same time by opening and closing a power supply circuit.

[Conventional technology]

A lighting device equipped with a switching means for switching the lighting state in a predetermined order in conjunction with opening and closing of a power supply circuit by a wall switch or the like is known from Japanese Patent Publication No. 55-5840.

Further, a lighting device is also known in which the lighting device is provided with a switch that opens when a pull string is pulled and closes when released, and the switch is connected to the power supply circuit.

Such a lighting device has the feature that the lighting state can be changed by either opening/closing the power supply circuit using a wall switch or the like, or by operating a pull string.

[Problem to be solved by the invention]

A normal wall switch is the most practical means of opening and closing a power circuit, but whereas a wall switch can turn off the light by itself, a switch that closes when you pull the pull cord and release it does not have the function of turning off the light.

Therefore, if the switching means were to operate in three stages, such as full lighting - dimming lighting, one bulb lighting -> full lighting, there would be an inconvenience that the lights could not be turned off by operating the pull string. On the other hand, if it is a four-step operation that includes the lights-off stage of all lights on - dimming, one light bulb on, lights off, and all lights on, when switching from light bulbs on to all lights on with a wall switch, the light bulbs on - lights off. A complicated operation is required: (Wall switch off) → Lights off (Wall switch person) → Lights off (Wall switch off) - All lights on.

The present invention aims to resolve this contradiction.

an illumination lamp that changes, an operating member such as a pull string or a push button, and a first switching means for switching the illumination state to the N stages in a predetermined order by operating the operating member;
and second switching means for switching the illumination state from the predetermined order to N-1 stages excluding turning off in conjunction with opening and closing of the power supply circuit of the illumination lamp.

[Effect]

When a pull string or the like provided on the lighting device is operated, the first switching means is activated, and the lighting state is switched into N stages including lights out, such as, for example, all lighting - dimming lighting, one algorithm lighting, one lighting, lights out → all lighting. Change. Therefore, it is also possible to turn off the light by operating a pull string or the like.

On the other hand, when the power supply circuit is opened or closed by operating a wall switch, etc., the second switching means is activated, and the lighting status is switched to N-1 stages excluding lights out, such as all on - dimmer on, one algorithm on, all on. Change. Therefore, when switching from arithmetic lighting to full lighting using an ordinary wall switch, a simple operation of turning on the algorithm - turning off the light (turning off the wall switch) - turning on the full lighting is sufficient.

〔Example〕

From the point of view of industrially utilizing the present invention, the first switching means and the second switching means are designed to share many parts in terms of structure, thereby reducing the size, weight, and cost of the device of the present invention. It is preferable. One such embodiment will now be described with reference to the drawings. The drawing shows the circuit configuration of a lighting device according to an embodiment of the present invention and the connection of a power supply circuit 2 that connects the lighting device and a power source 1.

The lighting lamp 3 consists of a dimmable fluorescent lamp 4 and a method 5. In the first step of the switching operation, which will be described later, the switch 6 closes and all of the fluorescent lamps 4 are turned on, and in the second step, switches 6 and 7 are closed. Then, the fluorescent lamps 4 are dimmed and turned on, and in the third stage, the switch 8 is closed and the lamp 5 is turned on, and in the fourth stage, all the switches are opened and the lights are turned off.

The second switching means for switching the illumination state of the illumination lamp 3 into three stages in the above-mentioned order excluding the fourth stage of extinguishing in conjunction with the opening and closing of the power supply circuit 2 will be explained first. In the following description, the power supply circuit 2 is opened and closed using the wall switch 9, but it can also be opened and closed by plugging and unplugging the power outlet.

When the wall switch 9 is turned on, the capacitor 12 is immediately charged via the step-down resistor 10 and the diode 11, and this voltage is applied to the D-type flip-flop ICl3.
become.

When the voltage of the capacitor 12 reaches the Zener voltage of 12V of the Zener diode 14 during this charging, the transistor 16 becomes conductive due to the base current passing through the resistor 15 and the Zener diode, and at the same time the voltage of the capacitor 12 is applied to the resistor 17. , CP as a clock pulse,,! :
CP. The voltage of the capacitor 12 is stabilized at the Zener voltage of 15 V of the Zener diode 18.

When wall switch 9 is first turned on, capacitors 19 and 20
Since D1 and D2 are uncharged, both D1 and D2 are at low levels. Therefore, by the clock pulse, ICl3
Q, Q2 output becomes low level, and Q□ and Q2 output become high level.

The switch 6 is controlled to close by the Q1 output at a high level, but the switch 6 is closed even though the Q2 output is at a high level.

The outputs of R circuits 21 and 22 are both off, and switch 7
and 8 are not controlled to close. Therefore, the fluorescent lamp 4 becomes the first stage of full lighting.

The switch 6.7.8 is composed of a semiconductor such as Cyrisk or a relay, but since the technology of controlling a semiconductor or relay with the output of an IC or logic circuit is well known, illustration and description thereof will be omitted.

In the first stage, the Q0 output is at a high level, so the capacitor 20 is charged through the resistor 23, and the D2 power is at a high level, and the Q2 output is at a low level, so the capacitor 19 is not charged, and the D1 power is at a low level. . Therefore, when a clock pulse is applied, the Q1 and Q2 outputs are at high level 2.
Switch to stage.

Clock pulses are applied by opening and closing wall switches 9. That is, when the wall switch 9 is turned off, the capacitor 12 charged to 15V is discharged by the resistors 15 and 17, and the voltage of 1
When the voltage drops to 2V, the transistor 16 becomes non-conductive,
The voltage applied to resistor 17, CP□, and 022 human power disappears. Therefore, when the wall switch 9 is turned on again, the transistor 16 becomes conductive due to the charging of the capacitor 12.
A clock pulse is generated.

In the second stage, the Q□ ratio output is at a high level, so switch 6 is
is closed, and at the same time, since the Q0 output and the 102 output are at a low level, the switch 7 is closed by the output of the NOR circuit 21, and the fluorescent lamp 4 is dimmed and lit. However, since the Q1 output is at a high level, the output of the NOR circuit 22 is off, and Arithmetic 5 does not light up.

In the second stage, both Ql and Q2 outputs are at high levels, so when capacitors 19 and 20 are charged, Dl and D2 outputs are both at high levels. Therefore, by applying a clock pulse, Ql
and the Q2 output switches to the third stage at a high level. In the third stage, the Q1 output is at a low level, and since the 01 output is at a high level and the output of the NOR circuit 21 is off, the switch 6
．． 7 or open together. However, since both the Ql and Q2 outputs are at a low level and the output of the NOR circuit 22 is on, the switch 8 is closed and the logic 5 is lit.

In this third stage, the Q□ ratio output is at a low level, so the VDI
) from resistor 25, Ql, Vss to capacitor 12
A discharge circuit is formed, and its time constant is, for example, 0.3.
It is set to seconds. Therefore, as soon as the wall switch 9 is turned off, a discharge occurs and the circuit returns to the state before the wall switch 9 was first turned on. Therefore, when the wall switch 9 is turned on next time, the process returns to the first stage.

Next, a first switching means for switching the illumination state of the illumination lamp 3 to four stages, from the first stage to the fourth stage, including extinguishing, by operating the pull string 26 will be explained.

When the pull string 26 is pulled, a switch 27 connected to the base circuit of the transistor 16 opens, turning off the transistor 16 and eliminating the voltage applied to the resistor 17 and CP1 and 022.

When the pull string 26 is released, the switch 27 closes, turning on the transistor 16 and applying the voltage of the capacitor 12 to the resistor 17, simultaneously clocking CPl and CP2.
Applied to human power. Therefore, it is unnecessary to explain that the first stage - second stage = third stage can be switched by operating the pull string 26.

However, if the power supply circuit 2 is opened or closed in the third stage, the light returns to the first stage as described above, but if the pull string 26 is operated in the third stage, the light is switched off in the fourth stage.

In other words, in the third stage, a discharging circuit passing through the resistor 25 is formed as described above, but since the charging current through the resistor 10 is much larger than the discharging current through the resistor 25, the charging current through the resistor 25 is much larger, so unless the charging circuit 2 is opened. The discharge circuit is inactive.

In the third stage, since Q2 output is high level, capacitor 19
When charging, the D1 power is at a high level and the Q1 output is at a low level, so the capacitor 20 is not charged and the D2 power is at a low level. Therefore, when a clock pulse is applied by operating the pull string 26, the Ql and Q2 outputs are switched to the fourth stage at a high level. In the fourth stage, the Q□ ratio output is at a low level, and the Q2 output is at a high level and the NOR circuit 21 is activated.
Since the outputs of and 22 are both off, all the switches 6, 7, and 8 are closed and the lighting lamp 3 is turned off.

In the fourth stage, both the Q2 and Q1 outputs are at a low level, so capacitors 19 and 20 are not charged, and both D□ and D2 output are at a low level. Therefore, when a clock pulse is applied, the first stage is also selected.

In the illustrated embodiment, when the wall switch 9 is turned off, the discharge of the capacitor 12 stops at the Zener voltage of 12 V of the Zener diode 14, except in the case of the third stage. Therefore, even if the wall switch 9 is turned off for a long time, it will be switched in the predetermined order. However, if a resistor is connected in parallel to the capacitor 12 and the time constant of discharge by the resistor is set to 1 second or several seconds, after the wall switch 9 has been turned off for a certain period of time, the process will proceed to the first stage regardless of the above-mentioned predetermined order. Return.

In the illustrated embodiment, the illumination light 3 is switched in four stages, including turning off, but it may also be switched in three stages, for example, fluorescent light on, arithmetic lighting, and off, or it can be switched in five or more stages using multi-stage dimming, etc. It may be switched.

Depending on the purpose and structure of the lighting device, a push button is more suitable as an operating member than a pull string, so the switch 27 may be opened and closed by a push button. Further, a well-known touch sensor, infrared sensor, ultrasonic sensor, etc. can be used as the operating member, and switching can be performed by touching or approaching the operating member with the hand. Furthermore, in the same way as remote control of a television or the like, it is also easy to switch the ceiling lights using an operating member placed at the bedside, for example.

〔Effect of the invention〕

A feature of the lighting device of the present invention is that when switching the lighting state using an operating member such as a pull string included in the lighting device, it is possible to switch the lighting state in a predetermined order including turning off, such as all lights on - dimmed lights → arithmetic lights - lights off - all lights on. When switching is performed using a power supply circuit opening/closing means such as a wall switch, the switching is performed in a predetermined order, excluding lights off, such as all lights on → dimmer lights → all lights on → all lights on.

Therefore, it is possible to turn off the light by operating a pull string or the like, and at the same time, switching from arithmetic lighting to full lighting in the above example can be achieved with a single opening/closing operation of the power supply circuit, which is a very convenient effect. Furthermore, since the light can be turned off using a pull string or the like, the lighting device of the present invention can be used without any problem even in places where there is no power circuit switching means such as a wall switch.
