Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention controls lighting of a light source based on a remote control signal formed by infrared rays, visible light, radio waves, sound waves, etc. Regarding lighting devices.

(Prior art) Conventionally, as this type of device, for example,
No. 99 has been proposed. This device remotely controls the turning on and off of a light based on a blinking control signal from a transmitter of a remote control device. Although this device only controls the lighting and turning off of electric lights, there has also been proposed a device that sends a dimming control signal to control the light source at a fixed dimming level set in advance. ing.

In addition, for example, as in Japanese Patent Publication No. 60-54758, the lighting state of the light source is changed in order such as full lighting - dimming lighting - baby bulb lighting - lights out depending on the time when the operating part is operated, In addition, there have also been proposed devices in which the dimming lighting can be switched in degrees.

(Problems to be Solved by the Invention) However, the above-mentioned Utility Model Application Publication No. 60-74499 can only control the light source to turn on and off, and even if it is possible to select the dimming lighting, Since the light can only be dimmed at a fixed dimming level, it cannot meet the need to vary the lighting in a variety of ways. It is also conceivable to set a plurality of fixed dimming degrees and provide a plurality of dimming command operation sections corresponding to the plurality of types of dimming degrees in the transmitting section, but in this case, the transmitting section In the dimming command operation unit, for example, the number of push buttons equal to the number of dimming levels is required, making implementation difficult and increasing the size of the transmitting unit. Furthermore, from the operator's perspective, selection of the operating section is troublesome, and there is a risk that the operator may operate it incorrectly. Furthermore, it is necessary to separately allocate control signals corresponding to each operation section to the transmitting section and the receiving section, which inevitably increases complexity and cost. Furthermore, the thing in the above-mentioned Japanese Patent Publication No. 60-54758 is
In order to achieve the desired lighting state i14, it may be necessary to operate the operating section for a long time until the desired turn is reached, which poses a problem in that the operation is cumbersome.

The present invention was made to solve these problems, and can meet the needs of various light outputs.Moreover, it minimizes the number of dimming command operation parts, reduces the size of the transmitter,
It is an object of the present invention to provide a lighting device that can simplify operations to obtain a desired lighting state, prevent erroneous operations, and reduce the price.

[Structure of the Invention] The present invention has at least a lighting command operation section, a lights out command operation section, a light output increase command operation section, and a light output decrease command operation section, and by operating these command operation sections, infrared and visible light can be transmitted. ,
a transmitting section that sends out a remote control signal formed by radio waves, sound waves, etc.; a receiving section that receives the control signal; and a control signal received by the receiving section that is a control signal from the lighting command operation section. When the control signal is from the light-off command operation section, the light source is turned on, and when the control signal is from the rise command operation section or the descent command operation section, the light source is dimmed and turned on. and a lighting control device, the lighting control device having a storage means for storing the lighting control state of the light source according to the previous control signal, and the lighting state stored in the storage means is a lighting state or a dimming lighting state. The light output of the light source is increased or decreased based on the stored lighting control state only when a control signal is received by operating the ascending command operating section or the descending command operating section at a certain time. It has the above characteristics.

(Function) In the present invention, a lighting control signal or a lights-off control signal is sent from the transmitter by operating the lighting command operating section or the lights-off command operating section. These control signals are received by the receiving section, and the lighting control device turns on or off the light source based on these control signals.

Further, the lighting control device stores the lighting control state of this light source.

Further, when the ascending command operating section or the descending command operating section of the transmitter is operated, an ascending control signal or a descending control signal is sent. The receiver similarly receives such control signals, but the lighting control device checks the current lighting control state (before receiving the ascending control signal or descending control signal) and determines whether it is full lighting or dimming lighting control. Only when the light source is in this state, the light source is dimmed and turned on in response to the rise control signal or the fall control signal. This allows the light output of the light source to be increased or decreased to a desired value. For example, if the light output of the light source is 60%, 70%, 80%, 90%, 100% and IO%
It is set to be dimmable at intervals, and all lights are on, i.e. 10
Assuming that the light is lit at 0%, it can be changed to 90% dimming by operating the lowering command operation section, 80% dimming by further operating, and so on, up to 60% dimming.

The opposite is true when increasing. Also, for example, 80
It goes without saying that both raising and lowering can be commanded arbitrarily during % dimming. Note that when the current lighting control state is off, the rise control signal or the fall control signal is ignored.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 6. Reference numeral 1 denotes a transmitting section, which in this embodiment transmits a control signal using infrared rays as a medium by operating each operating section to be described later. In the present invention, the operation section includes at least a lighting command operation section 2 for lighting at a preset maximum light output, a lights-off command operation section 3, a rise command operation section 4, and a lowering command operation section 5. However, in this embodiment, a dimming lighting command operating section 6 and a night light lighting command operating section 7 are further provided.
It also has the following.

Reference numeral 8 denotes a lighting device, for example, a hanging type lighting device, which has a light source 9 such as a fluorescent lamp, and has a receiving section 10 and a lighting control device 11 housed in the device main body 8a.

Note that one or both of the receiving section 10 and the lighting control device 11 may be arranged separately from the lighting fixture 8. The receiving section 10 receives a control signal from the transmitting section 1, and the lighting control device 11 controls lighting of the light source 9 based on the control signal received by the receiving section 10. . The lighting control device 11 includes a signal processing section 12, a variable output lighting device 13 that controls the power supplied to the light source 9 according to the output from the signal processing section 12, and stores the lighting control state of the light source 9. It has a storage means 14 for storing information. Although the signal processing section 12 and the storage means 14 are shown as separate bodies, they are generally constructed integrally using a microcomputer or the like. This lighting control device 11 will be described in more detail. That is, the lighting device 13 is mainly composed of, for example, an inverter, and its output can be changed by controlling the oscillation frequency and the like. However, other means may be used as the output changing means, and the lighting device itself may be of a conventional iron type. Further, the signal processing section 12 and the storage means 14 of the lighting control device 11 are configured to perform the functions shown in FIGS. 2 and 3. As shown in FIG. 2, the basic operation is that when the power is turned on, the device is started, initialized, and becomes ready for control signals. When a control signal is received, the content is determined and based on the determination result, lighting control, raising/lowering control, dimming control, night light lighting control, and light extinguishing control are performed. Then, this lighting control state is stored in the storage means 14, and the control signal standby state returns. Next, we will discuss the process when a rise or fall control signal is received. As shown in FIG. 3, it is first determined whether it is a rise control signal or a fall control signal. Here, to explain the case where it is a rise control signal, first, it is determined whether or not the previous lighting control state stored in the storage means is a dimming lighting state, and if it is a dimming lighting state. Determine whether it is limited to 1 or not. In the above, when the dimming lighting state is not reached, the standby mode returns to the standby state without proceeding to the next step. Further, when the dimming lighting state is limited to "1", that is, 100% lighting in this embodiment, the standby mode returns to the standby state without proceeding to the next step. If it is not the upper limit, a confirmation sound is generated using the buzzer 15, etc., and the light output is reduced to one level (10% in this example).
A signal to raise the level is output to the lighting device 13, and the standby state returns. The lighting device 13 changes its output according to the signal from the processing device 12 to increase the light output of the light source by 10%.

When receiving the lowering control signal, the control is performed in the opposite manner, but since it is easily understood from FIG. 3, the explanation will be omitted. In this embodiment, the confirmation sound by the buzzer 15 or the like is generated only when the dimmed lighting state changes. In other words, even if a rise or fall control signal is received when the optical output is at the upper or lower limit,
The optical output is not controlled and the confirmation sound is not generated. However, the present invention may be configured such that when the upper limit is reached, the optical output is controlled again from the lower limit toward the upper limit. Even when reducing the optical output, when the lower limit is reached, the optical output may be controlled again from the upper limit toward the lower limit. Note that 16 is a night light.

Next, the operation of this embodiment will be explained. By operating each command operating section 2 to 7 of the transmitting section 1, a corresponding control signal is sent out. The receiving unit 10 receives this control signal and transmits it to the lighting control device 11.

The lighting control device 11 first determines which lighting control the control signal instructs, as shown in FIG. 2, and controls the lighting according to the content of the instruction. As mentioned above, when it is a raise/lower control command, it acts as shown in FIG. 3. This lighting control state is stored in the storage means, and the next control signal is read out at some time. FIG. 6 shows such changes in the lighting state. In addition,
In FIG. 6, "all" indicates a lighting control signal, "off" indicates a light-off control signal, rUJ indicates a rising command signal, and rDJ indicates a descending command signal. Furthermore, since a confirmation sound is generated when the lighting state of the light source 9 changes in accordance with the control signal, the operator can confirm that the control signal has been reliably transmitted and that the lighting state has been changed.

Although FIG. 7 shows another embodiment, it only shows the processing procedure of the lighting control device, and since the rest is the same as that of the above embodiment, illustration and explanation will be omitted. In this embodiment, as is clear from FIG. 7, the confirmation sound is generated the first time even if the optical output is at the upper or lower limit.

Note that in the present invention, the remote control signal may be transmitted via a signal line. Further, the lighting equipment may be provided with an operating section such as a pull switch, and the lighting of the light source may also be controlled by this operating section. Even in this case, since the lighting control device remembers the previous lighting control state, it is possible to change the light output by operating the ascending command operating section or descending command operating section when in the lighting state or dimmed lighting state. It is.

[Effects of the Invention] As described above, the present invention has at least a lighting command operating section, a lights out command operating section, a rising command operating section that increases the light output, and a descending command operating section that similarly decreases the light output, and these command operating sections a transmitter that transmits a remote control signal by operating the
A receiving unit that receives the control signal; and a lighting control device that controls turning on, turning off, and dimming the light source based on the control signal received by the receiving unit, and the lighting control device has a previous control. A storage means for storing a lighting control state of the light source according to the signal is provided, and when the lighting control state stored in the storage means is a lighting state or a dimming lighting state, the rise command operation section or the descent command operation section is operated. When a control signal is received, the stored lighting state is read out and the light output is increased or decreased based on this, so that various light outputs are controlled mainly from the rise command operation section and the descent command operation section. It can be easily obtained as In addition, while it is possible to obtain such a variety of optical outputs, only two command operation units are required, which is advantageous in terms of implementation and allows miniaturization. Further, the risk of erroneous operation due to an increase in the number of operation sections does not increase. Furthermore, fewer operation units means fewer types of corresponding control signals, which simplifies the configuration of the transmitting unit, receiving unit, and signal processing unit of the lighting device, and provides the product at low cost. becomes possible. Furthermore, the number of operations of the operating section until a desired light output is obtained is smaller than that of conventional devices, so that the operator's annoyance can be reduced.
