DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device and a lighting fixture capable of changing light output.

[0002]

2. Description of the Related Art Conventionally, a remote control device having a push button switch as an operation unit has been used, and the light output of a light source is stepwise changed by a pressing operation of the push button switch with a change width such that a person can perceive the change of the light output. There is provided an illumination device capable of performing a step dimming mode.

On the other hand, in some cases, it is required to finely adjust the light output of the light source. In order to cope with such a demand, it is conceivable to reduce the change width of one step in the step dimming mode. I have. In other words, if the light output between the unlit state and the rated lighting is divided into multiple steps, for example, if the change width in one step is set to such a degree that a human cannot perceive, the light output of the light source changes continuously. Will be perceived as such. However, in general, in the step dimming mode, the light output is set to be changed by one step every time the push button switch is pressed, and the multi-step dimming mode in which the change width of one step is small is performed. For example, the number of times the push button switch is pressed to obtain a desired light output increases, which causes a problem that the operation is troublesome.

Therefore, a multi-step continuous dimming level having a relatively small change width is set, and the light output is increased by one step of the continuous dimming level for a predetermined time during a period in which the push button switch is continuously depressed. A continuous dimming mode in which the distance is changed at intervals, and a light having a comparatively large variation width for each pressing operation of the push-button switch, and one step of the step dimming level set with a smaller number of steps than the continuous dimming level. There has been proposed an illumination device that enables both a step dimming mode in which an output is changed. That is, in the continuous dimming mode, the light output of the light source increases or decreases with the passage of time during the pressing operation of the push button switch.

[0005] Recently, there has been provided a device in which both a continuous light control mode and a step light control mode can be selected by one remote control device. In a lighting device using this type of remote control device, a push button switch is provided. In order to reduce the number of
Some devices have a configuration in which a stepwise dimming mode or a continuous dimming mode is selected according to the length of time for which a push button switch is pressed. That is, in the step dimming mode, the step dimming level is changed by one step by one pressing operation. Therefore, when the operation time of the push button switch is short as shown in FIG. 4B, the step dimming mode is selected. When the operation time of the push-button switch becomes relatively long as shown in FIG. 3A, the continuous light control mode is selected (in the illustrated example, the push-button switch is pressed at the settable minimum light output level, and the maximum light output is set). This indicates that the push operation is continued until the output level is reached.)

[0006]

By the way, with the above configuration, the continuous dimming level is 1 in the continuous dimming mode.
It is necessary to judge between the step dimming mode and the continuous dimming mode within the step-changing time interval. In order to make the light output appear to change smoothly in the continuous dimming mode, the continuous dimming level must be determined. Since the change width of one step is reduced and the time interval per one step is also shortened, in order to distinguish the selection operation of the step dimming mode from the selection operation of the continuous dimming mode, the pressing operation of the push button switch is performed. There is no room in the selection range of the threshold set as the time from the start to the end.
That is, this threshold must be set to a small value,
The continuous dimming mode is selected only by slightly increasing the time for pressing the push button switch.

On the other hand, since there is an individual difference in the time for pressing the push button switch to select the step dimming mode, the threshold value for discriminating between the step dimming mode and the continuous dimming mode is small as described above. When the value is a value, the possibility that the continuous light control mode is selected in order to select the step light control mode increases.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to use a single operation unit for the operation of the step dimming mode and the continuous dimming mode, but also to switch the step dimming mode to the continuous dimming mode. It is an object of the present invention to provide a lighting device and a lighting fixture that can easily select a dimming mode without error.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following embodiment, as shown in FIG. 1, an example of a lighting device having a lighting device 1 and a remote control device 2 as an operation unit will be described. Lighting equipment 1
Includes a light source 10, to which power from an AC power supply AC which is a commercial power supply is supplied via a lighting circuit 11.
As the light source 10, for example, a so-called double annular fluorescent lamp in which the internal spaces of two annular tubes having different diameters communicate with each other to form one discharge path is used. However, the technical idea of the present invention can be applied to any shape of the light source 10.

The lighting circuit 11 generates a DC voltage from, for example, an AC power supply AC, converts the DC voltage into a high frequency alternating voltage by an inverter circuit, and supplies the high frequency alternating voltage to the light source 10. In this type of lighting circuit 11, the power supplied to the light source 10 can be adjusted by changing the on / off frequency of the switching element forming the inverter circuit. That is, the lighting circuit 11 is provided with a driving circuit 11a for driving the switching element, and the driving circuit 11a receives a dimming control signal, which is a voltage signal, from the outside and outputs a driving signal having a frequency corresponding to the voltage value. The optical output of the light source 10 is controlled by including a drive signal to the switching element. Further, the lighting fixture 1 is provided with a bead as an auxiliary light source 13 in addition to the light source 10 described above. The light output of the auxiliary light source 13 is controlled by a lighting circuit 14 provided separately from the lighting circuit 11.

The dimming control signal given to the driving circuit 11a is
It is generated in the dimming control circuit 12. Dimming control circuit 1
2 is light transmitted from the remote control device 2 (generally infrared light)
Receiving unit 1 for receiving a wireless signal through a medium
2a. The dimming control circuit 12 controls not only the lighting circuit 11 but also the lighting circuit 14.

On the other hand, the illustrated remote control device 2 has a flat container 20 large enough to be held by one hand. On the front surface of the housing 20, a lighting switch 21 and a light-off switch 2 for instructing the light source 10 to turn on and off, respectively.
2 and a bead ball switch 23 for instructing lighting of the auxiliary light source 13
And a dimming switch 24 for instructing dimming lighting to reduce the light output of the light source 10 from the rated lighting state, and instructing adjustment of the light output of the light source 10 in a state where dimming lighting is instructed by the dimming switch 24. An up switch 25 and a down switch 26 are provided. These switches 21 to 26 are
Each is a push button switch and generates an operation signal during a push operation. The operation signals of the switches 21 to 26 are transmitted to the dimming control circuit 12 by wireless signals.

The up switch 25 is basically connected to the light source 10.
Or, an instruction to increase the light output of the auxiliary light source 13 is given,
The down switch 26 basically gives an instruction to decrease the light output of the light source 10 or the auxiliary light source 13. The auxiliary light source 13 may be turned on and off without performing light control. The light output that can be set by the up switch 25 and the down switch 26 is 0%
And the rated lighting is set to 100% and set in multiple stages. As described in the conventional configuration, there are basically two types of light output level instruction modes by the up switch 25 and the down switch 26.
5 or a continuous dimming mode in which the light output level is changed over time with a relatively small change width when the pressing operation of the down switch 26 is continued, and the pressing operation of the up switch 25 or the down switch 26 is performed in a short time. In this case, a step dimming mode in which the light output level is changed by one step of the step dimming level, which is a relatively large change width, can be selected. However, it goes without saying that the light output level can be adjusted only between the upper limit value and the lower limit value of the setting range of the light output level regardless of the continuous light control mode or the step light control mode.

The configuration of the lighting apparatus 1 described above is an example for describing the following embodiment, and other configurations can be adopted as long as the configuration of the light source 10 can be adjusted. . In addition, a configuration example in which the remote control device 2 is used as an operation unit and the light output of the light source 10 is made variable by giving an instruction to the lighting apparatus 1 using a wireless signal by light from the remote control device 2 is shown. The technical idea of the present invention can be applied to a configuration in which an operation unit is connected to the control circuit 12 by wire, and any route may be used to give an instruction from the operation unit to the dimming control circuit 12.

In the following embodiment, the operation of the dimming control circuit 12 when the up switch 25 or the down switch 26 is operated, which is the gist of the present invention, will be described.
However, when the down switch 26 is operated,
Since the change direction of the light output level is different from the operation when the up switch 25 is operated, only the up switch 25 will be described unless otherwise necessary, and the change direction of the light output level will be described for the down switch 26. Should be read as the reverse.

(First Embodiment) In the dimming control circuit 12 of the present embodiment, as shown in FIG. 1B, when the up switch 25 is pressed at time t1 and an operation signal is generated, first, the step adjustment is performed. The light output is increased by a level corresponding to one step of the light level, and thereafter, during a prescribed standby period T1, the light output is kept constant regardless of whether the up switch 25 or the down switch 26 is pressed or not. It is. At time t2 when the standby period T1 ends, the pressing operation of the up switch 25 has been completed,
If the up switch 25 is not operated during the waiting period T1, the above-described light output is maintained. That is, in this operation, the step light control mode is selected. On the other hand, if the pressing operation of the up switch 25 is continued at the end of the standby period T1, the device operates in the continuous dimming mode while the pressing operation of the up switch 25 is continued from the end of the standby period T1. .

Here, the dimming control circuit 12 has 0 to 10
The continuous dimming level in which the continuous dimming level of 0% (rated lighting) is set in 101 steps in 1% increments and the step dimming level in which the 0-100% step dimming level is set in 21 steps of 5% each Is set. In the continuous dimming mode, the continuous dimming level changes the light output level by one step at a fixed time interval with time, and in the step dimming mode, the light output level changes by one step of the step dimming level I do. Further, the five steps of the continuous dimming mode correspond to one step of the step dimming level, and the time required for the continuous dimming level to increase by five steps in the continuous dimming mode is the time corresponding to the standby period T1. It is set to be. The standby period T1 is set to be larger than the maximum value of the variation range in consideration of the variation in time when a person presses the up switch 25 for a short time. Therefore, the up switch 25
By pressing, the light output increases by a level corresponding to one step of the step dimming level regardless of the length of the operation time.

At the end of the waiting period T1, it is determined whether or not the pressing operation of the up switch 25 is continued. If the pressing operation of the up switch 25 is not continued at the end of the standby period T1, the up switch 25 is pressed for a short time, and after the standby period T1, the same step light control as the standby period T1 is performed. The light output at the level is maintained.
On the other hand, if the pressing operation of the up switch 25 is continued at the end of the standby period T1, the operation in the continuous dimming mode is selected during the period in which the pressing operation is continued.

In short, similarly to the conventional configuration, the continuous dimming mode is selected if the pressing operation of the up switch 25 continues for more than the specified time, and the stepwise dimming mode is selected if the pressing operation is shorter than the specified time. Will be. However, in the conventional configuration, the step dimming mode is selected for a pressing operation of a time shorter than the time corresponding to one step of the continuous dimming mode, and the pressing operation exceeding the time corresponding to one step of the continuous dimming mode is performed. While the continuous dimming mode has been selected for the operation, in the present embodiment, the step dimming mode and the continuous dimming mode are determined based on a time corresponding to a plurality of steps of the continuous dimming mode. As a result, there is ample time to determine the step dimming mode and the continuous dimming mode, and the possibility of erroneous determination is greatly reduced. In other words, a relatively large variation in the pressing operation time of the up switch 25 when selecting the step dimming mode is allowed, so that the step dimming mode and the continuous dimming mode can be easily distinguished.

In the configuration of the present embodiment, at the time when the pressing operation of the up switch 25 after the continuous dimming mode is selected, the continuous dimming level does not always match the step dimming level. When the up switch 25 or the down switch 26 is depressed, the continuous dimming mode 5 corresponding to one step of the step dimming level is performed.
The light output is changed by the amount of the step. For example,
If the step dimming level is set in increments of 5% as described above, if the up switch 25 is pressed while the light output is 0% (off), the light will be emitted immediately after the up switch 25 is pressed. The power level increases up to 5%. On the other hand, if the light output level at the end of the continuous dimming mode (at the end of the pressing operation of the up switch 25) is 17%,
Next, immediately after operating the up switch 25, the light output level becomes 22%. In other words, the step dimming level of 20%
Or 25%.

(Second Embodiment) In the first embodiment, the light output level at the end of the continuous dimming mode is not particularly limited. However, in the present embodiment, the continuous dimming is not performed. The light output level at the end of the light mode is regulated to match the step light control level.

That is, as shown in FIG. 2, the continuous dimming mode is continuously selected for a time period during which the pressing operation of the up switch 25 exceeds the standby period T1, and when the pressing operation of the up switch 25 ends at time t3, Switch 25
Is not the continuous dimming level X at the end of the pressing operation, but is the level higher than the continuous dimming level X and the closest step dimming level L (n) (n = 0, 1, 2,...) , 2
1) is selected. In short, L (n-1) <X ≦ L
In the case of (n), L (n) is selected as the light output level after the operation of the up switch 25 is completed.
As described above, when the continuous dimming mode is selected, an arbitrary continuous dimming level is not set, and the light output is always set to match any one of the step dimming levels Ln. It is.

For example, if the up switch 25 is pressed while the light output level is 20%, the light output level rises to 25% immediately after the pressing operation, and then the standby period T
If the pressing operation of the up switch 25 is continued beyond 1, the mode shifts to the continuous light control mode. If the pressing operation of the up switch 25 is terminated when the light output level becomes 77% after the shift to the continuous dimming mode, the step dimming level higher than 77% and closest is 80%. The light output level after the end of the pressing operation of the switch 25 becomes 80%. Here, even after the pressing operation of the up switch 25 is completed,
By reaching the light output level of 80% in the same manner as when the up switch 25 is operated, it is possible to reach the step dimming level without causing a sense of incongruity. However, in this case, a time delay occurs from the end of the operation of the up switch 25 to the time when the light output level becomes constant. There is no discomfort. When the continuous dimming mode is selected by the down switch 26, at the end of the pressing operation, a step dimming level lower and closest to the light output level at that time may be selected. Other configurations and operations are the same as those of the first embodiment.

As described above, in the configuration of the present embodiment, even if the continuous dimming mode is selected and the optical output level is changed, the settable optical output level matches the step dimming level. The step dimming mode and the continuous dimming mode differ only in the operation, and the light output levels that can be set are the same. That is, when setting a desired light output level, the same light output can be easily set by any of the operation methods of the step light control mode and the continuous light control mode.

(Third Embodiment) In the present embodiment, an operation mode is determined according to whether the up switch 25 is pressed or pressed within a specified period before the up switch 25 is pressed. Can be selected. That is, as shown in FIG. 3, when the up switch 25 is pressed again in the standby period (specified period) T1 after the up switch 25 is pressed, and in the selection period T2 after the up switch 25 is pressed. Up switch 2 at
The operation mode is switched between when the user presses the button 5. Here, in the present embodiment, the standby period T1
And the selection period T2 have the same length.

First, the up switch 25 is pressed at time t1, and thereafter, at time t2 when the waiting period T1 ends.
The operation in the case where the up switch 25 is pressed again at time t5 before and the second push operation of the up switch 25 continues beyond the end of the standby period T1 will be described. For the first pressing operation of the up switch 25, similarly to the first embodiment, immediately after the pressing operation, the light output level is increased by one step of the step dimming level, and during the standby period T1, Maintain the light output level after the rise. Here, at time t5, the up switch 25 is pressed, and the switch is continuously pressed even after the end of the standby period T1, so that the mode shifts to the continuous light control mode. That is, during the period in which the pressing operation of the up switch 25 is continued, the light output level increases by one continuous dimming level. However, in this case, after the pressing operation of the up switch 25 is finished, the light output level at the end of the pressing operation of the up switch 25 is maintained.
Further, in order to make it easier to select the light output level of each stage, the maintenance time (time interval) T3 until the light output level changes to the next stage is set relatively long. That is, the change speed of the light output level in the continuous dimming mode is relatively slow. Therefore, the pressing operation of the up switch 25 ends at time t3, and thereafter, the up switch 25
Is not performed, the light output of the light source 10 is maintained at the light output corresponding to the light output level Kn shown in FIG.

On the other hand, at time t3, the up switch 2
At time t6 before the selection period T2 after the end of the pressing operation of No. 5 ends at time t4, the up switch 25 is pressed again, and the pressing operation of the up switch 25 continues beyond the end of the selection period T2. The second
The continuous dimming mode having the same form as that of the embodiment is selected. That is, at the end of the pressing operation of the up switch 25, the light output level at the end of the pressing operation is not set, but rises to the nearest step dimming level higher than the light output level at the end of the pressing operation. Then, the step dimming level is selected as the light output level. Since the continuous dimming level is not selected in this operation mode, the change speed of the light output level is faster than in the above-described operation mode when the up switch 25 is pressed twice. Here, in the above example, even when the down switch 26 is pressed instead of the up switch 25 during the selection period T2, the operation mode in which the continuous dimming mode in which the change speed is relatively fast is selected. In this case, the light output level changes in a direction to decrease. In addition, when the up switch 25 is pressed once to shift to the continuous light control mode, the pressing operation of the up switch 25 is once ended, and the up switch 25 or the down switch 26 is pressed again in the selection period T1. Also, the operation mode in which the continuous dimming mode having a relatively fast changing speed is selected. Further, when the up switch 25 is pressed and the up switch 25 is continuously pressed until the end of the standby period T1 is exceeded, the mode shifts to the continuous dimming mode as in the second embodiment. At the end of the pressing operation of the up switch 25, an operation is performed in which a step dimming level close to the light output level at that time is selected.

In the configuration of the present embodiment, the light source 10 has a light output corresponding to the step dimming level in both the continuous dimming mode and the step dimming mode, as in the second embodiment.
In addition to the operation mode of turning on the light source, the operation mode of turning on the light source 10 with the light output corresponding to the continuous dimming level of each stage is also selectable.
The light output level can be roughly set or finely adjusted. Moreover, since the operation mode is selected by the procedure of pressing one up switch 25, the number of the push button switches in the remote controller 2 does not increase.

In each of the above-described embodiments, 101 levels are set assuming that one level of the continuous dimming mode is 1% and 21 levels are set as one level of the step dimming level is 5%. Is an example, and the number of steps and the width of change in one step can be appropriately selected in both the continuous light control mode and the step light control mode, and the change width in one step does not need to be constant. . Further, although a push button switch is used for the up switch 25 and the down switch 26 which are the operation units, a switch of a configuration other than the push button switch has a type in which on / off is reversed between when operated and when not operated. As long as the switch is a switch having another configuration, it can be used for the operation unit.
