BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a dimming controllable lamp which requires a certain time for lighting, and a lamp which can be instantly turned on and dimming controllable simultaneously with lighting. The present invention relates to a lighting device that sometimes fades in or fades out.

[0002]

2. Description of the Related Art Illuminating devices include, for example, a fluorescent lamp which is a dimming-controllable lamp that requires a certain amount of time for lighting, and an incandescent lamp which is a lamp that is instantly lit and can be dimming-controlled simultaneously with lighting. Some are equipped with. An example of this type of lighting device will be described with reference to FIG. This lighting device includes lighting circuits 3 and 4 for individually lighting a fluorescent lamp 1 and an incandescent lamp 2, an operating unit 5 for performing an operation input for controlling lighting of the fluorescent lamp 1 and an incandescent lamp 2, and this operating unit. According to the operation input of 5, the fluorescent lamp 1 and the incandescent lamp 2 are provided in the respective lighting circuits 3 and 4.
And a control circuit 6 for giving a control command for use. The lighting circuits 3 and 4 are capable of continuously controlling the dimming lighting of the fluorescent lamp 1 and the incandescent lamp 2. Further, this lighting device operates by using the commercial power supply AC as a power source.

In this type of lighting device, when the fluorescent lamp 1 and the incandescent lamp 2 are turned on, a certain time (for example, 2.5 seconds)
A so-called fade-out in which the lamp is gradually brightened from the turned-off state to the rated brightness, and when it is turned off again, the lamp is gradually darkened and turned off from the turned-on state for a certain time (for example, 2.5 seconds). I am allowed to do it. The time-illuminance (luminous illuminance) characteristics when the fluorescent lamp 1 and the incandescent lamp 2 are faded in are shown in FIGS. 3 and 4, respectively.

Further, as shown in FIG. 5, the fluorescent lamp 1 and the incandescent lamp 2 may be faded in or out. Note that FIG. 5 shows a case where fade-in is performed.
Here, the characteristic of FIG. 5A is one that is generally called a Munsell curve, and the illuminance change has a characteristic of 2.3 to the time axis, and FIG. a)
It is displayed by taking the logarithm of the luminous illuminance (or luminous flux) of.

Here, in the case of the incandescent lamp 2, the illuminance can be changed with the characteristics shown in FIG. However, when the fluorescent lamp 1 is faded in, as shown in FIG. 6A, the fluorescent lamp 1 is turned on after a preheating period of about 0.6 seconds. When faded out, as shown in FIG.
The lighting state becomes unstable after 2 seconds. In addition,
A region where the lighting is unstable is shown by hatching in FIG.

[0006]

In the illumination device having the fluorescent lamp 1 and the incandescent lamp 2, when the fluorescent lamp 1 and the incandescent lamp 2 are simultaneously turned on, the fluorescent lamp 1 is turned on with a delay of the preheating time. Therefore, the incandescent lamp 2 is turned on first, and then the fluorescent lamp 1 is turned on. Therefore, it is not very pleasant.

When the fluorescent lamp 1 and the incandescent lamp 2 are simultaneously turned on, the incandescent lamp 2 is turned on first, and then the fluorescent lamp 1 is turned on.
When is turned on, the lighting color first starts with the yellow color of the incandescent lamp 2, then suddenly becomes whitish, and then gradually changes to a mixed color. This kind of lighting color change is not very pleasing. The present invention has been made in view of the above points, and an object of the present invention is to provide an illuminating device capable of fading in and fading out comfortably.

[0008]

In order to achieve the above object, the invention of claim 1 is the time when the first lamp is turned on and the time when the fade-in is ended when the first and second lamps are faded in at the same time. And the time before the fade-out start time when the first and second lamps are faded out at the same time as the time required for the first lamp to light up after the second lamp is turned off. The change in the illuminance of the second lamp during the period up to is substantially matched with the change in the illuminance of the first lamp.

In order to make the same change when the first and second lamps are faded in and out at the same time, the first and second lamps are simultaneously faded out as described in claim 1. second lamp off time than the first ramp of Ru turn off the first lamp at a time prior time corresponding to the time required to light up in.

In order to make the operation feeling the same when the first and second lamps are individually faded in or out and when the first and second lamps are simultaneously faded in and faded out, As described in Item 1 , the time required for fade-in and fade-out when the first and second lamps are individually faded in or faded out is
Simultaneously or fade lamp to match the time required for the case of fade-out.

Further, in the state where the first lamp is lit at the minimum illuminance that can be lit, the operation feeling when the illuminance is increased and the first and second lamps are faded in and out at the same time. In order to make the operation feeling the same as when the lighting operation is performed, when an up operation for increasing the illuminance is performed while the first lamp is lit at the minimum illuminance that can be lit, as described in claim 2 , It is preferable to match the time required to reach the maximum or rated illuminance with the time required to simultaneously fade in or fade out the first and second lamps.

The invention of claim 3 achieves the above object.
For, when the first and second lamp lit operated simultaneously
Second from the point until the first lamp lights up
The illuminance of the lamp is changed so that it becomes a straight line on a semi-logarithmic graph, and the change in illuminance becomes visually natural.
As described above, after the first lamp is turned on, the illuminance of the first and second lamps is changed so as to follow the Munsell characteristic curve.
And a straight line that is the change in illuminance of the second lamp during the period from the time when the second lamp is simultaneously turned on to the time when the first lamp is turned on, and the change in illuminance of the second lamp after turning on the first lamp. the curve is, to match the intensity and inclination at the lighting time of the first lamp, it is gradually varied so as to approach the Munsell characteristic curve illuminance change of the second lamp after lighting.

[0013]

According to the first aspect of the present invention, the illuminance changes of the first and second lamps are made to coincide with each other as much as possible, so that the color change of the illumination is prevented as much as possible, and the fade is felt comfortably. In and fade out. In addition, the illuminance change is the same when the first and second lamps are faded out and when the first and second lamps are faded in, and when the first and second lamps are faded in at the same time. Make sure that you don't feel uncomfortable when you do. Further, the operation time is set to be the same when individually performing fade-in or fade-out and at the same time when performing fade-in and fade-out at the same time, and the operation feeling when performing fade-in or fade-out individually and simultaneously is made the same.

According to a second aspect of the present invention, the time when the first lamp is turned on at the minimum illuminance that can be turned on and the maximum or rated illuminance is set by increasing the illuminance is
The same time as when the first and second lamps are faded in or faded out at the same time, and from the state where the first lamp is lit at the lowest illuminance that can be lit, the maximum or rated The operational feeling when the illuminance is set to be the same as the operational feeling when the first and second lamps are simultaneously faded in and faded out.

According to the third aspect of the invention, the first lamp is turned on by changing the illuminance of the second lamp so as to become a straight line on a semi-logarithmic graph during the period until the first lamp is turned on. Until the change in illuminance of the second lamp during the period up to is apparently slow, and when the first and second lamps are turned on at the same time, the feeling that the second lamp is turned on first as less susceptible to feel well is faded in, further by changing the illuminance of the first and second ramp along the Munsell characteristic curve, the change in the illuminance as visually feels natural and, by changing the illuminance of the second lamp, as described above, the effect of less susceptible to feeling white heat lamp is lit above, an effect of visually naturally irradiation of change Both obtained as to.

[0016]

FIG. 1 shows an embodiment of the present invention. The circuit configuration of this embodiment is shown in FIG. 1A, and in the case of this embodiment, FIG. 1B shows the time-illuminance (visual illuminance) characteristics when the incandescent lamp 2 is faded in. It is characterized by the points shown in. The time-illuminance characteristics when the fluorescent lamp 1 is faded in are the same as those in FIG.

Regarding the time-illuminance (luminous illuminance) characteristics when the incandescent lamp 2 is faded in, after the fluorescent lamp 1 and the incandescent lamp 2 are turned on at the same time, the preheating time of the fluorescent lamp 1 elapses ( About 0.6 seconds), the amount of change in illuminance is changed. Specifically, during the preheating period (0 seconds to about 0.6 seconds) until the fluorescent lamp 1 lights up after the preheating time, the illuminance of the fluorescent lamp 1 is finally (at the time of about 0.6 seconds elapsed). Brighten linearly so that it becomes the same as. Then, the illuminance change of the incandescent lamp 2 after the fluorescent lamp 1 is turned on is matched with the illuminance change of the fluorescent lamp 1.

In this way, when looking at the overall illumination color when, for example, the fluorescent lamp 1 and the incandescent lamp 2 are faded in at the same time, the yellow color of the incandescent lamp 1 is initially obtained, When the fluorescent lamp 1 is turned on, the fluorescent lamp 1 and the incandescent lamp 2
Since the colors of and are mixed and the brightness of the fluorescent lamp 1 and that of the incandescent lamp 2 change at the same rate thereafter, the color of the illumination does not change. Therefore, as compared with the conventional one, the fluorescent lamp 1 and the incandescent lamp 2 are naturally arranged.
Can be turned on.

Here, when the fluorescent lamp 1 and the incandescent lamp 2 are faded out, the illuminance is reduced according to the characteristics shown in FIGS. 4 and 1 (b). In this case, the fluorescent lamp 1 is the incandescent lamp 2
Before turning off completely, that is, preheating time (about 0.6 seconds)
The light is turned off before the time corresponding to. By doing so, the illuminance change is the same when the fluorescent lamp 1 and the incandescent lamp 2 are faded out and when the fluorescent lamp 1 and the incandescent lamp 2 are faded in, and the fluorescent lamp 1 and the incandescent lamp 2 are the same.
There is no sense of incongruity between when fade-in is performed and when fade-out is performed.

In the above description, the fluorescent lamp 1 and the incandescent lamp 2 are used.
However, in the case where the fluorescent lamp 1 and the incandescent lamp 2 are individually faded in or faded out, the time required for the fade-in or the fade-out is the fluorescent lamp 1 and the incandescent lamp. It is set to match the time required to fade in or fade out 2 at the same time. By doing so, the operational feeling can be made the same when the fluorescent lamp 1 and the incandescent lamp 2 are faded in or out at the same time and when they are individually faded in or out.

By the way, conventionally, when the fluorescent lamp 1 is lit at the minimum illuminance that can be lit, the time required to reach the maximum or rated illuminance when the up operation for increasing the illuminance is performed is shown in FIG. The time from the lighting time in 3 to the end time of the fade-in operation was set to match. Therefore, when the fluorescent lamp 1 and the incandescent lamp 2 are simultaneously turned on,
There is a problem that the feeling of operation is different.

Therefore, in this embodiment, when the fluorescent lamp 1 is lit at the minimum illuminance that can be lit, the time required to reach the maximum or rated illuminance when the up operation is performed to increase the illuminance is performed. , The time (2.5 seconds) required when the fluorescent lamp 1 and the incandescent lamp 2 are simultaneously faded in is set. In this way, the operation feeling is the same as when the fluorescent lamp 1 and the incandescent lamp 2 are turned on at the same time. Further, when performing an up operation for raising the illuminance of the fluorescent lamp 1 or a down operation for lowering the illuminance, the illuminance change time becomes longer than in the conventional case, so that the desired brightness can be easily set.

That is, according to the present embodiment, the illuminance change is uniformly set to 2.5 seconds regardless of the lighting state and operation of the fluorescent lamp 1 and the incandescent lamp 2. When performing fade-in and fade-out at the same time, when performing fade-in and fade-out individually, and when operating the fluorescent lamp 1 up to the rated or maximum illuminance from the state where the fluorescent lamp 1 is lit at the lowest illuminance that can be lit The operation feeling can be the same.

(Embodiment 2) FIG. 2 shows time-illuminance characteristics when the incandescent lamp 2 of another embodiment of the present invention is faded in. The fluorescent lamp 1 has the characteristics shown in FIG. 6 and is therefore faded in or out. In the present embodiment, as the preheating time (about 0.6 seconds) of the fluorescent lamp 1, the luminous flux of the incandescent lamp 1 is linearly changed on a semi-logarithmic graph as shown in FIG. Change it so that it gradually approaches the Munsell curve. Here, the change in the luminous flux of the incandescent lamp 1 after the preheating time elapses becomes a curve in which the time axis of the Munsell curve is shortened. Then, the straight line and the curved line are in contact with each other at the time of about 0.6 seconds with the light flux and the slope being matched.

As described above, in this embodiment, the illuminance of the incandescent lamp 2 during the period until the fluorescent lamp 1 is turned on is changed so as to become a straight line on the semi-logarithmic graph.
The change in the illuminance of the incandescent lamp 2 during the period until lights up is apparently slow. Therefore, even when the fluorescent lamp 1 and the incandescent lamp 2 are turned on at the same time, it is possible to prevent the incandescent lamp 2 from being turned on first, and the fade-in can be performed comfortably. Further, since the illuminances of the fluorescent lamp 1 and the incandescent lamp 2 are changed along the Munsell characteristic curve, the change in illuminance can be visually perceived naturally.

In each of the above-mentioned embodiments, the illuminating device having both the fluorescent lamp 1 and the incandescent lamp 2 has been described, but a dimming controllable lamp which requires a certain time for lighting and an instantaneous lighting and lighting. At the same time, it goes without saying that the present invention can be applied as long as it is combined with a lamp capable of dimming control.

[0027]

As described above, according to the first aspect of the present invention, when the first and second lamps are faded in at the same time, the period from the lighting time of the first lamp to the end time of the fade-in, the first and second When the fade-out starts when the second lamp is faded out at the same time,
The change in illuminance of the second lamp between the time when the second lamp is turned off and the time before the time corresponding to the time required for the first lamp to be turned on is approximately referred to as the change in illuminance of the first lamp. Since they coincide with each other, by making the illuminance changes of the first and second lamps coincide with each other as much as possible, it is possible to prevent the color change of the illumination from occurring as much as possible, and it is possible to perform fade-in and fade-out with a good feeling.

In addition, when the first and second lamps are faded out at the same time, the first lamp is at a time before a time corresponding to the time required for the first lamp to light up after the second lamp is turned off. Since it is turned off, the illuminance change can be made the same when the first and second lamps are faded out and when the lighting operation of the first and second lamps is faded in. There is no discomfort when the two lamps are faded in and out at the same time.

Furthermore, the time required for fade-in and fade-out when the first and second lamps are individually faded in or faded out is
Since it is made to coincide with the time required to fade-in or fade-out the second lamp at the same time, the operation feeling can be made the same when individually or simultaneously fade-in or fade-out is performed.

According to a second aspect of the present invention, the time required for reaching the maximum or rated illuminance when the first lamp is lit at the minimum illuminance that can be lit and an up operation is performed to increase the illuminance. Is made to coincide with the time required to fade in or fade out the first and second lamps at the same time, so that the illuminance is increased from the state where the first lamp is lit at the lowest illuminance that can be lit. The time when the illuminance is maximum or rated by the up operation is set to be the same as the time when the first and second lamps are faded in or faded out at the same time.
From the state where the lamp is lit at the lowest illuminance possible, the operation feeling when the illuminance is increased to the maximum or rated illuminance and the first and second lamps are faded in and faded out at the same time. The operation feeling can be made the same.
