11 and 11.

[0004]

By the way, in such an illuminating device, for example, when the incandescent lamp 3 is in a faulty state due to its life or not installed, or when the incandescent lamp 3 is switched to the illuminating state, The light sources 1 to 3 are turned off, and the room becomes completely dark.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a light source that does not light up, and when an operation for lighting only the light source that does not light up is performed, It is an object of the present invention to provide an illuminating device in which the light source is turned off and it does not become completely dark.

[0006]

In order to achieve the above-mentioned object, in the invention of claim 1, an illumination state is set so that any one or a plurality of different light sources are selectively turned on. Lighting means for switching the lighting atmosphere, operation input means for performing an operation input for switching the illumination state of the lighting means, and lighting control for performing lighting control of a desired light source according to the operation input of the operation input means. Means and
The operation input means is provided with a lighting determination means for determining whether or not each light source is turned on, there is a light source which is determined not to be turned on by the lighting determination means, and only the light source which is not turned on is turned on. In that case, the lighting control means lights at least one lightable light source other than the non-lighted light source.

According to the second aspect of the present invention, the lighting control means can sequentially and cyclically switch a plurality of lighting modes for lighting one or a plurality of light sources in response to a predetermined operation input from the operation input means. In the lighting device, when there is a light source that is determined not to be turned on by the lighting determination means, and the mode for turning on only the light source that is not turned on is in the lighting control mode, the lighting control means turns on the light source that is not turned on. The mode is skipped and the lighting control is sequentially and cyclically performed to achieve the above object.

For example, as described in claim 3, in the illumination device, the operation input means is a remote controller, and the lighting control means is provided with a receiving means for receiving a remote controller signal from the remote controller. 1 or claim 2
When applied, the effect is effectively exhibited.

[0009]

According to the invention of claim 1, by configuring as described above, even when there is a light source that does not light up, and when an operation to light only the light source that does not light up is performed, another light source is turned on. In this way, all the light sources are turned off so that it does not become pitch dark.

According to a second aspect of the invention, in a lighting device capable of sequentially and cyclically switching a plurality of types of lighting states for lighting one or a plurality of light sources, by skipping a mode for lighting a light source that is not illuminated, By turning off all the light sources so that it does not become pitch black, and by skipping the mode that is unnatural,
The operation feeling is the same as in the normal state.

[0011]

FIG. 1 shows an embodiment of the present invention. In the case of the present embodiment, in addition to the conventional lighting device shown in FIG. 3 described above, lighting detection circuits 12 to 14 that individually detect the lighting states of the light sources 1 to 3 are provided, and these lighting detection circuits 12 to 14
Is characterized in that the signal processing circuit 4 performs the following processing according to the detection output of

First, the operation when all the light sources 1 to 3 are normal will be described. When the receiving circuit 4 receives a remote control signal from a remote controller or the like, the signal processing circuit 5 determines which of the light sources 1 to 3 is to be turned on from the received output, and the lighting control circuits 6 to 8 according to the determination result. Under the control of any one of the lighting circuits 9 to 11 operates, and the specific light sources 1 to 3 are turned on. At this time, the outputs of the lighting detection circuits 12 to 14 provided for the respective light sources 1 to 3 are output to the signal processing circuit 5.
To the lighting detection circuit 12 in the signal processing circuit 5.
The output of the above-mentioned lighting control commands are compared with the lighting control commands given to the lighting control circuits 6-8. In this case, since the light sources 1 to 3 are all normal, the lighting control command and the lighting detection circuits 12 to 1
4 is the same as the output.

Next, a case will be described in which any one of the light sources 1 to 3 is in a faulty state due to its life or lack of mounting. Note that the following description will be made by taking the case where the incandescent lamp 3 is in a faulty state as an example. For example, if a remote control signal for switching only the incandescent lamp 3 from the state where the fluorescent lamp 1 is turned on is received, the signal processing circuit 5 turns off the fluorescent lamp 1 and turns on the incandescent lamp 3 as well. The lighting control command of is given to each lighting control circuit 6 and 8, the operation of the lighting circuit 9 is stopped, and the lighting circuit 1
The operation 1 is started. However, in this case incandescent lamp 3
Is not lit, the detection output of the lighting detection circuit 14 becomes a signal state indicating that the incandescent lamp 3 is in a faulty state. Therefore, the signal processing circuit 5 can determine that the incandescent lamp 3 is in the imperfect state, and at this time, for example, both the fluorescent lamp 1 and the incandescent lamp 2 are turned on.

An alarm sound generation circuit for generating an alarm sound is provided, and when any of the light sources 1 to 3 is in the defect or unmounted state as described above, the alarm sound is controlled under the control of the signal processing circuit 5. It is desirable that the generator circuit emits a warning sound to inform the user of the abnormality. The above operation is the incandescent lamp 2
Alternatively, when the fluorescent lamp 1 has no spot, the same operation is performed, and when the receiving circuit 4 receives the remote control signal for turning on only the spot light sources 1 to 3, the signal processing circuit 5 outputs another light source. The control is performed so that the light is turned on. FIG. 2 shows the operation of the lighting device when the incandescent lamp 3 has no defect.

In other words, in the present embodiment, at least one of the light sources is a defect, and when a signal for turning on only that light source is input, another normal light source is turned on. Therefore, the lighting device is not completely turned off during the switching operation of the light source. Note that, for example, when the incandescent lamp 3 has no defect, when a plurality of light sources including the incandescent lamp 3 are turned on, the lighting control command for the incandescent lamp 3 and the output of the lighting detection circuit 14 do not match. Regarding the incandescent lamp 2 or the fluorescent lamp 1 or both, the lighting control command and the output of the lighting detection circuit 12 or 13 match. Therefore, in this case, incandescent lamp 2 or fluorescent lamp 1
Or both lights up.

By the way, when the lighting control of each of the light sources 1 to 3 is performed by so-called fade-in or fade-out operation in which the brightness is gradually changed to be extinguished or shifted to a rated lighting state, lighting detection of a light source having a defect is detected. The timing may be set during the fade-in and fade-out operations. Further, when turning off one of the light sources and turning on the other light source, the light source to be turned off may be turned off after it is confirmed that the light source to be turned on is turned on.

(Embodiment 2) In the above-mentioned embodiment, the lighting device is capable of selectively controlling the lighting of any light source. However, in this kind of lighting device, the lighting of the light source is controlled in a progressive manner. is there. For example, fluorescent lamp 1 → incandescent lamp 2 → incandescent lamp 3
→ It corresponds to the case where the fluorescent lamp 1 is controlled.

In such a case, for example, when the incandescent lamp 3 has no defect, the lighting control of the incandescent lamp 3 is skipped and the lighting is sequentially controlled in the following order: fluorescent lamp 1 → incandescent lamp 2 → fluorescent lamp 1. To By doing so, it is possible to avoid the problem that the lighting device is completely turned off even in the lighting device in which the lighting of the light sources 1 to 3 is controlled in a sequential manner. In the present embodiment as well, a warning sound is emitted and the light sources 1 to 3 are given to the user.
It is desirable to inform that either of these is faulty or not mounted. Further, the forward feed control may be performed not only by remote control operation but also by operation such as wall switch operation. For example, once turn off the power with the wall switch,
When the power is turned on again after a fixed time (for example, about 1 to 2 seconds), even in the case of the operation of shifting to the next lighting mode,
This embodiment can be applied.

(Embodiment 3) It is conceivable that the above-described forward feed control includes a mode in which all the light sources are turned off (hereinafter, referred to as extinction mode). For example, the case where control is performed in the order of fluorescent lamp 1 → incandescent lamp 2 → incandescent lamp 3 → extinction → fluorescent lamp 1 corresponds to that. In the lighting device, for example, when the incandescent lamp 3 is a spot, the lighting state is as follows: fluorescent lamp 1 → incandescent lamp 2 → extinction → extinction → fluorescent lamp 1. Therefore, in the lighting device in which such a sequential feeding control is performed, the operation control of the lighting device may be performed such that the lighting control of the fluorescent lamp 1 → the incandescent lamp 2 → the extinction → the fluorescent lamp 1 is performed.

In this way, it is not necessary to give the user the feeling of being extended due to the repetition of the dark mode, and it is possible to obtain the same operational feeling as in normal operation. It should be noted that this point has the same advantage as in the case of the second embodiment. By the way, in Japanese Unexamined Patent Publication No. 4-206298, a main illumination such as a fluorescent lamp and a miniature ball as an auxiliary illumination are provided, and the main illumination (all lighting) →
Main lighting (dimming lighting) → Bean ball → Main lighting (all lighting) In the lighting device that is controlled to be turned on in sequence, if the beans are not installed,
It has been proposed to omit the lighting mode of the miniature ball, such as main lighting (all lighting) → main lighting (dimming lighting) → main lighting (all lighting). This illuminating device has an advantage that the illuminating device is not turned off in the mode in which the miniature ball should originally be turned on.

However, in this illuminating device, the above-mentioned lighting control is performed in accordance with the presence or absence of the miniature ball, and no consideration is given to the case where the main illumination is imperfect. It does not relate to a lighting device that combines and switches the atmosphere of the lights in the room.

[0022]

According to the first aspect of the invention, the illumination is composed of a plurality of different types of light sources as described above, and the illumination state is switched so as to selectively turn on any one or a plurality of light sources. Means, operation input means for performing an operation input for switching the illumination state of the illumination means, lighting control means for performing lighting control of a desired light source according to the operation input of the operation input means, and each light source is turned on. In the case where there is a light source that is determined not to be lit by the lighting determination means, and an operation input for turning on only the light source that is not lit is made by the operation input means. Since the lighting control means lights at least one lightable light source other than the non-lighted light source,
Even if there is a light source that does not turn on, and when an operation is performed to turn on only the light source that does not turn on, one of the other light sources can be turned on, and all the light sources will not turn off and it will not be pitch black. .

According to a second aspect of the present invention, the lighting control means can sequentially and cyclically switch a plurality of kinds of lighting modes for lighting one or a plurality of light sources according to a predetermined operation input of the operation input means. In the lighting device, when there is a light source that is determined not to be turned on by the lighting determination means, and the mode for turning on only the light source that is not turned on is in the lighting control mode, the lighting control means turns on the light source that is not turned on. The lighting mode is skipped and the lighting control is performed sequentially in a cyclic manner. Therefore, in a lighting device capable of cyclically switching a plurality of types of lighting states in which one or more light sources are turned on, a light source that is not turned on is turned on. It can be skipped, all light sources are turned off, it does not turn black, and there is a sense of incongruity. It is skipped, the normal time and the same operation is obtained.
