Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device having a dimming light source for dimming lighting and a non-dimming light source for on / off lighting.

[0002]

2. Description of the Related Art For example, in a lighting device for a room of a house, in order to create an atmosphere suitable for the purpose of use of the room,
Incandescent lamps and discharge lamps are used selectively.

Further, for example, when the incandescent lamp is turned on and off, it is gradually brightened from the off state to be turned on (fade in), or gradually darkened from the turned on to be turned off (fade out) to create an atmosphere. Therefore, there is an illuminating device that is dimmed and lit.

[0004]

By using a plurality of types of lamps such as incandescent lamps and discharge lamps together in a room, the atmosphere of the room can be selectively produced by lighting. Moreover, for example, when the incandescent lamp is dimmed and turned on, the effect of the atmosphere can be further enhanced.

However, for example, when both the incandescent lamp that performs light control and the discharge lamp that does not perform light control are turned on, the incandescent lamp gradually becomes bright from the unlit state when the lighting switch is turned on. Since the lamp will turn on all the light immediately, the effect of dimming the incandescent lamp on the atmosphere will be lost.

The present invention has been made in view of the above points, and is provided with a dimming light source that performs dimming and a non-dimming light source that does not dimming, even when both light sources are turned on. An object of the present invention is to provide an illuminating device capable of ensuring an effect of producing an atmosphere by dimming and lighting a light source.

[0007]

According to the present invention, there is provided a dimming light source and dimming means for dimming the dimming light source and for fading in and out when the dimming level is changed. A lighting device having a light source and a lighting means for lighting all the non-dimming light sources, wherein the dimming means controls the dimming means and the lighting means to light the dimming light source and the non-dimming light source, respectively. The control means is provided for turning on all lights of the non-dimming light source when the dimming lighting of the light source is completed.

According to a second aspect of the present invention, there is provided a dimming light source and dimming means for dimming the dimming light source and for fading in and out when the dimming level is changed. A lighting device having a lighting means for lighting all the light sources, wherein the dimming is for judging the ratio of the dimming lighting value for dimming the dimming light source to the maximum dimming lighting value of the dimming light source. When the ratio determining means and the dimming means and the lighting means are controlled to turn on the dimming light source and the non-dimming light source respectively, the non-dimming control is performed corresponding to the dimming rate determined by the dimming ratio determining means. And a control means for turning on all the light sources.

[0009]

According to the first aspect of the invention, the dimming light source is faded in from the unlit state so as to be gradually brighter to be dimmed and turned on, and the non-dimming light source is turned on to be fully dimmed. When each of the dimming light source and the non-dimming light source is turned on, all lights of the non-dimming light source are turned on corresponding to the completion of the dimming lighting of the dimming light source. Therefore, since the non-dimming light source is turned on when the dimming light source that is dimmed and turned on becomes the brightest, the effect effect of the atmosphere by the dimming lighting of the dimming light source is secured.

According to the second aspect of the present invention, the dimming light source is faded in from the unlit state so as to gradually become brighter and dimmed to be lit, and the non-dimming light source is lit to be fully dimmed. When turning on the dimming light source and the non-dimming light source,
The dimming ratio judging means judges the ratio of the dimming lighting value for dimming and lighting the dimming light source to the maximum dimming lighting value of the dimming light source, and the non-corresponding non-corresponding dimming ratio is judged. Turn on all lights of the dimming light source. Therefore, since the non-dimming light source is turned on when the dimming light source to be dimmed and turned on reaches a predetermined dimming lighting value, the effect effect of the atmosphere by the dimming and lighting of the dimming light source is secured, and Prevents deviation of the lighting timing of the dimming light source.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of an embodiment corresponding to the invention of claim 1 will be described below with reference to FIGS.

FIG. 1 shows a circuit diagram of an illuminating device, which includes an incandescent lamp 1 and a high-intensity lamp 2 as a dimming light source for performing dimming lighting and fading in and fading when the dimming level is changed. The discharge lamp 3 is provided as a non-dimming light source that performs full-light lighting without lighting. These light sources are placed in one fixture or installed in different places in the room. The dimming lighting is, for example, 5
It includes lighting at a dimming level with a brightness of 0% or the like and lighting at a full light level.

The incandescent lamp 1 and the high-intensity lamp 2 are connected to a commercial AC power source 4 via triacs 5 and 6 as dimming means, respectively. A series circuit including capacitors 7 and 8 and resistors 9 and 10 is connected in parallel with the triacs 5 and 6, respectively.

The discharge lamp 3 is connected to the lighting means 11 connected to the commercial AC power supply 4. This lighting means 11 is
It is composed of a triac 12 and an inverter lighting device 13. Reference numeral 21 is a starting capacitor.

A control means 14 is connected to each of the triacs 5, 6 and 12. The control means 14 variably controls the amount of electric power supplied to the incandescent lamp 1 and the high-intensity lamp 3 by the triacs 5 and 6, respectively.
The on / off control of the power supply to the discharge lamp 3 is carried out by. The control means 14 performs corresponding control based on the input of a command signal from a remote controller, a wall switch, a human body detection sensor or the like (not shown).

Next, the operation of this embodiment will be described.

Under the control of the control means 14, the incandescent lamp 1 and the high-intensity lamp 2 are faded in so as to gradually increase in brightness from the extinguished state, and are lit up to a predetermined dimming level or all-lighting level. The light is faded out from the lighting state so that the brightness is gradually reduced and then turned off.

The discharge lamp 3 is controlled by the control means 14 so that the discharge lamp 3 is turned off and then turned on and turned on.

Then, for example, the control by the control means 14 when the incandescent lamp 1 (or the high-intensity lamp 2 or both) and the discharge lamp 3 are turned on from the extinguished state will be described with reference to the flowcharts of FIGS. 2 and 3. explain.

When a lighting command is input to the control means 14 (step 1), the incandescent lamp 1 is dimmed and turned on (step 2).

When the incandescent lamp 1 is dimmed to a predetermined lighting state and the dimming is completed (step 3), the discharge lamp 3 is turned on (step 4).

Therefore, the incandescent lamp 1 gradually becomes brighter from the unlit state, and the discharge lamp 3 is lit at the brightest time, so that the effect of the atmosphere by the dimming lighting of the incandescent lamp 1 can be secured. it can.

When the light is turned off, it is preferable to turn off the discharge lamp 3 which does not perform dimming and simultaneously fade out the incandescent lamp 1 which performs dimming.

Although the discharge lamp is a non-dimming light source in this embodiment, another light source may be a non-dimming light source and the discharge lamp may be dimmed by an inverter to be a dimming light source.

4 and 5 show another embodiment of the present invention. In this embodiment, considering that the preheating time is required before the discharge lamp 3 is turned on, the discharge lamp 3 is turned on at the same time when the dimming lighting of the incandescent lamp 1 (similar to the high-intensity lamp 2) is completed. Control. It should be noted that, from the dimming time T from the extinguished state of the incandescent lamp 1 to the completion of dimming lighting and the preheating time t2 required for the discharge lamp 3, lighting from the start of dimming the incandescent lamp 1 to turning on the discharge lamp 3 is performed. Start time t
1 (T-t2) is preset.

When a lighting command is input to the control means 14 (step 11), the dimming lighting of the incandescent lamp 1 is started (step 12). When the lighting start time t1 has elapsed from the start of dimming, the discharge lamp 3 is turned on to start preheating (steps 13 and 14). Then, the dimming lighting of the incandescent lamp 1 is completed (step 15).

Therefore, the discharge lamp 3 can be turned on at the same time when the dimming lighting of the incandescent lamp 1 is completed.

Next, the structure of an embodiment corresponding to the invention of claim 2 will be described with reference to FIGS. 6 to 8.

As shown in FIG. 6, in this embodiment, as shown in FIG.
As a function of the control means 14 shown in FIG. 1, the ratio (%) of the dimming lighting value for dimming the incandescent lamp 1 or the like to the maximum dimming lighting value (100%) of the incandescent lamp 1 or the like for dimming lighting.
The function of the dimming ratio judging means 14a for judging is added.

Then, the control means 14 elapses from the start of the dimming lighting of the incandescent lamp 1 or the like to the time corresponding to the dimming ratio judged by the dimming ratio judging means 14a, that is, the incandescent lamp 1 or the like. Along with the completion of dimming lighting, discharge lamp 3
Control to turn on.

In addition, the lighting start time t1 of the discharge lamp 3 from the time when the dimming lighting of the incandescent lamp 1 etc. is started corresponding to the classification of the ratios judged by the dimming ratio judging means 14a and the respective classifications of the ratios. It is set. An example of this setting is shown in steps 22 and 23 of FIG. The lighting start time t1 is an example when the time T required for lighting the incandescent lamp 1 from 0% to 100% is 3 seconds.

When a lighting command is input to the control means 14 (step 21), the maximum dimming lighting value (100) of the incandescent lamp 1 (the same applies to the high brightness lamp 2) is caused by the function of the dimming ratio judging means 14a. %), The ratio of the commanded dimming lighting value is determined to be, for example, 50% (step 22). In addition,
When both the incandescent lamp 1 and the high-intensity lamp 2 are dimmed and turned on, and when either dimming ratio is large, the larger ratio is selected and determined.

Lighting start time t corresponding to the determined ratio
Set 1 (step 23). If the ratio is 50%,
Set to 0.7 seconds.

Then, the dimming lighting of the incandescent lamp 1 is started (step 24), and from that time, the lighting start time t1 of 0.
After 7 seconds, the discharge lamp 3 is turned on (step
twenty five).

Therefore, the discharge lamp 3 can be turned on at the time when 50% of the dimming lighting of the incandescent lamp 1 is completed. In this case, since the discharge lamp 3 is turned on after a certain time (for example, the time T corresponding to 100% turn-on of the incandescent lamp 1) is completed after the dimming lighting of the incandescent lamp 1 is completed, the discharge lamp 3 is turned on. It is possible to avoid misunderstanding and prevent abrupt lighting of 3 when it is not lit.
