FIG. 1 is a configuration diagram of a lighting device according to a first embodiment of the present invention. In FIG. 1, the illuminating device of the first embodiment includes a light bulb color straight tube fluorescent lamp 1 and a narrow-angle spot lamp 2 as two types of lamps having different light distributions, and these are individually blinked / dimmed. It is configured to be connected to a controller 3 which can be operated. This incandescent color straight tube fluorescent lamp 1 is covered with a light transmitting / diffusing shade 4 at the lower side, and gives diffused light to the entire room. On the other hand, the narrow-angle spot lamp 2 illuminates the table surface and realizes a certain light between the centers. Each lamp is blinked and dimmed by the control means built in the controller 3, and the light distribution of the entire lighting device can be changed according to the dimming state of each lamp.

FIG. 2 is a block diagram showing the internal flow of the controller 3. The controller 3 inputs a calendar signal generator 5 that outputs a calendar signal 6, and inputs the calendar signal 6 to perform arithmetic processing internally, and outputs a dimming signal 8a, 8b corresponding to each lamp. A generator 7 and blinking / dimming devices 9a, 9b for blinking / dimming each lamp according to the dimming signals 8a, 8b are provided. That is, in FIG.
Since the brightness is individually changed in association with the dimming signals 8a and 8b which are output as a result of arithmetic processing based on the calendar signal 6, the light distribution can be changed as a whole of the lighting device.

FIG. 3A is a block diagram showing the internal structure of the dimming signal generator 7. Dimming signal generator 7
Includes a temperature measuring device 10 and a humidity measuring device 12, and a calendar information generator 14 using a temperature signal 11 and a humidity signal 13 created on the basis of temperature and humidity measurement data as input signals.
Then, arithmetic processing is performed together with the calendar signal 6, and dimming signals 8a and 8b for each lamp are output. Here, the calendar signal generator 5 may be a device having a timer function such as a timepiece. The temperature measuring device 10 and the humidity measuring device 12 use, for example, a thermistor sensor.

On the other hand, FIG. 3 (b) shows changes in the dimming ratios of the bulb color straight tube fluorescent lamp 1 and the narrow-angle spot lamp 2 with respect to the calendar information set inside the dimming signal generator 7. There is. In FIG. 3B, the horizontal axis represents the flow of time indicated by the calendar signal 6, and the solid line in the graph represents each lamp 1, when the temperature and humidity are at the average level (average temperature and average humidity of each month). 2 represents the change in dimming rate. The dashed line indicates when the temperature or humidity with respect to time is at the maximum or minimum level (average of maximum temperature and maximum humidity of each month, or average of minimum temperature and minimum humidity of each month). Shows the change of the dimming rate of. The dimming ratio of each lamp is 2 from the solid line that is the average level.
It changes with a shift amount of 0%.

The shift amount of the dimming rate of each lamp with respect to changes in temperature and humidity will be described below. Figure 4
FIGS. 4A and 4B show the shift amount of the dimming rate of each lamp with respect to changes in temperature and humidity. Figure 4
In (a) and FIG. 4 (b), the origin of the graph is shown in FIG.
When the point on the solid line in (b), that is, the temperature and humidity are at the average level, the shift amount of the dimming rate is represented as 0. The dimming rate of each lamp changes with a width of 10% and a total width of 20% with respect to changes in temperature and humidity. The shift amount of the dimming rate is obtained for a certain temperature and a certain humidity, and is shifted from the dimming rate of the average level of each lamp by the sum of the two. Therefore, the shift amount of the dimming ratio takes a value of −20% to + 20%.

As an example, the average temperature and the average humidity are 20.
℃, 60%, April calendar, actual temperature is 30
The case of 80 ° C. and 80 ° C. will be described below. The difference between the actual temperature and humidity and the average level is 10 ° C. in temperature and 20% in humidity. From FIG. 4A and FIG. 4B, the shift amount of the dimming ratio of the incandescent fluorescent lamp 1 is 7.5% with respect to changes in temperature and humidity. Therefore, the dimming ratio of the incandescent fluorescent lamp 1 is shifted higher than the dimming ratio at the average level by 15% of the sum of shift amounts with respect to changes in temperature and humidity. Similarly, the dimming ratio of the narrow-angle spot lamp 2 is shifted down by 15%. In FIG. 3 (b),
The average dimming rate of each lamp in April was 45% for the compact fluorescent lamp 1 and 55% for the narrow-angle spot lamp 2.
Therefore, the dimming ratio of the light bulb color fluorescent lamp 1 is set to 60%, and the dimming ratio of the narrow-angle spot lamp 2 is set to 40% by adding 15% of the shift amount.

FIG. 5 is a light distribution curve diagram when the light bulb color straight tube fluorescent lamp 1 and the narrow-angle spot lamp 2 are combined and turned on. When the brightness of each lamp is changed in association with the calendar information set from the calendar, temperature, and humidity as shown in FIG. 3B, the light distribution of the entire lighting device is as shown in FIG.

That is, in FIG. 7, since the lamps of each color individually change the brightness in association with the color temperature and the illuminance of the external light, it is possible to change the light color and the brightness of the lighting device as a whole.

FIG. 8 shows a method of controlling the light color and brightness in the lighting device of the second embodiment. When the color temperature of outside light is 2,500K or less, the light color of the illuminating device is fixed to 2,500K, and when it is 10,000K or more, the light color of the illuminating device is fixed to 10,000K. , Control the brightness ratio of each color lamp. Also, from 2,500K
