EXAMPLES The present invention will be described below with reference to examples.

FIG. 1 shows a basic configuration of an embodiment of the present invention.
For example, lamps 1a, 1b, and 1c having different emission colors of R (red), G (green), and B (blue), and a clock function unit 2 having a timer function.
Then, the toning data storing the toning data as the dimming level data of each of the lamps 1a, 1b, and 1c is output to the storage unit 3 and an address for reading the toning data from the toning data storage unit 3 is output. Toning data address output section 4, toning data conversion output section 5 for converting toning data into dimming signals, and dimming lighting for inputting a dimming signal and dimming and lighting each of the lamps 1a, 1b, 1c. It is composed of devices 6a, 6b and 6c.

The toning data address output unit 5 outputs read address data of the toning data storage unit 3 according to the output from the clock function unit 2 corresponding to the time, and accordingly, the dimming read out according to the time. The toning data as the level data changes, and a dimming signal corresponding to the toning data is output from the toning data conversion output unit 5, and each of the dimming lighting devices 6a to 6a to
In 6c, the lamps respectively connected based on this dimming signal
Dimming lighting is performed for 1a to 1c.

Here, each lamp 1a, 1b, 1c is mixed by a milky white panel or the like to be one light source, and the light color of the illumination is obtained by this light source, and the dimming lighting is performed as described above. Thus, the color temperature of the light color of the illumination is changed according to the time.

Although the color temperature corresponds to the black body locus of the chromaticity coordinates by definition, only such a locus is rare, so it actually means a change in the correlated color temperature. The correlated color temperature is called a color temperature.

FIG. 2 shows a specific configuration in which the time is divided into three time ranges of morning, daytime, and night, and the color temperature is controlled in the three time ranges. Next, the specific configuration will be described.

First, when the output state is changed by the clock function unit 2 at time, for example, morning, noon, and night, a time data address output circuit 41 provided in the toning address data output unit 4 outputs a 2-bit signal according to each state. Set. That is, the outputs OUT1 and OUT2 are set as shown in the table below in correspondence with the respective time ranges corresponding to morning, daytime, and night.

On the other hand, a clock pulse signal having a constant period is generated from the clock pulse generator 42. The clock pulse signal is counted by the counter 43, and a 7-bit signal is output. The 7-bit signal, together with the 2-bit signal of the time data address output circuit 41, becomes address data for reading data from the toning data storage unit 3.

Here time data address output circuit 2 address input terminals A ₇ toning bit signals comprise PROM data storage unit 3, A ₈ of 41, also 7-bit signal is the address input terminals A ₀ of the counter 43 to A ₆ and outputs the data to the data output terminal of the toning data storage unit 3 based on the 9-bit address data.
D ₀ from to D ₂ each lamp 1a, 1b, so that the bit corresponding tone color data are read out to 1c.

Here, when the counter 43 counts up to 7 bits (128), it is reset and repeats the count, so that the toning data is output as the same repeated data, and the clock pulse signal of the clock pulse generator 52 is output. The above contents will be repeated with the time of the product of the cycle and the number of counts (128).

Accordingly, the toning data conversion output unit 5 repeatedly inputs toning data (a duty signal or the like is conceivable) to the conversion circuits 7a to 7c corresponding to the respective bits, converts the toning data into an analog signal by, for example, integration, etc. The dimming signals of the lighting devices 6a to 6c are created.

Of course, the dimming signal is created according to the control method of the dimming lighting devices 6a to 6c such as phase control and frequency control, and is not limited to the analog signal.

Thus, the lamps 1a to 1c are turned on at a dimming level corresponding to the dimming level which is the toning data. Here in the morning,
For example, the color temperature of daytime and nighttime is approximated to the color temperature of sunlight in the morning, daytime, and sunset (night).
R, G, B lamps 1a-1 to be 8000K in the day and 3000K at night
If the dimming data of c is stored in the toning data storage unit 3, the light color changes greatly depending on the time, and the sense of time can be represented by the main illumination.

FIG. 3 shows a circuit configuration of another embodiment of the present invention. In this embodiment, a clock pulse signal is output from the clock function unit 2 every 10 minutes, for example. Counter provided in part 5
It is made to count by 44, counter 44
Counts 24 × 6 = 144 clock pulse signals per day and is reset by counting 144 clock pulses.

Thus was thereby outputting 8-bit signal corresponding to the count value in the address data input terminals A ₀ to A ₇ of the tone color data storage section 3 as the address data from the counter 44. Therefore, the same address data is given to the toning data storage unit 3 at the same time every day, and toning data as dimming data corresponding to the time is output to the data output terminals D _{0 to} D _{3 of the} toning data storage unit _3.
Output.

This toning data is converted by the conversion circuit of the toning data conversion output unit 5.
The light is converted into a dimming signal by 7a to 7c and output to the dimming lighting device 6, and each of the lamps 1a to 1c is dimmed and lit by one dimming lighting device 6 at a predetermined dimming level.

In this way, in this embodiment, the dimming lighting level of the lamps 1a to 1c is changed, for example, every 10 minutes to change the light color by the color mixture, and it is fine and continuous like 5,000K in the morning to 8000K in the day to 3,000K in the night. The color temperature can be changed.

FIG. 4 shows a configuration of an embodiment in which the color temperature is set according to the season. In this embodiment, a time season data address output circuit is used instead of the time data address output circuit 41 in the circuit of FIG. 45 is provided in the toning data address output section 4, and the date / time signal output from the clock function section 2 is converted into 4-bit address data corresponding to the time season by the time / season data address output circuit 45. I have. In other words, two bits corresponding to the address data input terminals A ₇ and A ₈ of the toning data storage unit 3 cover the time ranges of morning, noon, and night, and address data input terminals A ₉ and A ₉ , as in the circuit of FIG. _The two bits corresponding to ₁₀ indicate the spring, summer, autumn, and winter seasons.

For example, a 4-bit signal corresponding to spring, summer, autumn, and winter morning is as shown in the following table.

On the other hand create an address data corresponding to the clock pulse generator 42 and the address data input terminals A ₀ to A ₆ of the counter 43 and the second drawing circuit similar to the tone color data storage section 3, these address data and time seasonal data The toning data is read from the address of the toning data storage unit 3 specified by the address data. The toning data has the same configuration as the circuit in FIG.
Are converted into dimming signals by the conversion circuits 7a to 7c, and supplied to the dimming lighting device 6. The dimming lighting device 6 dims and lights the lamp 1 based on the dimming signal. This lamp 1 is R, G,
In discharge path 1 _R, 1 _G, 1 _B respectively with and integrated composite lamp B, which is R, G, depending on the converted dimming data corresponding to the B set by the conversion circuit 5a~5c The light is lit by the respective discharge paths 1 _R , 1 _G , and 1 _B at the dimming level.

Thus, in the present embodiment, the light color is largely changed according to the season and time, and the sense of season and time can be expressed in a one-year cycle by the main illumination.

FIG. 5 shows a case where different toning data for the season and the time are separately set, and the corresponding lamps 1a are respectively set by different dimming lighting devices 6, 6 '.
-1c and 1a'-1c 'are provided for dimming and lighting. A seasonal counter 46 is provided in the dimming data address output section 4', and a time counter 47 is provided in the dimming data address output section 4. 2 bit seasonal address data and 8 bit time address data are respectively created based on the date and time signal. The toning data storage section 3 'corresponding to the season stores the toning data corresponding to the season, and the toning data storage section 3 corresponding to the time stores the toning data corresponding to the time.

The dimming control based on the read toning data is the same as that of the circuit shown in FIG.

In this embodiment, since the toning data of the season and the time are separately set and the lamps are lit by different lamps, for example, the light color of the main lighting is changed from 3000K to 8000K depending on the time, and the change is set to 1K. Repeat in the day cycle, set the color of the atmosphere (not the color temperature) for each season with indirect lighting, for example, light color such as pink in spring, blue in summer, etc.
Combine these main lighting and indirect lighting.

In any of the embodiments, the data in the toning data storage unit 3 may have any content as long as the color temperature of the entire light source changes in a one-day cycle or a one-year cycle, and may be in any order, continuous or discontinuous. In addition, any signal may be used as long as it converts and generates a dimming signal that can control the dimming lighting device 6, such as an analog signal, a duty signal, and a phase shift control signal corresponding to the toning data conversion output unit 5.

The dimming lighting devices 6 may be independent or integrated, and the means may be DC lighting, AC lighting, or high-frequency lighting.

Further, the lamp used may be any of a color discharge lamp, an incandescent lamp, a combination of a discharge lamp and a color filter, a color incandescent lamp and the like as long as a sufficient amount of light is obtained as the main illumination. But it is good.

Further, in each of the embodiments, the description has been made with reference to a change in color temperature of 3000 K to 8000 K.However, even if the light color atmosphere slightly deviates from the locus of the black body, the light color atmosphere of the main illumination is not uncomfortable.
