When a determination result indicating that there is a remote control input is output from the determination unit 351c by switching a switch or the like to the input line, the switch may be switched to the remote control receiver 351 side.

Regarding other structures, the second structure shown in FIG.
The function of the corresponding configuration of the embodiment is basically the same.

The operation of the device according to the third embodiment will be described. The power switch 369 is turned on with the plug P turned on. Then, do you want to configure
The operation content differs as follows depending on whether to reproduce the lighting with the content already registered.

That is, when lighting is to be performed with the contents already registered, the channel switches 3641 to 3643 are used.
Is turned on for less than a predetermined time. The determination unit 347 receives the signal from the timer 346 that has counted this ON time, determines that the read mode is specified, and outputs the read instruction signal to the combined signal generation unit 344 for selecting the corresponding LCD together with the corresponding channel instruction data. , And output to the memory control unit 348,
Further, the read instruction signal is guided to the addition / subtraction unit 341 and the switch 349 to inhibit the output of the addition / subtraction unit 341 and switch the switch 349 to the conduction side. The memory control unit 348 outputs the set luminance data of red, green, and blue from the designated channel storage area in the memory 345 to the output adjustment unit 38 via the switch 349 based on the channel instruction data and the read instruction signal. As a result, the output adjustment unit 38
Performs power adjustment of the power supply power based on the set luminance data, and supplies the adjusted power to each of the light bulbs 33R to 33B.

On the other hand, when performing setting, first, when registering the setting contents, as described above, first, a desired switch among the channel switches 3641 to 3643 is turned on for a predetermined time or longer, and A color LCD for referencing and displaying a mixed color is specified, that is, a channel to which luminance data after the setting operation is registered is specified.

In the manual light control mode without registration, the channel switch is not turned on without operating.
The result of the manual operation of the up / down key of the operation unit 36 is directly transmitted from the addition / subtraction unit 341 to the switch 34.
9 through the output adjusting unit 38,
Lighting display of 3R to 33b is performed. In the case of the manual dimming mode, the set value immediately before the addition / subtraction unit 341 is directly guided to the output adjustment unit 38, and the power switch 369 is turned off to prevent a problem that the lighting display is suddenly performed with high luminance. A reset means (not shown) is provided to reset the value of the addition / subtraction unit 341 to 0 every time.

In the registration mode, the display unit 37 is operated based on the luminance data of each color obtained by operating the up and down keys of each color in the operation unit 36.
The composite color display is performed on the LCD corresponding to the designated channel in the above, and the switch 349 is opened, and the contents being set are not output to the output adjustment unit 38 (the light bulb is not turned on).
Like that. The contents in the middle of the setting are output to the output adjustment unit 3.
8 to cause the light bulb to perform mixed color display during light control.

Subsequently, registration of the set luminance data is performed by turning on a channel switch of a designated channel for a predetermined time or more. Preferably, in order to confirm the registration, a display change such as blinking or extinguishment is given to the corresponding LCD, or a separate audio output unit is provided, and the LCD is responded to a write instruction signal from the memory control unit 348. In addition, a channel notification unit for generating a voice guide such as “registration completed” or a guide buzzer sound may be provided.

By the above operation, in the third embodiment,
It is possible to set and register dimming data for channels No1 to No3. When changing the registered content, it is possible to specify the channels that can be deleted and update them. By allowing the update registration in this way, it is possible to prepare more channels than necessary. Therefore, it is possible to substantially set and register various types of light control data.

FIG. 6 shows a fourth embodiment of the toning illumination device according to the present invention.
1A is a diagram for explaining a schematic configuration of an arrangement, and FIG. 1B is a diagram illustrating a structure of an operation panel unit.

The toning illumination device shown in the fourth embodiment is similar to that of FIG.
As shown in FIG. 3A, three (units 1 to 3) units are arranged on the ceiling, and the operation panel unit 45 is a wall surface and is provided at a required height position where operation is easy. . Further, inside each translucent diffusion cover 41, one having the same structure as the electric bulb and the color filter shown in the first to third embodiments is disposed.

The operation panel unit 45 shown in FIG. 6B is basically the same as the operation panel 35, and the internal circuit blocks have the same configuration as that of the third embodiment shown in FIG. However, the operation panel 45 is provided with selection switches 491 to 493 for selecting the units 1 to 3. Each selection switch has an on / off section, and one of the switches can be selectively pressed. A light emitting element such as an LED is built in corresponding to each of the ON and OFF portions, and the light emitting element on the pressed side is illuminated.
It is easy to recognize whether or not all of them are in the ON operation state.

Also, memories for storing the set luminance data are provided corresponding to the units (three in this embodiment,
Alternatively, one memory area is divided into three).
When data is stored, the selection switch 49 is set so that the data is written to the memory corresponding to the selected unit.
The unit changeover switch may be operated in conjunction with the operation to 1, 492, 493, or a chip select signal may be generated to write and read the corresponding memory. When outputting (lighting) to a plurality of units, each output data may be guided to an output adjustment unit provided correspondingly. Alternatively, the control unit may be provided for each unit.

Further, the present invention can be implemented in the following modified embodiments.

(1) In the second to fourth embodiments, the memory contents are updated at the registration timing. However, during the registration mode, the update of the output contents from the adding / subtracting unit is constantly repeated at predetermined time intervals. The update may be automatically terminated, that is, data storage may be terminated by a registration instruction operation at the time or when the value of the addition / subtraction unit is no longer changed. In this case, writing and reading to and from the memory ( Output) alternately, during the setting operation, the mixed color corresponding to the immediately preceding setting contents is changed to L
Reference display can be performed on a CD or the like, which is convenient for setting a new mixed color.

(2) Further, the present invention is not limited to the use of three color filters of red, green, and blue for three bare light bulbs. Red, orange, yellow, yellow-green, green, blue, indigo, violet or other light bulbs are provided and color filters of intermediate colors of the above colors are used. By doing so, it becomes possible to obtain various illumination color lights. In this case, a color designation key for individually instructing lighting and extinguishing may be provided instead of the up and down keys shown in the second to fourth embodiments.

The resin used for the coating material as the color filter of the present invention includes, for example, acrylic resin, polycarbonate resin, polystyrene resin, polyester resin, epoxy resin, polypropylene resin, polyethylene resin, silicone elastomer, and polystyrene thermoplastic resin. Resins such as elastomers, polyolefin-based thermoplastic elastomers, and polyurethane-based thermoplastic elastomers can be used, and among them, silicone-based elastomers and the like are preferably used. For example, a red color filter (cap) is a commercially available bee in which an organosiloxane and an additive and a plasticizer are blended as a reinforcing material, and a commercial name of SH851U (manufactured by Dow Corning Toray Co., Ltd.) is used.
To 2.5 parts by weight, 2.5 parts by weight of 2.5 dimethyl 2.5 dihexane and 0.5 parts by weight of bengara are mixed and kneaded with an open roll mixer to obtain a molding material. A mold that has been heated at a temperature of 170 ° C. for 10 minutes and formed at a pressure of 100 kgf / cm〓 and vulcanized is employed.

As the red coloring material mixed therewith, red iron red, cadmium red, red lead, cadmium mercury sulfide, permanent red 4R, lithol red, pyrazolone red, and watching red can be used.

Further, as a green coloring material, chrome green, chromium oxide, pigment green B, malachite green lake, fannal yellow green G, and the like can be used.

As the blue coloring material, indigo, cobalt blue, phthalocyanine blue, metal-free phthalocyanine blue, partially chlorinated phthalocyanine blue, fast sky blue, indaslen blue BC and the like can be used.

Further, as the silicone rubber, in addition to the above, for example, KE951U (manufactured by Shin-Etsu Chemical Co., Ltd.), TSE-
221-5U (manufactured by Toshiba Corporation) or the like can be employed.

(3) The light source may be an LED, a fluorescent lamp, or a light emitting diode instead of a light bulb, and is not particularly limited as long as it emits visible light. The shape of the color filter is easy to manufacture by molding it into a shape that can be easily attached to and detached from the external shape of a light source such as a light bulb, LED, fluorescent lamp, light-emitting diode, and the like. In addition, when the bulb is deteriorated and its life is long, it is easy to remove the color filter and fit it into a new bulb after the replacement, so that the color filter can be effectively used.

(4) Further, in an embodiment employing an LED,
Any known LED can be used. For example, Ga: ZnO red LED, GaP: N green LED, Ga
AsP red LED, GaAsP orange / yellow LED,
GaAlAs LED, InGaAlP orange / yellow LE
D, GaN blue LED, SiC blue LED, II-VI group blue LED and the like.

(5) In this embodiment, the set luminance level data is described as having a constant value in the time direction. However, the present invention is not limited to this. In consideration of the above, the luminance and the mixed color may be changed in the time direction with the set value individually (that is, the color), as the overall luminance, or in a form in which both are combined. For example, a function signal generating means for automatically generating a level regulation signal that fluctuates in a time direction with respect to a set value or a function (a sine wave, a triangle, a trapezoid, a pulse, or a more complicated waveform) generated in advance. Or a random signal generating means for outputting a signal from the means for limiting the level using an irregular wave formed randomly each time to the output adjusting sections 28 and 38 during reproduction. Then, a level limiting operation function (for example, a method of providing a power transistor and controlling the base voltage thereof) may be added to the output adjustment units 28 and 38. Alternatively, a write address (memory capacity) in the time direction may be prepared in the memories 245 and 345 and written at the time of setting registration. In this case, a desired function is designated by a function designation key or the like (not shown). To get it,
The memory control units 248 and 348 may write the set luminance level for each light source adjusted by the up and down keys in the memories 245 and 345 in accordance with the designated function. At the time of reading, the data can be reproduced by sequentially reading out to the output adjusting units 28 and 38 according to the written address.

(6) In the present embodiment, the description has been made by adopting, for example, a white light bulb having the same shape. However, the present invention is not limited to this. It is possible to adopt different colors. For example, at least one of the light sources emits light other than white light, and the other light source that emits light other than white light is mixed with a phosphor that changes the emitted light to white and emits light again. The color filter may be covered after the resin cap is once changed to white by covering with the resin cap. If you do this,
The types of light sources that can be used can be widened, and the light source can be made versatile.

Alternatively, it is not necessary to set the reference color to white. For example, when all red LEDs and light-emitting diodes are used, a phosphor to be changed to white and re-emitted is mixed in every one except for one. The color filter may be covered after the resin cap is once changed to white by covering with the resin cap. Alternatively, a resin cap mixed with a phosphor for re-emission directly from red to green and blue may be covered as a color filter.

That is, if a luminescent color is adjusted to white by attaching or forming a cap or coating layer for re-emission, a desired luminescent color can be obtained by using a coloring agent. In this case, the colorant may be contained in the cap or the coating layer together with the fluorescent substance, or another cap or coating layer containing the colorant may be further attached or formed thereon.

As the colorant, for example, as a yellow pigment, there may be used graphite, zinc yellow, cadmium yellow, yellow iron oxide,
Mineral fast yellow, nickel titanium yellow,
Navels Yellow, Naphthol Yellow S, Hansa Yellow G, Hansa Yellow 10G, Benzidine Yellow G, Benzidine Yellow GR, Quinoline Yellow Lake, Permanent Yellow NCG, Tartrazine Lake; Red-mouthed lead, molybdenum orange as orange pigment,
Permanent Orange GTR, Pyrazolone Orange, Vulcan Orange, Indus Ren Brilliant Orange R
K, benzidine orange G, indathrene brilliant orange GK; red pigments include condensed azo pigments, bengara, cadmium red, leadtan, mercury sulfide cadmium, permanent red 4R, lithol red, pyrazolone red, watching red calcium salt, lake red D, brilliant carmine 6B, eosin lake, rhodamine lake B, alizarin lake, brilliant carmine 3B; violet pigment, manganese purple, fast violet B, methyl violet lake; blue pigment, navy blue, cobalt blue, alkali blue lake, Victoria blue Lake, phthalocyanine blue, metal-free phthalocyanine blue, phthalocyanine blue partially chlorinated product, first sky blue, indaslen blue B
C: as a green pigment, chrome green, chromium oxide, pigment green B, malachite green lake, fanal yellow green G; as a white pigment, zinc white, titanium oxide, antimony white, zinc sulfide; as a white pigment,
Barite powder, barium carbonate, clay, silica, white carbon, talc, alumina white and the like can be used.
The colorant is preferably used in an amount of 0.001 to 0.1 part by weight, particularly 0.01 to 0.05 part by weight, per 100 parts by weight of the binder resin.

By employing such a cap and a coating layer, it is possible to finely adjust the emission color. For example, it is possible to convert an LED out of an allowable range caused by manufacturing variations into a color within the allowable range. Referring to Production Example 34, for example, when the current flowing through the blue LED is 5 mA, Y
10.0 parts of the AG phosphor, 10.5 parts when the current is 10 mA, and 11.0 parts when the current is 20 mA
, Chromaticity coordinates x = 0.2886 to 0.3046, y = if the fluorescent color cap containing 11.5 parts is attached to the LED when the current is 30 mA, respectively.
The desired emission color in the range of 0.3102 to 0.3165 can be obtained.
