Skylights that use light ducts can only be used in rooms and corridors directly under the roof, and require a large amount of space in the attic, so there is a problem in terms of design freedom and cost.

Moreover, although the thing using a solar cell can change the brightness of LED lighting proportionally according to the electric power generation amount, it is influenced by the direction which a solar cell installs, and also to a solar panel. There is a problem that the amount of power generation falls greatly in the morning and evening when the irradiation angle of the sun rays becomes shallower.

Accurate determination of day and night by using a microcomputer has already been applied to street lights, but this only separates day and night, and the brightness and color of lighting continuously in the time zone of sunrise and sunset. There is a problem that is not supposed to change.

There is already an illuminating device that changes the illumination color according to the biological rhythm, but it simply switches between day and night with a timer and does not assume changing the color switching time according to the day length There is.

Therefore, an object of the present invention is to provide a blue sky skylight lamp that has a high degree of freedom of installation, controls the illumination time and brightness to resemble a skylight, and makes the illumination color match the biological rhythm.

The blue sky skylight lamp 1 according to claim 1 is an energy-saving illuminating device 4 including a daylight white LED 12 and a light bulb color LED 13 that can adjust brightness when using an LED, and outputs of the day white LED 12 and the light bulb color LED 13. The dimmer 11 can be adjusted independently of each other, the data holding unit 7 that holds data relating to the entry and exit of the sun at various locations throughout the year, and the sunrise and sunset times of the day are specified based on the data in the data holding unit 7 It has a sunrise / sunset time specifying unit 6 that performs, a color tone / light amount calculation unit 9 that calculates brightness and color that changes with time, and the dimmer 11 that controls according to the calculated brightness and color.

The blue sky skylight lamp 1 according to claim 2 can adjust the brightness and the energy-saving lighting fixture 4 including the organic EL that can change the color from sky blue to light bulb color, and its output and color when using the organic EL 16. The dimmer 11 is different from the first aspect except that it operates in the same manner.

The blue sky skylight lamp 1 described in claim 3 is a blue skylight by changing the plastic mold of the daylight white LED 12 from transparent to sky blue when the LED is used for the energy saving lighting fixture 4 and the color tone is more important than the energy saving performance. It is characterized by the lighting.

The blue sky skylight lamp 1 according to claim 4 divides the night into a night and a midnight at a preset bedtime Tb, and the midnight light is suitable for it (about 2 looks), and the light is slightly bright (about 10 looks). It is characterized in that it is illuminated so that the eyes familiar with indoor lighting can be seen.

According to the blue sky skylight lamp described in claim 1, it is possible to reliably illuminate the interior with a predetermined brightness or higher from the sunrise to the sunset determined by calculation, regardless of the season.
Also, in the morning and evening, by changing the brightness of the LED gradually according to the outdoors in fine weather, it eliminates the sense of incongruity when the energy-saving luminaires are completely turned on, and uses a light guide plate to make a surface light source Thus, the lighting can be made closer to a skylight.
Furthermore, by switching to daylight color LED in the daytime and light bulb color LED in the nighttime, it is adapted to the biological rhythm.

According to the blue sky skylight lamp described in claim 2, the same effect can be expected when the organic EL is used as when the LED is used. In the case of organic EL, since the system emits various colors and is surface emitting, the system configuration can be simplified. On the other hand, the disadvantages of organic EL are that the energy saving effect is inferior and the cost is high.

According to the blue sky skylight lamp described in claim 3, even when a daylight white LED is used as the light source, illumination with the same color tone as the skylight is possible by using a color conversion filter such as a sky blue plastic mold. Thus, the lighting can be made closer to a skylight.

According to the blue sky skylight lamp as claimed in claim 4, the glaze is illuminated at about 10 lux, so if it is just a moving corridor, it is bright enough for eyes accustomed to indoor lighting This saves you the trouble of turning on and off the lighting.

Hereinafter, an embodiment of the sunny skylight lamp 1 will be described with reference to FIGS. 1 to 5. The clear skylight lamp 1 is mainly installed in residential buildings 2 such as condominiums, and it is natural light like a skylight while being artificial light in a corridor where external light cannot be taken in in the daytime. At the same time, the lighting color is adapted to the biological rhythm at night.

As shown in FIG. 1, the clear skylight window lamp 1 is installed in a corridor or the like where no external light enters the building 2, and is supplied with power from a commercial power source. The main body control unit 3 and an energy-saving illuminator 4 connected thereto are used. Composed. The main body control unit 3 includes a microcomputer 5, a key input unit 8, and a dimmer 11.

As shown in FIG. 2, the microcomputer 5 includes a sunrise / sunset time specifying unit 6, a data holding unit 7, a color tone / light quantity calculating unit 9, and a clock unit 10.

The sunrise / sunset time specifying unit 6 uses the following calculation method in the “Estimation table of the arrival and departure of the sun of each place” in the science chronology (Non-patent Document 1), and uses the following calculation method. It is based on calculating sunrise and sunset times. However, since To, M, N, and n are large amounts of table data, approximate expressions that can be easily processed by a microcomputer may be used.
The data holding unit 7 holds a large amount of table data or approximate expression parameters.
Sunrise time (Tr) is Tr = To + MN * n
The sunset time (Ts) is Ts = To + M + N * n
To: Daily Tokyo sunrise or sunset times
M: Correction value that varies depending on the longitude of the residential area
N: Correction value that varies depending on the latitude of the residential area
n: Factor that varies depending on the length of day

The color tone / light quantity calculation unit 9 sends a signal of brightness and color according to the current time of the clock unit 10 to the dimmer 11 based on the sunrise sunset time provided from the sunrise / sunset time specifying unit 6.

When LEDs are used in the energy-saving lighting fixture 4, two kinds of LEDs, a daylight color LED 12 and a light bulb color LED 13, are used, and the daylight color LED 12 is applied with a sky blue filter 14 to change the daylight color to sky blue, and then the light of the light bulb color LED 13. And the light guide plate 15 to illuminate the hallway and the like. The dimmer 11 changes the color of the energy-saving lighting fixture 4 by dimming both LEDs independently.
On the other hand, when the organic EL 16 is used, the emitted light is used as illumination as it is. The dimmer 11 controls the color and brightness of the organic EL 16.

The brightness of the sunrise and sunset times is 300 lux according to the “Guidelines for Illuminance and Brightness” in Koyomi Handbook 2006.4 to 2008.4 (Non-patent Document 2), and the general indoor brightness (JISZ9110 (Non-patent Document 3)). According to “Table 17-Housing 1”, it is brighter than 100 looks). Therefore, it is appropriate for the energy-saving lighting fixture 4 to illuminate with brightness that meets indoor lighting standards, instead of adjusting to outdoor brightness in the daytime zone from sunrise to sunset.

Therefore, the illumination brightness in the daytime from sunrise to sunset is to be illuminated at a constant brightness according to the illumination standard of JISZ9110, and the brightness is designated in advance by the resident as shown in FIG. The brightness L can be adjusted.
However, since an actual skylight illuminates the interior in proportion to the brightness of the sky, it has a skylight atmosphere by giving a certain change even if not proportional to the brightness of the sky as shown in FIG. There is also a way to make it.
The former is advantageous from the viewpoint of energy saving, and the latter is advantageous in terms of feeling natural light, so that it can be selected according to the resident's preference.

According to the National Astronomical Observatory website, the duration of regular twilight is about 30 minutes in Tokyo, there is a difference of about 10% between Hokkaido and Okinawa, which have different latitudes, and there is a difference of 10% in summer and winter compared to spring and autumn. It is said.
Therefore, when actually measuring the brightness of the sky in the normal twilight time zone, the brightness increased geometrically from twilight in about 20 minutes before sunrise, and geometrical series in about 20 minutes after about 5 minutes after sunset. The measurement result of becoming dark and dim is obtained.
Therefore, as shown in FIG. 4 or FIG. 5, the energy-saving lighting fixture 4 changes geometrically from 2 lux to the specified brightness in 20 minutes before sunrise, and the specified brightness in 20 minutes from 5 minutes after sunset. Basically, it is changed geometrically from about 10 lux.
In addition, the time shown here (5 minutes and 20 minutes) may be corrected by about 10% in the case of Hokkaido and Okinawa having slightly different latitudes, or in summer and winter.

When the LED is used, as shown in FIG. 6, the daylight white LED 12 is turned on during the day, and the daylight white LED 12 is gradually darkened in the sunset, while the light bulb color LED 13 is gradually changed. By turning it on, it changes from white to light bulb color. The time zone in which the color is gradually changed is combined with the time zone in which the brightness is changed, so that there is no sense of incongruity.
On the other hand, in the case of the organic EL 16 that can change its own emission color, the light is adjusted so that it is simply changed from sky blue to light bulb color.
The same applies to sunrise.

From 25 minutes after sunset, the energy-saving luminaire 4 is caused to emit light at about 10 lux from the preset bedtime Tb.

The present invention also includes a case where only the brightness change is performed in the above dimming control and the color change is omitted.

Furthermore, the embodiment of the present invention is not limited to the above-described embodiment, and the scope of the idea of the present invention is, for example, a case where a sky blue LED which will be developed in the future is replaced with a combination of a daylight white LED and a sky blue filter. Needless to say, changes can be made without departing from the scope of the invention.

The skylight skylight lamp 1 according to the present invention cannot be installed in a condominium as a housing complex, a highly insulated single-family house, a house in a snowy country with snow on the roof, and the like. Will be realized. In particular, this lamp does not require a sensor to detect outside light, expresses natural changes in light in the morning and evening, and uses an illumination color that matches the biological rhythm, making it easy to install and highly simulated. Functions as a skylight.

Color-light amount calculating section 9, sunrise based on sunrise sunset time resulting from sunset time specifying section 6, and sent to the brightness and color signals a dimmer 11 according to the current time of the clock section 10, the dimmer 11 Controls the color and brightness of the organic EL 12.

When using the LED lighting fixture shown in the cited document 4 for the energy-saving lighting fixture 4, this system The control unit has the circuit configuration shown in FIG.

The brightness of the sunrise and sunset times is 300 lux according to the “Guidelines for Illuminance and Brightness” in Koyomi Handbook 2006.4 to 2008.4 (Non-patent Document 2), and the general indoor brightness (JISZ9110 (Non-patent Document 3)). According to “Table 17-Housing 1”, it is brighter than 100 looks). Therefore, it is appropriate for the energy-saving lighting fixture 4 to illuminate with brightness that meets indoor lighting standards, instead of adjusting to outdoor brightness in the daytime zone from sunrise to sunset.

Therefore, the illumination brightness in the daytime from sunrise to sunset is to be illuminated at a constant brightness according to the illumination standard of JISZ9110, and the brightness is designated in advance by the resident as shown in FIG. The brightness L can be adjusted.
However, since an actual skylight illuminates the interior in proportion to the brightness of the sky, it has a skylight atmosphere by giving a certain change even if not proportional to the brightness of the sky as shown in FIG. There is also a way to make it.
The former is advantageous from the viewpoint of energy saving, and the latter is advantageous in terms of feeling natural light, so that it can be selected according to the resident's preference.

According to the National Astronomical Observatory website, the duration of regular twilight is about 30 minutes in Tokyo, there is a difference of about 10% between Hokkaido and Okinawa, which have different latitudes, and there is a difference of 10% in summer and winter compared to spring and autumn. It is said.
Therefore, when actually measuring the brightness of the sky in the normal twilight time zone, the brightness increased geometrically from twilight in about 20 minutes before sunrise, and geometrical series in about 20 minutes after about 5 minutes after sunset. The measurement result of becoming dark and dim is obtained.
Therefore, as shown in FIG. 4 or FIG. 5, the energy-saving lighting fixture 4 changes geometrically from 2 lux to the specified brightness in 20 minutes before sunrise, and the specified brightness in 20 minutes from 5 minutes after sunset. Basically, it is changed geometrically from about 10 lux.
In addition, the time shown here (5 minutes and 20 minutes) may be corrected by about 10% in the case of Hokkaido and Okinawa having slightly different latitudes, or in summer and winter.

From 25 minutes after sunset, the energy-saving luminaire 4 is caused to emit light at about 10 lux from the preset bedtime Tb.

It goes without saying that the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention. In particular, the number indicating the brightness has a considerable range due to the residents' preference.

The skylight skylight lamp 1 according to the present invention cannot be installed in a condominium as a housing complex, a highly insulated single-family house, a house in a snowy country with snow on the roof, and the like. Will be realized. In particular, this lamp does not require a sensor to detect outside light, it is illuminated in the sky in the daytime to express natural light changes in the morning and evening, and it is also easy to install by providing appropriate illumination at night. And it functions as a high-quality simulated skylight.
