Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a sunlight tracking and lighting device that irradiates sunlight onto a house protected from sunlight by a high-rise house.

[Background technology]

In recent years, as cities have become overcrowded, daylight has become extremely difficult to obtain. Particularly, in high-rise buildings 100 as shown in FIG. 13 and 1ξ-story houses 104 where sunlight can be significantly prevented by high-rise buildings 102 as shown in FIG. 14, restoring sunlight rights is an important issue. ing.

Data such as the latitude and longitude of the setting location, declination angle of the building (inclination angle with respect to the south), south direction, operating time, tracking start angle, etc., and position data of each lighting position are stored.

The control unit 80 controls display, input/output of operations, program calculations, and selects the lighting position to change the lighting position.

The drive control device 14 includes an azimuth angle drive control section 14a and an altitude angle drive control section 14b.

Each of the drive control units 14a and 14b receives the output signal of the calculation result from the correction calculation unit 82, converts the output signal into a pulse signal, and converts the output signal into a pulse signal for each pulse of the azimuth angle drive unit 1.28 and the altitude angle drive unit 12b. The motors 3B and 50 are driven.

The operating device 8 is installed at each lighting position,
As shown in FIG. 5, the ejection signal transmitted from the antenna of the operation part W8 is received by the antenna 96 provided on the support base 26, and the signal is received by the receiving part 98 provided in the control device 16. The received signal is sent to the control section 80 to control the sunlight reflecting device 10.

Here, the operation will be specifically explained using FIG. 2. In the figure, 20 and 22 are high-rise residential buildings facing each other, A1 to AII, respectively.

It is an 11-story building ranging from B1 to Bl+. Each house 2
On the roof of 0.22 is the opposite house 22.2.
A driving reflective bag W21°23 is installed at 0 to let in light.

It is now assumed that a calling signal is output from the operating device 8 of each room A5 of the house 20 and B3 of the house 22. Then,
This call signal is received by a receiving section 98 of the control device 16 connected to each driving reflector 23, 21 and enters the control section 80.

Lighting position A5. When daylighting at B8 is completed, daylighting is simultaneously carried out at the next called daylighting position. It should be noted that the lighting position is given priority to the position that is called first, and if there is no call, lighting is performed at a fixed point 86 in the courtyard between the houses 20 and 22 until the sun tracking is completed.

In FIG. 11, other peripheral functions will be explained.

The display unit 70 displays the year, month, day, time, solar temperature, direction, wind speed, etc., indicating the operating state of the device.

The operation unit 72 is turned on to drive the device.

The wind speed detection unit 90 works in conjunction with an anemometer 88 consisting of a wind speed generator fixedly installed on the support base 26 as shown in FIG. 5, and serves to stop the device when the wind speed increases abnormally.

The sensor unit 92 captures information such as the temperature and humidity necessary for the operation of the device, the reference line of the sunlight reflecting device 10, and whether the device is rotating beyond an allowable range.

Azimuth lock part 48. The altitude angle locking section 52 controls the azimuth angle driving section 12a,
Each pulse mortar 38, 50 of the altitude angle drive unit 12b is unlocked when rotating, and locked when the rotation is completed.

Further, FIG. 12 shows that low-rise houses 114, 116, 118, and 120 in the shadow of a high-rise building 112 are illuminated. That is, a solar reflector 210 is installed on the roof of a high-rise building 112 to direct sunlight to low-rise houses 114,
116, 118, and 120 are illuminated for a predetermined period of time in the order in which they are called.

In this way, in Figure 2, the lighting position is changed vertically, and the
In Figure 2, the change is made horizontally, and by combining the two,
It can also be changed diagonally.

According to the sunlight tracking daylighting device configured in this way, the main calculation unit 76 of the control device 16 calculates the position of the sun S, and the auxiliary calculation unit 82 calculates sunlight reflection from the position of the sun S and the daylighting position. Calculate the azimuth and altitude angle of the sunlight reflecting device 1O that directs sunlight reflected by the device 10 to the daylighting position, outputs the calculation results to the drive control device 14, drives the drive device 12, and directs the sunlight to the sunlight reflecting device 10. Change the angle of the light reflecting device 10.

Further, the lighting position can be changed by outputting a call signal from the operation unit W8 provided at the lighting position.

Therefore, daylighting can be performed at any position at any time.

Furthermore, by driving the sunlight reflecting device 10 with the drive device 12 and changing the azimuth and altitude angle, the lighting position can be changed, so one sunlight reflecting device 10 can illuminate a wide range. . In this way, one solar reflective bag R10 can illuminate a wide area, so the number of solar reflective devices 10 required is small, and the cost of reinforcing the building and installing it can be reduced, making it economical. It is true.

Moreover, since the weight of the solar reflecting devices 10 that can be installed on the rooftop is limited, when the number of solar reflecting devices 10 decreases, one solar reflecting device 10 can be made larger, and therefore the reflecting surface becomes larger. It is possible to introduce a large amount of light.

Furthermore, since the lighting position can be changed remotely using the operating device 8 provided at the lighting position, the operation is very easy. In addition, the lighting can be evenly illuminated for each predetermined period of time.

Note that the lighting position may be set in advance. That is, data such as the start and end of the lighting position, the number of lighting locations and their lighting order, and the lighting time at one lighting position may be input from the operation unit 72 and set in advance. .

〔Effect of the invention〕

According to the configuration of the present invention, the following effects can be obtained.

By controlling the angle of the sunlight reflecting device based on the position of the sun and the daylighting position by the calculation unit of the control device, it is possible to let in light at the daylighting position. Therefore, by setting the daylighting position and daylighting start time, daylighting can be carried out at any time and at any position.

Since the sunlight reflecting device is movable and the lighting position can be changed, a wide range of lighting can be achieved with one solar intensity 4.1 device.
