For example, in order to perform environmental tests on irradiated objects such as automobile-related parts, the irradiation environment close to the irradiation condition of sunlight in the room Can be made (see, for example, Patent Document 1 and Patent Document 2).

  Further, in such a simulated solar radiation device, when performing various tests for reproducing natural solar radiation on an object to be irradiated such as automobile-related parts, the object depends on the height of the object to be irradiated, that is, the object to be tested. When the distance between the DUT and the solar lamp changes, the amount of irradiation light varies. Therefore, the conventional simulated solar radiation device requires an operation for adjusting the irradiation distance according to the height of the test object.

  In order to achieve the object of realizing a pseudo-sunlight device that enables reduction in size and weight and energy saving, an object to be irradiated is installed in a pseudo-sunlight device that obtains illumination similar to natural solar radiation. A solar radiation chamber, a plurality of lamps arranged in a plane and provided on the upper ceiling of the solar radiation chamber, the solar radiation means capable of adjusting the amount of solar radiation by changing the amount of light by lighting of the lamp, and a predetermined solar radiation condition Correspondingly, it is realized by providing solar radiation control means for executing the solar radiation amount adjustment of the solar radiation means.

  Hereinafter, a preferred embodiment of the pseudo-sunshine device of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a side view showing a schematic configuration of a pseudo sunshine device according to the present invention. In the figure, the pseudo sunshine device 11 is an example of a test facility for reproducing natural solar radiation on an object to be irradiated such as an automobile-related part mounted on the body of the automobile 10.

  The pseudo-sunlight device 11 includes a solar radiation chamber 12 as a test room having a size capable of accommodating the automobile 10 to be tested as an irradiated object, and a chassis dynamo is provided on the floor of the solar radiation chamber 12. There is a meter roller, and the automobile 10 can be driven.

  The interior 13 of the solar radiation chamber 12 is a space that is thermally isolated from the outside. The opening 14 through which the automobile 10 enters and exits blocks air leakage in the solar radiation chamber 12, and the solar radiation chamber. An openable / closable shutter 15 is provided to maintain the airtightness in the inside 12.

  A solar radiation means 16, a ventilation device 17, and a guard member 18 are installed on the ceiling portion of the solar radiation chamber 12. In addition, operation | movement of the solar radiation means 16 and the ventilation apparatus 17 is controlled via the control part 19 as a solar radiation control means.

  The solar radiation means 16 has a substantially rectangular frame 21 suspended from a ceiling portion via a connecting member 20 constructed in the upper part of the solar radiation chamber 12, and a state in which the solar radiation means 16 is arranged in a plane on the lower surface of the frame 21 And a plurality of solar lamps (in this example, metal halide lamps are used) 22, 22...

  The ventilator 17 agitates the air in the ceiling portion of the solar radiation chamber 12 to eliminate heat accumulation, and averages the air in the solar radiation chamber 12. The ventilator 17 can exchange air in the solar chamber 12 with external air through a duct or the like.

  The guard member 18 is provided on the side where the automobile 10 enters the solar radiation chamber 12 and in front of the solar radiation means 16 and is sent to the solar radiation chamber 12. When the height of 10 exceeds the allowable height limit, the automobile 10 is further sent into the solar radiation chamber 12, and the automobile 10 collides with the solar radiation means 16 to cause the frame 21 or the lamp. It has a function of guarding the destruction of the group 23. As shown in FIGS. 2 and 3, the guard member 18 includes a pair of left and right rail-like members 24, 24 constructed on the upper part of the solar radiation chamber 12, and left and right 1 suspended from the rail-like members 24, 24. A guard rod 26 is horizontally provided between the pair of connecting members 25 and 25.

  Further, the height of the guard rod 26 from the floor surface is set slightly lower than the height of the lamp group 23 from the floor surface in order to restrict the height restriction of the automobile 10. Therefore, when the automobile 10 is sent into the solar radiation chamber 12 exceeding the height limit of the guard member 18, it can be known that the automobile 10 collides with the guard rod 26 and exceeds the height limit. The lamp group 23 can be protected from the automobile by preventing it from entering the solar radiation chamber 12 any more.

  In the pseudo sunshine device 11 configured in this way, the control is performed according to the stationary object sent to the sunshine chamber 12, that is, the height of the automobile 10, the sunshine condition, and the like. The unit 19 controls the voltage of the solar lamp 22 in the sunshine means 16 by means of an electric slider not shown, or controls the number of the lit lamps 22 in the sunshine means 16 by means of an open / close switch (not shown) to change the amount of light by the lamp group 23. Then, it is possible to execute solar radiation corresponding to the conditions without changing the height of the irradiated object (the automobile 10) and the solar radiation means 16 from the floor surface. As a result, the irradiation distance is adjusted by operating the solar radiation means in the vertical direction, which has been used in the conventional apparatus, or the irradiation distance is adjusted by operating the gantry of the solar radiation apparatus carrying the test object in the vertical direction. Mechanisms and devices are not required.

FIG. 4 shows an example of a lighting pattern switching parameter map used when executing solar radiation corresponding to the height of the object to be irradiated (automobile 10) and solar radiation conditions. In this parameter map, a lighting pattern 1 capable of creating a clear state, a lighting pattern 2 and a lighting pattern 3 capable of creating a cloudy sky state (the switching from pattern 2 to 3 is performed between the lamp and the specimen). In other words, the unevenness of the location within the switching guaranteed area is suppressed when the distance is not obtained.), And four maps of the lighting pattern 4 capable of creating a rainy weather condition are provided. In the parameter map, the height of the automobile 10 (9 types of FL + 750 to FL + 1501) is shown on the Y axis, and the amount of solar radiation (W / m ² ) required for patterning is shown on the X axis.

That is, in FIG. 4, for example, when performing an irradiation test with a solar radiation amount of 1000 W / m ² in the automobile 10 having a height of FL + 750, the solar radiation amount setting value is input with 1000 W / m ² on the touch panel screen, and the dimming height is set. The lighting pattern 1 is automatically selected by inputting a value of 750 mm (the lighting pattern 1 is selected when it is input within the solar radiation amount setting value 801 to 1163 W / m ² and the dimming height setting value FL + 750 to 825 mm). The light on the irradiation surface 1900W × 4800L of FL + 750 height is dimmed to 1000 W / m ² ± 15% (location unevenness accuracy) by control. (Even if the dimming height setting value FL + 826 to 1000 mm and the solar radiation amount setting value 833 to 1163 W / m ² are input, the dimming height setting value FL +1001 to 200 mm and the solar radiation amount setting value 871 to 1163 W / m ² are used. Even if it is input, the lighting pattern 1 is selected.) For example, when the irradiation test of the solar radiation amount 850 W / m ² in the automobile 10 whose height is FL + 1500 is performed, the solar radiation amount setting value is set to 850 W / m on the touch panel screen. ² inputs, dimming height setting value is input 1500mm, lighting pattern 3 is automatically selected, and the illumination on FL + 1500 height irradiation surface 1900W × 4800L is dimmed to 850W / m ² ± 15% by voltage control .

Hereinafter, similarly, the amount of solar radiation 465 to 1163 W / m ² at the irradiation surface height of the automobile 10 is arbitrarily generated by switching and controlling the voltage of the sunshine lamp 22 or the number of lighting corresponding to the lighting pattern switching parameter map. be able to.
